Predictors of functional outcome after stroke: Sex differences in older individuals.

Sex differences in stroke are well documented, with females being older at onset, with more severe strokes and worse outcomes than males. Females receive less comprehensive stroke unit treatment. Similarly, older individuals receive poorer quality care than younger ones. There is limited research on sex differences in factors that impact 3-month poststroke functional outcome in people older than 80 years. This register-based and cross-sectional study analyzed data from two stroke quality registers in Sweden from 2014 through 2019. The study included patients aged ≥80 with a diagnosis of ischemic or hemorrhagic stroke. Sociodemographic features, prestroke condition, stroke severity on admission (National Institutes of Health Stroke Scale [NIHSS]), stroke unit care, rehabilitation plans, and 3-month poststroke functional outcome measured with the modified Rankin Scale were analyzed. Ordinal regression analyses stratified by sex were conducted to assess sex differences in factors that impact poststroke functional outcome 3 months after the stroke. A total of 2245 patients were studied with the majority (59.2%) being females. Females experienced more severe strokes (NIHSS median 4 vs. 3, p = 0.01) and were older at stroke onset than males (87.0 vs. 85.4, p < 0.001). Females were also less independent prestroke (69.9% vs. 77.4%, p < 0.001) and a higher proportion of females lived alone (78.2% vs. 44.2%, p < 0.001). Males received intravenous thrombolysis more often than females (16.3% vs. 12.0%, p = 0.005). Regarding 3-month functional outcome, males benefited more from thrombolysis (odds ratio [OR] 0.52, 95% confidence interval [CI] 0.30-0.83), whereas females benefited more from thrombectomy (OR 0.40, 95% CI 0.20-0.71). Stroke care should be adapted to sex disparities in older individuals, while clinicians should be aware of these sex disparities. Further research could clarify the mechanisms behind these disparities and lead to a more personalized approach to stroke care of the older population.

Predictors for Adherence to Recommended Anticoagulation after Stroke Unit Discharge in Patients with Atrial Fibrillation

Introduction: Non-adherence to recommended secondary preventive anticoagulation in stroke patients with atrial fibrillation (AF) is a common phenomenon, although the introduction of direct oral anticoagulants (DOACs) has simplified anticoagulation management for physicians as well as for patients. Methods: We examined the adherence of secondary preventive anticoagulation in AF patients after re-integration in their social environment 6–12 weeks after stroke unit and rehabilitation clinic treatment and analyzed for predictors for adherence and non-adherence. We conducted a telephone survey in consecutive patients treated between January 2013 and December 2021 at our institutional stroke unit with an acute cerebrovascular ischemic event, and we analyzed discharge letters of rehabilitation clinics of those patients not anticoagulated at follow-up. All patients had known or newly diagnosed AF, and in all, we had recommended secondary preventive anticoagulation. Results: Follow-up information about anticoagulant intake could be obtained in 1,348 of 1,685 patients (80.0%) treated within the study period. Anticoagulation rate was 91.5%, with 83.6% of patients receiving DOACs and 7.9% receiving vitamin K antagonists (VKAs). Adherence to recommended anticoagulation was associated with intake of the recommended anticoagulant already at discharge (adjusted odds ratio [OR], 18.357; confidence interval [CI], 9.637–34.969), recommendation of a specific DOAC and dose (in contrast to “DOAC” as drug category) (adjusted OR, 2.971; CI, 1.173–7.255), a lower modified Rankin Scale at discharge (per point; adjusted OR, 0.813; CI, 0.663–0.996), younger age (per year; OR, 0.951; CI, 0.926–0.976), and the absence of peripheral vascular disease (adjusted OR, 0.359; CI, 0.173–0.746). In patients already anticoagulated at discharge, adherence was 98.5%, irrespective of a patient’s age, functional deficit at discharge, and peripheral vascular disease. Avoidable obstacles for non-adherence in patients not on anticoagulants at stroke unit discharge were (1) non-implementation of recommended anticoagulation by rehabilitation physicians predominantly in patients with moderate-severe or severe stroke disability (2.1%), (2) delegation of anticoagulation start from rehabilitation physicians to general practitioners/resident radiologists (1.3%), and (3) rejection of recommended anticoagulation because of patients’ severe stroke disability (0.5%). Non-avoidable obstacles were contraindications to anticoagulation (2.1%) and patients’ refusal (0.7%). Conclusions: Commencing drug administration already during stroke unit hospitalization and providing an explanation for the selection of the recommended anticoagulant in discharge letters ensures high adherence at patients’ re-integration in their social environment after acute stroke treatment. If drug administration cannot be commenced before discharge, education of rehabilitation physicians by stroke physicians and the involvement of stroke physicians into the post-stroke decision process might hinder avoidable obstacles.

