RESUMO

BACKGROUND: Health care teams along the stroke recovery continuum have a responsibility to support care transitions and return to the community. Ideally, individualized care will consider patient and family preferences, best available evidence, and health care professional input. Person-centered care can improve patient-practitioner interactions through shared decision-making in which health professionals and institutions are sensitive to those for whom they provide care. However, it is unclear how the concepts of person-centered care have been described in reports of stroke transitional care interventions. METHODS: A secondary analysis of a systematic review and meta-analysis was undertaken. We retrieved all included articles (n=17) and evaluated the extent to which each intervention explicitly addressed 7 domains of person-centered care: alignment of care with patients' values, preferences, and needs; coordination of care; information and education; physical comfort; emotional support; family and friend involvement; and smooth transition and continuity of care. RESULTS: Most of the articles included some aspects of person-centeredness; we found that certain domains were not addressed in the descriptions of transitional care interventions, and no articles mentioned all 7 domains of person-centered care. We identified 3 implications for practice and research: (1) delineating person-centered care components when reporting interventions, (2) elucidating social and cultural factors relevant to the study sample and intervention, and (3) clearly describing the role of family and nonmedical support in the intervention. CONCLUSIONS: There is still room for greater consistency in the reporting of person-centeredness in stroke transitions of care interventions, despite a long-standing definition and conceptualization of person-centered care in academic and clinically focused literature.

RESUMO

This study aims to (1) characterize healthcare professionals' (HCPs') experiences related to the prevention and management of pressure injuries (PIs) and (2) explore the educational needs of individuals with a past or current history of PIs and their caregivers from the perspective of HCPs. This is a qualitative descriptive study. HCPs (n = 18) were interviewed using a semi-structured interview guide. Interviews were audio-recorded, transcribed verbatim and coded using NVivo. Three overarching themes encompassing various dimensions were identified: (1) Facilitators related to PI prevention and management, (2) Challenges related to PI prevention and management and (3) Recommendations for improving patient and caregiver PI education. HCPs identified a greater number of challenges than facilitators related to PI care. This study emphasizes the importance of a patient-centred and interprofessional approach to patient education for PI prevention and management. Meaningful interventions focused on the patient may improve health literacy and empower patients and caregivers in PI care. Investing in preventive measures and raising awareness are crucial to reducing PI incidence. The findings have implications for HCPs and researchers seeking to enhance patient care and promote effective PI prevention strategies.

RESUMO

BACKGROUND: This study aimed to test, in real-world clinical practice, the effectiveness of a Transitional Care Stroke Intervention (TCSI) compared to usual care on health outcomes, self-management, patient experience, and health and social service use costs in older adults (≥ 55 years) with stroke and multimorbidity (≥ 2 chronic conditions). METHODS: This pragmatic randomized controlled trial (RCT) included older adults discharged from hospital to community with stroke and multimorbidity using outpatient stroke rehabilitation services in two communities in Ontario, Canada. Participants were randomized 1:1 to usual care (control group) or usual care plus the 6-month TCSI (intervention group). The TCSI was delivered virtually by an interprofessional (IP) team, and included care coordination/system navigation support, phone/video visits, monthly IP team conferences, and an online resource to support system navigation. The primary outcome was risk of hospital readmission (all cause) after six-months. Secondary outcomes included physical and mental functioning, stroke self-management, patient experience, and health and social service use costs. The intention-to-treat principle was used to conduct the primary and secondary analyses. RESULTS: Ninety participants were enrolled (44 intervention, 46 control); 11 (12%) participants were lost to follow-up, leaving 79 (39 intervention, 40 control). No significant between-group differences were seen for baseline to six-month risk of hospital readmission. Differences favouring the intervention group were seen in the following secondary outcomes: physical functioning (SF-12 PCS mean difference: 5.10; 95% CI: 1.58-8.62, p = 0.005), stroke self-management (Southampton Stroke Self-Management Questionnaire mean difference: 6.00; 95% CI: 0.51-11.50, p = 0.03), and patient experience (Person-Centred Coordinated Care Experiences Questionnaire mean difference: 2.64, 95% CI: 0.81, 4.47, p = 0.005). No between-group differences were found in total healthcare costs or other secondary outcomes. CONCLUSIONS: Although participation in the TCSI did not impact hospital readmissions, there were improvements in physical functioning, stroke self-management and patient experience in older adults with stroke and multimorbidity without increasing total healthcare costs. Challenges associated with the COVID-19 pandemic, including the shift from in-person to virtual delivery, and re-deployment of interventionists could have influenced the results. A larger pragmatic RCT is needed to determine intervention effectiveness in diverse geographic settings and ethno-cultural populations and examine intervention scalability.

