ImportanceApproximately 13% of US adults are affected by visual disability, with disproportionately higher rates in groups impacted by certain social determinants of health (SDOH).ObjectiveTo evaluate SDOH associated with severe visual impairment (SVI) to ultimately guide targeted interventions to improve ophthalmic health.Design, Setting, and ParticipantsThis quality improvement study used cross-sectional data from a telephone survey from the Behavioral Risk Factor Surveillance System (BRFSS) that was conducted in the US from January 2019 to December 2020. Participants were noninstitutionalized adult civilians who were randomly selected and interviewed and self-identified as “blind or having serious difficulty seeing, even while wearing glasses.”ExposuresDemographic and health care access factors.Main Outcomes and MeasuresThe main outcome was risk of SVI associated with various factors as measured by odds ratios (ORs) and 95% CIs. Descriptive and logistic regression analyses were performed using the Web Enabled Analysis Tool in the BRFFS.ResultsDuring the study period, 820 226 people (53.07% female) participated in the BRFSS survey, of whom 42 412 (5.17%) self-identified as “blind or having serious difficulty seeing, even while wearing glasses.” Compared with White, non-Hispanic individuals, risk of SVI was increased among American Indian/Alaska Native (OR, 1.63; 95% CI, 1.38-1.91), Black/African American (OR, 1.50; 95% CI, 1.39-1.62), Hispanic (OR, 1.65; 95% CI, 1.53-1.79), and multiracial (OR, 1.33; 95% CI, 1.15-1.53) individuals. Lower annual household income and educational level (eg, not completing high school) were associated with greater risk of SVI. Individuals who were out of work for 1 year or longer (OR, 1.78; 95% CI, 1.54-2.07) or who reported being unable to work (OR, 2.90; 95% CI, 2.66-3.16) had higher odds of SVI compared with the other variables studied. Mental health diagnoses and 14 or more days per month with poor mental health were associated with increased risk of SVI (OR, 1.87; 95% CI, 1.73-2.02). Health care access factors associated with increased visual impairment risk included lack of health care coverage and inability to afford to see a physician.Conclusions and RelevanceIn this study, various SDOH were associated with SVI, including self-identification as being from a racial or ethnic minority group; low socioeconomic status and educational level; long-term unemployment and inability to work; divorced, separated, or widowed marital status; poor mental health; and lack of health care coverage. These disparities in care and barriers to health care access should guide targeted interventions.

IMPORTANCE: Visit adherence has been shown to play a significant role in patient health outcomes. The effect of missing visits on visual acuity (VA) in individuals with neovascular age-related macular degeneration has yet to be characterized. OBJECTIVE: To quantify the association between patients’ adherence to randomized clinical trial visits and VA in individuals with neovascular age-related macular degeneration based on 4 visit adherence metrics. DESIGN, SETTING, AND PARTICIPANTS: This is a secondary analysis of the Comparison of Age-Related Macular Degeneration Treatment Trial randomized clinical trial. Individuals with age-related macular degeneration were recruited from 44 clinical centers in the United States between February 2008 and December 2009. The 2-year study protocol required 1 visit every 4 weeks (every 21-35 days for a total of 26 visits) for monthly vs pro re nata treatments of bevacizumab vs ranibizumab. Analysis took place from November 2018 through May 2019. EXPOSURES: Visit adherence was measured in 4 ways: total number of missed visits, average number of days (avg days) between each visit, longest duration in days (max days) between visits, and visit constancy (the tally of 3-month periods