Automated and Optimized Neurosurgery Scheduling System Improves Resident Satisfaction.

BACKGROUND AND OBJECTIVES: Neurosurgery residency involves a complex structure with multiple hospitals, services, and clinic days, leading to challenges in creating equitable call schedules. Manually prepared scheduling systems are prone to biases, error, and perceived unfairness. To address these issues, we developed an automated scheduling system (Automated Optimization of Neurosurgery Scheduling System [AONSS]) to reduce biases, accommodate resident requests, and optimize call variation, ultimately enhancing the educational experience by promoting diverse junior-senior-attending relationships. METHODS: AONSS was developed and tailored to the University of Florida program, with inaugural use in 2021-2022 and mandatory implementation in the 2022-2023 academic year. 2019-2021 academic years were used as control. Residents were surveyed using Google Forms before and after implementation to assess its impact. Outcome measures included call and pairing variations, duty hours, as well as subjective factors such as satisfaction, fairness, and perceived biases. RESULTS: Twenty-six residents (28%-39% female/year) were included in the study. AONSS was used for 6/13 blocks during the 2021-2022 academic year and 13/13 blocks for the 2022-2023 academic year. Overall call variation reduced by 70%. All other objective secondary measures have improved with AONSS. Weekly and monthly duty hours were reduced and less varied. Satisfaction scores improved from 21% reporting being somewhat satisfied or very satisfied to 90%. Fairness scores improved from 43% reporting being somewhat fair or very fair to 95%. Perception of gender bias decreased from 29% to 0%. No resident felt there was racial bias in either system. CONCLUSION: Our newly developed automated scheduling system effectively reduces variation among calls in a complex neurosurgery residency, which, in return, was found to increase residents' satisfaction with their schedule, improve their perception of fairness with the schedule, and has completely removed the perception of sexual bias in a program that has a large percentage of females. In addition, it was found to be associated with decreased duty hours.

Evaluation of patients referred to the spine clinic via telemedicine and the impact on diagnosis and surgical decision-making.

OBJECTIVE: Telemedicine encounters are expanding in utility for outpatient care and evaluation, partially as a necessity during the COVID-19 pandemic. It is unclear if telemedicine evaluation is comparable to in-person assessment of patients with spinal pathology undergoing surgical consultation. The objective of this study was to determine if treatment plans change for spine patients evaluated in person following an initial telemedicine consultation. METHODS: Patients referred to the authors' comprehensive spine center were evaluated first via telemedicine and then in clinic. Telemedicine evaluations were conducted via video evaluation with an attending surgeon. Demographic data including age, gender, and distance traveled from the clinic were retrospectively recorded. A chart review retrieved symptoms, radiographic details, and past medical history. The primary outcome was if the treatment plan changed (plan change [PC]) after seeing the patient in the clinic. Chi-square tests and binary logistical regression produced uni- and multivariate analyses. RESULTS: There were 152 new patients seen via telemedicine and in person. Pathology was present in the cervical (28.3%), thoracic (9.9%), and lumbar (61.8%) spine. The most common symptom was pain (72.4%), followed by radiculopathy (66.4%), weakness (26.3%), myelopathy (15.1%), and claudication (12.5%). There were 37 patients (24.3%) for whom there was a PC after clinic evaluation, and of those, only 5 (3.3%) were due to physical examination (PCPE) findings. On univariate analysis, a longer duration between telemedicine and clinic visit (odds ratio [OR] 1.094 per 7 days, p = 0.003), having pathology in the thoracic spine (OR 3.963, p = 0.018) and lack of sufficient imaging (OR 25.455, p < 0.0001) were predictive of a PC. Having pathology in the cervical spine (OR 9.538, p = 0.047) and adjacent-segment disease (OR 11.471, p = 0.010) were predictive of a PCPE. CONCLUSIONS: This study demonstrates that telemedicine may be an effective modality for the initial evaluation of spine surgical patients, without compromising decision-making in the absence of an in-person physical examination.

