176 I Chapter 6 RESULTS The study coordinator observed that one out of four staff surgeons carried out an official introduction round, during which all team members present, publicly said their full names including role. The SUPRASS item ‘confirm all team members have introduced themselves by name and role’ was in all 34 cases checked off as completed. All names and roles were noted on the whiteboard in the OT before start of procedure, usually by the circulating nurse although surgeons also did write down their name with their phone number themselves. In total, 238 postoperative questionnaires were completed directly after the 34 recorded surgical procedures. According to the specific OT team member filling out the questionnaire, in 82.4% (n=196) of the cases it was stated that the entire OT team was indeed introduced. In total, 41% (n=40, out of 98) of the OT team members were able to recall all the names of their teammembers attending the postoperative MDR team debriefing. As shown in Table 1, the name of the primary surgeon was remembered most often (93%, n=68) and the name of the medical intern least often (32%, n=18). The primary surgeon could remember the name of the anaesthesiologist only on 50% of occasions (n=14) and the scrub nurse’s name in 58% of times (n=12). The anaesthesiologist could remember the name of the primary surgeon in 75% of the time (n=9) and the scrub nurse’s name in 38% of the time (n=8). As shown in Table 2, there was no significant difference between the times the OT team was introduced prior to the start of the surgical procedure, according to the questionnaire, versus times thenames of the specificOT teammemberswere remembered at the postoperative MDR team debriefing. There was no significant correlation between name and role introduction actually being performed and the percentage of correct name recall (P-value<0.310, 96%CI –0.83 to 4.06). About one year after implementation (September 2019), the theatre cap challenge was evaluated by asking a medical student, unfamiliar to OT staff, to count (on two randomly chosen mornings at the start of the working day and one time during lunchtime break, for 1.5h) how many individuals, and who were actually wearing the name
