Critical Care Management of Patients After Cardiac Arrest: A Scientific Statement from the American Heart Association and Neurocritical Care Society

The critical care management of patients after cardiac arrest is burdened by a lack of high-quality clinical studies and the resultant lack of high-certainty evidence. This results in limited practice guideline recommendations, which may lead to uncertainty and variability in management. Critical care management is crucial in patients after cardiac arrest and affects outcome. Although guidelines address some relevant topics (including temperature control and neurological prognostication of comatose survivors, 2 topics for which there are more robust clinical studies), many important subject areas have limited or nonexistent clinical studies, leading to the absence of guidelines or low-certainty evidence. The American Heart Association Emergency Cardiovascular Care Committee and the Neurocritical Care Society collaborated to address this gap by organizing an expert consensus panel and conference. Twenty-four experienced practitioners (including physicians, nurses, pharmacists, and a respiratory therapist) from multiple medical specialties, levels, institutions, and countries made up the panel. Topics were identified and prioritized by the panel and arranged by organ system to facilitate discussion, debate, and consensus building. Statements related to postarrest management were generated, and 80% agreement was required to approve a statement. Voting was anonymous and web based. Topics addressed include neurological, cardiac, pulmonary, hematological, infectious, gastrointestinal, endocrine, and general critical care management. Areas of uncertainty, areas for which no consensus was reached, and future research directions are also included. Until high-quality studies that inform practice guidelines in these areas are available, the expert panel consensus statements that are provided can advise clinicians on the critical care management of patients after cardiac arrest.

Hemodynamic Management in the Prevention and Treatment of Delayed Cerebral Ischemia After Aneurysmal Subarachnoid Hemorrhage

One of the most serious complications after subarachnoid hemorrhage (SAH) is delayed cerebral ischemia, the cause of which is multifactorial. Delayed cerebral ischemia considerably worsens neurological outcome and increases the risk of death. The targets of hemodynamic management of SAH have widely changed over the past 30 years. Hypovolemia and hypotension were favored prior to the era of early aneurysmal surgery but were subsequently replaced by the use of hypervolemia and hypertension. More recently, the concept of goal-directed therapy targeting euvolemia, with or without hypertension, is gaining preference. Despite the evolving concepts and the vast literature, fundamental questions related to hemodynamic optimization and its effects on cerebral perfusion and patient outcomes remain unanswered. In this review, we explain the rationale underlying the approaches to hemodynamic management and provide guidance on contemporary strategies related to fluid administration and blood pressure and cardiac output manipulation in the management of SAH.

Guidelines for the Neurocritical Care Management of Aneurysmal Subarachnoid Hemorrhage

BACKGROUND

The neurointensive care management of patients with aneurysmal subarachnoid hemorrhage (aSAH) is one of the most critical components contributing to short-term and long-term patient outcomes. Previous recommendations for the medical management of aSAH comprehensively summarized the evidence based on consensus conference held in 2011. In this report, we provide updated recommendations based on appraisal of the literature using the Grading of Recommendations Assessment, Development, and Evaluation methodology.

METHODS

The Population/Intervention/Comparator/Outcome (PICO) questions relevant to the medical management of aSAH were prioritized by consensus from the panel members. The panel used a custom-designed survey instrument to prioritize clinically relevant outcomes specific to each PICO question. To be included, the study design qualifying criteria were as follows: prospective randomized controlled trials (RCTs), prospective or retrospective observational studies, case-control studies, case series with a sample larger than 20 patients, meta-analyses, restricted to human study participants. Panel members first screened titles and abstracts, and subsequently full text review of selected reports. Data were abstracted in duplicate from reports meeting inclusion criteria. Panelists used the Grading of Recommendations Assessment, Development, and Evaluation Risk of Bias tool for assessment of RCTs and the "Risk of Bias In Nonrandomized Studies - of Interventions" tool for assessment of observational studies. The summary of the evidence for each PICO was presented to the full panel, and then the panel voted on the recommendations.

RESULTS

The initial search retrieved 15,107 unique publications, and 74 were included for data abstraction. Several RCTs were conducted to test pharmacological interventions, and we found that the quality of evidence for nonpharmacological questions was consistently poor. Five PICO questions were supported by strong recommendations, one PICO question was supported by conditional recommendations, and six PICO questions did not have sufficient evidence to provide a recommendation.

