Resource utilization for multidrug-resistant tuberculosis household contact investigations (A5300/I2003)
OBJECTIVE: To describe the resource utilization and operational challenges encountered when identifying and characterizing adult MDR-TB index cases and their HHCs.
DESIGN: Cross-sectional study of adult MDR-TB index cases and HHCs at 16 clinical research sites in eight countries. Site-level resource utilization was assessed with surveys.
RESULTS: Between October 2015 and April 2016, 308 index cases and 1018 HHCs were enrolled. Of 280 index cases with sputum collected, 94 were smear-positive (34%, 95%CI 28–39), and of 201 with chest X-rays, 87 had cavitary disease (43%, 95%CI 37–50) after a mean duration of treatment of 8 weeks. Staff required 512 attempts to evaluate the 308 households, with a median time per attempt of 4 h; 77% (95%CI 73–80) of HHCs were at increased risk for TB: 13% were aged <5 years, 8% were infected with the human immunodeficiency virus, and 79% were positive on the tuberculin skin test/interferon-gamma release assay. One hundred and twenty-one previously undiagnosed TB cases were identified. Issues identified by site staff included the complexity of personnel and participant transportation, infection control, personnel safety and management of stigma.
CONCLUSION: HHC investigations can be high yield, but are labor-intensive.
