title: Operating room surveillance: a new approach in reducing hip and knee prosthetic wound infections.
abstract: A prospective study of surgical wound infections (SWI) in hip prosthesis surgery and total hip and knee replacements at two community hospitals with common surgical staffs was begun in May 1982. The rates of SWI during the first 7 months for four orthopedic surgeons were 9% (3/32) for hip prosthesis surgery and 16.7% (3/18) for total hip and knee replacement, with 12% (6/50) overall. To reduce infections, each orthopedic surgeon agreed to intraoperative surveillance (IOS) of two procedures (hip prosthesis or total hip or knee replacement) by the infection control nurse at each hospital. Significant IOS findings were too many persons in the operating room (five to nine persons), operating room doors opened frequently (25 to 50 times), inconsistent use of prophylactic antibiotics, and excessive conversation. In January 1984, IOS data and recommendations were shared with each orthopedic surgeon, the operating room staff, and the anesthesia personnel. Subsequently, a statistically significant drop in SWI was realized for total hip and knee replacement (1/36 versus 5/36, p = 0.05) and overall (3/73 versus 14/116, p = 0.05). The drop in SWI for hip prosthesis surgery was not statistically significant (2/37 versus 9/80, p greater than 0.10). IOS and individualized communication were effective in reducing SWI.
