America’s Best Ambulatory Surgery Centers 2025

For the ranking of America’s Best Ambulatory Surgery Centers, the following was taken into consideration:

(1) From June to August 2024, Statista conducted a nationwide online survey among medical professionals (medical doctors/surgeons, registered nurses, nursing assistants, therapists) and staff working in the management/administration in ambulatory surgery centers. The survey was available to medical experts to participate on Newsweek.com. Additionally, participants were invited via e-mail. Participants were asked to recommend notable ambulatory surgery centers in their respective state. Recommendations for own employer/ambulatory surgery center were not allowed. For each recommended ambulatory surgery center participants were asked to rate three quality dimensions on a scale from 1 (“Poor”) to 10 (“Excellent”): Quality of surgical care, Quality of follow-up care, Management of waiting time. A quality score was assigned to each facility based on the weighted average of the other three dimensions. Additionally, the professional experience of the participant was considered, and participants could name standout specialties: Orthopedics, ophthalmology and/or gastroenterology.

(2) CMS Measures: The U.S. Centers for Medicare & Medicaid Services provides data on ASCs in the Ambulatory Surgical Center Quality Reporting. 9 Measures were included into the analysis of this year’s edition of the ranking.

(3) Publicly available data from the Outpatient and Ambulatory Surgery Consumer Assessment of Healthcare Providers and Systems (OAS CAHPS) survey was used to analyze patient experience. Survey topics associated to patient care and satisfaction were included.

(4) Furthermore, accreditation data based on the Accreditation Association for Ambulatory Health Care (AAAHC) was include in this year’s edition of the ranking, containing the following accreditation / certification programs: Ambulatory Accreditation, Medicare Deemed Status Accreditation, Advanced Orthopaedic Certification.

The evaluation of ambulatory surgery centers was based on a scoring model including four pillars: the reputation score (45%), the CMS Measures score (45%), the patient experience score (7.5%) and the accreditation score (2.5%). The reputation score was calculated based on recommendations from medical professionals (80%) and the quality dimensions score (20%).
