Stroke care delivery before vs after JCAHO stroke center certification

Experiences of family caregivers 3-months after stroke: results of the prospective trans-regional network for stroke intervention with telemedicine registry (TRANSIT-Stroke)

Background

Long-term support of stroke patients living at home is often delivered by family caregivers (FC). We identified characteristics of stroke patients being associated with receiving care by a FC 3-months (3 M) after stroke, assessed positive and negative experiences and individual burden of FC caring for stroke patients and determined factors associated with caregiving experiences and burden of FC 3 M after stroke.

Methods

Data were collected within TRANSIT-Stroke, a regional telemedical stroke-network comprising 12 hospitals in Germany. Patients with stroke/TIA providing informed consent were followed up 3 M after the index event. The postal patient-questionnaire was accompanied by an anonymous questionnaire for FC comprising information on positive and negative experiences of FC as well as on burden of caregiving operationalized by the Caregiver Reaction Assessment and a self-rated burden-scale, respectively. Multivariable logistic and linear regression analyses were performed.

Results

Between 01/2016 and 06/2019, 3532 patients provided baseline and 3 M-follow-up- data and 1044 FC responded to questionnaires regarding positive and negative caregiving experiences and caregiving burden. 74.4% of FC were older than 55 years, 70.1% were women and 67.5% were spouses. Older age, diabetes and lower Barthel-Index in patients were significantly associated with a higher probability of receiving care by a FC at 3 M. Positive experiences of FC comprised the importance (81.5%) and the privilege (70.0%) of caring for their relative; negative experiences of FC included financial difficulties associated with caregiving (20.4%). Median overall self-rated burden was 30 (IQR: 0–50; range 0–100). Older age of stroke patients was associated with a lower caregiver burden, whereas younger age of FC led to higher burden. More than half of the stroke patients in whom a FC questionnaire was completed did self-report that they are not being cared by a FC. This stroke patient group tended to be younger, more often male with less severe stroke and less comorbidities who lived more often with a partner.

Conclusions

The majority of caregivers wanted to care for their relatives but experienced burden at the same time. Elderly patients, patients with a lower Barthel Index at discharge and diabetes are at higher risk of needing care by a family caregiver.

Development of a Joint Commission Disease-Specific Care Certification Program for Parkinson Disease in an Acute Care Hospital

BACKGROUND

Patients with Parkinson disease (PD) admitted to the hospital for any reason are at a higher risk of hospital-related complications. Frequent causes include delays in administering PD medications or use of contraindicated medications. The Joint Commission Disease-Specific Care (DSC) program has been used to establish a systematic approach to the care of specific inpatient populations. Once obtained, this certification demonstrates a commitment to patient care and safety, which is transparent to the public and can improve quality of care.

METHODS

We formalized our efforts to improve the care of hospitalized patients with PD by pursuing Joint Commission DSC. An interprofessional team was assembled to include nurses, therapists, physicians, pharmacists, performance improvement specialists, and data analysts. The team identified quality metrics based on clinical guidelines. In addition, a large educational campaign was undertaken. Application to the Joint Commission for DSC resulted in a successful June 15, 2018 site visit. To our knowledge, this is the first DSC program in PD in an acute care hospital.

CONCLUSION

Using the established platform of DSC certification from the Joint Commission, we developed a program based on relevant metrics that aims to address medication management of patients with PD admitted to the hospital. Our hope is to improve the care of this vulnerable patient population.

Electroencephalography Measures are Useful for Identifying Large Acute Ischemic Stroke in the Emergency Department

BACKGROUND

Early diagnosis of stroke optimizes reperfusion therapies, but behavioral measures have incomplete accuracy. Electroencephalogram (EEG) has high sensitivity for immediately detecting brain ischemia. This pilot study aimed to evaluate feasibility and utility of EEG for identifying patients with a large acute ischemic stroke during Emergency Department (ED) evaluation, as these data might be useful in the prehospital setting.

METHODS

A 3-minute resting EEG was recorded using a dense-array (256-lead) system in patients with suspected acute stroke arriving at the ED of a US Comprehensive Stroke Center.

RESULTS

An EEG was recorded in 24 subjects, 14 with acute cerebral ischemia (including 5 with large acute ischemic stroke) and 10 without acute cerebral ischemia. Median time from stroke onset to EEG was 6.6 hours; and from ED arrival to EEG, 1.9 hours. Delta band power (P = .004) and the alpha/delta frequency band ratio (P = .0006) each significantly distinguished patients with large acute ischemic stroke (n = 5) from all other patients with suspected stroke (n = 19), with the best diagnostic utility coming from contralesional hemisphere signals. Larger infarct volume correlated with higher EEG power in the alpha/delta frequency band ratio within both the ipsilesional (r = -0.64, P = .013) and the contralesional (r = -0.78, P = .001) hemispheres.

CONCLUSIONS

Within hours of stroke onset, EEG measures (1) identify patients with large acute ischemic stroke and (2) correlate with infarct volume. These results suggest that EEG measures of brain function may be useful to improve diagnosis of large acute ischemic stroke in the ED, findings that might be useful to pre-hospital applications.

Stroke unit care in germany: the german stroke registers study group (ADSR)

BACKGROUND

Factors influencing access to stroke unit (SU) care and data on quality of SU care in Germany are scarce. We investigated characteristics of patients directly admitted to a SU as well as patient-related and structural factors influencing adherence to predefined indicators of quality of acute stroke care across hospitals providing SU care.

METHODS

Data were derived from the German Stroke Registers Study Group (ADSR), a voluntary network of 9 regional registers for monitoring quality of acute stroke care in Germany. Multivariable logistic regression analyses were performed to investigate characteristics influencing direct admission to SU. Generalized Linear Mixed Models (GLMM) were used to estimate the influence of structural hospital characteristics (percentage of patients admitted to SU, year of SU-certification, and number of stroke and TIA patients treated per year) on adherence to predefined quality indicators.

RESULTS

In 2012 180,887 patients were treated in 255 hospitals providing certified SU care participating within the ADSR were included in the analysis; of those 82.4% were directly admitted to a SU. Ischemic stroke patients without disturbances of consciousness (p < .0001), an interval onset to admission time ≤3 h (p < .0001), and weekend admission (p < .0001) were more likely to be directly admitted to a SU. A higher proportion of quality indicators within predefined target ranges were achieved in hospitals with a higher proportion of SU admission (p = 0.0002). Quality of stroke care could be maintained even if certification was several years ago.

