Biologics May Improve Outcomes in Overlapping COPD and Asthma
Use of biologics significantly reduced exacerbations and hospitalizations in adults with chronic obstructive pulmonary disease (COPD) and overlapping type 2 asthma inflammation, based on data from a new study presented at the American Thoracic Society’s international conference.
Patients diagnosed with COPD on maximum medical therapy may continue to have disease exacerbations that are highly morbid and are associated with worsening lung function, increased hospitalizations, and worsened mortality, said lead author Stephen Dachert, MD, Temple University Hospital, Philadelphia, in an interview.
Previous research has examined the association between use of individual biologics and reduction in acute exacerbations of COPD, but real-world data on the use of biologics for COPD and asthma-COPD overlap syndrome (ACOS) are lacking, Dr. Dachert and colleagues wrote in their abstract.
In the current study, the researchers reviewed data from 53 adults with COPD who were seen at a single center; 30 had ACOS, and 23 had COPD only. The mean age of the participants was 68.2 years, approximately half were White/Caucasian individuals, 26% were Black/African American individuals, 17% were Hispanic individuals, 4% were Asian individuals/Pacific Islanders, and 2% were from other races/ethnicities; 62% were women. The study population included patients with prior diagnosis codes for COPD and dupilumab, mepolizumab, benralizumab, or tezepelumab; the mean eosinophil count before biologics initiation was 471.
Reduction in Exacerbations and Hospitalizations
The researchers assessed change in exacerbations, hospitalizations, and spirometry from 1 year before to 1 year after initiation of treatment with biologics. Overall, after the use of biologics, patients experienced a significant mean reduction in exacerbations and hospitalizations of 1.780 and 0.944, respectively (both P < .001, using a paired T-test).
In addition, the researchers found a mean reduction of forced expiratory volume per second percent predicted of 0.57% and a mean increase in forced vital capacity percent predicted of 1.3% after the initiation of biologics.
Increases also occurred in total lung capacity percent predicted, residual volume percent predicted, and diffusing capacity of the lungs for carbon monoxide (DLCO) percent predicted (3.37%, 9.90%, and 4.58%, respectively). Of these, only DLCO percent predicted approached statistical significance, the researchers wrote.
The study findings make sense physiologically, Dr. Dachert said in an interview. “If large, randomized trials have shown a reduction in exacerbations in patients with type 2 inflammation asthma, it makes sense that we would see similar results in patients with COPD and type 2 inflammation,” he said. However, as yet only one of several large randomized trials has shown reductions in exacerbations and COPD with type 2 inflammation, he added.
“In our real-world cohort, we saw both a reduction in exacerbations and hospitalizations in the year following initiation of biologic therapy,” Dr. Dachert said. A reduction in hospitalizations, in particular, had not previously been shown in this population, he noted.
The findings were limited by the retrospective design and use of data from a single center; moreover, larger real-world studies are needed to confirm the results, said Dr. Dachert. “As we add patients to our cohort, we may be able to identify which clinical characteristics/risk factors may be associated with an even more robust reduction in exacerbations or hospitalizations,” he said.
“Our cohort of patients was more diverse than those included in prior randomized clinical trials and also has high rates of emphysema and airflow obstruction, populations typically excluded in large randomized trials,” he said.
Data Support the Potential of Biologics for COPD
Biologic agents have been effective in reducing asthma exacerbations, and understanding their effectiveness in reducing COPD exacerbations in a real-world setting is important, said Arianne K. Baldomero, MD, assistant professor of medicine at Minneapolis VA Health Care System, Minneapolis, in an interview.
Dr, Baldomero said she was not surprised by the current study results “as clinical trials are showing similar findings among this group of patients with elevated eosinophil counts.”
The current study adds to the growing evidence supporting the use of biologics to reduce COPD exacerbations, Dr. Baldomero told this news organization. “I anticipate that we will soon begin using biologics to manage frequent exacerbations in patients with COPD,” she said.
“For both asthma and COPD, more research is needed to guide clinicians in tapering or weaning down biologic treatment and determining whether patients still need to use inhalers,” Dr. Baldomero added.
The study received no outside funding. The researchers and Dr. Baldomero had no financial conflicts to disclose.

Abemaciclib Plus Fulvestrant Improves Survival in Advanced Breast Cancer
Disease progression is common in these patients, for whom first-line treatment is cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors plus endocrine therapy, Kevin Kalinsky, MD, of the Winship Cancer Institute of Emory University, Atlanta, said in a presentation at the American Society of Clinical Oncology (ASCO) annual meeting.
A need exists for additional targeted therapies for patients with advanced hormone receptor (HR)+, HER2- breast cancer whose tumors have progressed on endocrine therapy plus a CDK4/6 inhibitor, he said.
Data on the benefits of continuing CDK4/6 inhibitor therapy after progression have been mixed in phase 2 trials, Dr. Kalinsky noted in his presentation. Abemaciclib, an oral CDK4/6 inhibitor, has shown more selectivity for CDK 4 than CDK 6, and is approved in combination with fulvestrant or an aromatase inhibitor for advanced breast cancer, he said.
In a phase 3 study known as postMONARCH, the researchers randomized 182 patients to abemaciclib plus fulvestrant and 186 to placebo plus fulvestrant. The primary endpoint was progression-free survival (PFS) based on investigator assessment; secondary endpoints included PFS based on blinded independent central review (BICR), objective response rate (ORR), and safety.
The PFS rates at 6 months were 50% and 37% for the abemaciclib and placebo arms, respectively.
In the primary analysis, abemaciclib led to a 27% reduction in risk of investigator-assessed progression-free survival events compared with the placebo (117 vs. 141 events, hazard ratio 0.73, P = 0.02).
The study population included men and pre- and postmenopausal women with advanced HR+, HER2- breast cancer and progression after initial CDK4/6 plus endocrine therapy from 96 centers in 16 countries, enrolled between March 2022 and June 2023. The median age of the patients in the abemaciclib and placebo groups was 58 years and 61 years, respectively. Patients underwent scans every 8 weeks for the first 12 months, then every 12 weeks. Most of the patients were enrolled immediately after CDK4/6i + ET as initial therapy for advanced breast cancer. The most common previous CDK4/6 inhibitor therapy was palbociclib (59%), followed by ribociclib (33%) and abemaciclib (8%).
Secondary Endpoints Also Favor Abemaciclib
The effects in favor of abemaciclib were consistent across subgroups, regardless of the presence or absence of baseline genetic mutations (ESR1 or PIK3CA), Dr. Kalinsky said in his presentation.
