Multicenter Study
Use of physician extenders and fast tracks in United States emergency departments.
To describe current practice regarding the use of physician extenders (PEs) and the "fast track" (FT) concept in United States emergency departments (EDs), a telephone survey of 250 US health care facilities offering emergency services was conducted. Of the EDs surveyed, 21.6% were using PEs at the time of the survey, and of those not using PEs, 23.5% intended to do so within the next 2 years. Those using PEs had been using them for a mean duration of 3.5 years (the mode was 2 years). ⋯ The mean estimated percentage of ED patients going through FT was 30.1%. The mean number of hours per day of FT operation was 13.4 hours on weekdays and 13.7 hours on weekends (the mode was 12 hours/day both on weekdays and weekends). Of hospitals using PEs in the ED, 56.0% had FT; of hospitals without PEs in the ED, 23.5% had FT.

Acute traumatic aortic injury (ATAI) results in several characteristic chest radiographic findings, most notably mediastinal widening. This study was based on the hypothesis that blood or fluid in the widened mediastinum might track up into the neck and be detected on lateral cervical radiographs. In a blinded, retrospective, case-control review of radiology files, 13 consecutive adult cases of ATAI were identified and compared with 19 cases of negative aortography (NAO) and 18 multiple trauma victims (MT) without aortography. ⋯ Cervical ST measurements at C3 or at C6 did not correlate with mediastinal-chest width ratios. Mediastinal widening, aortopulmonic window opacification, and blurring of the aortic knob were the most sensitive chest radiography findings in ATAI, although each of these lacked useful specificity and accuracy. Cervical ST swelling is not a useful marker for ATAI.

A study was undertaken to determine if there are differences in hematocrit (HCT) during the initial evaluation of patients with and without significant visceral intrathoracic or intraabdominal injury after penetrating trauma and, if so, the predictive value of this parameter. Sixty consecutive adults with potentially significant penetrating trauma who presented to an urban municipal trauma center during a 10-week period were studied. Diagnostic variables were recorded for all patients at risk for significant injury, defined as intrathoracic or intraabdominal injury requiring surgical intervention. ⋯ Presentation with an HCT below normal, or an early decrease in HCT, is an indicator of potential injury. Although many patients with serious internal injuries do not manifest large decreases early after presentation, those who do have a high probability of internal injury. The lower the HCT, or the greater the decrease, the greater the probability that a significant injury exists.

Occult infections during sickle cell pain crisis can be associated with significant morbidity. It has been suggested that empiric workup for pneumonia and urinary tract infection (UTI) is required. A study was undertaken to determine whether clinical criteria can be used to exclude such infections as precipitants of pain crisis in adults. ⋯ In patients with sickle cell pain crisis, medical history and physical examination can be useful to predict the absence of pneumonia, but may not be as beneficial in predicting the absence of UTI. These results suggest that empiric chest x-ray may be unnecessary to exclude pneumonia; however, routine urinalysis may be indicated. Because of the low incidence of these infections, larger studies are required to confirm these findings.

A study was conducted to determine parameters indicating the current use of computed tomography (CT) in the emergency department (ED). Computerized data regarding patients seen in the ED between 1/1/92 and 9/30/95 were retrieved. A rate of 36/1,000 patients underwent CT in the ED (ED CT). ⋯ Some parameters about the use of ED CT were identified. The information obtained will allow comparison of practice between EDs in different medical centers and will be useful to hospital administrators, health planners, and clinicians. This retrospective analysis is to be followed by more comprehensive prospective studies involving different EDs in various sections of the country.
