Abstract
Background In 2007, Alberta became the first Canadian jurisdiction to grant pharmacists a wide range of prescribing privileges. Our objective was to understand what factors influence pharmacists’ adoption of prescribing using a model for the Diffusion of Innovations in healthcare services. Methods Pharmacists participated in semi-structured telephone interviews to discuss their prescribing practices and explore the facilitators and barriers to implementation. Pharmacists working in community, hospital, PCN, or other settings were selected using a mix of random and purposive sampling. Two investigators independently analyzed each transcript using an Interpretive Description approach to identify themes. Analyses were informed by a model explaining the Diffusion of Innovations in health service organizations. Results Thirty-eight participants were interviewed. Prescribing behaviours varied from non-adoption through to product, disease, and patient focused use of prescribing. Pharmacists’ adoption of prescribing was dependent on the innovation itself, adopter, system readiness, and communication and influence. Adopting pharmacists viewed prescribing as a legitimization of previous practice and advantageous to instrumental daily tasks. The complexity of knowledge required for prescribing increased respectively in product, disease and patient focused prescribing scenarios. Individual adopters had higher levels of self-efficacy toward prescribing skills. At a system level, pharmacists who were in practice settings that were patient focused were more likely to adopt advanced prescribing practices, over those in product-focused settings. All pharmacists stated that physician relationships impacted their prescribing behaviours and individual pharmacists’ decisions to apply for independent prescribing privileges. Conclusions Diffusion of Innovations theory was helpful in understanding the multifaceted nature of pharmacists’ adoption of prescribing. The characteristics of the prescribing model itself which legitimized prior practices, the model of practice in a pharmacy setting, and relationships with physicians were prominent influences on pharmacists’ prescribing behaviours.

Abstract
Drug interactions involving human immunodeficiency virus protease inhibitors are common due to their inhibition of the cytochrome P450 3A4 isoenzyme. We describe the case of an HIV-infected patient treated with ritonavir-boosted darunavir who developed cushingoid features following an intra-articular injection of triamcinolone acetate. We review the probable mechanism for this interaction and describe similar cases of Cushing syndrome in patients receiving concomitant ritonavir and triamcinolone.

Abstract
The Mayo Clinic Cancer Center and Diné College received funding for a 4-year collaborative P20 planning grant from the National Cancer Institute in 2006. The goal of the partnership was to increase Navajo undergraduates' interest in and commitment to biomedical coursework and careers, especially in cancer research. This paper describes the development, pilot testing, and evaluation of Native CREST (Cancer Research Experience and Student Training), a 10-week cancer research training program providing mentorship in a Mayo Clinic basic science or behavioral cancer research lab for Navajo undergraduate students. Seven Native American undergraduate students (five females, two males) were enrolled during the summers of 2008-2011. Students reported the program influenced their career goals and was valuable to their education and development. These efforts may increase the number of Native American career scientists developing and implementing cancer research, which will ultimately benefit the health of Native American people.

Abstract
Tobacco cessation treatments have not been evaluated among Alaska Native (AN) adolescents. This pilot study evaluated the feasibility and acceptability of a targeted cessation intervention developed for AN youth. Intervention components were informed by prior focus groups assessing treatment preferences among AN youth, a social cognitive theoretical framework and feedback obtained from a teen advisory group. The intervention consisted of a weekend program where youth traveled by small airplane from their villages to stay overnight with other adolescents who quit tobacco use together. The program included recreational activities, talking circles, personal stories from elders and teen advisors, and cognitive behavioral counseling. Two intervention pilots were conducted from October 2010 to January 2011 using a non-randomized, uncontrolled study design with assessments at baseline and six-week follow-up. One village in Western Alaska was selected for each pilot with a targeted enrollment of 10 adolescents each. Participants were recruited for each pilot within five days, but recruitment challenges and ''lessons learned'' are described. The first pilot enrolled nine adolescents (all female) aged 13-16 years; all nine attended the intervention program and 78% (7/9) completed follow-up. The second pilot enrolled 12 adolescents (eight females, four males) aged 12-17 years, of which seven attended the intervention program. Six of these seven participants (86%) completed follow-up. In both pilots, participants rated the intervention as highly acceptable. A targeted cessation intervention was feasible and acceptable to AN youth. The intervention will be tested for efficacy in a subsequent randomized controlled trial.

