Physician advice for smoking cessation

Management of Crohn's disease in smokers: is an alternative approach necessary?

Inflammatory bowel disease is a chronic condition with a pathogenic background that involves both genetic and environmental factors. Although important progress has been made regarding the former in the last decade, scarce knowledge is available for the latter. In this sense, smoking remains the most important environmental factor in IBD. Active smoking increases the risk of developing Crohn's disease (CD). Moreover, CD patients who start or continue smoking after disease diagnosis are at risk for poorer outcomes such as higher therapeutic requirements and disease-related complications, as compared to those patients who quit smoking or who never smoked. However, the harmful effect of active smoking is not uniform in all patients or in all clinical scenarios. Interventions designed to facilitate smoking cessation may impact the course of the disease. In this article, the available evidence of the deleterious effects of smoking on CD is reviewed in detail, and alternative therapeutic approaches to CD in smokers are proposed.

Prospective predictors of quitting behaviours among adult smokers in six cities in China: findings from the International Tobacco Control (ITC) China Survey

AIMS

To examine predictors of quitting behaviours among adult smokers in China, in light of existing knowledge from previous research in four western countries and two southeast Asian countries.

DESIGN

Face-to-face interviews were carried out with smokers in 2006 using the International Tobacco Control (ITC) China Survey, with follow-up about 16 months later. A stratified multi-stage cluster sampling design was employed.

SETTING

Beijing and five other cities in China.

PARTICIPANTS

A total of 4732 smokers were first surveyed in 2006. Of these, 3863 were re-contacted in 2007, with a retention rate of 81.6%.

MEASUREMENTS

Baseline measures of socio-demographics, dependence and interest in quitting were used prospectively to predict both making quit attempts and staying quit among those who attempted.

FINDINGS

Overall, 25.3% Chinese smokers reported having made at least one quit attempt between waves 1 and 2; of these, 21.7% were still stopped at wave 2. Independent predictors of making quit attempts included having higher quitting self-efficacy, previous quit attempts, more immediate intentions to quit, longer time to first cigarette upon waking, negative opinion of smoking and having smoking restrictions at home. Independent predictors of staying quit were being older, having longer previous abstinence from smoking and having more immediate quitting intentions.

CONCLUSIONS

Predictors of Chinese smokers' quitting behaviours are somewhat different to those found in previous research from other countries. Nicotine dependence and self-efficacy seem to be more important for attempts than for staying quit in China, and quitting intentions are related to both attempts and staying quit.

Effective implementation of research into practice: an overview of systematic reviews of the health literature

BACKGROUND

The gap between research findings and clinical practice is well documented and a range of interventions has been developed to increase the implementation of research into clinical practice.

FINDINGS

A review of systematic reviews of the effectiveness of interventions designed to increase the use of research in clinical practice. A search for relevant systematic reviews was conducted of Medline and the Cochrane Database of Reviews 1998-2009. 13 systematic reviews containing 313 primary studies were included. Four strategy types are identified: audit and feedback; computerised decision support; opinion leaders; and multifaceted interventions. Nine of the reviews reported on multifaceted interventions. This review highlights the small effects of single interventions such as audit and feedback, computerised decision support and opinion leaders. Systematic reviews of multifaceted interventions claim an improvement in effectiveness over single interventions, with effect sizes ranging from small to moderate. This review found that a number of published systematic reviews fail to state whether the recommended practice change is based on the best available research evidence.

CONCLUSIONS

This overview of systematic reviews updates the body of knowledge relating to the effectiveness of key mechanisms for improving clinical practice and service development. Multifaceted interventions are more likely to improve practice than single interventions such as audit and feedback. This review identified a small literature focusing explicitly on getting research evidence into clinical practice. It emphasizes the importance of ensuring that primary studies and systematic reviews are precise about the extent to which the reported interventions focus on changing practice based on research evidence (as opposed to other information codified in guidelines and education materials).

Physician communication regarding smoking and adolescent tobacco use

BACKGROUND

Physician advice increases quit rates 1% to 3% above unassisted quit rates among adults, an increase sufficient to be ranked as a high-priority, evidence-based preventive service. However, there is little research on the potential impact of physician advice on adolescent smoking.

OBJECTIVE

The purpose of this study was to examine the association between recalled physician communication and adolescents' attitudes toward smoking, knowledge about smoking, intentions to smoke, tobacco use, and quitting behaviors.

METHODS

This study was a retrospective observational study of 5154 students (82.9% black, 17.1% white) from an urban, mid-South school system. Outcome variables included adolescents' self-rated attitudes toward smoking, knowledge about smoking, intentions to smoke, tobacco use, and quitting behaviors.

RESULTS

Physician advice and the combination of screening and advice were associated with healthier attitudes about smoking. Physician screening and advice were also associated with a more accurate knowledge regarding tobacco-related damage. Among current smokers, recalled physician advice was also associated with reduced intentions to smoke in 5 years. Importantly, advised teens were more likely to plan to quit smoking in 6 months. Furthermore, teens who were screened by their physician reported significantly more quit attempts than those who were neither screened nor advised (P = .007).

CONCLUSIONS

Physician's tobacco-related interactions with adolescents seemed to positively impact their attitudes, knowledge, intentions to smoke, and quitting behaviors. Brief physician interventions have the potential to be a key intervention on a public health level through the prevention, cessation, and reduction of smoking and smoking-related disease.

How to promote healthy behaviours in patients? An overview of evidence for behaviour change techniques

To identify the evidence for the effectiveness of behaviour change techniques, when used by health-care professionals, in accomplishing health-promoting behaviours in patients. Reviews were used to extract data at a study level. A taxonomy was used to classify behaviour change techniques. We included 23 systematic reviews: 14 on smoking cessation, 6 on physical exercise, and 2 on healthy diets and 1 on both exercise and diets. None of the behaviour change techniques demonstrated clear effects in a convincing majority of the studies in which they were evaluated. Techniques targeting knowledge (n = 210 studies) and facilitation of behaviour (n = 172) were evaluated most frequently. However, self-monitoring of behaviour (positive effects in 56% of the studies), risk communication (52%) and use of social support (50%) were most often identified as effective. Insufficient insight into appropriateness of technique choice and quality of technique delivery hinder precise conclusions. Relatively, however, self-monitoring of behaviour, risk communication and use of social support are most effective. Health professionals should avoid thinking that providing knowledge, materials and professional support will be sufficient for patients to accomplish change and consider alternative strategies which may be more effective.

