Financially strapped Miami-based Jackson Health System has stopped paying for dialysis treatments for 175 poor patients with failing kidneys. Jackson, Miami-Dade's County's government health system intended to be a safety net for the poor and uninsured, said it expects to save $4.2 million by stopping payments for outpatient dialysis treatment for the 175 patients. Of those, other avenues for care have been found for all but 41, said a Jackson spokesman.
