Abstract Background Chronic obstructive pulmonary disease (COPD) is one of the leading causes of death worldwide and the commonest of non-communicable diseases (NCDs) in Nepal. Risk factors like indoor and outdoor air pollution, a high prevalence of smoking, and the lack of awareness of COPD make it a serious public health concern. However, no attempt has been made in Nepal to estimate its burden and address the disease at the community level. Method This study aims to evaluate the effect of a community-based health educational intervention administered by Female Community Health Volunteers (FCHVs) on the prevention and management of COPD. An open-label, two-group, community-based, cluster-randomized controlled trial will be implemented in the semi-urban area of Pokhara Metropolitan city (former Lekhnath Municipality) located in the Kaski district of Nepal. The estimated sample size of the intervention will be 1143. The unit of randomization is the ward (administrative unit) of the study area. The follow-up survey will be conducted immediately after 12 months of FCHVs-led interventions. The difference in the rate of decline of forced expiratory volume in 1 s (FEV1) and FEV1/FVC (forced vital capacity) ratio are the primary outcomes and the change in the proportion of modifiable risk factors of COPD, health-related quality of life scores, and change in knowledge of COPD will be secondary outcomes. Discussion This study will estimate the burden of COPD, the magnitude of risk factors and generate evidence to mobilize community health workers for COPD prevention and management at the community level in Nepal.
