The majority of older adults with serious illnesses visit the ED near the end of life, yet most do not have advance directives. In the time-pressured ED environment, the lack of a feasible method to facilitate advance care planning (ACP) constrains our current practice. We sought to develop and refine a brief motivational interview (BMI) intervention for older adults to engage in ACP conversations with their primary outpatient clinician. We conducted iterative cognitive interviews to refine our BMI intervention. We adapted a well-established BMI intervention previously designed for alcohol dependence to empower older adults to seek ACP conversations with their primary outpatient clinicians. Using an expert panel consisting of palliative care researchers and BMI researchers, we created a prototype to meet the needs of older adults with serious illness. The prototype was refined using mock clinical encounters and iterative cognitive interviews. Emergency medicine clinicians administered the intervention to the patient family advisory council members (prior ED patients who volunteered to improve the care we deliver) and standardized patients. After the mock encounters, individual cognitive interviews were performed to understand both the clinician and patient perspectives. An acceptability Likert-scale survey was administered to all participants. The scripted text was refined based on participants’ inputs, and the iterative refinements were reviewed by a second, blinded, attending emergency physician and the expert panel to ensure feasibility in the ED and maintenance of BMI and serious illness communication principles. This process was deemed when >75% of participants rated the intervention acceptable. We conducted 16 mock clinical encounters with 11 attending emergency physicians, 3 physician assistants, and 7 patients. 71% of the clinicians were male. Clinicians had broad range of clinical experience (57% with <5 years, 7% with 5 to 10 year, and 36% with >10 years of experience after training). Patients were 50% male, including 3 standardized patients. The mean acceptability Likert scale (0 not acceptable, 1-4 somewhat unacceptable, 6-9 somewhat acceptable and 10 completely acceptable) was 7. Clinicians spent mean of 6.8 minutes administering the BMI intervention. Examples of refinement included explicit stating the need for goals of care in the setting of worsening serious illness, using patient-centered language, eliminating readiness numerical scale, focusing to prepare for ACP conversation at the follow-up outpatient visit, allowing administering clinicians to use their judgment to avoid redundancy, and including specific actionable items that patients can take home to prepare for their follow-up visit. Participants also recommended shortening the script in concern for time, including caregiver (if present), and offering an opt-out process for patients to refuse the intervention if necessary can further improve the intervention acceptability. An ED BMI intervention for ACP conversations has been developed and refined. This intervention may improve the rate of ACP conversations for older adults after leaving the ED. Further study is needed to understand how older adults in the ED perceive this intervention.
