Wake Forest Baptist Medical Center announced Wednesday that it would eliminate 950 full-time positions by June 30 following a three-year review of “its cost structure, operating model and overall strategy.” About half of those positions will be eliminated by cutting vacant, temporary and contract labor positions along with normal employee attrition and retirements, according to the medical center. But about 475 positions that are now staffed may be cut by the end of June. About one-third of the cuts will come from corporate services and administrative areas. “This change will not affect nurse-to-patient ratios, the quality of patient care or the pioneering research that is occurring at Wake Forest Baptist each day,” the medical center said in a press release.