Healing Exposed Calvarial Hardware Using Negative-Pressure Wound Therapy and Vashe Wound Solution: Case Report.

OBJECTIVE: The management of cranioplasty infections has historically been explantation followed by delayed reimplantation/reconstruction. This treatment algorithm necessitates surgery, tissue expansion, and prolonged disfigurement. In this report, the authors describe a treatment approach consisting of serial vacuum-assisted closure (VAC) with hypochlorous acid (HOCl) solution (Vashe Wound Solution; URGO Medical) as a salvage strategy. METHODS: A 35-year-old man who sustained head trauma, neurosurgical complications, and severe syndrome of the trephined (SOT; devastating neurologic decline treated by cranioplasty) underwent titanium cranioplasty with free flap. Three weeks postoperation, he presented with pressure-related wound dehiscence/partial flap necrosis, exposed hardware, and bacterial infection. Given the severity of his precranioplasty SOT, hardware salvage was critical. He was treated with serial VAC with HOCl solution for 11 days followed by VAC for 18 days and definitive split-thickness skin graft placement over resulting granulation tissue. Authors also conducted a literature review of cranial reconstruction infection management. RESULTS: The patient remained healed 7 months postoperatively without recurrent infection. Importantly, his original hardware was retained, and his SOT remained resolved. Findings from the literature review support the use of conservative modalities to salvage cranial reconstructions without hardware removal. CONCLUSIONS: This study investigates a new strategy for managing cranioplasty infections. The VAC with HOCl solution regimen was effective in treating the infection and salvaging the cranioplasty, thus obviating the complications associated with explantation, new cranioplasty, and recurrence of SOT. There is limited literature on the management of cranioplasty infections using conservative treatments. A larger study to better determine the efficacy of VAC with HOCl solution is underway.

The Enhanced Recovery After Surgery pathway for posterior cervical surgery: a retrospective propensity-matched cohort study.

OBJECTIVE: The Enhanced Recovery After Surgery (ERAS) protocol is a comprehensive, multifaceted approach aimed at improving postoperative outcomes. It incorporates a range of strategies to promote early and more effective recovery, including reducing pain, complications, and length of stay, without increasing readmission rate. To date, ERAS for spine surgery patients has been primarily limited to lumbar surgery and anterior cervical decompression and fusion (ACDF). ERAS has not been previously studied for posterior cervical surgery, which may present a greater opportunity for improvement in patient outcomes with ERAS than ACDF. This single-institution, multi-surgeon study assessed the impact of an ERAS protocol in patients undergoing posterior cervical decompression surgery. METHODS: This study included a retrospective consecutive patient cohort with controls that were propensity matched for age, body mass index, sex, home opioid use, surgical levels, Nurick grade, and smoking status. In addition, consecutive patients who underwent posterior cervical decompression surgery for degenerative disease from December 2014 to December 2021 were included. ERAS was implemented in December 2018. Demographic, perioperative, clinical, and radiographic information was gathered. Regression models were created to evaluate length of stay, physiological function, pain levels, and opioid use. The primary focus was length of stay, with secondary outcomes including timing of ambulation, bowel movement, and voiding; daily pain scores; opioid consumption; discharge status; 30-day readmission rates; and reoperation rates. RESULTS: There were 366 patients included in the study, all of whom were included in multivariate models, and 254 (127 in each cohort) were included on the basis of matching. After propensity matching, patient characteristics, operative procedures, and operative duration were similar between groups. The ERAS cohort had a significantly improved length of stay (3.2 vs 4.7 days, p < 0.0001) and home discharge rate (80% vs 50%, p < 0.001) without an increase in readmission rate. The ERAS cohort had an earlier day of the first ambulation (p = 0.003), bowel movement (p = 0.014), and voiding (p = 0.001). ERAS demonstrated a significantly lower composite complication rate (1.1 vs 1.8, p < 0.0001). ERAS resulted in better maximum pain scores (p = 0.043) and trended toward improved mean pain scores (p = 0.072), although total opioid use was similar. CONCLUSIONS: Implementing a novel ERAS protocol significantly improved length of stay, return of physiological function, home discharge, complications, and maximum pain score after posterior cervical surgery.

