96 I Chapter 3 The multivariable linear regression, correcting for all potential confounders (simple linear regression table in the Online Appendix), showed that the primary surgeon was significantly more satisfied concerning all 3 satisfaction factors, compared to the other team members. Number of previously attended Black Box team debriefings was significantly associated with a higher satisfaction score for all 3 satisfaction factors (Beta coefficient = 0.29, 95%CI 0.09–0.49, Beta coefficient = 0.414, 95%CI 0.25–0.57, Beta coefficient = 0.422, 95%CI 0.59–0.26). Number of team members attending the team debriefing and number of work days between the procedure and debriefing were not significantly associated with the satisfaction scores. Total number of events reported in the performance report feedback was negatively associated with satisfaction factor 1 (Beta coefficient = − 0.013, 95%CI − 0.02 to − 0.002). Results of the multivariable linear regression analyses are presented in Table 3. Figure 3. T otal mean scores of the questions (Q0, Q1, Q2, Q5, Q6, Q7, Q13, Q14a, Q14b, Q15, Q16, Q17) included in factor 1 representing the team member’s attitude towards the value of team debriefing with the OR Black Box®, per role in the operating theatre.
