Process evaluation of a multicomponent dyadic intervention study with exercise and support for people with dementia and their family caregivers

Effectiveness of a health education program for people with dementia and their family caregivers: An intervention by nurse practitioners

PURPOSE

This study assesses the effectiveness of a health education program on caregiving outcomes for people with dementia and their families.

METHODS

This quasi-experimental study involved 250 people with dementia and their family caregivers. Behavioral problems in people with dementia were assessed using the Chinese version of the Cohen-Mansfield Agitation Inventory-community form. Family caregiver outcomes were measured using the Agitation Management Self-Efficacy Scale, Caregiver Preparedness Scale, Competence Scale, and Community Resource Awareness and Utilization Assessment.

RESULTS

Following the intervention, the experimental group demonstrated significant improvements in terms of self-efficacy, preparedness, competence, and awareness and utilization of community resources among family caregivers. Additionally, the experimental group exhibited lower levels of behavioral problems among people with dementia.

CONCLUSIONS

This study helped improve caregiving outcomes for people with dementia and their family caregivers. Therefore, outpatient healthcare providers can utilize these findings to enhance care for this population.

Impact of telehealth on stroke survivor-caregiver dyad in at-home rehabilitation: A systematic review

AIM

To examine studies involving the impact of telerehabilitation (TLR), tele-training and tele-support on the dyad stroke survivor and caregiver in relation to psychological, physical, social and health dimensions.

DESIGN

A systematic review was conducted.

DATA SOURCES

The following electronic databases were consulted until September 2023: PsycInfo, CINAHL, Eric, Ovid, PubMed, Scopus, Cochrane Central and Web of Science.

REVIEW METHODS

It was conducted and reported following the checklists for Reviews of PRISMA 2020 Checklist. Critical evaluation of the quality of the studies included in the review was performed with the Joanna Briggs Institute Checklists.

DATA SYNTHESIS

A total of 2290 records were identified after removing duplicates, 501 articles were selected by title and abstract and only 21 met the inclusion criteria. It included 4 quasi-experimental studies, 7 RCTs, 1 cohort study and 9 qualitative studies. The total number of participants between caregivers and stroke survivors was 1697, including 858 stroke survivors and 839 caregivers recruited from 2002 to 2022. For a total of 884 participants who carried out TLR activities in the experimental groups,11 impact domains were identified: cognitive/functional, psychological, caregiver burden, social, general health and self-efficacy, family function, quality of life, healthcare utilization, preparedness, quality of care and relationship with technology.

CONCLUSIONS

The results support the application of telehealth in the discharge phase of hospitals and rehabilitation centres for stroke survivors and caregivers. TLR could be considered a substitute for traditional rehabilitation only if it is supported by a tele-learning programme for the caregiver and ongoing technical, computer and health support to satisfy the dyad's needs.

IMPACT

Designing a comprehensive telemedicine programme upon the return home of the dyad involved in the stroke improves the quality of life, functional, psychological, social, family status, self-efficacy, use of health systems and the dyad's preparation for managing the stroke.

Recruiting Persons With Dementia: A Systematic Review of Facilitators, Barriers, and Strategies

Study recruitment of persons with dementia is challenging. We aimed to assess facilitators, barriers, and strategies to identify and approach persons with dementia for recruitment to dementia care studies. We systematically searched MEDLINE/PubMed, CINAHL, Web of Science, and other sources (ORRCA [Online Resource for Research in Clinical triAls]; pertinent evidence syntheses; citation searching) and narratively summarised the results (PROSPERO CRD42022342600). Facilitators and barriers consisted of "characteristics of participants, researchers, clinical contact persons", "study characteristics", and "communication with participants". The highest number of participants were recruited by study information in electronic and print formats, as well as by networking and collaboration. Advertisements proved to be the most expensive way of recruitment. There is limited evidence on the impact of recruitment strategies to identify persons with dementia for recruitment to dementia care studies. Our analysis of facilitators and barriers may inform research teams in designing strategies to identify persons with dementia for recruitment purposes.

Implementation and dissemination of home- and community-based interventions for informal caregivers of people living with dementia: a systematic scoping review

BACKGROUND

Informal caregivers of people with dementia (PwD) living at home are often the primary source of care, and, in their role, they often experience loss of quality of life. Implementation science knowledge is needed to optimize the real-world outcomes of evidence-based interventions (EBIs) for informal caregivers. This scoping review aims to systematically synthesize the literature that reports implementation strategies employed to deliver home- and community-based EBIs for informal caregivers of PwD, implementation outcomes, and the barriers and facilitators to implementation of these EBIs.

