About this study

Official title: Incentivized Smoking Cessation for Tobacco Treatment-Resistant Diabetics

This pilot study aims to test the feasibility of providing incentives to patients with T2D contingent on remote biochemical verification using a smartphone carbon monoxide (CO) monitor. The investigators will use an ecological momentary assessment (EMA) smartphone application and CO sensor to monitor urges to smoke, stressors, smoking behaviors, and to validate continuous abstinence throughout the intervention. Two different contingency management structures will be explored to investigate the length of time incentives need to be offered.

Read the detailed description

Individuals with type 2 diabetes (T2D) are at an increased risk of many cancers, though the causal link is not well understood. Continuing to smoke after a T2D diagnosis is also associated with accelerated progression of microvascular and macrovascular complications and an increased risk of death. Smoking cessation is recommended as a standard treatment for diabetes. However, both patients and providers are faced with other challenging lifestyle changes and disease management processes, which lead to greater difficulty in quitting.

Contingency management, or a method of providing financial incentives contingent upon positive behaviors, has shown promise for improving adherence to medication among diabetics and for improving smoking cessation in other populations. This approach could offer an innovative and scalable means of increasing abstinence in this group, ultimately reducing their risk of cancer. This is a multicenter pilot randomized controlled trial that will recruit participants in Oklahoma and in Strathclyde, Scotland.

This pilot study aims to test the feasibility of providing incentives to patients with T2D contingent on remote biochemical verification using a smartphone carbon monoxide (CO) monitor. The investigators will use an ecological momentary assessment (EMA) smartphone application and CO sensor to monitor urges to smoke, stressors, smoking behaviors, and to validate continuous abstinence throughout the intervention. Two different contingency management structures will be explored to investigate the length of time incentives need to be offered. Qualitative semi-structured interviews will be used to explore the patient and provider acceptability of an incentive-based cessation program, any unintended consequences and possible differences between UK and US health settings.

The results of this research will inform the feasibility of carrying out a randomized controlled trial of this intervention. The ultimate aim is to develop an effective intervention that could be scaled to the T2D population at large, which reduces cancer risk and improves disease outcomes among a high-risk group.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Financial incentivesBehavioural

    Treatment arm participants will receive financial incentives ($20 per week) contingent on biochemically verified smoking abstinence submitted once daily for the time period allocated.

Secondary outcomes (2)
  1. Quit outcomes

    Proportion of participants who quit smoking

    Measured: 12 weeks

  2. Cigarettes per day

    Reduction in cigarettes smoked per day

    Measured: 12 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Financial incentives in people with Smoking Cessation and Diabetes Mellitus, Type 2, run by University of Oklahoma at 2 sites in 2 countries.

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 2 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 6 Dec 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States, United Kingdom. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Proportion of CO readings completed (time frame: 12 weeks). 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 NCT03527667, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Dec 2019.
