Healthcare Ready has activated its Rx Open mapping tool to help health care providers and patients in Louisiana, Texas and Arkansas find open pharmacies in flooded areas. President Obama Sunday declared a major disaster in portions of southern Louisiana due to severe storms and flooding. The historic flooding forced Ochsner Medical Center Baton Rouge (O’Neal campus) to transfer a number of critically ill patients to other Ochsner facilities. Several post-acute facilities and nursing homes also were evacuated, according to the Louisiana Hospital Association.
