Assaults from penetrating trauma in the State of Illinois.

This study was undertaken to evaluate the incidence, epidemiology, and temporal relationships of assaults in the State of Illinois from penetrating trauma presenting to Level I and Level II trauma centers, and to project the impact of these variables on hospital staffing. A retrospective analysis was performed on 4 months of data (7/1/92 to 10/31/92) provided by the Illinois Department of Public Health describing consecutive assaults with firearms or knives presenting to all Level I and Level II trauma facilities in the State of Illinois. Data were analyzed for epidemiological parameters including age, gender, and race. Other variables analyzed included trauma score, Glasgow Coma Scale (GCS) score, ethanol levels, urine toxicology results, and mortality. The data were also analyzed for temporal patterns of hospital presentations with respect to the time of day and day of the week. A total of 1,288 cases of penetrating wounds were analyzed. Of these, 881 (68.4%) resulted from firearms and 407 (31.6%) resulted from stab wounds. Ages of all penetrating trauma victims ranged from less than 1 year to 84 years of age. The mean age for firearm victims was 25.0 +/- 10.8 (SD) years and 30.5 +/- 11.4 years for stabbing victims. Ninety percent of penetrating trauma victims were male and 10% were female. Seventy-two percent of the victims were African-American, 13% Hispanic, 13% Caucasian, and 2% other. Alcohol levels were available for 727 of the 1,288 (56.4%) patients. Of these 727, 433 (59.6%) had measurable levels. The results of drug screens were available for 582 of the 1,288 (45.1%) victims. Of these 582, 208 (35.7%) were positive. Other than alcohol, cocaine was the most frequently detected drug, accounting for 58.4% of the positive drug screens. Firearm victims had significantly lower trauma scores (10.5 v 11.2) and GCS scores (13.2 v 14.3) than stab victims. Significant circadian patterns of penetrating trauma were observed for both types of assaults. For assaults with firearms, the circadian rhythm peaked at 23.1 +/- 0.36 hours. For assaults with knives, the circadian rhythm peaked at 23.7 +/- 0.44 hours. Weekly patterns were not statistically significant for each individual type of assault. However, when the data were pooled, a weekly pattern peaking on Thursday was observed. These patterns of presentation for assaults are a significant finding that may have implications for hospital staff scheduling of trauma center physicians, nurses, technicians, security, social service, and other ancillary staff.

Analysis of cocaine chronotoxicology in an urban ED.

To describe the chronotoxicology of cocaine and its potential impact on emergency department (ED) staffing and services, Drug Abuse Warning Network (DAWN) data from a single urban university ED were retrospectively reviewed. The DAWN data reviewed spanned an 11-year period (1/1/83 through 12/31/93), and 3,762 patients were enrolled. Patients were included if the ED records included documentation of recent cocaine abuse prior to presentation to the ED. Of the 3,762 study patients, 1,609 (43%) had documentation of recent cocaine use: 506 (32%) had used cocaine alone, 614 (38%) had used cocaine and ethanol in combination, and 489 (30%) had used cocaine in combination with other drugs. For all patients using cocaine, there were two significant rhythms (P < .05) identified: a circadian rhythm that peaked at 1800 and a 12-hour rhythm that peaked at approximately noon and midnight. A significant rhythmicity was found among cocaine-using patients who presented during the study period. Increased or shift-adjusted staffing focusing specifically on psychosocial services, detoxification, and security during these peak hours may provide more efficient emergent care for this subpopulation of patients.

Denial of emergency department authorization of potentially high-risk patients by managed care.

This study was designed to evaluate patients presenting to a large urban university emergency department (ED) who were subsequently denied authorization for reimbursed care by their managed care provider and to characterize the denial as potentially safe or unsafe based on published triage criteria. A consecutive case surveillance was performed from October 1, 1994 to September 30, 1995 at a university-based ED (30,000 visits per year) for adult patients in inner-city Chicago. Cases were comprised of adult managed care participants whose providers refused by telephone to authorize payment for ED services and who then left the ED without treatment. Chief complaints and vital signs were used to categorize patients as high-risk or nonemergent based on previously published criteria. A total of 2,965 adult managed care patients presented to the ED during the study period, representing 11.1% of the total ED census. Of these patients, 244 (8.2%) were denied authorization for payment of their care. By previously established criteria, 115 (47.1%) were identified as potentially unstable, 61 (53%) due to abnormal vital signs and 54 (47%) with other high-risk indications such as severe pain, chest pain, or abdominal pain. These potentially high-risk patients may subsequently suffer adverse outcomes. Current guidelines used for telephone triage by managed care to divert patients from our ED do not meet previously published safe triage criteria.