[Guidelines for smoking cessation - update 2010]

In 2005, the ÖGP (Austrian Society of Pneumology) worked out the first standards of smoking cessation. With many new therapies, it is timely to update the guidelines of smoking cessation. This time all relevant professionals who are active in smoking cessation in Austria worked together in a big consensus process, not only the diverse medical professionals such as internists, pneumologists, or gynecologists but also psychotherapists, psychologists, and nurses. The Austrian standards for smoking cessation is closely related to the Update for smoking cessation 2008 of the USDHHS (US Department of Health and Human Services) and the Cochrane Reports. Ten main recommendations for smoking cessation have been worked out. The guidelines for smoking cessation was reviewed by three international reviewers.

A comparison of patient recall of smoking cessation advice with advice recorded in electronic medical records

Background

Brief cessation advice delivered to smokers during routine primary care consultations increases smoking cessation rates. However, in previous studies investigating recall of smoking cessation advice, smokers have reported more advice being received than is actually documented in their medical records. Recording of smoking cessation advice in UK primary care medical records has increased since the introduction of the Quality and Outcomes Framework (QOF) in 2004, and so we compare recall and recording of cessation advice since this time to assess whether or not agreement between these two data sources has improved.

Methods

For each year from 2000 to 2009, the proportion of patients in The Health Improvement Network Database (THIN) with a recording of cessation advice in their notes in the last 12 months was calculated. In 2004, 2005 and 2008, these figures were compared to rates of patients recalling having received cessation advice in the last 12 months in the Primary Care Trust (PCT) Patient Surveys, with adjustment for age, sex and regional differences between the populations.

Results

In 2004 there was good agreement between the proportion of THIN patients who had cessation advice recorded in their medical records and the proportion recalling advice in the Patient Survey. However, in both 2005 and 2008, more patients had cessation advice recorded in their medical records than recalled receiving advice.

Conclusions

Since the introduction of the QOF, the rate of recording of cessation advice in primary care medical records has exceeded that of patient recall. Whilst both data sources have limitations, our study suggests that, in recent years, the proportion of smokers being advised to quit by primary care health professionals may not have improved as much as the improved recording rates imply.

Behavior matters

Behavior has a broad and central role in health. Behavioral interventions can be effectively used to prevent disease, improve management of existing disease, increase quality of life, and reduce healthcare costs. A summary is presented of evidence for these conclusions in cardiovascular disease/diabetes, cancer, and HIV/AIDS as well as with key risk factors: tobacco use, poor diet, physical inactivity, and excessive alcohol consumption. For each, documentation is made of (1) moderation of genetic and other fundamental biological influences by behaviors and social-environmental factors; (2) impacts of behaviors on health; (3) success of behavioral interventions in prevention; (4) disease management; (5) quality of life, and (6) improvements in the health of populations through behavioral health promotion programs. Evidence indicates the cost effectiveness and value of behavioral interventions, especially relative to other common health services as well as the value they add in terms of quality of life. Pertinent to clinicians and their patients as well as to health policy and population health, the benefits of behavioral interventions extend beyond impacts on a particular disease or risk factor. Rather, they include broad effects and benefits on prevention, disease management, and well-being across the life span. Among priorities for dissemination research, the application of behavioral approaches is challenged by diverse barriers, including socioeconomic barriers linked to health disparities. However, behavioral approaches including those emphasizing community and social influences appear to be useful in addressing such challenges. In sum, behavioral approaches should have a central place in prevention and health care of the 21st century.

Pharmacotherapy for smoking cessation: current advances and research topics

Promoting smoking cessation is among the key medical interventions aimed at reducing worldwide morbidity and mortality in this century. Both behavioural counselling and pharmacotherapy have been shown to significantly increase long-term abstinence rates, and combining the two treatment modalities is recommended. This article provides an update on pharmacotherapy for smoking cessation in the general population. Current first-line agents used to support quit attempts are nicotine replacement therapy (NRT), bupropion and varenicline. Research suggests that abstinence rates can be increased by combining different forms of NRT or simultaneously administering NRT and non-nicotine medications. New treatments targeting the nicotinic acetylcholine receptor as well as other pathophysiological pathways involved in nicotine addiction are being developed, with nicotine vaccines now being tested in phase III clinical trials. Among the numerous research topics currently addressed, pharmacogenetics and tailoring therapy to specific groups of smokers look most promising. However, substantial progress is unlikely to be made unless social gradients impeding effective treatment of all smokers are overcome. In addition, public smoking bans and reimbursement of medication costs are crucial in reducing the future burden of disease caused by smoking on a global level.

Applying the Theory of Planned Behavior to Explore the Relation Between Smoke-Free Air Laws and Quitting Intentions

Smoke-free air policies have been shown to reduce smoking, but the mechanism of behavior change is not well understood. The authors used structural equation modeling to conduct a theory of planned behavior analysis with data from 395 smokers living in seven Texas cities, three with a comprehensive smoke-free air law and four without a comprehensive law. Agreement with regulating smoking in public places was significantly associated with attitudes and perceived normative pressure about quitting. Nicotine dependence was significantly associated with attitudes and perceived behavioral control. There was also a direct effect of nicotine dependence on intention to take measures to quit smoking. Smoke-free air laws appear to influence quitting intentions through the formation of positive attitudes about regulating smoking in public places and the perception of normative pressure to take measures to quit. Implications for smoke-free air policy campaigns and challenges in evaluating their effectiveness are discussed.

General practice counseling for patients with chronic obstructive pulmonary disease to quit smoking: impact after 1 year of two complex interventions

OBJECTIVE

To evaluate two counseling programs in general practice to help smokers with chronic obstructive pulmonary disease (COPD) to quit smoking.

METHODS

Cluster randomized controlled trial including 68 general practices (667 patients) using a randomly assigned intervention program with counseling and advice about nicotine replacement therapy (and additional bupropion-SR in one of the programs) or usual care. Usual care consisted of periodic regular check-ups and COPD information. The main outcome measure was biochemically verified point prevalence at 12 months.

RESULTS

The two intervention groups were treated as one in the analysis because they were equally effective. The intervention resulted in a significantly self-reported higher success rate (14.5%) compared to usual care (7.4%); odds ratio=2.1, 95% confidence interval=1.1-4.1. Biochemically verified quit rates were 7.5% (intervention) and 3.4% (usual care); odds ratio=2.3, 95% confidence interval=0.9-6.0.

CONCLUSION

The program doubled the cessation rates (statistically nonsignificant). Too few participants used the additional bupropion-SR to prove its effectiveness.

PRACTICE IMPLICATIONS

The protocols can be used for COPD patients in general practice, but expectations should be modest. If quitting is unsuccessful, a stepped care approach should be considered.

