Poor adherence to medication is a real challenge in health care. Despite evidence indicating therapeutic benefit from adhering to a prescribed regimen, it is estimated that around 50% of patients around the world don’t take their medication as it is prescribed – and some simply don’t take them at all.

Nonadherence to medication can be primary or secondary. Primary medication nonadherence occurs when a new medication is prescribed for a patient, but the patient does not obtain the medication or an appropriate alternative within an acceptable period after it was prescribed. Secondary nonadherence measures prescription refills among patients who previously filled their first prescriptions. With most medication adherence research to date focused on secondary nonadherence, PMN has been identified as a major research gap.

Growth in electronic prescribing has partially resolved this issue, and new measures have emerged linking electronic prescribing databases with pharmacy dispensing databases. A study conducted in a network of primary care services in Canada has sought to identify the predictive factors of primary nonadherence and which drugs could be at greatest risk of primary nonadherence when prescribed by a primary care physician
 

Adherence measures

Measuring medication adherence is challenging but can be done using various approaches. It comprises the following approaches:

• Subjective measurements obtained by asking patients, family members, caregivers, and physicians about the patient’s medication use
• Objective measurements obtained by counting pills, examining pharmacy refill records, or using electronic medication event monitoring systems
• Biochemical measurements obtained by adding a nontoxic marker to the medication and detecting its presence in blood or urine or measurement of serum drug levels.

Determining factors

A myriad of factors contributes to poor medication adherence. Some are related to patients (e.g., suboptimal health literacy and lack of involvement in the treatment decision-making process), others are related to physicians (e.g., prescription of complex drug regimens, communication barriers, ineffective communication of information about adverse effects, and provision of care by multiple physicians), and still others are related to health care systems (e.g., office visit time limitations, limited access to care, and lack of health information technology).

Primary nonadherence

The literature has reported substantial variation in primary nonadherence, with estimates ranging from as little as 1.9% of incident prescriptions never filled to as much as 75%.

Investigators for the Canadian study estimated the rate of primary nonadherence, defined as failure to dispense a new medication or its equivalent within 6 months of the prescription date, using data from 150,565 new prescriptions issued to 34,243 patients.
 

Rate of nonadherence

The following patterns of primary nonadherence were observed:

• Primary nonadherence was lowest for prescriptions issued by prescribers aged 35 years or younger (17.1%) and male prescribers (15.1%).
• It was similar among patients of both sexes.
• It was lowest in the oldest subjects, decreasing with age (odds ratio, 0.91 for each additional 10 years).
• It was highest for drugs prescribed mostly on an as-needed basis, including topical corticosteroids (35.1%) and antihistamines (23.4%).

Predictors of nonadherence

The odds of primary nonadherence exhibited the following patterns:

• Lower for prescriptions issued by male clinicians (OR, 0.66)
• Significantly greater, compared with anti-infectives, for dermatological agents (OR, 1.36) and lowest for cardiovascular agents (OR, 0.46).
• Lower across therapeutic drug categories (except for respiratory agents) for those aged 65 years and older than for those younger than age 65.

In conclusion, in a general medicine setting, the odds of primary nonadherence were higher for younger patients, those who received primary care services from female prescribers, and older patients who were prescribed more medications. Across therapeutic categories, the odds of primary nonadherence were lowest for cardiovascular system agents and highest for dermatological agents.

To date, the lack of a standardized terminology, operational definition, and measurement methods of primary nonadherence has limited our understanding of the extent to which patients do not avail themselves of prescriber-ordered pharmaceutical treatment. These results reaffirm the need to compare the prevalence of such nonadherence in different health care settings.

• Subjective measurements obtained by asking patients, family members, caregivers, and physicians about the patient’s medication use
• Objective measurements obtained by counting pills, examining pharmacy refill records, or using electronic medication event monitoring systems
• Biochemical measurements obtained by adding a nontoxic marker to the medication and detecting its presence in blood or urine or measurement of serum drug levels.

