Abstract
BACKGROUND Stroke is the leading cause of mortality in China, with limited evidence of in-hospital burden obtained from nationwide surveys. We aimed to monitor and track the temporal trends and rural-urban disparities in cerebrovascular risk factors, management and outcomes from 2005 to 2015. METHODS We used a two-stage random sampling survey to create a nationally representative sample of patients admitted for ischaemic stroke in 2005, 2010 and 2015. We sampled participating hospitals with an economic-geographical region-stratified random-sampling approach first and then obtained patients with a systematic sampling approach. We weighed our survey data to estimate the national-level results and assess changes from 2005 to 2015. RESULTS We analysed 28 277 ischaemic stroke admissions from 189 participating hospitals. From 2005 to 2015, the estimated national hospital admission rate for ischaemic stroke per 100 000 people increased (from 75.9 to 402.7, Ptrend<0.001), and the prevalence of risk factors, including hypertension, diabetes, dyslipidaemia and current smoking, increased. The composite score of diagnostic tests for stroke aetiology assessment (from 0.22 to 0.36, Ptrend<0.001) and secondary prevention treatments (from 0.46 to 0.70, Ptrend<0.001) were improved. A temporal decrease was found in discharge against medical advice (DAMA) (from 15.2% (95% CI 13.7% to 16.7%) to 8.6% (8.1% to 9.0%); adjusted Ptrend=0.046), and decreases in in-hospital mortality (0.7% in 2015 vs 1.8% in 2005; adjusted OR (aOR) 0.52; 95% CI 0.32 to 0.85) and the composite outcome of in-hospital mortality or DAMA (8.4% in 2015 vs 13.9% in 2005; aOR 0.65; 95% CI 0.47 to 0.89) were observed. Disparities between rural and urban hospitals narrowed; however, disparities persisted in in-hospital management (brain MRI: rural-urban difference from -14.4% to -11.2%; cerebrovascular assessment: from -20.3% to -16.7%; clopidogrel: from -2.1% to -10.3%; anticoagulant for atrial fibrillation: from -10.9% to -8.2%) and in-hospital outcomes (DAMA: from 2.7% to 5.0%; composite outcome of in-hospital mortality or DAMA: from 2.4% to 4.6%). CONCLUSIONS From 2005 to 2015, improvements in hospital admission and in-hospital management for ischaemic stroke in China were found. A temporal improvement in DAMA and improvements in in-hospital mortality and the composite outcome of in-hospital mortality or DAMA were observed. Disparities between rural and urban hospitals generally narrowed but persisted.

Trends in the incidence and mortality of intracerebral hemorrhage, and the associated risk factors, in Denmark from 2004 to 2017. Eur J Neurol 2021; 29:168-177. [PMID: 34528344 DOI: 10.1111/ene.15110] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2021] [Revised: 09/10/2021] [Accepted: 09/11/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND AND PURPOSE The distribution of the major modifiable risk factors for intracerebral hemorrhage (ICH) changes rapidly. These changes call for contemporary data from large-scale population-based studies. The aim of the present study was to examine trends in incidence, risk factors, and mortality in ICH patients from 2004 to 2017. METHODS In a population-based cohort study, we calculated age- and sex-standardized incidence rates (SIRs), incidence rates (IRs) stratified by age and sex per 100,000 person-years, and trends in risk profiles. We estimated absolute mortality risk, and the Cox proportional hazards regression multivariable-adjusted hazard ratios for 30-day and 1-year mortality. RESULTS We included 16,902 patients (53% men; median age 75 years) from 2004 to 2017. The SIR of ICH decreased from 33 (95% confidence interval [CI] 32-34) in 2004/2005 to 28 (95% CI 27-29) in 2016/2017. Among patients aged ≥70 years, the IR decreased from 137 (95% CI 130-144) in 2004/2005 to 112 (95% CI 106-117) in 2016/2017. The IR in patients aged <70 years was unchanged. From 2004 to 2017, the proportion of patients with hypertension increased from 49% to 66%, the use of oral anticoagulants increased from 7% to 18%, and the use of platelet inhibitors decreased from 40% to 28%. The adjusted hazard ratio for 30-day mortality in 2016/2017 was 0.94 (95% CI 0.89-1.01) and 1-year mortality was 0.98 (95% CI 0.93-1.04) compared with 2004/2005. CONCLUSION The incidence of spontaneous ICH decreased from 2004 to 2017, with no clear trend in mortality. The risk profile of ICH patients changed substantially, with increasing proportions of hypertension and anticoagulant treatment. Given the high mortality rate of ICH, further advances in prevention and treatment are urgently needed.

Abstract
BACKGROUND This article investigates changes in disease prevalence, incidence, and mortality among four cohorts of older persons in the Health and Retirement Study. METHODS We examine two cohorts initially aged 51 to 61, whom we call younger cohorts, and two older cohorts aged 70 to 80 at the start of observation. Each of the paired cohorts was born about 10 years apart. We follow the cohorts for approximately 10 years. RESULTS The prevalence of cancer, stroke, and diabetes increased in later-born cohorts; while the prevalence of myocardial infarction decreased markedly in both later-born cohorts. The incidence of heart disease, myocardial infarction, and stroke decreased among those in the later-born older cohort; while only the incidence of myocardial infarction decreased in the later-born younger cohort. On the other hand, diabetes incidence increased among those in both later-born cohorts. Death rates among those with heart disease, cancer, and diabetes decreased in the later-born cohorts. The declining incidence of three cardiovascular conditions among those who are over age 70 reflects improving population health and has resulted in stemming the increase in prevalence of people with heart disease and stroke. DISCUSSION While these results provide some important signs of improving population health, especially among those over 70; trends for those less than 70 in the United States are not as positive.

