Abstract
BACKGROUND Stroke readmissions are considered a marker of health quality and may pose a burden to healthcare systems. However, information on the costs of post-stroke readmissions has not been systematically reviewed. OBJECTIVES To systematically review information about the costs of hospital readmissions of patients whose primary diagnosis in the index admission was a stroke. METHODS A rapid systematic review was performed on studies reporting post-stroke readmission costs in EMBASE, MEDLINE, and Web of Science up to June 2021. Relevant data were extracted and presented by readmission and stroke type. The original study's currency values were converted to 2021 US dollars based on the purchasing power parity for gross domestic product. The reporting quality of each of the included studies was assessed using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist. RESULTS Forty-four studies were identified. Considerable variability in readmission costs was observed among countries, readmissions, stroke types, and durations of the follow-up period. The UK and the USA were the countries reporting the highest readmission costs. In the first year of follow-up, stroke readmission costs accounted for 2.1-23.4%, of direct costs and 3.3-21% of total costs. Among the included studies, only one identified predictors of readmission costs. CONCLUSION Our review showed great variability in readmission costs, mainly due to differences in study design, countries and health services, follow-up duration, and reported readmission data. The results of this study can be used to inform policymakers and healthcare providers about the burden of stroke readmissions. Future studies should not solely focus on improving data standardization but should also prioritize the identification of stroke readmission cost predictors.

Social and economic costs and health-related quality of life in stroke survivors in the Canary Islands, Spain. BMC Health Serv Res 2012; 12:315. [PMID: 22970797 PMCID: PMC3468368 DOI: 10.1186/1472-6963-12-315] [Citation(s) in RCA: 59] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2011] [Accepted: 08/31/2012] [Indexed: 01/31/2023] Open
Abstract
BACKGROUND Cost-of-illness analysis is the main method of providing an overall vision of the economic impact of a disease. Such studies have been used to set priorities for healthcare policies and inform resource allocation. The aim of this study was to determine the economic burden and health-related quality of life (HRQOL) in the first, second and third years after surviving a stroke in the Canary Islands, Spain. METHODS Cross-sectional, retrospective study of 448 patients with stroke based on ICD 9 discharge codes, who received outpatient care at five hospitals. The study was approved by the Research Ethics Committee of Nuestra Señora de la Candelaria University Hospital. Data on demographic characteristics, health resource utilization, informal care, labor productivity losses and HRQOL were collected from the hospital admissions databases and questionnaires completed by stroke patients or their caregivers. Labor productivity losses were calculated from physical units and converted into monetary units with a human capital-based method. HRQOL was measured with the EuroQol EQ-5D questionnaire. Healthcare costs, productivity losses and informal care costs were analyzed with log-normal, probit and ordered probit multivariate models. RESULTS The average cost for each stroke survivor was €17 618 in the first, €14 453 in the second and €12 924 in the third year after the stroke; the reference year for unit prices was 2004. The largest expenditures in the first year were informal care and hospitalizations; in the second and third years the main costs were for informal care, productivity losses and medication. Mean EQ-5D index scores for stroke survivors were 0.50 for the first, 0.47 for the second and 0.46 for the third year, and mean EQ-5D visual analog scale scores were 56, 52 and 55, respectively. CONCLUSIONS The main strengths of this study lie in our bottom-up-approach to costing, and in the evaluation of stroke survivors from a broad perspective (societal costs) in the first, second and third years after surviving the stroke. This type of analysis is rare in the Spanish context. We conclude that stroke incurs considerable societal costs among survivors to three years and there is substantial deterioration in HRQOL.

Abstract
Background and Purpose—
Treatment of stroke consumes a significant portion of all healthcare expenditure. We developed a system for monitoring costs from individual patient data on a national level in Finland.
Methods—
Multiple national administrative registers were linked to gain episode-of-care data on all hospital-treated patients with incident stroke over the years 1999 to 2007 (n=94 316). Inpatient and specialist outpatient costs were evaluated with a cost database, long-term care costs with fixed prices, and medication costs with true retail prices.
Results—
For the patients of Year 2007, the mean 1-year costs after an ischemic stroke were $29 580, after an intracerebral hemorrhage $36 220, and after a subarachnoid hemorrhage $42 570, valued in Year 2008 US dollars. Only part of these costs are attributable to stroke, because the annual costs prior to stroke were significant, $8900 before ischemic stroke, $7600 before intracerebral hemorrhage, and $4200 before subarachnoid hemorrhage. Older patients with ischemic stroke, and, among patients with ischemic stroke and subarachnoid hemorrhage, women, incurred higher costs. The mean estimated lifetime costs were $130 000 after ischemic stroke or intracerebral hemorrhage and $80 000 after subarachnoid hemorrhage. Annually $1.6 billion is spent in the care of Finnish patients with stroke, which equals to 7% of the national healthcare expenditure, or 0.6% of the gross domestic product. Costs of patients with stroke are increasing with prolonged survival and the aging population.
Conclusions—
Treatment of patients with stroke is a large national investment. Setting up a nationwide system for continuous monitoring of stroke costs is feasible. Cost data should optimally be evaluated in conjunction with effectiveness and performance indicators.

Abstract
OBJECTIVES To estimate the annual socioeconomic costs of stroke in Korea in 2005 from a societal perspective. METHODS We identified those 20 years or older who had at least one national health insurance (NHI) claims record with a primary or a secondary diagnosis of stroke (ICD-10 codes: I60-I69, G45) in 2005. Direct medical costs of the stroke were measured from the NHI claims records. Direct non-medical costs were estimated as transportation costs incurred when visiting the hospitals. Indirect costs were defined as patients' and caregivers' productivity loss associated with office visits or hospitalization. Also, the costs of productivity loss due to premature death from stroke were calculated. RESULTS A total of 882,143 stroke patients were identified with prevalence for treatment of stroke at 2.44%. The total cost for the treatment of stroke in the nation was estimated to be 3,737 billion Korean won (KRW) which included direct costs at 1,130 billion KRW and indirect costs at 2,606 billion KRW. The per-capita cost of stroke was 3 million KRW for men and 2 million KRW for women. The total national spending for hemorrhagic and ischemic stroke was 1,323 billion KRW and 1,553 billion KRW, respectively, which together consisted of 77.0% of the total cost for stroke. Costs per patient for hemorrhagic and ischemic stroke were estimated at 6 million KRW and 2 million KRW, respectively. CONCLUSIONS Stroke is a leading public health problem in Korea in terms of the economic burden. The indirect costs were identified as the largest component of the overall cost.

Abstract
BACKGROUND AND PURPOSE With decision-analytic models becoming more popular to assess the cost-effectiveness of health care interventions, the need for robust estimates on the costs of cerebrovascular disease is paramount. This study reports the results from a literature review of the costs of cerebrovascular diseases, and assesses the quality of the published evidence against a set of defined criteria. METHODS A broad literature search was conducted. Those studies reporting mean/median costs of cerebrovascular diseases derived from patient-level data in a developed country setting were included. Data were abstracted using standardized reporting forms and assessed against 4 predefined criteria: use of adequate methodologies, use of a population-based study, inclusion of premorbid resource use, and reporting of costs by different patient subgroups. RESULTS A total of 120 cost studies were identified. The cost estimates of stroke were compared by taking into account the effects of inflation and price differentials between countries. Average costs of stroke ranged from $468 to $146 149. Differences in costs were also found within country, with estimates in the USA varying 20-fold. Although the costing methodologies used were generally appropriate, only 5 studies were based on population-based studies, which are the gold standard study design when comparing incidence, outcome, and costs. CONCLUSIONS This review showed large variations in the costs of stroke, mainly attributable to differences in the populations studied, methods, and cost categories included. The wide range of cost estimates could lead to selection bias in secondary health economic analyses, with authors including those costs that are more likely to produce the desired results.