Smoking cessation in indigenous populations of Australia, New Zealand, Canada, and the United States: elements of effective interventions

Indigenous people throughout the world suffer a higher burden of disease than their non-indigenous counterparts contributing to disproportionate rates of disability. A significant proportion of this disability can be attributed to the adverse effects of smoking. In this paper, we aimed to identify and discuss the key elements of individual-level smoking cessation interventions in indigenous people worldwide. An integrative review of published peer-reviewed literature was conducted. Literature on smoking cessation interventions in indigenous people was identified via search of electronic databases. Documents were selected for review if they were published in a peer-reviewed journal, written in English, published from 1990-2010, and documented an individual-level intervention to assist indigenous people to quit smoking. Studies that met inclusion criteria were limited to Australia, New Zealand, Canada, and the USA, despite seeking representation from other indigenous populations. Few interventions tailored for indigenous populations were identified and the level of detail included in evaluation reports was variable. Features associated with successful interventions were integrated, flexible, community-based approaches that addressed known barriers and facilitators to quitting smoking. More tailored and targeted approaches to smoking cessation interventions for indigenous populations are required. The complexity of achieving smoking cessation is underscored as is the need to collaboratively develop interventions that are acceptable and appropriate to local populations.

Chronic diseases and injuries in India

Chronic diseases (eg, cardiovascular diseases, mental health disorders, diabetes, and cancer) and injuries are the leading causes of death and disability in India, and we project pronounced increases in their contribution to the burden of disease during the next 25 years. Most chronic diseases are equally prevalent in poor and rural populations and often occur together. Although a wide range of cost-effective primary and secondary prevention strategies are available, their coverage is generally low, especially in poor and rural populations. Much of the care for chronic diseases and injuries is provided in the private sector and can be very expensive. Sufficient evidence exists to warrant immediate action to scale up interventions for chronic diseases and injuries through private and public sectors; improved public health and primary health-care systems are essential for the implementation of cost-effective interventions. We strongly advocate the need to strengthen social and policy frameworks to enable the implementation of interventions such as taxation on bidis (small hand-rolled cigarettes), smokeless tobacco, and locally brewed alcohols. We also advocate the integration of national programmes for various chronic diseases and injuries with one another and with national health agendas. India has already passed the early stages of a chronic disease and injury epidemic; in view of the implications for future disease burden and the demographic transition that is in progress in India, the rate at which effective prevention and control is implemented should be substantially increased. The emerging agenda of chronic diseases and injuries should be a political priority and central to national consciousness, if universal health care is to be achieved.

Validation of smoking cessation self-reported by patients with chronic obstructive pulmonary disease

PURPOSE

The present study reports on the biochemical validation of the self-reported smoking status of patients with chronic obstructive pulmonary disease (COPD). The objective is to establish the proportion of overestimation of self-reported success rates.

METHODS

A cross-sectional smoking-status validation study including 60 patients with COPD who reported that they had stopped smoking. In the analysis of urine samples, a cut-off point of 50 ng/mL of cotinine was used.

RESULTS

At the time of biochemical validation, 55 patients reported that they had quit smoking while five patients resumed smoking. Smoking status was biochemically confirmed for 43 patients (78%) and 12 patients (22%) were classified as smokers. The sensitivity of the self- report of smoking was 29% and the specificity was 100%.

CONCLUSION

Many primary care patients with COPD do not provide valid information on their smoking status, which hamper adequate therapeutic interventions. Integration of biochemical validation in daily care could overcome this problem, but may harm the doctor-patient relationship.

Quitting smoking in China: findings from the ITC China Survey

Background

Few studies have examined interest in quitting smoking and factors associated with quitting in mainland China.

Objective

To characterise interest in quitting, quitting behaviour, the use of cessation methods and reasons for thinking about quitting among adult urban smokers in six cities in China.

Methods

Data is from Wave 1 of the ITC China Survey, a face-to-face household survey of 4732 adult smokers randomly selected from six cities in China in 2006. Households were sampled using a stratified multistage design.

Findings

The majority of smokers had no plan to quit smoking (75.6%). Over half (52.7%) of respondents had ever tried to quit smoking. Few respondents thought that they could successfully quit smoking (26.5%). Smokers were aware of stop-smoking medications (73.5%) but few had used these medications (5.6%). Only 48.2% had received advice from a physician to quit smoking. The number one reason for thinking about quitting smoking in the last 6 months was concern for personal health (55.0%). Most smokers also believed that the government should do more to control smoking (75.2%).

Conclusion

These findings demonstrate the need to: (1) increase awareness of the dangers of smoking; (2) provide cessation support for smokers; (3) have physicians encourage smokers to quit; (4) denormalise tobacco use so that smokers feel pressured to quit; (5) implement smoke-free laws to encourage quitting; (6) develop stronger warning labels about the specific dangers of smoking and provide resources for obtaining further cessation assistance; and (7) increase taxes and raise the price of cigarettes.

Smoking cessation advice in consultations with health problems not related to smoking? Relevance criteria in Danish general practice consultations

OBJECTIVE

To identify frames of interaction that allow smoking cessation advice in general practice consultations.

DESIGN

Qualitative study based on individual in-depth interviews with GPs and their patients. Each of the GPs' consultations were observed during a three-day period. Interviews primarily addressed the consultations that had been observed. The concept of "frames" described by Goffman was deployed as an analytic tool.

SETTING

Danish general practice.

SUBJECTS

Six GPs and 11 of their patients.

RESULTS

Both GPs and patients evaluated potential issues to be included during consultations by relevance criteria. Relevance criteria served the purpose of limiting the number of issues in individual consultations. Issues could be included if they connected to something already communicated in a consultation. Smoking cessation advice was subject to these relevance criteria and was primarily discussed if it posed a particular risk to a particular patient. Smoking cessation advice also occurred in conversations addressing the patient's well-being. If occurring without any other readable frame, smoking cessation advice was apt to be perceived by patients as part of a public campaign.

CONCLUSIONS

Relevance criteria in the shape of communication of particular risks to particular patients and small-talk about well-being reflect the concept of "frames" by Goffman. Criteria of relevance limit the number of issues in individual consultations. Relevance criteria may explain why smoking cessation advice has not yet been implemented in many more consultations.

Preventing Relapse Following Smoking Cessation

Cigarette smoking is the leading cause of preventable deaths worldwide. Long-term smoking cessation can drastically reduce people's risk for developing smoking-related disease. The research literature points to a need for clearer operationalization and differentiation between smoking cessation and relapse prevention interventions and outcomes. That said, extensive meta-analyses and research studies have indicated that there are various efficacious smoking interventions that can both support smoking cessation and relapse prevention efforts. Specifically, behavioral treatments, relapse prevention psychotherapy, pharmacologic interventions, motivational enhancement, smoking reduction to quit, brief advice, alternative intervention modes (telephone, Internet, computer), self-help, and tailored treatments can help prepare smokers for longer-term abstinence. Although these methods vary on reach, they are relatively efficacious, particularly in combined formats.