Abstract
BACKGROUND Accurate assessment of the burden of stroke, a major cause of disability and death, is crucial. We aimed to estimate rates of validated ischaemic stroke hospitalizations in the USA during 1998-2011. METHODS We used the Atherosclerosis Risk in Communities (ARIC) study cohort's adjudicated stroke data for participants aged ≥55 years, to construct validation models for each International Classification of Diseases (ICD)-code group and patient covariates. These models were applied to the Nationwide Inpatient Sample (NIS) data to estimate the probability of validated ischaemic stroke for each eligible hospitalization. Rates and trends in NIS using ICD codes vs estimates of validated ischaemic stroke were compared. RESULTS After applying validation models, the estimated annual average rate of validated ischaemic stroke hospitalizations in the USA during 1998-2011 was 3.37 [95% confidence interval (CI): 3.31, 3.43) per 1000 person-years. Validated rates declined during 1998-2011 from 4.7/1000 to 2.9/1000; however, the decline was limited to 1998-2007, with no further decline subsequently through 2011. Validation models showed that the false-positive (∼23% of strokes) and false-negative rates of ICD-9-CM codes in primary position for ischaemic stroke approximately cancel. Therefore, estimates of ischaemic stroke hospitalizations did not substantially change after applying validation models. CONCLUSIONS Overall, ischaemic stroke hospitalization rates in the USA have declined during 1998-2007, but no further decline was observed from 2007 to 2011. Validated ischaemic stroke hospitalizations estimates were similar to published estimates of hospitalizations with ischaemic stroke ICD codes in primary position. Validation of national discharge data using prospective chart review data is important to estimate the accuracy of reported burden of stroke.

Abstract
We aimed to provide estimates of the volume and associated charges of acute ischemic stroke (AIS) visits in the US, as well as to assess predictors of patient disposition following an emergency department (ED) visit for AIS. Our study was conducted using the 2010–2013 data from the Nationwide Emergency Department Sample. We identified adult visits with AIS as the primary diagnosis. A generalized linear model was used to calculate mean charges per visit after adjusting for covariates. Multinomial logistic regression was used to assess predictors of patient disposition following an ED visit for AIS. The national incidence did not appreciably change over time, increasing from 26.4 to 27.0 visits per 10,000 adults. Adjusted mean charges per event were highest in the West, increasing from $3,761 in 2010 to $4,575 in 2013. Multinomial logistic regression showed that older age was associated with increased likelihood of both hospital admission and mortality in the ED, while male sex was associated with lower odds of mortality in the ED. Despite improvements in primary and secondary prevention of cardiovascular disease, AIS remains a significant burden on the health care system with a high volume of ED visits and increasing charges for care.

Abstract
Background Transient ischemic attack (TIA) is a major predictor of subsequent stroke. No study has assessed nation‐wide trends in hospitalization for TIA in the United States. Methods and Results Temporal trends in hospitalization for TIA (International Classification of Diseases, Ninth Revision code 435.0–435.9) from 2000 to 2010 were assessed among adults aged ≥25 years using the Nationwide Inpatient Sample. Age‐, sex‐, and race/ethnic‐specific TIA hospitalization rates were calculated using the weighted number of hospitalizations as the numerator and the US population as the denominator. Age‐adjusted rates were standardized to the 2000 US Census population. From 2000 to 2010, age‐adjusted TIA hospitalization rates decreased from 118 to 83 per 100 000 (overall rate reduction, −29.7%). Age‐specific TIA hospitalization rates increased for individuals aged 24 to 44 years (10–11 per 100 000), but decreased for individuals aged 45 to 64 (74 to 65 per 100 000), 65 to 84 (398 to 245 per 100 000), and ≥85 years (900 to 619 per 100 000). Blacks had the highest age‐adjusted yearly hospitalization rates, followed by Hispanics and whites (124, 82, and 67 per 100 000 in 2010). Rates slightly increased for blacks, but decreased for Hispanics and whites. Compared to women, age‐adjusted TIA hospitalization rates were lower and declined more steeply in men (132 to 89 per 100 000 versus 134 to 97 per 100 000). Conclusions Although overall TIA hospitalizations have decreased in the United States, the reduction has been more pronounced among older individuals, men, whites, and Hispanics. These findings highlight the need to target risk‐factor control among women, blacks, and individuals aged <45 years.

Abstract
BACKGROUND AND PURPOSE Little attention was paid to the transition of care for stroke that may partially explain the long-term trend of stroke rates. We aimed to test the trend of hospitalization attributable to stroke in US adults. METHODS Data from National Hospital Discharge Surveys 1980-2010 in patients aged ≥18 (n = 6,527,304) were analyzed to examine the trend of patients with first-list diagnoses of stroke. Stroke comorbidities were classified in stroke patients with second- to seven-listed diagnoses of coronary heart disease, hypertension, diabetes, arrhythmias, or hyperlipidemia. Stroke trends by survey years and birth cohorts were analyzed using univariate, multivariate, and birth cohorts methods. RESULTS Of the total study sample, the prevalence of hospitalization due to stroke was 22.99%, 30.00%, and 27.03% in years of 1980-1989, 1990-1999, and 2000-2010 in males, and 17.30%, 22.04%, and 19.34% in females, respectively. Overall, hospitalization rates in stroke patients significantly increased among adults aged <65, and decreased in adults aged ≥65. There was an increase in stroke hospitalization rate in the old adults aged ≥65 in recent birth cohorts. Significant increased trends of comorbid hypertension, diabetes, arrhythmias, and hyperlipidemia were observed from 1980 to 2010. CONCLUSION A significant increase in stroke hospitalization rate was observed in adults aged <65 in the past three decades, and in old adults in recent years. Increases in stroke comorbidity rates were observed in all age groups. Findings from the study highlight that both public health and clinical practices face a serious challenge in controlling this unwelcome increased stroke trend.

Background Population‐based studies have revealed declining acute ischemic stroke (AIS) hospitalization rates in the United States, but no study has assessed recent temporal trends in race/ethnic‐, age‐, and sex‐specific AIS hospitalization rates. Methods and Results Temporal trends in hospitalization for AIS from 2000 to 2010 were assessed among adults ≥25 years using the Nationwide Inpatient Sample. Age‐, sex‐, and race/ethnic‐specific and age‐adjusted stroke hospitalization rates were calculated using the weighted number of hospitalizations and US census data. From 2000 to 2010, age‐adjusted stroke hospitalization rates decreased from 250 to 204 per 100 000 (overall rate reduction 18.4%). Age‐specific AIS hospitalization rates decreased for individuals aged 65 to 84 years (846 to 605 per 100 000) and ≥85 years (2077 to 1618 per 100 000), but increased for individuals aged 25 to 44 years (16 to 23 per 100 000) and 45 to 64 years (149 to 156 per 100 000). Blacks had the highest age‐adjusted yearly hospitalization rates, followed by Hispanics and whites (358, 170, and 155 per 100 000 in 2010). Age‐adjusted AIS hospitalization rates increased for blacks but decreased for Hispanics and whites. Age‐adjusted AIS hospitalization rates were lower in women and declined more steeply compared to men (272 to 212 per 100 000 in women versus 298 to 245 per 100 000 in men). Conclusions Although overall stroke hospitalizations declined in the United States, the reduction was more pronounced among older individuals, women, Hispanics, and whites. Renewed efforts at targeting risk factor control among vulnerable individuals may be warranted.

