Summary: Tuberculosis (TB) elimination in the United States hinges on large-scale TB screening, testing, and preventive treatment of individuals at risk for TB disease. However, the path from TB screening to TB preventive therapy (TPT) completion is not straightforward and relies on collaboration between public health departments and primary care providers to deliver quality TB services. To address a gap in primary care guidance on how to manage a patient who is asymptomatic and TB screening test–positive with abnormal chest imaging, NEMS and the San Francisco Department of Public Health TB Clinic, with support from the California Department of Public Health and UCSF as partners, collaborated to utilize both provider education and radiology, laboratory, and electronic health record (EHR) systems modifications as decision aids for TB risk stratification of patients. Through this multipronged approach, NEMS simplified TB prevention workflows for primary care providers and streamlined the provider decision-making process to refer patients at higher risk for developing TB disease to the TB clinic.
