Baby Steps III: Testing a Clinician and Patient Intervention to Promote Smoking Cessation Among Pregnant Women

The investigators propose to conduct a combined intervention that pairs SMS smoking cessation messages for patients with individualized training for OB clinicians to improve quit rates among pregnant smoking. The aim is to determine the effect of the intervention versus control on smoking cessation outcomes on patient smoking cessation. The investigators will recruit patients at their first OB visit who report smoking at Duke and Pitt. Patients in both the control and intervention arm will receive smoking cessation support messages throughout their pregnancy. OB clinicians in the intervention arm will receive tailored smoking cessation counseling training. Clinicians in both arms will receive a one-time 5 A lecture. The investigators will analyze smoking cessation outcomes and audio recordings. This is a minimal risk study.

Testing the mHealth App Intervention for Nondaily Smokers "SiS4"

The goal of this project is to test if a new behavioral treatment for people who smoke nondaily and wish to quit works. The new treatment is a smartphone app that engages users in positive psychology exercises and gives them tested tools for quitting smoking. The positive psychology exercises help users maintain their positive emotions while they quit smoking. This app has been developed with and for people who smoke nondaily through several steps of development. The main questions it aims to answer are: * Does the smoking cessation app (SiS4) help people who smoke nondaily quit smoking? * How do people's attitudes towards smoking, their smoking urges, and their mental well-being shift when using the SiS4 app? Researchers will compare the new app to an existing app that was developed for people who smoke daily to see if the new app works better to help people who smoke nondaily quit smoking. Participants will: 1. Use a smartphone app every day for 7 weeks 2. Complete online surveys about their smoking, attitudes about smoking, withdrawal symptoms and smoking urges, app use, and mental well-being at enrollment as well as 2 weeks, 6 weeks, 3 months, 6 months and 12 months after the initially chosen quit date. If the SiS4 app works well, it would be the first evidence-based quit-smoking treatment for people who smoke nondaily.

Adapting and Pilot Testing a Skills-based Smoking Cessation Intervention to Address Developmental and Health-related Stress Among Adults Who Smoke

Smoking remains the leading preventable cause of death in the United States, and there are persistent and significant disparities in tobacco use among transgender and gender diverse (TGD) individuals. Stigma, discrimination, gender dysphoria, and other gender minority stressors likely contribute to these disparities, and the increased burden of gender minority stress may also be driving higher prevalence rates of anxiety and depression, both of which are more common among TGD individuals and among those who smoke relative to comparison samples. This study will (1) explore the ways in which gender minority stressors and associated anxiety and depression compromise smoking cessation among TGD individuals, identifying elements in an existing smoking cessation intervention that need to be adjusted to meet their unique needs; (2) adapt an existing smoking cessation intervention for TGD individuals; and (3) evaluate the feasibility and acceptability of the adapted intervention in a pilot randomized controlled trial.

Effectiveness of Transcranial Magnetic Stimulation (TMS) in Smoking Cessation, Combining Withdrawal Stimulation Followed by Maintenance Stimulation to Prevent Relapse.

Tobacco control is a Public Health priority. Tobacco is directly responsible for 75,000 deaths per year in France. Without help, less than 5% of smokers are still abstinent within 12 months of quitting. The use of nicotine substitutes only increases the chances of success in smoking cessation by 2 to 3%. Brain imaging research shows that the dorsolateral prefrontal cortex (DLPFC) is involved in tobacco addiction. Disorders induced in the CPFDL cause an irrepressible desire to smoke (craving) and explain a large part of the relapse at the time of smoking cessation. Transcranial magnetic stimulation (TMS) could be promising in smoking cessation. This technique allows direct stimulation of the DLPFC via a magnetic coil, so as to reduce the cortical activity of the DLPFC, and thus reduce tobacco craving. A first randomized controlled study was conducted at the Dijon University Hospital in Dijon in smokers who were heavily addicted and who had failed with the usual withdrawal strategies. In this study, it was found that the combination of nicotine substitutes (to reduce the physical symptoms of withdrawal) with 10 sessions of TCS (to reduce craving) made it possible to maintain abstinence from tobacco during the first 2 weeks of withdrawal (% abstinence = 88.8% active TCS group vs. 50% placebo TCS group; p=0.027). However, in this study, the therapeutic effect of the nicotine-TCS combination was not prolonged once the stimuli stopped. At 6 and 12 weeks from the start of withdrawal, abstinence rates in the active SMT and placebo SMT groups were no longer significantly different. It is therefore proposed to renew the protocol by adding maintenance brain stimulation to the initial protocol. Used in the treatment of depression, the maintenance brain stimuli could increase the chances of smoking cessation.