CONCLUSIONS

Differences in demographical and clinical characteristics regarding the probability of SU admission were observed. The influence of structural characteristics on adherence to evidence-based quality indicators was low.

Development and validation of a score for evaluating comprehensive stroke care capabilities: J-ASPECT Study

Background

Although the Brain Attack Coalition recommended establishing centers of comprehensive care for stroke and cerebrovascular disease patients, a scoring system for such centers was lacking. We created and validated a comprehensive stroke center (CSC) score, adapted to Japanese circumstances.

Methods

Of the selected 1369 certified training institutions in Japan, 749 completed an acute stroke care capabilities survey. Hospital performance was determined using a 25-item score, evaluating 5 subcategories: personnel, diagnostic techniques, specific expertise, infrastructure, and education. Consistency and validity were examined using correlation coefficients and factorial analysis.

Results

The CSC score (median, 14; interquartile range, 11–18) varied according to hospital volume. The five subcategories showed moderate consistency (Cronbach’s α = 0.765). A strong correlation existed between types of available personnel and specific expertise. Using the 2011 Japanese Diagnosis Procedure Combination database for patients hospitalized with stroke, four constructs were identified by factorial analysis (neurovascular surgery and intervention, vascular neurology, diagnostic neuroradiology, and neurocritical care and rehabilitation) that affected in-hospital mortality from ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage. The total CSC score was related to in-hospital mortality from ischemic stroke (odds ratio [OR], 0.973; 95% confidence interval [CI], 0.958–0.989), intracerebral hemorrhage (OR, 0.970; 95% CI, 0.950–0.990), and subarachnoid hemorrhage (OR, 0.951; 95% CI, 0.925–0.977), with varying contributions from the four constructs.

Conclusions

The CSC score is a valid measure for assessing CSC capabilities, based on the availability of neurovascular surgery and intervention, vascular neurology, diagnostic neuroradiology, and critical care and rehabilitation services.

Hospital Disease-Specific Care Certification Programs and Quality of Care: A Narrative Review

BACKGROUND

Disease-specific care certification (DSCC) programs have been developed to improve the quality and performance of programs or services that may be based within or associated with a hospital or other health care organization. A comprehensive summary of evidence for DSCC programs and their reported effect on the quality of care was prepared in a narrative review, the first of its kind on this topic.

METHODS

A systematic search was performed to identify articles that reported about DSCC. Any article that reported DSCC and certifications, published between 2003 and August 2015 (with an update in March 2016), and conducted in the United States was included. Databases searched included PubMed, MEDLINE, and CINAHL.

RESULTS

The articles were reviewed in terms of four topics: early development of DSCC, the journey toward DSCC, the relationship between DSCC and organizing process of care, and the relationship between DSCC and outcomes of care. Fifteen articles noted a positive relationship between DSCC programs and quality of care, only 6 of which reported empirical data. Therefore, a systematic review and meta-analysis were not warranted. Only 3 articles involved use of sophisticated statistical modeling with adequate control variables to investigate the effect of DSCC, which makes it difficult to conclude that the change in hospitals' or patients' outcomes were related to the certification.

CONCLUSIONS

The majority (13) of the articles focused on Joint Commission DSCC, with the remaining assessing Society of Cardiovascular Patient Care "accreditation" (certification). Only two studies, each study using a cross-sectional design, that empirically examined the relationship between DSCC and outcomes of care-mortality of care and readmission. More research studies are needed to evaluate the effectiveness of DSCC programs in improving outcomes of care, particularly patient-centered outcome measures, such as patient satisfaction and self-care.

Emerging temporal trends in tissue plasminogen activator use: Results from the BASIC project

OBJECTIVE

To explore temporal trends in tissue plasminogen activator (tPA) administration for acute ischemic stroke (AIS) in a biethnic community without an academic medical center and variation in trends by age, sex, ethnicity, and stroke severity.

METHODS

Cases of AIS were identified from 7 hospitals in the Brain Attack Surveillance in Corpus Christi (BASIC) project, a population-based surveillance study between January 1, 2000, and June 30, 2012. tPA, demographics, and stroke severity as assessed by the NIH Stroke Scale (NIHSS) were ascertained from medical records. Temporal trends were explored using generalized estimating equations, and adjustment made for age, sex, ethnicity, and NIHSS. Interaction terms were included to test for effect modification.

RESULTS

There were 5,277 AIS cases identified from 4,589 unique individuals. tPA use was steady at 2% and began increasing in 2006, reaching 11% in subsequent years. Stroke severity modified temporal trends (p = 0.003) such that cases in the highest severity quartile (NIHSS > 8) had larger increases in tPA use than those in lower severity quartiles. Although ethnicity did not modify the temporal trend, Mexican Americans (MAs) were less likely to receive tPA than non-Hispanic whites (NHWs) due to emerging ethnic differences in later years.

CONCLUSIONS

Dramatic increases in tPA use were apparent in this community without an academic medical center. Primary stroke center certification likely contributed to this rise. Results suggest that increases in tPA use were greater in higher severity patients compared to lower severity patients, and a gap between MAs and NHWs in tPA administration may be emerging.

Neurothrombectomy trial results: stroke systems, not just devices, make the difference

The overwhelming benefit demonstrated in the four recent randomized trials comparing intra-arterial therapies to medical management alone will have a transformative effect on the emergent management of strokes throughout the world. New generation neurothrombectomy devices were critical to trial success, but not the sole driver of patient outcomes in these trials. Patients in the positive trials were treated at hospitals with complex, efficient, resource-rich, team-based stroke systems in place. To ensure attainment of trial results in actual practice, patients should receive treatment at facilities certified as having the resources, personnel, organization, and continuous quality improvement processes characteristic of trial centers. It is our hope that, through greater education initiatives, robust resource investment, and developing quality-based certification processes, the results demonstrated by these trials may be extrapolated to greater numbers of centers - in turn allowing greater access for patients to high-quality, advanced stroke care.

International multidisciplinary consensus conference on multimodality monitoring: ICU processes of care

There is an increased focus on evaluating processes of care, particularly in the high acuity and cost environment of intensive care. Evaluation of neurocritical-specific care and evidence-based protocol implementation are needed to effectively determine optimal processes of care and effect on patient outcomes. General quality measures to evaluate intensive care unit (ICU) processes of care have been proposed; however, applicability of these measures in neurocritical care populations has not been established. A comprehensive literature search was conducted for English language articles from 1990 to August 2013. A total of 1,061 articles were reviewed, with 145 meeting criteria for inclusion in this review. Care in specialized neurocritical care units or by neurocritical teams can have a positive impact on mortality, length of stay, and in some cases, functional outcome. Similarly, implementation of evidence-based protocol-directed care can enhance outcome in the neurocritical care population. There is significant evidence to support suggested quality indicators for the general ICU population, but limited research regarding specific use in neurocritical care. Quality indices for neurocritical care have been proposed; however, additional research is needed to further validate measures.

