Determining quality of life in stroke survivors

General and Specific Quality of Life Course of Individuals with Different Levels of Stroke Severity: A One-Year Prospective Longitudinal Study

OBJECTIVES

To compare the course of generic and specific health-related quality of life (HRQOL) of individuals with stroke, and its physical, mental, and social domains, at three, six, and 12 months after hospital discharge, considering the levels of stroke severity.

METHODS

This is a longitudinal study, in stroke individuals, assessed during hospital admission by the National Institutes of Health Stroke Scale (NIHSS), and divided into mild (NIHSS ≤3) or moderate/severe (NIHSS ≥4) disease. At three, six, and 12 months after hospital discharge, the individuals were assessed for generic (Short Form Health Survey-36: total score and physical and mental domains) and specific (Stroke Specific Quality of Life Scale: total score and social domain) HRQOL. A 2 × 2 repeated measures analysis of variance (ANOVA) with post-hoc was applied.

RESULTS

146, 122, and 103 individuals were assessed at three, six and 12 months, respectively HRQOL courses showed different behaviors according to stroke severity (3.37≤F ≤ 4.62; 0.010≤p ≤ .036). Individuals with mild stroke showed significant changes in the physical domain, with a reduction between three and six months, and an increase between six and 12. Moderate/severe individuals showed a significant increase in all HRQOL variables between three and six months, and a maintenance of values for almost all variables, except for physical domain, which improved significantly between three and six months, and got significantly worse between six and 12.

CONCLUSIONS

HRQOL during the first year after stroke showed distinct trajectories, being stroke severity an important factor in identifying stroke subjects at risk of HRQOL decline.

CLINICAL IMPLICATIONS

These results demonstrate the importance of considering not only the phase of the stroke, the severity, and the general and specific HRQOL, but also the physical, social, and mainly the mental domain, which has long been neglected, when assessing this population.

A literature review of outcome and treatment options after acquired brain injury: Suggestions for adult offenders using knowledge from the general population

BACKGROUND

Acquired brain injury (ABI) is a major health problem, often with negative effects on behaviour and mental health as well as cognition. Prevalence of ABI is exceptionally high among offenders and increases their re-offending risk. Information on risk factors for ABI and its outcomes among offenders that could guide effective treatment for them is, nevertheless, scarce and dispersed. However, there is a more substantial literature about the general population that could inform work with brain-injured offenders, especially when selecting for samples or subgroups with similar relevant characteristics, such as lower socio-economic status (SES), pre-injury lower tested intelligence score (<85) and pre-injury mental health problems.

AIMS

To explore brain injury data from non-offender samples of otherwise similar socio-economic and mental health and ability characteristics to offenders then, first, to describe their untreated outcomes and, secondly, outcomes after frequently used interventions in these circumstances, noting factors associated with their effectiveness.

METHOD

Three databases were systematically searched for the years 2010-2022; first, using terms for brain injury or damage and cognitive (dys)function, mental health or quality of life. Second, in a separate search, we used these terms and terms for interventions and rehabilitation. In the second review, studies were selected for clear, distinguishable data on age, sex, SES and lifestyle factors to facilitate inferences for offenders. A narrative analytical approach was adopted for both reviews.

RESULTS

Samples with characteristics that are typical in offender groups, including lower SES, lower pre-injury intelligence quotient (<85), prior cognitive impairments and prior mental health problems, had poorer cognitive and behavioural outcomes following ABI than those without such additional problems, together with lower treatment adherence. With respect to treatment, adequate motivation and self-awareness were associated with better cognitive and behavioural outcomes than when these were low or absent, regardless of the outcome measured.

CONCLUSIONS

More complex pre-injury mental health problems and social disadvantages typical of offenders are associated with poorer post-brain injury recovery. This paper adds to practical knowledge by bringing together work that follows specific outcome trajectories. Overall, succesful ABI-interventions in the general population that aim at pre-injury difficulties comparable to those seen among offenders, show that personalising injury-specific treatments and taking account of these difficulties, maximised positive outcomes.

Acute clinical outcomes predict both generic and specific health-related quality of life six and 12 months after stroke: A one-year prospective study developed in a middle-income country

OBJECTIVE

To identify acute predictors of generic and specific health-related quality of life (HRQoL) six and 12 months after stroke in individuals from a middle-income country.

MATERIAL AND METHODS

This was a prospective study. The dependent outcomes assessed during six and 12 months after stroke included both generic and specific HRQoL (Short Form Health Survey-36 [SF-36] and stroke-specific quality of life [SSQOL]). The predictors were age, sex, education level, length of hospital stay, current living arrangement, stroke severity, functional independence, and motor impairment.

RESULTS

122 (59.9±14 years) and 103 (59.8±14.71 years) individuals were evaluated six and 12 months after stroke, respectively. Functional independence and sex were significant acute predictors of both generic and specific HRQoL. Functional independence was the strongest predictor (0.149≤R2≤0.262; 20.01≤F≤43.96, p<0.001), except for generic HRQoL at 12 months, where sex was the strongest predictor (R2=0.14; F=17.97, p<0.001).

CONCLUSION

Generic and specific HRQoL in chronic individuals six and 12 months after stroke, from a middle-income country, can be predicted based on functional independence, the strongest predictor, assessed in the acute phase, except for generic HRQoL at 12 months. Functional independence can be modified by rehabilitation strategies and thus should be considered for HRQoL prognoses at chronic phase.

Associations between pre-stroke physical activity levels and health-related quality of life 3 months after stroke: A registry-based study (part of PAPSIGOT)

BACKGROUND

Whether pre-stroke physical activity is associated with health-related quality of life after stroke has been sparsely investigated.

AIMS

To explore associations between pre-stroke physical activity and health-related quality of life 3 months after stroke onset.

METHODS

A consecutively collected cohort study with data from registries. Included were adult patients with first stroke in the period 2014-2018 who were hospitalized at any one of the three stroke units in Gothenburg, Sweden. Pre-stroke physical activity was assessed with the Saltin-Grimby Physical Activity Level Scale (SGPALS) after hospital admission for acute stroke. Health-related quality of life was assessed with the EuroQoL 5 Dimensions 5 Level Version (EQ-5D-5L) 3 months after stroke. Data were analyzed with the Kruskal-Wallis test and binary logistic regression.

RESULTS

Data were included from 2044 patients; 91% had ischemic stroke, 46% were female, and mean age was 73 years, with mild stroke severity median National Institute of Health Stroke Scale (NIHSS) of 2. Patients who were pre-stroke physically active reported better overall health-related quality of life by the EQ-5D-5L index value, all the domains in EQ-5D-5L, and the EuroQoL-Visual Analogue Scale (EQ-VAS) compared with pre-stroke physically inactive patients (all p < 0.001). Better health-related quality of life 3 months after stroke was associated with pre-stroke light and moderate physical activity: adjusted odds ratio (95% confidence interval), 1.9 (1.5-2.3) and 2.3 (1.5-3.4), respectively.

CONCLUSION

Pre-stroke physical activity is associated with better health-related quality of life 3 months after stroke. For the domains of mobility, self-care, and pain/discomfort, physical activity with higher intensity is even more beneficial.

Uncovering the social determinants of brain injury rehabilitation

Social determinants of health (SDH), such as social isolation and loneliness, are often more frequently experienced in brain injury survivors. The paper explores the personal experiences of loneliness among brain injury survivors during lockdown to negate health inequalities and improve rehabilitation for this population in the future. Twenty-four brain injury survivors participated in semi-structured interviews and questionnaires relating to loneliness, resilience and wellbeing. Three themes (the experience of loneliness, loneliness during the pandemic and loneliness after the pandemic) explored survivors' experiences of loneliness generally post-brain injury, but also chronicle how these feelings developed in lockdown and survivors' feelings regarding society returning to 'normal'. Future interventions should focus on reframing survivors' beliefs regarding societal expectations and minimise the pressure they experience to keep up with their peers physically and emotionally. Additionally, we recommend creating accessible peer support options for all brain injury survivors as an important step for alleviating loneliness.

