This approach is one of the technical dimensions necessary to support patient centeredness in information infrastructure. A vertical architecture with open interfaces is very important to build a multitude of services on to of it. Mobile devices have the great virtue to be very close to the patient and his or her behavior. Access and availability is a key factor in a successful migration to patient centered services.
At the same time i have to say that a vertical architecture is not enough. Horizontal or service oriented patterns or best practices have to be designed too in order to support healthcare delivery and processes. A landscape of infrastructure services that are well known and established is important to the success and accceptabiliy of patient oriented services.
