Background: Stroke registers are recommended as a key priority by the Lancet Neurology World Stroke Organization Commission for Stroke, 2023, and the African Stroke Leaders' Summit, 2022. Aims: This scoping review aims to map where stroke registers have been implemented in Sub-Saharan Africa (SSA). The article then compares and critiques the methods and definitions used and summarizes key results from the registers. The scoping review searched EMBASE, MEDLINE, and CABI Global Health databases and included all studies with a prospective longitudinal design in SSA, where adult acute stroke was the primary condition studied. Articles were screened against inclusion and exclusion criteria independently by two authors. Summary: We identified 42 unique stroke registers from 48 individual studies. The registers were located in 19 countries, with 19 from East Africa, 15 West Africa, 6 Central Africa, and 2 from Southern Africa. Cumulatively, the registers recruited 12,345 participants with stroke, the median number of participants was 183 (interquartile range (IQR): 121–312), and the range was 50–1018. Only one study was a population-based register, and 41 were hospital-based registers. Of the hospital-based registers, 29 were single site, 10 were conducted at two sites, and 2 at three sites. Twenty-three (54.7%) of the registers were located in the capital city of their respective country, and only one of the hospital-based registers was in a self-described rural area. Length of recruitment ranged from 4 months to 6 years; the median length of recruitment was 12 months. Methodology and definitions were heterogenous between the registers. Only seven (19.4%) registers referenced the WHO STEPwise approach to implementing stroke registers. Twenty-seven (64.3%) registers used the WHO definition of stroke. The mean neuroimaging rate was 84%, and ranged from 0% to 100%. Stroke severity was measured using the National Institute of Health Stroke Scale (NIHSS) in 22 (52.4%) registers, four registers used the Glasgow Coma Scale (GCS), two registers used the miniNIHSS, one used the Scandinavian Stroke Scale, one modified Rankin Scale (mRS), and 11 registers did not report a stroke severity measure. Seventeen (40.5%) registers used the mRS to measure function, six registers used Barthel Index alone, and three registers used both mRS and Barthel Index. Only two registers included a quality-of-life measure, the EQ-5D. Eight registers included a quality-of-care measure, and 26 (61.9%) registers recorded socioeconomic status or a socioeconomic status proxy, most frequently educational attainment. Conclusions: This scoping review found high heterogeneity of methods and definitions used by stroke registers, with low uptake of the WHO stepwise method of stroke surveillance. A drive to standardize methodology would improve the comparability of stroke data in SSA. The shared use of educational attainment by registers in our review may enable future meta-analyses of inequities in stroke in SSA. Incorporating health-related quality-of-life measures, such as EQ-5D, into stroke registers should be encouraged, bringing a patient perspective, and allow the estimation of quality-adjusted life years lost to stroke. Agreement on a standardized register methodology or further promotion and uptake of the WHO stepwise method is essential to produce comparable data to improve stroke prevention and care.

Background: Stroke is a leading cause of mortality and negatively affects health-related quality of life (HRQoL). HRQoL after stroke is understudied in Africa and there are no reports of quality-adjusted life years after stroke (QALYs) in African countries. We determined the impact of stroke on HRQoL after stroke in Sierra Leone. We calculated QALYs at 1 year post-stroke and determined sociodemographic and clinical variables associated with HRQoL and QALYs in this population. Methods: A prospective stroke register was established at the two-principal adult tertiary government hospitals in Freetown, Sierra Leone. Participants were followed up at 7, 90 days, and 1 year post-stroke to capture all-cause mortality and EQ-5D-3L data. QALYs were calculated at the patient level using EQ-5D-3L utility values and survival data from the register, following the area under the curve method. Utilities were based on the UK and Zimbabwe (as a sensitivity analysis) EQ-5D value sets, as there is no Sierra Leonean or West African value set. Explanatory models were developed based on previous literature to assess variables associated with HRQoL and QALYs at 1 year after stroke. To address missing values, Multiple Imputation by Chained Equations (MICE), with linear and logistic regression models for continuous and binary variables, respectively, were used. Results: EQ-5D-3L data were available for 373/460 (81.1%), 360/367 (98.1%), and 299/308 (97.1%) participants at 7, 90 days, and 1 year after stroke. For stroke survivors, median EQ-5D-3L utility increased from 0.20 (95% CI: −0.16 to 0.59) at 7 days post-stroke to 0.76 (0.47 to 1.0) at 90 days and remained stable at 1 year 0.76 (0.49 to 1.0). Mean QALYs at 1 year after stroke were 0.28 (SD: 0.35) and closely associated with stroke severity. Older age, lower educational attainment, patients with subarachnoid hemorrhage and undetermined stroke types all had lower QALYs and lower HRQoL, while being the primary breadwinner was associated with higher HRQoL. Sensitivity analysis with the Zimbabwe value set did not significantly change regression results but did influence the absolute values with Zimbabwe utility values being higher, with fewer utility values less than 0. Conclusion: We generated QALYs after stroke for the first time in an African country. QALYs were significantly lower than studies from outside Africa, partially explained by the high mortality rate in our cohort. Further research is needed to develop appropriate value sets for West African countries and to examine QALYs lost due to stroke over longer time periods. Data availability: The Stroke in Sierra Leone anonymized dataset is available on request to researchers, see data access section. [ABSTRACT FROM AUTHOR]