Evaluating the impact of accreditation and external peer review

Purpose

– Accreditation and external peer review play important roles in assessing and improving healthcare quality worldwide. Evidence on the impact on the quality of care remains indecisive because of programme features and methodological research challenges. The purpose of this paper is to create a general methodological research framework to design future studies in this field.

Design/methodology/approach

– A literature search on effects of external peer review and accreditation was conducted using PubMed/Medline, Embase and Web of Science. Three researchers independently screened the studies. Only original research papers that studied the impact on the quality of care were included. Studies were evaluated by their objectives and outcomes, study size and analysis entity (hospitals vs patients), theoretical framework, focus of the studied programme, heterogeneity of the study population and presence of a control group.

Findings

– After careful selection 50 articles were included out of an initial 2,025 retrieved references. Analysis showed a wide variation in methodological characteristics. Most studies are performed cross-sectionally and results are not linked to the programme by a theoretical framework.

Originality/value

– Based on the methodological characteristics of previous studies the authors propose a general research framework. This framework is intended to support the design of future research to evaluate the effects of accreditation and external peer review on the quality of care.

Compliance with acute stroke care quality measures in hospitals with and without primary stroke center certification: the North Carolina Stroke Care Collaborative

Background

Organized stroke care is associated with improved outcomes. Data are limited on differences in changes in the quality of acute stroke care at The Joint Commission–certified Primary Stroke Centers (PSCs) versus non‐PSCs over time.

Methods and Results

We compared compliance with the Joint Commission's 10 acute stroke care performance measures and defect‐free care in PSCs and non‐PSCs participating in the Registry of the North Carolina Stroke Care Collaborative from January 2005 through February 2010. We included 29 654 cases presenting at 47 hospitals—10 PSCs, 8 preparing for certification, and 29 non‐PSCs—representing 43% of North Carolina's non–Veterans Affairs, acute care hospitals. Using a non‐PSC referent, odds ratios and 95% CIs were calculated using logistic regression and generalized estimating equations accounting for clustering of cases within hospitals. Time trends were presented graphically using simple linear regression. Performance measure compliance increased for all measures for all 3 groups in 2005–2010, with the exception of discharge on antithrombotics, which remained consistently high. PSCs and hospitals preparing for certification had better compliance with all but 2 performance measures compared with non‐PSCs (each P<0.01). Defect‐free care was delivered most consistently at hospitals preparing for certification (52.8%), followed by PSCs (45.0%) and non‐PSCs (21.9%). Between 2005 and 2010, PSCs and hospitals preparing for certification had a higher average annual percent increase in the provision of defect‐free care (P=0.01 and 0.04, respectively) compared with non‐PSCs.

Conclusions

PSC certification is associated with an overall improvement in the quality of stroke care in North Carolina; however, room for improvement remains.

Telemedicine in stroke care and rehabilitation

Telemedicine allows prompt assessment of acute stroke patients. This new technology has increased the administration of intravenous recombinant tissue plasminogen activator (rtPA) to eligible patients. In addition, telemedicine is being utilized in the rehabilitation of patients with cerebrovascular disease. This article will review the use of telemedicine in patients with acute ischemic stroke and its implementation in telerehabilitation to patients with residual neurologic deficits.

Guidelines for the early management of patients with acute ischemic stroke: a guideline for healthcare professionals from the American Heart Association/American Stroke Association

BACKGROUND AND PURPOSE

The authors present an overview of the current evidence and management recommendations for evaluation and treatment of adults with acute ischemic stroke. The intended audiences are prehospital care providers, physicians, allied health professionals, and hospital administrators responsible for the care of acute ischemic stroke patients within the first 48 hours from stroke onset. These guidelines supersede the prior 2007 guidelines and 2009 updates.

METHODS

Members of the writing committee were appointed by the American Stroke Association Stroke Council's Scientific Statement Oversight Committee, representing various areas of medical expertise. Strict adherence to the American Heart Association conflict of interest policy was maintained throughout the consensus process. Panel members were assigned topics relevant to their areas of expertise, reviewed the stroke literature with emphasis on publications since the prior guidelines, and drafted recommendations in accordance with the American Heart Association Stroke Council's Level of Evidence grading algorithm.

RESULTS

The goal of these guidelines is to limit the morbidity and mortality associated with stroke. The guidelines support the overarching concept of stroke systems of care and detail aspects of stroke care from patient recognition; emergency medical services activation, transport, and triage; through the initial hours in the emergency department and stroke unit. The guideline discusses early stroke evaluation and general medical care, as well as ischemic stroke, specific interventions such as reperfusion strategies, and general physiological optimization for cerebral resuscitation.

CONCLUSIONS

Because many of the recommendations are based on limited data, additional research on treatment of acute ischemic stroke remains urgently needed.

Influence of hematoma location on acute mortality after intracerebral hemorrhage

BACKGROUND AND PURPOSE

This study aimed to identify predictors of acute mortality after intracerebral hemorrhage (ICH), including voxel-wise analysis of hematoma location.

METHODS

In 282 consecutive patients with acute ICH, clinical and radiological predictors of acute mortality were identified. Voxel-based lesion-symptom mapping examined spatial correlates of acute mortality, contrasting results in basal ganglia ICH and lobar ICH.

RESULTS

Acute mortality was 47.9%. In bivariate analyses, one clinical (serum glucose) and two radiological (hematoma volume and intraventricular extension) measures significantly predicted mortality. The relationship was strongest for hematoma volume. Multivariable modeling identified four significant predictors of mortality (ICH volume, intraventricular extension, serum glucose, and serum hemoglobin), although this model only minimally improved the predictive value provided by ICH volume alone. Voxel-wise analysis found that for patients with lobar ICH, brain regions where acute hematoma was significantly associated with higher acute mortality included inferior parietal lobule and posterior insula; for patients with basal ganglia ICH, a large region extending from cortex to brainstem.

CONCLUSIONS

For patients with lobar ICH, acute mortality is related to both hematoma size and location, with findings potentially useful for therapeutic decision making. The current findings also underscore differences between the syndromes of acute deep and lobar ICH.

