Most epidemiological research findings are genuine and make an important contribution to public health. But, as we argued in the BMJ Global Health, epidemiology, like any other profession, is liable to malpractice. Findings are sometimes obtained from ill-designed, badly implemented, inappropriately analysed or selectively reported studies. In other words ‘bad’ studies. These have no place in global health because they undermine the willingness of the general public and governments to act upon genuine findings.
In contrast, at KIT Royal Tropical Institute, we always strive to ensure that our studies are ‘good’ studies. We recently developed our own internal guidelines for Good Epidemiological Practice (GEP), which are specifically tailored to global health epidemiology. We followed the AGREE II framework for guideline development to guarantee: 1) scope and purpose; 2) stakeholder involvement; 3) rigour of development; 4) clarity of presentation; 5) applicability; and 6) editorial independence. These guidelines are aligned with the recently published recommendations from the Dutch Society for Epidemiology.
