Telehealth among Medicare Advantage beneficiaries with and without Alzheimer's Disease and Related Dementias (ADRD), 2018-2024: from pandemic-era surge to post-pandemic decline.
Observational study in BMC health services research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTelehealth has become a vital element of healthcare delivery, especially among Medicare Advantage (MA) beneficiaries. Yet its use among individuals with Alzheimer’s Disease and Related Dementias (ADRD) – a population with complex biopsychosocial needs – remains understudied.
methodsWe conducted an observational cohort study of MA beneficiaries aged 65 and older using Optum’s de-identified Clinformatics® Data Mart Database (January 2017–June 2024). A matched sample of enrollees with and without ADRD was constructed. Difference-in-differences and event study analyses were applied to evaluate adjusted differences in quarterly telehealth utilization before and after the 2020 Medicare telehealth policy expansion during the COVID-19 public health emergency. The primary outcome was a quarterly indicator of any telehealth use, defined among enrollee-quarters with any medical claim.
resultsAmong 421,131 MA beneficiaries, telehealth use increased sharply in Q2 2020 for both ADRD and non-ADRD groups, peaking at 33.9 and 30.6% respectively. Use declined and stabilized by 2021, remaining slightly higher among beneficiaries with ADRD by Q2 2024. Adjusted DiD analyses showed a small but statistically significant post-2020 increase in telehealth use for the ADRD group compared to the non-ADRD group (2.58 percentage points; p < 0.01), with the gap narrowing over time. LIMITATIONS: Findings are based on one national MA claims database and may not generalize to other populations or settings.
conclusionMA beneficiaries with and without ADRD rapidly adopted telehealth following the 2020 policy expansion. Although use was initially higher among those living with ADRD, utilization converged over time. As telehealth policy evolves, it is critical to address barriers for cognitively impaired populations.