Biofeedback interventions for short term upper limb function following stroke: A systematic review with meta-analysis

BACKGROUND

Biofeedback has been used by rehabilitation professionals in the treatment of poststroke function impairments.

PURPOSE

Investigate the efficacy of any type of biofeedback intervention for the treatment of upper limb function in individuals following stroke.

STUDY DESIGN

Systematic review of literature with meta-analysis.

METHODS

Literature searches were conducted using MESH terms and text words in PubMed, Lilacs, Scielo, Scopus, PEDro, and Web of Science databases. The main outcome was improvement in upper limb's motor function and motor function in activities of daily living. We calculated the Mean Difference and Standardized Mean Difference for the assessment scales reported as primary outcome. The methodological quality of included studies was assessed using PEDro scale. The overall quality of the evidence was assessed using GRADE system.

RESULTS

From 1360 articles identified, 16 were included in the review (09 in the meta-analysis). Three forest plots of hemiparesis and one of hemiplegia showed that biofeedback therapy associated with conventional therapy has a greater improvement in participants upper limb motor function when compared to isolated conventional therapy. Two forest plots of hemiparesis and one of hemiplegia showed no superiority in participants improvement for biofeedback associated with conventional therapy when compared to isolated conventional therapy.

CONCLUSION

Biofeedback therapy associated with conventional therapy showed a small clinical effect when associated to conventional therapy and very low quality of evidence. Although further research with higher quality evidence is needed.

Health-related quality of life and its correlates among individuals with stroke during the COVID-19 pandemic

Strict safety procedures including lockdowns were adopted during the Corona virus (COVID-19) pandemic worldwide which might have influenced mental and physical health in affected communities. This study aimed to investigate the level of Health-related quality of life (HRQoL) and its correlates among individuals with stroke in Jordan during the COVID-19 pandemic. This was a cross-sectional study with a self-administered questionnaire, which included demographics, 12-item Short Form (SF-12) health survey, Depression Anxiety Stress Scale (DASS 21), and The Stroke Impact Scale 16 (SIS-16). Descriptive analyses were used to summarize study data. Factors significantly correlated with HRQoL were determined using Pearson correlation. A total of 97 individuals successfully completed the study with a mean age of 57.9 years (±57.9). The level of HRQoL (measured by SF-12) was significantly and negatively associated with mental health symptoms (depression, anxiety, and stress) and the stroke recovery subscale of the SIS-16. Furthermore, participants' HRQoL level was significantly and positively associated with participants' age, stroke chronicity, receiving rehabilitation, and amount of help asked from caregivers. Jordanians with stroke demonstrated a relatively low level of HRQoL and high levels of mental health symptoms during the COVID-19 pandemic. Healthcare administrators should carefully consider individuals with stroke HRQoL and its correlates while planning for future crises.

Use of the International Classification of Functioning, Disability and Health (ICF) to expand and standardize the assessment of quality-of-life following a stroke: proposal for the use of codes and qualifiers

PURPOSE

Propose a way of coding and qualifying HRQoL following a stroke using the codes and qualifiers of the International Classification of Functioning, Disability and Health (ICF).

METHODS

An observational, cross-sectional study was conducted involving 51 individuals with hemiparesis resulting from a stroke. ICF codes related to the Stroke Specific Quality of Life (SS-QOL) scale were listed and subsequently classified using the generic ICF qualifiers, which range from .0 - no impairment to .4 - complete impairment. A simple mathematic calculation was proposed to convert the SS-QOL scores into ICF qualifiers.

RESULTS

The use of the ICF qualifiers revealed that the individuals exhibited a moderate level (.2) of quality of life, with mild impairment (.1) regarding upper limb function, language, self-care, and vision as well as severe impairment (.3) regarding social relations.

CONCLUSIONS

The proposal presented in this study allowed qualifying 43 ICF codes related to quality of life after a stroke in a simple, standardized manner, enabling the identification of different levels of impairment on each of the domains of the SS-QOL scale. This coding standardizes the evaluation, facilitates communication between healthcare providers, and systematizes the collection of data and information on health.Implications for rehabilitationProposal for qualifying concepts related to body functions, activity & participation, and environmental factors in a simple, standardized manner.The proposed mathematic calculation is simple and easy to understand, which minimizes the occurrence of errors.Possibility to identify different levels of impairment in each of the domains of the Stroke Specific Quality of Life scale, facilitating the establishment of individualized, longitudinal care.The ICF codes standardize the evaluation, facilitate communication between healthcare providers, and systematize the collection of data and information on health and functioning.

Adherence to Post-Stroke Pharmacotherapy: Scale Validation and Correlates among a Sample of Stroke Survivors

Background and Objectives: Adherence to post-stroke pharmacotherapy has been less studied compared with other cardiovascular diseases, and previous research in this context utilized generic tools without cross-validating for stroke specific factors and patient characteristics. This study aimed to validate the Lebanese Medication Adherence Scale (LMAS-14) among stroke survivors to assess adherence to post-stroke pharmacotherapy. It also aimed to determine the socioeconomic, clinical characteristics, and health related quality of life correlates of medication adherence among stroke survivors. Materials and Methods: This was a cross-sectional study that included stroke survivors from districts throughout Lebanon. A well-structured questionnaire consisting of three parts was developed and utilized to collect data. The first part included questions about the sociodemographic and socioeconomic characteristics. The second part included questions about medical history, current clinical characteristics of the patients, and use of medications. The third part included validated scales to assess stroke outcomes, daily performance and activities, and quality of life. Results: A total of 172 stroke survivors were included. The LMAS-14 structure was validated over a solution of three factors, with a Kaiser−Meyer−Olkin (KMO) measure of sampling adequacy = 0.836 and a significant Bartlett’s test of sphericity (p < 0.001). Severe difficulty in obtaining medications within the current Lebanese economic crisis was significantly associated with lower medication adherence (Beta = −8.473, p = 0.001). Lower medication adherence was also associated with poor stroke prognosis (Beta = −3.264, p = 0.027), higher number of used medications (Beta = −0.610, p = 0.034), and longer duration of stroke diagnosis (Beta = −4.292, p = 0.002). Conclusions: The LMAS−14 is a valid and reliable tool to assess medication adherence in stroke practice and research. Severe difficulty in obtaining medications due to unpredictable availability and shortage of supplies is associated with lower medication adherence, and thus places stroke survivors at higher risk of complications and morality. Additional measures and urgent action by stroke care providers and public health stakeholders are necessary to ensure adequate post-stroke management and outcomes.

The Burden and Quality of life of Caregivers of Stroke Survivors with Cognitive Impairment in Selected Healthcare Facilities in Anambra State, Nigeria

Objective:

To determine the burden and quality of life of caregivers of stroke survivors with cognitive impairment in selected healthcare facilities in Anambra State, Nigeria.

Methods:

This was a cross-sectional survey using the World Health Organization QOL-BREF and Caregiver Strain Index (CSI) as instruments. Descriptive statistics of frequency, percentage counts, mean and standard deviation were used to summarize the socio-demographics. Spearman’s ranked order correlation; Mann–Whitney U test assessed the correlation and gender and age difference in QoL and caregiver’s burden. Alpha level was set at 0.05.

Results:

Physical health domain of QOL was slightly moderate (53.29 ± 15.19), psychological health was low (46.33 ± 16.96), social relationship was slightly moderate (51.16 ± 0.31), environmental health was slightly moderate (51.22 ± 15.88), the burden of caregivers was high (6.35 ± 1.29).

Conclusion:

The quality of life of the caregivers of stroke survivors with cognitive impairment was moderate, and the caregivers’ stress was high in the sample of the population studied.

