SummaryBackgroundThe Global Burden of Diseases, Injuries, and Risk Factors Study 2017 (GBD 2017) includes a comprehensive assessment of incidence, prevalence, and years lived with disability (YLDs) for 354 causes in 195 countries and territories from 1990 to 2017. Previous GBD studies have shown how the decline of mortality rates from 1990 to 2016 has led to an increase in life expectancy, an ageing global population, and an expansion of the non-fatal burden of disease and injury. These studies have also shown how a substantial portion of the world's population experiences non-fatal health loss with considerable heterogeneity among different causes, locations, ages, and sexes. Ongoing objectives of the GBD study include increasing the level of estimation detail, improving analytical strategies, and increasing the amount of high-quality data.MethodsWe estimated incidence and prevalence for 354 diseases and injuries and 3484 sequelae. We used an updated and extensive body of literature studies, survey data, surveillance data, inpatient admission records, outpatient visit records, and health insurance claims, and additionally used results from cause of death models to inform estimates using a total of 68 781 data sources. Newly available clinical data from India, Iran, Japan, Jordan, Nepal, China, Brazil, Norway, and Italy were incorporated, as well as updated claims data from the USA and new claims data from Taiwan (province of China) and Singapore. We used DisMod-MR 2.1, a Bayesian meta-regression tool, as the main method of estimation, ensuring consistency between rates of incidence, prevalence, remission, and cause of death for each condition. YLDs were estimated as the product of a prevalence estimate and a disability weight for health states of each mutually exclusive sequela, adjusted for comorbidity. We updated the Socio-demographic Index (SDI), a summary development indicator of income per capita, years of schooling, and total fertility rate. Additionally, we calculated differences between male and female YLDs to identify divergent trends across sexes. GBD 2017 complies with the Guidelines for Accurate and Transparent Health Estimates Reporting.FindingsGlobally, for females, the causes with the greatest age-standardised prevalence were oral disorders, headache disorders, and haemoglobinopathies and haemolytic anaemias in both 1990 and 2017. For males, the causes with the greatest age-standardised prevalence were oral disorders, headache disorders, and tuberculosis including latent tuberculosis infection in both 1990 and 2017. In terms of YLDs, low back pain, headache disorders, and dietary iron deficiency were the leading Level 3 causes of YLD counts in 1990, whereas low back pain, headache disorders, and depressive disorders were the leading causes in 2017 for both sexes combined. All-cause age-standardised YLD rates decreased by 3·9% (95% uncertainty interval [UI] 3·1–4·6) from 1990 to 2017; however, the all-age YLD rate increased by 7·2% (6·0–8·4) while the total sum of global YLDs increased from 562 mil...
Objective and Design: We conducted a multinational observational study on features of consecutive acute ischemic stroke (AIS), intracranial hemorrhage (ICH), and cerebral venous or sinus thrombosis (CVST) among SARS-CoV-2 infected patients. Main Outcome Measures: We investigated the association of demographics, clinical data, geographical regions, and countries’ health expenditure among AIS patients with the risk of large vessel occlusion (LVO), stroke severity as measured by National Institute of Health stroke scale (NIHSS), and stroke subtype as measured by the TOAST criteria. Additionally, we applied unsupervised machine learning algorithms to uncover possible similarities among stroke patients. Results: Among the 136 tertiary centers of 32 countries who participated in this study, 71 centers from 17 countries had at least one eligible stroke patient. Out of 432 patients included, 323(74.8%) had AIS, 91(21.1%) ICH, and 18(4.2%) CVST. Among 23 patients with subarachnoid hemorrhage, 16(69.5%) had no evidence of aneurysm. A total of 183(42.4%) patients were women, 104(24.1%) patients were younger than 55 years, and 105(24.4%) patients had no identifiable vascular risk factors. Among 380 patients who had known interval onset of the SARS-CoV-2 and stroke, 144(37.8%) presented to the hospital with chief complaints of stroke-related symptoms, with asymptomatic or undiagnosed SARS-CoV-2 infection. Among AIS patients 44.5% had LVO; 10% had small artery occlusion according to the TOAST criteria. We observed a lower median NIHSS (8[3-17], versus 11[5-17]; p=0.02) and higher rate of mechanical thrombectomy (12.4% versus 2%; p<0.001) in countries with middle to high-health expenditure when compared to countries with lower health expenditure. The unsupervised machine learning identified 4 subgroups, with a relatively large group with no or limited comorbidities. Conclusions and Relevance: We observed a relatively high number of young, and asymptomatic SARS-CoV-2 infections among stroke patients. Traditional vascular risk factors were absent among a relatively large cohort of patients. The stroke severity was lower and rate of mechanical thrombectomy was higher among countries with middle to high-health expenditure.
Conclusion Thrombolysis rates in New Zealand continue to rise and now surpass the more recent 10% Ministry of Health target. The continued reduction in door-to-needle time is also an indication of continued service improvement resulting in better patient outcome. However, there are still to be opportunities for improvement.
Introduction: The REGIONS Care project is a New Zealand (NZ) based nationwide project that aims to capture all stroke patients admitted to NZ hospitals exploring ethic and geographic inequities in stroke care access and patient outcomes. Findings from this study will advise the National Stroke Programme strategy. This project includes an organisational survey to assess current availability of interventions and general management approaches in each hospital. Methods: This is a prospective registry based study with up to one year follow-up. Patients are registered into a central database by hospital teams and follow-up is achieved primarily via telephone calls. The outcome data will be adjusted for baseline function and stroke severity among other factors. At this stage the main study is ongoing, but the organisational survey has been completed. Analysis has not yet been finalised. Final and validated results will be presented at the meeting. Results: All NZ hospitals were approached and 100% completed the online survey. Preliminary results found that of these hospitals 82% have an acute stroke unit, 86% have a TIA pathway, but only 57% offer rapid access specialist TIA services. 100% offer thrombolysis, 93% use an EMS pre-notification and rapid ED triage system, and 75% an in-hospital ‘code stroke’ alert. 11% offer onsite thrombectomy, and a further 41% access thrombectomy via rapid inter-hospital transfer. 82% offer inter-disciplinary team review within 24 hours of admission and while 100% have access to OT, PT, and SLT, only 27% have access to a psychologist. 100% offer inpatient and 92% community rehabilitation service while only 11% offer early supported discharge programmes. Only 31% of hospitals have a dedicated stroke rehab unit. While 88% routinely provide stroke patient education, only 52% provide individualised stroke care plans at discharge. Conclusion: These preliminary results show good access to thrombolysis and multi-disciplinary stroke care. However, improvements are needed in access to thrombectomy, rapid specialist TIA services, early supported discharge, dedicated stroke rehabilitation units, psychologists, and individualised patient care plans. Final and additional results will be presented at the conference.
