Direct medical costs of diabetes and its complications in Vietnam: A national health insurance database study.

<bold>Aim: </bold>To estimate the direct medical cost of type 2 diabetes mellitus (T2DM) and its complications in Vietnam.<bold>Methods: </bold>Using the public payer perspective, the direct medical cost was estimated using routine data in the national claims database in Vietnam in 2017. People were identified as being diagnosed with T2DM if they were aged ≥ 30 years and who either (1) had at least one ICD-10 code E11 or (2) had been prescribed with oral antihyperglycemic medication on two separate visit records. The Diabetes Severity Complications Index was used to assess the presence of diabetes-related complications. All costs were standardized to 2017 United States dollars (USD).<bold>Results: </bold>Of the 1,395,204 people identified with T2DM, 55% had diabetes-related complications. The most common complication was cardiovascular diseases (34%). The total direct medical cost was USD 435 million, of which 24% was spent on hospitalization, 20% on outpatient care, 7% on emergency care, 36% on non-diabetes-related medication, and 13% on antihyperglycemic medication. About 70% of the total direct medical costs were attributed to diabetes-related complications.<bold>Conclusion: </bold>The high proportion of hospitalization and complications costs in Vietnam suggests that the possibility exists to make economic savings through better preventative care.
