Abstract

Diabetes mellitus (DM) requires long-term therapy. Selection of the right therapy was very important to provide optimal results at an affordable cost. One of the main standards of oral antidiabetic therapy prescribed for type 2 DM (T2DM) is metformin, either alone or in combination therapy. The purpose of this study was to describe the direct medical costs in type 2 DM patients between metformin and metformin-glimepiride therapy. This research was an observational and descriptive. Demographic and clinical data were taken prospectively from the complete medical records of data patients with the main diagnosis of DM who fulfilled the inclusion criteria in the period January 2019–November 2020 at RSU Nene Mallomo Sidenreng Rappang, South Sulawesi and the two Public Health Centers namely Puskesmas Galur. II and Panjatan II Kulon Progo Yogyakarta. Cost data includes total medical costs from the hospital/ healthcare perspective (cost of drugs, doctor's services and checkups, fees for checking Fasting Blood Glucose/ Gula darah Puasa (GDP) and Blood Glucose Level While/ Gula Darah Sewaktu (GDS)) and total costs from the Badan Penyelenggara Jaminan Sosial (BPJS)/ payer perspective (INA-CBG's rates) were covered by insurance. The results showed that the average direct medical costs at the hospital and the two Public Health Centers respectively were metformin therapy in IDR (Indonesian Rupiah) namely IDR 120.736 and IDR 9.072,- and metformin-glimepiride therapy of IDR 126.298,- and IDR 18.634,-. It can be concluded that the average direct medical cost of metformin therapy is lower than metformin-glimepiride therapy.

Abstract

Metformin and metformin-glimepiride are cost-effective therapy options and are most commonly prescribed to treat type 2 diabetes mellitus (DM). This study aims to determine the cost-effectiveness of using metformin and metformin-glimepiride in patients with type 2 DM at Nene Mallomo Sidenreng Rappang General Hospital. This analytical descriptive observational research employed a retrospective cohort design. The data of type 2 DM patients, new and old patients, were obtained from the medical record unit. The target population was data of outpatients for the period January-December 2019. The parameter of the therapeutic effectiveness is the random blood sugar levels of the patients after receiving treatment. The data on cost from the hospital perspective were obtained from the administration and finance unit. Cost-effectiveness analysis employed calculations of the average cost-effectiveness ratio (ACER) and the incremental cost-effectiveness ratio (ICER). Meanwhile, the risk ratio (RR) employed the analytical chi-squared method to determine the relationship between the two types of therapies and their effectiveness. This study has revealed that 30 patients met the inclusion criteria; 14 patients received metformin therapy and 16 patients received metformin-glimepiride therapy. Metformin therapy is more effective (64.29%) and more costly (IDR120,736). The metformin's ACER value is 1877.99, and its ICER value is -3107.26. The cost-effectiveness analysis has revealed that metformin therapy is more cost-effective than metformin-glimepiride therapy. Meanwhile, the chi-squared analysis has discovered no relationship between the two therapies and their effectiveness. The RR value of 1.080 concludes that metformin has 1.080 as much therapeutic effectiveness as the metformin-glimepiride.