METHODS

Embase, MEDLINE, Web of Science, and Cochrane Library were searched from inception to March 2021; included studies focused on "implementation science," "home- and community-based interventions," and "informal caregivers of people with dementia." Titles and abstracts were screened using ASReview (an innovative AI-based tool for evidence reviews), and data extraction was guided by the ERIC taxonomy, the Implementation Outcome Framework, and the Consolidated Framework for Implementation Science Research; each framework was used to examine a unique element of implementation.

RESULTS

Sixty-seven studies were included in the review. Multicomponent (26.9%) and eHealth (22.3%) interventions were most commonly reported, and 31.3% of included studies were guided by an implementation science framework. Training and education-related strategies and provision of interactive assistance were the implementation strategy clusters of the ERIC taxonomy where most implementation strategies were reported across the reviewed studies. Acceptability (82.1%), penetration (77.6%), and appropriateness (73.1%) were the most frequently reported implementation outcomes. Design quality and packaging (intervention component suitability) and cosmopolitanism (partnerships) constructs, and patient's needs and resources and available resources (infrastructure) constructs as per the CFIR framework, reflected the most frequently reported barriers and facilitators to implementation.

CONCLUSION

Included studies focused largely on intervention outcomes rather than implementation outcomes and lacked detailed insights on inner and outer setting determinants of implementation success or failure. Recent publications suggest implementation science in dementia research is developing but remains in nascent stages, requiring future studies to apply implementation science knowledge to obtain more contextually relevant findings and to structurally examine the mechanisms through which implementation partners can strategically leverage existing resources and regional networks to streamline local implementation. Mapping local evidence ecosystems will facilitate structured implementation planning and support implementation-focused theory building.

[Outreach dyadic support program for persons with dementia and relatives by dementia nursing experts: qualitative results from a pilot study in rural areas]

BACKGROUND AND OBJECTIVE

The quality of life of persons with dementia and their relatives crucially depends on whether they succeed in establishing a stable home care situation. In this study, an outreach dyadic support program for persons with dementia and relatives was carried out by dementia nursing experts (DNE) for the first time. The aim of the nurse-led dyadic support program focuses on the lifeworld benefits for dyads and the benefits towards coping with dementia and crisis management in their home environment. Does it turn out to be a suitable offer for dyads in rural areas? Could the program originally developed for therapists be carried out by DNE?

METHODS

Using an interview guideline, 12 episodic interviews were conducted with dyads and additionally two focus groups (n = 5 relatives and n = 2 dementia nursing experts). The interviews were recorded, transcribed verbatim and analyzed using content analysis.

RESULTS

The results of a qualitative evaluation with a multiperspective approach are presented. The participating dyadic benefit depends on several factors, e.g. dyadic relationship, stage of dementia, in different ways. The outreach approach is therefore important. The dyadic setting is mostly seen as helpful, a need for additional one-to-one meetings is desired. The program can be used by DNE, the shift can even be an advantage. It is questionable whether temporary support lasts over the entire course of the disease.

CONCLUSION

The results show that home care situations can be improved for dyads through the nurse-led program, they can even benefit by DNE. The possibility of one-to-one meetings and follow-up care should be given. The outreach approach is crucial for rural areas. The results point to the need for more outreach care for persons with dementia in order to reduce stress and strengthen identity and action resources.

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

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.

Strategies to engage people with dementia and their informal caregivers in dyadic intervention: A scoping review

Dyadic interventions simultaneously engage both people with dementia (PWD) and their informal caregivers (ICGs). This scoping review study identified the strategies for engaging dyads, described the perceptions of the dyads on these strategies, and reported the attrition rates of the dyadic interventions reported in the literature. Articles published up to July 2020, reporting a PWD-ICG-dyads intervention were searched in PubMed (Medline), PsycInfo, CINAHL, and the SSCI. Backwards citation chasing was conducted. A total of 37 studies were included. Seven engagement strategies were identified, which involved: ensuring a good-quality interventionist; offering take-home supporting materials; establishing peer support among the participants; tailoring the intervention content; conducting the intervention in a convenient location; conducting the intervention in a comfortable physical environment, and using a short and succinct programme. The dyads' subjective experiences of these strategies were reported. The attrition rates of the included studies were ranged 0% - 59.1%.

Intersectoral care management for older people with cognitive impairment during and after hospital stays [intersec-CM]: study protocol for a process evaluation within a randomised controlled trial

Background

In the healthcare system in Germany, different institutions and actors play specific roles in the discharge and transition of patients from hospitals into primary care (Sachverständigenrat zur Begutachtung der Entwicklung im Gesundheitswesen, Wettbewerb an der Schnittstelle zwischen ambulanter und stationärer Gesundheitsversorgung, 2012). However, there are shortcomings in these intersectoral transitions. Especially in older people with cognitive impairment (PCI), discharge management often lacks coordination and cooperation between healthcare providers. This frequently results in higher rates of unscheduled readmission. The project intersec-CM is a randomised controlled trial (RCT) that aims to explore up to what extent an intersectoral care management (ICM) can improve this transition. This ICM is delivered by nurses with special training in care management. The objective of this paper is to describe a mixed-methods process evaluation of the intersectoral care management intervention and the factors that facilitate and inhibit its implementation.

