About this study
Official title: Reducing Tobacco Use Disparities Among Adults In Safety Net Community Health Centers
Most smokers, especially those who are poor, do not receive smoking cessation treatment during their healthcare visits. This study is evaluating a novel population health management intervention for low-income smokers. Automated via an EHR system, which is bidirectionally linked with the Illinois Tobacco Quitline, the intervention comprises a mailed letter and text messaging designed to motivate low-income patients, most of whom are not ready to quit, to accept and use proactive quitline treatment. Increased access to free effective treatment via the integration of healthcare systems and state quitline services may be especially significant in its impact on low-income smokers who are underserved and who carry a much greater burden of tobacco-related disease.
Read the detailed description
An estimated 26 million smokers still receive no treatment for their smoking during their primary care visits. Given the persistent clinical system, provider, and patient barriers to addressing smoking in primary care, especially for poor populations, an electronic health record (EHR)-automated population health management approach that directly links the healthcare system with public health services to engage all smokers may increase access to effective treatment. Increased access is especially significant for low-income smokers who are underserved and who carry a disproportionate burden of tobacco-related disease. While 90% of smokers are not ready to quit, many are interested in cutting down, and smoking reduction increases the likelihood of future quit attempts and smoking cessation. Based on self-determination theory, population outreach targeted to low-income smokers that offers them the choice to either quit or cut down as a first step towards cessation may increase their engagement in and utilization of smoking cessation treatment and likelihood of achieving abstinence. This 2-group randomized controlled trial will evaluate the effectiveness of a population health management intervention for smoking cessation in low-income smokers. Participants will be 530 diverse, low-income smokers of a large Federally Qualified Health Center (FQHC) in Chicago identified using its EHR system. Automated via the EHR system, participants will be mailed a letter on behalf of their providers that encourages smoking cessation or smoking reduction as a first step to quitting (Choose to Change; N=265). The letter will be paired with 5 text messages 2-3 days apart that are designed to reinforce the central messaging of the letter ("Choose to change and make your own goal"). All components of the Choose to Change intervention will be offered in English and Spanish. Two weeks after letter mailing and automated electronic referral, participants will receive a call from the Illinois Tobacco Quitline and offered free behavioral counseling and free nicotine replacement therapy (NRT; patch, gum, or lozenge) for smoking cessation or reduction. Treatment will continue as either accepted or initiated by participants for 28 weeks. Treatment outcomes will be transmitted directly from the Quitline server to the EHR system. Choose to Change will be compared with Enhanced Usual Care (N=265), in which an electronic referral for proactive Quitline treatment is made during a clinic visit. The primary study outcomes will be treatment engagement (initial counseling call completed) at 6 weeks, utilization (one or more additional counseling calls completed) at 14 weeks, and smoking cessation (bioverified 7-day point-prevalence abstinence) at 28 weeks. An exploratory aim is to examine moderators of intervention effects. An EHR-automated population health management intervention targeted to low-income smokers could reduce critical disparities in treatment access, utilization, and cessation. If determined to be effective, the Choose to Change intervention could be readily disseminated to 11 other FQHCs in Chicago, comprising 85 clinical sites that care for almost 500,000 low-income patients.

What participants receive

Choose to ChangeBehavioural
Population-based letter outreach automated via the electronic health record system and text messaging targeted to low-income smokers. Paired with automated electronic referral for proactive quitline treatment (behavioral counseling plus nicotine replacement therapy).
Enhanced usual careBehavioural
Enhanced usual care based on Ask, Advise and Refer in which an electronic referral for proactive quitline treatment (behavioral counseling plus nicotine replacement therapy) is made during a clinic visit.
| Study group | Role | What they receive |
|---|---|---|
| Population health management | Experimental | Population health management for smoking cessation in low-income smokers: the Choose to Change intervention Receives: Behavioral: Choose to Change |
| Enhanced usual care | Active comparator | Usual clinic-based care enhanced by an EHR system that can deliver an electronic referral for quitline treatment Receives: Behavioral: Enhanced usual care |
What is being measured
The primary outcome is the main question the study is designed to answer.
Quitline Treatment Engagement
The number of participants who accepted the quitline call and accepted treatment as defined by enrolling in treatment and completing the first counseling session. Participants who returned a quitline call, enrolled in treatment, and completed the first counseling session were also counted as having engaged in treatment.
Measured: Week 6
Quitline Treatment Utilization
The number of participants who completed one or more additional quitline counseling calls.
Measured: Week 14
Smoking Cessation at Week 28 (32 Weeks After Enrollment)
Self-reported seven-day point-prevalence abstinence at week 28. Number of participants who reporting smoking cessation at week 28. Participants were classified as abstinent if they reported not smoking (not even a puff of a cigarette) for at least 7 days prior to the assessment.
Measured: Week 28
Secondary outcomes (1)
Smoking Cessation at Week 14 (18 Weeks After Enrollment)
Self-reported seven-day point-prevalence abstinence at week 14. Participants were classified as abstinent if they reported not smoking (not even a puff of a cigarette) for at least 7 days prior to the assessment.
Measured: Week 14

Questions about this trial
What is this clinical trial studying?
A study testing Choose to Change in people with Cigarette Smoking and Nicotine Dependence, run by Northwestern University at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 21 Jan 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 12 Jan 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Quitline Treatment Engagement (time frame: Week 6). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03077737, which also lists 12 linked publications.
Does a listing mean the treatment is approved or proven to work?
