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 angewandte Gesundheitsforschung Berlin research database in 2013. Of these, 11.1% (19 070; 501.9 per 100 000) were diagnosed with ID/A and/or had a prescription for iron medication in 2013. The mean age of HF patients was 77.0 years (±12.0 years). Women were more frequently diagnosed with HF (54.6%). HF patients with untreated incident ID/A (1.77%) had a significantly higher all‐cause mortality than HF patients without ID/A (33.1% vs. 24.1%, P < 0.01). The analysis of health care utilization revealed significant differences in the rate of all‐cause hospitalization (72.9% vs. 50.5%, P < 0.01). The annual health care costs for HF patients with untreated incident ID/A amounted to €17 347 with incremental costs of €849 (P < 0.01) attributed to ID/A. Conclusions Heart failure is associated with a major burden for patients and the health care system in terms of health care resource utilization, costs, and mortality. Our findings suggest that there is an unmet need for treating more HF patients with ID/A with iron medication.

Background: Hyperkalemia (HK) can affect health outcomes and quality of life, as it is referred to as a potentially life-threatening condition caused by an increased serum potassium concentration in the blood. Patients suffering from heart failure or chronic kidney diseases are at a higher risk of HK, which can further be amplified by the treatment received. To date, data on HK prevalence is lacking for Germany and the aims of this study were to assess HK and compare health-relevant outcomes and healthcare costs between HK patients and non-HK patients. Methods: The InGef research database containing healthcare claims of over 4 million individuals in Germany was utilized for this retrospective, matched cohort analysis. Patients with non-acute outpatient treated and a subgroup of patients with chronic HK, were identified in 2015 with an individual 1 year pre-and post-index period, taking the first observable HK diagnosis/treatment in 2015 into account as the index event. To identify non-acute outpatient treated HK patients, at least two ICD-10-GM diagnosis codes E87.5 "Hyperkalemia" and/or prescriptions of polystyrene sulfonate were required. Chronic HK patients had additional diagnoses and/or prescriptions in all quarters following the first observable HK diagnosis. Patients without HK were matched 1:1 to the respective HK cohorts. Results: In the year 2015, 3333 patients with non-acute outpatient treated HK were identified of which 1693 were patients with chronic HK. After matching, 3191 and 1664 HK patients and controls were available for analysis. A significantly higher number of hospitalizations was observed for both HK cohorts in comparison to their matched controls. Dialysis initiation as well as the healthcare costs were higher for both HK cohorts when compared to their matched counterparts.

Purpose Secondary hyperparathyroidism (SHPT) of renal origin is a progressive complication in chronic kidney disease (CKD) and is associated with serious osseous and non-osseous complications, CKD progression, and economic burden for healthcare systems worldwide. We aimed at assessing characteristics, healthcare resource utilization, and costs of incident SHPT patients in CKD stage 3 (CKD3) and 4 (CKD4), using administrative claims data. Methods German claims data were used to identify CKD3 and CKD4 patients, who were stratified by the occurrence of incident SHPT. Patients with SHPT were matched 1:1 to non-SHPT patients with the same CKD stage using propensity scores. Matched groups were compared during a 2-year follow-up period. Results Overall, 1156 CKD3 and 517 CKD4 incident SHPT patients and their respective matches were identified. Mean number of all-cause hospitalizations were significantly higher among SHPT patients (2.7 vs. 2.0 in CKD3, 2.8 vs. 1.5 in CKD4) during follow-up. Similarly, the mean number of outpatient encounters was significantly higher among the SHPT cohorts (95.0 vs. 64.3 in CKD3, 101.4 vs. 49.8 in CKD4). SHPT patients progressed to CKD5 more often (6.1% vs. 1.2% from CKD3, 26.7% vs. 2.9% from CKD4, both P < 0.01) resulting in a higher proportion of dialysis (6.1% vs. 1.3% in CKD3, 22.1% vs. 3.7% in CKD4, both P < 0.01). Consequently, average all-cause healthcare costs significantly increased per patient (€19,477 vs. €15,115 in CKD3, €25,921 vs. €12,265 in CKD4). Conclusions Patients with CKD3&4 and incident SHPT of renal origin presented with significantly higher healthcare resource utilization and costs, as well as increased disease progression compared to non-SHPT patients.

% of the population) and expert opinion. A global Markov model was adopted to predict the number of subsequent cardiovascular events in this population treated with aspirin in secondary prevention. Healthcare costs were based on corresponding reimbursement tariffs. Indirect costs of atherothrombotic disease were calculated based on claims from Czech Social Security Administration (CSSA) database. Results: A total number of 49,215 patients suffering from both CAD and PAD was estimated. In lifetime horizon, these patients will develop 18,766 myocardial infarctions, 7,439 strokes, 6,639 cases of extracranial and 1,525 intracranial haemorrhage, 5,311 cases of acute limb ischaemia, 4,648 amputations, 3,098 cases of venous thromboembolism and 22,292 cardiovascular deaths. From a healthcare payer perspective, all these events will be associated with a total cost of V360.7 million. According to CSSA database, CAD or PAD induce 1,946 cases of invalidity per year, corresponding to V7.4 million of invalidity pensions annually and V24.7 million loss of productivity/year. Moreover, CAD or PAD lead to 4,802 sickleaves each year, corresponding to annual productivity loss of V55.5 million. In sum, these indirect costs equal to V87.6 million per year. Conclusions: The costs associated with atherothrombotic diseases are substantial. To our knowledge, this is the first Czech study evaluating the burden of atherothrombotic diseases from societal perspective. Our estimates may support future health policy decisions concerning various prevention and intervention programs.
