Langzeittrends in der rheumatologischen Versorgung: Erfolge und Defizite im Spiegel von 25 Jahren rheumatologischer Kerndokumentation

Real-world treatment persistence in patients with rheumatoid arthritis initiating DMARDs in Germany-a health insurance claims data analysis

OBJECTIVE

To investigate treatment patterns in patients with rheumatoid arthritis (RA) in Germany who had previously received conventional synthetic (cs) or biologic (b) disease-modifying antirheumatic drugs (DMARDs).

METHODS

Patients with RA who initiated treatment with a csDMARD, bDMARD, or Janus kinase (JAK) inhibitor between 2017 and 2018 and who had previously received csDMARD or bDMARD therapy were retrospectively selected from the Institute for Applied Health Research Berlin GmbH (InGef). Time on treatment and discontinuation risk were assessed using the Kaplan-Meier method. Cox regression identified variables associated with an increased discontinuation risk.

RESULTS

A total of 990 patients had received prior csDMARD therapy; 375 had received prior bDMARD therapy. Tumor necrosis factor (TNF)-α inhibitors and JAK inhibitors were the most commonly prescribed DMARD class in those previously treated with a csDMARD or bDMARD, respectively. In both cohorts, more patients received DMARD monotherapy than combination therapy. In the prior csDMARD cohort, median time on treatment was 276, 252, and 148 days with JAK inhibitors, TNF‑α inhibitors, and csDMARDs, respectively, and those treated with JAK or TNF‑α inhibitors were less likely to discontinue treatment than those on csDMARDs (log-rank test p-value < 0.01 for both comparisons); no significant differences were found within the prior bDMARD cohort.

CONCLUSION

This is among the first detailed analyses of RA treatment patterns in a real-world setting in Germany since the introduction of JAK inhibitors. TNF‑α inhibitors were the most commonly prescribed DMARD after failure of an initial csDMARD, while JAK inhibitors were the most common among patients previously treated with a bDMARD. In both groups, monotherapy with bDMARD or targeted synthetic DMARD was common. In the prior csDMARD cohort, treatment duration was significantly longer with JAK or TNF‑α inhibitors than with csDMARDs.

[Development of quality standards for patients with rheumatoid arthritis for use in Germany]

Despite a qualitatively and structurally good care of patients with rheumatoid arthritis (RA) in Germany, there are still potentially amendable deficits in the quality of care. For this reason, the German Society for Rheumatology (DGRh) has therefore decided to ask a group of experts including various stakeholders to develop quality standards (QS) for the care of patients with RA in order to improve the quality of care. The QS are used to determine and quantitatively measure the quality of care, subject to relevance and feasibility. The recently published NICE and ASAS standards and a systematic literature search were used as the basis for development. A total of 8 QS, now published for the first time, were approved with the intention to measure and further optimize the quality of care for patients with RA in Germany.

The Safety of Antirheumatic Drugs

Background

Drug therapy for rheumatic diseases has changed fundamentally in recent decades with the introduction of many new agents. As these drugs may have to be taken for many years, and many of them are of similar efficacy, the safety profiles of the individual substances play an important role in therapeutic decision-making.

Method

This review is based on pertinent literature retrieved by a selective search on the safety profiles of selected antirheumatic drugs.

Results

Non-steroidal antirheumatic drugs, glucocorticoids, conventional disease-modifying drugs such as methotrexate, biological agents, and janus kinase (JAK) inhibitors are all used to treat rheumatic diseases. Register and trial data show that antirheumatic treatments are relatively safe. Infections, in particular, are much less common than initially expected. Cortisone administration is an exception because of its severe long-term sequelae. Biological agents are associated with severe infectious events at a rate of 4–5 events per 100 patient years. Screening before treatment with biological agents has been shown to lower the rate of tuberculosis from 564 to 95 cases per 100 000 patient years. JAK inhibitors have a good safety profile, with respect to infections as well, but there is evidence of their association with cardiovascular problems, malignancies, and thrombosis.

Conclusion

A suitable, safe antirheumatic drug can be chosen for each patient in consideration of individual risk profiles. Regular monitoring enables the early detection of adverse effects. The risk profile of JAK inhibitors, in particular, will be studied in further trials.

Mobile Responsive App-A Useful Additional Tool for Data Collection in the German Pregnancy Register Rhekiss?