CONCLUSIONS

These guidelines provide recommendations for or against interventions proven to be effective, ineffective, or harmful in the medical management of patients with aSAH based on a rigorous review of the available literature. They also serve to highlight gaps in knowledge that should guide future research priorities. Despite improvements in the outcomes of patients with aSAH over time, many important clinical questions remain unanswered.

Impact of COVID-19 on neurocritical care delivery and outcomes in patients with severe acute brain injury - Assessing the initial response in the first US epicenter

To investigate the pandemic’s impact on critically ill patients with neurological emergencies, we compared care metrics and outcomes of patients with severe acute brain injury (SABI) before and during the initial COVID-19 surge at our institution. We included adult patients with SABI during two separate three-month time periods: 'pre-COVID vs COVID'. We further stratified the COVID cohort to characterize outcomes in patients requiring COVID-19 precautions (Patient Under Investigation, ‘PUI’). The primary endpoint was in-hospital mortality; secondary endpoints included length of stay (LOS), diagnostic studies performed, time to emergent decompressive craniectomies (DCHC), ventilator management, and end-of-life care. We included 394 patients and found the overall number of admissions for SABI declined by 29 % during COVID (pre-COVID n = 231 vs COVID, n = 163). Our primary outcome of mortality and most secondary outcomes were similar between study periods. There were more frequent extubation attempts (72.1 % vs 76 %) and the mean time to extubation was shorter during COVID (55.5 h vs 38.2 h). The ICU LOS (6.10 days vs 4.69 days) and hospital LOS (15.32 days vs 11.74 days) was shorter during COVID. More PUIs died than non-PUIs (51.7 % vs 11.2 %), but when adjusted for markers of illness severity, this was not significant. We demonstrate the ability to maintain a consistent care delivery for patients with SABI during the pandemic at our institution. PUIs represent a population with higher illness severity at risk for delays in care. Multicenter, longitudinal studies are needed to explore the impact of the pandemic on patients with acute neurological emergencies.

Proceedings of the First Curing Coma Campaign NIH Symposium: Challenging the Future of Research for Coma and Disorders of Consciousness

Coma and disorders of consciousness (DoC) are highly prevalent and constitute a burden for patients, families, and society worldwide. As part of the Curing Coma Campaign, the Neurocritical Care Society partnered with the National Institutes of Health to organize a symposium bringing together experts from all over the world to develop research targets for DoC. The conference was structured along six domains: (1) defining endotype/phenotypes, (2) biomarkers, (3) proof-of-concept clinical trials, (4) neuroprognostication, (5) long-term recovery, and (6) large datasets. This proceedings paper presents actionable research targets based on the presentations and discussions that occurred at the conference. We summarize the background, main research gaps, overall goals, the panel discussion of the approach, limitations and challenges, and deliverables that were identified.

The Neurocritical Care Society Gender Parity Analysis in Grants and Recognition Awards

BACKGROUND

Several recent studies across the field of medicine have indicated gender disparity in the reception of prestigious awards and research grants, placing women in medicine at a distinct disadvantage. Gender disparity has been observed in neurology, critical care medicine and within various professional societies. In this study, we have examined the longitudinal trends of gender parity in awards and grants within the Neurocritical Care Society (NCS).

METHODS

A retrospective analysis was conducted of all available data longitudinally from 2004, when NCS first granted awards through 2019. We used self-identified gender in the membership roster to record gender for each individual. For individuals without recorded gender, we used a previously validated double verification method using a systematic web-based search. We collected data on six awards distributed by the NCS and divided these awards into two main categories: (1) scientific category: (a) Christine Wijman Young Investigator Award; (b) Best Scientific Abstract Award; (c) Fellowship Grant; (d) INCLINE Grant; and (2) non-scientific category: (a) Travel Grant; and (b) Presidential Citation. Available data were analyzed to evaluate longitudinal trends in awards using descriptive statistics and simple or multiple linear regression analyses, as appropriate.

RESULTS

A total of 445 awards were granted between the years 2004 and 2019. Thirty-six awards were in the scientific category, while 409 awards were in the non-scientific category. Only 8% of women received NCS awards in the scientific awards category, whereas 44% of women received an award in the non-scientific category. Most notable in the scientific category are the Best Scientific Abstract Award and the Fellowship Grant, in which no woman has ever received an award to date, compared to 18 men between both awards. In contrast, women are well represented in the non-scientific awards category with an average of 5% increase per year in the number of women awardees.

CONCLUSIONS

Our data reveal gender disparity, mainly for scientific or research awards. Prompt evaluation of the cause and further actions to address gender disparity in NCS grants and recognition awards is needed to establish gender equity in this area.

