Significant Mortality Associated With COVID-19 and Comorbid Cerebrovascular Disease: A Quantitative Systematic Review.

We report the first quantitative systematic review of cerebrovascular disease in coronavirus disease 2019 (COVID-19) to provide occurrence rates and associated mortality. Through a comprehensive search of PubMed we identified 8 cohort studies, 5 case series, and 2 case reports of acute cerebrovascular disease in patients with confirmed COVID-19 diagnosis. Our first meta-analysis utilizing the identified publications focused on comorbid cerebrovascular disease in recovered and deceased patients with COVID-19. We performed 3 additional meta-analyses of proportions to produce point estimates of the mortality and incidence of acute cerebrovascular disease in COVID-19 patients. Patient's with COVID-19 who died were 12.6 times more likely to have a history of cerebrovascular disease. We estimated an occurrence rate of 2.6% (95% confidence interval, 1.2-5.4%) for acute cerebrovascular disease among consecutively admitted patients with COVID-19. While for those with severe COVID-19' we estimated an occurrence rate of 6.5% (95% confidence interval, 4.4-9.6%). Our analysis estimated a rate of 35.5% for in-hospital mortality among COVID-19 patients with concomitant acute cerebrovascular disease. This was consistent with a mortality rate of 34.0% which we obtained through an individual patient analysis of 47 patients derived from all available case reports and case series. COVID-19 patients with either acute or chronic cerebrovascular disease have a high mortality rate with higher occurrence of cerebrovascular disease in patients with severe COVID-19.

Adult Trauma Patients With Thoracolumbar Injury Classification and Severity Score of 4: A Systematic Review.

STUDY DESIGN: Systematic review. OBJECTIVE: Evaluate characteristics of patients with thoracolumbar injury classification and severity (TLICS) score of 4 (To4) severity traumatic thoracolumbar injury. SUMMARY OF BACKGROUND DATA: The TLICS score is used to predict the need for operative versus nonoperative management in adult patients with traumatic thoracolumbar injury. Ambiguity exists in its application and score categorization. METHODS: A systematic review of the literature was performed. The databases of MEDLINE, Embase, Web of Science, and Cochrane Review were queried. Studies included adults with traumatic thoracolumbar injury with assigned TLICS score and description of management strategy. RESULTS: A total of 16 studies met inclusion criteria representing 1911 adult patients with traumatic thoracolumbar injury. There were 503 (26.32%) patients with To4, of which 298 (59.24%) were operative. Studies focusing on the thoracolumbar junction and AO Type A fracture morphology had To4 patient incidences of 11.15% and 52.94%, respectively. Multiple studies describe better quality of life, pain scores, and radiographic outcomes in To4 who underwent operative treatment patients. CONCLUSION: To4 injuries are more commonly AO Type A and located in the thoracolumbar junction in adult patients with traumatic thoracolumbar injury. Despite ambiguous recommendations regarding treatment provided by TLICS, outcomes favor operative intervention in this subset of traumatic thoracolumbar injury patients.

Neurosurgery perception of Enhanced Recovery After Surgery (ERAS) protocols.

Enhanced Recovery After Surgery (ERAS) protocols are widespread in several fields, particularly general surgery, and attempt to deliver surgical care at a lower cost while also improving patient outcomes. However, few institutions have implemented ERAS protocols in neurosurgery. As such, a survey of neurosurgeons on the current state of ERAS in neurosurgery was conducted to provide insight on scaling the practice nationally. A 15-question survey was designed to assess the implementation of andsatisfaction with ERAS protocols at individual institutions. A total of 39 responses were collected from 38 unique institutions. 58.9%(N = 23) reported implementation of neurosurgical ERAS protocols. 52.1% (N = 12) of the responses were neurosurgeons at academic institutions withneurosurgical residency programs. Most neurosurgeons used ERAS protocolsfor spine cases (N = 23), with only 17.3% (N = 4) employing ERAS protocolsfor cranial cases. 69.5% (N = 16) of survey participants reported that thedesign and implementation of ERAS was a multidisciplinary effort acrossmany departments, including neurosurgery, anesthesia, and pharmacy.Decreased costs and intensive care unit (ICU) admission were reported tobe unanticipated benefits of ERAS implementation. Unanticipated challenges to implementation of new protocols included difficulties withelectronic medical record (EMR) integration, agreement of protocoldetails amongst stakeholders, uniform implementation of protocols by allneurosurgeons, and lack of adaptability by multidisciplinary staff. Meandepartment satisfaction with ERAS protocol implementation was 4.00 +/- 0.81 (N = 22) on a 5-point Likert scale.

Modern Training and Credentialing in Neuroendovascular Acute Ischemic Stroke Therapy.

BACKGROUND: Acute ischemic stroke (AIS) remains a significant source of morbidity and mortality worldwide. Multiple recent randomized clinical trials for AIS patients presenting with large vessel occlusion have demonstrated radical improvement in outcomes with mechanical thrombectomy (MT), which is now recognized as the new standard of care for patients presenting up to 24 hr. OBJECTIVE: To provide a perspective on training and credentialing requirements for practitioners in this field. METHODS: Relevant articles were systematically searched and analyzed. Standards for Reporting Qualitative Research guidelines were utilized. RESULTS: : The Committee for Advanced Subspecialty Training (CAST) brings together the principal specialties of Radiology, Neurology, and Neurosurgery. Their training standards document the most recent consensus on training for neuroendovascular surgery (NES) and include the endovascular treatment of AIS as a part of the field of NES. This unified consensus represents a significant landmark in the evolution of stroke therapy. Presently, training at most centers follows an apprenticeship type model. Simulation methods and objective performance metrics have not been widely incorporated. Maintenance of proficiency has not been conclusively addressed reflecting the overall developing nature of the field. CONCLUSION: The evolution of the standard of care interventional therapy for large vessel AIS utilizing MT raises concerns regarding work force needs, training standards, competency, and credentialing requirements for practitioners. The CAST framework represents the most modern and flexible approach for both individuals and training programs. Methods based on objective performance metrics utilizing simulation as primary vehicle may be the logical next steps in the evolution of NES.
