Implementation of an Intraoperative Instructional Timeout Just Prior to Stapler Use Improves Proficiency of Surgical Stapler Usage by Surgery Residents

Abstract

Introduction: With the fragmented rotational structure of training, exposure to surgical staplers is not uniform across surgical residents. Traditionally, educational sessions dedicated to instruction in surgical staplers have taken place outside the operating room. This study implemented and evaluated an intraoperative timeout immediately prior to stapler use in cases with surgical residents.

Methods: During general surgery cases from June 1, 2017 until December 31, 2017, surgical teams, including the surgical attending, surgical resident, and scrub nurse participated in an intraoperative instructional timeout, during which proper use of linear or circular staplers was reviewed. At the conclusion of the timeout, residents were required to demonstrate proper stapler assembly and verbalize all technical steps involved in stapler use. Duration of each timeout was recorded. Immediately following the case, a pre-post survey was administered to each participating junior (R1-R2) or senior (R4-R5) surgical resident. The primary outcome was change in stapler use knowledge by surgical residents. Survey questions with Likert scale responses were analyzed using paired ttests, and responses from junior residents were compared to those from senior residents with independent t tests.

Results: Forty-three general surgery cases involved stapler use during the study period and implemented an intraoperative instructional timeout. The educational intervention increased stapler use knowledge significantly in all surgical residents. Prior to the timeout, junior residents reported significantly higher anxiety related to stapler usage compared to their senior counterparts; anxiety scores in junior residents decreased significantly for use of both linear and circular staplers. The mean timeout duration was 2.9 minutes (standard deviation 0.9 minutes, range 1.2-4.6 minutes). All participating surgical residents recommended routine implementation of an instructional timeout prior to intraoperative stapler use.

Conclusions: An intraoperative timeout dedicated to stapler teaching is effective in increasing proficiency and easing anxiety in all levels of surgical residents. Further research is warranted to determine whether this educational intervention would translate into fewer stapler use errors and decreased intraoperative complications.