Overall response rate was significantly improved in the abemaciclib group compared with the placebo group in patients with measurable disease (17% vs. 7%) and PFS according to BICR also significantly improved (HR 0.55).
The magnitude of benefit was less in the subgroup of patients with visceral metastases, Dr. Kalinsky noted.
“Safety was consistent with what is known about the abemaciclib profile,” he added. Six percent of abemaciclib patients discontinued treatment because of adverse events.
The study is the first phase 3 trial to show improvement with CDK4/6 inhibition therapy with a combination of abemaciclib and fulvestrant and offers a new option for patients with HR+, HER2- advanced breast cancer not selected for biomarker status, Dr. Kalinsky concluded.
Data Support Switching CDK Inhibitors in Absence of Mutations
Switching CDK inhibitors to abemaciclib plus endocrine therapy significantly prolonged progression-free survival compared with endocrine therapy alone, with especially pronounced improvement in those without visceral metastases and those with longer durations of first-line CKD4/6 inhibitor therapy, said Ruth O’Regan, MD, of the University of Rochester, New York, who served as the discussant for the new research.
Dr. Regan referenced the improvement with abemaciclib in the BICR, a technique used to identify potential bias introduced by the assessment of local investigators. This can result in more favorable PFS on a treatment arm as seen in this study, but its use generally does not impact overall trial results, she said.
In the context of other studies involving switching CDK 4/6 inhibitors post-progression, the difference of 0.7 months in PFS between the abemaciclib and placebo groups was less than the 2.5 months difference seen in the MAINTAIN trial and the 1.3 months difference seen in the PALMIRA trial, Dr. O’Regan said in her presentation. Conversely, in the PACE trial, the intervention group did worse (4.6 months) than the control group in terms of the PFS (4.8 months), she said. Overall, the results of the postMONARCH trial support the use abemaciclib in patients with no actionable genetic mutation, she said.
In a question-and-answer session, Dr. Kalinsky was asked whether clinicians should still bother with genetic testing, since patients in the current study showed benefits regardless of the presence or absence of a mutation.
“I would still recommend that we check for mutations,” he emphasized. The current study “is one chapter in a much larger book,” and the field continues to evolve, he said.
A Clinician’s Take
“Currently, no standard second-line treatment after progression on first line CDK4/6 inhibitor plus endocrine therapy exists,” Malinda T. West, MD, of the University of Wisconsin, Madison, said in an interview. “Using a different CDK4/6 inhibitor after progression on a first CDK4/6 inhibitor has mixed data,” she said.
“If benefit with a second CDK4/6 inhibitor is confirmed, it may represent an additional low toxicity, chemotherapy-sparing regimen,” she noted.
Earlier data from the MAINTAIN trial had shown benefit with using ribociclib after progression on a primarily first line palbociclib, though other trials looking at use of palbociclib after progression on CDK 4/6 inhibitor [including the PACE and PALMIRA trials] had not, she said.
Overall, the results from postMONARCH support that switching the CDK4/6 inhibitor at progression to ribociclib or abemaciclib may be another treatment option, and reasonable for patients who don’t have other actionable mutations, Dr. West told this news organization.
The study was supported by Eli Lilly. Dr. Kalinsky disclosed that immediate family members are employed by EQRx and GRAIL, with stock or other ownership interests in these companies. He disclosed consulting or advisory roles with 4D Pharma; AstraZeneca; Cullinan Oncology; Daiichi Sankyo/AstraZeneca; eFFECTOR Therapeutics; Genentech/Roche; Immunomedics; Lilly; Menarini Silicon Biosystems; Merck; Mersana; Myovant Sciences; Novartis; Oncosec; Prelude Therapeutics; Puma Biotechnology; RayzeBio; Seagen; and Takeda.

Dupilumab May Reduce Exacerbations in COPD, Type 2 Inflammation
Dupilumab significantly reduced exacerbations and improved lung function in adults with uncontrolled chronic obstructive pulmonary disease (COPD) and type 2 inflammation, based on data from more than 900 individuals.
Data from a phase 3 trial known as NOTUS were presented at the American Thoracic Society’s international conference and published simultaneously in The New England Journal of Medicine.
Dupilumab, a fully human monoclonal antibody, works by inhibiting the signaling of the interleukin 4 (IL-4) and IL-13 pathways and is approved for many conditions characterized by type 2 inflammation, wrote Surya P. Bhatt, MD, of The University of Alabama at Birmingham, and colleagues in the NEJM study.
“Last year, we showed in the BOREAS trial that dupilumab was very effective in lowering exacerbation frequency in patients with COPD who continued to have frequent exacerbations despite being on maximal inhaled therapy,” Dr. Bhatt said in an interview.
12 Months of COPD, Triple Inhaler Therapy
In the NOTUS study, the researchers randomized 470 adults with uncontrolled COPD and type 2 inflammation (defined as a blood eosinophil count of ≥ 300 cells/µL) to 300-mg subcutaneous dupilumab and 465 to a placebo every 2 weeks. Patients were enrolled between July 2020 and May 2023.
The study population included adults aged 40-85 years with physician-diagnosed COPD for at least 12 months who had received background triple inhaler therapy (an inhaled glucocorticoid agent plus long-acting muscarinic antagonist [LAMA]–long-acting beta-agonist [LABA] or LAMA-LABA alone) for at least 3 months and at a stable dose for at least 1 month. All participants were current or former smokers with a smoking history of at least 10 pack-years.
The primary endpoint was a reduction in the annualized rate of moderate or severe COPD exacerbations at 52 weeks.
Patients in the dupilumab group also saw a significantly greater improvement in lung function compared with individuals in the placebo group based on prebronchodilator forced expiratory volume in 1 second from baseline to 12 weeks (least squares mean change of 139 mL vs 57 mL). This improvement was sustained at 52 weeks (least squares mean change of 115 mL vs 54 mL).
Improvement in respiratory symptom severity based on the St. George’s Respiratory Questionnaire was another secondary endpoint, and changes in total score were greater in the dupilumab group than in the placebo group (least squares mean change of 9.8 vs 6.4).
Safety outcomes were similar between the dupilumab and placebo groups, with approximately 66% of patients in each group reporting adverse events during the 52-week study period. Serious adverse events occurred in 13% and 15.9% of dupilumab and placebo patients, respectively, and adverse events resulting in death occurred in 2.6% and 1.5%, respectively. The most common adverse events were COVID-19, which occurred in 9.4% and 8.2% of the dupilumab and placebo patients, respectively, followed by headache, COPD, and nasopharyngitis. Major adverse cardiovascular events occurred in three patients in the dupilumab group and seven patients in the placebo group.
