OBJECTIVES: Costs of a large series of HF patients of a hospital utilization and cost study(Value in Health 2013;16:A70), were analyzed, stratified by age, sex, multimorbidity (MM), and for inflation and monetary units conversions (2015). Inflation and monetary units distort cost and transferability in Argentina. METHODS: In a multicentric 3 hospital Health Care Cost and Utilization Study, a cross sectional (1 year output), selected HF patients with Clinical Classification Software adaptation for Argentina (CCS #108) in 2008, in first (1Dx) or secondary (2Dx) diagnosis. HF prevalence, stratified by age, sex, multimorbidity (MM), measured with the Chronic Condition Indicator (CCI), mortality, HF in 2Dx, and <30 day readmissions (<30 d ReH) .Total costs (TC$), per discharge costs (mean, median), were analyzed. Current monetary values used ACECRA/CEDIM, SHIDP, 2015 medical costs study (up to 2015). International Dollar (I$) conversion PPP, used QUANDL I$ PPP (conversion rate to I$ PPP is 6,604, year 2015). Mean 95% CI were estimated with boothrapping. RESULTS:
