Intervention in informal caregivers who take care of older people after a stroke (InCARE): study protocol for a randomised trial

Using a Mixed-Method Approach to Explore the Factors Influencing the Family Resilience of Stroke Survivors in China

Background

Stroke is a critical public health issue in China that necessitates a closer examination of family resilience (defined here as the collective capacity of individuals, families and communities to effectively navigate challenges, recover from adverse events and foster positive adaptation). Amid rising stroke incidence, this study addresses the dearth of research on family resilience among stroke survivors in China, aiming to assess its level, identify influencing factors and establish coping strategies for family caregivers.

Methods

This mixed-methods research employed a sequential explanatory design. Questionnaires were distributed to 258 stroke survivors and their family members at outpatient follow-up visits. In the first stage (ie the quantitative research stage), the research tools for data collection included a general demographic sociological data questionnaire, the Family Resilience Assessment Scale (FRAS), the Self-Efficacy for Managing Chronic Disease 6-Item Scale, the Caregiver Burden Scale, the Family Functioning Scale and the Social Support Rating Scale. Quantitative data were analysed using IBM SPSS 26.0 software, utilising descriptive statistics for summarising sociodemographic characteristics and conducting analyses, such as independent-sample t-tests, one-way analysis of variance and Spearman correlation analysis. The second stage (ie the qualitative research stage) involved complementing and validating the data, developing a quantitative-qualitative interview framework and selecting participants for interviews. Colaizzi's seven-step analysis was applied to analyse interview data. In the third stage, the quantitative and qualitative research results were integrated, and a comprehensive analysis was performed to obtain an accurate conclusion.

Results

A total of 242 families responded to the questionnaire (response rate: 93.8%). In total, the mean age of stroke survivors was 61.86 ± 8.76 years old, and 69.8% were male. The quantitative results showed that the FRAS mean score was (185.33 ± 24.78), which was above the medium level. The multiple linear regression analysis confirmed that family function was the strongest influencing factor on family resilience (β = 0.948, p < 0.01). The qualitative analysis revealed four themes of family adaptation experience: loss of independence and certainty, facing threats and challenges, seeking family advantage resources and adopting coping strategies.

Conclusion

This hybrid study sheds light on the adaptation process of the families of stroke survivors, revealing family function as the primary influencer of resilience. Recognising that eliminating risk factors is challenging, our suggestion is for clinical practitioners to emphasise family strengths and implement resilience-oriented interventions. Focusing on enhancing coping abilities and fostering adaptation within families can aid in the rehabilitation process, promoting the well-being and growth of both the family unit and individual members, while alleviating caregiver burden.

Pilot testing of the strengthening caregiving activities program for Thai informal caregivers of dependent older people

This study sought to evaluate the feasibility and preliminary effect of the Strengthening Caregiving Activities Program on care partners' caregiver burden and activities of daily living (ADLs) ability. The program was used for the informal caregivers of dependent older people; 29 participants were recruited from a community center in Thailand. Caregiver burden and ADL changes were assessed for preliminary effects using the one-way repeated measure ANOVA at baseline, post-intervention, and follow-up. The six program sessions were implemented as intended, with 93.10% of participants reporting satisfaction with the program (M = 26.653; SD = 3.380). Caregiver burden statistically decreased after the intervention and follow-up (p < .05), but the care partners' ADLs did not. This program was feasible and showed promise for the reduction of caregiver burden. A randomized controlled trial should be conducted to test the effect of the Strengthening Caregiving Activities Program on large samples of caregivers.

The Influence of Informal Caregivers' Preparedness on Psychological Symptoms and Quality of Life Among Patients With Heart Failure And Insufficient Self-care

BACKGROUND

Most patients with heart failure find self-care difficult to perform and rely on family caregivers for support. Informal caregivers, however, often face insufficient psychological preparation and challenges in providing long-term care. Insufficient caregiver preparedness not only results in psychological burden for the informal caregivers but may also lead to a decline in caregiver contributions to patient self-care that affects patient outcomes.

