The impact of ethnicity on stroke care access and patient outcomes: a New Zealand nationwide observational study

Comparing acute hospital outcomes for people with post-stroke aphasia who do and do not require an interpreter

BACKGROUND

People with communication differences are known to have poorer hospital outcomes than their peers. However, the combined impact of aphasia and cultural/linguistic differences on care and outcomes after stroke remains unknown.

OBJECTIVES

To investigate the association between cultural/linguistic differences, defined as those requiring an interpreter, and the provision of acute evidence-based stroke care and in-hospital outcomes for people with aphasia.

METHODS

Cross-sectional, observational data collected in the Stroke Foundation National Audit of Acute Services (2017, 2019, 2021) were used. Multivariable regression models compared evidence-based care and in-hospital outcomes (e.g., length of stay) by interpreter status. Models were adjusted for sex, hospital location, stroke type and severity, with clustering by hospital.

RESULTS

Among 3122 people with aphasia (median age 78, 49% female) from 126 hospitals, 193 (6%) required an interpreter (median age 78, 55% female). Compared to people with aphasia not requiring an interpreter, those requiring an interpreter had similar care access but less often had their mood assessed (OR 0.50, 95% CI 0.32, 0.76), were more likely to have physiotherapy assessments (96% vs 90% p = 0.011) and carer training (OR 4.83, 95% CI 1.70, 13.70), had a 2 day longer median length of stay (8 days vs 6 days, p = 0.003), and were less likely to be independent on discharge (OR 0.54, 95% CI 0.33, 0.89).

CONCLUSIONS

Some differences exist in the management and outcomes for people with post-stroke aphasia who require an interpreter. Further research to explore their needs and the practical issues underpinning their clinical care pathways is required.

Psychosocial well-being after stroke in Aotearoa New Zealand: a qualitative metasynthesis

PURPOSE

Psychosocial well-being is key to living well after stroke, but often significantly affected by stroke. Existing understandings consider well-being comes from positive mood, social relationships, self-identity and engagement in meaningful activities. However, these understandings are socioculturally located and not necessarily universally applicable. This qualitative metasynthesis examined how people experience well-being after a stroke in Aotearoa New Zealand.

MATERIAL AND METHODS

This metasynthesis was underpinned by He Awa Whiria (Braided Rivers), a model which prompts researchers to uniquely engage with Māori and non-Māori knowledges. A systematic search identified 18 articles exploring experiences of people with stroke in Aotearoa. Articles were analysed using reflexive thematic analysis.

RESULTS

We constructed three themes which reflect experiences of well-being: connection within a constellation of relationships, being grounded in one's enduring and evolving identities, and being at-home in the present whilst (re)visioning the future.

CONCLUSION

Well-being is multi-faceted. In Aotearoa, it is inherently collective while also deeply personal. Well-being is collectively achieved through connections with self, others, community and culture, and embedded within personal and collective temporal worlds. These rich understandings of well-being can open up different considerations of how well-being is supported by and within stroke services.

Addressing disparities in the global epidemiology of stroke

Stroke is the second leading cause of death and the third leading cause of disability worldwide. Though the burden of stroke worldwide seems to have declined in the past three decades, much of this effect reflects decreases in high-income countries (HICs). By contrast, the burden of stroke has grown rapidly in low-income and middle-income countries (LMICs), where epidemiological, socioeconomic and demographic shifts have increased the incidence of stroke and other non-communicable diseases. Furthermore, even in HICs, disparities in stroke epidemiology exist along racial, ethnic, socioeconomic and geographical lines. In this Review, we highlight the under-acknowledged disparities in the burden of stroke. We emphasize the shifting global landscape of stroke risk factors, critical gaps in stroke service delivery, and the need for a more granular analysis of the burden of stroke within and between LMICs and HICs to guide context-appropriate capacity-building. Finally, we review strategies for addressing key inequalities in stroke epidemiology, including improvements in epidemiological surveillance and context-specific research efforts in under-resourced regions, development of the global workforce of stroke care providers, expansion of access to preventive and treatment services through mobile and telehealth platforms, and scaling up of evidence-based strategies and policies that target local, national, regional and global stroke disparities.

Incidence, clinical features, and outcomes of posterior circulation ischemic stroke: insights from a large multiethnic stroke database

Background

Posterior cerebral circulation ischemic stroke (PCS) comprises up to 25% of all strokes. It is characterized by variable presentation, leading to misdiagnosis and morbidity and mortality. We aim to describe PCS in large multiethnic cohorts.

