Officials with Indiana University Health Arnett in Lafayette say a USB flash drive containing information from more than 29,000 patients has gone missing. The hospital says the unencrypted drive disappeared Nov. 20 from its emergency department. Norma Gilbert, the hospital's director of quality and clinical excellence, said the hospital system hadn't received any patient reports of fraudulent activity as of Tuesday. The drive had spreadsheets with information of emergency department patients dating to November 2014, including patient names, birth dates, diagnoses and medical record numbers. Gilbert said the spreadsheets did not contain Social Security numbers, credit card or other financial information.
