Physician-delivered interventions for smoking cessation: strategies for increasing effectiveness

If physicians and other health-care providers were able to facilitate long-term cessation in 1 of every 10 smokers--a safe estimate based on the outcomes of randomized physician-delivered intervention studies--almost 4 million smokers would become former smokers. Evidence from randomized trials and observational studies demonstrates that physicians who intervene with smokers have an impact on their cigarette-smoking behavior. Greater smoking cessation occurs as physician interventions become more intensive and contacts more frequent. Adding modalities such as counseling, self-help booklets, and nicotine-containing chewing gum appears to augment the effectiveness of advice alone. The consistent demonstration of the need for follow-up and the possible use of several modalities is not unlike the demonstrated components of effective overall management approaches to such medical problems as hypertension. Surveys have indicated that physicians often do not intervene because they experience a low success rate with smokers. Educational programs have demonstrated substantial success in training physicians to counsel smokers; therefore, new goals for medical education, house-staff training, and continuing medical education need to include the development of skills and office management practices that can be used by providers to facilitate health-promoting behaviors among their patients. This article reviews the impact of physician-delivered smoking interventions on smokers, physician attitudes toward intervention, and physicians' reported intervention practices. It identifies those strategies that have been demonstrated to be effective in an out-patient office setting and emphasizes the need for every smoker to be considered a candidate for intervention.     

General practitioners' views on and referral to NHS smoking cessation services

OBJECTIVES: Increasing the rate of smoking cessation remains a major public health goal. To help achieve this in the UK, National Health Service (NHS) smoking cessation services have been established to provide treatment for smokers wanting help with stopping. Referrals from general practitioners (GPs) are crucial to the success of these clinics. This study aimed to assess English GPs' self-reported interactions with, and attitudes towards, their local smoking cessation services. STUDY DESIGN: Postal survey assessing the attitudes of GPs in England towards, and formal interactions with, NHS smoking cessation services. METHODS: A questionnaire was posted to a random sample of 544 GPs in England (response rate 63%). GPs' self-reported interactions with smoking cessation services and their attitudes towards these clinics were assessed. GPs were also asked what factors determined whether they prescribed nicotine-replacement therapy (NRT) and Buproprion (Zyban), and what was the extent and nature of their smoking cessation interventions with their patients. RESULTS: Most GPs (94%) reported that they were aware of the specialist smoking cessation service in their area. Seventy percent of GPs supported the continuation of current funding for specialist smoking cessation services. Seventy percent reported that they referred patients to these services, and 55% had staff within their practices trained as community smoking cessation advisors. Most GPs (79%) reported 'clinical need' as a determinant of whether they prescribed NRT/Zyban, and a few GPs cited 'budgetary constraints' as a factor (15%). Ninety-eight percent of GPs reported that they record smoking status when new patients join their practice, and they advise smokers to stop 'at least every now and then'. CONCLUSIONS: GPs support the existence and continuation of specialist smoking cessation services, and most reported that they refer patients to them. Virtually every GP reported that they record smoking status when new patients join their practice, and they advise smokers to stop 'at least every now and then'.     

Peer Reviewed: Smoking Status and Cessation Counseling Practices Among Physicians,Guangxi, China, 2007

Introduction

We examined Chinese physicians'' smoking behavior, knowledge of smoking''s health effects, and compliance with accepted cessation counseling practices.

Methods

We used a structured questionnaire adapted from the Global Health Professionals Survey of the World Health Organization to survey Chinese physicians based at 5 hospitals in Nanning, Guangxi Province, China.

Results

The response rate was 85% for a total of 673 completed questionnaires. Of the 673 respondents, 73% were men, 42% were aged 30 years or younger, and 26% were smokers (men, 35%; women, 3%). Only 28% of the smokers were ready to quit immediately. A substantial proportion of physicians did not have adequate knowledge of smoking-related health hazards or favorable attitudes toward smoking cessation counseling. Asking patients whether they smoked and recording smoking status in the medical record were significantly associated with being female and being very well or somewhat prepared to counsel patients about smoking cessation. Advising patients to quit smoking was significantly associated with being female, being a nonsmoker, being very well or somewhat prepared to counsel patients about smoking cessation, and having read any smoking cessation guidelines.

Conclusions

Our findings suggest that smoking is common among male Chinese physicians and that Chinese physicians have inadequate knowledge of smoking''s health hazards and of how to help smokers quit. Physicians in China and their patients who smoke would benefit from widely accessible Chinese clinical practice guidelines on smoking cessation, better medical school education about the health risks of smoking, and government funding of cessation medications.     

