Almost 75% of all surgery today is performed on an outpatient basis. In 1980, that figure was only 15%. Slightly more than half of all outpatient surgeries are done in an ambulatory surgery center.

In Texas alone, there are 569 ASCs (via Texas Health & Human Services).

There are 196,884 industry employees in the United States (via IBISWorld).

Common procedures in ASCs include cataract surgery, gallbladder removal, tonsillectomy, endoscopy/colonoscopy, and arthroscopic/orthopedic procedures, with cardiology being the fastest-growing specialty (via Avanza Healthcare Strategies). 

The annual median number of surgical cases per operating room is 1,104; of procedures per procedure room is 1,357; of orthopedic cases per room is 800; of ophthalmology cases per room is 1,400; and of gastroenterology cases per room is 1,500 (via Avanza Healthcare Strategies).

Sales for the industry came out to $1235 billion in 2021, and in the past three years, the sector has grown 5.2% annually (via Kentley Insights).

The ownership structure of ASCs can be broken down as follows: physician only - 60%, hospital-physician - 17%, corporate-physician - 13%, corporate only - 5%, hospital only - 3%, and other - 2% (via Avanza Healthcare Strategies).