The findings were limited by several factors including the reduced sample size for 52-week endpoints because of the earlier analysis and the primarily White study population, the researchers noted. The study was conducted in part during the COVID-19 pandemic period, which contributed to healthcare disruptions and behavior changes that decreased exposure to viral respiratory infections, they wrote in their discussion. However, the results were strengthened by the large numbers and international population without other major pulmonary diseases, such as asthma, and the 34% reduction in exacerbations with dupilumab vs placebo is clinically significant, they said.
Data May Drive US Food and Drug Administration (FDA) Approval
In the BOREAS trial, dupilumab also improved lung function and quality of life, with no notable safety concerns. “As with any trial evaluating the efficacy and safety of a medication, it is important to confirm the findings in a replicative study,” said Dr. Bhatt. “With NOTUS, we confirmed the findings of BOREAS,” and the researchers were reassured by the substantial reduction in exacerbation frequency and the replication of key secondary outcomes, he said.
With the NOTUS study, “two randomized trials have now shown near identical reductions in exacerbation frequency in a difficult-to-treat population of patients with COPD with type 2 inflammation and frequent exacerbations,” as well as a significant and meaningful improvement in lung function, Dr. Bhatt said in an interview. “We hope these trials pave for the way for regulatory body approval of dupilumab for clinical use,” he said. Looking ahead, more studies are needed to test the potential disease modification effects of dupilumab in patients with COPD, he added.
Potential Change in Patient Management
Approximately 20%-40% of patients with COPD have type 2 inflammation with elevated blood eosinophil count, and this subset of patients has an increased risk for exacerbations, with worsening lung function and quality of life, Dharani K. Narendra, MD, of Baylor College of Medicine, Houston, said in an interview.
Prior phase 3 studies have shown that dupilumab, a blocker of IL-4 and IL-13 pathways, could effectively reduce exacerbations and improve lung function in these patients, and the NOTUS study aimed to confirm the findings in a larger, more diverse population, said Dr. Narendra, who was not involved in the study.
The NOTUS study represents a paradigm shift in the management of COPD patients with type 2 inflammation, said Narendra. “This study validates the previous BOREAS trial and has shown that dupilumab reduces exacerbations, improves lung function and quality of life, and potentially slows disease progression,” she said.
If approved, potential barriers to the use of dupilumab in practice include cost and insurance coverage, education and dissemination of study findings, and limited data on side effects, said Dr. Narendra.
“While the NOTUS study provides valuable insights into the efficacy and safety of dupilumab over 52 weeks, longer-term studies are needed to understand the sustained benefits and risks of continued treatment,” Dr. Narendra told this news organization. “Studies comparing dupilumab with other biological agents and newer COPD treatments could provide insights into its relative efficacy and position in treatment protocols,” she said.
In addition, further research into dupilumab’s underlying mechanisms could provide deeper insights into the pathophysiology of type 2 inflammation in COPD and inform the development of new treatments, Dr. Narendra said. “These steps will help integrate dupilumab more effectively into clinical practice and optimize its use for COPD patients with type 2 inflammation,” she noted.
Dupilumab is undergoing Priority Review by the FDA as an add-on maintenance therapy for adults with uncontrolled COPD and type 2 inflammation, with a target action date of June 27, 2024, according to a company press release.
The study was funded by Sanofi and Regeneron Pharmaceuticals. Dr. Narendra had no financial conflicts to disclose but serves on the Editorial Advisory Board of CHEST Physician.

Understudied Patients With COPD Benefit From BLVR
BLVR has shown promising results in previous studies for carefully selected patients with COPD, said Michael J. Nicholson, DO, of Temple University Hospital, Philadelphia. However, those with AATD have often been excluded from large BLVR trials, so data on its effectiveness in this population are limited, he said.
“The distinct pathophysiology of AATD poses challenges in extrapolating findings from trials involving COPD patients without AATD,” Dr. Nicholson noted. “Variations in affected lung lobes and disease progression are major differences between the AATD and non-AATD populations; we sought to examine if BLVR could provide significant, sustained benefit to AATD patients despite their differences from the typical COPD cohort,” he said.
Patients With COPD and AATD
In a study presented at the American Thoracic Society (ATS) 2024 International Conference, Dr. Nicholson and colleagues reviewed data from 238 adults with COPD including 14 with AATD who underwent BLVR at a single center between August 2018 and December 2022. Pulmonary function test data were collected at baseline and at a median of 7 months post-BLVR. The mean age of patients with AATD was 61.5 years, and 79% were men.
The primary outcome was the percentage of patients with forced expiratory volume per second (FEV1) improvement greater than 15%. Half of the patients with AATD achieved this outcome, with a median improvement in FEV1 of 110 mL and a significant difference in pre- and post-BLVR FEV1 volume based on a Wilcoxon signed rank test (W = 11.5; P < .05).
Patients with AATD also showed significant improvement in several secondary outcomes including BODE index, residual volume (RV), total lung capacity (TLC), RV/TLC ratio, and inspiratory capacity/RV ratio between pre- and post-BLVR.
“The sustained improvements seen at 7 months post-BLVR in patients with lower lobe disease were unexpected and promising,” Dr. Nicholson said in an interview. “In contrast to the National Emphysema Treatment Trial (NETT), which found lung volume reduction surgery ineffective for lower lobe disease, our study revealed significant improvements in lower lobe disease following BLVR,” he said. The sustained improvements up to 7 months post-BLVR are encouraging, given clinical concerns that the ongoing destruction of lung tissue in AATD could cause initial BLVR improvements to regress, he added.
Overall, the results suggest that BLVR is an effective therapy for appropriately selected patients with AATD and COPD, and that significant improvement in lung function can be achieved regardless of the affected lobe, Dr. Nicholson said.
“The primary obstacles to widespread BLVR implementation include the scarcity of equipment, as well as insufficient education and training for pulmonologists outside of major academic institutions,” Dr. Nicholson told this news organization. “Successful outcomes in BLVR require clinicians to have a deep understanding of patient selection criteria, extensive training in BLVR techniques, and access to the necessary technology within their facilities,” he said. However, BLVR has been integrated into pulmonary and interventional pulmonary fellowships nationwide, which paves the way for a new generation of pulmonologists to expand the use of the procedure, he said.
Looking ahead, prospective examination of BLVR vs the current standard of care in patients with AATD would provide invaluable data, Dr. Nicholson said. Since the presentation of the study at the meeting, additional patient data have been added to the analysis and increased the power of the findings, he said. “We intend to extend our assessment of pulmonary function testing beyond 7 months post-BLVR to evaluate the persistence of improvements in the long term,” he added.
