Importance: Primary care professionals (PCPs) have a central role in screening for diabetic retinopathy (DR), especially in settings where access to specialty eye care is limited. Data on current DR screening practice patterns in primary care are needed to inform screening strategies., Objectives: To assess the practice patterns of fundoscopic examination for DR screening in a large primary care network and to evaluate the sensitivity and accuracy of PCP fundoscopy for detecting DR., Design, Setting, and Participants: A retrospective cohort study was performed using random sampling and manual review of electronic health records of PCP fundoscopic examination documentation compared with documentation of an examination performed by an eye care professional (ophthalmologist or optometrist) within 2 years before or after primary care encounters. From a single-institution primary care network of 28 clinics, 7449 adult patients with diabetes seen at least once in the primary care network in 2019 were eligible for this study. Data from 2001 encounters were abstracted from the electronic health record for a random sample of 767 patients. Data analysis was performed from January 2021 to May 2022., Exposure: Fundoscopic examination by PCPs., Main Outcomes and Measures: The frequency of PCPs performing fundoscopy at least once in the calendar year for patients with diabetes. Univariate and multivariable logistic regression analyses were performed to identify patient, clinician, and clinic factors associated with PCPs performing fundoscopy at least once in the calendar year. The PCP examination results were compared with diagnoses made by eye care professionals to assess the sensitivity and accuracy of the findings from PCP examinations., Results: Among the 767 adult patients with diabetes included in the analysis, 387 (50.5%) were female, and the median age was 64 years (IQR, 54-71 years). Primary care professionals documented a fundoscopic examination for 93 patients (12.1%); all results were documented as normal. When eye care professional examination results were used as the reference standard, the accuracy of PCP fundoscopic examination was 62.7% (95% CI, 50.0%-73.9%) and sensitivity for detecting disease was 0.0% (95% CI, 0.0%-14.9%). No patient demographic or clinical characteristics were associated with PCPs performing fundoscopy. In multivariable logistic regression, the number of PCP years in practice was associated with greater odds of patients receiving fundoscopy at least once in the year (adjusted odds ratio per 10 years in practice, 1.26; 95% CI, 1.01-1.59; P = .04); having nurse practitioner credentials was associated with lower odds of receiving fundoscopy (adjusted odds ratio, 0.23; 95% CI, 0.04-0.79; P = .049; compared with having physician credentials); after adjusting for rural clinic location, clinic location in a primary care shortage area, and documentation of an up-to-date eye care professional examination by a PCP in the study year., Conclusions and Relevance: In this cohort study, fundoscopic examination was rarely performed and was not sensitive for detecting DR in primary care practice. Because the rate of DR screening by eye care professionals remains low, research to explore and break down barriers to the implementation of effective primary care-based DR screening strategies, such as teleretinal imaging, is needed to prevent vision loss from undiagnosed DR.

Background: Early detection of ophthalmic conditions such as diabetic retinopathy (DR) and glaucoma is crucial to preventing vision loss. Previous studies have evaluated teleretinal screening programs for DR in well-insured populations. The purpose of this retrospective study was to evaluate a teleretinal screening program in a population of uninsured and underinsured patients seen in a Federally Qualified Health Center (FQHC). Methods: We conducted a retrospective chart review of patients (age ≥ 18) who underwent teleretinal imaging (TRI) at a FQHC between January 2015 and September 2019. TRI gradings and patient demographic and clinical information were abstracted. Factors associated with referral for a dilated eye exam by an ophthalmologist, adherence to recommended follow-up dilated eye exam, and ophthalmology visit attendance were examined. Results: 3130 TRIs were graded in 2216 eyes (1107 patients). 65.2% (N = 722) self-identified as Hispanic and 56.3% (N = 623) required interpreter services. Follow-up dilated fundus examination (DFE) was recommended for 388 TRIs, 49% (N = 190) of which were completed within 1 year. Adherence to the recommended ophthalmology exam was not associated with any baseline clinical or demographic characteristics (p > 0.05). Older age, male sex, hypertension, proteinuria, and higher A1c were significantly associated with greater odds of ophthalmology referral based on TRI (all p < 0.05), after adjusting for covariates. Less severe diabetic retinopathy, no insurance coverage, and Hispanic ethnicity were associated with lower odds of attending an ophthalmology visit, regardless of follow-up recommendations based on TRI (all p < 0.05). Conclusion: In an FQHC serving predominantly uninsured and underinsured patients, only 49% of recommended DFE were completed within one year. Less severe diabetic retinopathy, lack of insurance coverage, and Hispanic ethnicity were associated with a lower likelihood of having a DFE regardless of recommendation. These results suggest that greater system-level efforts are needed to increase adherence to follow-up eye exams after TRI to ensure sight-saving care for underserved populations.
