The media is filled with stories about the opioid crisis. We have all heard the horror stories of addiction and overdose, as well as “pill mill” doctors. In fact, more than 932,000 people have died of drug overdose since 1999 and, in recent years, approximately 75% of drug overdoses involved opioids.

Dr. Linda Girgis

Yet, they still have their place in the treatment of pain. It has been estimated that approximately 37% of all opioid prescriptions are written by primary care doctors, so it is essential that we doctors know appropriate prescribing guidelines.

The CDC updated the 2016 guidelines for prescribing opioids for pain in 2022. They cover when to initiate prescribing of opioids, selecting appropriate opioids and doses, and deciding the duration of therapy. The guidelines do a great job providing evidence-based recommendations while at the same time keeping the problems with opioids in the picture.

For primary care doctors, pain is one of the most common complaints we see – from broken bones to low back pain to cancer pain. It is important to note that the current guidelines exclude pain from sickle cell disease, cancer-related pain, palliative care, and end-of-life care. The guidelines apply to acute, subacute, and chronic pain. Pain is a complex symptom and often needs a multipronged approach. We make a mistake if we just prescribe a pain medication without understanding the root cause of the pain.

The guidelines suggest starting with nonopioid medications and incorporating nonmedicinal modes of treatments, such as physical therapy, as well. Opioids should be started at the lowest dose and for the shortest duration. Immediate-release medications are preferred over long-acting or extended-release ones. The patient should always be informed of the risks and benefits.

While the guidelines do a great job recommending how to prescribe opioids, they do not go into any depth discussing other treatment options. Perhaps knowledge of other treatment modalities would help primary care physicians avoid opioid prescribing. When treating our patients, it is important to educate them on how to manage their own symptoms.

The guidelines also advise tapering patients who may have been on high-dose opioids for long periods of time. Doctors know this is a very difficult task. However, resources to help with this are often lacking. For example, rehab may not be covered under a patient’s insurance, or it may be cheaper to take an opioid than to go to physical therapy. Although the recommendation is to taper, community assets may not support this. Guidelines are one thing, but the rest of the health care system needs to catch up to them and make them practical.

Primary care doctors often utilize our physical medicine, rehabilitation, and pain management specialists to assist in managing our patients’ pain. Here too, access to this resource is often difficult to come by. Depending on a patient’s insurance, it can take months to get an appointment.

In general, the current guidelines offer 12 key recommendations when prescribing opioids. They are a great reference; however, we need more real-life tools. For many of us in primary care, these guidelines support what we’ve been doing all along.

Primary care doctors will surely play a huge role in addressing the opioid crisis. We can prescribe opioids appropriately, but it doesn’t erase the problems of those patients who were overprescribed in the past. Many still seek out these medications whether for monetary reasons or just for the high. It is often easy to blame the patient but the one in control is the one with the prescription pad. Yet, it is important to remember that many of these patients are in real pain and need help.

Often, it is simpler to just prescribe a pain medication than it is to explain why one is not appropriate. As primary care doctors, we need to be effective ambassadors of appropriate opioid prescribing and often that means doing the hard thing and saying no to a patient.

Watching feasible for asymptomatic kidney stones

Article Type
Changed
Tue, 05/09/2023 - 18:03

Many patients with asymptomatic renal stones can qualify for an active surveillance program, Swiss researchers report at the American Urological Association 2023 Annual Meeting.

Kevin Stritt, MD, chief resident in the urology department at Lausanne University Hospital, said kidney stones often pass without symptoms. But until now, data on the frequency of asymptomatic, spontaneous passage of stones have been lacking.

The new data come from the NOSTONE trial, a prospective, multicenter, double-blind, placebo-controlled randomized trial to assess the efficacy of hydrochlorothiazide in the prevention of recurrence in patients with recurrent calcium-containing kidney stones.

Dr. Stritt and colleagues evaluated the natural history of asymptomatic renal stones during a median follow-up of 35 months. “We found for the first time that a relevant number of kidney stone passages [39%] were asymptomatic, spontaneous stone passages,” Dr. Stritt told this news organization.

All asymptomatic spontaneous stone passages were analyzed in a comparison of the total number of kidney stones on low-dose, nonintravenous contrast CT imaging at the beginning and end of the 3-year follow-up.

Of the 403 stones passed spontaneously, 61% (245) were symptomatic stone passages and 39% (158) were asymptomatic stone passages, Dr. Stritt told this news organization.

Asymptomatic stones were a median size of 2.4 mm, and symptomatic stones were 2.15 mm, which was not significantly different (P = .366), according to the researchers. Dr. Stritt said the spontaneous passage of asymptomatic stones was largely influenced by a higher number of stones on CT imaging at randomization (P = .001) and a lower total stone volume (P = .001).

Ephrem Olweny, MD, an assistant professor of urology and section chief of endourology at Rush University Medical Center in Chicago, said previous studies have found that the rate of spontaneous passage of kidney stones ranges from 3% to 29%.

“But this secondary analysis of data from a prior multicenter prospective randomized trial offers higher-quality data that will be of value in guiding patient counseling,” Dr. Olweny said.

“Observation should be initially offered to these patients. However, patients should be informed that 52% are likely to develop symptoms, and some may indeed opt for preemptive surgical removal,” he added.

David Schulsinger, MD, an associate professor in the department of urology at Stony Brook (N.Y.) University Hospital, said the incidence of kidney stones has been increasing worldwide, affecting approximately 12% of men and 6% of women. Dehydration and diets high in sodium and calcium are major factors, he said.

Patients with a history of stones have a 50% risk of recurrence in the next 5 years, and an 80% risk in their lifetime, he added.

Dr. Schulsinger said the message from the Swiss study is that urologists can be “comfortable” watching small stones, those averaging 2.4 mm or less in size. “But if a patient has a 7- or  8-mm stone, you might be more inclined to manage that patient a little bit more aggressively.”

Roughly half of patients with stones less than 2 mm will pass it in about 8 days, he said. 

Dr. Olweny noted that the study was a secondary analysis of data from a randomized controlled trial that evaluated the efficacy of thiazides in preventing the recurrence of calcium stones. “The original study was not specifically designed to look at asymptomatic stone passage rates for small renal stones, and therefore, the observed rates may not reflect the most precise estimates,” he said.

Dr. Stritt said his group has not studied the size limit of stones that pass spontaneously without symptoms. “This study could serve to construct recurrence prediction models based on medical history and stone burden on CT imaging. More well-designed research on this topic is urgently needed,” he said. “These results should encourage urologists to counsel patients about the possibility of an active surveillance strategy when smaller kidney stones are present.”

The author and independent commentators have reported no relevant financial relationships.

Interdisciplinary program reduced pediatric pain without pharmacology

Article Type

Tue, 05/09/2023 - 18:08

WASHINGTON – A nonpharmacologic, interdisciplinary program significantly improved chronic pain in children and the quality of life for their families, based on data from 115 individuals.

Up to 40% of children experience chronic pain that affects their physical, psychosocial, and educational functioning, said Jessica Campanile, BA, a medical student at the University of Pennsylvania, Philadelphia, in a presentation at the Pediatric Academic Societies annual meeting.

Although interdisciplinary pediatric pain rehabilitation programs have shown positive outcomes, very few use only nonpharmacologic treatments, said Ms. Campanile. In addition, few studies have explored the effects of a hospital-based program on the patients and their families.

Ms. Campanile and colleagues conducted a retrospective cohort study of participants in an outpatient pain rehabilitation program at the Children’s Hospital of Philadelphia between April 2016 and December 2019. Patients were evaluated by a pediatric rheumatologist, psychologist, and physical and occupational therapists.

Patients engaged in 2-3 hours of physical therapy (PT) and 2-3 hours of occupational therapy (OT) in a 1:1 ratio at least 5 days a week. Physical activities included stepping into and out of a tub, carrying laundry, and desensitizing to allodynia as needed. Participants also received individual and group cognitive-behavior therapy interventions from psychologists, and psychological support during PT and OT sessions if needed. Parents/caregivers were invited to separate individual and group therapy sessions as part of the program. The median age at admission to the program was 15 years, and 79% of the participants were female. Patients participated the program for a median of 17 days, and 87% were outpatients who came to the hospital for the program.

Pain was assessed based on the 0-10 verbal pain intensity scale, energy was assessed on a scale of 0-100, and functional disability was assessed on a scale of 0-60, with higher scores indicating more pain, more energy, and more self-perceived disability, respectively.

Overall, scores on measures of pain, disability, allodynia, and energy improved significantly from baseline to discharge from the program. Verbal pain intensity scores decreased on average from 7 to 5, disability scores decreased from 26 to 9, the proportion of patients reporting allodynia decreased from 86% to 61%, and the energy level score increased from 70 to 77. The trend continued at the first follow-up visit, conducted 2-3 months after discharge from the program. Notably, pain intensity further decreased from a median of 5 at program completion to a median of 2 at the first follow-up, Ms. Campanile said. Improvements in allodynia also were sustained at the first follow-up.

Quality of life measures related to physical, emotional, social, and cognitive function also improved significantly from baseline to completion of the program.

In addition, scores on a quality of life family impact survey improved significantly; in particular, parent health-related quality of life scores (Parent HRQoL) improved from 60 at baseline to 71 at the end of the program on a scale of 0 to 100. The study findings were limited by several factors including the relatively short duration and use of a convenience sample from a retrospective cohort, with data limited to electronic health records, Ms. Campanile said. The study also was not powered to examine differential treatments based on psychiatric conditions, and any psychiatric conditions were based on self-reports.

However, the results support the value of a nonpharmacologic interdisciplinary program as “a robust treatment for youth with chronic idiopathic pain, for both patients and the family unit,” she said.

“This study also supports the need for and benefit of additional counseling for patients and their caregivers prior to and during enrollment in a pain rehabilitation program,” she concluded.
 

 

 

Study supports effectiveness of drug-free pain management

“The management of pain in any age group can be challenging, especially with current concerns for opioid dependence and abuse,” Cathy Haut, DNP, CPNP-AC, CPNP-PC, a pediatric nurse practitioner in Rehoboth Beach, Del., said in an interview.

