Geographic accessibility to health facilities predicts uptake of community-based tuberculosis screening in an urban setting.

Objectives: Annually, more than 30% of individuals with tuberculosis (TB) remain undiagnosed. We aimed to assess whether geographic accessibility measures can identify neighborhoods that would benefit from TB screening services targeted toward closing the diagnosis gap.

Methods: We used data from a community-based mobile TB screening program in Carabayllo district, Lima, Peru.
