Emergency medical planning for the 2000 Republican National Convention.

Planning for emergency medical services (EMS) coverage for the 2000 Republican National Convention in Philadelphia was a complex process that involved the cooperation of municipal, state, and federal agencies as well as local hospitals. The medical needs of the delegates, members of the media, and support personnel at the convention venue had to be met. Contingency plans for the possibility of large, organized political protests and associated injuries had to be developed. Steps had to be taken to ensure the safety of emergency personnel who may have to respond to such incidents. Because of the heightened threat of terrorist attacks on civilian populations in recent years, specialized training and material to respond to such incidents were required. The important role that local hospitals may play in providing care to victims of a large, multicasualty incident, especially one involving weapons of mass destruction, was recognized. Therefore, steps were taken to increase the awareness of hospital staff to patient decontamination and isolation techniques as well as specific therapies for the chemical, biological, and radioactive agents that terrorists might use. Finally, despite the focus placed on the convention, the day-to-day emergency medical needs of the citizens of Philadelphia had to be met. Through careful planning, flexibility, and cooperation, it was possible to successfully address all of these issues.

Declining rate of substance abuse throughout the month.

PURPOSE: The timing of federal disbursements of welfare, disability, and military benefits may be associated with monthly patterns of substance abuse. We assessed whether this association was reflected in the pattern of psychiatric presentations to an emergency room. SUBJECTS AND METHODS: We conducted a retrospective, case-control study of 12,904 patient presentations to an urban emergency department for psychiatric reasons during a 7-year period. Cases were defined as patients (n = 2,403) given a primary diagnosis of substance abuse. Controls included patients (n = 10,501) with a primary diagnosis of another psychiatric illness. We calculated the "boundary effect" (R = 100 times the number of presentations during the first week of the month divided by number of presentations during the last week of the preceding month) for each month, and averaged these values across months to determine overall effects. RESULTS: The boundary effect was stronger for patients with primary substance abuse disorders (R = 134, 95% confidence interval [CI] = 118 to 151) than for patients with other psychiatric disorders (R = 106, 95% CI = 100 to 112; P < 0.001). Weekly presentations for substance abuse declined consistently throughout the month (P = 0.01), and declined significantly more than the incidence of other psychiatric presentations (P = 0.005). These effects remained, after adjusting for fluctuations in presentations around holidays and the new year. The lunar cycle did not influence the incidence of presentations. CONCLUSION: Our results confirm that substance-related morbidity is highest at the beginning of the month and declines thereafter, corresponding to the availability of disposable income from monthly checks.

Short-term outcome of seizure patients who refuse transport after out-of-hospital evaluation.

OBJECTIVE: To determine the short-term outcome of patients with a known seizure disorder who have a seizure, are evaluated by out-of-hospital care providers, and refuse transport. METHODS: This was a prospective study conducted over a 15-month period. Philadelphia Fire Department paramedics contacted a medical command physician whenever they encountered a patient with a known seizure disorder who had had another seizure and was refusing transport. After confirming that the patient had the mental capacity to refuse care and understood the associated risks, the physician recorded the patient's name, address, and telephone number. Beginning three days later, a registered nurse attempted to reach the patient by telephone and administer a brief questionnaire about his or her medical outcome. Patients not reached by telephone were sent a certified letter. The names of patients lost to follow-up were compared with medical examiner records to confirm that they had not died during the follow-up period. RESULTS: Of 63 patients enrolled in the study, 52 (82.5%) were reached in follow-up. Of these, three (5.8%) had another seizure within 72 hours and recontacted 911. One of these patients (1.9%) was hospitalized. Twenty (38.5%) patients contacted their primary care physicians. There were no deaths, including patients lost to follow-up. CONCLUSIONS: Most patients (94.2%) who were evaluated by out-of-hospital care providers for a seizure and refused transport had no further seizure activity in the subsequent 72 hours. However, because there is a risk of recurrence, out-of-hospital care providers and medical command physicians should ensure that patients understand the risks of refusal.

Violence between women in an urban emergency department patient population.

OBJECTIVE: To determine what percentage of women presenting to an urban emergency department (ED) for any reason had been the victims of violence committed by another woman in the previous year. METHODS: This was a prospective study of a consecutive sample of female patients of legal age presenting to the ED between 8 AM and 12 midnight over an 11-week period. Patients were asked a series of questions adapted from the George Washington University Universal Violence Prevention Screening Protocol. Non-English-speaking patients, those unable to give informed consent, and those meeting regional criteria for major trauma were excluded. RESULTS: One thousand six hundred seventy-six women participated; 426 (25%) refused. Of the 1,250 women interviewed, 118 (9.4%; 95% CI = 7.8% to 11.1%) reported being assaulted by another woman in the previous 12 months. Compared with the nonvictims, the victims were more frequently younger and single. The most common forms of assault were slapping, grabbing, and shoving (54.7% of victims). These were followed by being choked, kicked, bitten, or punched (46.2%). Eighteen percent of the assaults involved a weapon or an object. Five percent of the victims described being forced to have sex. Thirty-seven percent of the victims contacted the police, 13% required medical attention, 17% pursued legal action, and 10% sought follow-up counseling. CONCLUSIONS: Nine percent of the women in the study sample had been assaulted by another woman in the previous year. Further attention to the recognition and management of violence committed by women against other women may be warranted to ensure that patients receive appropriate treatment and referral.

