[Experience and evaluation of studies on the prevalence of nosocomial infections at a general hospital].
From November 1986 to December 1987 we undertook 5 different counts of the prevalence of nosocomial infections (NI) in 4,572 patients (100% of the population). The following are the most important average values: NI overall, 14.4%, distributed as follows: urinary infections, 29.1%; surgical wounds, 21.6%; pneumonias 8.6%; phlebitis due to catheter insertion, 14.5%; and bacteremias, 5.2%. The most commonly found microorganisms were E. coli, S. aureus, Proteus mirabilis and Enterococcus. These studies reflect the need to decrease the prevalence of NI, mainly those coming from surgical wounds and from the urinary tract. These type counts are feasible with limited human resources. However, they are not appropriate for analyzing in detail the causes of the different types of NI nor in epidemic situations.
