Abstract
PURPOSE To describe the tobacco-related attitudes, behaviors, and needs of smoking and nonsmoking teens being seen for routine pediatric care and to identify predictors of tobacco use. DESIGN Cross-sectional survey of adolescent primary care patients who completed self-administered questionnaires in medical office waiting rooms while waiting for routine care visits. SETTING A group-practice HMO in the Pacific Northwest. SUBJECTS A sample of 2526 teenagers, ages 14 to 17, who consented to receive health promotion interventions as a part of a randomized trial in seven pediatric and family practice offices. MEASURES A 38-item questionnaire assessed tobacco use history, attitudes, quit attempts, and stage of acquisition or cessation along with gender, age, race/ethnicity, body mass index, educational plans, frequency of exercise, attempts to lose weight, and depressed mood. RESULTS Sixty-seven percent of teens approached (2526 of 3747) consented to complete a questionnaire and receive tobacco- or diet-related interventions as a part of their medical visit. About 23% of teen patients reported smoking at least one cigarette in the last month, although only 14% described themselves as current "smokers." Most current smokers (84%) smoked at least 20 days in the last month. Logistic regression predictors of smoking included older age, Native American ethnicity, lower educational aspirations, lower body mass index, smoking among half or more friends, smokers at home, and a positive depression screen. Among ever-regular smokers, most were in the action (28%), preparation (21%), or contemplation (22%) readiness to quit smoking stages, and 77% of current smokers had made one or more serious quit attempts in the last year. CONCLUSIONS Most teens in these medical facilities consented to receive tobacco and diet interventions, and most self-described current smokers were contemplating or preparing to quit. Medical visits provide attractive opportunities for tobacco intervention, but messages should be tailored based on the patient's tobacco status and stage of acquisition or cessation.

Abstract
BACKGROUND The disproportionate disease burden experienced by African-American women can be explained partially by the higher rates of obesity in this population. African-American women who can benefit from weight loss may be less likely to attempt it and may have relatively less success in using traditional weight loss programs compared to White women. Steps to Soulful Living (Steps) was a pilot study to test the effects of a culturally adapted weight loss program on weight loss in African-American women. METHODS Sixty-six African-American women participated in a 6-month weight loss program that included weekly group meetings and supervised exercise sessions. Mean baseline body mass index was 39 kg/m2, and mean baseline weight was 107 kg. Cultural adaptations, defined as program adjustments, made in response to women's preferences as expressed in focus group interviews included changes in intervention format, the content of the group meetings, and the location and format of the exercise sessions. RESULTS Seventy-six percent of the participants attended at least 50% of the 26 weekly sessions, and 56% attended at least 75% of the sessions. Average hours of exercise per week approximately doubled during the program in comparison to baseline levels. Mean weight loss at 26 weeks was 3.7 kg, categorizing those who were lost to follow-up as having zero weight loss. Participants who attended at least 75% of the group meetings lost a mean of 6.2 kg at six months. Those who attended fewer meetings lost a mean of 0.9 kg. CONCLUSIONS This 6-month program was associated with relatively larger weight losses, particularly among participants with high attendance, than have usually been observed in culturally adapted programs for African-American women.

Abstract
CONTEXT Although evidence-based national guidelines for tobacco-dependence treatment have been available since 1996, translating these guidelines into clinical practice is challenging. PRACTICE PATTERN EXAMINED Policies regarding tobacco-dependence treatment (e.g., written guidelines and coverage of pharmacotherapy) and implementation strategies of 11 U.S. managed care organizations known to have strong tobacco-control programs. DATA SOURCES Detailed telephone interviews with multiple informants at each health plan and review of written treatment guidelines and policies for tobacco dependence. RESULTS Although 10 of 11 plans had adopted tobacco-dependence treatment guidelines consistent with the national guideline, fewer had guidelines for special groups, such as adolescents (6 plans), parents (5 plans), pregnant women (5 plans), and hospitalized smokers (3 plans). Most plans offered clinician training and recommended office systems to support provider efforts; however, fewer actively facilitated their implementation. Most plans provided other support for tobacco treatment, including dedicated budgets, designated staff, and an oversight committee. All plans offered some coverage for tobacco-cessation pharmacotherapy and behavioral counseling, although not to the extent recommended by the national guideline. CONCLUSION Implementation of national tobacco-treatment guidelines is feasible in closed-panel managed care organizations. However, even these leading health plans could do more to comply with national practice guidelines on tobacco-dependence treatment and make it easier for clinicians to help patients stop smoking (e.g., through increased training and expanded coverage of tobacco-dependence treatment).