with at least 1 visit attended). Average and max days were also categorized as on time (28-35 days), late (36-60 days), and very late (>60 days). MAIN OUTCOMES AND MEASURES: Change in Early Treatment Diabetic Retinopathy Study VA between the baseline and the last visit. Linear multivariate regression models were applied to analyze the association between visit adherence and change in VA, controlling for age, sex, baseline VA, anti–vascular endothelial growth factor drug, number of injections, and dosing regimen. RESULTS: Of 1178 patients, the mean (SD) age was 79.1 (7.3) years, and 727 (61.7%) were women. The mean (SD) number of missed visits was 2.4 (3.1). Overall, 1091 patients (92.6%) had complete visit constancy during the entire study period. Average days were categorized with 1060 patients (90.0%) classified as on time, 108 (9.2%) were late, and 10 (0.8%) were very late. For max days between visits, 197 patients (16.7%) were on time, 773 (65.6%) were late, and 208 (17.7%) were very late. After controlling for covariates, the late (avg days = −6.1; max days = −2.0) and very late (avg days = −12.5; max days = −5.9) groups saw fewer letters in both the avg and max days categories than patients in the on-time group (P

The Infectious Diseases Society of America recommends ophthalmologic examinations for everyone with positive Candida blood culture results (candidemia) to screen for endophthalmitis, a practice that remains controversial because of multiple concerns for its limited usefulness and potential for harm.To determine guideline efficacy by reconciling discrepancies in the incidence of endophthalmitis and evaluating outcomes of studies assessing ophthalmologic screening for candidemia.PubMed literature searches, including the search terms candidemia, fungemia, chorioretinitis, and endophthalmitis, identified longitudinal studies prior to 2018 of patients who underwent ophthalmologic evaluations in the setting of positive fungal blood culture results regardless of symptoms or clinical status. Additional studies not captured by these queries were found by manually scanning references within the articles captured by the queries. Ambiguous studies of patients with concomitant bacterial or viral infections were excluded.Thirty-eight applicable studies of 7472 patients who underwent ophthalmologic screening for candidemia or fungemia were identified. Criteria were compared with the conventional definition of endophthalmitis based on present (concordant) or absent (discordant) frank vitreous involvement. Concordant (59 of 6693 [0.9%]) and discordant (114 of 779 [14.6%]) endophthalmitis incidence rates differed by 13.8% (95% CI, 11.4%-16.4%; P .001). Visual acuity for each case was recorded verbatim as subjective report provided by each study, when available. None of the concordant endophthalmitis cases reported direct, intraocular, microscopic evidence of Candida or other fungal organisms. Outcomes were available for 19 patients with concordant endophthalmitis; 6 died within 4 weeks of screening. The rate of substantial vision loss was associated (φ = 0.58; 95% CI, 0.01-0.86; P = .046) with additional invasive intervention (3 of 6 [50.0%]) compared with medical management alone (0 of 6).In this systematic review without meta-analysis, inconsistent definitions of endophthalmitis accounted for discrepancies of its incidence and overreporting among patients with candidemia, contributing to bias and resulting in the construction of guidelines. As few as 3 of 7472 patients had potential improvement, while routine examination overall could lead to additional interventions and harm in this population. These findings suggest that indiscriminate screening based on candidemia alone does not appear to be supported by the literature and should be reevaluated for inclusion as a recommendation from the Infectious Diseases Society of America.

