Nurse-assisted counseling for smokers in primary care

Predictors of tobacco control among nursing students

As the most numerous health care providers, nurses could reduce tobacco-related morbidity and mortality. A cross-sectional survey of 476 junior and senior students at 12 schools of nursing in the New York metropolitan area was conducted, to determine nurse knowledge of tobacco control, their attitudes, beliefs, and practices. Overall, 76% of all nursing students reported that they practiced tobacco control. Current smokers were less likely to participate in tobacco control with targets ranging from the nurse herself to the community than either never or ex-smokers. Nurses were more likely to engage in tobacco control among individual, family, or group clients than to advocate for changes in the community. Student nurses who were African American or Hispanic, had never smoked or were ex-smokers, those who had better knowledge of cessation approaches, and those who tended to have more confidence in their cessation counseling skills were more likely to engage in multi-target tobacco control than other similar nurses. Tailored interventions that emphasize discrete counseling skills are suggested.

Helping parents to stop smoking: which interventions are effective?

Parental smoking increases children's risk of respiratory illness. Encouraging parents not to smoke in the home helps, but stopping smoking altogether is more effective in reducing children's exposure. The prevalence of smoking increases with higher levels of social disadvantage and is therefore a major contributor to widening inequalities in health. Randomised trials have shown that adults can be helped to stop with simple advice from health professionals, behavioural support, nicotine replacement and antidepressants.

Barriers to tobacco cessation in clinical practice: report from a National Survey of Oncology Nurses

This study describes the survey results of a national random sample of members of the Oncology Nursing Society who reported the greatest number of barriers to delivering a tobacco cessation intervention with their patients. Nurses who perceived the greatest number of barriers were more likely to be current smokers and to be young and were less likely to have an advanced degree, to be a nurse practitioner, or to have administrative responsibilities. Those with greater barriers were less likely to deliver tobacco cessation interventions.

Smoking cessation in the hospitalized patient using the transtheoretical model of behavior change

Tobacco use continues to be the most prevalent cause of preventable morbidity and mortality in the United States, causing more than 430,000 deaths each year, or 1 in every 5 deaths. In addition, many health care providers employed in critical care settings deal with patients who have experienced a near-death event that has led them to consider smoking cessation. The smoking cessation rate 1 year after a myocardial infarction is approximately 70% in those patients who receive a smoking cessation intervention. Theory-based smoking cessation interventions have been found to be effective. The purpose of this article is to present the transtheoretical model as basis for developing a hospital-based smoking cessation intervention. In addition, symptom management options will be discussed.

Reviews of evidence regarding interventions to reduce tobacco use and exposure to environmental tobacco smoke

This report presents the results of systematic reviews of effectiveness, applicability, other effects, economic evaluations, and barriers to use of selected population-based interventions intended to reduce tobacco use and exposure to environmental tobacco smoke. The related systematic reviews are linked by a common conceptual approach. These reviews form the basis of recommendations by the Task Force on Community Preventive Services (TFCPS) regarding the use of these selected interventions. The TFCPS recommendations are presented on page 67 of this supplement.

Meeting national tobacco challenges: recommendations for smoking cessation groups

PURPOSE

To review the literature on model smoking cessation programs and provide an overview of the practice guidelines for intensive smoking cessation groups.

DATA SOURCES

Selected evidence-based literature and AHCPR/AHRQ clinical practice guidelines.

CONCLUSIONS

Smoking is the leading cause of preventable death in our global society and is expected to kill more people than any other disease within 20 years. Data support that most smokers want to quit and are more likely to succeed with a combination of behavioral and pharmacological support.

IMPLICATIONS FOR PRACTICE

Smoking cessation must be a priority in the delivery of patient care. Intensive interventions are more effective than brief interventions and should be available for all smokers.

Tobacco cessation skills certification in Arizona: application of a state wide, community based model for diffusion of evidence based practice guidelines

OBJECTIVE

To describe the development and preliminary results from a community based certification model for training in tobacco cessation skills in Arizona.

DESIGN

A programme evaluation using both quantitative pre-post measures and qualitative methods.

SETTING

Arizona's comprehensive tobacco control programme of state funded, community based local projects and their community partners providing tobacco treatment services for geographically, socioeconomically, and ethnically diverse communities.

INTERVENTION

A three tiered model of skills based training emphasising Agency for Health Care Policy and Research guidelines, and utilising a training of trainers approach to build community capacity. Certification roles addressed basic tobacco cessation skills, tobacco cessation specialist, and tobacco treatment services manager.

PARTICIPANTS

Initial target audience was community based local project personnel and their community partners, with later adoption by community organisations unaffiliated with local projects, and the general public. MAIN EVALUATION MEASURES: Process measures: participant satisfaction, knowledge, skills, and self-efficacy.