A randomized trial of physician training for smoking cessation

Abstract This randomized controlled trial investigated the effects of a smoking cessation workshop on physician practices and on patients' smoking behavior. Eighty-three community family physicians were randomly allocated by practice to either 1) a Usual Care condition, 2) a group in which physicians were not trained but were asked to address smoking cessation with specific patients, or 3) a condition which included physician training as well as printed resources and in which specific patients were identified as smokers. The intervention taught to the physicians through a four hour training workshop included providing advice about stopping smoking, the setting of a date for stopping, the offer of nicotine gum, take-home materials, and the offer of follow-up visits. The intervention was described, demonstrated, and the physicians practiced with simulated patients. The outcome of the intervention was assessed in terms of physician behavior and patient smoking behavior. Exit interviews with patients demonstrated that patients of trained physicians did not differ from patients of untrained physicians on how willing they were to try to stop smoking nor on their receptiveness to nicotine gum. However, there was a small but statistically significant difference favoring the patients from the trained physician group who successfully stopped smoking.     

Smoking cessation intervention practices in Chinese physicians: do gender and smoking status matter?

Healthcare settings provide a major arena for administering smoking cessation interventions. However, few studies have reported differences in the frequency of practice in healthcare professionals by gender and smoking status. This might also be influenced by a difference in smoking prevalence by gender, especially in China and other developing countries. This study examined factors associated with the frequency of cessation intervention practices by smoking status among Chinese physicians in men and women. A cross-sectional survey was conducted in 2006 in physicians with direct patient contact from nine hospitals in Guangzhou with a response rate of 60.8%. Significantly more female physicians who were non-smokers (79.7%) reported "initiation and/or advice" smoking cessation interventions than male physicians who were smokers (71.2%) and non-smokers (71.6%). Factors significantly associated with "initiation and/or advice" were prior smoking cessation training (OR = 4.2, 95% CI 1.8-9.6) and lack of knowledge to help patients to quit (OR = 0.4, 95% CI 0.2-0.9) among male physicians who smoked; and organisational support (OR = 1.7, 95% CI 1.3-2.2) and successful past experience (OR = 0.4, 95% CI 0.2-1.0) among male physicians who did not smoke. Among female physicians who did not smoke, significant factors were agreeing that quitting smoking is the most cost-effective way to prevent chronic disease and cancer (OR = 3.0, 95% CI 1.4-6.1), helping patients stop smoking is part of expected role and responsibility (OR = 2.0, 95% CI 1.0-3.7), lack of knowledge to help patients to quit (OR = 0.5, 95% CI 0.2-1.0) and organisational support (OR = 1.3, 95% CI 1.0-1.6) for non-smoking female physicians. This study is the first to show that male physicians were less likely to provide smoking cessation counselling regardless of their smoking status while non-smoking female physicians were more active in advising patients on quitting. The findings highlight the need for developing tailored smoking cessation training programmes for physicians according to their smoking status and gender in China.

A community view of smoking cessation counseling in the practices of physicians and dentists.

The practice norms of community physicians and dentists in the Lehigh Valley of Pennsylvania for counseling about smoking cessation were surveyed. In addition, 1,373 residents in the valley were interviewed by telephone about the smoking counseling behaviors of their dentists and physicians. These activities were conducted as part of the planning for an intervention by the Coalition for a Smoke-Free Valley, a coalition of 100 persons and organizations in the area. The survey response rate for 172 physicians was 77 percent, and for 103 dentists, it was 76 percent. More physicians than dentists advised patients to quit, counseled patients, provided materials, and helped the patient to set a quit date. However, there was a clear discrepancy between what physicians say they do and what smokers say they hear.     

Use of medical counseling for the prevention and control of smoking in the municipality of old Havana

Physicians have an important responsibility for addressing smoking cessation and prevention with their patients. The objective of this study was to describe the use of physician counseling for the prevention and control of smoking and to predict its use according to physician characteristics. A cross-sectional survey of a random sample of 121 family physicians in one municipality of the city of Havana was used to address sociodemographic factors, years of practice in the community, smoking status, use of physician counseling in daily practice (ask, advise, and assist), and the role of physician counseling as an intervention. Summary statistics were used as well as canonical and discriminant analyses. The prevalence of smoking among the physicians was 18%. The smoking status of patients was determined “almost always” by 32% of doctors. Twenty-five percent asked their patients whether they intended to stop smoking; 35% recommended smoking cessation; and 38% gave advice on how to achieve this. More than half (58%) explored factors that might influence cessation in their patients, and 12% reported doing this “frequently.” Physician characteristics were associated significantly with preventive behavior, with community involvement, and with the perceived value of physician counseling and smoking status. Physician responses were associated with actual practice in 82% of the cases. Predisposing, facilitating, and reinforcing factors for preventive behavior were strong determinants of active involvement by physicians in daily practice. Training of health professionals must include smoking cessation.     

