America's Best

Ambulatory Surgery Centers 2022

Ambulatory surgical centers have become a big part of American medicine. These are facilities where patients can have specific surgical procedures that usually don't require them to be hospitalized, meaning you can have the operation and then be back home quickly, often the same day. Currently there are over 5,000 medicare certified ambulatory surgical centers around the country in all the major surgical specialties – orthopedic surgery, cardiac surgery, eye surgery, spinal surgery and so on.

To help our readers make knowledgeable choices when they seek care for themselves or loved ones, Newsweek has again partnered with respected global research firm Statista to name America's Best Ambulatory Surgery Centers. This year our list spotlights 470 facilities in the 25 states with the most ambulatory surgery centers. The states are Arizona, California, Colorado, Florida, Georgia, Illinois, Indiana, Kansas, Louisiana, Maryland, Michigan, Minnesota, Mississippi, Missouri, New Jersey, New York, North Carolina, Ohio, Oregon, Pennsylvania, South Carolina, Tennessee, Texas, Washington and Wisconsin.

We hope these trustworthy, carefully vetted rankings of America's Best Ambulatory Surgery Centers help you make choices with confidence.

Methodology

Working with data research firm Statista, we analyzed ambulatory surgical center performance data. As part of the research, we conducted a survey of experts, asking nurses, therapists, physicians and surgeons, and administrators in ASCs for the best surgery centers in their state or a state they're familiar with. We also invited them to assess how well the ASC in question has handled the challenges of the COVID-19 crisis.

The rankings included Ambulatory Surgery Centers operating exclusively for the purpose of providing surgical services to patients not requiring hospitalization and in which the expected duration of services would not exceed 24 hours following an admission. An unanticipated medical circumstance may arise that would require an ASC patient to stay in the ASC longer than 24 hours, but such situations should be rare.

The research project analyzed more than 4,600 Ambulatory Surgery Centers in 25 states. The 470 Best Ambulatory Surgery Centers were identified, with a varying number of ASCs awarded per state: California, with 83, had the most, while Mississippi is represented with 4 ambulatory surgery centers.

The Ranking is based on the Overall Score of each facility, which is based on the Reputation Score and the KPI Data Score. The Reputation Score is based on three sub-scores: for recommendations, for quality and for the handling of the situation regarding Covid-19 (as of September 2021).

Additionally, experts from all over the US were able to participate in the survey of the Best Ambulatory Surgery Centers in the US on newsweek.com. All data was collected by Newsweek and Statista during the survey period from July to September 2021. Self-recommendation was not possible (e.g. a recommendation of the ambulatory surgery centers someone worked for was not counted in the evaluation).

Participants were asked to recommend up to five ambulatory surgery centers. Additionally, participants were asked to rank quality, differentiating among these variables:
- Management in times of the COVID-19 crisis (e.g. safety of residents, hygiene measures)
- Management of waiting time (e.g. appointments)
- Quality of surgery preparations (e.g. consultation with doctor, information)
- Quality of surgical care (e.g. procedure)
- Quality of follow-up care (e.g. physical therapies)

The ranking is comprised exclusively of ambulatory surgery centers that are eligible regarding the above-mentioned scope. The ranking was created through an elaborate process. The information provided in this ranking should be considered together with other information about ambulatory surgery centers or, if possible, accompanied.
