N2 - Background: With the introduction of biologics the treatment landscape for patients with rheumatoid arthritis (RA) has rapidly expanded; however, according to German and European treatment guidelines the use of biologic disease-modifying antirheumatic drugs (bDMARD) is only indicated after insufficient response under methotrexate (MTX) doses of at least 20 mg/week (first-line treatment). The aim of the study was to analyze the guideline compliance of MTX prescription in the outpatient sector prior to treatment with biologics. Material and methods: Claims data from the AOK Lower Saxony from 2013 to 2016 were provided for all insured patients with a diagnosis of RA and bDMARD prescription during the study period. Within a patient-specific observational period of 180 days prior to the first bDMARD prescription, the maximum prescribed MTX dosage was examined. Results: Data from 90 incident and 315 prevalent RA patients were analyzed. A maximum MTX prescription of < 20 mg/week was observed in 60.0% of incident patients and in 67.0% of prevalent patients. Men had a higher mean MTX maximum dose (17.1 ± 4.8 mg) than women (14.9 ± 5.0 mg; p < 0.0001). Of the study population 29.6% received oral only prescriptions during the observational period. In 12.4% of patients a switch to parenteral administration was made. Discussion: Targeted use of the full spectrum of therapies provided prior to initiation of bDMARD treatment may contribute to cost-effective RA care. This study showed indications for potential deficits in outpatient MTX prescription practice and can raise awareness for efficient treatment.
