Background: Guidelines recommend Advance Care Planning (ACP) for seriously ill older adults to increase the patient-centeredness of end-of-life care. Few interventions target the inpatient setting. Objective: To test the effect of a novel physician-directed intervention on ACP conversations in the inpatient setting. Design: Stepped wedge cluster-randomized design with five 1-month steps (October 2020–February 2021), and 3-month extensions at each end. Setting: A total of 35/125 hospitals staffed by a nationwide physician practice with an existing quality improvement initiative to increase ACP (enhanced usual care). Participants: Physicians employed for = 6 months at these hospitals; patients aged = 65 years they treated between July 2020–May 2021. Intervention: Greater than or equal to 2 h of exposure to a theory-based video game designed to increase autonomous motivation for ACP; enhanced usual care. Main measure: ACP billing (data abstractors blinded to intervention status). Results: A total of 163/319 (52%) invited, eligible hospitalists consented to participate, 161 (98%) responded, and 132 (81%) completed all tasks. Physicians’ mean age was 40 (SD 7); most were male (76%), Asian (52%), and reported playing the game for = 2 h (81%). These physicians treated 44,235 eligible patients over the entire study period. Most patients (57%) were = 75; 15% had COVID. ACP billing decreased between the pre- and post-intervention periods (26% v. 21%). After adjustment, the homogeneous effect of the game on ACP billing was non-significant (OR 0.96; 95% CI 0.88–1.06; p = 0.42). There was effect modification by step (p < 0.001), with the game associated with increased billing in steps 1–3 (OR 1.03 [step 1]; OR 1.15 [step 2]; OR 1.13 [step 3]) and decreased billing in steps 4–5 (OR 0.66 [step 4]; OR 0.95 [step 5]). Conclusions: When added to enhanced usual care, a novel video game intervention had no clear effect on ACP billing, but variation across steps of the trial raised concerns about confounding from secular trends (i.e., COVID). Trial Registration: Clinicaltrials.gov; NCT 04557930, 9/21/2020.