Abstract
The past century was a period of increasing life expectancy throughout the age range. This resulted in more people living to old age and to spending more years at the older ages. It is likely that increases in life expectancy at older ages will continue, but life expectancy at birth is unlikely to reach levels above 95 unless there is a fundamental change in our ability to delay the aging process. We have yet to experience much compression of morbidity as the age of onset of most health problems has not increased markedly. In recent decades, there have been some reductions in the prevalence of physical disability and dementia. At the same time, the prevalence of disease has increased markedly, in large part due to treatment which extends life for those with disease. Compressing morbidity or increasing the relative healthspan will require "delaying aging" or delaying the physiological change that results in disease and disability. While moving to life expectancies above age 95 and compressing morbidity substantially may require significant scientific breakthroughs; significant improvement in health and increases in life expectancy in the United States could be achieved with behavioral, life style, and policy changes that reduce socioeconomic disparities and allow us to reach the levels of health and life expectancy achieved in peer societies.

Abstract
Background and Purpose—
Ischemic stroke incidence has declined in industrialized countries the last decades, with possible exception for the youngest age groups. We estimated age- and sex-specific trends in incidence and case fatality of first-ever ischemic stroke between 1977 and 2010 in a Norwegian municipality.
Methods—
Age-adjusted time trends in incidence from 1977 to 2010 were estimated by fractional polynomial and Poisson regression, and case fatality by logistic regression in 36 575 participants of the population-based Tromsø Study.
Results—
There were 1214 first-ever ischemic strokes within a total follow-up time of 611 176 person-years. The overall age- and sex-adjusted incidence decreased by 24% in 1995 to 2010. In women aged 30 to 49 years, the incidence increased significantly from 1980 to 2010. In men aged 30 to 49 years, there was a nonsignificant, rising trend from 1977 to 2010. Men aged 50 to 64 years had similar incidence in 2010 compared with 1989. From the mid-1990s to 2010, the incidence declined significantly in women aged 50 to 74 years and in men aged 65 to 74 years, but remained stable in those aged ≥75 years. Case fatality decreased significantly in men aged 30 to 84 years from 1995 to 2010, whereas there was no significant change in women.
Conclusions—
Age-adjusted incidence of first-ever ischemic stroke increased in young women, declined in women aged 50 to 74 years and men aged 65 to 74 years and remained stable among the oldest. Case fatality declined in men aged 30 to 84 years, but not in women.

Abstract
BACKGROUND Incidence of ischemic stroke and associated in-hospital mortality is decreasing in Western populations, while the prevalence of diabetes, a well-known risk factor for ischemic stroke, is progressively rising. This study was aimed at evaluating the effect of diabetes on ischemic stroke hospitalization and in-hospital mortality after ischemic stroke. METHODS Discharges with diagnosis of ischemic stroke were identified in a database containing all hospitalizations of resident population of Tuscany, Italy, over years 2004-2011. Cases with diabetes were identified through specific drug prescriptions, official certifications or previous hospital diagnosis. Rates of annual ischemic stroke incidence and related in-hospital mortality were separately calculated for gender and age class, in subjects with and without diabetes. RESULTS Sixty-five thousand one hundred sixty-five hospital discharges with ischemic stroke diagnosis were identified. Diabetes was associated with increased risk of stroke odds ratio(95% confidence interval):1.31(1.28-1.34) in men and 1.24(1.21-1.37) in women. Diabetic women, compared with men, had a higher in-hospital mortality risk after ischemic stroke (odds ratio:1.32; 1.06-1.64), whereas in non-diabetic subjects, there was no difference between genders. Incidence of ischemic stroke has declined in non-diabetic subjects, except for women aged ≤70 years; a similar reduction was observed for in-hospital mortality. Among diabetic patients, conversely, annual incidence of ischemic stroke rose by 3% in the elderly people (>70 years), and annual mortality trend remained unchanged. CONCLUSIONS In the last decade, the incidence of ischemic stroke and of related in-hospital mortality declined in persons without diabetes, while increasing among diabetic patients of advanced age. Women with diabetes, compared with men, had a higher in-hospital mortality risk.

Abstract
OBJECTIVES To provide a national estimate of the incidence of hospitalizations due to osteoporotic fractures (OFs) in women; compare this with the incidence of myocardial infarction (MI), stroke, and breast cancer; and assess temporal trends in the incidence and length of hospitalizations. PATIENTS AND METHODS The study included all women 55 years and older at the time of admission, admitted to a hospital participating in the US Nationwide Inpatient Sample for an outcome of interest. We performed a retrospective analysis of hospitalizations for OFs (hip, forearm, spine, pelvis, distal femur, wrist, and humerus), MI, stroke, or breast cancer, using the US Nationwide Inpatient Sample, 2000-2011. RESULTS From 2000 to 2011, there were 4.9 million hospitalizations for OF, 2.9 million for MI, 3.0 million for stroke, and 0.7 million for breast cancer. Osteoporotic fractures accounted for more than 40% of the hospitalizations in these 4 outcomes, with an age-adjusted rate of 1124 admissions per 100,000 person-years. In comparison, MI, stroke, and breast cancer had age-adjusted incidence rates of 668, 687, and 151 admissions per 100,000 person-years, respectively. The annual total population facility-related hospital cost was highest for hospitalizations due to OFs ($5.1 billion), followed by MI ($4.3 billion), stroke ($3.0 billion), and breast cancer ($0.5 billion). CONCLUSION These data provide evidence that in US women 55 years and older, the hospitalization burden of OFs and population facility-related hospital cost is greater than that of MI, stroke, or breast cancer. Prioritization of bone health and supporting programs such as fracture liaison services is needed to reduce this substantial burden.