RESUMO

OBJECTIVES: Family members are often involved in the provision of care to a relative at some point in their life. Their role becomes inherently complex when their care recipient is interested in seeking medical assistance in dying (MAID). As assisted death for "grievous and irremediable conditions" was legalized in Canada in 2016, the perspectives of family caregivers have received little attention. To best support caregivers to individuals seeking assisted dying, healthcare practitioners must first understand the perspectives of family caregivers in this context. The objective of this qualitative study was to explore the experiences and support needs of family caregivers who are or who have provided care to individuals who are seeking or have sought MAID. METHODS: This study employed a qualitative descriptive design. Family caregivers supporting individuals living with grievous and irremediable conditions were recruited through social media outlets and support organizations. Data were collected through semi-structured telephone interviews and online surveys. Data were transcribed and analyzed using thematic analysis. RESULTS: The study included 11 participants, comprising spouses, parents, and adult children. The research identified three prevalent themes: the caregiver experience including roles and responsibilities and the impact of their role; the MAID experience including the process and their thoughts and feelings about MAID; and caregiver insight into supports and services viewed as valuable or needed for the MAID process. SIGNIFICANCE OF RESULTS: Study findings may assist in the provision and development of best practice resources and guidelines to support healthcare professionals involved in the delivery of MAID. Specifically, caregivers need to be supported in the context of their caregiving responsibilities to minimize the impact on their own lives and optimize their MAID experience.

RESUMO

BACKGROUND: Siblings often share in the care of parents with dementia, but little is known about how care is shared. Research suggests that in comparison with their brothers, sisters provide the majority of care to a parent with dementia and this can contribute to the sisters experiencing poorer health outcomes. There is limited knowledge about how to guide siblings who share in the care of a parent with dementia. AIM: Our qualitative descriptive study sought to explore the experiences of adult daughters sharing care responsibilities with their siblings. The study protocol was approved by institutional (University of Toronto and Baycrest Health Sciences) research ethics boards. MATERIALS & METHODS: Thirty-four daughters participated in an online qualitative survey. Data were analysed using Braun and Clarke's (Qualitative Research in Psychology, 3, 2006, 77) 6-step process. RESULTS: In an overarching theme, daughters expected shared caregiving with their siblings. They conceptualised this to be a practice of being equitable in dividing care responsibilities and fulfilling a supportive role for a parent with dementia; however, this expectation was not met by most daughters. Two subthemes were identified: (a) factors facilitating/constraining shared caregiving and (b) consequences of sharing care. The findings highlight the importance of understanding shared caregiving among siblings when caring for a parent with dementia. DISCUSSION: Results from this study suggest that although shared caregiving is often the goal, factors such as gender roles, geographical proximity, caregiver expertise/skill set and work schedules affect caregivers' abilities to share caregiving. These factors affected whether daughters viewed the caregiving situation as being shared equitably or inequitably, and this led to feelings of acceptance or resentment of their sibling's contribution to the care of their parent. CONCLUSIONS: Healthcare providers can utilise these findings to better support adult-child caregivers negotiating care with their siblings.

