To determine if out-of-hospital emergency medical services (EMS) time intervals are associated with unexpected survival and death in urban major trauma, a retrospective review was conducted of major trauma cases entered into an urban trauma system by an EMS system during a one-year period. Patients with unexpected death or unexpected survival were identified using TRISS methodology. The EMS response, on-scene time, transport time, and total EMS out-of-hospital time intervals were compared for the two groups using the unpaired t test (two-tailed analysis). ⋯ The mean EMS on-scene time interval (7.8 +/- 4.1 minutes v 11.6 +/- 6.5 minutes; P = .06) and the mean transport time interval (9.5 +/- 4.4 minutes v 11.7 +/- 4.0 minutes; P = .17) also favored the unexpected survivor group. Overall, the total EMS time interval was significantly shorter for unexpected survivors (20.8 +/- 5.2 minutes v 29.3 +/- 12.4 minutes; P = .02). It was concluded that a short overall out-of-hospital time interval may positively affect patient survival in selected urban major trauma patients.

A prospective study was performed to determine acuity levels, waiting times, and reasons why patients who sought care in an emergency department (ED) left without being seen by a physician, and to evaluate whether timed telephone follow-up improved their health outcomes. A comparison and follow-up survey was conducted on all patients who registered for care in the ED at the Naval Medical Center, San Diego, CA, and left without being seen (n = 32) and a 20% systematic sampling of patients who waited until they were seen (n = 170) during a one-week period in Spring, 1993. Baseline demographics and health statuses on reporting to the ED were gathered on all patients waiting to be seen that agreed to participate in the study (n = 533). ⋯ Acuity levels were compared for patients seen versus LWBS for level I (1.5% v 3%, NS), level II (75% v 78%, NS), and level III (23.5% v 19%, NS). For the 25% that left before triage, level I was 9%, level II was 64%, and level III was 27%. Sixty-nine percent of patients who LWBS were seen for evaluation within 48 hours, 9% in an ED and 60% in a clinic.(ABSTRACT TRUNCATED AT 250 WORDS)

To determine the sensitivity of an emergency physician's conventional evaluation compared with the validated Confusion Assessment Method (CAM) regarding the recognition of acute confusional states (delirium) in elderly Emergency Department (ED) patients, a cohort of 385 patients presenting to an urban teaching hospital ED was systematically assembled. Patients had to be conscious, able to speak and older than 64 years of age. After the ED physician had examined the patient and test results had been obtained, a series of geriatric assessment results, including one for the likely presence of delirium, was made available to the ED physician; however, no result was specifically highlighted. ⋯ The ED diagnosis included delirium or an acceptable synonym in 6 (17%) of these patients. In the 21 patients (62%) admitted to the hospital, the most common ED diagnosis was infection "rule out sepsis" (n = 7). Six of 13 patients discharged (46%) were diagnosed as "status post fall" without evidence of significant injury.(ABSTRACT TRUNCATED AT 250 WORDS)

Previous research at the Division of Air Medical Services at East Carolina University School of Medicine has demonstrated impairment of chest compression efficacy in the setting of an airborne BO-105 helicopter. This study was undertaken to determine whether in-flight compression efficacy could be improved with utilization of a pressure-sensing monitor providing real-time feedback during cardiopulmonary resuscitation (CPR). ⋯ The mean proportion of correct compressions (95.7 +/- 3.2%) achieved with utilization of the pressure-sensing monitor was significantly higher (P < .01) than the corresponding proportion for the control group (33.4 +/- 12.1%). This study demonstrated that the difficulties of performing effective in-flight chest compressions are largely overcome with utilization of a pressure-sensing device providing real-time feedback on compression efficacy.

The diagnosis and monitoring of patients presenting to an emergency department with blunt temporal bone fracture and complications requiring acute management were reviewed for a four-month period. Of 104 trauma patients with closed head injury, 15 patients were diagnosed with temporal bone fracture, 12 of whom survived their injuries. Four patients developed cerebrospinal fluid (CSF) otorrhea and two patients developed facial nerve paralysis; all patients had resolution of complications with conservative management. ⋯ Specific and thorough facial nerve examinations were not initially conducted on temporal bone fracture patients and subsequent inpatient monitoring for facial nerve paralysis and CSF otorrhea was incomplete. The outcome of temporal bone fracture is discussed. This article reminds the emergency physician of the importance of initial diagnosis and documentation of temporal bone fractures.
