Telemedicine in the management of rheumatoid arthritis: maintaining disease control with less health-care utilization.

OBJECTIVES: We aimed to evaluate the use of an eHealth platform and a self-management outpatient clinic in patients with RA in a real-world setting. The effects on health-care utilization and disease activity were studied. METHODS: Using hospital data of patients with RA between 2014 and 2019, the use of an eHealth platform and participation in a self-management outpatient clinic were studied. An interrupted time series analysis compared the period before and after the introduction of the eHealth platform. The change in trend (relative to the pre-interruption trend) for the number of outpatient clinic visits and the DAS for 28 joints (DAS28) were determined for several scenarios. RESULTS: After implementation of the platform in April 2017, the percentage of patients using it was stable at ∼37%. On average, the users of the platform were younger, more highly educated and had better health outcomes than the total RA population. After implementation of the platform, the mean number of quarterly outpatient clinic visits per patient decreased by 0.027 per quarter (95% CI: -0.045, -0.08, P = 0.007). This was accompanied by a significant decrease in DAS28 of 0.056 per quarter (95% CI: -0.086, -0025, P = 0.001). On average, this resulted in 0.955 fewer visits per patient per year and a reduction of 0.503 in the DAS28. CONCLUSION: The implementation of remote patient monitoring has a positive effect on health-care utilization, while maintaining low disease activity. This should encourage the use of this type of telemedicine in the management of RA, especially while many routine outpatient clinic visits are cancelled owing to COVID-19.

Does Etanercept Biosimilar Prescription in a Rheumatology Center Bend the Medication Cost Curve?

OBJECTIVE: The market entry of biosimilars is expected to bring budgetary relief. Our objective was to determine how the introduction of biosimilars influences medication costs in patients with rheumatoid arthritis (RA) and which patients gain access to biologics due to the availability of biosimilars. METHODS: Using hospital data of patients with RA between 2014 and 2018, an interrupted time series was performed. The interruption in the time series was placed at June 2016 (i.e., the introduction of the etanercept biosimilar). The changes in trends for rheumatic medication costs before and after the interruption were measured. Secondary analyses focused on explaining these trends. RESULTS: In the first quarter after the interruption, there was a decrease in total costs for biologic users of -€63,020 (95% CI -€96,487 to -€29,553, P = 0.001). The postinterruption trend did not differ from the preinterruption trend (95% CI -€6695 to €6715, P = 0.998) and after 3 quarters, the medication costs were back at the interruption level. After the interruption, the average cost per biologic user decreased by -€370 (95% CI -€602 to -€138, P = 0.005), followed by a quarterly decrease (relative to the preinterruption trend; 95% CI -€86 to -€14, P = 0.010), bending the average cost curve. The percentage of patients being treated with biologics increased in postinterruption by 0.50 percentage points quarterly (95% CI 0.38-0.62, P < 0.001). Also, the average age at the start of the first biologic increased after the interruption (P = 0.057). CONCLUSION: The average cost per patient treated with biologics decreased after the introduction of biosimilars with a persistent trend. However, the budgetary relief due to market entry of biosimilars vanished quickly due to an increase in patients treated with biologics.

One-year results after transitioning from etanercept originator to biosimilar in a setting promoting shared decision-making in rheumatology.

