The influence of working in a Black Box monitored operating room on safety behaviour I 191 7 RESULTS On March 26th 2019 the survey was sent to 24 surgical staff members, 4 surgical fellows, 23 surgical residents, 71 staff anaesthesiologist, 74 anaesthesiology residents, 86 anaesthesiology technicians, 139 operating theatre nurses, 14 urology professionals, 9 paediatric surgeons, 9 cardiothoracic surgeons, 19 orthopaedic surgeons, 6 plastic surgeons, 13 neurosurgeons, 28 gynaecologists, and 2 Ear, Nose and Throat (ENT) staff members. In total, 521 healthcare professionals working in the OR (across all different surgical specialties) received the survey. Before sending out the general reminder, 82 professionals completed the survey (initial response rate of 14.56%). A general reminder was sent on April 25th 2019. The survey was closed on May 29th 2019. In total, 126 professionals completed the entire survey. This resulted in a final response rate of 24.18%. Most responses were received from the operating nurses (23.02% of total) and staff surgeons (24.6% of total). The complete details and baseline characteristics of the respondents are presented in Table 1. Patient Safety Dimensions The overall means of the 11 validated patient safety dimension and PRR’s are presented in Table 2. The operating nurses rated the overall perception of safety the lowest (mean 2.89 (SD 0.45)) while the anaesthesiology residents rated it to be the highest (mean 3.39 (SD 0.32)). Teamwork within the department was rated the most positive with an overall mean of 3.69 (SD 0.64), PRR 73.02%), followed by communication openness (mean 3.60 (SD 0.76), PRR 63.49%). Overall, changing shifts was rated the lowest (mean 2.90 (SD 0.48), PRR 21.43%). As presented in Table 2, there were significant differences concerning several safety dimensions between the different roles in the OR (Teamwork within department (P 0.001), Non-punitive response to error (P 0.016), Communication openness (P 0.001), Feedback and learning from errors (P 0.045), Supervisor expectations and actions promoting safety (P < 0.0001), Adequate staffing (P < 0.003). The overall means of the 11 validated dimensions per department are presented in Figure 1.
