Quality of Life Trajectories Among Stroke Survivors and the Related Changes in Caregiver Outcomes: A Growth Mixture Study

Caregiver burden after stroke: a 10-year follow-up study of Polish caregivers for stroke patients

BACKGROUND

A long-term assessment of stroke outcomes from the perspectives of patients and their caregivers is important for optimising long-term post-stroke care. The extended effects of stroke caregiving, particularly caregiver burden beyond 5 years since stroke, remain to be determined. Hence, this study aimed to determine caregiver burden at 10 years after stroke, compare the burden severity at 10 years with its levels at 5 years and 6 months after stroke, and identify predictors of the burden severity at 10 years post-stroke.

METHODS

A longitudinal follow-up study including a group of first-ever stroke patients/informal continuous caregivers pairs was followed for 10 years and interviewed face-to face at their home setting. Caregiver burden was evaluated with the Caregiver Burden Scale. Potential predictors were examined using standardised measures and identified by applying the Classification and Regression Tree.

RESULTS

A total of 40 caregiver/patient pairs participated in the study. At 10 years, 47.5% of the caregivers experienced a considerable burden. This was more than after 5 years (17.5%) and comparable to that after 6 months (37.5%), p < 0.003. Longer time spent caregiving, caregivers' weaker sense of coherence, more severe stroke, and caregivers' anxiety were the independent predictors of considerable burden 10 years after stroke.

CONCLUSIONS

Caregivers' burden in the late chronic post-stroke phase is a significant problem, as nearly half of the caregivers experience a substantial burden. This problem mainly concerns individuals who spend at least 7 h daily caregiving and have a lower Sense of Coherence. The long-term evaluation of stroke consequences reported by stroke patients and their caregivers can be an important source of information for healthcare professionals in order to optimise the care and support they provide at various stages of life after stroke.

Developmental trajectory of care dependency in older stroke patients

Background

Stroke is the leading cause of death in China. Older stroke survivors often have other chronic conditions, not only musculoskeletal deterioration due to age, but also changes in body image that can be brought on by stroke and other diseases, making them unable to take good care of themselves and dependent on others. The degree of dependency affects the rehabilitation progress of stroke survivors and shows dynamic changes that need to be recognized.

Objectives

This study investigates the trajectory of dependency changes in older stroke patients with comorbidities and analyze the influencing factors.

Methods

Grounded in the Chronic Illness Trajectory Framework (CITF), a longitudinal study was conducted from February 2023 to October 2023, tracking 312 older stroke patients with comorbidities admitted to two tertiary hospitals in Guangzhou. Care dependency levels were assessed using Care Dependency Scale on admission day 5 (T0), at discharge (T1), 1 month post-discharge (T2), and 3 months post-discharge (T3). Growth Mixture Model were utilized to identify trajectory categories, and both univariate analysis and multivariate logistic regression methods were employed to explore factors associated with different developmental trajectories.

Results

A total of four developmental trajectories were fitted, C1 (high independence-slow increased group, 52.0%), C2 (moderate independence-rapid increased group, 13.0%), C3 (moderate independence-slow increased group, 25.0%), and C4 (low independence-increased and decreased group, 10.0%). Length of hospital stay, place of residence, level of social support, residual functional impairments, NIHSS score, and BI index independently influence the trajectory categories.

Conclusion

There is heterogeneity in care dependency among older stroke patients with comorbidities. Most patients gradually reduce their dependency and become more independent, but others remain dependent for an extended period of time. It is recommended to focus on patients who live in rural areas, have low social support, have high admission NIHSS scores and have residual functional impairment, and provide them with personalized continuity of care and rehabilitation services in order to reduce care dependency and the burden of care, and to improve patients' quality of life.

Stroke disease-specific quality of life trajectories and their associations with caregivers' anxiety, depression, and burden in stroke population: a longitudinal, multicentre study

AIMS

The aims of this study were to: (i) test if there are clusters of stroke survivors who experience distinct trajectories of quality of life (QOL) from hospital rehabilitation discharge to 12-month follow-up; (ii) test if any sociodemographic or clinical variables predict this class membership; and (iii) examine the associations between the clusters of stroke survivors' and their caregivers' trajectories of anxiety, depression, and burden over time.

METHODS AND RESULTS

A total of 415 stroke survivors and their caregivers were recruited in Italy for this 1-year, longitudinal, multicentre prospective study, filling out a survey at five time points. We found two distinct trajectories of change in stroke survivors' psychological QOL (i.e. Memory, Communication, Emotion, and Participation). The first trajectory (86% of the survivors) included those who started with greater levels of QOL and improved slightly to markedly in all psychological domains, while the second trajectory (14% of the survivors) comprised those who started with lower overall levels of psychological QOL and experienced a worsening or no changes at all in these dimensions up to 12-month follow-up. Very few clinical and sociodemographic variables at baseline predicted class membership. Finally, caregivers of those patients who experienced no change or a worsening in psychological QOL reported greater distress and burden over time.

