Spirituality-Integrated Interventions for Caregivers of Patients with Terminal Illness: A Systematic Review of Quantitative Outcomes.

This systematic review of published quantitative research was conducted to explore the effects of spirituality-integrated interventions for informal caregivers of terminally ill patients. Multiple databases were searched for articles published between January 2004 and November 2019. Twelve randomized controlled trials were identified. Methodological quality was assessed using the revised Cochrane Collaboration's tool for assessing risk of bias. Studies were notably diverse in terms of spiritual background, intervention design, technology used, and outcomes measures. Spirituality-integrated interventions were found to show positive outcomes for caregivers. However, methodological flaws negatively affected the quality of most studies, warranting further and rigorous research into the topic.
