Research objective: To investigate the extent to which telehealth visits mitigated COVID-19 pandemic-related impacts on in-person outpatient visits among Medicare beneficiaries, including those who are high-cost high-need. High-cost high-need patients were defined as those 65 years or older and with 2 or higher Hierarchical Condition Categories (HCC) scores.
Study design: A difference-in-difference design was used to estimate the change in outpatient in-person and telehealth utilization for the COVID-19 pandemic cohort compared to the control cohort in the prior year.
Population studied: Medicare patients from an Accountable Care Organization (ACO) were used as the study sample. The pandemic cohort was defined as those enrolled in the ACO in 2019-2020 (N = 21,361). The control cohort was defined as those enrolled in the ACO in 2018-2019 (N = 20,028). The study period was defined as April-September 2020 for the pandemic cohort and the same months in 2019 for the control cohort, with the preceding 12 months used as the baseline periods, respectively. Over 740,000 patient-month records were analyzed using logistic and negative binomial regressions. The models were adjusted for patient-level characteristics, including HCC scores, which reflect the complexity of patient health conditions and risk for future healthcare costs.
Principal findings: The total number of outpatient encounters (in-person and telehealth) in both primary and specialty care decreased by 41.5% in April 2020 compared to the pre-pandemic period. Telehealth comprised 78% of all outpatient encounters in April 2020 but declined to 22% by the end of September 2020. Only about 40% of all patients had at least one telehealth encounter between April-September 2020. Compared to the control cohort, the pandemic cohort experienced a monthly average of 113 fewer primary care encounters per 1000 patients (OR: 0.75, 95% CI: [0.73, 0.77]) and 49 fewer specialty care encounters (OR: 0.82, 95% CI: [0.80, 0.85]) over the six-month study period. This represented a decline of 25.6% and 17.3% in primary care and specialty encounters, respectively, among high-cost high-need patients. High-cost high-need patients or those with disabilities were more likely to use telehealth and experienced a lesser reduction in outpatient care utilization than other Medicare beneficiaries (OR: 1.20 and 1.06). Medicare beneficiaries with dual Medicaid coverage, those of non-white race/ethnic groups, and those living in rural/suburban areas were less likely to use telehealth and experienced a greater reduction in total outpatient care (OR: 0.86, 0.96 and 0.90).
Conclusions: While there was a substantial significant increase in telehealth use in April 2020, utilization declined significantly during the six-month study period, and did not fully mitigate the decline in in-person outpatient visits resulting from the COVID-19 pandemic. While high-cost high-need Medicare patients and those with disabilities were more likely to use telehealth, disparities in telehealth usage and reductions in outpatient care remain among low-income, non-white, and rural Medicare beneficiaries.
Implications for policy or practice: Older patients insured by Medicare, including those with high-cost high-need or disabilities were able to make use of telehealth services for outpatient visits during the COVID-19 pandemic. Health policies and interventions should target improving telehealth access and delivery for advancing sustainability and equity among Medicare beneficiaries.
