Medical errors are the third leading cause of death in the United States according to a recent study. After cancer and heart disease, medical errors kill Americans more than anything else. There are at least 251,454 deaths due to medical mistakes annually in the United States. Deaths at home or at nursing homes were not counted in the study, thus, the actual number of deaths caused by medical errors is much higher. The study was performed by researchers at Johns Hopkins University. The report was published in the British Medical Journal.
