Do not panic over healthcare costs. We may finally be on the cusp of learning to control them. So maintains McKinsey & Co. director Tom Latkovic in a new article. The key, he says: The entire system must shift to paying providers based on results, not tasks. To get there, says Latkovic, "the United States needs fewer component providers who specialize in a single task, such as taking diagnostic images. Instead, it will need more healers (providers who can achieve specific objectives for patients during episodes of care) and partners (providers who can help improve a patient's health and wellness over a longer period of time)."