Background: The German pregnancy register Rhekiss is designed as a nationwide, web-based longitudinal observational cohort established in 2015. The register follows women with inflammatory rheumatic disease prospectively from child wish or early pregnancy until 2 years post-partum. Information on clinical and laboratory parameters, drug treatment, and (adverse) pregnancy outcomes are documented in pre-specified intervals. Physicians and patients report data for the same time periods via separated accounts and forms into a web-based application (app). As data entry on mobile devices might improve response rates of patients, a responsive app as a further convenient documentation option was developed.

Methods: The Rhekiss-app is available for self-reported data retrieval since August 2017 from the App stores. For the current analysis, Rhekiss register data were used from the start of the register until 30 September 2020. The analyses were performed for forms containing information on devices. Outcome parameters were compared for mobile and desktop users for the quantity and quality of filled forms.

Results: In total, 5,048 forms were received and submitted by 966 patients. About 57% of forms were sent from mobile devices with the highest numbers in patients with child wishes (63%). Users of mobile devices were slightly younger and often had less high-education level (62 vs. 79%) compared with desktop users. The proportion of forms submitted via mobile devices increased steadily from 48% in the fourth quarter of 2018 to 64% in the third quarter of 2020. The proportion of forms received before and after the Rhekiss-app implementation increased with the highest increase of 12% for forms filled at time point 12 months post-partum. Mobile users submitted significantly more forms than desktop users (2.9 vs. 2.1), data sent via desktops were more often complete (88 vs. 86%).

Conclusion: The responsive app is a valuable additional tool for data collection and is well-accepted by patients as indicated by its increasing use in Rhekiss. Apart from desktop/browser developments, the technological adoptions within observational cohorts and registries should take smartphone requirements and developments into account, especially when patient-reported data in young, mobile patients are collected, bearing in mind that data quality could be compromised and concepts for improving data quality should be implemented.

30 Jahre regionale kooperative Rheumazentren – Erfolgreiche Verbesserung der rheumatologischen Versorgung und Versorgungsforschung

Im Rahmen des Modellprogrammes zur besseren Versorgung chronisch Kranker förderte das Bundesgesundheitsministerium (BMG) seit 1992 schwerpunktmäßig den Aufbau von Rheumazentren an 21 Orten der Bundesrepublik. Ziel war neben dem Aufbau formaler Strukturen die Verbesserung der Versorgungsqualität durch Koordination und Kooperation vorhandener Einrichtungen.

[Glucocorticoid-free and low-dose glucocorticoid treatment of rheumatoid arthritis]

Systemic glucocorticoids (GC) are a commonly used component in the treatment of rheumatoid arthritis. The aim of this article is to show the evidence for low-dose GC or GC-free RA treatment regimens. Furthermore, concepts for the de-escalation of GC treatment for RA are presented. There is sufficient evidence in the initial phase that GC treatment in addition to methotrexate (MTX) improves the patient's response to the disease activity as well as the subjective perception of impairments. The dosage of GC, however, needs to be weighed critically and the guideline-based gradual reduction leading eventually to discontinuation must consistently be pursued. In the later phases of the treatment algorithm the risks of GC administration outweigh the benefits and long-term GC treatment should therefore be reserved for exceptional cases. The lowest possible dosage always needs to be determined individually. This can be achieved by using a clinically tested scheme of reducing the prednisolone intake by 1 mg every 4 weeks. The scheme should be considered for patients with a low disease activity or remission due to disease-modifying antirheumatic drug (DMARD) treatment, if they receive 5 mg of prednisolone as long-term treatment. On the whole the positive subjective effects of GC treatment must always be weighed up against the risks of such treatment for RA patients. An ongoing process of readjusting treatment following shared-decision rules must both consistently adapt GC doses and constantly check the indications. Even if a GC-free treatment does not seem realistic, a low-dose GC treatment of RA still is and should be pursued to reduce the risks associated with the treatment.

[Regional cooperative rheumatology centers : Networking of rheumatology in Germany for over 25 years]

Over the last 25 years the regional collaborative rheumatology centers have become established throughout Germany as "catalysts" for improving rheumatological care at many different levels. With campaigns and a multitude of activities they have promoted the visibility of rheumatology in Germany together with rheumatological alliance partners and, on the scientific side, together with the German Rheumatism Research Center have contributed to the improvement of rheumatological care research in Germany. The regional cooperative rheumatology centers have become an important partner in the rheumatology network in their association as a working group of the German Society for Rheumatology and they will continue to face new tasks in the future to further improve rheumatological care in Germany.

