Effectiveness of facilitated introduction of a standard operating procedure into routine processes in the operating theatre: a controlled interrupted time series.

Morgan L, New S, Robertson E, et al. BMJ quality & safety. 2015;24:120-7.

Standard operating procedures, or SOPs, are a key tenet of human factors engineering. This time-series analysis found that implementing SOPs in the operating room did not change either surgical process outcomes, such as adherence to the WHO surgical checklist, or clinical outcomes. These results emphasize the challenge of applying systems solutions in clinical settings.
