A randomized, controlled trial of a simple emergency department intervention to improve the rate of primary care follow-up for patients with acute asthma exacerbations.

STUDY OBJECTIVE: We determined whether a simple emergency department intervention improves the likelihood of primary care provider (PCP) follow-up after ED discharge for an acute asthma exacerbation. METHODS: This randomized, controlled clinical trial was conducted in an urban university-based ED. Participants were patients with asthma between the ages of 16 and 45 years who were treated and discharged from the ED. The study intervention was usual care or an intervention that consisted of a free 5-day course of prednisone, vouchers for transportation to and from their PCP, and a 48-hour telephone reminder to make an appointment with their PCP. The main outcome was whether the patient received follow-up care as determined by PCP contact at 4 weeks. RESULTS: One hundred ninety-two patients with asthma were enrolled over 8 months; 178 (93%) had complete follow-up. The intervention and control groups were similar with regard to age, sex, ethnicity, or years of education. The 2 groups were also comparable with respect to multiple measures of baseline access/barriers to care and severity of ED exacerbation. Patients receiving the intervention were significantly more likely to follow up with their PCP than control patients (relative risk 1.6; 95% confidence interval [CI] 1.1, 2.4). When adjusted for other factors influencing PCP follow-up care (ethnicity, prior PCP relationship, insurance status, regular car access), intervention patients were more likely to follow up with their PCP (odds ratio 3.1; 95% CI 1.5, 6.3). CONCLUSION: Providing medication, transportation vouchers, and a telephone reminder to make an appointment increased the likelihood that discharged patients with asthma obtained PCP follow-up.

The effect of written informed consent on detection of violence in the home.

UNLABELLED: Studies of programmatic interventions for victims of violence in the home may require the use of informed consent. The use of informed consent may result in ascertainment bias, with victims of violence being less likely to participate. OBJECTIVE: To investigate the effect of written informed consent on the detection of violence in the home during emergency department (ED) screening. METHODS: The authors performed a nonrandomized, controlled trial of 3,466 patients at an urban university ED. On odd days, patients (n = 1,857) were read a brief scripted statement and screened using standardized questions. On even days, patients (n = 1,609) received standard written informed consent prior to the same screening questions (writ-IC). The main outcome was the number of cases of violence in the home detected using each screening protocol. RESULTS: Fewer writ-IC patients participated in screening (82% vs 92%; p < 0.001). Despite a higher refusal rate in the writ-IC group, there was no difference in the number of victims detected by each screening method: choked/kicked/bit/punched? (writ-IC, 7.3 vs routine screen, 6.5%; p = 0.3); slapped/grabbed/shoved? (7.3 vs 6.7%; p = 0.4); threatened/actually used knife/gun to scare/hurt you? (8.3 vs 9.4%; p = 0.3); thrown object to harm you? (5.2 vs 4.6%; p = 0.4); forced sex? (5.8 vs 4.7%; p = 0.15); or afraid current/former intimate partner would hurt you physically? (13.9 vs 11.9%; p = 0.9). CONCLUSIONS: A written informed consent process in screening for violence in the home is associated with a higher refusal rate than routine screening, but use of written informed consent does not result in a lower rate of detection for multiple forms of violence. The authors did not find any support for the hypothesis that the use of written informed consent would decrease detection of violence in the home.

Pediatric emergency medicine education in emergency medicine training programs. SAEM Pediatric Education Training Task Force. Society for Academic Emergency Medicine.

BACKGROUND: The educational goal of emergency medicine (EM) programs has been to prepare its graduates to provide care for a diverse range of patients and presentations, including pediatric patients. OBJECTIVE: To evaluate the methods used to teach pediatric emergency medicine (PEM) to EM residents. METHODS: A written questionnaire was distributed to 118 EM programs. Demographic data were requested concerning the type of residency program, number of residents, required pediatric rotations, elective pediatric rotations, type of hospital and settings in which pediatric patients are seen, and procedures performed. Information was also requested on the educational methods used, proctoring EM received, and any formal curriculum used. RESULTS: Ninety-four percent (111/118) of the programs responded, with 80% of surveys completed by the residency director. Proctoring was primarily performed by PEM attendings and general EM attendings. Formal means of PEM education most often included the EM core curriculum (94%), journal club (95%), EM grand rounds (94%), and EM morbidity and mortality (M&M) conference (91%). Rotations and electives most often included the pediatric intensive care unit (PICU) and the emergency department (ED) (general and pediatric). CONCLUSIONS: Emergency medicine residents are exposed to PEM primarily by rotating through a general ED, the PED, and the PICU, being proctored by PEM and EM attendings and attending EM lectures and EM M&M conferences. Areas that may merit further attention for pediatric emergency training include experience in areas of neonatal resuscitation, pediatric M&M, and specific pediatric electives. This survey highlights the need to describe current educational strategies as a first step to assess perceived effectiveness.

An approach to community consultation prior to initiating an emergency research study incorporating a waiver of informed consent.

