Effective preventive and screening interventions have not been widely adopted in emergency departments (EDs). Barriers to knowledge translation of these initiatives include lack of knowledge of current evidence, perceived lack of efficacy, and resource availability. To address this challenge, the Academic Emergency Medicine 2007 Consensus Conference, "Knowledge Translation in Emergency Medicine: Establishing a Research Agenda and Guide Map for Evidence Uptake," convened a public health focus group. The question this group addressed was "What are the unique contextual elements that need to be addressed to bring proven preventive and other public health initiatives into the ED setting?" Public health experts communicated via the Internet beforehand and at a breakout session during the conference to reach consensus on this topic, using published evidence and expert opinion. Recommendations include 1) to integrate proven public health interventions into the emergency medicine core curriculum, 2) to configure clinical information systems to facilitate public health interventions, and 3) to use ancillary ED personnel to enhance delivery of public health interventions and to obtain successful funding for these initiatives. Because additional research in this area is needed, a research agenda for this important topic was also developed. The ED provides medical care to a unique population, many with increased needs for preventive care. Because these individuals may have limited access to screening and preventive interventions, wider adoption of these initiatives may improve the health of this vulnerable population.

The biological activity of a series of structurally diverse 3-isothiazolones (1) has been assessed by evaluating the minimum inhibitory concentration required to inhibit the growth of E. Coli. The structure and electronic properties of these derivatives have been calculated using both semi-empirical and ab initio molecular orbital methods. Multi-linear regression analysis shows no correlation between the experimental activity of the 3-isothiazolones and either the calculated geometries, electronic properties, or the frontier orbital energies of these derivatives, but a reasonable relationship is found with other parameters including their calculated solvation energies, suggesting that diffusion may play an important role in their mode of action.

Objectives: There is little evidence guiding physicians in the evaluation of acute headache to rule out nontraumatic subarachnoid hemorrhage (SAH). The authors assessed emergency physicians in: 1) their pretest accuracy for predicting SAH, 2) their comfort with not ordering either head computed tomography (CT) or lumbar puncture (LP) in patients with acute headache, and 3) their comfort with not ordering head CT before performing LP in patients with acute headache. Methods: This two-and-a-half-year prospective cohort study was conducted in three tertiary care university emergency departments with 51 emergency physicians. Consecutive patients more than 15 years of age with a nontraumatic, acute headache (onset to peak headache less than one hour) and normal results on neurologic examination were enrolled. Patients known to have cerebrospinal fluid shunt, aneurysm, or brain neoplasm, and patients with recurrent headaches of the same intensity/character as their current headache were excluded.Physicians recorded their pretest probability for SAH and their comfort with performing either no tests or an LP without first obtaining head CT. Results: The authors enrolled 747 patients (mean age 42.8 years; 60.1% female; 77.0% their worst headache; 83.4% had CT and/or LP), including 50 (6.7%) with SAHs. Physicians reported being ''uncomfortable'' or ''very uncomfortable'' with performing no test in 75.4% of cases and being ''uncomfortable'' or ''very uncomfortable'' with performing LP without CT in 49.6% of cases. The area under the receiver operating characteristic (ROC) curve for SAH was 0.85 (95% CI = 0.80 to 0.91). Conclusions: Physicians were able to moderately discriminate SAH from other causes of headache before diagnostic testing.

The CWC recommendations for emergency medicine were selected using a mixed methods approach. This top 5 list was released at the CAEP Conference in June 2015 and should form the basis for future implementation efforts.
