Quality Improvement in Neurocritical Care.

Quality improvement is key to advancing outcomes for neurocritically ill patients. Variation in neurocritical care practice can lead to differences in health outcomes and contribute to health disparities. The implementation of evidence-based best practice standards represents a major opportunity to improve their care. Neurocritical care performance measures have recently been developed and may be used to target high priority areas for improvement. In addition, neurocritical care clinicians should be aware of the heavily weighted pay-for-performance and publicly reported performance measures that are directly relevant to neurocritical care practice.

Perceptions Regarding the SARS-CoV-2 Pandemic's Impact on Neurocritical Care Delivery: Results From a Global Survey.

BACKGROUND: The SARS-CoV-2 (COVID-19) pandemic has impacted many facets of critical care delivery. METHODS: An electronic survey was distributed to explore the pandemic's perceived impact on neurocritical care delivery between June 2020 and March 2021. Variables were stratified by World Bank country income level, presence of a dedicated neurocritical care unit (NCCU) and experiencing a COVID-19 patient surge. RESULTS: Respondents from 253 hospitals (78.3% response rate) from 47 countries (45.5% low/middle income countries; 54.5% with a dedicated NCCU; 78.6% experienced a first surge) participated in the study. Independent of country income level, NCCU and surge status, participants reported reductions in NCCU admissions (67%), critical care drug shortages (69%), reduction in ancillary services (43%) and routine diagnostic testing (61%), and temporary cancellation of didactic teaching (44%) and clinical/basic science research (70%). Respondents from low/middle income countries were more likely to report lack of surge preparedness (odds ratio [OR], 3.2; 95% confidence interval [CI], 1.8-5.8) and struggling to return to prepandemic standards of care (OR, 12.2; 95% CI, 4.4-34) compared with respondents from high-income countries. Respondents experiencing a surge were more likely to report conversion of NCCUs and general-mixed intensive care units (ICUs) to a COVID-ICU (OR 3.7; 95% CI, 1.9-7.3), conversion of non-ICU beds to ICU beds (OR, 3.4; 95% CI, 1.8-6.5), and deviations in critical care and pharmaceutical practices (OR, 4.2; 95% CI 2.1-8.2). Respondents from hospitals with a dedicated NCCU were less likely to report conversion to a COVID-ICU (OR, 0.5; 95% CI, 0.3-0.9) or conversion of non-ICU to ICU beds (OR, 0.5; 95% CI, 0.3-0.9). CONCLUSION: This study reports the perceived impact of the COVID-19 pandemic on global neurocritical care delivery, and highlights shortcomings of health care infrastructures and the importance of pandemic preparedness.

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.

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.

Quality improvement in neurocritical care: current state and looking to the future.

PURPOSE OF REVIEW: Neurocritical care has matured as a field and there is now a growing body of literature on the subject of quality improvement in neurocritically ill patients. This review will highlight major recent contributions in this field and discuss future directions. RECENT FINDINGS: Articles published in the past 18 months have evaluated neurocritical care unit staffing, structure, and disease-specific protocols including subarachnoid hemorrhage and severe traumatic brain injury management. An assessment of current quality improvement practices in neurocritical care was also conducted. A neurocritical care-specific metric bundle is being proposed. SUMMARY: The quality improvement movement is gaining momentum in neurocritical care with evaluation of general medical and surgical critical care quality improvement approaches in this specific patient population. Future work should focus on improving systems of neurocritical care delivery through iterative evaluation of structure, staffing, minimizing unnecessary variation, and evaluation of neurocritical care-specific metrics.

A Perspective from the Neurocritical Care Society and the Society of Critical Care Medicine: Team-Based Care for Neurological Critical Illness.

The Neurocritical Care Society and the Society of Critical Care Medicine have worked together to create a perspective regarding the Standards of Neurologic Critical Care Units (Moheet et al. in Neurocrit Care 29:145-160, 2018). The most neurologically ill or injured patients warrant the highest standard of care available; this supports the need for defining and establishing specialized neurological critical care units. Rather than interpreting the Standards as being exclusionary, it is most appropriate to embrace them in the setting of team-based care. Since there are many more patients than there are highly specialized beds, collaborative care and appropriate transfer agreements are essential in promoting excellent patient outcomes. This viewpoint addresses areas of clarification and emphasizes the need for collegiality and partnership in delivering the best specialty critical care to our patients.

