Days after Atlanta-based Grady Memorial Hospital closed its outpatient dialysis clinic, some patients are running into snags getting alternative care. Dorothy Leone-Glasser, an activist with Grady Advocates for Responsible Care, said she has heard from about half a dozen patients who were told they could not get dialysis treatment at Fresenius Medical Care because their names were not included on a list from Grady, they had not been screened by a physician, or that they didn't have payment vouchers for service. Fresenius has a contract with GMHC to provide dialysis care for three months.
