Defining the cervical spine clearance algorithm: A single-institution prospective study of more than 9,000 patients.

BACKGROUND: Variability exists in the approach to cervical spine (c-spine) clearance after significant trauma. Using concurrently gathered data on more than 9,000 such patients, the current study develops an evidence-based and readily adoptable algorithm for c-spine clearance aimed at timely removal of collar, optimal use of imaging, and appropriate spine consultations. METHODS: Prospective study of adult blunt trauma team alert (TTA) patients presenting at a Level I trauma center who underwent screening computed tomography (CT) to diagnose/rule out c-spine injury (January 2008 to May 2014). Regression analysis comparing patients with and without c-spine injury-fracture and/or ligament-was used to identify significant predictors of injury. The predictors with the highest odds ratio were used to develop the algorithm. RESULTS: Among 9,227 patients meeting inclusion criteria, c-spine injury was identified in 553 patients (5.99%). All 553 patients had a c-spine fracture, and of these, 57 patients (0.6% of entire population and 10.31% of patients with injury) also had a ligamentous injury. No patient with a normal CT result was found to have an injury. The five greatest predictors of ligament injury that follow were used to develop the algorithm: (1) CT evidence of ligament injury; (2) fracture pattern "not" isolated transverse/spinous process; (3) neurologic symptoms; (4) midline tenderness; and (5) Glasgow Coma Scale score <15. CONCLUSION: TTA patients should undergo screening c-spine CT to rule out injury. Most patients will have a negative CT and can have their collars removed. A select group of patients will require collars and spine consultation and a smaller subset of magnetic resonance imaging to rule out ligament injury.

An evidence-based approach to patient selection for emergency department thoracotomy: A practice management guideline from the Eastern Association for the Surgery of Trauma.

BACKGROUND: Within the GRADE (Grading of Recommendations Assessment, Development and Evaluation) framework, we performed a systematic review and developed evidence-based recommendations to answer the following PICO (Population, Intervention, Comparator, Outcomes) question: should patients who present pulseless after critical injuries (with and without signs of life after penetrating thoracic, extrathoracic, or blunt injuries) undergo emergency department thoracotomy (EDT) (vs. resuscitation without EDT) to improve survival and neurologically intact survival? METHODS: All patients who underwent EDT were included while those involving either prehospital resuscitative thoracotomy or operating room thoracotomy were excluded. Quantitative synthesis via meta-analysis was not possible because no comparison or control group (i.e., survival or neurologically intact survival data for similar patients who did not undergo EDT) was available for the PICO questions of interest. RESULTS: The 72 included studies provided 10,238 patients who underwent EDT. Patients presenting pulseless after penetrating thoracic injury had the most favorable EDT outcomes both with (survival, 182 [21.3%] of 853; neurologically intact survival, 53 [11.7%] of 454) and without (survival, 76 [8.3%] of 920; neurologically intact survival, 25 [3.9%] of 641) signs of life. In patients presenting pulseless after penetrating extrathoracic injury, EDT outcomes were more favorable with signs of life (survival, 25 [15.6%] of 160; neurologically intact survival, 14 [16.5%] of 85) than without (survival, 4 [2.9%] of 139; neurologically intact survival, 3 [5.0%] of 60). Outcomes after EDT in pulseless blunt injury patients were limited with signs of life (survival, 21 [4.6%] of 454; neurologically intact survival, 7 [2.4%] of 298) and dismal without signs of life (survival, 7 [0.7%] of 995; neurologically intact survival, 1 [0.1%] of 825). CONCLUSION: We strongly recommend that patients who present pulseless with signs of life after penetrating thoracic injury undergo EDT. We conditionally recommend EDT for patients who present pulseless and have absent signs of life after penetrating thoracic injury, present or absent signs of life after penetrating extrathoracic injury, or present signs of life after blunt injury. Lastly, we conditionally recommend against EDT for pulseless patients without signs of life after blunt injury. LEVEL OF EVIDENCE: Systematic review/guideline, level III.

The burden of the U.S. crisis in the surgical critical care workforce and workflow.

