Self-reported healthcare utilization by adults with diabetic retinopathy in the United States

Social Determinants of Health Data Availability for Patients with Eye Conditions

Purpose

To quantify and characterize social determinants of health (SDoH) data coverage using single-center electronic health records (EHRs) and the National Institutes of Health All of Us research program.

Design

Retrospective cohort study from June 2014 through June 2021.

Participants

Adults 18 years of age or older with a diagnosis of diabetic retinopathy, glaucoma, cataracts, or age-related macular degeneration.

Methods

For All of Us, research participants completed online survey forms as part of a nationwide prospective cohort study. In local EHRs, patients were selected based on diagnosis codes.

Main Outcome Measures

Social determinants of health data coverage, characterized by the proportion of each disease cohort with available data regarding demographics and socioeconomic factors.

Results

In All of Us, we identified 23 806 unique adult patients, of whom 2246 had a diagnosis of diabetic retinopathy, 13 448 had a diagnosis of glaucoma, 6634 had a diagnosis of cataracts, and 1478 had a diagnosis of age-related macular degeneration. Survey completion rates were high (99.5%-100%) across all cohorts for demographic information, overall health, income, education, and lifestyle. However, health care access (12.7%-29.4%), housing (0.7%-1.1%), social isolation (0.2%-0.3%), and food security (0-0.1%) showed significantly lower response rates. In local EHRs, we identified 80 548 adult patients, of whom 6616 had a diagnosis of diabetic retinopathy, 26 793 had a diagnosis of glaucoma, 40 427 had a diagnosis of cataracts, and 6712 had a diagnosis of age-related macular degeneration. High data coverage was found across all cohorts for variables related to tobacco use (82.84%-89.07%), alcohol use (77.45%-83.66%), and intravenous drug use (84.76%-93.14%). However, low data coverage (< 50% completion) was found for all other variables, including education, finances, social isolation, stress, physical activity, food insecurity, and transportation. We used chi-square testing to assess whether the data coverage varied across different disease cohorts and found that all fields varied significantly (P < 0.001).

Conclusions

The limited and highly variable data coverage in both local EHRs and All of Us highlights the need for researchers and providers to develop SDoH data collection strategies and to assemble complete datasets.

Evaluation of educational interventions on eye health for dietetic and pharmacy professions: a pre-post study

BACKGROUND

We piloted an educational intervention that aimed to enhance awareness about nutrition-age-related macular degeneration (AMD) links among practising and student dietitians then expanded the scope of this intervention to include general eye health, which was delivered to pharmacy students.

METHODS

A pilot intervention was conducted in 2019 at the Dietitians Australia Conference (Gold Coast, Australia) where practising and student dietitians underwent a 2-hour small group educational workshop on nutrition and AMD links. Pre-post questionnaires were administered to participants, with voluntary completion of both questionnaires an indicator of consent to participate in the intervention. The primary intervention outcome was a change in AMD-related nutrition knowledge pre-post intervention. A larger intervention was then conducted at the University of Sydney (Sydney, Australia) where pharmacy students underwent a 4-hour educational module to improve general eye health knowledge, as well as student perceptions and attitudes towards a pharmacists' role in low vision care. Similarly, pre-post questionnaires were administered, with voluntary completion of both questionnaires an indicator of consent to participate in the intervention. The primary intervention outcomes were changes in total knowledge, total perception and total attitude scores pre-post intervention.

RESULTS

(1) Among 10 accredited and 5 student dietitians, there was significant overall knowledge improvement (mean pre-post score: 7.07 ± 1.94 vs. 10.8 ± 1.01, p = 0.001) specifically around appropriate dietary advice, food sources of key AMD-related nutrients, and awareness of supplements. (2) Among 179 second-year pharmacy students enrolled in the 'Pharmacy Practice' Unit of Study (Bachelor of Pharmacy, University of Sydney), total eye health knowledge (6.25 ± 1.93 vs. 6.64 ± 2.0; p = 0.011) significantly improved, along with total perception scores (41.54 ± 5.26 vs. 42.45 ± 4.95; p = 0.004). Total attitude scores were not significantly different.

CONCLUSIONS

The pilot intervention improved relevant nutrition-AMD knowledge among practising/student dietitians. The modified intervention for pharmacy students also significantly improved general eye health knowledge as well as students' perception of a pharmacists' role in low vision care.

Impact and Characterization of Delayed Pan-Retinal Photocoagulation in Proliferative Diabetic Retinopathy

PURPOSE

The American Academy of Ophthalmology recommends that patients diagnosed with proliferative diabetic retinopathy (PDR) be considered for pan-retinal photocoagulation (PRP) treatment within 1 month of diagnosis. This study aimed to investigate the effect delayed treatment had on visual outcomes and to characterize the medical and socioeconomic factors that contributed to delayed treatment of PDR.

