However, patients who lack access to technology may be left behind in these initiatives. In 2016, the US Department of Veterans Affairs (VA) began distributing video-enabled tablets to provide video visits to veterans with health care access barriers. OBJECTIVE This study aimed to evaluate veterans' experiences with VA-issued tablets and identify patient characteristics associated with preferences for video visits vs in-person care. METHODS A baseline survey was sent to the tablet recipients, and a follow-up survey was sent to the respondents 3 to 6 months later. Multivariate logistic regression was used to identify patient characteristics associated with preferences for care, and we examined qualitative themes around care preferences using standard content analysis methods for coding the data collected in the open-ended questions. RESULTS Patient-reported access barriers cens in access to care, perceived differential quality of care, feasibility of obtaining necessary care, and technology-related challenges. CONCLUSIONS Many recipients of VA-issued tablets report that video care is equivalent to or preferred to in-person care. Results may inform efforts to identify good candidates for virtual care and interventions to support individuals who experience technical challenges. ©Cindie Slightam, Amy J Gregory, Jiaqi Hu, Josephine Jacobs, Tolessa Gurmessa, Rachel Kimerling, Daniel Blonigen, Donna M Zulman.