Abstract
This study examined whether a brief intervention to reduce hazardous alcohol consumption among primary care patients reduced use of medical care. In a parent, randomized controlled trial, at-risk drinkers identified in HMO outpatient waiting rooms were randomly assigned to receive usual care or brief clinician advice plus a 15-minute motivational counseling session. The current study (n = 514) examined the groups' use of outpatient and inpatient medical services during two years after intervention. Although the intervention reduced alcohol consumption at six-month follow-up, intervention and control groups made similar numbers of outpatient visits (M = 17.7 vs. 18.3, respectively; p = .47), were equally likely to be hospitalized (21.2% vs. 22.0%; p = .81), and among those hospitalized, had similar lengths of stay (4.7 vs. 6.6 days; p = .37). Although brief interventions to reduce hazardous drinking may potentially reduce medical care utilization, more evidence is needed to substantiate their practicality and cost-effectiveness.

Abstract
OBJECTIVES Previous research has documented that hospital-based smoking-cessation counseling is efficacious and cost-effective when delivered by research staff. This study evaluated the implementation and effectiveness of this intervention program when delivered by respiratory therapists chosen from the regular hospital staff. METHODS A total of 1,173 hospitalized smokers were randomly assigned to either usual care or a stage-based bedside counseling program supplemented with a videotape, self-help materials, and a follow-up telephone call. RESULTS Using an intent-to-treat analysis and counting those lost to follow-up as smokers, we did not find a significant difference in outcome between intervention (14.2% reported being abstinent for > or =6 months at the 1-year follow-up) and usual care conditions (13.6% abstinence). Process analyses revealed that these results were due to a combination of failure to reach many patients and reduced effectiveness of respiratory therapist interventionists compared with experienced professional counselors in a previous study conducted in the same hospitals. CONCLUSIONS We recommend implementation of hospital-based smoking-cessation counseling by professional counselors whose primary responsibility is to deliver the intervention. Recommendations for future research and for innovative ways to reach hospitalized smokers who are not receiving intervention are discussed.

Abstract
PURPOSE Stress Management Intervention (SMI) was one of seven nonpharmacologic approaches evaluated in Phase I Trials of Hypertension Prevention (TOHP-I) for efficacy in lowering diastolic blood pressure (BP) in healthy men and women aged 30 to 54 years with diastolic BP 80-89 mm Hg. METHODS A total of 242 and 320 participants were randomized to SMI or an "assessment only" SMI Control, respectively, at four clinical centers. The SMI consisted of 37 contact hours in 21 group and two individual meetings over 18 months and included: training in four relaxation methods, techniques to reduce stress reactions, cognitive approaches, communication skills, time management, and anger management within a general problem-solving format. Standardized protocols detailed methods and timing for collecting BP, psychosocial measures, and urinary samples from both SMI and SMI Control participants. RESULTS In intention-to-treat analyses, although significant baseline to termination BP reductions were observed in both groups, net differences between the SMI and SMI Control groups' BP changes (mean (95% CI)) were not significant: -0.82 (-1.86, 0.22) for diastolic BP, and -0.47 (-1.96, 1.01) for systolic BP. Extensive adherence sub-group analyses found one effect: a significant 1.36 mm Hg (p = 0.01) reduction in diastolic BP relative to SMI Controls at the end of the trial for SMI participants who completed 61% or more of intervention sessions. CONCLUSIONS While the TOHP-I SMI was acceptable to participants as evident from high levels of session completion, the absence of demonstrated BP lowering efficacy in intention-to-treat analyses suggests that the TOHP-I SMI is an unlikely candidate for primary prevention of hypertension in a general population sample similar to study participants. The isolated finding of significant diastolic BP lowering in SMI participants with higher adherence provides very weak evidence of SMI BP lowering efficacy and may be a chance finding. Whether similar or other stress management interventions can produce significant BP lowering in populations selected for higher levels of BP, stress, or intervention adherence remains to be demonstrated.