Abstract
Background A recent systematic review of epidemiological studies reported intracerebral hemorrhage (ICH) incidence and mortality as unchanged over time; however, comparisons between studies conducted in different health services obscure assessment of trends. We explored trends in ICH rates in a large, representative population in New South Wales, Australia's most populous state (≈7.3 million). Methods and Results Adult hospitalizations with a principal ICH diagnosis from 2001 to 2009 were linked to death registrations through to June 30, 2010. Trends for overall, fatal, and nonfatal ICH rates within 30 days and fatal rates for 30‐day survivors at 365 days were calculated. There were 11 332 ICH patient admissions meeting eligibility criteria, yielding a crude hospitalization rate of 25.2 per 100 000 (age‐standardized rate: 17.2). Age‐ and sex‐adjusted overall rates significantly declined by an average of 1.6% per year (P=0.03). Fatal ICH declined by an average of 2.6% per year (P=0.004). For 30‐day survivors, a nonsignificant decline of 2.3% per year in fatal ICH at 365 days was estimated (P=0.17). Male sex and birth in the Oceania region and Asia were associated with an increased ICH risk, although this depended on age. Approximately 12% of ICH admissions would be prevented if the socioeconomic circumstances of the population equated with those of the least disadvantaged. Conclusions Overall and fatal ICH rates have fallen in this large Australian population. Improvements in cardiovascular prevention and acute care may explain declining rates. There was no evidence of an increase in devastated survivors because the longer term mortality of 30‐day survivors has not increased over time.

Abstract
OBJECTIVE To determine trends in incidence and mortality of intracerebral hemorrhage (ICH) in a rigorous population-based study. METHODS We identified all cases of spontaneous ICH in a South Texas community from 2000 to 2010 using rigorous case ascertainment methods within the Brain Attack Surveillance in Corpus Christi Project. Yearly population counts were determined from the US Census, and deaths were determined from state and national databases. Age-, sex-, and ethnicity-adjusted incidence was estimated for each year with Poisson regression, and a linear trend over time was investigated. Trends in 30-day case fatality and long-term mortality (censored at 3 years) were estimated with log-binomial or Cox proportional hazards models adjusted for demographics, stroke severity, and comorbid disease. RESULTS A total of 734 cases of ICH were included. The age-, sex-, and ethnicity-adjusted ICH annual incidence rate was 5.21 per 10,000 (95% confidence interval [CI] 4.36, 6.24) in 2000 and 4.30 per 10,000 (95% CI 3.21, 5.76) in 2010. The estimated 10-year change in demographic-adjusted ICH annual incidence rate was -31% (95% CI -47%, -11%). Yearly demographic-adjusted 30-day case fatality ranged from 28.3% (95% CI 19.9%, 40.3%) in 2006 to 46.5% (95% CI 35.5, 60.8) in 2008. There was no change in ICH case fatality or long-term mortality over time. CONCLUSIONS ICH incidence decreased over the past decade, but case fatality and long-term mortality were unchanged. This suggests that primary prevention efforts may be improving over time, but more work is needed to improve ICH treatment and reduce the risk of death.

Abstract
BACKGROUND AND PURPOSE Stroke mortality has been declining since the early 20th century. The reasons for this are not completely understood, although the decline is welcome. As a result of recent striking and more accelerated decreases in stroke mortality, stroke has fallen from the third to the fourth leading cause of death in the United States. This has prompted a detailed assessment of the factors associated with the change in stroke risk and mortality. This statement considers the evidence for factors that have contributed to the decline and how they can be used in the design of future interventions for this major public health burden. METHODS Writing group members were nominated by the committee chair and co-chair on the basis of their previous work in relevant topic areas and were approved by the American Heart Association Stroke Council's Scientific Statements Oversight Committee and the American Heart Association Manuscript Oversight Committee. The writers used systematic literature reviews, references to published clinical and epidemiological studies, morbidity and mortality reports, clinical and public health guidelines, authoritative statements, personal files, and expert opinion to summarize evidence and to indicate gaps in current knowledge. All members of the writing group had the opportunity to comment on this document and approved the final version. The document underwent extensive American Heart Association internal peer review, Stroke Council leadership review, and Scientific Statements Oversight Committee review before consideration and approval by the American Heart Association Science Advisory and Coordinating Committee. RESULTS The decline in stroke mortality over the past decades represents a major improvement in population health and is observed for both sexes and for all racial/ethnic and age groups. In addition to the overall impact on fewer lives lost to stroke, the major decline in stroke mortality seen among people <65 years of age represents a reduction in years of potential life lost. The decline in mortality results from reduced incidence of stroke and lower case-fatality rates. These significant improvements in stroke outcomes are concurrent with cardiovascular risk factor control interventions. Although it is difficult to calculate specific attributable risk estimates, efforts in hypertension control initiated in the 1970s appear to have had the most substantial influence on the accelerated decline in stroke mortality. Although implemented later, diabetes mellitus and dyslipidemia control and smoking cessation programs, particularly in combination with treatment of hypertension, also appear to have contributed to the decline in stroke mortality. The potential effects of telemedicine and stroke systems of care appear to be strong but have not been in place long enough to indicate their influence on the decline. Other factors had probable effects, but additional studies are needed to determine their contributions. CONCLUSIONS The decline in stroke mortality is real and represents a major public health and clinical medicine success story. The repositioning of stroke from third to fourth leading cause of death is the result of true mortality decline and not an increase in mortality from chronic lung disease, which is now the third leading cause of death in the United States. There is strong evidence that the decline can be attributed to a combination of interventions and programs based on scientific findings and implemented with the purpose of reducing stroke risks, the most likely being improved control of hypertension. Thus, research studies and the application of their findings in developing intervention programs have improved the health of the population. The continued application of aggressive evidence-based public health programs and clinical interventions is expected to result in further declines in stroke mortality.

Abstract
BACKGROUND A study performed in Hong Kong of catheter angiography after ICH found a high rate of structural lesions in patients 45 years of age or younger, without a history of hypertension, or with lobar hemorrhage. We hypothesized that a clinical decision rule based on these Hong Kong criteria would reliably identify patients who require MRI after ICH. METHODS We identified all patients admitted with ICH to our medical center during a 5-year period who underwent brain MRI. Patients were excluded if the history revealed an obvious cause of ICH. Two study neurologists independently adjudicated whether MRI revealed the cause of ICH. We devised a rule recommending MRI if patients met one or more Hong Kong criteria, and calculated the proportion of patients with diagnostic MRI studies who would have been identified by this rule. We also examined the performance of a modified rule using age ≤ 55 years. RESULTS The original Hong Kong rule applied to 102 of the 148 patients in our cohort (69%), and would have recommended MRI in 25 of 27 patients with diagnostic MRI studies (93%, 95% CI 76-99%). The modified rule applied to 110 patients (74%), and would have recommended MRI in all 27 patients with diagnostic MRI studies (100%, 95% CI 91-100%). CONCLUSIONS A rule based on simple clinical criteria may be useful for stratifying the yield of MRI after ICH. If validated in further studies, such a rule could reduce the number of unnecessary MRI studies after ICH, leading to more cost-effective care.