Focused selection of open cerebrovascular cases for residents interested in cerebrovascular neurosurgery.

INTRODUCTION: National and international trends continue to show greater emphasis on endovascular techniques for the treatment of cerebrovascular disease. The cerebrovascular neurosurgeon however must be adequately equipped to treat these patients via both open and endovascular techniques. METHODS: The decline in open cerebrovascular cases for aneurysm clipping has forced many trainees to pursue open cerebrovascular fellowships to increase case volume. An alternative strategy has been employed at our institution, which is early identification of subspecialty focus with resident driven self-selection of open cerebrovascular cases. RESULTS: This has allowed recent graduates to obtain enfolded endovascular training and a significant number of open cerebrovascular cases in order to obtain competence and exposure. DISCUSSION: We advocate for further self-selection paradigms supplemented with simulation training in order to obviate the need for extended post-residency fellowships.

Facial Fractures: Independent Prediction of Neurosurgical Intervention.

Context Over half of patients with facial fractures have associated traumatic brain injury (TBI). Based on force dynamic cadaveric studies, Le Fort type 2 and 3 fractures are associated with severe injury. Correlation to neurosurgical intervention is not well characterized. Aims This study characterizes fracture pattern types in patients requiring neurosurgical intervention and assesses whether this is different from those not requiring intervention. Settings and Design Retrospective data was collected from the trauma registry from 2010 to 2019. Methods and Materials Patients over 18 years, with confirmed facial fracture, reported TBI, available neuroimaging, and hospital admission were included. Statistical Analysis Retrospective contingency analysis with fraction of total comparison was used with chi-square analysis for demographic and injury characteristic data. Results Note that 1,001 patients required no neurosurgical intervention and 171 required intervention. The intervention group had a significantly greater number of patients with Glasgow Coma Scale (GCS) < 8 compared with the nonintervention group. Subset analysis revealed a twofold increase in Le Fort type 2 fractures and notable increase in Le Fort type 3 and panfacial fractures in the intervention group. Patients requiring craniectomy, craniotomy, or burr holes were much more likely to have Le Fort type 2 or 3 fractures compared with those only requiring external ventricular drains or intracranial pressure monitoring. Subset analysis accounting for GCS supported these results. Conclusion Le Fort type 2 and type 3 fractures are significantly associated with requiring neurosurgical intervention. An improved algorithm for managing these patients has been proposed in the discussion. Ongoing work will focus on validating and refining the algorithm to improve patient care.

Clinical risk factors associated with cerebrospinal fluid leak in facial trauma: A retrospective analysis.

OBJECTIVE: Cerebrospinal fluid (CSF) leak occurs most commonly following skull fracture, with a CSF leakage complicating up to 2% of all head traumas. This study aims to identify demographic and injury characteristics correlated with the highest risk of CSF leak in patients with known facial fractures. METHODS: Retrospective data was collected from a previously described trauma registry from 2010 to 2019. Patients over 18 years old with any type of facial fracture, known CSF leak status, available neuroimaging, and hospital admission were included. Chi-Square analysis for demographic and injury characteristic data were utilized. RESULTS: A total of 79 patients with CSF leak and 4907 patients without CSF leak were included in the database. Patients with CSF leak tended to be younger than those without CSF leak (38.45 +/- 0.28 vs 44.08 +/- 0.28, M +/- SE, p = 0.0197). CSF leak depended on the mechanism of injury (MOI; X2 =27.02, df=2, p = 0.0000013), with CSF leak rates highest in penetrating injuries (4.87%) and motor vehicle accidents (1.78%) compared to blunt injuries (0.95%); age did not significantly differ between the MOI groups (p = 0.11). CSF leak was also more common in patients with a lower Glasgow coma scale (GCS; 7.95 +/- 0.58 vs 12.21 +/- 0.10, p = 10-15), LeFort type 2&3 and pan-facial fractures compared to all other facial fracture types (8.9% vs 1.2%, p = 10-15), and radiographic midline shift (29.4% vs 9.1%, p = 10-15). There was a trend towards a higher proportion of males in those with CSF leak compared to those without (83.3% vs 73.7% males, p = 0.073), and in patients with prolonged loss of consciousness (LOC; 9.43% with LOC > 1 h vs 2.69% LOC < 1 h, p = 0.056). CONCLUSION: Facial fractures often present with CSF leak, and certain demographic and injury risk factors including younger age, worse GCS score, evidence of midline shift, and certain mechanisms of injury (penetrating and motor vehicle) are correlated with increased risk and warrant close screening and follow-up for CSF leak detection. LeFort type 2&3 and pan-facial fractures are at high risk of CSF leak.

