Advance care planning for older adults in community-based settings: An umbrella review.

ABSTRACT

BACKGROUND: Advance care planning (ACP) is critical to ensure better quality end of life care, and older adults are often a target of ACP. However, ACP interventions and their outcomes are neither standardised nor conclusive. OBJECTIVES: To synthesise existing ACP systematic reviews and identify the types and outcomes of ACP interventions for older adults in community-based settings. METHODS: An umbrella review of systematic reviews. The Joanna Briggs Institute Reviewer's Manual was followed. Relevant systematic reviews were searched by utilising bibliographic databases, grey literature sources, and manual searches between April and July, 2019. Nine systematic reviews met the inclusion criteria. Critical appraisal on the selected reviews was conducted. Data were independently extracted using a data extraction tool by two researchers and synthesised based on consensus. RESULTS: The systematic reviews suggest the critical features of ACP interventions for older adults in community-based settings including clinicians' face-to-face communication with patients and their family members, comprehensive and individualized decisional aids, a proper intensity of ACP interventions, and professional training. When categorising ACP outcomes according to Sudore et al.'s (Journal of Pain and Symptom Management, 55, 2018, 245) framework, action outcomes (e.g., documentation, discussion) were frequently measured with positive outcomes. Quality of care outcomes such as congruence with care preference and healthcare outcomes such as health status were not reported sufficiently. CONCLUSIONS: The reviews suggested essential features of ACP interventions, which were often omitted in ACP interventions for older adults. Although the outcomes were generally positive, it is inconclusive as to whether ACP interventions eventually improved quality of end of life care or health status of older adults in community-based settings. IMPLICATIONS FOR PRACTICE For ACP interventions to be effective and comparable in their outcomes, we recommend adopting the key intervention components identified in this study. As the effects of ACP interventions are inconclusive, further investigations are warranted.