There will be a 46 per cent shortage of intensivists by 2030. Currently, only 3 per cent of U.S. critical care is provided by surgeon-intensivists. Measurement of the current workload is needed to understand the ramifications of the expected shortage of surgeon-intensivists. The purpose of this study is to evaluate the self-reported workload of U.S. surgeon-intensivists. Over a 2-month period, a voluntary and anonymous survey of the surgery section of the Society of Critical Care Medicine was performed using Survey Monkey. Only surgeons were invited to participate. We assessed personnel resources and surgeon-intensivists workload in the intensive care unit (ICU) and on their postcall day. Two hundred sixty-two persons responded. Sixty-nine per cent had administrative responsibilities and 42 per cent covered bed allocation/transfer center duties while in the ICU. Seventy-six per cent covered trauma and general surgery call and 72 per cent covered the outpatient clinic or had elective surgery cases while responsible for the ICU. Only 14 per cent had no other responsibilities. Twenty-one per cent did not round with residents and 50 per cent did not round with a fellow. Thirty-six per cent did not work with advanced practitioners. The majority of surgeon-intensivists have significant responsibilities in addition to providing ICU care. This workload should be factored into the expected shortage of surgical intensivists relative to the expected increase in critical care demand.

Open extremity fractures: impact of delay in operative debridement and irrigation.

BACKGROUND: Early (<8 hours) operative debridement and irrigation (D&I) of open fractures are considered essential to reduce the risk of deep infection. With the advent of powerful antimicrobials, this axiom has been challenged. The current study evaluates the rates of deep infections of open fractures in relation to the time to the first D&I. METHODS: A list of all blunt open fractures during a 6-year period was obtained from the trauma registry. Patients were evaluated for age, Injury Severity Score (ISS), physiologic derangement (systolic blood pressure, lactate, Revised Trauma Score [RTS]), and fracture type (Gustilo). Time to the first D&I was calculated. All patients received appropriate prophylactic antimicrobials. Infection rates were calculated and correlated to the time to the first D&I (<8 hours vs. >8 hours). Regression analysis was performed to identify independent predictors of infection. RESULTS: During the 72-month study period, 404 patients met entry criteria, with 415 open extremity fractures (upper, 129; lower, 287). Early (<8 hours) and delayed (>8 hours) groups were well matched, although the age was lower and ISS was higher in the group with greater than 8 hours. The rates of infection were 35 (11%) of 328 (<8 hour) and 17 (19%) of 87 (>8 hours) (p < 0.05). When fractures were subgrouped by extremity, for the lower extremity, both a delay of greater than 8 hours and higher Gustilo type correlated with the development of infection. In the upper extremity, only higher Gustilo type correlated, and a delay to the first D&I did not increase the incidence of infection. Regression analysis revealed that higher ISS (odd ratio [OR], 1.052; 95% confidence interval [CI], 1.019-1.086), Gustilo grade, and a delay of greater than 8 hours (OR, 2.035; 95% CI, 1.022-4.054) were independent predictors of infection for the all-extremity model. Separate models for upper and lower extremities showed that the same three parameters were independent predictors for the lower extremity (ISS: OR, 1.045; 95% CI, 1.004-1.087; Gustilo type and >8-hour delay: OR, 3.006; 95% CI, 1.280-7.059), but none for the upper extremity. CONCLUSION: Delay of greater than 8 hours to the first D&I for open fractures of the lower extremity increases the likelihood of infection but not for the upper extremity. Higher Gustilo type open fractures have a higher incidence of infection for both upper and lower extremities. The results have important implications in an era of decreasing surgeon availability, especially in off hours. LEVEL OF EVIDENCE: Therapeutic study, level IV.

A review of the literature: direct and video laryngoscopy with simulation as educational intervention.

INTRODUCTION: A review of the literature was conducted to analyze the impact of simulation-based training for direct and video laryngoscopy (VL) skills for health care professionals and health care students. METHODS: This review focused on the published literature that used randomized controlled trials to examine the effectiveness of simulation-based training to develop airway management skills and identify pertinent literature by searching PubMed from inception of the database up to July 2013. This current review addresses the question of whether airway management simulation-based training improves the acquisition of resuscitation skills for health care profession learners. RESULTS: A total of eleven articles qualified for this systematic review based on the inclusion and exclusion criteria. These studies were analyzed and the specific simulators, participants, assessments, and details related to: time of intubation; Cormack and Lehane classification; success and failure rate; and number of attempts. CONCLUSION: This review suggests that simulation-based training is one effective way to teach VL skills. VL allows for a higher success rate, faster response time, and a decrease in the number of attempts by health care students and health care professionals under the conditions based on the eleven studies reviewed.

