Comparative Study
Real-time B-mode ultrasound in the ED saves time in the diagnosis of deep vein thrombosis (DVT).
We hypothesize that EPs can decrease the time to disposition when performing examinations for deep venous thrombosis (DVT) compared with disposition times using imaging specialists (IS). We performed a prospective, single-blind observational study at an academic ED over the course of 1 year. Patients were enrolled based on study physician availability. ⋯ EPs and ISs had excellent agreement (kappa = 0.9). Compression ultrasound performed by EPs resulted in a significant decreased time to disposition. Agreement with ISs was excellent.

Comparative Study
Comparison of EPs' and psychiatrists' laboratory assessment of psychiatric patients.
EPs frequently transfer psychiatric patients to psychiatric hospitals with the approval and acceptance of a psychiatrist. EPs and psychiatrists have an unknown set of testing routines and requirements that are used to determine medical clearance of the psychiatric patient. The purpose of this study was to compare the routine and required testing performed by EPs as compared with psychiatrists. ⋯ It is unknown if the psychiatrists influenced the ordering behavior of the EPs. However, this study does demonstrate a difference in the routine test ordering, implying that these is a difference in the approach to the patient in the ED. Further means to obtain congruence in the testing protocol of psychiatric patients would be a valuable endeavor.

We studied the impact on triage and outcome of the presence of left ventricular hypertrophy (LVH) and left/right bundle branch block (LBBB/RBBB) on the initial ED electrocardiogram (ECG) for patients with symptoms suggestive of an acute coronary syndrome (ACS). Secondary analysis of data from a prospective clinical trial of patients with chest pain or other symptoms suggesting ACS in six U. S. hospitals comparing patient demographics, clinical variables, and outcomes was used. ⋯ Patients with ECG-LVH had approximately 3.5 times the 30-day mortality rate as those without these ECG abnormalities. It appears that for patients with symptoms suggestive of ACS, the presence of ECG-LVH or BBB did not alter the ability of ED clinicians to identify patients with ACS but was associated with a 50% higher false-positive admission rate compared with similar patients without these ECG abnormalities. With a short-term mortality rate 3.5 times that for patients without ECG-LVH, selected patients with ECG-LVH and symptoms suggesting ACS might benefit from hospitalization for further evaluation.

Hepatic portal venous gas (HPVG) is a rare radiographic finding of significance. Most cases with HPVG are related to mesenteric ischemia that have been associated with extended bowel necrosis and fatal outcome. With the help of computed tomography (CT) in early diagnosis of HPVG, the clinical outcome of patients with mesenteric ischemia has improved. ⋯ Patients with radiographic diagnosis of HPVG should receive a detailed history review and physical examination. The patient's underlying condition should be determined to provide a solid ground for exploratory laparotomy. A flow chart is presented for facilitating the management of patients with HPVG in the ED.
