How to WHO: lessons from aviation in checklists and debriefs

The World Health Organization (WHO) surgical safety checklist (SSC) has had an overall positive impact; however, it has not completely prevented adverse events and compliance with the checklist varies. The aviation industry is considered to have better engagement with their safety checklists, reporting not only safety improvements, but also a cultural shift in their checklist philosophy over recent years.

We explored the personal attitudes of pilots working in the aviation industry to identify principles of an effective checklist philosophy that could be transposed to the healthcare setting to empower more effective, consistent and ultimately successful implementation of the WHO SSC. A questionnaire was developed by the authors. Three airline pilots were interviewed via telephone, and asked questions regarding the logistics of and attitudes to checklists in the aviation industry.

Several key factors for successful checklist implementation were identified. These include regular training and education on human factors and the checklist's purpose, and institution of an atmosphere that is receptive, engaged and welcoming. Much can be learned from the aviation industry, where not only has the incidence of adverse events decreased, but the attitudes of people working in the industry have also transformed.

The WHO SSC is an invaluable tool used in healthcare settings worldwide. However, it is not a standalone commodity. To be effective, it necessitates steadfast engagement from the team members involved in its implementation. Human and checklist must work in partnership, using each other's strengths and fallibilities, to optimise outcomes and prevent risks to patient safety.