Abstract
This article reviews short-term (6 months) and longer term (12-24 months) maintenance of cessation and relapse in adult smokers and the factors and treatments that affect these outcomes. MedLine and PsycLIT searches were done for research published in English between 1988 and 1998 meeting a defined set of criteria. Intensive intervention, telephone counseling, and use of pharmacotherapy were found to improve outcomes; however, compared with public health approaches, they reach relatively few smokers. Brief interventions during medical visits are cost-effective and could potentially reach most smokers but are not consistently delivered. Predictors of relapse include slips, younger age, nicotine dependence, low self-efficacy, weight concerns, and previous quit attempts. Potential areas for research, recommendations for longer follow-up assessments, and standard definitions for slip, relapse, and long-term maintenance are discussed.

Abstract
CONTEXT It has been suggested that clinicians should increase efforts to modify and prevent risky behavior in adolescents. Professional organizations have proposed recommendations about access to care and preventive services, but it is difficult to know where and how to most effectively deliver such services. PRACTICE PATTERN EXAMINED Clinic visits among adolescent HMO members (14 to 17 years of age). SETTING Kaiser Permanente Northwest Division, a medium-sized, nonprofit, group-model HMO in the Pacific Northwest. DATA SOURCES Two administrative databases (one for membership and one for outpatient utilization). RESULTS A total of 22,626 adolescents who met the inclusion criteria were identified. Of these, 62% (more than 14,000 adolescents) were seen in a primary care clinic within 1 year; almost 83% (more than 18,000 adolescents) were seen within 2 years. There were several opportunities for follow-up for adolescents who had at least one visit in 1995: 60% had more than one visit during 1995, and 80% had more than one visit over the 2-year span of 1995 and 1996. The largest number of adolescent visits occurred in August through November, and most visits took place in the afternoon. CONCLUSIONS Primary care visits in an HMO present an excellent opportunity to reach many teenagers outside of a school setting. Short-term educational or prevention programs would be optimal during late summer and fall; additional staff members may be able to present these programs after school once school begins.

Abstract
OBJECTIVES This study evaluated the cost-effectiveness of a smoking cessation and relapse-prevention program for hospitalized adult smokers from the perspective of an implementing hospital. It is an economic analysis of a two-group, controlled clinical trial in two acute care hospitals owned by a large group-model health maintenance organization. The intervention included a 20-minute bedside counseling session with an experienced health counselor, a 12-minute video, self-help materials, and one or two follow-up calls. METHODS Outcome measures were incremental cost (above usual care) per quit attributable to the intervention and incremental cost per discounted life-year saved attributable to the intervention. RESULTS Cost of the research intervention was $159 per smoker, and incremental cost per incremental quit was $3,697. Incremental cost per incremental discounted life-year saved ranged between $1,691 and $7,444, much less than most other routine medical procedures. Replication scenarios suggest that, with realistic implementation assumptions, total intervention costs would decline significantly and incremental cost per incremental discounted life-year saved would be reduced by more than 90%, to approximately $380. CONCLUSIONS Providing brief smoking cessation advice to hospitalized smokers is relatively inexpensive, cost-effective, and should become a part of the standard of inpatient care.

Abstract
The American medical care system falls to provide effective prevention services even though some prevention services are among the most cost-effective medical procedures available. Many prevention services are routinely delivered in inefficient or ineffective ways, and new technologies may be widely and aggressively implemented despite serious doubts about their efficacy and cost-effectiveness. The barriers to effective prevention services result from conceptual limitations in our model of medical care systems, particularly the lack of a population-based perspective. A change in paradigm is needed before reforms in our health care system can improve health without bankrupting the nation.

Abstract
INTRODUCTION The study was designed to test a brief intervention for reducing alcohol consumption among moderate to heavy (hazardous) drinkers in a busy HMO primary care setting. METHODS In a randomized controlled trial, hazardous drinkers (n = 516) were identified by the AUDIT screening questionnaire. Intervention included brief clinician advice (30 seconds), a 15-minute motivational session by counselors, and printed materials. RESULTS At six-month follow-up, intervention subjects reported fewer total standard drinks in the past three months (176 versus 216, P = .04, one-tailed) and fewer drinking days per week (2.8 versus 3.3, P = .02) than controls, but similar drinks per drinking day (3.3 versus 3.5; P = .13). At 12 months, intervention subjects again reported fewer drinking days per week (2.7 versus 3.1; P = .04) than controls, but similar numbers of standard drinks (157 versus 179; P = .13) and drinks per drinking day (3.6 versus 3.3; P = .20). Intervention subjects were somewhat more likely than controls to report drinking within daily recommended limits (< or = 3 for men, < or = 2 for women) at both six months (79% versus 71%; P = .06) and 12 months (80% versus 73%; P = .07), but did not differ significantly from controls on other drinking outcomes (percent abstinent, frequency of drinking > or = 6 drinks per drinking occasion, estimated peak blood alcohol concentration), or use of medical care in the year following intervention. CONCLUSIONS A one-time, brief motivational intervention using minimal clinician time supplemented by trained counselors resulted in a modest reduction in frequency of alcohol consumption in a busy primary care population. Future research should focus on strengthening and maintaining intervention effects.

