About 50 patients affected by the planned closing of Atlanta-based Grady Memorial Hospital's outpatient dialysis clinic will receive three months of treatment at Fresenius Medical Care at no cost to them. The costs will be picked up by the Grady Memorial Hospital Corporation while other arrangements are worked out. The outpatient clinic is expected to close at the end of business on Oct. 3. The clinic is outdated, and loses between $2 million and $4 million a year, Grady officials have said.