Background: 'High-cost' individuals with multimorbidity account for a disproportionately large share of healthcare costs and are at most risk of poor quality of care and health outcomes. Aim: To compare high-cost with lower-cost individuals with multimorbidity and assess whether these populations can be clustered based on similar disease patterns. Design and setting: A cross-sectional study based on 2019/2020 electronic medical records from adults registered to primary care practices (n = 41) in a London borough. Method: Multimorbidity is defined as having ≥2 long-term conditions (LTCs). Primary care costs reflected consultations, which were costed based on provider and consultation types. High cost was defined as the top 20% of individuals in the cost distribution. Descriptive analyses identified combinations of 32 LTCs and their contribution to costs. Latent class analysis explored clustering patterns. Results: Of 386 238 individuals, 101 498 (26%) had multimorbidity. The high-cost group (n = 20 304) incurred 53% of total costs and had 6833 unique disease combinations, about three times the diversity of the lower-cost group (n = 81 194). The trio of anxiety, chronic pain, and depression represented the highest share of costs (5%). High-cost individuals were best grouped into five clusters, but no cluster was dominated by a single LTC combination. In three of five clusters, mental health conditions were the most prevalent. Conclusion: High-cost individuals with multimorbidity have extensive heterogeneity in LTCs, with no single LTC combination dominating their primary care costs. The frequent presence of mental health conditions in this population supports the need to enhance coordination of mental and physical health care to improve outcomes and reduce costs.

Background: There is limited information on long-term outcomes after stroke in sub-Saharan Africa (SSA). Current estimates of case fatality rate (CFR) in SSA are based on small sample sizes with varying study design and report heterogeneous results. Aims: We report CFR and functional outcomes from a large, prospective, longitudinal cohort of stroke patients in Sierra Leone and describe factors associated with mortality and functional outcome. Methods: A prospective longitudinal stroke register was established at both adult tertiary government hospitals in Freetown, Sierra Leone. It recruited all patients ⩾ 18 years with stroke, using the World Health Organization definition, from May 2019 until October 2021. To reduce selection bias onto the register, all investigations were paid by the funder and outreach conducted to raise awareness of the study. Sociodemographic data, National Institute of Health Stroke Scale (NIHSS), and Barthel Index (BI) were collected on all patients on admission, at 7 days, 90 days, 1 year, and 2 years post stroke. Cox proportional hazards models were constructed to identify factors associated with all-cause mortality. A binomial logistic regression model reports odds ratio (OR) for functional independence at 1 year. Results: A total of 986 patients with stroke were included, of which 857 (87%) received neuroimaging. Follow-up rate was 82% at 1 year, missing item data were <1% for most variables. Stroke cases were equally split by sex and mean age was 58.9 (SD: 14.0) years. About 625 (63%) were ischemic, 206 (21%) primary intracerebral hemorrhage, 25 (3%) subarachnoid hemorrhage, and 130 (13%) were of undetermined stroke type. Median NIHSS was 16 (9–24). CFR at 30 days, 90 days, 1 year, and 2 years was 37%, 44%, 49%, and 53%, respectively. Factors associated with increased fatality at any timepoint were male sex (hazard ratio (HR): 1.28 (1.05–1.56)), previous stroke (HR: 1.34 (1.04–1.71)), atrial fibrillation (HR: 1.58(1.06–2.34)), subarachnoid hemorrhage (HR: 2.31 (1.40–3.81)), undetermined stroke type (HR: 3.18 (2.44–4.14)), and in-hospital complications (HR: 1.65 (1.36–1.98)). About 93% of patients were completely independent prior to their stroke, declining to 19% at 1 year after stroke. Functional improvement was most likely to occur between 7 and 90 days post stroke with 35% patients improving, and 13% improving between 90 days to 1 year. Increasing age (OR: 0.97 (0.95–0.99)), previous stroke (OR: 0.50 (0.26–0.98)), NIHSS (OR: 0.89 (0.86–0.91)), undetermined stroke type (OR: 0.18 (0.05–0.62)), and ⩾1 in-hospital complication (OR: 0.52 (0.34–0.80)) were associated with lower OR of functional independence at 1 year. Hypertension (OR: 1.98 (1.14–3.44)) and being the primary breadwinner of the household (OR: 1.59 (1.01–2.49)) were associated with functional independence at 1 year. Conclusion: Stroke affected younger people and resulted in high rates of fatality and functional impairment relative to global averages. Key clinical priorities for reducing fatality include preventing stroke-related complications through evidence-based stroke care, improved detection and management of atrial fibrillation, and increasing coverage of secondary prevention. Further research into care pathways and interventions to encourage care seeking for less severe strokes should be prioritized, including reducing the cost barrier for stroke investigations and care.

