Family Appraisal of Caregiving in a Brain Cancer Model:

Psychometric properties of carer-reported outcome measures in palliative care: A systematic review

BACKGROUND

Informal carers face many challenges in caring for patients with palliative care needs. Selecting suitable valid and reliable outcome measures to determine the impact of caring and carers' outcomes is a common problem.

AIM

To identify outcome measures used for informal carers looking after patients with palliative care needs, and to evaluate the measures' psychometric properties.

DESIGN

A systematic review was conducted. The studies identified were evaluated by independent reviewers (C.T.J.M., M.B., M.P.). Data regarding study characteristics and psychometric properties of the measures were extracted and evaluated. Good psychometric properties indicate a high-quality measure.

DATA SOURCES

The search was conducted, unrestricted to publication year, in the following electronic databases: Applied Social Sciences Index and Abstracts, Cumulative Index to Nursing and Allied Health Literature, The Cochrane Library, EMBASE, PubMed, PsycINFO, Social Sciences Citation Index and Sociological Abstracts.

RESULTS

Our systematic search revealed 4505 potential relevant studies, of which 112 studies met the inclusion criteria using 38 carer measures for informal carers of patients with palliative care needs. Psychometric properties were reported in only 46% (n = 52) of the studies, in relation to 24 measures. Where psychometric data were reported, the focus was mainly on internal consistency (n = 45, 87%), construct validity (n = 27, 52%) and/or reliability (n = 14, 27%). Of these, 24 measures, only four (17%) had been formally validated in informal carers in palliative care.

CONCLUSION

A broad range of outcome measures have been used for informal carers of patients with palliative care needs. Little formal psychometric testing has been undertaken. Furthermore, development and refinement of measures in this field is required.

Conceptualising psychological distress in families in palliative care: Findings from a systematic review

BACKGROUND

Adult palliative care patients and their family members experience significant psychological distress and morbidity. Psychosocial interventions adopting a systemic approach may provide a cogent model to improve the psychosocial care of families in palliative care. To facilitate design of these interventions, the construct of psychological distress in families in palliative care should be empirically derived.

AIM

To ascertain how psychological distress is conceptualised in families receiving palliative care.

DESIGN

A systematic review of the literature; this was followed by a thematic analysis and narrative synthesis.

DATA SOURCES

Using pre-defined search terms, four electronic databases (MEDLINE, CINAHL, PsycINFO and Behavioural Sciences collections) were searched with no date restrictions imposed. Pre-determined inclusion and exclusion criteria were then applied.

RESULTS

A total of 32 papers were included in the review. Two findings emerged from data synthesis. First, distress is conceptualised as a multi-dimensional construct but little consensus exists as to how to capture and measure distress. Second, distress in the families within these studies can be conceptualised using a tiered approach, moving from individual non-interactive depictions of distress through gradations of interaction to convey a systemic account of distress within the family system. Thus, distress shifts from a unitary to a systemic construct.

CONCLUSION

Currently, there is a paucity of research examining distress informed by family systems theories. This review proposes that distress in families in palliative care can be conceptualised and illustrated within a tiered model of distress. Further research is merited to advance current explanatory frameworks and theoretical models of distress.

Systematic review of supportive care needs in patients with primary malignant brain tumors

In adults, primary malignant brain tumors (PMBT) are rare, but they have a devastating impact and the chances for survival are limited. UK clinical guidance on supportive care for patients with brain and central nervous system tumors was published in 2006 and relied on very limited evidence. The current article reviews literature from 2005 through 2011 on the psychosocial and supportive needs of patients with PMBT and their families or caregivers. Searches were conducted in PubMed, Web of Science, Psychinfo, Cochrane, Scopus, ASSIA, and Sciencedirect. The search initially yielded 6220 articles, of which 60 were found to be eligible (1%). Eleven qualitative and 49 quantitative studies are reviewed here and mapped onto the structure of the existing UK clinical guidance. Studies suggest rates of depression and anxiety up to 48% in patients and up to 40% in caregivers, with many unmet needs and dissatisfaction with health care provider communication and information. Cognitive deficits increase as the disease progresses, hampering communication and decision-making. A range of neurological and physical symptoms at the end of life need recognition. Some successful supportive and neuropsychological interventions are reported. Although the volume of available studies has increased since UK guidance, many remain observational in nature, with few trials of interventions. However, this review provides an up to date resource for clinicians involved with patients with PMBT, describing current knowledge on patients' psychosocial needs, the type of care which has been found to be beneficial, and highlighting areas where more research needs to be done.
