Abstract TP72: Advance Care Planning Engagement May Increase Among Stroke Survivors: Results From The Prepare For Your Care Trial

Introduction: Despite their high risk of mortality, recurrent stroke, and dementia, stroke survivors underutilize ACP. In a non-prespecified subgroup analysis of a randomized trial to increase ACP, we compared the efficacy of the PREPARE for Your Care (PREPARE) plus an easy-to-read advance directive (AD) to an AD alone among stroke survivors. Methods: PREPARE is an interactive digital program with easy-to-read, state-specific ADs, and video stories. Stroke survivors in the PREPARE trial were identified using the International Classification of Diseases codes. The primary outcome was new ACP documentation in the electronic medical record after 12 months; secondary outcome was self-reported ACP completion of: (1) signing official papers naming a surrogate decision maker; (2) discussion of patients’ wishes with surrogates; (3) discussion of patients’ wishes with medical providers; and (4) an AD, scored 0-4. We calculated the change from baseline to 12-month follow-up. Mixed-effects regression models were used, adjusted for health literacy (adequate or limited), baseline ACP documentation, and clustering by physician. Results: Of 986 PREPARE trial participants, 91 (9.2%) were stroke survivors and 72 had complete data. The mean age was 64 years (SD, 6.8 years), 47% were women, 74% identified as a minority race/ethnicity, 40% were Spanish-speaking, 49% had limited health literacy, and 41% had ACP before enrollment. There was a trend toward greater ACP documentation in the PREPARE-arm (table). The PREPARE-arm had significantly greater increase in completed ACP elements than the AD-only arm. Discussion: The PREPARE program shows promise to engage ethnically diverse stroke survivors in ACP and should be studied further. Addition of stroke-specific content and engagement of acute stroke survivors in adaptations may increase the impact of the program.
