Abstract
We propose to pilot a randomized evaluation of strategies to facilitate advance directive completion in the 65+ patient population of our partner, Providence St. Joseph Health. Despite the significant economic and personal implications of end-of-life health care decisions, many people fail to document their wishes or to select a representative who can make medical decisions on their behalf. Descriptive evidence suggests that this results in sub-optimal outcomes including dissatisfaction and potentially unnecessary medical spending. However, it is not well understood why patients fail to engage in this apparently high-value planning. Our trial will pilot two interventions with roughly 5,000 patients, with intention to scale the evaluation to include over 70,000 patients across 64 clinics. We will evaluate the effects of (i) an in-person drive to facilitate advance directive completion, (ii) an informational video on advance directives that will be electronically distributed to patients, and (iii) the interaction of these two interventions. Key outcomes will include advance directive completion rates, decisions made on advance directive forms, and eventually observed care decisions. We will also leverage surveys and granular data on patient health to better understand barriers to advance care planning and relate to underlying economic theory that explains behavior.

Interventions
Intervention(s)
After the survey completion date, we will proceed with the interventions: (1) a series of Advance Directive Drives at one of the two selected clinics (Clinic A) and (2) a distribution of a link to an ACP Decisions video via email to a randomly selected 50% of patients with an email on file who meet the inclusion criteria in the two selected clinics (Clinic A and Clinic B). All patients in the two clinics with an email on file will be contacted with an email message and patients without an email will be contacted by paper letter.

Secondary Outcomes (explanation)
Experimental Design
Experimental Design
This pilot experiment will seek to answer the following research question: What is the impact of electronic provision of information (video and brochures from ACP Decisions) about end-of-life decision making (Intervention B) on whether a patient aged 65+ completes and uploads an AD to their electronic medical record (EMR), for patients who do not have an uploaded, complete AD at the beginning of the study?

Randomization of the video intervention will be done at the individual patient level, stratified by clinic, but limited to patients who have a unique email address on file and do not have an AD already uploaded to the EMR. Participants will not know whether they are part of a study (waiver of consent). In addition to ITT, will use randomization as an instrument for watching the video (defined as clicking through the link).

Experiment Characteristics
Sample size: planned number of clusters
Approximately 5000 patients 65+ across the two clinics, 13% have ADs already uploaded and 30% do not have an email on file, so the video intervention will be randomized across 2968 patients, stratified by clinic.
Sample size: planned number of observations
Approximately 5000 patients 65+ across the two clinics, 13% have ADs already uploaded and 30% do not have an email on file, so the video intervention will be randomized across 2968 patients, stratified by clinic.
Sample size (or number of clusters) by treatment arms
Clinic A- No Video: 814, Video: 815
Clinic B- No Video: 669, Video: 670
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
2.5 percentage point increase in ADs uploaded in 4 weeks after intervention outreach