Utilization of the 911 system as an identifier of domestic violence.

This cross-sectional study was performed to determine (1) whether female victims of domestic violence (DV) are more likely to use the 911 system than nonvictims (NVs) and (2) whether DV and NVs call 911 for different reasons so that 911 may be used as a screening tool for abuse. The study was performed in an academic adult urban emergency department (ED). Ambulatory female patients presenting to the ED were studied. Eligible patients were administered a brief survey by trained research assistants. Questions included (1) history of DV, (2) relationship of assailant to victim, (3) chief complaint, and (4) use of the 911 system. Records of 911 calls were obtained by patient's address. Four hundred sixty-one women were enrolled in the study. One hundred seven (23%) reported a history of DV. Intimate partners accounted for 67.2% of assailants. DV victims were more likely to be single and younger (P < .05). Of DV victims, 77% reported calling 911 for any reason in the past 2 years compared with 47% of nonvictims (difference = 30%; 95% CI, 19%, 40%). DV victims were more likely to call 911 than nonvictims for definite and possible cases of domestic dispute (1.4 v0.5 calls, P = .007; 11.7 v6.1 calls, P = .0003). Victims and nonvictims did not differ in the number of nondomestic dispute calls (8.4 v6.2 calls; P = .15). DV victims were more likely to access the 911 system and call for domestic disturbances compared with nonvictims. 911 calls may serve as an indicator of ongoing abuse and may identify women at risk, providing a potential opportunity for intervention.

History of domestic violence among male patients presenting to an urban emergency department.

OBJECTIVE: To establish the prevalence of domestic violence committed by women against male patients presenting to an urban ED for any reason. METHODS: This was a prospective survey in which male patients of legal age presenting to the ED over a 13-week period were interviewed. Patients answered a series of six questions adapted from the George Washington University Universal Violence Prevention Screening Protocol. Patients who could not speak English, those refusing to participate, those unable to give informed consent, and those meeting regional criteria for major trauma were excluded. RESULTS: Of 866 male patients interviewed, 109 (12.6%) had been the victims of domestic violence committed by a female intimate partner within the preceding year. Victims were more likely to be younger, single, African American, and uninsured. The most common forms of assault were slapping, grabbing, and shoving (60.6% of victims). These were followed by choking, kicking, biting, and punching (48.6%), or throwing an object at the victim (46.8%). Thirty-seven percent of cases involved a weapon. Seven percent of victims described being forced to have sex. Nineteen percent of victims contacted the police; 14% required medical attention; 11% pressed charges or sought a restraining order; and 6% pursued follow-up counseling. CONCLUSIONS: Almost 13% of men in this sample population had been victims of domestic violence committed by a female intimate partner within the previous year. Further attention to the recognition and management of domestic violence committed by women against men may be warranted.

The effectiveness of midazolam as a single pharmacologic agent to facilitate endotracheal intubation by paramedics.

OBJECTIVE: Endotracheal intubation (ETI) remains the "gold standard" for securing a patient's airway. In recent years, the use of pharmacologic agents to assist paramedics achieve successful intubation of problematic airways has become more common. This study was done to determine the efficacy of intravenous midazolam, a short-acting benzodiazepine, as a drug to facilitate intubation in patients resistant to conventional ETI. METHODS: This retrospective observational study reviewed the 22-month experience of a suburban municipal EMS system after midazolam was introduced as an agent to be used for systemic sedation to facilitate ETI. All calls where midazolam was used were reviewed on a monthly basis by investigators via retrospective review of the prehospital care reports. RESULTS: During the study period 13,212 emergency responses occurred, resulting in 154 ETIs by paramedics. Midazolam was used to facilitate 20 (13%) of these ETIs. "Clenched teeth" and failed conventional intubation were the most commonly cited indications for facilitated intubation. Eleven patients had medical complaints and nine were trauma patients. Successful ETI with midazolam was achieved in 17 of 20 (85%) cases. In 85% (15 of 17) of these cases, a single dose of midazolam was sufficient for ETI [mean dose 3.6 mg (SD 1.1 mg)]. The three patients with failed ETI received multiple doses of midazolam [mean dose 5.0 mg (SD 2.0 mg)]. CONCLUSION: The prehospital use of single-dose IV midazolam is generally effective in accomplishing facilitated ETI in patients resistant to conventional (nonpharmacologic) ETI.