Is provider training effective? Changes in attitudes towards smoking cessation counseling and counseling behaviors of home health care nurses

OBJECTIVE: We prospectively examined whether training home health care nurses is associated with changes in attitudes towards smoking cessation counseling and counseling behaviors. METHODS: We trained 98 home health care nurses to deliver cessation counseling to their patients. Measures were administered at pre-training, post-training, and 6 months later. This was part of a larger study conducted in Providence, RI, USA (1998-2002). RESULTS: Compared with pre-training, at post-training, nurses reported significantly higher levels of self-efficacy to counsel, positive outcome expectations, optimism that patients would follow their advice, perceived worth of smoking counseling, perceived importance of quitting smoking, and perceived organizational support. These training effects were maintained 6 months later. Between the end of training and the 6-month follow-up, nurses reported significant increases in their perceived effectiveness to counsel smokers and confidence to encourage behavior change. Compared with pre-training, at 6 months of follow-up, nurses were significantly more likely to ask about smoking status, assess readiness to quit, advise to quit, assist with quitting, and arrange follow-up. Nurses spent significantly more time counseling smokers at 6 months than at pre-training, and were less likely to selectively counsel. CONCLUSIONS: Brief training facilitates both short- and long-term changes in nurse attitudes and behaviors regarding smoking cessation counseling.     

Patterns and predictors of smoking cessation among users of a telephone hotline.

Most former cigarette smokers in the United States have stopped without formal assistance. However, a large proportion of smokers desire and seek help other than by attending formal programs. It is important to recognize what factors are likely to influence the effectiveness of smoking cessation attempts among these persons. The authors report results of a prospective cohort study of 1,552 smokers who called a stop smoking hotline to request self-help smoking cessation information. The participants were classified into three groups based on reports at the 6-month followup: 242 quitters, 497 recidivists, and 813 nonquitters. Baseline and followup data were used to evaluate three comparisons: quitters versus nonquitters, quitters versus recidivists, and recidivists versus nonquitters. Nonquitters appear to be less motivated and more doubtful of their abilities to quit successfully compared with the other two groups. Quitters appear to live in a supportive environment for smoking cessation. Heavier smokers are more hesitant to try to quit, but once they make an attempt they are as likely to succeed as lighter smokers, when other factors are kept constant. Efforts to promote environments supportive of smoking cessation are likely to result in a larger number of successful quitters. Similarly, efforts to strengthen motivation and belief in personal ability to quit are likely to encourage more nonquitters to attempt to stop smoking. Finally, it appears that some smokers need a previous quit attempt before they are able to maintain cessation successfully.     

Reported cessation advice given to African Americans by health care providers in a community health clinic

Physician smoking cessation advice has been shown to be effective in encouraging patients to attempt cessation. Few studies have examined factors associated with patient-reported physician advice in an inner city community health clinic. Smokers identified via chart review and provider referral met with a study smoking specialist. Eligible participants self-identified as African American, smoked at least 1 cigarette per day in the prior 7 days, were 18 or older, had access to a telephone, and agreed to consider blood testing for genetic susceptibility to lung cancer. Of the 869 smokers identified, 487 were eligible and completed a brief in-person and a more extensive follow-up telephone survey within one week after their visit. Patient reports of smoking cessation advice by providers were regressed on patient demographic, smoking, health, and social support variables. Seventy percent of participants reported that they had been advised to quit smoking. Smokers who were older, did not smoke menthol cigarettes, were in poorer health, and who had a regular health care provider were most likely to report having received advice. Patients in this community health setting reported high rates of provider advice to quit smoking. Yet, even in this optimal condition, young healthy smokers did not report receiving advice, even when they were ready to quit smoking. Providers may need additional training and prompting to counsel young healthy smokers about the importance of cessation.     

