COVID-19, Telemedicine, Telehealth, Pandemic

Due to the pandemic of the novel coronavirus (COVID-19), the government announced a state of emergency and quarantine, which gained interest in telemedicine from both patients and health care workers. However, there is no study in Japan about investigating the population-level interest in telemedicine and COVID-19 pandemic.
We used confirmed COVID-19 cases and web search volume of “telemedicine” in Japanese. Pearson’s correlation coefficient was used to measure the association. Time-lagged correlation analysis was performed for potential time-lag and a sensitivity analysis was performed to consider potential confounders.
We found a correlation (r=0.610) between each other with strongest correlation obtained after two days the press release (r=0.765). This study demonstrated the population-level interest in telemedicine increases with the trend of confirmed COVID-19 cases in Japan.
