Brief advice to stop smoking from general practitioners (GPs) has been repeatedly shown to increase smoking cessation by a small, but measurable amount. Some studies have suggested that adding more intensive interventions to brief advice may increase its effectiveness, but it is unclear whether this is true in general practice.
                To determine whether brief advice from a doctor together with counselling and follow-up from a trained practice nurse is more effective than brief advice alone in helping people to stop smoking.
                The design was a randomized controlled trial. Four hundred and ninety-seven general practice patients aged older than 18 years and smoking at least one cigarette per day in six general practices in Oxfordshire, Berkshire, and Buckinghamshire were randomized to one of two interventions: brief verbal or written advice from a GP plus extended counselling and follow-up from a trained practice nurse; brief advice from a GP alone. The primary outcome was sustained abstinence from smoking at three and 12 months. A secondary outcome was forward movement in the stages of change cycle.
                The proportion showing sustained abstinence was 3.6% in the extended counselling group, and 4.4% in the brief advice group (difference = -0.8%; 95% confidence interval = -4.3% to 2.6%). Seventy-four (30%) of those randomized to extended counselling actually took up this offer. No significant progression in stages of change was detected between the two groups.
                In unselected general practice patients who smoke, brief advice from a GP combined with intensive intervention and follow-up by a practice nurse is no more effective than brief advice alone. To test the efficacy of (i) computer-generated tailored letters and (ii) practitioner-delivered brief advice for smoking cessation against an assessment-only condition; and to compare both interventions directly.
                Quasi-randomized controlled trial.
                A total of 34 randomly selected general practices from a German region (participation rate 87%).
                A total of 1499 consecutive patients aged 18-70 years with daily cigarette smoking (participation rate 80%).
                The tailored letters intervention group received up to three individualized personal letters. Brief advice was delivered during routine consultation by the practitioner after an onsite training session. Both interventions were based on the Transtheoretical Model of behaviour change.
                Self-reported point prevalence and prolonged abstinence at 6-, 12-, 18- and 24-month follow-ups.
                Among participants completing the last follow-up, 6-month prolonged abstinence was 18.3% in the tailored letters intervention group, 14.8% in the brief advice intervention group and 10.5% in the assessment-only control group. Assuming those lost to follow-up to be smokers, the rates were 10.2%, 9.7% and 6.7%, respectively. Analyses including all follow-ups confirmed statistically significant effects of both interventions compared to assessment only. Using complete case analysis, the tailored letters intervention was significantly more effective than brief advice for 24-hour [odds ratio (OR) = 1.4; P = 0.047] but not for 7-day point prevalence abstinence (OR = 1.4; P = 0.068) for prolonged abstinence, or for alternative assumptions about participants lost to follow-up.
                The study demonstrated long-term efficacy of low-cost interventions for smoking cessation in general practice. The interventions are suitable to reach entire populations of general practices and smoking patients. Computer-generated letters are a promising option to overcome barriers to provide smoking cessation counselling routinely. The primary care visit represents an important venue for intervening with a large population of smokers. However, physician adherence to the Smoking Cessation Clinical Guideline (5As) remains low. We evaluated the effectiveness of a computer-tailored intervention designed to increase smoking cessation counseling by primary care physicians.
                Physicians and their patients were randomized to either intervention or control conditions. In addition to brief smoking cessation training, intervention physicians and patients received a one-page report that characterized the patients' smoking habit and history and offered tailored recommendations. Physician performance of the 5As was assessed via patient exit interviews. Quit rates and smoking behaviors were assessed 6 months postintervention via patient phone interviews. Intervention effects were tested in a sample of 70 physicians and 518 of their patients. Results were analyzed via generalized and mixed linear modeling controlling for clustering.
