To analyze the influencing factors of medical expenses of middle-aged and elderly patients with coronary heart disease complicated with comorbidities based on machine learning model.
A total of 3 002 patients with coronary heart disease complicated with complications hospitalized in the 27 public hospitals in a provincial capital city in central China was selected as subjects from January 2022 to January 2023.The patient data were collected.The influencing factors of medical expenses of middle-aged and elderly patients with coronary heart disease complicated with comorbidities were analyzed based on four machine learning models,namely ridge regression,Lasso regression,random forest,and decision tree.
Compared with other models,the random forest model had better fitting effect.The material cost(27.72%) and western medicine cost(19.43%) accounted for relatively high proportion of the patient's medical expenses,while the nursing cost(4.02%) and consultation cost(1.15%) accounted for relatively low proportion.The hospitalization days,the level of medical institution(tertiary hospital),gender(female),age(>50~70 years old), discharge department(cardiology),admission department(cardiology),and common complication(hypertension) were the main influencing factors of medical expenses of middle-aged and elderly patients with coronary heart disease complicated with comorbidities.
Managers should formulate effective measures according to the influencing factors of medical expenses in middle-aged and elderly patients with coronary heart disease with complication to eliminate the waste of medical resources and reduce the burden of middle-aged and elderly patients with coronary heart disease complicated with comorbidities.
