■ 要旨
A general practitioner (GP) system is not available in Japan. During the COVID-19 pandemic, many patients with suspected COVID-19 were not accepted at many healthcare facilities, leading to the need to consider a GP system. However, the discussion about this system has been limited to the provider side, but not to the demand side. We investigated association between past visits to healthcare facilities and acceptance at healthcare facilities for COVID-19 diagnosis using a claims database provided by DeSC Healthcare, Inc. The database included 422,992 patients with a COVID-19 diagnosis, of which 300,194 patients with 1 year of observation period before the diagnosis (defined as baseline period), ≥1 hospital visit(s), and no inpatient during the baseline period were analyzed. Patients who visited healthcare facilities more often during the baseline period more often received the first COVID-19 diagnosis in the facilities; however, 30%–40% of patients with ≥24 visits months (total number of months to all facilities) during the baseline period received their first COVID-19 diagnosis in facilities not visited during the baseline period. Among patients who receive their first COVID-19 diagnosis at a facility not visited during the baseline period, the most frequently attended medical facility for most patients, approximately 86.5%, was a facility with <20 beds. From the results, we found that even patients who frequently visited medical facilities and had doctors who could be considered their family doctors were not accepted by the facilities. This situation may lead the expectation of the GP system. Further discussion would be needed, considering the demand from the population.
