Nosocomial pneumonia presents a diagnostic and therapeutic challenge in the care of critically ill patients. The present study was designed to determine as closely as possible the occurrence of nosocomial pneumonia in surgical intensive care unit (ICU) patients using clinical, radiographic, and bacteriological parameters in a prospective concurrent fashion. ⋯ Nosocomial pneumonia was initially suspected in 13% of this ICU population. Numerous clinical parameters clearly distinguished these pneumonia patients from others and they suffered a substantially higher mortality. However, within this pneumonia group, only half of the patients could be validated as truly having pneumonia using available clinical parameters. Nevertheless, those validated were indistinguishable in their clinical behavior from those who were not. This calls into question the need for elaborate and sometimes expensive investigations for diagnosis of nosocomial pneumonia.

Twenty-five percent of all nosocomial infections are wound infections. Professional guidelines support the timely use of preoperative prophylaxis for prevention of postoperative wound infections. Barriers exist in implementing this practice. IPRO, the New York State peer review organization, as part of the Health Care Financing Administration's Health Care Quality Improvement Program, sought to determine the proportion of patients receiving timely antibiotic prophylaxis for aortic grafts, hip replacements and colon resections in 44 hospitals in New York State. ⋯ Antibiotic prophylaxis was performed in 81% to 94% of cases, however, anywhere from 27% to 54% of all cases did not receive antibiotics in a timely fashion. By delegating implementation of ordered antibiotic prophylaxis to the anesthesia team, timing may be improved and the incidence of postoperative wound infections may decrease.
