Insights

The New York City Department of Health (NYCDOH) tuberculosis risk assessment questionnaire effectively identifies children needing a tuberculin skin test. This targeted screening improves efficiency and accuracy in pediatric tuberculosis detection.

Area of Science:

  • Pediatric Public Health
  • Infectious Disease Epidemiology
  • Diagnostic Test Evaluation

Background:

  • Universal tuberculin skin testing in children is often inefficient and costly.
  • Targeted screening based on epidemiological risk is recommended by health authorities.
  • The New York City Department of Health (NYCDOH) developed a risk assessment questionnaire to identify children requiring testing.

Purpose of the Study:

  • To evaluate the sensitivity, specificity, and predictive validity of the NYCDOH tuberculosis risk assessment questionnaire.
  • To determine the effectiveness of targeted screening for pediatric tuberculosis.

Main Methods:

  • A prospective criterion standard study was conducted involving 2920 children aged 1-18 years.
  • Tuberculin skin tests and the NYCDOH questionnaire were administered simultaneously.
  • Key questions focused on tuberculosis case contact, endemic area travel/birth, high-risk adult contact, and HIV status.

Main Results:

  • The NYCDOH questionnaire identified 14% of children with at least one risk factor.
  • A positive skin test occurred in 5.6% of children with risk factors versus 0.16% without.
  • The questionnaire demonstrated 85.2% sensitivity, 86.0% specificity, and a 99.8% negative predictive value.

Conclusions:

  • The NYCDOH questionnaire is a validated tool for identifying children who require tuberculin skin testing.
  • Targeted screening using this questionnaire enhances the efficiency of pediatric tuberculosis detection.