“Chronic pain affects daily life for all populations, but for children, adolescents, and their families, it can have a long-lasting impact on growth and development, psychosocial and physical well-being,” Dr. Haut said. “Determining and testing nonpharmacologic alternative methods of pain control are extremely important.”

Given the debilitating effects of chronic pain, and the potential side effects and dependence that have been associated with use of pharmacologic modes of pain control, unique and creative solutions have begun to emerge and need further attention and study, she said.

However, “despite published research supporting the use of alternative and complementary approaches to pain control in children and adolescents, nonpharmacologic, collaborative, interprofessional approaches to pain control have not been widely shared in the literature,” she said.

“Barriers to this type of program include first and foremost a potential lack of financial and workforce-related resources,” Dr. Haut said. “Patient and family attendance at frequent health visits, daily or even every other day, may also hinder success, but opportunities for telehealth and family training to learn physical and occupational skills within this type of program may be beginning solutions.”

Additional research should be conducted at multiple children’s hospitals, with a larger number of children and adolescents at varying ages, with pain related to different diagnoses, and with the inclusion of collaborative methodology, said Dr. Haut. “The current study had some limitations, including the small sample size, predominantly female sex, and a short participation time frame utilizing retrospective review. Completing prospective research over a longer time frame can also yield generalizable results applicable to varied populations.”

The study received no outside funding. Ms. Campanile had no financial conflicts to disclose. Dr. Haut had no financial conflicts to disclose, and serves on the editorial advisory board of Pediatric News.

Given the debilitating effects of chronic pain, and the potential side effects and dependence that have been associated with use of pharmacologic modes of pain control, unique and creative solutions have begun to emerge and need further attention and study, she said.

However, “despite published research supporting the use of alternative and complementary approaches to pain control in children and adolescents, nonpharmacologic, collaborative, interprofessional approaches to pain control have not been widely shared in the literature,” she said.

“Barriers to this type of program include first and foremost a potential lack of financial and workforce-related resources,” Dr. Haut said. “Patient and family attendance at frequent health visits, daily or even every other day, may also hinder success, but opportunities for telehealth and family training to learn physical and occupational skills within this type of program may be beginning solutions.”

Additional research should be conducted at multiple children’s hospitals, with a larger number of children and adolescents at varying ages, with pain related to different diagnoses, and with the inclusion of collaborative methodology, said Dr. Haut. “The current study had some limitations, including the small sample size, predominantly female sex, and a short participation time frame utilizing retrospective review. Completing prospective research over a longer time frame can also yield generalizable results applicable to varied populations.”

The study received no outside funding. Ms. Campanile had no financial conflicts to disclose. Dr. Haut had no financial conflicts to disclose, and serves on the editorial advisory board of Pediatric News.

WASHINGTON – A nonpharmacologic, interdisciplinary program significantly improved chronic pain in children and the quality of life for their families, based on data from 115 individuals.

Up to 40% of children experience chronic pain that affects their physical, psychosocial, and educational functioning, said Jessica Campanile, BA, a medical student at the University of Pennsylvania, Philadelphia, in a presentation at the Pediatric Academic Societies annual meeting.

Although interdisciplinary pediatric pain rehabilitation programs have shown positive outcomes, very few use only nonpharmacologic treatments, said Ms. Campanile. In addition, few studies have explored the effects of a hospital-based program on the patients and their families.

Ms. Campanile and colleagues conducted a retrospective cohort study of participants in an outpatient pain rehabilitation program at the Children’s Hospital of Philadelphia between April 2016 and December 2019. Patients were evaluated by a pediatric rheumatologist, psychologist, and physical and occupational therapists.

Patients engaged in 2-3 hours of physical therapy (PT) and 2-3 hours of occupational therapy (OT) in a 1:1 ratio at least 5 days a week. Physical activities included stepping into and out of a tub, carrying laundry, and desensitizing to allodynia as needed. Participants also received individual and group cognitive-behavior therapy interventions from psychologists, and psychological support during PT and OT sessions if needed. Parents/caregivers were invited to separate individual and group therapy sessions as part of the program. The median age at admission to the program was 15 years, and 79% of the participants were female. Patients participated the program for a median of 17 days, and 87% were outpatients who came to the hospital for the program.

Pain was assessed based on the 0-10 verbal pain intensity scale, energy was assessed on a scale of 0-100, and functional disability was assessed on a scale of 0-60, with higher scores indicating more pain, more energy, and more self-perceived disability, respectively.

Overall, scores on measures of pain, disability, allodynia, and energy improved significantly from baseline to discharge from the program. Verbal pain intensity scores decreased on average from 7 to 5, disability scores decreased from 26 to 9, the proportion of patients reporting allodynia decreased from 86% to 61%, and the energy level score increased from 70 to 77. The trend continued at the first follow-up visit, conducted 2-3 months after discharge from the program. Notably, pain intensity further decreased from a median of 5 at program completion to a median of 2 at the first follow-up, Ms. Campanile said. Improvements in allodynia also were sustained at the first follow-up.

Quality of life measures related to physical, emotional, social, and cognitive function also improved significantly from baseline to completion of the program.

In addition, scores on a quality of life family impact survey improved significantly; in particular, parent health-related quality of life scores (Parent HRQoL) improved from 60 at baseline to 71 at the end of the program on a scale of 0 to 100. The study findings were limited by several factors including the relatively short duration and use of a convenience sample from a retrospective cohort, with data limited to electronic health records, Ms. Campanile said. The study also was not powered to examine differential treatments based on psychiatric conditions, and any psychiatric conditions were based on self-reports.

However, the results support the value of a nonpharmacologic interdisciplinary program as “a robust treatment for youth with chronic idiopathic pain, for both patients and the family unit,” she said.

“This study also supports the need for and benefit of additional counseling for patients and their caregivers prior to and during enrollment in a pain rehabilitation program,” she concluded.

Cancer pain declines with cannabis use

Article Type

Fri, 05/05/2023 - 10:15

Adults with cancer experienced significant reductions in pain after taking medicinal cannabis, in a study.

Physician-prescribed cannabis, particularly cannabinoids, has been shown to ease cancer-related pain in adult cancer patients, who often find inadequate pain relief from medications including opioids, Saro Aprikian, MSc, a medical student at the Royal College of Surgeons, Dublin, and colleagues, wrote in their paper.

However, real-world data on the safety and effectiveness of cannabis in the cancer population and the impact on use of other medications are lacking, the researchers said.

In the study, published in BMJ Supportive & Palliative Care, the researchers reviewed data from 358 adults with cancer who were part of a multicenter cannabis registry in Canada between May 2015 and October 2018.

The average age of the patients was 57.6 years, and 48% were men. The top three cancer diagnoses in the study population were genitorurinary, breast, and colorectal.

Pain was the most common reason for obtaining a medical cannabis prescription, cited by 72.4% of patients.

Data were collected at follow-up visits conducted every 3 months over 1 year. Pain was assessed via the Brief Pain Inventory (BPI) and revised Edmonton Symptom Assessment System (ESAS-r) questionnaires and compared to baseline values. Patients rated their pain intensity on a sliding scale of 0 (none) to 10 (worst possible). Pain relief was rated on a scale of 0% (none) to 100% (complete).

Compared to baseline scores, patients showed significant decreases at 3, 6 and 9 months for BPI worst pain (5.5 at baseline, 3.6 for 3, 6, and 9 months) average pain (4.1 at baseline, 2.4, 2.3, and 2.7 for 3, 6, and 9 months, respectively), overall pain severity (2.7 at baseline, 2.3, 2.3, and 2.4 at 3, 6, and 9 months, respectively), and pain interference with daily life (4.3 at baseline, 2.4, 2.2, and 2.4 at 3, 6, and 9 months, respectively; P less than .01 for all four pain measures).

“Pain severity as reported in the ESAS-r decreased significantly at 3-month, 6-month and 9-month follow-ups,” the researchers noted.

In addition, total medication burden based on the medication quantification scale (MQS) and morphine equivalent daily dose (MEDD) were recorded at 3, 6, 9, and 12 months. MQS scores decreased compared to baseline at 3, 6, 9, and 12 months in 10%, 23.5%, 26.2%, and 31.6% of patients, respectively. Also compared with baseline, 11.1%, 31.3%, and 14.3% of patients reported decreases in MEDD scores at 3, 6, and 9 months, respectively.

Overall, products with equal amounts of active ingredients tetrahydrocannabinol (THC) and cannabidiol (CBD) were more effective than were those with a predominance of either THC or CBD, the researchers wrote.

Medical cannabis was well-tolerated; a total of 15 moderate to severe side effects were reported by 11 patients, 13 of which were minor. The most common side effects were sleepiness and fatigue, and five patients discontinued their medical cannabis because of side effects. The two serious side effects reported during the study period – pneumonia and a cardiovascular event – were deemed unlikely related to the patients’ medicinal cannabis use.

The findings were limited by several factors, including the observational design, which prevented conclusions about causality, the researchers noted. Other limitations included the loss of many patients to follow-up and incomplete data on other prescription medications in many cases.

The results support the use of medical cannabis by cancer patients as an adjunct pain relief strategy and a way to potentially reduce the use of other medications such as opioids, the authors concluded.

The study was supported by the Canadian Consortium for the Investigation of Cannabinoids, Collège des Médecins du Québec, and the Canopy Growth Corporation. The researchers had no financial conflicts to disclose.

Head-to-head comparison of migraine meds reveals top options

Article Type
Changed
Fri, 05/05/2023 - 10:23

When it comes to relieving migraine, triptans, ergots, and antiemetics are the most effective classes of medications, a new real-world analysis of data on more than 3 million migraine attacks shows.

The findings “align with results of clinical trials and recommendations from clinical treatment guidelines” and provide insights to complement clinical practice, said study investigator Chia-Chun Chiang, MD, a neurologist with Mayo Clinic, Rochester, Minn.

The findings were presented at the 2023 annual meeting of the American Academy of Neurology.
 

