The purpose of this pilot study was to examine the effectiveness of an 8-week, nurse-managed, peer-led smoking cessation intervention among HIV-positive smokers. The intervention was based on the Agency for Health Care Policy and Research Smoking Cessation Clinical Practice Guideline and was delivered by an ex-smoker who was HIV positive and had been trained by an advanced practice nurse to deliver cessation counseling. Eight male HIV-positive smokers were assigned to the intervention group and received (a) 21 mg nicotine patch therapy for 6 weeks, (b) weekly face-to-face or telephone counseling, and (c) skills training that included substitute strategies for dealing with not smoking. Those participants assigned to the control group received written self-help materials for smoking cessation. Abstinence rates at end of intervention and 8 months were compared between groups. At end of treatment, 62.5% of intervention group participants were biochemically confirmed as abstinent from smoking compared with 0% in the control group. Eight-month abstinence rates were 50% among the intervention group compared with 0% in the control group.

Design and Setting

The research design was a two-group, quasi-experimental, longitudinal approach. The Ohio State University National Institutes of Health-funded AIDS Clinical Trials Unit (ACTU), which is located in the Infectious Diseases Clinic, served as the setting for the investigation. The ACTU provides primary and research care for more than 1,500 patients.

Sample Participant Inclusion Criteria and Recruitment

Eligibility criteria included the following: (a) male or female 18 years of age or older, (b) self-reported smoking of at least 10 cigarettes a day for

Sample Characteristics

During a 1-month enrollment period, a total of 15 participants contacted the ACTU and requested to participate in the study. All 15 participants were male and met the eligibility requirements. The intervention group contained 8 participants, whereas the control group included 7 participants. Sociodemographic and smoking history characteristics did not differ significantly by group (see Table 1). The participants were an average of 40 years of age and had smoked more than a pack of cigarettes

Discussion

This preliminary study represents the first examination of a smoking cessation intervention among HIV-positive smokers, a group specifically at risk for acute bacterial pneumonia, due to their HIV status, and other smoking-related diseases, including coronary artery disease. The intervention, which was based on the scientifically valid AHCPR guideline, was delivered by a credible HIV-positive peer educator. As an ex-smoker, the peer educator was viewed positively by the target population. In

Nursing Implications

Dramatic reductions in HIV-associated illnesses and deaths have followed the recent introduction and widespread use of highly active antiretroviral therapy (Detels et al., 1998; Palella et al., 1998). For many individuals, HIV disease has become a chronic illness. As such, health promotion and risk-reduction activities delivered by nurses will become increasingly important dimensions of HIV care. Although the prevalence of opportunistic infections has decreased significantly, the proportion of
