In case of vertical arrangements in Healthcare services, providing an option to buy medications from outside for prescription generated in hospital could be additional boon to patient, however there should be no substitution on generic or branded generic name which is mentioned on prescription. There is a clinical experience with generic or branded generic medicines with healthcare providers hence that professional sanctity should be followed.
Portability of Patient Data is really marvellous thought and should be deployed so that multiple costs are saved from patient point of view.