The power of big data

Despite a wide variety of acute migraine medications that are available, large-scale, head-to-head comparisons of treatment effectiveness from real-world patient experience reports are lacking, Dr. Chiang explained.

“To the best of our knowledge, this is the first study that simultaneously compared multiple acute migraine medications using a Big Data analysis approach based on real-world patient-provided data,” she said.

The researchers extracted more than 10 million self-reported migraine attack records from a migraine smartphone app called Migraine Buddy, where users can document whether a treatment was helpful, somewhat helpful, unsure, or unhelpful.

They analyzed 25 acute medications among seven classes: acetaminophen, nonsteroidal anti-inflammatory drugs (NSAIDs), triptans, combination analgesics (acetaminophen/aspirin/caffeine), ergots, antiemetics, and opioids. The newer gepants and ditan medication classes of medications were not included because of the relatively lower numbers of usage when data was extracted (2014-2020).

The researchers employed a two-level nested logistic regression model to analyze the odds of treatment effectiveness of each medication by adjusting concurrent medications and the covariance within the same user.

The final analysis included more than 3.1 million migraine attacks among 278,000 users globally.

Using ibuprofen as the reference, triptans, ergots, and antiemetics had the highest efficacy with mean odds ratios of 4.8, 3.02, and 2.67, respectively, followed by opioids (OR, 2.49), NSAIDs (OR, 1.94), combination analgesics (OR, 1.69), others (OR, 1.49), and acetaminophen (OR, 0.83).

Individual medications with the highest patient-reported effectiveness were eletriptan (Relpax; OR, 6.1), zolmitriptan (Zomig; OR, 5.7) and sumatriptan (Zecuity; OR, 5.2).

This migraine medication comparative effectiveness analysis, based on patient-reported outcomes, “supports and complements the treatment recommendations from national headache societies based on randomized controlled trials and meta-analyses and strongly supports the use of triptans,” Dr. Chiang said.
 

End of trial-and-error?

Commenting on this research, Shaheen Lakhan, MD, PhD, a neurologist and researcher in Boston, said “This is a great study of Big Data in that it shows the power of the smartphone to collect real-world data and smart researchers like at Mayo Clinic to analyze them.”

“The study sheds light on how different therapeutics compare with each other. The next iteration of this line of research, I would hope, would be to determine if particular medications are effective for a particular migraine population, and even down to individuals with migraine,” said Dr. Lakhan, who wasn’t involved in the study.

“Once those models are appropriately built, long gone will be the era of trial-and-error medicine,” Dr. Lakhan added.

The study had no specific funding. Dr. Chiang has served as a consultant for Satsuma. Dr. Lakhan reports no relevant financial relationships.

FDA expands atogepant approval to include chronic migraine

Article Type
Changed
Tue, 05/02/2023 - 11:59

The Food and Drug Administration has approved an expanded indication for atogepant (Qulipta, Abbvie) to include prevention of chronic migraine in adults. The approval makes atogepant the first, and only, oral calcitonin gene-related peptide receptor antagonist approved to prevent migraine across frequencies, including episodic and chronic, the company said in a news release.

The FDA initially approved atogepant in 2021 for the prevention of episodic migraine in adults.

Once-daily atogepant is available in three doses – 10 mg, 30 mg, and 60 mg – for prevention of episodic migraine. However, only the 60-mg dose of medication is indicated for the preventive treatment of chronic migraine.

The expanded indication in chronic migraine is based on positive results of the phase 3 PROGRESS trial, which evaluated atogepant in more than 700 adults with chronic migraine.

The trial met the primary endpoint of statistically significant reduction from baseline in mean monthly migraine days with atogepant compared with placebo across the 12-week treatment period.

Treatment with atogepant also led to statistically significant improvements in all six secondary endpoints, including the proportion of patients that achieved at least a 50% reduction in mean monthly migraine days across 12 weeks and improvements in function and reduction in activity impairment caused by migraine.

The efficacy results are consistent with those in the ADVANCE episodic migraine trial.

The overall safety profile of atogepant is consistent with the episodic migraine patient population, with the most common adverse events including constipation, nausea, and fatigue/sleepiness.

“The FDA approval is an important milestone, providing those most impacted by migraine with a new, safe, and effective treatment option in a convenient, once-daily pill,” Peter McAllister, MD, director of the New England Center for Neurology and Headache, Stamford, Conn., said in the news release.

The data demonstrate that atogepant “helps reduce the burden of migraine by delivering improvements in function, with high response rates and sustained efficacy over 12 weeks. These are critical factors neurologists and headache specialists consider when prescribing a treatment option, particularly for those with chronic migraine,” Dr. McAllister added.

The Food and Drug Administration has approved an expanded indication for atogepant (Qulipta, Abbvie) to include prevention of chronic migraine in adults. The approval makes atogepant the first, and only, oral calcitonin gene-related peptide receptor antagonist approved to prevent migraine across frequencies, including episodic and chronic, the company said in a news release.

The FDA initially approved atogepant in 2021 for the prevention of episodic migraine in adults.

Once-daily atogepant is available in three doses – 10 mg, 30 mg, and 60 mg – for prevention of episodic migraine. However, only the 60-mg dose of medication is indicated for the preventive treatment of chronic migraine.

The expanded indication in chronic migraine is based on positive results of the phase 3 PROGRESS trial, which evaluated atogepant in more than 700 adults with chronic migraine.

The trial met the primary endpoint of statistically significant reduction from baseline in mean monthly migraine days with atogepant compared with placebo across the 12-week treatment period.

Treatment with atogepant also led to statistically significant improvements in all six secondary endpoints, including the proportion of patients that achieved at least a 50% reduction in mean monthly migraine days across 12 weeks and improvements in function and reduction in activity impairment caused by migraine.

The efficacy results are consistent with those in the ADVANCE episodic migraine trial.

The overall safety profile of atogepant is consistent with the episodic migraine patient population, with the most common adverse events including constipation, nausea, and fatigue/sleepiness.

“The FDA approval is an important milestone, providing those most impacted by migraine with a new, safe, and effective treatment option in a convenient, once-daily pill,” Peter McAllister, MD, director of the New England Center for Neurology and Headache, Stamford, Conn., said in the news release.

Musculoskeletal disorders prevalent in orchestra musicians

Article Type
Changed
Fri, 04/28/2023 - 00:29

 – For orchestra musicians, performance is everything. So, it’s no wonder that musculoskeletal disorders – a reality for so many of these professionals – are not openly discussed. Physical pain is often pushed aside, unexpressed, until one day the suffering gets to be too much, the ability to play is impacted, and all the effort to keep things under wraps and under control culminates in burnout.

Anne Maugue was one of the speakers at the French College of General Medicine’s 16th Congress of General Medicine. Ms. Maugue is a postdoctoral researcher at Côte d’Azur University, Nice, France. She also plays flute in the Monte-Carlo Philharmonic Orchestra. Through her presentation to the physicians, she sought to raise awareness about MSDs in professional musicians, as well as the associated psychosocial risk factors. “If caught early enough, this pain can often be successfully treated.”
 

High prevalence

“You’re a violinist in a major symphony orchestra. It’s Sunday night, 8 o’clock, and you’ve just come off the stage. A few minutes ago, you felt a sharp pain in your right arm – a pain that is now, already, overwhelming. The conductor accused you of not being focused, of not concentrating. You know that you have another rehearsal in just a few hours, Monday morning. So, what do you do – other than hope that the pain goes away by then? Where can you turn to get help?”

With this opening scenario, Ms. Maugue was able to immediately orient the attendees to the realities that professional musicians face.

Pain is far from anecdotal. In professional orchestras, its prevalence over 12 months is between 41% and 93%. “An elite athlete has a full training staff they can turn to. An elite musician, on the other hand, usually only has their general practitioner – and that’s assuming the musician even reaches out to get treatment to begin with.

“The fact is that most of the time musicians only care about the pain when it becomes chronic, when it causes discomfort that affects their playing,” said Ms. Maugue.

How, then, does one evaluate this problem? In a Danish study, musicians rated the musculoskeletal problems they had experienced in the preceding 7 days. When the researchers compared those reports with findings from a clinical examination, they found that the examiners were not able to identify which musicians had reported problems. Why? Because a diagnosis does not reflect the severity or the impact, both of which are subjective.

“When faced with pain, the musician’s initial reaction is denial,” said Ms. Maugue. “The pain is often attributed to something other than the physicality of playing their instrument. They then turn to self-care, to colleagues. It’s only much later that they consult a medical professional.”

As a result, the physician is seldom aware of the musician’s psychological distress and has no sense of how long it’s been since the pain first started.
 

Work environment

Carrying around an instrument all the time and maintaining nonergonomic postures for extended periods are just two of the factors that put professional musicians at risk of physical pain. Not to be forgotten, Ms. Maugue added, are the work-related pressures. Musicians are not immune to issues with their work environment. They can feel like they aren’t getting the resources they need, proper recognition from their leaders, or support from their colleagues. In the end, such feelings can engender a sense of unfairness – and that acts as a stressor that can give rise to MSDs.

Evidence of this phenomenon can be found in the results of a study that Ms. Maugue conducted. Out of 440 French orchestra musicians (44% women), 64% said they had experienced MSD-related pain in the preceding 12 months and 61% in the preceding 7 days.

Using industrial and organizational psychology scales of measurement, Ms. Maugue was able to show, through hierarchical regression, that “emotional exhaustion and MSD-related pain occur when the environment in which people work causes them to feel a sense of unfairness.”
 

Early detection

Finally, Ms. Maugue encouraged general practitioners to ask every patient whether he or she plays a musical instrument. If the answer is yes, get an idea about any pain that he or she may have been feeling in the back, neck, and upper extremities so that prompt treatment can be given.

“There are other studies underway that are looking to better characterize instrumental activity and to enable more effective management by sports medicine departments,” said Ms. Maugue. “But back to patients with MSDs. It’s important to understand everything about their playing. Where do they practice? How often do they practice? What’s their posture like when they play? What’s the tempo of the music they’re working on? Because what we see in professional musicians is likely to be seen in amateur musicians as well – particularly in young people who study at a conservatory,” where not much is being done to prevent MSDs.

