Impact of social determinants of health on follow-up adherence, testing completion, and outcomes among pediatric glaucoma patients at a tertiary care center

Purpose: To identify patient characteristics associated with visit attendance, treatment outcomes, and optical coherence tomography (OCT) testing in pediatric glaucoma patients at an urban tertiary care center. Methods: The records of patients with childhood glaucoma seen from 2015 to 2021 were reviewed. Primary outcomes were the proportion of scheduled visits completed, visual acuity and intraocular pressure (IOP) at most recent follow-up, and rates of OCT testing. Social determinants of health evaluated included race and ethnicity, distance of residence from clinic, insurance carrier type and residence within Baltimore City County, the latter two serving as proxies for socioeconomic status. Results: A total of 99 patients met inclusion criteria: 61% were male; 47%, White (non-Hispanic); 25%, Black (non-Hispanic); 11%, Hispanic/Latino; and 7% Asian/Pacific Islander. Mean distance from clinic was 45.3 miles. Mean visit completion rate was 90.4%; there was no statistically significant variation in visit completion rates by patient characteristics. IOP outcomes did not vary across patient groups, but visual acuity outcomes in affected eyes were significantly worse among Baltimore City County residents compared with non-residents. Only 22% of the cohort received ≥1 OCT per year, and patients living 0-29.9 miles from clinic had significantly lower odds of reaching the threshold than more distant patients. Patients with state-based insurance had significantly lower odds of being ≥50th percentile for rate of OCTs received compared to patients with commercial insurance. Conclusions: In children with glaucoma, residence within Baltimore City County was associated with significantly worse visual acuity outcomes, and close proximity to clinic was an independent predictor of lower rates of OCT testing, despite similar visit attendance rates and IOP outcomes across all groups.
