Abstract:

Objective To analyze and evaluate the hospitalization expense of patients with acute myocardial infarction before and after the implementation of single disease quality control in a tertiary grade A hospital in Shanghai and propose suggestions. Methods Medical records of discharged patients who had diagnosed with acute myocardial infarction between 2007 and 2013 were retrospectively analyzed. The socio-economic characteristics, disease diagnosis and treatment, and expense information on the first page of medical records were collected. Expenses before and after the implementation of single disease quality control were analyzed. The stepwise regression analysis was adopted to analyze the influencing factors of total hospitalization expense. Results After the implementation of single disease quality control (since 2010), the total hospitalization expense, medicine expenses, and surgery expenses decreased, while the examination and treatment expenses increased. The hospitalization time, operation, blood transfusion, gender, admitted after the implementation of single disease quality control, and transfer were major factors that significantly influenced the total hospitalization expense. Conclusion After the implementation of single disease quality control, the total expense of inpatient with acute myocardial infarction decreases and the structure of expenses tend to be rationalized. The hospitalization time and illness are major factors that significantly influence the total hospitalization expense. In the long run, we should further reduce the hospitalization time and improve the quality of medical services in order to decrease the total hospitalization expense of patients with acute myocardial infarction.

Key words: single disease quality management, acute myocardial infarction disease, inpatient expenses
