Abstract
Introduction: Heterogeneity of the clinical manifestations of systemic lupus erythematosus (SLE) may lead to diagnostic delays. This study is aimed at determining the health-seeking behaviour patterns and factors associated with diagnostic delays in a multi-ethnic SLE cohort in Malaysia.
Methodology: This was a cross-sectional study involving SLE patients who visited our institute between January 2020 and June 2021. A review of the medical records and face-to-face interviews were conducted to obtain sociodemographics, SLE disease characteristics and the intervals from the first symptoms to the diagnosis. Health-seeking behaviours were assessed by asking about the patients' first action during the initial symptoms and were divided into: (i) seeking professional health personnel; (ii) self-treatment; and (iii) the use of the internet as a primary source of information. Diagnostic delays were defined as the interval between initial symptoms and SLE diagnosis of more than 6 months. Low-level disease activity state (LLDAS) at 12 months was assessed from the medical records. Univariate and multivariate logistic regression analysis was subsequently conducted to determine factors associated with diagnostic delays.
Results: Among the 154 patients included in the study, 24% (n = 37) had delayed diagnosis. The delay was significantly higher among the Indian versus Malay versus Chinese (42.9% vs 28% vs 10.8%, p = 0.037). Patients with rash tend to have delayed diagnosis (37.8% vs 22.2%, p = 0.08) while fewer patients with frothy urine had delayed diagnosis (8.1% vs 21.4%, p = 0.09). No significant association was found between health-seeking behaviours and diagnostic delays. The rate of LLDAS at 12 months was significantly lower among patients with delayed diagnosis (43.2% vs 70.0%, p = 0.006). Chinese ethnicity remained the only significant factor associated with lesser diagnostic delays in the multivariate analysis, with OR 0.30 (CI 0.09-0.93), p = 0.037.
Conclusion: There were ethnic disparities in the early diagnosis of SLE in Malaysia, with Indian patients having a longer interval between the first symptom and diagnosis while the Chinese were associated with lower diagnostic delays. Early diagnosis predicted early attainment of LLDAS, suggesting that prompt recognition of the initial SLE symptoms is important.