Findings of a randomized controlled trial using limited transthoracic echocardiogram (LTTE) as a hemodynamic monitoring tool in the trauma bay.

BACKGROUND: We hypothesize that limited transthoracic echocardiogram (LTTE) is a useful tool to guide therapy during the initial phase of resuscitation in trauma patients. METHODS: All highest-level alert patients with at least one measurement of systolic blood pressure less than 100 mm Hg, a mean arterial pressure less than 60 mm Hg, and/or a heart rate greater than 120 beats per minute who arrived to the trauma bay (TB) were randomized to have either LTTE performed (LTTEp) or not performed (non-LTTE) as part of their initial evaluation. Images were stored, and results were reported regarding contractility (good vs. poor), fluid status (empty inferior vena cava [hypovolemic] vs. full inferior vena cava [not hypovolemic]), and pericardial effusion (present vs. absent). Time from TB to operating room, intravenous fluid administration, blood product requirement, intensive care unit admission, and mortality were examined in both groups. RESULTS: A total of 240 patients were randomized. Twenty-five patients were excluded since they died upon arrival to the TB, leaving 215 patients in the study. Ninety-two patients were in the LTTEp group with 123 patients in the non-LTTE group. The LTTEp and non-LTTE groups were similar in age (38 years vs. 38.8 years, p = 0.75), Injury Severity Score (ISS) (19.2 vs. 19.0, p = 0.94), Revised Trauma Score (RTS) (5.5 vs. 6.0, p = 0.09), lactate (4.2 vs. 3.6, p = 0.14), and mechanism of injury (p = 0.44). Strikingly, LTTEp had significantly less intravenous fluid than non-LTTE patients (1.5 L vs. 2.5 L, p < 0.0001), less time from TB to operating room (35.6 minutes vs. 79.1 min, p = 0.0006), higher rate of intensive care unit admission (80.4% vs. 67.2%, p = 0.04), and a lower mortality rate (11% vs. 19.5%, p = 0.09). Mortality differences were particularly evident in the traumatic brain injury patients (14.7% in LTTEp vs. 39.5% in non-LTTE, p = 0.03). CONCLUSION: LTTE is a useful guide for therapy in hypotensive trauma patients during the early phase of resuscitation. LEVEL OF EVIDENCE: Therapeutic study, level II.

CT for all or selective approach? Who really needs a cervical spine CT after blunt trauma.

BACKGROUND: Computed tomography (CT) is the standard to screen blunt trauma patients for cervical spine (c-spine) fractures, yet there remains a reluctance to scan all trauma team activations because of radiation exposure and cost. The purpose of this study was to identify predictors of positive CT in an effort to decrease future CT use without compromising patient care. METHODS: We performed a prospective study in which we documented 18 combined NEXUS and Canadian c-spine criteria on 5,182 patients before CT comparing those with and without fractures to identify predictors of injury. Clinical examination was considered positive if any of the 18 criteria were positive. RESULTS: There were 324 patients with a fracture, for an incidence rate of 6.25%. Fracture patients were older (43.89 ± 18.83 years vs. 38.42 ± 17.45 years, p <; 0.0001), with a lower GCS (Glasgow Coma Scale) score (13.49 ± 3.49 vs. 14.32 ± 2.34, p < 0.0001), than nonfracture patients. Clinical examination had a 100% (324 of 324) sensitivity, 0.62% (30 of 4,858) specificity, 6.29% (324 of 5,152) positive predictive value, and 100% (30 of 30) negative predictive value. A total of 77.8% (14 of 18) criteria were significantly associated with fracture by univariate analysis, seven of which were independent predictors of fracture by logistic regression (midline tenderness, GCS score < 15, age ≥65 years, paresthesias, rollover motor vehicle collision, ejected, never in sitting position in emergency department). Evaluation of these seven factors demonstrated a sensitivity of 99.07% (321 of 324), positive predictive value of 6.95% (321 of 4,617), specificity of 11.57% (562 of 4,858), and negative predictive value of 99.47% (562 of 565). CONCLUSION: Although sensitive, the standard clinical criteria used to determine patients who need radiographs lack specificity. Based on these results, more narrow criteria should be validated in an effort to limit the number of c-spine CTs while not compromising patient care. LEVEL OF EVIDENCE: Prognostic study, level II; diagnostic study, level II.

