THE ASSESSMENT OF THE RISK FACTORS OF THE NOSOCOMIAL SEPTICAEMIA IN PATIENTS HOSPITALIZED AT ADULTS INTENSIVE CARE UNITS
Abstract:
Nosocomial bloodstream infections occur frequently in Intensive Care Units and are associated with recognized and unrecognized risk factors. The impact of these infections in the evolution of the serious ill patient has been extensively studied, with an attributed mortality rate ranging from 19% to 35%. Our main objective was to investigate the risk factors for the bloodstream infection in patients hospitalized at an Intensive Care Unit from an emergency clinical hospital. A prospective study was undertaken over a period of 4 years and 9 months. The overall incidence of nosocomial bacteraemia was 9, 7/1000 admissions. A multivariate model showed that only three factors were significantly and independently responsible for nosocomial bacteraemia: the length of intravascular catheterization (P=0, 0077, OR = 1, 32), the presence of other nosocomial infections (P=0, 0015, OR=28, 67), the length of urinary catheterization (P = 0, 02, OR = 1, 12). These results show that the factors which had most influence on the development of nosocomial bacteraemia were those factors associated with the treatment received by patients during their hospital stay.
