Ambulatory surgery centers (ASCs) are increasingly being used to provide surgical care. The AHRQ Surveys on Patient Safety Culture™ (SOPS®) Ambulatory Surgery Center Survey seeks opinions from the field regarding safety culture in the ambulatory surgical center environment. The survey is presented with additional resources to help organizations assess their safety culture, including the results of a pilot program testing the survey and a user's guide. Voluntary data submission will be open June 1-22 for ASCs that have administered the survey.
