INTRODUCTION: Nutrition is essential for health and healing, especially in the perioperative period. However, little is known about the nutritional intake of hospitalized patients in low and middle-income countries.This paper aimed to characterize the composition and quantity of food in acute care surgery patients at a tertiary referral hospital in Rwanda. METHODS: Acute care surgery patients were queried about nutritional intake during hospitalization from May 21, 2018, to June 3, 2018, for 100 patient days. Calorie and protein intake were estimated and compared to standards for an average Rwandan adult.RESULTS: Median daily calorie intake was 1472 kcal/day (Interquartile range (IQR): 662, 2116). The median daily protein intake was 45.99 g (IQR: 24.38, 70.22). Assuming a calorie need of 25 kcal/kg/day and a protein need of 1g/kg/day, this is 98.1% of the estimated daily calorie needs and 76.7% of estimated daily protein needs. Estimating higher energy needs for a surgical patient, the daily intake is 70.0-81.9% of calorie needs and 51.1-63.9% of protein needs. CONCLUSION: Overall, the calorie and protein intake for the average Rwandan acute care surgery patient were low compared to the needs of a 60 kg surgical patient. More education and accessibility to high-quality foods are needed to ensure adequate nutrition in the postoperative period to optimize clinical outcomes.