Abstract
OBJECTIVES The geographic inequity and the wide variation in the patterns of care of stroke found across Europe together with the lack of health economics evaluation in Greece led to this prospective study, aiming to provide data on in-hospital direct cost of patients with an acute stroke in Greece, and to identify independent prognostic factors. METHODS Demographic and clinical data were recorded on 429 consecutive patients with an acute ischemic or hemorrhagic stroke admitted to a tertiary care hospital in Greece during a period of 18 months. The costs incurred were estimated using the official financial charts listing in euro (euro), the real expenditure of all hospital departments. RESULTS The direct in-hospital cost for all stroke cases was 1,551,445euro for a total of 4674 days (331.9euro per day in-hospital). The mean in-hospital cost per stroke patient was 3624.9euro (+/-2695.4). Hemorrhagic strokes were significantly more expensive than the ischemic strokes [mean 5305.4 (+/-4204.8)euro and 3214.5 (+/-1976.2)euro, respectively) and lacunar strokes the least expensive among ischemic stroke subtypes. The length of stay was highly correlated with in-hospital total cost. Multivariate linear regression analysis showed that admission ward, stroke severity on admission, stroke type and status discharge were independent predictors of cost. CONCLUSIONS Purchasers in our health services should differentiate in their cost estimates and pricing schemes between types of cerebrovascular events. Future studies should focus on modifiable factors related, not only with stroke characteristics, but also with operational policies of hospitals, that may influence length of stay.

Abstract
BACKGROUND In recent years a number of costs of stroke studies have been conducted based on incidence or prevalence and estimating costs at a given time. As there still is a need for a deeper understanding of factors influencing these costs the aim of this study was to calculate the direct and indirect costs in a younger (<65) sample of stroke patients and to explore factors affecting the costs. METHODS Fifty-eight patients included in a study of home rehabilitation and followed for 1 year after discharge from the rehabilitation unit, were interviewed about their use of health care services, assistance, medications and assistive devices. Costs (defined as the cost for society) were calculated. A linear regression of cost and variables of functioning, ability, community integration and health-related quality of life was done. RESULTS Inpatient care contributed substantially to the direct cost with a mean length of stay of 92 days. Rehabilitation during the first year constituted of an average of 28 days in day clinics, 38 physiotherapy sessions and 20 occupational therapy sessions. The total direct mean cost was 80 020 euro and the indirect cost 35 129 euro. The direct costs were influenced by the process skill (the ability to plan and perform a given task and to adapt when needed) and presence of aphasia. Indirect costs for informal care giving increased for patients with a lower health-related quality of life as well as a low score on home integration. CONCLUSION Costs are high in this group of young (< 65 years) stroke patients compared to other studies, partly due to the length of the stay and partly to loss of productivity.

Abstract
This study estimates the lifetime societal costs associated with incident intracerebral hemorrhage (ICH) in Spain. An epidemiological model of ICH incidence, survival and morbidity was developed using retrospective data from 28 hospitals in Andalusia and published data identified in a systematic literature review. Data on resource utilization and costs were obtained from five hospitals in the Canary Islands, whereas cost of outpatient care, informal care and lost productivity were obtained from standardized questionnaires completed by survivors of ICH. The lifetime societal costs of incident ICH in Spain is estimated at 46,193 euros per patient. Direct medical costs accounted for 32.7% of lifetime costs, whilst 67.3% were related to indirect costs. One-third of direct medical costs over the first year were attributable to follow-up care, including rehabilitation. Indirect costs were dominated by costs of informal care (71.2%). The aggregated lifetime societal costs for the estimated 12,534 Spanish patients with a first-ever ICH in 2004 was 579 million euros. ICH implies substantial costs to society primarily due to formal and informal follow-up care and support needed after hospital discharge. Interventions that offer survival benefits without improving patients' functional status are likely to further increase the societal costs of ICH.

Abstract
OBJECTIVES Stroke unit care has been shown to be beneficial but costly. In an own previous study, the resource utilization of stroke unit care has been evaluated. Since the resource utilization on regular neurological wards is widely unknown, we determined the costs for acute stroke care on regular neurological wards to compare both treatment settings. METHODS AND PATIENTS We included 253 consecutive in-patients with the diagnosis of ischemic stroke (IS), intracerebral hemorrhage (ICH) or transient ischemic attack (TIA) treated on regular wards at a German University Department of Neurology, between 1 January and 30 June 1998. The modified Rankin scale (mRS) was used to assess outcome. Costs of stroke care were calculated from the perspective of the healthcare provider (hospital) by using a bottom-up approach. Resource utilization was compared to stroke unit care as determined in a previous study. Prices of 2002 were used (in Euros). RESULTS IS was present in 78% (n=196), TIA in 13% (n=34), and ICH in 9% (n=23) of patients. Length of stay was 11.1+/-8.9 (mean+/-S.D., IS), 11.1+/-6.5 (TIA), and 16.9+/-15.5 (ICH) days (p>0.05). Mean costs of stroke care were euro 3060 (US$ 3180) for TIA, euro 3070 (US$ 3200) for IS and euro 5210 (US$ 5430) for ICH (p<0.05, ICH versus IS and TIA). The highest costs were due to non-medical care (46%) and personnel (25%). The mRS improved during hospitalization from 3.0+/-1.6 to 2.2+/-1.8 (p<0.01). Compared to care on regular neurological wards, mean costs per admission with treatment on stroke units increased by 7.0%, mean costs per day by 15.6%. CONCLUSION The comparison - considering a potential bias of patient selection - shows that acute stroke unit care is approximately 16% more costly than treatment on regular neurological wards due to higher resource use of personnel and diagnostic procedures. Stroke unit treatment tends to decrease post-acute in-patient care costs.

Abstract
BACKGROUND AND PURPOSE The economic impact of hemorrhagic stroke, including subarachnoid hemorrhage (SAH) and intracerebral hemorrhage (ICH), has not been well characterized compared to the more prevalent ischemic stroke (IS). METHODS Patients diagnosed with SAH, ICH or IS in 1997 were identified in a 5% national random sample of all Medicare beneficiaries. Medical care patterns and associated Medicare reimbursements were analyzed from one year prior to the index event through four years following that event. RESULTS 11,430 patients were identified with SAH (n = 342), ICH (n = 1,957) or IS (n = 9,131). Average Medicare expenditures, from the initial event through four years, were USD 48,327 for SAH, USD 38,023 for ICH and USD 39,396 for IS. CONCLUSIONS Long-term healthcare costs of SAH and ICH are substantial. With the expected increase in the elderly population over the coming decades, these results emphasize the need for effective preventive and acute medical care.

Abstract
Background and Purpose—
The number of stroke patients and the healthcare costs of strokes are expected to rise. The objective of this study was to determine the direct costs of first ischemic stroke and to estimate the expected increase in costs in Germany.
Methods—
An incidence-based, bottom-up, direct-cost-of-ischemic-stroke study from the third-party payer’s perspective was performed, incorporating 10-year survival data and 5-year resource use data from the Erlangen Stroke Registry. Discounted lifetime year 2004 costs per case were obtained and applied to the expected age and sex evolution of the German resident population in the period 2006 to 2025.
Results—
The overall cost per first-year survivor of first-ever ischemic stroke was estimated to be 18 517 euros (EUR). Rehabilitation accounted for 37% of this cost, whereas in subsequent years outpatient care was the major cost driver. Discounted lifetime cost per case was 43 129 EUR overall and was higher in men (45 549 EUR) than in women (41 304 EUR). National projections for the period 2006 to 2025 showed 1.5 million and 1.9 million new cases of ischemic stroke in men and women, respectively, at a present value of 51.5 and 57.1 billion EUR, respectively.
Conclusions—
The number of stroke patients and the healthcare costs of strokes in Germany will rise continuously until the year 2025. Therefore, stroke prevention and reduction of stroke-related disability should be made priorities in health planning policies.