RESUMO

BACKGROUND: Dementia is a major public health concern associated with significant caregiver demands and there are technologies available to assist with caregiving. However, there is a paucity of information on caregiver needs and preferences for these technologies, particularly from a sex and gender perspective. To address this gap in research, the objectives of this study are to examine (1) the knowledge of technology, (2) perceived usefulness of technology, (3) feature preferences when installing and using technology and (4) sex and gender influences on technology needs and preferences among family caregivers of persons with dementia (PWD) across North America. METHODS: A secondary analysis was conducted on an existing cross-sectional survey with family caregivers of PWDs. Respondents were recruited through the Alzheimer Society of Canada, the Victorian Order of Nurses and Adult Day Programs and other Canadian health care provision institutes. Descriptive statistics, bivariate and multivariate analyses were used to describe the study sample, uncover differences between male and female caregivers and examine sex and gender influences on caregivers' technology needs and preferences. RESULTS: A total of 381 eligible responses were received over a nine month data collection period. The majority of respondents did not know much about and never used any technologies to assist with caregiving. "Being easy to install", "easy to learn how to use" and "cost" were identified as the most important features when purchasing and setting up technology, while "reliability" was identified as the most important feature when using technology. Most respondents were willing to pay up to $500 to acquire individual technologies. Controlling for other socio-demographic variables, female respondents were more likely to have some or more knowledge about technology for caregiving while male respondents were more willing to pay higher amounts for these technologies compared to their female counterparts. CONCLUSIONS: As one of the first studies of its kind, our findings represent a step towards the incorporation of sex and gender considerations such as cost and reliability in technology design and promotion for caregivers. Future efforts are warranted to establish an in-depth understanding of sex and gender influences in relation to other social and environmental factors.

RESUMO

BACKGROUND: Canada's aging population is increasing, along with the number of caregivers providing support to seniors. Caregiving is a taxing responsibility that often results in loneliness and distress. Creating awareness of available supports for caregivers is essential for their health and to provide the best support to the care recipients. This study aims to better understand and improve the caregiving experience for caregivers from diverse ethnic communities and the LGBTQI2S+ communities. The goal is to improve the well-being and resilience of caregivers and optimize outcomes for care recipients by delivering educational workshops that resemble the design of existing workshops currently offered by the participating social service agency. Content will be adapted based on identified participant learning needs. These workshops will be offered to the English-speaking community, diverse newcomer ethnic groups and the LGBTQI2S+ community. METHODS: This mixed-methods, longitudinal study includes two streams of caregivers; Stream One consists of English-speaking caregivers and care recipients while Stream Two includes individuals from the Afghan, Iranian, Somali-, Tamil- and Spanish-speaking populations and those belonging to LGBTQI2S+ communities. Each stream has two phases; Phase One includes needs assessments using focus groups and semi-structured interviews with caregivers and care recipients while Phase Two includes a pre-test post-test evaluation of educational workshops. The anticipated sample size for Phase One is 30 caregivers from the English-speaking community, 150 from the five linguistic/cultural communities combined and 30 from the LGBTQI2S+ group. For Phase Two, we plan to recruit 250 caregivers from the English-speaking community, 250 from the five linguistic/cultural communities, and 50 from the LGBTQI2S+ group. DISCUSSION: To provide caregivers with optimal support, we must acknowledge the caregivers and care recipients from diverse communities. Currently, at least two focus groups have been conducted with caregivers from each of the seven targeted groups and workshops have begun for all communities. Recruitment has been a challenge for all groups, but our team continues to conduct outreach with caregivers and will use our learning to inform the delivery of educational caregiver workshops.