Women of reproductive age are a group of particular concern with regards to vaccine uptake, related to their unique considerations of menstruation, fertility, and pregnancy. To obtain vaccine uptake data specific to this group, we obtained vaccine surveillance data from the Office for National Statistics, linked with COVID-19 vaccination status from the National Immunisation Management Service, England, from 8 Dec 2020 to 15 Feb 2021; data from 13,128,525 such women at population-level, were clustered by age (18–29, 30–39, and 40–49 years), self-defined ethnicity (19 UK government categories), and index of multiple deprivation (IMD, geographically-defined IMD quintiles). Here we show that among women of reproductive age, older age, White ethnicity and being in the least-deprived index of multiple deprivation are each independently associated with higher vaccine uptake, for first and second doses; however, ethnicity exerts the strongest influence (and IMD the weakest). These findings should inform future vaccination public messaging and policy.Women of reproductive age may have specific concerns relating to perceived impacts on fertility and menstrual cycles that make them hesitant to receive COVID-19 vaccination. In this study, the authors explore COVID-19 vaccine uptake rates in women of reproductive age using linked data for ~13 million women in England. [ABSTRACT FROM AUTHOR]

Background: People with multimorbidity have complex healthcare needs. Some co-occurring diseases interact with each other to a larger extent than others and may have a different impact on primary care use.Aim: To assess the association between multimorbidity clusters and primary care consultations over time.Design and Setting: A retrospective longitudinal (panel) study design was used. Data comprised electronic primary care health records of 826 166 patients registered at GP practices in an ethnically diverse, urban setting in London between 2005 and 2020.Method: Primary care consultation rates were modelled using generalised estimating equations. Key controls included the total number of long-term conditions, five multimorbidity clusters, and their interaction effects, ethnic group, and polypharmacy (proxy for disease severity). Models were also calibrated by consultation type and ethnic group.Results: Individuals with multimorbidity used two to three times more primary care services than those without multimorbidity (incidence rate ratio 2.30, 95% confidence interval = 2.29 to 2.32). Patients in the alcohol dependence, substance dependence, and HIV cluster (Dependence+) had the highest rate of increase in primary care consultations as additional long-term conditions accumulated, followed by the mental health cluster (anxiety and depression). Differences by ethnic group were observed, with the largest impact in the chronic liver disease and viral hepatitis cluster for individuals of Black or Asian ethnicity.Conclusion: This study identified multimorbidity clusters with the highest primary care demand over time as additional long-term conditions developed, differentiating by consultation type and ethnicity. Targeting clinical practice to prevent multimorbidity progression for these groups may lessen future pressures on primary care demand by improving health outcomes. [ABSTRACT FROM AUTHOR]

