Electronic health record decision support for the diagnosis and management of pediatric tuberculosis infection

ABSTRACT Objective To evaluate whether new tuberculosis (TB) tools in the electronic health record (EHR) can support latent TB infection (LTBI) screening, testing and treatment among children and adolescents in a primary care setting. Study Design This retrospective cohort study included children and adolescents between the ages 1-25 years who had a well-child or well-adolescent visit at a Federally Qualified Health Center in Oakland, California, from December 2021 to December 2022. Four new EHR tools were introduced for the completion and documentation of TB risk factor screening, testing and treatment. Data were extracted from the EHR to identify gaps in these steps, and logistic regression was used to examine factors associated with completion of TB infection screening and testing. Acceptability was evaluated using provider satisfaction surveys before and after the implementation of TB EHR tools. Results Of 5,879 individuals (median age of 9 years at first visit, interquartile range (IQR) 4-13 years), 94% completed TB risk factor screening. Among those with a new risk factor, 59% had a TB infection test ordered and 96% completed testing. Ten participants (3%) tested positive, all initiated LTBI treatment, and most (n=7, 70%) completed treatment. Overall, 5,162 (88%) individuals completed their LTBI care cascade. Younger children ages 1-4 years were more likely to be screened for TB risk factors, but were less likely to be tested. Provider satisfaction increased from 40% to 71% for risk factor screening, and 36% to 77% for test ordering. Conclusion EHR tools supported completion of the pediatric LTBI care cascade, while also increasing provider satisfaction. EHR-based solutions show promise as part of multi-component strategies to address gaps in LTBI care for children and adolescents.
