Right Case, Right Time: Which Procedures Best Differentiate General Surgery Trainees' Operative Performance?

OBJECTIVE

Assessing surgical trainee operative performance is time- and resource-intensive. To maximize the utility of each assessment, it is important to understand which assessment activities provide the most information about a trainee's performance. The objective of this study is to identify the procedures that best differentiate performance for each general surgery postgraduate year (PGY)-level, leading to recommendations for targeted assessment.

DESIGN

The Society for Improving Medical Professional Learning (SIMPL) operative performance ratings were modeled using a multilevel Rasch model which identified the highest and lowest performing trainees for each PGY-level. For each procedure within each PGY-level, a procedural performance discrimination index was calculated by subtracting the proportion of "practice-ready" ratings of the lowest performing trainees from the proportion of "practice-ready" ratings of the highest performing trainees. Four-quadrant plots were created using the median procedure volume and median discrimination index for each PGY-level. All procedures within the upper right quadrant were considered "highly differentiating, high volume" procedures.

SETTING

This study was conducted across 70 general surgical residency programs who are members of the SIMPL collaborative.

PARTICIPANTS

A total of 54,790 operative performance evaluations of categorical general surgery trainees were collected between 2015 and 2021. Trainees who had at least 1 procedure in common were included. Procedures with less than 25 evaluations per training year were excluded.

RESULTS

The total number of evaluations per procedure ranged from 25 to 2,131. Discrimination values were generated for 51 (PGY1), 54 (PGY2), 92 (PGY3), 105 (PGY4), and 103 (PGY5) procedures. Using the above criteria, a total of 12 (PGY1), 15 (PGY2), 22 (PGY3), 21 (PGY4), and 28 (PGY5) procedures were identified as highly differentiating, high volume procedures.

CONCLUSIONS

Our study draws on national data to identify procedures which are most useful in differentiating trainee operative performance at each PGY-level. This list of procedures can be used to guide targeted assessment and improve assessment efficiency.

The Feasibility of Real-Time Intraoperative Performance Assessment With SIMPL (System for Improving and Measuring Procedural Learning): Early Experience From a Multi-institutional Trial

PURPOSE

Intraoperative performance assessment of residents is of growing interest to trainees, faculty, and accreditors. Current approaches to collect such assessments are limited by low participation rates and long delays between procedure and evaluation. We deployed an innovative, smartphone-based tool, SIMPL (System for Improving and Measuring Procedural Learning), to make real-time intraoperative performance assessment feasible for every case in which surgical trainees participate, and hypothesized that SIMPL could be feasibly integrated into surgical training programs.

METHODS

Between September 1, 2015 and February 29, 2016, 15 U.S. general surgery residency programs were enrolled in an institutional review board-approved trial. SIMPL was made available after 70% of faculty and residents completed a 1-hour training session. Descriptive and univariate statistics analyzed multiple dimensions of feasibility, including training rates, volume of assessments, response rates/times, and dictation rates. The 20 most active residents and attendings were evaluated in greater detail.

RESULTS

A total of 90% of eligible users (1267/1412) completed training. Further, 13/15 programs began using SIMPL. Totally, 6024 assessments were completed by 254 categorical general surgery residents (n = 3555 assessments) and 259 attendings (n = 2469 assessments), and 3762 unique operations were assessed. There was significant heterogeneity in participation within and between programs. Mean percentage (range) of users who completed ≥1, 5, and 20 assessments were 62% (21%-96%), 34% (5%-75%), and 10% (0%-32%) across all programs, and 96%, 75%, and 32% in the most active program. Overall, response rate was 70%, dictation rate was 24%, and mean response time was 12 hours. Assessments increased from 357 (September 2015) to 1146 (February 2016). The 20 most active residents each received mean 46 assessments by 10 attendings for 20 different procedures.

CONCLUSIONS

SIMPL can be feasibly integrated into surgical training programs to enhance the frequency and timeliness of intraoperative performance assessment. We believe SIMPL could help facilitate a national competency-based surgical training system, although local and systemic challenges still need to be addressed.
