Gathering Validity Evidence to Adapt the Non-technical Skills for Surgeons (NOTSS) Assessment Tool to the United States Context

Abstract

Nontechnical skills are of increasing focus for safe and effective performance in the operating room. Assessment tools have been developed in Europe, Africa, and Asia but not adapted to the unique aspects of surgical delivery in the United States. Our objective was to use the Non-Technical Skills for Surgeons (NOTSS) assessment tool as a basis to establish consensus on essential nontechnical skills for surgical trainees and practicing surgeons in the U.S surgical context. A mixed-methods research design was used in the form of a modified Delphi process to build consensus on essential NOTSS. A panel of surgical experts from hospitals across the U.S used this iterative process in 4 rounds to generate, rate, and classify behaviors. The primary outcome was consensus on behaviors as being essential for surgeons to achieve the best patient outcomes in the operating room, with a median rating of ≥6 on a 7-point scale for inclusion. A total of 10 surgical experts participated. One hundred and thirty eight behaviors were generated in Round 1, and reduced to 100 behaviors in Rounds 2 and 3 based on application of inclusion criteria. The final skill list consisted of behaviors in Situation Awareness (n = 26), Decision Making (n = 18), Teamwork (n = 25), and Leadership (n = 31). No additional NOTSS categories or elements emerged from the analysis. In Round 4, all 100 behaviors were successfully grouped into 12 nontechnical skills elements. Labels and definitions were reworded to reflect the U.S. context, and an appropriate assessment scale was selected. A panel of surgical experts from across the U.S. reached consensus on the essential NOTSS to achieve the best patient outcomes in the operating room. These behaviors form an empirical basis for the first context-specific nontechnical skills assessment and training tool for practicing surgeons in the U.S.
