RESUMEN
OBJECTIVE: Mechanical ventilation with low tidal volumes has been shown to improve outcomes for patients both with and without acute respiratory distress syndrome. This study aims to characterize mechanically ventilated patients in the emergency department (ED), describe the initial ED ventilator settings, and assess for associations between lung protective ventilation strategies in the ED and outcomes. METHODS: This was a multicenter, prospective, observational study of mechanical ventilation at 3 academic EDs. We defined lung protective ventilation as a tidal volume of less than or equal to 8 mL/kg of predicted body weight and compared outcomes for patients ventilated with lung protective vs non-lung protective ventilation, including inhospital mortality, ventilator days, intensive care unit length of stay, and hospital length of stay. RESULTS: Data from 433 patients were analyzed. Altered mental status without respiratory pathology was the most common reason for intubation, followed by trauma and respiratory failure. Two hundred sixty-one patients (60.3%) received lung protective ventilation, but most patients were ventilated with a low positive end-expiratory pressure, high fraction of inspired oxygen strategy. Patients were ventilated in the ED for a mean of 5 hours and 7 minutes but had few ventilator adjustments. Outcomes were not significantly different between patients receiving lung protective vs non-lung protective ventilation. CONCLUSIONS: Nearly 40% of ED patients were ventilated with non-lung protective ventilation as well as with low positive end-expiratory pressure and high fraction of inspired oxygen. Despite a mean ED ventilation time of more than 5 hours, few patients had adjustments made to their ventilators.

BACKGROUND: Although Emergency physicians frequently intubate patients, management of mechanical ventilation has not been emphasized in emergency medicine (EM) residency curricula. OBJECTIVES: The objective of this study was to quantify EM residents' education, experience, and knowledge regarding mechanical ventilation. METHODS: We developed a survey of residents' educational experiences with ventilators and an assessment tool with nine clinical questions. Correlation and regression analyses were performed to evaluate the relationship between residents' scores on the assessment instrument and their training, education, and comfort with ventilation. RESULTS: Of 312 EM residents, 218 responded (69.9%). The overall correct response rate for the assessment tool was 73.3%, standard deviation (SD) ± 22.3. Seventy-seven percent (n = 167) of respondents reported ≤ 3 h of mechanical ventilation education in their residency curricula over the past year. Residents reported frequently caring for ventilated patients in the ED, as 64% (n = 139) recalled caring for ≥ 4 ventilated patients per month. Fifty-three percent (n = 116) of residents endorsed feeling comfortable caring for mechanically ventilated ED patients. In multiregression analysis, the only significant predictor of total test score was residents' comfort with caring for mechanically ventilated patients (F = 10.963, p = 0.001). CONCLUSIONS: EM residents report caring for mechanically ventilated patients frequently, but receive little education on mechanical ventilation. Furthermore, as residents' performance on the assessment tool is only correlated with their self-reported comfort with caring for ventilated patients, these results demonstrate an opportunity for increased educational focus on mechanical ventilation management in EM residency training.

BACKGROUND: Emergent intubation is associated with a high rate of complications. Neuromuscular blocking agents are routinely used in the operating room and emergency department to facilitate intubation. However, use of neuromuscular blocking agents during emergent airway management outside of the operating room and emergency department is controversial. We hypothesized that the use of neuromuscular blocking agents is associated with a decreased prevalence of hypoxemia and reduced rate of procedure-related complications. METHODS: Five hundred sixty-six patients undergoing emergent intubations in two tertiary care centers, Massachusetts General Hospital, Boston, MA, and the University of California Los Angeles, Ronald Reagan Medical Center, Los Angeles, CA, were enrolled in a prospective, observational study. The 112 patients intubated during cardiopulmonary resuscitation were excluded, leaving 454 patients for analysis. All intubations were supervised by attendings trained in Critical Care Medicine. We measured intubating conditions, oxygen saturation during and 5 mins following intubation. We assessed the prevalence of procedure-related complications defined as esophageal intubation, traumatic intubation, aspiration, dental injury, and endobronchial intubation. RESULTS: The use of neuromuscular blocking agents was associated with a lower prevalence of hypoxemia (10.1% vs. 17.4%, p = .022) and a lower prevalence of procedure-related complications (3.1% vs. 8.3%, p = .012). This association persisted in a multivariate analysis, which controlled for airway grade, sedation, and institution. Use of neuromuscular blocking agents was associated with significantly improved intubating conditions (laryngeal view, p = .014; number of intubation attempts, p = .049). After controlling for the number of intubation attempts and laryngoscopic view, muscle relaxant use is an independent predictor of complications associated with emergency intubation (p = .037), and there is a trend towards improvement of oxygenation (p = .07). CONCLUSION: The use of neuromuscular blocking agents, when used by intensivists with a high level of training and experience, is associated with a decrease in procedure-related complications.

