Does Systemic Lupus Erythematosus Care Provided in a Lupus Clinic Result in Higher Quality of Care Than That Provided in a General Rheumatology Clinic?

Abstract

Objective: To compare the quality of care received by patients with systemic lupus erythematosus (SLE) in 2 settings within the academic institution (a dedicated lupus clinic and a general rheumatology clinic) using validated SLE quality measures. Methods: One hundred fifty consenting, consecutive SLE patients receiving longitudinal care at the Rush University general rheumatology clinic (n = 73) or the subspecialty lupus clinic (n = 77) were recruited. An updated quality measure survey and retrospective medical chart review were used to evaluate each quality measure (n = 20). The overall and individual quality measure performance was calculated and compared between the 2 groups. Data on the number of SLE patients seen by each rheumatologist were collected to assess the relationship between SLE patient volume and quality measures. Results: Overall quality measure performance was significantly better in SLE patients receiving care at the lupus clinic (85.8% versus 70.2% of patients receiving care at the general rheumatology clinic; P = 0.001). Differences between the 2 groups were observed for sunscreen counseling (98.7% and 83.6%, respectively; P = 0.001), antiphospholipid antibody testing (71.4% and 37%, respectively; P < 0.001), pneumococcal vaccination (84.8% and 48.8%, respectively; P < 0.001), bone mineral density testing (94.2% and 54.5%, respectively; P < 0.001), drug counseling (92.2% and 80.8%, respectively; P = 0.04), use of a steroid-sparing agent (100% and 82%, respectively; P < 0.007), use of an angiotensin-converting enzyme inhibitor (94.4% and 58.3%, respectively; P = 0.03), and cardiovascular disease risk assessment (40.3% and 15.1%, respectively; P = 0.01). There was a moderate correlation between physician volume and quality measure performance (ρ = 0.48, P < 0.001). Conclusion: Compared with the general rheumatology clinic, the dedicated lupus clinic had better quality measure performance in this cross-sectional single-center study. In our health care system, we also observed indicators suggesting that rheumatologists with a higher volume of SLE patients provide higher quality of care.
