Abstract Background The first state of emergency for coronavirus disease 2019 (COVID-19) in Japan was imposed from April to May 2020. During that period, people were urged to avoid non-essential outings, which may have reduced their access to health care. Methods Using health-care claims data from a city in Fukuoka prefecture, Japan, we conducted a retrospective cohort study of the state of emergency’s impact on patients’ medical visits to orthopedic clinics and their associated health-care expenditures. These measures were compared between 2019 and 2020 using a year-over-year analysis and unpaired t-tests. Results The analysis showed that medical visits in 2020 significantly decreased by 23.7% in April (P < 0.01) and 17.6% in May (P < 0.01) when compared with the previous year. Similarly, monthly outpatient health-care expenditure significantly decreased by 2.4% (P < 0.01) in April 2020 when compared with April 2019. In contrast, the health-care expenditure per capita per visit significantly increased by 1.5% (P < 0.01) in June 2020 (after the state of emergency was lifted) when compared with June 2019. Conclusion As orthopedic clinics in Japan are reimbursed using a fee-for-service system, the increases in per capita expenditures after the state of emergency may be indicative of physician-induced demand. However, we posit that it is more likely that a post-emergency increase in anti-inflammatory and analgesic treatments for spondylopathies, low back pain and sciatica induced a temporary rise in these expenditures.