Effects of Patient and Surgery Characteristics on Persistent Postoperative Pain: A Mediation Analysis.

OBJECTIVE: Acute postoperative pain intensity is associated with persistent postsurgical pain (PPP) risk. However, it remains unclear whether acute postoperative pain intensity mediates the relationship between clinical factors and persistent pain. MATERIALS AND METHODS: Participants from a mixed surgical population completed the Brief Pain Inventory and Pain Catastrophizing Scale before surgery, and the Brief Pain Inventory daily after surgery for 7 days and at 30 and 90 days after surgery. We considered mediation models using the mean of the worst pain intensities collected daily on each of postoperative days (PODs) 1 to 7 against outcomes of worst pain intensity at the surgical site endpoints reflecting PPP (POD 90) and subacute pain (POD 30). RESULTS: The analyzed cohort included 284 participants for the POD 90 outcome. For every unit increase of maximum acute postoperative pain intensity through PODs 1 to 7, there was a statistically significant increase of mean POD 90 pain intensity by 0.287 after controlling for confounding effects. The effects of female versus male sex (m=0.212, P=0.034), pancreatic/biliary versus colorectal surgery (m=0.459, P=0.012), thoracic cardiovascular versus colorectal surgery (m=0.31, P=0.038), every minute increase of anesthesia time (m=0.001, P=0.038), every unit increase of preoperative average pain score (m=0.012, P=0.015), and every unit increase of catastrophizing (m=0.044, P=0.042) on POD 90 pain intensity were mediated through acute PODs 1 to 7 postoperative pain intensity. DISCUSSION: Our results suggest the mediating relationship of acute postoperative pain on PPP may be predicated on select patient and surgical factors.

Nuchal thickness and increased risk of surgical site infection in posterior cervical operations.

OBJECTIVE: Surgical site infections (SSI) are a common post-operative complication, which increase cost, length of stay, and morbidity. Many risk factors have been, identified including body mass index (BMI). The purpose of this study was to evaluate, whether nuchal thickness rather than BMI increases risk for post-operative SSI in, posterior approach cervical spine operations. METHODS: A retrospective review of 180 patients who underwent posterior cervical spine, surgery at the University of Florida was performed. Nuchal thickness was measured, from the ventral most point of the spinous process of C5 to the skin on mid-sagittal preoperative, imaging. Diabetes status, BMI, smoking status, duration of anesthesia, prior, operations, and subcutaneous layer thickness was also collected. Infections were, identified according to the Centers for Disease Control (CDC) definitions for SSI. Univariate and multivariate analyses were performed by a biostatistician. RESULTS: Twenty patients (11%) had SSI. Smoking status, nuchal thickness of greater, than 55 mm or less than 29.8 mm, and subcutaneous fat thickness were all associated, with SSI. Age (OR 0.99, p = 0.45), diabetes (OR 0.50, p = 0.37), BMI (OR 1.03, p = 0.35), and use of intraoperative antibiotic powder (OR 0.62, p = 0.35) were not associated with, infection. On multivariate analysis (adjusted for smoking status), nuchal thickness, (p < 0.0001), subcutaneous fat thickness (p < 0.0001), and the ratio of subcutaneous fat to, nuchal thickness (p < 0.0001) all remained associated with SSI. CONCLUSIONS: Nuchal thickness and subcutaneous fat thickness are associated with SSI, in patients undergoing posterior cervical spine surgery. Risk of infection increases with very thin and very thick nuchal measurements.

