Abstract
ABSTRACT Introduction Access to interstitial lung disease programs may not be available in rural settings. Home-based pulmonary rehabilitation (PR) programs have been proposed as an alternative to hospital-based programs. Method Forty participants with ILD underwent a structured unsupervised home-based pulmonary rehabilitation program from September 2020 to September 2022. Quality of life was assessed using St. George Respiratory Questionnaire (SGRQ) and functional capacity using 6-minute walk test (6MWT). The outcome measures were assessed at baseline and 4 weeks post-unsupervised home-based PR program. Result We recruited 40 participants with ILD. There was statistically significant improvement in the 6-minute walk distance (353.8 m and 368 m, effect size – 0.5, p ≤ .001) and quality of life using SGRQ total score (38.6 and 42.35, effect size – 2.5, p ≤ .001) between before and after receiving home-based PR among all 40 participants with ILD. Conclusion Four weeks of home-based PR program, using minimal resources, deliver short-term improvements in functional exercise capacity and quality of life among ILD participants. Our home-based PR program resulted in a quarter percentage improvement in functional capacity, and we believe that if consistency is maintained, it will result in similar changes corresponding to the already established Minimal Clinically Important Difference (MCID) of 35 m.