Determining factors

A myriad of factors contributes to poor medication adherence. Some are related to patients (e.g., suboptimal health literacy and lack of involvement in the treatment decision-making process), others are related to physicians (e.g., prescription of complex drug regimens, communication barriers, ineffective communication of information about adverse effects, and provision of care by multiple physicians), and still others are related to health care systems (e.g., office visit time limitations, limited access to care, and lack of health information technology).

Primary nonadherence

The literature has reported substantial variation in primary nonadherence, with estimates ranging from as little as 1.9% of incident prescriptions never filled to as much as 75%.

Investigators for the Canadian study estimated the rate of primary nonadherence, defined as failure to dispense a new medication or its equivalent within 6 months of the prescription date, using data from 150,565 new prescriptions issued to 34,243 patients.
 

Rate of nonadherence

The following patterns of primary nonadherence were observed:

• Primary nonadherence was lowest for prescriptions issued by prescribers aged 35 years or younger (17.1%) and male prescribers (15.1%).
• It was similar among patients of both sexes.
• It was lowest in the oldest subjects, decreasing with age (odds ratio, 0.91 for each additional 10 years).
• It was highest for drugs prescribed mostly on an as-needed basis, including topical corticosteroids (35.1%) and antihistamines (23.4%).

Predictors of nonadherence

The odds of primary nonadherence exhibited the following patterns:

• Lower for prescriptions issued by male clinicians (OR, 0.66)
• Significantly greater, compared with anti-infectives, for dermatological agents (OR, 1.36) and lowest for cardiovascular agents (OR, 0.46).
• Lower across therapeutic drug categories (except for respiratory agents) for those aged 65 years and older than for those younger than age 65.

In conclusion, in a general medicine setting, the odds of primary nonadherence were higher for younger patients, those who received primary care services from female prescribers, and older patients who were prescribed more medications. Across therapeutic categories, the odds of primary nonadherence were lowest for cardiovascular system agents and highest for dermatological agents.

To date, the lack of a standardized terminology, operational definition, and measurement methods of primary nonadherence has limited our understanding of the extent to which patients do not avail themselves of prescriber-ordered pharmaceutical treatment. These results reaffirm the need to compare the prevalence of such nonadherence in different health care settings.

Poor adherence to medication is a real challenge in health care. Despite evidence indicating therapeutic benefit from adhering to a prescribed regimen, it is estimated that around 50% of patients around the world don’t take their medication as it is prescribed – and some simply don’t take them at all.

Nonadherence to medication can be primary or secondary. Primary medication nonadherence occurs when a new medication is prescribed for a patient, but the patient does not obtain the medication or an appropriate alternative within an acceptable period after it was prescribed. Secondary nonadherence measures prescription refills among patients who previously filled their first prescriptions. With most medication adherence research to date focused on secondary nonadherence, PMN has been identified as a major research gap.

Growth in electronic prescribing has partially resolved this issue, and new measures have emerged linking electronic prescribing databases with pharmacy dispensing databases. A study conducted in a network of primary care services in Canada has sought to identify the predictive factors of primary nonadherence and which drugs could be at greatest risk of primary nonadherence when prescribed by a primary care physician

TOPLINE:

Drug use disorder increased the likelihood of in-hospital mortality more than 10-fold in patients with ankylosing spondylitis (AS), compared with patients who did not die while hospitalized.

METHODOLOGY:

• Researchers reviewed data from 2,125 adults with AS who were hospitalized between 2015 and 2017, using the Cerner Health Facts Database.
• The final analysis included 41 patients with AS who died while hospitalized and 260 random control patients with AS who did not die.
• The mean age of the deceased patients with AS was 70 years, 85% were male, and 81% were White; 71% had hypertension, 32% had kidney disease, and 22% had congestive heart failure.

TAKEAWAY:

• Among the patients with AS, cardiovascular disease was the most frequent cause of death, followed by infection, respiratory failure, and fracture/trauma in 15, 14, 8, and 7 patients, respectively. (Some patients had more than one cause of death recorded in the discharge summary.)
• The most common cardiac causes of death were myocardial infarction and cardiac arrest, while the top causes of acute respiratory failure were pneumonia and pulmonary embolism.
• Drug abuse, including opioid dependence, was significantly associated with death among hospitalized patients with AS (adjusted odds ratio, 10.9; P = .001).
• Heart failure and kidney disease were the comorbidities most strongly associated with mortality; the odds of death in the presence of heart failure rose 2.76-fold, and it increased 2.46-fold in the presence of kidney disease.

