Gaps in Addressing Cardiovascular Risk in Rheumatoid Arthritis: Assessing Performance Using Cardiovascular Quality Indicators.

OBJECTIVE: Cardiovascular disease (CVD) is a major comorbidity for patients with rheumatoid arthritis (RA). This study sought to determine the performance of 11 recently developed CVD quality indicators (QI) for RA in clinical practice. METHODS: Medical charts for patients with RA (early disease or biologic-treated) followed at 1 center were retrospectively reviewed. A systematic assessment of adherence to 11 QI over a 2-year period was completed. Performance on the QI was reported as a percentage pass rate. RESULTS: There were 170 charts reviewed (107 early disease and 63 biologic-treated). The most frequent CVD risk factors present at diagnosis (early disease) and biologic start (biologic-treated) included hypertension (26%), obesity (25%), smoking (21%), and dyslipidemia (15%). Performance on the CVD QI was highly variable. Areas of low performance (< 10% pass rates) included documentation of a formal CVD risk assessment, communication to the primary care physician (PCP) that patients with RA were at increased risk of CVD, body mass index documentation and counseling if overweight, communication to a PCP about an elevated blood pressure, and discussion of risks and benefits of antiinflammatories in patients at CVD risk. Rates of diabetes screening and lipid screening were 67% and 69%, respectively. The area of highest performance was observed for documentation of intent to taper corticosteroids (98%-100% for yrs 1 and 2, respectively). CONCLUSION: Gaps in CVD risk management were found and highlight the need for quality improvements. Key targets for improvement include coordination of CVD care between rheumatology and primary care, and communication of increased CVD risk in RA.

Development of Cardiovascular Quality Indicators for Rheumatoid Arthritis: Results from an International Expert Panel Using a Novel Online Process.

OBJECTIVE: Patients with rheumatoid arthritis (RA) have a high risk of premature cardiovascular disease (CVD). We developed CVD quality indicators (QI) for screening and use in rheumatology clinics. METHODS: A systematic review was conducted of the literature on CVD risk reduction in RA and the general population. Based on the best practices identified from this review, a draft set of 12 candidate QI were presented to a Canadian panel of rheumatologists and cardiologists (n = 6) from 3 academic centers to achieve consensus on the QI specifications. The resulting 11 QI were then evaluated by an online modified-Delphi panel of multidisciplinary health professionals and patients (n = 43) to determine their relevance, validity, and feasibility in 3 rounds of online voting and threaded discussion using a modified RAND/University of California, Los Angeles Appropriateness Methodology. RESULTS: Response rates for the online panel were 86%. All 11 QI were rated as highly relevant, valid, and feasible (median rating ≥ 7 on a 1-9 scale), with no significant disagreement. The final QI set addresses the following themes: communication to primary care about increased CV risk in RA; CV risk assessment; defining smoking status and providing cessation counseling; screening and addressing hypertension, dyslipidemia, and diabetes; exercise recommendations; body mass index screening and lifestyle counseling; minimizing corticosteroid use; and communicating to patients at high risk of CVD about the risks/benefits of nonsteroidal antiinflammatory drugs. CONCLUSION: Eleven QI for CVD care in patients with RA have been developed and are rated as highly relevant, valid, and feasible by an international multidisciplinary panel.

Best practices for cardiovascular disease prevention in rheumatoid arthritis: a systematic review of guideline recommendations and quality indicators.

OBJECTIVE: Cardiovascular disease (CVD) is a leading cause of mortality in rheumatoid arthritis (RA). This study systematically reviewed and appraised guidelines and quality indicators (QIs) pertaining to CVD risk management in patients with RA. METHODS: Four electronic medical databases (Medline, Embase, CINAHL, and Web of Science) and gray literature publications were searched using terms and keywords pertaining to guidelines, QIs, RA, and CVD (RA and general population literature searched). Abstracts were screened for inclusion and rated using the Appraisal of Guidelines for Research and Evaluation II instrument independently by 2 of 3 reviewers. RESULTS: In total, 16,064 abstracts were screened and 808 underwent full-text review. A total of 17 guidelines and 3 QI sets published between 2008 and 2013 were included. A number of consistent themes emerged, including the increased CV risk faced by RA patients and the need to address modifiable risk factors on a regular basis. The role of the multidisciplinary team in risk optimization was also highlighted. Ten guidelines provided recommendations for CVD prevention in patients with RA. Unfortunately, most recommendations lacked the specificity required to determine adherence to the recommendation. Only 4 RA-specific CVD QIs were identified (1 general comorbidity screening, formal CVD risk estimation, exercise, and minimizing steroid use). CONCLUSION: Regular screening for CVD risk factors is an important part of care in patients with RA. Unfortunately, existing RA-specific CVD QIs do not adequately address risk factor management, and existing guideline recommendations lack specificity for measurement and use in quality improvement initiatives.

Neurological complications of infliximab.

The use of anti-tumor necrosis factor-a (TNF-a) therapies has led to improved outcomes in the treatment of rheumatoid arthritis (RA). However, the use of these new therapeutic agents requires careful monitoring for adverse effects. We describe 3 patients who developed neurological disease closely associated with the use of infliximab, a monoclonal antibody that binds to and inactivates TNF-a. All had evidence of polyneuropathy, demyelinating in one and axonal in 2. One patient had a central nervous system syndrome. Physicians should be aware of these potential adverse effects when treating patients with infliximab.

Autoantibodies to tissue transglutaminase in Sjögren's syndrome and related rheumatic diseases.

OBJECTIVE: Sjögren's syndrome (SS) has been reported in up to 15% of patients with biopsy proven celiac disease (CD). The diagnosis of CD in the setting of SS and other systemic rheumatic diseases can be difficult because they are often associated with a number of gastrointestinal symptoms and diseases. Although the diagnosis of CD is often confirmed by a small bowel biopsy, marker autoantibodies directed against the endomysium of transitional epithelium (EMA) and tissue transglutaminase (tTG) are highly correlated with biopsy-proven disease and serve as a valuable screening test. We used an IgA-anti-tissue transglutaminase antibody (anti-tTG) ELISA to assess the prevalence of anti-tTG in an unselected cohort of patients with SS and other systemic rheumatic diseases. METHODS: Sera from 50 patients with SS, 50 with systemic lupus erythematosus (SLE), 50 with rheumatoid arthritis (RA), 30 with systemic sclerosis (SSc), and 50 healthy controls were tested for autoantibodies to tTG. A comparison group of 40 sera from patients with biopsy-confirmed CD was also included. IgA anti-tTG was measured by a commercially available ELISA kit (Inova, San Diego, CA) that employs purified tTG. RESULTS: Six of the 50 (12%) IgA sufficient SS patients had anti-tTG compared to 2 (4%) normal sera, 3 (6%) SLE, 2 (7%) SSc, and 1 (2%) RA. By comparison, in the CD cohort, 33 (83%) had anti-tTG. Five of 6 SS patients with anti-tTG had symptoms, signs, or small bowel biopsy findings consistent with a diagnosis of CD. IgA anti-tTG and EMA were accompanied by other IgA autoantibodies in SS sera. CONCLUSION: Anti-tTG ELISA is a reliable method to indicate a coexisting diagnosis of CD in patients with SS. Interestingly, the frequency of false positive tTG tests in any of the systemic rheumatic diseases is not significantly greater than in controls. Further, our study shows that anti-tTG is more prevalent in SS than in other systemic rheumatic diseases. The tTG ELISA may be used as a screening test to identify patients with SS who are at risk and require further evaluation for the presence of CD.
