Telemedicine Use Among Adults with Asthma in the United States, 2021-2022.

Introduction: While previous studies have mainly focused on the impact of telemedicine on asthma management, little is known about the disparities in the use of telemedicine among individuals with asthma. This study aimed to investigate the factors associated with telemedicine use among adults with asthma in the United States using a nationally representative survey. Methods: Data from the 2021 and 2022 National Health Interview Survey were used. The multivariable logistic regression model was conducted to identify the factors associated with telemedicine use among adults with asthma. Results: In 2021-2022, the prevalence of telemedicine use among adults with asthma was 47.7%. Females, individuals who were obese, current smokers, those with educational levels of college and higher, health insurance coverage, a usual place for care, a history of asthma attacks, and coronavirus disease 2019 were more likely to use telemedicine. Non-Hispanic blacks, residents in the Midwest, South, and nonmetropolitan areas were less likely to use telemedicine. Conclusions: Disparities in telemedicine use were found among several characteristics in adults with asthma. It is crucial to identify the vulnerable populations in accessing telemedicine and ensure equality in telemedicine use among patients with asthma.
