Patient-Oriented Evidence That Matters
Advance Care Planning Increases Execution of Advance Directives and Surrogate Decision-Maker Assignment
Am Fam Physician. 2018 Dec 1;98(11):682-683.
Does advance care planning lead to increased completion of advance directives and selection of surrogate decision makers among frail older adults?
In this study, an intensive advance care planning intervention dramatically increased the completion of advance directives and the identification of surrogate decision makers. (Level of Evidence = 2b)
These researchers conducted a cluster randomized trial of facilitated advance care planning education or usual care among modestly frail older adults living in residential care homes or receiving home care nearby. The education intervention included trained facilitators and educational materials and tools intended to identify the patients' goals, values, and preferences regarding their health care and to assist in identifying a surrogate decision maker in the event of non-competence. In addition to assigning an activation score (not all that important), the researchers assessed whether the patients had documented their advance care preferences and had selected a surrogate decision maker. The researchers included 16 clusters that contributed 201 patients (between one and 53 patients per cluster). The patients in each group were in their mid-80s and most were female. The intervention patients were more likely to receive home-based care (61%) and to have completed high school (65%) than the control patients (49% and 40%, respectively). At the end of one year, 93% of the intervention group had completed an advance directive compared with 34% of control patients (number needed to treat [NNT] = 2; 95% confidence interval [CI], 2 to 3). Additionally, 94% of the intervention participants had identified a surrogate decision maker compared with 67% of the control patients (NNT = 4; CI, 3 to 6). The consultation sessions took an average of two hours, including travel time, to complete.
