Grit personality of physicians and achievement of treatment goals in patients with system lupus erythematosus

Objectives: Although personality characteristics of patients with SLE affect their disease activity and damage, it is unclear whether those of attending physicians affect the outcomes of patients with SLE. Grit is a personality trait for achieving long-term goals that may influence the decision-making for continuing treatment plans for patients. We aimed to evaluate the relationship between the grit of attending physicians and achievement of treatment goals in patients with SLE.

Methods: This cross-sectional study was conducted at five referral hospitals. The main exposure was 'consistency of interest' and 'perseverance of effort' of the attending physicians, measured by the Short Grit Scale. The primary outcome was achievement of a lupus low disease activity state (LLDAS). The association between physicians' grit score and LLDAS was analysed by generalized estimating equation (GEE) logistic regression with cluster robust variance estimation, with adjustment for confounders.

Results: The median (interquartile range) total, consistency and perseverance scores of 37 physicians were 3.1 (2.9-3.6), 3.3 (2.8-3.8) and 3.3 (3.0-3.5), respectively. Among the 386 patients, 154 (40%) had achieved LLDAS. Low consistency score (≤2.75) in physicians was related to LLDAS achievement independently using GEE logistic regression. The score of the question 'I often set a goal but later choose to pursue a different one' was significantly higher in patients achieving LLDAS.

Conclusions: Difficulty of attending physicians to change treatment goals might be related to lower LLDAS achievement in patients with SLE.