CONCLUSION

Our results highlight the need for more tailored interventions to improve patients' psychological QOL and consequently their caregivers' well-being. This requires a shift from a stroke survivor-centred approach to a stroke survivor- and caregiver-centred one.

The caregiver burden of informal caregivers for stroke patients with and without dysphagia: A multi-center, cross-sectional study in Türkiye

Objectives

The aim of this study was to investigate the caregiver burden (CB) of informal caregivers for stroke survivors with and without dysphagia and to assess the relationship between the CB levels of informal caregivers for stroke survivors with dysphagia, patients' swallowing-related quality of life (QoL), and patients' stroke-specific QoL.

Patients and methods

This multi-center, prospective, cross-sectional study included a total of 120 stroke patients (76 males, 44 females; mean age: 61.1±12.3 years; range, 19 to 86 years) between October 2019 and 2020. Of the patients, 57 had dysphagia and 63 had no dysphagia. The Functional Oral Intake Scale (FOIS) was used to classify the degree of functional dietary limitation caused by each patient's swallowing impairment. Patients and caregivers completed the Eating Assessment Tool (EAT-10), Swallowing Quality of Life (SWQoL) questionnaire, Stroke Impact Scale (SIS), and the Zarit Caregiver Burden Interview (ZBI).

Results

The CB levels were higher in those caring for stroke patients with dysphagia than in those caring for stroke patients without dysphagia. Caregiver burden was found to be associated with patients' swallowing-related QoL and stroke-related QoL. Significant predictors of high CB scores (F=2.55, R2=0.59; p=0.007) were being an employed caregiver (B=17.48, p=0.003), being a caregiver with high school (B=-19.6, p=0.03), and secondary school (B=-16.28, p=0.02) educational status, being son, daughter (B=30.63, p=0.007) or other relative of the patient (B=20.06, p=0.01), lower FOIS stage (B=-3.14, p=0.011), lower SWQoL (B=0.52, p=0.009) and lower SIS (B=-0.37, p=0.04) scores.

Conclusion

Caregivers of stroke patients with dysphagia suffer from a higher CB than those without dysphagia. In stroke patients with dysphagia, swallowing-related QoL is associated with the QoL levels of stroke patients and the CB levels of their caregivers. Employment status, educational status of caregiver, caregiver's relativity to the patient, FOIS stage, swallowing and stroke related QoL of the patients are factors related to burden levels of caregivers of stroke patients with dysphagia. These results may help health professionals to understand dysphagia as an essential source of CB and consider it, while planning treatments.

Socioeconomic status and health-related quality of life after stroke: a systematic review and meta-analysis

BACKGROUND

Socioeconomic status (SES) is associated with stroke occurrence and survival following stroke but its association with health-related quality of life (HRQoL) following stroke remains uncertain. We performed a systematic review and meta-analysis to examine the association between SES and HRQoL after stroke.

METHODS

PubMed, SCOPUS, EMBASE, and Web of Science were searched to identify relevant cohort and case-control studies between January 2000 and May 2022. Two authors screened titles, abstracts and full text articles. One author extracted data from all included studies. Meta-analyses were performed for studies with comparable measurements of SES and HRQoL. Random effects models were used to estimate pooled summary standardised mean differences in HRQoL by SES.

RESULTS

Out of 1,876 citations, 39 studies incorporated measurement of overall HRQoL following stroke and were included in the systematic review, with 17 studies included in the meta-analyses. Overall, reports including education, income, occupation and work status effects on HRQoL after stroke were inconsistent among all included 39 studies. In the global meta-analysis of 17 studies, HRQoL among survivors of stroke was lower in the low SES group than in the high SES group (standardised mean difference (SMD) -0.36, 95% CI -0.52, -0.20, p < 0.0001). When using education and income indicators separately, summary effects were similar to those of the global analysis (low versus high education SMD -0.38, 95% CI -0.57, -0.18, p < 0.0001; low versus high income SMD -0.39, 95% CI -0.59, -0.19, p < 0.0001).

CONCLUSIONS

Across all SES indicators, people with stroke who have lower SES have poorer overall HRQoL than those with higher SES. Accessibility and affordability of poststroke support services should be taken into consideration when planning and delivering services to people with low SES.

Dyadic psycho-social interventions for stroke survivors and family caregivers: A systematic review and meta-analysis of randomized controlled trials

AIMS AND OBJECTIVES

To describe dyadic psycho-social intervention measures and to evaluate their influence on stroke survivors and caregiver's functional independence, quality of life, depression, anxiety, self-efficacy and coping ability.

