What is the post-surgical infection rate in ambulatory surgery centers (ASCs)?

• A. 0.5% to 1.0%
• B. 0.1% to 0.5%
• C. 1.5% to 2.5%
• D. 2% to 3%

Answer: (A)

Postoperative infection rates in ambulatory surgery centers reflect how effectively standard infection control practices work in outpatient settings. For clean, outpatient procedures, these infections are relatively uncommon, with a typical experience around the low single digits. The most representative range across surveillance data is 0.5% to 1.0%. This captures the everyday reality of ASCs: infections do occur, but at a relatively low rate thanks to meticulous sterile technique, perioperative prophylaxis when indicated, and careful patient selection and monitoring.

Other ranges tend to reflect special circumstances. Rates around 0.1% to 0.5% can occur for very low-risk, simple procedures, but they don’t represent the broader mix of ASC cases. Higher ranges, such as 1.5% to 2.5% or 2% to 3%, are more typical of higher-risk surgeries, longer procedures, or settings with more complex patients, and thus aren’t the best general estimate for ASCs.
