Brief summary
Individual-level, unblinded randomized controlled trial of an 8-week (short arm) or 24-week (extended arm) pulmonary rehabilitation program, relative to standard of care, to prevent post-tuberculosis respiratory morbidity. Randomization will occur in a 1:1:1 ratio at the initiation of treatment.
Detailed description
8 weeks (short arm) or 24 weeks (extended arm) of a pulmonary rehabilitation (PR) program, administered during TB treatment, comprising of exercise training, counselling and education, and airway clearance techniques. Objectives: 1. To compare the effectiveness of two home-based PR programs, administered during TB treatment, for preventing post-TB respiratory morbidity. 2. To describe the intersection between clinic-level service organization, fidelity of intervention delivery, and change in client behavior for the two PR programs. 3. To compare the costs, cost-effectiveness, and budget impact of the two different PR strategies implemented as a routine program.
Interventions
8 weeks (short arm) of a pulmonary rehabilitation (PR) program, administered during TB treatment, comprising of exercise training, counselling and education, and airway clearance techniques.
24 weeks (extended arm) of a pulmonary rehabilitation (PR) program, administered during TB treatment, comprising of exercise training, counselling and education, and airway clearance techniques.