RESUMO

Background and Purpose- Family caregivers play a central role in the recovery of people with stroke. They need support to optimize the care they provide and their own health and well-being. Despite support from the literature and best practice recommendations, healthcare systems are not formally adopting caregiver programs. This study aimed to describe system-level facilitators and barriers to caregiver support program implementation in a regional stroke system. Methods- Using a qualitative descriptive study design, focus groups were conducted with regional rehabilitation specialists, education coordinators, community and long-term care specialists, and regional/district program directors. Semi-structured interviews were conducted with regional medical directors, health professionals providing stroke care in acute care, rehabilitation and community settings, regional health executives, and primary care leaders. Data were analyzed using inductive thematic analysis. Results- Four focus groups (n=43) and 29 interviews were conducted. We identified 4 themes related to caregiver program implementation: (1) establishing the need for caregiver education and support in an integrated healthcare system; (2) incorporating caregiver programs into the system of care across the care continuum; (3) uncertainty regarding ownership and responsibility for implementation; and (4) addressing regional variations related to access, availability, and culture. Conclusions- This study provides a comprehensive understanding of organization and system-level considerations for implementing caregiver programs in a regional stroke system. Program implementation requires evidence to establish the need for caregiver programs, practical strategies, and establishing ownership to incorporate programs into existing healthcare systems, and consideration of regional variations across healthcare systems. Ultimately, adopting programs to support caregivers will improve recovery in people with stroke and caregiver well-being.

RESUMO

BACKGROUND: Few resources are available to support caregivers of patients who have survived critical illness; consequently, the caregivers' own health may suffer. We studied caregiver and patient characteristics to determine which characteristics were associated with caregivers' health outcomes during the first year after patient discharge from an intensive care unit (ICU). METHODS: We prospectively enrolled 280 caregivers of patients who had received 7 or more days of mechanical ventilation in an ICU. Using hospital data and self-administered questionnaires, we collected information on caregiver and patient characteristics, including caregiver depressive symptoms, psychological well-being, health-related quality of life, sense of control over life, and effect of providing care on other activities. Assessments occurred 7 days and 3, 6, and 12 months after ICU discharge. RESULTS: The caregivers' mean age was 53 years, 70% were women, and 61% were caring for a spouse. A large percentage of caregivers (67% initially and 43% at 1 year) reported high levels of depressive symptoms. Depressive symptoms decreased at least partially with time in 84% of the caregivers but did not in 16%. Variables that were significantly associated with worse mental health outcomes in caregivers were younger age, greater effect of patient care on other activities, less social support, less sense of control over life, and less personal growth. No patient variables were consistently associated with caregiver outcomes over time. CONCLUSIONS: In this study, most caregivers of critically ill patients reported high levels of depressive symptoms, which commonly persisted up to 1 year and did not decrease in some caregivers.

RESUMO

BACKGROUND: Following spinal cord injury (SCI), family members are often called upon to undertake the caregiving role. This change in the nature of the relationship between the individuals with SCI and their families can lead to emotional, psychological, and relationship challenges. There is limited research on how individuals with SCI and their family caregivers adapt to their new lives post-injury, or on which dyadic coping strategies are used to maintain relationships. Thus, the objectives of this study were to obtain an in-depth understanding of 1) the experiences and challenges within a caregiving relationship post-SCI among spouses, as well as parents and adult children; and 2) the coping strategies used by caregivers and care recipients to maintain/rebuild their relationships. METHODS: A qualitative descriptive approach with an exploratory design was used. Semi-structured face-to-face and telephone interviews were conducted. Thematic analysis was used to identify key themes arising from individuals with SCI's (n = 19) and their family caregivers' (n = 15) experiences. RESULTS: Individuals with SCI and family caregivers spoke in-depth and openly about their experiences and challenges post-injury, with two emerging themes (including subsequent sub-themes). The first theme of deterioration of relationship, which reflects the challenges experienced/factors that contributed to disintegration in a relationship post-injury, included: protective behaviours, asymmetrical dependency, loss of sex and intimacy, and difficulty adapting. The second theme of re-building/maintaining the relationship, which reflects the strategies used by dyads to adjust to the changes within the relationship brought upon by the injury, included: interdependence, shifting commonalities, adding creativity into routine, and creating a new normal. CONCLUSIONS: These findings should alert healthcare professionals and peer support groups as to the need for possible education and training (e.g., coping strategies, communication skills training) as well as counseling prior to discharge to assist individuals with SCI and family caregivers with adaptation to a new life post-injury.

