A systematic review of process evaluations for psychosocial interventions designed to improve the wellbeing and quality of life of community-dwelling people with dementia and their carers.

ABSTRACT:

Background

Psychosocial interventions improve the wellbeing and quality of life of People Living with Dementia (PLWD) and their family carers; but due to their complexity it can be challenging to identify mechanisms of action. We reviewed process evaluations that have sought to elucidate how these interventions work, to inform their implementation.

Method

We systematically reviewed process evaluations of studies evaluating psychosocial interventions for PLWD in their own home and/or their family carers. We rated study quality using the Mixed Methods Appraisal Tool. We described, with reference to Medical Research Council (2015) process evaluation guidance, how implementation, mechanisms of impact and contextual factors were investigated; and describe commonalities in the mechanisms of action identified across studies.

Results

Twenty four included studies evaluated the processes of 22 interventions. These studies collectively applied five frameworks; almost all frameworks' advised evaluations were theory-based and used mixed-methods analyses, but only 5/24 evaluation designs were informed by the intervention theory and 8/24 used mixed methods. 8/24 evaluations considered contextual factors in their design, though 20/24 cited contextual factors in findings. Interventions were more successful where PLWD were motivated and aware of potential benefits, and when carers could support engagement and were themselves supported by the intervention. How the intervention aligned with participants' current needs and stage of dementia were key influencing factors.

Conclusion

Knowing how interventions can influence change for community-dwelling people with dementia and their family carer's will improve translation of trial findings into practice. Robust, theory-driven process evaluations can enable this.

Project description:ObjectiveTo implement and evaluate co-designed interventions to improve communication of positive newborn bloodspot screening results and make recommendations for future research and practice.DesignA process evaluation underpinned by Normalisation Process Theory.SettingThree National Health Service provider organisations in England.ParticipantsTwenty-four healthcare professionals (7 newborn screening laboratory staff and 24 clinicians) and 18 parents were interviewed.InterventionsThree co-designed interventions were implemented in practice: standardised laboratory proformas, communication checklists and an email/letter template.Primary outcome measuresAcceptability and feasibility of the co-designed interventions.ResultsAuditing the implementation of these interventions revealed between 58%-76% of the items on the laboratory proforma and 43%-80% of items on the communication checklists were completed. Interviews with healthcare professionals who had used the interventions in practice provided positive feedback in relation to the purpose of the interventions and the ease of completion both of which were viewed as enhancing communication of positive newborn bloodspot screening results. Interviews with parents highlighted the perceived benefit of the co-designed interventions in terms of consistency, pacing and tailoring of information as well as providing reliable information to families following communication of the positive newborn bloodspot screening result. The process evaluation illuminated organisational and contextual barriers during implementation of the co-designed interventions in practice.ConclusionVariations in communication practices for positive newborn bloodspot screening results continue to exist. The co-designed interventions could help to standardise communication of positive newborn screening results from laboratories to clinicians and from clinicians to parents which in turn could improve parents' experience of receiving a positive newborn bloodspot screening result. Implementation highlighted some organisational and contextual barriers to effective adoption of the co-designed interventions in practice.Trial registration numberISRCTN15330120.

