Michael Porter’s book "Redefining Healthcare" provides the basis of the value chain of a clinical trial. He says: don’t worry so much about the clinical practice guidelines, focus, instead, in sharing with the patient the health goals that you reasonably expect to obtain, clarify either how much of the outcome depends on the patient or how much depends on the professionals involved. Then focus on measuring the achievements in order to know at what cost you achieved them and compete in the healthcare market with these values in hand.
The clinical process’ difficulties should not cause you to lose focus: the clinical effectiveness is the only objective.
According to the methodology Care Delivery Value Channel (CDVC), the creators of a clinical trial should be able to define how to address each of the stages of a clinical trial: prevention, diagnosis, preparation, response, recovery and follow-up or monitoring. At the same time it must be ensured that the patient flows through the process smoothly, without any surprises or poor coordination, but with assurances and being kept well informed.
