Reality check of using the surgical safety checklist: A qualitative study to observe application errors during snapshot audits

BACKGROUND: The WHO Surgical Safety Checklist (SSC) was established to address important safety issues and to reduce the number of surgical deaths. So far, numerous reports have demonstrated sub-optimal implementation of the SSC in practice and limited improvements in patient outcomes. Therefore, the aim of this study was to audit the SSC-practice in a real-world setting in a university hospital setting. METHODS: From 2015 to 2016, independent observers performed snapshot audits in operating theatres and shadowed the three phases of the SSC. Using a 4-point Likert-scale to rate the compliance on each audit day, we generated a report highlighting possible improvements and provided feedback to the operating team members. RESULTS: Audits were performed on 36 operating days (2015: n = 19; 2016: n = 17), in which a total of 136 surgical interventions were observed. Overall, the percentage of “very good compliance” improved from 2015 to 2016: for the sign-in from 52.9% to 81.2% (p = 0.141), for the team-time-out from 33.3% to 58.8% (p = 0.181), and for the sign-out from 21.4% to 41.7% (p = 0.401). The qualitative review revealed inconsistencies when applying the SSC, of which the missing documentation of an actually performed item or the wrong timing for an item was most common. CONCLUSION: Snapshot audits revealed that SSC compliance has improved over the observed period, while its application revealed inconsistencies during the three phases of the SSC. Snapshot audits proved to be a valuable tool in the qualitative analysis of SSC compliance and gave more insight than a mere completeness check of ticks in SSC documents.
