IMBA Hutano: uptake and yield of screening, linkage and outcomes dataset – Data Codebook

Persistent identifier

10.17037/DATA.00004570

Description

Data collected as part of a nested sub-study within the ERASE-TB project to deliver an integrated health check to members of tuberculosis-affected households.  Data was collected at baseline through an interviewer-administered questionnaire and clinical screening, followed by linkage‑to‑care assessments obtained via telephone follow‑up and provider records, and a final assessment at 12‑month follow‑up. The dataset contains demographic, socio‑economic, behavioural, and clinical information for participants involved in the study (one row per participant), including results from screening for TB, HIV, diabetes, hypertension, vision impairment, mental health, as well as healthcare utilisation and costs.