Abstract
AIMS The objective of this study is (i) to evaluate trends in the incidence rates of stroke survivors aged 60 years and older over a 11-year period in the Australian Capital Territory (ACT) and (ii) to forecast future trends in Australia until 2051. METHODS Analysis of age- and sex-specific standardized incidence rates of older first-ever stroke survivors in ACT from 1999-2000 to 2009-2010 and projections of number of stroke survivors (NSS) in 2021 and 2051 using 2 models based only on (i) demographic changes and (ii) assuming changing of both incidence rates and demography. RESULTS In the ACT in the first decade of the 21st century, the absolute numbers and age-adjusted standardized incidence rates of stroke survivors (measured as a function of age and period) increased among both men and women aged 60 years or older. The trend toward increased survival rates in both sexes was driven mainly by population aging, whereas the effect of stroke year was more pronounced in men compared with women. The absolute NSS (and the financial burden to the society) in Australia is predicted to increase by 35.5%-59.3% in 2021 compared with 2011 and by 1.6- to 4.6-fold in 2051 if current only demographic (first number) or both demographic and incidence trends (second number) continue. CONCLUSIONS Our study demonstrates favorable trends in stroke survivor rates in Australia in the first decade of the new millennium and projects in the foreseeable future significant increases in the absolute numbers of older stroke survivors, especially among those aged 70 years or older and men.

Abstract
BACKGROUND The frequencies of treatment for cardiovascular risk factors are poorly documented in large populations, particularly according to the presence or absence of cardiovascular disease (CVD). AIMS To assess frequencies of reimbursements for antihypertensive, lipid-lowering and antidiabetic medications in France among national health insurance beneficiaries in 2010 and their associations according to age, sex, French regions, level deprivation and the presence of certain CVD. METHODS Treatment frequencies were calculated among the beneficiaries (58 million people) on the basis of reimbursements for three specific categories of medicinal products in 2010. The presence of CVD was defined by a diagnosis associated with chronic disease status and hospital stays in 2010. RESULTS Among people aged greater or equal to 20years, treatment frequencies were 22% (men 20% vs. women 23%) for antihypertensives, 15% (14% vs. 16%) for lipid-lowering agents and 6% (6% vs. 5%) for antidiabetic medications. These frequencies were, respectively, 33%, 23% and 8% in patients aged greater or equal to 40years and 55%, 38% and 14% in patients aged greater or equal to 60 years. The frequency of at least one treatment for at least one of the three risk factors was 41% in patients aged greater or equal to 40 years and 66% in patients aged greater or equal to 60 years. Among patients aged greater or equal to 20 years, 22% were treated for at least one risk factor in the absence of CVD and 3% were treated for at least one risk factor in the presence of CVD. Regional differences were observed, with higher frequencies of antihypertensive and antidiabetic use in the North, North-East and Overseas regions. Treatment frequencies increased with level of deprivation, especially for antidiabetics. CONCLUSION This national study more clearly defines treatment frequencies and the populations and regions with the highest treatment frequencies.

Abstract
Objective. Study objectives were to assess temporal trends and identify patient- and practice-level predictors of the prescription of antiplatelet medications in a national sample of ischemic stroke (IS) patients seeking ambulatory care. Methods. IS-related outpatient visits by adults were identified using the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey for the years 2000-2007. We assessed prescribing of antiplatelet medications using the generic drug code and drug entry codes in these data. Temporal trends in antiplatelet prescribing were assessed using the Cochran-Mantel-Haenszel test for trend. Results. We identified 9.5 million IS-related ambulatory visits. Antiplatelet medications were prescribed at 35.5% of visits. Physician office prescribing of the clopidogrel-aspirin combination increased significantly from 0.5% in 2000 to 22.0% in 2007 (P = 0.05), whereas prescribing of aspirin decreased from 17.9% to 7.0% (P = 0.50) during the same period. Conclusion. We observed a continued increase in prescription of the aspirin-clopidogrel combination from 2000 to 2007. Clinical trial evidence suggests that the aspirin-clopidogrel combination does not provide any additional benefit compared with clopidogrel alone; however, our study findings indicate that even with lack of adequate clinical evidence physician prescribing of this combination has increased in real-world community settings.

Abstract
Population-based stroke registries can provide valid stroke incidence because they ensure exhaustiveness of case ascertainment. However, their results are difficult to extrapolate because they cover a small population. The French Hospital Discharge Database (FHDDB), which routinely collects administrative data, could be a useful tool for providing data on the nationwide burden of stroke. The aim of our pilot study was to assess the validity of stroke diagnosis reported in the FHDDB. All records of patients with a diagnosis of stroke between 2004 and 2008 were retrieved from the FHDDB of Dijon Teaching Hospital. The Dijon Stroke Registry was considered as the gold standard. The sensitivity, positive predictive value (PPV), and weighted kappa were calculated. The Dijon Stroke Registry identified 811 patients with a stroke, among whom 186 were missed by the FHDDB and thus considered false-negatives. The FHDDB identified 903 patients discharged following a stroke including 625 true-positives confirmed by the registry and 278 false-positives. The overall sensitivity and PPV of the FHDDB for the diagnosis of stroke were, respectively, 77.1 % (95 % CI 74.2–80) and 69.2 % (95 % CI 66.1–72.2). For cardioembolic and lacunar strokes, the FHDDB yielded higher PPVs (respectively 86.7 and 84.6 %; p < 0.0001) than those of other stroke subtypes. The PPV but not sensitivity significantly increased over the years (p < 0.0001). Agreement with the stroke registry was moderate (kappa 52.8; 95 % CI 46.8–58.9). The FHDDB-based stroke diagnosis showed moderate validity compared with the Dijon Stroke Registry as the gold standard. However, its accuracy (PPV) increased with time and was higher for some stroke subtypes.

Abstract
OBJECTIVES To measure intensive care unit (ICU) admission, intubation, decompressive craniotomy, and outcomes at discharge in a large population-based study of children with ischemic and hemorrhagic stroke. METHODS In a retrospective study of all children enrolled in a Northern Californian integrated health care plan (1993-2003), we identified cases of symptomatic childhood stroke (age >28 days through 19 years) from inpatient and outpatient electronic diagnoses and radiology reports, and confirmed them through chart review. Data regarding stroke evaluation, management, and outcomes at discharge were abstracted. Intensive care unit (ICU) admission, intubation, and decompressive neurosurgery rates were measured, and multivariate logistic regression was used to identify predictors of critical care usage and outcomes at discharge. RESULTS Of 256 cases (132 hemorrhagic and 124 ischemic), 61% were admitted to the ICU, 32% were intubated, and 11% were treated with a decompressive neurosurgery. Rates were particularly high among children with hemorrhagic stroke (73% admitted to the ICU, 42% intubated, and 19% received a decompressive neurosurgery). Altered mental status at presentation was the most robust predictor for all 3 measures of critical care utilization. Neurologic deficits at discharge were documented in 57%, and were less common after hemorrhagic than ischemic stroke: 48% vs 66% (odds ratio 0.5, 95% confidence interval 0.3-0.8). Case fatality was 4% overall, 7% among children admitted to the ICU, and was similar between ischemic and hemorrhagic stroke. CONCLUSIONS ICU admission is frequent after childhood stroke and appears to be justified by high rates of intubation and surgical decompression.

