Abstract
Accurate and complete registries are an important source of knowledge about cancer. The concordance of the recording of neoplasms in the Saskatchewan cancer registry with that in hospital charts and death registrations was evaluated for 368 patients. The agreement between registry and hospital charts or death registrations was excellent (kappa: 0.93; 95% confidence interval: 0.89, 0.97), with 91.3% of those with cancer having the same neoplasm recorded in their chart or death registration as in the registry. There was only one patient whose hospital chart indicated cancer who was not in the registry and one apparent major discrepancy relating to the cancer site, which was due to the recording of the primary site in the registry and a secondary in the hospital chart. Although based on a relatively small number of patients, these results suggest a high degree of consistency between cancer registry, hospital charts and death registrations in Saskatchewan.
Résumé
Des registres précis et complets sont une source importante d’information sur le cancer. La concordance de l’enregistrement des néoplasmes dans le registre du cancer dans la Saskatchewan, les dossiers des hôpitaux et les certificats de décès a été évaluée pour 368 malades. Le degré d’accord entre le registre, les dossiers des hôpitaux et les certificats de décès était excellent (kappa: 0,93; intervalle de confiance à 95 %: 0,89, 0,97), avec 91,3 % de ceux avec le cancer ayant le même néoplasme enregistré dans leurs dossiers ou leurs certificats de décès comme dans le registre. Il y avait un seul malade où le dossier d’hôpital indiquait un cancer qui n’était pas dans le registre et apparemment, un désaccord important concernant le site d’un cancer où le site primaire avait été inclus dans le registre mais le site secondaire pour le dossier de l’hôpital. Bien qu’ils soient basés sur relativement un petit nombre de malades, ces résultats suggèrent un haut degré de cohérence entre le registre du cancer, les dossiers des hôpitaux et les certificats de décès dans la Saskatchewan.
