Plain English summary of protocol
Background and study aims
Millions of people around the world have survived tuberculosis (TB), but many still face serious health, emotional, and financial challenges even after treatment ends. In countries like South Africa and Cambodia, where TB is common and resources are limited, there is very little support for people after TB treatment. This study aims to improve care for TB survivors by understanding their needs and creating better support systems. Researchers will work with TB survivors, healthcare providers, and communities to develop tools, care packages, and a centre of excellence for post-TB care.
Who can participate?
People who have finished TB treatment and those who provide post-TB care are invited to take part in the study.
What does the study involve?
Participants will help researchers understand the physical, emotional, and financial effects of TB after treatment. This may include medical check-ups, interviews, and surveys. The study will also explore what kind of care and support TB survivors need and how best to provide it in places with limited resources.
What are the possible benefits and risks of participating?
Participants may benefit from thorough health assessments and help connecting with health and social services. The risks are similar to those of standard medical tests, and all procedures will be carried out by trained professionals under medical supervision.
Where is the study run from?
The study is led jointly by the London School of Hygiene and Tropical Medicine in the UK and Stellenbosch University in South Africa.
When is the study starting and how long is it expected to run for?
August 2024 to August 2028.
Who is funding the study?
National Institute for Health and Care Research (NIHR) in the UK.

| Scientific title | NIHR Global Health Research Group on post-tuberculosis care in high TB burden settings |
| Study acronym | POST-TB CARE |
| Study objectives | Aim: To improve post-TB care in high-burden, resource-limited settings Objective 1: Develop an operational multidimensional assessment tool, which can quantify impairment in TB survivors to accurately assess post-TB care needs. Objective 2: Design an effective, appropriate, and sustainable post-TB care package for resource-limited settings, using principles of good clinical governance. Objective 3: Create a knowledge sharing and advocacy platform for post-TB in high-burden TB settings. Objective 4: Develop a multi-disciplinary centre of excellence for post-TB research, care, and community engagement in South Africa to enable sustainable, collaborative south-south and north-south research partnerships in post-TB. |

| Health condition(s) or problem(s) studied | Post-tuberculosis disease |
| Intervention | To address Objective 1 (post-TB care needs assessment) and Objective 2 (post-TB care package) our Target Populations are TB survivors and post-TB care providers from South Africa and Cambodia, Settings where a high burden of post-TB care need (estimated 1 in 20 individuals are TB survivors), while facing limited human resources and near absent access to advanced medical tests). For Objective 1 (assessment) we will recruit a cohort of TB survivors and repeat the assessments over a period of 12 months to monitor changes in 1) post-TB care needs and 2) the association between reference standard and operational tools Data collection for Objective 1 will include repeated radiological, physiological and cardiopulmonary function assessment, as well as extended questionnaires to assess psychosocial and economic post-TB impairment, and how these change over 12 months. For objective 2 we will conduct qualitative interviews and Discrete Choice Experiments (DCE). Data analysis for data collected in work package 1 will include ROC curves/C-statistic and regression approaches, while predictive modelling will be used to identify a short list of the most informative questions for psychosocial and economic post TB assessment in these populations. Qualitative data from work package 2 will be analysed using deductive thematic analytic approaches, while DCEs will be analysed using Multinomial Logit and Latent Class models. To address Objective 3 (Knowledge sharing and advocacy platform) we will convene online and in-person meetings, targeting post-TB communities from high-burden settings across the world. Objective 4 (develop centre of excellence in post-TB research) we will strengthen the human and material infrastructure. |
