Barriers and facilitators to the implementation of interventions for medically unexplained symptoms in primary care: A modified Delphi study.

Objective: Medically Unexplained Symptoms (MUS) are physical symptoms that last for longer than several weeks and for which no (sufficient) somatic explanation can be found. Interventions for treating MUS in primary care are available, but their implementation in daily practice appears difficult. In the current study we aim to explore key barriers and facilitators to the implementation of MUS-interventions in primary care.
