Dahl MH, Rønning OM, Thommessen B. Delirium in acute stroke , prevalence and risk factors. Acta Neurol Scand: 2010: 122 (Suppl. 190): 39,43. © 2010 John Wiley & Sons A/S. Background,,, Delirium is frequently seen as a major complication among elderly stroke patients. Few studies have prospectively studied delirium as a complication of acute stroke. In these studies, the results are conflicting regarding risk factors and estimated prevalence. The aims of the present study are to assess the prevalence of delirium in patients with acute stroke treated in an acute Stroke Unit, identify characteristics of patients with delirium and important factors associated with the development of delirium. Methods,,, We conducted a prospective study of patients with delirium and acute stroke consecutively admitted to a Stroke Unit. The diagnosis of delirium was based on Confusion Assessment Method (CAM). CAM is devised from DSM-III-R criteria based on the diagnosis of delirium, and is a simple test with high sensitivity and specificity. Results,,, One hundred and seventy-eight patients with a diagnosis of stroke were eligible for the study. The prevalence of delirium in acute stroke in our study was 10% (18 of 178 patients). Patients with delirium had significantly longer length of stay in the Stroke Unit (12.3 vs 8.5 days, P < 0.004). Prestroke dementia [odds ratio (OR) 18.7], hemianopsia (OR 12.3), apraxia (OR 11.0), higher age (OR 5.5) and infection (UTI or pneumonia) (OR 4.9) during in-hospital stay were associated with increased risk of delirium. Conclusion,,, One of 10 stroke patients had delirium. This is the lowest prevalence of delirium shown in acute stroke patients. In our study, all patients were treated in a Stroke Unit. A Stroke Unit like the Scandinavian model may be beneficial in preventing delirium. [source]

The ep,dem,ology of post-stroke ep,lepsy accord,ng to stroke subtypes

ACTA NEUROLOGICA SCANDINAVICA, Issue 1 2006
G. Benbir
Objectives,,, Strokes represent the most common etiology of epilepsy in patients over the age of 60 years, with an incidence of 2,4% occurring in different studies. Materials and Methods,,, In this observational study, 1,428 patients were included who had stroke and were admitted to our Stroke Unit between the years 1996 and 2005. Results,,, Overall, 51 patients had post-stroke epilepsy (3.6%). Post-ischemic epilepsy occurred in 70.6% of the patients, post-hemorrhagic epilepsy occurred in 21.6% of the patients and epilepsy following venous infarctions occurred in 7.8% of all post-stroke epilepsy patients. Of 1,327 patients having ischemic stroke, 36 patients (2.7%), 11 out of 86 patients with hemorrhagic stroke (12.8%) and 4 of 15 patients with venous infarctions (26.6%) developed epilepsy. Compared with stroke patients without epilepsy, hemorrhagic (P < 0.001) and venous infarctions were more common in patients with post-stroke epilepsy (P < 0.001). The right hemisphere and the middle cerebral artery (MCA) territory were most commonly observed in ischemic and hemorrhagic stroke patients. Conclusions,,, Our results indicate that post-stroke epilepsy is more common among patients who have experienced venous infarctions. Hemorrhagic and venous infarctions are more commonly encountered in post-stroke epilepsy patients. Atherosclerotic and cardioembolic strokes were similar to those that occurred in post-stroke epilepsy patients. Localizations in post-stroke epileptic patients showed that the majority occurred in the right hemisphere, in the territory of the MCA. However, prospective, multicentered studies are needed for a better understanding of the epidemiology and social impact of post-stroke epilepsy. [source]

