“Past performance is no guarantee of future results,” goes the boilerplate warning on financial investments. The caution is worth keeping in mind in the wake of a recently published study that found that expanding Oregon’s Medicaid program in 2008 led to a 41 percent increase in emergency department (ED) use by many of those newly covered by the program.
The study, by an esteemed group of researchers (some of whom are affiliated with the National Bureau of Economic Research) is the latest to emerge from the Oregon Health Insurance Experiment. This series has focused on the effects of 2008-2009 policy changes that led thousands of previously uninsured Oregonians to enroll in Medicaid. The latest study found that costly visits to the ED rose across the board over a two-year period, including for relatively simple conditions, such as headaches, that could easily have been treated in primary care settings.
