Access to Lung Cancer Screening Among American Indian and Alaska Native Adults

Background

Lung cancer is the leading cause of cancer mortality among American Indians and Alaska Natives. American Indians and Alaska Native people use commercial tobacco products at much higher rates compared with all other races and ethnicities. Moreover, they show lower adherence to cancer screening guidelines.

Research Question

How do American Indian and Alaska Native adults perceive and use lung cancer screening?

Study Design and Methods

We conducted a study in which we recorded and transcribed data from three focus groups consisting of American Indians and Alaska Native adults. Participants were recruited through convenience sampling at a national health conference. Transcripts were analyzed by inductive coding.

Results

Participants (n = 58) of 28 tribes included tribal Elders, tribal leaders, and non-Native volunteers who worked with tribal communities. Limited community awareness of lung cancer screening, barriers to lung cancer screening at health care facilities, and health information-seeking behaviors emerged as key themes in discussions. Screening knowledge was limited except among people with direct experiences of lung cancer. Cancer risk factors such as multigenerational smoking were considered important priorities to address in communities. Limited educational and diagnostic resources are significant barriers to lung cancer screening uptake in addition to limited discussions with health care providers about their cancer risk.

Interpretation

Limited access to and awareness of lung cancer screening must be addressed. American Indians and Alaska Native adults use several health information sources unique to tribal communities, and these should be leveraged in designing screening programs. Equitable partnerships between clinicians and tribes are essential in improving knowledge and use of lung cancer screening.