The utility of routine post-hospitalization CT imaging in patients with non-operative mild to moderate traumatic brain injury.

Primary Objective: The purpose of this study was to determine the utility of CT imaging in patients with non-operative mild-moderate TBI with respect to changes in management.Methods: We conducted a retrospective analysis for 191 patients over a 5-year interval to examine whether follow-up CT initiated a change in management. We created a logistic regression model to incorporate different variables contributing to change in management.Results: Of 191 patients, 31 (16.2%) underwent a change in management. Change in management was associated with older age (65 yo vs. 55 yo, p = .011), diagnosis of subdural hematoma (p = .041), antiplatelet/anticoagulant therapy (p = .009), imaging performed (p = .16), and increased blood products on CT (p = <0.0001). For patients on antiplatelet/anticoagulant therapy, only those with worsening findings on CT required a change in management (p = .0002, 0.039). Surgical intervention was indicated in two patients.Conclusions: Limited clinical value exists in repeat CT scans for patients with mild TBI. Most patients with traumatic SAH, contusions, or asymptomatic patients should not have repeat imaging, as our study revealed only 2% of patients with positive CT finding and 0.6% requiring surgical intervention.

Patient-Reported Outcomes: Quality of Care on a Neurosurgical Ward.

BACKGROUND AND OBJECTIVES: Patient experience has become a quality measure in hospitals across the United States. To improve our understanding of our neurosurgical patient population's satisfaction needs, we undertook a detailed survey to identify areas of needed improvement. METHODS: Upon institutional review board approval, a detailed survey adopted from the Swedish quality-of-care patient questionnaire was distributed to all patients being discharged from the neurosurgical ward over a month period. From June 2014 to July 2014, all patients admitted to the neurosurgery service through the emergency department, clinic, or other facilities were enrolled. There were no specific inclusion criteria except for age older than 18 years, intact cognition to complete the survey, and return of a completed survey. Data were collected in 6 major categories, including information availability, patient accessibility, treatment received, caring perception, hospital environment, and overall satisfaction. Patients were evaluated by age, gender, surgery, and admission type. RESULTS: Our analysis demonstrated an improved overall satisfaction in those patients being admitted electively from the clinic as compared with emergency department admissions or hospital transfers. In addition, patients admitted on an emergent basis reported a lower satisfaction pertaining to receiving information, specifically test results. CONCLUSIONS: Emergent admissions represent a subpopulation that may require additional strategies to improve patient satisfaction survey scores.

Slow Dynamics of Acute Postoperative Pain Intensity Time Series Determined via Wavelet Analysis Are Associated With the Risk of Severe Postoperative Day 30 Pain.

BACKGROUND: Evidence suggests that increased early postoperative pain (POP) intensities are associated with increased pain in the weeks following surgery. However, it remains unclear which temporal aspects of this early POP relate to later pain experience. In this prospective cohort study, we used wavelet analysis of clinically captured POP intensity data on postoperative days 1 and 2 to characterize slow/fast dynamics of POP intensities and predict pain outcomes on postoperative day 30. METHODS: The study used clinical POP time series from the first 48 hours following surgery from 218 patients to predict their mean POP on postoperative day 30. We first used wavelet analysis to approximate the POP series and to represent the series at different time scales to characterize the early temporal profile of acute POP in the first 2 postoperative days. We then used the wavelet coefficients alongside demographic parameters as inputs to a neural network to predict the risk of severe pain 30 days after surgery. RESULTS: Slow dynamic approximation components, but not fast dynamic detailed components, were linked to pain intensity on postoperative day 30. Despite imbalanced outcome rates, using wavelet decomposition along with a neural network for classification, the model achieved an F score of 0.79 and area under the receiver operating characteristic curve of 0.74 on test-set data for classifying pain intensities on postoperative day 30. The wavelet-based approach outperformed logistic regression (F score of 0.31) and neural network (F score of 0.22) classifiers that were restricted to sociodemographic variables and linear trajectories of pain intensities. CONCLUSIONS: These findings identify latent mechanistic information within the temporal domain of clinically documented acute POP intensity ratings, which are accessible via wavelet analysis, and demonstrate that such temporal patterns inform pain outcomes at postoperative day 30.

