Summary:Background:Artificial intelligence (AI) promises to revolutionize hematology care.Patients undergoing inpatient allogeneic hematopoietic stem cell transplantation (HCT) often experience psychological consequences, some of which may be attributed to anxiety about how to optimally care for themselves when returning home.Care.coach Avatar TM is a tablet-based ‘human-in-the-loop’ virtual health assistant (VHA) that utilizes generative AI and deterministic software to provide psychosocial support and health coaching to inpatients. It has been shown to improve loneliness, depression, anxiety, hospital delirium, and falls in older adults in the hospital (Chi, Geriatr Nurs 2017; Bott, J Med Internet Res 2019). Methods: We adapted the care.coach Avatar TM VHA for inpatient HCT, designing an education program to prepare patients for safe return to the home setting. The VHA engages patients with reminders for hydration, medications, food, or activity; education modules adapted for HCT; playing games such as jeopardy, chess, blackjack, trivia, or bingo; playing the news or music; having free-form conversations; going through therapeutic activities and exercises; and practicing mindfulness and guided meditation. Avatar protocols were updated based on feedback from a structured focus group (n=10) of nurse navigators, inpatient HCT nurses, and HCT physicians at the Dana-Farber/Harvard Cancer Center that was convened to discuss perspectives on implementation of care.coach Avatar TM VHA for HCT. Seven HCT-specific educational modules were created. A feasibility pilot was then performed in 3 sequential cohorts of 6 patients receiving reduced intensity conditioning (RIC) HCT. In the first cohort, patients were given the VHAs without any recommendations for how long to use them. The second cohort was given a recommendation for 30 minutes per day, and the third cohort was offered a $20 gift card for completion of at least 4 modules. Responses were measured through patient surveys and engagement data analysis. The predefined retention rate for feasibility was 67%, a standard for introduction of a novel AI technology (Teresi, Med Care 2022). Dissatisfaction rate for the overall VHA experience was defined as responding “disagree” or “strongly disagree” with recommending the VHA to others. Results: The study included 18 patients, with a majority female (61%) and white (72%; Table). The median age of the patients was 63 (interquartile range [IQR] 56-66). The retention rate from enr
