RESUMO

Errors in communication are a major source of preventable medical errors. Neurosurgical patients frequently present to the neuro-intensive care unit (NICU) postoperatively, where handoffs occur to coordinate care within a large multidisciplinary team. A multidisciplinary working group at our institution started an initiative to improve postoperative neurosurgical handoffs using validated quality improvement methodology. Baseline handoff practices were evaluated through staff surveys and serial observations. A formalized handoff protocol was implemented using the evidence based IPASS format (Illness severity, Patient summary, Action list, Situational awareness and contingency planning, Synthesis by receiver). Cycles of objective observations and surveys were employed to track practice improvements and guide iterative process changes over one year. Surveys demonstrated improved perceptions of handoffs as organized (17.1% vs 69.7%, p < 0.001), efficient (27.0% vs. 72.7%, p < 0.001), comprehensive (17.1% vs. 66.7%, p < 0.001), and safe (18.0% vs. 66.7%, p < 0.001), noting improved teamwork (31.5% vs. 69.7%, p < 0.001). Direct observations demonstrated improved communication of airway concerns (47.1% observed vs. 92.3% observed, p < 0.001), hemodynamic concerns (70.6% vs. 97.1%, p = 0.001), intraoperative events (52.9% vs. 100%, p < 0.001), neurological examination (76.5% vs. 100%, p < 0.001), vital sign goals (70.6% vs. 100%, p < 0.001), and required postoperative studies (76.5% vs. 100%, p < 0.001). Receiving teams demonstrating improved rates of summarization (47.1% vs. 94.2%, p = 0.005) and asking questions (76.5% vs 98.1%, p = 0.004). The mean handoff time during long-term follow-up was 4.4 min (95% confidence interval = 3.9-5.0 min). Standardization of handoff practices yields improvements in communication practices for postoperative neurosurgical patients.

RESUMO

BACKGROUND: There is a paucity of information regarding treatment strategies and variables affecting outcomes of revision lumbar fusions. OBJECTIVE: To evaluate the influence of primary vs different surgeon on functional outcomes of revisions. METHODS: All elective lumbar fusion revisions, March 2018 to August 2019, were retrospectively categorized as performed by the same or different surgeon who performed the primary surgery. Oswestry Disability Index (ODI) and clinical variables were collected. Multiple logistic regression identified multivariable-adjusted odds ratio (OR) of independent variables analyzed. RESULTS: Of the 130 cases, 117 (90%) had complete data. There was a slight difference in age in the same (median: 59; interquartile range [IQR], 54-66) and different surgeon (median: 67; IQR, 56-72) groups (P = .02); all other demographic variables were not significantly different (P > .05). Revision surgery with a different surgeon had an ODI improvement (median: 8; IQR, 2-14) greater than revisions performed by the same surgeon (median: 1.5; IQR, -3 to 10) (P < .01). Revisions who achieved minimum clinically important difference (MCID) performed by different surgeon (59.7%) were also significantly greater than the ones performed by the same surgeon (40%) (P = .042). Multivariate analysis demonstrated that a different surgeon revising (OR, 2.37; [CI]: 1.007-5.575, P = .04) was an independent predictor of MCID achievement, each additional 2 years beyond the last surgery conferred a 2.38 ([CI]: 1.36-4.14, P < .01) times greater odds of MCID achievement, and the anterior lumbar interbody fusion approach decreased the chance of achieving MCID (OR, 0.19; [CI]: 0.04-0.861, P = .03). CONCLUSION: All revision lumbar spinal fusion approaches may not achieve the same outcomes. This analysis suggests that revision surgeries may have better outcomes when performed by a different surgeon.

