ABSTRACT
Background: Malnutrition in critically ill patients (confirmed by a negative caloric balance), has been associated with higher mortality.
Objectives: To determine the impact that has delayed start of nutritional support on morbi-mortality of patients in ICUs participating in the study.
Design: Prospective cohort in 12 ICUs of different public and private hospitals in Mexico City.
Subjects: 4,494 were included, 1,702 of them were disqualified due to incomplete information.
Methods: Demographic, APACHE II, Brussels and NEMS were collected. The population under study was divided in two groups: Group A start nutrition before 36 hours of their arrive at ICUs. Group B start nutrition after 36 hours of their arrive at ICUs. The statistical analysis consisted of bivariate and mutivariate analysis, considering significant a p ‹ 0.05.
Results: Statistically significant differences were observed in stay, co-morbidity acquired in ICUs and use of resources, in relationship to delayed in start nutrition. In the multivariate analysis was observed that delay in start nutrition for more than 36 hours, has a risk 1.6 times higher of mortality.
Conclusions: Delayed start nutrition support is associated with longer hospital stay, higher co-morbidity acquired in ICUs, higher consumption of resources and mortality.