Responsiveness of the Spanish Version of Newcastle Stroke-Specific Quality of Life Measure (NEWSQOL)

OBJECTIVE

To evaluate the responsiveness of the Spanish version of the Newcastle Stroke-specific Quality of Life measure (NEWSQOL) to assess quality of life in Spanish people after suffering a stroke.

DESIGN

A prospective observational study was conducted to assess the responsiveness of the Spanish version of NEWSQOL. The sample contained 128 patients who filled in the questionnaires before and after a physical therapy intervention. The responsiveness was assessed with p-values using the effect size (ES) and the standardized response means (SRMs) of the change. Besides, two other external criteria were used to distinguish patients who improved with the treatment from those who remained stable. This classification was based on one functional independence measure (the Barthel Index) and one disability measure (the modified Rankin Scale).

RESULTS

There was a statistically significant correlation (Spearman's coefficient = p < 0.01) between the domains of the Spanish version of NEWSQOL in relation to the Barthel Index and the modified Rankin Scale. All domains showed between marked-to-mild change responsiveness except sleep and relationships; mobility (ES 0.66 and SRM 0.92) and activities of daily living (ES 0.75 and SRM 0.87) were markedly responsive; communication (ES 0.38 and SRM 0.61) was moderately responsive; and pain, vision, cognition, feelings, emotions and fatigue were mildly responsive (ES 0.21-0.41 and SRM 0.23-0.44).

CONCLUSION

The Spanish version of NEWSQOL shows between marked and mild responsiveness to measure the perception of QoL in post-stroke patients. Therefore, its use can be suitable for evaluation studies, clinical trials and clinical practice.

Health-related quality of life profiles and their dimension-specific associated factors among Malaysian stroke survivors: a cross sectional study

Background

Apart from maximizing functional abilities and independence after stroke, improving overall health-related quality of life (HRQoL) should also become part of the stroke treatment and rehabilitation process goals. This study aimed to assess the HRQoL profiles and explore the dimension-specific associated factors of HRQoL among stroke survivors.

Methods

This was a cross-sectional study of stroke survivors attending post-stroke care clinics in three public hospitals in the states of Pahang and Terengganu, Malaysia. The HRQoL was assessed by EuroQol-5 dimension-5 levels. Data on socio-demographic, clinical profiles, malnutrition risk, and physical activity level were collected through an interviewer-administered survey. Descriptive analyses for HRQoL profiles and multiple logistic regression analyses for its associated factors were performed. Crude and adjusted odds ratios were reported.

Results

A total of 366 stroke survivors were recruited with a mean age of 59 ± 11 years. The most -commonly reported health problems were mobility (85%), followed by usual activities (82%), pain/discomfort (63%), anxiety/depression (51%) and self-care (41%). The mean of the EQ visual analogue scale and the median of the EQ5D summary index was reported at 60.3 ± 14.2 and 0.67 ± 0.37, respectively. Malnutrition risk (mobility, usual activities, and self-care), wheelchair users (self-care and usual activities), speech impairment (usual activities and pain/discomfort), number of stroke episodes (self-care and pain/discomfort), body mass index, physical activity level and types of strokes (usual activities), age and use of a proxy (anxiety/depression), working and smoking status (mobility), were factors associated with either single or multiple dimensions of HRQoL.

Conclusion

Routine malnutrition screening, tailored program for speech therapy, prevention of recurrent stroke, and physical activity promotion should be addressed and further reinforced in current rehabilitation interventions to improve the HRQoL among stroke survivors in Malaysia.

Self-reported quality of life following stroke: a systematic review of instruments with a focus on their psychometric properties

PURPOSE

To evaluate the psychometric properties of common health-related quality-of-life instruments used post stroke and provide recommendations for research and clinical use with this diagnostic group.

METHODS

A systematic review of the psychometric properties of the five most commonly used quality-of-life measurement tools (EQ-5D, SF-36, SF-6D, AQoL, SS-QOL) was conducted. Electronic searches were performed in MEDLINE, CINAHL, and EMBASE on November 27th 2019. Two authors screened papers against the inclusion criteria and where consensus was not reached, a third author was consulted. Included papers were appraised using the COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN) checklist and findings synthesized to make recommendations.

RESULTS

A total of n = 50,908 papers were screened and n = 45 papers reporting on 40 separate evaluations of psychometric properties met inclusion criteria (EQ-5D = 19, SF-36 = 16, SF-6D = 4, AQoL = 2, SS-QOL = 4). Studies reported varied psychometric quality of instruments, and results show that psychometric properties of quality-of-life instruments for the stroke population have not been well established. The strongest evidence was identified for the use of the EQ-5D as a quality-of-life assessment for adult stroke survivors.

CONCLUSIONS

This systematic evaluation of the psychometric properties of self-reported quality-of-life instruments used with adults after stroke suggests that validity across tools should not be assumed. Clinicians and researchers alike may use findings to help identify the most valid and reliable measurement instrument for understanding the impact of stroke on patient-reported quality of life.

A prediction model of health-related quality of life in young adult patients with stroke

AIMS AND OBJECTIVES

This study aimed to establish and test a predictive model for explaining the health-related quality of life of young adult patients with stroke.

BACKGROUND

Individual characteristics, biological and physiological variables, social support, emotional and cognitive symptoms, physical function disability and general health perception may be interrelated and may directly or indirectly affect the health-related quality of life of young adult patients with stroke.

DESIGN

A cross-sectional study.

METHODS

237 young outpatients with stroke were recruited and surveyed. Data collection used a structured questionnaire from July-November 2018. The collected data were analysed using SPSS version 25.0^® and AMOS 23.0. This study is based on STROBE guidelines.

RESULTS

The hypothetical model's fit indices were adequate. Stroke severity, social support, fear of stroke recurrence, physical function disability and general health perceptions directly affected the health-related quality of life. Additionally, stroke severity, depression and fear of stroke recurrence also indirectly affected it. These variables explained 60.3% of the variance in this quality.

CONCLUSIONS

Variables such as severity of stroke, depression, fear of stroke recurrence, social support, physical function disability and general health perception were found to be related to the HRQoL of young adult patients with stroke.

RELEVANCE TO CLINICAL PRACTICE

A variety of physical, psychological, functional and social factors related to health-related quality of life should be systematically monitored. Furthermore, nurses need to develop and apply detailed nursing interventions that take into account all these variables.

Health-Related Quality of Life and Psychological Features in Post-Stroke Patients with Chronic Pain: A Cross-Sectional Study in the Neuro-Rehabilitation Context of Care

This study aims at exploring disability, health-related quality of life (HrQoL), psychological distress, and psychological features in post-stroke patients with chronic pain. An observational cross-sectional study involving 50 post-stroke patients (25 with chronic pain and 25 without pain) was conducted. The primary outcome was the self-reported level of disability and HrQoL which were both assessed through the Stroke Impact Scale 3.0. Both psychological distress and specific psychological features (i.e., self-efficacy, coping strategies, psychological flexibility, perceived social support) were examined. Post-stroke patients with chronic pain reported statistically significant higher levels of disability and worse HrQoL, higher psychological distress and inflexibility, as well as a lower level of self-efficacy and problem-oriented coping strategies than patients without pain (p < 0.001). Finally, correlation analysis in the group of stroke survivors with pain showed that higher levels of disability were significantly related to higher psychological distress. This study confirms the negative influence of chronic pain on disability and HrQoL in post-stroke patients and presents preliminary insights on the association between chronic pain, disability, HrQoL, psychosocial distress, and the patient’s approach in dealing with personal difficulties and emotions. These findings carry further implications for multidisciplinary management of post-stroke patients with chronic pain.