RESUMO

OBJECTIVE: The authors compared primary lumbar spine fusions with revision fusions by using patient Oswestry Disability Index (ODI) scores to evaluate the impact of the North American Spine Society (NASS) evidence-based medicine (EBM) lumbar fusion indications on patient-reported outcome measures of revision surgeries. METHODS: This study was a retrospective analysis of a prospective observational cohort of patients who underwent elective lumbar fusion between January 2018 and December 2019 at a single quaternary spine surgery service and had a minimum of 6 months of follow-up. A prospective quality improvement database was constructed that included the data from all elective lumbar spine surgeries, which were categorized prospectively as primary or revision surgeries and EBM-concordant or EBM-discordant revision surgeries based on the NASS coverage EBM policy. In total, 309 patients who met the inclusion criteria were included in the study. The ODIs of all groups (primary, revision, revision EBM concordant, and revision EBM discordant) were statistically compared. Differences in frequencies between cohorts were evaluated using chi-square and Fisher's exact tests. The unpaired 2-tailed Student t-test and the Mann-Whitney U-test for nonparametric data were used to compare continuous variables. Logistic regression was performed to determine the associations between independent variables (surgery status and NASS criteria indications) and functional outcomes. RESULTS: Primary lumbar fusions were significantly associated with improved functional outcomes compared with revisions, as evidenced by ODI scores (OR 1.85, 95% CI 1.16-2.95 to achieve a minimal clinically important difference, p = 0.01). The percentage of patients whose functional status had declined at the 6-month postoperative evaluation was significantly higher in patients who had undergone a revision surgery than in those who underwent a primary surgery (23% vs 12.3%, respectively). An increase in ODI score, indicating worse clinical outcome after surgery, was greater in patients who underwent revision procedures (OR 2.14, 95% CI 1.17-3.91, p = 0.0014). Patients who underwent EBM-concordant revision surgery had significantly improved mean ODI scores compared with those who underwent EBM-discordant revision surgery (7.02 ± 5.57 vs -4.6 ± 6.54, p < 0.01). CONCLUSIONS: The results of this prospective quality improvement program investigation illustrate that outcomes of primary lumbar fusions were superior to outcomes of revisions. However, revision procedures that met EBM guidelines were associated with greater improvements in ODI scores, which indicates that the use of defined EBM guideline criteria for reoperation can improve clinical outcomes of revision lumbar fusions.

RESUMO

BACKGROUND: Instrumented fusion procedures are essential in the treatment of degenerative lumbar spine disease to alleviate pain and improve neurological function, but they are being performed with increasing incidence and variability. We implemented a training module for neurosurgery residents that is based on evidence-based criteria for lumbar fusion surgery and measured its effectiveness in residents' decision making regarding whether patients should or should not undergo instrumented fusion. METHODS: The study design was a pretest versus posttest experiment conducted from September 2019 until July 2020 to measure improvement after formalized instruction on evidence-based guidelines. Neurosurgery residents of all training levels at our institution participated. A test was administered at the beginning of each academic year. The highest possible score was 18 points in each pretest and posttest. RESULTS: There was a general trend of test score improvement across all levels of training with a greater degree of change for participants with lower compared with higher pretest scores, indicating a possible ceiling effect. Paired t test demonstrated an overall mean score increase of 2 points (P < 0.0001), equivalent to an 11.11% increase (P < 0.0001). Stratified by training group, mean absolute change in test score was 2 (P = 0.0217), 1.67 (P = 0.0108), and 2.25 (P = 0.0173) points for junior, midlevel, and senior training groups, respectively. CONCLUSIONS: Incorporating a targeted evidence-based learning module for lumbar spine fusion surgery can improve neurosurgery residents' clinical decision making toward a more uniform practice supported by published data.

RESUMO

BACKGROUND: Idiopathic spinal cord herniation (ISCH) is a rare pathology characterized by extravasation of the spinal cord through a dural defect. The optimal algorithm for choosing operative or nonoperative management is not well elucidated, partially because of the rarity of this pathology. We present the largest single-center series of ISCH and compare operative treatment to conservative management. METHODS: A retrospective case series of all patients evaluated for treatment of ISCH at our institution between 2010 and 2019 was conducted. Demographic variables, presenting symptoms, and imaging characteristics were assessed for all patients. For patients who underwent operative treatment, surgical approach, postoperative course, and discharge outcomes were recorded. Follow-up notes were reviewed for status of symptoms and functional capabilities, which were synthesized into Odom's criteria score. RESULTS: Sixteen patients met the inclusion criteria for this study, 8 of whom underwent operative treatment. No significant differences were found between operative and nonoperative groups with regard to demographic variables or pathology characteristics. Odom's criteria scores for the operative cohort were 12.5% (1 of 8) Excellent, 62.5% (5 of 8) Good, 12.5% (1 of 8) Fair, and 12.5% (1 of 8) Poor. Odom's criteria scores for the nonoperative cohort were 16.7% (1 of 6) Excellent, 33.3% (2 of 6) Good, 16.7% (1 of 6) Fair, and 33.3% (2 of 6) Poor. There was no significant difference between Odom's criteria score distribution between the operative and nonoperative groups at latest follow up (P = 0.715). CONCLUSIONS: Conservative management of spinal cord herniation is an option that does not preclude symptomatic improvement in patients with idiopathic spinal cord herniation.