RESUMO

OBJECTIVES: The primary objectives are to assess the most common type of caregiver strategy (remedial vs compensatory) reported for supporting their child's home participation after critical illness and identify themes in compensatory strategies described, with a secondary objective to describe themes in strategy use as reported by caregivers of children who did and did not receive pediatric intensive care unit (PICU) rehabilitation services. DESIGN: Qualitative substudy of the Wee-Cover prospective cohort study. SETTING: Two PICU sites. PARTICIPANTS: Wee-Cover enrolled caregivers (N=180) of children 1-17 years of age, who were admitted to a PICU for ≥48 hours. This study excluded participants missing relevant data (n=12). INTERVENTION: Not applicable. MAIN OUTCOME MEASURES: Qualitative data were gathered from open-ended questions on strategies within the Participation and Environment Measure at PICU discharge and 3 and 6 months post-PICU discharge. Strategies were classified as remedial or compensatory pending their content fit with 1 of 5 environmental chapters in the International Classification of Functioning, Disability, and Health-Children and Youth Version. Data on PICU-based rehabilitation services were obtained prospectively from electronic medical records and dichotomized (yes or no). RESULTS: Most caregiver strategies were compensatory, with more than half (60%) of the strategies pertaining to fostering supportive relationships. In contrast, strategies addressing the child's natural environment (12%), services (3%), and attitudes of others in the home (1%) were least commonly described. Similar themes were identified for caregivers whose children did and did not receive PICU rehabilitation services. CONCLUSIONS: Caregivers identify a range of strategies to facilitate their child's participation in home activities post-PICU discharge, but primarily report on strategies for addressing supports and relationships in the child's home environment. Results highlight areas warranting caregiver education to support the child's participation after critical illness.

RESUMO

BACKGROUND: Families play an important role meeting the care needs of individuals who require assistance due to illness and/or disability. Yet, without adequate support their own health and wellbeing can be compromised. The literature highlights the need for a move to family-centered care to improve the well-being of those with illness and/or disability and their family caregivers. The objective of this paper was to explore existing models of family-centered care to determine the key components of existing models and to identify gaps in the literature. METHODS: A scoping review guided by Arksey & O'Malley (2005) examined family-centered care models for diverse illness and age populations. We searched MEDLINE, PsycINFO, CINAHL and EMBASE for research published between 1990 to August 1, 2018. Articles describing the development of a family-centered model in any patient population and/or healthcare field or on the development and evaluation of a family-centered service delivery intervention were included. RESULTS: The search identified 14,393 papers of which 55 met our criteria and were included. Family-centered care models are most commonly available for pediatric patient populations (n = 40). Across all family-centered care models, the consistent goal is to develop and implement patient care plans within the context of families. Key components to facilitate family-centered care include: 1) collaboration between family members and health care providers, 2) consideration of family contexts, 3) policies and procedures, and 4) patient, family, and health care professional education. Some of these aspects are universal and some of these are illness specific. CONCLUSIONS: The review identified core aspects of family-centred care models (e.g., development of a care plan in the context of families) that can be applied to all populations and care contexts and some aspects that are illness specific (e.g., illness-specific education). This review identified areas in need of further research specifically related to the relationship between care plan decision making and privacy over medical records within models of family centred care. Few studies have evaluated the impact of the various models on patient, family, or health system outcomes. Findings can inform movement towards a universal model of family-centered care for all populations and care contexts.