Socio-ecological perspective on factors influencing acute recovery of younger stroke survivors: A mixed methods study

AIMS

Stroke is affecting an increasing number of young and middle-aged adults. Given the substantial diversion from anticipated life trajectories that younger stroke survivors experience as a result of their stroke deficits, their health-related quality of life (HRQOL) is likely to be negatively impacted during the immediate post-acute recovery period. The aim of this study was to generate a comprehensive understanding of the influences on HRQOL and acute recovery during the first three months following stroke for younger adults using a socio-ecological perspective.

DESIGN

Longitudinal, convergent mixed methods design.

METHODS

HRQOL survey data, assessed using the Patient Generated Index (N = 31), and qualitative interview data about survivors' recovery experiences (N = 20) were collected. Simple linear regression and effect size results were integrated with themes and sub-themes identified from conventional content analysis using joint data displays.

RESULTS

Depression and fatigue negatively affected recovery at the individual level. At the family and societal level, family functioning, social support including being married, having insurance, working, adequate income and being unemployed post-stroke all positively impacted recovery. Qualitative findings revealed determination, coping, and accessing healthcare to positively affect recovery though a meta-inference could not be drawn as no quantitative data addressed these concepts.

CONCLUSION

A variety of factors intersecting across socio-ecological levels were perceived by young stroke survivors to influence acute recovery experiences and outcomes.

IMPACT

This study identified individual-, family- and societal-level factors in younger adults' environments that may affect the acute stroke recovery experience. Findings underscore the need for research and clinical approaches that consider environmental factors at multiple levels of influence when supporting stroke recovery for younger adults.

Patient Reported Outcomes Measurements Information System in Stroke Patients in Full and Shortened Format

Introduction: The modified Rankin Scale (mRS) after 90 days documents outcome in stroke patients, but focusses only on activities of daily living. Here we studied stroke outcome beyond these activities by the Dutch-Flemish version of the Patient Reported Outcomes Measurement Information System (PROMIS) questionnaire. Patients and Methods: We documented the mRS at day 90 in stroke patients who filled out a questionnaire on pain intensity and seven PROMIS domains: physical function, ability to participate in social roles, anxiety, fatigue, depression, sleep disturbance, pain interference. In a subgroup of patients this questionnaire was reduced to one overall question per PROMIS domain. We correlated these findings with the mRS. Results: We received 102 questionnaires and identified physical function as the most affected PROMIS domain. The strongest correlation with mRS was found for the health domains of physical function (ρs = 0.70, p < 0.001) and ability to participate in social roles (ρs = 0.61, p < 0.001). The other domains with substantial proportions of patients with worse scores compared to the general population (19-44%) correlated weakly with the mRS. We identified a strong correlation between the single question per health domain and the overall score per PROMIS domain. Discussion and Conclusion: PROMIS better reflects the overall health status of stroke patients beyond functional outcome as measured by the mRS. Simplification of the questionnaire with a single question per PROMIS domain could potentially replace the full questionnaire, but needs further validation.

Determinants of Health Status After Stroke: A Cohort Study with Repeated Measurements

Background

Knowledge about the long-term course of health following stroke is sparse and relies mainly on studies with short follow-up or few measurements per patient. We aimed to describe the course and analyze the determinants of the course of physical and mental health status after stroke with repeated measurements in a large population-based cohort of first time Danish stroke patients.

Methods

We followed 2,414 first time stroke patients admitted to any hospital in the Central Denmark Region, Denmark, between October 1, 2008 and January 1, 2012, with five questionnaires over a 2 years period. Self-rated health was assessed by the SF-12 instrument. Information on possible clinical and patient-related determinants of self-rated health was obtained from questionnaires and national registers. The scores were analyzed at five selected fixed time-points and as well as longitudinally with mixed models.

Results

The SF-12 mental component summary score (MCS) increased with 0.89 points/year (95% CI=0.6–1.2), while the increase in the physically component summary score (PCS) did not reach statistical significance (0.13/year; 95% CI=−0.2–0.5). The most pronounced changes were seen in the Vitality and Role Physical SF-12 subscales, which both increased by 2.1 points/year. No statistically significant changes over time were found in the Physical Functioning and Bodily Pain subscales. Variables associated with increasing self-rated mental health (MCS) were no comorbidity, older age, male gender, and mild stroke severity. Variables associated with increasing ratings of physical health (PCS) were mild stroke severity, no comorbidity, higher educational level, and younger age. The negative impact of age increased significantly with time during the follow-up period for physical as well as mental health, while the effects of the other variables were stable over time. The results were similar in the two analytical approaches.

Conclusion

In a large, geographically well-defined population of first time stroke patients, the majority of SF-12 sub-scales and the mental component score improved slightly over time. Small improvements in self-rated mental health may be observed during the first 2 years after the stroke. Stroke is a disease with long-term consequences on a wide range of health aspects. Level as well as course differ between sub-groups, and treatment of comorbidity may be an important target with respect to rehabilitation.

Patient-reported, health-related, quality of life after stroke thrombectomy in clinical practice

OBJECTIVE

To determine patient-reported health-related quality of life (HRQOL) after stroke thrombectomy in clinical practice and to identify predictors of better HRQOL by analyzing data of 504 consecutive patients treated in a large university stroke center.

METHODS

All patients with stroke treated by thrombectomy (June 2015-October 2018) were prospectively enrolled in this observational study. At 90 days, functional outcome was assessed by the modified Rankin Scale (mRS) and patient-reported HRQOL was assessed by the EuroQol Group 5-Dimension (EQ-5D) self-report questionnaire, consisting of 5 health domains. The EQ-5D utility index (EQ-5D-I) score (-0.594 to 1.00, with higher values indicating better HRQOL) was calculated. Linear regression analysis was applied to identify predictors of better HRQOL (higher EQ-5D-I score).

RESULTS

Of 504 patients (median age 76 years, 51.8% female), the mean EQ-5D-I score was 0.39 (SD 0.44). The proportion of stroke survivors who reported complaints in the different domains decreased from 66% in Usual Activities to 57% in Mobility, 50.4% in Self-Care, 41.7% in Pain/Discomfort, and 40.8% Anxiety/Depression. Lower age, lower prestroke mRS score, lower baseline NIH Stroke Scale score, higher Alberta Stroke Program Early CT Score, concomitant thrombolysis therapy, and a successful recanalization were independent predictors of better HRQOL.

CONCLUSIONS

Patient-reported HRQOL provides a more comprehensive assessment of stroke outcome than the mRS score. Health domains involving motor function most frequently showed complaints in HRQOL after stroke thrombectomy, while a large proportion of patients did not report any complaints across the different health domains. Predictors of better HRQOL closely match the predictors of better functional outcome measured by the mRS in other thrombectomy studies.

An iPad application-based intervention for improving post-stroke depression symptoms in a convalescent rehabilitation ward: A pilot randomized controlled clinical trial protocol

BACKGROUND

Post-stroke depression (PSD) is a neuropsychiatric sequela that causes serious adverse effects on the prognosis of stroke patients. Our developed iPad application is a very innovative approach designed to improve participants' depressive symptoms by presenting positive words stimuli in a video. Although this application has fewer side effects than existing pharmacological and non-pharmacological interventions and is likely less burdensome for patients and caregivers, its efficacy for PSD has not been investigated. Here we present a pilot randomized controlled trial (RCT) protocol to investigate the therapeutic potential of this application intervention for PSD patients.

METHODS

This study is designed as a 5-week, single-center, open-label, parallel-group, pilot RCT. Thirty-two patients with PSD will be randomly assigned to a combination of the iPad application and usual rehabilitation or usual rehabilitation alone (1:1 allocation ratio). The iPad application intervention lasts 3 min a day, and the usual rehabilitation lasts 3 h a day. The primary outcome is the change from baseline in The Center for Epidemiologic Studies Depression Scale score at the end of the 5-week intervention.

