Evaluation of an online bioterrorism continuing medical education course.

INTRODUCTION: Much of the international community has an increased awareness of potential biologic, chemical, and nuclear threats and the need for physicians to rapidly acquire new knowledge and skills in order to protect the public's health. The present study evaluated the educational effectiveness of an online bioterrorism continuing medical education (CME) activity designed to address clinical issues involving suspected bioterrorism and reporting procedures in the United States. METHODS: This was a retrospective survey of physicians who had completed an online CME activity on bioterrorism compared with a nonparticipant group who had completed at least 1 unrelated online CME course from the same medical school Web site and were matched on similar characteristics. An online survey instrument was developed to assess clinical and systems knowledge and confidence in recognition of illnesses associated with a potential bioterrorism attack. A power calculation indicated that a sample size of 100 (50 in each group) would achieve 90% power to detect a 10% to 15% difference in test scores between the two groups. RESULTS: Compared with nonparticipant physicians, participants correctly diagnosed anthrax (p = .01) and viral exanthem (p = .01), but not smallpox, more frequently than nonparticipants. Participants knew more frequently than nonparticipants who to contact regarding a potential bioterrorism event (p = .03) Participants were more confident than nonparticipants about finding information to guide diagnoses of patients with biologic exposure (p = .01), chemical exposure (p = .02), and radiation exposure (p = .04). DISCUSSION: An online bioterrorism course shows promise as an educational intervention in preparing physicians to better diagnose emerging rare infections, including those that may be associated with a bioterrorist event, in increasing confidence in diagnosing these infections, and in reporting of such infections for practicing physicians.

Delaying shock for cardiopulmonary resuscitation: does it save lives?

PURPOSE OF REVIEW: Out-of-hospital cardiac arrest claims more than 450,000 lives annually in North America. Many communities have dedicated significant resources to provide rapid defibrillator response for patients in ventricular fibrillation. In spite of these efforts, mortality from out-of-hospital cardiac arrest has not improved significantly. Emerging evidence suggests some patients in ventricular fibrillation arrest may be harmed by immediate defibrillation. RECENT FINDINGS: Recent laboratory studies have shown benefit in performing a period of chest compressions (cardiopulmonary resuscitation) prior to defibrillation in models with more than 4 minutes of induced ventricular fibrillation. During the initial 4 minutes the heart is more amenable to electrical defibrillation. Between 4-10 minutes, chest compressions create some coronary perfusion and fill the left ventricle to prepare the heart for electric shock. These findings, in conjunction with most emergency medical service response times reported to be 5-8 minutes, have prompted human investigation into a strategy of chest compression first. A recent randomized controlled trial reported a fivefold increase in survival for patients with more than 5 minutes of VF who received 3 minutes of chest compressions prior to defibrillation compared with those who had not. SUMMARY: Current guidelines call for rapid defibrillation as the most important 'link' in the 'chain of survival'. For most ventricular fibrillation patients who have professional rescuers arrive after 5-8 minutes of ventricular fibrillation, however, immediate defibrillation is likely to be ineffective. Counterintuitively, these patients may benefit from a period of chest compressions prior to being shocked.

Online bioterrorism continuing medical education: development and preliminary testing.

OBJECTIVE: Education to achieve awareness and competency in responding to incidents of bioterrorism is important for health care professionals, especially emergency physicians and nurses, who are likely first points of medical contact. The authors describe the development of a computer-based approach to initial education, incorporating a screensaver to promote awareness and a Web-based approach to provide initial content competency in the areas of smallpox and anthrax. METHODS: Screensavers were developed and tested on emergency department rotating senior medical students and internal medicine interns. Conceptually, screensavers were designed as "billboards" for attracting attention to the educational domain. Five rotating images sequenced at five-second intervals incorporated a teaser question and an interactive toolbar. An interactive toolbar was linked to a Web site that provided content on smallpox and anthrax for hospital-based specialties (emergency physicians and nurses, infection control practitioners, pathologists, and radiologists). The content included both summary and comprehensive content as well as free continuing education credits in an online, specialty-specific, case-scenario format with remediation pop-up boxes. RESULTS: Formal testing indicated that the screensaver and Web site combination deployed on computers in the emergency department and the events of the fall of 2001 significantly increased the percentage of correct responses to five standardized bioterrorism questions. Formal evaluation with a randomized trial and long-term follow-up is ongoing. CONCLUSIONS: Screensavers and Web sites can be used to increase awareness of bioterrorism. Web-based education may provide an effective means of education for bioterrorism.

Information infrastructure for emergency medical services.

The pre-hospital emergency medical and public safety information environment is nearing a threshold of significant change. The change is driven in part by several emerging technologies such as secure, high-speed wireless communication in the local and wide area networks (wLAN, 3G), Geographic Information Systems (GIS), Global Positioning Systems (GPS), and powerful handheld computing and communication services, that are of sufficient utility to be more widely adopted. We propose a conceptual model to enable improved clinical decision making in the pre-hospital environment using these change agents.

