Objectives: To determine the incidence of mortality and its predictors among pulmonary tuberculosis (PTB) survivors treated at a rural Ugandan tertiary hospital.
Methods: We conducted a retrospective chart review of data between 2013 and 2023. We included all people that met the World Health Organisation's definition of tuberculosis cure and traced them or their next of kin to determine vital status (alive/deceased). We estimated the cumulative incidence of mortality per 1000 population, crude all-cause mortality rate per 1000 person-years, and median years of potential life lost for deceased individuals. Using Cox proportional hazard models, we investigated predictors of mortality.
Results: Of 334 PTB survivors enrolled, 38 (11.4%) had died. The cumulative incidence of all-cause mortality was 113.7 per 1000 population, and the crude all-cause mortality rate was 28.5 per 1000 person-years. The median years of potential life lost for deceased individuals was 23.8 years (IQR: 9.6-32.8). Hospitalization (adjusted hazard ratio (aHR): 4.3, 95% CI: 1.1-16.6) and unemployment (aHR: 7.04, 95% CI: 1.5-31.6) at TB treatment initiation predicted mortality.
Conclusion: PTB survivors experience post high mortality rates after TB cure. Survivors who were hospitalized and unemployed at treatment initiation were more likely to die after cure. Social protection measures and long-term follow-up of previously hospitalized patients could improve the long-term survival of TB survivors.

Respiratory symptoms after TB treatment completion: A qualitative study of patient and provider experiences in urban Blantyre, Malawi.
PLOS Glob Public Health
September 2024
Department of Health, Ethics & Society, Maastricht University, Maastricht, Netherlands.
Article Synopsis
- PTB survivors face ongoing respiratory issues after treatment, leading to anxiety and uncertainty about seeking further care.
- In-depth interviews and focus groups revealed that there is limited counseling for patients and no clear pathways for returning to healthcare services post-treatment.
- The study emphasizes the need for improved guidelines and practices to enhance the care of TB-survivors, as current approaches may contribute to missed diagnoses and public health risks.

Introduction: Pulmonary tuberculosis (PTB) remains a life-threatening disease in Tanzania, with negative physical, financial, economic and psychosocial consequences to individuals and the society. It mainly lowers the quality of life of patients, survivors and their families, especially those in the poorest and socially deprived categories.
Objectives: To report and discuss a qualitative study that assessed the nature of social support desired and received by PTB patients and survivors.

Post-tuberculosis respiratory impairment in Gambian children and adolescents: A cross-sectional analysis.

Article Synopsis
- - The study investigated the prevalence of post-tuberculosis lung disease (PTLD) among children and adolescents in The Gambia, focusing on survivors of pulmonary tuberculosis (pTB).
- - Out of 79 participants, a significant number experienced respiratory issues after treatment, including cough and abnormal lung function as indicated by chest X-rays (CXR) and spirometry tests.
- - Factors like age at diagnosis, undernutrition, and lung fibrosis were linked to poorer lung function, highlighting the need for ongoing monitoring and evaluation post-TB treatment to enhance patient outcomes.
Screening for post-TB lung disease at TB treatment completion: Are symptoms sufficient?

Pulmonary TB survivors face a high burden of post-TB lung disease (PTLD) after TB treatment completion. In this secondary data analysis we investigate the performance of parameters measured at TB treatment completion in predicting morbidity over the subsequent year, to inform programmatic approaches to PTLD screening in low-resource settings. Cohort data from urban Blantyre, Malawi were used to construct regression models for five morbidity outcomes (chronic respiratory symptoms or functional limitation, ongoing health seeking, spirometry decline, self-reported financial impact of TB disease, and death) in the year after PTB treatment, using three modelling approaches: logistic regression; penalised regression with pre-selected predictors; elastic net penalised regression using the full parent dataset.
