Abstract
Encouraging innovations should be a concern of the providers/gatekeepers of health-care if lower health-care costs are to become a reality. Controlled prices and improper incentives will dramatically slow innovation in American medicine. For the vertically integrated health-care system providing capitated coverage, the aggressive treatment of stroke is a sound financial decision.

Abstract
Intraaortic balloon counterpulsation (IABP) has been shown to improve coronary artery patency and reduce the rates of recurrent myocardial ischemia and its sequelae in selected patients when used within 24 hours of acute myocardial infarction. The economic implications of prophylactic IABP use are unknown. We obtained hospital bills for 102 patients enrolled in the Randomized IABP Trial (56%) and converted charges to costs using each hospital's Medicare cost report. In-hospital costs for patients who had 48 hours of IABP were compared with those of patients who did not. The costs of angiographic and clinical complications were determined. Small differences in clinical and angiographic characteristics existed between patients in the economic substudy and the overall population, but overall angiographic and clinical outcomes were comparable. Costs for patients who had IABP versus control patients were similar: mean $22,357 +/- $14,369 versus $19,211 +/- $8,414, median (25th and 75th percentiles) $17,903 ($15,787, $22,147) versus $17,913 ($15,144, $21,433), p = 0.45. Hospital costs were higher with the development of recurrent ischemia: mean $23,125 +/- $7,690 versus $20,416 +/- $12,449, median $21,069 ($17,896, $26,885) versus $17,492 ($14,892, $20,998) p = 0.02. Patients who had an adverse clinical event (death, stroke, reinfarction, and emergency revascularization) also had higher hospital costs: mean $25,598 +/- $10,024 versus $19,790 +/- $12,045, median $21,877 ($18,380, $28,049) versus $17,364 ($14,773, $20,779), p = 0.002. The prophylactic use of IABP in patients at high risk of infarct artery reocclusion within 24 hours of acute myocardial infarction provides sustained clinical benefit without substantially increasing hospital costs.

Abstract
The relationship between death from cerebrovascular disease and the levels of magnesium and calcium in drinking water was examined using an ecological design. The study area consisted of 227 municipalities in Taiwan. Data on the levels of magnesium and calcium in drinking water have been collected from the Taiwan Water Supply Corporation (TWSC). These levels of magnesium and calcium were compared using the standardized mortality ratios (SMRs) for cerebrovascular disease (1981-1990). A statistically significant inverse relationship was present between cerebrovascular mortality and levels of both magnesium and calcium after adjusting for urbanization index. After adjustment for calcium levels in drinking water and urbanization index, the weighted multivariate-adjusted regression coefficient indicated a decrease of 0.248 in the standardized mortality ratios (SMRs) for every 100 mg/L increase in magnesium levels in drinking water. The results from this study strengthen the hypothesis that magnesium in drinking water helps to prevent death from cerebrovascular disease.

Abstract
OBJECTIVE To assess whether outcomes and costs differ for elderly patients admitted to rehabilitation hospitals, subacute nursing homes, and traditional nursing homes. DESIGN Inception cohort stratified by provider type and followed prospectively for 6 months. SETTING A total of 92 hospital-based units and freestanding facilities from 17 states. PATIENTS A total of 518 randomly selected patients with hip fracture and 485 stroke patients admitted from November 1991 to February 1994. MAIN OUTCOME MEASURES At 6 months comparing community residence, recovery to premorbid levels in 5 activities of daily living (ADLs), Medicare costs, and the number of therapy and physician visits. Outcomes were adjusted for premorbid residence and function, caregiver availability, comorbid illness, admission function, cognition, depression, sensory deficits, and mobility impairments. RESULTS On admission, rehabilitation hospital patients were more likely (P<.001) to have caregivers and better cognitive and physical function. Hip fracture patients admitted to rehabilitation hospitals did not differ from patients admitted to nursing homes in returning to the community (adjusted odds ratio [OR], 1.3; 95% confidence interval [CI], 0.6-2.6) or in the number of ADLs recovered to premorbid level (difference, 0.09 ADL; 95% CI, -0.27-0.44), but stroke patients admitted to rehabilitation hospitals were more likely to return to the community (adjusted OR, 3.3; 95% CI, 1.5-7.2) and recover ADLs (difference, 0.63 ADL; 95% CI, 0.20-1.07). Subacute nursing home patients with stroke were more likely than traditional nursing home patients to return to the community (adjusted OR, 6.8; 95% CI, 2.2-21.4), there was no difference in return to the community for patients with hip fracture (adjusted OR, 1.6; 95% CI, 0.7-3.6), and there were no differences in recovery of ADLs for either condition. Medicare costs were greater (P<.001) for rehabilitation hospital patients than for subacute nursing home patients, and the costs for subacute nursing home patients were greater (P=.03 for stroke and .009 for hip fracture) than for traditional nursing home patients. CONCLUSIONS Study findings are consistent with enhanced outcomes for elderly patients with stroke treated in rehabilitation hospitals but not for patients with hip fracture. Subacute nursing homes were more effective than traditional nursing homes in returning patients with stroke to the community, despite comparable functional outcomes.

