Background: Malnutrition is widely accepted as an independent risk factor for hospitalization, even more so admission at the intensive care setting. This study attempts to assess the adequacy of nutritional intake among adult intensive care unit patients admitted at the Manila Doctors Hospital from January 1, 2016 to June 30, 2016 and to determine the relationships between adequacy of intake and selected variables namely mortality, length of hospital stay, and baseline nutritional status. This is a retrospective cohort study.
Materials and Methods: All adult patients admitted at the Manila Doctors Hospital Intensive Care Unit from January 1, 2016 to June 30, 2016 were enrolled in this study. Baseline demographics were obtained. Adequacy of nutritional intake was determined by computing for the total caloric and total protein requirement and comparing this daily with the actual intake. In cases of poor intake factors affecting adequacy were noted and tallied. Odds ratio was used to determine the relationship between adequacy of intake versus mortality and length of hospital stay. The difference in actual intake and requirement(bothcaloricandprotein)werecomparedusingpairedt-test.Fishers’exacttestwasused to compare adequacy of intake versus baseline nutritional status.
Results:154 patients were included in this study. There was a significant difference between the nutritional prescription and actual intake with an average difference of 435 kcal and 18g protein less than the prescription. 59.09% of patients had adequate caloric intake while 59.74% had adequate protein intake. Patients with inadequate intake were found to have shorter length of hospital stay, but this was not statistically significant. Computing for the odds ratio of adequacy of intake versus mortality showedthatpatientwithinadequatecaloricintakewere3.49xmorelikelytoresultinmortality, likewise patients with inadequate protein intake were 3.01x more likely to result in mortality. No significant relationship was found between baseline nutrition status and adequacy of intake.
Conclusion: The majority of patients in the intensive care unit of Manila Doctors Hospital had adequate intake and this appears to reduce mortality.
