On-Call Examinations for Acute Onset of Flashes, Floaters, or Curtain by Junior Ophthalmology Residents: Outcomes, Safety, and Resource Use.

PURPOSE To determine whether an on-call system serviced by junior residents can safely triage patients with symptoms concerning for posterior vitreous detachment, retinal tear, and retinal detachment. DESIGN Quality improvement study structured as a prospective cohort study. PARTICIPANTS All symptomatic patients seen in 2017 by an on-call junior resident were followed up (257 patients). Those with follow-up within 6 months of initial presentation (228 patients, 246 unique encounters) were included. METHODS We prospectively tracked all symptomatic patients seen on-call by a junior resident in 2017 at a major academic medical center. MAIN OUTCOME MEASURES Incidence and predictors of true retinal tears or detachments, false-positive tears or detachments, false-negative tears or detachments, and resource use. RESULTS Of 246 symptomatic encounters, 83 (33.7%) had a perceived retinal tear or detachment. Residents used B-scan ultrasonography in a high number of encounters (41.0%). Ten (4.1%) false-positive tears or detachments were identified, with the presence of intraretinal hemmorhage predicting a false-positive examination (adjusted odds ratio, 3.86; 95% confidence interval, 1.1-13.5). Thirteen (5.3%) false-negative tears and no false-negative detachments were identified. Eleven (84.6%) false-negative tears underwent follow-up within days based on high-risk characteristics, and no false-negative tears progressed to detachment at follow-up. Measures of resource use included an in-person confirmation of examination findings by the senior resident or fellow in 59 encounters (24.0%) and shorter follow-up times to a retina rather than a nonretina clinic for 52 of 151 patients who showed no pathologic features on initial examination. CONCLUSIONS Junior residents can safely provide on-call triage of patients with symptoms concerning for a posterior vitreous detachment, retinal tear, or retinal detachment. The system requires moderate resource use, including occasional confirmatory examinations by a second physician and shorter follow-up times to retina clinic for high-risk patients.
