For what it's worth I am a "GP" (internist) and the health care reform bill includes significant increases to payments to primary care providers from Medicaid and Medicare as part of the law. That's a major financial support for those of us taking those insurances. The reason that many of us don't is because the pay scales are much worse with those insurances than those with other insurances.
The incentives for quality and IT use in healthcare were originally actually part of laws signed during the bush administration. This was expanded during the Obama administration.
For what it's worth here the first article on mortality rates post Massachusetts health care reform "Romneycare" that was the basis for the ACA "Obamacare"

I don't think the ACA is remotely close to perfect, but the problem is most of us fail to realize what a mess health care in the US is and remains under our health care system (and by that I mean purely from the insured's standpoint)