BACKGROUND: Early treatment of sepsis in Emergency Department (ED) patients has lead to improved outcomes, making early identification of the disease essential. The presence of systemic inflammatory response criteria aids in recognition of infection, although the reliability of these markers is variable. STUDY OBJECTIVE: This study aims to quantify the ability of abnormal temperature, white blood cell (WBC) count, and bandemia to identify bacteremia in ED patients with suspected infection. METHODS: This was a post hoc analysis of data collected for a prospective, observational, cohort study. Consecutive adult (age ≥ 18 years) patients who presented to the ED of a tertiary care center between February 1, 2000 and February 1, 2001 and had blood cultures obtained in the ED or within 3 h of admission were enrolled. Patients with bacteremia were identified and charts were reviewed for presence of normal temperature (36.1-38°C/97-100.4°F), normal WBC (4-12 K/µL), and presence of bandemia (> 5% of WBC differential). RESULTS: There were 3563 patients enrolled; 289 patients (8.1%) had positive blood cultures. Among patients with positive blood cultures, 33% had a normal body temperature and 52% had a normal WBC count. Bandemia was present in 80% of culture-positive patients with a normal temperature and 79% of culture-positive patients with a normal WBC count. Fifty-two (17.4%) patients with positive blood cultures had neither an abnormal temperature nor an abnormal WBC. CONCLUSION: A significant percentage of ED patients with blood culture-proven bacteremia have a normal temperature and WBC count upon presentation. Bandemia may be a useful clue for identifying occult bacteremia.

The sepsis resuscitation bundle is the result of an effort on behalf of the Surviving Sepsis Campaign and the Institute for Healthcare Improvement to translate individual guideline recommendations into standardized, achievable goals for physicians caring for the critically ill patient. Implementation of this bundle is associated with decreased mortality. Many of the bundle items reflect components of therapy shown to improve mortality in the seminal early goal-directed therapy trial for severe sepsis and septic shock, including an initial lactate measurement. Elevations in serum lactate are associated with increased mortality, and may result from either increased lactate production or impaired lactate clearance. Lactate clearance may be an important addition to the monitoring and management bundles of patients with severe sepsis and septic shock, However, specific mechanisms of lactate clearance, the relation of lactate clearance to traditional hemodynamic parameters, and the importance of lactate clearance as a therapeutic target or monitoring tool remain unclear.

BACKGROUND: Morbidity and Mortality conferences (M&M) are used to meet many of the Core Competencies required by the Accreditation Council of Graduate Medical Education for residency training programs. This study seeks to describe and quantify different types of M&M conferences among Emergency Medicine (EM) training programs. METHODS: A confidential survey was e-mailed to the Program Directors (PD) or Assistant PD of all United States (US) Emergency Medicine residency training programs with functional e-mail addresses listed in the Society for Academic Emergency Medicine residency catalog. Descriptive statistics and 95% confidence (CI) intervals are reported. RESULTS: Of 124 surveys sent out, 89 (72%) completed surveys were returned. There were 88 programs (99%, CI 93-100%) that reported having an M&M. Conferences are held monthly at 67% (CI 57-76%) of programs. Cases for discussion are identified by an EM attending, quality assurance committee, or resident (70%, 57%, and 48%, respectively). Half of programs reported that > 40% of the cases involve systems errors. Twenty percent of programs report that > 40% of the cases involve deaths. Consultants are invited at 44% of programs, and 20% of programs specifically invite radiologists. If a medical error is identified in the M&M, 79% (70-86%) of programs have a protocol for addressing the error. CONCLUSION: EM training programs almost uniformly have an M&M, but these conferences vary in frequency, content, and attendance. Future studies are needed to investigate resident and faculty perceptions of M&M, its educational impact, and ways to improve the conference.