Changes in Interhospital Transfer Patterns of Acute Ischemic Stroke Patients in the Regional Stroke Care System After Designation of a Cerebrovascular-specified Center

The Ministry of Health and Welfare of Korea recently designated cerebrovascularspecified centers (CSCs) to improve the regional stroke care system for acute ischemic stroke (AIS) patients. This study was performed to evaluate the changes in the flow of AIS patients between hospitals and to describe the role of the Emergency Medical Information Center (EMIC) after the designation of the CSCs. Data for coordination of interhospital transfers by the EMIC were reviewed for 6 months before and after designation of the CSCs. The data included the success or failure rate, the time used for coordination of interhospital transfer, and the changes in the interhospital transfer pattern between transfer-requesting and transfer-accepting hospitals. The total number of requests for interhospital transfer increased from 198 to 244 after designation of the CSCs. The median time used for coordination decreased from 8.0 minutes to 4.0 minutes (p<0.001). The success rate of coordination increased from 88.9% to 96.7% (p<0.001). The proportion of requests by CSCs decreased from 3.5% to 0.4% (p=0.017). However, the proportion of acceptance by non-CSC hospitals increased from 15.9% to 25.8% (p=0.015). With the designation of CSCs, the EMIC could coordinate interhospital transfers more quickly. However, AIS patients are more dispersed to CSC and non-CSC hospitals, which might be because the CSCs still do not have sufficient resources to cover the increasing volume of AIS patients and non-CSC hospitals have changed their policies. Further studies based on patients' outcome are needed to determine the adequate type of interhospital transfer for AIS patients.

Narrative synthesis of health service accreditation literature

AIMS

To systematically identify and synthesise health service accreditation literature.

METHODS

A systematic identification and narrative synthesis of health service accreditation literature published prior to 2012 were conducted. The search identified 122 empirical studies that examined either the processes or impacts of accreditation programmes. Study components were recorded, including: dates of publication; research settings; levels of study evidence and quality using established rating frameworks; and key results. A content analysis was conducted to determine the frequency of key themes and subthemes examined in the literature and identify knowledge-gaps requiring research attention.

RESULTS

The majority of studies (n=67) were published since 2006, occurred in the USA (n=60) and focused on acute care (n=79). Two thematic categories, that is, 'organisational impacts' and 'relationship to quality measures', were addressed 60 or more times in the literature. 'Financial impacts', 'consumer or patient satisfaction' and 'survey and surveyor issues' were each examined fewer than 15 times. The literature is limited in terms of the level of evidence and quality of studies, but highlights potential relationships among accreditation programmes, high quality organisational processes and safe clinical care.

CONCLUSIONS

Due to the limitations of the literature, it is not prudent to make strong claims about the effectiveness of health service accreditation. Nonetheless, several critical issues and knowledge-gaps were identified that may help stimulate and inform discussion among healthcare stakeholders. Ongoing effort is required to build upon the accreditation evidence-base by using high quality experimental study designs to examine the processes, effectiveness and financial value of accreditation programmes and their critical components in different healthcare domains.

The standard of healthcare accreditation standards: a review of empirical research underpinning their development and impact

BACKGROUND

Healthcare accreditation standards are advocated as an important means of improving clinical practice and organisational performance. Standard development agencies have documented methodologies to promote open, transparent, inclusive development processes where standards are developed by members. They assert that their methodologies are effective and efficient at producing standards appropriate for the health industry. However, the evidence to support these claims requires scrutiny. The study's purpose was to examine the empirical research that grounds the development methods and application of healthcare accreditation standards.

METHODS

A multi-method strategy was employed over the period March 2010 to August 2011. Five academic health research databases (Medline, Psych INFO, Embase, Social work abstracts, and CINAHL) were interrogated, the websites of 36 agencies associated with the study topic were investigated, and a snowball search was undertaken. Search criteria included accreditation research studies, in English, addressing standards and their impact. Searching in stage 1 initially selected 9386 abstracts. In stage 2, this selection was refined against the inclusion criteria; empirical studies (n = 2111) were identified and refined to a selection of 140 papers with the exclusion of clinical or biomedical and commentary pieces. These were independently reviewed by two researchers and reduced to 13 articles that met the study criteria.

RESULTS

The 13 articles were analysed according to four categories: overall findings; standards development; implementation issues; and impact of standards. Studies have only occurred in the acute care setting, predominately in 2003 (n = 5) and 2009 (n = 4), and in the United States (n = 8). A multidisciplinary focus (n = 9) and mixed method approach (n = 11) are common characteristics. Three interventional studies were identified, with the remaining 10 studies having research designs to investigate clinical or organisational impacts. No study directly examined standards development or other issues associated with their progression. Only one study noted implementation issues, identifying several enablers and barriers. Standards were reported to improve organisational efficiency and staff circumstances. However, the impact on clinical quality was mixed, with both improvements and a lack of measurable effects recorded.

CONCLUSION

Standards are ubiquitous within healthcare and are generally considered to be an important means by which to improve clinical practice and organisational performance. However, there is a lack of robust empirical evidence examining the development, writing, implementation and impacts of healthcare accreditation standards.

Elements of a stroke center

The past decade has ushered in a refined understanding of--and commitment to--objective evidence-based practice of stroke management. Responding to the need for universal protocol-driven guidelines for stroke care, the Brain Attack Coalition published consensus statements with recommendations for primary stroke centers (Alberts MJ, et al, JAMA 283:3102-3109, 2000) and comprehensive stroke centers (Alberts MJ, et al, Stroke 36:1597-1616, 2005) in 2000 and 2005, respectively. These benchmark publications helped to define a new "standard of care" for stroke patients and laid the groundwork to establish formal certification for stroke centers. Although large randomized controlled trials evaluating the efficacy of these guidelines are currently underway, several recent reports suggest that stroke center certification may improve outcomes in patients with acute ischemic stroke. In this article, the authors briefly discuss the status of stroke center certification and the evolution of stroke systems of care.

Regional Variation in Recommended Treatments for Ischemic Stroke and TIA

Background and Purpose—

Secondary stroke prevention treatments vary in different regions of the US. We determined the degree to which guideline-recommended stroke treatments vary by region for patients treated at hospitals participating in a voluntary national quality improvement program, Get With The Guidelines-Stroke.

Methods—

Receipt of 8 guideline-recommended treatments (intravenous tissue-type plasminogen activator, antihypertensives, antithrombotics, anticoagulants for atrial fibrillation, deep vein thrombosis prophylaxis, lipid-lowering medications at discharge, smoking cessation counseling, weight loss education) and defect-free care were compared in 4 US regions among eligible patients with ischemic stroke and transient ischemic attack; there was adjustment for patient demographics, medical history, and hospital characteristics.

