Use and overuse of triptans in Austria – a survey based on nationwide healthcare claims data

Abstract Background To evaluate triptan use and overuse as well as prescription patterns in Austria based on a nationwide healthcare database because data on triptan use and overuse in Austria is missing. Methods We included all persons insured with one of 19 Austrian social security institutions in 2007. Inclusion criteria comprised an age of 18–99 years, known sex, and receipt of insurance benefits. We defined triptan use as ≥1 package of a triptan dispensed in 2007 and triptan overuse as ≥30 defined daily doses dispensed in at least one quarter. Results Out of 8.295 million inhabitants in Austria, 7,426,412 persons (89.5%) were insured with a social insurance carrier and 5,918,487 persons of those insured (79.7%) fulfilled the inclusion criteria. Among the latter 33,062 persons (0,56%) were triptan users and 1970 (0.033%) were triptan overusers. The estimated proportion of persons with migraine using a triptan was less than 6%. Among users 5.9% were overusers of whom 55% overused triptans in ≥2 quarters of 2007. The median number of days of sick-leave was higher in triptan users than in non-users: due to any reason of sick-leave 12 vs. 10, p < 0.001, due to migraine 3 vs. 2, p < 0.001. The proportion of hospital admissions did not differ between triptan users and non-users. Conclusion The rate of triptan use is low in Austria but triptan users are at risk for triptan overuse. In triptan users more days of sick-leave and the same proportion of hospital admissions as in the older non-users suggest poorer health

Monoclonal Antibodies against Calcitonin Gene-Related Peptide for Migraine Prophylaxis: A Systematic Review of Real-World Data

Objective: To perform a systematic review of real-world outcomes for anti-CGRP-mAbs. Methods: Following the PRISMA guidelines, we searched PubMed for real-world data of erenumab, galcanezumab, fremanezumab, or eptinezumab in patients with migraines. Results: We identified 134 publications (89 retrospective), comprising 10 pharmaco-epidemiologic and 83 clinic-based studies, 38 case reports, and 3 other articles. None of the clinic-based studies provided follow-up data over more than one year in more than 200 patients. Findings suggest that there are reductions in health insurance claims and days with sick-leave as well as better treatment adherence with anti-CGRP-mAbs. Effectiveness, reported in 77 clinic-based studies, was comparable to randomized controlled trials. A treatment pause was associated with an increase in migraine frequency, and switching to another antibody resulted in a better response in some of the patients. Adverse events and safety issues were addressed in 86 papers, including 24 single case reports. Conclusion: Real-world data on anti-CGRP-mAbs are limited by retrospective data collection, small patient numbers, and short follow-up periods. The majority of papers seem to support good effectiveness and tolerability of anti-CGRP-mAbs in the real-world setting. There is an unmet need for large prospective real-world studies providing long-term follow-ups of patients treated with anti-CGRP-mAbs

The Journal of Headache and Pain / Prevalence, management and burden of episodic and chronic headaches : a cross-sectional multicentre study in eight Austrian headache centres

Background Episodic and chronic headaches (EH, CH) are highly prevalent disorders. Severely affected patients are usually referred to headache centres. In Austria, at least one headache centre is available in seven of nine states, but detailed multicentre data are missing. Therefore we studied prevalence rates, use of medication and health care services, impact of headaches, and comorbid depression and anxiety. Methods We included consecutive patients from eight Austrian outpatient headache centres. The patients filled-in the Eurolight questionnaire. In addition, the treating neurologist completed a questionnaire on clinical diagnoses and ever-before prophylactic medications. Results Of 598 patients screened, 441 questionnaires were analysed (79 % female, mean age 41.1 years). According to the Eurolight algorithm, 56.4 % of the patients had EH, 38.3 % had CH and 5.2 % did not give their headache frequency. The prevalence rates of migraine, tension-type headache, and probable medication overuse headache (pMOH) were 48.5 %, 6.3 % and 15.9 %, respectively. The concordance between clinical and Eurolight diagnoses was good for EH and moderate for CH. During the preceding month, acute medication was used by 90.9 % of the patients and prophylactic medication by 34 %. Ever-before use of five standard prophylactic drugs was recorded in 52.3 %. The proportion of patients with current pharmacoprophylaxis did not differ in EH and CH, whereas ever-before use was more common in CH (62.5 % was 45,3 %, p = 0.02). Patients with CH significantly more often consulted general practitioners and emergency departments, had a lower quality of life and more often signs of depression and anxiety. Conclusion This study provides comprehensive data from eight Austrian headache centres for the first time. We found a substantial number of patients with CH including pMOH and its association with more common utilization of health care facilities and greater burden. The low use of prophylactic medication requires further examination.(VLID)484316

[Consensus statement of the migraine and headache societies (DMKG, ÖKSG, and SKG) on the duration of pharmacological migraine prophylaxis].

Migraine is the most common neurological disorder and can be associated with a high degree of disability. In addition to non-pharmacological approaches to reduce migraine frequency, pharmacological migraine preventatives are available. Evidence-based guidelines from the German Migraine and Headache Society (DMKG), and German Society for Neurology (DGN), Austrian Headache Society (ÖKSG), and Swiss Headache Society (SKG) are available for indication and application. For therapy-relevant questions such as the duration of a pharmacological migraine prevention, no conclusions can be drawn from currently available study data. The aim of this review is to present a therapy consensus statement that integrates the current data situation and, where data are lacking, expert opinions. The resulting current recommendations on the duration of therapy for pharmacological migraine prophylaxis are shown here
