BACKGROUND AND OBJECTIVE: Intracerebral hemorrhage (ICH) is a serious medical condition with high mortality. However, factors leading to long-term mortality after ICH are largely unclear. The aim of this community-based study is to assess predictors of long-term mortality after spontaneous ICH. METHODS: We identified all patients admitted with spontaneous ICH to hospitals with a certified stroke unit in Brno, the second largest city in the Czech Republic (CR), in 2011, the year of the Czech Population and Housing Census. We reviewed their medical records for risk factors, radiographic parameters, and measures of post-stroke neurological deficit [National Institutes of Health Stroke Scale (NIHSS)]. Using the dates of death from the Czech National Mortality Register, we calculated mortality at 30 days, six months, one year, and three years after the ICH. Multivariate analysis with forward stepwise logistic regression was performed to determine independent predictors of mortality (p < 0.05). RESULTS: In 2011, 1086 patients with stroke were admitted to the four stroke-certified hospitals in Brno, CR. Of these, 134 had spontaneous ICH, with complete data available in 93 of them entering the final analysis. The mortality at 30 days, 6 months, 1 year, and 3 years post-ICH was 34%, 47%, 51%, and 63%, respectively. The mortality was highest in the first few days post-event, with 50% of patients dying in 255 days and average survival being 884 ± 90 days. Both NIHSS and modified ICH (MICH) score showed to be strong and reliable predictors of short- as well as long-term mortality; the risk of death post-ICH increased with older age and size of ICH. Other risk factors contributing to higher, primarily shorter-term mortality included history of cardiac failure, myocardial infarction, or atrial fibrillation. CONCLUSIONS: In our community-based study, we found that severity of neurological deficit at admission (NIHSS), combined with age and size of ICH, well predicted short- as well as long-term mortality after spontaneous ICH. A history of cardiac failure, myocardial infarction, or atrial fibrillation at presentation were also predictors of mortality, underscoring the need for optimal cardiac management in patients with ICH.

BACKGROUND AND PURPOSE: During the coronavirus disease 2019 (COVID-19) pandemic many countries reported a decline in stroke volumes. The aim of this study was to analyze if the decline was related to the intensity of the COVID-19 pandemic. METHODS: The first pandemic year (1 March 2020 to 28 February 2021) overall and during the three COVID-19 waves were compared with the preceding year. Volumes of acute ischaemic stroke (AIS), subarachnoid hemorrhage, intracerebral hemorrhage and recanalization treatments (intravenous thrombolysis [IVT] and mechanical thrombectomy [MT]) were obtained from the National Register of Reimbursed Health Services. Door-to-needle time, onset-to-door time and National Institutes of Health Stroke Scale at admission were obtained from the Registry of Stroke Care Quality. RESULTS: During the pandemic year compared to the preceding year there were 26,453 versus 28,771 stroke admissions, representing an 8.8% decline (p < 0.001). The declines (-10%, -11%, -19%) appeared in COVID-19 waves (spring 2020, autumn 2020, winter 2021) except for an increase (2%) during summer 2020. Admissions for AIS declined by 10.2% (p < 0.001), whilst hemorrhagic stroke volumes were minimally decreased. The absolute volumes of IVT and MT decreased by 9.4% (p < 0.001) and 5.7% (p = 0.16), respectively. However, the proportions of ischaemic stroke patients receiving IVT (18% vs. 18%; p = 0.72) and MT (6% vs. 6%; p = 0.28) remained unchanged. CONCLUSIONS: There was a decline in stroke admissions, but such decline was not related to COVID-19 incidence. The frequency of use of recanalization procedures (IVT, MT) and times (onset-to-door time, door-to-needle time) in AIS were preserved in the Czech Republic during the first year of the pandemic.

BACKGROUND AND OBJECTIVE: Short- and long-term mortality following ischemic stroke (IS) and their predictors have not been defined in the Czech population, and studies on long-term mortality are largely missing for the populations of Central Europe. METHODS: Using the National Register of Hospitalized Patients and the Czech National Mortality Registry, we analyzed data on 1-month, 1-year, and 3-year all-cause mortality for patients admitted with IS to any of the 4 hospitals with a certified stroke unit in Brno, Czech Republic, in 2011. We reviewed discharge summaries and recorded potential factors impacting mortality after the index stroke event. Using univariate and multivariable analyses, we identified predictors of mortality at all 3 time points. RESULTS: In our multivariable model, statin use (odds ratio [OR] 0.095, p < 0.0001), age at stroke (OR 1.03, p = 0.0445), and admission National Institutes of Health Stroke Scale (NIHSS) score (OR 1.16, p < 0.0001) predicted 1-month mortality, while statin use (OR 0.43, p = 0.0004), history of cardiac failure (OR 2.17, p = 0.0137), age at stroke (OR 1.07, p < 0.0001), and admission NIHSS score (OR 1.14, p < 0.0001) predicted 1-year mortality. Statin use (OR 0.54, p = 0.0051), history of cardiac failure (OR 2.13, p = 0.0206), age at stroke (OR 1.07, p < 0.0001), and admission NIHSS score (OR 1.11, p < 0.0001) also predicted 3-year mortality. CONCLUSIONS: Our study is the first to report data on short- and long-term mortality rates and their predictors in patients hospitalized with IS in the Czech population. Our results indicate that mortality rates and predictors of mortality are consistent with those reported in studies from other populations throughout the world.