                Intervention physicians exceeded controls on "Assess" (OR 5.06; 95% CI 3.22, 7.95), "Advise" (OR 2.79; 95% CI 1.70, 4.59), "Assist-set goals" (OR 4.31; 95% CI 2.59, 7.16), "Assist-provide written materials" (OR 5.14; 95% CI 2.60, 10.14), "Assist-provide referral" (OR 6.48; 95% CI 3.11, 13.49), "Assist-discuss medication" (OR 4.72;95% CI 2.90, 7.68), and "Arrange" (OR 8.14; 95% CI 3.98, 16.68), all p values being < 0.0001. Intervention patients were 1.77 (CI 0.94, 3.34,p = 0.078) times more likely than controls to be abstinent (12 versus 8%), a difference that approached, but did not reach statistical significance, and surpassed controls on number of days quit (18.4 versus 12.2, p < .05) but not on number of quit attempts.
                The use of a brief computer-tailored report improved physicians' implementation of the 5As and had a modest effect on patients' smoking behaviors 6 months postintervention. To evaluate the effectiveness of individually tailored smoking cessation advice letters as an adjunct to telephone counselling and generic self-help materials.
                Randomized controlled trial.
                The UK Quitline.
                A total of 1508 current smokers and recent ex-smokers.
                The control group received usual care (telephone counselling and an information pack sent through the post). The intervention group received in addition a computer-generated individually tailored advice letter.
                All outcomes were assessed at 6-month follow-up. The primary outcome measure was self-reported prolonged abstinence for at least 3 months. Secondary outcomes were self-reported prolonged abstinence for at least 1 month and 7-day and 24-hour point-prevalence abstinence.
                For the sample as a whole, quit rates did not differ significantly between the two conditions. However, among the majority (n = 1164) who were smokers at baseline, quit rates were consistently higher in the intervention group: prolonged abstinence for 3 months, 12.2% versus 9.0% [odds ratio (OR) = 1.40, 95% confidence interval (CI) = 0.96-2.04, P = 0.080); prolonged abstinence for 1 month, 16.4% versus 11.3% (OR = 1.53, 95% CI = 1.09-2.15, P = 0.013); 7-day point-prevalence abstinence, 18.9% versus 12.7% (OR = 1.59, 95% CI = 1.15-2.19, P = 0.004); 24-hour point-prevalence abstinence, 20.9% versus 15.4% (OR = 1.45, 95% CI = 1.07-1.96, P = 0.015).
                The results for the smokers are encouraging in showing a small but useful effect of the tailored letter on quit rate. Versions of the tailoring program could be used on the web and in general practices, pharmacies and primary care trusts. 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.
                Randomized controlled trial with a 12-month follow-up.
                Internal medicine and family practice offices in a health maintenance organization.
                Smokers (n = 3161) who were patients of participating physicians or other medical care providers (n = 60).
                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.
                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.
                Involving nurses in counseling smokers reduces physician burden, makes counseling more likely, and significantly increases cessation rates compared with brief physician advice alone. Few studies have rigorously evaluated whether providing biologically based health-risk feedback is more effective than standard interventions in increasing smokers' motivation to quit and their long-term abstinence.
                An RCT was conducted from 2005 to 2008. Data were analyzed in 2008.
                Smokers (N=536) were recruited from the community, regardless of their interest in quitting smoking.
                Smokers either received brief ( approximately 20 minutes), personally tailored counseling sessions based on their lung functioning, carbon monoxide (CO) exposure, and smoking-related health conditions, or they received generic smoking-risk information and personalized counseling about their diet, BMI, and physical activity. All were advised to quit smoking and were offered access to a free phone-counseling program.
                Treatment utilization and abstinence at 6 and 12 months post-intervention.
                Participants who received the experimental treatment demonstrated no greater motivation to quit, use of treatment services, or abstinence compared to controls at either follow-up assessment. In fact, controls reported greater motivation to quit at 12 months (M 3.42 vs 3.20, p=0.03), greater use of pharmacotherapy at 6 months (37.8% vs 28.0%, p=0.02), and greater 30-day point prevalent abstinence at 6 months, after controlling for relevant covariates (10.8% vs 6.4%, adjusted p=0.04).