OBJECTIVES: In November 1996, the Food and Drug Administration (FDA) and the Department of Health and Human Services (DHHS) enacted rules allowing a narrow exception to the requirement for prospective informed consent when enrolling critically ill patients in clinical research studies of emergency treatments. These rules require that, prior to initiation of the study, the applicable institutional review board (IRB) assess the acceptability of the proposed research study to members of the community in which the research will be conducted. Specifically, the IRB must perform community consultation-a process during which community members learn about the proposed research and communicate their opinions regarding its acceptability to investigators or IRB representatives. The FDA and DHHS rules do not define specific acceptable methods for performing this community consultation. The objective of this study is to demonstrate the feasibility and utility of one proposed method for performing such community consultation. METHODS: Parents of children being seen for minor traumatic injuries in three pediatric EDs were asked to participate in a study regarding informed consent. After consent, an instructor described to the parent a prospective, randomized, placebo-controlled trial of phenytoin for the prophylaxis of posttraumatic seizures in children with severe closed head trauma. All parents were then asked whether they would have consented for their own child's participation, if their child had suffered such head injury. The parents were further asked to explain the reason(s) for their responses. RESULTS: Parents of 227 children (children's mean +/- SD age 8.0 +/- 4.8 years, 57% male) were interviewed. Sixty-six percent of parents (149/227) stated they would give consent for their child's participation. Of the 149 consenting parents, 85% (126/149) cited potential benefit to their child, 72% (107/149) cited potential benefit to other children, and 60% (90/149) cited furthering medical knowledge. Of the 78 nonconsenting parents (34% of total), 54% (42/78) cited fear of adverse effects, 39% (30/78) did not want their child to be a research subject in general, 27% (21/78) believed they needed to discuss participation with family members who were unavailable, and 26% (20/78) stated they were unable to decide unless they were in the actual situation. Parental ethnicity and household income were found to influence the consent decision, while the parent's gender, religion, language, and educational level were not associated with the consent decision. CONCLUSIONS: Community consultation regarding the acceptability of an emergency research protocol can be obtained via interview techniques in the ED. This methodology may allow investigators to obtain data on opinion from a targeted community for IRB consideration during the review of emergency research studies proposing a waiver of informed consent.

Primary varicella in adults: pneumonia, pregnancy, and hospital admission.

STUDY OBJECTIVE: To define the rate of complications of adult varicella, including pneumonia, and to determine the association of such complications with pregnancy. METHODS: Retrospective, descriptive case series of consecutive adult emergency department patients with primary varicella seen over a 31-month period in an urban county hospital. RESULTS: A total of 130 patients were identified, with a mean age of 23.9 +/- 6.1 years; 69 (53%) were female. Thirteen patients (10.0%) had pneumonia; 6 of these were hospitalized. Two patients admitted with pneumonia had significant underlying comorbid disease and expired from respiratory failure. The remaining 4 admitted patients recovered uneventfully. Four of the 7 patients discharged with pneumonia were known to have recovered uneventfully. Twenty-eight (41%) of the 69 female study patients were pregnant; 7 of these (25%) were admitted, with admission diagnoses of pneumonia (1), active labor (2), and pregnancy with varicella (4). Incidence of pneumonia in pregnant patients was 3.6% (1 of 28; 95% confidence interval, 1% to 18.3%). All 7 admitted pregnant patients and the 19 (of 21) discharged pregnant patients who were contacted recovered uneventfully. No congenital anomalies or perinatal complications were noted in the infants of the 26 mothers with documented follow-up. CONCLUSION: Hospital admission should be considered for adults with varicella pneumonia, especially if they have significant comorbid disease. It does not appear that pregnant women are at increased risk of developing varicella pneumonia.

Emergency medical service system development: results of the statewide emergency medical service Technical Assessment Program.

STUDY OBJECTIVE: The National Highway Traffic Safety Administration developed the EMS (emergency medical services) Technical Assessment Program to assist states in developing and improving their EMS systems. The main goals of this evaluation were to document the level of improvement in EMS system development following completion of the Technical Assessment Program and to identify necessary program improvements at the National Highway Traffic Safety Administration. DESIGN: Independent investigators retrospectively reviewed the information in Technical Assessment Program reports from 35 states that participated in the program during a 5-year period. RESULTS: Training and certification programs for prehospital personnel were the most well-developed elements of EMS systems. Conversely, comprehensive quality management and EMS system evaluation programs were almost uniformly absent (89% of states). Areas of need targeted for improvement included enabling legislation for EMS (60%) or trauma system development (69%), an improved mechanism to assess system resources (71%), an established or updated state EMS plan (80%), aging and unreliable communications equipment (89%), fully operational prehospital data collection systems (89%), and consistent medical oversight for all prehospital providers (92%). CONCLUSION: Program evaluation revealed that significant recommendation-based changes occurred in all components of EMS systems. The Technical Assessment Program is one tool that states can use to promote EMS system improvements.

Fecal impaction: a rare cause of respiratory arrest in childhood.

Cardiopulmonary arrest in childhood is usually due to respiratory failure leading to hypoxemia, acidosis, cardiac dysfunction, and terminal asystole. Respiratory failure is the end result of either impaired oxygenation, impaired ventilation, or both. We report a case of severe fecal impaction in an eight year old that resulted in a significant depression of ventilation by severely restricting respiratory mechanics and that ultimately progressed to respiratory failure and circulatory compromise. Physicians should be aware of this rare but possible etiology for life-threatening events in children.