Neurocritical Care Quality Improvement Practices: A Survey of Members of the Neurocritical Care Society.

BACKGROUND: To describe current state of quality improvement (QI) processes implemented in neurocritical care units (NCCU). METHODS: A 27-question-survey was sent to 2000 members (physicians, nurses, and pharmacists) of the Neurocritical Care Society. We describe the prevalence of QI, satisfaction with existing QI processes, barriers to NCCU QI, awareness of stroke (STK, CSTK), stroke get with the guidelines (GWTG), trauma quality improvement program (TQIP) and American Academy of Neurology (AAN) performance measures. RESULTS: The response rate was 22.5%; 73.7% of respondents were from US teaching hospitals, 87.9% practiced in dedicated neurocritical care units, and 43.4% in a program with a NCC fellowship. 44.6 % reported a dedicated NCCU QI program. Overall, 42% of the respondents reported satisfaction with existing NCCU QI processes. External ventricular drain infection was the most commonly tracked NCC QI metric (69.6%). Respondents indicated the highest level of awareness for CSTK (87.5%), STK (81.8%), and GWTG (81.8%), but indicated a relative lack of awareness for TQIP (42.7%), and AAN (46.2%) performance measures. Insufficient hospital (57.7%) and departmental support (36.5%) were reported common barriers to the successful implementation of an NCCU QI program. CONCLUSION: A dedicated staffed NCCU QI program occurs in a minority of NCC units, and the lack of such programs may lead to clinician dissatisfaction. Institutional and departmental support may be critical elements of a successful and satisfactory implementation of NCCU QI.

Intracerebral Hemorrhage in Women: A Review with Special Attention to Pregnancy and the Post-Partum Period.

Non-traumatic intracranial hemorrhage includes subarachnoid hemorrhage, subdural hemorrhage, and intracerebral hemorrhage (ICH), which can be classified as primary or secondary. Primary ICH is due to arterial hypertension or cerebral amyloid angiopathy, and secondary ICH is due to cerebral vascular malformations, coagulopathies, infectious complications, brain tumors, and illicit stimulant drug use. This review explores the epidemiology and management of non-traumatic ICH in women, with a focus on pregnancy and the post-partum period, defined as 6 weeks post-delivery.

Standards for Neurologic Critical Care Units: A Statement for Healthcare Professionals from The Neurocritical Care Society.

Neurocritical care is a distinct subspecialty focusing on the optimal management of acutely ill patients with life-threatening neurologic and neurosurgical disease or with life-threatening neurologic manifestations of systemic disease. Care by expert healthcare providers to optimize neurologic recovery is necessary. Given the lack of an organizational framework and criteria for the development and maintenance of neurological critical care units (NCCUs), this document is put forth by the Neurocritical Care Society (NCS). Recommended organizational structure, personnel and processes necessary to develop a successful neurocritical care program are outlined. Methods: Under the direction of NCS Executive Leadership, a multidisciplinary writing group of NCS members was formed. After an iterative process, a framework was proposed and approved by members of the writing group. A draft was then written, which was reviewed by the NCS Quality Committee and NCS Guidelines Committee, members at large, and posted for public comment. Feedback was formally collated, reviewed and incorporated into the final document which was subsequently approved by the NCS Board of Directors.

Early and Severe Symptomatic Cerebral Vasospasm After Mild Traumatic Brain Injury.

BACKGROUND: Symptomatic cerebral vasospasm has been reported in a low percentage of patients with moderate or severe traumatic brain injury (TBI) as defined by Glasgow Coma Scale (GCS) score. We present a case of mild TBI (GCS score 14) complicated by early and severe symptomatic cerebral vasospasm. CASE DESCRIPTION: A 63-year-old woman was admitted following mild TBI with a GCS score of 14. Concurrent with the onset of sonographic vasospasm, the patient developed severe neurologic symptoms consistent with ischemia of the left middle cerebral artery territory. Confounding causes of these symptoms were excluded. Each occurrence of these symptoms resolved with intra-arterial calcium channel blocker therapy. CONCLUSIONS: Early and severe symptomatic vasospasm may occur as a complication of mild TBI. GCS score alone may be an inadequate risk predictor of symptomatic cerebral vasospasm. Aggressive interventional management may be justified, such as with intra-arterial calcium channel blockers, to optimize the likelihood of a favorable outcome.

