Abstract

Abstract : Objective: The study goals were to examine wrong intraocular lens (IOL) implant adverse events in the Veterans Health Administration (VHA), identify root causes and contributing factors, and describe system changes that have been implemented to address this challenge. Design: This study represents collaboration between the VHA's National Center for Patient Safety (NCPS) and the National Surgery Office (NSO). Participants: This report includes 45 wrong IOL implant surgery adverse events reported to established VHA NCPS and NSO databases between July 1, 2006, and June 31, 2014. There are approximately 50, 000 eye implant procedures performed each year in the VHA. Methods: Wrong IOL implant surgery adverse events are reported by VHA facilities to the NCPS and the NSO. Two authors (A.C. and J.N.) coded the reports for event type (wrong lens or expired lens) and identified the primary contributing factor (coefficient κ = 0.837). A descriptive analysis was conducted, which included the reported yearly event rate. Main Outcome Measure: The main outcome measure was the reported wrong IOL implant surgery adverse events. Results: There were 45 reported wrong IOL implant surgery adverse events. Between 2011 and June 30, 2014, there was a significant downward trend ( P = 0.02, R 2 = 99.7%) at a pace of −0.08 (per 10, 000 cases) every year. The most frequently coded primary contributing factor was incomplete preprocedure time-out (n = 12) followed by failure to perform double check of preprocedural calculations based upon original data and implant read-back at the time the surgical eye implant was performed (n = 10). Conclusions: Preventing wrong IOL implant adverse events requires diligence beyond performance of the preprocedural time-out. In 2013, the VHA has modified policy to ensure double check of preprocedural calculations and implant read-back with positive impact. Continued analysis of contributing human factors and improved surgical team communication are warranted.
