Outpatient and Ambulatory Surgery CAHPS (OAS CAHPS)
Overview: The Consumer Assessment of Healthcare Providers and Systems Outpatient and Ambulatory Surgery Survey (OAS CAHPS) collects information about patients’ experiences of care in hospital outpatient departments (HOPDs) and ambulatory surgery centers (ASCs). As of December 2012 there were approximately 5,357 Medicare-certified ASCs and about 3,360 HOPDs. In 2006, there were almost 35 million ambulatory surgical visits; approximately 20 million surgeries and procedures were performed in HOPDs, and approximately 15 million were performed in ASCs. Medicare payments to ASCs have increased by 24% over the years, from $2.9 billion in 2007 to $3.6 billion in 2012. Considering the growing number of ASCs and the increase in Medicare expenditures for outpatient surgical services in both ASCs and HOPDs, the implementation of OAS CAHPS will provide statistically valid data from the patient perspective to inform quality improvement and comparative consumer information about outpatient facilities.
About the survey: Patients 18 years old and older who had both medically and non-medically necessary surgeries and/or procedures are eligible. The survey includes questions about patients’ experiences with their preparation for the surgery or procedure, check-in processes, cleanliness of the facility, communications with the facility staff, discharge from the facility, and preparation for recovering at home. The survey also includes questions about whether patients received information about what to do if they had possible side-effects during their recovery. OAS CAHPS is designed to be national in scope and will require standardized administration protocols. There are three approved modes of administration: mail only, telephone only, and mail with a telephone follow-up.
Plans for a mode experiment to test a Web mode of administration: CMS is interested in investigating the feasibility of offering the survey using a Web-based format (see 82 FR 59216). As part of the investigation, CMS has designed a new mode experiment to assess the impact of adding Web-based survey administration. This mode experiment will test five administration modes with patients who receive outpatient surgical care: mail only, telephone only, web only, web with mail follow-up and web with a telephone follow-up. The mode experiment is planned for the Spring of 2019.
Public reporting and policy relevance: OAS CAHPS initiated voluntary national implementation in January 2016. The first publicly reported data were posted in 2018.