Methods

Different study designs for process evaluations from previous literature were collected and analysed according to the dimension implementation fidelity, satisfaction with the intervention, feasible transfer into routine care, optimum point of time, frequency and execution of the intervention, and context factors.

Results

The actor-network theory was chosen as the theoretic framework for the process evaluation. Based on this theory, a mixed-methods design was developed to combine and integrate qualitative and quantitative evaluation methods. The qualitative part includes semi-structured interviews using topic guides (phase 1) and later in-depth interviews with narrative portions (phase 3), which will be analysed by using the qualitative content analysis according to Kuckartz. The quantitative survey (phase 2) is conducted with standardised questionnaires.

Discussion

Challenges in data collection include the development of interview guidelines, which require different terminologies depending on every specific actor targeted in the intervention. Conducting the interviews, there is a risk of misunderstanding the older PCI by the interviewer and vice versa. However, the combination of qualitative and quantitative approaches as different techniques of process evaluation may help to capture, integrate and analyse data on different dimensions of the intervention.

Conclusions

The results of our process evaluation may serve as an implementation guideline for intersectoral care management in the German healthcare system. Furthermore, the approach to evaluate the process of a complex intervention in health care for older PCI may serve as a stimulus to broaden the evidence base also of other complex intervention studies to improve health care for this vulnerable group.

The study was ethically approved by the Ethics Committee of the Ernst-Moritz-Arndt University of Greifswald. The study has been registered at the U.S. National Library of Medicine.

Trial registration

ClinicalTrials.gov NCT03359408. Registered on 2 December 2017. The approximate date when recruitment to the process evaluation of the study will be completed is 31 May 2021.

Adherence to the Class-Based Component of a Tai Chi Exercise Intervention for People Living With Dementia and Their Informal Carers

The objective of this study was to understand the experiences of people living with dementia and their informal carers' taking part together (in dyads) in Tai Chi classes and the aspects influencing their adherence. Dyads' experiences of taking part in Tai Chi classes for 20 weeks within the TACIT Trial were explored through class observations (n = 22 dyads), home-interviews (n = 15 dyads), and feedback. Data were inductively coded following thematic analysis. Tai Chi classes designed for people with dementia and their informal carers were enjoyable and its movements, easy to learn. Facilitators of participants' adherence were the socializing component and their enjoyment of the classes, whereas unexpected health problems were the main barrier. Finding the optimal level of challenge in the class setting might be crucial for people with dementia to feel satisfied with their progression over sessions and enable their continued participation.

Caregiver dementia training in caregiver-patient dyads: Process evaluation of a randomized controlled study

OBJECTIVES

We performed a randomized controlled study to evaluate the effects of caregiver training on the well-being of both people with dementia and their caregivers. Before the effect analysis, we conducted a process evaluation to estimate internal and external validity. This was anticipated to augment our understanding of the outcomes.

METHODS

We focused on three questions. (a) Was the intervention performed as planned (internal validity)? (b) Can qualitative data be used to inform how the intervention evoked change? (c) Can the study outcomes be extrapolated to all caregivers living with people who have dementia (external validity)?

RESULTS

Responses from participants assigned to the intervention group suggested that the intervention was feasible, could be performed as planned, and that modelling and discussions between participants were important. However, participant recruitment to the entire study was ultimately laborious because participants had issues with the study design (risk of being assigned to the control group) and referrers lacked familiarity with the training (new type of intervention). Participants were also younger and better educated compared with the general population. Some dropouts in the follow-up period occurred due to the number of questionnaires, and this was more pronounced in the control group.

CONCLUSIONS

Although we achieved high internal validity, we lack certainty about the external validity. We not only experienced general difficulty in recruiting participants but also tended to recruit a biased sample that was relatively young and well educated. These factors combine to limit our ability to extrapolate the results to the general population.

Mixed-Methods Study on Caregiver Strain, Quality of Life, and Perceived Health

BACKGROUND

Caring for someone with dementia is associated with negative and positive experiences. There is little evidence based on large datasets.

OBJECTIVE

To present data around the experience of caring for someone with dementia, to identify support (emotional and practical) needs, and inform future service provision.

