Medical records contain all sorts of information about people, much of it not necessarily medical but often a doctor's subjective appraisal of a person. In addition to this if incorrect information is added to a person's medical record, apparently it cannot be removed. This is completely wrong.
If a person finds that incorrect information has been added to their medical record, they should be able to get this incorrect information removed. The record should be the property of the person it relates to, not the health service.
