The World Health Organisation's Surgical Safety Checklist has been adopted and implemented by many hospitals throughout the world: from large tertiary teaching hospitals in wealthy countries, to small hospitals in low-resource settings.
The benefits to each hospital however are likely not the same. Does the WHO SSC implemented in a hospital that already has a 'Time Out' process bring the same benefit, if any, as to a hospital for which the checklist was completely new? Possibly not.
Several studies across a wide range of health systems have shown conflicting results in terms of reducing morbidity, mortality and length of stay.

Sometimes even correlations are too significant and important to just be fobbed off by epidemiological cliché. This collection contains articles repeatedly showing association between doctor characteristics, particularly gender, and patient outcome.
Although most recently shown by Wallis in JAMA Surgery (2021), gender-outcome associations are depressingly not new.
- Female patients treated by male surgeons more commonly experience post-operative complications and death than when treated by female surgeons. (Wallis 2021)
- Care from male surgeons and/or anaesthesiologists is associated with longer lengths of stay after cardiac surgery. (Sun 2021)
- Female heart-attack patients are less likely to survive when treated by a male physician than a female physician. (Greenwood 2018)
- Treatment from female surgeons is associated with a lower 30 day mortality than the same from male surgeons. (Wallis 2017)
- In-patient care from a female physician is associated with lower 30 day mortality and readmission rate among elderly patients. (Tsugawa 2017)
The cause of this gender outcome disparity is unclear, and importantly these studies are hypothesis forming, rather than proving. Nonetheless both Wallis (2021) and Greenwood (2018) hint at causes, namely a lack of experience treating female patients for some male doctors, and consequential lesser understanding of gender-disease differences.
The temptation when attempting to understand this is to descend into medical gender essentialism – ironically, probably a contributor to the actual outcome disparities.
A similar doctor-outcome disparity is seen with age. Among physicians, care from older doctors was associated with worse outcomes (Tsugawa 2017), yet for surgeons older age conferred better outcomes (Tsugawa 2018; Satkunasivam 2020). Causes here are possibly a nexus between experience, up-to-date knowledge and work volume – but also, still unclear.
