Crew resource management (CRM), a type of team training, is a prime example of an aviation strategy often applied to patient safety. Despite many calls to disseminate CRM throughout health care, data on its effectiveness in improving safety is lacking. This multi-site study examined safety culture, as measured by the AHRQ Hospital Survey on Patient Safety Culture, before and after implementation of CRM in eight departments, across three hospitals. After the training, investigators found a significant, consistent improvement across multiple domains of safety culture, particularly in the areas of teamwork and communication. They propose more widespread implementation of CRM as a strategy to enhance safety culture. A past PSNet interview described the application of CRM to health care.