IN PRACTICE:

Underlying comorbidities, especially cardiac and renal, are associated with mortality in AS, and patients should be screened early on for these comorbidities to help reduce the odds of death.

SOURCE:

First author Mohamad Bittar, MD, of the University of Tennessee Health Science Center, Memphis, and colleagues reported their findings in Clinical Rheumatology).

LIMITATIONS:

The study lacked AS-specific data such as disease activity scores, which were not in the database. Also missing were variables linked to disease activity and mortality, including smoking, BMI levels, and C-reactive protein levels.

DISCLOSURES:

The study received no outside funding. Several coauthors disclosed financial relationships with UCB, Amgen, Pfizer, AbbVie, Novartis, and Eli Lilly.

Adults with nonsevere community-acquired pneumonia (CAP) responded nearly equally to three first-line and alternative antibiotic regimens, based on data from more than 23,000 individuals.

Current recommendations for the treatment of CAP vary across guidelines, wrote Anthony D. Bai, MD, of Queen’s University, Kingston, Ont., and colleagues. However, most guidelines were based on studies that were not powered to examine the effect of treatments on mortality, they said.

“Large observational studies could fill this gap by comparing multiple treatment arms, including patients not well represented in trials, and having a large sample size powered to detect a difference in mortality,” they noted.

In a study published in Chest, the researchers reviewed data from 23,512 consecutive patients admitted to 19 hospitals in Canada for CAP between 2015 and 2021. Patients were treated with one of four initial antibiotic regimens: beta-lactam plus macrolide (BL+M), beta-lactam alone (BL), respiratory fluoroquinolone (FQ), or beta-lactam plus doxycycline (BL+D). Of these, BL+M is generally considered the first-line regimen, the researchers noted.

Patients were divided into four groups according to their initial antibiotic treatment within 48 hours of admission; 9,340 patients received BL+M, 9,146 received BL, 4,510 received FQ, and 516 received BL+D. The duration of any antibiotic that was active against CAP was at least 4 days, or until hospital discharge or death.

The primary outcome was all-cause in-hospital mortality, which was 7.5%, 9.7%, 6.7%, and 6.0% for patients in each of the four treatment groups, respectively. Relative to the first-line therapy of BL+M, the adjusted risk differences for BL, FQ, and BL+D were 1.5%, –0.9%, and –1.9%, respectively.

The adjusted in-hospital mortality was not significantly different between BL+M and either FQ or BL+D, but the difference of 1.5% seen with BL alone suggested a “small but clinically important difference,” the researchers noted.

Key secondary outcomes were the length of hospital stay and being discharged alive. The median length of stay was 4.6 days for BL+M, 5.2 days for BL, 4.6 days for FQ, and 6.0 days for BL+D. Patients treated with BL also had a longer time to hospital discharge, which suggests that BL may not be as effective as the other regimens, the researchers said. In addition, patients in the BL group had a subdistribution hazard ratio of 0.90 for being discharged alive, compared with the BL+M group after adjustment with propensity scores and overlap weighting.

Overall, the results support dropping BL as a first-line regimen in the current ATS/IDSA guidelines, and support the recommendation of BL+M, FQ, and BL+D as similarly effective options as listed in other guidelines, applied according to other patient characteristics. For example, “Doxycycline may be preferred over a macrolide in many cases such as macrolide allergy, prolonged QT, or high [Clostridioides] difficile risk,” the researchers said.

The findings were limited by several factors including the lack of follow-up data after hospital discharge.

However, the results were strengthened by the large sample size and use of a comprehensive database that allowed adjustment for many variables, as well as the availability of complete follow-up data for the time spent in the hospital. Based on this study, clinicians may choose a respiratory fluoroquinolone, a beta-lactam plus macrolide, or a beta-lactam plus doxycycline for equally effective antibiotic treatment of CAP, based on the best fit for each individual patient, the researchers concluded.

The study received no outside funding. The researchers had no financial conflicts to disclose.

