Nutritional assessment can early identify patients who are malnourished and at risk of malnutrition. To examine the effect of nutritional status on wound healing in elderly burn patients, we used the Mini-Nutritional Assessment-Short Form (MNA-SF) to measure the nutritional status of elderly patients. This study aimed to examine the role of MNA-SF in elderly burn patients through the correlation analysis of wound healing indicators and MNA-SF score. This was a prospective observational and cross-sectional study. This study used the MNA-SF to investigate the elderly burn patients at the department of burn. According to the score, the patients fell into three groups: good nutritional status (more than 12 points), malnutrition risk (8-11 points), and malnutrition (0-7 points). At the same time, we measured and compared the wound healing indicators among the three groups of patients, and detected the correlation. The results showed gender had a slight influence on the score of nutritional status, while age was negatively correlated with the MNA-SF score and nutrition-related indicators. There was a low positive linear correlation between the wound healing percent area change or wound healing rate of patients and the score of the MNA-SF. This study finds malnutrition is common among hospitalized elderly burn patients. The application of the MNA-SF in elderly burn patients is efficient and accurate to identify malnutrition early and prevent further obstruction of the normal wound healing, which can provide reference points for early nutrition intervention programs.
