† only most responsible diagnosis was used
Notes: Reported diagnoses may have occurred post-admission. In 2001/2002, Canadian hospitals used one of three disease classification systems: the International Classification of Diseases, 9th revision (ICD-9); the International Classification of Diseases, 9th revision - Clinical Modification (ICD-9CM); or the International Classification of Diseases, 10th revision, Canadian Adaptation (ICD-10-CA). Standardization of disease coding with ICD-9 conversion tables and conceptual cross-walks were performed; some conceptual discrepancies in coding remain for acute myocardial infarction and may have produced slight undercounts in jurisdictions using ICD-10. In ICD-9, acute myocardial infarction was classified as such for 8 weeks from onset; in ICD-10-CA, acute myocardial infarction is classified as such if onset was within 4 weeks. Rates for cancer conditions represent incomplete counts of total cancer cases because admissions with most responsible diagnosis of chemotherapy report cancer secondarily.