Results—

Among 991 995 admissions (South, 37%; Northeast, 27.6%; Midwest, 19.3%; West, 15.9%). Receipt varied regionally for tissue-type plasminogen activator (58.2%–67.8%), lipid-lowering medications (72.5%–75.7%), antihypertensives (80.1%–83.6%), antithrombotics (95.6%–96.8%), deep vein thrombosis prophylaxis (88.0%–91.4%), weight loss education (49.3%–54.7%), and defect-free care (72.1%–76.5%). In adjusted analyses, patients in the South had lower odds of use of intravenous tissue-type plasminogen activator (OR [95% CI]; 0.82 [0.69–0.97]), antihypertensives (0.82 [0.67–0.99]), and defect-free care (0.83 [0.75–0.92]); but, they were more likely to receive lipid-lowering medications (1.28 [1.05–1.54]) compared with those in the Northeast. Patients in the Midwest had lower odds of intravenous tissue-type plasminogen activator administration (0.82 [0.68–0.99]) and defect-free care (0.81 [0.72–0.92]). Those in the West had lower odds of antihypertensives (0.81 [0.67–0.99]), but had greater odds of receiving lipid-lowering medications (1.26 [1.03–1.53]).

Conclusions—

Despite relatively high rates of adherence to stroke-related therapies in Get With The Guidelines-Stroke hospitals, regional variations exist, with over one quarter of patients receiving suboptimal care. Systematic improvements may lead to better patient outcomes.

Access to Expert Stroke Care with Telemedicine: REACH MUSC

Stroke is a leading cause of death and disability, and recombinant tissue plasminogen activator (rtPA) can significantly reduce the long-term impact of acute ischemic stroke (AIS) if given within 3 h of symptom onset. South Carolina is located in the "stroke belt" and has a high rate of stroke and stroke mortality. Many small rural SC hospitals do not maintain the expertise needed to treat AIS patients with rtPA. MUSC is an academic medical center using REACH MUSC telemedicine to deliver stroke care to 15 hospitals in the state, increasing the likelihood of timely treatment with rtPA. The purpose of this study is to determine the increase in access to rtPA through the use of telemedicine for AIS in the general population and in specific segments of the population based on age, gender, race, ethnicity, education, urban/rural residence, poverty, and stroke mortality. We used a retrospective cross-sectional design examining Census data from 2000 and geographic information systems analysis to identify South Carolina residents that live within 30 or 60 min of a primary stroke center (PSC) or a REACH MUSC site. We include all South Carolina citizens in our analysis and specifically examine the population's age, gender, race, ethnicity, education, urban/rural residence, poverty, and stroke mortality. Our sample includes 4,012,012 South Carolinians. The main measure is access to expert stroke care at a PSC or a REACH MUSC hospital within 30 or 60 min. We find that without REACH MUSC, only 38% of the population has potential access to expert stroke care in SC within 60 min given that most PSCs will maintain expert stroke coverage. REACH MUSC allows 76% of the population to be within 60 min of expert stroke care, and 43% of the population to be within 30 min drive time of expert stroke care. These increases in access are especially significant for groups that have faced disparities in care and high rates of AIS. The use of telemedicine can greatly increase access to care for residents throughout South Carolina.

Neurointerventional procedural volume per hospital in United States: implications for comprehensive stroke center designation

BACKGROUND AND PURPOSE

Availability of neurointerventional procedures is recommended as a necessary component of a comprehensive stroke center by various regulatory guidelines that also emphasize adequate procedural volumes. We studied the volumes of neurointerventional procedures performed in various hospitals across the United States with subsequent comparisons with rates of minimum procedural volumes recommended by various professional bodies or used in clinical trials to ensure adequate operator experience.

METHODS

We reviewed the Nationwide Inpatient Sample database in the United States for the years 2005 to 2008. Using International Classification of Disease-Clinical Modification, 9th revision, and Medicare severity diagnosis-related group codes, we identified among hospitals that admit stroke patients those that met the minimum criteria for overall and individual procedural volumes specified in various guidelines. We then compared the characteristics between the high-volume hospitals that performed at least 100 cervicocerebral angiograms and met ≥1 other procedural criterion (n=79) and low-volume hospitals (n=958).

RESULTS

Proportions of hospitals that met individual procedural volume criteria over the 4-year period according to procedure were: cervicocerebral angiography (7.0%-7.8%); endovascular acute ischemic stroke treatments (0.4%-2.6%); carotid angioplasty/stent placement (3.0%-5.3%); intracranial angioplasty/stent placement (0.3%-1.3%); and aneurysm embolization (1.3%-2.6%). There were significant trends for increasing numbers of all the endovascular procedures except intracranial angioplasty/stent placement over the course of 4 years. The high-volume hospitals were more likely to be urban teaching hospitals (70.9% versus 13.1%; P<0.001), had larger bed size (79.7% versus 26.9%; P<0.001), and had significantly higher rates of hemorrhagic stroke admissions and lower rates of transient ischemic attack admissions. Urban teaching location/status (OR, 8.92; CI, 4.3-18.2; P<0.001) and large bed size (OR, 4.40; CI, 2.0-9.5; P<0.001) remained as independent predictors of a high-volume hospital when adjusted for age, gender, risk factors, and stroke subtype.

CONCLUSIONS

There are very few hospitals in the United States that meet all the neurointerventional procedural volume criteria for all endovascular procedures recommended to ensure adequate operator experience. Our results support the creation of specialized regional centers for ensuring adequate procedural volume within treating hospitals.

Organization of a United States county system for comprehensive acute stroke care

BACKGROUND AND PURPOSE

Organized systems of care have the potential to improve acute stroke care delivery. The current report describes the experience of implementing a county-wide system of spoke-and-hub stroke neurology receiving centers (SNRC) that incorporated several comprehensive stroke center recommendations.

METHODS

Observational study of patients with suspected stroke of <5 hours duration transported by emergency medical system personnel to an SNRC during the first year of this system.

RESULTS

A total of 1360 patients with suspected stroke were evaluated at 9 hub SNRC, of which 553 (40.7%) had a discharge diagnosis of ischemic stroke. Of these 553, intravenous tissue-type plasminogen activator was administered to 110 patients (19.9% of ischemic strokes). Care at the 6 neurointerventional-ready SNRC was a major focus in which 25.1% (99/395) of the patients with ischemic stroke received acute intravenous or intra-arterial reperfusion therapy, and in which provision of such therapies was less common with milder stroke, older age, and Hispanic origin. The door-to-needle time for intravenous tissue-type plasminogen activator met the <60-minute target in only 25% of patients and was 37% longer (P=0.0001) when SNRC were neurointerventional-ready.