Background: Managing multimorbidity is complex for both patients and healthcare systems. Patients with multimorbidity often use a variety of primary and secondary care services. Country-specific research exploring the healthcare utilisation and cost consequences of multimorbidity may inform future interventions and payment schemes in the UK.Aim: To assess the relationship between multimorbidity, healthcare costs, and healthcare utilisation; and to determine how this relationship varies by disease combinations and healthcare components.Design and Setting: A systematic review.Method: This systematic review followed the bidirectional citation searching to completion method. MEDLINE and grey literature were searched for UK studies since 2004. An iterative review of references and citations was completed. Authors from all articles selected were contacted and asked to check for completeness of UK evidence. The National Institutes of Health National Heart, Lung, and Blood Institute quality assessment tool was used to assess risk of bias. Data were extracted, findings synthesised, and study heterogeneity assessed; meta-analysis was conducted when possible.Results: Seventeen studies were identified: seven predicting healthcare costs and 10 healthcare utilisation. Multimorbidity was found to be associated with increased total costs, hospital costs, care transition costs, primary care use, dental care use, emergency department use, and hospitalisations. Several studies demonstrated the high cost of depression and of hospitalisation associated with multimorbidity.Conclusion: In the UK, multimorbidity increases healthcare utilisation and costs of primary, secondary, and dental care. Future research is needed to examine whether integrated care schemes offer efficiencies in healthcare provision for multimorbidity. [ABSTRACT FROM AUTHOR]

Quality of care worries and rising costs have resulted in a widespread interest in enhancing the efficiency of health care delivery. One area of increasing interest is in promoting teamwork as a way of coordinating efforts to reduce costs and improve quality, and identifying the characteristics of the work environment that support teamwork. Relational climate is a measure of the work environment that captures shared employee perceptions of teamwork, conflict resolution, and diversity acceptance. Previous research has found a positive association between relational climate and quality of care, yet its relationship with costs remains unexplored. We examined the influence of primary care relational climate on health care costs incurred by diabetic patients at the U.S. Department of Veterans Affairs between 2008 and 2012. We found that better relational climate is significantly related to lower costs. Clinics with the strongest relational climate saved $334 in outpatient costs per patient compared with facilities with the weakest score in 2010. The total outpatient cost saving if all clinics achieved the top 5% relational climate score was $20 million. Relational climate may contribute to lower costs by enhancing diabetic treatment work processes, especially in outpatient settings. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to determine which characteristics of youths with posttraumatic stress disorder (PTSD) were associated with receiving prescriptions for antidepressants, antipsychotics, or benzodiazepines.Methods: A 2011-2012 retrospective cohort of children and adolescents with a new episode of PTSD was extracted from medical and pharmacy claims from a nationally representative sample of privately insured persons. Multivariate logistic regression assessed attributes (demographic characteristics, mental and general medical comorbidities, insurance arrangements, specialty type, and geographic location) associated with utilization of antidepressants, antipsychotics, and benzodiazepines.Results: Among 7,726 youths with a new episode of PTSD in 2012, just less than 60% received psychotherapy alone, about 6% received pharmacotherapy, and about 35% received neither psychotherapy nor pharmacotherapy. Among utilizers of medications, 71.3% used antidepressants and 21.6% used antipsychotics. Youths prescribed medication tended to be older and have more general medical and mental comorbidities. Provider specialty, capitated insurance arrangements, and more comorbidities predicted being prescribed antidepressants. History of hospitalization, noncapitated insurance arrangements, nonuse of psychotherapy, and more comorbidities predicted being prescribed antipsychotics. Antidepressants and antipsychotics were more likely to be used in the South.Conclusions: Only three-fifths of youths with PTSD received first-line treatment (psychotherapy). More than one in 20 received pharmacotherapy, which appeared to be associated with the most severe and complex presentations. More than one-third of youths with PTSD received neither therapy nor medication, signaling compromised quality of care. Future research should confirm the factors associated with pharmacotherapy prescription and explore ways to increase the use of psychotherapy in primary care. [ABSTRACT FROM AUTHOR]

Current breast cancer screening guidelines promote the use of shared decision making for women younger than 50 years of age, yet their effect on mammography utilization is largely unknown. This study aimed to examine the effect of two elements of shared decision making on the use of mammogram screening: patient-perceived choice and patient–provider communication. Data were obtained from HINTS 4, a nationally representative survey of the U.S. population, administered from 2011 to 2013. Choice was measured with the question “Has a doctor ever told you that you could choose whether or not to have a mammogram?” Communication was measured using a 7-item scale (range: 7–28; higher scores denote better communication). Binary logistic regression models assessed the effect of patient choice and communication on ever having a mammogram using weighted sample data. The sample included 1,085 women younger than 50 years of age: 31% of women perceived having a choice to undergo mammography. The mean patient–provider communication score was 22.8. Those who thought they were given a choice regarding mammography were more likely to have a mammogram relative to those who did not think a choice was given by the provider. Patient–provider communication had no significant association with mammography utilization. Patient perceived choice, but not patient-provider communication, is positively associated with mammography utilization in women younger than 50 years of age. [ABSTRACT FROM PUBLISHER]

