AMBULATORY SURGERY: 48 million procedures U.S. total

Effect of the Great Recession on utilization

Another reason that ambulatory surgery visit estimates could have decreased and ambulatory surgery procedures remained steady, could be the deep economic recession that began in 2007.  By 2010, when NHAMCS began gathering ambulatory surgery data in both hospitals and [ambulatory surgery centers], the economy had not fully recovered. (p. 5)

The U.S. National Center for Health Statistics provides nationally representative estimates of the utilization of hospital-based ambulatory surgery and non-hospital-affiliated ambulatory surgery centers.  These statistics are based on a sample survey that is taken occasionally, not every year.  Statistics have been published recently for 2010.

Why has ambulatory surgery increased over the years?

  • Improvements in anesthesia/analgesia
  • Development of minimally invasive techniques
  • Medicare reimbursement changes

How many ambulatory surgery procedures in 2010?

  • 25.7 million (53 percent) in hospitals
  • 22.5 million (47 percent) in independent ambulatory surgery centers
  • 48.3 million (100 percent) total ambulatory surgery procedures

Who pays?

  • The primary payer is private insurance (51 percent of visits)
  • Next is Medicare (31 percent)

How long are ambulatory surgery visits [duration]?

  • 57 minutes (average operating room time)
  • 33 minutes (surgical time)
  • 70 minutes (postop time)
  • There are more granular data showing the difference between hospitals and independent ASCs for this measure