“If professional musicians are given treatment early on, half of them can be permanently cured,” she concluded. “And then, just like elite athletes, they’ll be able to get right back to playing.”

Spinal cord stimulation may help diabetic neuropathy

Article Type
Changed
Fri, 04/14/2023 - 11:48

Both pain relief and neurological improvements persisted in patients with diabetic neuropathy 2 years after they began receiving treatment with 10 kHz of spinal cord stimulation, according to research that released early, prior to its presentation at the annual meeting of the American Academy of Neurology.

The data represents the longest follow-up available for spinal cord stimulation at a frequency higher than the 60 Hz initially approved for diabetic neuropathy by the Food and Drug Administration, according to lead author Erika A. Petersen, MD, a professor of neurosurgery and the residency program director at the University of Arkansas for Medical Sciences, Little Rock.

“You would expect that somebody who continues to have diabetes for 24 months and has neuropathy would have worse neuropathy after 2 years, and what we’re seeing is that people were stable or better in terms of their nerve function at 2 years,” Dr. Petersen said in an interview. “So that’s really revolutionary.”
 

Encouraging preliminary findings

The findings are “promising and preliminary,” John D. Markman, MD, a professor in neurology and neurosurgery, vice chair for clinical research, and director of the Translational Pain Research Program at the University of Rochester (N.Y.) Medical Center, said in an interview. Dr. Markman, who was not involved in this study, said that, though the results are encouraging, it’s “less clear how much of [the pain improvement] is due to what we would consider to be on-target, pain-relieving benefit from stimulation versus other factors like expectation.” The crossover rate and amount of reduction in pain intensity are promising, but “I think that excitement is weighed against the fact that this is an open-label study.”

An underused treatment

Although spinal cord stimulation has been around since the late 1960s, its use only picked up steam in the 2000s, when it became more frequently used to treat chronic nerve damage related to neuropathic pain syndromes, Dr. Petersen explained. The FDA approved the treatment’s new indication for diabetic neuropathy in 2015, and data from Abbott and Medtronic have shown benefits from spinal cord stimulation at 60 Hz, but some patients are uncomfortable with the vibration or tingling feelings the devices can cause at that frequency.

“They describe creepy crawlies or ants crawling over the feet, or pins and needles, and painful sensitivity,” Dr. Petersen said. “You create a vibration feeling in the same zone where they already have those feelings of buzzing and pain and vibration, and it’s sometimes actually even more uncomfortable and less satisfying to them in terms of relief” with the spinal cord stimulation at 60 Hz, she said, “so there’s a lot of attrition in terms of who will actually use it.”

At 10 kHz, however, “people don’t feel any vibration or tingling associated with it; it just jams the signal of the pain,” she said. The difference between the frequencies is like that between “a lifeguard whistle and a dog whistle.”
 

 

 

Testing high-frequency stimulation

The new findings included the 24-month follow-up data from a randomized controlled trial that assessed the effectiveness of high-frequency spinal cord stimulation for painful diabetic neuropathy. The original 216 participants enrolled in the trial had diabetic neuropathy symptoms for at least 12 months and either could no not tolerate or did not respond to medications. Enrollment criteria also included lower-limb pain intensity of at least 5 on a 0-10 visual analogy scale and hemoglobin A1c of no more than 10%.

For the first 6 months of the trial – before crossover was offered – participants were randomly assigned to receive either 10 kHz of spinal cord stimulation along with conventional medical management or to receive conventional medical management alone. The 6-month data from 187 patients, as reported in April 2021 in JAMA Neurology, revealed that 79% of those receiving spinal cord stimulation experienced at least 50% improved pain relief without worsening of their baseline neurologic deficits, compared with only 5% of those receiving only conventional treatments.

Average pain levels increased 2% in the control participants compared with a decrease of 76% in those with the spinal cord stimulation devices. In addition, 62% of the patients receiving spinal cord stimulation demonstration neurologic improvement in reflexes, strength, movement and sensation, compared with 3% of those in the control group. The study’s findings led the FDA to approve the device using 10 kHz.

At 6 months, 93% of control patients crossed over to receiving spinal cord stimulation while none with the devices opted to stop their spinal cord stimulation. The 12-month data revealed that 85% of those receiving spinal cord stimulation experienced at least 50% pain relief, with the average pain relief at 74%. Patients also reported statistically significant improved quality of life as well as less interference with sleep, mood, and daily activities from pain.

Two years after baseline, patients’ pain relief was maintained with average 80% improvement, and 66% of patients showed neurologic improvement since baseline. Though no patients had devices removed because of ineffectiveness, five patients’ devices were removed because of infection while infections in three other patients resolved.

“Being able to offer something that is not a pharmaceutical, without the side effects, that shows an even longer durability to that response is a really important finding at this point,” Dr. Petersen said.
 

Surgical considerations

Among the estimated 37 million Americans with type 1 or 2 diabetes, approximately one quarter of them experience some level of painful diabetic neuropathy, but medication and other medical management strategies are not always adequate in treating their pain. After a 1-week trial of spinal cord stimulation, the devices are implanted under the skin and rechargeable through the skin for up to 10 years, after which they can be replaced.

An appropriate candidate for spinal cord stimulation would be someone for whom existing non-invasive pain relief options, including medications, are ineffective or intolerable, Dr. Petersen and Dr. Markman both said. An adequate trial of medication is not “one size fits all” and will vary by each patient, added Dr. Markman, who is also interested in whether this study’s participants were able to have a reduction in use of pain relief medications.

“I think there’s a significant number of patients out there who can benefit from this, so I think that’s why it’s promising and exciting,” Dr. Markman said. “I do think it’s important to see if this actually allows them to be on less medication or whether stimulation turns out to be another treatment in addition to their baseline treatments.” The challenge is identifying “which patients are most likely to be benefiting from this and which are most likely to be harmed.”

Aside from infection from implantation, other possible risks include pain at the battery site and, in rare cases, a need for reoperation because of migration of the leads, he said.
 

 

 

Improvement in symptom severity and quality of life

After the wound from the implant has completely healed, Dr. Petersen said patients using the devices do not have any activity restrictions outside of magnetic interference, such as MRIs. “I’ve had people go back-country kayaking, scuba diving, fishing with their grandkids, all sorts of all sorts of things. If patients need to go through a scanner of any kind, they should ask whether it’s safe for pacemakers since these devices are like a “pacemaker for pain.

“I had a patient bring solar chargers with him so that he could recharge his battery in the backwoods while kayaking because that’s the level of improvement in pain that he got – from barely being able to walk down the hall to feeling comfortable being off the grid and active again,” Dr. Petersen said. “Those kinds of improvements in quality of life are massive.”

The study findings may also suggest that spinal cord stimulation can benefit a broader population of patients experiencing neuropathic pain, Dr. Markman said.

“There’s an extraordinary unmet need for treatments for neuropathy, and one important question here is the extent to which diabetic peripheral neuropathy and the response that we’re seeing here is a proxy for a broader effect across many neuropathies that are caused by other conditions other than diabetes,” Dr. Markman said. “There’s a lot of reason to think that this will be helpful not just for diabetes-related neuropathic pain, but for other types of neuropathic pain that have similar clinical presentations or clinical symptom patterns to diabetic peripheral neuropathy.”

The study was funded by Nevro, who manufactures the devices. Dr. Petersen and Dr. Markman both reported consulting with, receiving support from, holding stock options with, and serving on the data safety monitoring boards and advisory boards of numerous pharmaceutical companies.

Among the estimated 37 million Americans with type 1 or 2 diabetes, approximately one quarter of them experience some level of painful diabetic neuropathy, but medication and other medical management strategies are not always adequate in treating their pain. After a 1-week trial of spinal cord stimulation, the devices are implanted under the skin and rechargeable through the skin for up to 10 years, after which they can be replaced.

An appropriate candidate for spinal cord stimulation would be someone for whom existing non-invasive pain relief options, including medications, are ineffective or intolerable, Dr. Petersen and Dr. Markman both said. An adequate trial of medication is not “one size fits all” and will vary by each patient, added Dr. Markman, who is also interested in whether this study’s participants were able to have a reduction in use of pain relief medications.

“I think there’s a significant number of patients out there who can benefit from this, so I think that’s why it’s promising and exciting,” Dr. Markman said. “I do think it’s important to see if this actually allows them to be on less medication or whether stimulation turns out to be another treatment in addition to their baseline treatments.” The challenge is identifying “which patients are most likely to be benefiting from this and which are most likely to be harmed.”

Aside from infection from implantation, other possible risks include pain at the battery site and, in rare cases, a need for reoperation because of migration of the leads, he said.
 

 

 

Improvement in symptom severity and quality of life

After the wound from the implant has completely healed, Dr. Petersen said patients using the devices do not have any activity restrictions outside of magnetic interference, such as MRIs. “I’ve had people go back-country kayaking, scuba diving, fishing with their grandkids, all sorts of all sorts of things. If patients need to go through a scanner of any kind, they should ask whether it’s safe for pacemakers since these devices are like a “pacemaker for pain.

“I had a patient bring solar chargers with him so that he could recharge his battery in the backwoods while kayaking because that’s the level of improvement in pain that he got – from barely being able to walk down the hall to feeling comfortable being off the grid and active again,” Dr. Petersen said. “Those kinds of improvements in quality of life are massive.”

The study findings may also suggest that spinal cord stimulation can benefit a broader population of patients experiencing neuropathic pain, Dr. Markman said.

“There’s an extraordinary unmet need for treatments for neuropathy, and one important question here is the extent to which diabetic peripheral neuropathy and the response that we’re seeing here is a proxy for a broader effect across many neuropathies that are caused by other conditions other than diabetes,” Dr. Markman said. “There’s a lot of reason to think that this will be helpful not just for diabetes-related neuropathic pain, but for other types of neuropathic pain that have similar clinical presentations or clinical symptom patterns to diabetic peripheral neuropathy.”