Study Confirms Benefits for Wider Patient Population
“Lung volume reduction is an important intervention in patients with severe emphysema,” said David M. Mannino, MD, of the University of Kentucky, Lexington, Kentucky, in an interview. Most emphysema is in the upper lobes, but it tends to occur more in the lower lobes in patients with AATD, said Dr. Mannino, who was not involved in the study.
The findings were not especially surprising, but they were reassuring, Dr. Mannino told this news organization. “We know this intervention works in those with severe emphysema,” and it was helpful to confirm similar success in patients with AATD, he said.
The implications for practice are that BLVR is both a safe and an effective intervention for patients with lower or upper lobe emphysema, although longer-term follow-up studies are needed, he said.
The study received no outside funding. Dr. Nicholson and Dr. Mannino had no financial conflicts to disclose.

Most emphysema is in the upper lobes, but it tends to occur more in the lower lobes in patients with AATD, said Dr. Mannino, who was not involved in the study.
The findings were not especially surprising, but they were reassuring, Dr. Mannino told this news organization. “We know this intervention works in those with severe emphysema,” and it was helpful to confirm similar success in patients with AATD, he said.
The implications for practice are that BLVR is both a safe and an effective intervention for patients with lower or upper lobe emphysema, although longer-term follow-up studies are needed, he said.
The study received no outside funding. Dr. Nicholson and Dr. Mannino had no financial conflicts to disclose.

Educational Tool Reduces Unnecessary Inhaler Use in ILD
Use of an electronic tool contributed to the deprescribing of unnecessary inhalers in patients with interstitial lung disease (ILD), based on data from nearly 200 individuals.
Patients with ILD often have symptoms that overlap with those of obstructive airways diseases, Stephanie Nevison, MD, of the University of Toronto, and colleagues wrote in a study presented at the American Thoracic Society’s international conference.
, they noted.
“Our aim was twofold: To quantify the extent of inappropriate inhaler use in patients with ILD and to discontinue them where appropriate,” the researchers wrote.
“We hypothesized that inappropriate inhaler use in ILD is common and that an electronic initiative would improve deprescribing rates,” they said.
The researchers conducted a quality improvement project in an ILD clinic at a single center. They reviewed 5 months of baseline data for 191 patients with ILD to assess baseline frequency of inappropriate inhaler use, defined as one or more of the following criteria: Reported asthma history, smoking history of > 15 pack/years, emphysema on chest CT, patient-reported benefits from therapy, airflow obstruction, or bronchodilator response on spirometry.
A total of 48 patients (25.1%) were on inhalers, and 15 (7.8%) had no indication for them (9% of new referrals and 7% of follow-up patients). The most-prescribed inhalers for patients with no indication were corticosteroids (10 patients), short-acting beta-agonists (8 patients), and long-acting beta-agonists (7 patients).
None of the patients on inhalers received counseling about discontinuing their use. The results of the baseline assessment were shared with clinicians along with education about reducing unnecessary inhaler use in the form of a prompt linked to electronic medical records to discuss deprescription of unnecessary inhalers.
The electronic intervention was applied in 400 of 518 patient encounters, and the researchers reviewed data over another 5-month period. A total of 99 patients were on inhalers, and 3.3% had no indication (5.3% of new referrals and 3.0% of follow-up patients). In the wake of the intervention, “all patients on unnecessary inhalers were counseled on deprescribing, representing a significant increase compared to the preintervention period,” the researchers wrote.
Intervention Shows Potential to Curb Unnecessary Inhaler Use
More research is needed as the findings were limited by the relatively small sample size and use of data from a single center, the researchers noted.
However, the results suggest that electronic reminders are effective for prompting a review of inhaler use, and deprescribing inappropriate inhalers for patients with ILD could reduce the potential for adverse events associated with their use, they concluded.
The current study is important because some patients with ILD may not benefit from inhaler use, David Mannino, MD, of the University of Kentucky, Lexington, said in an interview. In the study, “I was a bit surprised that only 3.3% of patients had no indication for them; this seems rather low,” said Dr. Mannino, who was not involved in the study.
Use of an electronic system that evaluates patients and flags inappropriate therapy is an effective way to decrease overprescribing of medications, Dr. Mannino told this news organization.
As for additional research, application of the tool used in this study to other pulmonary populations could be interesting and potentially useful, he said.
The study received no outside funding. The researchers and Dr. Mannino had no financial conflicts to disclose.

USPSTF Recommends Exercise To Prevent Falls in Older Adults
Exercise interventions are recommended to help prevent falls and fall-related morbidity in community-dwelling adults aged 65 years and older who are at increased risk of falls, according to a new recommendation statement from the U.S. Preventive Services Task Force (USPSTF) (JAMA. 2024 Jun 4. doi: 10.1001/jama.2024.8481).
Falls remain the leading cause of injury-related morbidity and mortality among older adults in the United States, with approximately 27% of community-dwelling individuals aged 65 years and older reporting at least one fall in the past year, wrote lead author Wanda K. Nicholson, MD, of George Washington University, Washington, and colleagues.
The task force concluded with moderate certainty that exercise interventions yielded a moderate benefit in fall reduction among older adults at risk (grade B recommendation).
The decision to offer multifactorial fall prevention interventions to older adults at risk for falls should be individualized based on assessment of potential risks and benefits of these interventions, including circumstances of prior falls, presence of comorbid medical conditions, and the patient’s values and preferences (grade C recommendation), the authors wrote.
The exercise intervention could include individual or group activity, although most of the studies in the systematic review involved group exercise, the authors noted.
The recommendation was based on data from a systematic evidence review published in JAMA (2024 Jun 4. doi: 10.1001/jama.2024.4166). The task force reviewed data from 83 randomized trials published between January 1, 2016, and May 8, 2023, deemed fair to good quality that examined six types of fall prevention interventions in a total of 48,839 individuals. Of these, 28 studies involved multifactorial interventions and 27 involved exercise interventions.
Overall, multifactorial interventions and exercise interventions were associated with a significant reduction in falls (incidence rate ratio 0.84 and 0.85, respectively).
Exercise interventions were significantly associated with reduced individual risk of one or more falls and injurious falls, but not with reduced individual risk of injurious falls. However, multifactorial interventions were not significantly associated with reductions in risk of one or more falls, injurious falls, fall-related fractures, individual risk of injurious falls, or individual risk of fall-related fractures.