Physician-delivered advice to quit smoking among Italian smokers

OBJECTIVE: A clinical practice guideline for smoking cessation was released in Italy in 2002, but to date little is known about the implementation of these recommendations among primary care physicians. The objectives of this study were to estimate the prevalence of receiving physician-delivered advice to quit smoking and to determine what factors were related to the receipt of advice among adult Italian smokers. METHODS: The data were collected as part of the Italian 2004-2006 adult tobacco surveys (analyzed in 2007), conducted by DOXA, the Italian branch of the Gallup International Association, and representative of the population aged>or=18 years. Each year smokers were asked whether they had received advice to quit smoking from their family physician during the previous year. Demographic, socioeconomic, tobacco-related, and physician-related variables were examined for their association with the receipt of advice. A logistic regression model was then fit to the data to determine which variables were related to receiving advice to quit smoking. RESULTS: Overall, 22% of smokers reported receiving advice to quit smoking from their physician in the previous year. Less likely to receive advice to quit were smokers who: were single (compared to divorced, widowed, or separated); lived in the South; had a higher level of education; were lighter smokers; had no previous quit attempts; and had physicians who likely smoked. CONCLUSIONS: The data suggest that Italian physicians are not advising smokers to quit at a high rate. Future research should focus on methods that encourage physicians to counsel smokers to quit during a patient-provider encounter.     

A controlled trial to integrate smoking cessation advice into primary care practice: Doctors Helping Smokers, Round III.

BACKGROUND. Although most physicians believe that smoking cessation assistance is important for their patients, the majority of smokers report that they have not received smoking cessation advice from a physician. We therefore tested whether on-site recruitment, training, and organizational assistance in incorporating a smoking intervention system of documented efficacy into nonvolunteer primary care practices would result in higher rates of smoking cessation advice to patients. METHODS. This was a nonrandomized trial comparing all 10 primary care clinics in an intervention area to all 8 primary care clinics from a geographically separate control area. The evaluation was based on the smoking intervention activities of each of the clinics as reported on preintervention and postintervention mail surveys of cohorts of regular smokers seen in the clinics. RESULTS. Preintervention, 22.9% +/- 11.2% of the intervention clinic cohort and 21.9% +/- 9.6% (P = .84) of the control clinic cohort reported that they had been asked about tobacco during a clinic visit in the prior 6 months. Postintervention, the intervention clinic cohort was significantly more likely to report that someone had asked them if they smoked (39.8% +/- 12.3% vs 26.0% +/- 12.2%; P less than .05), that their physician asked them to quit if they were currently smoking (40.5% +/- 12.1% vs 26.4% +/- 14.6%; P less than .05), and that someone had commended them if they had recently quit smoking (28.2% +/- 19.8 vs 11.3% +/- 11.8%; P less than .05). CONCLUSIONS. The intervention significantly increased the rates at which a population of primary care clinics identified their patients who smoked, advised them to quit smoking, and commended those who had recently quit smoking.     

Smoking prevalence, attitudes, and perceived smoking prevention and control responsibilities and behaviors among physicians in Jordan

This study identifies smoking prevalence among physicians in Jordan. It also assesses their attitudes, perceived smoking prevention, and control responsibilities and behaviors. A cross-sectional survey was administered to 251 physicians from public and private hospitals in Jordan. The response rate was 67%. The prevalence of smoking is 22.4% for male and 9.1% for female physicians. Among current or former smokers, 81.1% (n = 73), 29.1% overall, had smoked in front of a patient. The physicians believed that physician counseling could more effectively prevent patients from smoking than influencing patients to quit smoking. Approximately 56.2% of physicians had ever counseled patients about smoking and 34.3% regularly counseled patients about smoking. Only 18.3% (n = 46) had received training, either in medical school or thereafter, on counseling patients about smoking. Physicians with training on counseling patients about smoking cessation were significantly more likely to have counseled or to routinely counsel patients to help them quit or not start smoking. Training also lowered the percentage of smokers who smoked in front of patients.     