METHODS

A mixed-methods study embedded in the Promoting Activity, Independence and Stability in Early Dementia (PrAISED) Randomized Controlled Trial. We administered questionnaires on strain, quality of life (QoL), and perceived health to 301 caregivers and assessment of cognitive performance, depression, anxiety, and disability in activities of daily living to 301 participants with dementia. Data were analyzed through descriptive and modelling statistics. A subsample of 20 patient-caregiver dyads were qualitatively interviewed. Data around caregivers' experience of providing care were extrapolated and analyzed through inductive thematic analysis.

RESULTS

There were significant negative associations between caregiver strain and QoL (p < 0.01) and between caregiver age and QoL (p < 0.01), and significant positive associations between caregiver strain and disability (p < 0.01), cognitive impairment (p < 0.01), depression (p < 0.05), and anxiety of the person with dementia (p < 0.05). Older caregivers reported a lack of support, reinforced by their reluctance to seek help. All caregivers reported contradictory emotions associated with caring and accumulation of strain over time.

CONCLUSION

While there is recognition that it is essential to support caregivers, dedicated intervention programs, and support strategies to respond to the needs of older caregivers are still needed.

Factors affecting the delivery of complex rehabilitation interventions in research with neurologically impaired adults: a systematic review

BACKGROUND

Rehabilitation research does not always improve patient outcomes because of difficulties implementing complex health interventions. Identifying barriers and facilitators to implementation fidelity is critical. Not reporting implementation issues wastes research resources and risks erroneously attributing effectiveness when interventions are not implemented as planned, particularly progressing from single to multicentre trials. The Consolidated Framework for Implementation Research (CFIR) and Conceptual Framework for Implementation Fidelity (CFIF) facilitate identification of barriers and facilitators. This review sought to identify barriers and facilitators (determinants) affecting implementation in trials of complex rehabilitation interventions for adults with long-term neurological conditions (LTNC) and describe implementation issues.

METHODS

Implementation, complex health interventions and LTNC search terms were developed. Studies of all designs were eligible. Searches involved 11 databases, trial registries and citations. After screening titles and abstracts, two reviewers independently shortlisted studies. A third resolved discrepancies. One reviewer extracted data in two stages; 1) descriptive study data, 2) units of text describing determinants. Data were synthesised by (1) mapping determinants to CFIF and CFIR and (2) thematic analysis.

RESULTS

Forty-three studies, from 7434 records, reported implementation determinants; 41 reported both barriers and facilitators. Most implied determinants but five used implementation theory to inform recording. More barriers than facilitators were mapped onto CFIF and CFIR constructs. "Patient needs and resources", "readiness for implementation", "knowledge and beliefs about the intervention", "facilitation strategies", "participant responsiveness" were the most frequently mapped constructs. Constructs relating to the quality of intervention delivery, organisational/contextual aspects and trial-related issues were rarely tapped. Thematic analysis revealed the most frequently reported determinants related to adherence, intervention perceptions and attrition.

CONCLUSIONS

This review has described the barriers and facilitators identified in studies implementing complex interventions for people with LTNCs. Early adoption of implementation frameworks by trialists can simplify identification and reporting of factors affecting delivery of new complex rehabilitation interventions. It is vital to learn from previous experiences to prevent unnecessary repetitions of implementation failure at both trial and service provision levels. Reported facilitators can provide strategies for overcoming implementation issues. Reporting gaps may be due to the lack of standardised reporting methods, researcher ignorance and historical reporting requirements.

Reasons for nonparticipation in the Valuing Active Life in Dementia randomised controlled trial of a dyadic occupational therapy intervention: An interview study

Objectives:

There is currently little known about why people decline to participate in dyadic, psychosocial dementia research. This interview study aims to explore the reasons why people declined to participate in the Valuing Active Life in Dementia research trial.

Methods:

Ten family carers of people with dementia, who were part of a dyad that had declined to take part in the randomised controlled trial, participated in qualitative telephone interviews to explore their reasons for declining. Inductive thematic analysis was used to identify themes.

Findings:

Two themes with related sub-themes were identified: (1) Protectiveness – protecting the person with dementia, themselves as carers and their current lifestyle; (2) ‘It’s not for us’ – the time commitment, and the possible unsuitability of the intervention, was seen to outweigh the perceived benefit of taking part. People with dementia were not always involved in the decision-making process, with carers stating the decision not to participate was made in the usual way as all their decisions. No apparent differences between the spousal and the child carers were apparent in the small sample.