OBJECTIVE: The aim was to study the effect of non-mandatory transitioning from etanercept originator to etanercept biosimilar on retention rates in a setting promoting shared decision-making. METHODS: In 2016, all patients treated with etanercept originator and stable disease at the Rheumatology department in Bernhoven were offered transitioning to etanercept biosimilar by an opt-in approach. A historical cohort of patients treated with etanercept originator in 2015 was identified as the control group. Etanercept discontinuation was compared between the cohorts using Cox regression. To study the nocebo effect, reasons for discontinuation were categorized into objective reasons (e.g. laboratory abnormalities, increase in swollen joint count, allergic reaction) and subjective health complaints (symptoms perceptible only to the patient, e.g. tiredness, arthralgia). An adjusted Kaplan-Meier curve for retention of the etanercept biosimilar was made, censoring subjective health complaints as the reason for discontinuation. RESULTS: Seventy of the 79 patients eligible for transitioning agreed to transition (89%). The 1-year crude retention rate of etanercept in the transition cohort was 73% (95% CI: 0.62, 0.83), compared with a retention rate of 89% (95% CI: 0.81, 0.95) in the historical cohort (P = 0.013). This resulted in a higher risk of treatment discontinuation in the transition cohort (adjusted hazard ratio = 2.73; 95% CI: 1.23, 6.05, P = 0.01). After adjusting for the nocebo effect, the cohorts had comparable retention rates (86 vs 89%, P = 0.51). CONCLUSION: Non-mandatory transition from etanercept originator to its biosimilar using an opt-in approach in a setting promoting shared decision-making resulted in a higher discontinuation of etanercept compared with the historical cohort. This could be attributed largely to the nocebo effect.

Patient Self-Management and Tracking: A European Experience.

The shift from a paternalistic model of health care to a doctor-patient relationship in which the doctor and patient make shared decisions, requires an actively involved patient who takes responsibilities. This is why self-management by the patient with a chronic disease plays more of an important role in patient care nowadays; however, the degree of self-management varies per patient. To help stimulate patients in their self-management behavior, it is necessary to use an adequate tool, and to educate patients and health professionals. In this article, we share experiences using a digital tool for this from the Netherlands.

Biosimilars in the management of chronic inflammatory diseases: The Dutch experience.

These days, the use of biosimilars for the treatment of bio-naive patients is well established. However, the transition of patients being treated with a bio-originator to its biosimilar is still a topic of discussion. The main issue is which approach to use when initiating the non-medical transition. The first real-world examples contain both mandatory and non-mandatory approaches, resulting in a variety of acceptance and discontinuation rates. At this moment a non-mandatory approach, based on shared decision making, is preferred by international guidelines and the Task Force on the Use of Biosimilars to Treat Rheumatological Diseases. However, clear definitions of mandatory and non-mandatory are lacking, as a result of which these terms may be wrongly used in some studies. This article aims to provide an overview of transition approaches used in the Netherlands, and how the approach used relates to acceptance and discontinuation rates of the biosimilar.

Exercise participation has increased in patients with Rheumatoid Arthritis: A cross-sectional comparison between two Dutch RA cohorts.

OBJECTIVE: This study evaluates exercise participation in patients with rheumatoid arthritis (RA) and the percentage of patients that meet the recommended level of physical activity (at least 150 minutes per week moderate-intensity physical activity) in two cross-sectional questionnaires in 2013 and 2016 in two Dutch RA cohorts. METHODS: In 2013, a cross-sectional study was performed among 740 patients with RA from seven outpatient clinics from the Dutch DREAM registry. Subsequently in 2016, 498 patients with RA of the outpatient clinic of the Bernhoven Hospital (member of the DREAM registry) participated in a similar study. In both years, patients filled in an identical questionnaire about exercise participation (frequency and duration). In 2016, items about self-efficacy to become more physically active were added to the questionnaire. RESULTS: In 2016, patients with RA spent significantly more minutes per week in exercise activities compared to 2013: 180 (150-450) and 120 (60-225) minutes per week, respectively (P<0.001). The percentage of patients with RA who met the recommended physical activity level increased from 25% in 2013 to 57% in 2016. Almost half (44%) of the non-exercisers reported feeling confident to become more physically active. CONCLUSION: Compared to 2013, RA patients participated in 2016 more frequently and spent more minutes per week in exercise activities. This resulted in a higher percentage of patients who met the recommended physical activity level. A personalized physical activity program, with a focus on identifying barriers and setting personal goals, might further increase the physical activity level of patients with RA.

Implementation of the EULAR cardiovascular risk management guideline in patients with rheumatoid arthritis: results of a successful collaboration between primary and secondary care.

