Cultural Adaptation and Piloting of a Smoking Cessation Intervention for Smokers With HIV

Not Applicable

Completed

• Conditions: Cigarette Smoking; Hiv
• Interventions: Behavioral: Computer delivered smoking cessation counseling

• Registration Number: NCT03580460
• Lead Sponsor: Johns Hopkins University

Brief Summary

One population of tobacco users that is severely affected by the consequences of smoking is people living with HIV (PLWH). Between 40-84% of PLWH smoke, a percentage that has remained constant since the first studies of smoking in HIV were conducted in the 1990's. Overall, smoking related morbidity and mortality is also greatly increased among PLWH smokers. Compared with PLWH nonsmokers, PLWH who smoke have more than 5 times the risk of non-HIV-related mortality and almost 4 times the risk of all-cause mortality. Compared with the general population, incidence ratio of smoking related cancers (eg, lung, head, neck, bladder and esophageal) is more than 5 times higher. At a critical time when advances in HIV care are providing an opportunity for prolonged life, smoking is significantly impeding the health of PLWH.

To produce meaningful changes in smoking, however, treatment will have to be acceptable and engaging to this population as well as feasible and sustainable to implement in a busy clinic. Novel technology-based interventions that incorporate evidence-based behavioral and pharmacologic interventions for smoking and are culturally tailored offer real solutions to these implementation barriers. Research shows that internet- or computer-delivered interventions (CDI) that are tailored and interactive can be efficacious in reducing smoking and are significantly more effective than usual care or written self-help materials. CDIs can also be readily adapted to different sociodemographic characteristics of a patient population because content is modular and menu driven. Moreover, technology-based interventions appear as effective as counselor-delivered interventions in reducing smoking. This growing body of evidence strongly suggests that these interventions offer promise in reducing smoking, the potential to reach significantly more patients, and the ability to overcome barriers of cost, implementation, and cultural nonspecificity. The goal of this pilot study is test to examine feasibility, acceptability of a computer-delivered smoking cessation intervention for PLWH, and to determine if intervention participation results in increased readiness to quit smoking and increased confidence in ability to quit smoking.

The goal of this pilot randomized controlled trial (RCT) is study is test to examine feasibility, acceptability of a computer-delivered smoking cessation intervention for PLWH, and to determine if intervention participation results in increased readiness to quit smoking and increased confidence in ability to quit smoking.To pilot test the computer-delivered intervention among 40 individuals with HIV receiving care in an urban HIV clinic in a small Randomized Controlled Trial 2a) To determine intervention effect on 1) readiness to quit smoking 2) increased confidence in ability to quit smoking 2) uptake of smoking cessation therapy, including a. Quit Line, b. Nicotine replacement therapy c. Pharmacotherapy (varenicline, Wellbutrin) Hypothesis: Investigators hypothesize that intervention participation will be associated with 1) increased readiness to quit and confidence in quitting smoking and 2) increased engagement with smoking cessation services.

2b) To examine feasibility and acceptability of delivering the computer-delivered smoking cessation counseling in this setting.
