In the emergency department (ED), a significant amount of radiation exposure is due to computed tomography (CT) scans performed for the diagnosis of appendicitis. Children are at increased risk of developing cancer from low-dose radiation and it is therefore desirable to utilize CT only when appropriate. Ultrasonography (US) eliminates radiation but has sensitivity inferior to that of CT. We describe an interdisciplinary initiative to use a staged US and CT pathway to maximize diagnostic accuracy while minimizing radiation exposure. ⋯ Half of the patients who were treated using this pathway were managed with definitive US alone with an acceptable negative appendectomy rate (7%) and a missed appendicitis rate of less than 0.5%. Visualization of a normal appendix (negative US) was sufficient to obviate the need for a CT in the authors' experience. Emergency physicians (EPs) used an equivocal US in conjunction with clinical assessment to care for one-third of study patients without a CT and with no known cases of missed appendicitis. These data suggest that by employing US first on all children needing diagnostic imaging for diagnosis of acute appendicitis, radiation exposure may be substantially decreased without a decrease in safety or efficacy.

The emergency department (ED) visit provides an opportunity to impact the health of the public throughout the entire spectrum of care, from prevention to treatment. As the federal government has a vested interest in funding research and providing programmatic opportunities that promote the health of the public, emergency medicine (EM) is prime to develop a research agenda to advance the field. EM researchers need to be aware of federal funding opportunities, which entails an understanding of the organizational structure of the federal agencies that fund medical research, and the rules and regulations governing applications for grants. ⋯ EM requires a broad skill set from a multitude of medical disciplines, and conducting research in the field will require looking for funding opportunities in a variety of traditional and not so traditional places within and without the federal government. The following is the discussion of a moderated session at the 2009 Academic Emergency Medicine consensus conference that included panel discussants from the National Institutes of Mental Health, Drug Abuse, and Alcoholism and Alcohol Abuse and the Centers for Disease Control and Prevention (CDC). Further information is also provided to discuss those agencies and centers not represented.

This article describes the results of the human immunodeficiency virus (HIV) and sexually transmitted infections (STI) prevention in the emergency department (ED) component of the 2009 Academic Emergency Medicine Consensus Conference entitled "Public Health in the ED: Surveillance, Screening, and Intervention." The objectives were to use experts to define knowledge gaps and priority research questions related to the performance of HIV and STI surveillance, screening, and intervention in the ED. A four-step nominal group technique was applied using national and international experts in HIV and STI prevention. Using electronic mail, an in-person meeting, and a Web-based survey, specific knowledge gaps and research questions were identified and prioritized. ⋯ While the knowledge gaps appear disparate from one another, they are related to the research priority questions identified. Using a consensus approach, we developed a set of priorities for future research related to HIV and STI prevention in the ED. These priorities have the potential to improve future clinical and health services research and extramural funding in this important public health sector.

Many adolescents who die by suicide have never obtained mental health services. In response to this, the National Strategy for Suicide Prevention recommends screening for elevated suicide risk in emergency departments (EDs). This cross-sectional study was designed to examine 1) the concurrent validity and utility of an adolescent suicide risk screen for use in general medical EDs and 2) the prevalence of positive screens for adolescent males and females using two different sets of screening criteria. ⋯ The suicide risk screen showed evidence of concurrent validity. It also demonstrated utility in identifying 1) adolescents at elevated risk for suicide who presented to the ED with unrelated medical concerns and 2) a subgroup of adolescents who may be at highly elevated risk for suicide due to the combination of depression, alcohol abuse, suicidality, and impulsivity.

This article provides recommendations for incorporating conceptual models of health behavior change into research conducted in emergency care settings. The authors drafted a set of preliminary recommendations, which were reviewed and discussed by a panel of experienced investigators attending the 2009 Academic Emergency Medicine consensus conference. ⋯ Three recommendations were made: 1) research conducted in emergency care settings that focuses on health behaviors should be grounded in formal conceptual models, 2) investigators should clearly operationalize their outcomes of interest, and 3) expected relations between theoretical constructs and outcomes should be made explicit prior to initiating a study. A priori hypothesis generation grounded in conceptual models of health behavior, followed by empirical validation of these hypotheses, is needed to improve preventive and public health-related interventions in emergency care settings.
