Individuals with interstitial lung diseases (ILDs) often experience debilitating fatigue, impacting their quality of life. Pulmonary rehabilitation (PR), comprising tailored exercise, education, and behaviour change, aims to improve physical and psychological conditions in ILD patients. Evaluating fatigue and quality of life pre- and post-pulmonary rehabilitation provides insights into its effectiveness in enhancing patient outcomes. Following ethical approval, an exploratory cross-sectional study was conducted at the Department of Respiratory Medicine, Chettinad Hospital and Research Institute. The study enrolled 73 ILD patients admitted between August 2022 and August 2023. Comprehensive pulmonary function assessments and medical histories were obtained from reliable sources and were assessed with questionnaires like the Fatigue Assessment Scale (FAS) for fatigue and St. George Respiratory Questionnaire (SGRQ) for quality of life before and after a 6-month individualized home-based pulmonary rehabilitation program. Seventy-three (73) patients were enrolled in the study. The age group with the highest number of patients was between 50 – 60 years (40%), with a male predominance of 60 % (44). Independent samples of different tools in the research and their mean values were compared using the T-test. This study illustrates the considerable link between the ILD cases for FAS and SGRQ with statistically significant differences in FAS and SGRQ between time durations, at 3 and 6 months duration, indicating improvement in fatigue and quality of life in those patients at a 3 and 6-month duration (p <0.001). The assessment showed a significant decline in fatigue levels (p<0.001) and a marked betterment in the overall quality of life (p<0.0066) among patients after participating in Pulmonary Rehabilitation when compared with FVC severity. These findings underscore the importance of integrating rehabilitation programs into the comprehensive care of these patients to improve their overall health and well-being.
