Opioid Prescription Trends Among Sleep Surgeons in the United States.

OBJECTIVE: This study aimed to describe trends in opioid prescriptions among US sleep surgeons between 2013 and 2021 via a retrospective analysis conducted using publicly available data. METHODS: Utilizing the CMS part D database, we analyzed data from 82 sleep surgeons, focusing on metrics including number of opioid beneficiaries and claims, opioid cost, and opioid day supply per beneficiary. We employed statistical methods including ANOVA, t-tests, Fisher's exact test with Monte Carlo Simulation, and regression models. RESULTS: There were no significant changes in the number of opioid claims (p = 0.782) or beneficiaries per provider (p = 0.590) nor was there a decrease in opioid day supply per beneficiary (p = 0.489) over time. Surgeons who graduated residency before 2000 prescribed significantly more opioids over the course of the study period compared to those graduating after 2000 with higher opioid day supply per beneficiary (13.34 vs. 7.42, p < 0.001), higher opioid beneficiaries per provider (21.62 vs. 19.36, p = 0.028), and higher opioid claims per provider (30.30 vs. 21.78, p < 0.001). A significant annual decrease in opioid cost per beneficiary (ANOVA, p = 0.006) was noted. CONCLUSIONS: This study illuminates a significant impact of provider years in practice on opioid prescribing trends, alongside a decreasing trend in opioid cost per beneficiary. Despite the evolving paradigm emphasizing opioid reduction and evidence of decreasing opioid prescriptions in other otolaryngology subspecialties, our findings depict that opioid prescriptions among sleep surgeons remained stable from 2013 to 2021.

Sociodemographic and Healthcare System Barriers to PAP Alternatives for Adult OSA: A Scoping Review.

OBJECTIVE: To investigate sociodemographic and healthcare system barriers to access and utilization of alternative treatments to positive airway pressure (PAP) in the management of adult obstructive sleep apnea (OSA). DATA SOURCES: PubMed, Embase, and Web of Science databases were searched from 2003 to 2023 for English-language studies containing original data on sociodemographic and healthcare system barriers to PAP-alternative treatments for adult OSA. REVIEW METHODS: Studies were assessed using the Preferred Reporting Items for Systematic Reviews and Meta-analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines. Title and abstract screening, full-text review, and data collection were conducted by two investigators independently. RESULTS: Out of 1,615 studies screened, 13 studies met inclusion criteria and reported on a total of 1,206,115 patients who received PAP alternative treatments, including surgery (n = 9 studies), and oral appliances (OAs) (n = 3 studies). The chance of receiving a PAP-alternative treatment such as surgery was greater among patients aged 39 years or younger, had body mass index below 30 kg/m2, fewer comorbidities, private insurance, and a higher occupational and income status. The decision of individuals to receive PAP alternative treatments was influenced by increased patient education from providers, as well as improvements in daytime sleepiness and partner perception of snoring and apnea. CONCLUSION: Cumulative evidence suggests that several sociodemographic and healthcare system factors are associated with decreased use of PAP alternatives when PAP therapy fails. Investigation of interventions to eliminate these potential barriers may improve access and treatment outcomes. Laryngoscope, 2024.

Needs assessment for direct ophthalmoscopy training in neurology residency.

BACKGROUND: Assessment of the ocular fundus, traditionally by direct ophthalmoscopy (DO), is essential to evaluate many neurologic diseases. However, the status of DO training in neurology residencies is unknown. We conducted a needs assessment to determine current attitudes, curricula, and gaps in DO training. METHODS: A survey was developed and administered to residents and program directors (PDs) at ACGME accredited neurology residencies in the United States. The survey assessed factors such as current DO curricula, perceived importance of DO, confidence of skills, and need for improvement. Data analysis was performed using the Mann Whitney U test and Fisher Exact Test. RESULTS: Nineteen PDs (11.6%) and 74 (41.1%) residents responded to the survey. 97.1% of residents and 100.0% of PDs believe DO is an important skill to learn. 29.4% of PDs expected graduating residents to have completed > 10 supervised DO exams, while 0.0% of graduating fourth year residents reported doing so (p = 0.03). 35.7% of graduating residents had never correctly identified an abnormal finding on DO. The number of times residents practiced DO unsupervised correlated with increasing confidence in all components of the DO exam (p < 0.05). Residents who felt their program emphasized DO were more likely to perform DO at least once a week compared to residents who did not perceive program emphasis (61.9% vs. 35.0%, p = 0.02) and were more confident in DO (p < 0.05). 66.7% of residents and 42.1% of PDs were not satisfied with current levels of DO training. 96.7% of residents and 78.9% of PDs felt it was important to improve curriculum for DO training. Supervised practice and practice skills sessions were identified as the most helpful interventions to improve DO training. CONCLUSIONS: The vast majority of neurology PDs and residents believe DO is an important skill to learn, are unsatisfied with the current level of DO training, and advocate for improvement in DO curricula. Current DO curricula have limited formal didactic training and supervised practice. The bulk of DO learning occurs through unsupervised practice, which is influenced by motivational factors such as perceived residency emphasis on DO learning.

METformin for the MINimization of Geographic Atrophy Progression (METforMIN): A Randomized Trial.