Methods

A retrospective review of a large national stroke database from its inception on the 1st of January 2014 till 31 December 2020. Incidence per 100,000 adult population/year, demographics, clinical features, stroke location, and outcomes were retrieved. We divided the cohort into patients from MENA (Middle East and North Africa) and others.

Results

In total, 1,571 patients were identified. The incidence of PCS was observed to be rising and ranged from 6.3 to 13.2/100,000 adult population over the study period. Men were 82.4% of the total. The mean age was 54.9 ± 12.7 years (median 54 years, IQR 46, 63). MENA patients comprised 616 (39.2%) while others were 954 (60.7%); of these, the majority (80.5%) were from South Asia. Vascular risk factors were prevalent with 1,230 (78.3%) having hypertension, 970 (61.7%) with diabetes, and 872 (55.5%) having dyslipidemia. Weakness (944, 58.8%), dizziness (801, 50.5%), and slurred speech (584, 36.2%) were the most commonly presenting symptoms. The mean National Institute of Health Stroke Score (NIHSS) score was 3.8 ± 4.6 (median 3, IQR 1, 5). The overall most frequent stroke location was the distal location (568, 36.2%). The non-MENA cohort was younger, less vascularly burdened, and had more frequent proximal stroke location (p < 0.05). Dependency or death at discharge was seen in 39.5% and was associated with increasing age, and proximal and multilocation involvement; while at 90 days it was 27.4% and was associated with age, male sex, and having a MENA nationality (p < 0.05).

Conclusion

In a multiethnic cohort of posterior circulation stroke patients from the MENA region and South Asia, we noted a rising incidence over time, high prevalence of vascular risk factors, and poor outcomes in older men from the MENA region. We also uncovered considerable disparities between the MENA and non-MENA groups in stroke location and outcome. These disparities are crucial factors to consider when tailoring individualized patient care plans. Further research is needed to thoroughly investigate the underlying reasons for these variations.

Preference-based measures of health-related quality of life in Indigenous people: a systematic review

PURPOSE

In many countries, there are calls to address health inequalities experienced by Indigenous people. Preference-based measures (PBMs) provide a measurement of health-related quality of life and can support resource allocation decisions. This review aimed to identify, summarize, and appraise the literature reporting the use and performance of PBMs with Indigenous people.

METHODS

Eleven major databases were searched from inception to August 31, 2022. Records in English that (1) assessed any measurement property of PBMs, (2) directly elicited health preferences, (3) reported the development or translation of PBMs for Indigenous people, or (4) measured health-related quality of life (HRQL) using PBMs were included. Ethically engaged research with Indigenous people was considered as an element of methodological quality. Data was synthesized descriptively (PROSPERO ID: CRD42020205239).

RESULTS

Of 3139 records identified, 81 were eligible, describing psychometric evaluation (n = 4), preference elicitation (n = 4), development (n = 4), translation (n = 2), and HRQL measurement (n = 71). 31 reported ethically engaged research. Reports originated primarily from Australia (n = 38), New Zealand (n = 20), USA (n = 9) and Canada (n = 6). Nearly all (n = 73) reported indirect, multi-attribute PBMs, the most common of which was the EQ-5D (n = 50).

CONCLUSION

A large number of recent publications from diverse disciplines report the use of PBMs with Indigenous people, despite little evidence on measurement properties in these populations. Understanding the measurement properties of PBMs with Indigenous people is important to better understand how these measures might, or might not, be used in policy and resource decisions affecting Indigenous people.

Biographical continuation: recovery of stroke survivors and their family caregivers in Taiwan

AIM

To explore the experiences pertaining to long-term care services from the perspectives of dyads of stroke survivors and their family caregivers in indigenous and non-indigenous communities.

BACKGROUND

Stroke occurrence is a life-changing event associated with quality of life for stroke survivors and their families, especially those who provide primary support. Indigenous people are more likely to experience a stroke at a younger age and have a higher likelihood of hospitalisation and death due to health disparities. Few studies have investigated family dyads or indigenous populations to understand their experiences of coping with changed body-self and to contextualise their reintegration into communities post-stroke.

METHODS

Ethnographic fieldwork over nine months in 2018-2019 with indigenous, urban-based, and non-indigenous populations, resulting in 48 observations and 24 interviews with 12 dyads in three geo-administrative communities.

