Efficacy of early structured pulmonary rehabilitation program in pulmonary function, exercise capacity, and health-related quality of life for patients with post-tubercular sequelae: A pilot study.
Medical Journal, Armed Forces India 2022 April
Background: Residual structural changes in the lung along with pulmonary impairment remain in a large number of patients of tuberculosis after microbiological cure. The aim of this study was to determine whether 12 weeks of a structured pulmonary rehabilitation program (PRP) administered along with antitubercular treatment improved the baseline measurement of pulmonary function, exercise capacity, and health-related quality of life (HRQOL).
Methods: A pilot study with single blind randomized control design was carried out in a tertiary care chest center. Spirometry, exercise capacity by 6-minute walk distance (6MWD), and HRQOL using St George respiratory questionnaire (SGRQ) score were evaluated in 62 patients, divided into 2 groups: intervention group (IG) (n = 31) and control group (CG) (n = 31) patients at baseline and at end of 12 weeks. IG completed 12 weeks of PRP.
Results: Significant difference in forced expiratory volume in 1st second (FEV1) (2.94 L at baseline vs 3.18 L at end of 12 weeks of PRP, diff 0.239 L, p-0.001), forced vital capacity (FVC) (3.43 L vs 3.75L, p -0.00), 6MWD (440.6 m vs 574.6 m, p = 0.00), and SGRQ score of at baseline (24.5 m vs 11.1m, p = 0.00) was seen in the IG. At end of 12 weeks, there was statistically significant difference in FEV1(L) (p = 0.01, 95% CI -0.317 to -0.046), FVC(L) (p = 0.00, 95% CI -0.359 to -0.139),6MWD(m) (p = 0.00; 95% CI -101.6 to -49.57) between CG and IG. There was no statistically significant difference in SGRQ scores between the 2 groups (p = 0.231).
Conclusion: PRP administered along with treatment is beneficial in reducing residual pulmonary impairment.
