Assessing the Correlation Between a Surgeon's Ability to Draw a Procedure and Ability to Perform the Procedure

Abstract

The ability to assess a trainee's technical skill in a manner that maintains patient safety is critical to resident education. To do so, senior plastic surgery educators frequently ask residents to draw their proposed operation, presuming that a surgeon's ability to perform a surgery is reflected in his or her ability to diagram the procedure, independent of artistic ability. The purpose of this study was to delineate the relationship between the ability to draw a surgical procedure and execute it in a simulated model, and to determine if the ability to draw a procedure depends on artistic ability. Participants in varying levels of knowledge and surgical skill were asked to draw a 4-strand cruciate tendon repair and subsequently perform the procedure on a validated, simulated model. The participants were graded according to Objective Structured Assessment of Technical Skills scales by 2 blinded hand surgeon examiners. Statistical analysis was performed in SAS 9.4 with Spearman's rank correlation coefficient. The study was performed at Baylor Scott and White Health in Temple, TX in an office-based laboratory setting. Participants Forty participants comprised of senior medical students, plastic/orthopedic surgery residents, and plastic/hand surgery attendings. All 40 participants entered and completed the study. A statistically significant strongly positive correlation was found between overall assessment of drawing and overall assessment of performing the surgical procedure (p = 0.004). At the same time, the assessment of ability to draw the procedure was not associated with a general ability to draw or previous art training (p = 0.28). Our findings support the use of drawing a specific procedure as an assessment tool to evaluate a surgeon's ability to perform a procedure.