DISCUSSION

This pilot RCT is the first study to investigate the potential of iPad application interventions to reduce depressive symptoms in PSD patients. This pilot RCT determines whether this is a viable and effective intervention and informs the design for a full-scale trial. If our hypothesis is correct, this trial can provide evidence to augment the standard practice of iPad application interventions to improve depressive symptoms in patients with PSD.

Identifying Instruments to Assess Care Quality for Individuals With Custom Ankle Foot Orthoses: A Scoping Review

OBJECTIVES

We conducted 2 complementary scoping reviews to identify instruments that assess the experience and outcomes of custom ankle-foot orthosis (AFO) care in individuals with neurologic and traumatic conditions and to determine to what extent they might be psychometrically sound for AFO users. A stakeholder advisory committee considered to what extent the identified and psychometrically sound instruments might be feasible for use in developing quality measures for custom AFO users.

DATA SOURCES

Both scoping reviews were conducted using PubMed, the Cumulative Index to Nursing and Allied Health Literature, Embase, and Cochrane Systematic Reviews. The following were used for the first scoping review only: Cochrane Central Register of Controlled Trials and the Physiotherapy Evidence Database.

STUDY SELECTION

The initial scoping review yielded 79 articles with 82 instruments, 16 of which were used in 4 or more studies. The second scoping review yielded 57 articles reporting psychometric properties.

DATA EXTRACTION

Psychometric properties for populations who use AFOs were summarized for 15 of the 16 instruments. The advisory committee eliminated 2 insrtruments, noted overlap between 4 instruments in terms of the constructs measured, and suggested 6 potential contemporary substitutes.

DATA SYNTHESIS

Most instruments assessed activity (specifically mobility) and pertained to the National Quality Forum domain of "Health-Related Quality of Life." The 10-meter walk test, 6-minute walk test, Berg Balance Scale, Timed Up and Go, and Rivermead Mobility Index were reported to have adequate reliability and validity, and were considered feasible for administration in a clinical setting.

CONCLUSIONS

Complementary scoping reviews demonstrated that some instruments with reasonable psychometric properties are available that are feasible to use in developing quality measures for custom AFO care. However, experience of care instruments suitable for this population were not identified but are needed for a comprehensive evaluation of care quality for AFO users.

Validation of the Spanish Version of Newcastle Stroke-Specific Quality of Life Measure (NEWSQOL)

BACKGROUND

Stroke causes a wide variety of clinical manifestations that may have a negative impact on quality of life. Therefore, it is very important to use specific instruments for measuring quality of life in individuals who suffered a stroke. The aim of this study was to develop a psychometrically validated Spanish version of the Newcastle stroke-specific quality of life measure (NEWSQOL).

METHODS

A psychometric validation of the Spanish version of the NEWSQOL questionnaire was carried out in 159 patients. The reliability (intraclass correlation coefficient and Cronbach's alpha coefficient), validity (factorial analysis and Spearman's coefficient), feasibility (response rate), and the ceiling and floor effects were calculated.

RESULTS

Internal consistency showed that Cronbach's alpha coefficient was 0.93. The test-retest reliability was high or excellent for all domains (range 0.71-0.97 p < 0.001). The response rate of the questionnaire was 100% and the average administration time was 20.5 (±7.2) min. No ceiling effect was detected and two domains (pain and vision) may have a significant potential for floor effect. Construct validity showed that all the variables are important enough to keep them all in the questionnaire. Concerning convergent construct validity, a high correlation was found with the Nottingham Health Profile, the Barthel Index, and the Modified Rankin Scale.

CONCLUSION

The Spanish version of the NEWSQOL questionnaire is reliable, valid, and feasible to evaluate quality of life in the Spanish population.

Stroke-Specific Quality of Life one-year post-stroke in two Scandinavian country-regions with different organisation of rehabilitation services: a prospective study

Purpose: To compare stroke-specific health related quality of life in two country-regions with organisational differences in subacute rehabilitation services, and to reveal whether organisational factors or individual factors impact outcome.Materials and methods: A prospective multicentre study with one-year follow-up of 369 first-ever stroke survivors with ischaemic or haemorrhagic stroke, recruited from stroke units in North Norway (n = 208) and Central Denmark (n = 161). The 12-domain Stroke-Specific Quality of Life scale was the primary outcome-measure.Results: The Norwegian participants were older than the Danish (M_age= 69.8 vs. 66.7 years, respectively), had higher initial stroke severity, and longer stroke unit stays. Both cohorts reported more problems with cognitive, social, and emotional functioning compared to physical functioning. Two scale components were revealed. Between-country differences in the cognitive-social-mental component showed slightly better function in the Norwegian participants. Depression, anxiety, pre-stroke dependency, initial stroke severity, and older age were substantially associated to scale scores.Conclusions: Successful improvements in one-year functioning in both country-regions may result from optimising long-term rehabilitation services to address cognitive, emotional, and social functioning. Stroke-Specific Quality of Life one-year post-stroke could be explained by individual factors, such as pre-stroke dependency and mental health, rather than differences in the organisation of subacute rehabilitation services.IMPLICATIONS FOR REHABILITATIONThe stroke-specific health related quality of life (SS-QOL) assessment tool captures multidimensional effects of a stroke from the perspective of the patient, which is clinically important information for the rehabilitation services.The cognitive-social-mental component and the physical health component, indicate specific functional problems which may vary across and within countries and regions with different organisation of rehabilitation services.For persons with mild to moderate stroke, longer-term functional improvements may be better optimised if the rehabilitation services particularly address cognitive, emotional, and social functioning.

Pregnancy, postpartum and parity: Resilience and vulnerability in brain health and disease

Risk and resilience in brain health and disease can be influenced by a variety of factors. While there is a growing appreciation to consider sex as one of these factors, far less attention has been paid to sex-specific variables that may differentially impact females such as pregnancy and reproductive history. In this review, we focus on nervous system disorders which show a female bias and for which there is data from basic research and clinical studies pointing to modification in disease risk and progression during pregnancy, postpartum and/or as a result of parity: multiple sclerosis (MS), depression, stroke, and Alzheimer's disease (AD). In doing so, we join others (Shors, 2016; Galea et al., 2018a) in aiming to illustrate the importance of looking beyond sex in neuroscience research.

Determinant of Quality of Life in Patients with Chronic Cerebral Infarct

This study investigated how physical and cognitive function and psychological factors affected the health-related quality of life (HRQoL, hereafter HQ) of stroke patients in South Korea. The study enrolled 32 right-handed subjects with chronic cerebral infarction with disability and preserved cognitive function (Mini-Mental State Examination ≥ 20). Physical disability was assessed using the modified Rankin Scale (mRS) and Korean modified Barthel Index (KMBI). Quality of life was measured using the World Health Organization Quality of Life-Abbreviated form (WHOQOL-BREF, hereafter WB) and the 36-Item Short-form Health Survey (SF-36) in face-to-face interviews. Psychological distress was investigated using the Beck Depression Inventory Scale-II. The associations of each domain of WB and SF-36 were investigated using Pearson correlation analyses. Physical disability was negatively correlated with HQ in the SF-36. The physical function and bodily pain scales of the SF-36 were negatively correlated with physical disability. The general health domain of the SF-36 was negatively correlated with psychological scores. Emotional status was associated with physical health, social relationships, and general health in HQ. In summary, the severity of physical disability was associated with the patient's general and physical health and body pain. These findings suggest the importance of psychological, cognitive, and physiological interventions for improving the quality of life of patients after cerebral infarction.

