OBJECTIVE: To evaluate the information-seeking behaviour of pharmacists during the COVID-19 pandemic and its relation to COVID-19 and related infections and deaths within the local prefecture. DESIGN: Ecological study. SETTING: Japan-47 prefectures. METHODS: The number of accesses to a Japanese web page established by the Pharmacy Informatics Group to disseminate information about infection control and the number of infections and deaths in 47 prefectures were investigated from 6 April to 30 September 2020 using the access information on the web page and publicly available information. RESULTS: During the first 6 months of the COVID-19 pandemic, the total number of accesses was 226 130 (range: 10 984-138 898 per month), the total number of infections was 78 761 (1738-31 857) and the total number of deaths was 1470 (39-436). The correlation between the total number of accesses and that of infections per 100 000 individuals in 47 prefectures was r=0.72 (95% CI 0.55 to 0.83, p<0.001), and between the total number of accesses and deaths per 100 000 individuals in 47 prefectures was r=0.44 (95% CI 0.17 to 0.65, p=0.002). CONCLUSIONS: The information-seeking behaviour of community pharmacists correlated positively with infection status within the community.