The study was funded by Nevro, who manufactures the devices. Dr. Petersen and Dr. Markman both reported consulting with, receiving support from, holding stock options with, and serving on the data safety monitoring boards and advisory boards of numerous pharmaceutical companies.

Both pain relief and neurological improvements persisted in patients with diabetic neuropathy 2 years after they began receiving treatment with 10 kHz of spinal cord stimulation, according to research that released early, prior to its presentation at the annual meeting of the American Academy of Neurology.

The data represents the longest follow-up available for spinal cord stimulation at a frequency higher than the 60 Hz initially approved for diabetic neuropathy by the Food and Drug Administration, according to lead author Erika A. Petersen, MD, a professor of neurosurgery and the residency program director at the University of Arkansas for Medical Sciences, Little Rock.

“You would expect that somebody who continues to have diabetes for 24 months and has neuropathy would have worse neuropathy after 2 years, and what we’re seeing is that people were stable or better in terms of their nerve function at 2 years,” Dr. Petersen said in an interview. “So that’s really revolutionary.”
 

Encouraging preliminary findings

The findings are “promising and preliminary,” John D. Markman, MD, a professor in neurology and neurosurgery, vice chair for clinical research, and director of the Translational Pain Research Program at the University of Rochester (N.Y.) Medical Center, said in an interview. Dr. Markman, who was not involved in this study, said that, though the results are encouraging, it’s “less clear how much of [the pain improvement] is due to what we would consider to be on-target, pain-relieving benefit from stimulation versus other factors like expectation.” The crossover rate and amount of reduction in pain intensity are promising, but “I think that excitement is weighed against the fact that this is an open-label study.”

An underused treatment

Although spinal cord stimulation has been around since the late 1960s, its use only picked up steam in the 2000s, when it became more frequently used to treat chronic nerve damage related to neuropathic pain syndromes, Dr. Petersen explained. The FDA approved the treatment’s new indication for diabetic neuropathy in 2015, and data from Abbott and Medtronic have shown benefits from spinal cord stimulation at 60 Hz, but some patients are uncomfortable with the vibration or tingling feelings the devices can cause at that frequency.

“They describe creepy crawlies or ants crawling over the feet, or pins and needles, and painful sensitivity,” Dr. Petersen said. “You create a vibration feeling in the same zone where they already have those feelings of buzzing and pain and vibration, and it’s sometimes actually even more uncomfortable and less satisfying to them in terms of relief” with the spinal cord stimulation at 60 Hz, she said, “so there’s a lot of attrition in terms of who will actually use it.”

At 10 kHz, however, “people don’t feel any vibration or tingling associated with it; it just jams the signal of the pain,” she said. The difference between the frequencies is like that between “a lifeguard whistle and a dog whistle.”
 

 

 

Testing high-frequency stimulation

The new findings included the 24-month follow-up data from a randomized controlled trial that assessed the effectiveness of high-frequency spinal cord stimulation for painful diabetic neuropathy. The original 216 participants enrolled in the trial had diabetic neuropathy symptoms for at least 12 months and either could no not tolerate or did not respond to medications. Enrollment criteria also included lower-limb pain intensity of at least 5 on a 0-10 visual analogy scale and hemoglobin A1c of no more than 10%.

For the first 6 months of the trial – before crossover was offered – participants were randomly assigned to receive either 10 kHz of spinal cord stimulation along with conventional medical management or to receive conventional medical management alone. The 6-month data from 187 patients, as reported in April 2021 in JAMA Neurology, revealed that 79% of those receiving spinal cord stimulation experienced at least 50% improved pain relief without worsening of their baseline neurologic deficits, compared with only 5% of those receiving only conventional treatments.

Average pain levels increased 2% in the control participants compared with a decrease of 76% in those with the spinal cord stimulation devices. In addition, 62% of the patients receiving spinal cord stimulation demonstration neurologic improvement in reflexes, strength, movement and sensation, compared with 3% of those in the control group. The study’s findings led the FDA to approve the device using 10 kHz.

At 6 months, 93% of control patients crossed over to receiving spinal cord stimulation while none with the devices opted to stop their spinal cord stimulation. The 12-month data revealed that 85% of those receiving spinal cord stimulation experienced at least 50% pain relief, with the average pain relief at 74%. Patients also reported statistically significant improved quality of life as well as less interference with sleep, mood, and daily activities from pain.

Two years after baseline, patients’ pain relief was maintained with average 80% improvement, and 66% of patients showed neurologic improvement since baseline. Though no patients had devices removed because of ineffectiveness, five patients’ devices were removed because of infection while infections in three other patients resolved.

“Being able to offer something that is not a pharmaceutical, without the side effects, that shows an even longer durability to that response is a really important finding at this point,” Dr. Petersen said.

Battlefield Acupuncture vs Ketorolac for Treating Pain in the Emergency Department

Article Type
Changed
Wed, 04/12/2023 - 09:05

Acute pain is a primary symptom for many patients who present to the emergency department (ED). The ED team is challenged with relieving pain while limiting harm from medications.1 A 2017 National Health Interview Survey showed that compared with nonveterans, more veterans reported pain in the previous 3 months, and the rate of severe pain was 40% higher in the veteran group especially among those who served during the era of wars in Afghanistan and Iraq.2

The American College of Emergency Physicians guidelines pain management guidelines recommend patient-centered shared decision making that includes patient education about treatment goals and expectations, and short- and long-term risks, as well as a preference toward pharmacologic treatment with nonopioid analgesics except for patients with severe pain or pain refractory to other drug and treatment modalities.3 There is a lack of evidence regarding superior efficacy of either opioid or nonopioid analgesics; therefore, the use of nonopioid analgesics, such as oral or topical nonsteroidal anti-inflammatory drugs (NSAIDs) or central analgesics, such as acetaminophen, is preferred for treating acute pain to mitigate adverse effects (AEs) and risks associated with opioid use.1,3,4 The US Department of Veterans Affairs (VA) and Department of Defense (DoD) guideline on managing opioid therapy for chronic pain, updated in 2017 and 2022, similarly recommends alternatives to opioids for mild-to-moderate acute pain and encourages multimodal pain care.5 However, use of other pharmacologic treatments, such as NSAIDs, is limited by AE profiles, patient contraindications, and severity of acute pain etiologies. There is a need for the expanded use of nonpharmacologic treatments for addressing pain in the veteran population.

The American College of Emergency Physicians guidelines recommend nonpharmacologic modalities, such as applying heat or cold, physical therapy, cognitive behavioral therapy, and acupuncture.3 A 2014 study reported that 37% to 46% of active duty and reserve military personnel use complementary and alternative medicine (CAM) for a variety of ailments, and there is increasing interest in the use of CAM as adjuncts to traditional therapies.6 According to one study, some CAM therapies are used significantly more by military personnel than used by civilians.7 However, the percentage of the veteran population using acupuncture in this study was small, and more information is needed to assess its use.

Auricular acupuncture originated in traditional Chinese medicine.8 Contemporary auricular acupuncture experts view this modality as a self-contained microsystem mapping portions of the ear to specific parts of the body and internal organs. The analgesic effects may be mediated through the central nervous system by local release of endorphins through nerve fiber activation and neurotransmitters—including serotonin, dopamine, and norepinephrine—leading to pre- and postsynaptic suppression of pain transmission.

Battlefield acupuncture (BFA) uses 5 set points anatomically located on each ear.9 Practitioners use small semipermanent, dartlike acupuncture needles. Patients could experience pain relief in a few minutes, which can last minutes, hours, days, weeks, or months depending on the pathology of the pain. This procedure developed in 2001 has been studied for different pain types and has shown benefit when used for postsurgical pain, chronic spinal cord injury−related neuropathic pain, and general chronic pain, as well as for other indications, such as insomnia, depression, and weight loss.8,10-13 In 2018, a randomized controlled trial compared postintervention numeric rating scale (NRS) pain scores in patients presenting to the ED with acute or acute-on-chronic lower back pain who received BFA as an adjunct to standard care vs standard care alone.14 Patients receiving BFA as an adjunct to standard care were found to have mean postintervention pain scores 1.7 points lower than those receiving standard care alone. This study demonstrated that BFA was feasible and well tolerated for lower back pain in the ED as an adjunct to standard care. The study was limited by the adjunct use of BFA rather than as monotherapy and by the practitioners’ discretion regarding standard care, which was not defined by the study’s authors.

 

 


The Jesse Brown Veterans Affairs Medical Center (JBVAMC) in Chicago, Illinois, offers several CAM modalities, such as exercise/movement therapy, chiropractic, art/music therapy, and relaxation workshops, which are widely used by veterans. Recent evidence suggests BFA could reduce pain scores as an adjunct or an alternative to pharmacologic therapy. We are interested in how CAM therapies, such as BFA, can help avoid AEs associated with opioid or NSAID therapy.

At the JBVAMC ED, ketorolac 15 mg is the preferred first-line treatment of acute, noncancer pain, based on the results of previous studies. In 2018 BFA was offered first to veterans presenting with acute or acute-on-chronic pain to the ED; however, its effectiveness for pain reduction vs ketorolac has not been evaluated in this patient population. Limited literature is available on BFA and its use in the ED. To our knowledge, this was the first observational study assessing the difference between a single session of BFA vs a single dose of ketorolac in treating noncancer acute or acute-on-chronic pain in the ED.