BACKGROUND

Because of the importance of dyadic intervention and the seriousness of the psycho-social problems of stroke survivors and caregivers, understanding the influence of dyadic psycho-social interventions is vital.

DESIGN

A systematic review and meta-analysis based on PRISMA guidelines.

DATA SOURCES

Nine databases were systematically searched for randomized controlled trials submitted from 1910 to 4 July 2022.

METHODS

The included papers were evaluated for quality, and quantitative data were standardly extracted and analysed by meta-analysis, followed by synthesis. The meta-analysis was carried out using Review Manager 5.4 software.

RESULTS

Fifteen randomized controlled trials were included (n = 2190 for patients, and n = 1933 for caregivers). Study results showed that dyadic psycho-social interventions significantly alleviated the depressive symptoms of patients, obviously improved the ability to function independently of patients and more quickly alleviated the care burden of caregivers.

CONCLUSIONS

This study provided moderate support for the benefits of dyadic psycho-social intervention in improving survivor and caregiver's functional independence, quality of life, depression, anxiety, self-efficacy and care burden. Nevertheless, due to limitations of the study, it was deemed necessary that this topic is studied further.

RELEVANCE TO CLINICAL PRACTICE

This review suggests that dyadic psycho-social interventions should be considered as effective strategies for decreasing psycho-social problems of stroke survivors and caregivers, and provides evidence for the formulation of targeted intervention programs. The personalized implementation of such interventions should be the focus of clinical practice.

Trajectories of post-stroke quality of life and long-term prognosis: Results from an eleven-year prospective study

PURPOSE

The relationship between quality of life (QoL) and long-term prognosis in stroke patients is still unclear. We explored physical and mental QoL trajectories during the first six months after stroke and determined the associations between trajectories and long-term prognosis in patients with first-ever ischemic stroke.

METHODS

Included were 733 participants from a prospective study. QoL was assessed with the 12-item Short Form Survey (SF-12) at baseline, 3 and 6 months. Patients' prognoses (stroke recurrence and death) were identified from 2010 to 2021. The latent class growth model (LCGM) was used to identify distinct trajectories of physical and mental QoL measured over the first 6 months. We employed the Cox model or Fine-Gray model for prognoses to examine the associations between QoL trajectories and prognosis.

RESULTS

Five trajectories of physical QoL and five trajectories of mental QoL were identified. For physical QoL of the Poor-Improved, and Moderate-Impaired trajectory versus Moderate-Improved trajectory, the hazard ratio (HR) for death was 2.39 (1.14 to 5.02), and 2.03(0.93 to 4.44); the HR for recurrence was 1.56 (0.83 to 2.94) and 2.33 (1.28 to 4.24). For mental QoL of the Moderate-Impaired trajectory versus the Moderate-Improved trajectory, the HR for death was 2.48 (1.21 to 5.07). The results were robust in the sensitivity analysis.

CONCLUSION

QoL during the first six months after ischemic stroke can be categorized into distinct groups. Change in QoL was associated with long-term survival. Secondary prevention of recurrent strokes might rely more on improving patients' physical QoL.

Area-level and individual-level socio-economic differences in health-related quality of life trajectories: Results from a 10-year longitudinal stroke study

BACKGROUND

We examined area-level (aSES) and individual-level (iSES) socio-economic status on trajectories of HRQoL to 10 years following stroke.

METHODS

Participants with strokes between 1/5/1996 and 30/4/1999 completed the Assessment of Quality of Life instrument (AQoL, range: -0.04 [worse than death] to 0 [death] to 1 [full health]) at ≥one of 3month, 6-month, 1-year, 2-year, 3-year, 4-year, 5-year, 7-year and 10-year interviews after stroke. Sociodemographic and health information were collected at baseline. We derived aSES from postcode using the Australian Socio-Economic Indexes For Area (2006) (categories: high, medium, low), and iSES from lifetime occupation (categories: non-manual, manual). Multivariable linear mixed effects modelling was used to estimate trajectories of HRQoL over 10 years, by aSES and iSES, adjusting for age, sex, cardiovascular disease, smoking, diabetes, stroke severity, stroke type, and the time influence on age and health conditions.

RESULTS

Of 1,686 participants enrolled, we excluded 239 with 'possible' stroke and 284 with missing iSES. Among the remaining 1,163 participants, 1,123 (96.6%) had AQoL assessed at ≥3 timepoints. In multivariable analysis, over time, people in the medium aSES group had mean 0.02 (95% CI -0.06, 0.02) greater reduction in AQoL score, and people in the low aSES group had mean 0.04 (95% CI, -0.07, -0.001) greater reduction, than those in the high aSES group. Manual workers had an average 0.04 (95% CI, -0.07, -0.01) greater reduction in AQoL score over time than non-manual workers.