RESUMO

OBJECTIVES: To evaluate functional outcomes and evaluate predictors of an unfavorable functional outcome in children following a critical illness. DESIGN: Prospective observational longitudinal cohort study. SETTING: Two tertiary care, Canadian PICUs: McMaster Children's Hospital and London Health Sciences. PATIENTS: Children 12 months to 17 years old, admitted to PICU for at least 48 hours with one or more organ dysfunction, were eligible. Patients not expected to survive, direct transfers from neonatal ICU and patients in whom long-term follow-up would not be able to be conducted, were excluded. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The primary endpoint was functional outcome up to 6 months post PICU discharge, measured using the Pediatric Evaluation of Disabilities Inventory Computer Adaptive Test. Secondary outcomes included predictors of unfavorable functional outcome, caregiver stress, health-related quality-of-life, and clinical outcomes such as mortality, length of stay, and PICU-acquired complications. One hundred eighty-two patients were enrolled; 78 children (43.6%) had functional limitations at baseline and 143 (81.5%) experienced functional deterioration following critical illness. Ninety-two (67.1%) demonstrated some functional recovery by 6 months. Higher baseline function and a neurologic insult at PICU admission were the most significant predictors of functional deterioration. Higher baseline function and increasing age were associated with slower functional recovery. Different factors affect the domains of functioning differently. Preexisting comorbidities and iatrogenic PICU-acquired morbidities were associated with persistent requirement for caregiver support (responsibility function) at 6 months. The degree of functional deterioration after critical illness was a significant predictor of increased hospital length of stay. CONCLUSIONS: This study provides new information regarding functional outcomes and the factors that influence meaningful aspects of functioning in critically ill children. Identifying patients at greatest risk and modifiable targets for improvement in PICU care guides us in developing strategies to improve functional outcomes and tailor to the rehabilitation needs of these patients and their families.

RESUMO

Recent innovative approaches to stabilize and crystallize GPCRs have resulted in an unprecedented breakthrough in GPCR crystal structures as well as application of the purified receptor protein in biophysical and biochemical ligand binding assays. However, the protein optimization process to enable these technologies is lengthy and requires iterative overexpression, solubilization, purification and functional analysis of tens to hundreds of protein variants. Here, we report a new and versatile method to screen in parallel hundreds of GPCR variants in HEK293 produced virus-like particles (VLPs) for protein yield, stability, functionality and ligand binding. This approach reduces the time and resources during GPCR construct optimization by eliminating lengthy protein solubilization and purification steps and by its adaptability to many binding assay formats (label or label-free detection). We exemplified the robustness of our VLP method by screening 210 GALR3-VLP variants in a radiometric agonist-based binding assay and a subset of 88 variants in a label-free antagonist-based assay. The resulting GALR3 agonist or antagonist stabilizing variants were then further used for recombinant protein expression in transfected insect cells. The final purified protein variants were successfully immobilized on a biosensor chip and used in a surface plasmon resonance binding assay.

RESUMO

RATIONALE: Critical illness survivors often experience permanent functional disability due to intensive care unit (ICU)-acquired weakness. The mechanisms responsible for long-term weakness persistence versus resolution are unknown. OBJECTIVES: To delineate cellular mechanisms underlying long-term weakness persistence in ICU survivors. METHODS: We conducted a nested, prospective study of critically ill patients mechanically ventilated for 7 days or longer. The patients were recruited from the RECOVER program and serially assessed over 6 months after ICU discharge. Twenty-seven of 82 patients consented to participate; 15 and 11 patients were assessed at 7 days and 6 months after ICU discharge, respectively. MEASUREMENTS AND MAIN RESULTS: We assessed motor functional capacity, quadriceps size, strength, and voluntary contractile capacity and performed electromyography, nerve conduction studies, and vastus lateralis biopsies for histologic, cellular, and molecular analyses. Strength and quadriceps cross-sectional areas were decreased 7 days after ICU discharge. Weakness persisted to 6 months and correlated with decreased function. Quadriceps atrophy resolved in 27% patients at 6 months. Muscle mass reconstitution did not correlate with resolution of weakness, owing to persistent impaired voluntary contractile capacity. Compared with Day 7, increased ubiquitin-proteasome system-mediated muscle proteolysis, inflammation, and decreased mitochondrial content all normalized at 6 months. Autophagy markers were normal at 6 months. Patients with sustained atrophy had decreased muscle progenitor (satellite) cell content. CONCLUSIONS: Long-term weakness in ICU survivors results from heterogeneous muscle pathophysiology with variable combinations of muscle atrophy and impaired contractile capacity. These findings are not explained by ongoing muscle proteolysis, inflammation, or diminished mitochondrial content. Sustained muscle atrophy is associated with decreased satellite cell content and compromised muscle regrowth, suggesting impaired regenerative capacity.

