Rome, January 7 - A health ministry task force into the hospital deaths of four women in childbirth found medical staff and procedures were not at fault, sources said Thursday. Five women died in seven days, one of them in a home birth. The task force will report to Health Minister Beatrice Lorenzin in the coming days. The national health system must correct any mistakes that may have caused the deaths of five women in childbirth over the past week, Lorenzin said Tuesday. "We must correct possible errors," she said. "The fact is that each case was different from the others and they all took place in large hospitals with excellent reputations in our country... I hope there has been no omission of aid, on the other hand we must provide answers to the families. If mistakes were made along the way, they must be corrected immediately". Her comments came after funerals of two women who died in childbirth were held Monday.
