Every year there are approximately 400,000 medication errors involving hospitalized patients. Many are medications given at the wrong time or not at all. Of those 400,000 somewhere between seven and 9,000  of those errors result in the death of a patient. RaDonda Vaught, a nurse employed at the Vanderbilt University Medical Center, caused the death of a patient with a medication error. I have been thinking about Ms. Vaught a lot lately.