OBJECTIVE

Our objective was to test (1) the association of baseline informal caregivers' preparedness with psychological symptoms (anxiety and depression) and quality of life 3 months after baseline among patients with insufficient self-care and (2) the mediating effects of caregivers' contributions to self-care of heart failure (CC-SCHF) on the relationship of caregivers' preparedness with patients' outcomes at 3 months.

METHODS

A longitudinal design was used to collect data between September 2020 and January 2022 in China. Data analyses were conducted using descriptive statistics, correlations, and linear mixed models. We used model 4 of the PROCESS program in SPSS with bootstrap testing to evaluate the mediating effect of CC-SCHF of informal caregivers' preparedness at baseline with psychological symptoms or quality of life among patients with HF 3 months later.

RESULTS

Caregiver preparedness was positively associated with CC-SCHF maintenance (r = 0.685, P < .01), CC-SCHF management (r = 0.403, P < .01), and CC-SCHF confidence (r = 0.600, P < .01). Good caregiver preparedness directly predicted lower psychological symptoms (anxiety and depression) and higher quality of life for patients with insufficient self-care. The associations of caregiver preparedness with short-term quality of life and depression of patients with HF with insufficient self-care were mediated by CC-SCHF management.

CONCLUSIONS

Enhancing the preparedness of informal caregivers may improve psychological symptoms and quality of life of heart failure patients with insufficient self-care.

Transcultural adaptation of the revised caregiving appraisal scale (RCAS) in the Spanish population

AIM

To develop a transcultural adaptation of the Revised Caregiving Appraisal Scale among Spanish caregivers of dependent older people and to test the psychometric properties of the scale.

DESIGN

Cross-sectional study.

METHODS

The Revised Caregiving Appraisal Scale was transculturally adapted to the Spanish population following the methodology of direct and back translation. The Spanish version of the Revised Caregiving Appraisal Scale was administered to a total of 182 family caregivers of older dependent people. The study began in January 2016 and ended in December of the same year. The construct validity was studied by means of the scree plot and parallel analysis. The exploratory factorial analysis was carried out, and the correlation between factors was studied. To verify the reliability of the process, Cronbach's alpha and homogeneity were calculated by the corrected total item correlation. The validity of the convergent criterion was studied by means of the Pearson correlation coefficient, using the Zarit Caregiver Load Interview and the Family Satisfaction Scale as the gold standard.

RESULTS

The construct validity revealed three factors: 'Subjective Burden' (15 items), 'Satisfaction' (7 items) and 'Competence' (3 items). The Cronbach alpha was .86 for 'Subjective Burden', .74 for 'Satisfaction' and .74 for 'Competence'. The corrected total item correlation was greater than .25. The validity of the convergent criterion of the 'Subjective Burden' and 'Competence' factors with the 'Zarit Caregiver's Load Interview' presented a very high statistically significant correlation, unlike 'Satisfaction' which presented a low positive correlation with the 'Family Satisfaction Scale'.

CONCLUSION

The Spanish version of the Revised Caregiving Appraisal Scale is a valid and reliable scale according to the tests performed on a random sample of family caregivers of older dependent people in Spain.

IMPACT

This scale will enable the simultaneous assessment of negative ('Subjective Burden' and 'Competence') and positive ('Satisfaction') perceptions among family caregivers of older dependent people.

Predictive model for the preparedness level of the family caregiver

Background

Many caregivers are insufficiently prepared, and little is known about measures that can be employed to enhance their preparedness.

Aim

The aim of this study was to explore the factors associated with caregiver preparedness and establish a predictive model including the relationship between preparedness, burden, resilience and anxiety.

Design

A cross‐sectional design was used.

Methods

The sample included 172 family caregivers who were selected from one private hospital and daytime nursing centres. Caregivers were recruited from 2018 to 2019; they completed assessments for caregiver preparedness, anxiety, resilience and burden. A multiple linear regression analysis was performed to identify the factors associated with preparedness.