Patient and Procedural Determinants of Postoperative Pain Trajectories.

BACKGROUND: The primary goal of this study was to evaluate patterns in acute postoperative pain in a mixed surgical patient cohort with the hypothesis that there would be heterogeneity in these patterns. METHODS: This study included 360 patients from a mixed surgical cohort whose pain was measured across postoperative days 1 through 7. Pain was characterized using the Brief Pain Inventory. Primary analysis used group-based trajectory modeling to estimate trajectories/patterns of postoperative pain. Secondary analysis examined associations between sociodemographic, clinical, and behavioral patient factors and pain trajectories. RESULTS: Five distinct postoperative pain trajectories were identified. Many patients (167 of 360, 46%) were in the moderate-to-high pain group, followed by the moderate-to-low (88 of 360, 24%), high (58 of 360, 17%), low (25 of 360, 7%), and decreasing (21 of 360, 6%) pain groups. Lower age (odds ratio, 0.94; 95% CI, 0.91 to 0.99), female sex (odds ratio, 6.5; 95% CI, 1.49 to 15.6), higher anxiety (odds ratio, 1.08; 95% CI, 1.01 to 1.14), and more pain behaviors (odds ratio, 1.10; 95% CI, 1.02 to 1.18) were related to increased likelihood of being in the high pain trajectory in multivariable analysis. Preoperative and intraoperative opioids were not associated with postoperative pain trajectories. Pain trajectory group was, however, associated with postoperative opioid use (P < 0.001), with the high pain group (249.5 oral morphine milligram equivalents) requiring four times more opioids than the low pain group (60.0 oral morphine milligram equivalents). CONCLUSIONS: There are multiple distinct acute postoperative pain intensity trajectories, with 63% of patients reporting stable and sustained high or moderate-to-high pain over the first 7 days after surgery. These postoperative pain trajectories were predominantly defined by patient factors and not surgical factors.

Facial Fractures: Independent Prediction of Neurosurgical Intervention.

CONTEXT: Over half of patients with facial fractures have associated traumatic brain injury (TBI). Based on force dynamic cadaveric studies, Lefort type 2 and 3 fractures are associated with severe injury. Correlation to neurosurgical intervention is not well characterized. AIMS: This study characterizes fracture pattern types in patients requiring neurosurgical intervention and assesses whether this is different from those not requiring intervention. SETTINGS AND DESIGN: Retrospective data were collected from the trauma registry from 2010 to 2019. SUBJECTS AND METHODS: Patients over 18, with confirmed facial fracture, reported TBI, available neuroimaging, and hospital admission were included. STATISTICAL ANALYSIS USED: Retrospective Contingency Analysis with Fraction of Total Comparison was used with Chi-square analysis for demographic and injury characteristic data. RESULTS: One thousand and one patients required no neurosurgical intervention and 171 required intervention. The intervention group had a significantly greater number of patients with Glasgow Coma Scale (GCS) <8 compared to the nonintervention group. Subset analysis revealed a twofold increase in Lefort type 2 fractures and notable increase in Lefort type 3 and panfacial fractures in the intervention group. Patients requiring craniectomy, craniotomy, or burr holes were much more likely to have Lefort type 2 or 3 fractures compared to those only requiring external ventricular drains or intracranial pressure monitoring. Subset analysis accounting for GCS supported these results. CONCLUSIONS: Lefort type 2 and type 3 fractures are significantly associated with requiring neurosurgical intervention. An improved algorithm for managing these patients has been proposed in the discussion. Ongoing work will focus on validating and refining the algorithm to improve patient care.

