The expansion of health insurance and one of the assumptions within the ACA is that the use of emergency room care would decline. This was assumed to be a cost reduction tool. Old habits are hard to break and rather than decrease, the ER use has increased. This is especially true in urban areas among minority patients who are accustomed to using the ER for most care.
This is one example of why controlling health care costs and hence premiums is so difficult.
Oct. 17 (UPI) — Researchers at the University of Maryland School of Medicine were shocked to find that nearly half of all medical care in the United States is delivered at hospital emergency departments. In recent years, the percentage of care given at ERs has grown significantly, with a new study revealing a nearly 44 percent increase in visits over a 14-year period.
