Family caregiver grief and post-loss adjustment: A longitudinal cohort study

Existential distress among family caregivers of patients with advanced cancer: A systematic review and meta-analysis

OBJECTIVE

Caregiving for a loved one is challenging and requires significant resources. Existential distress in family caregivers may include hopelessness, demoralization, fear of death, pre-loss grief, or a sense of not being emotionally prepared. The aim of this systematic review is to synthesize the quantitative literature on existential distress among family caregivers of patients with advanced cancer, focusing on its prevalence, association with mental disorders, as well as with sociodemographic, disease, and treatment-related factors.

METHODS

We systematically searched electronic databases for quantitative studies of the above-described existential distress concepts in family caregivers of patients with advanced cancer. Two independent reviewers extracted data and evaluated study quality. Data were analyzed using random-effects meta-analysis.

RESULTS

We retrieved 17.587 records, of which 31 studies fulfilled inclusion criteria. 63% of the studies (n = 20) provided sufficient data for meta-analysis for 5558 patients. We found an overall pooled prevalence of 30.6% for existential distress, 95% CI [24.2-37.0]. For existential distress subconcepts, prevalence rates were 57.0%, 95% CI [37.8-76.2], for death anxiety, 13.9%, 95% CI [10.8-17.0], for demoralization, 24.0%, 95% CI [18.0-30.0], for pre-loss grief, 18.4%, 95% CI [4.0-32.7], for hopelessness, 35.2%, 95% CI [28.2-42.2], for loneliness, and 35.6%, 95% CI [13.0-58.3], for emotional unpreparedness.

CONCLUSIONS

Approximately one third of the respondents were affected by high levels of existential distress. The review provides evidence for further development of support services that can reduce existential distress, focused on death anxiety, and improve the quality of life for family caregivers of patients with advanced cancer.

An examination and proposed definitions of family members' grief prior to the death of individuals with a life-limiting illness: A systematic review

BACKGROUND

Research has extensively examined family members' grief prior to the death of an individual with a life-limiting illness but several inconsistencies in its conceptualization of related constructs, yet significant conceptualization issues exist.

AIM

This study aimed to identify and characterize studies published on family members grief before the death of an individual with a life-limiting illness, and propose definitions based on past studies in order to initiate conceptual clarity.

DESIGN

A mixed-method systematic review utilized six databases and was last conducted July 10, 2021. The search strategy was developed using Medical Subject Headings. This study was prospectively registered on PROSPERO (CRD42020166254).

RESULTS

One hundred thirty-four full-text articles met inclusion criteria. This review revealed across studies a wide variation in terminology, conceptualization, and characterization of grief before the death. More than 18 terms and 30 definitions have been used. In many cases, the same term (e.g. anticipatory grief) was defined differently across studies.

CONCLUSIONS

We found grief occurring before the death of a person with a life-limiting illness, which we termed pre-death grief, is comprised of two distinct constructs: anticipatory grief and illness-related grief. Anticipatory grief is future-oriented and is characterized by separation distress and worry about a future without the person with the life-limiting illness being physically present. Illness-related grief is present-oriented and is characterized by grief over current and ongoing losses experienced during the illness trajectory. These definitions provide the field with uniform constructs to advance the study of grief before the death of an individual with a life-limiting illness.