Results

Preparedness was significantly associated with high levels of resilience and a low level of burden, while it was not associated with anxiety. Caregivers' gender, experience and cohabitation status were the main predictors. Resilience is an explanatory factor for caregiver preparedness in the predictive model.

Conclusion

The demographic variables related to preparedness can be used to guide efforts to meet the needs of vulnerable caregivers. A caregiver's preparedness depends on their level of burden and resilience. Nursing interventions focused on these aspects could make the caregiver's role easier and improve the quality of care provided.

What is already known about this topic?

Many caregivers are inadequately prepared for this role, and ensuring adequate preparedness is important for family caregivers.

Preparedness and factors predictive of this in Spanish family caregivers have not been well‐documented.

Resilience, burden and anxiety affect caregivers, but the degree to which they influence caregivers' preparation levels is unknown.

What is the contribution of this paper?

Specific factors influence the preparedness of family caregivers. Men and caregivers who do not cohabit in the same household with the care‐dependent person may present greater deficits in preparedness. Moreover, poor health and lack of experience in caring can result in inadequate caregiving performance.

Readiness, resilience and burden are significantly related, and the best predictor of family caregivers' preparedness is resilience.

Resilience leads to greater preparedness in caregivers, and better‐prepared caregivers experience a lighter burden.

What are the implications of this paper?

Knowing the factors associated with preparedness in advance will allow health‐care professionals to prevent deficits in vulnerable family caregivers.

Resilience is a decisive factor which prevents negative consequences such as low preparedness. A resilient coping style can diminish the burden and promote successful adaptation in caregivers.

e-Health as a tool to improve the quality of life of informal caregivers dealing with stroke patients: Systematic review with meta-analysis

OBJECTIVE

The objective of this review was to elucidate the evidence related to utilizing e-Health as a tool in improving the quality of life of informal caregivers of dependent patients due to cerebrovascular accident (CVA).

METHODS

This systematic review with meta-analysis includes 13 studies. For these studies, seven databases were searched between 2009 and 2019. A random-effects model was adopted for overall estimation and to explain the heterogeneity.

RESULTS

A random-effects model was adopted for overall estimation and to explain heterogeneity. The results did not demonstrate statistical significance (p<0.05) and low heterogeneity (I²  = 0).

CONCLUSIONS

There is a tendency toward improvement in psychological health, solving care-related problems, as well as better prevention of problems arising from the burden. Therefore, new studies with larger sample size and primarily to conduct them for more than 6 months for the accuracy.

CLINICAL RELEVANCE

This study reflects a trend toward improving psychological health, solving care-related problems, as well as improved the prevention of problems arising from the burden.

Development and validation a nursing care protocol with educational interventions for family caregivers of elderly people after stroke

OBJECTIVE

development and validation the content of a nursing care protocol with educational interventions for family caregivers of elderly people after stroke.

METHODS

a methodological study conducted in three stages: (1) protocol development through literature review; (2) pretest with multidisciplinary team, analyzed with literature articulation; (3) protocol validation by the Delphi Technique.

RESULTS

the protocol was structured in the following areas: Disease Guidelines; Emotional Support; Using the Health Care Network; Diet; Airways; Medications; Hygiene; Skin Care; Disposal; Dressing/Undressing; Positioning and Transfer; Fall Prevention. In the pretest, eight experts assessed protocol clarity and content. In validation, there were two rounds by the Delphi Technique. The validated protocol consisted of 12 domains, containing 42 items and 240 care guidelines.

CONCLUSION

the protocol qualifies the transition of care after hospital discharge assisting nurses in home care practice.

The effect of transition care interventions incorporating health coaching strategies for stroke survivors: A systematic review and meta-analysis

OBJECTIVE

To systematically analyse health coaching strategies in transition care and synthesise the effect of these strategies on health care outcomes for stroke survivors.

