The most recent HealthGrades Patient Safety in American Hospitals study has found that medical errors caused an $8.8 billion cost to Medicare and 238,337 preventable deaths between 2004 and 2006. The study also found that patients treated at the best performing hospitals had a 43% lower chance of being the victim of a medical error than patients at the poorest performing hospitals. The study examined the records of 41 million Medicare patients.
