Lung Cancer Screening Navigation for Homeless People

The investigators will conduct a pragmatic clinical trial to test the effect of patient navigation on lung cancer screening (LCS) low-dose computed tomography (LDCT) completion among Boston Health Care for the Homeless Program (BHCHP) patients at increased risk for lung cancer. Patient navigation is a strategy for guiding individuals through complex health systems, and the investigators hypothesize that this may be a promising approach for helping homeless-experienced people overcome their unique barriers to obtaining LCS.

The investigators will aim to recruit 300 people to participate in this research study; 100 will be randomly assigned to arm 1 (usual care) and 200 will be randomly assigned to arm 2 (patient navigation). Randomization of participants will be stratified by smoking status, housing status, clinical site, and whether they have previously discussed LCS with their primary care provider (PCP) to ensure balance between study groups on these variables. People assigned to the usual care arm will be referred back to their PCP for further management. People assigned to the patient navigation arm will be given the chance to work with a LCS navigator. The navigator will assist participants and their PCPs with all aspects of the LCS process in addition to offering brief tobacco counseling for current smokers.

The primary aim of the trial is to determine-among homeless-experienced people who are eligible for LCS-the effect of patient navigation on 1) LCS LDCT completion at 6 months post-enrollment and 2) LCS LDCT completion at 6 months with diagnostic follow-up of abnormal results within 1 month of the recommended time frame. Study outcomes will be assessed by examining participant health records.

Following the intervention, qualitative interviews will be conducted with 40 participants and 10 BHCHP PCPs to better understand how the LCS process unfolds in the setting of homelessness, the ways in which the navigator facilitated this process, and opportunities for improving the navigation intervention for future use.

Treatment and study plan

Patient Navigation

Behavioral

The navigator's principal role is to guide participants through the lung cancer screening (LCS) process. The navigator will work within the existing Boston Health Care for the Homeless (BHCHP) clinical structure and collaborate with participants' primary care providers (PCPs) to facilitate LCS low-dose computed tomography (LDCT) referral, completion, and timely follow-up by addressing participants' barriers to LCS completion and enhancing participants' self-efficacy. The navigator's secondary role is to offer brief tobacco counseling for participants who currently smoke.

Primary outcomes

  1. Number (Percentage) of Participants Who Receive Low-dose Computed Tomography (LDCT) for Lung Cancer Screening (LCS) at 6 Months (26 Weeks).

    Time frame: 6 months (26 weeks)

    This outcome will be based on radiology records verifying that a chest computed tomography (CT) was performed for LCS and interpreted according to the lung imaging reporting and data system (Lung-RADS) framework.

Secondary outcomes

  1. Number (Percentage) of Participants Who Receive Low-dose Computed Tomography (LDCT) for Lung Cancer Screening (LCS) at 6 Months (26 Weeks) With Diagnostic Follow-up of Abnormal Results Within 1 Month (4 Weeks) of the Recommended Time Frame.

    Time frame: 6 months (26 weeks) plus guideline-recommended follow-up timeframe plus 1 month (4 weeks)

    Participants must achieve the primary outcome and, if the result is abnormal (lung imaging reporting and data system lung imaging reporting and data system (Lung-RADS) category 3 or 4), also obtain the next recommended follow-up test within 1 month (4 weeks) of the advised timeframe based on the Lung-RADS framework. Radiology records will be obtained for participants who underwent LDCT for LCS to document the findings of the study, determine the Lung-RADS category associated with those findings, and ascertain the recommended diagnostic follow-up plan.

Other outcomes

  1. Time to Completion of Low-dose Computed Tomography (LDCT) for Lung Cancer Screening (LCS)

    Time frame: 6 months (26 weeks)

    Time between date of randomization and date of receipt of low-dose computed tomography (LDCT) for lung cancer screening (LCS) or date of censoring (6 months / 26 weeks)