Abstract
INTRODUCTION Although recent reviews suggest few gender differences in smoking-cessation outcomes, it is important to establish whether gender differences exist in response to the brief interventions increasingly recommended as part of routine medical care. METHODS We used data from an efficacious primary care-based smoking intervention to examine gender differences in smoking characteristics, use of intervention components, self-reported quitting activities, and cessation outcomes among all smokers randomized to receive clinician advice and nurse-assisted intervention (n = 1,978, 58% female). RESULTS Although female and male smokers differed on a number of sociodemographic and smoking-related characteristics, they were equally likely to participate in each step of the recommended intervention. Female and male smokers were also equally likely to report quit attempts and cessation at 3, 12, and 3 and 12 months (combined long-term cessation endpoint). Similarly, no gender difference in relapse at 12 months was seen. Women attempting to quit used a greater number and variety of smoking-cessation strategies, suggesting that, although outcomes were similar, the processes of cessation may vary by gender. CONCLUSIONS Since this brief intervention in primary care was equally efficacious and acceptable to female and male smokers, broader implementation in medical settings of this population-based approach to reducing tobacco use is warranted. Indeed, widespread implementation of smoking-cessation programs in medical settings may particularly benefit women, who are more likely than men to have contacts with the medical care system.

Abstract
The purpose of this study was to evaluate the effects of a revised worksite health promotion program that featured an employee steering committee/menu approach to intervention. The "Take Heart II" program was evaluated using a quasi-experimental matched-pair design with worksite as the unit of analysis. Experimental and control worksites did not differ on baseline organizational or employee demographic variables or on baseline levels of dependent variables. Outcome and process results revealed consistent, but modest effects favoring intervention worksites on most measures. Cross-sectional analyses generally failed to produce statistically significant intervention effects, but cohort analyses revealed significant beneficial effects of the Take Heart II intervention on eating patterns, behavior change attempts, and perceived social support. Neither analysis detected a beneficial effect of intervention on cholesterol levels.

Abstract
A randomized clinical trial assessed the effect of a group-based behavior modification intervention on oral hygiene skills, adherence and clinical outcomes for older periodontal patients. Subjects (n = 107) were aged 50-70 yr with moderate periodontal disease. They were randomly assigned to usual care or intervention. Intervention consisted of 5 weekly, 90-min sessions that included skill training, self-monitoring, weekly feedback about bleeding points and group support focused on long-term habit change. Four-month follow-up indicated significant improvements in the intervention versus the usual periodontal maintenance group for oral hygiene skills and self-reported flossing (p < 0.001), plaque, gingival bleeding, bleeding upon probing throughout the mouth, and pocket depth for sulcus depths that measured between 3 and 6 mm at baseline (p < 0.009). Group oral health intervention provides an effective and relatively inexpensive means of helping patients improve their self-care skills and achieve high levels of adherence to an effective self-care regimen.

Abstract
Health care settings provide opportunities to reach populations of tobacco users with personalized cessation assistance. We describe a model for doing so which emphasizes a team approach, minimizes the burden on clinicians, and uses brief counseling by allied professionals, videos, written materials, and telephone calls to augment clinician advice. The model has been implemented in several diverse settings including outpatient, inpatient, and dental clinic managed care; fee-for-service dentistry and pediatric practices; and planned parenthood clinics. Data from several randomized trials support the effectiveness of the approach. The brief, low-intensity interventions derived from the model appear to be sustainable on a routine basis in many settings.