CONCLUSIONS

Over time, HRQoL declines in all people with stroke, declining most rapidly in lower SES groups.

The effects of a family-focused dyadic psychoeducational intervention for stroke survivors and their family caregivers: A randomised controlled trial

BACKGROUND

Stroke can cause a variety of physical and psychosocial disturbances for both survivors and their family caregivers (i.e., stroke dyads). Dyadic psychoeducation appears to be a promising approach for providing knowledge of stroke and self-care or caregiving skills to improve stroke dyads' health outcomes. Therefore, a family-focused psychoeducation intervention was designed and tested to improve the health outcomes of stroke dyads.

OBJECTIVE

To examine the effects of a family-focused dyadic psychoeducational intervention on the functional and psychosocial outcomes of stroke survivors and family caregivers.

DESIGN

A single-blinded, parallel-group randomised controlled trial with repeated-measures design.

SETTINGS

Two general hospitals and one rehabilitation facility in Jinan, China.

PARTICIPANTS

Stroke survivors and family caregivers (N = 162 dyads).

METHODS

The dyads were randomly allocated to either psychoeducation or control group with usual care only (N = 81 dyads per group). The intervention included three structured face-to-face education sessions (one hour per session) in hospital pre-discharge and four weekly telephone counselling calls post-discharge. Study outcomes included survivor functioning and caregiver burden (primary outcomes), and other secondary outcomes (i.e., caregiving competence, dyads' coping, depressive and anxiety symptoms, family functioning, and dyadic relationship, as well as survivor healthcare utilisation and caregiving-related injury). Data were collected at baseline (T₀) and immediately (T₁) and 3 months post-intervention (T₂). The intervention effects were estimated using generalised estimating equation models.

RESULTS

Participants in the psychoeducation group revealed significantly greater reductions on caregiver burden than the control group at T₁ (β = -6.01, p = 0.026) and T₂ (β = -6.73, p = 0.039), but non-significant effects on survivor functioning, except in emotion domain at T₁ (β = 7.22, p = 0.015). In addition, the intervention demonstrated significantly greater improvements on caregiving competence (β = 0.98, p = 0.013; β = 1.58, p < 0.001), survivors' depressive symptoms (β = -1.56, p = 0.007; β = -2.06, p = 0.005), and dyadic relationship (β = 0.26, p = 0.012; β = 0.27, p = 0.022) at T₁ and T₂, as well as on survivor coping at T₂ (β = 6.73, p = 0.008).

CONCLUSIONS

Our study added values on the benefits of family-focused dyadic psychoeducation to routine stroke rehabilitation and family care. Future research can evaluate its long-term effects for families of stroke survivors with diverse socio-demographic and stroke-related characteristics.

Combined Aerobic Exercise and Virtual Reality-Based Upper Extremity Rehabilitation Intervention for Chronic Stroke: Feasibility and Preliminary Effects on Physical Function and Quality of Life

Objectives

To (1) examine the feasibility of combining lower extremity aerobic exercise (AEx) with a virtual reality (VR) upper extremity (UE) rehabilitation intervention and (2) provide an estimate of effect size for the combined intervention on UE function, aerobic capacity, and health-related quality of life.

Design

Single-group feasibility trial.

Setting

Research laboratory.

Participants

Community-dwelling individuals with mild to moderate impairment of the UE at least 6 months post stroke (N=10; male, n=6; female n=4; mean age, 54 years).

Intervention

All participants received 18 sessions over a nominal 2-3 sessions per week schedule of a combined AEx and VR-UE rehabilitation intervention. During each session, participants completed 15 minutes of lower extremity AEx followed by playing a VR-UE rehabilitation game for approximately 20 minutes.

Main Outcome Measures

Feasibility was evaluated by metrics of adherence, retention, treatment acceptability, data completeness, and adverse events. UE function, aerobic capacity (peak oxygen consumption [Vo2peak]), and quality of life were assessed with the Fugl-Meyer Assessment of Upper Extremity (FMA-UE), expired gas exchange analysis, and Stroke Impact Scale (SIS), respectively.

Results

Adherence was 100%, and there were no withdrawals or losses to follow-up to report. Participants completed the intervention in 49±14 days. Cohen's dz effect size calculations indicated the intervention elicited medium effects on FMA-UE (dz =0.50) and SIS memory domain (dz =0.46) and large effects on absolute Vo2peak (dz =1.46), relative Vo2peak (dz =1.21), SIS strength (dz =1.18), and SIS overall recovery domains (dz =0.81).