                The present study found no support for adding a personalized health-risk assessment emphasizing lung health and CO exposure to generic cessation advice and counseling for community-based smokers not otherwise seeking treatment.
                NCT00169260. To determine the effect of adding biomarker feedback (expired air carbon monoxide) to standard quit advice on cognitive antecedents of behavior change and smoking cessation and to identify potential effect moderators and mediators.
                Smokers (N = 160) were randomized to a control (quit advice plus leaflet) or an intervention condition (as control group plus carbon-monoxide level feedback). Cognitive measures were assessed immediately after the intervention and behavioral measures at 6 months' follow-up.
                Primary outcome measures were threat and efficacy appraisal, fear arousal, and intention to stop smoking. Secondary outcome measures were quit attempts within the last 6 months and 7-day point prevalence abstinence.
                Threat appraisal was significantly enhanced in the intervention compared with the control group, t(158) = 2.29, p = .023, as was intention to stop smoking in the next month, t(151) = 2.9, p = .004. However, this effect on intention to stop smoking was short-lived. Groups did not differ in terms of quit attempts or abstinence at follow-up, but the intervention increased the likelihood of cessation in smokers with higher self-efficacy, χ2(1) = 5.82, p = .016.
                Carbon-monoxide level feedback enhances the effect of brief quit advice on cognitive antecedents of behavior change and smoking cessation rates but further research is required to confirm the longevity of this effect and its applicability to smokers with low self-efficacy.
                (PsycINFO Database Record (c) 2010 APA, all rights reserved). This study evaluated the effects of including a single brief prequit telephone counseling session in a self-help program for smoking cessation conducted through the mail, by comparison with the effects of the self-help program alone. Volunteer participants from northwestern Spain (N = 228) were randomly assigned to one of two groups: (a) the self-help-only group (n = 110, mean age = 37.4 years, pretreatment cigarette consumption = 26.5 cigarettes/day) or (b) the telephone-support group (n = 118, mean age = 36.8 years, pretreatment cigarette consumption = 27.7 cigarettes/day). Using a conservative data analysis method (missing data considered as treatment failures), we found that the point-prevalence abstinence rate was significantly higher in the telephone-support group than in the self-help-only group at the end of treatment (44.9% vs. 21.8%) and at the 3-month follow-up (39.0% vs. 26.4%). Likewise, sustained abstinence was significantly higher in the telephone-support group at the 3-month follow-up (33.9% vs. 13.6%), the 6-month follow-up (25.4% vs. 12.7%), and the 12-month follow-up (21.2% vs. 9.1%). The results of this randomized controlled trial indicate that both treatments are an effective aid for smoking cessation, and that a single brief telephone call before the quit date is a low-cost and effective procedure for improving abstinence rates in a mailed self-help program. The purpose of this study was to evaluate a brief smoking cessation intervention for women 15 to 35 years of age attending Planned Parenthood clinics.
                Female smokers (n = 1154) were randomly assigned either to advice only or to a brief intervention that involved a 9-minute video, 12 to 15 minutes of behavioral counseling, clinician advice to quit, and follow-up telephone calls.
                Seventy-six percent of those eligible participated. Results revealed a clear, short-term intervention effect at the 6-week follow-up (7-day self-reported abstinence: 10.2% vs 6.9% for advice only, P < .05) and a more ambiguous effect at 6 months (30-day biochemically validated abstinence: 6.4% vs 3.8%, NS).
                This brief, clinic-based intervention appears to be effective in reaching and enhancing cessation among female smokers, a traditionally underserved population.
Simple advice has a small effect on cessation rates. Assuming an unassisted quit rate of 2 to 3%, a brief advice intervention can increase quitting by a further 1 to 3%. Additional components appear to have only a small effect, though there is a small additional benefit of more intensive interventions compared to very brief interventions.