Although teasing out the specific exercise components that are most effective for fall prevention is challenging, the most commonly studied components associated with reduced risk of falls included gait training, balance training, and functional training, followed by strength and resistance training, the task force noted.
Duration of exercise interventions in the reviewed studies ranged from 2 to 30 months and the most common frequency of sessions was 2 to 3 per week.
Based on these findings, the task force found that exercise had the most consistent benefits for reduced risk across several fall-related outcomes. Although individuals in the studies of multifactorial interventions were at increased risk for falls, the multistep process of interventions to address an individual’s multiple risk factors limited their effectiveness, in part because of logistical challenges and inconsistent adherence, the authors wrote.
The results of the review were limited by several factors, including the focus on studies with a primary or secondary aim of fall prevention, the fact that the recommendation does not apply to many subgroups of older adults, and the lack of data on health outcomes unrelated to falls that were associated with the interventions, the authors noted.
The new recommendation is consistent with and replaces the 2018 USPSTF recommendation on interventions for fall prevention in community-dwelling older adults, but without the recommendation against vitamin D supplementation as a fall prevention intervention. The new recommendation does not address vitamin D use; evidence will be examined in a separate recommendation, the task force wrote.
How to Get Older Adults Moving
“The biggest obstacle to exercise is patient inertia and choice to engage in other sedentary activities,” David B. Reuben, MD, and David A. Ganz, MD, both of the University of California, Los Angeles, wrote in an accompanying editorial (JAMA. 2024 Jun 4. doi: 10.1001/jama.2024.9063).
“Given the demonstrated benefits of exercise for cardiovascular disease, cognitive function, and favorable associations with all-cause, cardiovascular, and cancer mortality, specific fall prevention exercise recommendations need to be considered in the context of universal exercise recommendations, including aerobic and muscle strengthening exercise,” the authors wrote. However, maintaining regular exercise is a challenge for many older adults, and more research is needed on factors that drive exercise initiation and adherence in this population, they said.
Multifactorial fall assessments in particular take time, and more fall prevention programs are needed that include multifactorial assessments and interventions, the editorialists said. “Even if primary care clinicians faithfully implement the USPSTF recommendations, a significant reduction in falls and their resulting injuries is still far off,” in part, because of the need for more programs and policies, and the need to improve access to exercise programs and provide insurance coverage for them, they noted.
“Above all, older persons need to be active participants in exercise and reduction of risk factors for falls,” the editorialists concluded.
The research for the recommendation was funded by the Agency for Healthcare Research and Quality (AHRQ). The authors had no financial conflicts to disclose. Dr. Ganz disclosed serving as an author of the 2022 World Guidelines for Falls Prevention and Management for Older Adults.

Half of Family Physicians Feel Their Payment Matches Their Workload
More than half of family physicians think that physicians in general are underpaid, but 50% said that in their own situations, they felt fairly paid given their work demands, based on data from Medscape’s annual Family Physician Compensation Report.
The report, based on data from 7,000 physicians across the United States, showed similarly that 50% of family physicians were happy with their pay, which put them about midway on a list of 29 specialties ranking happiness with pay, above some of the higher paid specialties including orthopedics and plastic surgery.
The report cited data from the Mercer consulting firm showing an increase of 3% in 2023 over 2022 earnings among physicians in the United States overall. The average annual earnings for family medicine physicians were near the bottom of a list of 29 specialties included in the report, but 90% said that potential pay was not a factor or a minor factor in choosing the specialty.
According to the report, 61% of family physicians reported taking no additional work to boost income, but 20% reported taking on additional medical-related work, and 6% reported non-medical-related work.
For most family physicians compensation for patient care remained approximately the same as previous years, and a majority said that neither competing physician practices nor other medical businesses (such as retail clinics or nonphysician practitioners) had an effect on their incomes (70% and 62%, respectively).
Although 54% of family practice physicians reported opportunities for incentive bonuses, these bonuses are generally based on a combination of clinical, economic, and experience factors, and are lower for primary care physicians than for specialists. The average bonus for a primary care physician in 2023 was $27,000 compared with an average bonus of $51,000 for a specialist, according to the report.
Overall, 32% of the family physicians reported gratitude from and relationships with patients as the most satisfying part of their jobs, followed by being good at their jobs by finding answers to medical questions and making diagnoses (24%), and making the world a better place (19%).
Why Money Still Matters
The relatively minor increase in earnings is “the minimum necessary to continue to attract talented individuals into family medicine,” Susan Kuchera, MD, associate director of the Family Medicine Residency Program at Jefferson Health, Abington, Pennsylvania, said in an interview.
The current report referenced a 2023 report of interviews with medical residents, and approximately half of residents overall said that potential earnings were influential in their decisions.
However, the current Medscape report does not reflect the debt burden held by most new physicians, said Dr. Kuchera, who was not involved in the report. “The educational debt and long years of training can be a deterrent for some to choose a lower paying specialty like primary care; if we want to continue to provide our communities with primary care specialists, we need to keep pace with other areas of medicine,” she said.
“It takes a minimum of 7 years to train a primary care physician, we can’t lose sight over time of the factors that impact a person’s choice to pursue primary care,” Dr. Kuchera said.
More Support Needed for Community-Based Care
The data from the report were not surprising, given that the work of primary care physicians is hard, but “historically undervalued” compared with procedural medicine, Dr. Kuchera said. With more emphasis on the value of healthy communities, “we will realize that the relationship family physicians have with their communities is paramount to creating a healthy society,” she added.
The fact that patient care accounts for more than 75% of what family doctors feel to be most rewarding in their profession reflects that most do this work because longitudinal care of patients and communities is rewarding, Dr. Kuchera said in an interview.
“Employers need to value the special training of family doctors to take care of communities,” Dr. Kuchera said. This includes finding ways to incentivize value-based care and to provide the necessary resources to care for communities with poor social determinants of health, she added.
Dr. Kuchera had no financial conflicts to disclose.

The report cited data from the Mercer consulting firm showing an increase of 3% in 2023 over 2022 earnings among physicians in the United States overall. The average annual earnings for family medicine physicians were near the bottom of a list of 29 specialties included in the report, but 90% said that potential pay was not a factor or a minor factor in choosing the specialty.
According to the report, 61% of family physicians reported taking no additional work to boost income, but 20% reported taking on additional medical-related work, and 6% reported non-medical-related work.
For most family physicians compensation for patient care remained approximately the same as previous years, and a majority said that neither competing physician practices nor other medical businesses (such as retail clinics or nonphysician practitioners) had an effect on their incomes (70% and 62%, respectively).
