A Peer Navigator Model to Improve Quit Attempts and Smoking Cessation Rates Among HIV-positive Smokers (P-NAV)

Intervention / Treatment
Detailed Description
Aims - The specific aims are to examine: (1) the feasibility, acceptability, and initial efficacy of Peer Navigation for Social Support - Smoking in a 24-week randomized pilot study; (2) to compare the effect of Peer Navigation for Social Support, relative to standard care, on mechanisms thought to underlie smoking abstinence in HIV-positive smokers.
Methodology - The investigators will adapt an existing, highly effective peer navigation training program to increase engagement in care within the HIV clinic. The peer navigator for smoking cessation will be a former daily smoker who quit smoking 1-2 years ago and has remained smoke-free. The investigators will train the peer navigator, enroll 6 HIV-positive smokers to test the intervention, and finalize the protocol. The investigators will refine the protocol based on feedback from the peer navigator, the 6 participants, and the study nurses. Next, the investigators will conduct a pilot randomized trial (N = 72) to test the feasibility, acceptability, and initial efficacy of peer navigation in a randomized, 2-group, repeated measures design. The investigators will randomize 36 HIV-positive smokers to each condition: Peer Navigation or standard care. Assessments will be collected at baseline, and at 4-, 12-, and 24-weeks.
Participant Population - Participants for this study will include 78 participants recruited from Providence, Rhode Island.

Experimental: peer navigation social support for smoking cessation
36 HIV-positive smokers will have a 30-minute session with the study nurse to discuss smoking cessation.
They will also discuss the importance of social support for quitting and the role of a Peer Navigator.
Those participants who set a quit date will choose medication/s in collaboration with the nurse and/or physician.
The Peer Navigator will be introduced and will reinforce adherence to medication.
The Peer Navigator will ensure that the patient picks up the medication, and will help to manage side effects via physician/nurse consultation.
The Peer Navigator will provide social support for quitting via weekly phone calls for 12 weeks.
|
Standard guidelines will be used for brief advice for smoking cessation based on the 5A's.
Also, motivational interviewing/guidance will also be used to determine whether enhanced treatment (using a Peer Navigator to navigate smoking cessation, obtain medication and treatment, improve adherence to treatment, and provide social support for quitting) will increase participant's quit attempts and smoking cessation rates.
|
Active Comparator: Standard Condition
36 HIV-positive smokers will receive standard care.
Participants will meet for a 30-minute session with a study nurse.
They will receive counseling based on the 5A's.
The nurse will ask about current smoking habits, advise the participant to quit, assess readiness to quit, and assist by providing resources (community programs, Quit line phone number).
The nurse will calculate Lung Age which will serve as a motivation tool to encourage smokers to quit.
Those willing to set a quit date will be instructed to call their physician for cessation medication and will provided with the National Cancer Institute self-help pamphlet.
Those participants not willing to set a quit date will be instructed to contact their physician when they are ready.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Feasibility and Acceptability
Time Frame: Week 24
|
Session attendance (recorded as a continuous variable ranging from 1 to 4 study sessions).
|
Week 24
|
Quit Attempts
Time Frame: Week 24
|
A quit attempt is defined as a period of 24 hours of no cigarette smoking
|
Week 24
|
Point prevalence abstinence
Time Frame: Week 24
|
Biochemically verified 7-day point-prevalence abstinence.
Point-prevalence abstinence will be verified by saliva cotinine radioimmune assay analysis (cutoff value of < 15 ng/ml) for stated abstinence of 7 days or longer in those not currently using NRT or other nicotine-containing products.
Self-report will always be overridden by objective verification of abstinence in the final analyses.
Breath samples for CO will be obtained at each study visit.
|
Week 24
|
Treatment Satisfaction
Time Frame: Week 24
|
CSQ-8 will be used to compare treatment satisfaction by study condition.
|
Week 24
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in social support for quitting from baseline to week 12
Time Frame: Week 12
|
Assessed using the Partner Interaction Questionnaire, which assesses negative and positive support for quitting.
Participants will be instructed to include all forms of support for quitting (including PN support if assigned to the PNSS-S condition).
|
Week 12
|
Change in self-efficacy for smoking cessation from baseline to week 12
Time Frame: Week 12
|
Contemplation Ladder, a one-item Likert-type scale (rating 1-10).
In participants who set a quit date, adherence to pharmacotherapy will be measured via participant self-report and pharmacy refill report at each study session.