The updated European League Against Rheumatism (EULAR) guideline recommends cardiovascular disease (CVD) risk assessment at least once every 5 years in all patients with rheumatoid arthritis (RA). This viewpoint starts with a literature overview of studies that investigated the level of CVD risk factor (CVD-RF) screening in patients with RA in general practices or in outpatient clinics. These studies indicate that CVD-RF screening in patients with RA is marginally applied in clinical practice, in primary as well as secondary care. Therefore, the second part of this viewpoint describes an example of the successful implementation of the EULAR cardiovascular disease risk management (CVRM) guideline in patients with RA in a region in the south of the Netherlands where rheumatologists and general practitioners (GPs) closely collaborate to manage the cardiovascular risk of patients with RA. The different components of this collaboration and the responsibilities of respectively primary and secondary care professionals are described. Within this collaboration, lipid profile was used as an indicator to assess whether CVD-RF screening was performed in the previous 5 years. In 72% (n=454) of the 628 patients with RA, a lipid profile was determined in the previous 5 years. As part of routine quality control, a reminder was sent to the GP in case a patient with RA was not screened. After sending the reminder letter, in 88% of all patients with RA, CVD risk assessment was performed. This collaboration can be seen as good practice to provide care in line with the EULAR guideline.

A multidimensional 'path analysis' model of factors explaining fatigue in rheumatoid arthritis.

OBJECTIVES: Fatigue is one of the most commonly reported symptoms in rheumatoid arthritis (RA). Many factors may play a causal role on fatigue in RA patients, but their contribution and interplay is barely understood. The objective was to develop a multidimensional model of factors that explain fatigue severity in RA. METHODS: A cross-sectional study (n=228) of consecutive patients with RA was performed. Fatigue, disease characteristics and psychosocial and behavioural outcomes were collected. Baseline differences between non severely fatigued patients (CIS-fatigue <35) and severely fatigued patients (CIS-fatigue ≥35) were tested. Structural equation modeling was used to test a hypothesised model for fatigue. RESULTS: The final model includes pain, physical functioning, mood, sense of control, sleep quality and fatigue, with good fit (CFI=0.976) explaining 74% of the variance in RA fatigue. Accordingly, poor sleep quality (ß=0.42, p<0.001) and less physical functioning (ß=0.65, p<0.001) are directly related to a higher level of fatigue. Less sense of control is related to more mood disturbance (ß=0.64, p<0.001), more pain (ß=0.389, p<0.001) and less physical functioning (ß=-0.24, p<0.001). More mood disturbance is related to poor sleep quality (ß=0.78, p<0.001) and higher pain level is related to less physical functioning (ß=0.75, p<0.001). CONCLUSIONS: RA fatigue is directly influenced by poor sleep quality and physical functioning, and indirectly by sense of control, mood and pain. Treatment of these factors by psychological interventions and physical exercise could help to improve fatigue in patients with RA.

Tapering and discontinuation of methotrexate in patients with RA treated with TNF inhibitors: data from the DREAM registry.

OBJECTIVES: To study the number of patients that taper or discontinue concomitant methotrexate (MTX) in daily practice in patients with rheumatoid arthritis (RA) treated with tumour necrosis factor inhibitor (TNFi) and to analyse the effects of that adaption on disease activity and drug survival. METHODS: Data were collected from the Dutch Rheumatoid Arthritis Monitoring (DREAM) registry. Patients who started their first TNFi were included in the study. Treatment effectiveness after MTX tapering or discontinuation was analysed using Disease Activity Score of 28 joints (DAS28). Drug survival of the TNFi was analysed using the Cox proportional hazard model with a time-dependent covariate. RESULTS: In 458 patients (34%), MTX was tapered, 126 patients (10%) discontinued MTX and 747 patients (56%) continued MTX at the same dose. On average, DAS28 improved after tapering MTX (-0.40, -0.45) and after stopping MTX (-0.28, -0.12) at 6 and 12 months. In the taper group, 21% of the patients relapsed (DAS28 increase >0.6), and in the discontinuation group this was 21% and 24% at 6 and 12 months, respectively. Patients who taper and discontinue MTX have a similar DAS28 score over time as patients who continue MTX. Moreover, there was no influence of tapering or discontinuation of MTX on long-term drug survival of TNFi. CONCLUSIONS: In daily practice, tapering or discontinuation of concomitant MTX in patients with RA treated with TNFi frequently occurs and it does not seem to influence the average DAS28 over time or the long-term TNFi drug survival. It appears that in daily clinical practice the correct patients are selected to taper or discontinue MTX.

