ABSTRACTBackground: Prolonged length of stay in the intensive care unit (ICU) consumes about 50% of resources. Objective: To determine the risk factors and consequences of prolonged length of stay in the ICU. Setting: ICU of a private hospital, Mexico City. Design: Cohort and prolective study. Patients: Seventy-three patients were included. Methods: It was registered demographic, clinical diagnosis and therapeutic, and APACHE II, TISS-28, Glasgow and Brussel variables. Analysis was made with multiple logistic regression; significance was defined as p ‹ 0.05. Results: ICU stay was ≥ 6 days. Risk factors were: gender female OR 2.1 (CI95% 1.1-3.9), organ failure at admission (present or potential) OR 4.6 (CI95% 1.9-10.9) APACHE II > 10 OR 3.1 (CI95% 1.4-6.6) and TISS-28 › 25 OR 5.1 (CI95% 2.7-9.5). They have major frequency of morbidity (60%) and mortality (23%); p › 0.05. Conclusions: Prolonged intensive care is associated with hight mortality.
