Ophthalmic Emergency Department Visits: Factors Associated With Loss to Follow-up

Abstract

To describe follow-up rates for patients referred for outpatient ophthalmic care after emergency department (ED) discharge and identify patient and visit characteristics associated with loss to follow-up (LTFU). Single-institution retrospective cohort study. We analyzed the medical records of 2,206 patients seen in the ED for an eye-related issue who were subsequently scheduled for ophthalmology follow-up between 2013 and 2019 at a single tertiary health system. The main outcome measures were the frequency of and risk factors for LTFU and ED revisits. In total, 1,649 (74.8%) patients completed follow-up within 2months of an index ED visit. In multivariable analysis, younger age (P < .001), a nonurgent ophthalmic condition or nonophthalmic primary diagnosis (P < .001), scheduled follow-up >5days after the ED visit (P < .001), additional follow-up appointments (<.001), no prior history of ophthalmology appointments (P= .045), a visual acuity of 20/40 or better (P= .027), and having Medicaid or being uninsured (P < .001) were significantly associated with LTFU. The presence of an interpreter significantly increased the likelihood of follow-up among non-English speaking patients (P < .001). LTFU was significantly associated with an ED revisit within 4months of an index visit, and the ED revisit rate was significantly higher for patients LTFU vs those who completed follow-up (5.7% vs 1.1%; P < .001). A quarter of patients referred for ophthalmic care after an ED presentation were LTFU. We identified numerous factors associated with LTFU that could be used to develop interventions to enhance follow-up. In addition, patients who were LTFU were more likely to revisit the ED for the same ophthalmic condition.
