The medical records of 109 patients who presented to the emergency department during a five-year period with proven nontraumatic, spontaneous subarachnoid hemorrhage (SAH) were retrospectively reviewed. The clinical presentation, diagnostic modalities used, and accuracy of diagnosis by emergency physicians were analyzed. The most common historical features were headache (81 patients, or 74%), nausea or vomiting (85 patients, or 77%), and loss of consciousness (58 patients, or 53%). ⋯ The overall diagnostic accuracy by emergency physicians was 85%. The correct diagnosis was delayed in 16 patients (15%), the majority of whom had headaches and normal neurologic examinations. Atypical symptoms, the warning leak syndrome, and the need for prompt diagnosis and therapy are reviewed.

Comparative Study
A follow-up report of occupational stress in urban EMT-paramedics.
A survey completed by 280 nonvolunteer, urban emergency medicine technician (EMT)-paramedics revealed high levels of occupational stress. We used a four-component model of occupational stress in medical environments to show indications that much variation in the manifestation of stress was accounted for by the rank and job description of the EMT-paramedic, the district served by the EMT-paramedic, and the patient population served by the EMT-paramedic. Stress exhibited by field EMT-paramedics tended to manifest in more negative attitudes toward patients, whereas administrative-level paramedics exhibited more organizational stress. ⋯ Special attempts should be made to identify and counsel EMT-paramedics who are undergoing stressful life events. Finally, we suggest that rotating EMT-paramedics through various districts on a regular basis may help alleviate the negative impact on patient care in areas that have been identified as particularly stressful. Further studies are needed to verify our hypothesis.

Comparative Study
The effect of urban trauma system hospital bypass on prehospital transport times and Level 1 trauma patient survival.
We studied the influence of hospital bypass on prehospital times and Level 1 trauma patient survival. During the nine-month study period, 251 Level 1 trauma patients were transported to the Cook County Hospital trauma unit by Chicago Fire Department (CFD) paramedics. The prehospital times and survival rates in the 203 (81%) patients who arrived with vital signs were analyzed. ⋯ Survival was 86% in the bypass group and 85% in the direct group. The elapsed time between the injury and CFD contact (delay time) averaged 27 +/- 26 minutes and contributed 43% to the 63-minute mean overall time from the injury event to arrival at the trauma center. Total run time in directly transported patients accounted for 52% of the mean overall prehospital time.(ABSTRACT TRUNCATED AT 250 WORDS)

Comparative Study
Evaluation of the validity of the Done nomogram in the management of acute salicylate intoxication.
To evaluate the validity of the Done nomogram in the management of acute adult salicylate intoxications, a retrospective review of cases at our institution was performed. The degree of severity (ie, asymptomatic, mild, moderate, or severe) as determined by plotting the serum concentration and time on the nomogram for 55 acute salicylate intoxications was compared with the degree of severity decided on by three experienced emergency physicians who based their decision on the clinical presentation of the cases and the original criteria devised by Done for each category of severity. Discordant classifications between the nomogram and the physicians provided a basis on which a predictive index for the nomogram and various subsets of cases could be determined. ⋯ The nomogram tends to overpredict the severity of intoxication in the moderate and severe categories. There was no significant difference between predictive indexes of mixed versus nonmixed or enteric-coated acetylsalicylic acid versus plain acetylsalicylic acid cases, although the nomogram had a higher predictive index when used for concentrations drawn six to 12 hours after ingestion (P less than .01, Fisher's exact test). Decisions on management of an acute salicylate overdose should be based on clinical presentation and good judgment as well as the serum salicylate concentration in relation to the time of ingestion.

A review of autopsy reports on traumatic deaths in 1986 was conducted to determine the impact on trauma mortality of the regionalized trauma system instituted in San Diego County in 1984. Determination of preventable death was made by a panel of experts and compared with an identical review of traumatic deaths in 1979, five years before the institution of regionalized trauma care. Of 211 traumatic deaths reviewed from 1986, two (1%) were classified as preventable, compared with 20 of 177 (11.4%) deaths in 1979 (P less than .001). ⋯ The decrease in central nervous system-related preventable deaths from four of 94 in 1979 to one of 149 in 1986 (P less than .10) was not statistically significant. Although it is likely the trauma system introduced in 1984 contributed to the decline in preventable death, it is not possible to isolate this variable from other changes that occurred during the interval between studies. A review of trauma deaths over the same time interval in a community with similar demographics but without a trauma system might help determine the relative contribution of the trauma system.