RESUMO

RATIONALE: Disability risk groups and 1-year outcome after greater than or equal to 7 days of mechanical ventilation (MV) in medical/surgical intensive care unit (ICU) patients are unknown and may inform education, prognostication, rehabilitation, and study design. OBJECTIVES: To stratify patients for post-ICU disability and recovery to 1 year after critical illness. METHODS: We evaluated a multicenter cohort of 391 medical/surgical ICU patients who received greater than or equal to 1 week of MV at 7 days and 3, 6, and 12 months after ICU discharge. Disability risk groups were identified using recursive partitioning modeling. MEASUREMENTS AND MAIN RESULTS: The 7-day post-ICU Functional Independence Measure (FIM) determined the recovery trajectory to 1-year after ICU discharge and was an independent risk factor for 1-year mortality. The 7-day post-ICU FIM was predicted by age and ICU length of stay. By 2 weeks of MV, ICU patients could be stratified into four disability groups characterized by increasing risk for post ICU disability, ICU and post-ICU healthcare use, and disposition. Patients less than 42 years with ICU length of stay less than 2 weeks had the best function and fewest deaths at 1 year compared with patients greater than 66 years with ICU length of stay greater than 2 weeks who sustained the worst disability and 40% 1-year mortality. Depressive symptoms (17%) and post-traumatic stress disorder (18%) persisted at 1 year. CONCLUSIONS: ICU survivors of greater than or equal to 1 week of MV may be stratified into four disability groups based on age and ICU length of stay. These groups determine 1-year recovery and healthcare use and are independent of admitting diagnosis and illness severity. Clinical trial registered with www.clinicaltrials.gov (NCT 00896220).

RESUMO

OBJECTIVES: Caring for community-residing patients with heart failure can affect caregivers' emotional wellbeing. However, few studies have examined caregivers' well-being longitudinally, or identified factors associated with positive and negative outcomes. The objective of this longitudinal cohort study was to examine changes in caregivers' well-being over time, and to identify patient and caregiver factors associated with positive and negative outcomes. METHOD: Fifty caregiver/heart failure patient dyads were recruited from an acute care facility and followed in the community. All participants completed surveys at hospital admission and 3, 6 and 12 months later. Caregivers completed assessments of depression symptoms and positive affect and standardized measures to capture assistance provided, mastery, personal gain, social support, participation restriction, and patients' behavioral and psychological symptoms. From patients, we collected demographic characteristics and health-related quality of life. Individual Growth Curve modelling was used to analyze the data. RESULTS: Caregivers' negative and positive emotions remained stable over time. Depression symptoms were associated with higher participation restriction in caregivers. Positive affect was associated with more personal gain and more social support. Patients' health-related quality of life and their behavioral and psychological symptoms were not significantly associated with caregivers' emotional outcomes. CONCLUSION: Interventions should be offered based on caregivers' needs rather than patients' health outcomes, and should focus on fostering caregivers' feelings of personal gain, assisting them with securing social support, and engaging in valued activities.