Abstract
Our research team is involved in ongoing research in both worksites and medical office settings. These settings offer great potential for reaching individuals who would not otherwise participate in health promotion, but they also place considerable constraints on assessment time and efforts, especially if one's goal is to attract a high and representative proportion of employees or patients. This paper reports on our experience with measures of dietary behavior in these two settings. We found it problematic to collect detailed assessments such as 4-day food records or comprehensive food frequency/history checklists in worksites or medical office settings using population-based samples. Instead, we recommend and provide data on the utility of a dietary-fat screening instrument, and on the Food Habits Questionnaire (FHQ-Kristal, Shattuck, & Henry, 1990), a brief measure of dietary behaviors associated with high-fat eating patterns. The FHQ, in particular, was found to correlate well with other more costly and time-consuming methods of assessment, to be reliable and responsive to intervention effects, and to provide behavioral targets for intervention. The strengths and limitations of these measures for tailoring intervention and assessing outcomes are discussed.

Abstract
Phase II of the Trials of Hypertension Prevention is a multicenter, randomized, controlled trial designed to determine the efficacy of weight loss and reduction of sodium intake for lowering blood pressure and incidence of hypertension among persons with high-normal levels of blood pressure. The 2 x 2 factorial study design includes weight loss alone, restricted sodium intake alone, the combination of weight loss and sodium restriction, and a control group. Nine clinical centers used a variety of recruitment strategies to enroll 2382 participants over 17 months, which exceeded the sample size goal of 2250. Among randomized participants, 21% were minorities and 34% were women. Overall, direct mail generated the most randomized participants (73%), followed by community screening (12%) and media advertisement (11%). Referrals from community health care providers yielded few participants. Prescreening improved overall efficiency and reduced costs. Participants who were more likely to drop out voluntarily during the three-visit screening regimen tended to be younger, single, male, smokers, and less educated.

Abstract
Phase II of the Trials of Hypertension Prevention (TOHP) is a multicenter, randomized trial sponsored by the National Heart, Lung, and Blood Institute designed to test whether weight loss alone, sodium reduction alone, or the combination of weight loss and sodium reduction will decrease diastolic (DBP) and systolic blood pressure (SBP) as well as the incidence of hypertension (DBP > or = 90 mm Hg, SBP > or = 140 mm Hg, and/or use of antihypertensive medications) in subjects with high-normal DBP (83 to 89 mm Hg) and SBP less than 140 mm Hg at entry. These interventions were chosen for longer-term testing with end points including hypertension prevention as well as blood pressure (BP) change based on their demonstrated short-term efficacy in reducing BP in phase I of TOHP. The phase II study population is comprised of 2382 participants (1566 men and 816 women) who are 110 to 165% of desirable body weight, allocated at random to the four treatment arms using a 2 x 2 factorial design. The trial has 80% power to detect an overall treatment effect on DBP of 1.2 mm Hg for weight loss or sodium reduction and a difference of 1.6 mm Hg between the combined intervention and placebo groups. BP observers are blinded to participant treatment assignments. Participants will be followed for 3 to 4 years. This trial may have important public policy implications concerning the ability of life-style modifications to reduce BP and prevent the development of hypertension over the long term, thereby avoiding the need for drug therapy which while effective is costly and may have side effects.

Abstract
OBJECTIVES The purpose of this study was to evaluate the short-term effects of a low-intensity work-site heart disease risk reduction program using a matched pair design with work site as the unit of analysis. METHODS Twenty-six heterogeneous work sites with between 125 and 750 employees were matched on key organization characteristics and then randomly assigned to early or delayed intervention conditions. Early intervention consisted of an 18-month multifaceted program that featured an employee steering committee and a menu approach to conducting key intervention activities tailored to each site. RESULTS Cross-sectional and cohort analyses produced consistent results. At the conclusion of the intervention, early and delayed intervention conditions did not differ on changes in smoking rates, dietary intake, or cholesterol levels. There was considerable variability in outcomes among work sites within each condition. CONCLUSIONS Despite documented implementation of key intervention activities and organization-level changes in terms of perceived support for health promotion, this intervention did not produce short-term improvements beyond secular trends observed in control work sites. Research is needed to understand determinants of variability between work sites.