An innovative approach to training hospital-based clinicians for bioterrorist attacks.

The recent attacks of September 11, 2001, and the subsequent dissemination event of anthrax in the United States demonstrated the necessity for hospitals to initiate bioterrorism education for clinicians. Events such as the release of sarin gas into the Tokyo subway by the Aum Shinrikyo cult provided some insight into how quickly emergency medical personnel may be overwhelmed by causalities of unconventional weapons. Educational interventions to prepare hospital-based practitioners for such disasters must fit among the demands of patient care, administrative duties, and continuing education within specialties. In addition, the priority placed on the topic, confusion about reputable resources to consult, and concerns of funding for preparedness training mandate the need for an authoritative, comprehensive, and easily accessible approach. A pilot project supported in part by the Agency for Healthcare Research and Quality was developed to facilitate streamlining of preparedness efforts through the implementation of interactive screen savers as an alternative to traditional educational modalities. This report presents the successful application of this model, which was quantified with pretests and posttests given to users of the system.

The Public Access Defibrillation (PAD) trial: study design and rationale.

The PAD Trial is a prospective, multicenter, randomized clinical study testing whether volunteer, non-medical responders can improve survival from out-of-hospital cardiac arrest (OOH-CA) by using automated external defibrillators (AEDs). These lay volunteers, who have no traditional responsibility to respond to a medical emergency as part of their primary job description, will form part of a comprehensive, integrated community approach to the treatment of OOH-CA. The study is being conducted at 24 field centers in the United States and Canada. Approximately 1000 community units (e.g. apartment or office buildings, gated communities, sports facilities, senior centers, shopping malls, etc.) were randomized to treatment by trained laypersons who will provide either cardiopulmonary resuscitation (CPR) alone or CPR plus use of an AED, while awaiting arrival of the community's emergency medical services responders. The primary endpoint is the number of OOH-CA victims who survive to hospital discharge. Secondary endpoints include neurological status, health-related quality of life (HRQL), cost, and cost-effectiveness. Data collection will last approximately 15 months and is expected to be completed in September 2003.

Prevalence and factors associated with gonorrhea and chlamydial infection in at-risk females presenting to an urban emergency department.

BACKGROUND: Patients without a regular healthcare source are less likely to be tested, diagnosed, and treated effectively for sexually transmitted diseases (STDs). Emergency departments (EDs) are a major healthcare source for patients without health insurance or primary care providers. GOAL: This study evaluated the prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae in women aged 15 to 35 years presenting to a metropolitan ED with genitourinary or pregnancy-related complaints and the frequency with which patients were effectively treated for these infections during routine ED care. STUDY DESIGN: Women completed an interviewer-administered questionnaire and submitted urine for ligase chain reaction (LCR) testing for C trachomatis and N gonorrhoeae. RESULTS: The combined prevalence of gonorrhea and chlamydia was 16.4% (n = 62), and factors associated with infection included younger age and greater numbers of sex partners over 30 days. Problem-oriented care failed to detect infection in most cases, and 58% of infected women left the ED without effective therapy. Through a close working relationship with the local health department, we documented that 92% had received effective follow-up therapy. CONCLUSION: Continued efforts to refine and develop tools for the diagnosis and management of cervical infections for at-risk women seen in EDs are warranted.

Integrated decision-making in response to weapons of mass destruction incidents: development and initial evaluation of a course for healthcare professionals.

INTRODUCTION: Standardized, validated training programs for teaching administrative decision-making to healthcare professionals responding to weapons of mass destruction (WMD) incidents have not been available. Therefore, a multidisciplinary team designed, developed, and offered a four-day, functional exercise, competency-based course at a national training center. OBJECTIVE: This report provides a description of the development and initial evaluation of the course in changing participants' perceptions of their capabilities to respond to WMD events. METHODS: Course participants were healthcare professionals, including physicians, nurses, emergency medical services administrators, hospital administrators, and public health officials. Each course included three modified tabletop and/or real-time functional exercises. A total of 441 participants attended one of the eight course offerings between March and August 2003. An intervention group only, pre-post design was used to evaluate change in perceived capabilities related to administrative decision-making for WMD incidents. Paired evaluation data were available on 339 participants (81.9%). Self-ratings for each of 21 capability statements were compared before and after the course. A 19-item total scale score for each participant was calculated from the pre-course and post-course evaluations. Paired t-tests on pre- and post-course total scores were conducted separately for each course. RESULTS: There was consistent improvement in self-rated capabilities after course completion for all 21 capability statements. Paired t-tests of pre- and post-course total scale scores indicated a significant increase in mean ratings for each course (all p < 0.001). CONCLUSION: The tabletop/real-time-exercise format was effective in increasing healthcare administrators' self-rated capabilities related to WMD disaster management and response. Integrating the competencies into training interventions designed for a specific target audience and deploying them into an interactive learning environment allowed the competency-based training objectives to be accomplished.
