Jeffrey Selwyn, an internist at New Pueblo Medicine in Tucson, Ariz., is 65, but he says he's nowhere near retiring. Unlike many docs his age who are throwing in the towel due to the increased pressures on physicians to use EHRs, Selwyn is excited. As he looks back, Selwyn admits he was something of a spokesman for older physicians who didn't want to learn the time-consuming new way of keeping patient records. Now, Selwyn is president of the board of Arizona Connected Care, one of the first accountable care organizations (ACOs) to participate in the Medicare Shared Savings Program, a federal program to lower costs and improve care.