Results of Germany's health system performance assessment (HSPA) pilot: the example of stroke care

Abstract Background HSPA is a tool to monitor, evaluate, and improve health systems based on their achievements within different dimensions, e.g., access to care, quality, and population health. Next to the overall system, HSPA also allows to analyze its performance for specific groups across dimensions. In a pilot for a German HSPA, a conceptual framework was developed, and indicators for every dimension were selected and analyzed. This presentation illustrates the results of the German HSPA pilot using the example of access to and quality of care for ischemic stroke. Methods Selected indicators include stroke unit (SU) density, availability of a SU within 30 minutes by car, share of inpatient cases treated in a hospital with a SU, and inpatient mortality from 2014 to 2020, respectively. Indicators were analyzed based on nation-wide hospital discharge data. Travel time was computed and provided by the Federal Institute for Research on Building, Urban Affairs and Spatial Development. Results About 475 SU were identified in hospital data (2014: 463), compared to 350 certified SU in Germany. In 75% of Germany's 11,000 municipalities, 100% of the population could reach a SU within 30 minutes by car. Number of inpatient ischemic stroke cases was about 250,000 per year. Of the 215,000 cases without transfer from another hospital, 93% were treated in a hospital with a SU in 2020 (2014: 88%). Inpatient mortality was about 6,4% for all ischemic stroke cases and 6,1% for cases without transfer, varying only slightly over time. SU treatment showed large, and inpatient mortality minor regional variation. Conclusions Access to and quality of inpatient stroke care seems comparatively good in Germany, as SU density is high and mortality low in the European context. However, regional variation should be further tackled. The example shows how HSPA can be used to assess different strands of care by connecting health system dimensions, to produce actionable evidence for policy. Key messages • Health system performance assessment (HSPA) is a tool for the evaluation and improvement of the overall system but also of the care for specific groups or diseases across health system dimensions. • The results of the German HSPA pilot show a good access and quality for the case of inpatient stroke care. Regional variations might be further reduced via improvements in hospital planning.

Prehospital Stroke Care Part 2: On-Scene Evaluation and Management by Emergency Medical Services Practitioners.

The prehospital phase is a critical component of delivering high-quality acute stroke care. This topical review discusses the current state of prehospital acute stroke screening and transport, as well as new and emerging advances in prehospital diagnosis and treatment of acute stroke. Topics include prehospital stroke screening, stroke severity screening, emerging technologies to aid in the identification and diagnosis of acute stroke in the prehospital setting, prenotification of receiving emergency departments, decision support for destination determination, and the capabilities and opportunities for prehospital stroke treatment in mobile stroke units. Further evidence-based guideline development and implementation of new technologies are critical for ongoing improvements in prehospital stroke care.

Abstract WP78: Low Cost Stroke Management Strategy With Hospital Outcome And One Year Follow-up From A Single Stroke Center, India

