In a pediatric intensive care unit we conducted a 1-year prospective study of 454 patients to determine whether wearing a gown decreased the overall nosocomial infection rate, incidence of intravascular catheter colonization, breaks in handwashing technique, and traffic.
The overall infection rate was 26 (13%) of 198 admissions during the gown-wearing periods v 23 (9%) of 256 admissions for the periods when gowns were not worn (P < .25). Of 348 intravascular catheter tips cultured 16 (4.6%) were colonized during gown-wearing periods compared with 21 (6.3%) of 330 when no gowns were worn (P < .25). Of 78 patient contacts 54 (69%) were followed by no handwashing during gown-wearing periods and 59 (70%) of 84 contacts were followed by no handwashing during periods when no gowns were worn. The mean occurrence of visits per patient per hour and total visits per hour differed between gown-wearing and no-gown-wearing periods by analysis of variance, P < .01 and P < .005, respectively. Although traffic was decreased during periods of gown use, overgowns are an expensive, ineffective method of decreasing nosocomial infection rates, vascular catheter colonization rates, and breaks in handwashing technique.