Introduction: The Children and Young People's Health Partnership (CYPHP) Evelina London Model of Care is a new approach to integrated care delivery for children and young people (CYP) with common health complaints and chronic conditions. CYPHP includes population health management (services shaped by data-driven understanding of population and individual needs, applied in this case to enable proactive case finding and tailored biopsychosocial care), specialist clinics with multidisciplinary health teams and training resources for professionals working with CYP. This complex health system strengthening programme has been implemented in South London since April 2018 and will be evaluated using a cluster randomised controlled trial with an embedded process evaluation. This protocol describes the within-trial and beyond-trial economic evaluation of CYPHP., Methods and Analysis: The economic evaluation will identify, measure and value resources and health outcome impacts of CYPHP compared with enhanced usual care from a National Health Service/Personal Social Service and a broader societal perspective. The study population includes 90 000 CYP under 16 years of age in 23 clusters (groups of general practitioner (GP) practices) to assess health service use and costs, with more detailed cost-effectiveness analysis of a targeted sample of 2138 CYP with asthma, eczema or constipation (tracer conditions). For the cost-effectiveness analysis, health outcomes will be measured using the Paediatric Quality of Life Inventory and quality-adjusted life years (QALYs) using the Child Health Utility 9 Dimensions (CHU-9D) measure. To account for changes in parental well-being, the Warwick-Edinburg Mental Well-being Scale will be integrated with QALYs in a cost-benefit analysis. The within-trial economic evaluation will be complemented by a novel long-term model that expands the analytical horizon to 10 years. Analyses will adhere to good practice guidelines and National Institute for Health and Care Excellence public health reference case., Ethics and Dissemination: The study has received ethical approval from South West-Cornwall and Plymouth Research Ethics Committee (REC Reference: 17/SW/0275). Results will be submitted for publication in peer-reviewed journals, made available in briefing papers for local decision-makers, and provided to the local community through website and public events. Findings will be generalisable to community-based models of care, especially in urban settings., Trial Registration Number: NCT03461848., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Importance: Patient-reported outcomes serving as benchmarks for recovery of pediatric burn survivors are lacking, and new approaches using longitudinal cohorts for monitoring their expected recovery based on statistical models are needed for patient management during the early years following the burn., Objective: To describe multidimensional patient-reported outcomes among pediatric burn survivors younger than 5 years to establish benchmarks using recovery curve methods., Design, Setting, and Participants: Prospective cohort study of pediatric burn survivors younger than 5 years at 12 burn centers. Age-matched nonburned reference groups were studied to define expected results in normal growth and development. The Burn Outcomes Questionnaire for children aged 0 to 5 years (BOQ0-5) was administered to parents of children who had burns and were younger than 5 years. Mixed models were used to generate 48-month recovery curves for each of the 10 BOQ0-5 domains. The study was conducted between January 1999 and December 2008., Main Outcomes and Measures: The 10 BOQ0-5 domains including play, language, fine motor skills, gross motor skills, emotional behavior, family functioning, pain/itching, appearance, satisfaction with care, and worry/concern up to 48 months after burn injury., Results: A total of 336 pediatric burn survivors younger than 5 years (mean [SD] age, 2.0 [1.2] years; 58.4% male; 60.2% white, 18.6% black, and 12.0% Hispanic) and 285 age-matched nonburned controls (mean [SD] age, 2.4 [1.3] years; 51.1% male; 67.1% white, 8.9% black, and 15.0% Hispanic) completed the study. Predicted scores improved exponentially over time for 5 of the BOQ0-5 domains (predicted scores at 1 month vs 24 months: play, 48.6 vs 52.1 [P = .03]; language, 49.2 vs 54.4 [P < .001]; gross motor skills, 48.7 vs 53.0 [P = .002]; pain/itching, 15.8 vs 33.5 [P < .001]; and worry/concern, 31.6 vs 44.9 [P < .001]). Pediatric burn survivors had higher scores in language, emotional behavior, and family functioning domains compared with healthy children in later months., Conclusions and Relevance: This study demonstrates significant deficits in multiple functional domains across pediatric burn survivors compared with controls. Recovery curves can be used to recognize deviation from the expected course and tailor care to patient needs.