Introduction: Stroke is a leading cause of economic burden in the Low Middle Income countries (LMIC’s). We want to study the outcome of acute strokes treated under Government scheme with minimal package (For Ischemic Stroke - 257 USD &amp; For hemorrhagic stroke - 399 USD), but offered evidence-based stroke care other than thrombolysis. Methods: From January 2021 to March 2021, a total of 350 cases were treated in our Ankineedu stroke center. Out of these 125 (36%) acute stroke patients are treated under subsidized economical stroke care from admission to discharge. In-patient mortality, 3 months follow up and 1 year follow up recorded. All patients received standard medical treatment in Stroke unit with Antiplatelets, statins, DVT prophylaxis, Antihypertensives, dysphagia assessment, physiotherapy and Neurosurgery when required. All basic stroke investigations done - CT scan, MRI scan, MR Angio, Neck vessel doppler, Lipids, Renal Function test, RBS, ECG and ECHO. All patients discharged on secondary prevention. Average length of stay is 10 days. Results: There were 94 men and 31 women, age ranged from 18 years to 85 years (median 55 yrs). Type of stroke: Ischemic Stroke -74% and Haemorrhagic stroke - 26%, 4 patients (3.2%) underwent Neurosurgery. Risk factors: Hypertension - 82 (66%), Diabetes - 45 (36%), Cardiac problems - 17 (13.6%), Smoking - 20 (16%), Alcohol - 15 (12%). Total In-house mortality 5 (4%) and the remaining patients outcome at 3 months - Good outcome with modified rankin scale (mRS) 0-2 in 83 patients (66%), Fair Outcome with mRS (3-4) - 35 (28%), 1 patient (0.8%) bedridden and 1 patient (0.8%) died at home. Out of 125 patients, 60 patients (48%) came for 1 year follow up, of these 88% had mRS (0-2), 12% had mRS (3-5). Conclusion: In resource poor countries we can offer basic stroke care model to all needy patients with reasonable outcome. However, the follow up needs to be strengthened.

Moving from traditional to more advanced treatments in stroke care is cost-effective: A case study from Greece

ObjectivesStroke is the most common cause of disability in high-income countries. Several countries offer a limited range of advanced treatments with implications for outcomes, disability and costs. This study estimates the burden of disability that could have been avoided through the transition from traditional (no intravenous thrombolytic therapy (IVT), or endovascular thrombectomy (EVT)) to modern stroke treatments (treatment in stroke units, IVT and EVT). We perform a cost-effectiveness analysis comparing best practice with traditional stroke care, using Greece as a case study. Materials and methodsA Markov model was used to calculate costs and Quality Adjusted Life Years (QALYs) for each treatment strategy, using a lifetime horizon. Data for model inputs were derived from meta-analyses of trials, and national and international cost databases. Sensitivity analyses were also performed to address potential uncertainty and test the robustness of the findings. ResultsIncremental effectiveness comprised 0.22 QALYs per patient and year. Best practice was cost-effective for more than 90% of all iterations (ICER for the baseline scenario: €2,109.25/QALY). Sensitivity analysis demonstrated that the findings remain robust. Considering the stroke incidence in Greece, the annual additional cost to implement best practice was calculated to be between 0.07%-0.15% of the total health expenditure. ConclusionBest practice stroke treatment was cost-effective and affordable in a case study based on Greece. The results could be leveraged by including effects of preventive policies and rehabilitation. They also highlight the importance of adopting modern treatment strategies from a cost-effectiveness perspective, apart from the improved clinical outcomes.

Long-term outcomes of stroke unit care in older stroke patients: a retrospective cohort study.

older patients are less frequently treated in stroke units (SUs). Clinicians do not seem convinced that older patients benefit from specialised treatment in SU similarly to younger patients. our study aimed to compare older patients' long-term outcomes with and without SU treatment. this study used routinely collected health data of 232,447 patients admitted to hospitals in Germany between 2007 and 2017 who were diagnosed with ischaemic stroke (ICD 10 I63). The sample included 29,885 patients aged ≥90years. The outcomes analysed were 10-, 30- and 90-day, and 1-, 3- and 5-year mortality and the combinations of death or recurrence, inpatient treatment and increase in long-term care needs. Bivariate chi-square tests and multivariable logistic regression analyses were used, adjusting for the covariates age, sex, co-morbidity, long-term care needs before stroke and socioeconomic status of the patients' region of origin. between 2007 and 2017, 57.1% of patients aged <90years and 49.6% of those aged ≥90years were treated in a SU. The 1-year mortality rate of ≥90-year-olds was 56.9 and 61.9% with and without SU treatment, respectively. The multivariable-adjusted risk of death in ≥90-year-olds with SU treatment was odds ratio (OR) = 0.67 (95% confidence interval [CI] = 0.62-0.73) 10days after the initial event and OR = 0.76 (95% CI = 0.71-0.82) 3years after stroke. even very old patients with stroke benefit from SU treatment in the short and long term. Therefore, SU treatment should be the norm even in older patients.