RESUMO

OBJECTIVE: To identify caregiver-, stroke survivor-, and caregiving situation-related factors that are associated with caregivers' restriction from participation in their normative activities (ie, participation restriction) over the first 2 years poststroke. DESIGN: Longitudinal cohort study. SETTING: Acute care facilities and community. PARTICIPANTS: A secondary data analysis of caregiver/survivor dyads (N=399). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Data were collected at 1, 3, 6, 12, 18, and 24 months poststroke. The primary outcome was caregivers' participation restriction and was assessed using the Caregiver Impact Scale. Caregivers also provided demographic information and completed standardized measures to capture assistance provided, mastery, and depression. From stroke survivors we collected demographic characteristics, stroke severity, and cognitive and physical functioning. Data were analyzed using individual growth curve modeling. RESULTS: Participation restriction level improved over time. Caregiver factors associated with restricted participation included younger age, being employed, higher depression, and lower mastery level. Stroke survivor factors associated with caregivers' restricted participation included hemorrhagic stroke, more severe stroke, more physical and memory impairments, and lower participation. Significant factors related to the caregiving situation included providing high levels of assistance and caring for a spouse. CONCLUSIONS: Depressed younger caregivers, with low levels of mastery, who provide high-intensity support to spouses with cognitive difficulties may be at risk. Screening for these factors may help identify stroke families at risk for poor outcomes and may be used to more efficiently allocate health resources.

RESUMO

OBJECTIVE: To qualitatively explore daughters' experiences with and response to holding multiple roles while providing post-stroke care to a parent. DESIGN: Qualitative study using a descriptive approach. Semi-structured interviewing was used. Interviews were recorded, transcribed and analyzed to develop themes. SETTING: General community of a metropolitan city. PARTICIPANTS: Twenty-three adult daughters caring for a community-dwelling parent who had suffered a stroke. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Not applicable. RESULTS: Role overload is a salient issue for daughter caregivers. This overload is best captured by the analogy of "juggling" multiple role demands and responsibilities. Two key themes suggest that role overload resulting from parent care affects daughters': 1) valued relationships (e.g. challenges develop in their relationship with children and partner); and 2) ability to participate in valued activities (e.g. reduced involvement in leisure activities and restricted employment). CONCLUSIONS: Future support efforts should help daughters manage the caregiving role in light of other responsibilities. This can mitigate overload-related strain in valued relationships and decreased participation in valued activities, thereby contributing to better health and well-being for daughter caregivers.

RESUMO

OBJECTIVE: Examine feasibility of conducting a randomized controlled trial of the Timing it Right Stroke Family Support Program (TIRSFSP) and collect pilot data. DESIGN: Multi-site mixed method randomized controlled trial. SETTING: Acute and community care in three Canadian cities. SUBJECTS: Caregivers were family members or friends providing care to individuals who experienced their first stroke. INTERVENTION: The TIRSFSP offered in two formats, self-directed by the caregiver or stroke support person-directed over time, were compared to standard care. MAIN MEASURES: Caregivers completed baseline and follow-up measures 1, 3 and 6 months post-stroke including Centre for Epidemiological Studies Depression, Positive Affect, Social Support, and Mastery Scales. We completed in-depth qualitative interviews with caregivers and maintained intervention records describing support provided to each caregiver. RESULTS: Thirty-one caregivers received standard care (n=10), self-directed (n=10), or stroke support person-directed (n=11) interventions. We retained 77% of the sample through 6-months. Key areas of support derived from intervention records (n=11) related to caregiver wellbeing, caregiving strategies, patient wellbeing, community re-integration, and service delivery. Compared to standard care, caregivers receiving the stroke support person-directed intervention reported improvements in perceived support (estimate 3.1, P=.04) and mastery (estimate .35, P=.06). Qualitative caregiver interviews (n=19) reflected the complex interaction between caregiver needs, preferences and available options when reporting on level of satisfaction. CONCLUSIONS: Preliminary findings suggest the research design is feasible, caregivers' needs are complex, and the support intervention may enhance caregivers' perceived support and mastery. The intervention will be tested further in a large scale trial.
