This AHRQ-supported study discusses one of the best-studied tools to measure and assess patient safety culture. Investigators present the cumulative findings from administering the Safety Attitude Questionnaire (SAQ) to more than 10,000 providers in 203 clinical areas and in 3 countries. The domains that encompass provider attitudes include teamwork climate, safety climate, perceptions of management, job satisfaction, working conditions, and stress recognition. The authors describe their findings with a goal that their tool will allow health care organizations to measure safety attitudes and compare themselves across domains to others. A past study described the results of using such a tool in an academic medical center.