Walking speed as a predictor of community mobility and quality of life after stroke

Background: Community mobility (CM) is considered a part of community reintegration that enhances Quality of Life (QoL). Achieving an appropriate gait speed is essential in attaining an independent outdoor ambulation and satisfactory CM. Objective: The aim of this study was to identify whether gait speed is a predictor of CM and QoL in patients with stroke following a multimodal rehabilitation program (MRP). Methods: This was a baseline control trial with 6-months follow-up in an outpatient rehabilitation setting at a university hospital. Twenty-six stroke survivors completed the MRP (24 sessions, 2 days/wk, 1 hr/session). The MRP consisted of aerobic exercise, task-oriented exercises, balance exercises and stretching. Participants also performed an ambulation program at home. Outcome variables were: walking speed (10-m walking test) and QoL (physical and psychosocial domains of Euroquol and Sickness Impact Profile). Results: At the end of the intervention, comfortable and fast walking speed increased by an average of 0.16 (SD 0.21) (*p < .05) and 0.40 (SD 0.51) (**p < .001) m/s, respectively. After the intervention, all participants achieved independent outdoor ambulation with an increase of 34.14 of walking minutes/day in the community and a decrease of sitting time of 95.45 minutes/day. Regarding QoL there were increased mean scores on the physical and psychosocial dimensions of Euroquol and the Sickness Impact Profile, respectively (**p < .001). Conclusions: The results suggest that improved walking speed after the MRP is associated with CM and higher scores in QoL. These findings support the need to implement rehabilitation programs to promote increased speed.

Can the health related quality of life measure QOLIBRI- overall scale (OS) be of use after stroke? A validation study

BACKGROUND

Brief measures of health-related quality of life (HRQOL) that assess both patient-reported functioning and well-being after stroke are scarce. The objective of this study was to examine reliability and validity of one of these measures, the patient-reported Quality of Life after Brain Injury-Overall Scale (QOLIBRI-OS), in patients after stroke.

METHODS

Stroke survivors were examined prospectively using survey methods. Core survey data (n = 125) and retest data (n = 36) were obtained at 3 and 12 months, respectively. Item properties (distribution, floor and ceiling effects), psychometric properties (reliability and model fit), and validity (correlations with established measures of anxiety, depression and HRQOL) of the QOLIBRI-OS were examined.

RESULTS

Missing responses on the questionnaire were low (0.5%). All items were positively skewed. No floor effects were present, whereas five out of six items showed ceiling effects. The summary QOLIBRI-OS score exhibited no floor or ceiling effects, and had excellent internal consistency (Cronbach's α =0.93). All item-total correlations were high (0.73-0.88). The test-retest reliability of single items varied from 0.74 to 0.91 and was 0.93 for the overall score. The confirmatory factor analysis yielded an excellent fit for a five-item version and provided tentative support for the original six-item version. The convergent validity correlations were in the hypothesized directions, thus supporting the construct validity.

CONCLUSIONS

The brief QOLIBRI-OS is a valid and reliable brief health-related outcome measure that is appropriate for screening HRQOL in patients after stroke.

The most affected health domains after ischemic stroke

OBJECTIVES

(1) Examine 8 patient-reported domains of health across levels of disability compared to the US general population; and (2) identify factors associated with domain scores in patients with ischemic stroke.

METHODS

Observational cohort study of 1,195 patients in a cerebrovascular clinic from February 17, 2015, to January 27, 2017, who completed Neuro-QoL (Quality of Life in Neurological Disorders) executive function or the following PROMIS (Patient-Reported Outcomes Measurement Information System) scales as part of routine care: physical function, satisfaction with social roles, fatigue, anxiety, depression, pain interference, and sleep disturbance.

RESULTS

Mean age was 62 (±15) years, and 81% were white. Median modified Rankin Scale (mRS) score at the clinic visit was 1 (interquartile range 0-2). Percentage of patients with scores meaningfully worse than the general population ranged from 28% (sleep disturbance) to 63% (physical function). Scores were worse in patients with higher mRS levels, although correlation between scores and mRS level varied (sleep disturbance r = 0.16 to physical function r = 0.52). Most affected domains were physical function (T score = 58.8), satisfaction with social roles (T score = 55.4), and executive function (T score = 53.4). Disability, lower income, and female sex were associated with worse scores in multiple domains. Age was associated with worse physical function but lower anxiety, depression, and sleep disturbance.

CONCLUSIONS

Patients with ischemic stroke reported symptoms in multiple domains that increase to variable degrees at higher levels of disability. Physical function, satisfaction with social roles, and executive function were most affected. This information improves our understanding of the well-being of patients with ischemic stroke and brings attention to the importance of social roles and executive function for stroke survivors.

Effectiveness of a multimodal exercise rehabilitation program on walking capacity and functionality after a stroke

The aim of this study was to determine the effectiveness of a 12-week multimodal exercise rehabilitation program on walking speed, walking ability and activities of daily living (ADLs) among people who had suffered a stroke. Thirty-one stroke survivors who had completed a conventional rehabilitation program voluntarily participated in the study. Twenty-six participants completed the multimodal exercise rehabilitation program (2 days/wk, 1 hr/session). Physical outcome measures were: walking speed (10-m walking test), walking ability (6-min walking test and functional ambulation classification) and ADLs (Barthel Index). The program consisted on: aerobic exercise; task oriented exercises; balance and postural tonic activities; and stretching. Participants also followed a program of progressive ambulation at home. They were evaluated at baseline, postintervention and at the end of a 6-month follow-up period. After the intervention there were significant improvements in all outcomes measures that were maintained 6 months later. Comfortable and fast walking speed increased an average of 0.16 and 0.40 m/sec, respectively. The walking distance in the 6-min walking test increased an average of 59.8 m. At the end of the intervention, participants had achieved independent ambulation both indoors and outdoors. In ADLs, 40% were independent at baseline vs. 64% at the end of the intervention. Our study demonstrates that a multimodal exercise rehabilitation program adapted to stroke survivors has benefits on walking speed, walking ability and independence in ADLs.

Factors influencing pre-stroke and post-stroke quality of life among stroke survivors in a lower middle-income country

Quality of life (QOL) reflects the individual's perception of the position within living contexts. This study was done to describe pre- and post-stroke QOLs of stroke survivors. A prospective longitudinal study was done among stroke survivors admitted to 13 hospitals in the western province of Sri Lanka. The calculated sample size was 260. The pre-stroke and post-discharge one-month QOL was gathered using short form-36 (SF-36) QOL tool. SF-36 includes questions on eight domains: general health, physical functioning, pain, role limitation due to physical problems, social functioning, vitality, role limitations due to emotional problems, and mental health. Univariate analysis was followed by determining the independent risk factors through multivariate analysis. The response rate was 81%. The disability was measured by the modified Rankin scale which ranges from 0 (no symptoms) to 6 (fatal outcome). The median (IQR) disability score was 4 (3 to 5). The post-discharge QOL scores were significantly lower than pre-stroke values (p < 0.05). With a higher pre-stroke QOL, younger age was significantly associated in six domains and higher income and better health infrastructure in two domains (p < 0.05). Six factors were determined to be independent risk factors for lower post-discharge QOL scores of SF-36: younger age (for general health and role limitation-physical domains), female gender (for physical functioning and pain domains), lower health infrastructure (for general health, vitality, and mental health domains), lower education (for pain domain), higher disability (for general health, physical functioning, vitality, social functioning, and mental health domains), and hypercholesterolemia (for role limitation-emotional domain). Stroke survivors have not regained their pre-stroke QOL at 1 month following the hospital discharge irrespective of income level and pre-stroke QOL. Higher pre- and post-stroke QOLs are associated with better statuses of social determinants of health.

Discordance in Utility Measurement in Persons with Neurological Conditions: A Comparison of the SF-6D and the HUI3

OBJECTIVES

To examine the extent of disagreement in estimated utility between the six-dimensional health state short form (SF-6D) and the Health Utilities Index-Mark 3 (HUI3) in Canadians with neurological conditions and how discordance varied by participant and neurological condition attributes.

