Cerebrospinal Fluid Drainage in Patients with Acute Spinal Cord Injury: A Multi-Center Randomized Controlled Trial.

OBJECTIVE: The secondary phase of spinal cord injury (SCI) is characterized by ischemic injury. Spinal cord perfusion pressure (SCPP), calculated as the difference between mean arterial pressure (MAP) and intrathecal pressure (ITP), has arisen as a therapeutic target for improving outcomes. Cerebrospinal fluid drainage (CSFD) may reduce ITP and thereby increase SCPP. Randomized controlled trial to evaluate the safety and feasibility of CSFD to improve SCPP and outcomes after acute SCI. METHODS: Inclusion criteria included acute cervical SCI within 24 hours of presentation. All patients received lumbar drain placement and appropriate decompressive surgery. Patients randomized to the control group received MAP elevation only. Patients in the experimental group received MAP elevation and CSFD to achieve ITP <10 mmHg for 5 days. ITP and MAP were recorded hourly. Adverse events were documented and patients underwent functional assessments at enrollment, 72 hours, 90 days, and 180 days post-injury. RESULTS: Eleven patients were enrolled; 4 were randomized to receive CSFD. CSFD patients had a mean ITP of 5.3 ± 2.5 mmHg versus. 15 ± 3.0 mmHg in the control group. SCPP improved significantly, from 77 ± 4.5 mmHg in the control group to 101 ± 6.3 mmHg in the CSFD group (P < 0.01). Total motor scores improved by 15 ± 8.4 and 57 ± 24 points in the control and CSFD groups, respectively, over 180 days. No adverse events were attributable to CSFD. CONCLUSIONS: CSFD is a safe, effective mechanism for reducing ITP and improving SCPP in the acute period post-SCI. The favorable safety profile and preliminary efficacy should help drive recruitment in future studies.

Developing Physician Leadership in Hospital Policy Development: A Case Study of Resident-Driven Policy Initiatives in the Department of Neurosurgery at the University of Alabama at Birmingham.

The bulk of a resident's daily work is patient care related; however, other aspects of residency training are vital both to a resident's education and to the advancement of the field. Basic science and clinical research are the more common academic activities in which residents participate after completion of daily patient care objectives. Less frequently, residents participate in a process vital to the delivery of efficient, cost-effective, and safe patient care: hospital policy development. Two policies were identified as outdated or absent: (1) the process for the declaration of brain death and (2) a policy for the use of hypertonic saline in the Neurosciences Intensive Care Unit. The policies were rewritten after review of the existing policy (when applicable), other institutions' examples, national guidelines, and state and federal laws. Once written, proposals were reviewed by department leadership, hospital ethics, legal counsel, ad hoc specialty committees, the Medical Directors Council, and the Medical Executive Committee. After multiple revisions, each proposal was endorsed by the above bodies and ratified as hospital policy. Residents may make a substantial impact on patient care through active participation in the authorship and implementation of hospital policy. The inclusion of residents in policy development has improved the process for declaring brain death and management of patients with devastating neurological pathology. Resident involvement in hospital policy initiatives can be successful, valuable to the institution, and beneficial to patient care. Resident involvement is predicated on faculty and institutional support of such endeavors.

Reserved Bed Program Reduces Neurosciences Intensive Care Unit Capacity Strain: An Implementation Study.

BACKGROUND: Neurosciences intensive care units (NICUs) provide institutional centers for specialized care. Despite a demonstrable reduction in morbidity and mortality, NICUs may experience significant capacity strain with resulting supraoptimal utilization and diseconomies of scale. We present an implementation study in the recognition and management of capacity strain within a large NICU in the United States. Excessive resource demand in an NICU creates significant operational issues. OBJECTIVE: To evaluate the efficacy of a Reserved Bed Pilot Program (RBPP), implemented to maximize economies of scale, to reduce transfer declines due to lack of capacity, and to increase transfer volume for the neurosciences service-line. METHODS: Key performance indicators (KPIs) were created to evaluate RBPP efficacy with respect to primary (strategic) objectives. Operational KPIs were established to evaluate changes in operational throughput for the neurosciences and other service-lines. For each KPI, pilot-period data were compared to the previous fiscal year. RESULTS: RBPP implementation resulted in a significant increase in accepted transfer volume to the neurosciences service-line (P = .02). Transfer declines due to capacity decreased significantly (P = .01). Unit utilization significantly improved across service-line units relative to theoretical optima (P < .03). Care regionalization was achieved through a significant reduction in "off-service" patient placement (P = .01). Negative externalities were minimized, with no significant negative impact in the operational KPIs of other evaluated service-lines (P = .11). CONCLUSION: Capacity strain is a significant issue for hospital units. Reducing capacity strain can increase unit efficiency, improve resource utilization, and augment service-line throughput. RBPP implementation resulted in a significant improvement in service-line operations, regional access to care, and resource efficiency, with minimal externalities at the institutional level.

