Nutritional status significantly affects hospital length of stay among surgical patients in public hospitals of Northern Ethiopia: Single cohort study

Abstract

Objective: This study aimed to assess the effect of nutritional status on length of hospital stay in Northern Ethiopia. Result: Institutional based prospective cohort study was conducted among 324 admitted surgical patients. Length of hospital stay were significantly associated with duration of disease (Adjusted Hazard Ratio (AHR) = 3.7,95% Confidence interval (CI):2.35-5.82), history of surgery (AHR = 1.4, 95% CI 1.40, 95% CI 1.17-1.86), nutritional status (Body Mass Index (AHR = 1.38, 95% CI 1.28-1.51), Mid Upper Arm Circumference (AHR = 1.29, 95% CI 1.04-1.62)) and individual diet diversity score (AHR = 2.64, 95% CI 1.14-6.14). Screening of patients for malnutrition at admission and provision of dietary supplements based on their nutritional status is recommended.
