Abstract：Objective The comprehensive score of treatment quality of AMI patients was calculated and empirical Logit transformation was performed. To obtain the factors affecting the quality of treatment, To provide data support for the improvement of treatment quality.Methods The data of AMI patients were collected, the treatment quality of AMI patients was evaluated with 11 indexes, and the comprehensive scores of index utilization rate and treatment quality of patients were calculated. The empirical Logit transformation was carried out for the comprehensive score to obtain the transformation value of the comprehensive score for statistical description. The target variable was taken as the comprehensive score of the empirical Logit transformation, and the linear regression model was used to analyze the influencing factors of treatment quality.Results In this study, 4 137 AMI patients were collected. The highest utilization rate was the use of clopidogrel during hospitalization, and the lowest was the 12-lead ECG before hospitalization. The comprehensive score of the empirical Logit transformation followed the normal distribution. The maximum value of the comprehensive score of the outpatient admission was 0.705 4±0.645 5, and the minimum value of the hospitalization days 7 days and below was 0.194 3±0.605 1. The analysis results of influencing factors of treatment quality showed that the treatment quality was poor in older age, emergency admission, infarction location in the lower wall and multi-wall. The quality of treatment was better in admission during the weekend, increased hospital stay and hospitalization expenses, and fewer complications.Conclusion Linear regression was used to analyze the influencing factors of comprehensive score of treatment quality, the normality of comprehensive score of treatment quality should be considered from the data point of view, and Logit transformation of data is suggested. In order to improve the treatment quality of AMI patients, attention should be paid to patients who are older, hospitalized in emergency, admitted during working days, and have more myocardial infarction sites, more complications and shorter hospitalization time.
