Comparative Study
The role of an emergency department observation unit in the management of trauma patients.
During a 12-month period, 20,838 patients with acute traumatic injuries were seen in the Emergency Department (ED) of Denver General Hospital. Of these patients, 520 (2.5%) were admitted to the ED Observation Unit, a seven-bed acute care unit situated within the ED and sufficient data were available on 485 (93%) for inclusion into the study. Fifty-three (15.4%) of these observation unit patients required subsequent admission, 389 (80%) were discharged, and 16 (4%) left against medical advice. ⋯ These groups of patients were analyzed and compared with regard to severity of injury, length of stay, and discharge diagnosis. The observation unit is useful in the evaluation of blunt chest or abdominal trauma when work-up, including chest x-ray studies and peritoneal lavage, is initially negative and when drug or alcohol ingestion obscures the initial evaluation in the ED. An observation unit within the ED is cost-efficient and has proven very useful in the management of trauma victims.

The management in the emergency department of febrile infants less than 2 months of age is influenced by the standard of practice in the community. We sought to determine if uniform practices existed across the United States. Individual academically based faculty from 154 (61%) United States pediatric residency programs responding to a questionnaire on the emergency department management of febrile infants less than 2 months of age showed great variability. ⋯ Respondents differed on the number and types of tests used and on antibiotic administration. University affiliation, type of population served, or presence of advanced training programs in ambulatory pediatrics were not related to the type of policy. The care of the young febrile infant varies greatly.

Acute otitis media is a common pediatric infection that requires appropriate evaluation of the young child to assure that there are no accompanying systemic infections or complications. The examination of the ear must not only assess the appearance of the tympanic membrane, but determine its mobility. Treatment should be initiated with antibiotics and symptomatic relief. Good follow-up must be arranged.
