[Errors in medical practice]

The frequency of the error in Medicine is not well known but in any case it must be quite high. They are several types of errors: related to planning or performance, active or latent, and in relation to diagnosis, treatment or prevention. The consequences of the errors are potentially serious for both the patient and the doctor. The human factor exists in most of the errors, but this does mean the doctor is guilty. Lot of circumstances leads to the error which could not be avoidable: ambience and organization of the work, type of institution and task, and features of the patients. It is very important to lessen the numbers of errors in Medicine through registers of errors and research based on the system (not centered in the persons) in order to apply corrective measures to the system.
