Usability Assessment: The Foundation for Developing Surgical Video Review Systems

Surgical video review improves performance, but video capture, editing, sharing, and platform usability challenges hinder implementation. Evaluating platform usability by end-users is vital for effective adoption. In this study, we utilized a standardized measurement scale, the System Usability Scale (SUS), to measure the usability of an existing local network video capture (LNVC) platform within a surgical department. The existing LNVC system consists of intraoperative camera capture with an attached hard drive for data retention. The SUS survey was administered to surgical residents and faculty at a surgical department. The SUS was distributed via an online survey tool, and the SUS was calculated for distinct user groups. The median usability score for the entire cohort was low (Score:43, SUS average score: 68, 10thpercentile score:40). The median score was worst among routine video users (Score: 36). For the first time, we demonstrate that LNVC has among the lowest usability scores in a single surgery department.