Abstract
Multiple barriers can influence adherence to antihypertensive medications. The aim of this systematic review was to determine what adherence barriers were included in each instrument and to describe the psychometric properties of the identified surveys. Barriers were characterized using the World Health Organization (WHO) Multidimensional Adherence Model with patient, condition, therapy, socioeconomic, and health care system/team-related barriers. Five databases (Medline, Embase, Health and Psychological Instruments, CINHAL, and International Pharmaceutical Abstracts [IPA]) were searched from 1980 to September 2011. Our search identified 1712 citations; 74 articles met inclusion criteria and 51 unique surveys were identified. The Morisky Medication Adherence Scale was the most commonly used survey. Only 20 surveys (39%) have established reliability and validity evidence. According to the WHO Adherence Model domains, patient-related barriers were most commonly addressed, while condition, therapy, and socioeconomic barriers were underrepresented. The complexity of adherence behavior requires robust self-report measurements and the inclusion of barriers relevant to each unique patient population and intervention.

Abstract
University-based continuing education (CE) fulfills an important role to support the professional development of pharmacists, advance the practice of pharmacy, and contribute to societal needs for research and healthcare services. Opportunities for pharmacists to engage in new models of patient care are numerous worldwide, particularly as pharmacists' scope of practice has expanded. Approaches to CE have changed to address the changing needs of pharmacists and now include a variety of approaches to support development of knowledge and skills. There is emphasis on the learning process as well as the knowledge, with the introduction of the concept of continuing professional development (CPD).As institutions of research and education, universities are uniquely positioned to bridge the gap between academic and practice environments, providing opportunities for translation of knowledge to practice. The Faculty of Pharmacy and Pharmaceutical Sciences at the University of Alberta is a provider of CE in Alberta, Canada, where an expanded scope of pharmacy practice includes prescribing, administering injections, accessing electronic patient records, and ordering laboratory tests. In this paper, the Faculty offers views about future directions for CE, including the integration of CE with core faculty activities, expanding the audience for CE, areas of focus for learning, and partnerships. Finally, we hope to ignite dialogue with others in the profession about the role and function of university-based CE.

Abstract
A novel approach to tobacco control is to engage adolescent nonsmokers in support roles to encourage and help their parents stop smoking. This pilot study examined the feasibility and potential efficacy of a web-based support skills training (SST) intervention for adolescents to help a parent stop smoking. Forty nonsmoking adolescents 13-19 years of age (70% female, 93% White) were enrolled and randomly assigned to a health education (HE) control group (n=20) or SST (n=20). Both consisted of written materials and five weekly, 30 min, web-based, counselor-facilitated group sessions. Parents were enrolled for assessments only. Adolescents and parents completed assessments at baseline, week 6 (post-treatment), week 12 and 6-months follow-up. Both interventions were feasible based on treatment acceptability ratings, study retention and treatment compliance. The biochemically confirmed 6-month smoking abstinence rate was higher for parents linked to teens in HE (35%, 7/20) than in SST (10%, 2/20), p=0.13. About half of parents in each group reported a quit attempt since study enrollment. Teens can be engaged to help parents stop smoking. Future research is warranted on determining effective intervention approaches.

Abstract
OBJECTIVES To describe how an electronic health record (EHR) was integrated into community pharmacists' patterns of patient care and to explore factors that are related to the use of medication and laboratory value information from the EHR. DESIGN Descriptive, exploratory, nonexperimental study. SETTING Edmonton, Canada, between November 2008 and March 2009. PARTICIPANTS 16 pharmacists, 3 pharmacy technicians, and 2 pharmacy interns from primary care networks, long-term care settings, community independent and chain pharmacies, and grocery store pharmacies. INTERVENTION Qualitative interviews. MAIN OUTCOME MEASURE Pharmacists' self-reported use of EHR. RESULTS Pharmacists in a patient-centered care practice (involving medication therapy management activities) were more likely to adopt the EHR for medication history and laboratory values, whereas pharmacists whose practice was focused on medication dispensing primarily used the EHR for patient demographic and dispensing records. Six general factors influenced the use of EHR: patients, pharmacists, pharmacy, other health professionals (i.e., physicians), EHR, and environment. Access to the medical record versus EHR and timeliness were barriers specific to pharmacists in a patient-centered practice. Factors that affected EHR use for pharmacists with primarily a dispensing practice were role understanding, dispensing versus lab records, valid reasons for using EHR, and fear of legal and disciplinary issues. CONCLUSION Many community pharmacists embraced the EHR as a part of practice change, particularly those in patient-centered care practices. Practice type (patient-centered care or dispensing) greatly influenced pharmacists' use of EHR, specifically laboratory values. Because these qualitative findings are exploratory in nature, they may not be generalized beyond the participating pharmacies.

