New Jersey residents may be surprised to hear the results of a recent study that discovered the most common medical malpractice claims were missed diagnoses for cancer and heart attacks. The researchers from the Royal College of Surgeons in Ireland Medical School reviewed more than 7,150 journal papers on medical malpractice claims, focusing specifically on claims against primary care doctors. They included 34 journal articles in their study, including those from France, Great Britain, Canada, Australia, and the United States. The researchers found that missed diagnoses were the most common malpractice claims, with between 26 and 63 percent of the cases involving a missed diagnosis. Death was the most common consequence of the alleged malpractice, being found in between 15 and 48 percent of the cases studied.