Predictors for the 5-year risk of serious infections in patients with rheumatoid arthritis treated with anti-tumour necrosis factor therapy: a cohort study in the Dutch Rheumatoid Arthritis Monitoring (DREAM) registry.

OBJECTIVE: The use of TNF inhibitors leads to an increased risk of serious infections in RA. Predicting this risk would facilitate the prevention of serious infections. The objective of this study was to identify which factors are predictive of the increased risk of serious infections in RA patients treated with TNF inhibiting therapy. METHODS: Data from the Dutch Rheumatoid Arthritis Monitoring (DREAM) registry of 2044 patients with RA were used for the analyses. Data were censored at stopping TNF inhibitors or end of observation time up to 5 years. Univariate and multivariate analysis of baseline variables was performed using Cox regression with time to the first serious infection as dependent variable. RESULTS: During a follow-up time of 5 years, 128 of 2044 (6.3%) patients developed a first serious infection with a total of 141 serious infections. The incidence rate in the first year after start of TNF inhibiting therapy was 4.57 first serious infections per 100 patient-years and 2.91 per 100 patient-years over 5 years. Age, corticosteroid use, visual analogue scale (VAS) pain, HAQ, tender joint count 28 joints (TJC28) and the presence of comorbidities were significant predictors for developing a serious infection during TNF inhibiting therapy in the multivariate model. CONCLUSION: Age, corticosteroid use, VAS pain, HAQ, TJC28 and the presence of comorbidities all at baseline were significant predictors for developing a serious infection during TNF inhibiting therapy in RA patients.

Difference in the risk of serious infections in patients with rheumatoid arthritis treated with adalimumab, infliximab and etanercept: results from the Dutch Rheumatoid Arthritis Monitoring (DREAM) registry.

BACKGROUND: Tumour necrosis factor (TNF)-inhibiting therapy increases the risk of serious infections in rheumatoid arthritis (RA). However, it is not clear whether this risk differs between TNF inhibitors. OBJECTIVE: To analyse whether the risk of serious infections in patients with RA treated with an anti-TNF inhibitor is different for adalimumab, infliximab and etanercept. METHODS: Data from the Dutch RA monitoring registry were used. Incidence rates were calculated from the observed number of first serious infections and follow-up time up to 5 years. A Cox proportional hazards model with time-to-first-serious infection was used to estimate risk differences among the anti-TNF treatment groups, with correction for confounders. RESULTS: The unadjusted incidence rate of a first serious infection in patients with RA per 100 patient-years was 2.61 (95% CI 2.21 to 3.00) for adalimumab, 3.86 (95% CI 3.33 to 4.40) for infliximab and 1.66 (95% CI 1.09 to 2.23) for etanercept. Age, year of starting anti-TNF therapy, comorbidities at baseline and disease activity score 28 over time were included as confounders. No difference in risk for serious infections was found between adalimumab and infliximab with an adjusted HR (adjHR) of 0.90 (95% CI 0.55 to 1.48). The risk of serious infections was significantly lower in etanercept than in both infliximab (adjHR=0.49 (95% CI 0.29 to 0.83)) and adalimumab (adjHR=0.55 (95% CI 0.44 to 0.67)). CONCLUSIONS: The risk of serious infections in patients with RA treated with adalimumab or infliximab was similar, while the risk of serious infections in patients with RA treated with etanercept was lower than with both adalimumab and infliximab.
