Objective: To characterize problems with prevention and management of pediatric tuberculosis (TB) and latent TB infection (LTBI).
Design: A multisite, cross-sectional study using data from medical records and public health logs to categorize and define use of routine prevention practices in managing pediatric TB and LTBI.
Setting: Four areas of the United States.
Participants: Children younger than 5 years diagnosed with TB from January 1, 2002, through December 31, 2004, and children with LTBI reported during a continuous 12-month period in 2003 to 2004.
Main Exposure: Mycobacterium tuberculosis.
Main Outcome Measures: Underuse or nonuse of standard medical and public health interventions.
Results: Almost 40% of children had a TB risk factor related to their country of birth, parental origin, or travel to a country with a high incidence of TB. Children having LTBI were less likely than those having TB to complete treatment (53.7% vs 88.6%, respectively). Almost half (46.3%) of the children with TB came to medical attention late in their course when they already had symptoms. Among 63 adult source patients, 19 (30.2%) previously had LTBI but were not treated, and none of the 40 foreign-born source patients were known to have been evaluated for TB before entry into the United States.
Conclusions: Prevention efforts are unsatisfactory to prevent TB in children. Effective interventions such as treatment of LTBI and TB evaluation of adult immigrants remain less than optimal.
