I'm not a fine print expert, so I asked my docs. None had anything positive to say about universal health care.
Fine, said some, for five minute consults for patients w/a simple cold, or standard med maintenance appts for asthma/diabetes, but major suxor for those w/a serious illness, and even worse for those who get seriously ill, and need a diagnosis.
Many said it will be similar to an HMO, and added that, near the top of a very long list of reasons they're not "in" for this is that so many diagnostic tests will require approval from a board. Same for certain meds.
From the patient's perspective, they have the option to pay for tests out of pocket while they wait for a board's decision, but if they're unable to afford it, they, and their doc, have to wait.
If a test is denied by the board, both doc and patient can wait through the appeal process. If the appeal is denied, as with the meds, the patient can either pay, or simply do without.
From the doc's perspective, a delay or denial of many of their diagnostic tools, higher patient quotas, the addition of more forms, having to deal with more agencies, will impair their ability to their job.
Participating docs' income will be regulated, and, combined with all the above, "better" docs will not want to participate. (Though there could be "fines" imposed on those who choose to not play.)
Marginal docs, red tape wound around tests and meds, quotas, less face time per patient, and the care provided will suffer, and so will the patients.
