Attracting insured patients to Texas-based JPS Health Network has long been a priority of Chief Executive Officer David Cecero, but physicians and community activists say JPS' chase of the insured can squeeze out low-income patients and divert resources. Cecero says insured patients can help make up for the money-losing services that JPS provides to low-income and other uninsured residents. The strategy is based on cost-shifting common to hospitals: Profits from some patients are used to make up for losses on others.