BACKGROUND: Mechanically ventilated patients increasingly spend hours in emergency department beds before ICU admission. This study evaluated the performance of blood gases in mechanically ventilated subjects in the emergency department and subsequent changes to mechanical ventilation settings. METHODS: This was a multi-center, prospective, observational study of subjects ventilated in the emergency department, conducted at 3 academic emergency departments from July 2011 to March 2013. We measured the rate of arterial blood gas (ABG) and venous blood gas (VBG) analysis, and we assessed the associations between the conditions of hypoxemia, hyperoxia, hypercapnia, or acidemia and changes to mechanical ventilator settings. RESULTS: Of 292 ventilated subjects, 17.1% did not have a blood gas sent in the emergency department. Ventilator changes were made significantly more frequently for subjects who had an ABG as the initial blood gas sent in the emergency department (odds ratio 2.70, 95% CI 1.46-4.99, P = .002). However, findings of hypoxemia, hyperoxia, hypercapnia, or acidemia were not correlated with ventilator adjustments. CONCLUSIONS: In this prospective observational study of subjects mechanically ventilated in the emergency department, the majority had a blood gas checked while in the emergency department. While ABGs were associated with having changes made to ventilator settings in the emergency department, clinical findings of hypoxemia, hyperoxia, hypercapnia, and acidemia were not. Inattention to blood gas results may lead to missed opportunities in guiding ventilator changes in the emergency department.

INTRODUCTION: Due to hospital crowding, mechanically ventilated patients are increasingly spending hours boarding in emergency departments (ED) before intensive care unit (ICU) admission. This study aims to evaluate the association between time ventilated in the ED and in-hospital mortality, duration of mechanical ventilation, ICU and hospital length of stay (LOS). METHODS: This was a multi-center, prospective, observational study of patients ventilated in the ED, conducted at three academic Level I Trauma Centers from July 2011 to March 2013. All consecutive adult patients on invasive mechanical ventilation were eligible for enrollment. We performed a Cox regression to assess for a mortality effect for mechanically ventilated patients with each hour of increasing LOS in the ED and multivariable regression analyses to assess for independently significant contributors to in-hospital mortality. Our primary outcome was in-hospital mortality, with secondary outcomes of ventilator days, ICU LOS and hospital LOS. We further commented on use of lung protective ventilation and frequency of ventilator changes made in this cohort. RESULTS: We enrolled 535 patients, of whom 525 met all inclusion criteria. Altered mental status without respiratory pathology was the most common reason for intubation, followed by trauma and respiratory failure. Using iterated Cox regression, a mortality effect occurred at ED time of mechanical ventilation > 7 hours, and the longer ED stay was also associated with a longer total duration of intubation. However, adjusted multivariable regression analysis demonstrated only older age and admission to the neurosciences ICU as independently associated with increased mortality. Of interest, only 23.8% of patients ventilated in the ED for over seven hours had changes made to their ventilator. CONCLUSION: In a prospective observational study of patients mechanically ventilated in the ED, there was a significant mortality benefit to expedited transfer of patients into an appropriate ICU setting.