Stroke units: many questions, some answers

INTERNATIONAL JOURNAL OF STROKE, Issue 1 2009
Blanca Fuentes
Background The development of specialized stroke units has been a landmark innovation in acute stroke care. However, the high scientific evidence level for the recommendation for stroke units to provide clinical attention for acute stroke patients does not correspond to the level of stroke unit implementation. A narrative, nonsystematic review on published studies on stroke units was conducted, with special emphasis on those demonstrating their efficacy and effectiveness. We also attempt to provide some answers to several open questions regarding practical issues of stroke units. Summary of review Stroke units represent the most efficacious model for care provision compared with general ward care and stroke teams. Every stroke patient can benefit from stroke unit care. These units are efficient, cost-effective and their benefits are consistent over time. Compared with other specific stroke therapies such as aspirin or intravenous thrombolytic agents, stroke units have a higher target population and higher benefit in terms of number of deaths and/or dependencies avoided. New approaches in stroke unit management such as the implementation of noninvasive monitoring or alternative clinical pathways could improve their benefit even further. Conclusion Stroke units are cost-effective and need to be considered as a priority in health-care provision for stroke patients. [source]

Changes in Mini Mental State Examination score after stroke: lacunar infarction predicts cognitive decline

EUROPEAN JOURNAL OF NEUROLOGY, Issue 5 2006
P. Appelros
Stroke and cognitive impairment are inter-related. The purpose of this study was to show the natural evolution of cognitive performance during the first year after a stroke, and to show which factors that predict cognitive decline. Subjects were patients with a first-ever stroke who were treated in a stroke unit. A total of 160 patients were included. At baseline patients were evaluated with regard to stroke type, stroke severity, pre-stroke dementia and other risk factors. Mini Mental State Examinations (MMSE) were performed after 1 week and after 1 year. Patients had a median increase of 1 point (range ,8 to +9) on the MMSE. Thirty-two pre cent of the patients deteriorated, 13% were unchanged, and 55% improved. Lacunar infarction (LI) and left-sided stroke were associated with a failure to exhibit improvement. Patients with LI had an average decline of 1.7 points, whilst patients with other stroke types had an average increase of 1.8 points. Most stroke survivors improve cognitively during the first year after the event. The outcome for LI patients is worse, which suggests that LI may serve as a marker for concomitant processes that cause cognitive decline. [source]

Statin administration prior to ischaemic stroke onset and survival: exploratory evidence from matched treatment,control study

EUROPEAN JOURNAL OF NEUROLOGY, Issue 7 2005
S. Aslanyan
In addition to their lipid-lowering effects, it has been speculated that statins may also have beneficial effects on cerebral circulation and brain parenchyma during ischaemic stroke and reperfusion. We hypothesized that patients who had taken statins prior to stroke onset may have a better survival rate at 1 month and during the follow-up period. We retrospectively studied consecutive ischaemic stroke patients admitted to an acute stroke unit and at least a month's follow-up. From these, we included those patients who, at admission, had reported the use of a statin prior to the stroke onset in the statin group (n = 205). Each patient in the statin group was matched with two patients who reported no statin use (n = 410). Using logistic regression and Cox proportional hazards models, we adjusted for variables that significantly differed between treatment groups or that independently predicted mortality. After adjusting for those variables, statin use was associated with reduced mortality at 1 month [odds ratio 0.24; 95% confidence interval (CI) 0.09,0.67] and during the follow-up period (hazard ratio 0.57; 95% CI 0.35,0.93). The use of statins prior to stroke onset is associated with improved stroke survival within this cohort study with matched controls. [source]

Clinical features associated with medically unexplained stroke-like symptoms presenting to an acute stroke unit