METHODS

A systematic search of nine databases in two languages was conducted. Meta-analysis was conducted when data were available.

RESULTS

Twenty-five randomised controlled trials met the inclusion criteria. The meta-analysis revealed that health coaching strategies in transition care interventions significantly improve quality of life (QoL) (p < 0.001), activities of daily living (ADL) (p = 0.002) and reduce depression (p = 0.001) for stroke survivors at 3 months. Further subgroup analysis demonstrated that transition care interventions with a greater number of health coaching strategies are associated with a larger effect size on QoL (SMD=1.15) and ADL (SMD=1.177) at 3 months, and a medium effect size (SMD=0.674) on depression reduction. However, the effects of health coaching strategies on readmission, mortality and falls in stroke survivors remain inconclusive.

CONCLUSIONS

This review provides evidence that incorporating health coaching strategies in transitional care improves health outcomes of stroke survivors.

PRACTICE IMPLICATION

More trials of health coaching interventions to improve transition care with a rigorous study design are much needed to address the lack of support for stroke survivors and their caregivers in this crucial care period.

The effect of family-centered empowerment program on the family caregiver burden and the activities of daily living of Iranian patients with stroke: a randomized controlled trial study

Dependence of stroke survivors regarding the ability to perform activities of daily living imposes a burden on family caregivers. The study evaluated the effect of the family-centered empowerment program on the ability of Iranian patients with stroke to perform activities of daily living, as well as on family caregiver burden. In this randomized controlled trial study, a total of 90 pairs of patients with stroke and their family caregivers was selected and randomly assigned to the intervention or control groups. Patients and their family caregivers participated in four family-centered empowerment program sessions over four consecutive days while the patient was hospitalized. The difference in the ability of patients with stroke in the intervention and control groups to perform activities of daily living was not significant 2 weeks after the intervention. However, the ability of patients with stroke in the intervention group to perform activities of daily living increased significantly 2 months after the intervention compared with the control group: 66 ± 35.95 and 51.31 ± 36.28, respectively (p = 0.047). Two weeks after the intervention, the family caregiver burden significantly decreased in the intervention group (29.55 ± 15.38) compared with the control group (38.77 ± 18.53 and p = 0.012). The burden in the intervention group also decreased 2 months after the intervention compared with the control group: 22.95 ± 15.68 and 36.11 ± 18.88, respectively (p < 0.001). Nurses can use the family-centered empowerment program to improve the quality of life of patients with stroke, and to reduce the burden of family caregivers.

Effects of personal characteristics, disease uncertainty and knowledge on family caregivers' preparedness of stroke survivors: a cross-sectional study

Family caregivers play an important role in the rehabilitation of stroke survivors. The aims of this study were to describe preparedness, uncertainty, and knowledge regarding stroke in family caregivers of people who have undergone strokes and to investigate factors influencing preparedness. A total of 306 caregivers completed the questionnaires, including the Caregiver Preparedness Scale, the Mishel Uncertainty in Illness Scale, and Knowledge of Stroke. The result showed that the mean score of the family caregivers' preparedness was 14.42, the mean score of disease uncertainty was 75.62, and the mean score of stroke knowledge was 10.41. Caregiver preparedness was negatively correlated with disease uncertainty and positively correlated with knowledge. Multivariate stepwise regression analysis showed that educational background, profession, caregiving experience and uncertainty degree of the family caregivers, gender, and age of stroke survivor could predict 45.90% of the total variation in preparedness. The findings suggest that demographic characteristics of stroke survivor and family caregiver, as well as caregivers' disease uncertainty, enable predict the level of caregiver preparedness. Medical professionals should pay attention to providing personalized and targeted approaches to maximize caregivers' preparedness.

Adaptation and Validation of the Capacity Scale for Informal Caregivers of Elderly Stroke Patients to be Used in Brazil

BACKGROUND AND PURPOSE

The Portuguese instrument for informal caregivers' skills providing care of aged people after a stroke (ECPICID-AVC) evaluates the capacities that informal caregivers must have for supporting aged stroke survivors. The purpose was to adapt and validate the ECPICID-AVC to be used in Brazil.

