Compliance with the surgical safety checklist in Switzerland: an observational multicenter study based on self-reported data

Abstract

Abstract Background Since publication of the surgical safety checklist by the WHO in 2009, it has been introduced in many hospitals. However, frequency and quality of surgical safety checklist use is often low probably limiting the effectiveness of the checklist in preventing patient harm. The focus of this study was to examine the current state of compliance with the surgical safety checklist in Switzerland and to evaluate how the data relates to international comparative data. Methods Between November 2020 and March 2021 twelve hospitals with 15 sites collected for at least 200 surgical interventions each whether the three sections of the surgical safety checklist (Sign In, Team Time Out, Sign Out) have been applied. This data collection was part of a large quality improvement project focusing on measuring and improving compliance with the surgical safety checklist via peer observation and feedback. Descriptive statistics were used to analyze the data; chi-square tests were used to compare sub-samples. Results The hospitals collected valid compliance data for 8622 surgical interventions. Mean compliance rate was 91% when distinguishing between the two categories applied (including partially applied) and not applied. In line with previous research, Sign In (93%) and Team Time Out (94%) sections have been applied more frequently than Sign Out (86%). All three surgical safety checklist sections have been applied in 79% of the surgical interventions, no sections in 1%. Conclusions The results of this study indicate that the overall application of the surgical safety checklist in Switzerland can be considered high, although the completeness, especially of the Sign Out section, could be improved. At present, it seems difficult to compare compliance rates from different studies as measurement methods and definitions of compliance vary widely. A systematization and homogenization of the methodology within, but also beyond, national borders is desirable for the future.