Abstract
The purpose of this study was to determine the 12 months medical resource use following admission to hospital with acute stroke and to calculate costs from a societal perspective. Data of consecutive patients with confirmed stroke were analysed. Acute hospital data were taken from medical records, socio-demographic variables from patients' interviews. A follow-up questionnaire about resource utilization was completed by patients or proxies 12 months after acute hospital admission. Costs were calculated by multiplying medical resource units used with cost factors per unit. Mean age of a total of 383 patients was 65 years and 41% were female. The median length of the initial stay in the acute hospital was 12 days at an average cost of 4650 per patient (49% of direct costs). Rehabilitation (16%), readmission (11%), medication (9%), and nursing costs (6%) were other contributors to the direct costs which amounted to a total of 9452 +/- 7599 per patient during 12 months. Indirect cost amounted to a total of 2014 +/- 5312. Patients' age, severity and type of stroke influenced the total stroke-associated costs. The large economic burden of stroke indicates the need for assessing and improving efficient health care for affected patients.

Abstract
BACKGROUND AND PURPOSE The economic burden of stroke is substantial and is likely to increase with an increasing number of elderly individuals in the population. There is thus a need for information on the use of health care resources and costs among these elderly stroke patients. We examined the impact of the cognitive impairments on the ability to perform activities of daily living (ADL) and utilization and costs of health care in a cohort of elderly stroke patients. METHODS One hundred and forty-nine patients aged >/=70 years with acute stroke were included. The patients were assessed regarding their ability to carry out ADL and health resource utilization and cost during the first year after stroke. Cognitive impairments were assessed 18 months after the index stroke. RESULTS Stroke severity in acute stroke and cognitive impairment at 18 months after stroke onset was associated with impairment in ADL and increased costs for utilisation of care during the first year. Patients with cognitive impairment were more dependent on personal assistance in ADL. Costs per patient during the study were three times higher for patients with cognitive impairment. Hospital care, institutional living and different kinds of support from society accounted for the highest costs. CONCLUSIONS Costs of care utilisation during the first year after stroke were associated with cognitive impairments, stroke severity and dependence in ADL. The results should be interpreted cautiously as the assessment of cognitive function was made 18 months after stroke onset and costs were estimated for the first year after stroke.

Abstract
BACKGROUND AND PURPOSE Stroke outcomes in patients with atrial fibrillation (AF) tend to be worse than those in patients without AF. The objective of this study was to evaluate whether the cost benefits of anticoagulation for stroke prevention in AF may currently be underestimated by existing economic models that do not distinguish between different stroke outcomes. METHODS A literature review was conducted in 3 areas: (1) studies comparing stroke outcomes in AF and non-AF patients; (2) studies providing long-term cost of stroke estimates; and (3) studies modeling the cost-effectiveness of anticoagulation with a vitamin K antagonist (eg, warfarin) in AF patients. RESULTS There is considerable evidence that stroke in AF patients has a worse outcome than in patients without AF, including higher mortality, severity, and recurrence rates, and greater functional impairment and dependency. Estimates of the long-term cost of stroke of different severities were between US 24,991 dollars for a mild stroke over 5 years and US 142,251 dollars for a major ischemic stroke over a lifetime (2004 prices). The cost of a severe ischemic stroke may typically be 3-times that of mild stroke. However, cost-effectiveness models for anticoagulation in patients with AF have used average (not AF-specific) cost-of-stroke data, and most have used stroke severity distributions derived from clinical trials, which may differ from those in clinical practice. CONCLUSIONS Existing economic models underestimate the cost benefits of anticoagulation for stroke prevention because they do not adjust for poorer outcomes associated with cardioembolic strokes.

Abstract
OBJECTIVE The aim of this review is to summarize published data (based on a search of Medline sources, 1993-October 2003) from the last 10 years on the costs of stroke. With the recent encouraging evidence of interventions that reduce the incidence of stroke, the primary focus is on incidence-based cost of stroke studies to identify important factors for future cost-effectiveness analyses on stroke interventions. FINDINGS Lifetime costs per patient were in the range USD 11 787 for 'unclassified' stroke in Australia to USD 3035671 in stroke patients with untreated non-rheumatic atrial fibrillation in a UK setting (costs inflated to 2003 values). For the lifetime costs of ischemic stroke only, the range narrowed to USD 41257 in Australia and USD 104629 in the UK. These data confirm that stroke management is associated with a vast economic burden. No correlation of lifetime cost of stroke with specific cost components or time horizon was identified. The cost of stroke is influenced by severity (more severe strokes cost more due to extended hospitalization), age (costs were greater in younger stroke patients) and gender (direct costs were greater for women, but indirect costs were greater in men). CONCLUSION Conducting research according to methodological consensus would markedly improve the quality of data from future studies of stroke and support identification of the main cost drivers in different country-specific settings.

Abstract
Objectives:To estimate the excess cost of stroke in Sweden and the potential costs that could be avoided by preventing first-ever strokes.Methods:We adopted the incidence approach for estimating the present value of both direct and indirect costs. Data on mortality, stroke recurrence, and inpatient care were estimated from a national register of patient data with a four-year follow-up period. To estimate costs for social services, we used survey data on living conditions before stroke onset and at three and at twenty-four months. Costs for outpatient visits, rehabilitation, drugs, and production losses due to premature death and early retirement were estimated on the basis of both published and nonpublished sources. Lifetime costs were based on life tables adjusted for excess mortality of stroke, and costs in year 4 were extrapolated to subsequent years.Results:The present value direct cost for an average stroke patient is SEK513,800 (US$56,024 or Euro60,825). The corresponding indirect cost is SEK125,110 (US$13,640 or Euro14,810). Almost 45 percent of the direct costs were attributable to social services. Women had higher costs than men, and costs for survivors increased with age due to social services.Conclusions:With an incidence of 213 first-ever strokes per 100,000 individuals, the total excess direct and indirect cost of stroke would be SEK12.3 billion (approximately US$1.3 billion or Euro1.5 billion). Hence, there are large potential cost offsets both in the health-care sector and in the social service sector if the incidence of first-ever stroke could be reduced.

Abstract
BACKGROUND Informal care givers support disabled stroke patients at home but receive little training for the caregiving role. OBJECTIVE To evaluate the effectiveness of training care givers in reducing burden of stroke in patients and their care givers. DESIGN A single, blind, randomised controlled trial. SETTING Stroke rehabilitation unit. SUBJECTS 300 stroke patients and their care givers. INTERVENTIONS Training care givers in basic nursing and facilitation of personal care techniques. MAIN OUTCOME MEASURES Cost to health and social services, caregiving burden, patients' and care givers' functional status (Barthel index, Frenchay activities index), psychological state (hospital anxiety and depression score), quality of life (EuroQol visual analogue scale) and patients' institutionalisation or mortality at one year. RESULTS Patients were comparable for age (median 76 years; interquartile range 70-82 years), sex (53% men), and severity of stroke (median Barthel index 8; interquartile range 4-12). The costs of care over one year for patients whose care givers had received training were significantly lower (10,133 pounds sterling v 13,794 pounds sterling (18,087 dollars v 24,619 dollars; 15,204 euros v 20,697 euros); P = 0.001). Trained care givers experienced less caregiving burden (care giver burden score 32 v 41; P = 0.0001), anxiety (anxiety score 3 v 4; P = 0.0001) or depression (depression score 2 v 3; P = 0.0001) and had a higher quality of life (EuroQol score 80 v 70; P = 0.001). Patients' mortality, institutionalisation, and disability were not influenced by caregiver training. However, patients reported less anxiety (3 v 4.5; P < 0.0001) and depression (3 v 4; P < 0.0001) and better quality of life (65 v 60; P = 0.009) in the caregiver training group. CONCLUSION Training care givers during patients' rehabilitation reduced costs and caregiver burden while improving psychosocial outcomes in care givers and patients at one year.