Emergency tracheal intubation immediately following traumatic injury: an Eastern Association for the Surgery of Trauma practice management guideline.

BACKGROUND: The ABCs of trauma resuscitation begin with the airway evaluation, and effective airway management is imperative in the care of a patient with critical injury. The Eastern Association for the Surgery of Trauma Practice Management Guidelines committee aimed to update the guidelines for emergency tracheal intubation (ETI) published in 2002. These guidelines were made to assist clinicians with decisions regarding airway management for patients immediately following traumatic injury. The goals of the work group were to develop evidence-based guidelines to (1) characterize patients in need of ETI and (2) delineate the most appropriate procedure for patients undergoing ETI. METHODS: A search of the National Library of Medicine and the National Institutes of Health MEDLINE database was performed using PubMed (www.pubmed.gov). RESULTS: The search retrieved English-language articles published from 2000 to 2012 involving patients who had sustained blunt trauma, penetrating trauma, or heat-related injury and had developed respiratory system insufficiency or required ETI in the immediate period after injury (first 2 hours after injury). Sixty-nine articles were used to construct this set of practice management guidelines. CONCLUSION: The data supported the formation of six Level 1 recommendations, four Level 2 recommendations, and two Level 3 recommendations. In summary, the decision to intubate a patient following traumatic injury is based on multiple factors, including the need for oxygenation and ventilation, the extent and mechanism of injury, predicted operative need, or progression of disease. Rapid sequence intubation with direct laryngoscopy continues to be the recommended method for ETI, although the use of airway adjuncts such as blind insertion supraglottic devices and video laryngoscopy may be useful in facilitating successful ETI and may be preferred in certain patient populations. There is no pharmacologic induction agent of choice for ETI; however, succinylcholine is the neuromuscular blockade agent recommended for rapid sequence intubation.

Bladder pressure measurements and urinary tract infection in trauma patients.

BACKGROUND: The purpose of this trial was to determine if using a closed technique for bladder pressure measurements (BPMs) would eliminate them as a risk factor for urinary tract infection (UTI) in trauma patients, as was shown previously using an open technique. METHODS: Data were collected prospectively from January 2006 until December 2009 by a dedicated epidemiology nurse and combined with trauma registry data at our Level 1 trauma center. All trauma patients admitted to the surgical trauma intensive care unit (STICU) with and without UTIs were compared for demographic and epidemiologic data. A closed system was used in which the urinary drainage catheter (UDC) remained connected to the bag and 45 mL of saline was injected through a two-way valved sideport, with subsequent measurements through the sideport. RESULTS: There were 1,641 patients in the trial. The UTI group was sicker (Injury Severity Score [ISS] 18.7±11.9 no UTI vs. 28±10.7 UTI; p<0.0001), with longer stays (11.4±12.4 days no UTI vs. 37.9±20.3 days UTI; p<0.0001) and more UDC days (4.3±6.6 no UTI vs. 23.9±16.6 UTI; p<0.0001). The BPM group had more UDC days (15.6 days±16.0 BPM vs. 5.4 days±7.3 no BPM; p<0.0001), yet no difference in UTI rate/1,000 UDC days (5.7 no BPM vs. 8.0 BPM; p=0.5291). Logistic regression demonstrated only UDC days to be a predictor of UTI (1.125; 95% confidence interval [CI] 1.097-1.154; p<0.0001), whereas ISS (1.083, 95% CI 1.063-1.104; p<0.0001) and age (1.051, 95% CI 1.037-1.065; p<0.0001) were the only predictors of death. CONCLUSION: Although patients undergoing BPM have more UTIs than patients without BPM, the measurements are not an independent predictor of UTI when done by the closed technique. These findings emphasize the judicious use of BPM with a closed system and, more importantly, the need for early removal of catheters.

Geriatric education for surgical residents: identifying a major need.