Although 54% of family practice physicians reported opportunities for incentive bonuses, these bonuses are generally based on a combination of clinical, economic, and experience factors, and are lower for primary care physicians than for specialists. The average bonus for a primary care physician in 2023 was $27,000 compared with an average bonus of $51,000 for a specialist, according to the report.
Overall, 32% of the family physicians reported gratitude from and relationships with patients as the most satisfying part of their jobs, followed by being good at their jobs by finding answers to medical questions and making diagnoses (24%), and making the world a better place (19%).
Why Money Still Matters
The relatively minor increase in earnings is “the minimum necessary to continue to attract talented individuals into family medicine,” Susan Kuchera, MD, associate director of the Family Medicine Residency Program at Jefferson Health, Abington, Pennsylvania, said in an interview.
The current report referenced a 2023 report of interviews with medical residents, and approximately half of residents overall said that potential earnings were influential in their decisions.
However, the current Medscape report does not reflect the debt burden held by most new physicians, said Dr. Kuchera, who was not involved in the report. “The educational debt and long years of training can be a deterrent for some to choose a lower paying specialty like primary care; if we want to continue to provide our communities with primary care specialists, we need to keep pace with other areas of medicine,” she said.
“It takes a minimum of 7 years to train a primary care physician, we can’t lose sight over time of the factors that impact a person’s choice to pursue primary care,” Dr. Kuchera said.
More Support Needed for Community-Based Care
The data from the report were not surprising, given that the work of primary care physicians is hard, but “historically undervalued” compared with procedural medicine, Dr. Kuchera said. With more emphasis on the value of healthy communities, “we will realize that the relationship family physicians have with their communities is paramount to creating a healthy society,” she added.
The fact that patient care accounts for more than 75% of what family doctors feel to be most rewarding in their profession reflects that most do this work because longitudinal care of patients and communities is rewarding, Dr. Kuchera said in an interview.
“Employers need to value the special training of family doctors to take care of communities,” Dr. Kuchera said. This includes finding ways to incentivize value-based care and to provide the necessary resources to care for communities with poor social determinants of health, she added.
Dr. Kuchera had no financial conflicts to disclose.
Failed IOL Promotes Poor Maternal and Fetal Outcomes for Mothers With Diabetes
Approximately one-quarter of mothers with diabetes failed induction of labor, and this failure was associated with a range of adverse outcomes for mothers and infants, based on data from more than 2,000 individuals.
Uncontrolled diabetes remains a risk factor for cesarean delivery, Ali Alhousseini, MD, of Corewell Health East, Dearborn, Michigan, and colleagues wrote in a study presented at the annual clinical and scientific meeting of the American College of Obstetricians and Gynecologists.
“Identifying and stratifying associated risk factors for failed induction of labor [IOL] may improve counseling and intrapartum care,” the researchers wrote in their abstract.
The researchers reviewed data from 2,172 mothers with diabetes who underwent IOL at a single university medical center between January 2013 and December 2021. They examined a range of maternal characteristics including age, ethnicity, gestational age, medical comorbidities, insulin administration, parity, and health insurance.
A total of 567 mothers with diabetes (26.1%) failed IOL and underwent cesarean delivery.
Overall, failed IOL was significantly associated with nulliparity (P = .0001), as well as preexisting diabetes compared with gestational diabetes, diabetes control with insulin, maternal essential hypertension, preeclampsia, and polyhydramnios (P = .001 for all). Other factors significantly associated with failed IOL included prenatal diagnosis of fetal growth restriction (P = .008), and placental abnormalities (P = .027).
Neonatal factors of weight, large for gestational age, head circumference, and height were not significantly associated with failed IOL (P > .05 for all).
As for neonatal outcomes, failed IOL was significantly associated with admission to neonatal intensive care unit, hyperbilirubinemia, and longer hospital stay (P = .001 for all). Failed IOL was significantly associated with lower 1-minute APGAR scores, but not with lower 5-minute APGAR scores, the researchers noted (P = .033 for 1-minute score). No association was noted between failed IOL and neonatal readmission, lower umbilical cord pH value, or maternal ethnicity.
The findings were limited by the retrospective design, but data analysis is ongoing, Dr. Alhousseini said. The researchers are continuing to assess the roles not only of optimal glucose control, but other maternal factors in improving maternal and neonatal outcomes, he said.
Data Add to Awareness of Risk Factors
The current study is important because of the increasing incidence of diabetes and the need to examine associated risk factors in pregnancy, Michael Richley, MD, a maternal fetal medicine physician at the University of Washington, Seattle, said in an interview. “The average age of onset of diabetes is becoming younger and type 2 diabetes in pregnancy is an increasingly common diagnosis,” said Dr. Richley, who was not involved in the study.
The increase in both maternal and neonatal adverse outcomes is expected given the risk factors identified in the study, said Dr. Richley. “The patients with diabetes also were sicker at baseline, with hypertensive disorders, growth restriction, and pregestational diabetes,” he noted.
The study findings support data from previous research, Dr. Richley said. The message to clinicians is that patients with diabetes not only have an increased risk of needing a cesarean delivery but also have an increased risk of poor outcomes if a cesarean delivery is needed, he said.
Although a prospective study would be useful to show causality as opposed to just an association, such a study is challenging in this patient population given the limitations of conducting research on labor and delivery, he said.
The study received no outside funding. The researchers and Dr. Richley had no financial conflicts to disclose.

Maternal Buprenorphine Affects Fetal Breathing
Measures of fetal breathing movement were lower in fetuses of pregnant patients who received buprenorphine, compared with controls, based on data from 177 individuals.
The findings were presented at the annual clinical and scientific meeting of the American College of Obstetricians and Gynecologists by Caroline Bulger, MD, of East Tennessee State University, Johnson City.
Pregnant patients with opioid-use disorder in the community surrounding Johnson City receive medication-assisted therapy with buprenorphine during the prenatal period, Dr. Bulger and colleagues wrote in their abstract. The current prenatal program for substance use disorder was established in 2016 based on patient requests for assistance in lowering their buprenorphine dosages during pregnancy, said senior author Martin E. Olsen, MD, also of East Tennessee State University, in an interview.
“Buprenorphine medication–assisted treatment in pregnancy is associated with long-term effects on childhood development such as smaller neonatal brains, decreased school performance, and low birth weight;” however, data on the fetal effects of buprenorphine are limited, said Dr. Olsen.
The current study was conducted to evaluate a short-term finding of the fetal effects of buprenorphine, Dr. Olsen said.