Conclusion:

Recruitment to randomised controlled trials can be considered difficult or unfair because some participants will miss out on the desired intervention. However, this study shows that concern about the time and inconvenience of being involved in the trial can put people off research participation. Identifying possible reasons for declining research participation contributes to the design of future trials and recruitment strategies, so that the potential benefit is considered relative to the time and effort involved. Offering research opportunities to people with dementia and their families at the right stage of the dementia trajectory for their needs, facilitating personalised recruitment strategies with finely tailored researcher communication skills should help maximise recruitment, reduce attrition and deliver a more successful trial.

People living with dementia and their family carers' adherence to home-based Tai Chi practice

Objectives

The aim of this study was to understand what influenced people living with dementia and their family carers’ adherence to the home-based component of a Tai Chi exercise intervention.

Method

Dyads, of people living with dementia and their family carers, who participated in the intervention arm of the Tai Chi for people living with dementia trial, were invited to join weekly Tai Chi classes for 20 weeks and practice at home. Semi-structured dyadic home interviews were conducted on average after 16 weeks of classes. The views of 15 dyads with a range of home practice adherence were sought in semi-structured interviews. The interviews were analysed using an inductive thematic approach.

Results

Most participants found time to practise Tai Chi at home and practised for 18 hours on average. Amongst the barriers to adherence were participants’ competing commitments and a booklet not sufficiently conveying the Tai Chi movements. Hence, a video or DVD was requested by participants. Facilitators of their adherence to the home-based component of the intervention were their enjoyment of the practice and the development of a habit, which was supported by their commitment to the study and their willingness to benefit from Tai Chi.

Conclusion

Enjoyment and perceived benefits had a great impact on participants living with dementia and their carers’ adherence to home-based Tai Chi practice. However, difficulties to perceive the Tai Chi movements through images might be hindering sustained participation. Hence, alternative aids such as videos and DVDs should be explored to facilitate adherence.

Effects of leisure-time physical activity interventions on frailty-related characteristics of frail older adults in long-term care: a systematic review

Background: The proportion of frailty in older adults is increasing in many countries. Demand for institutional long-term care followed by an increasing globally. Aims: The effects of leisure-time physical activity (LTPA) interventions on frail older adults in long-term care facilities (LTCFs) of randomized controlled trials. Design: A literature searches of the published articles indexed in CINAHL, MEDLINE, PsycINFO, ProQuest, and Google Scholar between 2000 and 2017 was conducted. Methods: The inclusion criteria were divided into four sections: (1) design: randomized controlled trials; (2) sample population: LTCF adults aged 60 years or over with frailty; (3) intervention: LTPA; and (4) body composition: physical, functional or neuropsychological tests as either the primary or the secondary outcomes. Results: Three main themes were identified (the particular monitor, intervention duration and outcome measurement dimensions). Impact statement and conclusions: LTPA interventions effectively improved the physical performance and body composition of frail older adults in LTCFs. Nevertheless, an optimal combination of intensity, duration and frequency is crucial.

Impacts of a multicomponent intervention programme on neuropsychiatric symptoms in people with dementia and psychological health of caregivers: A feasibility pilot study

OBJECTIVES

The objectives of this study are to explore the feasibility of a multicomponent intervention programme and to evaluate its impacts on behavioural and psychological symptoms of dementia (BPSD) and psychological health of caregivers.

METHODS

Fifty-six community-dwelling people with dementia (PWD) and knee osteoarthritis (OA) and their caregivers were recruited and randomized into the intervention group (IG) or comparison group (CG). Each participant in both groups received an individual physiotherapy session (personalized home exercises and care education) and underwent 8 weeks of a 1-hour-structured group exercise session weekly at a day care centre. They were instructed to follow the prescribed home exercise. The IG received a multicomponent programme, combining knee OA-specific therapeutic exercise with self-management support, while the CG attended the routine group exercise programme. The attendance rate and reasons for non-attendance were recorded for evaluating the feasibility. The Chinese versions of the Revised Scale for Caregiving Self-Efficacy (RSCSE) and the Neuropsychiatric Inventory Questionnaire (NPI-Q) were measured at the baseline and postintervention.

RESULTS

Fifty-four dyads completed the programme with high attendance rate (94.4%). Compared with the CG, caregivers in the IG significantly improved in three domains of RSCSE scores (P ≤ .005) and caregivers' distress (P = .004) after the intervention. However, no effects were observed in terms of BPSD severity in PWD. No adverse events or falls were reported.

CONCLUSION

This multicomponent programme is feasible and safe for dementia caregivers and older people with mild-to-moderate dementia and knee OA. The programme has beneficial effects on caregiving self-efficacy and distress of dementia caregivers.