Abstract
OBJECTIVE To evaluate the literature on protease inhibitor (PI)-associated QT interval prolongation and risk for torsade de pointes in patients infected by HIV. DATA SOURCES Primary literature was identified through MEDLINE (1950-August 2011) and EMBASE (1980-August 2011), using the following search terms: antiretroviral agents, HIV, protease inhibitors, QTc, QT prolongation, and torsade de pointes. STUDY SELECTION AND DATA EXTRACTION English-language case reports of antiretroviral therapy-associated QT interval prolongation, studies of healthy volunteers, or studies that evaluated the impact of PIs on QT interval in patients infected with HIV were reviewed and selected. Article bibliographies and conference abstracts were also reviewed. DATA SYNTHESIS Several case reports, as well as in vitro data, have implicated PIs as a potential cause of QT interval prolongation and/or torsade de pointes. Saquinavir, therapeutically boosted with the potent CYP3A4 inhibitor ritonavir, was the only PI shown to be associated with significant QT interval prolongation in studies with healthy volunteers. While 1 case control study in HIV-infected patients found that nelfinavir or efavirenz, a nonnucleoside reverse transcriptase inhibitor, increased the risk of QT interval prolongation, larger prospective studies have not demonstrated any significant increase in QT interval following exposure to PIs. Similar risk factors for QT interval prolongation seen in non-HIV-infected patients, such as older age, female sex, ethnicity, cardiac conditions, diabetes mellitus, and concomitant use of other QT interval-prolonging medications, especially methadone, were risk factors identified in studies of HIV-infected patients. CONCLUSIONS PIs do not appear to independently predispose patients to QT interval prolongation. However, other risk factors (both HIV-related and non-HIV-related) may increase the risk of QT interval prolongation. Available data suggest that baseline and follow-up electrocardiogram monitoring are unnecessary precautions, but may be considered in patients who are initiating PI therapy and are on multiple medications with proarrhythmic potential and/or have multiple comorbidities, increasing the risk.

Abstract
BACKGROUND Quitlines and other evidence-based cessation treatments are greatly underutilized by smokers, limiting their public health impact. Social support is correlated with successful cessation. Thus, efforts targeting the social network of smokers could be a potential avenue to promote quitline utilization. PURPOSE This study examined the efficacy of an intervention for nonsmokers interested in helping a smoker (i.e., support people) to promote smoker utilization of the Minnesota QUITPLAN(®) Helpline. Data were collected from 2007 to 2010, and analyses were conducted from 2010 to 2011. DESIGN Two-group randomized design evaluating the support-person intervention (n=267) compared with a control condition (written materials, n=267). SETTING/PARTICIPANTS Enrolled were 534 support people (91% female, 93% Caucasian) residing in Minnesota. INTERVENTION Written materials plus three weekly telephone sessions lasting 10-30 minutes each. Based on Cohen's theory of social support, the intervention provided participants with information and skills needed to encourage their smoker to call the QUITPLAN Helpline. MAIN OUTCOME MEASURES Participants completed the Support Provided Measure (SPM) by mail at baseline and Week 4 (end-of-treatment). Helpline intake staff documented smoker calls to the Helpline through 6 months of follow-up. RESULTS The proportion of calls to the Helpline was significantly (p=0.012) greater for smokers linked to support people in the intervention group (16.1%, 43/267) than in the control group (8.6%, 23/267). The treatment effect remained significant after adjusting for support person residing with the smoker (OR=2.04, 95% CI=1.19, 3.49, p=0.010). Among support people randomly assigned to the intervention group, greater number of sessions completed was associated with increased smokers' calls to the Helpline (p=0.004). After adjusting for the baseline score, the M±SD SPM score at Week 4 was significantly higher for support people in the intervention group (16.4±3.3) than for those in the control group (15.3±3.6), p=0.002. CONCLUSIONS A support-person intervention is effective in increasing smoker utilization of the QUITPLAN Helpline. There is potential for increasing the reach of quitlines by targeting the social network of smokers. TRIAL REGISTRATION #: NCT01311830.