“This study was performed after obstetric sonographers at our institution noted that biophysical profile [BPP] ultrasound assessments of the fetuses of mothers on buprenorphine took longer than for other patients,” said Dr. Olsen.
The researchers conducted a retrospective chart review of 131 patients who received buprenorphine and 46 who were followed for chronic hypertension and served as high-risk controls. Patients were seen at a single institution between July 1, 2016, and June 30, 2020.
The researchers hypothesized that BPP of fetuses in patients receiving buprenorphine might be different from controls because of the effects of buprenorphine.
Overall, patients who received buprenorphine were more likely to have a fetal breathing score of zero than those who underwent a BPP for hypertension. A significant relationship emerged between buprenorphine dosage and breathing motion assessment; patients on high-dose buprenorphine were more likely than patients on low doses to have values of zero on fetal breathing motion assessment, and a chi-squared test yielded a P value of .04269.
The takeaway for clinical practice is that clinicians performing BPP ultrasounds on buprenorphine-exposed fetuses can expect that these assessments may take longer on average than assessments of other high-risk patients, said Dr. Olsen. “Additional assessment after a low BPP score is still indicated for these fetuses just as in other high-risk pregnancies,” he said.
The study was limited primarily by the retrospective design, Dr. Olsen said.
Although current treatment guidelines do not emphasize the effects of maternal buprenorphine use on fetal development, these findings support previous research showing effects of buprenorphine on fetal brain structure, the researchers wrote in their abstract. Looking ahead, “We recommend additional study on the maternal buprenorphine medication–assisted treatment dose effects for fetal and neonatal development with attention to such factors as head circumference, birth weight, achievement of developmental milestones, and school performance,” Dr. Olsen said.
“We and others have shown that the lowest effective dose of buprenorphine can lower neonatal abstinence syndrome/neonatal opioid withdrawal syndrome rates,” but data showing an impact of lowest effective dose management on long-term complications of fetal buprenorphine exposure are lacking, he noted.
The study received no outside funding. The researchers had no financial conflicts to disclose.

LDCT Lung Cancer Screening Finds Undiagnosed Pulmonary Comorbidities in High-Risk Population
Lung cancer screening with low-dose CT (LDCT) can effectively evaluate a high-risk population for undiagnosed chronic obstructive pulmonary disease (COPD) and airflow obstruction, based on data from a new study of approximately 2000 individuals.
Previous research suggests that approximately 70%-90% of individuals with COPD are undiagnosed, especially low-income and minority populations who may be less likely to undergo screening, said Michaela A. Seigo, DO, of Temple University Hospital, Philadelphia, in a study presented at the American Thoracic Society (ATS) 2024 International Conference.
The researchers reviewed data from 2083 adults enrolled in the Temple Healthy Chest Initiative, an urban health system-wide lung cancer screening program, combined with the detection of symptoms and comorbidities.
Baseline LDCT for Identification of Comorbidities
Study participants underwent baseline LDCT between October 2021 and October 2022. The images were reviewed by radiologists for pulmonary comorbidities including emphysema, airway disease, bronchiectasis, and interstitial lung disease. In addition, 604 participants (29%) completed a symptom survey, and 624 (30%) underwent spirometry. The mean age of the participants was 65.8 years and 63.9 years for those with and without a history of COPD, respectively.
Approximately half of the participants in both groups were female.
Overall, 66 of 181 (36.5%) individuals previously undiagnosed with COPD had spirometry consistent with airflow obstruction (forced expiratory volume in 1 second/forced vital capacity, < 70%). Individuals with previously undiagnosed COPD were more likely to be younger, male, current smokers, and identified as Hispanic or other race (not Black, White, Hispanic, or Asian/Native American/Pacific Islander).
Individuals without a reported history of COPD had fewer pulmonary comorbidities on LDCT and lower rates of respiratory symptoms than those with COPD. However, nearly 25% of individuals with no reported history of COPD said that breathing issues affected their “ability to do things,” Ms. Seigo said, and a majority of those with no COPD diagnosis exhibited airway disease (76.2% compared with 84% of diagnosed patients with COPD). In addition, 88.1% reported ever experiencing dyspnea and 72.6% reported experiencing cough; both symptoms are compatible with a clinical diagnosis of COPD, the researchers noted.
“We detected pulmonary comorbidities at higher rates than previously published,” Ms. Seigo said in an interview. The increase likely reflects the patient population at Temple, which includes a relatively high percentage of city-dwelling, lower-income individuals, as well as more racial-ethnic minorities and persons of color, she said.
However, “these findings will help clinicians target the most at-risk populations for previously undiagnosed COPD,” Ms. Seigo said.
Looking ahead, Ms. Seigo said she sees a dominant role for artificial intelligence (AI) in COPD screening. “At-risk populations will get LDCT scans, and AI will identify pulmonary and extra-pulmonary comorbidities that may need to be addressed,” she said.
A combination of symptom detection plus strategic and more widely available access to screening offers “a huge opportunity to intervene earlier and potentially save lives,” she told this news organization.
Lung Cancer Screening May Promote Earlier COPD Intervention
The current study examines the prevalence of undiagnosed COPD, especially among low-income and minority populations, in an asymptomatic high-risk group. “By integrating lung cancer CT screening with the detection of pulmonary comorbidities on LDCT and respiratory symptoms, the current study aimed to identify individuals with undiagnosed COPD,” said Dharani K. Narendra, MD, of Baylor College of Medicine, Houston, in an interview.
“The study highlighted the feasibility and potential benefits of coupling lung cancer screening tests with COPD detection, which is noteworthy, and hits two targets with one arrow — early detection of lung cancer and COPD — in high-risk groups, Dr. Narendra said.
“Although the USPSTF recommends against screening for COPD in asymptomatic patients, abnormal pulmonary comorbidities observed on CT chest scans could serve as a gateway for clinicians to screen for COPD,” said Dr. Narendra. “This approach allows for early diagnosis, education on smoking cessation, and timely treatment of COPD, potentially preventing lung function deterioration and reducing the risk of exacerbations,” she noted.
The finding that one third of previously undiagnosed and asymptomatic patients with COPD showed significant rates of airflow obstruction on spirometry is consistent with previous research, Dr. Narendra told this news organization.
“Interestingly, in questions about specific symptoms, undiagnosed COPD patients reported higher rates of dyspnea, more cough, and breathing difficulties affecting their daily activities, at 16.1%, 27.4%, and 24.5%, respectively, highlighting a lower perception of symptoms,” she said.