Conclusions

Combining lower extremity AEx and VR-UE rehabilitation appears feasible in the clinical research setting. Fifteen minutes of lower extremity AEx performed at vigorous intensity appears to elicit clinically meaningful benefits in chronic stroke. Further examination of the combination of lower extremity AEx and VR-UE rehabilitation and its effects on physical function and quality of life is warranted.

The preparedness assessment for the transition home after stroke predicts key domains of caregiver health

BACKGROUND

Caregivers of stroke survivors often experience adverse health effects due to poor preparation.

OBJECTIVES

We evaluate the concurrent and predictive validity of the Preparedness Assessment for the Transition Home after Stroke (PATH-s) family caregiver assessment tool relative to important domains of caregiver health and stroke survivor outcomes.

METHODS

A convenience sample of caregivers (N = 183) was assessed on several health-related quality of life instruments prior to stroke survivor discharge (T1), and at 30-days (T2) and 90-days (T3) post-discharge.

RESULTS

Caregivers completed assessments at T1 (N = 183), T2 (N = 116, 63%), and T3 (N = 97, 53%). At T1, the PATH-s demonstrated concurrent validity with depressive symptoms (r = -0.26, p < .001), global health (r = 0.45 p < .001) and activation (r = 0.34, p < .001). The PATH-s also has predicted improvements in T2 outcomes including depressive symptoms (r_adj = -0.21, p < .05), global health (r_adj = 0.30, p < .01), perceived stress (r_adj = -0.30, p < .01), activation (r_adj = 0.21, p < .05), caregiving-specific health-related quality of life (r = 0.23, p < .05), and caregiver strain (r = -0.36, p < .001). At T3, higher scores on the PATH-s were a significant predictor for improvements in activation (r_adj = 0.24, p < .05).

CONCLUSION

The PATH-s demonstrates good concurrent and predictive validity and predicts important domains relevant to caregiver well-being. This can be used to identify gaps in caregiver preparedness so interventions can be tailored to optimize the transition home and mitigate adverse effects of caregiving.

Intracerebral Hemorrhage

PURPOSE OF REVIEW

Nontraumatic intracerebral hemorrhage (ICH) is the second most common type of stroke. This article summarizes the basic pathophysiology, classification, and management of ICH and discusses the available evidence on therapy for hematoma, hematoma expansion, and perihematomal edema.

RECENT FINDINGS

Current available data on potential therapeutic options for ICH are promising, although none of the trials have shown improvement in mortality rate. The literature available on reversal of anticoagulation and antiplatelet agents after an ICH and resumption of these medications is also increasing.

SUMMARY

ICH continues to have high morbidity and mortality. Advances in therapeutic options to target secondary brain injury from the hematoma, hematoma expansion, and perihematomal edema are increasing. Data on reversal therapy for anticoagulant-associated or antiplatelet-associated ICH and resumption of these medications are evolving.

Improving Caregiver Health through Systematic Assessment and a Tailored Plan of Care

Caregivers often experience strain and negative effects on their well-being. We tested the effects of a caregiver assessment and tailored care plan for caregivers of patients transitioning home from an inpatient rehabilitation facility (IRF), a study involving two groups: usual care (n = 225) (preimplementation) and intervention (postimplementation) (n = 215). Caregivers in the intervention group were assessed using the 25-item self-reported Preparedness Assessment for the Transition Home during the IRF stay. A tailored care plan was implemented in response to the assessment. Caregivers in both groups completed the Modified Caregiver Strain Index and Global Health Scale at 30- and 90-day postdischarge. After adjusting for baseline and demographics, caregivers in the intervention group reported lower strain (p < .01) and better overall health (p < .05) at 30-day post-IRF discharge, relative to usual care. Implementing a systematic caregiver assessment and tailored care plan in the IRF may mitigate the adverse effects of caregiving.