PURPOSE: Prior descriptions of the psychometric properties of validated knowledge assessment tools designed to determine Emergency medicine (EM) residents understanding of physiologic and clinical concepts related to mechanical ventilation are lacking. In this setting, we have performed this study to describe the psychometric and performance properties of a novel knowledge assessment tool that measures EM residents' knowledge of topics in mechanical ventilation. METHODS: Results from a multicenter, prospective, survey study involving 219 EM residents from 8 academic hospitals in northeastern United States were analyzed to quantify reliability, item difficulty, and item discrimination of each of the 9 questions included in the knowledge assessment tool for 3 weeks, beginning in January 2013. RESULTS: The response rate for residents completing the knowledge assessment tool was 68.6% (214 out of 312 EM residents). Reliability was assessed by both Cronbach's alpha coefficient (0.6293) and the Spearman-Brown coefficient (0.6437). Item difficulty ranged from 0.39 to 0.96, with a mean item difficulty of 0.75 for all 9 questions. Uncorrected item discrimination values ranged from 0.111 to 0.556. Corrected item-total correlations were determined by removing the question being assessed from analysis, resulting in a range of item discrimination from 0.139 to 0.498. CONCLUSION: Reliability, item difficulty and item discrimination were within satisfactory ranges in this study, demonstrating acceptable psychometric properties of this knowledge assessment tool. This assessment indicates that this knowledge assessment tool is sufficiently rigorous for use in future research studies or for assessment of EM residents for evaluative purposes.

INTRODUCTION: Although emergency physicians frequently intubate patients, management of mechanical ventilation has not been emphasized in emergency medicine (EM) education or clinical practice. The objective of this study was to quantify EM attendings' education, experience, and knowledge regarding mechanical ventilation in the emergency department. METHODS: We developed a survey of academic EM attendings' educational experiences with ventilators and a knowledge assessment tool with nine clinical questions. EM attendings at key teaching hospitals for seven EM residency training programs in the northeastern United States were invited to participate in this survey study. We performed correlation and regression analyses to evaluate the relationship between attendings' scores on the assessment instrument and their training, education, and comfort with ventilation. RESULTS: Of 394 EM attendings surveyed, 211 responded (53.6%). Of respondents, 74.5% reported receiving three or fewer hours of ventilation-related education from EM sources over the past year and 98 (46%) reported receiving between 0-1 hour of education. The overall correct response rate for the assessment tool was 73.4%, with a standard deviation of 19.9. The factors associated with a higher score were completion of an EM residency, prior emphasis on mechanical ventilation during one's own residency, working in a setting where an emergency physician bears primary responsibility for ventilator management, and level of comfort with managing ventilated patients. Physicians' comfort was associated with the frequency of ventilator changes and EM management of ventilation, as well as hours of education. CONCLUSION: EM attendings report caring for mechanically ventilated patients frequently, but most receive fewer than three educational hours a year on mechanical ventilation, and nearly half receive 0-1 hour. Physicians' performance on an assessment tool for mechanical ventilation is most strongly correlated with their self-reported comfort with mechanical ventilation.

BACKGROUND: Fluid responsiveness is a measure of preload dependence and is defined as an increase in cardiac output due to volume expansion. Recent publications have suggested that variation in amplitude of the pulse oximetry waveform may be predictive of fluid responsiveness. The pleth variability index (PVI) was developed as a noninvasive bedside measurement of this variation in the pulse oximetry waveform. OBJECTIVES: To measure the discriminatory value of PVI for predicting fluid responsiveness as measured by pulmonary artery catheter thermodilution in patients after cardiothoracic surgery. METHODS: A prospective observational study of hemodynamically stable postoperative cardiac surgery patients with pulmonary artery catheters. A fingertip sensor was used to measure PVI. Vital signs, PVI, and cardiac index were measured before, during, and after passive leg raise. Fluid responsiveness was defined by increase in cardiac index of greater than 15% during passive leg raise. The discriminatory value of PVI was assessed by using the Wilcoxon method to measure the area under the receiver operating curve. RESULTS: In 13 months, 47 patients (24 receiving mechanical ventilation, 23 spontaneously breathing) were enrolled. Fluid responsiveness was noted in 42% of intubated patients and 48% of spontaneously breathing patients. PVI was not adequate to discriminate fluid responsiveness in intubated patients (area under curve, 0.63; P = .16) or spontaneously breathing patients (area under curve, 0.41; P = .75). CONCLUSIONS: Among postoperative cardiac surgery patients, PVI is not reliable for predicting fluid responsiveness as measured by pulmonary artery catheter thermodilution, regardless of ventilatory status.