AgeWell.de - study protocol of a pragmatic multi-center cluster-randomized controlled prevention trial against cognitive decline in older primary care patients

BACKGROUND

In the absence of treatment options, the WHO emphasizes the identification of effective prevention strategies as a key element to counteract the dementia epidemic. Regarding the complex nature of dementia, trials simultaneously targeting multiple risk factors should be particularly effective for prevention. So far, however, only few such multi-component trials have been launched, but yielding promising results. In Germany, comparable initiatives are lacking, and translation of these complex interventions into routine care was not yet done. Therefore, AgeWell.de will be conducted as the first multi-component prevention trial in Germany which is closely linked to the primary care setting.

METHODS

AgeWell.de will be designed as a multi-centric, cluster-randomized controlled multi-component prevention trial. Participants will be older community-dwelling general practitioner (GP) patients (60-77 years; n = 1,152) with increased dementia risk according to CAIDE (Cardiovascular Risk Factors, Aging, and Incidence of Dementia) Dementia Risk Score. Recruitment will take place at 5 study sites across Germany. GP practices will be randomized to either intervention A (advanced) or B (basic). GPs will be blinded to their respective group assignment, as will be the statistician conducting the randomization. The multi-component intervention (A) includes nutritional counseling, physical activity, cognitive training, optimization of medication, management of vascular risk factors, social activity, and, if necessary, further specific interventions targeting grief and depression. Intervention B includes general health advice on the intervention components and GP treatment as usual. We hypothesize that over the 2-year follow-up period the intervention group A will benefit significantly from the intervention program in terms of preserved cognitive function/delayed cognitive decline (primary outcome), and other relevant (secondary) outcomes (e.g. quality of life, social activities, depressive symptomatology, cost-effectiveness).

DISCUSSION

AgeWell.de will be the first multi-component trial targeting risk of cognitive decline in older adults in Germany. Compared to previous trials, AgeWell.de covers an even broader set of interventions suggested to be beneficial for the intended outcomes. The findings will add substantial knowledge on modifiable lifestyle factors to prevent or delay cognitive decline.

Acceptability of a Dyadic Tai Chi Intervention for Older People Living With Dementia and Their Informal Carers

Exercise is effective in preventing falls among older adults. However, few studies have included people living with dementia and their carers and explored their experiences. The aim of this study is to explore what affects the acceptability of exercise interventions to better meet the needs of people with dementia and their carers as a dyad. Observations, field notes containing participant's and instructor's feedback, and focus groups with 10 dyads involved in Tai Chi classes for 3 or 4 weeks in two sites in the South of England were thematically analyzed to understand their experiences. Findings suggest that dyads' determination to achieve the benefits of Tai Chi facilitated their adherence, whereas a member of the dyad's low sense of efficacy performing the movements during classes was a barrier. Simplifying class content and enhancing the clarity of instructions for home-based practice will be key to support the design of future exercise interventions.

Acceptability of psychosocial interventions for dementia caregivers: a systematic review

BACKGROUND

Most of patients with dementia are cared for by family members. Caring for people with dementia is challenging; approximately 30-55% of caregivers suffered from anxiety or depressive symptoms. A range of studies have shown that psychosocial interventions are effective and can improve caregivers' quality of life, reduce their care burden, and ease their anxiety or depressive symptoms. However, information on the acceptability of these interventions, despite being crucial, is under-reported.

METHODS

Systematic searches of databases were conducted for literature published on EMBASE, PubMed, The Cochrane Library, Web of Science, and PsycARTICLES until August 2017 and the searches were updated on June 2018. The selection criteria included primary studies with data about the acceptability of psychosocial interventions for informal caregivers and publications written in English. Two authors independently selected studies, extracted study characteristics and data, assessed the methodological quality of the included studies by using the Effective Public Health Practice Project (EPHPP) Quality Assessment Tool and Critical Appraisal Skills Programme (CASP) Qualitative Research Checklist, and conducted a narrative synthesis of quantitative and qualitative data.

RESULTS

A total of 10,610 abstracts were identified through systematic searches. Based on screening titles and abstracts, 207 papers were identified that met the criteria for full paper review, with 42 papers from 13 different countries meeting the inclusion criteria. We found high- and moderate-quality evidence showing psychosocial interventions were acceptable, with important benefits for caregivers. Facilitators of acceptability included caregivers' need for intervention, appropriate content and organization of the intervention, and knowledge and professionalism of the staff. Barriers to acceptability included participants' poor health status and low education levels, caregiving burden, change of intervention implementers, and poor system performance of interventions.

CONCLUSION

There is preliminary evidence to support the acceptability of psychosocial interventions for dementia caregivers. However, the available supporting evidence is limited, and there is currently no adequate information from these studies indicating that the acceptability has received enough attention from researchers. More well-designed studies assessing psychosocial interventions are needed to give specific statements about acceptability, and the measure of acceptability with psychosocial interventions should be more comprehensive.