[Evaluation of hospitalized patients in terms of their knowledge related to smoking]

OBJECTIVE

To identify characteristics related to smoking in hospitalized patients and to assess the knowledge that such patients have regarding the relationship between nicotine dependence and smoking-related diseases.

METHODS

The study included 186 patients (males, 59%; mean age, 51.3 +/- 16.8 years) who were evaluated regarding demographic characteristics, diagnosis at admission, smoking history and passive smoke exposure. All of the patients completed a questionnaire regarding their knowledge of the relationship between smoking and disease.

RESULTS

Of the 186 patients, 42 (22.6%) were smokers, 64 (34.4%) were former smokers and 80 (43%) stated they were never smokers; 136 (73%) reported passive smoke exposure. In the sample as a whole, 21.5% of the patients were diagnosed with a smoking-related disease at admission, compared with 39% of those who were smokers or former smokers. The proportion of individuals who were unaware of the relationship between smoking and the cause of hospitalization was similar among current smokers and former smokers (56% and 65%, respectively). Only 19% of the current smokers believed that smoking might have affected their health, compared with 32% of the former smokers (p = 0.22). The proportion of individuals who believed that quitting smoking depends on willpower was significantly higher among former smokers and never smokers than among current smokers (64% and 53%, respectively, vs. 24%; p < 0.001 and p = 0.008). Although 96% of the patients believed that smoking causes dependence, only 60% identified smoking as a disease.

CONCLUSIONS

This study shows the disconnect between the recognition of smoking as a cause of dependence and the recognition of smoking as a disease, as well as the general lack of awareness that former and current smoking constitute a risk factor for the development and progression of disease.

The effectiveness of interventions to change six health behaviours: a review of reviews

BACKGROUND

Several World Health Organisation reports over recent years have highlighted the high incidence of chronic diseases such as diabetes, coronary heart disease and cancer. Contributory factors include unhealthy diets, alcohol and tobacco use and sedentary lifestyles. This paper reports the findings of a review of reviews of behavioural change interventions to reduce unhealthy behaviours or promote healthy behaviours. We included six different health-related behaviours in the review: healthy eating, physical exercise, smoking, alcohol misuse, sexual risk taking (in young people) and illicit drug use. We excluded reviews which focussed on pharmacological treatments or those which required intensive treatments (e.g. for drug or alcohol dependency).

METHODS

The Cochrane Library, Database of Abstracts of Reviews of Effectiveness (DARE) and several Ovid databases were searched for systematic reviews of interventions for the six behaviours (updated search 2008). Two reviewers applied the inclusion criteria, extracted data and assessed the quality of the reviews. The results were discussed in a narrative synthesis.

RESULTS

We included 103 reviews published between 1995 and 2008. The focus of interventions varied, but those targeting specific individuals were generally designed to change an existing behaviour (e.g. cigarette smoking, alcohol misuse), whilst those aimed at the general population or groups such as school children were designed to promote positive behaviours (e.g. healthy eating). Almost 50% (n = 48) of the reviews focussed on smoking (either prevention or cessation). Interventions that were most effective across a range of health behaviours included physician advice or individual counselling, and workplace- and school-based activities. Mass media campaigns and legislative interventions also showed small to moderate effects in changing health behaviours.Generally, the evidence related to short-term effects rather than sustained/longer-term impact and there was a relative lack of evidence on how best to address inequalities.

CONCLUSIONS

Despite limitations of the review of reviews approach, it is encouraging that there are interventions that are effective in achieving behavioural change. Further emphasis in both primary studies and secondary analysis (e.g. systematic reviews) should be placed on assessing the differential effectiveness of interventions across different population subgroups to ensure that health inequalities are addressed.

Mental health workers' views on addressing tobacco use

OBJECTIVE

The aims of this study were to assess mental health workers' attitudes to addressing tobacco dependence with patients, to identify barriers that may prevent people with mental illness from receiving support, and determine workers' recommendations for tobacco policy and practice change.

METHOD

Questionnaires were sent to government and non-government mental health services in Adelaide, South Australia. The questionnaires asked workers to rate on a Likert rating scale their attitudes to addressing tobacco use with patients and to respond to qualitative questions about managing tobacco use within mental health services. Quantitative data were analysed using SPSS version 15.0 and qualitative data was coded by three researchers into categories or themes and then analysed.

RESULTS

Questionnaires (324) were received from staff across 45 organizations providing clinical and psychosocial services. More than two thirds of the participants felt it was important for mental health services to be involved in assisting patients to quit smoking; however, only 26% said they raised the issue of tobacco use with patients, often or as part of the assessment. Respondents on average felt approximately one third of their patients could quit or reduce tobacco use if they received nicotine replacement therapy, information and support. Most workers suggested changes to policy and practice within mental health services including smoke free areas and the provision of information and support.

DISCUSSION

The rate of tobacco use amongst people with mental illness is still very high with serious social and health consequences. Mental health workers are uniquely placed to assist patients to quit or reduce tobacco use. This study has shown many workers believe that it is important to address tobacco use with their patients as part of routine care and that mental health services should implement significant tobacco policy and practice change.

Strategies to increase the delivery of smoking cessation treatments in primary care settings: a systematic review and meta-analysis

OBJECTIVES

A systematic review and meta-analysis was conducted to evaluate evidence-based strategies for increasing the delivery of smoking cessation treatments in primary care clinics.

METHODS

The review included studies published before January 1, 2009. The pooled odds-ratio (OR) was calculated for intervention group versus control group for practitioner performance for "5As" (Ask, Advise, Assess, Assist and Arrange) delivery and smoking abstinence. Multi-component interventions were defined as interventions which combined two or more intervention strategies.

RESULTS

Thirty-seven trials met eligibility criteria. Evidence from multiple large-scale trials was found to support the efficacy of multi-component interventions in increasing "5As" delivery. The pooled OR for multi-component interventions compared to control was 1.79 [95% CI 1.6-2.1] for "ask", 1.6 [95% CI 1.4-1.8] for "advice", 9.3 [95% CI 6.8-12.8] for "assist" (quit date) and 3.5 [95% CI 2.8-4.2] for "assist" (prescribe medications). Evidence was also found to support the value of practice-level interventions in increasing 5As delivery. Adjunct counseling [OR 1.7; 95% CI 1.5-2.0] and multi-component interventions [OR 2.2; 95% CI 1.7-2.8] were found to significantly increase smoking abstinence.

