Canadian trends in spending on liver hospitalizations and transplants: 2004-2020.

ABSTRACT

Background: The incidence and prevalence of liver disease are increasing and contribute to significant morbidity and mortality. In Canada, more than 3 million people live with liver diseases, accounting for approximately 2% of all hospitalizations. However, it remains unclear how much liver hospitalizations cost the Canadian health care system. Thus, this study estimates the cost of liver-related hospitalization across Canada. Methods: We conducted a population-based, retrospective study using acute inpatient admission data for liver-related hospitalizations obtained from the Canadian Institute for Health Information. We calculated the total and the average nominal spending for liver hospitalizations nationally from April 1, 2004, to March 31, 2020, based on fiscal year (FY). In addition, we stratified the average liver hospitalization spending based on age and sex group. Results: Canada spent $947 million on liver-related hospitalizations in FY2019, a 145% growth in spending from FY2004. The average liver disease-related hospitalization was estimated to be $17,506 in FY2019. Within the sub-group analysis, the age group <30 showed the highest average cost per hospitalization at $21,776; however, there was no significant difference in cost between males and females. Across the different provinces in FY2019, Alberta experienced the highest average spending per hospitalization at $23,150, whereas Ontario had the lowest spending at $15,712. Conclusions: Liver-related hospitalizations are associated with high spending that is increasing nationally with variations across provinces and territories. Our results are of great use for economic evaluations of novel interventions in the future.
