This correspondent says the article is what is muddled and that the readers of JAMA deserve better.
According to the authors, after the Affordable Care Act launched the Medicare Accountable Care Organizations (ACOs), their stated purpose has morphed from Health-System Ver. 2.0 controlling the chronic care costs of their assigned patients to Health System Ver. 3.0 collaboratively addressing “population health” for an entire geography.
Between the here of “improving chronic care” and the there of “population health,” Drs Noble and Casalino believe ACOs are going to have to confront the additional burdens of preventive care, social services, public health, housing, education, poverty and nutrition. That makes the authors wonder if the term “population health” in the context of ACOs is unclear. If so, that lack of clarity could ultimately lead naive politicians, policymakers, academics and patients to be disappointed when ACOs start reporting outcomes that are limited to chronic conditions.