Abstract
PURPOSE With the rapid international spread of interventions, there is a need to understand the economic implications of these changes and to interpret these economic implications on the international level. The purpose of this study is to systematically compare total health care expenditures on stroke, the costs of stroke per capita, and the distribution of stroke costs within different countries, with special attention to the allocation of resources among different health care facilities. METHODS Studies for this literature review were selected by conducting a literature search from January 1966 to July 2003. Key methodological, country-related, and monetary issues of the selected stroke cost studies were evaluated using a checklist. RESULTS After selection, 25 stroke cost studies were reviewed. Although the selected cost of illness studies used different methodologies, the estimated expenditures for stroke are approximately similar. The proportion of national health care in the 8 countries studied is unequivocal for the more recent studies, ie, approximately 3% of total health care expenditures. A shift is observed from the inpatient treatment costs (in the first year) toward outpatient treatment and long-term care costs (in the latter years). Furthermore, it is remarkable that in the studies, little attention is paid to costs borne by the patient and family or to the costs of comorbidity. CONCLUSIONS This study highlights the importance of studying the economic consequences of stroke and of interpreting the results on the international level. The results of stroke cost studies provide insight into the distribution of the costs of stroke and the impact of stroke on the national expenditure on health care.

Abstract
OBJECTIVES Stroke is a heavy economic burden on individuals, society, and health services in Japan, where health expenditures are rising rapidly. The objective of the present study was to examine medical services and demographic factors associated with increased inpatient charges for ischemic stroke in Japan. SUBJECTS AND METHODS The study subjects were 316 patients with a principal diagnosis of acute ischemic stroke who were discharged from the National Kyushu Medical Center Hospital from 1 July 1995 through 31 June 1999. Demographic, clinical, and administrative data were retrospectively collected from medical records and the hospital Clinical Financial Information System (CFIS). The influence of social and medical factors on total charges was analyzed using the stepwise multiple regression model. RESULTS Among the total subjects, the mean (median) length of hospital stay (LOHS) was 33 (30) days (range, 2-155 days). The mean (median) hospital charge per patient was US dollars 9020 (dollars 7974) with a range of dollars 336-54,509. The distribution of charges was 42% for fundamental, 17% for injection therapies, 13% for radiological test, 11% for other laboratory examinations, 3% for drugs, and 3% for operations. Stepwise multiple regression analysis revealed that LOHS was the key determinant of the hospital charge (partial R2=0.5993, P=0.0001). Operations (P=0.0001) and angiography (P=0.03) were also independent but less contributory determinants of the hospital charge. CONCLUSIONS LOHS was strongly, positively associated with inpatient charges for ischemic stroke in Japan. This implies that significant charge reductions are more likely to rely on shortening LOHS, which probably can be achieved by altering reimbursement policies.

Abstract
Clinicians commonly evaluate patients with thrombosis or a prolonged activated partial thromboplastin time (aPTT) for the presence of a lupus anticoagulant (LA). We evaluated strategies for detecting LA, in three clinical settings, with decision-modeling techniques. A decision tree was constructed with 12 strategies, using a combination of aPTT and dilute Russell viper venom times (dRVVT) with confirmatory tests, tissue thromboplastin time (TTI), platelet neutralization procedures, and mixing studies. Probabilities and costs of adverse events and test costs were obtained from the literature. Patient preference for each strategy was evaluated by assigning utilities to each outcome. On the basis of assay results in 90 healthy people and 77 patients, we calculated sensitivities and specificities for each strategy, with true positives defined as suggested by the International Society on Thrombosis and Haemostasis. The least costly strategy for evaluation of patients with a prolonged aPTT, or with thrombosis, is not to test and to assume that LA is absent. For patients with systemic lupus erythematosus (SLE), it is least expensive not to test, although testing with TTI alone can also be considered an efficient strategy. The strategy of highest utility to patients with SLE is testing with TTI, followed by dRVVT. On the basis of these cost and utility results, clinicians' strategies for detecting LA may need modification. These strategies would then optimally be tested in clinical trials.

Abstract
BACKGROUND AND PURPOSE Informal caregivers play an important role in the lives of stroke patients, but the cost of providing this care has not been estimated. The purpose of this study was to determine the nature and amount of informal care provided to stroke patients and to estimate the economic cost of that care. METHODS The primary caregivers of stroke patients registered in the North East Melbourne Stroke Incidence Study (NEMESIS) were interviewed at 3, 6, and 12 months after stroke, and the nature and amount of informal care provided were documented. The opportunity and replacement costs of informal care for all first-ever-in-a-lifetime strokes (excluding subarachnoid hemorrhages) that occurred in 1997 in Australia were estimated. RESULTS Among 3-month stroke survivors, 74% required assistance with activities of daily living and received informal care from family or friends. Two thirds of primary caregivers were women, and most primary caregivers (>90%) provided care during family or leisure time. Total first-year caregiver time costs for all first-ever-in-a-lifetime strokes were estimated to be A$21.7 million (opportunity cost approach) or A$42.5 million (replacement cost approach), and the present values of lifetime caregiver time costs were estimated to be A$171.4 million (opportunity cost approach) or A$331.8 million (replacement cost approach). CONCLUSIONS Informal care for stroke survivors represents a significant hidden cost to Australian society. Because our community is rapidly aging, this informal care burden may increase significantly in the future.

Abstract
OBJECTIVE Stroke places a huge burden on society in terms of premature death, disability, and costs of care. Increasingly, the cost-effectiveness of new interventions needs to be demonstrated before their widespread implementation. Clinical trials are unable to measure the long-term impact of such new interventions in stroke care, and a modeling approach is necessary. The Stroke Outcome Model has been developed in four countries: France, Germany, the United Kingdom, and the United States as a flexible tool for this purpose. METHOD The decision-analytic model represents the management of acute stroke and long-term care and prevention of recurrence for stroke survivors. The latter consists of semi-Markov state-transition processes, with health states defined by therapy, disability, and occurrence of further stroke. Sources of clinical data include trials, meta-analyses, and prospective cohort studies such as the Oxfordshire Community Stroke Project and the Northern Manhattan Stroke Study. Resource use data were obtained from published sources and expert clinician panels. Outcome measures used were strokes averted, life years, and quality-adjusted life-years gained. RESULTS The model has been used to undertake economic analyses of antiplatelet therapy for the prevention of recurrent strokes, and of stroke unit care and thrombolytic therapy in acute stroke. From a health- and social-care perspective, new interventions were found to be cost saving or to provide health benefits at modest additional cost. Results were sensitive to the cost perspective, time horizon, baseline risk of stroke recurrence, and choice of effectiveness measure. CONCLUSION The development of this model highlights the need for improved information on prognosis and resources used by stroke survivors and the importance of differentiating between economically distinct end points such as death, disabled survival and nondisabled survival, which may be combined as outcomes in clinical trials.

