OBJECTIVES: Workflow efficiency in ophthalmology operating rooms is critical because the global demand for retina surgeries is expected to outpace the supply of workforce. A bench time trial was conducted to compare the system mean duration of console set-up and tear-down time with the new UNITY® Vitreoretinal Cataract System (UNITY VCS) and the current standard of care device, CONSTELLATION® Vision System (CONSTELLATION).
METHODS: A time trial included 9 ophthalmic technicians/nurses with an average of 17.9 years of experience in vitreoretinal surgery. Each participant performed system setup and tear-down workflows of UNITY VCS and CONSTELLATION for vitreoretinal surgery. Participants were timed by observers with a stopwatch after 30 minutes of shared hands-on time with UNITY VCS. Statistical analyses were conducted to test the difference of matched pairs. Four participants further responded to the validated ten-item System Usability Scale (SUS).
RESULTS: System set-up time was 21.6% (59.30 seconds) faster with UNITY VCS (215.64 seconds) compared to CONSTELLATION (274.94 seconds) (P<0.001). System teardown time was 42.1% faster (22.79 seconds) with UNITY VCS System (31.33 seconds) compared to CONSTELLATION (54.12 seconds) (P<0.001). UNITY VCS releases ~1.5 minutes of operating room turnover time per surgical case. The mean (SD) SUS score was 89.38 (7.47) which corresponds to the 97th percentile.
CONCLUSIONS: This study showed that the new UNITY® Vitreoretinal Cataract System may deliver superior efficiency compared with the CONSTELLATION® Vision System and better system usability in system set-up and tear-down workflows.
