CanCEASE: A Brief Digital Screening Tool to Address Tobacco and E-cigarette Use in Pediatric Medical Care
Study Details
Study Description
Brief Summary
Tobacco use is the single greatest preventable cause of morbidity and mortality in Canada, accounting for 48,000 deaths and $16.2 billion annually in attributable health-related costs. Parents who smoke are often medically underserved and visit their child's doctor more than their own; 25% of all adult smokers have children seen in child healthcare. When parents quit smoking, their life expectancy is increased by more than 10 years, tobacco-related poor pregnancy outcomes are eliminated, children's risk of becoming smokers decreases 4-fold, families have more money for necessities, and children are less likely to suffer from diseases caused by tobacco smoke exposure.
Despite free tobacco cessation services in every province and widespread insurance coverage of NRT, parental tobacco screening and cessation support rarely happens in pediatric care, thus there is potential for major health benefits from a routinely delivered tobacco control program to parents in this setting.
The investigators will conduct a 12-month single centre, pragmatic, single-blind pilot RCT of CEASE vs. usual care of 40 parents who use cigarettes and/or vaping products whose children are seen in pediatric clinics at the CHU Sainte-Justine. A similar trial, CEASE-A will be conducted with 40 adolescents ages 14-17.
Objectives:
-
Perform a pilot RCT of the Clinical Effort Against Secondhand Smoke (CEASE) intervention in Canada. CEASE is an evidence-based parental smoking cessation intervention to ensure that every parent who uses cigarettes and/or nicotine vaping products and visits their child's pediatrician receives nicotine dependence treatment
-
Conduct an ancillary pilot RCT of CEASE-A to deliver evidence-based support for adolescents who use tobacco and/or nicotine vaping products Outcomes include pilot process outcomes and preliminary effectiveness outcomes to assess feasibility and inform the preparation of a future large-scale RCT.
This pilot RCT will provide the data necessary to plan a fully powered RCT assessing the effectiveness of CEASE and CEASE-A for smoking and vaping cessation.

Detailed Description
Background: Tobacco use is the single greatest preventable cause of morbidity and mortality in Canada, accounting for 48,000 deaths and $16.2 billion in attributable health-related costs annually. Twenty-five percent of all adult smokers have children who are seen in child healthcare offices. When parents quit smoking, their life expectancy is increased by more than 10 years, tobacco-related poor pregnancy outcomes are eliminated, children have 4-fold lower risk of becoming smokers, families have more money for necessities, and children are less likely to suffer from diseases caused by tobacco smoke exposure. Parents who smoke are often medically underserved and visit their child's doctor more than their own. Thus, a routinely delivered tobacco control program to parents in the pediatric context would provide a major health benefit to the nation. Yet, parental tobacco screening and cessation support happens less than 5% of the time in pediatric practices despite free tobacco cessation quitlines and services in every province and widespread insurance coverage of nicotine replacement therapy (NRT).
Specific Objectives:
Primary objective:
• Perform a pilot randomized controlled trial (RCT) of the Clinical Effort Against Secondhand Smoke (CEASE) intervention in Canada. CEASE is an evidence-based parental smoking cessation intervention to ensure that every parent who uses cigarettes and/or nicotine vaping products and visits their child's pediatrician receives nicotine dependence treatment.
Secondary objective:
• Conduct an ancillary pilot RCT of CEASE-A, an extension of CEASE, to deliver evidence-based support for adolescents who use tobacco and/or nicotine vaping products.
These pilot RCTs will inform whether full scale RCTs of CEASE/CEASE-A are feasible.
Design: The investigators will conduct a 12-month single centre, pragmatic, single-blind pilot RCT of the CEASE intervention vs. care as usual (ratio 1:1) of 40 parents who use cigarettes and/or vaping products whose children are seen in pediatric clinics at the CHU Sainte-Justine. A similar trial will be conducted with 40 adolescents ages 14-17 with the CEASE-A intervention.
Population: For the primary objective, the population will be parents of children 0-17 years old and who use tobacco or nicotine vaping products. "Users" will be defined as those answering "Yes" to the screening question: "Have you smoked a single cigarette or used nicotine vaping products, even a puff, in the past 7 days?"
For the secondary objective (CEASE-A), the population will be adolescent patients aged 14-17 years who use tobacco or nicotine vaping products. "Adolescent users" will be defined as those answering "Yes" to the screening question: "Have you smoked a single cigarette or used a nicotine vaping product, even a puff, in the past 7 days?"
Intervention: The CEASE intervention is a parental tobacco and vaping cessation intervention delivered in pediatric practices, leveraging existing healthcare and community resources. It integrates evidence-based tobacco use screening and cessation assistance into routine visits to pediatric clinics. CEASE is based on the 5A's model of smoking cessation: Ask about smoking, Advise to quit, Assess readiness to quit, Assist with a quit plan and Arrange follow-up. Given that CEASE is a one-time intervention, "Arrange" is removed, and the fourth step "Assist" is divided into two parts: a) providing phone/text/app quit support and b) providing NRT.
CEASE-A follows the same format at CEASE, but is modified slightly to address smoking and vaping in the adolescent target population
Control: The control condition will be care as is usually delivered in participating clinics with the possibility of receiving direct linkage with cessation services delivered via CEASE/CEASE-A at the end of the 6-month study period. Current practice does not include routine provision of assistance for parental/adolescent smoking or e-cigarette cessation (e.g., referral to quitlines, NRT prescription).
Follow-up includes three data collection time points at 1-, 3- and 6-months after recruitment.
Outcomes
Outcomes will include pilot process (feasibility) outcomes to ensure a large RCT is feasible, as well as preliminary effectiveness outcomes to inform the preparation of a future large-scale RCT.

Key informant interviews or written survey with front desk staff, and clinical staff to document impacts of the intervention on clinic workflow.
Effectiveness outcomes
-
Abstinence at 6 months: % of parental/adolescent users who report 7-day abstinence at 6-month follow-up. We will collect self-reported smoking and vaping status using the validated single items "Have you smoked a single cigarette, even a puff, in the past 7 days?" and "Have you used a nicotine vaping product, even a puff, in the past 7 days?"
-
Cotinine-confirmed quit: Participants who self-report 7-day abstinence at 1, 3 and/or 6 months will receive a sampling kit by mail along with instructions on how to collect the urine for biochemical confirmation of smoking/vaping cessation
Secondary effectiveness outcomes
-
Intent to quit smoking and/or vaping at recruitment and follow-up
-
Quit attempts at 1-, 3- and 6- months
Statistical plan and sample size calculation:
For this pilot RCT, process outcomes will be examined using descriptive statistics and compared between intervention and control groups using chi-square tests.
Sample size calculation To estimate participation rate, using a sample size of 40 participants per age group will allow for a 95% confidence interval within 15% of the estimate obtained. As such, if participation rate in the feasibility study of 60% is observed, the 95% C.I. would be (44.2%, 75.8%). As recruitment rates may differ between adult and adolescent participants, the investigators will enroll 40 parents and 40 adolescents for this pilot study to obtain two participation rates estimates.
Relevance The proposed pilot RCT will provide the data necessary to plan a fully powered RCT assessing the effectiveness of CEASE and CEASE-A for smoking and vaping cessation. It will also help test this evidence-based intervention in a new population, adolescents, with high potential to act early in the life course and meaningfully reduce the societal burden associated with tobacco use.