Abstract
IMPORTANCE OF THE FIELD Since the advent of combination antiretroviral therapy, the incidence of opportunistic infections has declined and the life expectancy of HIV-infected people has significantly increased. However, opportunistic infections, including fungal diseases, remain a leading cause of hospitalizations and mortality in HIV-infected people. With the availability of several new antiretroviral and antifungal agents, drug-drug interactions emerge as a potential safety concern. AREAS COVERED IN THIS REVIEW Relevant literature was identified using a Medline search of articles published up to March 2010 and a review of conference abstracts. Search terms included HIV, antifungal agents and drug interactions. Original papers and relevant citations were considered for this review. WHAT THE READER WILL GAIN Readers will gain an understanding of the pharmacokinetic properties of antiretroviral and antifungal agents, and insight into significant drug-drug interactions which may require dosage adjustments or a change in therapy. TAKE HOME MESSAGE Azole antifungal drugs, with the exception of fluconazole, pose the greatest risk of two-way interactions with antiretroviral drugs through CYP450 enzymes effects. Limited studies suggest the risk of interactions between antiretroviral drugs and echinocandins is much lower. The combination of tenofovir and amphotericin B should be used with caution and close monitoring of renal function is required.

Abstract
This paper describes the development and pilot testing of a 10-week cancer research education program for Navajo undergraduate students. The program was piloted at Diné College with 22 undergraduates (7 men, 15 women) in 2007 and 2008. Students completed a pre-post program survey assessing attitudes, opinions, and knowledge about research and about cancer. The program was found to be culturally acceptable and resulted in statistically significant changes in some of the attitudes and opinions about research and cancer. Combining all 13 knowledge items, there was a significant (p = 0.002) change in the mean total correct percent from baseline [70.3 (SD = 15.9)] to post-program [82.1 (SD = 13.1)]. The curriculum was adapted for a new cancer prevention and control course now offered at Diné College, enhancing sustainability. Ultimately, these efforts may serve to build capacity in communities by developing a cadre of future Native American scientists to develop and implement cancer research.

Abstract
Provincial guidelines for HIV non-occupational postexposure prophylaxis (NPEP) were implemented on January 2005 in Alberta, Canada. Human immunodeficiency virus (HIV) NPEP was provided free of charge following approval by a medical officer of health. Between 1 January 2005 and 30 June 2007, 174 individuals were prescribed NPEP; 135 (78%) were women with a median age of 24 years. Sexual assaults accounted for 68% of exposures. NPEP was completed in 49% of cases. Individuals who completed NPEP were less likely to have been exposed by sexual assault ( P = 0.04) and more likely to have received HIV follow-up testing ( P = 0.03).Individuals who received at least one HIV follow-up test were older ( P = 0.03) and more likely to have been exposed percutaneously ( P = 0.003). Those who received no follow-up testing were less likely to have filled an NPEP prescription ( P = 0.0001). New strategies are required to improve follow-up of individuals receiving NPEP, especially younger persons or sexual assault survivors.

Abstract
OBJECTIVES The practice environment in Alberta has emerged as the most unique in North America, including access to laboratory values, a province-wide electronic health record and legislation to support additional prescribing authority for qualified pharmacists. A course to help pharmacists integrate laboratory values in their medication management of patients was introduced to prepare pharmacists for these changes. The purpose of this study was to evaluate pharmacists' experience with a continuing professional development (CPD) course and its impact on pharmacists' knowledge, confidence and change in practice. METHODS A 12-week CPD course for pharmacists on interpreting laboratory values was delivered as a 2-day interactive workshop followed by three distance-learning sessions. The evaluation explored pharmacists' knowledge and confidence using laboratory values in practice, changes in practice and effectiveness of course delivery through pre- and post-course surveys and interviews. KEY FINDINGS Pharmacists' knowledge about laboratory tests and confidence discussing and using laboratory values in practice significantly improved after course completion. The blended delivery format was viewed positively by course participants. Pharmacists were able to implement learning and make changes in their practice following the course. CONCLUSIONS A CPD course for pharmacists on integrating laboratory values improved pharmacists' knowledge and confidence and produced changes in practice.

