Abstract
Purpose
The study aimed to determine data collected during tuberculosis (TB) contact investigations and to evaluate the outcomes of these investigations.
Methods
We reviewed medical records for child contacts of patients with culture-positive pulmonary TB aged 19 years or older between August 2012 and July 2014.
Results
A total of 116 child contacts were identified for 79 patients with culture—positive pulmonary TB. of 116 contacts identified, 22% were incompletely screened. Of 90 contacts who completed screening, 42% had negative tuberculin skin test (TST) results, 58% had positive results, and 1% had active pulmonary TB at the time of investigation. Of 50 contacts with TB patients with a negative smear, 50% had positive TST results. Age 25 years (OR 8.3; 95% CI 2.3-30) and male gender (OR 3.9; 95% CI 1.5—9.9) were significantly associated with being incompletely screened.
