Safety screening completion in patients initiating immune response mediator therapy for rheumatology, dermatology, and gastroenterology conditions: A multisite prospective analysis

1 Study Overview

1.1 Background

Despite the recommendation that patients initiating immune response mediator therapies for chronic autoimmune conditions be screened for tuberculosis (TB) and hepatitis B virus (HBV) prior to initiation, previous studies have found low screening rates.

This analysis assessed TB and HBV screening completion rates at the time of immune response mediator initiation and reasons for incomplete screening in health-system specialty pharmacies.

1.2 Methods

Multi-site (12 sites), prospective, observational cohort study.

Inclusion: Adult patients initiating a medication with risk for TB or HBV reactivation indicated for a rheumatology, dermatology, or gastroenterology condition between March 1 and May 31, 2023.

Exclusion: Biologic medication use within 1 year prior to index referral date, referral from a non-health system provider, lost to follow-up before screening or treatment initiation.

1.3 Outcomes

Rate of complete screening (defined as completing both TB and HBV screening) and rate and timing of TB screening and HBV screening.
