Patients face growing cost sharing through higher deductibles and other out-of-pocket costs, with uncertain effects on clinical decision making. The study found that while almost 80 percent of physicians consider patient costs when prescribing a generic over a brand-name drug, far fewer consider patient costs when deiding what diagnostic tests to recommend (51.2%) or deciding whether to hospitalize a patient when outpatient treatment is an option (40.2%). Cost-sharing arrangements targeting patients are likely to have limited effects in safely reducing health care spending because physicians do not routinely consider patients out-of-pocket costs when making decisions regarding more expensive medical services.