Tailoring a Comprehensive Bundled Intervention for ED Fall Prevention

INTRODUCTION

Falls in the emergency department pose an important challenge for patient safety. Multifactorial fall prevention bundles have been associated with a reduction in patient falls in the inpatient setting. The purpose of this project was to tailor and implement a comprehensive fall prevention bundle in our emergency department.

METHODS

Fall bundle components for this intervention were selected on the basis of a review of fall prevention research and included fall risk assessment, safe ambulation, safe toileting, staff communication, early warning, and patient education. The fall risk assessment was tailored to the emergency department through an appraisal of select inpatient fall risk assessments, literature search for ED-specific fall risk factors, and a site-specific chart review, after which pertinent fall risk factors were integrated into a modified screening. Fall prevention materials that were both practical and applicable to the emergency department and facilitated patient safety along each bundle domain were selected for implementation at our site.

RESULTS

The tailored fall prevention bundle was championed by the interdisciplinary ED Fall Prevention Team and implemented over the course of 5 months in 1 emergency department. Education on fall prevention equipment was delivered in a peer-to-peer format, and an online module was designed to guide staff through the new fall risk assessment. The fall prevention bundle was adopted into clinical practice after staff education was completed, and the fall risk screening was merged into the electronic medical record.

DISCUSSION

ED fall prevention requires a comprehensive bundled approach, which includes a fall risk screening and multifactorial interventions that are tailored to the ED setting. Successful implementation relies on the involvement of front-line staff from the design through the delivery of the bundled fall prevention measures. Continued inquiry and innovation in ED fall prevention will help provide a safer health care environment and improve patient outcomes.

A Longitudinal Study of Gender Parity Trends of General Membership and Leadership in the Neurocritical Care Society between 2002 and 2019

BACKGROUND

Several studies in critical care and neurology demonstrate women under-representation in professional societies; representation trends within the Neurocritical Care Society (NCS) are unknown. We examined longitudinal gender parity trends in membership and leadership within NCS.

METHODS

A retrospective study of NCS membership and leadership rosters was conducted. To determine gender, self-reported binary gender was extracted. For individuals without recorded gender, a systematic Web-based search to identify usage of gender-specific pronouns in publicly available biographies was performed. According to previously published methods, available photographs were utilized to record presumed gender identification in the absence of available pronoun descriptors. We analyzed available data longitudinally from 2002 to 2019 and performed descriptive statistical and linear regression analyses.

RESULTS

In overall membership, the proportion of women members demonstrated an average 11% increase between 2005 and 2018 (95% confidence interval (CI) - 8.1 to 30.1, p = 0.08). The proportion of women Board of Directors (BOD) members increased significantly over time to 50% in 2019. There was an increase in women Officers from 0% in the first 3 years (2002-2004) to 40% in 2019, with two women Presidents out of 17 from 2002 to 2019. For available Executive Committee rosters, there was a statistically significant nearly 3% increase per year (95% CI 1.5-4; p = 0.0007) in the proportion of women members. Rosters for Committee members and chairpersons were also incomplete, but in an analysis of the available data, there was a statistically significant increase of 5% per year analyzed (95% CI 0.5-9.7; p = 0.04) in the proportion of women Committee members. We also found a statistically significant 4.3% increase per year analyzed (95% CI 2.4-6.1; p = 0.003) in the proportion of women Committee chairpersons.

CONCLUSIONS

This is the first study of longitudinal gender parity trends within neurocritical care. We report that from 2002 to 2019, the NCS has undergone a significant increase in women representation in general membership, committee membership, and leadership positions.

Preserving stroke care during the COVID-19 pandemic: Potential issues and solutions

The coronavirus 2019 (COVID-19) pandemic requires drastic changes in allocation of resources, which can affect the delivery of stroke care, and many providers are seeking guidance. As caregivers, we are guided by 3 distinct principles that will occasionally conflict during the pandemic: (1) we must ensure the best care for those stricken with COVID-19, (2) we must provide excellent care and advocacy for patients with cerebrovascular disease and their families, and (3) we must advocate for the safety of health care personnel managing patients with stroke, with particular attention to those most vulnerable, including trainees. This descriptive review by a diverse group of experts in stroke care aims to provide advice by specifically addressing the potential impact of this pandemic on (1) the quality of the stroke care delivered, (2) ethical considerations in stroke care, (3) safety and logistic issues for providers of patients with stroke, and (4) stroke research. Our recommendations on these issues represent our best opinions given the available information, but are subject to revision as the situation related to the COVID-19 pandemic continues to evolve. We expect that ongoing emergent research will offer additional insights that will provide evidence that could prompt the modification or removal of some of these recommendations.

