Edward Miller, Dean and CEO of Johns Hopkins Medicine, has an op ed in yesterday’s Wall Street Journal where he lays out the disasterous effects that, if enacted, Obamacare will have on healthcare in the United States:

Both the House and Senate health-care reform bills call for a large increase in Medicaid—about 18 million more people will begin enrolling in Medicaid under the House bill starting in 2013, Centers for Medicare and Medicaid Services (CMS) Actuary Richard Foster estimates.

We at Johns Hopkins Medicine (JHM) endorse efforts to improve the quality and reduce the cost of health care. But we also understand all too well the impact a dramatic expansion of Medicaid will have on us and our state—and likely the country as a whole.

We’ll meet the demands placed on us because serving poor and disadvantaged populations is part of our century-old mission. But without an understanding by policy makers of what a large Medicaid expansion actually means, and without delivery-system reform and adequate risk-adjusted reimbursement the current health-care legislation will have catastrophic effects on those of us who provide society’s health-care safety-net. In time, those effects will be felt by all of us.
