Trends in Outpatient Telemedicine Utilization Among Rural Medicare Beneficiaries, 2010 to 2019.

IMPORTANCE

Little is known about how telemedicine use was evolving before the broad changes that occurred during the COVID-19 pandemic in 2020. Understanding prepandemic patterns of telemedicine use can inform ongoing debates on the future of telemedicine policy.

OBJECTIVE

To describe trends in telemedicine utilization among Medicare fee-for-service beneficiaries before the COVID-19 pandemic and the specialties of clinicians providing telemedicine.

DESIGN SETTING AND PARTICIPANTS

This was a cross-sectional study and descriptive analysis of telemedicine utilization by 10.4 million fee-for-service Medicare beneficiaries from 2010 to 2019. Data analysis was performed from June 6, 2019, to July 30, 2020.

MAIN OUTCOMES AND MEASURES

Rates of telemedicine utilization, characteristics of beneficiaries who received telemedicine in 2010 to 2019, and specialties of clinicians delivering telemedicine.

RESULTS

Of 10.4 million rural Medicare beneficiaries, telemedicine was used by 91 483 individuals (age ≥65 years, 47 135 [51.5%]; women, 51 476 [56.3%]; and White, 76 467 [83.6%] individuals) in 2019. In 2010 to 2019, telemedicine visits grew by 23.1% annually. A total of 0.9% of all fee-for-service rural beneficiaries had a telemedicine visit in 2019 compared with 0.2% in 2010. In 2019, there were 257 979 telemedicine visits or 34.8 visits per 1000 rural beneficiaries and most (75.9%) of these visits were for mental health conditions. Patients with bipolar disorder or schizophrenia (3.0% of rural beneficiaries) received 40% of all telemedicine visits in 2019. Some traditionally disadvantaged and underserved groups comprised a larger share of telemedicine users than nonusers in 2019, such as those dually insured with Medicaid (56.9% of users vs 18.6% of nonusers; adjusted odd ratio, 3.83; 95% CI, 3.77-3.89). In 2010 to 2019, telemedicine for mental health conditions shifted away from psychiatrists (71.2% to 35.8% of all telemedicine visits) to nonphysician clinicians, eg, nurse practitioners, psychologists, and social workers (21.4% to 57.2%). There was wide variation in telemedicine utilization in 2019 across counties: median (IQR), 16.0 (2.5-51.4) telemedicine users per 1000 beneficiaries). In 891 counties (29% of all US counties), at least 10% of beneficiaries with bipolar disorder or schizophrenia used a telemedicine service in 2019.

CONCLUSIONS AND RELEVANCE

In this cross-sectional study of telemedicine utilization before the COVID-19 pandemic, there was sustained growth in telemedicine visits among rural beneficiaries covered by the Medicare program, especially care delivered by nurse practitioners and other nonphysician clinicians. The prepandemic model of telemedicine provided in local health care settings may be a viable modality to maintain in rural communities.