RESUMO

INTRODUCTION: Cervical spontaneous epidural hematoma is a serious neurosurgical pathology that often requires prompt surgical intervention. While a variety of causes may contribute, the authors present the first case in the literature of cervical disc extrusion provoking epidural hemorrhage and acute neurological deterioration. CASE PRESENTATION: A 65 year old male presented with six months of worsening signs and symptoms of cervical myelopathy. He had progressive deterioration over the course of two weeks leading to ambulatory dysfunction requiring a cane for assistance. While undergoing his medical workup in the emergency department, the patient became acutely plegic in the right lower extremity prompting emergent surgical decompression and stabilization. DISCUSSION: Based on imaging, pathology, and intraoperative findings, it was concluded that the patient had an extruded disc segment that may have precipitated venous bleeding in the epidural space and findings of acute cervical cord compression. Cervical disc extrusion may lead to venous damage, epidural hematoma, and spinal cord compression. If this unique presentation is recognized and addressed in a timely manner, patient outcomes may still be largely positive as this case demonstrates.

RESUMO

Background: Coronavirus disease 2019 (COVID-19) mortality has waned significantly over time; however, factors contributing towards this reduction largely remain unidentified. The purpose of this study was to evaluate the trend in mortality at our large tertiary academic health system and factors contributing to this trend. Methods: This is a retrospective cohort study of intensive care unit (ICU) patients diagnosed with COVID-19 between March and August 2020 admitted across 14 hospitals in the Philadelphia area. Collected data included demographics, comorbidities, admission risk of mortality score, laboratory values, medical interventions, survival outcomes, hospital and ICU length of stay (LOS) and discharge disposition. Chi-square (χ2) test, Fisher exact test, Cochran-Mantel-Haenszel method, multinomial logistic regression models, independent sample t-test, Mann-Whitney U test and one-way analysis of variance (ANOVA) were used. Results: A total of 1,204 patients were included. Overall mortality was 39%. Mortality declined significantly from 46% in March to 14% in August 2020 (P < 0.05). The most common underlying comorbidities were hypertension (60.2%), diabetes mellitus (44.7%), dyslipidemia (31.6%) and congestive heart failure (14.7%). Hydroxychloroquine (HCQ) use was more commonly associated with the patients who died, while the use of remdesivir, tocilizumab, steroids and duration of these medications were not significantly different. Peak values of ferritin, lactate dehydrogenase (LDH), C-reactive protein (CRP) and D-dimer levels were significantly higher in patients who died (P < 0.05). The mean hospital LOS was significantly longer in the patients who survived compared to the patients who died (18 vs. 12, P < 0.05). Conclusions: The mortality of patients admitted to our ICU system significantly decreased over time. Factors that may have contributed to this may be the result of a better understanding of COVID-19 pathophysiology and treatments. Further research is needed to elucidate the factors contributing to a reduction in the mortality rate for this patient population.

