Resumen

Introduction: The critically ill patient is one who is physiologically unstable and under life-threatening. The background of studies in our country and in Latin America evidence a high nutritional risk in inpatients. On the other hand, the hospital stay allows us to know hospital efficiency; a prolonged stay generates the increase in costs, the poor accessibility to hospitalization services, the saturation of emergency rooms and the risks of adverse events. Objective: To evaluate the association between the nutritional risk and the length of stay of adult patients in the Intensive Care Unit of a National Hospital in Lima, 2023. Material and methods: Non-experimental cross-sectional and correlational-causal study. The population was made up of patients from the critical area during the period 2023. A sample of 100 medical records was obtained. The nutritional risk was determined using the NUTRIC score tool. The sum of the responses obtained was categorized the nutritional risk into low risk 0-5 points and high risk 6-10 points. The ICU stay was calculated by the length of stay in days, and was classified as short hospital stay (less than 10 days) and long hospital stay (greater than or equal to 10 days). The data were analyzed using the Kendall Tau inferential statistic, due to the fact that the variables of research were categorized into nominal data (sex) applied into X2. Results: It was found that 61% of the studied population had a low nutritional risk and 39% had a high risk. 53% of the patients had a short stay and a median of 12 days in the ICU, also it was found a low association (coefficient 0,192), but significant between the variables nutritional risk and the stay in ICU. The age presented a low association (coefficient 0,303), but significant with the nutritional risk. According to the sex, was not observed the association between the variables ICU stay and nutritional risk. Conclusions: In the present study, it was found the association between the nutritional risk variables and the hospital stay in ICU patients, however, the association with the sex was not found.
