AIMS: The aim of this study was to assess the burden of heart failure (HF) patients with/without iron deficiency/iron deficiency anaemia (ID/A) from the health insurance perspective. METHODS AND RESULTS: We conducted a retrospective claims database analysis using the Institut für angewandte Gesundheitsforschung Berlin research database. The study period spanned from 1 January 2012 to 31 December 2014. HF patients were identified by International Statistical Classification of Diseases and Related Health Problems, 10th revision, German Modification codes (I50.-, I50.0-, I50.00, I50.01, I50.1-, I50.11, I50.12, I50.13, I50.14, I50.19, and I50.9). HF patients were stratified into HF patients without ID/A and HF patients with ID/A (D50.-, D50.0, D50.8, D50.9, and E61.1). HF patients with ID/A were stratified into three subgroups: no iron treatment, oral iron treatment, and intravenous iron treatment. A matching approach was applied to compare outcomes for HF patients without ID/A vs. HF patient with untreated incident ID/A without iron treatment and for HF patients receiving no iron treatment vs. oral iron treatment vs. intravenous iron treatment. Matching parameters included exact age, sex, and New York Heart Association functional class. An optimization algorithm was used to balance total health care costs in the baseline period for the potential matched pairs without sample size reduction. In total, 172 394 (4537.4 per 100 000) HF patients were identified in the Institut für ang...
