Chronic obstructive pulmonary disease (COPD) is characterized by airflow limitation that is not fully reversible. The study "Quality of life among people living with Chronic Obstructive Pulmonary Disease- visiting spirometry center of Tribhuvan University Teaching Hospital, Kathmandu Nepal" aims to assess the quality of life (QOL) of COPD patients and the factors affecting it.

A cross sectional study will be performed among the patients visiting Spirometry center of Tribhuvan University Teaching Hospital, Kathmandu Nepal using Convenience Sampling. Ethical approval will be obtained from Institutional Review Board (IRB) of TUTH and written/verbal consent for data collection will be obtained from Teaching hospital authority as well as the respondents. CAT questionnaire will be used to assess quality of life and the Medical Research Council questionnaire will be used to assess the severity of dyspnea. Data management and analysis will be conducted through Statistical Package for Social Sciences (SPSS) version 26.0.

Inclusion Criteria:

• Age ≥ 20 years
• Referred to the spirometry center of Tribhuvan University Teaching Hospital
• Confirmed diagnosis of COPD based on GOLD criteria: post-bronchodilator FEV1/FVC < 0.7

Exclusion Criteria:

• Unable to perform acceptable spirometry maneuvers
• Presence of significant respiratory diseases that can confound COPD assessment (e.g., asthma, bronchiectasis, active tuberculosis)

The study enrolled participants aged 20 years or older who were referred to the spirometry center of Tribhuvan University Teaching Hospital. The primary inclusion criterion was a confirmed diagnosis of COPD based on the Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria, defined as a postbronchodilator ratio of forced expiratory volume in one second to forced vital capacity (FEV1/FVC) < 0.70.

Since this is an observational study focused on evaluating the quality of life of COPD patients, Individual Participant Data (IPD) will not be shared as part of the study's results. However, the aggregated findings, such as overall satisfaction scores and analysis of demographic factors influencing consent understanding, will be presented in the final study report.