RESUMO

BACKGROUND: United States (U.S.) healthcare is a volume-based inefficient delivery system. Value requires the consideration of quality, which is lacking in most healthcare disciplines. OBJECTIVE: To assess whether patients who met specific evidence-based medicine (EBM)-based criteria preoperatively for lumbar fusion would achieve higher rates of achieving the minimal clinical important difference (MCID) than those who did not meet the EBM indications. METHODS: All elective lumbar fusion cases, March 2018 to August 2019, were prospectively evaluated and categorized based on EBM guidelines for surgical indications. The MCID was defined as a reduction of ≥5 points in Oswestry Disability Index (ODI). Multiple logistic regression identified multivariable-adjusted odds ratio of EBM concordance. RESULTS: A total of 325 lumbar fusion patients were entered with 6-mo follow-up data available for 309 patients (95%). The median preoperative ODI score was 24.4 with median 6-mo improvement of 7.0 points (P < .0001). Based on ODI scores, 79.6% (246/309) improved, 3.8% (12/309) had no change, and 16% (51/309) worsened. A total of 191 patients had ODI improvement reaching the MCID. 93.2% (288/309) cases were EBM concordant, while 6.7% (21/309) were not.In multivariate analysis, EBM concordance (P = .0338), lower preoperative ODI (P < .001), lower ASA (American Society of Anesthesiologists) (P = .0056), and primary surgeries (P = .0004) were significantly associated with improved functional outcome. EBM concordance conferred a 3.04 (95% CI 1.10-8.40) times greater odds of achieving MCID in ODI at 6 mo (P = .0322), adjusting for other factors. CONCLUSION: This analysis provides validation of EBM guideline criteria to establish optimal patient outcomes. The EBM concordant patients had a greater than 3 times improved outcome compared to those not meeting EBM fusion criteria.

RESUMO

Intensive care units (ICUs) lack both standardized performance indicators to better understand the effectiveness of interventions and uniform platforms to present these indicators. The goal of this study was to identify ICU metrics meaningful to stakeholders to help guide the development of a local visualization dashboard. Individual ICU directors were interviewed to collate their input on metrics important to their units. These qualitative data were used to develop a dashboard draft, after which the authors surveyed 20 stakeholders from different hospital departments for feedback on its content and structure. The varied survey results reinforced the inherent difficulties of adapting previously developed measurement tools while also selecting ICU performance measures that are simultaneously widely accepted yet relevant to local practice. These results also call attention to the importance of interdisciplinary input in quality dashboard development, thereby enabling more successful implementation and utilization for ICU quality improvement.

RESUMO

IMPORTANCE: Pneumonia due to COVID-19 can lead to respiratory failure and death due to the development of the acute respiratory distress syndrome. Tocilizumab, a monoclonal antibody targeting the interleukin-6 receptor, is being administered off-label to some patients with COVID-19, and although early small studies suggested a benefit, there are no conclusive data proving its usefulness. OBJECTIVE: To evaluate outcomes in hospitalized patients with COVID-19 with or without treatment with Tocilizumab. DESIGN, SETTING, PARTICIPANTS: Retrospective study of 1938 patients with confirmed COVID-19 pneumonia admitted to hospitals within the Jefferson Health system in Philadelphia, Pennsylvania, between March 25, 2020 and June 17, 2020, of which 307 received Tocilizumab. EXPOSURES: Confirmed COVID-19 pneumonia. MAIN OUTCOMES AND MEASURES: Outcomes data related to length of stay, admission to intensive care unit (ICU), requirement of mechanical ventilation, and mortality were collected and analyzed. RESULTS: The average age was 65.2, with 47% women; 36.4% were African-American. The average length of stay was 22 days with 26.3% of patients requiring admission to the ICU and 14.9% requiring mechanical ventilation. The overall mortality was 15.3%. Older age, admission to an ICU, and requirement for mechanical ventilation were associated with higher mortality. Treatment with Tocilizumab was also associated with higher mortality, which was mainly observed in subjects not requiring care in an ICU with estimated odds ratio (OR) of 2.9 (p = 0.0004). Tocilizumab treatment was also associated with higher likelihood of admission to an ICU (OR = 4.8, p < 0.0001), progression to requiring mechanical ventilation (OR = 6.6, p < 0.0001), and increased length of stay (OR = 16.2, p < 0.0001). CONCLUSION AND RELEVANCE: Our retrospective analysis revealed an association between Tocilizumab administration and increased mortality, ICU admission, mechanical ventilation, and length of stay in subjects with COVID-19. Prospective trials are needed to evaluate the true effect of Tocilizumab in this condition.

