About this study

Lung cancer screening (LCS) can reduce lung cancer-related mortality, but screening uptake remains low among eligible individuals. The goal of this study is to partner with community stakeholders to develop and pilot test a multi-component navigator-delivered intervention targeting key barriers to lung cancer screening and tobacco treatment utilization. Participants are randomized to enhanced usual care, a community health worker (CHW)-delivered intervention, or the same intervention delivered by a trained lay navigator. The intervention includes patient outreach, patient-centered shared decision-making, tobacco treatment counseling, and assistance navigating logistical barriers to care. The proposed activities will lay the groundwork for a subsequent fully powered randomized clinical trial evaluating CHW- and lay navigator-delivered approaches to facilitate access to lung cancer screening and tobacco treatment.

Read the detailed description

Lung cancer is a leading cause of cancer death, and lung cancer screening (LCS) with low-dose computed tomography can reduce lung cancer-related mortality among eligible individuals. However, uptake of LCS remains low, particularly among populations that face barriers to accessing preventive care.

Community health worker (CHW) interventions have been effective at promoting screening and reducing barriers to care in other cancer settings. This study was designed to develop and pilot test a multi-component intervention intended to improve LCS uptake and tobacco treatment utilization. The intervention includes four components: 1) patient outreach, 2) patient-centered shared decision-making about lung cancer screening, 3) tobacco treatment counseling for participants who currently smoke, and 4) navigation of logistical barriers to care.

The intervention was developed in partnership with a community advisory board composed of community stakeholders and individuals with lived experience, using principles from the Transcreation Framework for Community-Engaged Behavioral Interventions.

The pilot randomized controlled trial is being conducted within Baystate Health community health centers. Participants are randomized to one of three study arms: 1) enhanced usual care, which includes mailed lung cancer screening educational materials and usual screening care through the participant's primary care provider; 2) the multi-component intervention delivered by a community health worker; or 3) the same multi-component intervention delivered by a trained lay navigator, such as a research assistant or pre-medical student.

The study will evaluate the feasibility of implementing the intervention using different navigator models. Primary pilot outcomes include participant recruitment, measure completion, retention, intervention fidelity, and acceptability. Secondary outcomes include lung cancer screening and tobacco treatment utilization. The study will also explore potential mechanisms through which the intervention may influence screening, including knowledge about lung cancer screening and assistance overcoming logistical barriers to care.

Findings from this pilot study will inform the design of a future, fully powered randomized controlled trial evaluating approaches to improving access to lung cancer screening and tobacco treatment.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Feasibility: Number of participants at each stage of the recruitment and retention cascade

    Counts abstracted from the study screening and enrollment log at each of the following stages: approached, screened eligible, consented, randomized, completed baseline data collection, and completed post-intervention follow-up assessment.

    Measured: once a month until study trial ends, an average one year

  2. Feasibility: Percentage of participants at each stage of the recruitment and retention cascade

    Percentages calculated from the study screening and enrollment log. Eligibility rate = number screened eligible divided by number approached. Consent rate = number consented divided by number screened eligible. Randomization rate = number randomized divided by number consented. Baseline completion rate = number completing baseline data collection divided by number randomized. Retention rate = number completing post-intervention follow-up divided by number randomized.

    Measured: once a month until study trial ends, an average one year

  3. Fidelity: Duration in minutes of shared decision making (SDM) counseling per encounter

    Time in minutes spent on SDM, recorded by community health workers (CHWs) and lay navigators in the encounter/call tracking log.

    Measured: once a month until study trial ends, an average of 1 year

  4. Fidelity: Duration in minutes of smoking cessation counseling per encounter

    Time in minutes spent on smoking cessation counseling,recorded by community health workers (CHWs) and lay navigators in the encounter/call tracking log.

    Measured: once a month until study trial ends, an average of 1 year

  5. Fidelity - SDM quality using OPTION Scale Observer OPTION Scale

    Mean total score on the OPTION Scale Observer OPTION Scale scored from audio-recorded SDM encounters; 12 items rated 0 ("not observed") to 4 ("exhibited at a very high standard"), total score 0-48, with higher scores indicating greater SDM competence.

    Measured: once a month until study trial ends, an average of 1 year

  6. Fidelity - Completion of SDM required elements

    Mean count of CMS SDM Elements completed during each encounter: reduced lung cancer mortality, false positive, overdiagnosis, radiation exposure, annual screening, smoking cessation, follow-up testing, and diagnostic procedures.

    Measured: once a month until study trial ends, an average of 1 year

  7. Fidelity: Percentage of participants with documented use of the SDM decision aid

    Proportion of participants for whom the SDM decision aid was used, documented in the CHW and lay navigator encounter log.

    Measured: Monthly through study completion, an average of 1 year

  8. Fidelity: Percentage of participants referred to tobacco treatment services, by type

    Proportion referred to any tobacco treatment service by type (telephone quitline, in-person counseling,), from EHR referral orders and the CHW and lay navigator encounter log.

    Measured: Monthly through study completion, an average of 1 year

  9. Acceptability of the CHW and lay navigator intervention to participants

    Qualitative themes regarding overall experience with the CHW and lay navigator intervention and barriers to lung cancer screening, identified through thematic analyses of semi-structured interviews using a study-specific interview guide. Participants (N=15), ~40-45 minutes, conducted in private at 3-month follow-up;

    Measured: 3 months post-enrollment (participants) and through study completion, an average of 1 year (navigators)

  10. Acceptability of the intervention to CHWs and Lay navigators

    Qualitative themes regarding overall experience with the Naviagtor intervention and barriers to lung cancer screening, identified through thematic analysis of Navigator encounter logs and semi-structured interviews using a study-specific interview guide. Navigators (N=3), one 45-minute interview each after final intervention delivery.

    Measured: 3 months post-enrollment (participants) and through study completion, an average of 1 year (navigators)

Secondary outcomes (5)

Individual data sharing
No: Sharing qualitative data such as transcriptions from interviews can potentially reveal sensitive information and identify individual participants. The higher level of redaction needed to remove potentially-identifying and sensitive information would substantially reduce the utility of transcripts in future analyses.To ensure this group's participation and honest responses, we will not share transcripts or coding summaries from participant or community health worker interviews. The goal of this pilot trial is to provide preliminary information to support a future fully powered randomized trial to address disparities in lung cancer in Black and Hispanic communities. Given that these community members have historically been subject to unethical research practices, we will limit the potential for further distrust by not sharing de-identified information outside of the study team or its collaborators.
