Over 23 mo., 1233 patients with nosocomial urinary tract infections (UTI) were identified among 40,718 consecutive admissions by using a standardized, prospective system of hospital-wide surveillance. Nosocomial bloodstream infections (BSI) occurred in 565 patients, 32 of whom had BSI originating from UTI, for an attack rate of 2.7/100 patients with nosocomial bacteriuria. Patients with UTI due to Serratia marcescens were most likely to develop secondary BSI (rate, 16/100) compared to patients with nosocomial UTI due to other organisms (rate, .ltoreq. 4.3/100; P < 0.05). The median interval between documentation of UTI and of secondary BSI was 24 days for patients with infections due to S. marcescens compared to 1 day for the entire group (P < 0.005). Risk factor analysis indicated that men with UTI were more likely to develop secondary BSI than were women (P < 0.05). Intensified infection control efforts are particularly necessary with high-risk groups such as bacteriuric men, especially among those patients with UTI due to s. marcescens, to reduce the incidence of secondary, hospital-acquired BSI.
