    Abstract:
    OBJECTIVE: To describe mandates and policy gaps in tuberculosis (TB) contact investigation and management. DESIGN: We conducted a systematic review of national TB policy documents obtained using a systematic internet search and by contacting national TB programs. We included policies published in English, Spanish, and French, and abstracted data using a standardized form. RESULTS: We reviewed policy documents for 68 of 216 (31%) countries and territories. All countries recommended performing contact investigations, but 40% did not specify how contacts enter the health system for evaluation or who was responsible for this process. All countries recommended preventive therapy for contacts, but in 14 (21%) countries only young children were eligible. While four preventive therapy regimens exist, 48 (71%) countries recommended only isoniazid monotherapy. In addition, 28 (41%) countries lacked guidance on whether to give preventive therapy to contacts exposed to drug-resistant TB. Policies in 28 (41%) countries lacked recommendations for managing contacts with the human immunodeficiency virus (HIV) after new TB exposure. CONCLUSION: Policies recommending contact investigation and preventive therapy for contacts are widespread, but policy gaps exist in the areas of ensuring accountability and the management of vulnerable populations such as people living with HIV and those exposed to drug-resistant TB.
