To understand the impact of extrapulmonary tuberculosis (EPTB) and its treatment on quality of life, we analysed patient-reported outcome measures (PROMs) among presumptive ETPB patients. EuroQol’s five-dimensional three-level (EQ-5D-3L) questionnaire and the Visual Analogue Scale (EQ-VAS) were used to measure PROMs by 274 presumptive EPTB patients at pre- and post-treatment stages. The patients were categorised as TB and non-TB by using a composite reference standard. Following the EuroQol suggested analysis methods, we calculated the health utility summary measure at the pre- and post-treatment stages. The health state density curve and index were used to analyse inequality in reported health profiles. We investigated factors associated with EPTB patients’ health utility through multivariable regression at the pre-treatment stage. The analysis of PROMs showed both physical (mobility, self-care, usual activities) and psychological (pain, discomfort, anxiety & depression) health affected by all EPTB manifestations (lymphadenitis, pleuritis, meningitis and others). Moreover, we found inequality in reported health profiles across disease manifestations at pre- and post-treatment stages. Post-treatment, we found improvement in PROMs and no reports of extreme-level health problems. However, some problems persisted across all dimensions of EPTB manifestations. We found 100% improvement in pleuritis and meningitis manifestations. Socioeconomic status, type of health facility attended, and patients’ working capacity were associated with health utility. Despite post-treatment improvement in health, inequality of reported health states by EPTB manifestations persisted, though decreased. This highlights that holistic patient- and health system-level interventions addressing the impact of illness should consider EPTB by its manifestations, not as a single disease entity.