Smoking habits and associated factors among Greek physicians

OBJECTIVE: To investigate the smoking habits and associated risk factors among Greek physicians. STUDY DESIGN: Cross-sectional survey of a randomly selected sample of Greek physicians. METHODS: A national sample of 1284 physicians (718 men, 566 women) participated in the study, which was conducted between September 2003 and June 2005. Data were collected through an anonymous self-completed questionnaire. Logistic regression was used to analyse the influence of different factors on the probability of a physician being a current or former smoker. RESULTS: Overall, 38.6% of the physicians (40% of men; 37% of women) currently smoked, 13.8% were former smokers, and 47.6% had never smoked. Eighty-three per cent of smokers reported starting smoking before the age of 25 years, with half of them during medical school (aged 19-24 years). Multivariate analyses revealed that physicians who were male, unmarried, divorced or widowed, surgeons or anaesthetists, and residents were more likely to be current smokers. Former smokers were more likely to be older, male and born in a rural area. Moreover, the odds of being a current or former smoker were significantly higher among physicians with a history of parents who smoked. The proportion of physicians who reported counselling patients (often or always) to stop smoking was lower among current smokers compared with those who never smoked or those who were former smokers (74.4% vs. 85.3% vs. 84.7%, P<0.0001). CONCLUSIONS: The prevalence of smoking among Greek physicians is exceedingly high and similar to that of the general population. More effective interventions that reduce smoking in the medical community should be implemented immediately so that physicians will be better able to fulfil their function as role models for the general population.     

Comparison of the smoking behaviour and attitudes of smokers who believe they have smoking-related problems with those who do not

BACKGROUND: Motivation to stop smoking is associated with smokers' possessing substantial smoking-related morbidity or believing that they have symptoms caused by smoking, but it is not clear if this holds for smokers attending general practice consultations. OBJECTIVE: Our aim was to compare the attitudes and behaviour of smokers attending their GP with symptoms that they believe are smoking related with those who do not. METHOD: A cross-sectional, pre-consultation survey of patients attending GPs in Leicester, UK was carried out. RESULTS: A total of 83.8% (2955/3525) of people attending GPs completed the questionnaire and 34.7% were smokers. Multiple logistic regression showed that where smokers perceived that their problems were smoking related they were more likely to have tried stopping in the past [odds ratio (OR) 1.78, 95% confidence interval (CI) 1.26-2.67], to want to stop smoking (OR 1.83, CI 1.15-2.9) or to intend to stop in the near future (OR 1.58, CI 1.03-2.43). CONCLUSION: Smokers who attend GPs' routine consultations and believe that they have smoking-related problems are more motivated to stop than others. This suggests that it is important for GPs to ascertain patients' views about the aetiology of their symptoms before discussing smoking with them.     

Smoking cessation during pregnancy: strategies used by Michigan family physicians

This study reports the attitudes and strategies of members of the Michigan Academy of Family Physicians about their antismoking interventions for pregnant smokers. Of the 978 physicians surveyed, 607 (62 percent) returned completed questionnaires. Three hundred twenty-three (53 percent) were not practicing obstetrics. The remaining 284 physicians currently practicing obstetrics constituted the study group. Ninety-four percent of these physicians routinely assessed smoking status at the first prenatal visit. Ninety-eight percent advised pregnant smokers to quit smoking during pregnancy. The most frequently used method of intervention was personal counseling (97 percent), followed by referral to smoking cessation clinics (40 percent), and behavior modification (20 percent). Fifty-seven percent of the physicians reported using antismoking pamphlets, and 30 percent used antismoking posters designed for pregnant women. Only 11 percent of the physicians surveyed were generally satisfied with the effectiveness of their current methods. Nonetheless, 97 percent were convinced that the benefits of smoking cessation during pregnancy merited their efforts. The physicians in this sample consistently have advised their pregnant smokers to quit, but most believe there is a need for more effective smoking cessation methods.     

Tobacco cessation in Vietnam: Exploring the role of village health workers

The purpose of this study was to explore current tobacco use treatment (TUT) practice patterns, and attitudes and beliefs among Village Health Workers (VHWs) about expanding their role to include delivering smoking cessation interventions and the perceived barriers. We conducted a survey of 449 VHWs from 26 communes in Thai Nguyen province, Vietnam. We assessed TUT practice patterns including asking about tobacco use, advising smokers to quit, offering assistance (3As) and attitudes, self-efficacy, and norms related to TUT. Seventy two per cent of VHWs reported asking patients if they use tobacco, 78.6% offered advice to quit, and 41.4% offered cessation assistance to few or more patients in the past month. Self-efficacy was low, with 53.2% agreeing that they did not have the skills to counsel patients about smoking cessation. The most commonly reported barriers to offering TUT were a lack of training and perceived lack of patient interest. Greater awareness of their commune health centre’s smoke-free policy and higher levels of self-efficacy were associated with screening and offering cessation assistance. VHWs support an expanded role in tobacco cessation, but require additional resources and training to increase their self-efficacy and skills to provide effective treatment.