CONCLUSIONS

A stroke system that incorporates features of comprehensive stroke centers can be effectively implemented with substantial rates of acute reperfusion therapy administration. Experiences potentially useful to broader implementation of comprehensive stroke centers are considered.

30-day mortality and readmission after hemorrhagic stroke among Medicare beneficiaries in Joint Commission primary stroke center-certified and noncertified hospitals

BACKGROUND AND PURPOSE

Ischemic stroke patients treated at Joint Commission Primary Stroke Center (JC-PSC)-certified hospitals have better outcomes. Data reflecting the impact of JC-PSC status on outcomes after hemorrhagic stroke are limited. We determined whether 30-day mortality and readmission rates after hemorrhagic stroke differed for patients treated at JC-PSC-certified versus noncertified hospitals.

METHODS

The study included all fee-for-service Medicare beneficiaries aged 65 years or older with a primary discharge diagnosis of subarachnoid hemorrhage (SAH) or intracerebral hemorrhage (ICH) in 2006. Covariate-adjusted logistic and Cox proportional hazards regression assessed the effect of care at a JC-PSC-certified hospital on 30-day mortality and readmission.

RESULTS

There were 2305 SAH and 8708 ICH discharges from JC-PSC-certified hospitals and 3892 SAH and 22 564 ICH discharges from noncertified hospitals. Unadjusted in-hospital mortality (SAH: 27.5% versus 33.2%, P<0.0001; ICH: 27.9% versus 29.6%, P=0.003) and 30-day mortality (SAH: 35.1% versus 44.0%, P<0.0001; ICH: 39.8% versus 42.4%, P<0.0001) were lower in JC-PSC hospitals, but 30-day readmission rates were similar (SAH: 17.0% versus 17.0%, P=0.97; ICH: 16.0% versus 15.5%, P=0.29). Risk-adjusted 30-day mortality was 34% lower (odds ratio, 0.66; 95% confidence interval, 0.58-0.76) after SAH and 14% lower (odds ratio, 0.86; 95% confidence interval, 0.80-0.92) after ICH for patients discharged from JC-PSC-certified hospitals. There was no difference in 30-day risk-adjusted readmission rates for SAH or ICH based on JC-PSC status.

CONCLUSIONS

Patients treated at JC-PSC-certified hospitals had lower risk-adjusted mortality rates for both SAH and ICH but similar 30-day readmission rates as compared with noncertified hospitals.

Revised and updated recommendations for the establishment of primary stroke centers: a summary statement from the brain attack coalition

BACKGROUND AND PURPOSE

The formation and certification of Primary Stroke Centers has progressed rapidly since the Brain Attack Coalition's original recommendations in 2000. The purpose of this article is to revise and update our recommendations for Primary Stroke Centers to reflect the latest data and experience.

METHODS

We conducted a literature review using MEDLINE and PubMed from March 2000 to January 2011. The review focused on studies that were relevant for acute stroke diagnosis, treatment, and care. Original references as well as meta-analyses and other care guidelines were also reviewed and included if found to be valid and relevant. Levels of evidence were added to reflect current guideline development practices.

RESULTS

Based on the literature review and experience at Primary Stroke Centers, the importance of some elements has been further strengthened, and several new areas have been added. These include (1) the importance of acute stroke teams; (2) the importance of Stroke Units with telemetry monitoring; (3) performance of brain imaging with MRI and diffusion-weighted sequences; (4) assessment of cerebral vasculature with MR angiography or CT angiography; (5) cardiac imaging; (6) early initiation of rehabilitation therapies; and (7) certification by an independent body, including a site visit and disease performance measures.

CONCLUSIONS

Based on the evidence, several elements of Primary Stroke Centers are particularly important for improving the care of patients with an acute stroke. Additional elements focus on imaging of the brain, the cerebral vasculature, and the heart. These new elements may improve the care and outcomes for patients with stroke cared for at a Primary Stroke Center.

Outcomes after ischemic stroke for hospitals with and without Joint Commission-certified primary stroke centers

BACKGROUND

The Joint Commission (JC) began certifying primary stroke centers (PSCs) in the United States in 2003. We assessed whether 30-day risk-standardized mortality (RSMR) and readmission (RSRR) rates differed between hospitals with and without JC-certified PSCs in 2006.

METHODS

The study cohort included all fee-for-service Medicare beneficiaries ≥65 years old discharged with a primary diagnosis of ischemic stroke (International Classification of Diseases, ninth revision, Clinical Modification 433, 434, 436) in 2006. Hierarchical linear regression models calculated hospital-level RSMRs and RSRRs, adjusting for patient demographics, comorbid conditions, and hospital referral region. Hospitals were categorized as being higher than, no different from, or lower than the national average.

RESULTS

There were 310,381 ischemic stroke discharges from 315 JC-certified PSC and 4,231 noncertified hospitals. Mean overall 30-day RSMR and RSRR were 10.9% ± 1.7% and 12.5% ± 1.4%, respectively. The RSMRs of hospitals with JC-certified PSCs were lower than in noncertified hospitals (10.7% ± 1.7% vs 11.0% ± 1.7%), but the RSRRs were comparable (12.5% ± 1.3% vs 12.4% ± 1.7%). Almost half of JC-certified PSC hospitals had RSMRs lower than the national average compared with 19% of noncertified hospitals, but 13% of JC-certified PSC hospitals had lower RSRRs vs 15% of noncertified hospitals.

CONCLUSIONS

Hospitals with JC-certified PSCs had lower RSMRs compared with noncertified hospitals in 2006; however, differences were small. Readmission rates were similar between the 2 groups. PSC certification generally identified better-performing hospitals for mortality outcomes, but some hospitals with certified PSCs may have high RSMRs and RSRRs whereas some hospitals without PSCs have low rates. Unmeasured factors may contribute to this heterogeneity.

Outcomes before and after initiation of an acute aortic treatment center

BACKGROUND

Acute aortic syndromes remain life-threatening. Time is of the essence, as mortality rises with increasing time after the acute episode. The aim of this report is to show changes in practice and outcomes after the establishment of an acute aortic treatment center (AATC) to expedite the care of acute aortic syndromes in a major metropolitan area with the belief that "door to intervention time under 90 minutes" reduces mortality and morbidity from acute aortic disease.

