OBJECTIVES: The economic burden of heart failure (HF) has increased rapidly with the increasing prevalence and incidence of HF patients all around the world. In this abstract, the cost analysis of hospitalized HF patients is presented.  METHODS: A sample of hospitalizations (n=166, year 2011) with diagnoses related with chronic HF in a state hospital serving to a wide range of populations was evaluated. The prices for ICU stay and cardiovascular procedures paid by Turkish state health security system were applied. Indirect costs are not taken into account. RESULTS: Twelve percent of the stays were in intensive care unit (ICU), 35% were in medical ward only and 53% of the stays were partly in ICU and medical ward; average duration were 2.51±3.09 days, 4.45±4.07 days and 6.95±5.08 days, respectively. ICU stays are paid with fixed prices, without allowance for any extra payment for services or procedures performed while the patient stays in ICU. Average daily and total costs of ICU stay are calculated as 402€/day and 1006€, respectively. On the other hand, procedures are paid per service, while the patient stays in medical ward. Therefore the fixed amounts of payments for cardiovascular procedures, which are mostly performed during the stay of HF patients, were averaged by the frequencies of individual procedures. This yielded to 531€ per stay. Therefore the total cost of stay was obtained as 1537€, and average daily cost of stay as 221€/day.  CONCLUSIONS: These figures are quite concordant with a previous analysis reported in 2009 (total cost of stay 1617€ and daily cost of stay 245€/day) in which micro-costing methods had been applied. Therefore these figures presented in this report could be used local input parameters for health economics models for HF.