Abstract
OBJECTIVE Stroke is a heavy economic burden on the individuals, society and health services in China, where health expenditure is rising rapidly. The purpose of the present study is to examine health services and demographic factors associated with inpatient charges for cerebral infarction in China, focusing on hospital charges of insured and uninsured patients. METHODS The study subjects were 545 patients with a principal diagnosis of cerebral infarction stroke who were discharged from the China-Japan Friendship Hospital from January 1, 1997 through December 31, 1998. Demographic, clinical and administrative data were retrospectively collected from the medical record and financial database. The influence of social and medical factors on total charges was analyzed with stepwise multiple regression model. RESULTS Of 545 subjects, 429 (79%) were the insured patients and 116 (21%) were the uninsured patients. Length of hospital stay (LOHS) for the insured patients (median, 32 days) was significantly longer (P<0.001) than that for the uninsured (median, 23 days). The hospital charges per discharge for the insured was significantly higher (geometric mean, 10407 yuan) (P<0.0001) than that for the uninsured patients (geometric mean, 5857 yuan). With stepwise multiple regression, factors associated independently with the hospital charge were: longer hospital stay, insurance status, increased number of head magnetic resonance imaging (MRI) and computerized tomography (CT), infection in hospital stay, and more severe condition of stroke. CONCLUSIONS Inpatient charge for cerebral infarction stroke was positively associated with being the insured. The findings suggest an overuse of health care resources in insured patients and limited use of resources by those who are not.

Abstract
An international review of the costs of stroke was conducted to explore data sources, and cost variables as well as to compare estimates of the annual aggregated cost (prevalence-based) and total per patient long-term cost (incidence-based) of care. Dutch, English, French, German, Italian and Spanish literature was searched using the keywords stroke, ischaemic stroke, haemorrhagic stroke, cerebrovascular accident, cerebral infarction, cost(s), economics, and cost analysis. Criteria for study inclusion were: provides estimates of direct and/or indirect costs of stroke, published after 1989, methods described in adequate detail, and for studies of long-term costs, estimates based on a minimum 5 years of care following the event. Cost estimates are presented in original currencies and US dollars. Among studies representing Australia, New Zealand, Western Europe and North America, six prevalence studies reported total annual aggregated costs of US dollars 7,975 (1988 values) to US dollars 54,546 (1993 values) per patient; eight incidence-based studies reported total long-term per patient costs of US dollars 18,538 (1991 values) to US dollars 228,038 (1990 values). Identifiable factors underlying variation included: perspective employed, cost variables considered, and exclusion of comorbidities. Although lack of uniformity hampers inter-study comparisons, it is evident that stroke poses a significant economic burden. Consensus on standard cost variables and methods for projections of resource use and survival over time are clearly warranted.

Abstract
BACKGROUND AND PURPOSE Accurate information about resource use and costs of stroke is necessary for informed health service planning. The purpose of this study was to determine the patterns of resource use among stroke patients and to estimate the total costs (direct service use and indirect production losses) of stroke (excluding SAH) in Australia for 1997. METHODS An incidence-based cost-of-illness model was developed, incorporating data obtained from the North East Melbourne Stroke Incidence Study (NEMESIS). The costs of stroke during the first year after stroke and the present value of total lifetime costs of stroke were estimated. RESULTS The total first-year costs of all first-ever-in-a lifetime strokes (SAH excluded) that occurred in Australia during 1997 were estimated to be A$555 million (US$420 million), and the present value of lifetime costs was estimated to be A$1.3 billion (US$985 million). The average cost per case during the first 12 months and over a lifetime was A$18 956 (US$14 361) and A$44 428 (US$33 658), respectively. The most important categories of cost during the first year were acute hospitalization (A$154 million), inpatient rehabilitation (A$150 million), and nursing home care (A$63 million). The present value of lifetime indirect costs was estimated to be A$34 million. CONCLUSIONS Similar to other studies, hospital and nursing home costs contributed most to the total cost of stroke (excluding SAH) in Australia. Inpatient rehabilitation accounts for approximately 27% of total first-year costs. Given the magnitude of these costs, investigation of the cost-effectiveness of rehabilitation services should become a priority in this community.

Abstract
OBJECTIVES To estimate the short term event and cost consequences of achieving two smoking cessation targets for England among a cohort of 35-64 year olds, in terms of the number of hospitalised acute myocardial infarctions (AMIs) and strokes avoided. DESIGN A spreadsheet model based on previous work and using data for England was constructed to simulate the effects of achieving the target set out in the government's tobacco white paper (target 1). We also examined the consequence of achieving the intensive smoking reduction witnessed in California (target 2). RESULTS Target 1 would result in 347 AMI and 214 stroke hospitalisations avoided in the year 2000, and by 2010 this would be 6386 AMI and 4964 strokes avoided. Achieving target 2 would result in 739 AMI and 455 stroke hospitalisations avoided in 2000, and 14 554 AMI and 11 304 strokes avoided by 2010. Achieving target 1 would save pound524 million ( pound423 million discounted at a rate of 2.67% for stroke and 2.31% for AMI) and target 2 would save pound1.14 billion ( pound921 million discounted) in terms of National Health Service costs. CONCLUSION In the short term (11 years), reductions in the prevalence of smoking will produce sizeable reductions in both events and hospital costs.

Abstract
BACKGROUND AND PURPOSE [corrected] With the ever-increasing pressure on healthcare budgets, we witness a growing demand for evidence of the economic implications of care across many therapeutic areas. Stroke is no exception. METHODS Detailed information on healthcare use was collected in conjunction with two 12-week international trials designed primarily to assess the safety and efficacy of a new potential neuroprotective agent. The information was gathered prospectively by means of a customized resource use instrument that included both acute and long-term inpatient management as well as community care. In this report, the results pertaining to the 1341 acute ischemic stroke patients are described. RESULTS More than 70% of the mean cost ($13 668) was explained by the initial hospitalization, which averaged 24 days. The total cost and its components varied according to patient age, the presence of comorbidities, and several indicators of disease severity. Pronounced country differences could be observed in the management of this fairly homogeneous patient group. CONCLUSIONS This study provides a comprehensive picture of the healthcare services used for the treatment and rehabilitation of stroke victims, presented with respect to various patient and disease characteristics. It is expected that researchers evaluating the cost-efficiency of specific stroke treatments will benefit from the detailed information presented in this report.

Abstract
BACKGROUND AND PURPOSE Stroke is a debilitating disease with long-term social and economic consequences. As new therapies for acute ischemic stroke are forthcoming, there is an increasing need to understand their long-term economic implications. To address this need, a stroke economic model was created. METHODS The model consists of 3 modules. A short-term module incorporates short-term clinical trial data. A long-term module composed of several Markov submodels predicts patient transitions among various locations over time. The modules are connected via a bridge component that groups the survivors at the end of the short-term module according to their functional status and location. Examples of analyses that can be conducted with this model are provided with the use of data from 2 international trials. For illustration, UK unit costs were estimated. RESULTS With the trial data in the short-term module, the short-term management cost is estimated to be pound8326 (US $13,649 [USD]). Hospital stay was the major cost driver. By the end of the trials, there was a pronounced difference in the distribution of patient locations between functional groups. It is predicted in the long-term module that the subsequent cost amounts to pound75 985 (124,564 USD) for a major and pound27,995 (45,893 USD) for a minor stroke. CONCLUSIONS Linking functional recovery at the end of short-term treatment with patients' treatment and residential locations allows this model to estimate the long-term economic impact of stroke interventions. Using patient location instead of the more common natural history as the model foundation allows quantification of the long-term impact to become data driven and hence increases confidence in the results.