Cost-Effectiveness of Mobile Stroke Unit Care in Norway.

Background:Acute ischemic stroke treatment in mobile stroke units (MSUs) reduces time-to-treatment and increases thrombolytic rates, but implementation requires substantial investments. We wanted to explore the cost-effectiveness of MSU care incorporating novel efficacy data from the Norwegian MSU study, Treat-NASPP (the Norwegian Acute Stroke Prehospital Project).Methods:We developed a Markov model linking improvements in time-to-treatment and thrombolytic rates delivered by treatment in an MSU to functional outcomes for the patients in a lifetime perspective. We estimated incremental costs, health benefits, and cost-effectiveness of MSU care as compared with conventional care. In addition, we estimated a minimal MSU utilization level for the intervention to be cost-effective in the publicly funded health care system in Norway.Results:MSU care was associated with an expected quality-adjusted life-year-gain of 0.065 per patient, compared with standard care. Our analysis suggests that about 260 patients with ischemic stroke need to be treated with MSU annually to result in an incremental cost-effectiveness ratio of about NOK385 000 (US$43 780) per quality-adjusted life-year for MSU compared with standard care. The incremental cost-effectiveness ratio varies between some NOK1 000 000 (US$113 700) per quality-adjusted life-year if an MSU treats 100 patients per year and to about NOK340 000 (US$38 660) per quality-adjusted life-year if 300 patients with acute ischemic stroke are treated.Conclusions:MSU care in Norwegian settings is potentially cost-effective compared with conventional care, but this depends on a relatively high annual number of treated patients with acute ischemic stroke per vehicle. These results provide important information for MSU implementation in government-funded health care systems.

Immediate Recanalization of Large‐Vessel Occlusions by Tissue Plasminogen Activator Occurs in 28% of Patients Treated in a Mobile Stroke Unit

Background Recanalization of cerebral large‐vessel occlusions (LVOs) by intravenous thrombolysis is infrequent but has been relatively unexplored with ultraearly treatment. We evaluated prehospital treatment with tissue plasminogen activator (tPA) in a mobile stroke unit to explore the recanalization rate in patients with LVOs and its effect on early clinical improvement and long‐term disability. Methods Prospectively collected data were analyzed from Houston mobile stroke unit patients who were treated with tPA and had LVOs identified by either hyperdense arteries on computed tomography or arterial occlusion on computed tomography angiography while on board the mobile stroke unit. The primary outcome was immediate recanalization (IRC), categorized as resolution of LVO on repeat vascular imaging in the emergency department (ED) or on emergent angiography. The secondary outcome was change in National Institutes of Health Stroke Scale from baseline and modified Rankin score at 90 days. Results Sixty‐nine patients with anterior or posterior circulation LVOs were enrolled; the median time from last known normal to tPA bolus was 64.0 minutes (interquartile range, 52.0–89.0). Nineteen patients (28%) had IRC, with 11 based on computed tomography angiography on ED arrival and 8 based on first run of emergent angiography. Median time from tPA bolus to documentation of IRC was 61.0 minutes (interquartile range, 42.0–111.0). IRC was associated with improvement in median National Institutes of Health Stroke Scale from baseline (17.0 [14.0–22.0]) to ED arrival (10.0 [5.5–16.5]) and to 24 hours (4.0 [0.5–10.5]). Of the non‐IRC patients, 41 had recanalization after endovascular thrombectomy and 9 did not receive recanalization. The IRC group, earlier last known normal to tPA bolus, greater baseline National Institutes of Health Stroke Scale, and M1 and M2 middle cerebral artery occlusion locations were independently associated with greater improvement in National Institutes of Health Stroke Scale from baseline to ED arrival. The 90‐day modified Rankin score distribution was best in the IRC group, followed by the delayed recanalization group, and both had significantly less disability than the no recanalization group ( P =0.002). Conclusions Recanalization by ED arrival occured in 28% of patients with LVO who received tPA treatment in a mobile stroke unit and results in early clinical improvement and less disability at 90 days.

