  1. Patient density, nurse-to-patient ratio and nosocomial infection risk in a pediatric cardiac intensive care unit.

    Article - En anglais

    Background

    An investigation of a Serratia marcescens outbreak in a pediatric cardiac intensive care unit (CICU) suggested that understaffing or overcrowding might have been underlying risk factors.

    Objective

    To assess the effect of fluctuations in CICU nurse staffing levels and patient census on CICU nosocomial infection rate (NIR).

    Methods

    The monthly CICU nursing hours, patient days and nosocomial infections were obtained from retrospective review of administrative, patient and microbiology records during December, 1994, through December, 1995 (study period).

    The NIR and nursing hours : patient day ratio were then calculated.

    The correlations between NIR vs. nursing hours, patient days and nursing hours : patient day ratio were determined.

    Results

    The median monthly CICU NIR was 6.9 (range, 0 to 15.2) infections per 1000 patient days ; the median number of hours worked per month by CICU registered nurses was 7754 (range, 7133 to 8452) hours ; the median number of patient days treated per month was 507 (range, 381 to 590) patient days ; and the median monthly nursing hours :

    • The median monthly CICU NIR was 6.9 (range, 0 to 15.2) infections per 1000 patient days ;

    • the median number of hours worked per month by CICU registered nurses was 7754 (range, 7133 to 8452) hours ;

    • the median number of patient days treated per month was 507 (range, 381 to 590) patient days ;

    • patient day ratio was 15.2 : 1 (range, 13.2 : 1 to 19.9 : 1).

    The strongest linear correlation was observed between the monthly NIR and patient days (r=0.89, P=0.0001).

    There was an inverse correlation between the monthly NIR and nursing hours : patient day ratio (r=-0.77, P=0.003). (...)
