Increasing use of interferon gamma release assays among children ≥2 years of age in a setting with low tuberculosis prevalence.
This article describes a retrospective cohort study that examined interferon gamma release assays (IGRAs) use to diagnose tuberculosis (TB) infection in children aged 2–17. The objectives of the study were to evaluate whether testing approaches for TB has changed since 2015. Electronic health records were used to identify IGRAs and tuberculin skin tests (TSTs) completed by children in two Boston-area academic health systems. The researchers observed that the proportion of IGRA tests increased between 2015 and 2021 in this low TB-prevalence setting. Testing in public versus private insurance, inpatient/subspecialty settings, lower age, and non-English preferred language were associated with an increased chance of receiving an IGRA. Findings suggest that the TST is being “retired,” and that education and support for primary care clinicians could improve equitable access to IGRA testing for children.

Testing and scaling interventions to improve the tuberculosis infection care cascade.
The purpose of this study was to review and summarize current literature on barriers and solutions occurring within the tuberculosis (TB) infection care cascade, focusing on children in high- and low-burden settings, and obtaining data and information from studies on both children and adults. The researchers concluded that identifying and addressing gaps in the TB care cascade requires the utilization of tools both novel and long-standing, and will be facilitated by shared clinical practice with primary care providers, methods of quality improvement, and innovative study designs.

A risk model to identify Legionella among patients admitted with community-acquired pneumonia: a retrospective cohort study.
This study’s goal was to derive and externally validate a model to predict a positive Legionella test among adult inpatients diagnosed with pneumonia. The study used data from 177 US hospitals in the Premier Healthcare Database and 12 Cleveland Clinic Health System (CCHS) hospitals. Of 166,689 patients hospitalized for pneumonia, out of 43,070 tested for Legionella 642 (1.5%) tested positive. The strongest predictors of a positive test were a local outbreak, June-October occurrence, hyponatremia, smoking and diarrhea. A negative test was associated with prior admission within 6 months and chronic pulmonary disease.