Importance Understanding the distribution of patient complaints by physician age may provide insight into common patient concerns characteristic of early, middle, and late stages of careers in ophthalmology. Most previous studies of patient dissatisfaction have not addressed the association with physician age or controlled for other characteristics (eg, practice setting, subspecialty) that may contribute to the likelihood of patient complaints, unsafe care, and lawsuits. Objective To assess the association between ophthalmologist age and the likelihood of generating unsolicited patient complaints (UPCs) among a cohort of ophthalmologists. Design, Setting, and Participants Retrospective cohort study with variable duration of follow-up. The study assessed time to first complaint between 2002 and 2015 in 1342 attending ophthalmologists or neuro-ophthalmologists who had graduated from medical school before 2010 and were affiliated with an organization that participates in Vanderbilt University Medical Center’s Patient Advocacy Reporting System. Participants were stratified into 5 age bands and were followed up from the time of their employment to receipt of their first complaint. Trained coders categorized UPCs into 34 specific types under 6 major categories. Main Outcomes and Measures Time to first recorded complaint. Multivariable Cox proportional hazards model was used to measure the association between time to first complaint and ophthalmologist age after adjustment for predetermined covariates. Results The median physician age was 47 years, with 9% who were 71 years or older. The cohort was 74% male, 90% held MD degrees, and 73% practiced in academic medical centers. The mean follow-up period was 9.8 years. Ophthalmologists older than 70 years had the lowest complaint rate (0.71 per 1000 follow-up days vs 1.41, 1.84, 2.02, and 1.88 in descending order of age band). By 2000 days of follow-up (or within 5.5 years), the youngest group had an estimated UPC risk of 0.523. By 4000 days (>10 years), participants in the older than 70 years age band had an estimated risk of UPC of only 0.364. The 2 youngest age bands were associated with a statistically significant shorter time to first complaint. Compared with those aged 71 years or older, the risk of incurring a UPC for those aged 41 to 50 years was 1.73-fold higher (hazard ratio [HR], 1.73; 95% CI, 1.21-2.46;P = .002). Similarly, participants aged 31 to 40 years had a 2.36 times higher risk of incurring a UPC (HR, 2.36; 95% CI, 1.64-3.40;P Conclusions and Relevance This study suggests that older ophthalmologists are less likely to receive UPCs than younger ones. Although limitations in the study design could affect the interpretation of these conclusions, the findings may have practical implications for patient safety, clinical education, and clinical practice management.

Importance The frequency of anti–vascular endothelial growth factor (VEGF) injections has grown exponentially with the introduction of bevacizumab, ranibizumab, and most recently aflibercept. The cost associated with these medications has garnered significant national attention, warranting a granular analysis of their use. Objective To analyze trends in anti-VEGF injections for US Medicare Part B beneficiaries from 2012 to 2015. Design, Setting, and Participants This observational cohort study used 2012-2015 data from the Centers for Medicare & Medicaid Services Medicare Part B Provider Utilization Files to analyze trends in intravitreal injections of anti-VEGF medications among Medicare Part B beneficiaries and their health care professionals. Main Outcomes and Measures The primary outcome measure was distribution of and change over time in the number of anti-VEGF injections performed for ranibizumab, aflibercept, and bevacizumab. Results A total of 2 574 124 intravitreal injections were performed by 3348 ophthalmologists in the outpatient setting for Medicare Part B beneficiaries during the 2015 calendar year; 100 ophthalmologists (3.0%) performed the highest volume of intravitreal injections. The total number of intravitreal injections administered in 2015 was 870 843 for aflibercept, 697 412 for ranibizumab, and 1 147 432 for bevacizumab. Ranibizumab injections decreased by 7.1% from 2012 to 2015 and bevacizumab injections decreased by 17.1%. From 2013 to 2015, aflibercept injections increased by 69.4%. The 100 ophthalmologists performing the highest volume of ranibizumab injections, as gauged by number of injections administered, accounted for 31.0% (95% CI, 30.994%-30.997%) of all ranibizumab injections nationally. The 100 ophthalmologists performing the highest volume of aflibercept injections accounted for 17.6% (95% CI, 17.638%-17.641%) of all aflibercept injections and the 100 ophthalmologists performing the highest volume of bevacizumab injections accounted for 19.6% (95% CI, 19.649%-19.653%) of all bevacizumab injections administered nationally to Medicare Part B beneficiaries. The highest number of injections per 1000 Medicare Part B beneficiaries occurred in Nebraska (aflibercept), Tennessee (ranibizumab), and South Dakota (bevacizumab). Conclusions and Relevance A total of 3.0% of ophthalmologists account for 17.6% to 31.0% of the total number of anti-VEGF injections administered nationally in the Medicare Part B population. Overall, bevacizumab and ranibizumab injections have decreased, coinciding with a 69.4% increase in aflibercept injections.