EUROPEAN JOURNAL OF NEUROLOGY, Issue 2 2005
F. S. Nazir
In many areas of secondary care, symptoms unexplained by disease account for around one-third of all patients seen. We sought to investigate patients presenting with medically unexplained stroke-like symptoms to identify distinguishing features which may help to identify a non-organic aetiology. Patients given a discharge diagnosis of medically unexplained stroke-like symptoms over the preceding 11 years were identified retrospectively from a prospectively completed stroke unit database. Age- and sex-matched controls with ischaemic or haemorrhagic stroke or transient ischaemic attack were also identified. Clinical features on presentation, ischaemic risk factors, alcohol history, marital status and history of depression or anxiety were examined. Previous or subsequent admissions with medically unexplained syndromes were also examined via record linkage with hospital discharge records. A medically unexplained syndrome was assumed to be present if an International Classification of Diseases 9 discharge code for one or more of the thirteen conditions forming recognized functional syndromes was given. Logistic regression was applied to determine predictors of non-organicity. One hundred and five patients and controls, 1.6% of all stroke unit admissions were identified, 62% (65 patients) were females. Mean age was 50.3 ± 14.9. Compared with age- and sex-matched controls patients with medically unexplained stroke-like symptoms were significantly more probable to have a headache at presentation (47% vs. 26%, P = 0.0004), have a diagnosis of one or more additional medically unexplained syndromes (24% vs. 11%, P = 0.007) but significantly less probable to present with symptoms of vertebrobasilar dysfunction (32% vs. 61%, P < 0.0001). A history of anxiety or depression, as recorded in the notes, was not found to be associated with a medically unexplained presentation. Medically unexplained stroke-like presentations are common (1.6% of all stroke presentations), they are most strongly predicted by the presence of other functional somatic syndromes, headache and the absence of symptoms of vertebrobasilar dysfunction.

Establishment of a stroke unit in a district hospital: review of experience

INTERNAL MEDICINE JOURNAL, Issue 2 2007
A. Chiu
Abstract Background: The experience and outcomes of co-locating acute stroke and stroke rehabilitation care in a district hospital were reviewed. Method: Information for patients admitted to Blacktown and Mt Druitt Hospitals before and after setting up an acute stroke unit (SU) (12 months data for each period), including mortality and length of stay (LOS) at the hospital were obtained from various sources, including the diagnosis-related group and subacute and non-acute casemix databases. Results: There was a significant reduction of mortality (18 vs 10%; P = 0.01) and reduced total LOS (46 vs 39 days; P = 0.01) with similar functional outcomes in the post-SU period. Fifty per cent of patients were unable to access the acute SU. Patients admitted into the SU had lower mortality (5 vs 14%; P = 0.01) and were also discharged from hospital earlier (35 vs 54 days; P = 0.01) than patients admitted into general wards during the post-SU period. Thirty-four per cent of patients received rehabilitation within the rehabilitation facility in the post-SU period compared with 19% in the pre-SU period. Conclusion: The Blacktown experience showed the feasibility of establishing a co-located SU within rehabilitation facility with good outcomes as illustrated by the significant reduction in the stroke mortality, a reduction in the total LOS and an increase in the number of patients receiving rehabilitation post-stroke.

Understanding nursing on an acute stroke unit: perceptions of space, time and interprofessional practice

JOURNAL OF ADVANCED NURSING, Issue 9 2009

Abstract Title.,Understanding nursing on an acute stroke unit: perceptions of space, time and interprofessional practice. Aim. This paper is a report of a study conducted to uncover nurses' perceptions of the contexts of caring for acute stroke survivors. Background. Nurses coordinate and organize care and continue the rehabilitative role of physiotherapists, occupational therapists and social workers during evenings and at weekends. Healthcare professionals view the nursing role as essential, but are uncertain about its nature. Method. Ethnographic fieldwork was carried out in 2006 on a stroke unit in Canada. Interviews with nine healthcare professionals, including nurses, complemented observations of 20 healthcare professionals during patient care, team meetings and daily interactions. Analysis methods included ethnographic coding of field notes and interview transcripts. Findings. Three local domains frame how nurses understand challenges in organizing stroke care: 1) space, 2) time and 3) interprofessional practice. Structural factors force nurses to work in exceptionally close quarters. Time constraints compel them to find novel ways of providing care. Moreover, sharing of information with other members of the team enhances relationships and improves ,interprofessional collaboration'. The nurses believed that an interprofessional atmosphere is fundamental for collaborative stroke practice, despite working in a multiprofessional environment. Conclusion. Understanding how care providers conceive of and respond to space, time and interprofessionalism has the potential to improve acute stroke care. Future research focusing on nurses and other professionals as members of interprofessional teams could help inform stroke care to enhance poststroke outcomes. [source]

