ConclusionsThe 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 practiceFor 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.
