Randomized Controlled Trial Comparative Study Clinical Trial
Provision of clinically based information improves patients' perceived length of stay and satisfaction with EP.
We conducted a focused, prospective, randomized study to evaluate whether periodic personal provision of clinically based information to patients during an Emergency Department (ED) visit improves patients' perceptions of physician's excellence and efficiency of patient care. Six hundred nineteen consecutive adult patients or proxy informants, who were evaluated in the ED and subsequently discharged, were randomized into the standard of care (n = 307) and intervention group (n = 312). Under supervision by ED attending physicians, a single research assistant periodically provided patients with process and medical information at 15-minute intervals, starting at arrival and continuing through until discharged from the ED. ⋯ Patients' perception of nursing skills were, however, statistically similar in the 2 groups (Bedside: 83.1% vs. 83.0%, P =.942; Technical skill: 84.5% vs. 82.7%, P =.613). Given the sample size and observed proportions, the chi(2) analysis of perception of nursing skill had a power of 4.8% (registered nurse [RN] bedside) and 7.5% (RN technical skill). Periodic personal interaction and provision of clinically based information in the ED is thought to improve patients' perceived LOS, efficiency, and clinical skills of EP after an ED visit.

Computed tomography has had a questionable role in diagnosing blunt aortic injury (BAI). The objective of this study was to determine the effectiveness of helical computed tomography of the thorax (HCTT) for detection of BAI. Trauma Registry data and medical records were reviewed for 2,854 patients admitted over a 32-month period. ⋯ HCTT effectively screens for BAI. Aortography can be more specifically applied as a diagnostic study when preceded by HCTT. HCTT should not be used as solitary study for BAI as some injuries identified by HCTT do not represent BAI.

Randomized Controlled Trial Comparative Study Clinical Trial
Subcutaneous lidocaine delivered by jet-injector for pain control before IV catheterization in the ED: the patients' perception and preference.
To evaluate patients' perceptions and preferences concerning pain control during intravenous (IV) catheterization, a sample of 50 adult patients received subcutaneous lidocaine (0.2 mL 1%) by jet injector, or no anesthetic with a sham injection before IV catheterization. Visual analog scale (VAS), pain intensity score (PIS), and adverse reactions were recorded. ⋯ Patients in both groups (84% overall) preferred local anesthesia based on this experience. Using the jet-injector to provide local anesthesia before IV catheterization in the ED is effective, fast, and does not require sharps disposal and handling precautions.

Comparative Study
Prevalence of orthostatic hypotension among patients presenting with syncope in the ED.
We sought to determine the prevalence of orthostatic hypotension as a cause of syncope in the emergency setting, and describe the characteristics of patients diagnosed with this condition. Blood pressure orthostatic changes were measured prospectively in a standardized fashion up to 10 minutes, or until symptoms occurred, in all consecutive patients with syncope as a chief complaint presenting in the emergency department (ED) of a primary and tertiary care hospital. Patients unable to stand-up were excluded. ⋯ Compared with patients with vasovagal disorder, those with orthostatic hypotension were older; had more comorbid conditions including hypertension, organic heart disease, and abnormal electrocardiogram; were taking more hypotensive medications; and required more frequently hospitalization (P <.01). We concluded that standardized blood pressure measurement in the ED enabled to strongly implicate orthostatic hypotension as a cause of syncope in 24% of patients with this symptom. Drug-related hypotension was the most frequent cause for this disorder.

Comparative Study
Painful discrimination: the differential use of analgesia in isolated lower limb injuries.
Our primary objective was to compare use of analgesia for patients with and without fracture as a result of isolated lower extremity trauma, in the emergency department (ED). Our secondary objective was to compare the analgesic practices of emergency physicians (EPs) with that of physician assistants (PAs). We performed a prospective, blinded cohort study with the presence of fracture as the risk factor and provision of any pain medication while in the ED as the primary outcome. ⋯ Our estimated adjusted ORs for providing analgesia in the ED were: fracture = 2.0 (CI 95% 1.13, 3.58); EP: 3.52 (CI 95% 1.98, 2.99); and for every additional point on the verbal pain scale: 1.28 (CI 95% 1.11, 1.48). Patients with fracture were more likely to receive pain, despite reporting identical degree of pain. EPs were more likely to provide analgesia than PAs.
