ORLANDO, Fla. -- In the three-month period from Sept. 1 to Dec. 1, 2009, more than 567,000 medication alerts sounded at Sisters of Mercy Health System in St. Louis. Its no wonder alert fatigue had set in among physicians. During a poster presentation at HIMSS11, Physician Informaticist Michael Hunt, DO, explained revisions made to the medication alert process to trim the frequency of the alerts, helping physicians to better tune in when the alerts sounded.
