OBJECTIVE: Numerous factors can cause delays in transfer to an intensive care unit for critically ill emergency department patients. The impact of delays is unknown. We aimed to determine the association between emergency department "boarding" (holding admitted patients in the emergency department pending intensive care unit transfer) and outcomes for critically ill patients. DESIGN: This was a cross-sectional analytical study using the Project IMPACT database (a multicenter U.S. database of intensive care unit patients). Patients admitted from the emergency department to the intensive care unit (2000-2003) were included and divided into two groups: emergency department boarding >or=6 hrs (delayed) vs. emergency department boarding <6 hrs (nondelayed). Demographics, intensive care unit procedures, length of stay, and mortality were analyzed. Groups were compared using chi-square, Mann-Whitney, and unpaired Student's t-tests. SETTING: Emergency department and intensive care unit. PATIENTS: Patients admitted from the emergency department to the intensive care unit (2000-2003). INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Main outcomes were intensive care unit and hospital survival and intensive care unit and hospital length of stay. During the study period, 50,322 patients were admitted. Both groups (delayed, n = 1,036; nondelayed, n = 49,286) were similar in age, gender, and do-not-resuscitate status, along with Acute Physiology and Chronic Health Evaluation II score in the subgroup for which it was recorded. Among hospital survivors, the median hospital length of stay was 7.0 (delayed) vs. 6.0 days (nondelayed) (p < .001). Intensive care unit mortality was 10.7% (delayed) vs. 8.4% (nondelayed) (p < .01). In-hospital mortality was 17.4% (delayed) vs. 12.9% (nondelayed) (p < .001). In the stepwise logistic model, delayed admission, advancing age, higher Acute Physiology and Chronic Health Evaluation II score, male gender, and diagnostic categories of trauma, intracerebral hemorrhage, and neurologic disease were associated with lower hospital survival (odds ratio for delayed admission, 0.709; 95% confidence interval, 0.561-0.895). CONCLUSIONS: Critically ill emergency department patients with a >or=6-hr delay in intensive care unit transfer had increased hospital length of stay and higher intensive care unit and hospital mortality. This suggests the need to identify factors associated with delayed transfer as well as specific determinants of adverse outcomes.

OBJECTIVE: The objective was to assess anxiety and burnout levels, home life changes, and measures to relieve stress of U.S. academic emergency medicine (EM) physicians during the COVID-19 pandemic acceleration phase. METHODS: We sent a cross-sectional e-mail survey to all EM physicians at seven academic emergency departments. The survey incorporated items from validated stress scales and assessed perceptions and key elements in the following domains: numbers of suspected COVID-19 patients, availability of diagnostic testing, levels of home and workplace anxiety, severity of work burnout, identification of stressors, changes in home behaviors, and measures to decrease provider anxiety. RESULTS: A total of 426 (56.7%) EM physicians responded. On a scale of 1 to 7 (1 = not at all, 4 = somewhat, and 7 = extremely), the median (interquartile range) reported effect of the pandemic on both work and home stress levels was 5 (4-6). Reported levels of emotional exhaustion/burnout increased from a prepandemic median (IQR) of 3 (2-4) to since the pandemic started a median of 4 (3-6), with a difference in medians of 1.8 (95% confidence interval = 1.7 to 1.9). Most physicians (90.8%) reported changing their behavior toward family and friends, especially by decreasing signs of affection (76.8%). The most commonly cited measures cited to alleviate stress/anxiety were increasing personal protective equipment (PPE) availability, offering rapid COVID-19 testing at physician discretion, providing clearer communication about COVID-19 protocol changes, and assuring that physicians can take leave for care of family and self. CONCLUSIONS: During the acceleration phase, the COVID-19 pandemic has induced substantial workplace and home anxiety in academic EM physicians, and their exposure during work has had a major impact on their home lives. Measures cited to decrease stress include enhanced availability of PPE, rapid turnaround testing at provider discretion, and clear communication about COVID-19 protocol changes.

