Correlation between nutric score and adequacy of energy and protein intake with duration of mechanical ventilation in the intensive care unit Dr. Kariadi Hospital, Semarang-Indonesia

Abstract

Background: Malnutrition in the ICU patients increases morbidity, mortality, cost, and mechanical ventilation (MV) duration. Nutric score has been validated as a screening tool in critically ill patients to identify patients at risk of malnutrition. The pathophysiology of malnutrition in critically ill is caused by severity of disease and inflammation resulting in hypercatabolism. Delivering protein-energy intake will reduce hypercatabolism and maintain lean body mass that affects outcome. The study aims to analyze the correlation between nutric score and adequacy of energy and protein intake with MV duration. Methods: This cross sectional study enrolled 65 subjects ≥18 years with mechanical ventilation in the ICU of Dr. Kariadi Hospital Semarang during May to July 2020. The nutric score was determined within 24-48 hours. Statistical analysis used correlation test. Results: The mean nutric score was 2.3 ± 1.49, duration of MV was 3.9 ± 4.44. There was significant correlation between nutric score and duration of MV (r = 0.685; p <0.001). The mean adequacy of energy intake was 1448.7 ± 235.87 and protein intake was 57.9 ± 11.94. There was significant negative correlation between adequacy of energy intake and MV duration (r=-0.246; p = 0.048). There was significant negative correlation between protein adequacy intake and MV duration (r=-0.34; p=0.006). Conclusion: Nutric score was correlated with duration of MV in the ICU patients. Adequacy of energy and protein intake had significant correlation with duration of MV.