INTRODUCTION: During the COVID-19 pandemic, studies reported less number of hospitalizations for acute stroke and reduction in the use of recanalization treatments. This study analyzes nationwide data on stroke admissions and management in the Czech Republic during the first wave of the COVID-19 pandemic. METHODS: We compared the early COVID-19 pandemic (March-May 2020) with the pre-pandemic period (January-February 2020 and March-May 2019): (a) the National Register of Reimbursed Health Services provided volume of all admissions for subarachnoid hemorrhage (SAH), intracerebral hemorrhage (ICH), and ischemic stroke (IS), and volume of recanalization treatments (intravenous thrombolysis [IVT] and mechanical thrombectomy [MT]); (b) Registry of Stroke Care Quality provided door-to-needle time (DNT), onset-to-door time (ODT), and stroke severity at admission (National Institutes of Health Stroke Scale, NIHSS) for IS. RESULTS: During the pandemic (March-May 2020), the peak number of COVID-19 patients treated in Czech hospitals was 39 per million. In March-May 2020 versus March-May 2019, hospital admissions decreased as follows: stroke overall by 14% (p < 0.001), IS by 14% (p < 0.001), SAH by 15% (p = 0.07), and ICH by 7% (p = 0.17). The mean age was 74 years versus 74 years (p = 0.33), and 52% versus 51% were men (p = 0.34). The volumes of IVT and MT decreased by 14% (p = 0.001) and 19% (p = 0.01), respectively. The proportions of all IS patients receiving IVT or MT remained unchanged, with, respectively, 17% versus 17% receiving IVT (p = 0.86) and 5% versus 5% receiving MT (p = 0.48). DNT and ODT were 24 versus 25 min (p = 0.58) and 168 versus 156 min (p = 0.23), respectively. NIHSS at admission did not differ (6 vs. 6; p = 0.54). CONCLUSION: Even with a low burden of COVID-19 during the first wave and no change in organization and logistics of stroke services, stroke admissions and volume of recanalization treatments decreased. Public health communication campaigns should encourage people to seek emergency medical care for stroke symptoms during the COVID-19 pandemic.

BACKGROUND: This retrospective cross-sectional study reports 1 month and 1 year intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH) case fatality rates and their temporal trends in the Czech Republic between 1998 and 2015. METHODS: Utilizing the National Register of Hospitalized Patients, we randomly selected 600 patients hospitalized for ICH and 600 patients hospitalized for SAH for each year from 1998 to 2015, and identified those who died, regardless of cause, using the Czech National Mortality Registry. We calculated crude and age-adjusted 1 month and 1 year case fatality rates for ICH and SAH. Long-term trends of the crude rates were analyzed using a one-sided Cochran Armitage test. RESULTS: A total of 21,600 cases hospitalized for SAH and ICH (10,800 for each) between 1998 and 2015 were randomly selected for analysis. One month case fatality of SAH overall and in women has decreased by 0.2% (P = .006) and 0.3% per year (P = .04), respectively. Overall 1 year case fatality of SAH has decreased by 0.2% per year (P = .03). One month case fatality rate of ICH overall and in men has decreased by 0.2% (p=0.01) and 0.4% (P = .0007), respectively. One year case fatality of ICH in men has decreased by 0.2% per year (P = .047). CONCLUSIONS: One month and 1 year case fatality rates for SAH and ICH have been decreasing in the Czech Republic between 1998 and 2015, and are similar or lower than those reported from other developed European countries.

BACKGROUND: Contemporary stroke incidence data are not available in some countries and regions, including in Eastern Europe. Based on previous validation of the accuracy of the National Registry of Hospitalized Patients (NRHOSP), we report the incidence of hospitalized stroke in the Czech Republic (CR) using the NRHOSP. METHODS: The results of the prior validation study assessing the accuracy of coding of stroke diagnoses in the NRHOSP were applied, and we calculated (1) the overall incidence of hospitalized stroke and (2) the incidence rates of hospitalized stroke for the three main stroke types: cerebral infarction (International Classification of Diseases Tenth Revision, CI I63), subarachnoid hemorrhage (SAH I60), and intracerebral hemorrhage (ICH I61). We calculated the average annual age- and sex-standardized incidence. RESULTS: The overall incidence of hospitalized stroke was 241 out of 100,000 individuals. The incidence of hospitalized stroke for the main stroke types was 8.2 cases in SAH, 29.5 in ICH, and 211 in CI per 100,000 individuals. The standardized annual stroke incidence adjusted to the 2000 World Health Organization population for overall stroke incidence of hospitalized stroke was 131 per 100,000 individuals. Standardized stroke incidence for stroke subtypes was 5.7 cases in SAH, 16.7 in ICH, and 113 in CI per 100,000 individuals. CONCLUSIONS: These studies provide an initial assessment of the burden of stroke in this part of the world. The estimates of hospitalized stroke in the CR and Eastern Europe suggest that ICH is about three times more common than SAH, and hemorrhagic stroke makes up about 18% of strokes.