The experiences of people with dementia and their carers participating in individual cognitive stimulation therapy

BACKGROUND

The carer-delivered individual cognitive stimulation therapy (iCST) was developed to improve cognition and quality of life of people with dementia. This study aims to explore people with dementia and family carers' concepts of mental stimulation and experiences of participating in the iCST intervention.

METHODS

A sub-sample of 23 dyads of people with dementia and their family carers who completed the iCST intervention took part in semi-structured in-depth interviews. Data were analysed using framework analysis.

RESULTS

Three main themes emerged, 'Concepts of mental stimulation', 'Experiencing changes in everyday life as a result of participating in iCST' and 'Carer adherence to the intervention' along with 10 sub-themes. The overall experience of participating in iCST was described as having opportunities to engage in enjoyable mentally stimulating activities, motivation to stay active and bringing people with dementia and their carers 'together'. Family carers mentioned that finding time to do the sessions and their relatives being reluctant to engage in the activities could hinder their participation in the intervention.

CONCLUSIONS

People with dementia and their family carers found iCST stimulating and enjoyable, but many had difficulty delivering all the sessions as planned. Family carers suggested that providing extra support by involving other people in delivering the intervention may help to improve adherence to the intervention. iCST may be a useful tool to encourage people with dementia and their carers to communicate.

The Effects of a Multicomponent Dyadic Intervention With Physical Exercise on the Cognitive Functioning of People With Dementia: A Randomized Controlled Trial

The objective was to evaluate the effects of a multicomponent dyadic intervention on the cognitive functioning of people with dementia living at home in a randomized controlled trial. People with dementia and their family caregivers (n = 111) were randomly assigned to 8 home-based sessions including physical exercise and support or a minimal intervention consisting of monthly written information bulletins and monthly phone calls. Memory, executive functioning (EF), and attention were assessed at baseline, and after 3 (postmeasurement) and 6 months (follow-up). Data were analyzed by using generalized estimating equations (GEE). A small, significant effect was found on attention. No effects were found on memory and EF. Finding only a small significant effect might be explained by the ineffectiveness of the intervention, but also by moderate treatment adherence or a lack of room for improvement because half of the people with dementia were already receiving care in a day care facility.

How do activating interventions fit the personal needs, characteristics and preferences of people with dementia living in the community and their informal caregivers?

Psychosocial interventions aim to mitigate the serious consequences of dementia for the daily life of people with dementia and their informal caregivers. To deliver a person-centred approach, it is crucial to take needs, characteristics and preferences of people with dementia and their informal caregivers into account. However, these factors are generally not systematically checked in order to determine which intervention will be most appropriate. Additionally, little is known about which intervention suits which needs, characteristics and preferences. Therefore, this study examined how three multiple-component, activating dyadic interventions fitted needs, characteristics, and preferences of both the people with dementia and their informal caregivers: the Pleasant Events Program, the Exercise and Support Intervention for People with Dementia and Their Caregivers, and Occupational Therapy. Semi-structured interviews were held with participants in either one of the interventions, 34 dyads and 19 professionals. The constant comparative method was used for the analysis. Five factors influenced the dyad’s ‘fit’: timing, need for activity, lifestyle, apart-or-together and meaning of (lost) activity. The factors ‘timing’ and a ‘need for activity’ were conditional for these activating interventions. Dyads in an early stage of dementia, who were aware of the effects on daily life, were open to a change in routine, and had a need to maintain activities profited from these interventions. Three distinctive factors were important for the fit of one of the three interventions in particular: ‘lifestyle’, ‘apart or together’ and ‘meaning of (lost) activity’. The Pleasant Events Programme and the Exercise and Support intervention properly addressed the need for activities that afforded daily pastimes or structure. The Exercise and Support Intervention addressed the need for physical activity and emphasized shared activity. Occupational Therapy properly addressed the need for self-sufficiency, maintaining activities and adjustment to physical limitations. These factors can contribute to a more person-centred application of the interventions.

Early Supported Discharge by Caregiver-Mediated Exercises and e-Health Support After Stroke: A Proof-of-Concept Trial

BACKGROUND AND PURPOSE

This proof-of-concept trial investigated the effects of an 8-week program of caregiver-mediated exercises commenced in hospital combined with tele-rehabilitation services on patient self-reported mobility and caregiver burden.

METHODS

Sixty-three hospitalized stroke patients (mean age 68.7, 64% female) were randomly allocated to an 8-week caregiver-mediated exercises program with e-health support or usual care. Primary outcome was the Stroke Impact Scale mobility domain. Secondary outcomes included length of stay, other Stroke Impact Scale domains, readmissions, motor impairment, strength, walking ability, balance, mobility, (extended) activities of daily living, psychosocial functioning, self-efficacy, quality of life, and fatigue. Additionally, caregiver's self-reported fatigue, symptoms of anxiety, self-efficacy, and strain were assessed. Assessments were completed at baseline and at 8 and 12 weeks.

