When given a list of nine items as possible causes of preventable medical errors, at least half of the public sees seven of these causes as very important. The top causes as viewed by the public are overwork, stress, or fatigue of health professionals (74%); physicians not having enough time with patients (70%); not enough nurses in the hospital (69%); and health professionals not working together or communicating as a team (68%). Interestingly, the lowest-ranking cause among the public, lack of computerized medical records (46%), is something that experts in this field often cite as a main cause of preventable errors.