Abstract
OBJECTIVES To estimate the annual costs in Sweden of coronary heart disease (CHD) and stroke, and the potential cost savings if these clinical 'events' are avoided. The analysis is undertaken from a societal perspective, including both direct and indirect costs. Costs are calculated for five clinical conditions: (i) acute myocardial infarction (AMI), (ii) angina pectoris (AP), (iii) unstable angina (UA), (iv) congestive heart failure (CHF), and (v) stroke. DESIGN A retrospective study including patients admitted to the Department of Medicine at Södertälje Hospital during the period January 1993 to March 1995 with CHD or a stroke. Each patient was followed for 1 year after admission to the hospital. To estimate potential cost savings, the patient was used as his or her own control. The potential savings in direct costs if CHD or a stroke is avoided were estimated as the difference between costs for 1 year after and 1 year before the event. The indirect costs were calculated as the difference between the values of market production of goods and services the year before the event and the year after. SETTING The Department of Medicine at Södertälje Hospital, Södertälje, Sweden. SUBJECTS The patients included in the study were patients at the Department of Medicine at Södertälje Hospital in Sweden. The inclusion criterion was that the patients should have been admitted for the first time for CHD or stroke during the year 1994. To obtain 25 patients for each clinical category we first had to expand the inclusion period to cover January 1993 to March 1995. Secondly, we also had to include 36 patients with an earlier established uncomplicated CHD or stroke. Despite this, no more than 22 patients with UA were found. INTERVENTIONS Patients were followed in medical practice. MAIN OUTCOME MEASURES Costs, direct and indirect costs, and potential savings. RESULTS The mean direct costs during the year after a clinical event range between Swedish kronor (SEK) 41 000 for CHF and SEK 96 000 for stroke, whereas the mean potential savings in direct costs range from SEK 36 000 for CHF to SEK 91 000 for UA. The potential mean savings in indirect costs range between SEK 24 000 for CHF and SEK 102 000 for AMI. The direct costs for first-time patients are lower than those for patients with an earlier established CHD or stroke. No systematic differences have been found in potential direct cost savings and indirect costs between the two patient groups. CONCLUSIONS CHD and stroke are associated with high costs during the year after admission to the Department of Medicine. There are also large potential cost savings from the prevention of CHD and stroke. However, further studies, including more patients and costs arising in the municipality, are needed to establish more precise and complete estimates of the costs related to CHD and stroke.

Abstract
BACKGROUND AND PURPOSE There are few population-based data available regarding nursing home use after stroke. This study clarifies the use of a nursing home after stroke, as well as its dependence on stroke severity, in a defined population. METHODS All first stroke events among residents of Rochester, Minn, during 1987-1989 were ascertained, subtyped, and assigned Rankin disability scores (RS) before the event, at maximal deficit, and at specified intervals after stroke. Persons were followed from the date of stroke event to death, emigration from Rochester, or December 31, 1994, in complete community-based medical records and Minnesota Case Mix Review Program data tapes to determine nursing home residency before stroke and at 90 days and 1 year after stroke, proportion of survival days in a nursing home, and cumulative risk of admission to a nursing home. RESULTS There were 251 cases of first cerebral infarction, 24 intracerebral hemorrhages, and 15 subarachnoid hemorrhages among residents of Rochester during 1987-1989. The maximal deficit RS was 1 or 2 for 62 (25%), RS 3 for 72 (29%), and RS 4 or 5 for 117 (47%) of the cerebral infarct patients. Among patients surviving to 90 days or 1 year after cerebral infarction, 25% were in nursing home at 90 days and 22% at 1 year, respectively. Within these maximal deficit RS categories, the percentages of follow-up time spent in a nursing home during the first post-cerebral infarction year are as follows: RS 1 to 2, 4%; RS 3, 10%; and RS 4 to 5, 54%. Multivariate logistic regression revealed that increasing age and RS 4 to 5 at maximal deficit were independent predictors (P<0.0001) of nursing home residency at 90 days and 1 year after stroke, whereas stroke type was not an independent predictor. At 1 year after cerebral infarction, the Kaplan-Meier estimates of proportion of people with at least 1 nursing home admission were 11% for RS 1 to 2, 22% for RS 3, and 68% for RS 4 to 5. CONCLUSIONS This study provides unique population-based data regarding the short- and long-term use of a nursing home after stroke and its dependence on stroke severity. More than 50% of people with a severe cerebral infarction are in a nursing home 90 days and 1 year after the stroke, and by 1 year, nearly 70% will have required some nursing home stay. Age and stroke severity are independent predictors of nursing home residency after stroke.

Abstract
BACKGROUND The NNT (number needed to treat) and NNH (number needed to harm) are useful in conveying the results of clinical trials because they emphasize the effort that must be expended to accomplish a single, tangible outcome. But NNT conveys the effort required to achieve a positive outcome without distinguishing between the presence or absence of treatment-related adverse events. Similarly, NNH conveys harm without accounting for the achievement or lack of achievement of the benefit of therapy. Consequently, a mathematical model was developed to extend the NNT and NNH to represent the effort required to achieve "unqualified success" (NNTUS, treatment success without treatment-induced side effects) and "unmitigated failure" (NNHUF, lack of treatment success with treatment-induced side effects). METHODS AND RESULTS NNTUS was calculated by adjusting the absolute risk reduction to allow for the probability of not incurring a treatment-related adverse event. NNHUF was similarly calculated by adjusting the absolute risk of incurring a treatment-related adverse event by the probability of not incurring any treatment-related benefit. The impact of conveying clinical trial data by the use of NNT, NNTUS, NNH, and NNHUF is illustrated by means of 11 highly cited trials identified systematically from the cardiovascular literature. The treatment effort measured by the NNTUS and the NNHUF was consistently higher than that given by the traditional NNT and NNH. These increments ranged from 1% to several hundred percent. CONCLUSIONS The NNTUS and the NNHUF represent the treatment effort required on average to achieve 1 unqualified success and 1 unmitigated failure. NNTUS and NNHUF balance benefit and harm in an objective way and are relevant for making service delivery decisions.

Abstract
OBJECTIVE To evaluate the safety and cost effectiveness of carotid surgery performed altering the perioperative protocol in an attempt to decrease resource utilisation. SETTING Department of vascular surgery in a large metropolitan teaching hospital in northern Italy. DESIGN Prospective, non-selective study. MATERIALS AND METHODS Three hundred and eighty carotid procedures were performed in 1995 on 343 patients (274 males, 69 females, mean age 68.2 years, range 47-86 years). The most important cost containment measures, were: (i) limiting the use of contrast arteriography to cases of dubious ultrasonographic diagnosis; (ii) routine use of loco-regional anaesthesia; (iii) postoperative admission to an intensive care unit (ICU) only in selected cases; (iv) early postoperative discharge where possible. RESULTS Mortality was 0.26% and neurological morbidity 1.58%. General anaesthesia was required in eight patients (2.1%), and only seven patients (1.8%) were admitted postoperatively to the ICU. Arteriography was performed in 56 cases (14.7%). The average hospital stay was 5 days with a global cost of 43,036 ECU, as compared with a cost of 6764 ECU for patients treated traditionally with routine arteriography, general anaesthesia and routine ICU admission. CONCLUSIONS Selective use of arteriography and ICU, routine use of loco-regional anaesthesia and reduced hospital stay make it possible to lower the cost of carotid surgery without sacrificing quality.