Methods

This study was a retrospective chart review of patients who presented to the JBVAMC ED with acute pain or acute-on-chronic pain, who received ketorolac or BFA. The study population was generated from a list of all IV and intramuscular (IM) ketorolac unit dose orders verified from June 1, 2018, through August 30, 2019, and a list of all BFA procedure notes signed from June 1, 2018, through August 30, 2019. Patients were included in the study if they had documented administration of IV or IM ketorolac or BFA between June 1, 2018, and August 30, 2019. Patients who received ketorolac doses other than 15 mg, the intervention was administered outside of the ED, received adjunct treatment in addition to the treatment intervention in the ED, had no baseline NRS pain score documented before the intervention, had an NRS pain score of < 4, had no postintervention NRS pain score documented within 6 hours, had a treatment indication other than pain, or had active cancer were excluded. As in previous JBVAMC studies, we used NRS pain score cutoffs (mild, moderate, severe, and very severe) based on Woo and colleagues’ meta-analysis and excluded scores < 4.15

Endpoints

The primary endpoint was the mean difference in NRS pain score before and after the intervention, determined by comparing the NRS pain score documented at triage to the ED with the first documented NRS pain score at least 30 minutes to 6 hours after treatment administration. The secondary endpoints included the number of patients prescribed pain medication at discharge, the number of patients who were discharged with no medications, and the number of patients admitted to the hospital. The safety endpoint included any AEs of the intervention. Subgroup analyses were performed comparing the mean difference in NRS pain score among subgroups classified by severity of baseline NRS pain score and pain location.

Statistical Analysis

Baseline characteristics and endpoints were analyzed using descriptive statistics. Categorical data were analyzed using Fisher exact test and z test for proportions, and continuous data were compared using t test and paired t test. An 80% power calculation determined that 84 patients per group were needed to detect a statistically significant difference in pain score reduction of 1.3 at a type-1 error rate of 0.05. The sample size was based on a calculation performed in a previously published study that compared IV ketorolac at 3 single-dose regimens for treating acute pain in the ED.16 The 1.3 pain score reduction is considered the minimum clinically significant difference in pain that could be detected with the NRS.17

 

 

Results

Sixty-one patients received BFA during the study period: 31 were excluded (26 received adjunct treatment in the ED, 2 had active cancer documented, 2 had an indication other than pain, and 1 received BFA outside of the ED), leaving 30 patients in the BFA cohort. During the study period, 1299 patients received ketorolac. These patients were selected using a random number generator and then screened to determine inclusion or exclusion in the study. We continued to randomly select patients for the ketorolac group until we had a similar number in each treatment group. Of these 148 patients who were randomly selected to be reviewed, 116 were excluded: 48 received adjunct treatment in the ED, 24 had no postintervention NRS pain score documented within 6 hours, 18 received ketorolac doses other than 15 mg, 12 received ketorolac outside the ED, 9 had no baseline NRS pain score documented, 3 presented with a NRS pain score of ≤ 3, and 2 had active cancer documented. The ketorolac cohort comprised 31 patients.

Baseline characteristics were similar between the 2 groups except for the average baseline NRS pain score, which was statistically significantly higher in the BFA vs ketorolac group (8.7 vs 7.7, respectively; P = .02). The mean age was 51 years in the BFA group and 48 years in the ketorolac group. Most patients in each cohort were male: 80% in the BFA group and 71% in the ketorolac group. The most common types of pain documented as the chief ED presentation included back, lower extremity, and head.

Table 1
Ten patients in the BFA group and 3 in the ketorolac group presented with lower extremity pain (P = .02) (Table 1).

Endpoints

The mean difference in NRS pain score was 3.9 for the BFA group and 5.1 for the ketorolac group. Both were clinically and statistically significant reductions (P = .03 and P < .01), but the difference between the intervention groups in NRS score reduction was not statistically significant (P = .07).

For the secondary endpoint of outpatient prescriptions written at discharge, there was no significant difference between the groups except for oral NSAIDs, which were more likely to be prescribed to patients who received ketorolac (P = .01).

Table 2
Patients who received BFA were more likely to receive oral muscle relaxants or topical analgesics, but the difference between the groups was not statistically significant (Table 2). There was no difference in the number of patients who received no prescriptions at ED discharge. Patients who received ketorolac were more likely to be admitted to the hospital (P = .049) (Table 3).
table 3
 No AEs were observed in either treatment group during the study.

Subgroup Analysis

An analysis was performed for subgroups classified by baseline NRS pain score (mild: 4; moderate, 5 - 6; severe, 7 - 9; and very severe, 10). Data for mild pain was limited because a small number of patients received interventions. For moderate pain, the mean difference in NRS pain score for BFA and ketorolac was 3.5 and 3.8, respectively; for severe pain, 3.4 and 5.3; and for very severe pain, 4.6 and 6.4. There was a larger difference in the preintervention and postintervention NRS pain scores within severe pain and very severe pain groups.

The mean difference in NRS pain score reduction between the intervention groups was not statistically significant for any subgroup (Figure).
table 4
A subgroup analysis also was performed comparing pain locations, although no statistically significant difference was found among the subgroups (Table 4).

Discussion

Both interventions resulted in a significant reduction in the mean NRS pain score of about 4 to 5 points within their group, and BFA resulted in a similar NRS pain score reduction compared with ketorolac 15 mg. Because the baseline NRS pain scores were significantly different between the BFA and ketorolac groups, a subgroup analysis revealed that BFA reduced mean NRS pain score in patients with severe and very severe pain but appears to be less beneficial for moderate pain, unlike the ketorolac results that showed a large reduction in all pain groups except for the small sample of patients with mild pain.

 

 

In this study, more patients in the BFA group presented to the ED with lower extremity pain, such as gout or neuropathy, compared with the ketorolac group; however, BFA did not result in a significantly different pain score reduction in this subgroup compared with ketorolac. Patients receiving BFA were more likely to receive topical analgesics or muscle relaxants at discharge; whereas those receiving ketorolac were significantly more likely to receive oral NSAIDs. Patients in this study also were more likely to be admitted to the hospital if they received ketorolac; however, for these patients, pain was secondary to their chief presentation, and the admitting physician’s familiarity with ketorolac might have been the reason for choosing this intervention. Reasons for the admissions were surgical observation, psychiatric stabilization, kidney/gallstones, rule out of acute coronary syndrome, pneumonia, and proctitis in the ketorolac group, and suicidal ideations in the BFA group.

Limitations

As a limited number of patients received BFA at JBVAMC, the study was not sufficiently powered to detect a difference in the primary outcome. Because BFA required a consultation to be entered in the electronic health record, in addition to time needed to perform the procedure, practitioners might have preferred IV/IM ketorolac during busy times in the ED, potentially leading to underrepresentation in the BFA group. Prescribing preferences might have differed among the rotating physicians, timing of the documentation of the NRS pain score could have differed based on the treatment intervention, and the investigators were unable to control or accurately assess whether patients had taken an analgesic medication before presenting to the ED. Because pain and the treating physician are subjective, patients who reported a higher baseline pain severity might have been more likely to be discharged with topical analgesics or muscle relaxants. One way to correct for this subjectivity would be to conduct a larger prospective trial with a single treating physician. Finally, ED encounters in this study were short, and there was no follow-up permitting identification of AEs.

Conclusions

NRS pain score reduction with BFA did not differ compared with ketorolac 15 mg for treating acute and acute-on-chronic pain in the ED. Although this study was underpowered, these results add to the limited existing literature, suggesting that both interventions could result in clinically significant pain score reductions for patients presenting to the ED with severe and very severe pain, making BFA a viable nonpharmacologic option. Future studies could include investigating the benefit of BFA in the veteran population by studying larger samples in the ED, surveying patients after their interventions to identify rates AEs, and exploring the use of BFA for chronic pain in the outpatient setting.

Acute pain is a primary symptom for many patients who present to the emergency department (ED). The ED team is challenged with relieving pain while limiting harm from medications.1 A 2017 National Health Interview Survey showed that compared with nonveterans, more veterans reported pain in the previous 3 months, and the rate of severe pain was 40% higher in the veteran group especially among those who served during the era of wars in Afghanistan and Iraq.2

The American College of Emergency Physicians guidelines pain management guidelines recommend patient-centered shared decision making that includes patient education about treatment goals and expectations, and short- and long-term risks, as well as a preference toward pharmacologic treatment with nonopioid analgesics except for patients with severe pain or pain refractory to other drug and treatment modalities.3 There is a lack of evidence regarding superior efficacy of either opioid or nonopioid analgesics; therefore, the use of nonopioid analgesics, such as oral or topical nonsteroidal anti-inflammatory drugs (NSAIDs) or central analgesics, such as acetaminophen, is preferred for treating acute pain to mitigate adverse effects (AEs) and risks associated with opioid use.1,3,4 The US Department of Veterans Affairs (VA) and Department of Defense (DoD) guideline on managing opioid therapy for chronic pain, updated in 2017 and 2022, similarly recommends alternatives to opioids for mild-to-moderate acute pain and encourages multimodal pain care.5 However, use of other pharmacologic treatments, such as NSAIDs, is limited by AE profiles, patient contraindications, and severity of acute pain etiologies. There is a need for the expanded use of nonpharmacologic treatments for addressing pain in the veteran population.

The American College of Emergency Physicians guidelines recommend nonpharmacologic modalities, such as applying heat or cold, physical therapy, cognitive behavioral therapy, and acupuncture.3 A 2014 study reported that 37% to 46% of active duty and reserve military personnel use complementary and alternative medicine (CAM) for a variety of ailments, and there is increasing interest in the use of CAM as adjuncts to traditional therapies.6 According to one study, some CAM therapies are used significantly more by military personnel than used by civilians.7 However, the percentage of the veteran population using acupuncture in this study was small, and more information is needed to assess its use.

Auricular acupuncture originated in traditional Chinese medicine.8 Contemporary auricular acupuncture experts view this modality as a self-contained microsystem mapping portions of the ear to specific parts of the body and internal organs. The analgesic effects may be mediated through the central nervous system by local release of endorphins through nerve fiber activation and neurotransmitters—including serotonin, dopamine, and norepinephrine—leading to pre- and postsynaptic suppression of pain transmission.

