example 1
[0093] Example 1: Categorical variables for disease coding and population information
[0094]
[0095] Bacterial endocarditis complex group (ICD9 code)
[0096] The patient's basic demographic information and admission status variables (partial) are as follows:
[0097]
[0098]
[0099] S5: Within the same DRG cohort, statistically significant comorbidities and other categorical variables were pretreated by statistical tests for patient mortality, length of hospital stay, and cost.
[0100] S6: In the step of establishing a statistical model, regression analysis is performed on the model to quantify the degree of influence of variables;
[0101] Use the independent variables to quantitatively describe the predictive variables. In the disease risk adjustment, the predictive variables are patient mortality, hospitalization days and hospitalization costs, and the independent variables are combined complication variables and other variables; the regression analysis of ...
