TY - JOUR T1 - WHy accountable care organizations are not 1990s managed care redux AU - Emanuel EJ Y1 - 2012/06/06 N1 - 10.1001/jama.2012.4313 JO - JAMA SP - 2263 EP - 2264 VL - 307 IS - 21 N2 - Many people are concerned that accountable care organizations (ACOs) and other delivery system reforms in the Affordable Care Act will simply bring back the managed care days of the 1990s. These skeptics suspect that payment reforms to control high and increasing costs will simply lead to gate keeping and service denial rather than the promise of care redesign and coordination that removes unnecessary cost and delivers better outcomes.