Contributors to Poststroke Dysphagia-Related Caregiver Burden

Purpose Caregiver burden negatively impacts both stroke survivor and caregiver well-being. Thus, it is important to better understand the individual- and dyadic-level variables that may contribute to dysphagia-related caregiver burden. The aim of this preliminary study was to identify survivor-, caregiver-, and dyadic-specific factors associated with burden in couples experiencing poststroke dysphagia. Method Twenty-eight stroke survivors ("care recipients") with dysphagia and their spouses ("caregivers") participated. Care recipients and caregivers completed a survey from which scores for the following variables were derived: dysphagia-related caregiver burden, survivor- and spouse-perceived impact of dysphagia on mealtimes (social, mealtime logistics), dyadic congruence on perceived impact, International Dysphagia Diet Standardisation Initiative Functional Diet Scale, Swallowing-Related Quality of Life Scale, and Stroke Impact Scale (cognitive, emotional, physical, and social domains). Spearman's rho and point biserial correlation coefficients were calculated to determine the factors related to caregiver burden. Results Increased burden was significantly associated with greater care recipient- and spouse-perceived impact of dysphagia on mealtime logistics; however, burden was not associated with measures of dyadic congruence of perceived impact. Notably, increased burden was also associated with increased diet restrictiveness and decreased swallow-specific quality of life. Dysphagia-related caregiver burden was not associated with measures of stroke impact/severity across any domain. Conclusions Factors related to dysphagia-related caregiver burden are multifactorial and include both care recipient (e.g., International Dysphagia Diet Standardisation Initiative Functional Diet Scale, Swallowing-Related Quality of Life Scale, perceived impact of dysphagia on mealtime logistics) and caregiver (e.g., perceived impact of dysphagia on mealtime logistics) variables. The results of this preliminary investigation support the need to incorporate aspects of counseling and family-centered care into our management practices, a growing area of interest for speech-language pathologists.

Caregivers' Loss of the Dyadic Experience after Their Care Partners' Death

Little is known about the experience of family caregivers when their care partner dies and their dyadic relationship comes to an end. This study qualitatively examined and characterized the loss of the dyadic experience for the caregiver after the death of their care partner. Data was accrued as part of a randomized clinical trial in 29 older hospice caregivers. Iterative thematic analysis focused on dyadic processes before, during and post death. Using two relational parameters from Relational Turbulence Theory resulted in a preliminary characterization of a new concept-dyadic dissolution as a cognitive and affective process whereby a remaining member of a dyad experiences relational uncertainty and partner interference while adapting (or not) to the death of their care partner. Findings suggest that asking several open-ended questions about the dyadic relationship will enable assessment for any continuing impact of relational uncertainty and partner interference on bereaved caregivers.

Longitudinal study of quality of life in acquired brain injury: A self- and proxy-report evaluation

After an acquired brain injury (ABI), the person remains with several impairments and disabilities that cause a decrease in his/her quality of life (QoL), which could change over time. The objective of the study was to analyse the evolution patterns of QoL in a sample of persons with ABI for one-year as well as the differences in proxy- and self-report versions of a QoL instrument. Method: The sample comprised 402 persons with ABI with ages ranging between 18 and 91 years, whom 36.20% had had the accident recently (i.e., three years or less). Patients, professionals and relatives responded at three evaluation points to the CAVIDACE scale, an ABI-specific QoL tool. Results: ANOVAs showed an improvement in QoL in the two follow-ups; the improvement was especially significant in the period between baseline and six months. The respondent factor did not interact with the evaluation time, but significant differences were found between respondents, with scores of patients higher than that for proxies. Finally, the QoL’s evolution interacts with the time elapsed since injury, showing significant improvements in the most recent group (i.e., three years or less). Conclusions: QoL must be considered from the earliest moments after ABI to obtain more significant improvements.

Predictive Factors of Self-Reported Quality of Life in Acquired Brain Injury: One-Year Follow-Up

Background: The sequelae and disabilities that follow an acquired brain injury (ABI) may negatively affect quality of life (QoL). The main objective of the study is to describe the QoL after an ABI and identify the predictors of a better QoL. Methods: Prospective cohort study with follow-up measurement after one-year. The sample comprised 203 adults with ABIs (64% male) aged 18–86 years (M = 53.01, SD = 14.44). Stroke was the main etiology of the injury (55.7%), followed by a TBI (32.8%), and the average time since injury was 8 years (M = 8.25, SD = 7.83, range = 0.5–47.5). Patients assessed their QoL through the scale Calidad de Vida en Daño Cerebral (CAVIDACE self-reported version; “quality of life in brain injury” in English), an ABI-specific tool based on the eight-domain QoL model. Other variables measured were: depression, self-awareness, community integration, resilience, and social support at baseline and one-year follow-up. Results: The studied factors showed few significant changes over time. The analyses showed statistically significant differences in QoL scores in several sociodemographic (age, civil status, education, legal capacity, and dependency), injury-related (time, location, and comorbidity), rehabilitation, and personal-social variables (self-awareness, depression, social support, resilience, and community integration). The levels of dependency, depression, and satisfaction with social support were independent predictors of the total QoL score one-year follow-up. Conclusions: QoL after ABI depends on multiple elements that must be considered. There are factors such as satisfaction with social support, depression, community integration, and resilience that must be monitored throughout the rehabilitation process.

Stroke disease-specific quality of life trajectories after rehabilitation discharge and their sociodemographic and clinical associations: A longitudinal, multicentre study

AIM

To investigate the longitudinal growth trajectories of disease-specific quality of life (QoL) dimensions and their associations over 1 year.