Abstract
This article describes the conceptual basis, design, and intervention approach for a worksite-based heart disease risk reduction project. Baseline characteristics of the 26 moderate size worksites participating in the Take Heart Project are also described. The trial is designed to produce changes at both the organization and employee level on tobacco use, dietary fat intake, and serum cholesterol. A key feature of the intervention is creation of employee steering committees to enhance ownership and involvement. From a menu of brief, low-intensity health education and environmental change activities, these committees select activities best suited to their worksite. The baseline characteristics of organizations randomized to intervention and control conditions were similar, and indicated a relatively high level of worksite activity related to cholesterol and smoking.

Abstract
A randomized trial of falls prevention program that addressed home safety, exercise, and behavioral risks was conducted with 3,182 independently living HMO members age 65 and older. The intervention decreased the odds of falling by 0.85, but only reduced the average number of falls among those who fell by 7%. The effect was strongest among men age 75 and older. The likelihood of avoiding falls requiring medical treatment was not significantly affected by the intervention. We conclude that the intervention dose was not of sufficient intensity or duration to have a marked protective effect on older persons. Future research should focus on more intensive intervention approaches because serious falls do not appear to be amendable to low-intensity environment/behavioral efforts.

Abstract
Biochemical validation of smoking status has long been considered essential, but recent reports have questioned its utility in certain kinds of field trials. We describe efforts to biochemically validate self-reports of smoking cessation from participants in four large-scale randomized trials in outpatient clinics, hospitals, worksites, and dental clinics. These studies included over 5,000 adults smokers who participated in the population-based low-intensity intervention evaluations. At a 1-year follow-up, 798 subjects reported no tobacco use. We attempted to verify these reports using saliva continine/carbon monoxide validation procedures. Overall, there was a moderately high nonparticipation rate (27%), a low disconfirmation rate (4%), and a high self-reported relapse rate (12%) in the interval between survey and biochemical validation. There were no differences between intervention and control conditions on any of the above variables. Longer durations of self-reported abstinence were strongly related to increased probability of biochemical confirmation. Differences in results across projects were related to how biochemical validation was conducted. These results, as well as statistical power considerations, raise questions about whether biochemical validation procedures are practical, informative, or cost-effective in such population-based, low-intensity intervention research.

Abstract
This study evaluated the impact of a year-long incentives-based worksite smoking-cessation program. Nineteen moderate-sized worksites, employing a total of approximately 1100 smokers, were randomized to Incentive or No Incentive conditions. All identified smokers in the worksite were considered as subjects, whether or not they participated in the intervention. Analyses were conducted at both the worksite and individual level, and using both self-reported and biochemically validated cessation as endpoints. The incentive program did not significantly improve cessation rates at either the 1-year or 2-year follow-up assessments. We conclude that more broadly focused interventions that also address worksite smoking policies, skills training, and cessation resources, or programs that target additional risk factors are needed to substantially enhance quit rates.

Abstract
OBJECTIVE Physician-delivered advice to stop smoking is effective, but time demands often reduce the number of smokers who receive assistance. We evaluated three nurse-assisted interventions designed to minimize physician burden and increase counseling in primary care settings. DESIGN Randomized controlled trial with a 12-month follow-up. SETTING Internal medicine and family practice offices in a health maintenance organization. PARTICIPANTS Smokers (n = 3161) who were patients of participating physicians or other medical care providers (n = 60). INTERVENTION Medical care providers delivered a 30-second stop-smoking prompt to 2707 smokers and referred them to an on-site nurse smoking counselor. The nurse randomly provided a two-page pamphlet (advice control) or one of three nurse-assisted interventions: 1) self-quit training; 2) referral to a group cessation program; or 3) a combination of self-quit training and referral. Each nurse-delivered intervention included a 10-minute video, written materials, and a follow-up phone call. RESULTS Physicians delivered brief advice to 86% of identified smokers during the 1-year program. The proportion of participants reporting abstinence after both 3 and 12 months of follow-up nearly doubled (P = 0.01) for the nurse-assisted self-quit (7.1%), group-referral (7.6%), and combination (6.9%) interventions, compared to brief physician advice alone (3.9%) (P < 0.05). Saliva cotinine tests confirmed these effects (P < 0.004), although quit rates were lower (3.4%, 4.7%, 4.3%, and 2.3%, respectively) because roughly one half of quitters chose not to provide a saliva sample and were counted as smokers. CONCLUSION Involving nurses in counseling smokers reduces physician burden, makes counseling more likely, and significantly increases cessation rates compared with brief physician advice alone.