Abstract
BACKGROUND AND PURPOSE Stroke represents a major economic challenge to society. The direct cost of stroke is largely determined by the duration of hospital stay, but internationally applicable estimates of the direct cost of acute stroke care and rehabilitation on cost-efficient stroke units are not available. Information regarding social and medical factors influencing the length of hospital stay (LOHS) and thereby cost is needed to direct cost-reducing efforts. METHODS We determined the direct cost of stroke in the prospective, consecutive, and community-based stroke population of the Copenhagen Stroke Study by measuring the total LOHS in the 1197 acute stroke patients included in the study. All patients had all their acute care and rehabilitation on a dedicated stroke unit. Neurological impairment was measured by the Scandinavian Stroke Scale. Local nonmedical factors affecting the LOHS, such as waiting time for discharge to a nursing home after completed rehabilitation, were accounted for in the analysis. The influence of social and medical factors on the LOHS was analyzed in a multiple linear regression model. RESULTS The average LOHS was 27.1 days (SD, 44.1; range, 1 to 193), corresponding to a direct cost of $12.150 per patient including all acute care and rehabilitation. The LOHS increased with increasing stroke severity (6 days per 10-point increase in severity; P < .0001) and single marital status (3.4 days; P = .02). Death reduced LOHS (22.0 days; P < .0001). Age, sex, diabetes, hypertension, claudication, ischemic heart disease, atrial fibrillation, former stroke, other disabling comorbidity, smoking, daily alcohol consumption, and the type of stroke (hemorrhage/infarct) had no independent influence on LOHS. CONCLUSIONS Acute care and rehabilitation of unselected patients on a dedicated stroke unit takes on average 4 weeks. In general, comorbidity such as diabetes or heart disease does not increase LOHS. Efforts to reduce costs should therefore aim at reducing initial stroke severity or improving the rate of recovery.

Abstract
PURPOSE The purpose of this study was to determine the cost-effectiveness of carotid endarterectomy for treating asymptomatic patients with > or = 60% internal carotid stenosis, based on outcomes reported in the Asymptomatic Carotid Atherosclerosis Study (ACAS). METHODS A cost-effectiveness analysis was performed using a Markov decision model in which the probabilities for base-case analysis (average age, 67 years; 66% male; perioperative stroke plus death rate, 2.3%; ipsilateral stroke rate during medical management, 2.3% per year) were based on ACAS. The model assumed that patients who had TIAs or minor strokes during medical management crossed over to surgical treatment, and used the NASCET data to model the outcome of these now-symptomatic patients. Average cost of surgery ($8500), major stroke ($34,000 plus $18,000 per year), and other costs were based on local cost determinations plus a review of the published literature. Cost-effectiveness was calculated as the incremental cost of surgery per quality-adjusted life year (QALY) saved when compared with medical treatment, discounting at 5% per year. Sensitivity analysis was performed to determine the impact of key variables on cost-effectiveness. RESULTS In the base-case analysis, surgical treatment improved quality-adjusted life expectancy from 7.87 to 8.12 QALYs, at an incremental lifetime cost of $2041. This yielded an incremental cost-effectiveness ratio of $8,000 per QALY saved by surgical compared with medical treatment. The high cost of care after major stroke during medical management largely offset the initial cost of endarterectomy in the surgical group. Furthermore, 26% of medically managed patients eventually underwent endarterectomy because of symptom development, which also decreased the cost differential. Sensitivity analysis demonstrated that the relative cost of surgical treatment increased substantially with increasing age, increasing perioperative stroke rate, and decreasing stroke rate during medical management. CONCLUSION For the typical asymptomatic patient in ACAS with > or = 60% carotid stenosis, our results indicate that carotid endarterectomy is cost-effective when compared with other commonly accepted health care practices. Surgery does not appear cost-effective in very elderly patients, in settings where the operative stroke risk is high, or in patients with very low stroke risk without surgery.

Abstract
The aim of this study was to evaluate the selection criteria and characteristics of the patients who have access to rehabilitation facilities after having experienced an acute stroke. Between January 1993 and February 1994, 383 patients were recruited in 13 hospitals in Lombardy, and telephonically followed up four months after study entry. The data were collected by members of the Associazione Volontari Ospedalieri (Hospital Volunteers' Association). The 4-month mortality rate was 23%. The primary selection criterion for gaining access to rehabilitation facilities was the degree of disability; the secondary factor was age. Rehabilitation facilities were not available to very severely afflicted or self-sufficient patients, but were preferentially made available to young, partially-dependent patients. A rehabilitative intervention within the first month was made available to fewer than 50% of the patients for whom it was indicated. The absence of care for elderly patients and the delay in its availability for those who actually receive it underline the need for new organisational methods. The data presented here also show that voluntary associations can work as observers of the health service. A more complete study is required in order to understand the real dimensions of the problem and the clinical and social characteristics of the population involved.

Abstract
The aim of this study was to find out how stroke patients conceived their life situation within the first week of the acute care phase as seen from the nurses' viewpoint. Six patients were interviewed within 3 weeks from their first stroke, using questions based on a holistic philosophy and analysed with the phenomonographic approach. Two main categories emerged from the results: the feeling of unreality and the awareness of a changed role in life, together with six subcategories; feeling of a changed perception of the body; feeling of being confused; loss of capability; awareness of confined life space; the importance of support and encouragement; and the will to look for new opportunities. The study concludes that the body change resulting from a stroke leads to both physical and psychological trauma, in which the psychological crisis can be very deep and best described as a personal catastrophe. The patient's capability to receive and understand information becomes blocked, which influences both the nurse and the patient's next of kin with regard to their care of the patient. Conversations with the patient must be frequent so that the acute care can be evaluated and agreement reached between the patient's wishes and the nurses' objectives. The results indicate the significance of intervention programmes based on crisis theory within the first week of a stroke event.

Abstract
BACKGROUND AND PURPOSE Stroke causes high morbidity and mortality. The aging of the population further increases the demands on healthcare costs. METHODS We estimated the lifetime direct costs of care of first-ever stroke patients in the Netherlands in 1991 using epidemiological data from national and international studies. In addition, we examined the effect of an aging population on future healthcare costs. RESULTS The lifetime costs for 24,007 first-ever stroke patients are estimated to be 1870 million Dutch guilders (Dfl) (1 Dfl = 0.53 US dollar, 1991). Per-person costs are higher for women (83,000 Dfl) than for men (71,000 Dfl). The major cost component of first-year costs is hospital costs (45%), while nursing home costs dominate lifetime costs (50%). An increase of the elderly population older than 65 years of 27% between 1991 and 2010 might lead to a parallel increase of total costs of 30%, or 1.5% per year. CONCLUSIONS Long-term care rather than acute care dominates the lifetime costs for stroke patients now and in the future.

Abstract
Cost-effectiveness analysis uses both economic and clinical outcomes data to evaluate treatment options. In this era of economic constraints on health care, treatments that are not cost-effective will increasingly be denied public and private insurance reimbursement. The authors used mathematical modeling techniques to assess the cost-effectiveness of elective surgery for the treatment of asymptomatic, unruptured, intracranial aneurysms. Input values for the Markov model used in this study were determined from both the literature and clinical judgment. Direct medical costs for hospitalization and physician fees were derived from Medicare cost reports and resource-based relative-value units, expressed in 1992 U.S. dollars. Costs and benefits were discounted at an annual rate of 5%. Using baseline model assumptions for a 50-year-old patient, elective aneurysm surgery provides an average of 0.88 additional quality-adjusted life years (QALYs) compared with nonsurgical treatment. However, prompt elective surgery ($23,300) costs more than expectant management ($2100), in which only patients whose aneurysms rupture incur treatment costs. Combining the outcomes and cost data, the incremental cost-effectiveness of elective aneurysm surgery is $24,200 per QALY, which is comparable to other accepted medical or surgical interventions, such as total knee arthroplasty ($15,200/QALY) or antihypertensive therapy in a 50-year-old patient ($29,800/QALY). Prompt elective surgery for asymptomatic, unruptured, intracranial aneurysms is recommended as a cost-effective use of medical resources provided: 1) surgical morbidity and mortality remain at reported levels; 2) the patient has a life expectancy of at least 13 additional years; and 3) the patient experiences a decrease in quality of life from knowingly living with an unruptured aneurysm.

Abstract
BACKGROUND AND PURPOSE Indications for carotid endarterectomy have engendered considerable debate among experts and have resulted in publication of retrospective reviews, natural history studies, audits of community practice, position papers, expert opinion statements, and finally prospective randomized trials. The American Heart Association assembled a group of experts in a multidisciplinary consensus conference to develop this statement. METHODS A conference was held July 16-18, 1993, in Park City, Utah, that included recognized experts in neurology, neurosurgery, vascular surgery, and healthcare planning. A program of critical topics was developed, and each expert presented a talk and provided the chairman with a summary statement. From these summary statements a document was developed and edited onsite to achieve consensus before final revision. RESULTS The first section of this document reviews the natural history, methods of patient evaluation, options for medical management, results of surgical management, data from position statements, and results to date of prospective randomized trials for symptomatic and asymptomatic patients with carotid artery disease. The second section divides 96 potential indications for carotid endarterectomy, based on surgical risk, into four categories: (1) Proven: This is the strongest indication for carotid endarterectomy; data are supported by results of prospective contemporary randomized trials. (2) Acceptable but not proven: a good indication for operation; supported by promising but not scientifically certain data. (3) Uncertain: Data are insufficient to define the risk/benefit ratio. (4) Proven inappropriate: Current data are adequate to show that the risk of surgery outweighs any benefit. CONCLUSIONS Indications for carotid endarterectomy in symptomatic good-risk patients with a surgeon whose surgical morbidity and mortality rate is less than 6% are as follows. (1) Proven: one or more TIAs in the past 6 months and carotid stenosis > or = 70% or mild stroke within 6 months and a carotid stenosis > or = 70%; (2) acceptable but not proven: TIAs within the past 6 months and a stenosis 50% to 69%, progressive stroke and a stenosis > or = 70%, mild or moderate stroke in the past 6 months and a stenosis 50% to 69%, or carotid endarterectomy ipsilateral to TIAs and a stenosis > or = 70% combined with required coronary artery bypass grafting; (3) uncertain: TIAs with a stenosis < 50%, mild stroke and stenosis < 50%, TIAs with a stenosis < 70% combined with coronary artery bypass grafting, or symptomatic, acute carotid thrombosis; (4) proven inappropriate: moderate stroke with stenosis < 50%, not on aspirin; single TIA, < 50% stenosis, not on aspirin; high-risk patient with multiple TIAs, not on aspirin, stenosis < 50%; high-risk patient, mild or moderate stroke, stenosis < 50%, not on aspirin; global ischemic symptoms with stenosis < 50%; acute dissection, asymptomatic on heparin. Indications for carotid endarterectomy in asymptomatic good-risk patients performed by a surgeon whose surgical morbidity and mortality rate is less than 3% are as follows. (1) Proven: none. As this statement went to press, the National Institute of Neurological Disorders and Stroke issued a clinical advisory stating that the Institute has halted the Asymptomatic Carotid Atherosclerosis Study (ACAS) because of a clear benefit in favor of surgery for patients with carotid stenosis > or = 60% as measured by diameter reduction. When the ACAS report is published, this indication will be recategorized as proven. (2) acceptable but not proven: stenosis > 75% by linear diameter; (3) uncertain: stenosis > 75% in a high-risk patient/surgeon (surgical morbidity and mortality rate > 3%), combined carotid/coronary operations, or ulcerative lesions without hemodynamically significant stenosis; (4) proven inappropriate: operations with a combined stroke morbidity and mortality > 5%.

Abstract
Initial functional ability (Barthel Index, mean 57) was found to be an important predictor of functional ability 1 year after stroke (mean 80) and for costs during the period. On average the total cost for a stroke patient was about SEK 200,000; the main expense, accommodation, averaged about SEK 140,000, while assistive devices amounted to SEK 2,600. Those who use assistive devices, although having achieved a high functional ability, perceive and rate their life situation (Nottingham Health Profile) considerably more impaired than those without assistive devices.

Abstract
BACKGROUND AND PURPOSE Cost-effectiveness analyses of stroke management are hampered by paucity of economic data. We made an update of the direct and indirect costs of stroke in Sweden (population, 8.5 million). METHODS Direct costs (ie, the costs for hospital and outpatient care and social services) were estimated on the basis of two prospective population-based studies of stroke and of two nationwide cross-sectional inventories of bed-days and diagnoses. Indirect costs (ie, the costs for loss of productivity and early retirement) were based on official statistics. RESULTS The direct annual costs of care for stroke patients in 1991 equaled 7836 million Swedish krona (SKr) ($1306 million in US dollars), and the indirect costs, 2430 million SKr ($405 million). The cost of stroke care was 1208 SKr ($201) per inhabitant in Sweden. The expected direct costs per patient from first stroke to death were 440,000 SKr ($73,333). When prestroke costs for other diseases and advanced age were subtracted, the sum was reduced to 180,000 SKr ($30,000). CONCLUSIONS Costs for hospital and outpatient care and social services accounted for 76% of Swedish stroke costs and for 24% of costs for loss of production and early retirement. Only 41% of direct costs were stroke-related.

Abstract
BACKGROUND AND PURPOSE Stroke cost consumes a large proportion of the gross domestic product in all developed countries, and while health care costs are rising, the ability to contain them is diminishing. METHODS We calculated the cost of acute stroke care for all first admissions to a teaching hospital in Toronto, Canada, in 1991 through 1992 for 285 consecutive patients. RESULTS The average cost per patient was $27,500 Canadian, and strokes in men cost less than in women ($23,000 versus $32,000 Canadian), for a total cost of $8 million Canadian over 2 years. More women died than men (34% versus 17%, P < .02), mainly from systemic complications of stroke, but because women stayed hospitalized longer, they cost more in the long term. The major factor determining cost was social support, and more men than women went home or to rehabilitation units (P < .02). Family support was greater for men (82%) than women (39%, P < .0002). CONCLUSIONS Significant cost reductions are more likely to be achieved by altering discharge policies and improving social conditions for early return to the home than by reducing laboratory or medical personnel costs.

Abstract
OBJECTIVE To assess the potential effects of primary prevention with anticoagulants or aspirin in atrial fibrillation on Swedish population. DESIGN Analysis of cost effectiveness based on the following assumptions: about 83,000 people have atrial fibrillation in Sweden, of whom 22,000 would be potential candidates for treatment with anticoagulants and 55,000 for aspirin treatment; the annual 5% stroke rate is reduced by 64% (with anticoagulants) and 25% (with aspirin); incidence of intracranial haemorrhage of 0.3%, 1.3%, or 2.0% per year; direct and indirect costs of a stroke of Kr180,000 and Kr90,000; estimated annual cost of treatment is Kr5030 for anticoagulants and Kr100 for aspirin. SETTING Total Swedish population. MAIN OUTCOME MEASURES Direct and indirect costs of stroke saved, number of strokes prevented, and cost of preventive treatment. RESULTS Depending on the rate of haemorrhagic complications 34 to 83 patients would need to be treated annually with anticoagulants to prevent one stroke; 83 patients would need to be treated with aspirin. Giving anticoagulant treatment only would reduce costs by Kr60 million if the incidence of intracranial haemorrhage were 0.3% but would imply a net expense if the complication rate exceeded 1.3%. The total savings from giving anticoagulant (22,000 patients) and aspirin (55,000 patients) treatment would be Kr175 million per year corresponding to 2 million pounds per million inhabitants each year. CONCLUSIONS Treatment with anticoagulants and, if contraindications exist, with aspirin is cost effective provided that the risk of serious haemorrhage complications due to anticoagulants is kept low.