Project description:BackgroundWhile there is a clear need for psychosocial interventions that promote the well-being of carers of patients with cancer, the corresponding evidence base is disparate, complex, and difficult for end users to navigate and interpret. Carers remain undersupported with a lack of dedicated, effective, evidence-based programs. We will conduct a meta-review to synthesize this evidence and determine the state of science in this field.ObjectiveThis study aims to address the question, "what psychosocial interventions are available to promote the well-being of carers for people with cancer?"MethodsA meta-review will synthesize the relevant reviews of psychosocial interventions that have been developed and evaluated with carers for people with cancer. A total of 4 electronic databases (PsycInfo, MEDLINE, CINAHL, and Cochrane Database of Systematic Reviews) will be searched for reviews published between January 2013 and December 2023. A team-based approach will be taken for screening and assessment of the returned records against the eligibility criteria to determine inclusion. Included reviews will be critically appraised using the Joanna Briggs Institute Critical Appraisal Checklist for Systematic Reviews and Research Syntheses. Relevant data on study characteristics, carer and patient populations, intervention details, and psychosocial outcomes will be extracted, synthesized, and the findings will be presented in a narrative format.ResultsIt is anticipated that the study will be completed by October 2024.ConclusionsEnsuring that carers have access to evidence-based programs that promote their well-being as they care for loved ones is critical. This meta-review will contribute to program development and translation efforts by providing a clear picture of the intervention evidence base of carers of patients with cancer and identifying notable strengths, weaknesses, and gaps across the literature. The findings are anticipated to offer future directions to advance research in the field.Trial registrationPROSPERO (CRD42023403219); https://tinyurl.com/4tnzv49s.International registered report identifier (irrid)DERR1-10.2196/56403.

Project description:BackgroundBeing a family carer to a patient nearing the end of their life is a challenging and confronting experience. Studies show that caregiving can have negative consequences on the health of family carers including fatigue, sleep problems, depression, anxiety and burnout. One of the goals of palliative care is to provide psychosocial support to patients and families facing terminal illness. A systematic review of interventions for family carers of cancer and palliative care patients conducted at the start of this millennium demonstrated that there was a dearth of rigorous inquiry on this topic and consequently limited knowledge regarding the types of interventions likely to be effective in meeting the complex needs of family carers. We wanted to discern whether or not the evidence base to support family carers has improved. Furthermore, undertaking this review was acknowledged as one of the priorities for the International Palliative Care Family Carer Research Collaboration http://www.centreforpallcare.org.MethodsA systematic review was undertaken in order to identify developments in family carer support that have occurred over the last decade. The focus of the review was on interventions that targeted improvements in the psychosocial support of family carers of palliative care patients. Studies were graded to assess their quality.ResultsA total of fourteen studies met the inclusion criteria. The focus of interventions included psycho-education, psychosocial support, carer coping, symptom management, sleep promotion and family meetings. Five studies were randomised controlled trials, three of which met the criteria for the highest quality evidence. There were two prospective studies, five pre-test/post-test projects and two qualitative studies.ConclusionsThe systematic review identified a slight increase in the quality and quantity of psychosocial interventions conducted for family carers in the last decade. More rigorous intervention research is required in order to meet the supportive care needs of family carers of palliative care patients.

Project description:BackgroundMeeting psychosocial needs is a significant component of quality dementia care. To enable persons with dementia to live at home for as long as possible, a community healthcare service offering care where physical, social, psychological, cultural and spiritual needs are met, is recommended. A comprehensive allocation process is required to allocate individually tailored healthcare services. However, the allocation process for older home-dwelling persons with dementia, specifically for services to safeguard psychosocial needs, remains largely unexplored. Accordingly, this study aims to explore purchasers' deliberations on psychosocial needs during the process of allocating healthcare services to older home-dwelling persons with dementia.MethodsThe study had a descriptive design with a qualitative approach. The primary data source was focus group interviews with purchasers who assess and allocate healthcare services. The interview data were supplemented by a review of administrative decisions made by the purchasers. Data from the focus group interviews were analysed using a descriptive and interpretive approach. Content analysis of the administrative decisions was conducted.ResultsThe purchasers described the allocation process as challenging. The following four themes reflect the complexity of the allocation process: (i) an unfamiliar and unclear concept; (ii) a hierarchy of needs; (iii) an adjusting allocation process; (iv) a challenging documentation of administrative decisions.ConclusionsThe purchasers viewed a comprehensive allocation process as important. However, a web of different interplaying aspects prevented the purchasers from conducting a comprehensive need-led allocation process. Insufficient assessment or allocation threatens the adequate safeguarding of the psychosocial needs of persons with dementia. Having varied and sufficient services to allocate is of great importance, but is not sufficient. Psychosocial needs must be better incorporated as a significant element throughout the entire allocation process.
