RESUMO
SETTING: Newly diagnosed pulmonary tuberculosis (PTB) patients starting treatment under the Revised National Tuberculosis Control Programme (RNTCP) in a North Indian city. OBJECTIVE: To quantify impairment in health-related quality of life (HRQoL) of PTB patients at the time of diagnosis and during treatment, and to assess the utility of these assessments as a measure of outcome under programme conditions. DESIGN: HRQoL was assessed using the Hindi version of the 26-item World Health Organization Quality of Life (WHOQOL-BREF) scale at the start and end of the intensive phase and at completion of treatment. Four domain scores-physical, psychological, social relationships and environment-were calculated and compared between groups, based on different patient and disease characteristics. Psychometric evaluation was conducted by assessing acceptability, validity and responsiveness of the questionnaire. RESULTS: A total of 2654 HRQoL assessments were performed among 1034 patients. Domain scores were generally better among men, urban residents, younger patients, patients with higher socio-economic status and those with less severe disease. The WHOQOL-BREF demonstrated good psychometric properties, and domain scores improved with treatment. Residual HRQoL impairment was noted in some patients even at treatment completion. CONCLUSION: HRQoL is impaired in patients with PTB, and improves rapidly and significantly with programme-based treatment. HRQoL assessment can be used as an adjunct outcome measure for patients treated by the RNTCP.
