A government report published Thursday shows ObamaCare is still far from achieving one of its goals.

President Barack Obama’s health care reform law, the Affordable Care Act, has brought the number of people lacking health insurance to a historic low. Yet it also aimed to reduce visits to emergency departments, where the uninsured would often go to receive care but which are often strained with high volumes of patients and deliver more costly services.

But findings from the Centers for Disease Control and Prevention suggest that not having health care coverage isn’t the only factor keeping people from defaulting to the ER for care, and that “ER use overall has not changed significantly after the first full year of ACA implementation.”