FINDINGS

The post-stroke recovery trajectory is illuminated, delineating the dyads' life transitions from biographical disruption to biographical continuation. The trajectory is shaped by seven states involving four mindsets and three status passages. The four mindsets are sense of loss and worry, sense of interdependence, sense of independence, and wellbeing state. The status passages identified in this study are acceptance, alteration, and identification. A community-based and family-centred long-term care system, aligning with medical healthcare and community resources, underpinned each dyad's biographical continuation by: (1) providing rehabilitation that afforded time and space for recovery adaptation; (2) acknowledging the individuality of family caregivers and helping to alleviate their multitasking; and (3) reintegrating stroke survivors into their communities. Key to determining the quality of recovery for the indigenous participants was their reintegration into their native community and regaining of identity. Therefore, integrating post-stroke care into various care contexts and incorporating indigenous-specific needs into policymaking can support dyads in adapting to their communities.

Patient, carer and health worker perspectives of stroke care in New Zealand: a mixed methods survey

PURPOSE

It is important to understand how consumers (person with stroke/family member/carer) and health workers perceive stroke care services.

MATERIALS AND METHODS

Consumers and health workers from across New Zealand were surveyed on perceptions of stroke care, access barriers, and views on service centralisation. Quantitative data were summarised using descriptive statistics whilst thematic analysis was used for free-text answers.

RESULTS

Of 149 consumers and 79 health workers invited to complete a survey, 53 consumers (36.5%) and 41 health workers (51.8%) responded. Overall, 40/46 (87%) consumers rated stroke care as 'good/excellent' compared to 24/41 (58.6%) health workers. Approximately 72% of consumers preferred to transfer to a specialised hospital. We identified three major themes related to perceptions of stroke care: 1) 'variability in care by stage of treatment'; 2) 'impact of communication by health workers on care experience'; and 3) 'inadequate post-acute services for younger patients'. Four access barrier themes were identified: 1) 'geographic inequities'; 2) 'knowing what is available'; 3) 'knowledge about stroke and available services'; and 4) 'healthcare system factors'.

CONCLUSIONS

Perceptions of stroke care differed between consumers and health workers, highlighting the importance of involving both in service co-design. Improving communication, post-hospital follow-up, and geographic equity are key areas for improvement.Implications for rehabilitationProvision of detailed information on stroke recovery and available services in the community is recommended.Improvements in the delivery of post-hospital stroke care are required to optimise stroke care, with options including routine phone follow up appointments and wider development of early supported discharge services.Stroke rehabilitation services should continue to be delivered 'close to home' to allow community integration.Telehealth is a likely enabler to allow specialist urban clinicians to support non-urban clinicians, as well as increasing the availability and access of community rehabilitation.

Comparison of Stroke Care Costs in Urban and Nonurban Hospitals and Its Association With Outcomes in New Zealand: A Nationwide Economic Evaluation

BACKGROUND

Although geographical differences in treatment and outcomes after stroke have been described, we lack evidence on differences in the costs of treatment between urban and nonurban regions. Additionally, it is unclear whether greater costs in one setting are justified given the outcomes achieved. We aimed to compare costs and quality-adjusted life years in people with stroke admitted to urban and nonurban hospitals in New Zealand.

METHODS

Observational study of patients with stroke admitted to the 28 New Zealand acute stroke hospitals (10 in urban areas) recruited between May and October 2018. Data were collected up to 12 months poststroke including treatments in hospital, inpatient rehabilitation, other health service utilization, aged residential care, productivity, and health-related quality of life. Costs in New Zealand dollars were estimated from a societal perspective and assigned to the initial hospital that patients presented to. Unit prices for 2018 were obtained from government and hospital sources. Multivariable regression analyses were conducted when assessing differences between groups.

RESULTS

Of 1510 patients (median age 78 years, 48% female), 607 presented to nonurban and 903 to urban hospitals. Mean hospital costs were greater in urban than nonurban hospitals ($13 191 versus $11 635, P=0.002), as were total costs to 12 months ($22 381 versus $17 217, P<0.001) and quality-adjusted life years to 12 months (0.54 versus 0.46, P<0.001). Differences in costs and quality-adjusted life years remained between groups after adjustment. Depending on the covariates included, costs per additional quality-adjusted life year in the urban hospitals compared to the nonurban hospitals ranged from $65 038 (unadjusted) to $136 125 (covariates: age, sex, prestroke disability, stroke type, severity, and ethnicity).

CONCLUSIONS

Better outcomes following initial presentation to urban hospitals were associated with greater costs compared to nonurban hospitals. These findings may inform greater targeted expenditure in some nonurban hospitals to improve access to treatment and optimize outcomes.
