Participant Flow

Trial recruitment occurred between 2020-2022. The trial was conducted at Boston Health Care for the Homeless Program (BHCHP), a federally-qualified healthcare for the homeless program that serves nearly 10,000 patients each year across more than 30 service sites in greater Boston (www.bhchp.org). Individuals were recruited through a combination of in-person and phone-based outreach as well as referrals from BHCHP primary care providers.

In total, 261 participants enrolled but one participant chose to withdraw before completing the baseline survey and therefore could not be randomized.

Participant milestones

Participant milestones
Measure
Usual Care Without Patient Navigation
Participants assigned to this arm will be given basic educational materials on general lung health and referred back to their primary care provider (PCP) for management as per usual practice.
Usual Care With Patient Navigation
Participants assigned to this arm will be informed about lung cancer screening (LCS), provided educational materials on LCS and patient navigation, and offered access to an LCS navigator who will partner with participants and primary care providers (PCPs) to facilitate low-dose computed tomography (LDCT) completion and follow-up. Patient Navigation: 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.

SECONDARY outcome

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

Population: Participants who completed LDCT for LCS with Lung-RADS scores ≥3 meriting earlier than annual follow-up (typically 6 months for Lung-RADS 3, 3 months for Lung-RADS 4A, and immediate for Lung-RADS 4B/X). In the usual care without patient navigation arm, 1 participant received a Lung-RADS score of 4A. In the usual care with patient navigation arm, 6 participants received a Lung-RADS score of 3, 2 participants received a score of 4A, and 1 participant received a score of 4B.

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.
