Nutritional factors and pressure injury risk in hospitalised patients post-stroke.

ABSTRACT

OBJECTIVE: This study aimed to analyse the nutritional factors and pressure injury (PI) risk in hospitalised patients post-stroke. METHOD: The research employed a descriptive observational method in which patients ≥18 years of age were followed for six days. Nutritional evaluation was based on anthropometric and dietary factors. The nutritional risk was assessed via anthropometric measurements, Braden nutrition subscale and daily dietary intake. PI risk was evaluated through the Braden Scale. The Wilcoxon test, paired t-test, and Kruskal-Wallis test were applied and corrected with Bonferroni correction or analysis of variance, followed by the post hoc Tukey test. RESULTS: During their hospital stays, the participating 59 patients had an increase in sensory perception (p=0.02) and nutrition (p=0.005) scores. It was observed that patients at high risk of PI did not meet daily nutritional recommendations for calories, proteins, carbohydrates, lipids and micronutrients (zinc, selenium and copper) compared with patients at low-to-moderate risk. Weight (p<0.001), body mass index (p<0.001), calf (p=0.01) and arm (p=0.04) circumferences, and subscapular (p=0.003) and triceps (p<0.001) skinfolds decreased during the six days of hospitalisation. CONCLUSION: From the findings of this study, it was concluded that nutritional factors, such as unmet recommended daily nutritional requirements of macronutrients and micronutrients, and nutritional status are associated with a higher risk of developing a PI.