METHODS

A database of patients admitted with acute aortic disease (Type A and B aortic dissections, acute thoraco-abdominal aortic aneurysms, acute and ruptured abdominal aortic aneurysms) for 1 year prior to initiation (2007) and 1 year after initiation of the pathway (AATC) in 2008 was developed. Comorbidities were scored according to Society of Vascular Surgery criteria. Anatomic and functional outcomes were determined and categorized by Society of Vascular Surgery reporting criteria. Multivariate analysis was performed for categorical outcomes and Cox proportional hazard analyses for time-dependent outcomes.

RESULTS

Six hundred twenty-one patients reported with aortic disease to the cardiovascular services; 306 patients were considered to have acute disease. When compared with the year before the AATC was instituted, there was a 30% increase in the total number of admissions and a 25% increase in acute pathology after setting up the AATC (P = .02). There was a two-fold increase in thoracic aortic dissections admitted to the service. Initiation of the treatment pathway resulted in a highly significant 64% reduction in time to definitive therapy (526 ± 557 vs 187 ± 258 minutes, mean ± SD pre-AATC vs AATC; P = .0001). Comorbidity scores were equivalent between the two cohorts. Despite the increase in acuity, mortality (4% vs 6%) and morbidity (41% vs 45%) rates were unchanged, and there was a significant decrease in intensive care unit length of stay (5 vs 4 days, pre-AATC cohort vs the AATC cohort), but total hospital length of stay (11 vs 10 days) was unchanged. There was no correlation between deaths within 30 days and length of stay in the intensive care unit.

CONCLUSION

Establishment of a multidisciplinary AATC pathway was associated with a 30% increase in volume, 64% reduction in time to definitive treatment, improved throughput with reduced intensive care unit time, and maintained clinical efficacy despite an increase in acute admissions. These results suggest the concept be further evaluated.

Association between stroke center hospitalization for acute ischemic stroke and mortality

CONTEXT

Although stroke centers are widely accepted and supported, little is known about their effect on patient outcomes.

OBJECTIVE

To examine the association between admission to stroke centers for acute ischemic stroke and mortality.

DESIGN, SETTING, AND PARTICIPANTS

Observational study using data from the New York Statewide Planning and Research Cooperative System. We compared mortality for patients admitted with acute ischemic stroke (n = 30,947) between 2005 and 2006 at designated stroke centers and nondesignated hospitals using differential distance to hospitals as an instrumental variable to adjust for potential prehospital selection bias. Patients were followed up for mortality for 1 year after the index hospitalization through 2007. To assess whether our findings were specific to stroke, we also compared mortality for patients admitted with gastrointestinal hemorrhage (n = 39,409) or acute myocardial infarction (n = 40,024) at designated stroke centers and nondesignated hospitals.

MAIN OUTCOME MEASURE

Thirty-day all-cause mortality.

RESULTS

Among 30,947 patients with acute ischemic stroke, 15,297 (49.4%) were admitted to designated stroke centers. Using the instrumental variable analysis, admission to designated stroke centers was associated with lower 30-day all-cause mortality (10.1% vs 12.5%; adjusted mortality difference, -2.5%; 95% confidence interval [CI], -3.6% to -1.4%; P < .001) and greater use of thrombolytic therapy (4.8% vs 1.7%; adjusted difference, 2.2%; 95% CI, 1.6% to 2.8%; P < .001). Differences in mortality also were observed at 1-day, 7-day, and 1-year follow-up. The outcome differences were specific for stroke, as stroke centers and nondesignated hospitals had similar 30-day all-cause mortality rates among those with gastrointestinal hemorrhage (5.0% vs 5.8%; adjusted mortality difference, +0.3%; 95% CI, -0.5% to 1.0%; P = .50) or acute myocardial infarction (10.5% vs 12.7%; adjusted mortality difference, +0.1%; 95% CI, -0.9% to 1.1%; P = .83).

CONCLUSION

Among patients with acute ischemic stroke, admission to a designated stroke center was associated with modestly lower mortality and more frequent use of thrombolytic therapy.

The future of neurology

For the past 200 years, neurology has been deeply rooted in the history and neurologic examination, but 21st century advances in neurosurgery, endovascular techniques, and neuropathology, and an explosion in basic neuroscience research and neuroimaging have added exciting new dimensions to the field. Neurology residency training programs face intense governmental regulatory changes and economic pressures, making it difficult to predict the number of neurology residents being trained for the future. The future job outlook for neurologists in the United States, based on recent survey and trends, suggests an increased demand because of the prevalence of neurologic diseases within the aging population, particularly in underserved urban and rural areas. Telemedicine and "teleconsultation" offer a potential solution to bringing virtual subspecialists to underserved areas. The future for neurology and neuroscience research in the United States remains a high priority according to the National Institute of Neurologic Diseases and Stroke, but this may be affected in the long run by budgetary constraints and a growing deficit.

Stroke patient outcomes in US hospitals before the start of the Joint Commission Primary Stroke Center certification program

BACKGROUND AND PURPOSE

The Joint Commission (JC) began certifying Primary Stroke Centers in November 2003. Cross-sectional studies assessing the impact of certification could be biased if these centers had better outcomes before the start of the program. We determined whether hospitals certified within the first years of the JC program had better outcomes than noncertified hospitals before the start of the certification program.

METHODS

The study sample included Medicare fee-for-service beneficiaries >or=65 years of age discharged with ischemic stroke in 2002 from 5070 hospitals, 317 of which were JC-certified by June 2007. Hierarchical logistic regression and Cox proportional hazards models were used to compare in-hospital mortality, 30-day mortality, and 30-day readmission for patients treated at future JC-certified versus noncertified hospitals.

RESULTS

Among 366 551 patients, 18% (66 300) were treated at hospitals with centers that were JC-certified within the first few years of the program. These patients were younger, more likely to be white and male, and had fewer comorbidities and hospitalizations within the prior year. Unadjusted in-hospital mortality (4.7% versus 5.5%), 30-day mortality (9.8% versus 11.3%), and readmissions (13.8% versus 14.6%) were lower in the future JC-certified hospitals (all P<0.001). These differences remained after risk adjustment (in-hospital mortality: OR, 0.93; 95% CI, 0.90 to 0.96; 30-day mortality: OR, 0.92; 95% CI, 0.87 to 0.96; 30-day readmission: hazard ratio, 0.97; 95% CI, 0.95 to 0.99).

