The medication-overview operation provides a simple method for a client to request a patient's current Medication Overview based on the information standard 'Medication Process'. The response is a Bundle of type 'searchset'. At a minimum, a List resource and Patient resource is returned, along with any other resources that the server has available for the Medication Overview. The server also returns whatever resources are needed to support the Medication Overview - e.g. linked practitioners, organizations etc. If there are no medication related clinical resources, this operation SHALL return an empty List resource containing an appropriate value for the .emptyReason element.