CONCLUSION

Multi-component interventions improve smoking outcomes in primary care settings. Future trials should attempt to isolate which components of multi-component interventions are required to optimize cost-effectiveness.

Secondhand smoke policy and the risk of depression

BACKGROUND

Banning smoking in work and public settings leads to immediate reductions in disease burden. However, no previous studies have looked specifically at the impact smoking bans may have on depression.

METHODS

The 2006 Behavioral Risk Factor Surveillance System (BRFSS) uses a cross-sectional design representative of the non-institutionalized civilian US population. Never smoker survey participants > or =18 years of age were selected from the BRFSS (n = 41,904) with their self-report of depressive symptoms in the last 2 weeks, as assessed by the Patient Health Questionnaire. Models with adjustment for survey design, sociodemographics, alcohol consumption, and work and home smoking policies were considered.

RESULTS

Following covariate adjustment, the risk of major depression was significantly higher for those living where smoking was allowed anywhere in the home versus those living in homes with complete smoking bans and in those who indicated that smoking was permitted in their work areas versus those reporting complete workplace smoking bans.

CONCLUSIONS

Findings from the present analysis support policies that ban smoking in all workplace settings. Interventions designed to eliminate smoking in the home are also needed.

Interventions for smoking cessation and reduction in individuals with schizophrenia

BACKGROUND

Patients with schizophrenia smoke more heavily than the general population and this contributes to their higher morbidity and mortality from smoking-related illnesses. It remains unclear what interventions can help them to quit or reduce smoking.

OBJECTIVES

To evaluate the benefits and harms of different treatments for nicotine dependence in schizophrenia.

SEARCH STRATEGY

We searched the Cochrane Tobacco Addiction Group Specialized Register and electronic databases including MEDLINE, EMBASE and PsycINFO from inception to April 2010.

SELECTION CRITERIA

We included randomized trials for smoking cessation or reduction, comparing any pharmacological or non-pharmacological intervention with placebo or with another therapeutic control in adult smokers with schizophrenia or schizoaffective disorder.

DATA COLLECTION AND ANALYSIS

Two reviewers independently assessed the eligibility and quality of trials and extracted data. Outcome measures included smoking abstinence, reduction in the amount smoked and any change in mental state. We extracted abstinence and reduction data at the end of treatment and at least six months after the intervention. We used the most rigorous definition of abstinence or reduction and biochemically validated data where available. Any reported adverse events were noted. Where appropriate, we pooled data using a random effects model.

MAIN RESULTS

We included 21 trials (11 trials of smoking cessation; four trials of smoking reduction; one trial for relapse prevention; five trials reported smoking outcomes for interventions aimed at other purposes). Seven trials compared bupropion with placebo; meta-analysis showed that smoking cessation rates after bupropion were significantly higher than placebo at the end of treatment (seven trials, N=340; risk ratio [RR] 2.84; 95% confidence interval [CI] 1.61 to 4.99) and after six months (five trials, N=214, RR 2.78; 95% CI 1.02 to 7.58). Expired carbon monoxide (CO) level and the number of cigarettes smoked daily were significantly lower with bupropion at the end of therapy but not after six months. There were no significant differences in positive, negative and depressive symptoms between bupropion and placebo group. There was no report of major adverse event such as seizures with bupropion.Contingent reinforcement (CR) with money may increase smoking abstinence rates and reduce the level of smoking in patients with schizophrenia. However, it is uncertain whether these benefits are maintained in the longer term. There was no evidence of benefit for the few trials of other pharmacological therapies (including nicotine replacement therapy (NRT)) and psychosocial interventions in helping smokers with schizophrenia to quit or reduce smoking.

AUTHORS' CONCLUSIONS

Bupropion increases smoking abstinence rates in smokers with schizophrenia, without jeopardising their mental state. Bupropion may also reduce the amount these patients smoke. CR may help this group of patients to quit and reduce smoking. We failed to find convincing evidence that other interventions have a beneficial effect on smoking behaviour in schizophrenia.

A framework for developing an evidence-based, comprehensive tobacco control program

Background

Tobacco control is an area where the translation of evidence into policy would seem to be straightforward, given the wealth of epidemiological, behavioural and other types of research available. Yet, even here challenges exist. These include information overload, concealment of key (industry-funded) evidence, contextualization, assessment of population impact, and the changing nature of the threat.

Methods

In the context of Israel's health targeting initiative, Healthy Israel 2020, we describe the steps taken to develop a comprehensive tobacco control strategy. We elaborate on the following: a) scientific issues influencing the choice of tobacco control strategies; b) organization of existing evidence of effectiveness of interventions into a manageable form, and c) consideration of relevant philosophical and political issues. We propose a framework for developing a plan and illustrate this process with a case study in Israel.

Results

Broad consensus exists regarding the effectiveness of most interventions, but current recommendations differ in the emphasis they place on different strategies. Scientific challenges include integration of complex and sometimes conflicting information from authoritative sources, and lack of estimates of population impact of interventions. Philosophical and political challenges include the use of evidence-based versus innovative policymaking, the importance of individual versus governmental responsibility, and whether and how interventions should be prioritized.

The proposed framework includes: 1) compilation of a list of potential interventions 2) modification of that list based on local needs and political constraints; 3) streamlining the list by categorizing interventions into broad groupings of related interventions; together these groupings form the basis of a comprehensive plan; and 4) refinement of the plan by comparing it to existing comprehensive plans.

Conclusions

Development of a comprehensive tobacco control plan is a complex endeavour, involving crucial decisions regarding intervention components. "Off the shelf" plans, which need to be adapted to local settings, are available from a variety of sources, and a multitude of individual recommendations are available. The proposed framework for adapting existing approaches to the local social and political climate may assist others planning for smoke-free societies. Additionally, this experience has implications for development of evidence-based health plans addressing other risk factors.

Postgraduate education for doctors in smoking cessation

INTRODUCTION AND AIMS

Smoking cessation advice from doctors helps improve quit rates but the opportunity to provide this advice is often missed. Postgraduate education is one strategy to improve the amount and quality of cessation support provided. This paper describes a sample of postgraduate education programs for doctors in smoking cessation and suggests future directions to improve reach and quality.

DESIGN AND METHODS

Survey of key informants identified through tobacco control listserves supplemented by a review of the published literature on education programs since 2000. Programs and publications from Europe were not included as these are covered in another paper in this Special Issue.