In diesem Übersichtsartikel werden aktuelle Projekte und Perspektiven der rheumatologischen Versorgungsforschung am Programmbereich Epidemiologie des DRFZ (Deutsches Rheuma-Forschungszentrum) zusammengefasst. Versorgungsforschung wird mithilfe verschiedener Datenquellen betrieben. Neben den klassischen rheumatologischen Krankheitsregistern werden zunehmend auch Krankenkassendaten und bevölkerungsbezogene Kohorten für Analysen verwendet. Von der Datenerfassung über das Monitoring bis zu Analysealgorithmen verändern digitale Anwendungen die Versorgungsforschung der nächsten Jahre. Kollaborative Analysen mit nationalen und internationalen Kooperationspartnern unter Einbindung von Biomarkern komplettieren die Forschung am Programmbereich Epidemiologie. Die Digitalisierung der Forschungsprojekte ist ein zentraler Baustein, der die Versorgungsforschung im kommenden Jahrzehnt weiter verändern wird.

[Register and cohort studies : Overview of the most important data sources at the German Rheumatism Research Center]

Over the past 28 years the German Rheumatism Research Center in Berlin has initiated various epidemiological studies in which data on patients with inflammatory rheumatic diseases are collected nationwide and multicentric. The spectrum ranges from rheumatoid arthritis and spondylarthritis to connective tissue diseases and rheumatic diseases in childhood. Based on the respective scientific question, studies of different types were established. The German National Databases for adults and children annually collect cross-sectional data to map the care of patients. In two inception cohorts, adults with early arthritis and patients with juvenile idiopathic arthritis are investigated from disease onset. The long-term observational cohorts/registries RABBIT, RABBIT-SpA and JuMBO focus on the long-term efficacy and safety of biologic drugs and other targeted treatments. Rhekiss investigates women with inflammatory rheumatic diseases when trying to become pregnant, during pregnancy and postpartum. This article highlights each of these observational studies with its characteristics as well as national and international collaborations.

Osteoporosis in patients with rheumatoid arthritis: trends in the German National Database 2007-2017

Osteoporosis is a frequent comorbidity in rheumatoid arthritis (RA). Due to the improved treatment options for RA, we expect a long-term decrease in osteoporosis as an accompanying disease. Data from the German National Database (NDB) were used to investigate whether the frequency of osteoporosis has changed in the last 10 years. From 2007 to 2017, approximately 4000 patients were documented annually with data on therapy and comorbidity. The cross-sectional data were summarised descriptively. Age, sex, disease duration, disease activity and glucocorticoids were considered as influencing factors. The Cochrane-Armitage test for trend was used to test whether the frequency of osteoporosis at the first visit changed from 2007 to 2017. Osteoporosis frequency in RA patients (mean age 63 years, 75% female) decreased from 20% in 2007 to 6% in 2017 (p < 0.001). The decrease affected women (22% to 17%) and men (14% to 8%) in all age groups and both short-term (≤ 2-year disease duration: 9% to 3%) and long-term RA patients (> 10-year disease duration: 28% to 20%). Patients with high disease activity and patients who took glucocorticoids (GC) were more often affected by osteoporosis than patients in remission or without GC. Drug prophylaxis in patients without osteoporosis increased (20% to 41% without GC, 48% to 55% with GC). Men with GC received less prophylactic treatment than women (48% vs. 57% in 2017). In this cohort, osteoporosis in patients with RA is less frequently observed compared to former years. RA-specific risk factors for osteoporosis such as disease activity and GC therapy have declined but long-term GC use is still present. Assessment of osteoporosis in RA patients should be investigated more consistently by bone density measurement. Male RA patients still need to be given greater consideration regarding osteoporosis drug prophylaxis, especially when GC therapy is needed.

Editorial

Der systemische Lupus erythematodes (SLE) ist eine Erkrankung, welche sowohl sehr schwer und organgefährdend, wie auch eher milde verlaufen kann. Die Krankheitsausprägung ist selbst für die Rheumatologie außergewöhnlich variabel. Die charakteristischen serologischen Marker und die i.d.R. deutliche subjektive Beeinträchtigung der Patienten sind aber eine Gemeinsamkeit fast aller Patienten.