Independent Validation of the Colloid Cyst Risk Score to Predict Symptoms and Hydrocephalus in Patients with Colloid Cysts of the Third Ventricle.

BACKGROUND: The Colloid Cyst Risk Score (CCRS) was devised to identify patients with symptomatic colloid cyst and stratify risk of hydrocephalus. The CCRS considers patient age, presence of headache, colloid cyst diameter, fluid-attenuated inversion recovery hyperintensity, and location within the third ventricle. OBJECTIVE: The purpose of this study was to independently evaluate the validity of the CCRS. METHODS: Patients with a colloid cyst of the third ventricle were identified retrospectively from institutional billing records and radiology report archives. Patients without a confirmed diagnosis of colloid cyst of the third ventricle or magnetic resonance imaging of the brain were excluded. Data were collected via retrospective chart review. RESULTS: One hundred and fifty-six patients met inclusion and exclusion criteria. In our cohort, the CCRS stratified symptomatic patients and patients with hydrocephalus across all scores (P < 0.001). From CCRS 2 to 5, the percentage of symptomatic patients increased from 13% to 100%, whereas the percentage of patients with hydrocephalus increased from 8% to 83%. Simple logistic regression showed that total CCRS, headache, axial diameter, fluid-attenuated inversion recovery hyperintensity, and risk zone were all highly predictive of symptomatic status and hydrocephalus (P < 0.001). Logistic regression with receiver operating curves for the CCRS showed an area under the curve of 0.914 for symptomatic colloid cysts and an area under the curve of 0.892 for colloid cysts with hydrocephalus. CONCLUSIONS: Our data analysis validates the predictive value of the CCRS for both symptomatic status and hydrocephalus and supports the use of the CCRS in risk stratification and clinical decision making.

Is There an Association Between Physician Review Websites and Press Ganey Survey Results in a Neurosurgical Outpatient Clinic?

OBJECTIVE: Recent studies suggest a poor association between physician review websites and the validated metrics used by the Centers for Medicare and Medicaid Services. The purpose of this study was to evaluate the association between online and outpatient Press Ganey (PG) measures of patient satisfaction in a neurosurgical department. METHODS: We obtained PG survey results from one large academic institution's outpatient neurosurgery clinic. Popular physician review websites were searched for each of the faculty captured in the PG data. Average physician rating and percent Top Box scores were calculated for each physician. PG data were separated into new and established clinic visits for subset analysis. Spearman's rank correlation coefficients were calculated to determine associations. RESULTS: Twelve neurosurgeons were included. Established patients demonstrated greater PG scores as compared with new patients, with an average physician rating increase of 0.55 and an average Top Box increase of 12.5%. Online physician ratings were found to demonstrate strong agreement with PG scores for the entire PG population, new patient subset, and established patient subset (ρ = 0.77-0.79, P < 0.05). Online Top Box scores demonstrated moderate agreement with overall PG Top Box scores (ρ = 0.59, P = 0.042), moderate agreement with the new patient population Top Box scores (ρ = 0.56, P = 0.059), and weak agreement with established patient population Top Box scores (ρ = 0.38, P = 0.217). CONCLUSIONS: Our findings demonstrated a strong agreement between PG ratings and online physician ratings and a poorer correlation when comparing PG Top Box scores with online physician Top Box scores, particularly in the established patient population.

Current Topics in the Management of Acute Traumatic Spinal Cord Injury.

