Doctors at the University Hospitals of Cleveland see an immediately recognizable symbol pop up alongside certain drugs when they sign in online these days to prescribe medications for patients: $$$$$. The dollar signs, affixed by hospital administrators, carry a not-so-subtle message: Think twice before using this drug. Pick an alternative if possible. The ... approach is just one of the strategies hospitals nationwide are using to try to counter drug costs. The increases often involved brand-name drugs with little or no competition as well as commonly used generics around for decades. Among those tagged were Nitropress and Isuprel, injectable heart medications that are a staple at many hospitals. Their 2015 list prices rose more than 200 percent and 500 percent, respectively. Hospital officials around the United States point to similar experiences, saying their predicament illustrates one dimension of a broken prescription-drug system. A recent Bloomberg Business survey of about 3,000 brand-name prescription drugs found that prices had more than doubled for 60 medications since December 2014 and at least quadrupled for 20. Prices for many other drugs continued to rise at 10 percent or more annually. "The patient doesn't initially see the price increase," said Scott Knoer, chief pharmacy officer at the Cleveland Clinic. "But it raises the cost for the hospital. Eventually, it catches up and it raises the cost for insurance companies, which is passed on to employers, employees and taxpayers."