RESUMO

STUDY DESIGN: Retrospective observational case series. OBJECTIVE: To assess the outcome of patients with diffuse idiopathic skeletal hyperostosis (DISH) with dysphagia who underwent cricopharyngeal myotomy (CPM) in conjunction with anterior osteophytectomy (OP). METHODS: This is a retrospective observational study of 9 patients that received combined intervention by neurosurgeons and otolaryngologists. Inclusion criteria for surgery consisted of patients who failed to respond to conservative treatments for dysphagia and had evidence of both upper esophageal dysfunction and osteophyte compression. We present the largest series in literature to date including patients undergoing combined OP and CPM. RESULTS: A total of 88.9% (8/9) of the patients who underwent OP and CPM showed improvement in their symptoms. Of the aforementioned group, 22.2% of these patients had complete resolution of their symptoms, 11.1% did not improve, and only 2 patients showed recurrence of their symptoms. None of the patients in whom surgery was performed required reoperation or suffered serious complication related to the surgical procedures. CONCLUSION: Based on the literature results, high rate of improvements in dysphagia, and low rate of complications, combined OP and CPM procedures may be beneficial to a carefully selected group of patients.

RESUMO

Herein, the authors present the case of a 54-year-old male diagnosed with coronavirus disease 2019 (COVID-19) during a screening test. The patient was asked to self-isolate at home and report with any exacerbations of symptoms. He presented later with pneumonia complicated by encephalopathy at days 14 and 15 from initial diagnosis, respectively. MRI of the brain showed bithalamic and gangliocapsular FLAIR signal abnormality with mild right-sided thalamic and periventricular diffusion restriction. A CT venogram was obtained given the distribution of edema and demonstrated deep venous thrombosis involving the bilateral internal cerebral veins and the vein of Galen. CSF workup was negative for encephalitis, as the COVID-19 polymerase chain reaction (PCR) test and bacterial cultures were negative. A complete hypercoagulable workup was negative, and the venous thrombosis was attributed to a hypercoagulable state induced by COVID-19. The mental decline was attributed to bithalamic and gangliocapsular venous infarction secondary to deep venous thrombosis. Unfortunately, the patient's condition continued to decline, and care was withdrawn.

RESUMO

The utilization of robotics has been gaining increased popularity in spine surgery. It can be used to assist in pedicle screw insertion when anatomy is complex in deformity surgery, but is also helpful in degenerative spine as it can minimize tissue dissection and fluoroscopy use.1-6 We present an operative video that demonstrates the use of a robotic system (Globus Excelsius GPS, Audubon, Pennsylvania) for thoracic instrumentation in an unstable fracture. The patient we present is a 64-yr-old male who sustained a T8-9 distraction extension fracture after falling down a flight of stairs. His computed tomography (CT) scan showed ossification of the anterior longitudinal ligament making ankylosing spondylitis the likely underlying condition.7,8 His magnetic resonance imaging showed an epidural hematoma extending from T7 to T11. Due to the unstable nature of this fracture and the presence of the hematoma, informed consent was obtained and the patient underwent thoracic pedicle screw fixation from T7 to T11 and laminectomy for hematoma evacuation. A preoperative CT was done for screw trajectory planning. Paraspinal muscle dissection was limited to the hematoma level to allow for laminectomy and evacuation. After registration of the patient to the robotic system using C-arm fluoroscopy, pilot burr holes are drilled using a rigid robotic arm and with optical tracking in real time. This reduces the degrees of freedom and allows for higher precision of screw placement. To the authors' knowledge, this video is the first one to show the utilization of robotics for thoracic instrumentation in an acute fracture.

