Uncontrolled hemorrhagic shock is the leading cause of potentially preventable death in major trauma patients. Damage control resuscitation (DCR), a strategy combining the techniques of permissive hypotension, hemostatic resuscitation, and damage control surgery, has been highly recommended for trauma patients. This study investigated whether emergency department (ED) crowding was associated with poor performance of the DCR strategies in treating hemorrhagic shock trauma patients. ⋯ ED crowding was associated with poor performance of DCR for major trauma patients in the ED. New strategies should be implemented to ameliorate crowded conditions and potential adverse outcomes.

Some subcutaneous foreign bodies (FBs) are not easily visualized during physical examination and may not be detected on radiographic evaluation. Ultrasound (US) is capable of visualizing FBs of varying compositions. Previous studies have examined the use of US to detect FBs in deceased animal or human tissue. This study used live anesthetized porcine tissue to more closely model clinical conditions. ⋯ Ultrasound was sensitive, specific, and accurate in identifying FBs in live anesthetized porcine tissue. Surrounding edema or hematoma 2 hours after placement was so infrequently observed that it was not possible to determine its influence on the test characteristics.

The incidence of cutaneous abscesses has increased markedly since the emergence of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA). Injection drug use is a risk factor for abscesses and may affect the microbiology and treatment of these infections. In a cohort of patients hospitalized with cutaneous abscesses in the era of CA-MRSA, the objectives were to compare the microbiology of abscesses between injection drug users and non-injection drug users and evaluate antibiotic therapy started in the emergency department (ED) in relation to microbiologic findings and national guideline treatment recommendations. ⋯ Compared with non-injection drug users, cutaneous abscesses in injection drug users were less likely to involve S. aureus, including MRSA, and more likely to involve streptococci and anaerobes; however, MRSA was common in both groups. Antibiotic regimens started in the ED were discordant with national guidelines in over half of cases and often lacked activity against MRSA when this pathogen was present.

The objective was to assess the relationship between emergency department (ED) admission rates for Medicare beneficiaries with chest pain and outcomes, specifically 30-day rates of acute myocardial infarction (AMI) and mortality. ⋯ Considerable variation exists across U.S. hospitals in ED admission rates for Medicare patients with chest pain. Hospitals that approach admissions more conservatively (i.e., higher admission rates) in this population have lower rates of AMI and mortality.