Purpose: Metformin use has been associated with a decreased risk of age-related macular degeneration (AMD) progression in observational studies. We aimed to evaluate the efficacy of oral metformin for slowing geographic atrophy (GA) progression. Design: Parallel-group, multicenter, randomized phase II clinical trial. Participants: Participants aged ≥ 55 years without diabetes who had GA from atrophic AMD in ≥ 1 eye. Methods: We enrolled participants across 12 clinical centers and randomized participants in a 1:1 ratio to receive oral metformin (2000 mg daily) or observation for 18 months. Fundus autofluorescence imaging was obtained at baseline and every 6 months. Main Outcome Measures: The primary efficacy endpoint was the annualized enlargement rate of the square root-transformed GA area. Secondary endpoints included best-corrected visual acuity (BCVA) and low luminance visual acuity (LLVA) at each visit. Results: Of 66 enrolled participants, 34 (57 eyes) were randomized to the observation group and 32 (53 eyes) were randomized to the treatment group. The median follow-up duration was 13.9 and 12.6 months in the observation and metformin groups, respectively. The mean ± standard error annualized enlargement rate of square root transformed GA area was 0.35 ± 0.04 mm/year in the observation group and 0.42 ± 0.04 mm/year in the treatment group (risk difference = 0.07 mm/year, 95% confidence interval = -0.05 to 0.18 mm/year; P = 0.26). The mean ± standard error decline in BCVA was 4.8 ± 1.7 letters/year in the observation group and 3.4 ± 1.1 letters/year in the treatment group (P = 0.56). The mean ± standard error decline in LLVA was 7.3 ± 2.5 letters/year in the observation group and 0.8 ± 2.2 letters/year in the treatment group (P = 0.06). Fourteen participants in the metformin group experienced nonserious adverse events related to metformin, with gastrointestinal side effects as the most common. No serious adverse events were attributed to metformin. Conclusions: The results of this trial as conducted do not support oral metformin having effects on reducing the progression of GA. Additional placebo-controlled trials are needed to explore the role of metformin for AMD, especially for earlier stages of the disease.

Comparison of Three Handheld Fundus Cameras for Assessment of the Vertical Cup-To-Disk Ratio.

Purpose To compare the quality of optic nerve photographs from three different handheld fundus cameras and to assess the reproducibility and agreement of vertical cup-to-disk ratio (VCDR) measurements from each camera. Methods Adult patients from a comprehensive ophthalmology clinic and an intravitreous injection clinic in northern Thailand were recruited for this cross-sectional study. Each participant had optic nerve photography performed with each of 3 handheld cameras: the Volk iNview, Volk Pictor Plus, and Peek Retina. Images were graded for VCDR in a masked fashion by two photo-graders and images with > 0.2 discrepancy in VCDR were assessed by a third photo-grader. Results A total of 355 eyes underwent imaging with three different handheld fundus cameras. Optic nerve images were judged ungradable in 130 (37%) eyes imaged with Peek Retina, compared to 36 (10%) and 55 (15%) eyes imaged with the iNview and Pictor Plus, respectively. For 193 eyes with gradable images from all 3 cameras, inter-rater reliability for VCDR measurements was poor or moderate for each of the cameras, with intraclass correlation coefficients ranging from 0.41 to 0.52. A VCDR ≥ 0.6 was found in 6 eyes on iNview images, 9 eyes on Pictor Plus images, and 3 eyes on Peek images, with poor agreement between cameras (e.g., no eyes graded as VCDR ≥ 0.6 on images from both the iNview and Pictor Plus). Conclusions Inter-rater reliability of VCDR grades from 3 handheld cameras was poor. Cameras did not agree on which eyes had large VCDRs.

Outcomes After Selective Fasciotomy for Revascularization of Nontraumatic Acute Lower Limb Ischemia.

Objectives: Limited data support the use of fasciotomies in acute limb ischemia (ALI) in patients with isolated arterial occlusion. This study describes an experience in which fasciotomies are not regularly performed post-revascularization. Methods: Using International Classification of Diseases, Ninth and Tenth Edition codes, patients presenting to the University of California Davis Medical Center between January 2003 and July 2018 with ALI, excluding those with traumatic injuries were identified. The primary outcome was major amputation, and the secondary outcome was foot drop. Additionally, the characteristics of those patients in each category of ischemic severity excluding those with grade 3 ischemia were summarized. Results: Of the 253 patients identified, revascularization was successful in 230 patients with 11 total fasciotomies performed. One hundred thirty-five patients were Rutherford Class 1/2A and 95 were 2B. In those with 1/2A ischemia, 134 (102 had >6 hours of symptoms) did not undergo fasciotomy with only one amputation occurring in this group. In those with 2B ischemia, 65 had >6 hours of symptoms; 58 did not undergo fasciotomy with 4 major amputations. In the 30 patients with ≤6 hours of ischemic symptoms, 27 did not undergo fasciotomy with 1 major amputation occurring in this group. There were no amputations in those patients who underwent fasciotomies. Additionally, there were 14 patients with a foot drop, of which 11 were in patients with 2B ischemia without fasciotomy. Conclusions: The data suggest that regardless of ischemic duration, 1/2A patients may not need fasciotomies, while those patients with 2B ischemia may benefit.