A silent disorder is rising among older people worldwide, as millions unknowingly grapple with glaucoma, ophthalmologists warn.

It’s predicted that by 2050, the number of people with glaucoma will surge by more than 200%, highlighting an urgent need for heightened awareness, early detection, and advanced treatment strategies.

“That’s a lot of people with a blinding disease who don’t know they have it,” said Joel S. Schuman, MD, professor of ophthalmology and codirector of the Glaucoma Service at Wills Eye Hospital in Philadelphia. “Late in the disease, people may notice they’re tripping over the curb, or walking into things they didn’t see. It really is only in very advanced disease that people notice there’s anything wrong.”

Glaucoma is the second leading cause of blindness worldwide, affecting 3 million people in the United States, and yet half of those affected are unaware, according to the Centers for Disease Control and Prevention. 

Recent research at the University of Gothenburg in Sweden underscores glaucoma’s stealthy nature: Five percent of 560 70-year-olds had the disease, and half of those did not know they had it before they took part in the study. 

“Living with glaucoma, especially without realizing it, can be very isolating,” said Lena Havstam Johansson, a PhD student at the University of Gothenburg and a specialist nurse at Sahlgrenska University Hospital, who did the study. “It may lead people to stay at home to avoid the trouble.”

Once symptoms arise, some may notice patchy blind spots in their peripheral vision, and in their central vision in late stages.

While many people assume they are getting clumsier with age, Dr. Schuman said, they often have a condition that can be slowed with the right treatment. 

Though there are various types of the disease, about 9 in 10 people in the United States have primary open-angle glaucoma (POAG).  

It is most common among people over the age of 60, those with a family history of glaucoma, and people who have diabetes. It disproportionately affects Black people, who are six times more likely than are White people to have advanced vision loss from the disease. 

More than 120,000 people in the United States are blind from glaucoma, accounting for 9%-12% of all cases of blindness. Glaucoma treatments range from eye drops to laser treatments to surgery, all of which aim to reduce eye pressure. Some doctors will recommend oral medication along with eye drops.

“We have a lot of treatment options, and they work pretty well,” Dr. Schuman said. “But the first step is the person knowing they have glaucoma, and the second step is that person seeking care.

Rarer types of glaucoma include normal-tension glaucoma, which is more common among people of Japanese ancestry, and congenital glaucoma, which affects about 1 in 10,000 babies born in the United States.

The best way to ensure early detection and treatment is to get regular eye exams – every 2-4 years for adults under the age of 55, and annually thereafter, said Annie Wu, MD, clinical assistant professor of ophthalmology at the Kellogg Eye Center at the University of Michigan. 

The fact that glaucoma’s symptoms are slow to develop, coupled with a lack of access to eye specialists many Americans face, makes the disease even more dangerous. 

The University of Pennsylvania is among those trying to change that. The Philadelphia school has hosted free glaucoma screening programs for Black residents.  

There are a number of organizations that offer access to free glaucoma screening.

More than 120,000 people in the United States are blind from glaucoma, accounting for 9%-12% of all cases of blindness. Glaucoma treatments range from eye drops to laser treatments to surgery, all of which aim to reduce eye pressure. Some doctors will recommend oral medication along with eye drops.

“We have a lot of treatment options, and they work pretty well,” Dr. Schuman said. “But the first step is the person knowing they have glaucoma, and the second step is that person seeking care.

Rarer types of glaucoma include normal-tension glaucoma, which is more common among people of Japanese ancestry, and congenital glaucoma, which affects about 1 in 10,000 babies born in the United States.

The best way to ensure early detection and treatment is to get regular eye exams – every 2-4 years for adults under the age of 55, and annually thereafter, said Annie Wu, MD, clinical assistant professor of ophthalmology at the Kellogg Eye Center at the University of Michigan. 

The fact that glaucoma’s symptoms are slow to develop, coupled with a lack of access to eye specialists many Americans face, makes the disease even more dangerous. 

The University of Pennsylvania is among those trying to change that. The Philadelphia school has hosted free glaucoma screening programs for Black residents.  

There are a number of organizations that offer access to free glaucoma screening.
