Abstract
Summary Background Stroke disproportionately affects people in low-income and middle-income countries. Although improvements in stroke care and outcomes have been reported in high-income countries, little is known about practice and outcomes in low and middle-income countries. We aimed to compare patterns of care available and their association with patient outcomes across countries at different economic levels. Methods We studied the patterns and effect of practice variations (ie, treatments used and access to services) among participants in the INTERSTROKE study, an international observational study that enrolled 13 447 stroke patients from 142 clinical sites in 32 countries between Jan 11, 2007, and Aug 8, 2015. We supplemented patient data with a questionnaire about health-care and stroke service facilities at all participating hospitals. Using univariate and multivariate regression analyses to account for patient casemix and service clustering, we estimated the association between services available, treatments given, and patient outcomes (death or dependency) at 1 month. Findings We obtained full information for 12 342 (92%) of 13 447 INTERSTROKE patients, from 108 hospitals in 28 countries; 2576 from 38 hospitals in ten high-income countries and 9766 from 70 hospitals in 18 low and middle-income countries. Patients in low-income and middle-income countries more often had severe strokes, intracerebral haemorrhage, poorer access to services, and used fewer investigations and treatments (p Interpretation Evidence-based treatments, diagnostics, and stroke units were less commonly available or used in low and middle-income countries. Access to stroke units and appropriate use of antiplatelet treatment were associated with improved recovery. Improved care and facilities in low-income and middle-income countries are essential to improve outcomes. Funding Chest, Heart and Stroke Scotland.

Summary Background The contribution of modifiable risk factors to the increasing global and regional burden of stroke is unclear, but knowledge about this contribution is crucial for informing stroke prevention strategies. We used data from the Global Burden of Disease Study 2013 (GBD 2013) to estimate the population-attributable fraction (PAF) of stroke-related disability-adjusted life-years (DALYs) associated with potentially modifiable environmental, occupational, behavioural, physiological, ...

Summary Background Stroke is a leading cause of death and disability, especially in low-income and middle-income countries. We sought to quantify the importance of potentially modifiable risk factors for stroke in different regions of the world, and in key populations and primary pathological subtypes of stroke. Methods We completed a standardised international case-control study in 32 countries in Asia, America, Europe, Australia, the Middle East, and Africa. Cases were patients with acute firs...

Summary Background Aspirin is recommended for secondary prevention after transient ischaemic attack (TIA) or ischaemic stroke on the basis of trials showing a 13% reduction in long-term risk of recurrent stroke. However, the risk of major stroke is very high for only the first few days after TIA and minor ischaemic stroke, and observational studies show substantially greater benefits of early medical treatment in the acute phase than do longer-term trials. We hypothesised that the short-term ben...

BackgroundRoutine monitoring of the quality of stroke care is becoming increasingly important since patient outcomes could be improved with better access to proven treatments. It remains unclear how many countries have established a national registry for monitoring stroke care.AimsTo describe the current status of national, hospital-based stroke registries that have a focus on monitoring access to evidence-based care and patient outcomes and to summarize the main features of these registries.Sum...

Background and Purpose—Further research is needed to better identify the methods of evaluating processes and outcomes of stroke care. We investigated whether achieving 4 evidence-based components of a care bundle in a Scotland-wide population with ischemic stroke is associated with 30-day and 6-month outcomes. Methods—Using national datasets, we looked at the effect of 4 standards (stroke unit entry on calendar day of admission [day 0] or day following [day 1], aspirin on day 0 or day 1, scan on...

Stroke disease is the second leading cause of death in the world. Even if stroke incidence remains stable, the number of new acute strokes in Europe is projected to increase markedly by 2025. In 2007, the SITS-MOST trial provided the first conclusive evidence that intravenous thrombolysis with recombinant tissue plasminogen activator (rTPA) was beneficial in the acute period for patients with cerebral infarct. Evidence from the same year showed that decompressive hemicraniectomy can double the r...

The mean INTERHEART Risk Score was highest in high-income countries, intermediate in middle-income countries, and lowest in low-income countries (P<0.001). However, the rates of major cardiovascular events (death from cardiovascular causes, myocardial infarction, stroke, or heart failure) were lower in high-income countries than in middle- and low-income countries (3.99 events per 1000 personyears vs. 5.38 and 6.43 events per 1000 person-years, respectively; P<0.001). Case fatality rates were al...

Background The Charlson Comorbidity Index (CCI) is commonly used in outcome and mortality studies. Our aim was to investigate the association between CCI score and the functional outcome and mortality 6 months after ischemic stroke (IS) or intracerebral hemorrhage. Methods This was a prospective observational cohort of patients with spontaneous intracerebral hemorrhage and IS admitted to the stroke unit during 18 months. The modified Rankin scale (mRS) score was obtained for subjects 6 months af...

Summary Stroke units have become established as the central component of modern stroke services. However, most stroke-unit trials and service developments have been done in high-income countries, which raises the question of whether such care is relevant and applicable to low-income and middle-income settings. To address this question, we first need to show that stroke units are likely to provide important health gains to populations. Second, we need to identify those components of stroke units ...

Summary With over 2 million new cases annually, stroke is associated with the highest disability-adjusted life-years lost of any disease in China. The burden is expected to increase further as a result of population ageing, an ongoing high prevalence of risk factors (eg, hypertension), and inadequate management. Despite improved access to overall health services, the availability of specialist stroke care is variable across the country, and especially uneven in rural areas. In-hospital outcomes ...

Abstract Because of the demographic shift and the increased proportion of patients surviving acute critical illnesses, the number of people living with severely disabling chronic diseases and, consequently, the demand for rehabilitation are expected to increase sharply over time. As underscored by the World Health Organization, there is substantial evidence that the provision of inpatient rehabilitation in specialized rehabilitation units to people with complex needs is effective in fostering fu...
