Factors associated with adherence of cervical cancer screening in women with Systemic Lupus Erythematosus.

OBJECTIVES: To determine cervical cancer screening rates and factors associated with decreased cervical cancer screening in women with systemic lupus erythematosus (SLE).

METHODS: We conducted a cross-sectional study that enrolled consecutive women (aged 21-64) with SLE. We collected demographics, clinical characteristics, constructs of the Health Beliefs Model (HBM) (i.e., susceptibility, severity, barriers, benefits, cues to action, and self-efficacy), and self-reported cervical cancer screening (confirmed with the electronic medical record). The primary outcome was adherence to cervical cancer screening according to current guidelines. Multivariable logistic regression models were used to examine the association between SLE disease activity and cervical cancer screening, and explore mediation effects from HBM constructs.

RESULTS: We enrolled 130 women with SLE. The median age was 42 (IQR 32-52). The cervical cancer screening adherence rate was 61.5%. Women with high SLE disease activity were less likely to have cervical cancer screening versus those with low disease activity (OR 0.59, 0.39-0.89, p=0.01), which remained statistically significant after adjusting for baseline demographics and drug therapy in a multivariable model (OR 0.25, 95% CI 0.08-0.79, p=0.02). Regarding the HBM constructs, increased perceived barriers to cervical cancer screening (r=-0.30, p < 0.01) and decreased self-efficacy (r=-0.21, p=0.02) correlated with decreased cervical cancer screening.

CONCLUSION: SLE patients with high disease activity undergo cervical cancer screening less frequently than those with low disease activated. Perceived barriers to cervical cancer screening are moderately correlated with decreased screening. These data highlight to need to develop strategies to increase cervical cancer screening in this high-risk patient population.