METHODS

The study analyzed cross-sectional survey data from the Living with and Managing the Impact of a Neurological Condition Study. Self-reported data were collected on the burden and impact of neurological conditions on participants' everyday lives. Disagreement was examined by comparing utility distributions, paired t tests of the means, Spearman ρ correlations, intraclass correlations, and Bland-Altman plots. Associations between participant and neurological condition attributes and utility differences were assessed using multiple regression models.

RESULTS

Disagreement between the SF-6D and the HUI3 was substantial, with a mean utility difference of 0.15 (95% confidence interval 0.13-0.17). An intraclass correlation coefficient of 0.41 suggests only marginal agreement. The Bland-Altman plot and regression analysis showed systematic variation in utility difference associated with level of utility. Depending on the level of utility, utility differences between the SF-6D and the HUI3 shift in magnitude and direction. The pattern of disagreement did not vary substantially by participant or neurological condition characteristics.

CONCLUSIONS

The SF-6D and the HUI3 provide inconsistent evaluations of utility in persons with neurological conditions. The magnitude and direction of differences in estimated utility are strongly associated with level of utility. Depending on the health status of the sample, the SF-6D and the HUI3 could provide widely contradictory utility estimates. A concern is that utility scores, and hence potential evaluations and health care decisions, may vary simply according to the choice of instrument.

Increased work and social engagement is associated with increased stroke specific quality of life in stroke survivors at 3 months and 12 months post-stroke: a longitudinal study of an Australian stroke cohort

BACKGROUND

There is a relative lack of longitudinal studies investigating stroke-specific outcomes and quality of life (QOL). This study aimed to identify which factors (level of disability, cognitive functioning, depressive symptoms, physical activity, and work and social engagement) were independently associated with each stroke-specific domain of QOL, adjusting for age and gender, at 3 months and 12 months post-stroke in an Australian cohort.

METHOD

Survivors of ischemic stroke were recruited from 18 sites of the STroke imAging pRevention and Treatment (START) longitudinal cohort study. Survivors were assessed at 3 months (n = 185) and 12 months (n = 170) post-stroke using the Stroke Impact Scale (SIS), modified Rankin Scale (mRS), Montreal Cognitive Assessment (MoCA), Montgomery-Asberg Depression Rating Scale, Rapid Assessment of Physical Activity, and Work and Social Adjustment Scale (WSAS).

RESULTS

WSAS was independently associated with the SIS domains of: Physical Composite function; Participation; and Perceived Recovery at 3 months and 12 months and SIS domain of Emotion at 12 months post-stroke. The presence of depressive symptoms was independently associated with the SIS domains of: Memory and Thinking; and Emotion at 3 months. At 12 months post-stroke, mRS was independently associated with SIS domain of Physical Composite function and MoCA with SIS domain of Communication.

CONCLUSION

Engaging in work and social activities is an important factor associated with stroke-specific domains of QOL over time. It is recommended that services focus on improving work and social engagement given their importance related to QOL in the first year of recovery post-stroke. Identifying and treating those with depressive symptoms may enhance QOL in the early months post-stroke.

Health-related quality of life in stroke patients questionnaire, short version (HRQOLISP-40): validation for its use in Colombia

Background

The health-related quality of life in stroke patients (HRQOLISP-40, short version) survey was developed in Nigeria and constitutes a 40-item, multidimensional, self-administrated questionnaire. We assessed the validity and reliability of the HRQOLISP-40 Spanish version for stroke patients in Colombia.

Methods

The analysis included factor analysis, confirmatory factor analysis, Rasch analysis, convergent validity, internal consistency (261 stroke patients), test-retest reliability (73 patients assessed at two different times) and sensitivity to change (46 patients assessed before and after a rehabilitation intervention).

Results

We found an 8-domain structure. None of the items had a significant impact on the global alpha value in order to be removed. Lin’s concordance correlation coefficient indicated test-retest reliability (Rho IC: 0.76 to 0.95), suggesting an adequate stability of the instrument. Regarding sensitivity to change differences, they were only significant in the psychological and eco-social domains (p <0.05). When comparing SF-36 with HRQOLISP-40, all the correlation coefficients values were significantly different from zero, except those related to vitality. The highest scores were found in the physical and physical functioning domains, with a value of 0.722.

Conclusions

The HRQOLISP-40 scale is valid and reliable for assessing patients’ quality of life after a stroke. Validating quality of life assessment instruments is necessary in order to improve the effectiveness of rehabilitation programs for Colombian stroke patients.

Lesão Encefálica Adquirida: impacto na atividade laboral de sujeitos em idade produtiva e de seus familiares

Resumo Este estudo correlacionou o impacto da Lesão Encefálica Adquirida (LEA) na atividade laboral de sujeitos em idade produtiva à sua Qualidade de Vida (QV) e de seus familiares/cuidadores. Pesquisa quali-quantitativa. Para a análise dos dados qualitativos realizou-se Análise de Conteúdo e os quantitativos foram analisados descritivamente. Foram entrevistados 48 sujeitos com LEA e 27 familiares/cuidadores. A correlação da Classificação Internacional de Funcionalidade, Incapacidade e Saúde - WHOQOL-BREF (52,1% homens; média de idade 48,7 anos, no momento da lesão; nível escolar baixo; 18,7% doméstica) revelou que as Funções Mentais comprometidas pela LEA interferiram nos quatro domínios da QV; Funções do Coração e Pressão Sanguínea acometeram o domínio Social; a lesão Cerebral interferiu nos domínios Psicológico e Ambiental. Quanto aos familiares/cuidadores (77,7% mulheres; 96,3% informais; média de idade 52,6 anos; e nível escolar baixo), observaram-se alterações na rotina de trabalho e na estrutura familiar (85,2%). O surgimento de uma LEA desorganiza o sujeito lesionado e sua família, afetando a QV em todos os seus domínios, especialmente nos físicos, psicológicos e ambientais do primeiro e os domínios físicos e ambientais de familiares/cuidadores.

Examining the relationship between fatigue and cognition after stroke: A systematic review

Many stroke survivors experience fatigue, which is associated with a variety of factors including cognitive impairment. A few studies have examined the relationship between fatigue and cognition and have obtained conflicting results. The aim of the current study was to review the literature on the relationship between fatigue and cognition post-stroke. The following databases were searched: EMBASE (1980-February, 2014), PsycInfo (1806-February, 2014), CINAHL (1937-February, 2014), MEDLINE (1946-February, 2014), Ethos (1600-February, 2014) and DART (1999-February, 2014). Reference lists of relevant papers were screened and the citation indices of the included papers were searched using Web of Science. Studies were considered if they were on adult stroke patients and assessed the following: fatigue with quantitative measurements (≥ 3 response categories), cognition using objective measurements, and the relationship between fatigue and cognition. Overall, 413 papers were identified, of which 11 were included. Four studies found significant correlations between fatigue and memory, attention, speed of information processing and reading speed (r = -.36 to .46) whereas seven studies did not. Most studies had limitations; quality scores ranged from 9 to 14 on the Critical Appraisal Skills Programme Checklists. There was insufficient evidence to support or refute a relationship between fatigue and cognition post-stroke. More robust studies are needed.

The effect of cognitive appraisal in middle-aged women stroke survivors and the psychological health of their caregivers: a follow-up study

AIMS AND OBJECTIVES

This study identified the factors that affect health-related quality of life at one and six months post-stroke in women who have undergone a mild stroke and that affect their informal caregivers' psychological health status.

BACKGROUND

Middle-aged women perform the main care roles in a family. When they suffer a stroke, it upsets the equilibrium of their family life.

DESIGN

This is a longitudinal design.

