Since Obamacare, L.A. County ER visits show hospitals in 'state of flux'

A key measure of hospital emergency room use in Los Angeles County shows continued growth during the first six months of Obamacare, but also points to shifting patterns of where patients are choosing to receive urgent medical treatment. With the healthcare expansion last year, many are watching how the Affordable Care Act affects emergency room use. President Obama has promised his signature health law will gradually reduce expensive ER visits as access to other kinds of care is expanded. Critics contend newly insured patients — especially those enrolled in Medi-Cal, the state's low-income health program that picks up most patient costs — aren't likely to seek care elsewhere, and will overwhelm emergency rooms.
