Hospitals may have to fork over more power, but not necessarily higher pay, to get physicians to participate in accountable care organizations and other cooperative initiatives. That’s the upshot of a report on how hospital and physician relationships are evolving under healthcare reform, released today by PriceWaterhouseCoopers’ Health Research Institute. A full 45 percent of physicians say they would want more money if they went to work for a hospital–an average of 2.4 percent. But a total of 55 percent said they either wouldn’t expect a pay hike (38 percent), or that they’d take a pay cut (17 percent). In an interesting quid pro quo, more than 60 percent of physicians say they’d accept performance-based compensation as part of the deal. They say they’d want half of their pay to be salary, but that hospital employers could base the rest on quality metrics like productivity, patient satisfaction and cost of care.
