Title: Patient Outcomes, Preferences, & Attitudes Poster II: Measurements (0739–0763)

Session Type: Poster Session B

Session Time: 8:30AM-10:30AM

Background/Purpose: Patients with SLE have significantly worse health-related quality of life (QOL) at an earlier age compared to patients with other chronic diseases. This highlights the importance of measuring and addressing patient-reported outcomes (PROs) to improve outcomes and QOL in SLE. Yet, QOL tools are lengthy and offer limited guidance to clinicians on use to impact disease-related outcomes in SLE. There is a need to improve feasibility such as using global short-form QOL measures. Therefore, we examined the feasibility of collecting global and lupus specific QOL measures in an academic SLE center and their correlation with disease-related outcomes.

Methods: Our study included all consecutive SLE follow-up visits at the UW SLE Clinic between 3/2019-5/2021. At each visit: 1) patients completed both the Patient Reported Outcome Measure Information System (PROMIS) Global Short Form and the LupusQOL; 2) physicians completed SLE disease activity index (SLEDAI) and SLICC-ACR damage index (SLICC DI). We calculated Pearson’s correlation between PROMIS – Global physical and mental health scores, and LupusQOL domain scores and a total LupusQOL score. Next, we tested correlation between SLEDAI and PROMIS – global physical and mental health scores and LupusQOL domain and total scores, and SLICC-DI and both QOL scores.

Results: Between 1/1/19-4/1/21, there were 250 consecutive follow-up patient-visits of 75 patients with confirmed SLE at our clinic. Patients (Table 1) were 93% female, 69% White, and mean age at SLE diagnosis was 37 years. We noted that LupusQOL was completed in 106 patient visits (43%), PROMIS – Global was completed in 100 patient visits (40%), and SLEDAI, SLICC-DI completion rates were each 72%.

We found moderate correlation between both PROMIS-Global physical and mental health scores and total LupusQOL domain score (r = 0.55, p < 0.001; r = 0.52, p < 0.001) (Table 2). Further, PROMIS-Global physical health scores had moderate correlation with LupusQOL pain (r = 0.56, p < 0.001) and physical health (0.60, p < 0.001) domains (Table 2). While PROMIS-Global mental health scores only moderately correlated with all LupusQOL domains except the burden domain. Next, we noted statistically significant correlation between high SLEDAI and low total LupusQOL scores (r = -0.31, p 0.0029), low LupusQOL emotional health scores (r = -0.30, p 0.004) and low LupusQOL fatigue scores (r=-0.31, p 0.002) (Table 3). We noted statistically significant but low correlation between high SLICC-DI and low LupusQOL pain score (r = -0.30, p 0.0023) (Table 3.). No correlations were noted between PROMIS and SLEDAI, and PROMIS and SLICC-DI.

Conclusion: Our findings highlight that specific LupusQOL domains correlate with disease-related outcomes which could be targeted in busy clinical settings to improve QOL. Further, the PROMIS global short-form moderately correlates with key LupusQOL domains thus, this could be utilized in busy practices to assess QOL. Given a moderate QOL completion rate, future studies are required to develop short, actionable tools to incorporate key specific LupusQOL domains that correlate with disease scores to improve disease and patient outcomes in SLE.

All abstracts accepted to ACR Convergence are under media embargo once the ACR has notified presenters of their abstract’s acceptance. They may be presented at other meetings or published as manuscripts after this time but should not be discussed in non-scholarly venues or outlets. The following embargo policies are strictly enforced by the ACR.

Accepted abstracts are made available to the public online in advance of the meeting and are published in a special online supplement of our scientific journal, Arthritis & Rheumatology. Information contained in those abstracts may not be released until the abstracts appear online. In an exception to the media embargo, academic institutions, private organizations, and companies with products whose value may be influenced by information contained in an abstract may issue a press release to coincide with the availability of an ACR abstract on the ACR website. However, the ACR continues to require that information that goes beyond that contained in the abstract (e.g., discussion of the abstract done as part of editorial news coverage) is under media embargo until 10:00 AM ET on November 14, 2024. Journalists with access to embargoed information cannot release articles or editorial news coverage before this time. Editorial news coverage is considered original articles/videos developed by employed journalists to report facts, commentary, and subject matter expert quotes in a narrative form using a variety of sources (e.g., research, announcements, press releases, events, etc.).

Violation of this policy may result in the abstract being withdrawn from the meeting and other measures deemed appropriate. Authors are responsible for notifying colleagues, institutions, communications firms, and all other stakeholders related to the development or promotion of the abstract about this policy. If you have questions about the ACR abstract embargo policy, please contact ACR abstracts staff at [email protected].