Impact of Lung Cancer Screening With Chest Scans Combined With Coaching on Smoking Cessation in Heavy Smokers

Lung cancer is common and serious, but when detected early, the chances of recovery are significantly better. Tobacco use is the leading cause. To help people break free from smoking, the Fribourg Cantonal Hospital (HFR), the Center for Tobacco Prevention (CIPRET), and the Fribourg Cancer League are joining forces in the STOP-LungCancer study (Smoking Termination Outcomes with Pulmonary Low Dose Computed Tomography for Lung Cancer Screening). What is the goal of this study? The investigators want to determine whether seeing and understanding images of the participants' own lungs helps participants quit smoking for good. Smoking cessation will be verified at 6 months using a breath test (measuring carbon monoxide), followed by a 2-year follow-up. How does participation work? The study is open to 116 residents of the canton of Fribourg aged 50 to 79 who are heavy smokers and motivated to quit. The program includes: 1. Personalized support: 4 smoking cessation coaching sessions organized by CIPRET. 2. Lung computed tomography (CT) scans: 3 exams spaced one year apart. This scan involves no needles or injections. The radiation dose is very low, about 0.6 millisieverts (mSv) per scan, and the associated risk is considered very low. 3. A review of the images with a doctor: During dedicated consultations, a thoracic radiologist reviews the participant's own computed tomography (CT) scans with the participant to explain the condition of the lungs and heart. What are the benefits? Participants receive both tailored support to quit smoking and close monitoring to detect any potential issues at a very early stage.

CONNECTing to LungCare

This study evaluates a smoking cessation intervention (CONNECTing to LungCare) for improving shared decision-making conversations about smoking cessation and lung cancer screening between patients and providers. Shared decision making is a patient care model in which providers offer information regarding risks and benefits, patients express their values and preferences, and then healthcare decisions are jointly discussed between the patient and provider. Patient education, aided by decision support tools, can increase patients' knowledge, decrease their decisional conflict, promote decision making, and improve the patients' perception of risk. CONNECTing to LungCare is an interactive education intervention that addresses lung cancer screening and smoking cessation and provides participants with a tailored summary that may make them more likely to have shared decision-making discussions with their providers about smoking cessation and lung cancer screening.

Health Systems Reach Interventions Project

This project seeks to identify ways to enhance the reach of evidence-based smoking cessation treatments among adult primary care patients who smoke daily and are not ready to start treatment at study enrollment. The 2x2x2x2 factorial experiment will evaluate the extent to which 4 intervention components promote the use of evidence-based treatments to help smokers not initially ready to quit to cease smoking over 2 years. The intervention components tested include: modest financial incentives for completing an initial counseling session in a smoking cessation treatment (vs. none); automated semi-annual outreach materials sent via patients' preferred communication modality using data in the electronic health record to tailor and personalize invitations to use available treatments to quit smoking (vs. untailored letters); direct, proactive telephone outreach from a tobacco care manager who will promote treatment use and deliver motivational intervention twice per year (vs. none); and access to 3 no-cost telephone smoking cessation counseling calls with combination nicotine replacement therapy (C-NRT) or varenicline (vs. state tobacco quitline and primary care provider referral). Proactive treatment offers will be made up to 22 months after enrollment. Smoking status and use of any smoking cessation treatments will be assessed every 6 months through 2 years of study enrollment. Data from 1664 adult primary care patients meeting inclusion/exclusion criteria will be analyzed to see whether the intervention components have an effect on the use of treatment (primary outcome) and smoking status after 2 years of treatment access (secondary outcome). The project will evaluate the manipulated intervention components first in terms of treatment initiation (defined as rates of completing at least 1 smoking cessation counseling session prior to a target stop-smoking date), and then in terms of end-of-study (2 year post-enrollment) abstinence rates (secondary outcome), and cost-effectiveness in promoting reach (tertiary outcome). This experiment will help to identify health system reach interventions that effectively enhance utilization of stop smoking treatments in an effort to help more smokers quit and to prevent tobacco-induced cancer morbidity and mortality.

