Vail D, et al. - In this retrospective claims-based cohort analysis, researchers intended to determine if there is a connection between modality of rhegmatogenous retinal detachment (RRD) repair and day of the week that patients receive a diagnosis or undergo RRD repair. The sample consisted of primary RRD surgery for 38,144 commercially insured patients in the US who received a diagnosis of incident RRD between January 1, 2008, and December 31, 2016, and underwent repair within 14 days of diagnosis. RRDs repaired during the weekend were more probable to be repaired with pneumatic retinopexy, patients undergoing pneumatic retinopexy on Sundays were more prone to undergo reoperation, and patients who received a diagnosis on Fridays waited longer for repair. Such outcomes indicate variation in care patterns of rhegmatogenous retinal detachment by day of the week.
