Ab0474 impact of health literacy on trust in physicians among patients with systemic lupus erythematosus: the trump2-sle project

BackgroundInformation technology has expanded the gap in patient health literacy (HL), and HL has various implications on the trust in patient-doctor relationship. Previously, only functional HL, the ability to interpret health information through reading and writing skills, has been studied in patients with SLE (1).ObjectivesWe examined how trust in physicians is affected by the broader concept of HL, including communicative HL, the ability to extract health information from communication to use, and critical HL, the ability to discern and use such information (2).MethodsThis cross-sectional study enrolled 362 SLE patients at 5 sites between June 2020 and August 2021. Three domains of HL (i.e., functional HL, communicative HL, and critical HL) were assessed using the 14-item FCCHL scale (range: 1-4 points for each domain). The outcomes were patients’ trust in their physicians and physicians in general and were measured using the Japanese version of the 5-item Wake Forest Physician Trust scales (range: 0-100 points for each scale). General linear models adjusted for age, gender, education, income, SLEDAI, disease duration, depression, and hours of Internet use were conducted. Subsequently, a series of general linear models were then fit to each of the three domains of HL to examine whether or not it was associated with the aforementioned covariates.ResultsThe median age of the patients was 45 (interquartile range [IQR],34-55), 88% were female. The median value of SLEDAI was 4 ([IQR], 2-8), Trust in one’s physician was 80 ([IQR], 70-95) and trust in physicians generally was 65 ([IQR], 50-80). Trust in one’s physician increased with higher functional and communicative HL (per 1-pt increase, 3.2 [95%CI 0.7 to 5.9]; 5.4 [95%CI 1.6 to 9.3]). Trust in doctors generally increased with higher communicative HL and decreased with higher critical HL (per 1-pt increase, 6.8 [95% CI 2.0 to 12]; -6.7 [95% CI -12 to -1.9]). Lower functional HL was associated with older age and depression, while higher HL was associated with higher educational level. Higher communicative HL and critical HL were each associated with longer Internet use.ConclusionIn patients with SLE, higher trust in one’s physician was associated with both functional and communicative HL, while higher trust in physicians generally was associated with higher communicative HL and lower critical HL. Our findings suggest that trusting relationships may be fostered by the encouragement of rheumatologists to cultivate patients’ ability to share their health problems with their physicians and family members and to obtain useful health information (i.e., communicative HL), rather than to improve their ability to discern health information (i.e., critical HL).References[1]Maheswaranathan M, Cantrell S, Eudy AM, Rogers JL, Clowse MEB, Hastings SN, et al.
