The value of uncertainty: the Zika and Microcefalia link
Scientific paradigm violations are common in the medical literature. This article aims to describe the principles that should guide scientific thinking, such as the philosophy of skepticism, the consideration of multiple hypothesis, epidemiological criteria to demonstrate association, concern about random errors and the need to quantify the strength of association. We use the hypothesis of causality between Zika and microcephaly to illustrate these principles and cognitive mechanisms that predispose to its violation. This is an example of dissociation between certainty and level of evidence, since the association between these two entities was confirmed at a time when there was no evidence of quality that supported this association.
期刊介绍:
The International Journal of Evidence-Based Healthcare is the official journal of the Joanna Briggs Institute. It is a fully refereed journal that publishes manuscripts relating to evidence-based medicine and evidence-based practice. It publishes papers containing reliable evidence to assist health professionals in their evaluation and decision-making, and to inform health professionals, students and researchers of outcomes, debates and developments in evidence-based medicine and healthcare.
The journal provides a unique home for publication of systematic reviews (quantitative, qualitative, mixed methods, economic, scoping and prevalence) and implementation projects including the synthesis, transfer and utilisation of evidence in clinical practice. Original scholarly work relating to the synthesis (translation science), transfer (distribution) and utilization (implementation science and evaluation) of evidence to inform multidisciplinary healthcare practice is considered for publication. The journal also publishes original scholarly commentary pieces relating to the generation and synthesis of evidence for practice and quality improvement, the use and evaluation of evidence in practice, and the process of conducting systematic reviews (methodology) which covers quantitative, qualitative, mixed methods, economic, scoping and prevalence methods. In addition, the journal’s content includes implementation projects including the transfer and utilisation of evidence in clinical practice as well as providing a forum for the debate of issues surrounding evidence-based healthcare.