This study evaluated a program designed to test and enhance residents' knowledge of geriatrics. A 2-year prospective interventional trial was conducted. Surgical residents underwent pretesting (pre) in three areas: polypharmacy, delirium, and end of life. They then received educational materials and completed a posttest within 1 month and a patient simulation examination graded by a physician observer and the patient on his or her satisfaction. Forty-nine residents (51% interns, 55% general surgery residents) participated. Seventy per cent had no prior geriatrics education. Test scores significantly improved from pretest to posttest (12.9 ± 3.1 vs 13.78 ± 3.12, P = 0.01). The scores were consistently better on poly topics and consistently worse on end-of-life topics: pretest per cent correct: polypharmacy 60, end of life 46, P = 0.007; posttest percent correct: polypharmacy 63, end of life 49, P = 0.0014. By Pearson correlation, the pretest and posttest scores did not correlate with either the observer (R = -0.16, P = 0.27 pre, R = -0.08, P = 0.59 post) or subscores (R = -0.27, P = 0.11 pre, R = -0.13, P = 0.45 post), although the observer and subscore correlated with each other (R = 0.35, P = 0.036). Performance was poor and did not correlate with better patient care by simulation. Other options for geriatric education need to be considered and evaluated.

Canadian Cervical Spine rule compared with computed tomography: a prospective analysis.

BACKGROUND: The Canadian cervical spine rule (CCS) has been found to be an effective tool to determine the need for radiographic evaluation of the cervical spine (c-spine) incorporating both clinical findings and mechanism. Previously, it has been validated only through clinical follow-up or selective use of X-rays. The purpose of this study was to validate it using computed tomography (CT) as the gold standard to identify fractures. METHODS: Prospective evaluation was performed on 3,201 blunt trauma patients who were screened by CCS and were compared with a complete c-spine CT. CSS positive indicated at least one positive clinical or mechanism finding, whereas CT positive indicated presence of a fracture. RESULTS: There were 192 patients with c-spine fractures versus 3,009 without fracture on CT. The fracture group was older (42.7 ± 19.0 years vs. 37.8 ± 17.5 years, p = 0.0006), had a lower Glasgow Coma Scale score (13.8 ± 4.2 vs. 14.4 ± 4.3, p < 0.0001), and lower systolic blood pressure (133.3 ± 23.8 mm Hg vs. 139.5 ± 23.1 mm Hg, p = 0.0023). The sensitivity of CCS was 100% (192/192), specificity was 0.60% (18/3009), positive predictive value was 6.03% (192/3183), and negative predictive value was 100% (18/18). Logistic regression identified only 8 of the 19 factors included in the CCS to be independent predictors of c-spine fracture. CONCLUSIONS: CCS is very sensitive but not very specific to determine the need for radiographic evaluation after blunt trauma. Based on this study, the rule should be streamlined to improve specificity while maintaining sensitivity.

National Emergency X-Radiography Utilization Study criteria is inadequate to rule out fracture after significant blunt trauma compared with computed tomography.

BACKGROUND: EAST guidelines now recommend computed tomography (CT) to evaluate cervical spine (c-spine) fractures after blunt trauma in patients who do not meet National Emergency X-Radiography Utilization Study criteria (NC), yet no imaging is required in those patients who do meet these criteria. NC are based on patients with both minor and severe (trauma team activation [TTA]) trauma. The purpose of this study was to evaluate the NC using CT as the gold standard in TTA patients. METHODS: We prospectively evaluated 2,606 blunt TTA patients at our Level I trauma center. NC defined as alertness (Glasgow Coma Scale [GCS] score = 15), evidence of intoxication, clinically distracting injury, midline c-spine tenderness, or neurologic deficits were documented. CT was used to determine the accuracy of these criteria. RESULTS: There were 157 patients with c-spine fractures and 2,449 patients without c-spine fractures. The fracture group was older (age, 43.4 years ± 19.3 years fracture group vs. 37.7 years ± 17.5 years no fracture group, p = 0.0003) with a lower GCS score (fracture group 13.7 ± 4.5 vs. no fracture group 14.4 ± 3.6, p = 0.0001) and initial systolic blood pressure (132.5 mm Hg ± 23.4 mm Hg vs. 139.9 mm Hg vs. 23.5 mm Hg, p = 0.0009). The sensitivity and specificity of clinical examination for all patients were 82.8% (130 of 157) and 45.7% (1,118 of 2,449), respectively. The positive predictive value (PPV) and negative predictive value (NPV) were 8.9% (130 of 1,461) and 97.6% (1,118 of 1,145), respectively. Patients with a GCS score of 15 had a sensitivity of 77%, specificity of 52.3%, PPV of 8.5%, and NPV of 97.5% for clinical examination. In those patients with the GCS score of 15, no intoxication or distracting injury, clinical examination had a sensitivity of 59.4%, specificity of 79.5%, PPV of 12.5%, and NPV of 97.5%. Of 26 patients with missed injuries based on NC, 19 (73.1%) required further intervention (16 collars, 2 OR, 1 Halo). CONCLUSION: As in our previous trial, NC is inaccurate compared with CT to diagnose c-spine fractures in TTA patients. CT should be used in all blunt TTA patients regardless of whether they meet NC.