Acute traumatic spinal cord injury (SCI) affects more than 250,000 people in the USA, with approximately 17,000 new cases each year. It continues to be one of the most significant causes of trauma-related morbidity and mortality. Despite the introduction of primary injury prevention education and vehicle safety devices, such as airbags and passive restraint systems, traumatic SCI continues to have a substantial impact on the healthcare system. Over the last three decades, there have been considerable advancements in the management of patients with traumatic SCI. The advent of spinal instrumentation has improved the surgical treatment of spinal fractures and the ability to manage SCI patients with spinal mechanical instability. There has been a concomitant improvement in the nonsurgical care of these patients with particular focus on care delivered in the pre-hospital, emergency room, and intensive care unit (ICU) settings. This article represents an overview of the critical aspects of contemporary traumatic SCI care and notes areas where further research inquiries are needed. We review the pre-hospital management of a patient with an acute SCI, including triage, immobilization, and transportation. Upon arrival to the definitive treatment facility, we review initial evaluation and management steps, including initial neurological assessment, radiographic assessment, cervical collar clearance protocols, and closed reduction of cervical fracture/dislocation injuries. Finally, we review ICU issues including airway, hemodynamic, and pharmacological management, as well as future directions of care.

Towards Evidence-Based Guidelines in Neurological Surgery.

Neurological surgery practice is based on the science of balancing probabilities. A variety of clinical guidance documents have influenced how we collectively practice our art since the early 20th century. The quality of the science within these guidelines varies widely, as does their utility in positively shaping our practice. The guidelines development process in neurological surgery has evolved significantly over the last 30 yr. Historically based in expert opinion, as a specialty we have increasingly relied on objective medical evidence to guide our clinical practice. We assessed the changing practice guidelines development process and the impact of scientifically robust guidelines on patient care. The evolution of the guidelines development process in neurological surgery was chronicled. Several subspecialty guidelines were extracted and reviewed in detail. Their impact on practice patterns was evaluated. The importance of evidence-based research and practice guidelines development was discussed. Evidence-based practice guidelines serve to chronicle multiple acceptable treatment options and help us move towards more standardized care for specific disease processes. They help refute false "standards of care." Guidelines-based care supported by solid medical evidence has the potential to streamline patient care and improve patient outcomes. The guidelines development process identifies areas, issues, and strategies for which little medical evidence exists, as well as topics that need focused scientific investigation and future study. The production of evidence-based practice recommendations is a vital part of furthering our specialty. Guidelines development advances our science, augments the resident education process, and protects our practice from undue external influence.

Transitioning the Treatment Paradigm: How Early Palliative Care Service Involvement Affects the End-of-Life Course for Critically Ill Patients in the Neuro-Intensive Care Unit.

Background: Involvement of the palliative care service has potential for patient and family benefit in critically ill patients, regardless of etiology. Anecdotally, there is a lack of involvement of the palliative care (PC) service in the neuro-intensive care unit (neuro-ICU), and its impact has not been rigorously investigated in this setting. Objective: This study aims at assessing the effect of early involvement of the PC service on end-of-life care in the neuro-ICU. Design: Demographic variables and elements pertaining to the end-of-life care were obtained retrospectively via the electronic medical record from patients receiving their care at the University of Alabama at Birmingham Hospital neuro-ICU. The patient population was divided into two cohorts: patients who received PC services and patients who did not. Contingency analysis was performed to assess for associations with PC service involvement. Results: A total of 149 patients were included in the study. PC services were included in 56.4% of the cases. Involvement of the PC service led to more code status changes to comfort care-do-not-resuscitate p = 0.0021. This was more often a decremental change to less invasive measures rather than a direct change from full code to comfort care measures (p = 0.026). When PC specialists were involved, medications to treat anxiety/agitation, dyspnea/pain, and respiratory secretions were utilized more frequently (p < 0.001) and fewer procedures were performed on these critically ill patients within 48 hours of death (p < 0.001). Conclusion: Early involvement of the PC service has an impact on adjusting the treatment paradigm for patients suffering from devastating neurologic injuries. We recommend the creation of a standardized protocol to ensure early PC consultation in the neuro-ICU based on initial patient presentation parameters, imaging characteristics, and prognosis.