Abstract
BACKGROUND Among Alaska Native women residing in the Yukon-Kuskokwim (Y-K) Delta region of Western Alaska, about 79% smoke cigarettes or use smokeless tobacco during pregnancy. Treatment methods developed and evaluated among Alaska Native pregnant tobacco users do not exist. This pilot study used a randomized two-group design to assess the feasibility and acceptability of a targeted cessation intervention for Alaska Native pregnant women. METHODS Recruitment occurred over an 8-month period. Enrolled participants were randomly assigned to the control group (n = 18; brief face-to-face counseling at the first visit and written materials) or to the intervention group (n = 17) consisting of face-to-face counseling at the first visit, four telephone calls, a video highlighting personal stories, and a cessation guide. Interview-based assessments were conducted at baseline and follow-up during pregnancy (>or=60 days postrandomization). Feasibility was determined by the recruitment and retention rates. RESULTS The participation rate was very low with only 12% of eligible women (35/293) enrolled. Among enrolled participants, the study retention rates were high in both the intervention (71%) and control (94%) groups. The biochemically confirmed abstinence rates at follow-up were 0% and 6% for the intervention and control groups, respectively. DISCUSSION The low enrollment rate suggests that the program was not feasible or acceptable. Alternative approaches are needed to improve the reach and efficacy of cessation interventions for Alaska Native women.

Abstract
Objective: To report the results of therapeutic drug monitoring of lopinavir/ritonavir and itraconazole concentrations in an HIV-infected male who was treated for histoplasmosis. Case Summary: A 34-year-old HIV-infected man who had recently initiated efavirenz-based antiretroviral therapy was diagnosed with disseminated Histoplasma capsulatum infection. In the hospital, lopinavir/ritonavir 400 mg/100 mg twice daily replaced efavirenz to avoid etavirenz-itraconazole interactions. After 14 days of liposomal amphotericin B therapy, itraconazole solution was initiated at 150 mg twice daily for 3 days, followed by 200 mg daily. Prior to itraconazole initiation, lopinavir trough concentration was 7.4 mg/L. The lopinavir trough concentration 15 days later, after 14 days of itraconazole, was 6.8 mg/L. An itraconazole concentration measured 2 hours post-dose on day 15 of oral therapy was 1.9 pg/mL. After 2 weeks of liposomal amphotericin, urine Histoplasma antigen was 27.23 ng/mL; after 5 months of oral itraconazole therapy, it decreased to 5.24 ng/mL. Plasma HIV RNA decreased 4.26 log10 in 5 months to less than 40 copies/mL The patient has demonstrated marked clinical improvement. Discussion: In this case, dosing recommendations of itraconazole 200 mg daily with lopinavir/ritonavir were appropriate. Lopinavir trough concentrations were not significantly different following the addition of itraconazole and were above the minimum target of 1 mg/L in treatment-naive patients. The itraconazole concentration was above the recommended concentration of at least 1 μg/mL. Conclusions: The dose of itraconazole was reduced to 200 mg daily as recommended by current guidelines, and therapeutic drug monitoring of both itraconazole and lopinavir concentrations confirmed that no further dosage adjustments were necessary.

Abstract
Background Current guidelines for the use of antiretroviral (ARV) therapy during pregnancy recommend that women be offered treatment with combination ARV therapy used in nonpregnant HIV-infected individuals. It is unclear whether the risk of ARV-related adverse drug reactions (ADRs) is increased during pregnancy. Objective To evaluate the frequency and severity of ADRs likely caused by ARV therapy in pregnant women who are HIV-positive. Methods A retrospective analysis of HIV-infected women who received ARV therapy during pregnancy and delivered between January 1997 and February 2006 was conducted. Incidence of maternal ADRs was determined through evaluation of laboratory findings, documented physical examinations, and patient self-reports. An AIDS Clinical Trials Group severity grading scale was applied to the ADRs. Cause-effect relationship was adjudicated based on the Naranjo probability scale and, if causality was found, that information was included. Results There were 103 women who accounted for 133 pregnancies that resulted in deliveries. Of the 111 pregnancies in which treatment was received, regimens included 26 nucleoside reverse transcriptase inhibitor monotherapy, 40 nonnucleoside reverse transcriptase inhibitor (NNRTI)–based, 44 protease inhibitor (PI)–based, and 1 PI/NNRTI combination therapy. Ninety-eight ADRs were documented in 49 pregnancies. The most common ADRs were gastrointestinal (n = 48), followed by central nervous system symptoms (n = 15), anemia (n = 15), elevated liver/pancreatic enzyme levels (n = 11), and cutaneous reactions (n = 8). Severe ADRs included elevations in liver/pancreatic enzymes (n = 3), nausea and vomiting (n = 3), and anemia (n = 2). Seven women required a change in therapy due to an ADR. Conclusions Approximately 7 ADRs were reported for every 10 pregnancies in this cohort. Most ADRs were mild to moderate. Short exposure times in most women (second and third trimester) may have accounted for the lack of long-term toxicities. Although ADRs did not pose a major barrier to use of ARVs in pregnancy, close monitoring of pregnant women receiving ARV therapy continues to be warranted.

