Budget impact analysis reveals walk-in fingertip HbA1c testing in community pharmacies could provide a significant...

In Japan, a new opportunistic community-based walk-in HbA1c testing program at pharmacies was enabled in 2014. An economic evaluation of this program from societal perspective has previously been published. This study examines the effect of a subsidy program for walk-in HbA1c-testing at community pharmacies in Japan on public health care expenditure by conducting a budget impact analysis from payer's perspective. The study focused on Adachi Ward in Tokyo, where a pioneering subsidy program was implemented. It examined the budget impact of the subsidy program over a 15 years. The total subsidy paid by the local authority during the first year was 2909 USD. Public expenditure remained positive for the first five years before becoming negative in the sixth year, eventually resulting in savings of 221,000 USD in the 15th year. The cost of treating type 2 diabetes that is detected early is offset by a reduction in expensive treatments for complicated cases. Subsidizing walk-in fingertip HbA1c testing in community pharmacies is likely to result in a significant reduction in public expenditure over the mid-to long term. Our result suggests that a similar strategy in other areas could also have a potentially favorable budget impact.