Comprehensive Stroke Center Certification Series: Setting the Vision

The road to Comprehensive Stroke Center (CSC) certification is challenging and requires full integration of neurological, neurosurgical, neurointerventional, and neurocritical care and rehabilitation services across the entire continuum of care. To successfully achieve this level of certification, centers must coordinate significant resources and services into an organized program. This paper is the first in a three-part series outlining common pitfalls facing many organizations during their journey to initial CSC certification and re-certification and offers a roadmap and pearls for success on this journey. Setting the vision for certification is a key first step in the certification process. This includes fully understanding the certification standards, requirements, and supporting documents. Program leadership must then conduct a thorough gap analysis and build a business plan to support the program as it transitions to a CSC. These key steps should inform the timeline for certification application.

Clinical Performance Measures for Neurocritical Care: A Statement for Healthcare Professionals from the Neurocritical Care Society

BACKGROUND

Performance measures are tools to measure the quality of clinical care. To date, there is no organized set of performance measures for neurocritical care.

METHODS

The Neurocritical Care Society convened a multidisciplinary writing committee to develop performance measures relevant to neurocritical care delivery in the inpatient setting. A formal methodology was used that included systematic review of the medical literature for 13 major neurocritical care conditions, extraction of high-level recommendations from clinical practice guidelines, and development of a measurement specification form.

RESULTS

A total of 50,257 citations were reviewed of which 150 contained strong recommendations deemed suitable for consideration as neurocritical care performance measures. Twenty-one measures were developed across nine different conditions and two neurocritical care processes of care.

CONCLUSIONS

This is the first organized Neurocritical Care Performance Measure Set. Next steps should focus on field testing to refine measure criteria and assess implementation.

Abstract WP317: Reducing Hospital-acquired Pneumonia Rate in Stroke Patients

Objective: To reduce the hospital-acquired pneumonia rate in stroke patients.

Background: The hospital-acquired pneumonia rate for stroke patients at our institution was 6.2% in 2014. This is the 39th percentile for the Joint Commission Comprehensive Stroke Centers in the University HealthSystem Consortium. Our goal was to achieve top decile performance by reducing our hospital-acquired pneumonia rate for stroke patients to 3.0%.

Methods: A multidisciplinary team was assembled with representation from administration, coding, nursing, resident physicians, and attending physicians from stroke, neurocritical care and infectious disease. The team analyzed benchmarking data and decided to use chart review to validate the data. The team decided to use the CDC’s definition and clinical criteria for hospital-acquired pneumonia. Further chart review was performed to find information on swallow evaluations, incentive spirometer use, oral care, and head of bed elevation. A coding manager reviewed the documentation and the coding decision for each patient. After results were presented, the team decided on a course of action.

Results: Review of stroke patients with hospital-acquired pneumonia showed 44% of the patients coded with pneumonia did not meet the clinical definition on physician review. When reviewed by a coding manager, all coding was found to be correct based on the documentation in the chart. To solve this documentation problem, attending physicians discharging stroke patients were informed of these results about unclear pneumonia documentation and were asked to clarify documentation if the diagnosis was not appropriate. After this change, the hospital acquired pneumonia rate in stroke patients fell from 6.2% prior to the changes from April 2014 to March 2015 to 1.9% after the changes were implemented from April to June 2015.

Conclusion: Our facility was able to reduce the rate of hospital-acquired pneumonia in stroke patients from 6.2% to 1.2% through a multidisciplinary approach to achieve more accurate documentation and coding. The widespread over-documentation showed it is clinically difficult to make a diagnosis of pneumonia in this population. Therefore, the rate of hospital-acquired pneumonia is not a valid measure of quality of care.