Smoking Cessation Pharmacotherapy-Nurse Practitioner Led Tobacco Treatment Team Study

Tobacco use remains the leading cause of death in the United States and contributes to more than 7 million hospitalizations annually. Being admitted to the hospital offers the perfect opportunity to support smoking cessation. Patients are motivated to quit because of their current illness and societal guidelines recommend clinicians should counsel patients and prescribe smoking cessation pharmacotherapy (SCP) to virtually all smokers. However, only 22% of patients are prescribed SCP while hospitalized, and only 1% are prescribed medications compatible with current guidelines. This failure is part of the reason 70-80% of hospitalized smokers eventually relapse. The relapse typically occurs within a few days of hospital discharge - well before outpatient follow-up can occur. The investigators aim to improve smoking cessation treatment and guideline adherence by utilizing the opportunity that hospitalization provides. The investigators have created a tobacco treatment team (T3) to overcome physicians' and patients' low use of current guideline smoking cessation medications. The team members are trained in tobacco treatment and will be led by a nurse practitioner (NPT3). The team will work together and 1) prescribe individually tailored and guideline-concordant SCP; 2) counsel and motivate patients to use SCP properly; and 3) manage a mobile phone-based text-messaging system to keep patients motivated and adherent to SCP. Our preliminary data suggest that such an approach is workable and acceptable to patients, physicians, and hospital administrators. The investigators will recruit 424 patients in the hospital who smoke with cardiopulmonary disease. These patients will be randomized to receive either usual care or personalized care with the NPT3 team. The investigators will compare rates of guideline-concordant SCP use at 1 week and exhaled carbon monoxide (eCO) verified smoking cessation at 6 months between patients randomized to the NPT3 team vs. usual care. The investigators will also measure the project's economic value from a hospital and payer perspective. Understanding the economic value will better inform hospital and insurance policies and sustainability. Finally, acceptability, generalizability, and sustainability measures will be assessed through qualitative interviews with patients, providers, and hospital leadership.

App for Pregnancy Smoking Cessation With Peer Support

The objectives of this project are to develop, implement, and test the feasibility and effectiveness of an artificial intelligence adaptive mobile pregnancy tobacco cessation app-based intervention using deep tailoring and a self-nominated support person, and to build mHealth research capacity in Romania. The central hypothesis is that the intervention will show evidence of feasibility and effectiveness in increasing positive support, pregnancy cessation, and postnatal abstinence. The intervention is grounded in Self-Determination Theory (SDT) and Motivational Interviewing (MI), a counselling style that is effective in assisting people to quit smoking. The app will be novel in its use of the unique functionality of smartphones, use of reinforcement learning (RL) and deep tailoring to continuously adapt the intervention, the emphasis on increasing positive support, and the use of the app by both smoker and support person. The long-term goal of the research program is to use mHealth for smoking cessation leveraging the unique functionality of smartphones and to continue building mHealth research capacity and developing research networks in Central and Eastern Europe (CEE) and other LMICs. Aim 1 (R21 phase). Develop and test the feasibility and acceptability of the SFT2.0 app-based mobile smoking cessation intervention with a support person during pregnancy and postpartum in Romania. Through a user-centered and iterative design the investigators will enhance the SFT1.0 app, deepen the tailoring, incorporate RL, expand the app for use by any support person, and test the intervention including the app and MI video counseling in a series of usability studies and a 12-week open trial (n=20). Aim 2 (R33 phase). Test the SFT2.0 app-based smoking cessation intervention in a hybrid effectiveness and implementation randomized controlled trial. The investigators will randomize 375 pregnant smokers and their support persons to i) a fixed arm, including the SFT2.0 app for both, and fixed pre- and postnatal MI counseling; ii) an RL-adaptive arm, with the app continuously optimizing as-needed MI counseling; or iii) control group. Aim 3 (R21 and R33 phases). Develop mHealth research capacity by enhancing individual and institutional research capabilities in Romania and expanding the existing international research network.
