About this study

Official title: Contingency Management for Controlling Secondhand Smoke Exposures Among Asthmatic Children

Secondhand smoke exposure (SHSe) is one of the most common and potentially modifiable environmental triggers for asthma. Financial incentivization may serve as an effective modality to reduce SHSe among pediatric asthmatics with potential down-stream benefits on improved asthma control and subsequent reduced healthcare utilization. This study plans on testing the feasibility and effectiveness of financial incentives to decrease SHSe, derived from primary caregivers and a member of their social network, of children with persistent asthma.

Read the detailed description

The impact of continued cigarette usage is profoundly felt not only upon the primary smoker, but also among children where SHSe is linked with asthma exacerbations. Children with caregivers who are active smokers are more likely to utilize acute healthcare resources and miss more days of school due to asthma symptoms. Issues of pediatric smoke exposure are notably higher among low-income populations. This particular group has a greater amount of financial strain that increases their desire to cease smoking but is among the least successful at accomplishing this task. Aggressive marketing campaigns by cigarette companies have specifically targeted the urban poor but similar techniques by public health officials, though on a much diminished scale, have yet to completely counter the hold that this addictive product has on members of lower socioeconomic status. One approach that has demonstrated efficacy in reducing smoking in resistant populations emphasizes financial incentives. Incentives may provide a substitute for the gratification derived from nicotine if they are properly structured. This proposal applies a contingency management schema among caregivers of pediatric asthmatics and a member of their caregiver's social network - both of whom are likely major contributors to the child's total secondhand smoke exposure. A pilot two-arm randomized-control trial will be employed over a 6-month time interval.The study population will consist of the primary caregiver and a selected member of their social network, both of who are known active smokers, and contemplating smoking cessation; both individuals spend time (either indoors or outdoors) with the asthmatic child. We will recruit 50 caregiver-child-social network triads among a population of children diagnosed with uncontrolled, persistent asthma and routinely exposed to high levels of SHSe. Caregivers and members of their social network who are both active smokers will be randomized to receive standard smoking cessation strategies (n=25 triads) with or without financial incentives (n=25 triads). SHSe will be measured directly using salivary cotinine levels from children and home air nicotine levels. Caregiver and social network member smoking behaviors will be measured by nicotine biomarkers; both test results will be the basis for incentive payments. Asthma control will be evaluated using validated questionnaires and review of the participant's electronic health record.

What participants receive

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

  • Incentive planBehavioural

    Also called Contingency management

    The caregiver and designated social network member can each receive monthly financial incentives over the 6 month time interval. Additional monthly incentives will be received at 3- and 6-months if the participant's previous two monthly biomarker levels were below the lower-limit cutoff.

  • Smoking cessationBehavioural

    Also called Tobacco cessation

    Participants who wish to quit smoking will be referred upon study recruitment to the smoking cessation program that is provided at no-cost by the Maryland Department of Health and Mental Hygiene (DMMH). The DMMH provides standard counseling and nicotine replacement pharmacotherapies for clients and is offered online or at six health centers throughout Baltimore City.

What is being measured

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

  1. Pediatric secondhand smoke exposures

    Monthly measurement of pediatric secondhand smoke exposures. Secondhand smoke exposures will be measured using salivary cotinine levels.

    Measured: 6 months

Secondary outcomes (2)
  1. Nicotine biomarkers

    Monthly measurements of nicotine biomarkers to objectively assess tobacco usage. This will serve as the trigger for monthly financial incentives for those allocated to the intervention group.

    Measured: 6 months

  2. Air nicotine

    Home air nicotine levels will be measured to assess if tobacco-derived indoor air pollutant levels will decline with the intervention. Air nicotine levels will be acquired through passive air samplers and measured using gas chromatography.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study testing Incentive plan and Smoking cessation in people with Asthma and Incentives, run by Johns Hopkins 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 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 20 Nov 2018. 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?

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?

Pediatric secondhand smoke exposures (time frame: 6 months). 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 NCT03099811, 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 20 Nov 2018.
