The number of hospitals in the U.S. was roughly equal to the number of ASCs in 2016, according to Healthcare Real Estate Insights.
Here are six numbers to know:
1. As of 2016, there were about 5,532 surgery centers and 5,534 hospitals.
2. Between 2000 and 2016, the number of surgery centers grew 82 percent and the number of hospitals decreased 5 percent.
3. The number of surgeries performed in the outpatient setting reached two-thirds, up 30 percent from 1990.
4. About 61 percent of ASCs are single-specialty, with gastroenterology, ophthalmology and pain management as the leading specialties.
5. The six largest ASC operators manage 20 percent of all surgery centers. Most ASCs are at least partially physician-owned, and 64 percent are entirely physician-owned. Twenty-nine percent are joint ventures. Just 7 percent of ASCs are entirely owned by a hospital or corporate provider.
6. An average ASC is 15,447 square feet with three operating rooms.
