Title: Patient Outcomes, Preferences, and Attitudes Poster I

Session Type: Poster Session A

Session Time: 1:00PM-3:00PM

Background/Purpose: In recent years, one of the overarching principles of EULAR recommendation is that systemic lupus erythematosus (SLE) treatment should be based on shared decision-making (SDM) between patients and physicians. However, it is unclear whether the degree of involvement of SLE patients in SDM contributes to their level of trust in their physicians. In this multicenter study, we investigated the relationship between the degree of involvement in SDM and the level of trust in physicians.

Methods: We collected data on the SDM-Q-9 shared decision-making scale (range 0-100), the Trust in Physician scale (TIPS; range 0-100), the Abbreviated Wake Forest Physician Trust Scale (A-WFPTS) for interpersonal trust in a physician (range 0-100), and the A-WFPTS for trust in the medical profession (range 0-100), in SLE patients aged 20 years or older who met the 1997 ACR revised classification criteria and were attending five facilities in Japan. We cross-sectionally examined the association between the SDM-Q-9 and each trust scale. In multiple regression analysis, we used age, sex, disease duration, SLE disease activity index, annual income, level of education, and marital status as adjusting variables, and missing values were complemented by multiple imputations.

Results: A total of 386 SLE patients (age 46.2 ± 14.3 years, 88.3% female) completed the questionnaire of this study. The SDM-Q-9 was positively correlated with three trust scales, TIPS, A-WFPTS for interpersonal trust in a physician, and A-WFPTS for trust in the medical profession (Spearman rank correlation coefficient r_s = 0.64 [95%CI 0.57-0.70], p < 0.0001, r_s = 0.69 [95%CI 0.63-0.74], p < 0.0001, and r_s = 0.47 [95%CI 0.39-0.55], p < 0.0001, respectively). When 351 patients who did not have missing data in SDM-Q-9 and TIPS were divided into two groups, the higher SDM group (185 patients, median 87 [IQR 80-96]) and the lower SDM group (166 patients, 60 [51-67]), the higher SDM group had significantly higher TIPS than the lower SDM group (75 [68-82] vs. 66 [59-68], p < 0.0001). Multiple regression analysis showed that TIPS increased by 2.74 (95%CI 2.32-3.15, p < 0.001) for every ten increases in SDM-Q-9. Similarly, a multiple regression analysis of 366 patients who did not have missing data in SDM-Q-9 and A-WFPTS for interpersonal trust in a physician showed that A-WFPTS increased by 5.08 (95%CI 4.40-5.75, p < 0.001) for every ten increases in SDM-Q-9. Multiple regression analysis of 369 patients who did not have missing data in SDM-Q-9 and A-WFPTS for trust in the medical profession showed that A-WFPTS increased by 4.24 (95%CI 3.30-5.19, p < 0.001) for every ten increases in SDM-Q-9.

Conclusion: The degree of involvement of SLE patients in SDM was associated with their trust in their physicians and doctors in general.