METHODS

A methodological study was conducted.

RESULTS

The terms with the lowest degree of comprehension were adapted. The factor analysis suggested the exclusion of three items and that the remaining be grouped into six domains. The factor loadings varied from 0.525 to 0.924. The internal intra-assessor consistency was satisfactory (ICC = 0.94, CI 95%). Total reliability was considered excellent (Cronbach's alpha = 0.914).

CONCLUSIONS

The ECPICID-AVC is considered appropriate for using in Brazil.

A nurse-led health coaching intervention for stroke survivors and their family caregivers in hospital to home transition care in Chongqing, China: a study protocol for a randomized controlled trial

BACKGROUND

Hospital to home transition care is a most stressful period for stroke survivors and their caregivers to learn self-management of stroke-related health conditions and to engage in rehabilitation. Health coaching has been identified as a strategy to enhance self-management of poststroke care at home. However, interventions in this field that are informed by a health coaching framework are scarce. This study will address a gap in research by testing the hypothesis that a nurse-led health coaching intervention can improve health outcomes for stroke survivors and their family caregivers in hospital to home transition care.

METHODS

This is a single-blind, two-arm parallel randomized controlled trial of a nurse-led health coaching program versus routine care situated in two tertiary hospitals in Chongqing, China. Stroke survivors and their primary family caregivers will be recruited together as "participant dyads", and the estimated sample size is 140 (70 in each group). The intervention includes a 12-week nurse-led health coaching program in hospital to home transition care commencing at discharge from the hospital. The primary outcome is changes in self-efficacy of stroke survivors at 12 weeks from the baseline. The secondary outcomes are changes in stroke survivors' and quality of life, functional ability, stroke-related knowledge, the number of adverse events, and unplanned hospital admissions, and caregivers' self-efficacy and caregiver-related burden at 12 weeks from the baseline. The outcomes will be measured at 12 weeks and 24 weeks from the baseline.

DISCUSSION

This study will examine the effect of nurse-led health coaching on hospital to home transition care for stroke survivors and their caregivers. It is anticipated that findings from this trial will provide research evidence to inform policy, and resource and practice development to improve hospital to home transition care for stroke survivors and their caregivers.

Interventions for Psychological Health of Stroke Caregivers: A Systematic Review

Background: The increasing number of stroke patients (SPs) requires informal caregivers to bear a high burden of responsibilities and heavy (di)stress. Moreover, these issues could lead to the development of serious psychological problems (e.g., depressive and/or anxious) that in turn could give rise to poor health-related quality of life outcomes. However, although the value of psychological interventions has been widely recognized for SPs, the scientific literature lacks an updated synthesis of interventions addressing the psychological health of their caregivers. Aim: The aim of this review is to summarize the interventions for the psychological health of stroke caregivers and provide a resume of literature-based evidence of their efficacy. Method: A literature review from 2005 to date was conducted in three online databases: PubMed, Scopus, and Google Scholar. Eligibility criteria for studies were (A) English language, (B) caregivers and patients aged 18 years or above, (C) SP's caregiver beneficiating of a specific intervention, and (D) outcome measures addressing depressive and/or anxiety symptomology, quality of life, well-being, or burden. Results: Across the selected 45 studies, substantial differences are observable in three main categories: (a) type of intervention (b) techniques, and (c) operators. Interventions' advantages and results are discussed. Overall, studies using psychological techniques, such as cognitive-behavioral therapy, coping skill-training, and problem-solving therapy, showed their usefulness and efficacy in reducing the caregivers' depressive and anxious symptoms, and burden. Interventions led by psychologists and tailored to meet caregivers' specific needs showed more positive outcomes. Conclusion: This review underlines the usefulness of psychological interventions aimed at reducing the psychological burden, such as anxious and depressive symptomatology, of SPs' informal caregivers. Hence, psychological interventions for caregivers should be integrated as part of the stroke rehabilitation process to improve informal caregivers' and patients' quality of life and well-being.

