Urged by care failures at Parkland Memorial Hospital, Republican Texas Gov. Rick Perry signed a patient safety measure into law, The Dallas Morning News reported. The law, authored by Republican state Sen. Jane Nelson, requires resident doctors and hospital trainees to wear ID badges that clearly display their names and experience level. It intends to empower patients who may want to call attending physicians and other experienced providers when problems arise. Also sponsored by Nelson, another bill adds specifics to a loophole in hospital rules that require vetting of potential hires without defining the process. Article
