In order to assist hospitals with measuring safety culture, the Agency for Healthcare Research and Quality (AHRQ) published baseline safety culture measurements from nearly 400 hospitals in 2007. These results were obtained from administering the AHRQ Hospital Survey on Patient Safety Culture, which measures 12 components of safety culture ranging from perceived teamwork to management support of safety activities. The 2008 update is intended to serve as a "rolling benchmark" that hospitals may use for comparative purposes and provides analysis of safety culture results for different regions, hospital types, hospital size, respondent work areas, and staff positions.