Pharmacologic cardioversion with intravenous amiodarone is likely safe in neurocritically Ill patients.

Neurological injury is often associated with cardiac abnormalities, including electrophysiological issues. Cardioversion of acute atrial fibrillation (<48h' duration) without anticoagulation carries about a 0.7% risk of thromboembolism. There is limited data on managing acute atrial fibrillation specifically in the neuroscience intensive care unit (NSICU) setting. We sought to determine the safety of using intravenous (IV) amiodarone for restoring sinus rhythm in patients with presumed new onset atrial or ventricular tachycardia after neurological injury. We conducted a retrospective review of consecutive patients admitted to our NSICU between June 2011 and March 2015 with a primary neurological diagnosis and new onset tachyarrhythmias who received IV amiodarone. Baseline demographics and presence of known risk factors for atrial fibrillation were recorded. The primary end point was new onset stroke. 48 patients were included for the final analysis. No patients developed new stroke after receiving IV amiodarone. The average follow up period was 14.0days. The majority of patients did not have the pre identified risk factors for atrial fibrillation. Ischemic stroke and traumatic brain injury were the most common admitting diagnoses. We conclude that in patients with primary neurological injury, use of IV amiodarone for rhythm control of acute onset atrial fibrillation carries a low risk of cardioembolic stroke in the first 2weeks. Further investigation, including prospective studies, with larger samples and longer follow up periods is warranted.

Neurological Prognostication of Cardiac Arrest in an Era of Extracorporeal Membrane Oxygenation.

A neuron-specific enolase level greater than 33 ng/mL at days 1 to 3 or status myoclonus within 1 day are traditional indicators of poor neurological prognosis in survivors of cardiac arrest. We report the case of a 70-year-old man who received extracorporeal membrane oxygenation following cardiac arrest. Despite having both an elevated neuron-specific enolase concentration of 68 ng/mL and status myoclonus, he made an excellent neurological recovery. The value of traditional markers of poor prognosis such as elevated neuron-specific enolase or status myoclonus has not been systematically validated in patients treated with extracorporeal membrane oxygenation or therapeutic hypothermia. Straightforward application of practice guidelines in these cases may result in tragic outcomes. This case underscores the need for reliable prognostic markers that account for recent advances in cardiopulmonary and neurological therapies.

Systematic Quality Assessment of Published Antishivering Protocols.

Shivering is a common side effect of targeted temperature modulation and general anesthesia. Antishivering strategies often employ a stepwise approach involving both pharmacological and physical interventions. However, approaches to treat shivering are often empiric and vary widely across care environments. We evaluated the quality of published antishivering protocols and guidelines with respect to methodological rigor, reliability, and consistency of recommendations.Using 4 medical databases, we identified 4027 publications that addressed shivering therapy, and excluded 3354 due to lack of relevance. After applying predefined eligibility criteria with respect to minimal protocol standards, 18 protocols/guidelines remained. Each was assessed using a modified Appraisal of Guidelines for Research and Evaluation II (mAGREE II) instrument containing 23 quality items within 6 domains (maximal score 23). Among 18 protocols/guidelines, only 3 incorporated systematically reviewed recommendations, whereas 15 merely targeted practice standardization. Fifteen of 18 protocols/guidelines addressed shivering during therapeutic cooling in which skin counterwarming and meperidine were most commonly cited. However, their mAGREE II scores were within the lowest tertile (1 to 7 points) and the median for all 18 protocols was 5. The quality domains most commonly absent were stakeholder involvement, rigor of development, and editorial independence. Three of 18 protocols/guidelines addressed postanesthetic antishivering. Of these, the American Society of Anesthesiologists guidelines recommending forced-air warming and meperidine received the highest mAGREE II score (14 points), whereas the remaining 2 recommendations had low scores (<5 points).Current published antishivering protocols/guidelines lack methodological rigor, reliability, and strength, and even the highest scoring of the 18 protocols/guidelines fulfilled only 60% of quality items. To be consistent with evidence-based protocol/guideline development processes, future antishivering treatment algorithms should increase methodological rigor and transparency.

Optimizing Outcomes for Mechanically Ventilated Patients in an Era of Endovascular Acute Ischemic Stroke Therapy.

