Steve Klasko, the chief executive officer of Thomas Jefferson University Hospital in Philadelphia, wants to see fewer patients walking into his emergency room. Jefferson is investing $20 million to open two urgent-care centers, including one three blocks from the existing ER, to treat patients with routine medical needs, and build a program to allow physicians to perform consultations using video apps so that other patients never have to leave home. "The best way to save the system lots of money is to keep them out of the hospital," Klasko says.
