Working with outside computer forensics specialists , CHEMED commenced an investigation to determine the full extent of the issue .

Although there were attempted unauthorized connections to the server from the public internet during that time period , CHEMED was unable to determine whether those connections were successful and specific patient records were actually subject to unauthorized access . CHEMED is therefore providing impacted patients with notice of this incident in an abundance of caution . The following types of patient information were determined to be at risk for possible unauthorized access : patient name , procedure date , patient date of birth , patient ID , exam ID , physician 's name , and medical organization name ( CHEMED ) . ;
