Summary

To determine the efficacy of an algorithm designed to recommend smoking cessation-related pharmacotherapy options to the primary care providers of smokers living with HIV/AIDS.

Detailed description

Smoking remains the leading cause of preventable death and disability in the United States. Whereas smoking has declined significantly among individuals in the general population, it is clustered in populations of vulnerable individuals such as people living with HIV/AIDS (PLWH) in whom smoking prevalence rates and resulting comorbidity rates remain high. Medical advances in the treatment of HIV have resulted in substantial increases in life expectancy among PLWH and as a consequence PLWH smokers are now, more than ever, at heightened risk for tobacco-related illnesses and death. PLWH smokers engaged in treatment lose more years of life due to smoking now than to HIV disease. Although PLWH smokers engaged in HIV care typically see a medical provider every 4-6 months, smoking cessation treatment and referral is often not part of routine HIV care. While 94% of HIV treatment providers indicated that they would be willing to provide smoking cessation services to their patients, few have received training in how to provide smoking cessation services. With seven first line pharmacotherapies available for smoking cessation, development of algorithms to assist providers in selecting the most appropriate pharmacotherapy is an important but untested strategy to increase smoking cessation in PLWH. The purpose of this proposal is to conduct a mixed efficacy/effectiveness trial comparing an algorithm treatment with prescription cost off sets and quit line referral (AT) to an enhanced Treatment as Usual (quit line referral only; eTAU) group. Six hundred PLWH smokers will be recruited at the University of Alabama at Birmingham, University of Washington, and Fenway Health HIV clinics and will be randomized to receive AT or eTAU. All AT smokers will receive active treatment for twelve weeks regardless of stated motivation or intention to quit. eTAU smokers will be referred to quit line services and HIV providers may elect to treat smoking as part of standard of care. Participants will remain in the study for 12 months.

Interventions

Type	Name	Description
DRUG	Algorithm Treatment	Varenicline was selected as the first line of treatment for patients willing to take a medication twice per day and wanting cessation. Following varenicline, bupropion and then NRT are subsequent options. In terms of preference for NRT, nicotine patches would be the first option followed by lozenge, gum, inhaler, and nasal spray. The order of NRT within the algorithm is based upon patient familiarity and number of clinical trials supporting their use. Combination NRT (e.g., patch and lozenge) or adding NRT to varenicline or bupropion is offered to participants who have made an unsuccessful quit attempt with these medications in the past. If none of these medications are appropriate, then the participant is offered counseling only.
OTHER	Quitline only	eTAU participants will complete the same algorithm questions but will not have this information sent to their provider, although their provider may elect to prescribe medication as part of standard of care. Participants will be referred to a quitline for behavioral support services for cessation.
