BackgroundThe COVID-19 pandemic disrupted delivery of health care services worldwide. We examined the impact of the pandemic on clinics participating in the Veterans Affairs (VA) Clinical Resource Hub (CRH) program, rolled out nationally in October 2019, to improve access to care at under-resourced VA clinics or "spoke" sites through telehealth services delivered by regional "hub" sites.ObjectiveTo assess whether the CRH program was associated with increased access to primary care, we compared use of primary, emergency, and inpatient care at sites that adopted CRH for primary care (CRH-PC) with sites that did not adopt CRH-PC, pre-post pandemic onset.DesignDifference-in-difference and event study analyses, adjusting for site characteristics.Study CohortA total of 1050 sites (254 CRH-PC sites; 796 comparison sites), fiscal years (FY) 2019-2021.InterventionCRH Program for Primary Care.Main MeasuresQuarterly number of VA visits per site for primary care (across all and by modality, in-person, video, and phone), emergency care, and inpatient care.ResultsIn adjusted analyses, CRH-PC sites, compared with non-CRH-PC sites, had on average 221 additional primary care visits (a volume increase of 3.4% compared to pre-pandemic). By modality, CRH-PC sites had 643 fewer in-person visits post-pandemic (- 14.4%) but 723 and 128 more phone and video visits (+ 39.9% and + 159.5%), respectively. CRH-PC sites, compared with non-CRH-PC sites, had fewer VA ED visits (- 4.2%) and hospital stays (- 5.1%) in VA medical centers. Examining visits per patient, we found that CRH-PC sites had 48 additional telephone primary care visits per 1000 primary care patients (an increase of 9.8%), compared to non-program sites.ConclusionsVA's pre-pandemic rollout of a new primary care telehealth program intended to improve access facilitated primary care visits during the pandemic, a period fraught with care disruptions, and limited in-person health care delivery, indicating the potential for the program to offer health system resilience.© 2023.
