NCT04717544

Brief Summary

The study will evaluate a sustainable tobacco screening, treatment intervention, and cessation program implemented within both Los Angeles County (LAC)-Department of Health Services (LACDHS)-operated outpatient primary care clinics and in LAC-Department of Mental Health (LACDMH)-operated community mental health clinics. This is a three year implementation study funded by the University of California Office of the President Tobacco Related Disease Research Program (TRDRP). This project will support the implementation of smoking cessation services delivered in LACDHS and LACDMH clinics and will evaluate the effectiveness and feasibility of these services.

Outcome Measures

Primary Outcomes (3)

  • Smoking Cessation Rate

    The primary outcome is to determine if there will be higher rates of smoking cessation in the intervention sites as compared with matched non-intervention sites. In order to measure these rates, study participants will be asked to complete two objective measures collected at 3-month, 6-month and 12-month follow-up. These measures include a carbon monoxide breathalyzer (piCO+smokerlyzer) and urinary rapid dipstick cotinine test (NicCheck). A participant will count as having quit if they reported having abstained from smoking cigarettes/cigars for seven consecutive days and if this report is corroborated by carbon monoxide and cotinine testing.

    Change in carbon monoxide and cotinine levels from Baseline at 3 months

  • Smoking Cessation Rate

    The primary outcome is to determine if there will be higher rates of smoking cessation in the intervention sites as compared with matched non-intervention sites. In order to measure these rates, study participants will be asked to complete two objective measures collected at 3-month, 6-month and 12-month follow-up. These measures include a carbon monoxide breathalyzer (piCO+smokerlyzer) and urinary rapid dipstick cotinine test (NicCheck). A participant will count as having quit if they reported having abstained from smoking cigarettes/cigars for seven consecutive days and if this report is corroborated by carbon monoxide and cotinine testing.

Study Arms (2)

Intervention Arm

ACTIVE COMPARATOR

Healthcare providers from clinics participating in the intervention refer existing clients to study coordinators for smoking cessation services, wherein the coordinators link clients to the smoking cessation services, which include: 1) a weekly cognitive-behavioral therapy smoking cessation (CBT) counseling group; and 2) smoking cessation medication, which include varenicline (Chantix), bupropion (Zyban) and nicotine patches, gum, and lozenges. Clients interested in these medications will meet with the prescribing clinician to help choose the best prescription option. In addition to linking clients to the smoking cessation services, coordinators will invite clients to participate in the outcome study. Existing clients can sign-up for these services and/or the outcome study directly with the study coordinators and do not require a healthcare provider referral.

Behavioral: Intervention Arm

Treatment As Usual Arm

NO INTERVENTION

Existing clients can be referred to the outcome study by their healthcare providers from clinics designated as TAU or they can sign-up directly with the study coordinators.

Interventions

The smoking cessation intervention will include 1) a six-week, 60-75 minute weekly cognitive-behavioral therapy (CBT) smoking cessation counseling group; and 2) smoking cessation medication include varenicline (Chantix), bupropion (Zyban) and nicotine replacement therapy (NRT). Dispensing these medications will include a 15-minute medication management visit with a prescribing clinician. Clients will choose their own preferred treatment. The standard prescription for NRT will include a transdermal patch at a dose that approximates for current average mg of nicotine intake and nicotine gums or lozenges (in either 2 mg or 4 mg strengths). Prescription for varenicline will be 0.5 mg once daily for three days, then 0.5 mg twice daily for the next four days, then 1 mg twice daily thereafter. Absent any contraindications to the drugs listed above, bupropion (Zyban) 150mg will be offered and prescribed once daily for one week, following by bupropion 300 mg once daily thereafter.
