Direct non-medical and indirect costs of diabetes and its associated complications in Vietnam: an estimation using national health insurance claims from a cross-sectional survey.

ABSTRACT: OBJECTIVE:The prevalence of diabetes in Vietnam has increased from 2.5% in 2007 to 5.5% in 2017, but the burden of direct non-medical and indirect costs is unknown. The objective of this study was to estimate the direct non-medical costs and indirect costs due to type 2 diabetes mellitus (T2DM) and its associated complications among Vietnam Health Insurance System (VHIS) enrollees in Vietnam. DESIGN:The first phase was a cross-sectional survey of patients with T2DM. In the second phase, data from the previous phase were used to predict direct non-medical costs and presenteeism costs of VHIS enrollees diagnosed with T2DM based on demographic and clinical characteristics in 2017. The human-capital approach was used for the calculation of indirect costs. SETTING AND PARTICIPANTS:This study recruited 315 patients from a national hospital, a provincial hospital and a district hospital aged 18 or above, diagnosed with T2DM, enrolled in VHIS, and having at least one visit to hospitals between 1 June and 30 July 2018. The VHIS dataset contained 1,395,204 patients with T2DM. OUTCOME MEASURES:The direct non-medical costs and presenteeism were collected from the survey. Absenteeism costs were estimated from the VHIS database. Costs of premature mortality were calculated based on the estimates from secondary sources. RESULTS:The total direct non-medical and indirect costs were US$239?million in 2017. Direct non-medical costs were US$78?million, whereas indirect costs were US$161?million. Costs of absenteeism, presenteeism and premature mortality corresponded to 17%, 73% and 10% of the indirect costs. Patients incurred annual mean direct non-medical costs of US$56. Annual mean absenteeism and presenteeism costs for patients in working age were US$61 and US$267, respectively. CONCLUSIONS:The impact of T2DM on direct non-medical and indirect costs on diabetes is substantial. Direct non-medical and absenteeism costs were higher in patients with complications.
