Observational Study
Impact of a physician-in-triage process on resident education.
Emergency department (ED) crowding negatively impacts patient care quality and efficiency. To reduce crowding many EDs use a physician-in-triage (PIT) process. However, few studies have evaluated the effect of a PIT processes on resident education. Our objective was to determine the impact of a PIT process implementation on resident education within the ED of an academic medical center. ⋯ Implementation of a PIT process at an academic medical center was not associated with a negative (or positive) perceived impact on resident education. However, attendings and residents felt that differential diagnosis development was negatively impacted. Attendings also felt diagnostic test selection and medical decision-making learning were negatively impacted by the PIT process.

Case Reports
Ultrasound-guided diagnosis and aspiration of subdeltoid abscess from heroin injection.
A 49-year-old man presented to the emergency department (ED) with shoulder pain after intramuscular injection of heroin into his right deltoid muscle. Point-of-care (POC) ultrasound identified a subdeltoid abscess, and ultrasound-guided aspiration of the fluid collection was performed. The patient was admitted and improved on antibiotics and made a complete recovery. POC ultrasound and ultrasound-guided aspiration can assist in the diagnosis and treatment of deep musculoskeletal abscesses.

Multicenter Study
Availability and utilization of cardiac resuscitation centers.
The American Heart Association (AHA) recommends regionalized care following out-of-hospital cardiac arrest (OHCA) at cardiac resuscitation centers (CRCs). Key level 1 CRC criteria include 24/7 percutaneous coronary intervention (PCI) capability, therapeutic hypothermia capability, and annual volume of ≥40 patients resuscitated from OHCA. Our objective was to characterize the availability and utilization of resources relevant to post-cardiac arrest care, including level 1 CRCs in California. ⋯ Approximately 10% of hospitals met key criteria for AHA level 1 CRCs. These hospitals treated one-quarter of patients resuscitated from OHCA in 2011. The feasibility of regionalized care for OHCA requires detailed evaluation prior to widespread implementation.

Review Case Reports
Diphenhydramine overdose with intraventricular conduction delay treated with hypertonic sodium bicarbonate and i.v. lipid emulsion.
Diphenhydramine toxicity commonly manifests with antimuscarinic features, including dry mucous membranes, tachycardia, urinary retention, mydriasis, tachycardia, and encephalopathy. Severe toxicity can include seizures and intraventricular conduction delay. ⋯ The patient was ultimately treated with intravenous lipid emulsion therapy that was temporally associated with improvement in the QRS duration. We also review the current literature that supports lipid use in refractory diphenhydramine toxicity.

Shock index and prediction of traumatic hemorrhagic shock 28-day mortality: data from the DCLHb resuscitation clinical trials.
To assess the ability of the shock index (SI) to predict 28-day mortality in traumatic hemorrhagic shock patients treated in the diaspirin cross-linked hemoglobin (DCLHb) resuscitation clinical trials. ⋯ In these traumatic hemorrhagic shock patients, the shock index correlates with 28-day mortality, with higher SI values indicating greater mortality risk. Although DCLHb treatment did alter the distribution of SI values, it did not influence the ability of the SI to predict 28-day mortality.
