Abstract
Purpose: Biological treatment has been a game changer in the management of moderate-to-severe psoriasis. In Denmark, biological treatment for psoriasis is registered in two data sources. We aimed to describe the utilization of biologics for psoriasis in Denmark using data from both data sources separately.
Methods: We used data from two different nationwide Danish data sources: The healthcare registries and the clinical quality database, Dermbio. Utilization patterns were described by three different parameters: (1) distribution of drugs used in the first treatment episodes, (2) treatment cascade on a population level, and (3) drug survival using Kaplan Meier (KM) analysis and the proportion of patients covered (PPC) method.
Results: From January 1, 2011, to December 31, 2018, we found 1878 users of biologics in the healthcare registries and 2264 in Dermbio. Adalimumab, ustekinumab, and secukinumab were the most common first-choice treatments throughout the study period. According to the healthcare registries, it was most common to have more than one treatment episode with the same drug. In Dermbio, most were registered to have only one observable treatment episode overall in the study period. Ustekinumab showed the longest drug survival in both databases. Drug survival was longer for all biologics in Dermbio than in the healthcare registries.
Conclusion: Adalimumab, ustekinumab, and secukinumab were the most common first-choice treatments in Denmark. Overall, ustekinumab showed the longest drug survival. We observed important differences in treatment cascades and drug survival between Dermbio and the healthcare registries, which should be considered when using these data sources to perform drug utilization studies on biologics.
期刊介绍：
The aim of Pharmacoepidemiology and Drug Safety is to provide an international forum for the communication and evaluation of data, methods and opinion in the discipline of pharmacoepidemiology. The Journal publishes peer-reviewed reports of original research, invited reviews and a variety of guest editorials and commentaries embracing scientific, medical, statistical, legal and economic aspects of pharmacoepidemiology and post-marketing surveillance of drug safety. Appropriate material in these categories may also be considered for publication as a Brief Report.
Particular areas of interest include:
design, analysis, results, and interpretation of studies looking at the benefit or safety of specific pharmaceuticals, biologics, or medical devices, including studies in pharmacovigilance, postmarketing surveillance, pharmacoeconomics, patient safety, molecular pharmacoepidemiology, or any other study within the broad field of pharmacoepidemiology;
comparative effectiveness research relating to pharmaceuticals, biologics, and medical devices. Comparative effectiveness research is the generation and synthesis of evidence that compares the benefits and harms of alternative methods to prevent, diagnose, treat, and monitor a clinical condition, as these methods are truly used in the real world;
methodologic contributions of relevance to pharmacoepidemiology, whether original contributions, reviews of existing methods, or tutorials for how to apply the methods of pharmacoepidemiology;
assessments of harm versus benefit in drug therapy;
patterns of drug utilization;
relationships between pharmacoepidemiology and the formulation and interpretation of regulatory guidelines;
evaluations of risk management plans and programmes relating to pharmaceuticals, biologics and medical devices.
