Operative time and complication rates of resident phacoemulsification surgeries in a national university hospital: A five-year review

Abstract

Purpose: To determine the operative time and complication rates of resident phacoemulsification surgeries at different time points in training. Methods: Retrospective cross-sectional study at the Department of Ophthalmology of the Philippine General Hospital. All resident-performed elective adult phacoemulsification surgeries from January 1, 2014, to December 31, 2018, were included, while operations with planned anterior or posterior procedures were excluded. Cases were arranged chronologically and divided into time points with 25 cases each. Operative time and complication rates were computed for each time point. As defined by the ICO Ophthalmology Surgical Competency Assessment Rubric (OSCAR), 30 minutes was used to gauge competency based on operative time, while complications were compared to published rates for residents. Results for the first 50 cases, the minimum number required by graduation, were also compared with succeeding cases. Results: A total of 4635 cases were included. Residents performed an average of 115.9 ± 30.4 cases, with no significant difference among residents (F(4,35)=2.64, p=0.12). Overall complication rate was 6% (n=276), similar to those reported internationally. Both median operative time and complication rates decreased significantly for every time point in training (p<0.001). After 50 cases, only 40% (n=16) of residents reached the operative time of 30 minutes. Median operative time is significantly lower when comparing the first 50 surgeries with the succeeding cases (37 minutes vs 29 minutes, p<0.001). Likewise, complication rate is also significantly lower (9.3% vs 3.5%, Χ2 (1, N=4635) = 68.481, p<0.001), with an odds ratio of 2.85 (p<0.001, 95% CI [2.2, 3.7]). Conclusion: There are significant improvements in both operative time and complication rates as more surgeries are performed. However, the minimum required 50 cases is not enough for resident competency based on operative time and complication rates.
