To determine the leading causes of hospitalization, a single primary reason for hospitalization must be determined for each hospital visit despite the fact that individuals may have multiple inter-related diagnoses. This involves choosing the most responsible diagnosis or the diagnosis associated with the longest duration of treatment during a given hospital stay. Diagnoses are classified using the Canadian modification of the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10-CA). They are grouped at the ‘chapter’ level in this report.
