[Temporal trends in nosocomial infections in a unit of pediatric cardiac surgery (1984-1988)].
We have evaluated the variations and the evolution of the temporal trends of cumulative incidence of hospital infections, their different localizations and causative organisms in a hospital ward and intensive care area from a pediatric cardiac surgery unit during the period 1984-1988. We also evaluated the effectiveness of our control and surveillance program by calculating from monthly records the cumulative incidence of monthly ad yearly rates of hospital infections and their localizations. The cumulative yearly incidence showed a decreasing trend (CI x 100 = 4.30-0.492 years) (SE, beta = 0.144; p less than 0.001), mainly owing to the reduction in urinary tract infections (CI x 100 = 6.93-1.426 years) (SE, beta = 0.452; p less than 0.001) and other infections (CI x 100 = 1.1-0.232 years) (SE, beta = 0.062; p less than 0.01). The most commonly isolated pathogens were E. coli, Pseudomonas sp and K. pneumoniae. The patients from that unit had a low risk of hospital infection during the 1984-1988 period, and this risk decreased concomitantly with the development of the program.
