Effect of an End-of-Life Planning Intervention on the completion of advance directives in homeless persons: a randomized trial.

BACKGROUND: Few interventions have focused on improving end-of-life care for underserved populations, such as homeless persons. OBJECTIVE: To determine whether homeless persons will complete a counseling session on advance care planning and fill out a legal advance directive designed to assess care preferences and preserve the dignity of marginalized persons. DESIGN: Prospective, single-blind, randomized trial comparing self-guided completion of an advance directive with professionally assisted advance care planning. (ClinicalTrials.gov registration number: NCT00546884) SETTING: 8 sites serving homeless persons in Minneapolis, Minnesota. PARTICIPANTS: 262 homeless persons recruited between November 2007 and August 2008. INTERVENTION: Minimal, self-guided intervention consisting of advance directive forms and written educational information versus a one-on-one advance planning intervention consisting of counseling and completing an advance directive with a social worker. MEASUREMENTS: Rate of advance directive completion, assessed by inspection of completed documents. RESULTS: The overall completion rate for advance directives was 26.7% (95% CI, 21.5% to 32.5%), with a higher rate in the counselor-guided group (37.9%) than in the self-guided group (12.8%) (CI of adjusted difference, 15.3 to 34.3 percentage points). This difference persisted across all sites and most subgroups. The advance directive's 4 clinical scenarios found a preference for surrogate decision making in 29% to 34% of written responses. LIMITATIONS: Sampling was limited to a more stable subset of the homeless population in Minneapolis and may have been subject to selection bias. Modest compensation to complete the preintervention survey could have influenced participants to complete advance directives. CONCLUSION: Both a simple and complex intervention successfully engaged a diverse sample of homeless persons in advance care planning. One-on-one assistance significantly increased the completion rate. Homeless persons can respond to an intervention to plan for end-of-life care and can express specific preferences for care or a surrogate decision maker, but additional studies are needed to assess the effect of these directives on subsequent care.

Engaging homeless persons in end of life preparations.

BACKGROUND: There are no prospective studies that have investigated the effects of an intervention to improve end of life (EOL) care in an underserved population. OBJECTIVE: To determine whether homeless persons will complete an advance directive (AD). DESIGN: Randomized trial comparing two modes of providing an opportunity for homeless persons to complete an AD. Half of the subjects were randomized to a self-guided group (SG) who were given an AD and written instructions; the other half were given the same material but, in addition, were offered the opportunity to receive guidance to complete the AD (CG). PARTICIPANTS: Fifty-nine homeless persons recruited from a drop-in center. MEASURES: Rate of AD completion and baseline and 3-month follow-up EOL-related knowledge, attitudes, and behaviors. RESULTS: The overall AD completion rate was 44%, with a statistically significant higher completion rate of 59% in the CG group compared to 30% in the self-guided only group. Frequency of worry about death decreased among those who filled out an AD from 50% to 12.5%, and also among those who did not (25% to 12.5%) (p < .05). Among those who filled out an AD, there were increases in plans to write down EOL wishes (56% to 100%; p < .05) and plans to talk about these wishes with someone (63% to 94%; p < .05). CONCLUSION: This study demonstrates that people living in dire economic and social situations will complete an AD when offered the opportunity. While offering guidance resulted in higher rates of completion; even a simple self-guided AD process can achieve completion of ADs in this population.