Battlefield acupuncture (BFA) uses 5 set points anatomically located on each ear.9 Practitioners use small semipermanent, dartlike acupuncture needles. Patients could experience pain relief in a few minutes, which can last minutes, hours, days, weeks, or months depending on the pathology of the pain. This procedure developed in 2001 has been studied for different pain types and has shown benefit when used for postsurgical pain, chronic spinal cord injury−related neuropathic pain, and general chronic pain, as well as for other indications, such as insomnia, depression, and weight loss.8,10-13 In 2018, a randomized controlled trial compared postintervention numeric rating scale (NRS) pain scores in patients presenting to the ED with acute or acute-on-chronic lower back pain who received BFA as an adjunct to standard care vs standard care alone.14 Patients receiving BFA as an adjunct to standard care were found to have mean postintervention pain scores 1.7 points lower than those receiving standard care alone. This study demonstrated that BFA was feasible and well tolerated for lower back pain in the ED as an adjunct to standard care. The study was limited by the adjunct use of BFA rather than as monotherapy and by the practitioners’ discretion regarding standard care, which was not defined by the study’s authors.

 

 


The Jesse Brown Veterans Affairs Medical Center (JBVAMC) in Chicago, Illinois, offers several CAM modalities, such as exercise/movement therapy, chiropractic, art/music therapy, and relaxation workshops, which are widely used by veterans. Recent evidence suggests BFA could reduce pain scores as an adjunct or an alternative to pharmacologic therapy. We are interested in how CAM therapies, such as BFA, can help avoid AEs associated with opioid or NSAID therapy.

At the JBVAMC ED, ketorolac 15 mg is the preferred first-line treatment of acute, noncancer pain, based on the results of previous studies. In 2018 BFA was offered first to veterans presenting with acute or acute-on-chronic pain to the ED; however, its effectiveness for pain reduction vs ketorolac has not been evaluated in this patient population. Limited literature is available on BFA and its use in the ED. To our knowledge, this was the first observational study assessing the difference between a single session of BFA vs a single dose of ketorolac in treating noncancer acute or acute-on-chronic pain in the ED.

Methods

This study was a retrospective chart review of patients who presented to the JBVAMC ED with acute pain or acute-on-chronic pain, who received ketorolac or BFA. The study population was generated from a list of all IV and intramuscular (IM) ketorolac unit dose orders verified from June 1, 2018, through August 30, 2019, and a list of all BFA procedure notes signed from June 1, 2018, through August 30, 2019. Patients were included in the study if they had documented administration of IV or IM ketorolac or BFA between June 1, 2018, and August 30, 2019. Patients who received ketorolac doses other than 15 mg, the intervention was administered outside of the ED, received adjunct treatment in addition to the treatment intervention in the ED, had no baseline NRS pain score documented before the intervention, had an NRS pain score of < 4, had no postintervention NRS pain score documented within 6 hours, had a treatment indication other than pain, or had active cancer were excluded. As in previous JBVAMC studies, we used NRS pain score cutoffs (mild, moderate, severe, and very severe) based on Woo and colleagues’ meta-analysis and excluded scores < 4.15

Endpoints

The primary endpoint was the mean difference in NRS pain score before and after the intervention, determined by comparing the NRS pain score documented at triage to the ED with the first documented NRS pain score at least 30 minutes to 6 hours after treatment administration. The secondary endpoints included the number of patients prescribed pain medication at discharge, the number of patients who were discharged with no medications, and the number of patients admitted to the hospital. The safety endpoint included any AEs of the intervention. Subgroup analyses were performed comparing the mean difference in NRS pain score among subgroups classified by severity of baseline NRS pain score and pain location.

Statistical Analysis

Baseline characteristics and endpoints were analyzed using descriptive statistics. Categorical data were analyzed using Fisher exact test and z test for proportions, and continuous data were compared using t test and paired t test. An 80% power calculation determined that 84 patients per group were needed to detect a statistically significant difference in pain score reduction of 1.3 at a type-1 error rate of 0.05. The sample size was based on a calculation performed in a previously published study that compared IV ketorolac at 3 single-dose regimens for treating acute pain in the ED.16 The 1.3 pain score reduction is considered the minimum clinically significant difference in pain that could be detected with the NRS.17

 

 

Results

Sixty-one patients received BFA during the study period: 31 were excluded (26 received adjunct treatment in the ED, 2 had active cancer documented, 2 had an indication other than pain, and 1 received BFA outside of the ED), leaving 30 patients in the BFA cohort. During the study period, 1299 patients received ketorolac. These patients were selected using a random number generator and then screened to determine inclusion or exclusion in the study. We continued to randomly select patients for the ketorolac group until we had a similar number in each treatment group. Of these 148 patients who were randomly selected to be reviewed, 116 were excluded: 48 received adjunct treatment in the ED, 24 had no postintervention NRS pain score documented within 6 hours, 18 received ketorolac doses other than 15 mg, 12 received ketorolac outside the ED, 9 had no baseline NRS pain score documented, 3 presented with a NRS pain score of ≤ 3, and 2 had active cancer documented. The ketorolac cohort comprised 31 patients.

Baseline characteristics were similar between the 2 groups except for the average baseline NRS pain score, which was statistically significantly higher in the BFA vs ketorolac group (8.7 vs 7.7, respectively; P = .02). The mean age was 51 years in the BFA group and 48 years in the ketorolac group. Most patients in each cohort were male: 80% in the BFA group and 71% in the ketorolac group. The most common types of pain documented as the chief ED presentation included back, lower extremity, and head.

Table 1
Ten patients in the BFA group and 3 in the ketorolac group presented with lower extremity pain (P = .02) (Table 1).

Endpoints

The mean difference in NRS pain score was 3.9 for the BFA group and 5.1 for the ketorolac group. Both were clinically and statistically significant reductions (P = .03 and P < .01), but the difference between the intervention groups in NRS score reduction was not statistically significant (P = .07).

For the secondary endpoint of outpatient prescriptions written at discharge, there was no significant difference between the groups except for oral NSAIDs, which were more likely to be prescribed to patients who received ketorolac (P = .01).

Table 2
Patients who received BFA were more likely to receive oral muscle relaxants or topical analgesics, but the difference between the groups was not statistically significant (Table 2). There was no difference in the number of patients who received no prescriptions at ED discharge. Patients who received ketorolac were more likely to be admitted to the hospital (P = .049) (Table 3).
table 3
 No AEs were observed in either treatment group during the study.

Subgroup Analysis

An analysis was performed for subgroups classified by baseline NRS pain score (mild: 4; moderate, 5 - 6; severe, 7 - 9; and very severe, 10). Data for mild pain was limited because a small number of patients received interventions. For moderate pain, the mean difference in NRS pain score for BFA and ketorolac was 3.5 and 3.8, respectively; for severe pain, 3.4 and 5.3; and for very severe pain, 4.6 and 6.4. There was a larger difference in the preintervention and postintervention NRS pain scores within severe pain and very severe pain groups.

The mean difference in NRS pain score reduction between the intervention groups was not statistically significant for any subgroup (Figure).
table 4
A subgroup analysis also was performed comparing pain locations, although no statistically significant difference was found among the subgroups (Table 4).

Discussion

Both interventions resulted in a significant reduction in the mean NRS pain score of about 4 to 5 points within their group, and BFA resulted in a similar NRS pain score reduction compared with ketorolac 15 mg. Because the baseline NRS pain scores were significantly different between the BFA and ketorolac groups, a subgroup analysis revealed that BFA reduced mean NRS pain score in patients with severe and very severe pain but appears to be less beneficial for moderate pain, unlike the ketorolac results that showed a large reduction in all pain groups except for the small sample of patients with mild pain.

 

 

In this study, more patients in the BFA group presented to the ED with lower extremity pain, such as gout or neuropathy, compared with the ketorolac group; however, BFA did not result in a significantly different pain score reduction in this subgroup compared with ketorolac. Patients receiving BFA were more likely to receive topical analgesics or muscle relaxants at discharge; whereas those receiving ketorolac were significantly more likely to receive oral NSAIDs. Patients in this study also were more likely to be admitted to the hospital if they received ketorolac; however, for these patients, pain was secondary to their chief presentation, and the admitting physician’s familiarity with ketorolac might have been the reason for choosing this intervention. Reasons for the admissions were surgical observation, psychiatric stabilization, kidney/gallstones, rule out of acute coronary syndrome, pneumonia, and proctitis in the ketorolac group, and suicidal ideations in the BFA group.

Limitations

As a limited number of patients received BFA at JBVAMC, the study was not sufficiently powered to detect a difference in the primary outcome. Because BFA required a consultation to be entered in the electronic health record, in addition to time needed to perform the procedure, practitioners might have preferred IV/IM ketorolac during busy times in the ED, potentially leading to underrepresentation in the BFA group. Prescribing preferences might have differed among the rotating physicians, timing of the documentation of the NRS pain score could have differed based on the treatment intervention, and the investigators were unable to control or accurately assess whether patients had taken an analgesic medication before presenting to the ED. Because pain and the treating physician are subjective, patients who reported a higher baseline pain severity might have been more likely to be discharged with topical analgesics or muscle relaxants. One way to correct for this subjectivity would be to conduct a larger prospective trial with a single treating physician. Finally, ED encounters in this study were short, and there was no follow-up permitting identification of AEs.

Conclusions

NRS pain score reduction with BFA did not differ compared with ketorolac 15 mg for treating acute and acute-on-chronic pain in the ED. Although this study was underpowered, these results add to the limited existing literature, suggesting that both interventions could result in clinically significant pain score reductions for patients presenting to the ED with severe and very severe pain, making BFA a viable nonpharmacologic option. Future studies could include investigating the benefit of BFA in the veteran population by studying larger samples in the ED, surveying patients after their interventions to identify rates AEs, and exploring the use of BFA for chronic pain in the outpatient setting.

At the JBVAMC ED, ketorolac 15 mg is the preferred first-line treatment of acute, noncancer pain, based on the results of previous studies. In 2018 BFA was offered first to veterans presenting with acute or acute-on-chronic pain to the ED; however, its effectiveness for pain reduction vs ketorolac has not been evaluated in this patient population. Limited literature is available on BFA and its use in the ED. To our knowledge, this was the first observational study assessing the difference between a single session of BFA vs a single dose of ketorolac in treating noncancer acute or acute-on-chronic pain in the ED.

