Real-life cost of vitamin K antagonist treatment in patients with non-valvular atrial fibrillation in France in 2013

Incidence, prevalence, and treatment of anemia of non-dialysis-dependent chronic kidney disease: A retrospective database study in France

BACKGROUND

Minimal data are available regarding the prevalence and incidence of anemia among patients with non-dialysis-dependent chronic kidney disease (NDD-CKD) in France.

METHODS

This was a retrospective non-interventional study of patients with a record of NDD-CKD in the Echantillon Généraliste des Bénéficiaires (EGB) database between January 01, 2012, and December 31, 2017. The primary objective was to estimate the annual incidence and prevalence of anemia of NDD-CKD. Secondary objectives included description of the demographics and clinical characteristics of patients with NDD-CKD-related anemia. An exploratory objective was to use machine learning to identify patients from the general population that might have NDD-CKD but without a recorded ICD-10 diagnosis of CKD.

RESULTS

During 2012-2017, 9865 adult patients in the EGB database had confirmed NDD-CKD; of these, 49.1% (4848/9865) had anemia. From 2015 to 2017, estimates of incidence (108.7-114.7 per 1000 population) and prevalence (435.7-449.5 per 1000 population) of NDD-CKD-related anemia were stable. Less than half of patients with anemia of NDD-CKD were treated with oral iron, and approximately 15% were treated with erythropoiesis-stimulating agents. Based on adult French population projections in 2020 and an estimated prevalence rate in 2017 of 42.2 per 1000 population for confirmed plus possible NDD-CKD (as a proportion of the general French population), the estimated number of patients with possible NDD-CKD in France was 2,256,274, approximately five-fold greater than the number identified by diagnostic codes and hospitalizations.

CONCLUSIONS

Anemia of NDD-CKD was shown to be a constant long-term burden in France, and its apparent prevalence may still be significantly underestimated. Given the potential treatment gap, additional initiatives to better identify and treat NDD-CKD anemia may improve patient management and treatment outcomes.

Real-world cost-effectiveness of rivaroxaban compared with vitamin K antagonists in the context of stroke prevention in atrial fibrillation in France

Objective

The objective was to assess the real-world cost-effectiveness of rivaroxaban, versus vitamin K antagonists (VKAs), for stroke prevention in patients with atrial fibrillation (AF) from a French national health insurance perspective.

Methods

A Markov model was developed with a lifetime horizon and cycle length of 3 months. All inputs were drawn from real-world evidence (RWE) studies: data on baseline patient characteristics at model entry were obtained from a French RWE study, clinical event rates as well as persistence rates for the VKA treatment arm were estimated from a variety of RWE studies, and a meta-analysis provided comparative effectiveness for rivaroxaban compared to VKA. Model outcomes included costs (drug costs, clinical event costs, and VKA monitoring costs), quality-adjusted life-years (QALY) and life-years (LY) gained, incremental cost per QALY, and incremental cost per LY. Sensitivity analyses were performed to test the robustness of the model and to better understand the results drivers.

Results

In the base-case analysis, the incremental total cost was €714 and the total incremental QALYs and LYs were 0.12 and 0.16, respectively. The resulting incremental cost/QALY and incremental cost/LY were €6,006 and €4,586, respectively. The results were more sensitive to the inclusion of treatment-specific utility decrements and clinical event rates.

Conclusions

Although there is no official willingness-to-pay threshold in France, these results suggest that rivaroxaban is likely to be cost-effective compared to VKA in French patients with AF from a national insurance perspective.
