COST-EFFECTIVENESS ANALYSIS OF TREATMENT OF TYPE 2 DIABETES: COMPARISON BETWEEN A PRIVATE CLINIC AND A PUBLIC HEALTH CENTER IN THE BANGKOK METROPOLITAN AREA

Abstract

This retrospective study analyzes the cost-effectiveness of type 2 diabetes treatment in a private clinic and a public health center of Bangkok Metropolitan Administration. Activity-Based Costing (ABC) is used for calculating the cost of treatment of type 2 diabetes at Phyathai Sithivej Clinic and Public Health Center 41 Khlong Toei. The data were collected from financial records of fiscal year 2014. In this study, effectiveness is defined as the proportion of the number of patient visits with a Hemoglobin A1c (HbA1c) test result of less than 7% per total number of patient visits which tested for HbA1c. The total cost of treatment of type 2 diabetes at Phyathai Sithivej Clinic in fiscal year 2014 was 583,602.28 Baht (3,224.32 Baht per patient per year). The total cost of treatment of type 2 diabetes at Public Health Center 41 Khlong Toei in fiscal year 2014 was 1,426,982.17 Baht (4,559.05 Baht per patient per year). The effectiveness of treatment of type 2 diabetes in fiscal year 2014 of Phyathai Sithivej Clinic and Public Health Center 41 Khlong Toei was 0.69 and 0.28, respectively. The cost-effectiveness of treatment of type 2 diabetes at Phyathai Sithivej Clinic was 4,672.93 Baht per one successful glycemic control per year and 16,282.32 Baht per one successful glycemic control per year at Public Health Center 41 Khlong Toei. However, these results have to be interpreted carefully as the results may be driven by factors such as differences in patients’ socio-economic status or differences in type 2 diabetes treatment.
