Smoking Cessation Intervention Including Health Navigators to Address Unmet Social Needs of Parents Who Smoke

Background: The goal of this study is to address parental smoking and social adversity, which can present an obstacle for smoking cessation, in order to decrease childhood exposure to second-hand cigarette smoke. To address these factors, this study includes a smoking cessation intervention for parents and legal guardians recruited in pediatric clinics (CanCEASE), as well as the support of a Health Navigator (HN) to work with the participant towards the resolution or mitigation of unmet social needs. Participants: The research team will recruit one thousand participants from pediatric outpatient clinics within two healthcare centres in and around the city of Montreal, Canada, over the course of 2.5 years. Eligible persons are parents and legal guardians, of any sex and gender, accompanying children under 18 to their scheduled medical appointments, and who report at least one social risk in selected areas (i.e., employment, housing stability, ability to pay for utilities, financial resource strain, food security, transportation, childcare, parent education and health literacy). Participants must also be 18 years old or older with sufficient proficiency in French or English to complete the interviews and questionnaires. In households in which both parents smoke, only one will be eligible to participate, but smoking cessation information will be offered to both. Families presenting at the clinic for an urgent medical issue are not eligible to participate. Intervention: Participants will be divided into control group (care as usual with CanCEASE at the end of the study period) and intervention (CanCEASE + Health navigator). All participants will complete questionnaires at Baseline, 6 and 12 months. The intervention group will receive CanCEASE at the end of each questionnaire. Controls will receive CanCEASE at 12 months. The intervention group will have the possibility to meet with the HNs and will be invited to commit to at least two sessions (i.e.: evaluation and a follow up), with the option to book more time as needed. Aims and hypotheses: Examining how effective the combination of CanCEASE with HN support is in helping parents with unmet social needs quit smoking. Investigators will also examine the effects of the intervention on status of unmet social needs, if the intervention was implemented as planned and well accepted by clinics and participants, and what is the cost of the intervention for each person who quits smoking.
