The Burden of Systemic Lupus Erythematosus in Germany: Incidence, Prevalence, and Healthcare Resource Utilization.


ABSTRACT:

Introduction

We evaluated incidence, prevalence, costs, and healthcare utilization associated with systemic lupus erythematosus (SLE) in patients in Germany.

Methods

Adult patients with SLE were identified from the German Betriebskrankenkassen (BKK) health insurance fund database between 2009 and 2014. SLE incidence and prevalence were calculated for each year and extrapolated (age and sex adjusted) to the German population. The 2009 SLE population was followed through 2014. Healthcare utilization and costs for patients with SLE were calculated and compared with controls matched by age, sex, and baseline Charlson Comorbidity Index scores.

Results

This analysis included 1160 patients with SLE. Estimated SLE incidence between 2009 and 2014 ranged from 4.59 to 6.89 per 100,000 persons and prevalence ranged from 37.32 to 47.36 per 100,000. SLE incidence in Germany in 2014 was 8.82 per 100,000 persons; prevalence was 55.80 (corrected for right-censored data). At baseline, 12.8, 41.7, and 45.5% of patients were categorized as having mild, moderate, and severe SLE, respectively. Patients with SLE had greater mean (standard deviation [SD]) annual medical costs compared with matched controls 1 year after index diagnosis (€6895 [14,424] vs. €3692 [3994]; P < 0.0001) and in subsequent years. Patients with moderate or severe SLE had significantly more hospitalizations, outpatient visits, and prescription medication use compared with matched controls. Mean annual costs for 5 years ranged from €1890 to 3010, €4867 to 5876, and €8396 to 10,001 for patients with mild, moderate, and severe SLE, respectively.

Conclusions

SLE incidence in Germany increased 1.4-fold over 5 years. Patients with SLE have higher healthcare costs, and costs increase with baseline severity. Early and effective treatments may delay progression and reduce the burden of SLE.
