The emergency department serves as a critical access point to the health system for many patients, especially those with limited resources. Screening for disease or risk factors for poor health outcomes can potentially improve both individual and population health. Screening initiatives should focus on evidence-based strategies and take local epidemiology and ED capacity into consideration. ⋯ They should also be financially sustainable for those involved. Screening can identify patients who can then be counseled, provided with prophylaxis or treatment, or referred to external resources. Through screening and intervention, the ED can serve as a vital contributor to individual and population health.

Causal diagrams are used in biomedical research to develop and portray conceptual models that accurately and concisely convey assumptions about putative causal relations. Specifically, causal diagrams can be used for both observational studies and clinical trials to provide a scientific basis for some aspects of multivariable model selection. This methodology also provides an explicit framework for classifying potential sources of bias and enabling the identification of confounder, collider, and mediator variables for statistical analyses. ⋯ We present numeric examples of effect estimate calculations and miscalculations based on analyses of the well-known Framingham Heart Study. Clinical researchers can use causal diagrams to improve their understanding of complex causation relations to determine accurate and valid multivariable models for statistical analyses. The Framingham Heart Study dataset and software codes for our analyses are provided in Appendix E1 (available online at http://www.annemergmed.com) to allow readers the opportunity to conduct their analyses.

Observational Study
Variability in Emergency Department Procedure Rates and Distributions in a Regional Health System: A Cross-Sectional Observational Study.
Procedural competency is essential to the practice of emergency medicine. However, there are limited data quantifying emergency department procedural volumes to inform the work of educators and credentialing bodies. In this study, we characterize procedural scope and volume in a regional health care system and compare rates between practice settings and over time. ⋯ All procedures were performed in all settings and rates of several emergent procedures were similar in both settings, underscoring the importance of broad procedural competence for all emergency physicians. Educators and credentialing organizations can use these data to inform decisions regarding curriculum design and certification requirements.

We prospectively assessed the diagnostic accuracy of YEARS and a modified age-adjusted clinical decision rule ("Adjust-Unlikely") for pulmonary embolism (PE) testing in the emergency department. ⋯ The "Adjust-Unlikely" rule would modestly reduce imaging and identify all cases of PE. YEARS would substantially reduce imaging but miss 1 in 14 cases of PE.

Emergency departments (EDs) are common access points for patients who are at high risk for unintended pregnancy. Low-barrier access to effective contraception represents a crucial and low-cost intervention to address this public health need. ⋯ With this novel approach, we found that emergency clinicians voluntarily participated in trainings on contraception, including low-threshold long-acting reversible contraception initiation; and, after completing these trainings, clinicians integrated these skills into their workflow in the ED. We report our results after screening 38 patients during our current Pilot Phase of implementing this program.
