Abstract
BACKGROUND: Understanding the mix of video versus audio telehealth modality is critical to informing care for low-income safety net clinic patients. Our study examined whether telehealth modality and continued use of telehealth varied by rurality and whether that changed over time. METHODS: Encounters from adults in the OCHIN national network of primary care safety net clinics were identified by encounter type (in-person vs telehealth) and telehealth modality (video vs audio) from 4/1/2021 to 3/31/2023. Our main outcome was an interaction between patient rurality (defined using Rural Urban Commuting Area codes) and time. Linear probability models with clinic fixed effects were used to estimate predicted probabilities. RESULTS: The predicted probability of a telehealth visit decreased from 37.9% to 24.7% among urban patients (P <.001) and remained stable (29.5%-29.8%; P = .82) among patients in small rural areas. By March 2023, telehealth use among patients in small rural areas was 5.1 percentage points higher than among urban patients (P = .02). The predicted probability of an audio-only visit ranged from 63.5% to 70.5% for patients across all levels of rurality, but no significant differences by rurality or time were found. CONCLUSIONS: Safety net clinic patients were more likely to use audio-only than video telehealth visits. Telehealth in urban and large rural areas decreased since the first year of the pandemic. By the end of the study, patients in small rural communities used significantly more telehealth than urban patients. Elimination of reimbursement for audio telehealth visits may exacerbate existing health care inequities.
