Effectiveness of initiating advance care planning among older outpatients through intervention by physicians trained in a model discussion video: A randomized controlled trial

Aim This study aimed to assess the impact of a physician‐led intervention on advance care planning (ACP) introduction among older outpatients using a model discussion video. Methods This prospective interventional study included Japanese general practice outpatients aged ≥65 years. All participants received an ACP leaflet. Co‐researchers were trained using a model discussion video based on the “Serious Illness Conversation Guide,” and provided ACP introduction explanations to the intervention group to ensure intervention content consistency. The control group received the ACP leaflet only, with no standardized explanations. The primary outcome was ACP discussion occurrence. Secondary outcomes included ACP engagement (assessed through the 4‐item ACP Engagement Survey), engagement score for advance directives acquisition and score for surrogate decision‐maker identification, and anxiety incidence (assessed through Generalized Anxiety Disorder‐7). Results This study included 48 participants: 25 (52.1%) in the intervention group and 23 (47.9%) in the control group. Regarding primary outcome, the intervention group had significantly more ACP discussions compared with the control group (92.0% vs 26.1%, adjusted odds ratio 50.2, P = 0.0012). Regarding secondary outcomes, the intervention group showed greater readiness (mean scores for the 4‐item Engagement Survey [P = 0.0001], engagement score for advance directives acquisition [P = 0.01] and score for surrogate decision‐maker determination [P = 0.03]) than the control group, without increasing anxiety. Conclusions This physician‐led ACP introduction for older patients in a Japanese general practice setting enhanced ACP readiness and stimulated discussions, without increasing anxiety. The model discussion video for ACP introduction might effectively train physicians in general practice settings. Geriatr Gerontol Int 2024; 24: 859–866. The introduction of advance care planning to older patients in a Japanese general practice by physicians trained in a model discussion video based on the Serious Illness Conversation Guide increased advance care planning readiness and stimulated advance care planning discussions without inducing anxiety.