Abstract
OBJECTIVES We evaluated the effectiveness of a program that includes routine opt-out prenatal HIV screening, combination antiretroviral therapy (ART), and a multidisciplinary team in preventing perinatal HIV transmission. METHODS A retrospective analysis was performed on HIV-infected pregnant women in northern Alberta, Canada, who delivered between January 1, 1999, and February 28, 2006. RESULTS Ninety-eight women had 113 deliveries. Forty-three percent were diagnosed with HIV infection through prenatal screening. Approximately 60% of HIV-infected pregnant women were Aboriginal, with 45% reporting alcohol use and 42% illicit drug use during pregnancy. The use of combination ART during pregnancy increased throughout the study period; 89% or more received combination ART from 2004 through 2006. Only 1 of the 111 infants (0.9%) was confirmed to be HIV infected, and that infant was born to a woman with no prenatal care. CONCLUSIONS High rates of HIV testing using an opt-out approach, combined with efforts by a multidisciplinary team, resulted in a low rate of perinatal HIV transmission in our cohort. The added value of retesting high-risk women late in pregnancy or with rapid HIV tests at the time of delivery should be explored.

Abstract
BACKGROUND Nonsmokers have a potentially supportive role in tobacco cessation efforts. The present study examined the feasibility, acceptability, and potential efficacy of a telephone-based intervention for nonsmoking support persons. METHODS A total of 59 support persons (mean age = 36 years, 92% female, 95% White) were randomly assigned to a control condition (N = 30; written materials only) or to a social cognitive theory-based intervention (N = 29; written materials and 5 weekly, 20- to 30-min telephone counseling sessions). Both support persons and smokers completed assessments separately by mail at baseline and at weeks 6 (end of treatment) and 26. RESULTS Two thirds of the smokers reported low-moderate levels of motivation to quit at baseline as assessed by the contemplation ladder. Study retention rates were excellent, with 95% of both support persons and smokers completing the week 26 assessment. Moreover, 86% of support persons in the intervention group completed all five telephone sessions. Treatment acceptability was high for both support persons and smokers. Compared with the control condition, the intervention was associated with a significant increase in support person self-efficacy to help their smoker (p = .034) and outcome expectancies (p = .025) from baseline to week 6. However, the intervention was not associated with higher smoking abstinence rates or quit attempts. DISCUSSION The program was successful in reaching smokers with lower levels of readiness to quit. The intervention was feasible and acceptable to both support persons and smokers. Although support persons and smokers can be engaged in this type of outreach program, refinements in the intervention approach are needed to improve the smoking outcomes.

Abstract
BACKGROUND Effective cessation services are greatly underutilized by smokers. Only about 1.5% of smokers in Minnesota utilize the state-funded QUITPLAN Helpline. Substantial evidence exists on the role of social support in smoking cessation. In preparation for a large randomized trial, this study developed and piloted an intervention for an adult nonsmoking support person to motivate and encourage a smoker to call the QUITPLAN Helpline. METHODS The support person intervention was developed based on Cohen's theory of social support. It consisted of written materials and three consecutive, weekly, 20-30 minute telephone sessions. Smoker calls to the QUITPLAN Helpline were documented by intake staff. RESULTS Participants were 30 support people (93% women, 97% Caucasian, mean age 49). High rates of treatment compliance were observed, with 28 (93%) completing all three telephone sessions. The intervention was ranked as somewhat or very helpful by 77% of the support people, and 97% would definitely or probably recommend the program. Five smokers linked to a support person called the QUITPLAN Helpline. CONCLUSIONS An intervention using natural support networks to promote smoker utilization of the QUITPLAN Helpline is both acceptable to a support person and feasible. A controlled randomized trial is under way to examine the efficacy of the intervention.
