In an ongoing investigation into problems at Parkland Hospital, Brooks Egerston of The Dallas Morning News reports on a botched knee surgery that ultimately led to an amputation. The surgery was performed by a doctor in training. According to a patient safety report by the hospital, these outcomes aren't uncommon. "'We harm two patients a day in a significant way,' says the report by Parkland's patient safety officer, Dr. Angelique Ramirez. It covers patients from October 2008 through December 2009 who suffered 'prolongation of hospital stay, need for ICU care, permanent harm, or death.'"
