Abstract Background: Recently, the importance of nutritional management in pressure ulcer control has been pointed out. In this study, we analyzed the relationship between nutritional indicators and the presence or absence of pressure ulcers in order to reveal the importance of nutritional management in pressure ulcer control. Method: We investigated 407 inpatients for blood tests, height, weight, BMI, the Ohura-Hotta (OH) scale, nutrition method, living independence, and the presence or absence of pressure ulcers. Results: In the comparison of patients with and without pressure ulcer, significant differences were found in gender, nutrition method, serum total protein, serum albumin, hemoglobin concentration, and the OH scales. Multiple logistic regression analysis showed that gender, intravenous nutrition, serum albumin levels, and the OH scale were associated with the presence or absence of pressure ulcers. The results suggest that not only the OH scale, but the nutritional support was also important in the prediction of the pressure ulcer. It was suggested that shifting from intravenous feeding to tube feeding or oral feeding is important. Conclusion: we found that pressure ulcer was related to gender, intravenous nutrition, serum albumin level and the OH scale. The importance of nutritional management for pressure ulcer prevention was confirmed.
