Costs analysis of diabetes mellitus: A study based on hospital invoices and diagnosis related groups

Abstract Objectives DM (Diabetes mellitus) is a serious community health problem and considered a burden of disease for social security institutions, households, and society. The objective was to analyse the costs of inpatients with diabetes mellitus. Study Design This study has a descriptive, cross-sectional and retrospective research approach. Method In the study, diagnosis related groups (DRGs) related with diabetes mellitus were analysed with regard to hospital invoices and DRG costing. This is a retrospective study on 649 patients who were hospitalized with the diagnosis of Type 1 (83 patients) and Type 2 diabetes mellitus (566 patients) in the year of 2013 at Ankara Numune Education and Research Hospital in Turkey. The study included patients with diagnoses of “E10” Type 1 diabetes mellitus and “E11” Type 2 diabetes mellitus. Type 1 and Type 2 DM costs were calculated by examining inpatient treatment invoices of related patients. DM treatment costs were limited according to hospital services. Results The average age of diabetes mellitus patients in the study was 57.24 ±15.79 years old and the average length of stay for these patients was calculated as 9.56 ±10.35 days. The average amount of service activity invoice was calculated as $714.90 and average DRG amount was $1223.40 for 649 inpatients with the diagnosis of diabetes mellitus in 2013. A significant difference was found in average hospital costs between Type 1 and Type 2 diabetes mellitus patients. Conclusion Disease cost analyses in hospitals are required in order to prioritize healthcare services, use resources efficiently and decrease the financial burden of diseases on the society.
