Various medical error taxonomies have been proposed in the literature. It is possible that because different medical error taxonomies utilise different categories, such taxonomies classify different information. This thesis reviewed published medical error taxonomies using a human factors perspective. It was found that two-thirds of the taxonomies classified systemic factors and only a third utilised theoretical error concepts. Additionally, medical error taxonomies utilising different terminologies may not share information effectively, most probably because some information may be loss during the integration process. This thesis then examined the difference between generic and domain-specific medical error taxonomies.