Predicting long-term postsurgical pain by examining the evolution of acute pain.

BACKGROUND: Increased acute postoperative pain intensity has been associated with the development of persistent postsurgical pain (PPP) in mechanistic and clinical investigations, but it remains unclear which aspects of acute pain explain this linkage. METHODS: We analysed clinical postoperative pain intensity assessments using symbolic aggregate approximations (SAX), a graphical way of representing changes between pain states from one patient evaluation to the next, to visualize and understand how pain intensity changes across sequential assessments are associated with the intensity of postoperative pain at 1 (M1) and 6 (M6) months after surgery. SAX-based acute pain transition patterns were compared using cosine similarity, which indicates the degree to which patterns mirror each other. RESULTS: This single-centre prospective cohort study included 364 subjects. Patterns of acute postoperative pain sequential transitions differed between the 'None' and 'Severe' outcomes at M1 (cosine similarity 0.44) and M6 (cosine similarity 0.49). Stratifications of M6 outcomes by preoperative pain intensity, sex, age group, surgery type and catastrophising showed significant heterogeneity of pain transition patterns within and across strata. Severe-to-severe acute pain transitions were common, but not exclusive, in patients with moderate or severe pain intensity at M6. CONCLUSIONS: Clinically, these results suggest that individual pain-state transitions, even within patient or procedural strata associated with PPP, may not alone offer good predictive information regarding PPP. Longitudinal observation in the immediate postoperative period and consideration of patient- and surgery-specific factors may help indicate which patients are at increased risk of PPP. SIGNIFICANCE: Symbolic aggregate approximations of clinically obtained, acute postoperative pain intraday time series identify different motifs in patients suffering moderate to severe pain 6 months after surgery.

A Comparison of the Existing Wellness Programs in Neurosurgery and Institution Champion's Perspectives.

Once the accepted norm during Harvey Cushing's time, the mantra of work to the exclusion of family and lifestyle is now recognized as deleterious to overall well-being. A number of neurosurgical residency training programs have implemented wellness programs to enhance the physical, mental, and emotional well-being of trainees and faculty. This manuscript highlights existing organized wellness education within neurosurgery residency programs in order to describe the motivations behind development, structure, and potential implementation strategies, cost of implementation, and identify successes and barriers in the integration process. This manuscript is designed to serve as a "how-to" guide for other programs who may identify a need in their own trainees and begins the discussion of how to develop wellness, leadership, grit, and resiliency within our future generation of neurosurgeons.

ACR Appropriateness Criteria® Hearing Loss and/or Vertigo.

This article presents guidelines for imaging utilization in patients presenting with hearing loss or vertigo, symptoms that sometimes occur concurrently due to proximity of receptors and neural pathways responsible for hearing and balance. These guidelines take into account the superiority of CT in providing bony details and better soft-tissue resolution offered by MRI. It should be noted that a dedicated temporal bone CT rather than a head CT best achieves delineation of disease in many of these patients. Similarly, optimal assessment often requires a dedicated high-resolution protocol designed to assess temporal bone and internal auditory canals even though such a study will be requested and billed as a brain MRI. Angiographic techniques are helpful in some patients, especially in the setting of vertigo. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

ACR Appropriateness Criteria® Orbits Vision and Visual Loss.