INTRODUCTION: Previous literature has shown gender disparities in the care of acute ischemic stroke. Compared to men, women wait longer for brain imaging and are less likely to receive intravenous (IV) tissue plasminogen activator (tPA). Emergency department (ED) triage is an important step in the rapid assessment of stroke patients and is a possible contributor to disparities. It is unknown whether gender differences exist in ED triage of acute stroke patients. Our primary objective was to determine whether gender disparities exist in the triage of acute stroke patients as defined by Emergency Severity Index (ESI) levels and use of ED critical care beds. METHODS: This was a retrospective, observational study of both ischemic and hemorrhagic stroke patients age ≥18 years presenting to a large, urban, academic ED within six hours of symptom onset between January 2010, and December 2012. Primary outcomes were triage to a non-critical ED bed and Emergency Severity Index (ESI) level. Primary outcome data were extracted from electronic medical records by a blinded data manager; secondary outcome data and covariates were abstracted by trained research assistants. We performed bivariate and multivariate analyses. Logistic regression was performed using age, race, insurance status, mode of and time to arrival, National Institutes of Health Stroke Scale, and presence of atypical symptoms as covariates. RESULTS: There were 537 patients included in this study. Women were older (75.6 vs. 69.5, p<0.001), and more women had a history of atrial fibrillation (39.8% vs. 25.3%, p<0.001). Compared to 9.5% of men, 10.3% of women were triaged to a non-critical care ED bed (p=0.77); 92.1% of women were triaged as ESI 1 or 2 vs. 93.6% of men (p=0.53). After adjustment, gender was not associated with triage location or ESI level, though atypical symptoms were associated with higher odds of being triaged to a non-critical care bed (aOR 1.98, 95%CI [1.03 - 3.81]) and 3.04 times higher odds of being triaged as ESI 3 vs. ESI 1 or 2 (95% CI [1.36 - 6.82]). CONCLUSION: In a large, urban, academic ED at a primary stroke center, there were no gender differences in triage to critical care beds or ESI levels among acute stroke patients arriving within six hours of symptom onset. These findings suggest that ED triage protocols for stroke patients may be effective in minimizing gender disparities in care.

OBJECTIVES: Bispectral analysis of single-lead electroencephalographs (BIS) has proven valuable in assessing the level of awareness in sedated patients. In this study, the authors sought to determine if BIS values had a predictive value in patients with traumatic brain injuries (TBIs). Therefore, the objective was to determine in emergency department (ED) patients presenting with head trauma whether BIS and Glasgow Coma Scale score (GCS) prior to sedation would be sensitive and specific in predicting TBI. METHODS: A convenience sample of patients with known or suspected head trauma presenting between June and August of both 2001 and 2002 were entered into the study by having a BIS monitor placed immediately on presentation to the ED. BIS and GCS scores were collected every 2 minutes. Head computed tomography (CT) results and discharge dictations were then evaluated to determine the presence of TBI. RESULTS: Fifty-two patients were entered into the study; 13 were excluded due to receiving sedatives prior to enrollment. Of the remaining 39 patients, 14 had intracranial hemorrhage on initial head CT. Of these 14, two had BIS scores over 95. Both of these were neurologically intact at discharge. Eleven of the 12 remaining patients died or left the hospital neurologically impaired. Of the patients with no abnormalities on initial head CT, 19 of 25 had initial BIS scores >95 and all left the hospital neurologically intact. Of the patients with normal initial head CT and initial BIS scores < 95, four of six died or were neurologically impaired at discharge. Twenty of 39 patients presented with an initial GCS of 15; four of 20 had an initial BIS score < 95, three of whom were neurologically impaired at discharge. The 16 of 20 with BIS >95 left the hospital neurologically intact. All patients with a GCS of 14 had BIS scores >95 and left the hospital neurologically intact. All patients with a GCS of 13 had initial BIS scores < 95 and were neurologically impaired at discharge. One patient with a GCS of 11 and a BIS score of 67 left the hospital neurologically intact; all other patients with a GCS < 12 had a BIS < 95 and left the hospital with a neurologic deficit. CONCLUSIONS: BIS scores obtained prior to sedative medicines in the face of trauma are predictive of TBI and neurologic outcome at discharge.

