In principle I am not opposed to turning over much of routine algorithmic primary care to NPs and PAs. Indeed, in the outpatient practices that I've seen, the nurses are the ones who pretty much do everything (immunizations, EKGs, spirometry, blood draws, rapid strep, cold agglutinin) anyway. Primary care physicians could become managers of a certain number of "mid-level providers" and could field any problems that the NPs and PAs don't feel comfortable with. This might be able to avert some of the coverage without access problems that a universal system will create in this country.
Two of the points of the article that I am less comfortable with are: 1) Expert systems software can guide generalists through the same decision-making steps that a specialist would take, and 2) TeleMedicine.
1) As much as we would like to make the complicated aspects of medicine a science, it most certainly is not. It's still an art and always will be. Even the scientific seemingly objective parts of medicine (lab tests, radiographs) are fraught with assumptions and other baggage that complicate interpretation and defy a simple flowchart. Medical knowledge only continues to expand, making specialists more and more necessary to give the best, most up-to-date care. So having my internist follow a flowchart to deal with my rheumatoid arthritis does not sound comfortable.
2) If you don't touch, hear, see, and smell the patient, you cannot provide the best possible care. Can TeleMedicine be utilized in areas that are truly rural and hard-up to get a doctor to travel out there? Sure. Is it a model for healthcare delivery generally? No.
And the article seems to insinuate that fewer doctor salaries will keep healthcare costs down. Apparently they are not informed that salaries have not kept pace with inflation even as cost have outstripped inflation. The third-party payers, the new-fangled devices, the branded drugs, and over-the-top whatever it takes to keep you alive for another few hours medicine is where the money goes in our system.