BACKGROUND AND PURPOSE: Administration of evidence-based pharmacotherapy improves stroke outcome while the use of non-evidence-based medications may not be of benefit and leads to unnecessary patient care costs. The aim of our study was to determine the frequency of guideline-approved and guideline-disapproved pharmacotherapy use in acute stroke management in the Czech Republic (CR). METHODS: Using the ICD-10 codes, 500 stroke and transient ischemic attack (TIA) patients were randomly selected (random selection of 10 hospitals and then 50 patients from each hospital) from the National Registry of Hospitalized Patients for strokes occurring in 2011. Discharge summaries were reviewed for medications prescribed during hospitalization and at discharge. RESULTS: Of the 500 requested discharge summaries, 484 were available for review (response rate 97%). Up to 479 (96%) summaries were sufficient for evaluation and of these, 393 were confirmed to have a stroke or TIA diagnosis. Brain imaging (computed tomography or magnetic resonance imaging) was performed in 97% of the 393 cases. Intravenous thrombolysis was administered to 7% of patients with ischemic stroke (rate was 0%-25% in different hospitals). Up to 97% of patients with ischemic events (TIA or ischemic stroke) were treated with antiplatelets or anticoagulants. At least 1 non-evidence-based medication was administered to 28% of the 393 patients (rate was 5%-89% in different hospitals). CONCLUSIONS: Guideline-disapproved pharmacotherapy is common in stroke and TIA patients in the CR and processes should be put into place to lessen the frequency of their use. The use of guideline-approved medications is also high and should be further promoted.

BACKGROUND AND PURPOSE: Seizures are a known complication of ischemic stroke (IS). This study assesses the long-term incidence and characteristics of poststroke seizures in a well-defined population. METHODS: Using the Rochester Epidemiology Project medical records-linkage system, we identified all incident cases of IS among Rochester, Minnesota, residents from 1990 to 1994 and followed the patients in the comprehensive medical record through March 2014. All patients with poststroke seizures were identified, and data regarding incident IS, seizures, and status at last follow-up were analyzed. RESULTS: We identified 489 patients with first IS. Mean follow-up was 6.5 (standard deviation 6.3) years. New onset seizures occurred in 35 patients (7.2%). Patients with poststroke seizure did not differ from those without in terms of IS etiologic subtype (P = .44) or IS risk factors (P > .05). Early seizures (within 14 days of index stroke) developed in 14 patients (40%), the majority within the first 24 hours (n = 9, 64.3%). The median time of seizure onset for the remaining 21 patients was 13.8 months. Functional outcome, as measured by modified Rankin Scale (mRS), was worse following development of poststroke seizures (mean mRS score 2.9 after IS, 3.3 following index seizure; P = .005), and mortality was higher as well, even after adjusting for IS etiologic subtype (HR 1.52, 95% confidence interval 1.07-2.16, P = .02). CONCLUSION: Development of poststroke seizures is an infrequent but significant complication of IS, portending a worse short-term functional outcome and a higher long-term mortality rate. Seizure occurrence did not differ based on IS etiologic subtype or stroke risk factors.

BACKGROUND: Stroke is a common cause of mortality and morbidity in Eastern Europe. However, detailed epidemiological data are not available. The National Registry of Hospitalized Patients (NRHOSP) is a nationwide registry of prospectively collected data regarding each hospitalization in the Czech Republic since 1998. As a first step in the evaluation of stroke epidemiology in the Czech Republic, we validated stroke cases in NRHOSP. METHODS: Any hospital in the Czech Republic with a sufficient number of cases was included. We randomly selected 10 of all 72 hospitals and then 50 patients from each hospital in 2011 stratified according to stroke diagnosis (International Classification of Diseases Tenth Revision [ICD-10] cerebrovascular codes I60, I61, I63, I64, and G45). Discharge summaries from hospitalization were reviewed independently by 2 reviewers and compared with NRHOSP for accuracy of discharge diagnosis. Any disagreements were adjudicated by a third reviewer. RESULTS: Of 500 requested discharge summaries, 484 (97%) were available. Validators confirmed diagnosis in NRHOSP as follows: transient ischemic attack (TIA) or any stroke type in 82% (95% confidence interval [CI], 79-86), any stroke type in 85% (95% CI, 81-88), I63/cerebral infarction in 82% (95% CI, 74-89), I60/subarachnoid hemorrhage in 91% (95% CI, 85-97), I61/intracerebral hemorrhage in 91% (95% CI, 85-96), and G45/TIA in 49% (95% CI, 39-58). The most important reason for disagreement was use of I64/stroke, not specified for patients with I63. CONCLUSIONS: The accuracy of coding of the stroke ICD-10 codes for subarachnoid hemorrhage (I60) and intracerebral hemorrhage (I61) included in a Czech Republic national registry was high. The accuracy of coding for I63/cerebral infarction was somewhat lower than for ICH and SAH.
