基于决策树的住院老年患者吞咽障碍风险预测模型的研究OA

Objective To construct a swallowing disorder warning model for elderly patients based on decision tree.Methods Convenience sampling was used to study 200 elderly patients admitted to the geriatric department of a tertiary comprehensive hospital in Yinchuan,Ningxia.Results Among 200 elderly patients,the incidence of swallowing disorders was 40.5%.The two groups of patients were compared in terms of gender,age,education level,occupation,medical insurance type,annual family income,daily living ability,frailty,depression,nutrition,and BMI(χ2 values were 13.321,4.064,31.944,36.695,18.230,19.681,52.509,10.253,20.456,9.070,9.483,respectively),and the differences were statistically significant(all P＜0.05).The decision tree model identified the main influencing factors of swallowing disorders in elderly patients as self-care ability,occupation,education level,and depression.The Receiver Operating Characteristic curve of the decision tree model had an area under the curve of 0.862,sensitivity of 79.8%,and specificity of 79.0%,P＜0.001.Conclusions A decision tree model based on self-care ability,occupation,education level,and depression can effectively predict the risk of swallowing disorders in elderly patients.