Abstract
BACKGROUND The population of Germany is aging, i.e., the elderly currently make up an increasing percentage of the population from year to year. Furthermore, many common chronic diseases mainly affect the elderly. For these two reasons, the overall cost of health care in Germany is expected to increase. We studied the effect that population aging has had on the number of hospitalizations for major types of chronic disease in Germany since the year 2000. METHODS This study is based on nationwide hospitalization statistics, classified by diagnosis, that were published by the German Federal Statistical Office. We analyzed data for three classes of diagnoses--malignant neoplasia, cardiovascular diseases, and diseases of the musculoskeletal system and connective tissue--which were further broken down into nine diagnostic subgroups. Changes in inpatient case numbers might be due either to population aging or to changing rates of hospitalization for individual diagnoses. We used index decomposition analysis to determine the relative influence of these two factors on changing case numbers. RESULTS The author found that the aging of the population increased the number of hospitalizations for all of the diagnoses studied. This was particularly evident with respect to the large birth cohorts born in the 1920s (with the diagnosis of congestive heart failure) and in the period 1934-1944 (with the diagnoses ischemic heart disease, lung cancer, colorectal cancer, and osteoarthritis). On the other hand, changing rates of hospitalization for individual diagnoses increased the number of hospitalizations for some diagnoses (congestive heart failure, diseases of the spine and back) and decreased it for others (ischemic heart disease, cerebrovascular diseases, colorectal cancer, breast cancer). CONCLUSION The aging of the population and the changing rates of hospitalization for various diagnoses are exerting separate effects on the number of hospitalizations for chronic diseases in Germany. Predictions of hospital case numbers in the future must take both factors into account.

Abstract
Background The late 1990s/early 2000s was a time of change in both the prevention and acute care of ischemic stroke, with primary prevention driven by increased utilization of antihypertensive, antiplatelet, anticoagulation, and lipid-lowering agents. Aim To examine whether ischemic stroke hospitalization rates and outcomes in the United States have changed. Method We retrospectively identified 894 169 hospitalizations with a primary diagnosis of ischemic stroke from 1 January 1998 through to 31 December 2007 in the Nationwide Inpatient Sample, the largest all-payer healthcare database in the United States. Annual, national case estimates were combined with US Census data to derive age-adjusted and age-specific population hospitalization rates. Temporal trends were tested using linear regression. Results From 1998 through 2007, there were an estimated 4 382 336 ischemic stroke hospitalizations in the United States. Overall, the age-adjusted rate of ischemic stroke hospitalization decreased from 184 to 128 per 100 000 ( P #< 0.0001). Age-specific rates decreased among those 55+ years old ( P #< 0.0001), but increased among those 25–34 and 35–44 years old ( P #< 0.001 and P #< 0.0001, respectively). Rates among those <25 and 45–54 years old were unchanged. In-hospital mortality decreased from 7.0% (standard error 0.1) to 5.4% (standard error 0.1) ( P #< 0.0001). Case proportion at the highest quintile of hospitals by annual caseload increased from 54.0% (standard error 2.1) to 61.8% (standard error 2.0) ( P #< 0.0001). Mean adjusted hospitalization costs increased from $9273 (standard deviation 199) to $10 524 (standard deviation 77) ( P #< 0.0001). Conclusion In 1998 through to 2007, the overall rate of ischemic stroke hospitalization in the United States decreased. However, rates among young adults increased. In-hospital mortality rates decreased over the study period.

Abstract
BACKGROUND AND PURPOSE The risk of recurrent stroke in the modern era of secondary stroke prevention is not well defined. Several prediction models, including the Stroke Prognostic Instrument-II (SPI-II), have been created to identify patients at highest risk, but their performance in modern populations has been infrequently tested. We aimed to assess the 1-year risk of recurrence after hospital discharge in a recent, large, community-based cohort of patients with ischemic stroke and to validate the SPI-II prediction model in this cohort. METHODS From 2004 through 2006, 5575 patients with acute ischemic stroke were prospectively identified and followed for recurrent events. Kaplan-Meier statistics were used to analyze the cumulative incidence of recurrent ischemic stroke. Harrell c-statistic was calculated to determine the performance of SPI-II in predicting stroke or death at 1 year, and the log-rank test was used to compare the differences among low-, middle-, and high-risk groups. RESULTS Among 5575 patients with ischemic stroke, recurrence was observed in 221 during the subsequent year. Kaplan-Meier estimates of cumulative rates of recurrent stroke were 2.5%, 3.6%, and 4.8% at 3, 6, and 12 months, respectively. Rates of stroke or death for SPI-II in the low-, middle-, and high-risk groups were 8.2%, 24.5%, and 35.6%, respectively (trend, P=0.001). The c-statistic for SPI-II was 0.62 (95% CI, 0.61-0.64). CONCLUSIONS The modern 1-year rate of recurrent stroke after hospital discharge is low but still substantial at 4.8%. SPI-II is a modestly effective tool in identifying patients with ischemic stroke at highest risk of developing recurrence or death.