Blunt splenic injuries in the adolescent trauma population: the role of angiography and embolization.

BACKGROUND: Splenic artery embolization (SAE) improves non-operative splenic salvage rates in adults, but its utility and safety in the pediatric population is less well defined. OBJECTIVE: Because adolescent trauma patients are often triaged to adult trauma centers, we were interested in evaluating SAE in this particular population. We hypothesize that angiography and embolization is a safe and effective adjunct to non-operative management in the adolescent population. METHODS: A retrospective review of all patients aged 13-17 years admitted to our Level I Trauma Center with blunt splenic injury from 1997-2005 was performed. We reviewed patient demographics, operative reports, admission, and follow-up abdominal computed tomography (ACT) results, angiographic reports, and patient outcomes. RESULTS: A total of 97 patients were reviewed. Eighteen patients underwent immediate surgery, and 79 of the remaining patients had planned non-operative management. Of those participating in non-operative management, 35/79 (44%) were initially observed and 44/79 (56%) underwent initial angiography, 23/44 having embolization. Patients in the embolization group had an overall high grade of injury (American Association for the Surgery of Trauma mean grade 3.3, SD 0.6). The overall splenic salvage rate was 96% (76/79) in the non-operative management group; 100% splenic salvage was seen in the observational group; 100% salvage was also seen in patients with negative angiography, and 87% salvage (20/23) in the splenic artery embolization group. CONCLUSION: Splenic artery embolization may be a valuable adjunct in adolescent blunt splenic injury, especially in higher grade injuries or with evidence of splenic vascular injury on ACT.

Flexion-extension cervical spine plain films compared with MRI in the diagnosis of ligamentous injury.

The purpose of this study was to compare flexion-extension (FE) plain films with MRI as the gold standard in the diagnosis of ligamentous injury (LI) of the cervical spine after trauma. A retrospective review of patients sustaining blunt trauma from January 2000 to December 2008 (n = 22929) who had both FE and MRI of the cervical spine was performed. Two hundred seventy-one patients had 303 FE films. Forty-nine also had MRI. The average Injury Severity Score was 15.6 +/- 10.2, Glasgow Coma Scale was 13.8 +/- 3.5, lactate 2.2 +/- 1.7 mmol/L, and hospital stay of 8 +/- 11.2 days. FE failed to identify all eight LIs seen on MRI. FE film sensitivity was 0 per cent (zero of eight), specificity 98 per cent (40 of 41), positive predictive value 0 per cent (zero of one), and negative predictive value 83 per cent (40 of 48). Although classified as negative for purposes of analysis, FE was incomplete 20.5 per cent (62 of 303) and ambiguous 9.2 per cent (28 of 303) of the time. The charge of FE is $535 so $48150 (90 incomplete/ambiguous films) could have been saved by eliminating these films. FE should no longer be used to diagnose LI. Given the rare incidence of these injuries, MRI should be used when there is high clinical suspicion of injury.

Current practice, demographics, and trends of critical care trained emergency physicians in the United States.