RESULTS

Responses were received from only 21 key informants from eight countries. Two further training programs were identified from the literature review. The following components were present in the majority of programs: 5 As (Ask, Advise, Assess, Assist and Arrange) approach (72%), stage of change (64%), motivational interviewing (72%), pharmacotherapies (84%). Reference to clinical practice guidelines was very common (84%). The most common model of delivery of training was face to face. Lack of interest from doctors and lack of funding were identified as the main barriers to uptake and sustainability of training programs.

DISCUSSION AND CONCLUSIONS

Identifying programs proved difficult and only a limited number were identified by the methods used. There was a high level of consistency in program content and a strong link to clinical practice guidelines. Key informants identified limited reach into the medical profession as an important issue. New approaches are needed to expand the availability and uptake of postgraduate education in smoking cessation

Physicians' role in advancing tobacco control in China

China has ratified the FCTC and is working towards implementing tobacco control measures to combat the massive health and economic consequences of tobacco use. Physicians will need to play a leading role in this fight as they have done in countries such as Australia where measures to address the tobacco epidemic are more advanced. At present in China barriers such as physicians' own smoking status and underestimation of the impact interventions with their patients can have means that their potentially positive contribution is far from realised. Physicians have a responsibility to lead in tobacco control. This should begin with their own behaviour and practices including quitting smoking if a smoker and counselling patients and families of patients to not smoke. Advocating to make hospitals and medical facilities smokefree should also be a priority for physicians. As centres where people attend to improve their health and receive treatment for illness, allowing a practice such as smoking is completely incongruous. Responsibility also rests with the facilities in which physicians work and the professional bodies who represent them, physicians should be provided with information, training and support to assist them to address their own and their patients tobacco use.

Do financial incentives for delivering health promotion counselling work? Analysis of smoking cessation activities stimulated by the quality and outcomes framework

BACKGROUND

A substantial fraction of UK general practitioners' salaries is now intended to reflect the quality of care provided. This performance-related pay system has probably improved aspects of primary health care but, using the observational data available, disentangling the impacts of different types of targets set within this unique payment system is challenging.

DISCUSSION

Financial incentives undoubtedly influence GPs' activities, however, those aimed at encouraging GPs' delivery of health promotion counselling may not always have the effects intended. There is strong, observational evidence that targets and incentives intended to increase smoking cessation counselling by GPs have merely increased their propensity to record this activity in patients' medical records. The limitations of using financial incentives to stimulate the delivery of counselling in primary care are discussed and a re-appraisal of their use within UK GPs' performance-related pay system is argued for.

SUMMARY

The utility of targets employed by the system for UK General Practitioners' performance related pay may be inappropriate for encouraging the delivery of health promotion counselling interventions. An evaluation of these targets is essential before they are further developed or added to.

Motivating the unmotivated for health behavior change: a randomized trial of cessation induction for smokers

BACKGROUND

Many smokers remain unwilling or unable to make a quit attempt. For these smokers, novel strategies to induce quit attempts are necessary to achieve further reductions in smoking prevalence.

PURPOSE

This article describes the design and methods of an ongoing nationwide telephone-based clinical trial for cessation induction, the principal aim of which is to test the hypothesis that samples of nicotine replacement therapy (NRT), can induce quit attempts among smokers otherwise unmotivated to quit.

METHODS

Smokers are recruited proactively through online channels. A 'behavioral filter' is used to identify and separate motivated versus unmotivated smokers, the latter of whom (N = 750) are formally entered into the clinical trial. Participants are randomized to one of two treatment conditions designed to promote self-efficacy and motivation to quit: (1) practice quit attempt (PQA) or (2) PQA plus NRT sampling. The primary outcome measure tested over a 6-month follow-up is the incidence of additional quit attempts as well as hypothesized mediators of treatment effects.

RESULTS

This study details the challenges of identifying and treating smokers who are unmotivated to quit. Strengths include a novel treatment approach, tested among a group of proactively recruited smokers nationwide, with a unique method of identifying cessation-resistant smokers.

LIMITATIONS

The omission of a true control group, testing the effect of the PQA itself, is an inherent limitation to the study design. Online recruitment presents additional study challenges, all of which are discussed in detail.

CONCLUSIONS

The study has translational potential to guide both clinical and policy recommendations for cessation induction. Further, while the focus is on smoking, this trial may serve as an example to researchers and clinicians who focus on other health behaviors, and who themselves are challenged with motivating people who are unmotivated for change.

Increasing consumer demand for tobacco treatments: Ten design recommendations for clinicians and healthcare systems

Health professionals play an important role in addressing patient tobacco use in clinical settings. While there is clear evidence that identifying tobacco use and assisting smokers in quitting affects outcomes, challenges to improve routine, clinician-delivered tobacco intervention persist. The Consumer Demand Initiative has identified simple design principles to increase consumers' use of proven tobacco treatments. Applying these design strategies to activities across the healthcare system, we articulate ten recommendations that can be implemented in the context of most clinical systems where most clinicians work. The recommendations are: (1) reframe the definition of success, (2) portray proven treatments as the best care, (3) redesign the 5A's of tobacco intervention, (4) be ready to deliver the right treatment at the right time, (5) move tobacco from the social history to the problem list, (6) use words as therapy and language that makes sense, (7) fit tobacco treatment into clinical team workflows, (8) embed tobacco treatment into health information technology, (9) make every encounter an opportunity to intervene, and (10) end social disparities for tobacco users. Clinical systems need to change to improve tobacco treatment implementation. The consumer- and clinician-centered recommendations provide a roadmap that focuses on increasing clinician performance through greater understanding of the clinician's role in helping tobacco users, highlighting the value of evidence-based tobacco treatments, employing shared decision-making skills, and integrating routine tobacco treatment into clinical system routines.

Effectiveness of intensive group and individual interventions for smoking cessation in primary health care settings: a randomized trial

Objectives

Primary: To compare the effectiveness of intensive group and individual interventions for smoking cessation in a primary health care setting; secondary: to identify the variables associated with smoking cessation.

Methods

Three-pronged clinical trial with randomisation at the individual level. We performed the following: an intensive individual intervention (III), an intensive group intervention (IGI) and a minimal intervention (MI). Included in the study were smokers who were prepared to quit smoking. Excluded from the study were individuals aged less than 18 years or with severe mental conditions or terminal illnesses. The outcome measure was continued abstinence at 12 months confirmed through CO-oximetry (CO). The analysis was based on intention to treat.