To manage a complex dependency: The experience of caregiving after a fall

AIM

To understand the experience of family members of an older relative who has had a fall which required medical attention.

BACKGROUND

There is abundant bibliography in caregiving, but little is known about the problems faced by caregivers and how family members cope when their older relative has a fall.

DESIGN

Qualitative study that used a symbolic interactionism perspective.

METHODS

Twenty-two people with older relatives, who had had a fall and contacted health services in Spain, participated in the study. Data were obtained via written accounts, focus groups, and semi-structured interviews between February 2014 - December 2015. Analysis was guided by grounded theory procedures.

RESULTS

With the fall, dependency becomes a complex issue for the family. To manage a complex dependency is the core issue that emerges from the data analysis. It depicts family efforts to assist their relative in gaining autonomy after a fall, in the best conditions they can provide. They do this with little guidance and support from healthcare professionals.

CONCLUSIONS

Guides and protocols for the care of a fragile older person, particularly after a fall, should not only include care but also support to caregivers. Health professionals and especially nurses need to be aware and respond to the family caregivers needs after a fall. To the fall prevention initiatives already in place, it must be added that those who support family members to cope with the care of an older person who has had a fall.

Training informal caregivers to care for older people after stroke: A quasi-experimental study

AIMS

This study aimed at evaluating whether training on practical skills involved in providing care reduces the burden experienced by informal caregivers and improves their general health condition.

BACKGROUND

A substantial number of informal caregivers lack skills to deliver poststroke assistance to older people after hospital discharge, which leads to burden situations as well as mental and physical health deterioration of the former.

DESIGN

A quasi-experimental design.

METHODS

This study involved 174 informal caregivers of older people who overcame a stroke. The control group (N = 89) received the usual type of care delivered in healthcare units. The experimental group (N = 85) adopted the InCARE programme for 1 week (T0), 1 month (T1) and 3 (T2) months and received telephone support by counselling caregivers on the subsequent 3rd, 6th, 8th and 10th weeks to hospital discharge. It aimed at facilitating the caregiver's adjustment to the demands of a poststroke stage and at increasing knowledge and practical skills to support the decision-making. Data collection occurred between February-December 2014 at the Community Home Care Services in northern Portugal.

RESULTS

The experimental group obtained significantly better results regarding practical skills as well as lower burden levels and a better general mental health condition when compared with the control group 1 (T1) and 3 (T2) months after intervention.

CONCLUSION

Findings suggest that our programme improved practical skills, helped reduce burden levels with better scores and improvement regarding general mental health condition of informal caregivers.

Quality of life, anxiety, depression and burden among stroke caregivers: A longitudinal, observational multicentre study

AIM

To longitudinally describe stroke caregivers' quality of life, anxiety, depression and burden and to identify predictors of stroke caregivers' quality of life, anxiety, depression and burden.

BACKGROUND

Caregivers have a key role in stroke survivor care and the first year of caregiving is the most challenging. To give tailored interventions, it is important to capture changes and identify predictors of caregiver quality of life, anxiety, depression and burden during the first year.

DESIGN

A 12-month longitudinal study. Data were collected between June 2013-May 2016.

METHODS

Changes in stroke caregiver quality of life, anxiety and depression and burden and their predictors were identified using linear mixed-effects models.

RESULTS

The caregivers (N = 244) were 53 years old and mostly female. Caregiver quality of life did not change significantly over the 12 months, anxiety and depression decreased up to 9 months and caregiver burden decreased from baseline to 3 months, then increased up to 9 months. Higher caregiver quality of life was predicted by caregiver younger age, higher education, living with a stroke survivor, survivor older age and higher physical functioning; higher anxiety and depression were predicted by older caregiver age and younger survivor age; higher burden was predicted by caregiver male gender, the caregiver not living with survivor and survivor lower physical functioning.

