Objective To explore the predictive value of diet in peristomal moisture-associated skin damage.

Methods From November 2019 to September 2020, 362 patients with enterostomy were selected from Zhongshan Hospital, Fudan University, Fudan University Shanghai Cancer center, The First Affiliated Hospital of Naval Medical University and Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medical. All patients were followed up for 3 months. The diet types of patients were judged by general diet, soft diet, semi-liquid diet and liquid diet. The unified assessment guidance of PMASD was used to diagnose the outcome. Logistic stepwise regression was used to explore the predictive effect of diet on the risk of PMASD, and other predictors were included for correction.

Results Among the 329 patients who completed the 3-month follow-up, 141 (42.8%) had PMASD, among which 37 (26.2%) had general diet, 48 (34.1%) had soft diet and 56 (39.7%) had semi-liquid diet. Soft and semi-fluid diet were independent risk predictors of PMASD both before and after adjustment. The adjusted OR were 6.30 (95%CI 3.31-12.32, P < 0.001) and 8.99 (95%CI 4.47-18.81, P < 0.001) respectively. The AUC was 0.767 (95%CI 0.718-0.815) and 0.845 (95%CI 0.804-0.886) respectively.

Conclusions Dietary types can be used to predict the risk of PMASD. Compared with regular diet, soft diet and semi-liquid diet increased the risk of complications, and the risk of semi-liquid diet was higher than that of soft diet.