OBJECTIVES: Critical care medicine (CCM) is of growing interest among emergency physicians (EPs), but the number of CCM-trained EPs and their postfellowship practice is unknown. This study's purpose was to conduct a descriptive census survey of EPs who have completed or are currently in a CCM fellowship. METHODS: The authors created a Web-based survey, and requests to participate were sent to EPs who have completed or are currently in a CCM fellowship. Responses were collected over a 12-month period. Physicians were located via multiple whom electronic mailing lists, including the Emergency Medicine Section of the Society of Critical Care Medicine, Critical Care Section of the American College of Emergency Physicians, and the Emergency Medicine Residents' Association. The authors also contacted CCM fellowship coordinators and used informal networking. Data were collected on emergency medicine (EM) and other residency training; discipline, duration, and year of CCM fellowship; current practice setting; and board certification status, including the European Diploma in Intensive Care (EDIC). RESULTS: A total of 104 physicians completed the survey (97% response rate), of whom 73 had completed fellowship at the time of participation, and 31 of whom were in fellowship training. Of those who completed fellowship, 36/73 (49%) practice both EM and CCM, and 45/73 (62%) practice in academic institutions. Multiple disciplines of fellowship were represented: multidisciplinary (39), surgical (28), internal medicine (16), anesthesia (14), and other (4). Together, the CCM fellowships at the University of Maryland R Adams Cowley Shock Trauma Center and the University of Pittsburgh have trained 42% of all EM-CCM physicians, with 38 other institutions training from one to four fellows each. The number of EPs completing CCM fellowships has risen: from 1974 to 1989, 12 EPs; from 1990 to 1999, 15 EPs; and from 2000 to 2007, 43 EPs. CONCLUSIONS: Emergency physicians are entering CCM fellowships in increasing numbers. Almost half of these EPs practice both EM and CCM.

Do flexion extension plain films facilitate treatment after trauma?

We hypothesized that flexion extension (FE) films do not facilitate the diagnosis or treatment of ligamentous injury of the cervical spine after blunt trauma. From January 2000 to December 2008 we reviewed all patients who underwent FE films and compared five-view plain films (5 view) and cervical spine CTC with FE in the diagnosis of ligamentous injury. There were 22,929 patients with blunt trauma and of these, 271 patients underwent 303 FE films. Average age was 39.6 years, Injury Severity Score was 10.8, Glasgow Coma Score was 14.1, lactate was 2.6 mmol/L, and hospital length of stay was 6 days. Compared with FE, 5 view and CTC had a sensitivity of 80 per cent (8 of 10), positive predictive value of 47.1 per cent (8 of 17), specificity of 96.55 per cent (252 of 261), and negative predictive value of 99.21 per cent (252 of 254). For purposes of analysis, incomplete and ambiguous FE films were listed as negative; however, 20.5 per cent (62 of 303) were incomplete and 9.2 per cent (28 of 303) were ambiguous. Management did not change for the 2 patients with missed ligament injuries. The 303 studies cost $162,105.00 to obtain. FEs are often incomplete and unreliable making it difficult to use them to base management decisions. They do not facilitate treatment and may lead to increased cost and prolonged cervical collars.

Practice management guidelines for identification of cervical spine injuries following trauma: update from the eastern association for the surgery of trauma practice management guidelines committee.

BACKGROUND: Injury to the cervical spine (CS) is common after major trauma. The Eastern Association for the Surgery of Trauma first published its Practice Management Guidelines for the evaluation of CS injury in 1998. A subsequent revision was published in 2000. Since that time a large volume of literature has been published. As a result, the Practice Management Guidelines Committee set out to develop updated guidelines for the identification of CS injury. METHODS: A search of the National Library of Medicine and the National Institutes of Health MEDLINE database was performed using PubMed (www.pubmed.gov). The search retrieved English language articles regarding the identification of CS injury from 1998 to 2007. The questions posed were: who needs CS imaging; what imaging should be obtained; when should computed tomography, magnetic resonance imaging, or flexion/extension radiographs be used; and how is significant ligamentous injury excluded in the comatose patient? RESULTS: Seventy-eight articles were identified. From this group, 52 articles were selected to construct the guidelines. CONCLUSION: There have been significant changes in practice since the previous CS injury guidelines. Most significantly, computed tomography has supplanted plain radiography as the primary screening modality in those who require imaging. Clinical clearance remains the standard in awake, alert patients with trauma without neurologic deficit or distracting injury who have no neck pain or tenderness with full range of motion. Cervical collars should be removed as soon as feasible. Controversy persists regarding CS clearance in the obtunded patient without gross neurologic deficit.
