About

The primary objective of this study is to conduct a 3-arm randomized controlled trial (RCT) that compares the effectiveness of three multi-component interventions that are embedded in HIV outpatient clinics (OPCs): 1)3As+Referral to the national quitline: Ask about tobacco use, Advise to quit, Assist with brief counseling and Refer to Viet Nam's national Quitline; 2) AAA+ +Counsel (Counsel=6-session cessation counseling intervention adapted for patients living with HIV/AIDS (PLWH) and delivered by a trained, onsite nurse; and 3) AAA+Counsel+N (N=nicotine replacement therapy (NRT)). The main outcome is biochemically validated 6-months smoking abstinence. The investigators will recruit and randomize 672 patients across 13 outpatient clinics (OPCs) (48 per site, 16 per arm). The investigators will also recruit 75-nonsmokers to participate in a single survey to assess food safety. Therefore, the total sample = 747 patients.

Full description

This research has three phases. For Aim 1 the investigators will conduct a formative assessment to inform further modifications to the intervention components. Participants in Aim 1 will be patients of the outpatient clinics (OPC) or health care providers who work there. Patients who use tobacco will be asked to participate in individual interviews (n=24 ). The investigators will conduct key informant interviews with health care providers from 3 OPCs (n=28) to adapt the intervention to the OPC clinical context. The investigators will then conduct a pilot test of ARM 1 and 3 in one OPC with 16 patients. The recruitment and enrollment process will be the same as described for Aim 2. For Aim 2 the investigators will conduct a three-arm randomized controlled trial (RCT) to compare the effectiveness of three interventions aimed at increasing tobacco cessation rates among people living with HIV/AIDS (PLWH). Patients (n=672) will be recruited and enrolled from the 13 OPCs. All enrolled patients will complete a baseline survey in person. This survey will be administered once eligibility is established and consent is obtained. The consent and survey will last 30 minutes. Follow up surveys will occur at 3-, -6 and 12-months after enrollment. Follow up surveys will be conducted by telephone. At 6-months follow up, patients who report smoking abstinence will be asked to come in person to the OPC and will complete a carbon monoxide test to validate self-report. The investigators will conduct baseline, 12 and 18 month surveys with all health care providers in the study sites in person (n=98). For Aim 3 the investigators will conduct a post intervention (12-month) assessment of factors associated with implementation effectiveness and potential for sustainability. This includes repeating the health care provider surveys and Key informant interviews. The investigators will conduct baseline, 12 and 18 month surveys with all health care providers in the study sites in person (n=98). For Aim 4 the investigators will enroll 75 more patients who are non-smokers for a total of (n=747) patients and assess the relationship between food insecurity and tobacco use among PLWH (75 smokers and 75 non-smokers), which includes administering the Household Food Insecurity Access Scale (HFIAS) survey to patients at baseline and 6-months.
