Abstract

Abstract : Objective: Immunomodulatory therapies improve the management of chronic diseases but can be associated with infectious risk. The present study was undertaken to examine the laboratory screening practices for hepatitis B virus (HBV), hepatitis C virus (HCV), and tuberculosis (TB) and rates of vaccination for pneumococcal and influenza in patients prescribed select immunosuppressive agents at our institution. Methods: A retrospective analysis was conducted to review patients who were prescribed a select immunosuppressive over 3 years. Data were extracted from electronic health records to identify rates of screening and vaccination prior to initiation or at any time. Logistic regression models were developed to identify predictors of screening and vaccination. Results: We identified 2, 396 patients prescribed immunosuppressive medications by rheumatology (52.6%) and non‐rheumatology specialties. Rates of screening at any time point were 84.5% (2, 025 of 2, 396) for HBV, 76.7% (1, 838 of 2, 396) for HCV, and 71.8% (1, 720 of 2, 396) for TB. Patients who had either in‐system primary care providers (PCPs) or rheumatologists were more likely to receive pneumococcal vaccinations (odds ratio [OR] 1.98 [95% confidence interval (95% CI) 1.55–2.54] and OR 4.08 [95% CI 2.76–6.02], respectively). Patients with dermatologic (OR 1.67 [95% CI 1.14–2.45]) or rheumatologic providers (OR 2.5 [95% CI 1.86–3.36]) were more likely to be vaccinated for influenza. Conclusion: More than 70% of patients were screened for either HBV, HCV, or TB at some point. Rates of pneumococcal vaccination were better than rates of influenza vaccination. Patients with in‐system PCPs were more likely to be screened and vaccinated. Establishing and executing consistent processes for screening and vaccination prior to immunosuppressive treatment remains a priority in ambulatory settings.
