SF Gate -- One of the sneakiest developments in healthcare is the Pay-for-Performance model, called P4P in medical/admin jargon. On the surface, you might think pay-for-performance sounds great - why should anyone pay a doctor who’s not doing a good job? And it’s not only for-profit insurers who have jumped on the P4P bandwagon, it’s even government reimbursement programs of last resort, like the Centers for Medicare & Medicaid Services (CMS), who also promote pay-for-performance programs. The P4P issue has been quietly developing momentum without most patients being aware of it. So why, now, should you care?
