Antidepressant use in pregnancy: knowledge transfer and translation of research findings.

Rationale: Knowledge transfer and translation (KT) has become an important component in health care systems worldwide. Antidepressant use in pregnancy has become a controversial subject for a number of reasons, including differing interpretations of study results.

Methods: Selected key articles were indentified and retrieved from the literature. Relevant information was extracted and synthesized into themes, addressing each of the stated objectives.

Objectives: (1) To determine how knowledge regarding the safety/risk of antidepressant use in pregnancy is created; (2) to describe different research models and statistical analyses that have been used, so as to critically evaluate the results; and (3) to identify how this information is currently disseminated.

Results: All of the methods used for examining the safety of antidepressants in pregnancy have some deficiencies in study design and analysis, thus reinforcing the need for accurate interpretations when discussing results. In addition, dissemination in both the scientific and lay press has been selective and therefore potentially biased.

Conclusion: It is critical, starting with the creators of knowledge, through to the recipients that discrepancies are resolved, as lack of clarity may impede the transfer of unambiguous evidence-based information from health care providers to patients, thus impacting decision making. For example, by implementing improved (KT) strategies, a pregnant, depressed woman, will be empowered to make a rational evidence-based decision regarding whether or not she should take an antidepressant during pregnancy.
