Factors influencing the hospitalization costs of patients with type 2 diabetes.

This study aims to research the factors influencing the hospitalization costs of patients with type 2 diabetes, so as to provide some references for reducing their economic burden. Based on the Hospital Information System of a 3A grade hospital in China, we analyzed 2970 cases with type 2 diabetes during 2005-2012. Both the number of inpatients and the hospitalization costs had increased in the study period. Using multiple linear regression analysis, we found that patients in Urban Employee Basic Medical Insurance had higher costs than those in New Rural Cooperative Medical Scheme. We also found hospitalization costs to be higher in male patients and older patients, patients who stayed more days at hospital and who had surgeries, patients who had at least 1 complication, and patients whose admission status was emergency. After standardizing the regression coefficients, we found that the hospital stay, the forms of payment, and presence of complications were the first 3 factors influencing hospitalization costs in our study. In conclusion, the hospitalization costs of patients with type 2 diabetes could be influenced by age, gender, forms of payment, hospital stay, admission status, complications, and surgery. Medical workers in the studied region should take actions to reduce the duration of hospital stay for diabetic patients and prevent relevant complications. What is more, medical insurance needs further improvement.
