Improving Latent Tuberculosis Infection (LTBI) Screening and Treatment in a School-Based Setting

Background: San Diego County’s tuberculosis (TB) incidence rate is nearly double than the national rate. In 2019, there have been 5 cases of active TB in the county’s public high schools, which have demonstrated the need for prevention interventions in this setting. Objectives: This evidence-based project is aimed to increase awareness, screening and treatment of latent TB infection (LTBI) in the school setting. Methods: A TB risk assessment form and consent was sent in the registration packets. A one-time TB educational presentation was given to high school freshman students with a pretest and posttest. For students at-risk, a confidential package was mailed out to parents recommending testing along with a letter to the child’s provider offering the option of rifapentine and isoniazid (3HP) to be given at school. Incentives were provided throughout the program. Results: Following an educational intervention, there was an 18% increase. Out of the 243 Freshman cluster students, 92 (38%) of forms were returned. Approximately 68% of students were found to be at risk. Conclusions: Like the pilot project, there was a low return of TB risk assessments but a high percentage of students at risk. Future assessments will be needed to determine improving screening efforts