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
High-risk strategies represent important preventive measures that focus on individuals with a defined high risk of suffering a chronic disease. They are valuable in addition to measures of prevention within the general population. One example for a high-risk approach for stroke prevention is the treatment of hypertension in individuals that have previously suffered a transient ischemic attack (TIA). Data from the Klosterneuburg Stroke Data Bank and other sources enable an estimate of 2000 TIAs occurring in Austria each year, half of them being hypertensives that are mostly not treated or not sufficiently treated for their hypertension. A high-risk programme that implies forced and effective treatment of hypertension would prevent some 400 strokes or 3% of 16,000 first-ever strokes per year. Costs for preventing one stroke by means of Betablocker agents would amount to ATS 3500 and by ACE-inhibitor agents ATS 11,500, respectively. In addition to general preventive measures, such a programme would have an important impact on stroke incidence and public health.

Abstract
Recent studies have shown that carotid endarterectomy for significant lesions lowers the risk of stroke and also reduces medical costs by averting the high costs of strokes. However, there has been no information on the cost effect of duplex ultrasound examination which has evolved as the prime means of discovering these carotid lesions. This study reviewed the findings and management of 100 consecutive new patients referred for duplex ultrasound management of the carotid arteries and the cost effects resulting. Seventy-three patients with < 70% stenosis were managed non-operatively; the remaining 27 with 33 lesions producing > 70% stenosis were treated by carotid endarterectomy. It was estimated that 6.5 patients would have had a stroke within 18 months if not operated on. While the medical costs of these strokes would have been $958,838, the cost of avoiding them was $300,494; the result was a significant medical costs saving of $658,344.

Abstract
BACKGROUND AND PURPOSE Despite growing concern over the large numbers of specialists in the United States, little information is available on how stroke treatment varies by the specialty of the attending physician. This study compares the costs and outcomes of acute stroke patients by physician specialty, especially between neurologists and other specialists. METHODS We selected a random sample of Medicare patients aged 65 years and older admitted with cerebral infarction between January 1 and September 30, 1991, identified from the principal diagnosis on Medicare Provider Analysis and Review records. All Medicare claims for these patients were extracted from the date of admission through 90 days. The attending physician was identified as that physician billing for routine hospital visits during the first 7 days of the stay. RESULTS Neurologists treating stroke patients were significantly more expensive than other physicians but obtained better outcomes. Ninety-day mortality rates for patients treated by neurologists were significantly lower than those for other specialists. These cost and outcome differences persisted even after adjustment for patient age, comorbidity, hospital teaching status, and other characteristics. Compared with other attending physicians, neurologists were significantly more likely to order diagnostic cerebrovascular tests (especially brain MRI scans), more likely to prescribe warfarin, and more likely to discharge patients to inpatient rehabilitation facilities. CONCLUSIONS Systematic triaging to neurologists based on clinical characteristics unmeasured by administrative data might explain these observed differences between neurologists and other physicians. Alternatively, these specialists may have been better able to identify the mechanism of stroke, information that then affected the course of treatment. Given current pressures to substitute generalists for specialists, however, more research is needed on these stroke treatment differences.