CONCLUSION

The first 9 months of caregiving are particularly problematic for caregivers. The trajectories of the above variables and their predictors may be useful for policy makers, clinicians, investigators and educators to give better care to stroke caregivers and their survivors.

Nursing home care educational intervention for family caregivers of older adults post stroke (SHARE): study protocol for a randomised trial

BACKGROUND

Family caregivers of aged stroke survivors face challenging difficulties such as the lack of support and the knowledge and skills to practice home care. These aspects negatively influence the caregivers' burden and quality of life, the use of health services, and hospital readmissions of the stroke survivor. The aim of this research is to describe an educational intervention focused on family caregivers of stroke survivors for the development of home care in the south of Brazil.

METHODS

A randomized clinical trial with 48 family caregivers of stroke survivors will be recruited and divided into two groups: 24 in the intervention group and 24 in the control group. The intervention will consist of the systematic follow-up by nurses who will perform three home visits over a period of 1 month. The control group will not receive the visits and will have the usual care guidelines of the health services. Primary outcomes: burden and quality of life of the caregiver.

SECONDARY OUTCOMES

functional capacity and readmissions of the stroke survivors; the use of health services of the stroke survivors and their family caregivers. Outcomes will be measured 2 months after discharge. The project was approved in April 2016.

DISCUSSION

This research offers information for conducting educational intervention with family caregivers of stroke survivors, presenting knowledge so that nurses can structure and plan the actions aimed at the education of the family caregiver. It is expected that the educational intervention will contribute to reducing caregiver burden and improving their quality of life, as well as avoiding readmissions and inadequate use of health services by stroke survivors.

CONTENT VALIDATION OF NURSING OUTCOMES IN RELATION TO FAMILY CAREGIVERS: CONTENT VALIDATION BY BRAZILIAN AND COLOMBIAN EXPERTS

ABSTRACT Objective: this study's aim was to estimate the content validity of nursing outcomes in relation to family caregivers. Method: eleven Brazilian and Colombian experts participated in the study. None of the 61 indicators of the four nursing outcomes were considered irrelevant; 42 (68.9%) were considered primary and 19 (31.1%) were considered secondary. Results: the indicators with higher validity scores were: family share care responsibilities for Caregiver well-being (CVI=0.85); disruption of family dynamics to Caregiver lifestyle disruption (CVI=0.85); perceived spiritual well-being and anger for Caregiver emotional health (CVI=0.79) and perceived general health to Caregiver physical health (CVI=0.79). Conclusion: the nursing outcomes studied had adequate content validity. It is recommended that content validation followed by clinical and construct validation of the nursing-sensitive outcomes be given in different cultures and care settings.

Caregiver-mediated exercises for improving outcomes after stroke

BACKGROUND

Stroke is a major cause of long-term disability in adults. Several systematic reviews have shown that a higher intensity of training can lead to better functional outcomes after stroke. Currently, the resources in inpatient settings are not always sufficient and innovative methods are necessary to meet these recommendations without increasing healthcare costs. A resource efficient method to augment intensity of training could be to involve caregivers in exercise training. A caregiver-mediated exercise programme has the potential to improve outcomes in terms of body function, activities, and participation in people with stroke. In addition, caregivers are more actively involved in the rehabilitation process, which may increase feelings of empowerment with reduced levels of caregiver burden and could facilitate the transition from rehabilitation facility (in hospital, rehabilitation centre, or nursing home) to home setting. As a consequence, length of stay might be reduced and early supported discharge could be enhanced.

OBJECTIVES

To determine if caregiver-mediated exercises (CME) improve functional ability and health-related quality of life in people with stroke, and to determine the effect on caregiver burden.