Premorbid frailty predicts short- and long-term outcomes of reperfusion treatment in acute stroke

Frailty is the most important short- and long-term predictor of disability in the elderly and, thus, might influence the clinical outcome of acute treatment of stroke. To evaluate whether frailty predicts short- and long-term all-cause mortality and neurological recovery in elderly patients who underwent reperfusion acute treatment of stroke. The study included consecutive patients older than 65years who underwent reperfusion treatment in a single stroke unit from 2015 to 2016. Predictors of stroke outcomes were assessed including demographics, baseline NIHSS, time to needle, treatment and medical complications. Premorbid frailty was assessed with a comprehensive geriatric assessment including functional, nutritional, cognitive, social and comorbidities status. At three and twelve months, all-cause death and clinical recovery (using modified Rankin scale, mRS) were evaluated. One-hundred and two patients who underwent acute reperfusion treatment for stroke entered the study (mean age 77.5, 65-94years). Frailty was diagnosed in 32 out of 102 patients and associated with older age (p = 0.001) but no differences in baseline NIHSS score, vascular risk profile or treatment management strategy. Frailty status was associated with worse improvement at 24h and higher in-hospital mortality. At follow-up, frail patients showed poorer survival at 3 (25% vs 3%, p = 0.008) and 12 (38% vs 7%, p = 0.001) months. Frailty was the best predictor of neurological recovery at one year follow-up (mRS 3.2 ± 1.9 vs 1.9 ± 1.9). Frailty is an important predictor of efficacy of acute treatment of stroke beyond classical predictors of stroke outcomes. Larger longitudinal studies are, thus, warranted to evaluate the risk-benefit of reperfusion treatment in the growing elderly frail population.

Access to stroke care in Europe: results of a vignette approach

Abstract Background Stroke is a major cause of death and disability in Europe. European guidelines for patients with ischemic stroke (about 85% of all strokes) recommend rapid access to hospital care and rehabilitation after discharge from hospital. Information on access to stroke care in Europe is limited. Methods A stroke vignette was developed reflecting typical patient characteristics and a recommended patient pathway: ambulance transfer to hospital, fast-track diagnostic work-up, thrombolysis and mechanical thrombectomy, stroke unit treatment, and inpatient rehabilitation. Experts in 12 countries were asked to complete a survey on service coverage, cost sharing, physical access (availability) and other barriers to access. Survey results were analysed and access to services was categorized into good, medium, bad before summarizing results across countries. Results Completed surveys were received from ten countries, including Bulgaria, Estonia, France, Germany, Lithuania, the Netherlands, Poland, Portugal, Slovakia, and the UK (England). Stroke patients in France, Germany, and the Netherlands have relatively good access, while substantial barriers exist in Bulgaria, Estonia, Poland, and Slovakia. In Bulgaria, rehabilitation is not covered by the National Health Fund; and rehabilitation capacity is very limited in Estonia, Poland, and Slovakia, leading to limited access. Almost all recommended services are formally covered by public financing schemes, but insufficient availability or organisational problems limit access to thrombolysis in Bulgaria, France, Lithuania, Poland, and Portugal or thrombectomy in Bulgaria and the UK (England). Conclusions While stroke related services are formally covered in almost all countries, considerable access problems exist in several countries. Future cross-country surveys of access to stroke care should collect quantitative data related to proportions of patients receiving particular services as well as qualitative data on access barriers.

Telemedicine for stroke

The term “telestroke” was first introduced by Levine ad Gorman in 1999. Since then many telestroke networks have been developed throughout the world more than 22 in Germany alone, performing more than 38.211 teleconsultations per year. Most telestroke networks are organized in a hub and spokes system: one or several comprehensive stroke centers (hub), advise several regional or community hospitals (spoke) in stroke care. The degree of treatment possibilities in the spokes hospitals is highly variable; while some telestroke networks offer only hyperacute stroke treatment i.e. identifying strokes and performing thrombolysis onsite (TSRH-telemedicine-assisted Stroke Ready Hospitals), others have developed local stroke Units (TSU-Telemedical Stroke Units) and provide stroke care until the patient is discharged home/to a rehabilitation center. The backbone of every functioning telestroke network remains the implementation of standard operational procedures, regular staff trainings and quality management. Nowadays, telestroke is going far beyond thrombolysis and stroke unit treatment - the ultimate goal being to treat stroke patients from the beginning to the end remotely as close to the patients home as possible. Multiple telestroke projects target stroke from the onset to its rehabilitation and follow up care. To mention only a few, mobile stroke Units including CT scanners have brought thrombolysis to the patients front door, interventionalists are been flown by helicopter to regional hospitals to perform thrombectomy onsite, and patients are being discharged home with telerehabilitation programs. In conclusion, telestroke is a growing field, bringing qualitative and innovative stroke care closer to the patient.

