Community-based HbA1c testing programme for early detection of undiagnosed diabetes in community pharmacy.

Objective: Testing with fingertip blood sampling, including HbA1c testing, has been available in community pharmacies in Japan since 2014. In 2016, the Mihara Pharmacy Association in Hiroshima Prefecture, in collaboration with the Mihara municipal government, developed a community programme that utilized the walk-in HbA1c test that could be offered by participating community pharmacies. The aim of this study was to assess whether the new programme could detect undiagnosed DM in the community and to compare groups who had and had not accessed the SHCG programme among SHCG eligible participants.

Method: The programme includes pharmacist advice following participants conducted Hba1c testing in the pharmacy, and completing a questionnaire to collect self-reported personal data including lifestyle, demography, height, weight, and blood pressure. All those accessing the programme were included. We analysed data from fiscal years 2016 to 2018, obtained retrospectively from the questionnaires.

Key findings: The participants aged 40-74 years who were the target of a national health check programme represented 73.7% of the 1933 total unique participants. Approximately 40% of these participants did not undergo routine checkups, 23.8% had HbA1c scores ≥5.6%, and 2.7% had HbA1c scores ≥6.5%.

Conclusions: The walk-in HbA1c community testing programme provided an opportunity to test the diabetes mellitus risk of residents, especially those who have missed their routine checkups. If the community programme were adopted widely, more undiagnosed populations at risk for diabetes mellitus could be detected in the early stages and the use of community resources such as pharmacists and pharmacies would be utilized.