Results

In total, 287 smokers were recruited: 81 in the III, 111 in the IGI, and 95 in the MI. Continued abstinence at 12 months confirmed through CO was 7.4% in the III, 5.4% in the IGI, and 1% in the MI. No significant differences were noted between III and MI on the one hand, and between IGI and MI on the other [RR 7.04 (0.9-7.2) and RR 5.1 (0.6-41.9), respectively]. No differences were noted between IGI and III [RR 0.7 (0.2-2.2)]. In multivariate analysis, only overall visit length showed a statistically significant association with smoking cessation.

Conclusions

The effectiveness of intensive smoking interventions in this study was lower than expected. No statistically significant differences were found between the results of individual and group interventions.

Tobacco cessation via doctors of chiropractic: results of a feasibility study

INTRODUCTION

There is a sizeable and growing body of empirical literature on the effects of physician advice to quit smoking. Because of the association between tobacco use and the health problems that may provoke referral to chiropractic care, doctors of chiropractic (DCs) may be able to give patients personalized proximal health feedback that may motivate them to quit. However, DCs have not been utilized in this role. The primary aim of this study was to design and refine a brief office-based tobacco intervention for use within chiropractic settings.

METHODS

This study was conducted in 20 private chiropractic practices in 2 phases: (a) intervention development, in which we created and focus tested practitioner and patient materials, and (b) feasibility, in which we evaluated the impact of the intervention on 210 tobacco-using chiropractic patients.

RESULTS

Analyses were conducted on 156 patients who exclusively smoked cigarettes. Using an intent-to-treat approach, assuming all nonresponders to be smokers, 13 (8.3%) reported 7-day abstinence at 6 weeks, 22 (14.1%) at the 6-month follow-up, and 35 (22.4%) at the 12-month assessment. Eleven participants (7.1%) reported prolonged abstinence at the 6-month follow-up, and 15 (9.6%) reported prolonged abstinence at 12 months.

CONCLUSIONS

To our knowledge, this is the first study to refine a brief office-based treatment for tobacco dependence for use in chiropractic settings. The results of this study were promising and will lead to a randomized clinical trial. If found to be effective, this model could be disseminated to chiropractic practitioners throughout the United States.

Motivational interviewing for smoking cessation

BACKGROUND

Motivational Interviewing (MI) is a directive patient-centred style of counselling, designed to help people to explore and resolve ambivalence about behaviour change. It was developed as a treatment for alcohol abuse, but may help smokers to a make a successful attempt to quit.

OBJECTIVES

To determine the effects of motivational interviewing in promoting smoking cessation.

SEARCH STRATEGY

We searched the Cochrane Tobacco Addiction Group Specialized Register for studies with terms (motivational OR motivation OR motivating OR motivate OR behavi* OR motivat*) and (interview* OR session* OR counsel* OR practi*) in the title or abstract, or as keywords. Date of the most recent search: April 2009.

SELECTION CRITERIA

Randomized controlled trials in which motivational interviewing or its variants were offered to smokers to assist smoking cessation.

DATA COLLECTION AND ANALYSIS

We extracted data in duplicate. The main outcome measure was abstinence from smoking after at least six months follow up. We used the most rigorous definition of abstinence in each trial, and biochemically validated rates where available. Subjects lost to follow up were treated as continuing smokers. We performed meta-analysis using a fixed-effect Mantel-Haenszel model.

MAIN RESULTS

We identified 14 studies published between 1997 and 2008, involving over 10,000 smokers. Trials were conducted in one to four sessions, with the duration of each session ranging from 15 to 45 minutes. All but two of the trials used supportive telephone contacts, and supplemented the counselling with self-help materials. MI was generally compared with brief advice or usual care in the trials. Interventions were delivered by primary care physicians, hospital clinicians, nurses or counsellors. Our meta-analysis of MI versus brief advice or usual care yielded a modest but significant increase in quitting (RR 1.27; 95% CI 1.14 to 1.42). Subgroup analyses suggested that MI was effective when delivered by primary care physicians (RR 3.49; 95% CI 1.53 to 7.94) and by counsellors (RR 1.27; 95% CI 1.12 to 1.43), and when it was conducted in longer sessions (more than 20 minutes per session) (RR 1.31; 95% CI 1.16 to 1.49). Multiple session treatments may be slightly more effective than single sessions, but both regimens produced positive outcomes. Evidence is unclear at present on the optimal number of follow-up calls.There was variation across the trials in treatment fidelity. All trials used some variant of motivational interviewing.Critical details in how it was modified for the particular study population, the training of therapists and the content of the counselling were sometimes lacking from trial reports.

AUTHORS' CONCLUSIONS

Motivational interviewing may assist smokers to quit. However, the results should be interpreted with caution due to variations in study quality, treatment fidelity and the possibility of publication or selective reporting bias.

The attitude toward tobacco dependence and barriers to discussing smoking cessation: a survey among Turkish general practitioners

OBJECTIVES

To evaluate the general attitude of a sample of Turkish general practitioners (GPs) toward tobacco dependence and to assess their knowledge and behavior regarding smoking cessation (SC).

METHODS

A self-administered questionnaire modified from WHO, Global Health Professional Survey was distributed to GPs, working in our district, Isparta.

RESULTS

As much as 41% of GPs were current smokers. Ever smokers were generally less likely to agree with statements that would change their freedom to smoke in certain places. While 46% of GPs frequently inquired about tobacco use in their patients, 13.5% did not advise any of their patients to quit smoking during the month preceding the questionnaire. The most common barriers reported by GPs to discussing SC with their patients were as follows: considering the discussion not to be effective (57.8%), having low confidence in knowledge (48.1%), having unpleasant personal experience or considering it a thankless task (46.1%).

CONCLUSIONS

It appears essential to reduce the number of GPs who smoke and to improve GP training on SC procedures for integrating SC treatment into primary care in Turkey.

Comparative effectiveness of 5 smoking cessation pharmacotherapies in primary care clinics

BACKGROUND

Randomized efficacy clinical trials conducted in research settings may not accurately reflect the benefits of tobacco dependence treatments when used in real-world clinical settings. Effectiveness trials (eg, in primary care settings) are needed to estimate the benefits of cessation treatments in real-world use.

METHODS

A total of 1346 primary care patients attending routine appointments were recruited by medical assistants in 12 primary care clinics. Patients were randomly assigned to 5 active pharmacotherapies: 3 monotherapies (nicotine patch, nicotine lozenge, and bupropion hydrochloride sustained release [SR]) and 2 combination therapies (patch + lozenge and bupropion SR + lozenge). Patients were referred to a telephone quit line for cessation counseling. Primary outcomes included 7-day point prevalence abstinence at 1 week, 8 weeks, and 6 months after quitting and number of days to relapse.

