Abstract
in English, French

The International Classification of Diseases, Ninth Revision (ICD-9) was released in the 1970s and adopted in Canada for physician billing claims in 1979 (CIHI n.d.b.; WHO & International Conference for the Ninth Revision of the International Classification of Diseases 1977). ICD-9 is no longer adequate for representing our modern healthcare environment and patient needs. We summarize the findings from a small survey of ICD-9 users across Canada - such as family physicians, researchers and decision makers - who describe the limitations of ICD-9 and the features that they would desire in a new or updated classification system.

La neuvième version de la Classification internationale des maladies, neuvième révision (CIM-9) a été publiée dans les années 1970 et adoptée au Canada, en 1979, pour les demandes de paiement faites par les médecins (CIHI n.d.b.; WHO & International Conference for the Ninth Revision of the International Classification of Diseases 1977). La CIM-9 ne correspond plus à l'environnement actuel des soins de santé ni aux besoins des patients. Nous résumons les résultats d'un bref sondage auprès d'utilisateurs de la CIM-9 au Canada, soit des médecins de famille, des chercheurs et des décideurs. Les répondants décrivent les limites de la CIM-9 et présentent les caractéristiques qu'ils souhaiteraient voir dans un système de classification renouvelé ou mis à jour.