DESIGN

Retrospective clinical study.

METHODS

This study examined 259 patients diagnosed with PDR and treated with PRP from 2015 to the present. Visual acuity (VA) outcomes through 24 months were compared among patients treated the day of diagnosis, and at 1-14 days, 14-31 days, and >31 days post-treatment. The relationships between time to treatment (days between PDR diagnosis and PRP) and medical comorbidities (coronary artery disease and/or myocardial infarction, heart failure, chronic kidney disease, dialysis, stroke, inpatient admission), laboratory values (hemoglobin A_1c, blood urea nitrogen, serum creatinine), and socioeconomic factors (health insurance, median household income of ZIP code, and distance from ZIP code to treatment site) were examined.

RESULTS

Mean time to treatment for all patients was 27.8 ± 41.4 days. VA was significantly decreased in patients who received PRP after 31 days compared with those treated on the day of diagnosis at 12 (P < .001) and 24 (P = .03) months post-treatment. Inpatient admission between diagnosis and treatment was significantly associated with an increase in time to treatment (86.5 ± 50.2 days; P < .001).

CONCLUSIONS

In patients with diagnosed PDR, a delay in PRP treatment beyond 31 days was associated with worse visual outcomes than those treated earlier. Hospital admissions significantly delayed PRP delivery.

Variability in preventive care practices among US adults with diabetes mellitus

INTRODUCTION

Patients with diabetes are advised to follow standard medical care including daily blood glucose and foot checks, eye examinations with pupil dilation, and cholesterol checks to prevent diabetes-related complications. It is unclear how these practices currently vary across different US population subgroups. The objective of this study was to assess variation in overall and individual diabetes care practices and identify specific factors associated with differences in these practices in a representative sample of US diabetic adults.

RESEARCH DESIGN AND METHODS

Cross-sectional data were from the 2017 Behavioral Risk Factor Surveillance System. Survey logistic regression was used to account for the complex sampling design.

RESULTS

Among 30 780 eligible participants, 8957 (equivalent to 28% of the target population) followed all four diabetes care practices. Insulin-dependent participants had higher adjusted odds (adjusted OR=2.95; 95% CI 2.62 to 3.31) of following all four diabetic care practices compared with those who did not. Cost-related variables (having healthcare coverage and/or a personal doctor) were positively associated with diabetes care practices, with the strongest association observed for adherence to more costly practices (annual eye examination and cholesterol check) versus less costly ones (daily blood glucose check, daily foot check).

CONCLUSIONS

Our findings suggest the need for diabetes care practice-specific and population subgroup-specific public health interventions to encourage early adherence to diabetic care practices and reduce complications.

<p>Self-Reported Awareness of Retinopathy Severity in Diabetic Patients</p>

Background

Diabetic retinopathy (DR) may be asymptomatic in both mild and advanced stages. A patient’s accurate perception of their DR severity may therefore be critical for effective self-management behaviors and understanding the need for timely intervention and follow-up.

Purpose

To evaluate the relationship between self-reported and actual retinopathy severity in diabetic patients.

Methods

This study was a single-center cross-sectional survey. Diabetic patients identified by enterprise data warehouse were sent an online questionnaire where they were asked to self-assess for presence of DR and grade their severity. Actual DR grading was determined via chart review. The primary outcome measures were patient-assessed DR severity and agreement with actual DR severity.

Results

Of 3208 invitations sent, 324 (10%) patients responded and 319 responses were analyzed. The data showed that 39 of 253 (15%) with no DR, 26 of 40 (65%) with mild/moderate DR, and 24 of 26 (92%) with severe DR believed they had DR (p<0.001). Of those with no DR, 214 of 253 (85%) accurately assessed absence of DR. Of those with mild/moderate DR, 25 of 40 (63%) accurately assessed their severity, 14 of 40 (35%) believed they had no DR, and 1 of 40 (3%) believed they had severe DR. In patients with severe DR, 9 of 26 (35%) correctly assessed their severity, 15 of 26 (58%) believed they had mild/moderate DR, and 2 of 26 (8%) believed they had no DR.

Conclusion

Patients with severe DR were the most likely to report presence of DR, but often underestimated their disease severity. Many with mild/moderate DR did not realize they had DR. This consistent underestimation of severity across all a significant barrier to timely follow-up and treatment necessary to prevent future visual impairment.