Bovine hepatic differential gene expression in response to perennial ryegrass staggers

>‘Perennial ryegrass staggers’ is a neurological condition characterised by muscular tremors and ataxia in livestock that ingest the indole diterpene lolitrem B from endophyte-infected perennial ryegrass. While the neurotoxic mechanism of action of ryegrass staggers has been defined, little is known about metabolic and other molecular processes that lolitrem B may affect in livestock. The objective of this study was to characterise differential gene expression in the liver of animals fed lolitrem B-containing feed over an extended period of time. Eighteen steers were fed one of three rations (n=6/group) containing lolitrem B (247, 1,554 or 2,256 μg/kg (dry matter basis)) over 64 days in a double-blind study. Microarray and confirmatory qPCR were performed to evaluate the hepatic gene expression profile from biopsies taken on days 0 and 64. Widespread perturbation of gene expression was observed in all groups receiving lolitrem B, with a total of 152 differential genes identified (false discovery rate ≤0.05). This suggests that chronic exposure to lolitrem B, even at levels below the current threshold of toxicity (2,000 μg/kg lolitrem B), can perturb many genes, biological processes and pathways. Gene ontology and Kyoto Encyclopedia of Genes and Genomes pathway analyses indicated that many of these genes were categorised under lipid/steroid biosynthesis/metabolism and oxidation-reduction. Specifically, genes involved in the biosynthesis pathway of ceramide, a sphingolipid molecule (ACSS2, LASS6 and SCD) and changes in neurosignaling through alteration of nitric oxide synthase activity (ARG1 and GPX4) were up-regulated. Future work should focus on the overall balance between ceramide and its metabolites and antioxidants/oxidants in a variety of body matrices in animals with perennial ryegrass staggers, to determine how these compounds contribute to the overall etiology of this disease.

Abstract 159: Acute Ischemic Stroke Quality Indicators: Implementation of Evidence-Based Practice to Improve Compliance

Background and Purpose: Stroke is the leading cause of adult disability in the United States. Compliance with the stroke quality indicators reinforces that a stroke center is adhering to the evidence based standards of care in acute stroke patients. Hardwiring a process in the delivery of care during hospitalization will ensure improved compliance of these quality indicators.

Methods: A core multidisciplinary team was formed that included neurointensivists, neurologist, neurointerventional radiologist, pharmacist, emergency room and neuro intensive care staff along with neuroscience administration staff. Directors of the various services impacted by the stroke patients were invited on an ad hoc basis. Retrospective chart reviews were performed to collect data on a monthly basis for the following quality indicators: DVT prophylaxis Discharged on antithrombotics Patients with a-fib receiving anticoagulation Thrombolytic therapy administration Antithrombotic by end of day 2 Discharged on cholesterol meds Dysphagia screening Stroke education Smoking cessation education Assessed for Rehab Overall compliance with these indicators was on target but areas for improvement were noted in the following areas: stroke education, discharged on statin, thrombolytic therapy administration and patients with a-fib receiving anticoagulation. Aggressive action plans for each of these areas were developed and implemented. Initiatives included standardized electronic order sets, electronic admission, consult, history and physical templates with the quality indicators listed. Presentation of compliance results with a review of outliers were part of monthly section meetings. In order to understand process deviations further discussions with section chiefs resulted in investigation and resolution of issues that led to the variances. Hiring of a research registered nurse and a stroke coordinator were added to the existing stroke service team.

Results: Dramatic improvement was achieved with no indicator falling below <85.2% (85.2 out 100) for an entire year. Gold Plus achievement level with the American Stroke Association was achieved within a three year period. Target Stroke Honor Role was also achieved during this time period.

Conclusions: A cohesive project team was able to identify barriers, recommend process changes and ensure the implementation of change within the institution. Data collection and process revision is ongoing

Abstract 2399: Protocol for Rapid Acquisition and Interpretation of Head CT in Acute Stroke Patients Eligible for Thrombolysis

Introduction The American Heart Association’s quality improvement initiative, Target Stroke, is designed to reduce door-to-needle (DTN) times for IV r-tPA to improve patient outcomes. One of the quality indicators is time-to-CT scan and interpretation. Although, we were already meeting the recommended target, we sought to further enhance efficiency of this process in our institution.

Method We performed a retrospective chart review of patients with CT Brain Acute Stroke protocol orders from January to December 2010, which represents a one-year period after instituting changes to our CT protocol. Some of the changes included: improved emergency medical service communication, streamlined patient registration and emergency department (ED) training on time-sensitive stroke care elements. CT scan times were analyzed based on time ordered, time of completion, and radiology interpretation. Our review included DTN for IV r-tPA administration for acute stroke patients during the same time period.

Results Of the 571 acute stroke patients admitted through the ED during the study period, 12% received IV r-tPA. Of these, 79% received IV r-tPA within 60 minutes, with a mean (±SD) DTN time of 52 (±27) minutes. The relative efficiency of thrombolysis was attributed in part due to our fast-track CT head protocol process. The mean time from CT order to completion was 12 minutes and CT completion to verbal reporting to the ordering physician was 6 minutes.