Abstract
BACKGROUND AND PURPOSE Stroke is a common disease with a yearly cost in the United States of approximately $30 billion. The increasing prevalence of managed care and cost-containment measures may affect the delivery of stroke care now and in the future. This study was performed to determine (1) hospital charges and test utilization for stroke patients and (2) the effectiveness of educational efforts in modifying test utilization and related hospital charges. METHODS Patients with a diagnosis of stroke who were discharged from either the neurology service or another service of the Department of Medicine (DOM) were identified. Data on test utilization and hospital charges were collected and analyzed. Following this analysis, educational sessions were held in an effort to reduce the use of specific diagnostic tests. The effectiveness of these methods was studied in a second group of stroke patients. RESULTS In the baseline period there were 303 stroke patients, of which 262 (86%) were discharged from the neurology service and 41 (14%) were discharged from other services of the DOM. Patients on the neurology service had a lower mean length of stay than patients on the other services of the DOM (9.2 days versus 10.5 days) and lower mean total charges per case ($13,149 versus $15,727), although the respective differences were not statistically significant. Patient on the neurology service were more likely to have both brain CT and MRI performed (82 of 262 patients, 31.3%) than patients on the other services of the DOM (4 of 41, 9.8%, P = .005). In addition, patients on the neurology service were more likely to undergo a transthoracic echocardiogram than patients on the other services of the DOM (71.8% versus 53.7%, P = .025). After educational sessions, the percentage of stroke patients on the neurology service having both CT and MRI fell from 31.3% to 17.7% (P = .005), and the number of stroke patients having a transthoracic echocardiogram fell from 71.8% to 60.3% (P = .025). However, the overall charges for stroke patients on the neurology services did not decrease. CONCLUSIONS Education can be successful in reducing the utilization of and associated charges for specific diagnostic tests for some stroke patients. A multidisciplinary approach to case management, using tools such as care maps, may be necessary to realize significant cost savings in certain groups of stroke patients.

Abstract
BACKGROUND AND PURPOSE Stroke imposes a substantial economic burden on individuals and society. This study estimates the lifetime direct and indirect costs associated with the three major types of stroke: subarachnoid hemorrhage (SAH), intracerebral hemorrhage (ICH), and ischemic stroke (ISC). METHODS We developed a model of the lifetime cost of incident strokes occurring in 1990. An epidemiological model of stroke incidence, survival, and recurrence was developed based on a review of the literature. Data on direct cost of treating stroke were obtained from Medicare claims data, the 1987 National Medical Expenditure Survey (NMES), and insurance claims data representing a group of large, self-insured employers. Indirect costs (the value of foregone market and nonmarket production) associated with premature morbidity and mortality were estimated based on data from the US Bureau of Economic Analysis and the 1987 NMES. RESULTS The lifetime cost per person of first strokes occurring in 1990 is estimated to be $228,030 for SAH, $123,565 for ICH, $90,981 for ISC, and $103,576 averaged across all stroke sub-types. Indirect costs accounted for 58.0% of lifetime costs. Aggregate lifetime cost associated with an estimated 392,344 first strokes in 1990 was $40.6 billion: $5.6 billion for SAH, $6.0 billion for ICH, and $29.0 billion for ISC. Acute-care costs incurred in the 2 years following a first stroke accounted for 45.0%, long-term ambulatory care accounted for 35.0%, and nursing home costs accounted for 17.5% of aggregate lifetime costs of stroke. CONCLUSIONS The lifetime cost of stroke varies considerably by type of stroke and entails considerable costs beyond the first 2 years after a stroke.

Abstract
BACKGROUND Although the value of carotid endarterectomy has been proven, postoperative surveillance remains controversial. The purpose of this study was to determine the natural history of disease progression in the contralateral carotid artery by duplex surveillance, and to assess the cost of stroke prevention on this contralateral side. METHODS Vascular laboratory records were reviewed to identify carotid endarterectomy patients who had two or more duplex studies between 1984 and 1995. Critical stenosis was defined as > or = 75% area reduction. RESULTS In all, 324 patients were followed up with duplex scans for 1 month to 11 years (mean 30.3 months). The only factors that correlated with progression to critical stenosis were age and initial stenosis. Overall, 19.5% of patients progressed to critical stenosis within 5 years while the high-risk groups with age > 65 years or initial stenosis > or = 50% progressed to critical disease in 27% and 39%, respectively (P < or = 0.05). The cost per stroke prevented ranged from $143,500 to $418,200 when stratified by initial stenosis. CONCLUSION Patients who have undergone a carotid endarterectomy demonstrate a propensity for progression of carotid stenosis in the unoperated (contralateral) artery. The cost/benefit ratio may be improved by varying the intensity of duplex surveillance of the contralateral carotid based on the patient's age and initial degree of stenosis.

