OBJECTIVES: Chronic heart failure (CHF) affects more than 600,000 Canadians, resulting in thousands of hospitalizations and deaths each year. This study’s objective is to compare the mean cost ($CAD) of a CHF, cardiovascular, and non-cardiovascular diagnosed hospitalization amongst acute care treated CHF diagnosed patients. This study builds upon previously presented Canadian CHF hospitalization costing research. METHODS: Hospital discharge abstracts recorded between 2009 and 2013 were extracted from the Canadian Institute for Health Information’s Discharge Abstract Database and National Ambulatory Care Reporting System database. All acute care hospitalization discharge abstracts with either congestive heart failure (ICD-10 code I50.0) recorded as the most responsible diagnosis (MRDx) or contributing diagnosis amongst patients aged ≥18 were included in the study. Abstracts with a CHF MRDx were categorized in the CHF group. The remaining abstracts were categorized into either the cardiovascular group (circulatory system disease MRDx (ICD-10 I00 – I99), excluding CHF) or non-cardiovascular group (non-circulatory system disease MRDx). Discharge abstracts with missing demographics, or absent without leave or against medical advice discharge status were excluded. RESULTS:
