As public health professionals, we recognise a gap between scientists and decision makers. Firstly, communication is a problem. Scientists and decision makers do not use the same language. Because decision makers are usually not current in complex analytical approaches, study results must be put forth in a compelling manner—for example, through visually interesting presentations that accurately and effectively summarise complex analyses.
Secondly, time is a problem. Decision makers seldom have time to read the scientific literature. Scientists must be trained to write for policy makers. Another option is creating a new specialty of science that translates science into clear public health language. From time to time, scientists who are effective translators must stop simply generating scientific evidence and instead recommend specific public health actions for decision makers.
Thirdly, taking initiative is an issue. Results of scientific studies must be actively communicated and marketed—not merely disseminated through publications—to the decision makers. Again, this could be done by scientists specially trained in these skills. Because of the large volume of essential scientific information, results must be carefully tailored for presentation to each intended decision maker group.
Fourthly, precise recommendations are lacking. Scientific publications should not simply end articles with the standard phrase, “our results indicate that further research is needed”, but instead should offer practical recommendations for decision makers. One suggestion is to end each article with a brief list of action items, similar to the standard abstract format at the beginning of an article, with recommendations for decision makers. Some journals in health promotion already use this format.
Finally, not all scientists publish their findings. Government agencies should encourage and facilitate government scientists to publish their findings in peer reviewed journals. Many government based scientists carry out excellent research but, because of a different focus and mandate, their work often ends up in reports of limited circulation. Journal publication is a more effective way to disseminate findings to other scientists and decision makers worldwide.
Bridging the gap between science and policy is not easy, but is feasible. Promoting communication among scientists and decision makers by creating a common language and a new breed of translational scientists will help make public health practice more effective.