Neuroimaging Determinants of Cognitive Performances in Stroke Associated With Small Vessel Disease

JOURNAL OF NEUROIMAGING, Issue 2 2005
V. Mok MD
ABSTRACT Background and Purpose. Controversies still exist as to the neuroimaging determinants of cognitive impairment in cerebral small vessel disease (SVD). The authors studied the neuroimaging correlates of cognitive performances among patients with stroke associated with SVD. Methods. The authors per formed cerebral computed tomography, magnetic resonance imaging, and diffusion-weighted imaging among 74 consecu tive patients admitted to the acute stroke unit because of stroke associated with SVD. They examined the association between cognitive performances and the following neuroimaging features: volume of white matter changes (WMC), multiplicity of lacunae, location of lacunae, total cerebral atrophy, and frontal and medial temporal lobe atrophy. Results. Apart from age and education, univariate linear regression analyses revealed that WMC volume, presence of thalamic lacunae, cerebral atrophy, and left frontal lobe atrophy predicted performance on the Mini-Mental State Examination while WMC volume, presence of thalamic infarcts, cerebral atrophy, and frontal lobe atrophy of both sides predicted performance on the Mattis Dementia Rat ing Scale-Initiation/Preservation subscale. In the multivariate analyses, education (R2= 0.22, P < .001), left frontal lobe atrophy (R2= 0.10, P= .004), and presence of thalamic lacunae (R2= 0.04, P= .049) were found to predict performance on the Mini-Mental State Examination while age (R2= 0.23, P < .001) and presence of thalamic lacunae (R2= 0.08, P= .011) were found to predict performance on the Mattis Dementia Rating Scale-Initiation/Preservation. Conclusions. Among patients with stroke associated with SVD, thalamic lacunae and frontal lobe atrophy are key determinants of cognitive performances. [source]

Therapists' experiences and perceptions of teamwork in neurological rehabilitation: reasoning behind the team approach, structure and composition of the team and teamworking processes

PHYSIOTHERAPY RESEARCH INTERNATIONAL, Issue 2 2006
Kitty Maria Suddick
Abstract Background and Purpose.,Teamwork and the interdisciplinary team approach have been strongly advocated for use in the provision of neurological rehabilitation services. However, whether teamwork has been adopted, and in what form, has yet to be established. The present study investigated therapists' experiences and perceptions of the reasoning behind the team approach in neurological rehabilitation, the structure and composition of the team within which they worked and the teamworking process,Method.,This article reports part of an exploratory qualitative study. Five occupational therapists and five physiotherapists from three teams: a rehabilitation centre; a community team; and a stroke unit based within the UK. Semi-structured interviews were undertaken with each participant and then transcribed. Content and thematic analysis of the qualitative interview data was carried out, with respondents validating both the transcription and analysis stages.,Results.,Perceived composition and structure of the neurological rehabilitation team was variable across teams and between individual team members. There was disparity as to whether patients were included within the neurological team; the interdisciplinary team approach had not been consistently adopted and there were sub-teams and other team memberships in existence. Reasoning behind the team approach supported the perceived benefits of teamwork from a number of perspectives, and the activities reported as part of the team process were diverse.,Conclusions.,Different teams may choose to use different strategies depending on the aims and context of the team effort. In some instances interdisciplinary teamwork and patient-centred approaches were not adopted consistently and the process of teamwork itself is both complex and diverse.

