PurposeTo determine the effect of isolation rooms on the direct spread of nosocomial infections (NIs) owing to cross-colonization in a pediatric intensive care unit (PICU).Materials And MethodsThis 6-month comparative clinical study used retrospective data from 1992 (an open single-space unit) and prospective surveillance from 1995 (individual rooms) to assess the effectiveness of the latter design on the control of NIs in critically ill pediatric patients. Patients admitted to the PICU for at least 48 hours underwent a microbiologic survey.ResultsThe average number of NIs per patient was higher in 1992 (3.62 +/- 0.7, 78 patients) compared with 1995 (1.87 +/- 0.2, 115 patients). Bacterial NIs were caused by gram-positive cocci (33.3%) and aerobic gram-negative bacilli (66.6%). Fungemia in all cases was caused by Candida albicans. Similarly, length of stay was significantly higher in 1992 compared with 1995 (25 +/- 6 and 11 +/- 6 days, respectively; P <.05). There was a significant reduction of respiratory and urinary tract episodes of NI as well as catheter-related infections in the separate room arrangement.ConclusionsOur preliminary analysis suggests a possible beneficial effect of single isolation rooms in reducing NI rate in the PICU. Hence, the influence of room isolation on NIs in pediatric intensive care warrants further investigation.Copyright 2002, Elsevier Science (USA). All rights reserved.