RESUMO

BACKGROUND: Decompressive hemicraniectomy (DHC) is well established as an effective life-saving intervention. Although literature documents a correlation between mortality and hemicraniectomy flap size, no literature exists demonstrating whether a larger flap may be achieved with 3-pin fixation devices versus nonfixed positioning (e.g., occipital headrest, gel donut). Therefore, positioning for DHC remains the preference of the institution and attending physician. METHODS: Patients undergoing DHC during 2005-2016 were identified using Current Procedural Terminology codes. Inclusion criteria were: operative note available in the electronic medical record and postoperative head computed tomography (hCT). Exclusion criteria were: age <18 years, missing data in electronic medical record, no postoperative hCT performed, and craniectomy not done with intention of performing a hemicraniectomy (i.e., craniotomy converted to craniectomy). Anteroposterior diameter of the hemicraniectomy flap was measured in millimeters on the postoperative hCT. The average diameter was compared between the fixed positioning and nonfixed positioning groups. RESULTS: Analysis included 522 patients who met inclusion criteria; 363 were in the fixed positioning group, and 159 were in the nonfixed positioning group. The average hemicraniectomy diameter was 132.17 mm in the fixed positioning group, and 129.74 mm in the nonfixed positioning group, which was statistically significant (P = 0.027). CONCLUSIONS: This is the first large-scale single-institution study evaluating whether operative positioning for DHC affects the size of a hemicraniectomy flap. Positioning in 3-point fixation led to a statistically significant larger average diameter compared with nonfixed positioning. This indicates that the risks associated with pin fixation as well as additional time spent in positioning in this fashion are offset by the ability to obtain a larger hemicraniectomy flap, which is associated with decreased mortality.

RESUMO

BACKGROUND: Anterior cervical spine surgeries have low morbidity, sufficient surgical corridor, and quick recovery times. Although largely considered a safe and effective procedure to address cervical myelopathy, radiculopathy, and deformity, dysphagia is a frequent yet poorly understood adverse event. One treatment is cricopharyngeal myotomy (CPM), which aids in swallowing for patients with refractory issues after anterior cervical decompression and fusion (ACDF). CASE DESCRIPTION: Here we describe our experience with 6 patients requiring revision ACDF with preoperative dysphagia who were treated with concurrent revision and CPM. Our series demonstrated that CPM is an effective and safe procedure used in combination with an ACDF. In our series, we had 6 patients with dysphagia preoperatively who were all able to undergo ACDF without worsening of their dysphagia despite having risk factors predisposing them to this complication. In our series, 83% of patients either improved or experienced resolution of their symptoms with only 1 patient failing to improve. CONCLUSIONS: Given its efficacy and safety, patients planned for ACDF with preoperative dysphagia should be evaluated by ENT for potential CPM.

RESUMO

BACKGROUND: Severe traumatic brain injury (TBI) remains a major cause of morbidity and mortality with mortality rates reaching 35%. Intracranial pressure (ICP) monitoring is used to prevent secondary brain injury and death. However, while the association of elevated ICP and worsened outcomes is accepted, routine ICP monitoring has been questioned after the publication of several studies including the Benchmark Evidence from South American Trials: Treatment of Intracranial Pressure trial. We examined whether severe TBI patients in the trauma system of Pennsylvania fared better with or without ICP monitoring. METHODS: We conducted a statewide retrospective analysis and included all TBI patients >18 years with an admission Glasgow Coma Scale (GCS) <9 from January 2000 through December 2017. The primary outcome was mortality. Secondary outcomes examined were intensive care unit length of stay (LOS) and discharge functional independence measure (FIM). RESULTS: A total of 36,929 patients matched our inclusion criteria and were included in the analysis. Of those, 6025 (16.3%) had ICP monitor placement. Mean ICU LOS was significantly higher in ICP-monitored patients (13.1 ± 11.6 days vs. 6.0 ± 10.8 days, P < 0.0001). Increasing age was a significant predictor of death (P < 0.0001). Mean FIM scores at discharge were significantly higher in patients without an ICP monitor (16.21 ± 4.91 vs. 9.53 ± 5.07, P < 0.0001). When controlling for injury severity score, GCS, age, and craniotomy, ICP monitoring conferred a hazard ratio of 0.85 (χ2 = 32.63, P < 0.0001), a 25% reduction of in-hospital mortality compared with non-ICP-monitored patients. CONCLUSION: We found that ICP-monitored patients had a lower risk of in-hospital mortality. Our findings support the use of ICP monitors in eligible patients.

