Officials at Gallatin, TN-based Sumner Regional Medical Center say they're addressing procedures that led to a federal investigation into allegations of poor care provided to a man who died in the hospital's emergency room. Investigators with the Centers for Medicaid and Medicare said if the hospital had not taken corrective action, it could have cost the hospital its Medicare funding. One of the deficiencies cited in the investigation was in the nursing staff levels during one shift over a 14-day period.
