OBJECTIVES: Budget Impact Analysis (BIA) is a key component of HTA and requires reliable estimates of the target patient population. Practical methodological approaches are needed to support BIA development in the context of evolving epidemiological data. This study aimed to explore how clinical expert engagement is used within Ukrainian HTA to support BIA and adapt epidemiological inputs to the national healthcare context.
METHODS: A descriptive methodological review of Ukrainian HTA conclusions was conducted by the HTA Department team. Conclusions were analyzed to identify the data sources used to construct BIA. Data sources were categorized as official national statistics, registry-based data, extrapolated international epidemiological data, or input from clinical experts of specialized healthcare institutions. The use of clinical expert input was examined as a practical methodological approach to support BIA development and to substantiate key model assumptions in the Ukrainian HTA context.
RESULTS: In approximately 20% of the analyzed Ukrainian HTA conclusions, BIA incorporated extrapolated international epidemiological data as the main source of information. In these cases, clinical experts from specialized healthcare institutions were engaged to inform assumptions related to target population size, facilitating adaptation of epidemiological inputs to the national healthcare context.
CONCLUSIONS: Engagement of clinical experts from specialized healthcare institutions represents a practical methodological approach to support assumptions regarding target population size in BIA within the Ukrainian HTA system. This approach enables adaptation of international epidemiological data to the national healthcare context and contributes to the robustness and credibility of BIA results. These findings underscore the value of structured expert engagement in emerging HTA systems.
