Say R, Robson S, Thomson R. Helping pregnant women make better decisions: A systematic review of the benefits of patient decision aids in obstetrics. BMJ Open. 2011;1:e000261.
Objectives: Patient decision aids can be used to support pregnant women engaging in shared decisions, but little is known about their effects in obstetrics. The authors aimed to evaluate the effects of patient decision aids designed for pregnant women on clinical and psychosocial outcomes.
Conclusions: Patient decision aids have the potential to improve obstetric care. However, currently the evidence base is limited by the small number of studies, the quality of the studies and because they involved heterogeneous decision aids, patient groups and outcomes.
