If you read Christensen's latest book "Innovator's Prescription" he analyzes the medical industry through the lens of disruptive technology, and concludes that the forces of disruptive technology have been dismantled which keep prices high. The is such a unique perspective in this health care debate because it's basically been framed as "You pay the high price", or the "Government pays the high price". However, Christensen is giving us a third option saying fix the economic engine and disruptive technology will drive prices down over time and things will get better too. Neither side of the debate can guarantee this either.
His idea is that Doctor's cost a lot of money, but when you have to have the very best analyze what's wrong with you have to pay it. Doctor's jobs are very hard and time consuming. However, certain types of care can be provided without a doctor for things that are well defined. Prevention is just such a thing. Screenings are just such a thing.
The problem right now is that technologies that enable us to screen better are often wrapped up so that you can only go to a doctor to get them. Things like MRI's and CAT scans require prescriptions from doctors. The price of a CAT scan has remained the same since it was invented. 1970 technology the same price!? Where else in our free markets does this happen?
Prevention is more easy to provide without having to tackle the prescription system, but screenings are very important part of medicine in the 21st century.
