The annual financial impact of adopting DOACs for treating VTE in a Thai healthcare setting was estimated using a budget impact analysis. The budget impact was calculated with a 5-year time horizon and the 6-month medication treatment costs. The incidence of VTE patients and the number of Thai people aged over 60 years were used to estimate the annual number of VTE patients in Thailand. As there were no reports of VTE incidence in Thailand, the incidence of VTE from an Asian country was used [51 (link)]. The 5% DOAC uptake rate was assumed to calculate the number of VTE patients receiving DOACs each year. The assumption was consistent with a previous budget impact analysis study [52 (link)]. The inputs for the budget impact are presented in Table S2 in the Additional File.
