A hospital performs 2,500 surgeries in a year. Using the lesson's statistic that surgical procedures account for approximately 22% of HAIs and the overall HAI rate is 3% of patients, estimate approximately how many HAIs in the hospital year are surgical-procedure-related. (Assume each surgery represents one hospital admission for this calculation.)

• A. Approximately 375 surgical HAIs because 15% of surgeries become infected by default.
• B. Approximately 17 surgical-procedure–related HAIs.
• C. Approximately 550 surgical HAIs, assuming 22% of admissions are surgical and all surgeries lead to HAIs.
• D. Zero surgical HAIs because modern surgery eliminates all infection risks.

Answer: (B)
