Differential Effects of an Integrated Community-Based End-Of-Life Support Team (ICEST) Model for Terminally Ill Older Adults on Spousal and Adult-Children Caregivers.

ABSTRACT

Backgrounds Family caregivers (FCs) play an essential role in delivering home-based end-of-life care. However, little is known about FCs'' experiences when undertaking this role. The integrated community end-of-life support team (ICEST) is a needs-driven, home-based, family-centered care model in Hong Kong. We evaluated its effects on FCs and compared outcomes for spouses and adult children. Method: A multicenter pre-post-test study was conducted. Eligible participants were primary FCs of terminally ill older adults (age ≥ 60) who had a life expectancy of ≤12 months. Baseline (T0) and three-month post-intervention (T1) outcome measures included FCs'' caregiving strain, psychological distress, perceived external support, intimate relationships, and communications regarding care planning. Results: A sample of 628 FCs were enrolled at T0, and 40.0% completed the T1 assessments. The ICEST model was effective in reducing caregiving strain, depression, and worries about patients, whilst there were improvements in agreement about care planning with patients, and perceived external supports. At T0, spouses held more negative perceptions of caregiving and faced fewer adjustment demands than adult children. Compared with spouses, adult children were more intimate with patients. Between T0 and T1, spouses experienced a greater reduction in worries about patients, than adult children. Conclusions: The ICEST model contributed to better outcomes, individually and relationally, for FCs, regardless of relationship type. Spouses and adult children faced different challenges while delivering home-based end-of-life care. Effective interventions should modify the negative perceptions of caregiving in spousal caregivers and enable adult children to deal with multiple tasks and complex expectations.