RESUMO

BACKGROUND: Traumatic brain injury (TBI) carries a devastatingly high rate of morbidity and mortality. OBJECTIVE: To assess whether patients undergoing craniotomy/craniectomy for severe TBI fare better at level I than level II trauma centers in a mature trauma system. METHODS: The data were extracted from the Pennsylvania Trauma Outcome Study database. Inclusion criteria were patients > 18 yr with severe TBI (Glasgow Coma Scale [GCS] score less than 9) undergoing craniotomy or craniectomy in the state of Pennsylvania from January 1, 2002 through September 30, 2017. RESULTS: Of 3980 patients, 2568 (64.5%) were treated at level I trauma centers and 1412 (35.5%) at level II centers. Baseline characteristics were similar between the 2 groups except for significantly worse GCS scores at admission in level I centers (P = .002). The rate of in-hospital mortality was 37.6% in level I centers vs 40.4% in level II centers (P = .08). Mean Functional Independence Measure (FIM) scores at discharge were significantly higher in level I (10.9 ± 5.5) than level II centers (9.8 ± 5.3; P < .005). In multivariate analysis, treatment at level II trauma centers was significantly associated with in-hospital mortality (odds ratio, 1.2; 95% confidence interval, 1.03-1.37; P = .01) and worse FIM scores (odds ratio, 1.4; 95% confidence interval, 1.1-1.7; P = .001). Mean hospital and ICU length of stay were significantly longer in level I centers (P < .005). CONCLUSION: This study showed superior functional outcomes and lower mortality rates in patients undergoing a neurosurgical procedure for severe TBI in level I trauma centers.

RESUMO

OBJECTIVE: Intracranial pressure (ICP)-guided therapy has been the mainstay of treatment of patients with severe traumatic brain injury (TBI), but recent data have questioned its efficacy. The aim of this study was to demonstrate trends in compliance to TBI guidelines and use of ICP-guided care in a mature trauma system. METHODS: A retrospective analysis was conducted of 36,915 patients with severe TBI collected by the Pennsylvania Trauma Systems Foundation. The registry includes all patients >18 years old with a diagnosis of TBI with a Glasgow Coma Scale score ≤8 who were admitted from January 2000 to December 2017. RESULTS: Of 36,915 patients, 73.6% were men with a median age of 43.0 ± 21.3 years. An ICP monitor was placed in 16.3% of all patients. The rate of ICP monitoring ranged from 17.8% of patients in 2000-2004 to 16.7% in 2005-2009, 16.4% in 2010-2014, and 12.8% in 2015-2017 (P < 0.001). The most statistically significant decrease was noted from 2014 (16.4%) to 2015 (14.1%, P = 0.042). The percent decrease in ICP monitoring from 2000-2014 to 2015-2017 was equivalent for patients with Glasgow Coma Scale scores of 3-5 (-4.0%) and 6-8 (-4.5%). CONCLUSIONS: As studies emerged that demonstrated unclear benefit of ICP monitoring in improving care in patients with severe TBI, there was a significant statewide decline in the use of ICP monitoring after 2014 among all TBI subpopulations despite noteworthy limitations in the aforementioned studies and clear recommendations from the Brain Trauma Foundation guidelines.

RESUMO

Study Design: Systematic analysis and review. Objective: Evaluation of the presentation, etiology, management strategies (including both surgical and nonsurgical options), and neurological functional outcomes in patients with cervical spinal epidural abscess (SEA). Methods: The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria were used to create a framework based on which articles pertaining to cervical SEA were chosen for review following a search of the Ovid and PubMed databases using the search terms "epidural abscess" and "cervical." Included studies needed to have at least 4 patients aged 18 years or older, and to have been published within the past 20 years. Results: Database searches yielded 521 potential articles in PubMed and 974 potential articles in Ovid. After review, 11 studies were ultimately identified for inclusion in this systematic review. Surgery appears to be a well-tolerated management strategy with limited complications for patients with cervical SEA. However, the quantity of data comparing medical and surgical treatment of cervical SEA is limited and the bulk of the data is derived from low quality studies. Conclusion: Data reporting was heterogeneous among studies making it difficult to draw discrete conclusions. Early surgical intervention may be appropriate in selected patients with cervical epidural abscess, but it is not clear what distinguishes these patients from those who are successfully managed nonoperatively.
