Medical Care Costs Associated With Rheumatoid Arthritis in the US: A Systematic Literature Review and Meta-Analysis.

ABSTRACT: OBJECTIVE:Rheumatoid arthritis (RA) is a morbid, mortal, and costly condition without a cure. Treatments for RA have expanded over the last 2 decades, and direct medical costs may differ by types of treatments. There has not been a systematic literature review since the introduction of new RA treatments, including biologic disease-modifying antirheumatic drugs (bDMARDs). METHODS:We conducted a systematic literature review with meta-analysis of direct medical costs associated with RA patients cared for in the US since the marketing of the first bDMARD. Standard search strategies and sources were used, and data were extracted independently by 2 reviewers. The methods and quality of included studies were assessed. Total direct medical costs as well as RA-specific costs were calculated using random-effects meta-analysis. Subgroups of interest included Medicare patients and those using bDMARDs. RESULTS:We found 541 potentially relevant studies, and 12 articles met the selection criteria. The quality of studies varied: one-third were poor, one-third were fair, and one-third were good. Total direct medical costs were estimated at $12,509 (95% confidence interval [95% CI] 7,451-21,001) for all RA patients using any treatment regimen and $36,053 (95% CI 32,138-40,445) for bDMARD users. RA-specific costs were $3,723 (95% CI 2,408-5,762) for all RA patients using any treatment regimen and $20,262 (95% CI 17,480-23,487) for bDMARD users. CONCLUSION:The total and disease-specific direct medical costs for patients with RA is substantial. Among bDMARD users, the cost of RA care is more than half of all direct medical costs.

Project description:IntroductionAlthough bDMARDs are effective in the treatment of RA, they are associated with dose-dependent side effects, patient burden, and high costs. Recently, many studies have investigated the possibility of discontinuing or tapering bDMARDs when patients have reached their treatment goal. The aim of this review is to provide a narrative overview of the existing evidence on bDMARD dose reduction and to provide answers to specific dose-reduction-related questions that are of interest to clinicians.MethodsWe systematically searched for relevant studies in four scientific databases. Furthermore, we screened the references of reviews and relevant studies.ResultsOur searches resulted in 45 original studies of bDMARD dose reduction in RA patients (15 RCTs and 30 observational studies). Current evidence shows that bDMARD dose reduction can be considered in all RA patients who achieve stable (e.g., ≥6 months) low disease activity or remission. The best strategies seem to be disease-activity-guided dose optimization and fixed dose reduction, since direct bDMARD discontinuation (without restarting) results in a high flare rate, worse physical functioning, and more joint damage. When tapering the bDMARD treatment of a patient, disease activity should be monitored closely, and if a flare occurs, the dose should be increased to the lowest effective dose. Current evidence shows that restarting bDMARD treatment is effective and safe. Unfortunately, no clear predictors of successful dose reduction have been identified so far.ConclusionThe current evidence and rising healthcare costs urge that dose reduction should be considered for eligible patients. However, the decision to start dose reduction should be made in shared decision-making. Future research should focus not only on a better understanding of the effects of dose reduction on clinical outcomes but also on the perspectives of patients and physicians as well as the implementation of this new treatment principle.

Project description:IntroductionMisclassification of spondyloarthritis (SpA) as rheumatoid arthritis (RA) may lead to delayed SpA diagnosis and suboptimal therapeutic outcomes. Here, we evaluate the literature on clinical manifestations in patients with SpA and RA, particularly seronegative RA, to understand the potential overlap, distinctions, and most reliable approaches to accurate diagnosis.MethodsIn this systematic literature review, conducted according to PRISMA guidelines, we searched key biomedical databases for English-language publications of original research articles (up to July 23, 2020) and rheumatology conference abstracts (January 1, 2018-July 31, 2020) reporting key SpA clinical presentations in patients with SpA or RA. Publications were assessed for eligibility by two independent reviewers; discrepancies were resolved by a third. Studies were evaluated for publication quality using the Downs and Black checklist.ResultsOf 4712 records retrieved, 79 met the inclusion criteria and were included in the analysis. Of these, 54 included study populations with SpA and RA, and 25 with seropositive and/or seronegative RA. Entheseal abnormalities were more frequently reported among patients with SpA than RA and with seronegative vs. seropositive RA. Psoriasis, nail psoriasis, and dactylitis were exclusively seen in SpA vs. RA. In most publications (70 of 79), advanced imaging techniques allowed for more accurate distinction between SpA and RA. Overlapping clinical characteristics occur in SpA and RA, including inflammation and destruction of joints, pain, diminished functional ability, and increased risk for comorbidities. However, of 54 studies comparing SpA and RA populations, only seven concluded that no distinction can be made based on the SpA manifestations and outcomes examined.ConclusionsTypical SpA-related clinical symptoms and signs were observed in patients with RA, suggesting that misclassification could occur. Availability of advanced imaging modalities may allow for more prompt and comprehensive evaluation of peripheral manifestations in SpA and RA, reducing misclassification and delayed diagnosis.

Project description:Purpose: Rheumatoid arthritis (RA) is a pervasive inflammatory autoimmune disease that seriously impairs human health and requires more effective non-pharmacologic treatment approaches. This study aims to systematically review and evaluate the efficacy of yoga for patients with RA. Methods: Medline (through PubMed), Cochrane Library, EMBASE (through SCOPUS), and Web of Science database were screened through for articles published until 20 July 2020. Randomized controlled trials (RCTs) of yoga in patients with RA were included. Outcomes measures were pain, physical function, disease activity, inflammatory cytokines, and grip strength. For each outcome, standardized mean differences (SMD) and 95% confidence intervals (CI) were calculated. Result: Ten trials including 840 patients with RA aged 30-70 years were identified, with 86% female participants. Meta-analysis revealed a statistically significant overall effect in favor of yoga for physical function (HAQ-DI) (5 RCTs; SMD = -0.32, 95% CI -0.58 to -0.05, I 2 = 15%, P = 0.02), disease activity (DAS-28) (4 RCTs; SMD = -0.38, 95% CI -0.71 to -0.06, I 2 = 41%, P = 0.02) and grip strength (2 RCTs; SMD = 1.30, 95% CI 0.47-2.13, I 2 = 63%, P = 0.002). No effects were found for pain, tender joints, swollen joints count or inflammatory cytokines (i.e., CRP, ESR, IL-6, and TNF-α). Summary: The findings of this meta-analysis indicate that yoga may be beneficial for improving physical function, disease activity, and grip strength in patients with RA. However, the balance of evidence showed that yoga had no significant effect in improving pain, tender joints, swollen joints count, and inflammatory cytokines in patients suffering from RA. Considering methodological limitations, small sample size, and low-quality, we draw a very cautious conclusion in the results of the estimate of the effect. High-quality and large-scale RCTs are urgently needed in the future, and the real result may be substantially different.