Abstract
BACKGROUND AND PURPOSE Little is known about sex-specific stroke hospitalization rates among middle-aged individuals. This study assessed recent temporal trends in stroke hospitalizations among persons aged 35 to 64 years in the United States. METHODS The Nationwide Inpatient Sample was used to identify individuals with a primary or secondary discharge diagnosis of stroke between 1997 and 2006 (n=3,161,752). Age-adjusted sex-specific rates of ischemic and hemorrhagic stroke hospitalizations were assessed among individuals aged 35 to 64 years. RESULTS Over the study period, stroke hospitalization rates per 100 000 decreased by 10% from 66.7 to 60.3 (trend P<0.01) in men and 8% from 52.7 to 48.3 (trend P<0.001) in women. The 55- to 64-year age group drove reductions in hospitalization rates: slope (rate of change per year)=-12.3 for men and -8.9 for women (both P<0.001). Rates increased slightly in men and women aged 35 to 44 years and remained stable for persons aged 45 to 54 years. Stroke subtype analysis revealed that rates of ischemic stroke hospitalization increased and hemorrhagic stroke hospitalization remained stable among individuals aged 35 to 44 years. Rates of ischemic and hemorrhagic stroke hospitalizations remained stable among those aged 45 to 54 years and decreased among persons aged 55 to 64 years. CONCLUSIONS From 1997 to 2006, ischemic and hemorrhagic stroke hospitalization rates declined among individuals aged 55 to 64 years and remained stable among persons aged 45 to 54 years; ischemic stroke hospitalization rates increased among individuals aged 35 to 44 years. Further studies are needed to assess and address increases in ischemic stroke hospitalizations among younger individuals.

Abstract
BACKGROUND Advancements in diagnosis and treatment have resulted in better clinical outcomes after stroke; however, the influence of age and gender on recent trends in death during stroke hospitalization has not been specifically investigated. We assessed the impact of age and gender on nationwide patterns of in-hospital mortality after stroke. METHODS Data were obtained from all US states that contributed to the Nationwide Inpatient Sample. All patients admitted to hospitals between 1997 and 1998 (n=1 351 293) and 2005 and 2006 (n=1 202 449), with a discharge diagnosis of stroke (identified by the International Classification of Diseases, Ninth Revision procedure codes), were included. Time trends for in-hospital mortality after stroke were evaluated by gender and age group based on 10-year age increments (<55, 55-64, 65-74, 75-84, >84) using multivariable logistic regression. RESULTS Between 1997 and 2006, in-hospital mortality rates decreased across time in all sub-groups (all P<0·01), except in men >84 years. In unadjusted analysis, men aged >84 years in 1997-1998 had poorer mortality outcomes than similarly aged women (odds ratio 0·93, 95% confidence interval=0·88-0·98). This disparity worsened by 2005-2006 (odds ratio 0·88, 95% confidence interval=0·84-0·93). After adjusting for confounders, compared with similarly aged women, the mortality outcomes among men aged >84 years were poorer in 1997-1998 (odds ratio 0·97, 95% confidence interval=0·92-1·02) and were poorer in 2005-2006 (odds ratio 0·92, 95% confidence interval=0·87-0·96), P=0·04, for gender × time trend. CONCLUSIONS Over the last decade, in-hospital mortality rates after stroke in the United States have declined for every age/gender group, except men aged >84 years. Given the rapidly ageing US population, avenues for boosting in-hospital survival among very elderly men with stroke need to be explored.

Abstract
PURPOSE Acute care utilization patterns are not well described but may help inform care coordination and treatment for pediatric stroke. The Kids Inpatient Database was queried to describe demographics and clinical characteristics of children with stroke, compare acute care utilization for hemorrhagic vs. ischemic stroke and Children's vs. non-Children's Hospitals, and identify factors associated with aggressive care and in-hospital mortality. METHODS Using a retrospective cohort of children hospitalized with stroke, demographics, predisposing conditions, and intensive (mechanical ventilation, advanced monitoring, and blood product administration) or aggressive (pharmacological therapy and/or invasive interventions) care were compared by stroke and hospital types. Factors associated with aggressive care or in-hospital mortality were explored using logistic regression. RESULTS Hemorrhagic stroke comprised 43% of stroke discharges, was more common in younger children, and carried greater mortality. Ischemic stroke was more common in older children and more frequently associated with a predisposing condition. Rates of intensive and aggressive care were low (30% and 15%), similar by stroke type, and greater at Children's Hospitals. Older age, hemorrhagic stroke, predisposing condition, and treatment at a Children's Hospital were associated with aggressive care. Hemorrhagic stroke and aggressive care were associated with in-hospital mortality. CONCLUSIONS Acute care utilization is similar by stroke type but both intensive and aggressive care are more common at Children's Hospitals. Mortality remains relatively high after pediatric stroke. Widespread implementation of treatment guidelines improved outcomes in adult stroke. Adoption of recently published treatment recommendations for pediatric stroke may help standardize care and improve outcomes.

Abstract
BACKGROUND Multiple risk factor interventions using counselling and educational methods assumed to be efficacious and cost-effective in reducing coronary heart disease (CHD) mortality and morbidity and that they should be expanded. Trials examining risk factor changes have cast doubt on the effectiveness of these interventions. OBJECTIVES To assess the effects of multiple risk factor interventions for reducing total mortality, fatal and non-fatal events from CHD and cardiovascular risk factors among adults assumed to be without prior clinical evidence CHD.. SEARCH STRATEGY We updated the original search BY SEARCHING CENTRAL (2006, Issue 2), MEDLINE (2000 to June 2006) and EMBASE (1998 to June 2006), and checking bibliographies. SELECTION CRITERIA Randomised controlled trials of more than six months duration using counselling or education to modify more than one cardiovascular risk factor in adults from general populations, occupational groups or specific risk factors (i.e. diabetes, hypertension, hyperlipidaemia, obesity). DATA COLLECTION AND ANALYSIS Two authors extracted data independently. We expressed categorical variables as odds ratios (OR) with 95% confidence intervals (CI). Where studies published subsequent follow-up data on mortality and event rates, we updated these data. MAIN RESULTS We found 55 trials (163,471 participants) with a median duration of 12 month follow up. Fourteen trials (139,256 participants) with reported clinical event endpoints, the pooled ORs for total and CHD mortality were 1.00 (95% CI 0.96 to 1.05) and 0.99 (95% CI 0.92 to 1.07), respectively. Total mortality and combined fatal and non-fatal cardiovascular events showed benefits from intervention when confined to trials involving people with hypertension (16 trials) and diabetes (5 trials): OR 0.78 (95% CI 0.68 to 0.89) and OR 0.71 (95% CI 0.61 to 0.83), respectively. Net changes (weighted mean differences) in systolic and diastolic blood pressure (53 trials) and blood cholesterol (50 trials) were -2.71 mmHg (95% CI -3.49 to -1.93), -2.13 mmHg (95% CI -2.67 to -1.58 ) and -0.24 mmol/l (95% CI -0.32 to -0.16), respectively. The OR for reduction in smoking prevalence (20 trials) was 0.87 (95% CI 0.75 to 1.00). Marked heterogeneity (I(2) > 85%) for all risk factor analyses was not explained by co-morbidities, allocation concealment, use of antihypertensive or cholesterol-lowering drugs, or by age of trial. AUTHORS' CONCLUSIONS Interventions using counselling and education aimed at behaviour change do not reduce total or CHD mortality or clinical events in general populations but may be effective in reducing mortality in high-risk hypertensive and diabetic populations. Risk factor declines were modest but owing to marked unexplained heterogeneity between trials, the pooled estimates are of dubious validity. Evidence suggests that health promotion interventions have limited use in general populations.

