Abstract:
Objective:To compare the predictive performance of the Norton Pressure Ulcer Risk Assessment Scale and the OH Pressure Sore Assessment Scale on pressure injury in elderly stroke patients.Methods:From January to December 2021, convenience sampling was used to select 168 elderly stroke patients admitted to the Department of Neurology, Wuxi Second People's Hospital as the research subject. The Norton Pressure Ulcer Risk Assessment Scale and the OH Pressure Sore Assessment Scale were used to assess the risk of pressure injury in elderly stroke patients. The sensitivity, specificity, positive predictive value, negative predictive value, Youden index, and area under the receiver operating characteristic curve ( AUC) of each scale were calculated. The Kappa value was used to evaluate the consistency. Results:A total of 168 questionnaires were distributed, 160 valid questionnaires were recovered, and the valid recovery rate was 95.24%. The incidence of pressure injury in 160 elderly stroke patients was 9.38% (15/160) . The AUC of the Norton Pressure Ulcer Risk Assessment Scale was 0.805. When the total score was 12.5, the sensitivity, specificity, and Youden index of pressure ulcer prediction were 0.933, 0.559, and 0.492, respectively, with the highest predictive performance. The AUC of the OH Pressure Sore Assessment Scale was 0.803. When the total score was 5.5, the sensitivity, specificity and Youden index of pressure ulcer prediction were 0.933, 0.379, and 0.312, respectively, with the highest predictive performance. The Kappa value between the two scales was 0.588, and the difference was statistically significant ( P<0.05) . Conclusions:The Norton Pressure Ulcer Risk Assessment Scale was superior to the OH Pressure Sore Assessment Scale in predicting pressure injury in elderly stroke patients.