Is dosage of physiotherapy a critical factor in deciding patterns of recovery from stroke: a pragmatic randomized controlled trial

PHYSIOTHERAPY RESEARCH INTERNATIONAL, Issue 4 2000
Dr Cecily Partridge
Abstract Background and Purpose The best treatment and management of stroke patients has been shown to be in stroke units by multidisciplinary rehabilitation teams. Since the composition of stroke units differs it is important to know the extent to which the different components contribute to this result. Physiotherapy is one component of most rehabilitation teams and recent systematic reviews have shown that patients with stroke receiving more physiotherapy achieve more recovery from disability. However, information about the actual amounts of physiotherapy needed to achieve this result is not known. Method A pragmatic, randomized, single-blind, controlled trial comparing recovery from disability in subjects receiving the current standard amount of 30 minutes' physiotherapy with those receiving double that amount (60 minutes). The study included measures of physical performance and function, psychological aspects of anxiety and depression, and perceived control over recovery. Results Some 114 subjects were recruited to the study; full six-week data are available for 104 subjects and six-month data for 93 subjects. Comparison of initial to six-week difference scores in the control and intervention groups of the whole sample did not show a significant difference. Scrutiny of the recovery curves of the whole sample showed that, in half the sample, three distinct patterns of recovery were demonstrated. Conclusion These results suggest that doubling the physiotherapy time available for patients in a stroke unit will not provide a measurable benefit for all patients. The subgroup analysis of patterns of recovery must be regarded as speculative, but provides the basis for hypotheses about those likely to respond well to more intensive therapy.

The hospital costs of care for stroke in nine European countries

HEALTH ECONOMICS, Issue S1 2008
David Epstein
Abstract Stroke is a major cause of mortality and morbidity, but the reasons for differences in costs of care within and between countries are not well understood. The HealthBASKET project used a vignette methodology to compare the mean costs and prices of hospital care across providers in nine European Union countries. Data on resource use, unit costs and prices of care for female stroke patients without co-morbidity were collected from a sample of 50 hospitals. Mean costs for each provider were analysed using multiple regression. Sensitivity analysis explored the effects on cost of using official exchange rates, purchasing power parity (PPP) and proportion of national income per capita. The mean cost of a hospital episode per patient for stroke at PPP was ,3813 (standard error 227) with an additional day in hospital typically associated with 6.9% (95% CI: 4,9%) higher costs and thrombolysis associated with 41% higher costs (10,73%). After adjusting for explanatory factors, about 76% of the variation in cost could be attributed to between-country differences, and the extent of this variation was sensitive to the method of currency conversion. There was considerable variation in the care pathways within and between countries, including differences in the availability of stroke units and access to rehabilitative services, but only the length of stay and use of thrombolytic therapy were significantly associated with higher cost. The vignette methodology appears feasible, but further research needs to consider access to healthcare over a longer follow up and to include both costs and outcomes.

Stroke units: many questions, some answers

Improving clinical practice in stroke through audit: results of three rounds of National Stroke Audit

JOURNAL OF EVALUATION IN CLINICAL PRACTICE, Issue 4 2005
P. Irwin BA RGN MSc
Abstract Background, The results of three rounds of National Stroke Audit in England,, Wales and Northern, Ireland are, compared. Methods, Audit of the organization of stroke services and retrospective case-note audit of up to 40 consecutive cases admitted per hospital over a 3-month period was conducted in each of 1998, 1999 and 2001/02. The changes in the organizational, case-mix and process results of the hospitals that had participated in all three rounds were analysed. Results, 60% of all eligible trusts from England, Wales and Northern Ireland took part in all three audits in 1998, 1999 and 2001/02. Total numbers of cases were 4996, 4841 and 5152, respectively. Case-mix variables were similar over the three rounds. Mortality at 7 and 30 days fell by 3% and 5%, respectively. The proportion of hospitals with a stroke unit rose from 48% to 77%. The proportion of patients spending most of their stay in a stroke unit rose from 17% in 1998 to 26% in 1999 and 29% in 2001/02. Improvements achieved in process standards of care between 1998 and 1999 (median change was a gain of 9%) failed to improve further by 2001/02 (median change was 0%). In all three rounds process standards ,of ,care ,tended ,to ,be ,better ,in ,stroke units. Conclusions, Three rounds of national audit of stroke care have shown standards of care on stroke units were notably higher than on general wards. Slowing in the rise of the proportion managed on stroke units mirrors the slow down in improvement to overall national standards of care. To further improve outcomes and national standards of stroke care a much higher proportion of patients needs to be managed in stroke units. [source]
