Infection in a multidisciplinary intensive care unit at the University Hospital of the West Indies

ABSTRACT

The records of 1,252 patients were reviewed to determine the incidence of infection, mortality and associated risk factors in our multi-disciplinary intensive care unit (MD-ICU) during the period 1977 to 1982. The infection rate and the mortality rate were 24 percent and 22 percent respectively. The mortality rate in the infected group was 25 percent. The infection rate was higher in the intra-abdominal and trauma group as compared to the cardio-thoracic group (P<0.05). The incidence of ICU-acquired respiratory tract infection (41 percent), wound infection (17 percent) and urinary tract infection (15 percent) was significantly different from non-ICU acquired infections (P<0.05). The commonest site of infection was the respiratory tract (37 percent). The incidence of infection was directly related to the duration of medical devices left in situ and the length of stay in the unit (more than seven days) (AU)
