A Primary Care Telehealth Pilot Program to Improve Access: Associations with Patients' Health Care Utilization and Costs.

Background: The Veterans Health Administration (VHA) piloted an innovative video telehealth program called Virtual Integrated Multisite Patient Aligned Care Teams (V-IMPACT) in fiscal year (FY) 2014. V-IMPACT set up one regional "hub" site where primary care (PC) teams provided regular PC through telehealth services to patients in outlying "spoke" sites that experienced gaps in provider coverage. We evaluated associations between clinic-level adoption of V-IMPACT and patients' utilization and VHA's costs for primary, emergency, and inpatient care. Materials and Methods: This observational study used repeated cross-sections of 208,612 unique veteran patients assigned to a PC team in 22 V-IMPACT spoke sites from FY2013 to FY2018. V-IMPACT adoption in a spoke site was indicated if more than 1% of patients assigned to PC in a site used V-IMPACT services during the year. Association between V-IMPACT adoption and outcomes were assessed using mixed-effects models. Results: V-IMPACT adoption was associated with increased telehealth visits for PC (incidence rate ratio [IRR] = 2.42 [1.29 to 4.55]) and for primary care mental health integration (IRR = 7.25 [2.69 to 19.54]). V-IMPACT adoption was not associated with in-person visits, or with total visits (in-person plus video telehealth). V-IMPACT adoption was also not associated with acute hospital stays, emergency department visits, or VHA costs. Conclusions: Programs such as VHA's V-IMPACT can increase telehealth visits for PC, allowing successful transition across modalities and facilitating continuity of care without impacting total care. Programs should track substitution of in-person visits with telehealth visits and examine its effects on patients' health outcomes, satisfaction, and travel costs.