RESULTS

Among 7128 eligible smokers (> or =10 cigarettes per day) attending routine primary care appointments, 1346 (18.9%) were enrolled in the study. Six-month abstinence rates for the 5 active pharmacotherapies were the following: bupropion SR, 16.8%; lozenge, 19.9%; patch, 17.7%; patch + lozenge, 26.9%; and bupropion SR + lozenge, 29.9%. Bupropion SR + lozenge was superior to all of the monotherapies (odds ratio, 0.46-0.56); patch + lozenge was superior to patch and bupropion monotherapies (odds ratio, 0.56 and 0.54, respectively).

CONCLUSIONS

One in 5 smokers attending a routine primary care appointment was willing to make a serious quit attempt that included evidence-based counseling and medication. In this comparative effectiveness study of 5 tobacco dependence treatments, combination pharmacotherapy significantly increased abstinence compared with monotherapies. Provision of free cessation medications plus quit line counseling arranged in the primary care setting holds promise for assisting large numbers of smokers to quit.

Quit smoking advice from health professionals in Taiwan: the role of funding policy and smoker socioeconomic status

Objectives

In 2002, Taiwan launched a program to encourage doctors to provide brief cessation counselling to their patients during routine outpatient visits. This study is to compare and analyse the annual prevalence rate of receiving advice to quit smoking from health professionals before (2004) and after (2005, 2006) the increase in funding and the withdrawal of additional funding (2007).

Methods

We analysed pooled data from 2004 to 2007 Taiwan Adult Tobacco Survey, an annual random digit dialling telephone survey, to estimate the prevalence of receiving quit advice among ever smokers across these years. Smoking characteristics and the socioeconomic factors of smokers associated with receipt of advice to quit smoking were also examined.

Results

The prevalence rate of receiving quit advice increased from 21.1% in 2004 to 28.2% in 2006, and then decreased slightly to 27.6% in 2007 after the funds were cut. Multivariate analyses results indicated that increasing financing for smoking cessation services in 2005, being male, older, a daily cigarette user, having previously attempted to quit, perceiving oneself as having poor health and being aware of the benefits of smoking cessation services were significantly positively associated with receiving quit advice from health professionals. In contrast, smokers who were younger, female and occasional cigarette users were less likely to receive quit advice. Also, smokers with socioeconomic disadvantages were not less likely to receive quit advice.

Conclusions

During the period of increased funding for smoking cessation services, the rates of receiving quit advice increased among all smokers and across different socioeconomic groups.

Serious psychological distress among adults with and without disabilities

OBJECTIVES

Our objective was to examine the extent to which serious psychological distress (SPD) is associated with behavioral and social correlates among US adults with self-reported disabilities.

METHODS

Self-reported data on disability, SPD, and behavioral and social correlates were collected from 202,383 participants (aged > or = 18 years) of the 2007 Behavioral Risk Factor Surveillance System. Adults with self-reported disabilities were identified using two standardized questions--one relating to activity limitation, the other to special equipment.

RESULTS

The age-adjusted prevalence of SPD among adults with disabilities was nearly seven times higher than among adults without disabilities (14.1 % vs. 1.8 %, respectively). Adults with disabilities who have both activity limitations and who use assistive technology, and those with activity limitations only consistently experienced a higher prevalence of SPD than those who used assistive technology only (age-adjusted prevalence: 21.0 % and 12.7 % vs. 4.9 %). After adjusting for age, sex, race/ethnicity, educational attainment, marital status, and employment status, in the past 30 days SPD was more common among Hispanic persons, and was significantly associated with younger age, lower educational attainment, marital history, and employment status. Adults with SPD and disabilities experienced increased levels of risk behaviors, life dissatisfaction, and inadequate social support. Most importantly, just over half of adults with disabilities and SPD (51.6 % [95 % CI = 48.6-54.6]) were receiving medical care for a mental health condition compared to 20.6 % (95 % CI = 19.9-21.3) without SPD.

CONCLUSIONS

Given that SPD is strongly associated with both the behavioral and psychosocial determinants of health, this work underscores the need for evidence-based interventions that may reduce its prevalence among people living with disabilities.

Receipt of provider advice for smoking cessation and use of smoking cessation treatments among cancer survivors

BACKGROUND

As the number of cancer survivors increases, the assessment and intervention for smoking among survivors are increasingly important.

OBJECTIVE

This study examined the extent to which cancer survivors reported being asked and advised about smoking by health-care providers and their use of smoking cessation treatments during quit attempts.

DESIGN

The data were drawn from the 2005 National Health Interview Survey, an annual health survey of US adults.

PARTICIPANTS

The participants were 1,825 individuals who reported being diagnosed with cancer at least 1 year previously and provided data regarding their current smoking status.

MEASUREMENTS

Participants completed items assessing demographics, health and health-care factors, and smoking-related variables.

MAIN RESULTS

More than three-quarters of participants (81.0%) reported that their smoking status was known by a health-care provider. Among current smokers (17.6%) who visited a health-care provider in the past year, 72.2% reported being advised to quit smoking by a provider. Factors associated with a higher rate of receiving advice to quit included greater cigarette consumption (P=0.008), more medical comorbidities (P= 0.001), high psychological distress (P= 0.003), and lack of health-care insurance (P = 0.03). Among current smokers who tried to quit in the last year, 33.5% used pharmacotherapy cessation treatment and 3.8% used an evidence-based behavioral treatment.

CONCLUSIONS

This study reveals considerable missed opportunities for health-care providers to advise cancer survivors about smoking and provide evidence-based interventions. Systematic efforts are needed to increase the provision of smoking cessation advice and use of cessation treatments among cancer survivors.

How confident should we be that smoking cessation treatments work?

AIM

To determine (i) the concordance among recent meta-analyses about which treatments for smoking cessation are efficacious; (ii) the similarity of odds ratios (ORs) across meta-analyses; and (iii) among the validated treatments, the proportion of studies that found higher quit rates.

METHODS

Computerized literature search for meta-analyses during the last 5 years in PubMed and PsychInfo. Data were extracted from summary tables of overall effect of validated treatments.

RESULTS

Fourteen meta-analyses agreed 100% on the presence/absence of efficacy of 17 proven treatments. The ORs differed by <0.5 in 72/76 of the comparisons of meta-analyses. Among 37 comparisons in 33 comparisons, >85% of the studies reported numerical superiority for the active treatment.

CONCLUSIONS

The efficacy of treatments for smoking cessation are extremely reliable. This argues for inclusion of treatment as an essential feature of tobacco control and clinical practice and argues for reimbursement of smoking cessation treatments on a par with other medical and behavioral disorders.