DESIGN

A longitudinal design. Data were collected between February 2015-May 2017.

METHODS

Four hundred and fifteen stroke survivors (mean age 70.6 years; 81% ischaemic stroke) were recruited after discharge from rehabilitation hospitals and were followed up every 3 months for 1 year. Changes in Stroke Impact Scale (SIS) dimension scores were evaluated using hierarchical linear models (HLMs) and linear, logarithmic, quadratic, and cubic time slope.

RESULTS

We observed a significant linear and quadratic increase in most SIS dimensions from the baseline to 12-month follow-up, especially in physical dimensions. The communication dimension was stable over time, while the memory dimension increased only linearly. Higher physical dimension scores were significantly associated with lower age, hypercholesterolaemia, and better physical functioning at baseline, while higher communication was associated with lower age, better physical functioning, and a diagnosis of peripheral vascular disease. Better memory was associated with lower age, married status, better physical functioning, and left-hemisphere stroke. Better participation was associated with lower age and better physical functioning. No significant associations were observed for emotion.

CONCLUSIONS

This study provides important information about the trajectories of stroke survivors' specific QoL and their associated variables.

IMPACT

Stroke has a great impact on stroke survivors' QoL. Disease-specific QoL significantly increases from the baseline to 12-month follow-up, especially in physical dimensions. Lower age, hypercholesterolaemia, better physical functioning, and diagnosis of peripheral vascular disease seem to be associated with better QoL. Through the analyses of associated variables, we identified stroke survivors who are more at risk and who need more tailored interventions to improve their physical, psychological, emotional, and social dimensions.

Effectiveness of dyadic interventions to improve stroke patient-caregiver dyads' outcomes after discharge: A systematic review and meta-analysis study

BACKGROUND

Because of the importance of a dyadic approach, it is necessary to conduct a systematic review to identify which dyadic intervention could be implemented for stroke survivor-caregiver dyads after discharge from the rehabilitation hospital to improve outcomes.

AIMS

The aims were to systematically review the evidence to identify which dyadic interventions have been implemented in stroke survivor-caregiver dyads to improve stroke survivor-caregiver dyads' outcomes and to analyse, through a meta-analysis, which intervention was found to be the most effective.

METHODS

A systematic review and meta-analysis were conducted using the following electronic databases: PubMed, CINAHL and PsycInfo. Randomized controlled trials (RCTs) and quasi-RCT studies published within the last 10 years were included. Quantitative data were extracted from papers included in the review using the standardized data extraction tool from JBI-MAStARI. Pooled effects were analysed between the experimental and control groups for each outcome.

RESULTS

Sixteen studies involving 2997 stroke survivors (male gender=58%) and 2187 caregivers (male gender=25%) were included in this review. In 16 studies, which were subdivided into three quasi-RCTs and 13 RCTs, the application of dyadic interventions for stroke survivors and caregivers was systematically reviewed, but only a few of these identified a significant improvement in the stroke survivors' and caregivers' outcomes of its intervention group. Dyadic interventions showed a significant effect on stroke survivors' physical functioning (p=0.05), memory (p<0.01) and quality of life (p=0.01) and on caregivers' depression (p=0.05).

CONCLUSIONS

This study provides moderate support for the use of a dyadic intervention to improve stroke survivors' physical functioning, memory and quality of life and caregiver depression.

Role of Spirituality on the Association Between Depression and Quality of Life in Stroke Survivor-Care Partner Dyads

BACKGROUND

Little is known about the protective effect of spirituality on the association between known risk factors such as depression and quality of life (QOL) in stroke survivor-care partner dyads. Therefore, the aim of this study was to evaluate the moderating role of spirituality on the association between depressive symptomatology and QOL in stroke survivor-care partner dyads.

METHODS AND RESULTS

Longitudinal design with 223 stroke survivor-care partner dyads enrolled at survivor discharge from rehabilitation hospitals. Data collection was performed over 12 months. We measured survivors' and care partners' depression, quality of life, and spirituality. Examining the moderating role of spirituality on the association between depressive symptoms and QOL within survivor-care partner dyads, we used a traditional Actor-Partner-Interdependence Model and a basic Actor-Partner-Interdependence Model moderation model for a mixed variable. Survivors (51% male) and care partners (66% female) were 70.7 and 52.3 years old, respectively. The survivor's spirituality significantly moderated the association between care partner depressive symptomatology and survivor psychological QOL (B=0.03, P<0.05) and moderated the association between care partner depressive symptoms and care partner physical (B=0.05, P<0.001) and psychological (B=0.04, P<0.001) QOL. The care partner's own level of spirituality was significantly positively associated with their physical QOL (B=0.28, P<0.001).

