RESUMO
BACKGROUND: A prolonged hepatitis E outbreak occurred between 2009 and 2012 among a semi-nomadic pastoralist population in the Karamoja region of Uganda. As data on the public health problems of nomadic pastoralists in sub-Saharan Africa is limited, we sought to characterize the epidemiology and challenges to control of hepatitis E in such a setting. METHODS: A retrospective case-series investigation was undertaken. Surveillance line-lists of suspected hepatitis E cases maintained during the outbreak were analyzed. Standardized interviews and focus group discussions were conducted with key informants involved in outbreak control activities. RESULTS: Between August 2009 and September 2012, 987 hepatitis E cases with individual case-based data were identified. Of 22 total deaths, almost half occurred during the first 4 months of the outbreak. Infection attack rates were higher among males and young adults. The average time between onset of jaundice and presentation was approximately 1 week. Challenges to control were related to persistent consumption of untreated water, poor sanitation infrastructure, remote geography, nomadic movement and civil insecurity. CONCLUSIONS: The hepatitis E outbreak in Karamoja highlights the emergence of sanitation and hygiene-related disease among semi-nomadic pastoralist populations. Improving sanitation and safe water access and extending health education programs to remote pastoralist communities is crucial to prevent such diseases from becoming endemic.

This article reflects the proceedings of a workshop session, Postgraduate Education and Knowledge Translation, at the 2007 Academic Emergency Medicine Consensus Conference on knowledge translation (KT) in emergency medicine (EM). The objective was to develop a research strategy that incorporates KT into EM graduate medical education (GME). To bridge the gap between the best evidence and optimal patient care, Pathman et al. suggested a multistage model for moving from evidence to action. Using this theoretical knowledge-to-action framework, the KT consensus conference group focused on four key components: acceptance, application, ability, and remembering to act on the existing evidence. The possibility that basic familiarity, along with the pipeline by Pathman et al., may improve KT uptake may be an initial starting point for research on GME and KT. Current residents are limited by faculty GME role models to demonstrate bedside KT principles. The rapid uptake of KT theory will depend on developing KT champions locally and internationally for resident physicians to emulate. The consensus participants combined published evidence with expert opinion to outline recommendations for identifying the barriers to KT by asking four specific questions: 1) What are the barriers that influence a resident's ability to act on valid health care evidence? 2) How do we break down these barriers? 3) How do we incorporate this into residency training? 4) How do we monitor the longevity of this intervention? Research in the fields of GME and KT is currently limited. GME educators assume that if we teach residents, they will learn and apply what they have been taught. This is a bold assumption with very little supporting evidence. This article is not an attempt to provide a complete overview of KT and GME, but, instead, aims to create a starting point for future work and discussions in the realm of KT and GM.

Evidence-based medicine (EBM) has become a watchword for "the new" medical practice in the new century. Whether it represents a paradigm shift or simply a codification of the scientific method in medicine will be debated for years to come. Regardless of the place of EBM in medicine, this "movement" has served an important role in moving physician practice into the realm of becoming more scientific (albeit empirical) and transparent. There are still many problems to be addressed in the global application of the best evidence for medical practice. These include low-quality studies, delays in implementation of clear-cut improvements, outright fraud and deceit, and wariness on the part of physicians to change their practice. By working to understand the underpinnings of EBM (basic statistical concepts and critical thinking) we can advance the practice of medicine along the moral high road of science.
