This white paper identifies knowledge gaps and new challenges in healthcare epidemiology research, assesses the progress made toward addressing research priorities, provides the Society for Healthcare Epidemiology of America (SHEA) Research Committee's recommendations for high-priority research topics, and proposes a road map for making progress toward these goals. It updates the 2010 SHEA Rese...

background: maternal mortality ratio (mmr) is one of the main indicators of the millennium development goals and its accurate estimation is very important for the countries concerned. the objective of this study is to evaluate the applicability of capture‑recapture (crc) as an analytical method to estimate mmr in countries. methods: we used the crc method to estimate mmr in iran for 2004 and 20...
In regulation of exposures to hazardous environmental agents, epidemiologic evidence is especially important in defining human risk estimates. The process of developing appropriate regulations is complex, however, and depends on many considerations beyond those established to a high degree of scientific certainty. Thus the needs of regulatory agencies are involved in the way epidemiologic data ...

Confounding should always be addressed in studies concerned with causality. When present, it results in a biased estimate of the effect of exposure on disease. The bias can be negative—resulting in underestimation of the exposure effect—or positive, and can even reverse the apparent direction of effect. It is a concern no matter what the design of the study or what statistic is used to measure ...