Stress in the emergency department clerical staff.

Clerical staff are vital for the effective management of the emergency department. A survey of emergency department clerks was conducted to determine the prevalence and types of stress in their jobs. Forty-six of fifty surveys were completed and returned. Seventy-six percent of the respondents rated their job in the "extremely stressful" range. Stress was a factor responsible for job absenteeism in 24% of the respondents. Most agreed that physician education is necessary.

Atheromatous embolism: an unusual case of acute lower extremity ischemia.

A case is presented of lower extremity ischemia related to atheromatous embolization that presumably occurred as a result of passage of an angiographic catheter through the aorta. The patient presented with signs and symptoms pathognomonic for this entity. Emergency physicians need to be aware of this unusual etiology for an ischemic lower extremity.

Driving under the influence--a level-I trauma center's experience.

Alcohol-impaired driving is a major issue confronting today's society. New legislation is emerging to help curtail this ongoing problem. To evaluate the legislative effects in terms of outcome pertaining to injured drivers, we analyzed the records of 116 consecutive motor vehicle drivers who were admitted to our trauma center over a 16-month period. Medical reports, police reports, and drivers' abstracts were reviewed. Of the 116 drives, 61 (53%) had blood alcohol concentrations that exceeded the legal limit (blood alcohol level greater than or equal to 100 mg/dL) on arrival at the emergency department. Only four of these patients were ticketed for driving under the influence and received the mandatory suspension of their driver's license. None was convicted of this offense, which carries criminal charges and a revocation of the driver's license. Mechanisms for efficient collection of blood specimens and mandatory occurrence reporting are two recommendations that merit investigation to obviate further escape of injured, intoxicated drivers from the legal net. In addition, alcohol rehabilitation and education cannot be overlooked and should warrant strong societal support.

A review of prehospital care litigation in a large metropolitan EMS system.

A retrospective review of all claims brought against a large, metropolitan emergency medical services (EMS) system related to paramedic-patient encounters during the 12-year period from 1976 through 1987 was undertaken to review and describe the incidence and types of malpractice claims. During this period, EMS units responded to approximately 2 million calls and transported more than 1 million patients. Sixty claims occurred during the incidence study period (1976 through 1985). The overall litigation rate was one lawsuit per 27,371 paramedic-patient encounters and one lawsuit per 17,995 patient transports. While the total number of runs and transports did not change significantly during the study period, the data indicate a trend of increasing claims filed against the prehospital care provider. To date, 26 cases (38%) have been settled with the majority involving either no monetary awards or nominal out-of-court settlements.

Paramedic skill decay.

To determine the amount of skill deterioration in paramedics, 40 graduates from three consecutive classes of Chicago City-Wide Paramedic training programs were tested. Examinations consisted of the practical aspects of airway management, spinal immobilization, and intravenous fluid therapy identical to their school final examination. As a group, study scores were significantly lower than graduation scores. However, in only two areas were there individuals performing below acceptable levels. These were in spinal immobilization with extrication and extremity immobilization. The continuing education and recertification process need to develop reliable methods to identify and then correct deficiencies in performance levels of system participants.

Chinese restaurant syndrome: a review.

CRS is a benign, self-limited process that has an excellent prognosis for immediate and rapid recovery. While questions remain about exactly who is susceptible, how much MSG is needed, and even whether MSG is the sole etiologic agent, there appears to be little reason to embark on an extensive workup and treatment regimen with a presumptive diagnosis of MSG intoxication. Rather, knowledge of CRS and recognition of its associated signs and symptoms and its clinical course are important.