METHODS

This prospective follow-up study recruited 41 middle-aged women stroke survivors (mean age = 54.95, SD = 9.63) and their informal caregivers (mean age = 41.56, SD = 15.93). The Short-Form Health Survey (SF-36) was used to assess stroke survivor's health-related quality of life, and the Chinese Health Questionnaire was used to measure the level of depression of the stroke survivor's informal caregiver. Data were analysed through descriptive statistics, Wilcoxon signed-rank tests and the generalised estimating equation approach for modelling repeatedly measures.

RESULTS

All stroke survivors showed significant improvement in the physical component summary of the health-related quality of life at one and six months after stroke, but there was no significant difference in the mental component summary. In addition, there was no significant difference in the health of the informal caregivers of the women over time. Generalised estimating equation analysis showed that the most important determinant of mental component summary of health-related quality of life among women stroke survivors was cognitive appraisal. The informal caregivers' most important determinants of health status, as measured by level of depression, were their sense of coherence, burden and patients' mental component summary of the health-related quality of life.

CONCLUSION

This study highlights the impact of cognitive appraisal in determining health-related quality of life of women stroke survivors and how it affects their caregivers' mental health.

RELEVANCE TO CLINICAL PRACTICE

The findings of this study may contribute to home care nurses' understanding the importance of the psychosocial impact of the stroke for the survivor and their ability to help the surviving women to promote the confidence needed for self-care, which will contribute to their quality of life and affect their caregivers' health.

Quality of life in stroke survivor-caregiver dyads: a new conceptual framework and longitudinal study protocol

AIM

To describe a new conceptual framework and the research protocol of a study designed to examine the quality of life in stroke survivor-caregiver dyads.

BACKGROUND

Stroke has a significant impact on the patient-caregiver dyad. Few studies have been guided by a specific conceptual framework which considers the interactions among pre-existing situations prior to stroke, the new situation caused by the stroke and the moderating effects of environmental and caregiver-related variables.

DESIGN

Longitudinal study.

METHODS

A sample of stroke survivor-caregiver dyads will be enrolled at patient discharge from rehabilitation hospitals and will be surveyed every 3 months for 1-year. Hypotheses generated from the conceptual framework will test predictors, mediators and moderators of stroke survivor and caregiver quality of life from the pre-existing situation prior to the stroke, the new situation mediation poststroke and situation moderators. The study is supported by a grant from the Centre of Excellence for Nursing Scholarship, Rome, December 2013.

DISCUSSION

This study seeks to identify variables in the pre-existing situation prior to the stroke (e.g. living condition), the new situation mediation poststroke (e.g. type of stroke and caregiver burden) as well as situation moderators (e.g. social support) that influence stroke survivor-caregiver dyad's quality of life across the stroke trajectory. Also, the study will inform clinical practice and research by identifying variables that are potentially modifiable and therefore amenable to intervention. The proposed framework will also be helpful for future research focused on stroke survivor-caregiver dyads.

Stroke service: how can we improve and measure outcomes? Consensus summary from a global stroke forum

The success of acute stroke treatment is first and foremost time-dependent, and the need for improvement in acute stroke management is demonstrated by the fact that only a minority of patients gain access to treatment - in particular, intravenous recombinant tissue plasminogen activator (IV tPA) - within the necessary time window. Standards of acute stroke care vary widely both regionally and nationally; consequently, various healthcare organizations have undertaken initiatives to measure and improve quality of care. To date, most quality measures have been process-based, focusing primarily on metrics of patient care in the acute hospital-based setting (e.g., time to recombinant tPA administration). Therefore, there remains a need for metrics designed to assess how improvements in process translate into patient outcomes. A global forum was convened to share best practice and provide consensus recommendations on core metrics for measuring improvements in access to care and patient outcomes. Recommendations for core metrics of patient outcomes include hospital-based outcomes (e.g., neurological status at 24 h, ambulatory status at discharge) and post-discharge outcomes (e.g., modified Rankin Scale score at 30 and/or 90 days). Recommendations for best practice relating to aspects of people, process, and technology involved in the stroke treatment pathway that may help provide improvements in these core outcome measures are also outlined.

Predictors of poststroke health-related quality of life in Nigerian stroke survivors: a 1-year follow-up study

This study aims to identify the predictors in the different aspects of the health-related quality of life (HRQoL) and to measure the changes of functional status over time in a cohort of Nigerian stroke survivors. A prospective observational study was conducted in three hospitals of Kano state of Nigeria where stroke survivors receive rehabilitation. The linguistic-validated Hausa versions of the stroke impact scale 3.0, modified Rankin scale, Barthel index and Beck depression inventory scales were used. Paired samples t-test was used to calculate the amount of changes that occur over time and the forward stepwise linear regression model was used to identify the predictors. A total of 233 stroke survivors were surveyed at 6 months, and 93% (217/233) were followed at 1 year after stroke. Functional disabilities were significantly reduced during the recovery phase. Motor impairment, disability, and level of depression were independent predictors of HRQoL in the multivariate regression analysis. The involvement of family members as caregivers is the key factor for those survivors with improved functional status. Thus, to enhance the quality of poststroke life, it is proposed that a holistic stroke rehabilitation service and an active involvement of family members are established at every possible level.

The Stroke Impact Scale: validation in a UK setting and development of a SIS short form and SIS index

BACKGROUND AND PURPOSE

The Stroke Impact Scale (SIS) covers 8 dimensions and a composite disability score. This study evaluates the SIS in the UK context, and develops a single index and an 8-item short form.

METHODS

Patients with a diagnosis of stroke were recruited through general practices in London and the North-West of England. Patients completed the SIS and the EQ-5D.

RESULTS

Internal consistency of the SIS dimensions and the disability score ranged from α 0.86 to 0.95. Complete data were available on 73 questionnaires (48.34%). Factor analysis suggested the 8 domains could be aggregated into a single index. A short-form SIS (SF-SIS) index was created by summing 1 item per dimension. Selected items were those that most highly correlated with their respective domain score (ρ ranged from 0.77-0.94, P<0.001). The SF-SIS index scores were highly correlated with those gained from the parent form (ρ=0.98; P<0.001). The correlation of the SIS index and SF-SIS index with the EQ-5D was identical (ρ=0.83; P<0.001). The disability score, whether scored from the dimensions of the SIS, or relevant items on the SF-SIS, were highly correlated (ρ=0.97; P<0.001).

CONCLUSIONS

The SIS covers aspects of health, which are of importance to stroke patients, and the dimensions were found to have high levels of internal consistency in the UK context. The amount of incomplete data suggests that the length of the questionnaire may present a substantial patient burden. In comparison to the parent form the SF-SIS can accurately provide the disability score and overall index score with considerable brevity.

Epidemiology and disease burden of ischemic stroke in Taiwan

BACKGROUND

The incidence and prevalence of ischemic stroke (IS) are increasing in Asian countries. We conducted this retrospective database research to investigate epidemiology and disease burden of IS in Taiwan.

METHODS

We identified cases from the National Health Insurance Research Database during period from 2000 to 2005 to calculate prevalence and mortality. We analyzed the relationship between disease burden and gender in Taiwan during the period from 2000 to 2005 using Dismod II.

RESULTS

From study period, stroke mortality increased from 50 to 2300 per 100 000 among individuals aged 50-90 years, with a higher prevalence among females than males. The highest prevalence was observed among men aged 80-84 years, but prevalence among women was highest in patients aged >85 years. The burden of stroke during the period per 1000 population was estimated as follows: the sum of the years of life lost as a result of premature mortality of 55-80 years, years lost as a result of disability of 11-19 years, and disability-adjusted life years (DALYs) of 70-80 years. Most of the DALYs of stroke occurred among those aged 65-69 years. The DALY value was higher among women than among men before 2005; there was no clear trend in 2005.

CONCLUSIONS

Stroke is a significant health concern in Taiwan. The associated disease burden was found to increase each year, especially among individuals aged 65-69 years. Overall, the DALY value increased from 2000 to 2005, which suggests that the associated disease burden will continue to increase over time.
