Evaluation of a chest rehabilitation project in Nepal using the St. George's Respiratory Questionnaire and Chronic Obstructive Pulmonary Disease Assessment Test.

The study was open, uncontrolled, and non-randomized, so score changes after one year cannot be compared with a group that did not receive the project. COPD was diagnosed by local clinicians or health workers without pulmonary function tests or bronchodilator reversibility testing, so some participants may have had other diseases. Only 57 of 122 enrolled participants had valid responses at both assessments, and access or travel problems may have left out people who did poorly. The same local organization staff who assessed participants were also involved in delivering and monitoring the project, which could bias ratings. The project included many components, including exercise leaflets, health worker training, volunteer training, community awareness, smoking cessation education, and monitoring, so the contribution of chest rehabilitation alone cannot be separated. No objective lung function, oxygen saturation, walking test, disease severity, physical function, or medication changes were measured.

No conflicts of interest were reported. The project was carried out as a JICA Partnership Program/Official Development Assistance activity and was proposed by the Japan International Medical Technology Foundation.

Do not read the lower SGRQ and CAT scores as proof that chest rehabilitation alone improved quality of life. The study had no control group, COPD diagnosis was not confirmed with lung function tests, and the project combined exercise, leaflets, staff training, community awareness, smoking cessation education, and monitoring, so the effect of any single component cannot be separated.