“Barriers to lung cancer screening in urban, high-risk communities include limited healthcare facility access, insufficient awareness of screening programs, financial constraints, and cultural or language barriers,” said Dr. Narendra.
Potential strategies to overcome these barriers include improving access through additional screening centers and providing transportation, implementing community-based education and outreach programs to increase awareness about the benefits of lung cancer screening and early COPD detection, and providing financial assistance in the form of free screening options and collaboration with insurers to cover screening expenses, she said.
“Healthcare providers must recognize the dual benefits of lung cancer screening programs, including the opportunity to screen for undiagnosed COPD,” Dr. Narendra emphasized. “This integrated approach is crucial in identifying high-risk individuals who could benefit from early intervention and effective management of COPD. Clinicians should actively support implementing comprehensive screening programs incorporating assessments for pulmonary comorbidities through LDCT and screening questionnaires for COPD symptoms,” she said.
“Further research is needed to evaluate long-term mortality outcomes and identify best practices to determine the most effective methods and cost-effectiveness for implementing and sustaining combined screening programs in various urban settings,” Dr. Narendra told this news organization.
Other areas to address in future studies include investigating specific barriers to screening among different high-risk groups and tailoring interventions to improve screening uptake and adherence, Narendra said. “By addressing these research gaps, health care providers can optimize screening programs and enhance the overall health of urban, high-risk populations,” she added.
The study received no outside funding. The researchers had no financial conflicts to disclose. Dr. Narendra serves on the editorial board of CHEST Physician.

The finding that one third of previously undiagnosed and asymptomatic patients with COPD showed significant rates of airflow obstruction on spirometry is consistent with previous research, Dr. Narendra told this news organization.
“Interestingly, in questions about specific symptoms, undiagnosed COPD patients reported higher rates of dyspnea, more cough, and breathing difficulties affecting their daily activities, at 16.1%, 27.4%, and 24.5%, respectively, highlighting a lower perception of symptoms,” she said.
“Barriers to lung cancer screening in urban, high-risk communities include limited healthcare facility access, insufficient awareness of screening programs, financial constraints, and cultural or language barriers,” said Dr. Narendra.
Potential strategies to overcome these barriers include improving access through additional screening centers and providing transportation, implementing community-based education and outreach programs to increase awareness about the benefits of lung cancer screening and early COPD detection, and providing financial assistance in the form of free screening options and collaboration with insurers to cover screening expenses, she said.
“Healthcare providers must recognize the dual benefits of lung cancer screening programs, including the opportunity to screen for undiagnosed COPD,” Dr. Narendra emphasized. “This integrated approach is crucial in identifying high-risk individuals who could benefit from early intervention and effective management of COPD. Clinicians should actively support implementing comprehensive screening programs incorporating assessments for pulmonary comorbidities through LDCT and screening questionnaires for COPD symptoms,” she said.
“Further research is needed to evaluate long-term mortality outcomes and identify best practices to determine the most effective methods and cost-effectiveness for implementing and sustaining combined screening programs in various urban settings,” Dr. Narendra told this news organization.
Other areas to address in future studies include investigating specific barriers to screening among different high-risk groups and tailoring interventions to improve screening uptake and adherence, Narendra said. “By addressing these research gaps, health care providers can optimize screening programs and enhance the overall health of urban, high-risk populations,” she added.

Lung cancer screening with low-dose CT (LDCT) can effectively evaluate a high-risk population for undiagnosed chronic obstructive pulmonary disease (COPD) and airflow obstruction, based on data from a new study of approximately 2000 individuals.
Previous research suggests that approximately 70%-90% of individuals with COPD are undiagnosed, especially low-income and minority populations who may be less likely to undergo screening, said Michaela A. Seigo, DO, of Temple University Hospital, Philadelphia, in a study presented at the American Thoracic Society (ATS) 2024 International Conference.
The researchers reviewed data from 2083 adults enrolled in the Temple Healthy Chest Initiative, an urban health system-wide lung cancer screening program, combined with the detection of symptoms and comorbidities.
Baseline LDCT for Identification of Comorbidities
Study participants underwent baseline LDCT between October 2021 and October 2022. The images were reviewed by radiologists for pulmonary comorbidities including emphysema, airway disease, bronchiectasis, and interstitial lung disease. In addition, 604 participants (29%) completed a symptom survey, and 624 (30%) underwent spirometry. The mean age of the participants was 65.8 years and 63.9 years for those with and without a history of COPD, respectively.
Approximately half of the participants in both groups were female.
Overall, 66 of 181 (36.5%) individuals previously undiagnosed with COPD had spirometry consistent with airflow obstruction (forced expiratory volume in 1 second/forced vital capacity, < 70%). Individuals with previously undiagnosed COPD were more likely to be younger, male, current smokers, and identified as Hispanic or other race (not Black, White, Hispanic, or Asian/Native American/Pacific Islander).
Individuals without a reported history of COPD had fewer pulmonary comorbidities on LDCT and lower rates of respiratory symptoms than those with COPD. However, nearly 25% of individuals with no reported history of COPD said that breathing issues affected their “ability to do things,” Ms. Seigo said, and a majority of those with no COPD diagnosis exhibited airway disease (76.2% compared with 84% of diagnosed patients with COPD). In addition, 88.1% reported ever experiencing dyspnea and 72.6% reported experiencing cough; both symptoms are compatible with a clinical diagnosis of COPD, the researchers noted.
“We detected pulmonary comorbidities at higher rates than previously published,” Ms. Seigo said in an interview. The increase likely reflects the patient population at Temple, which includes a relatively high percentage of city-dwelling, lower-income individuals, as well as more racial-ethnic minorities and persons of color, she said.
However, “these findings will help clinicians target the most at-risk populations for previously undiagnosed COPD,” Ms. Seigo said.
Looking ahead, Ms. Seigo said she sees a dominant role for artificial intelligence (AI) in COPD screening. “At-risk populations will get LDCT scans, and AI will identify pulmonary and extra-pulmonary comorbidities that may need to be addressed,” she said.
A combination of symptom detection plus strategic and more widely available access to screening offers “a huge opportunity to intervene earlier and potentially save lives,” she told this news organization.
Lung Cancer Screening May Promote Earlier COPD Intervention
The current study examines the prevalence of undiagnosed COPD, especially among low-income and minority populations, in an asymptomatic high-risk group. “By integrating lung cancer CT screening with the detection of pulmonary comorbidities on LDCT and respiratory symptoms, the current study aimed to identify individuals with undiagnosed COPD,” said Dharani K. Narendra, MD, of Baylor College of Medicine, Houston, in an interview.