OBJECTIVE: Emergency Departments (EDs) offer an opportunity to improve the care of patients with at-risk and dependent drinking by teaching staff to screen, perform brief intervention and refer to treatment (SBIRT). We describe here the implementation at 14 Academic EDs of a structured SBIRT curriculum to determine if this learning experience improves provider beliefs and practices. METHODS: ED faculty, residents, nurses, physician extenders, social workers, and Emergency Medical Technicians (EMTs) were surveyed prior to participating in either a two hour interactive workshops with case simulations, or a web-based program (www.ed.bmc.org/sbirt). A pre-post repeated measures design assessed changes in provider beliefs and practices at three and 12 months post-exposure. RESULTS: Among 402 ED providers, 74% reported < 10 hours of prior professional alcohol-related education and 78% had < 2 hours exposure in the previous year. At 3-month follow-up, scores for self-reported confidence in ability, responsibility to intervene, and actual utilization of SBIRT skills all improved significantly over baseline. Gains decreased somewhat at 12 months, but remained above baseline. Length of time in practice was positively associated with SBIRT utilization, controlling for gender, race and type of profession. Persistent barriers included time limitations and lack of referral resources. CONCLUSIONS: ED providers respond favorably to SBIRT. Changes in utilization were substantial at three months post-exposure to a standardized curriculum, but less apparent after 12 months. Booster sessions, trained assistants and infrastructure supports may be needed to sustain changes over the longer term.

IMPORTANCE: Chest radiography (chest x-ray [CXR] and chest computed tomography [CT]) is the most common imaging in blunt trauma evaluation. Unnecessary trauma imaging leads to greater costs, emergency department time, and patient exposure to ionizing radiation. OBJECTIVE To validate our previously derived decision instrument (NEXUS Chest) for identification of blunt trauma patients with very low risk of thoracic injury seen on chest imaging (TICI). We hypothesized that NEXUS Chest would have high sensitivity (>98%) for the prediction of TICI and TICI with major clinical significance. DESIGN, SETTING, AND PARTICIPANTS: From December 2009 to January 2012, we enrolled blunt trauma patients older than 14 years who received chest radiography in this prospective, observational, diagnostic decision instrument study at 9 US level I trauma centers. Prior to viewing radiographic results, physicians recorded the presence or absence of the NEXUS Chest 7 clinical criteria (age >60 years, rapid deceleration mechanism, chest pain, intoxication, abnormal alertness/mental status, distracting painful injury, and tenderness to chest wall palpation). MAIN OUTCOMES AND MEASURES: Thoracic injury seen on chest imaging was defined as pneumothorax, hemothorax, aortic or great vessel injury, 2 or more rib fractures, ruptured diaphragm, sternal fracture, and pulmonary contusion or laceration seen on radiographs. An expert panel generated an a priori classification of clinically major, minor, and insignificant TICIs according to associated management changes. RESULTS: Of 9905 enrolled patients, 43.1% had a single CXR, 42.0% had CXR and chest CT, 6.7% had CXR and abdominal CT (without chest CT), 5.5% had multiple CXRs without CT, and 2.6% had chest CT alone in the emergency department. The most common trauma mechanisms were motorized vehicle crash (43.9%), fall (27.5%), pedestrian struck by motorized vehicle (10.7%), bicycle crash (6.3%), and struck by blunt object, fists, or kicked (5.8%). Thoracic injury seen on chest imaging was seen in 1478 (14.9%) patients with 363 (24.6%) of these having major clinical significance, 1079 (73.0%) minor clinical significance, and 36 (2.4%) no clinical significance. NEXUS Chest had a sensitivity of 98.8% (95% CI, 98.1%-99.3%), a negative predictive value of 98.5% (95% CI, 97.6%.6-99.1%), and a specificity of 13.3% (95% CI, 12.6%-14.1%) for TICI. The sensitivity and negative predictive value for TICI with clinically major injury were 99.7% (95% CI, 98.2%-100.0%) and 99.9% (95% CI, 99.4%-100.0%), respectively. CONCLUSIONS AND RELEVANCE: We have validated the NEXUS Chest decision instrument, which may safely reduce the need for chest imaging in blunt trauma patients older than 14 years.