Methods

This study was a retrospective chart review of patients who presented to the JBVAMC ED with acute pain or acute-on-chronic pain, who received ketorolac or BFA. The study population was generated from a list of all IV and intramuscular (IM) ketorolac unit dose orders verified from June 1, 2018, through August 30, 2019, and a list of all BFA procedure notes signed from June 1, 2018, through August 30, 2019. Patients were included in the study if they had documented administration of IV or IM ketorolac or BFA between June 1, 2018, and August 30, 2019. Patients who received ketorolac doses other than 15 mg, the intervention was administered outside of the ED, received adjunct treatment in addition to the treatment intervention in the ED, had no baseline NRS pain score documented before the intervention, had an NRS pain score of < 4, had no postintervention NRS pain score documented within 6 hours, had a treatment indication other than pain, or had active cancer were excluded. As in previous JBVAMC studies, we used NRS pain score cutoffs (mild, moderate, severe, and very severe) based on Woo and colleagues’ meta-analysis and excluded scores < 4.15

Results

Sixty-one patients received BFA during the study period: 31 were excluded (26 received adjunct treatment in the ED, 2 had active cancer documented, 2 had an indication other than pain, and 1 received BFA outside of the ED), leaving 30 patients in the BFA cohort. During the study period, 1299 patients received ketorolac. These patients were selected using a random number generator and then screened to determine inclusion or exclusion in the study. We continued to randomly select patients for the ketorolac group until we had a similar number in each treatment group. Of these 148 patients who were randomly selected to be reviewed, 116 were excluded: 48 received adjunct treatment in the ED, 24 had no postintervention NRS pain score documented within 6 hours, 18 received ketorolac doses other than 15 mg, 12 received ketorolac outside the ED, 9 had no baseline NRS pain score documented, 3 presented with a NRS pain score of ≤ 3, and 2 had active cancer documented. The ketorolac cohort comprised 31 patients.

Baseline characteristics were similar between the 2 groups except for the average baseline NRS pain score, which was statistically significantly higher in the BFA vs ketorolac group (8.7 vs 7.7, respectively; P = .02). The mean age was 51 years in the BFA group and 48 years in the ketorolac group. Most patients in each cohort were male: 80% in the BFA group and 71% in the ketorolac group. The most common types of pain documented as the chief ED presentation included back, lower extremity, and head.

Table 1
Ten patients in the BFA group and 3 in the ketorolac group presented with lower extremity pain (P = .02) (Table 1).

Endpoints

The mean difference in NRS pain score was 3.9 for the BFA group and 5.1 for the ketorolac group. Both were clinically and statistically significant reductions (P = .03 and P < .01), but the difference between the intervention groups in NRS score reduction was not statistically significant (P = .07).

For the secondary endpoint of outpatient prescriptions written at discharge, there was no significant difference between the groups except for oral NSAIDs, which were more likely to be prescribed to patients who received ketorolac (P = .01).

Patients who received BFA were more likely to receive oral muscle relaxants or topical analgesics, but the difference between the groups was not statistically significant (Table 2).

Subgroup Analysis

An analysis was performed for subgroups classified by baseline NRS pain score (mild: 4; moderate, 5 - 6; severe, 7 - 9; and very severe, 10). Data for mild pain was limited because a small number of patients received interventions. For moderate pain, the mean difference in NRS pain score for BFA and ketorolac was 3.5 and 3.8, respectively; for severe pain, 3.4 and 5.3; and for very severe pain, 4.6 and 6.4. There was a larger difference in the preintervention and postintervention NRS pain scores within severe pain and very severe pain groups.

The mean difference in NRS pain score reduction between the intervention groups was not statistically significant for any subgroup (Figure).
table 4
A subgroup analysis also was performed comparing pain locations, although no statistically significant difference was found among the subgroups (Table 4).

Discussion

Both interventions resulted in a significant reduction in the mean NRS pain score of about 4 to 5 points within their group, and BFA resulted in a similar NRS pain score reduction compared with ketorolac 15 mg. Because the baseline NRS pain scores were significantly different between the BFA and ketorolac groups, a subgroup analysis revealed that BFA reduced mean NRS pain score in patients with severe and very severe pain but appears to be less beneficial for moderate pain, unlike the ketorolac results that showed a large reduction in all pain groups except for the small sample of patients with mild pain.

 

 

In this study, more patients in the BFA group presented to the ED with lower extremity pain, such as gout or neuropathy, compared with the ketorolac group; however, BFA did not result in a significantly different pain score reduction in this subgroup compared with ketorolac. Patients receiving BFA were more likely to receive topical analgesics or muscle relaxants at discharge; whereas those receiving ketorolac were significantly more likely to receive oral NSAIDs. Patients in this study also were more likely to be admitted to the hospital if they received ketorolac; however, for these patients, pain was secondary to their chief presentation, and the admitting physician’s familiarity with ketorolac might have been the reason for choosing this intervention. Reasons for the admissions were surgical observation, psychiatric stabilization, kidney/gallstones, rule out of acute coronary syndrome, pneumonia, and proctitis in the ketorolac group, and suicidal ideations in the BFA group.

Limitations

Because BFA required a consultation to be entered in the electronic health record, in addition to time needed to perform the procedure, practitioners might have preferred IV/IM ketorolac during busy times in the ED, potentially leading to underrepresentation in the BFA group. Prescribing preferences might have differed among the rotating physicians, timing of the documentation of the NRS pain score could have differed based on the treatment intervention, and the investigators were unable to control or accurately assess whether patients had taken an analgesic medication before presenting to the ED. Because pain and the treating physician are subjective, patients who reported a higher baseline pain severity might have been more likely to be discharged with topical analgesics or muscle relaxants. One way to correct for this subjectivity would be to conduct a larger prospective trial with a single treating physician. Finally, ED encounters in this study were short, and there was no follow-up permitting identification of AEs.

Conclusions

NRS pain score reduction with BFA did not differ compared with ketorolac 15 mg for treating acute and acute-on-chronic pain in the ED. Although this study was underpowered, these results add to the limited existing literature, suggesting that both interventions could result in clinically significant pain score reductions for patients presenting to the ED with severe and very severe pain, making BFA a viable nonpharmacologic option.

IUD-released levonorgestrel eases heavy menstrual periods

For women with excessive menstrual blood loss, the contraceptive levonorgestrel 52 mg delivered via an intrauterine device (IUD) reduced monthly blood loss by more than 90% over six monthly cycles, a multicenter open-label study reports.

Median blood loss decreased by more than 90% in the first three cycles. Overall, treatment was successful in 81.8% of 99 patients (95% confidence interval, 74.2%-89.4%), according to findings published in Obstetrics & Gynecology.

Dr. Mitchell Creinin


Already approved for contraception, the IUD (Liletta) had substantial benefits for quality of life in measures such as sleep, pain/cramping, and daily functioning, wrote a group led by Mitchell D. Creinin, MD, a professor in the department of obstetrics and gynecology at University of California, Davis.

“This study provides evidence of high efficacy, as expected, for the Liletta levonorgestrel 52 mg IUD for heavy menstrual bleeding treatment,” Dr. Creinin said in an interview.

Racially diverse cohort

Conducted at 29 U.S. sites prior to seeking FDA registration for this new use, the phase 3 open-label trial of the 52 mg progestin-releasing IUD enrolled 105 participants with a mean age of 35.4 years. Unlike previous trials, this one included obese or severely obese women (44.8%), with 42 participants having a body mass index (BMI) of more than 35 kg/m2, and also 28 nulliparous women (27.6%).

Those with abnormalities such as fibroids or coagulopathies were excluded. Although most of the cohort was White (n = 68), the study included Black (n = 25), Asian (n = 4), and Hispanic (n = 10) women, plus 7 from other minorities, suggesting the results would be widely applicable.

Mean baseline blood loss in the cohort ranged from 73 mL to 520 mL (median, 143 mL). Of 89 treated women with follow-up, participants had a median absolute blood-loss decreases of 93.3% (86.1%-97.8%) at cycle three and 97.6% (90.4%-100%) at cycle six. Median bleeding reductions at cycle six were similar between women with and without obesity at 97.6% and 97.5%, respectively, and between nulliparous and parous women at 97.0% and 98.1%, respectively (P = .43). The study, however, was not sufficiently powered to fully analyze these subgroups, the authors acknowledged.

Although results were overall comparable with those of a previous study on a different IUD, the expulsion rate was somewhat higher, at 9%, than the 6% reported in the earlier study.

“Although this strategy for reducing blood loss is not new, this study is notable because it looked at high-BMI women and nulliparous women,” said Kathryn J. Gray, MD, PhD, an attending physician in the department of obstetrics and gynecology at Brigham and Women’s Hospital in Boston, who was not involved in the research.“No prior trials have included patients with BMIs exceeding 35 kg/m2 or nulliparous patients, while this study enrolled a full array of patients, which allowed exploratory analyses of these subpopulations,” Dr. Creinin confirmed.

According to Dr. Gray, the IUD approach has advantages over systemic treatment with oral medication. “First, treatment is not user-dependent so the user doesn’t have to remember to take it. In addition, because the medication is locally targeted in the uterus, it is more effective and there is less fluctuation and variability in drug levels than when taken orally.”

As to treatment durability, Dr. Creinin said, “Long-term studies in a population being treated for heavy menstrual bleeding would be helpful to have an idea of how long this effect lasts. Still, there is no reason to expect that the effect will not last for many years.”

And with this treatment, he added, both patient and clinician can readily detect its effect. “If bleeding begins to increase, they will know!”

Would there be a lingering residual effect even after removal of the IUD? “That is an excellent question that remains to be answered,” Dr. Creinin said. “There are no data on when the heavy bleeding returns, but it would be expected to do so.”

This study was funded, designed, and supervised by Medicines360, which also provided the study treatment. Dr. Creinin disclosed financial relationships with various private-sector companies, including Medicines360, Organon, Fuji Pharma, GlaxoSmithKline, and Merck & Co. Multiple study coauthors disclosed similar financial ties to industry partners, including Medicines360. Dr. Gray had no potential conflicts of interest with regard to her comments.