COVID-19 Pandemic Impact on Care for Stroke in Australia: Emerging Evidence From the Australian Stroke Clinical Registry.

We present information on acute stroke care for the first wave of the COVID-19 pandemic in Australia using data from the Australian Stroke Clinical Registry (AuSCR). The first case of COVID-19 in Australia was recorded in late January 2020 and national restrictions to control the virus commenced in March. To account for seasonal effects of stroke admissions, patient-level data from the registry from January to June 2020 were compared to the same period in 2019 (historical-control) from 61 public hospitals. We compared periods using descriptive statistics and performed interrupted time series analyses. Perceptions of stroke clinicians were obtained from 53/72 (74%) hospitals participating in the AuSCR (80% nurses) via a voluntary, electronic feedback survey. Survey data were summarized to provide contextual information for the registry-based analysis. Data from the registry covered locations that had 91% of Australian COVID-19 cases to the end of June 2020. For the historical-control period, 9,308 episodes of care were compared with the pandemic period (8,992 episodes). Patient characteristics were similar for each cohort (median age: 75 years; 56% male; ischemic stroke 69%). Treatment in stroke units decreased progressively during the pandemic period (control: 76% pandemic: 70%, p < 0.001). Clinical staff reported fewer resources available for stroke including 10% reporting reduced stroke unit beds. Several time-based metrics were unchanged whereas door-to-needle times were longer during the peak pandemic period (March-April, 2020; 82 min, control: 74 min, p = 0.012). Our data emphasize the need to maintain appropriate acute stroke care during times of national emergency such as pandemic management.

Differences in acute ischaemic stroke care in Poland: analysis of claims database of National Health Fund in 2017.

Selected and basic indicators of acute ischaemic stroke care in Poland are reported cross-regionally based on the analysis of claims data of the National Health Fund (NFZ) in 2017, the most reliable source of healthcare funding in the country, being a single public payer. For research purposes, a selection algorithm based on the diagnosis coded as I63 according to the International Classification of Diseases (ICD-10) was used to identify all ischaemic stroke patients in the claims database provided by the NFZ. Stroke units and other centres providing treatment for acute ischaemic stroke patients were examined. The analysis showed marked differences between provinces in terms of stroke unit treatment availability. The crude and standardised rates of acute ischaemic stroke admissions to stroke units varied between provinces. Moreover, substantial differences were observed for the thrombolysis implementation rate, access to rehabilitation, hospital stay and early prognosis. As the leading cause of disability and the second leading cause of death in developed countries, stroke requires a well-organised, evidence-based healthcare system provided for both acute treatment and rehabilitation. Continuous monitoring of healthcare is crucial to identify weaknesses and areas for improvement.

Acute stroke treatment in old age

In patients over 80 years old, 4 of the 5 evidence-based acute treatments of ischemic stroke, i.e. stroke unit treatment, antiplatelet therapy, intravenous thrombolysis (IVT) and mechanical thrombectomy (MT) are effective but with a higher morbidity than in younger patients. The indications for the more invasive forms of treatment, such as IVT and MT are given in principle but have to be oriented to the individual patient comorbidities. In the case of failure of these procedures aconsistent therapeutic target change to palliative measures is appropriate. Decompressive craniotomy in space-occupying media infarction can be indicated up to the relative age limit of 60 years and absolute age limit of 70 years. Patients over 80years often do not undergo IVT or MT. Although the German approval for alteplase within the framework of IVT over the age of 80years suggests acareful and critical review of the indications, its use is generally recommended.