Abstract
Mounting regional and national evidence suggests a decline in primary in-hospital stroke diagnoses. However, these data do not include secondary diagnoses of stroke, and little is known about whether this decline varies significantly by sex. Compared with men, women are less likely to have optimal control of stroke risk factors, which may be leading to less impressive declines in stroke incidence in women. This study evaluated sex trends in hospital-based stroke diagnoses in the United States. The study was a time-trend analysis by sex of national age-adjusted rates of primary or secondary hospital-based stroke diagnosis per 100,000 persons (identified by ICD-9 procedure codes) among patients for 1997-2006 using data from all US states contributing to the Nationwide Inpatient Sample. Adjustments were made to correct for some inaccuracies in diagnostic codes. Between 1997 and 2006, total hospital-based stroke diagnoses decreased from 680,607 to 609,359. The age-adjusted hospital-based stroke diagnosis rate per 100,000 persons decreased in a roughly linear pattern from 282.7 to 210.4 in men (26%; P < .001) and from 240.5 to 184.7 in women (23%; P < .05). The average rate of decrease (slope) in hospital-based stroke diagnosis rates was greater in men than in women (-8.7 vs -7.5 per 100,000 persons; P = .003). Age-adjusted rates of hospital-based stroke diagnoses have decreased substantially in the United States during the last decade, but slightly less so in women. These results are generally encouraging, but nonetheless indicate that more intensive preventive efforts are warranted to completely eliminate sex disparities in stroke occurrence.

Abstract
BACKGROUND Stroke results in substantial death and disability. To address this burden, Get With The Guideline (GWTG)-Stroke was developed to facilitate the measurement, tracking, and improvement in quality of care and outcomes for acute stroke and transient ischemic attack (TIA) patients in the United States. METHODS AND RESULTS We analyzed the characteristics, performance measures, and in-hospital outcomes in the first 1 000 000 acute ischemic stroke, intracerebral hemorrhage, subarachnoid hemorrhage, and TIA admissions from 1392 hospitals that participated in the GWTG-Stroke Program 2003 to 2009. Patients were 53.5% women, 73.3% white, and with mean age of 70.1+/-14.9 years. There were 601 599 (60.2%) ischemic strokes, 108 671 (10.9%) intracerebral hemorrhages, 34 945 (3.5%) subarachnoid hemorrhages, 26 977 (2.7%) strokes not classified, and 227 788 (22.8%) TIAs. Performance measures showed small to moderate differences by cerebrovascular event type. In-hospital mortality rate was highest among intracerebral hemorrhage (25.0%) and subarachnoid hemorrhage (20.4%), and intermediate in ischemic stroke (5.5%) patients and lowest among TIA patients (0.3%). Significant improvements over time from 2003 to 2009 in quality of care were observed: all-or-none measure, 44.0% versus 84.3% (+40.3%, P<0.0001). After adjustment for patient and hospital variables, the cumulative adjusted odds ratio for the all-or-none measure over the 6 years was 9.4 (95% confidence interval, 8.3 to 10.6, P<0.0001). Temporal improvements in length of stay and risk-adjusted in-hospital mortality rate (for ischemic stroke and TIA) were also observed. CONCLUSIONS With more than 1 million patients enrolled, GWTG-Stroke represents an integrated stroke and TIA registry that supports national surveillance, innovative research, and sustained quality improvement efforts facilitating evidence-based stroke/TIA care.

Abstract
BACKGROUND Temporal trends in stroke incidence are unclear. We aimed to examine age- and sex-specific temporal trends in incidence of fatal and nonfatal hospitalized stroke in Scotland from 1986 to 2005. METHODS AND RESULTS Mean age at the time of first stroke was 70.8 (SD, 12.9) years in men and 76.4 (12.9) years in women. Between 1986 and 2005, rates fell in men from 235 (95% CI, 229 to 242) to 149 (144 to 154) and in women from 299 (292 to 306) to 182 (177 to 188). Poisson modeling showed that temporal trends were influenced by age with declines in incidence of hospitalized stroke starting later in younger than older age groups. In both men and women aged under 55 years, the overall incidence rate of stroke was significantly higher in 2005 than in 1986. CONCLUSIONS We report in a whole country that the overall incidence of stroke declined steadily and substantially between 1986 and 2005, with a relative reduction in the risk of stroke of 31% in men and 42% in women. Reductions in rates of both hospitalized and nonhospitalized fatal stroke contributed to this overall decline. The increase in incident stroke rates in young people is of concern.

Abstract
Background and Purpose—
The aim of this study was to examine the effect of sex across different age groups and over time for stroke incidence, 30-day case-fatality, and mortality.
Methods—
All first hospitalizations for stroke in Scotland (1986 to 2005) were identified using linked morbidity and mortality data. Age-specific rate ratios (RRs) for comparing women with men for both incidence and mortality were modeled with adjustment for study year and socioeconomic deprivation. Logistic regression was used to model 30-day case-fatality.
Results—
Women had a lower incidence of first hospitalization than men and size of effect varied with age (55 to 64 years, RR=0.65, 95% CI 0.63 to 0.66; ≥85 years, RR=0.94, 95% CI 0.91 to 0.96). Women aged 55 to 84 years had lower mortality than men and again size of effect varied with age (65 to 74 years, RR=0.79, 95% CI 0.76 to 0.81); 75 to 84 years, RR=0.94, 95% CI 0.92 to 0.95). Conversely, women aged ≥85 years had 15% higher stroke mortality than men (RR=1.15, 95% CI 1.12 to 1.18). Adjusted risk of death within 30 days was significantly higher in women than men, and this difference increased over the 20-year period in all age groups (adjusted OR in 55 to 64 year olds 1.23, 95% CI 1.14 to 1.33 in 1986 and 1.51, 95% CI 1.39 to 1.63 in 2005).
Conclusions—
We observed lower rates of incidence and mortality in younger women than men. However, higher numbers of older women in the population mean that the absolute burden of stroke is greater in women. Short-term case-fatality is greater in women of all ages and, worryingly, these differences have increased from 1986 to 2005.