SEARCH METHODS

We searched the Cochrane Stroke Group Trials Register (October 2015), CENTRAL (the Cochrane Library, 2015, Issue 10), MEDLINE (1946 to October 2015), Embase (1980 to December 2015), CINAHL (1982 to December 2015), SPORTDiscus (1985 to December 2015), three additional databases (two in October 2015, one in December 2015), and six additional trial registers (October 2015). We also screened reference lists of relevant publications and contacted authors in the field.

SELECTION CRITERIA

Randomised controlled trials comparing CME to usual care, no intervention, or another intervention as long as it was not caregiver-mediated, aimed at improving motor function in people who have had a stroke.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected trials. One review author extracted data, and assessed quality and risk of bias, and a second review author cross-checked these data and assessed quality. We determined the quality of the evidence using GRADE. The small number of included studies limited the pre-planned analyses.

MAIN RESULTS

We included nine trials about CME, of which six trials with 333 patient-caregiver couples were included in the meta-analysis. The small number of studies, participants, and a variety of outcome measures rendered summarising and combining of data in meta-analysis difficult. In addition, in some studies, CME was the only intervention (CME-core), whereas in other studies, caregivers provided another, existing intervention, such as constraint-induced movement therapy. For trials in the latter category, it was difficult to separate the effects of CME from the effects of the other intervention.We found no significant effect of CME on basic ADL when pooling all trial data post intervention (4 studies; standardised mean difference (SMD) 0.21, 95% confidence interval (CI) -0.02 to 0.44; P = 0.07; moderate-quality evidence) or at follow-up (2 studies; mean difference (MD) 2.69, 95% CI -8.18 to 13.55; P = 0.63; low-quality evidence). In addition, we found no significant effects of CME on extended ADL at post intervention (two studies; SMD 0.07, 95% CI -0.21 to 0.35; P = 0.64; low-quality evidence) or at follow-up (2 studies; SMD 0.11, 95% CI -0.17 to 0.39; P = 0.45; low-quality evidence).Caregiver burden did not increase at the end of the intervention (2 studies; SMD -0.04, 95% CI -0.45 to 0.37; P = 0.86; moderate-quality evidence) or at follow-up (1 study; MD 0.60, 95% CI -0.71 to 1.91; P = 0.37; very low-quality evidence).At the end of intervention, CME significantly improved the secondary outcomes of standing balance (3 studies; SMD 0.53, 95% CI 0.19 to 0.87; P = 0.002; low-quality evidence) and quality of life (1 study; physical functioning: MD 12.40, 95% CI 1.67 to 23.13; P = 0.02; mobility: MD 18.20, 95% CI 7.54 to 28.86; P = 0.0008; general recovery: MD 15.10, 95% CI 8.44 to 21.76; P < 0.00001; very low-quality evidence). At follow-up, we found a significant effect in favour of CME for Six-Minute Walking Test distance (1 study; MD 109.50 m, 95% CI 17.12 to 201.88; P = 0.02; very low-quality evidence). We also found a significant effect in favour of the control group at the end of intervention, regarding performance time on the Wolf Motor Function test (2 studies; MD -1.72, 95% CI -2.23 to -1.21; P < 0.00001; low-quality evidence). We found no significant effects for the other secondary outcomes (i.e.

PATIENT

motor impairment, upper limb function, mood, fatigue, length of stay and adverse events; caregiver: mood and quality of life).In contrast to the primary analysis, sensitivity analysis of CME-core showed a significant effect of CME on basic ADL post intervention (2 studies; MD 9.45, 95% CI 2.11 to 16.78; P = 0.01; moderate-quality evidence).The methodological quality of the included trials and variability in interventions (e.g. content, timing, and duration), affected the validity and generalisability of these observed results.

AUTHORS' CONCLUSIONS

There is very low- to moderate-quality evidence that CME may be a valuable intervention to augment the pallet of therapeutic options for stroke rehabilitation. Included studies were small, heterogeneous, and some trials had an unclear or high risk of bias. Future high-quality research should determine whether CME interventions are (cost-)effective.