CONCLUSIONS

JC Primary Stroke Center-certified hospitals had better outcomes than noncertified hospitals even before the program began. Cross-sectional studies assessing the effects of stroke center certification need to account for these pre-existing differences.

Critical care transport of patients who have acute neurological emergencies

This article reviews the special questions and issues in critical care transport related specifically to the care of patients who have neurologic emergencies. It first considers potential indications for transport and reviews attempts to create a hierarchical stroke center system akin to that developed for trauma care. It then discusses therapeutic concerns relating to the transport environment and the use of specific interventions, including the effects of end-tidal CO(2) monitoring on intracranial pressure, patient outcomes after traumatic brain injury, and opportunities to initiate therapeutic hypothermia in comatose survivors of cardiac arrest during transport. Finally, the cost of critical care transport of patients who have neurologic emergencies is considered.

Escalating Levels of Access to In-Hospital Care and Stroke Mortality

Background and Purpose— Organized stroke care is an integrated approach to managing stroke to improve stroke outcomes by ensuring that optimal treatment is offered. However, limited information is available comparing different levels of organized care. Our aim was to determine whether escalating levels of organized care can improve stroke outcomes.

Methods— Cohort study including patients with acute ischemic stroke between July 2003 and March 2005 in the Registry of the Canadian Stroke Network (RCSN). The RCSN is the largest clinical database of patients with acute stroke patients seen at selected acute care hospitals in Canada. As stroke unit admission does not automatically imply receipt of comprehensive care, we created the organized care index to represent different levels of access to organized care ranging from 0 to 3 as determined by the presence of occupational therapy/physiotherapy, stroke team assessment, and admission to a stroke unit. The primary end point was early stroke mortality. Secondary end points include 30-day and 1-year mortality.

Results— Overall, 3631 ischemic stroke patients were admitted to 11 hospitals. Seven day stroke mortality was 6.9% (249/3631), 30-day stroke mortality was 12.6% (457/3631), and 1-year stroke mortality was 23.6% (856/3631). Risk-adjusted 7-day mortality was 2.0%, 3.2%, 7.8%, and 22.5% for organized care index of 3, 2, 1, and 0. Higher level of care was associated with lower adjusted mortality (for organized care index 3, OR 0.03, 95% CI 0.02 to 0.07 for 7-day mortality; OR 0.09, 95% CI 0.05 to 0.17 for 30-day mortality; and OR 0.40, 95% CI 0.25 to 0.64 for 1-year mortality).

Conclusions— Higher level of access to care was associated with lower stroke mortality rates. Establishing a well-organized and multidisciplinary system of stroke care will help improve the quality of service delivered and reduce the burden of stroke.

Stroke center designation can be achieved by small hospitals: the Massachusetts experience

In January 2005, the Massachusetts Department of Public Health announced the designation of approved hospitals as Primary Stroke Services (PSS), based on verifiable demonstration of care pathways for acute ischemic stroke. We investigated the effect of hospital characteristics on participation in the PSS program.In 2003, the Massachusetts Department of Public Health surveyed 72 Massachusetts hospitals on their readiness for PSS designation. Survey results and PSS participation rates were compared among hospitals categorized by bed size (<150 vs. > or =150 beds), rural location, and major teaching hospital status. In answer to 2003 survey questions, smaller hospitals (n = 35) were less likely than larger hospitals to have acute stroke teams (P = 0.01), 24-hour rapid computed tomography scanning and interpretation (P = 0.0006), 24-hour neurosurgery coverage (P = 0.001), and a stroke registry (P = 0.007). Smaller hospitals were less likely to be interested in PSS application in 2003 (P = 0.008), and less likely to be designated PSS when ambulance rerouting to PSS hospitals began in July 2005 (P < 0.0001). Despite this, by December 2005 the majority of Massachusetts hospitals (66/71, 92%) had achieved PSS designation. Smaller hospitals were more likely to use telemedicine to access acute stroke teams (P = 0.003).Many smaller hospitals are able to acquire the resources needed for provision of acute stroke care, despite initial limitations. Innovative strategies, such as telemedicine consultation and transfer agreements, may successfully allow smaller hospitals to satisfy Brain Attack Coalition criteria for primary stroke centers.

Regionalization of care for ST-segment elevation myocardial infarction: is it too soon?

Interest in regionalization of the care of acute ST-segment elevation myocardial infarction (STEMI) has gained momentum recently. Optimal treatment of STEMI involves balancing time to treatment and reperfusion options. Primary percutaneous coronary intervention, when performed in a timely fashion, has been shown to be more effective than fibrinolysis. However, numerous practical barriers prevent many STEMI patients from receiving primary percutaneous coronary intervention. In an effort to increase beneficial primary percutaneous coronary intervention administration to STEMI patients, health care leaders have proposed regionalized STEMI care networks with advanced emergency medical services (EMS) involvement. Constructing regionalized STEMI networks presents a policy challenge because this shift in STEMI care would require changes in current EMS and emergency medicine practices. Therefore, we present various perspectives and issues that decisionmakers and system organizers must address properly before deciding whether to adopt this new model of care. Reorganizing STEMI care in a manner analogous to how trauma and stroke care are currently triaged and treated appeals intuitively; however, given the absence of evidence that STEMI regionalization actually improves patient outcomes and is cost-effective, more research is needed to determine whether STEMI regionalization is an efficient model for providing evidence-based care. The concept of STEMI regionalization represents an effort to inform policy according to evidence-based medicine, but real-world quality, geospatial, financial, cost, business, resource, and practice barriers present obstacles to implementing this concept efficiently and effectively.

Neurohospitalists: an emerging model for inpatient neurological care

Over the past decade, the hospitalist model has become a dominant system for the delivery of general adult and pediatric inpatient care. Similar forces, including national mandates to improve safety and quality and intense pressure to safely reduce length of hospital stays, that led to the remarkable growth of hospitalist medicine are now exerting pressure on neurologists. A neurohospitalist model, in which inpatient neurology specialists deliver high-quality and efficient care to neurology patients, is emerging to meet these challenges. Benefits of this system may include more frequent, timely neurology consultations in the hospital and emergency department, as well as improved quality of inpatient neurological education for residents and medical students. Challenges will involve defining the relationship of neurohospitalists with primary stroke centers, the economic feasibility of such neurohospitalist systems, and how to train members of this new field. A neurohospitalist model of care is an emerging idea in neurology that would overcome many regulatory, educational, and economic challenges facing neurologists; further research is needed to gauge the effects of this innovative approach.