Community Health Centers: A Model for Integrating Eye Care Services with the Practice of Primary Care Medicine

SIGNIFICANCE

Optometry is desperately needed to combat the increasing rate of avoidable visual impairment that goes undiagnosed largely owing to the lack of integration of eye care services with primary care medicine. Government leaders are actively discussing substantive changes to health care legislation that will impact optometrists and their patients. The importance of a regular eye examination for disease prevention has long been undervalued in the setting of primary care. Consequently, many serious and potentially treatable ocular and systemic diseases go undiagnosed. Despite clear indicators that vision impairment increases the risk of morbidity and mortality from chronic systemic disease and decreases quality of life, vision health remains among the greatest unmet health care needs in the United States. To improve vision care services for all Americans, we must focus our attention on two central themes. First, we must educate the public, health care professionals, and policymakers on the importance of routine eye care as a preventive measure in the setting of primary care. Next, we need to recognize that optometrists, through their geographic distribution and advanced training, are in a strategic position to deliver integrated, comprehensive, cost-effective eye care services for individuals most in need. In this perspective, we discuss a model for integrating optometric services with the practice of primary care medicine to facilitate early detection of both eye and systemic disease while reducing serious and preventable health-related consequences.

Self-reported Eye Care Use Among US Adults Aged 50 to 80 Years

Importance

Contemporary data on use of eye care by US adults are critical, as the prevalence of age-related eye disease and vision impairment are projected to increase in the coming decades.

Objectives

To provide nationally representative estimates on self-reported use of eye care by adults aged 50 to 80 years, and to describe the reasons that adults do and do not seek eye care.

Design, Setting, and Participants

The National Poll on Healthy Aging, a cross-sectional, nationally representative online survey was conducted from March 9 to 24, 2018, among 2013 individuals aged 50 to 80 years.

Main Outcomes and Measures

The proportion of US adults who received an eye examination within the past 2 years as well as the sociodemographic and economic factors associated with receipt of eye care.

Results

Among 2013 adults aged 50 to 80 years (survey-weighted proportion of women, 52.5%; white non-Hispanic, 71.1%; mean [SD] age, 62.1 [9.0] years), the proportion reporting that they underwent an eye examination in the past year was 58.5% (95% CI, 56.1%-60.8%) and in the past 2 years was 82.4% (95% CI, 80.4%-84.2%). Among those with diabetes, 72.2% (95% CI, 67.2%-76.8%) reported undergoing an eye examination in the past year and 91.3% (95% CI, 87.7%-93.9%) in the past 2 years. The odds of having undergone an eye examination within the past 2 years were higher among women (adjusted odds ratio [AOR], 2.00; 95% CI, 1.50-2.67), respondents with household incomes of $30 000 or more (AOR, 1.57; 95% CI, 1.08-2.29), and those with a diagnosed age-related eye disease (AOR, 3.67; 95% CI, 2.37-5.69) or diabetes (AOR, 2.30; 95% CI, 1.50-3.54). The odds were lower for respondents who were unmarried (AOR, 0.71; 95% CI, 0.53-0.96), from the Midwest (AOR, 0.55; 95% CI, 0.34-0.87) or West (AOR, 0.60; 95% CI, 0.38-0.94), or reported fair or poor vision (AOR, 0.43; 95% CI, 0.28-0.65). Reasons reported for not undergoing a recent eye examination included having no perceived problems with their eyes or vision (41.5%), cost (24.9%), or lack of insurance coverage (23.4%).

Conclusions and Relevance

In this study, the rate of eye examinations was generally high among US adults aged 50 to 80 years, yet there were several significant demographic and socioeconomic differences in the use of eye care. These findings may be relevant to health policy efforts to address disparities in eye care and to promote care for those most at risk for vision problems.

Does patient education improve compliance to routine diabetic retinopathy screening?

Introduction

Diabetic retinopathy (DR) screening relies on adherence to follow-up eye care. This article assesses if a model of patient education and tele-retina screening among high-risk patients with DR can achieve increased rates of compliance within a one-year follow-up.

Methods

Between May 2014 and May 2016, DR screening was conducted in a cohort of 101 patients with diabetes in Southern Ontario. Optical coherence tomography and fundus photography images were used to visualize the retina remotely. Enrolled patients participated in an educational seminar at the screening site with the expressed purpose of enhancing patient understanding of DR. A chi-squared test was used to assess patient compliance to follow-up examinations within 6–12 months, while pre-to post-screening HbA1c levels were compared using a dependent t-test.

Results

Of 101 patients who completed the study, 33 patients (32.6%) have never previously been screened for DR. Baseline compliance to annual screening increased from 36 patients (35.6%) to 51 patients (50.5%) after the tele-retina programme ( p = 0.03). Eighty-nine patients (88%) were referred to an optometrist for ongoing care compared with 12 patients (11.9%) to an ophthalmologist for management of DR. Overall, 100 patients (99.0%) were satisfied with the tele-retina screening. There was no significant change in pre- to-post screening HbA1c levels ( p = 0.91).

Discussion

Patient education-focused tele-retina screening for DR significantly increased compliance to follow-up in a high-risk, non-compliant patient population. Management of diabetes as captured by HbA1c levels remain unchanged in the cohort indicating a need for ongoing inter-professional collaboration in education and vision screening.
