Community Program for Chronic Respiratory Diseases

(INTERLUNG Trial)

This trial aims to determine if a community health volunteer-led program can improve lung health for people in Bhaktapur, Nepal, who are at risk of chronic respiratory diseases like asthma or COPD. The program, a multi-component respiratory health intervention, focuses on reducing tobacco smoke, air pollution, and respiratory infections while promoting physical activity. Participants are divided into two groups: one receives regular health advice and support, while the other continues with their normal care. Residents of Bhaktapur who often experience coughing, wheezing, or have had asthma or tuberculosis might be a good fit for this study. As a Phase 4 trial, this research involves an FDA-approved treatment and aims to understand how it can benefit more patients.

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the study team or your doctor.

Research has shown that programs led by community health workers are generally safe and well-tolerated. Studies have found that these programs help people manage conditions like asthma and COPD without significant side effects. For example, community health workers have successfully improved asthma control and quality of life without major problems. They teach people how to reduce triggers at home, and no serious adverse events have been reported.

Researchers are excited about this community health worker-delivered intervention for chronic respiratory diseases because it takes a comprehensive, hands-on approach to improving respiratory health. Unlike standard treatments that may focus on medication and occasional doctor visits, this intervention includes home visits by trained community health workers who provide guidance and tools like HEPA air purifiers and vacuum cleaners to reduce environmental risk factors. It also emphasizes preventive measures such as tobacco cessation, mask usage during high pollution or illness seasons, and vaccinations against flu and pneumonia. This holistic approach aims not just to treat symptoms but to enhance overall respiratory health by addressing environmental and behavioral factors.

Research shows that programs led by community health workers can improve lung health. In this trial, participants in the intervention arm will receive a multi-component intervention delivered by community health workers. This intervention aims to reduce environmental and infectious respiratory risk factors and promote healthy behaviors. Studies have found that such programs enhance asthma management by improving communication between families and healthcare providers. Participants often experience significant improvements in asthma control, with benefits continuing even after the program ends. Evidence also suggests that community health workers can help reduce diseases like chronic obstructive pulmonary disease (COPD). This approach effectively manages breathing problems by encouraging healthier habits and reducing risk factors.¹³⁶⁷⁸
