OBJECTIVES: More than 600,000 Canadians are afflicted with chronic heart failure (CHF), which is associated with high hospitalization and mortality rates. The objective of this study is to evaluate the mean cost ($CAD) and length of stay (LOS) amongst CHF patients treated in emergency departments (ED), stratified by survival and death outcomes. This abstract builds upon previously presented research to evaluate the costs of hospitalization due to CHF in a Canadian acute care setting. METHODS: Hospital discharge abstracts recorded between 2009 and 2013 from the Canadian Institute for Health Information’s Discharge Abstract Database and National Ambulatory Care Reporting System database were analyzed using a retrospective cross-sectional study design. The two databases contain Canadian ED, acute care, and same-day surgery discharge abstracts. Discharge abstracts with congestive heart failure (ICD-10 code I50.0) recorded as the most responsible reason for ED hospitalization amongst patients aged ≥18 were included in the study. Discharge abstracts with missing demographics, or absent without leave or against medical advice discharge status were excluded from the study. RESULTS:
