Kristen Diane Parker, the surgical technician who allegedly stole needles filled with painkiller for ones filled with saline solution and potentially infected with hepatitis C, has just gone "viral." In addition to working at Rose Medical Center in Denver and a surgery center in Colorado Springs, Parker also worked recently at Northern Westchester Hospital in Mount Kisco, New York, according to 7News, triggering testing there in as many as 2,800 patients. WPIX 11 in New York reports that Parker worked in the hospital's operating rooms from October of 2007 to February of 2008 and that the patients who had surgery in those months should be tested for the liver-damaging hepatitis C, which Parker has. Meanwhile, Colorado health officials are worked with Rose to change investigative procedures to fix a breach of public trust, according to The Denver Post. Other changes include new medication dispensing machines that are accessed by fingerprint scan.
