Dr. Rick Donahue correctly notes that, "The secret to better patient care is time".
Note that this is one of the key values that a good concierge or "direct pay" physician offers the patient -- the ability to spend adequate time discussion problems and concerns. The current system dominated by 3rd-party insurance, Medicare and other forms of government-driven "coverage" put doctors in a position where they typically can spend only 15 minutes per patient.

Other economists warn, "ACOs May Not End Wasteful Health Spending". But I'm sure the statists will be "shocked, shocked" when ACOs "unexpectedly" cost more than projected.