Inpatient TIA and stroke care in adult patients in Germany - retrospective analysis of nationwide administrative data sets of 2011 to 2017

BackgroundComprehensive administrative data on TIA and stroke cases and treatment modalities are fundamental for improving structural conditions and adjusting future strategies of stroke care.MethodsThe nationwide administrative database (German federal statistical office) was used to extract all adult inpatient TIA and stroke cases and corresponding procedural codes for the period 2011–2017. Numbers were specified according to age, sex, stroke unit (SU) and critical care treatment (ICU), early transfer, and in-hospital mortality.FindingsInpatient adult TIA/stroke cases increased from annually 102,406 / 250,199 (2011) to 106,245 / 264,208 (2017). 84% of strokes were ischemic (AIS) also having the highest relative increase most likely due to more accurate coding within the time period, 68.2% of AIS were treated on SUs. 78% of hemorrhagic strokes were intracerebral hematomas (ICH; rather than subarachnoid hemorrhages [SAH]). Hemorrhagic strokes were increasingly treated on SUs (32.6% [2011], 37.8% [2017]). 68.8% of SAH were treated on ICUs (ICH:36.3%, AIS:10.3%). Early transfer in AIS increased (2.0 to 3.1%). Hemorrhagic strokes were associated with higher in-hospital mortality (SAH:19.6%, ICH:28.2%, AIS:7.3%).InterpretationThe absolute increase of strokes presumably reflects the aging society and more awareness for cerebrovascular disease. The relative increase of AIS may be attributable to an increased neurological expertise. The increasing amount of early transfers in AIS reflects new specialized treatment options. Our findings reflect the need for structural adjustments in inpatient stroke care.

Schlaganfallakuttherapie im Alter

In patients over 80 years old, 4 of the 5 evidence-based acute treatments of ischemic stroke, i.e. stroke unit treatment, antiplatelet therapy, intravenous thrombolysis (IVT) and mechanical thrombectomy (MT) are effective but with a higher morbidity than in younger patients. The indications for the more invasive forms of treatment, such as IVT and MT are given in principle but have to be oriented to the individual patient comorbidities. In the case of failure of these procedures aconsistent therapeutic target change to palliative measures is appropriate. Decompressive craniotomy in space-occupying media infarction can be indicated up to the relative age limit of 60 years and absolute age limit of 70 years. Patients over 80years often do not undergo IVT or MT. Although the German approval for alteplase within the framework of IVT over the age of 80years suggests acareful and critical review of the indications, its use is generally recommended.

Patient and service factors associated with referral and admission to inpatient rehabilitation after the acute phase of stroke in Australia and Norway

BackgroundUnequal access to inpatient rehabilitation after stroke has been reported. We sought to identify and compare patient and service factors associated with referral and admission to an inpatient rehabilitation facility (IRF) after acute hospital care for stroke in two countries with publicly-funded healthcare.MethodsWe compared two cohorts of stroke patients admitted consecutively to eight acute public hospitals in Australia in 2013–2014 (n = 553), and to one large university hospital in Norway in 2012–2013 (n = 723). Outcomes were: referral to an IRF; admission to an IRF if referred. Logistic regression models were used to identify and compare factors associated with each outcome.ResultsParticipants were similar in both cohorts: mean age 73 years, 40–44% female, 12–13% intracerebral haemorrhage, ~ 77% mild stroke (National Institutes of Health Stroke Scale < 8). Services received during the acute admission differed (Australia vs. Norway): stroke unit treatment 82% vs. 97%, physiotherapy 93% vs. 79%, occupational therapy 83% vs. 77%, speech therapy 78% vs. 13%. Proportions referred to an IRF were: 48% (Australia) and 37% (Norway); proportions admitted: 35% (Australia) and 28% (Norway). Factors associated with referral in both countries were: moderately severe stroke, receiving stroke unit treatment or allied health assessments during the acute admission, living in the community, and independent pre-stroke mobility. Directions of associations were mostly congruent; however younger patients were more likely to be referred and admitted in Norway only. Models for admission among patients referred identified few associated factors suggesting that additional factors were important for this stage of the process.ConclusionsSimilar factors were associated with referral to inpatient rehabilitation after acute stroke in both countries, despite differing service provision and access rates. Assuming it is not feasible to provide inpatient rehabilitation to all patients following stroke, the criteria for the selection of candidates need to be understood to address unwanted biases.

