Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

California Smokers' Helpline will conduct a randomized trial to evaluate 3 strategies of services and/or incentives on smoking cessation rates. This project has the following specific aims:

1. To increase tobacco cessation among Medi-Cal beneficiaries who currently smoke, and to improve the management of diabetes and other chronic disease by means of tobacco cessation.
2. Demonstrate that tobacco cessation benefits that are well promoted and barrier free and include modest incentives, are effective in reducing smoking prevalence, lowering Medi-Cal health care costs, and improving health outcomes for diabetes management in particular.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The mission of the California Department of Health Care Services (DHCS), California's single State Medicaid Agency, is to preserve and improve the health status of all Californians by operating and financing programs delivering effective health care services to eligible individuals. Medi-Cal (California's Medicaid Program) is the largest purchaser of health care in the state, serving over 7.5 million beneficiaries. Approximately half of all Medi-Cal beneficiaries receive their health care through managed care plans, while the other half receive care on a fee-for-service basis.

DHCS programs are designed to emphasize prevention-oriented health care measures (such as quitting smoking) that improve health and well-being, and ensure effective expenditure of public resources to serve those with the greatest health care needs. This study (MIPCD) aligns with the goals and objectives of the DHCS Strategic Plan, which states, "DHCS supports and values healthy lifestyle behaviors, and aims to promote the use of preventive, health improvement, and wellness services/activities."

The primary intervention in this study will be the internationally recognized, California Smokers' Helpline (Helpline) operated by the University of California, San Diego (UCSD). Established in 1992, more than 50% of the Helpline's clients are Medi-Cal members. In this study, the Helpline will: operate a fully functioning quitline call center with trained personnel and live capabilities in English, Spanish, Mandarin, Cantonese, Korean and Vietnamese; assess eligibility for the randomized trial; obtain consent for participation in the trial; send individually tailored self-help materials to registered participants; provide one-on-one telephone counseling, including a comprehensive, pre-quit planning session and up to four relapse-prevention sessions; evaluate the services provided; maintain detailed, confidential records of each beneficiary's cessation activity and receipt of incentives and services. Callers with a valid Medi-Cal ID who have diabetes or other eligible condition(s) and provide consent for the study will be randomized into one of the three arms of the trial. The arms of the trial are detailed below:

1. Group 1 (Policy A) - current policy: beneficiaries who call the Helpline will get free counseling and a certificate of enrollment, which is required in order for them to obtain free nicotine replacement therapy (NRT) from their pharmacy, four weeks' worth at a time. Beneficiaries can receive two courses of treatment per year.
2. Group 2 (Policy B1) - a new policy in which beneficiaries who call the Helpline get free counseling and have free nicotine patches shipped directly to their home, with no limit on the number of quit attempts they can make in a year.
3. Group 3 (Policy B2) - a variant of B1 in which beneficiaries will get free counseling and free nicotine patches shipped directly to their home, with no annual limit on quit attempts. Participants will also get an added incentive to adhere to the counseling program, in the form of gift cards worth $20 for their initial counseling call and $10 for each additional follow-up counseling call (up to five sessions total, or $60).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Telephone counseling

One-on-one, proactive telephone counseling to quit smoking; The content of the counseling addresses both behavioral and cognitive issues that the individual smoker faces in his/her attempt to quit. Counseling begins immediately after intake, if the client is available for a 30-minute session or by appointment at the clients' convenience. Counseling includes a comprehensive pre-quit session (to include motivation, planning, setting of a quit date and the discussion of quitting aids including nicotine patch use) plus up to four proactive follow-up calls. The follow-up calls (about 10 minutes) will be scheduled as follows: a reminder call if the quit date is more than one week out for the initial counseling, on the quit date, 4-7 days after the quit date, and 10-14 days after the quit date.

Group Type EXPERIMENTAL

Telephone counseling

Intervention Type BEHAVIORAL

Telephone counseling is conducted in the appropriate language (Spanish and English) by counselors at the California Smokers' Helpline. Counselors use a structured protocol and there is a record for each call. Quantitative information that will be available for analysis include: timing, length, and frequency of counseling calls.