Cerebrovascular neurologic emergencies including ischemic and hemorrhagic stroke, subarachnoid hemorrhage (SAH), and migraine are leading causes of death and disability that are frequently diagnosed and treated in the emergency department (ED). Although sex and gender differences in neurologic emergencies are beginning to become clearer, there are many unanswered questions about how emergency physicians should incorporate sex and gender into their research initiatives, patient evaluations, and overall management plans for these conditions. After evaluating the existing gaps in the literature, a core group of ED researchers developed a draft of future research priorities. Participants in the 2014 Academic Emergency Medicine consensus conference neurologic emergencies working group then discussed and approved the recommended research agenda using a standardized nominal group technique. Recommendations for future research on the role of sex and gender in the diagnosis, treatment, and outcomes pertinent to ED providers are described for each of three diagnoses: stroke, SAH, and migraine. Recommended future research also includes investigation of the biologic and pathophysiologic differences between men and women with neurologic emergencies as they pertain to ED diagnoses and treatments.

The influence of sex and gender on patient care is just being recognized in emergency medicine (EM). Providers are realizing the need to improve outcomes for both men and women by incorporating sex- and gender-specific science into clinical practice, while EM researchers are now beginning to study novel sex- and gender-specific perspectives in the areas of acute care research. This article serves as an update on the sex differences in a variety of acute clinical care topics within the field of EM and showcases opportunities for improving patient care outcomes and expanding research to advance the science of gender-specific emergency care.

Sheehan's syndrome is a well described entity that refers to hypopituitarism with pituitary infarction secondary to postpartum shock or hemorrhage. Antepartum pituitary infarction is a very rare condition that has been reported only in patients with longstanding type 1 diabetes mellitus or uncontrolled gestational diabetes. A case of severe, acute hypopituitarism in the setting of hemorrhagic shock from a gunshot wound is presented. Our case report highlights the importance of including hypopituitarism in the differential diagnosis of a critically ill parturient.

UNLABELLED: The bispectral index (BIS) may be a useful monitor to predict the level of awareness in patients undergoing procedural sedation in the emergency department (ED). OBJECTIVES: The authors hypothesized that using the BIS during procedural sedation in the ED would increase the recognition of adequately sedated patients, thus reducing oversedation and the corresponding increased rate of respiratory depression (RD). As a result, the occurrence of RD would be reduced. METHODS: This was a prospective randomized study of ED procedural sedation with propofol. Sedations were randomized to have the treating physician either blinded or not blinded to information from the BIS monitor. Vital signs, pulse oximetry, end-tidal carbon dioxide (ETCO(2)), propofol dosage, and the BIS score were recorded. RD was defined as a change in ETCO(2) greater than 10 mm Hg, an oxygen saturation of less than 90% at any time, or an absent ETCO(2) waveform. The RD rates were compared with chi-square tests. RESULTS: One hundred five patients were enrolled in the study; five were excluded due to study protocol violations. No serious adverse events were reported. RD was seen in 29 of 100 (29%) patients; 18 of 48 in the BIS-blinded group and 11 of 52 in the BIS-unblinded group had RD (p = 0.06). For patients requiring only a single dose of propofol, three of 15 in the BIS-blinded group and four of 18 in the BIS-unblinded group met the criteria for RD (p = 0.87). For patients requiring multiple doses of propofol, 15 of 33 patients in the BIS-blinded group and seven of 34 patients in the BIS-unblinded group met criteria for RD (p = 0.02). The mean BIS nadir for BIS-blinded patients was 60.9 (95% CI = 56.9 to 65.0) and that for BIS-unblinded patients was 63.2 (95% CI = 57.7 to 65.3) (p = 0.22). CONCLUSIONS: There was a lower rate of RD when physicians had access to the BIS during procedural sedations. This difference was greater in sedations requiring multiple doses of propofol. There was no difference in the rate of RD when only a single dose was given.
