Adherence of those with Self-reported Glaucoma in the United States to Eye Examination Visits
Hou CH; Shih SF; Pu CJournal of Glaucoma 2023; 32: 885-890
PRECIS: The adherence of American patients with self-reported glaucoma to the follow-up recommendations is extremely low. Estimated adherence rate is lower than that obtained by previous studies that did not use a U.S. nationally representative sample. PURPOSE: To evaluate adherence to ophthalmic outpatient follow-up visits and vision examinations in the American population aged 40 years or above. METHODS: The percentage of American patients aged 40 years or above who adhered to glaucoma treatment guidelines was estimated using 2015-2019 Medical Expenditure Panel Survey (MEPS) data. Adherence was defined according to the International Council of Ophthalmology guidelines. We also compared individuals with and without self-reported glaucoma who have made at least one ophthalmic outpatient visit and at least one vision examination visit within a year. Differences in means and percentages were estimated to account for the covariance due to the complex sampling design and using Taylor series linearization. RESULTS: Approximately 4.4 million people aged over 40 years had self-reported glaucoma in 2019 (3.21%). The rate of prevalence significantly differed with race, with Black people having the highest prevalence in all studied years. Only 7.1% (95% confidence interval [CI]: 0.049-0.102) and 2.67% (95% CI: 0.0137-0.0519) of this population underwent at least one ophthalmic outpatient examination or one vision examination per year. Older age, never married status, higher education, eye conditions, and diabetes were significantly associated with a higher probability of ophthalmic health care use. CONCLUSIONS: Adherence to follow-up among patients with self-reported glaucoma in this population-level study was lower than that in previously reported American, nonnationally representative studies. Barriers to adherence at the population level should be assessed to inform the design of future policy or program interventions.