Conclusion Using a multi-disciplinary approach for quality improvement in CT acquisition and interpretation times, we were able to enhance the efficiency of our overall DTN time. We believe that our protocol is easily adaptable in any Neurointensivist led stroke service, and would benefit patients on a national level to allow for more rapid administration of IV r-tPA by reducing delays in the CT head protocol. Developing a strong infrastructure that is hard-wired and part of the institutional culture resulted in decreased CT times along with 79% of stroke patients receiving r-tPA in less than 60 minutes. Are efforts have paid off; our hospital has been designated on the Target Stroke Honor Roll.

Abstract P260: Mind the Time: A Quality Improvement Project to Increase the Percent of Ischemic Stroke Patients Receiving Intravenous Tissue Plasminogen Activator within 60 Minutes after Arrival at the Emergency Department

Background and Purpose: Stroke is the third leading cause of death and leading cause of long term disability in the USA. Intravenous administration of tissue plasminogen activator (t-PA) is the only FDA approved medical therapy for treatment of patients with acute ischemic stroke. It is recommended by the American Heart Association that earlier treatment with t-PA within 90 minutes of symptoms may result in a more favorable patient outcome. Initiating t-PA for ischemic stroke patients within 60 minutes after Emergency Department (ED) triage is an indicator tracked by the Get With The Guidelines database. The purpose of our project was to increase the number of ischemic stroke patients receiving t-PA within 60 minutes after triage.

Methods: The Six Sigma® process model was applied in order to develop an understanding of variations in the times of triage to initiation of IV t-PA data. We assembled a multidisciplinary team to develop and measure aspects of our current protocols, analyze data, investigate and identify the causes of delays and form action plans to enhance our new process. We tracked the patient flow from first responder contact to thrombolysis time. As a result the team acknowledged that it was imperative to impact the early recognition of ischemic stroke patients in the field. This led to local and regional stroke educational programs. Our neuroscience team of physicians and nurses proceeded to educate over 850 emergency responders.

Results: Initial analysis of the baseline data showed that 56 % (5 of 9) of the ischemic stroke patients received intravenous t-PA within 60 minutes of triage. Once the stroke code process was implemented, 79 % (15 of 19) of ischemic stroke patients received intravenous t-PA within 60 minutes after triage. These results were obtained within 9 months of process implementation. Specific process changes included the use of a standard time clock, shorter CT scan turn around times, dedicated 24/7 ED pharmacists, quicker availability of medication administration pumps and ongoing feedback by all team members on the acute stroke process.

Conclusions: The stroke team was able to identify barriers, institute process changes and ensure the implementation of change from the prehospital community setting to the acute inhospital care.

Bringing research to the bedside: the role of induced hypothermia in cardiac arrest

Despite progress in resuscitative practices, there has been little improvement in mortality and neurologic morbidity outcomes after cardiac arrest. Updated resuscitative guidelines were published in 2005, and included changes in resuscitation measures and recommendations in postresuscitation interventions including induced hypothermia. Treatment with induced hypothermia after cardiac arrest for up to 24 hours has been shown to significantly improve the neurologic outcomes and mortality in patients with primary cardiac arrest who remain comatose after return of spontaneous circulation. St. Luke's Episcopal Hospital, a private, not-for-profit teaching hospital licensed for 949 beds located at the Texas Medical Center in Houston, Tex, has incorporated this research into practice. A multidisciplinary team led by a neurointensivist was formed to develop and implement a protocol to support induced hypothermia after cardiac arrest. Twenty-five patients have received induced hypothermia with a 74% survival rate. Of those who survived, 47% went home for a regular discharge, 29% transferred to acute rehabilitation, and 23% transferred to a long-term care facility.

Nursesʼ Perceptions of Open Visiting Hours in Neuroscience Intensive Care Unit

A quality improvement project was undertaken by Neuro-ICU nurses to determine possible effects from open visitation. From a quality improvement perspective, nurses' concerns were investigated along with their perceptions about open visitation to determine a need for visitation policy revision. Vast variability in nurses' interpretation and implementation of individualized open visitation policy suggested a need for the following: staff education about the policy and its implementation, a review of the literature to determine the validity of concerns about deleterious physiologic effects on neuroscience patients from visitation, and improved communication among nurses about visitation.
