  • [Title] Observational teamwork assessment for surgery: content validation and tool refinement.
  • BACKGROUND: Effective teamwork is crucial for safe surgery.
  • Failures in nontechnical and teamwork skills are frequently implicated in adverse events.
  • The Observational Teamwork Assessment for Surgery (OTAS) tool assesses teamwork of the entire team in the operating room.
  • Empirical testing of OTAS has yet to explore the content validity of the tool.
  • STUDY DESIGN: This was a cross-sectional observational study.
  • Data were collected in 30 procedures by 2 trained researchers.
  • Five teamwork behaviors were scored (ie, communication, leadership, cooperation, coordination, and monitoring) and behavior exemplar completion was recorded (phase 1).
  • Expert operating room personnel (5 surgeons, 5 anesthesiologists, and 5 scrub nurses) assessed the content validity of the OTAS exemplar behaviors.
  • Finally, a panel of operating room patient-safety experts refined the exemplars (phase 2).
  • RESULTS: In total, the observability (presence/absence) of 130 exemplars was assessed by 2 blinded observers in 30 general surgical cases.
  • Observer agreement was high (Cohen's κ ≥ 0.41) for 83.85% (109 of 130) of exemplar behaviors; 60.77% (79 of 130) of exemplar behaviors were observed frequently with high observer agreement.
  • The majority of the exemplars were rated by expert operating room practitioners and an expert panel as substantial contributors to teamwork and patient safety.
  • Based on expert consensus, 21 behavior exemplars were removed from OTAS and an additional 23 were modified.
  • CONCLUSIONS: The exemplars of OTAS demonstrated very good content validity.
  • Taken together with recent evidence on the construct validity of the tool, these findings demonstrate that OTAS is psychometrically robust for capturing teamwork in the operating room.
