Decision aids for prenatal testing: A systematic review and meta-analysis.

There is a growing consensus that health care should be patient-centred, and the values and preferences of pregnant women who undergo prenatal testing need to be incorporated into the clinical decision-making process. This review reports that the use of DAs can increase pregnant women's chances of participating in prenatal testing decisions and may improve the quality of their decision-making. It also provides information on the role and practice of nurses in promoting evidence-based prenatal testing for DAs.
