Trial of Advance Care Planning (ACP) & Goals of Care Designations (GCD) Discussions

Background: Respecting patients' preferences for treatment is a key component of high quality end of life care. Alberta Health Services (AHS) has developed tools for public, patient and healthcare provider (HCP) engagement and education (such as guidebooks, videos, and HCP training modules) to support widespread engagement in advance care planning (ACP) and determining Goals of Care Designation (GCD). However, none of these knowledge translation (KT) tools have been validated and they have not been tailored to reflect barriers in the local context.

ACP is defined as a communication process where people plan for a time when they cannot make medical decisions for themselves. It includes thinking about and communicating their preferences for future healthcare, which can include conversations with family and healthcare providers, choosing and documenting an alternate decision maker, and/or documenting preferences for healthcare for use in the event that person loses capacity for medical decision-making. These discussions can occur both informally and formally. Goals of Care Designations (GCD) are medical orders of care that (a) serve as a communication tool for HCP to assist in rapid decision making; and (b) guide HCP and patients regarding the general intent and locations of care, and interventions that are to be provided. Decisions about goals of care usually arise over time through conversations between patients, family members and the health care team.

This randomized controlled trial (RCT) will focus on the two Conversations Matter Video decision-aids developed by AHS for people and their families. The first video is an 8-minute video that describes the 5-steps of the ACP process. The second video is a 8-minute video that illustrates the resuscitative, medical and comfort levels of care outlined in the Alberta GCD policy.

Scope: This protocol relates to two of the research activities designed to evaluate the impact of ACP/GCD. The first is an RCT to evaluate the effectiveness of two videos about ACP and GCD. Participants will be recruited from settings where ACP should ideally be occurring, and where data on ACP implementation is presently most lacking. The overall aim of the RCT is to evaluate and refine these existing knowledge translation (KT) tools to optimize the quality and frequency of patient education about and engagement in ACP and determining goals of care.

The second activity measures the economic impact of the Videos in these patient populations. A significant proportion of health care resources are consumed at end of life. ACP, which emphasizes discussions, combined with GCD, may have a greater impact than advance directives alone. To be clear, the primary goal of ACP is not about cost containment, but rather, to shift a culture of care toward a patient- and family-centered approach to medical decision-making. Prospective data collection and analysis will give insight into personal and intangible costs. It will allow for relatively precise measurement of health care savings, and thereby inform health care systems on anticipated savings and prescribe shift of funding necessary for appropriate resourcing in parts of the health care system that may see increased activity because of ACP, while also improving quality of patient-centred outcomes.

Methods: The RCT will be an in-person intervention and survey at baseline, follow-up telephone survey at one month and two months, and in-person survey at three months. At baseline, researchers will assess function and ask about demographic information, quality of life, advance care planning (ACP), and goals of care (GC) preferences and goals of care designation orders (GCD). Participants will then be randomized between two arms:

• control or "usual care"; and
• intervention whereby participant views two videos about ACP and GCD, respectively (Videos).

Surveys will be administered by research staff. The baseline intervention and survey will take approximately 30 to 65 minutes, depending on which arm the participant is randomized to, and be collected from up to 240 participants. At one, two and three months, follow up surveys will be administered to collect data about health care services utilized, health care costs incurred, and discussions about ACP and GC with their health care providers, lawyers, financial advisors and/or clergy in the preceding month. The one and two month surveys will be approximately 10-20 minutes in length. Three-month follow-up surveys will collect data about ACP, GC preferences and GCD and will be approximately 20-40 minutes in length. Researchers will also collect data from participants' electronic medical health records about their diagnosis and co-morbidities, health services utilization and costs at 12 months prior to baseline, baseline and approximately 12 months after baseline.

Objectives:

• Determine the effectiveness of the Videos by comparing the change from baseline to 1, 2 and 3 months of the number of participants who have had a conversation with a health care provider about ACP or GCD between two groups, namely: those who receive no intervention (usual care) and those who watch the Videos.
• Determine the cost and economic consequences of the Videos by comparing the change from 12 months prior to baseline to and including baseline, to 1 month, 2, months, 3 months and 12 months following baseline in health care utilization and costs between the two groups described in Objective 1.