Integrated multidisciplinary assessment of cerebral stroke outcome after treatment in a comprehensive stroke unit

Objective – to explore the possibility of integral assessment of the stroke outcome and to develop a method of integral assessment of the stroke outcome after in-patient treatment on the level of impairment and and the level of activities of daily living, which were assessed using rating scales and indices.Materials and methods. The study was conducted at the Stroke Center (SC), Oberig’ multidisciplinary hospital division, which operates according to the principles of Comprehensive Stroke Unit. Patients with a cerebral stroke who were admitted to the SC in 2010–2018 were enrolled. The data of the participants were prospectively entered into a special database and included discharge assessments using 8 valid rating scales and indices. Cluster analysis methods (in particular Kohonen neural networks) were used to design the integral assessment. Statistical analysis of the values ​​of the rating scales and indices in the selected clusters was performed using the Kruskal–Wallis criterion, post hoc comparisons were made using the Dunn multiple comparison criterion.Results. 852 patients (42.5 % women and 57.5 % men, median age – 66.7 year) were enrolled. 81 % of patients were diagnosed with ischemic stroke, and 19 % had hemorrhagic stroke. According to the chosen method, it is necessary and sufficient to split the data into 4 clusters. All participants in the study according to their assessments at discharge using the set of selected measures could be assigned to one of 4 isolated clusters: K1 (n = 366), K2 (n = 93), K3 (n = 104) or K4 (n = 289). National Institutes of Health Stroke Scale, modified Rankin scale, Barthel Index, Berg Balance Scale та Functional Ambulation Classification were the most significant determinants of the patient cluster. For the 5 measures there have been significant differences (p &lt; 0.001) in the four clusters. The condition of the patients in K4 cluster was the best (p &lt; 0.05), whereas the patients in the K1 cluster were worse (p &lt; 0.05), and the condition of the patients in the clusters K2 and K3 was much worse (p &lt; 0.05) compared with the cluster K4.Conclusions. Based on the integrated assessments of neurological impairments and activities of daily living all of stroke patients could be assigned to one of four identified clusters. Detecting predictors of poor outcome after in-patient management may help to find ways to improve their prognosis.

Age and Sex Differences in Ischemic Stroke Treatment in a Nationwide Analysis of 1.11 Million Hospitalized Cases.

Background and Purpose- To date, there is still uncertainty about age and sex differences in access to stroke unit treatment and use of intravenous thrombolysis (IVT), while age and sex differences have not been investigated for the new treatment option of mechanical thrombectomy (MT). We, therefore, undertook a complete nationwide analysis of all hospitalized ischemic stroke patients in Germany from 2013 to 2017. Methods- We used the nationwide administrative database of the German Federal Statistical Office and investigated access to stroke unit treatment, IVT, MT, and in-hospital mortality. Patients were subdivided into 6 predefined age groups (20-44, 45-59, 60-69, 70-79, 80-89, and >90 years). Pooled overall and age group estimates were calculated using the random-effects model. To evaluate potential sex disparities, we estimated odds ratios (ORs) with 95% CIs. Results- A total of 1 112 570 patients were hospitalized for first or recurrent ischemic stroke from 2013 to 2017. Overall, stroke unit treatment increased significantly from 66.8% in 2013 to 73.5% in 2017, as did IVT (from 12.4% to 15.9%) and MT (from 2.4% to 5.8%; all P<0.001). Although the difference became smaller over time, patients ≥80 years of age still received significantly less often treatments. Men of all age groups had a significantly higher probability receiving stroke unit treatment (OR, 1.11; 95% CI, 1.09-1.12) and lower in-hospital mortality (OR, 0.91; 95% CI, 0.89-0.93). No disparity was observed in the use of IVT (OR, 1.00; 95% CI, 0.98-1.01), while women of all ages were treated more often with MT (OR, 1.26; 95% CI, 1.22-1.30). Conclusions- Access to stroke unit treatment has to be increased in both older patients and women of all ages. While there was no sex difference in IVT use, it is important to further investigate the significantly higher frequency of MT in women with ischemic stroke irrespective of age.