CONCLUSIONS

The findings from this study have broad implications for the role of spirituality in relation to QOL in medical-health contexts and the importance of examining such concepts within a dyadic framework. Greater awareness of the importance of spirituality among clinicians and nurses may improve cultural competence in healthcare services.

The Perceived Marital Intimacy of Spouses Directly Influences the Rehabilitation Motivation of Hospitalized Stroke Survivors

Spousal support is likely to influence the rehabilitation motivation of stroke survivors who require long-term rehabilitation. This study was conducted to examine the reciprocal effects of the depressive symptoms and marital intimacy of stroke survivors and their spouses, and identify the factors that influence the rehabilitation motivation of stroke survivors. For this cross-sectional descriptive study, 72 stroke survivor-spouse couples were recruited from four rehabilitation hospitals in South Korea in 2017. The collected data were analyzed using path analyses with SPSS 20.0 and the R package. There were significant differences in the actor effects of stroke survivors' and spouses' depressive symptoms on the marital intimacy of the survivors and their spouses. The perceived marital intimacy of spouses was significantly associated with the rehabilitation motivation of stroke survivors. In order to enhance their rehabilitation motivation, it is necessary to periodically assess the depressive symptoms and perceived marital intimacy of their spouses.

Identifying subgroups: Part 2: Trajectories of change over time

Methods to identify multiple trajectories of change over time are of great interest in nursing and in related health research. Latent growth mixture modeling is a data-centered analytic strategy that allows us to study questions about distinct trajectories of change in key measures or outcomes of interest. In this article, a worked example of latent growth mixture modeling is presented to help expose researchers to the use and appeal of this analytic strategy.

Neighborhood Socioeconomic Status and Trajectories of Physical Health-Related Quality of Life Among Stroke Survivors

Background and Purpose- Stroke is the leading cause of serious, long-term disability in the United States, and the number of stroke survivors is projected to rise. Physical functioning status may be compromised in survivors living in low socioeconomic status environments in comparison to higher socioeconomic status environments. Higher socioeconomic status environments may include benefits in the built environment such as sidewalks, accessible transit, or low traffic volume. Investigation is needed to understand the effects of the socioenvironmental context on trajectories of stroke survivors' physical health-related quality of life (PH-QOL) over time. Methods- Participants from the REGARDS (REasons for Geographic and Racial Differences in Stroke) study enrolled in the ancillary Caring for Adults Recovering from the Effects of Stroke project completed the SF-12 around 6 to 12, 18, 27, and 36 months poststroke. Measures of area-level income, wealth, education, and employment at the census tract level were combined to represent participants' neighborhood socioeconomic status. Linear mixed models were used to predict trajectories of PH-QOL over time, controlling for individual characteristics. Results- The average trajectory of PH-QOL was flat over time. However, women and younger stroke survivors had better trajectories over time than men and older stroke survivors. Higher neighborhood socioeconomic status was significantly associated with better PH-QOL across all time points (β=1.73; 95% CI, 0.17-3.30), after controlling for demographic variables and severity of stroke. Conclusions- Our findings demonstrate that neighborhood socioeconomic status, sex, and age are associated with the poststroke recovery process. The results of this study suggest the importance of evaluating the environment surrounding stroke survivors when they return to their home communities. Future research should identify specific features of the environment within different socioeconomic status neighborhoods to better understand how they contribute to PH-QOL among stroke survivors.

Measures used to assess impact of providing care among informal caregivers of persons with stroke, spinal cord injury, or amputation: a systematic review

PURPOSE

(1) To identify measures used to evaluate the impact of caregiving among caregivers of persons with stroke, spinal cord injury, and amputation; and (2) to systematically evaluate their clinimetric properties reported in validation studies.

MATERIALS AND METHODS

Two separate systematic reviews (Embase, PsycINFO, CINAHL, Pubmed/Medline) were conducted. COSMIN guidelines were used to assess clinimetric properties and methodological quality of studies.

RESULTS

(1) 154 studies published between 2008 and May 2019 were included, in which 48 measures were used, mostly describing negative impact. Thirty measures were used only once and not further described. (2) In general, structural validity, internal consistency, and hypothesis testing were often investigated. Reliability, cross-cultural and criterion validity to a lesser extent, and scale development and content validity were rarely described. Tests of measurement error and responsiveness were exceptional. Most supporting evidence was found for the Zarit Burden Interview Short Form, Caregiver Burden Scale and Positive Aspects of Caregiving Questionnaire.

CONCLUSIONS

There is a wide variety of impact of caregiving measures. The present study provided a detailed overview of what is known about clinimetric characteristics of 18 different measures repeatedly used in research. The overview provides clinicians a guidance of appropriate measure selection.