Visual loss can be the result of an abnormality anywhere along the visual pathway including the globe, optic nerve, optic chiasm, optic tract, thalamus, optic radiations or primary visual cortex. Appropriate imaging analysis of visual loss is facilitated by a compartmental approach that establishes a differential diagnosis on the basis of suspected lesion location and specific clinical features. CT and MRI are the primary imaging modalities used to evaluate patients with visual loss and are often complementary in evaluating these patients. One modality may be preferred over the other depending on the specific clinical scenario. Depending on the pattern of visual loss and differential diagnosis, imaging coverage may require targeted evaluation of the orbits and/or assessment of the brain. Contrast is preferred when masses and inflammatory processes are differential considerations. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Radiographic and Neurological Outcome After Surgical Treatment of Traumatic Fractures of the Ankylotic Thoracic Spine: A Retrospective Case Series.

BACKGROUND: Spontaneous thoracic ankylosis is a progressive degenerative process that predisposes patients to potentially highly unstable traumatic injuries. Acute hyperextension fractures result in dynamic instability putting the spinal cord at risk. OBJECTIVE: To describe preoperative radiographic characteristics of fractures of the ankylotic thoracic spine and relate findings to early postoperative radiographic and clinical outcomes. METHODS: A single center, retrospective review was performed of 28 surgically treated patients with fractures of the ankylotic thoracic spine. Radiographic assessment included preoperative fracture angulation (FA) and fracture displacement (FD), and postoperative change in sagittal alignment. Early clinical outcomes included preoperative and postoperative American Spinal Injury Association (ASIA) grade and perioperative complications. RESULTS: Seven patients (25%) presented with poor neurological grade (ASIA A-C) compared to 21 (75%) with good grade (ASIA D, E). At presentation, poor grade patients had a mean FA of 16.4° (range 0°-34.5°), and FD of 7.76 mm (range 0.8-9.2). Good grade patients had a mean FA of 18.2° (range 0°-43.3°), and FD of 4.77 mm (range 0-25.1). There was no statistically significant difference in FA or FD between groups (P = .70 and .20 respectively). All underwent posterior pedicle screw fixation for stabilization. Fifty per cent of patients presenting with ASIA C or D spinal cord injury improved 1 or more ASIA grades. There were no perioperative complications. Early postoperative sagittal alignment was maintained with a mean change of -2.6°. CONCLUSION: Presenting fracture alignment does not significantly correlate with pre- or postoperative neurological status. Early posterior stabilization preserved neurological function, with neurological recovery occurring in a portion of individuals.

External ventricular drain practice variations: results from a nationwide survey.

OBJECTIVE While guidelines exist for many neurosurgical procedures, external ventricular drain (EVD) insertion has yet to be standardized. The goal of this study was to survey the neurosurgical community and determine the most frequent EVD insertion practices. The hypothesis was that there would be no standard practices identified for EVD insertion or methods to avoid EVD-associated infections. METHODS The American Association of Neurological Surgeons membership database was queried for all eligible neurosurgeons. A 16-question, multiple-choice format survey was created and sent to 7217 recipients. The responses were collected electronically, and the descriptive results were tabulated. Data were analyzed using the chi-square test. RESULTS In total, 1143 respondents (15.8%) completed the survey, and 705 respondents (61.6%) reported tracking EVD infections at their institution. The most common self-reported infection rate ranged from 1% to 3% (56.1% of participants), and 19.7% of respondents reported a 0% infection rate. In total, 451 respondents (42.7%) indicated that their institution utilizes a formal protocol for EVD placement. If a respondent's institution had a protocol, only 258 respondents (36.1%) always complied with the protocol. Protocol utilization for EVD insertion was significantly more frequent among residents, in academic/hybrid centers, in ICU settings, and if the institution tracked EVD-associated infection rates (p < 0.05). A self-reported 0% infection rate was significantly more commonly associated with a higher level of training (e.g., attending physicians), private center settings, a clinician performing 6 to 10 EVD insertions within the previous 12 months, and prophylactic continuous antibiotic utilization (p < 0.05). CONCLUSIONS This survey demonstrated heterogeneity in the practices for EVD insertion. No standard practices have been proposed or adopted by the neurosurgical community for EVD insertion or complication avoidance. These results highlight the need for the nationwide standardization of technique and complication prevention measures.
