Community Health Worker Intervention for Lung Cancer Screening

(CHATS Trial)

The trial aims to find better ways to encourage lung cancer screening. It tests two approaches: one using community health workers and the other using trained lay navigators. Both groups assist with decision-making, tobacco treatment, and overcoming barriers to care. This trial may suit individuals aged 50 to 80 with a history of smoking who receive primary care at specific community health centers. As an unphased trial, it provides a unique opportunity to contribute to innovative strategies that could improve lung cancer screening rates.

Research has shown that programs using community health workers and patient guides are generally well-accepted. Previous studies on similar programs, such as those with lay navigators, demonstrated their safety. These programs assist patients by guiding them through their healthcare journey and facilitating access to care. No major reports of negative effects have emerged from using community health workers or lay navigators. Participants typically find these programs helpful and unobtrusive, with no serious side effects reported. This suggests that the programs in the current trial are likely safe and well-received.¹²³⁴⁵

Researchers are excited about this trial because it explores innovative methods to improve lung cancer screening uptake. Unlike traditional methods, which often rely solely on educational materials, this trial tests two interventions: one delivered by community health workers and another by trained lay navigators. Both interventions offer a comprehensive approach, combining patient outreach, shared decision-making, tobacco treatment counseling, and assistance with overcoming logistical barriers. This personalized and supportive method aims to make lung cancer screening more accessible and engaging, potentially leading to higher participation rates and earlier detection of lung cancer.

Research shows that community health workers (CHWs) can effectively boost lung cancer screening rates. In this trial, one group of participants will receive a four-part intervention delivered by CHWs, including patient outreach, shared decision-making, tobacco treatment counseling, and navigation of logistical barriers. Studies have found that CHW programs help participants smoke fewer cigarettes, with 29% quitting completely after a year. Another study discovered that guiding patients through the healthcare system significantly increases lung cancer screening among smokers.