RESULTS

Intention-to-treat analysis showed no between-group difference in Stroke Impact Scale mobility (P=0.6); however, carers reported less fatigue (4.6, confidence interval [CI] 95% 0.3-8.8; P=0.04) and higher self-efficacy (-3.3, CI 95% -5.7 to -0.9; P=0.01) at week 12. Per-protocol analysis, examining those who were discharged home with tele-rehabilitation demonstrated a trend toward improved mobility (-9.8, CI 95% -20.1 to 0.4; P=0.06), significantly improved extended activities of daily living scores at week 8 (-3.6, CI 95% -6.3 to -0.8; P=0.01) and week 12 (3.0, CI 95% -5.8 to -0.3; P=0.03), a 9-day shorter length of stay (P=0.046), and fewer readmissions over 12 months (P<0.05).

CONCLUSIONS

Caregiver-mediated exercises supported by tele-rehabilitation show promise to augment intensity of practice, resulting in improved patient-extended activities of daily living, reduced length of stay with fewer readmissions post stroke, and reduced levels of caregiver fatigue with increased feelings of self-efficacy. The current findings justify a larger definite phase III randomized controlled trial.

The effects of a multicomponent dyadic intervention on the mood, behavior, and physical health of people with dementia: a randomized controlled trial

PURPOSE

The effects of a multicomponent dyadic intervention on the mood, behavior, and physical health of people with dementia living in the community were evaluated in a randomized controlled trial. This multicomponent dyadic intervention is a translated and adapted version of an intervention that has been shown to be effective for people with dementia in the US.

PATIENTS AND METHODS

People with dementia living in the community and their family caregivers (N=111 caregiver-care recipient dyads) were randomly assigned to the intervention and comparison group. The intervention group received home-based physical exercise training, psycho-education, communication skills training, and pleasant activities training during 3 months directed at both the person with dementia and the caregiver. Mood, behavior, and physical health were measured at baseline, 3 months, and 6 months. The effects of the study were determined by using generalized estimating equations based on an intention-to-treat analysis.

RESULTS

Analyses showed no beneficial effects over time on any of the outcome measures.

CONCLUSION

This study showed no effects. The negative results in this study compared to the study that has been carried out in the US might be explained by the translation, adaptation, and shortening of the intervention used in the US, and a different social context. In addition, the results might be explained by the lack of room for improvement and by experiencing the intervention as too much of a burden. Furthermore, improving physical health might only be effective if the physical exercises are of moderate-to-high-intensity and are tailored in accordance with participants' preferences and needs. For future studies, because dyads often commented positively about the pleasure and support they received, it might also be valuable to measure quality of life outcomes such as relationship quality, pleasure, and self-esteem in dyadic focused interventions.

The effects of a multi-component dyadic intervention on the psychological distress of family caregivers providing care to people with dementia: a randomized controlled trial

BACKGROUND

Earlier research showed that multi-component dyadic interventions - including a combination of intervention strategies and addressing both the person with dementia and caregiver - have a beneficial impact on the mental and physical health of people with dementia and their family caregivers. A randomized controlled trial (RCT) of a multi-component dyadic intervention, which is a translated and adapted version of an intervention that has been shown to be effective in the US by Teri et al. (2003), was performed. The effects on caregivers' mood (primary outcome), burden, general health, and salivary cortisol levels (secondary outcomes) were studied.

METHODS

Community-dwelling people with dementia and their family caregivers (N = 111 dyads) were randomly assigned. The experimental group received eight home visits during three months, combining physical exercise and support (psycho-education, communication skills training, and planning of pleasant activities). Both the physical exercise and support component were directed at both the person with dementia and the caregiver. The comparison group received monthly information bulletins and phone calls. There were three measurements at baseline (prior to the intervention), at three months, and at six months into the intervention. Data were analyzed with Generalized Estimating Equations (GEE) based on an intention-to-treat analysis of all available data.

RESULTS

All analyses showed no benefits of the intervention over time on any of the outcomes.

CONCLUSION

The negative results might be explained by the translation and adaptation of the intervention that has been shown to be effective in the US: the intervention was shortened and did not include cognitive reframing. However, only the health effects on people with dementia and not on caregivers were studied in the US. Several other factors might also have played a role, which are important for future studies to take into account. These are: the usual health care in the country or region of implementation; the wishes and needs of participants for specific intervention components; the room for improvement regarding these components; the inclusion of positive outcome measures, such as pleasure, and the quality of the relationship.
