Non-technical skills simulation-based training model for managing intraoperative posterior capsule rupture during cataract surgery.

Abstract

To develop and implement a simulation-based training model for the management of posterior capsule rupture (PCR) from a non-technical skills (NTS) perspective, and analyse changes in participant's NTS and technical skills (TS). The simulation-based training model consisted of two identical PCR simulations with NTS stressors applied, separated by a predominantly NTS focussed training intervention. Participants' TS and NTS were evaluated by two blinded assessors using the Objective Structured Assessment of Technical Skill (OSATS) global rating scale and the HUman Factors in intraoperative Ophthalmic Emergencies Scoring System (HUFOES) respectively. Paired t-tests were used to establish the difference in mean HUFOES and OSATS scores between initial and repeat simulations; p < 0.05 indicated statistical significance. McGaghie's model of translational outcomes for simulation-based learning was used to establish the simulation model's educational status. Seventeen cataract surgeons of varying training grades participated in the simulation-based training model. NTS improved with statistical significance; mean HUFOES scores increased from 48.7 ± 16.6 to 59.2 ± 14.8 (p < 0.001). Mean OSATS scores increased without statistical significance from 16.0 ± 7.3 to 17.9 ± 8.3 (p = 0.07). This simulation model achieved Level 1 (internal acceptability) and Level 2 (contained effects) according to McGaghie's model. This novel simulation-based training model was designed to improve the NTS required for managing intraoperative PCR, through the provision of an interactive training session. Statistically significant improvements in participants' NTS in combination with statistically insignificant improvements in TS demonstrate that the simulation-based training model has specificity within the NTS domain.