Abstract
OBJECTIVES This study examines the poststroke rehabilitation experience for a 20% sample of Medicare patients age 65 years and older admitted to an acute-care hospital with a stroke diagnosis during the 6-month interval, January 1, 1991 to June 30, 1991. Their Medicare claims data are used for two purposes: to identify current poststroke rehabilitation practice in the US population age 65 years and older, and to evaluate the importance of practice variation within this population. METHODS Regarding the first objective, the authors develop estimates for many poststroke rehabilitation use and cost parameters that formerly were unmeasured. With respect to the second objective, the authors construct and compare average service use rates across all stroke patients in a census division and across all stroke patients residing in the 30 largest metropolitan statistical areas. RESULTS The authors' Medicare claims analysis indicates that 73% of stroke survivors received either postacute institutional or ambulatory rehabilitation care during the first 6 months poststroke. The published stroke literature, on the other hand, focuses on the minority of stroke survivors, 16.5% in the Medicare data, who were admitted to an inpatient rehabilitation hospital. Regarding the second study objective, the Medicare analysis provides graphic evidence that poststroke rehabilitation practice varies substantially from one geographic area to another and that practice differences translate into large geographic-related differences in the cost of poststroke rehabilitation. CONCLUSIONS The authors believe the findings demonstrate a problem with inconsistent poststroke rehabilitation practice.

Abstract
BACKGROUND AND PURPOSE A large community hospital implemented an acute stroke program to respond to stroke patients in a consistent, systematic, and efficient manner. The primary objectives were to monitor the care delivered, improve the quality of care, and move the patients through their initial hospital stay in a timely manner. METHODS Acute stroke standing orders were developed, with a critical path developed on the basis of these orders and an expected length of stay. A multidisciplinary team began the rehabilitation process early in the hospital stay, monitored patient progress and length of stay, and provided appropriate discharge placement. Retrospective chart reviews were performed over a 4-year period, and the data were collated on a yearly basis. RESULTS Over a 4-year period, 414 Medicare patients demonstrated a steady decline of initial hospital length of stay from 7.0 to 4.6 days. During this same period of time, there was a decline in total hospital charges from $14,076 to $10,740 per patient. This represented a total dollar savings in charges of $1,621,296 (approximately $453,000 per year). The mortality rate for 1994 was 4.6%, with 46.5% of survivors discharged to home, 16.9% to acute rehabilitation, and 32.6% to nursing homes. CONCLUSIONS The implementation of a multidisciplinary acute stroke program decreased length of stay and hospitalization costs of Medicare patients.

Abstract
We estimated the hospital costs for patients with different cerebrovascular events and applied patient and administrative variables to explain the variance of the cost estimates with particular attention to the relationship between patient age and cost. The study sample was drawn from an administrative data set of all hospital discharges from five academic medical centers for the 1992 calendar year. Using International Classification of Diseases (ICD-9-CM) primary diagnosis codes, cases were classified into cerebrovascular subgroups: subarachnoid hemorrhage (SAH), intracerebral hemorrhage (ICH), ischemic cerebral infarction (ICI), and transient ischemic attack (TIA). The ICD-9-driven data file was supplemented with billing data containing inpatient charges reported in UB-82 format. Costs were imputed by applying Medicare charge-to-cost ratios and regional wage adjustments to the billing data. We estimated relationships between inpatient costs and a number of demographic and administrative variables. A statistically significant difference was found between cerebrovascular subgroups for both the mean cost per discharge (p<0.01) and the mean cost of an inpatient day (p<0.01). The mean cost per discharge for each subgroup was as follows: SAH, $39,994 (n=218); ICH, $21,535 (n=258); ICI, $9,882 (n=908); TIA, $4,653 (n=303). Likewise, the mean cost per inpatient day was as follows: SAH, $2,215; ICH, $1,396; ICI, $1,036; TIA, $1,117. Length of stay as a measure of resource use was strongly predictive of inpatient cost, explaining 72 to 82% of the variation in cost. Demographic variables (i.e., age, gender, race, insurance status), however, revealed virtually no predictive power, accounting for less than 10% of the variance in each of the four subgroups. There are substantial differences in the patient-level cost of hospital services for stroke-related events. After controlling for the type of cerebrovascular event, basic demographic variables and insurance status (including Medicare) contribute little to the total cost of inpatient care. More important factor include stroke severity, social factors, and clinical practice variations.
