Simulation-based training for intraoperative posterior capsule rupture management: an analysis of nontechnical skills development and the relationship between technical and nontechnical skills

To analyse development of individual nontechnical skills (NTS) domains after undertaking a previously developed simulation-based training model and analyse the relationship between technical skills (TS) and NTS in ophthalmic surgery.

The simulation-based training model involved a cataract surgery case complicated by intraoperative posterior capsule rupture. Cataract surgeons underwent the simulation twice, separated by a training intervention. Two blinded independent experts assessed participants’ NTS using HUFOES, NOn-Technical Skills for Surgeons (NOTSS), and the OSATS global rating scale for TS. Paired t-tests assessed differences in individual NTS domains, with p < 0.05 indicating significance. The Pearson Product Moment Correlation Coefficient was used to assess the correlation between scores from each scoring system.

All NTS domains within HUFOES and NOTSS demonstrated statistically significant improvements secondary to the training intervention. Positive correlations were demonstrated between HUFOES and OSATS scores in the pre- and post-training simulations, r = 0.870 (p < 0.001) and r = 0.861 (p < 0.001), respectively. Positive correlations were also demonstrated between NOTSS and OSATS scores in pre- and post-training simulations, r = 0.849 (p < 0.001) and r = 0.757 (p = 0.001), respectively. Positive correlations were demonstrated between HUFOES and NOTSS scores; r = 0.979 (p < 0.001) (n = 17) and r = 0.959 (p < 0.001) for pre- and post-training simulations, respectively.

All NTS domains contained within HUFOES and NOTSS demonstrated significant increases following the completion of the simulation-based training model. Positive correlations exist between an ophthalmic surgeon’s TS and NTS. This is the first study to report these findings within ophthalmic surgery.