Endovascular mechanical thrombectomy is a new standard of care for acute ischemic stroke (AIS). The majority of these patients receive mechanical ventilation (MV), which has been associated with poor outcomes. The implication of this is significant, as most neurointerventionalists prefer general compared to local anesthesia during the procedure. Consequences of hemodynamic and respiratory perturbations during general anesthesia and MV are thought to contribute significantly to the poor outcomes that are encountered. In this review, we first describe the unique risks associated with MV in the specific context of AIS and then discuss evidence of brain goal-directed approaches that may mitigate these risks. These strategies include an individualized approach to hemodynamic parameters (eg, adherence to a minimum blood pressure goal and adequate volume resuscitation), respiratory parameters (eg, arterial carbon dioxide optimization), and the use of ventilator settings that optimize neurological outcomes (eg, arterial oxygen optimization).

Accuracy of neurovascular fellows' prognostication of outcome after subarachnoid hemorrhage.

BACKGROUND AND PURPOSE: The purpose of this study was to determine the accuracy and optimal timing of physician prognostication in patients with subarachnoid hemorrhage, a prototypical neurological disease characterized by variable outcomes and frequent disability. METHODS: From October 2009 to April 2010, treating neurologists at a tertiary care academic medical center made daily predictions of the modified Rankin Scale at 6 months for consecutive patients with subarachnoid hemorrhage. Actual functional outcomes at 6 months were determined by phone interview and dichotomized into good (modified Rankin Scale 0-2) and poor (modified Rankin Scale 3-6) outcomes. Descriptive statistics were used to assess the accuracy of prognostications. Multiple logistic regression and generalized estimating equations were used to assess changes in prognostication accuracy over time and the relationship between prognostication accuracy and clinical factors. RESULTS: Physicians made 648 prognostications for 66 patients. Overall accuracy ranged from 78% to 88%. Among patients predicted to have a good outcome, 81% (95% CI, 71%-92%) actually had a good outcome, whereas 88% (95% CI, 77%-99%) of patients predicted to do poorly had poor outcomes. No significant trends were seen in prognostication accuracy over time during the hospital course (P=0.72). Increasing age, infection, mechanical ventilation, hydrocephalus, and seizures all significantly worsened physician accuracy. CONCLUSIONS: Neurologists were generally but not perfectly accurate in their prognostications of functional outcomes. The accuracy of prognoses did not correlate with the hospital day on which they were made but was affected by clinical factors that can cloud the neurological examination.

Ventilator-associated pneumonia in a neurologic intensive care unit does not lead to increased mortality.

BACKGROUND: Ventilator-associated pneumonia (VAP) is the most common nosocomial infection among medical intensive care unit (ICU) patients and is associated with increased mortality and length of stay (LOS). Neurologic disease is a risk factor for VAP development, but the relationship between VAP and outcomes in patients admitted to the ICU for neurologic reasons remains largely unknown. METHODS: All mechanically ventilated patients over a 2-year period with neurovascular disease were included in a retrospective study. Data collected included patient demographics, dates of admission and discharge, LOS, and ventilator hours. Comparisons between neurologic patients who did and did not develop VAP were made using univariate and multivariate analysis. RESULTS: Of 585 intubated neurovascular patients, 24 (4.1%) developed VAP. Compared with those who did not develop VAP, those with VAP were younger (51.8 +/- 13.9 years vs. 58.8 +/- 15.9 years, P = 0.03), had increased LOS (32.6 +/- 29.2 days vs. 14.5 +/- 7.8 days, P < 0.001), and more ventilator hours (272 +/- 257 h vs. 85.9 +/- 140 h, P < 0.001). There was no difference in mortality between patients with and without VAP (25.0% vs. 28.3%, P = 0.72). VAP was not an independent predictor of mortality in a multivariate model (OR 1.11, 95% CI 0.37-3.30, P = 0.855). CONCLUSIONS: VAP in neurocritical care patients is associated with increased LOS and ventilator hours, but is not associated with increased mortality, contrary to prior studies in medical ICU patients.

Which patients benefit from carotid stenting? What recent trials show.

So far, angioplasty with stenting of the carotid arteries does not seem to offer any clear advantage over traditional carotid endarterectomy for patients with symptomatic or asymptomatic stenosis. This paper reviews recent and ongoing studies of carotid revascularization, with conclusions on how these treatments should be used, based on what we know now.
