Randomized Control Trial of Advance Care Planning in Primary Care

A Randomized Control Trial of an Advance Care Planning Intervention to Engaged Substitute Decision-makers in Primary Care

Sometimes people with health conditions become ill suddenly and can no longer speak for themselves and another person (such as a family member) will make health care decisions for them. This means it is important to think about your wishes and tell others about them. This is called advance care planning. When people have done advance care planning, if they become very sick and cannot speak for themselves they are more likely to get the kind of health care they want and it is easier for the people who make decisions for them. There are tools such as brochures, questionnaires, and videos that can help people learn about these things. This research is being to done to study whether using tools for advance care planning and goals of care discussions will improve how patients and their substitute decision makers do advance care planning. This study is a randomized trial. This means half of the people in this study will meet with someone at their family practice to talk about advance care planning and review some tools and half will get usual care (a Speak Up workbook). The study will 1) evaluate if reviewing the tools, and having help to complete them, helps patients and their substitute decision maker do advance care planning 2) if this intervention will encourage patients to talk to their family doctor about these issues.

In prospective and randomized trials, advance care planning (ACP) significantly improves outcomes including increased likelihood that clinicians and families understand and comply with a patient's wishes, reduces hospitalization at the end of life, results in less intensive treatments at the end of life (according to patients' wishes) and increases use of hospice services. Trials have not been done in primary care. In this project, we aim to determine the efficacy of a care pathway designed to increase the quality and quantity of ACP in patients and their substitute decision-makers in primary care. The study is a multi-site, patient-based, unblinded, randomized trial conducted in family practices in Canada. Participants will be patients who are determined by their physician to be able to benefit from ACP, and the patient's substitute decision-maker. Participant pairs will be randomized to immediate intervention (care pathway) or delayed (8-12 weeks). The intervention is guided use of tools and decision aids to clarify values and preferences for treatments in the event of serious illness or near end of life. The outcomes will be substitute decision-maker engagement in ACP (including self-efficacy for enacting the role), patient engagement in ACP, and decisional conflict.