The short-term outcome of hypoglycemic diabetic patients who refuse ambulance transport after out-of-hospital therapy.

OBJECTIVE: To determine the short-term medical outcome of hypoglycemic insulin-dependent diabetic patients who refuse transport after out-of-hospital therapy and return to baseline mental status. METHODS: Prospective, descriptive, short-term medical outcome data for adult patients were collected between May 1996 and December 1996. Paramedics responding to the aid of hypoglycemic insulin-dependent diabetic patients who refused transport after administration of dextrose solution (D50W) contacted a medical command physician at the University of Pennsylvania. The patients' medical histories, names, addresses, and telephone numbers were recorded. Three days after their hypoglycemic episodes, these patients were contacted by telephone by a registered nurse to determine their medical conditions. RESULTS: Of 132 patients enrolled in the study, 103 (78%) could be contacted by telephone follow-up. Ninety-four (91%) of these patients had no recurrence of symptoms. Nine patients (9%) had recurrence of hypoglycemia and recontacted 911. Eight of these (8%) were transported to a hospital via ambulance and 3 (3%) were admitted, 1 (1%) for a cancer-related illness and 2 (2%) for hypoglycemia, 1 of whom died (1%). The remaining patient refused transport a second time after being treated, despite having the risks of refusal explained to him by a medical command physician. CONCLUSIONS: The practice of treating and releasing most hypoglycemic insulin-dependent diabetic patients who return to normal mental status after D50W administration appears in general to be safe. Patients should be advised of the risks of recurrent hypoglycemia.

Delayed cardiac tamponade in a patient with penetrating chest trauma.

We describe a case of cardiac tamponade due to pulmonary artery laceration as a late sequela in a patient who had sustained penetrating chest trauma. A 35-yr-old man presented to our emergency department complaining of pleuritic left chest pain, shortness of breath, and fever 19 days after being hospitalized for a stab wound to the left chest. During his first hospitalization, chest X-ray study, echocardiogram, and central venous pressure determination were all normal. On second presentation, he had a cardiac tamponade and underwent a median sternotomy. A pulmonary artery laceration was discovered and repaired. The postoperative course was complicated by readmission for postcardiotomy syndrome. This case demonstrates that late and unexpected complications can occur in patients with penetrating chest trauma and a normal initial evaluation.

Wound botulism.

All published cases of wound botulism were reviewed to describe the epidemiology, clinical manifestations, diagnosis, and treatment of this rare infection. The MEDLINE data base of English-language literature was searched from 1966 to 1992, using the keywords "wound botulism". Cases published during this period were identified, and the bibliographies of these articles were used to identify cases published before MEDLINE's search limit of 1966. Because of the limited number of published cases, all were reviewed. Data related to epidemiology, clinical manifestations, diagnosis and treatment were collected on each case. When possible, cross-references from case series or reviews were used to corroborate and supplement data for a given case. There were 40 cases identified as wound botulism. The case fatality rate was 10%. The 36 survivors had significant morbidity requiring prolonged medical care. Wound botulism is a rare life-threatening complication of trauma and i.v. drug abuse. The diagnosis should be considered in any patient with either of these risk factors who develop paresis of cranial nerves and a descending pattern of weakness. Treatment, including administration of antitoxin, should be initiated prior to definitive diagnosis by microbiologic laboratory tests.

Painless abruptio placentae associated with disseminated intravascular coagulation and syncope.

Abruptio placentae is a complication of pregnancy associated with significant morbidity and mortality for both fetus and mother. The presence of uterine pain and tenderness traditionally has been considered a useful criterion for distinguishing abruptio placentae from other causes of bleeding in pregnancy. We report the case of a 25-year-old woman who presented with painless abruptio placentae and coagulopathy during the second trimester. This case illustrates the importance of considering this diagnosis in pregnant patients with vaginal bleeding.

Short-wave ultraviolet irradiation increases photo-affinity labeling of benzodiazepine sites.

Photoaffinity labeling of benzodiazepine sites with [3H]-flunitrazepam was examined using either long-wave (366 nm) or short-wave (254 nm) ultraviolet irradiation. A multiple exposure protocol was employed so that the time course of the process could be determined as well as the fraction of total sites labeled. At 366 nm, approximately 20% of the total sites present were labeled and the remainder showed reduced affinity for flunitrazepam, in agreement with published reports. When membranes from either cortex or cerebellum were irradiated at 254 nm, however, the fraction of sites labeled increased above 40%. The change in the ratio of labeled sites to those showing reduced affinity, as well as differences in the time courses of the two phenomena, are taken as evidence that the labeling and affinity change are independent processes rather than two effects of a single event. Inhibition of labeling by clonazepam and Ro15-1788 indicated the "central" nature of the labeled sites.
