Playing the Oregon health insurance lottery Health coverage in the USA is not universal. A contributing factor is that one in six people do not have health insurance, and the out-of-pocket costs of receiving timely treatment can be prohibitive.1 To reform US health care, President Barack Obama enacted the Patient Protection and Affordable Care Act, colloquially known as Obamacare, in 2010.2 According to this law, children, parents, and adults without children who are not entitled to Medicare and who have family incomes of up to 133% of the federal poverty line are eligible for Medicaid, in opted-in states, as of Jan 1, 2014. Although the political struggles around Obamacare have been well publicised, evidence about the effects of increasing eligibility for Medicaid on, for example, recipients and health services has been less prominent. The Oregon Health Insurance Experiment made use of randomisation in the form of a lottery to allocate Medicaid privileges, or not, to people on a waiting list. Sarah Taubman and colleagues3 now report that people on low income who received coverage as part of a small expansion of Medicaid visited the emergency department more often than did those who did not during March 10, 2008, to Sept 30, 2009 (estimated effect of Medicaid coverage 0·41 additional visits [SE 0·12] vs 1·02 mean visits per person in the control group [SD 2·63]). Notable advantages of this study are the use of administrative data from emergency departments that are more accurate than are patientreported data, and the study design that enabled the investigators to minimise confounding factors.

An increase in emergency department use could indicate that, despite having Medicaid, individuals had difficulty accessing other health-care services or were advised to go to the emergency department. Using data from the 1999–2009 National Health Interview Survey, Cheung and colleagues4 reported that more people with Medicaid had at least one barrier to accessing primary care than did those with private insurance (16·3% vs 8·9%). Although many people will find the allocation of health provision by lottery distasteful, the Oregon experiment has provided useful information about the use of health resources and the effects on health and other outcomes.5 This evidence should prove powerful as plans are drawn up for the more inclusive US health system of the future.