OUTCOME

participant demographics, community organisations represented, post-training, cessation related activities.

RESULTS

During the model's implementation year, 1075 participants attended certification training, 947 participants received basic skills certificates and 82 received specialist certificates. Pre, post, and three month measures of self efficacy showed significant and durable increases. Analysis of participant characteristics demonstrated broad community representation. At post-training follow up, 80.9% of basic skills trainees had performed at least one brief intervention and 74.8% had made a referral to intensive services. Among cessation specialists, 48.8% were delivering intensive services and 69.5% were teaching basic skills classes.

CONCLUSIONS

Initial experience with Arizona's state wide, community based model for certification of tobacco cessation skills training suggests this model may be a promising method for broad, population based diffusion of evidence based tobacco cessation guidelines.

Human immunodeficiency virus infection, AIDS, and smoking cessation: the time is now

Treatments for persons who are infected with human immunodeficiency virus (HIV) or who have developed AIDS have advanced to the point where death is no longer the inevitable outcome of diagnosis. Combination antiretroviral therapy has made HIV infection less of a terminal condition and more of a medically manageable chronic disease. Thus, efforts to improve the health status and quality of life of HIV-infected persons have become one of the highest treatment priorities for the next decade. Cigarette smoking is highly prevalent among HIV-infected persons, and quitting smoking would greatly improve the health status of these individuals. However, to date, no studies have evaluated the efficacy of a smoking-cessation intervention specifically tailored to this population. This article reviews the evidence and rationale for advancing smoking-cessation treatments specifically tailored to the needs of HIV-infected persons and provides recommendations for future treatment studies.

Using radon risk to motivate smoking reduction: evaluation of written materials and brief telephone counselling

OBJECTIVE

Radon and cigarette smoking have synergistic effects on lung cancer, even when radon concentrations are relatively low. Working through an electric utility company, we sought to reach smoking households with low radon concentrations and motivate smoking cessation or prohibiting smoking in the home.

DESIGN

Eligible homes (n = 714) were randomised to receive: (1) the Environmental Protection Agency's (EPA's) "A citizen's guide to radon"; (2) a specially developed pamphlet; or (3) that pamphlet plus brief telephone counselling.

PROCEDURE

Utility company "bill stuffers" offered free radon test kits to smoking households. All households received radon test results with an explanatory cover letter. Both the specially developed pamphlet and the telephone counselling emphasised that smoking cessation or prohibiting smoking in the home were the optimal risk reduction strategies. Households were followed up at 3 and 12 months after receiving materials.

RESULTS

The specially developed pamphlet and the EPA guide yielded similar outcomes. There was a non-significant trend for telephone counselling to produce greater sustained quitting than the specially developed pamphlet, and phone counselling led to significantly more new household smoking bans.

CONCLUSIONS

Working through a public utility company is an efficient way to reach smoking households, and brief telephone counselling is a promising method for promoting household smoking bans and cessation in homes alerted to the risk posed by the combination of radon and smoking.

Why have we been more successful in reducing tobacco use than violent crime?

Tobacco control efforts have been associated with a significant reduction in the prevalence of tobacco use in the United States. Efforts to reduce the incidence of violent crime have been much less successful. This paper argues that progress on tobacco control stems from the existence of a clear, empirically based, and widely understood analysis of the tobacco problem that articulates (a) the harms associated with its use, (b) the causes of tobacco use, and (c) the programs and policies that could reduce tobacco use. This analysis has guided the development of a network of social organizations that have been advocating for policies and programs that are reducing tobacco use. In contrast, there is not a widely shared, cogent, and empirically based analysis of the problem of violent crime. As a result, efforts to combat violent crime are fragmented and it has proven difficult to generate support for preventive programs and policies. Substantial empirical progress has been made, however, on how violent crime could be prevented. That evidence is reviewed. It is argued that the articulation of this evidence is a critical first step for achieving widespread reduction in the incidence of violent crime. Communication of that evidence to audiences that matter will require that behavioral scientists become better organized to advocate for the adoption of empirically supported practices.

Skill mix between nurses and doctors working in primary care-delegation or allocation: a review of the literature

The fundamental role of primary health care teams (PHCT) is to deliver effective services to the local population. Demands on the PHCT have increased since the early 1990s and, with the advent of Primary Care Groups (PCGs), will continue to do so in a primary health care led National Health Service (NHS). Rapid changes, however, raise questions about the feasibility and delivery of new services with skill mix and the distribution of workload within the PHCT being key issues. This paper reviews the literature on workload in primary care, attitudes to delegation, inter-professional relationships and teamworking and concludes that in order to deliver the vision of a primary care led NHS, meet the health care needs of users, address the inevitable anxieties of general practitioners and bring forth the professional aspirations of nurses and other health care professionals, more equitable and less hierarchical models of multi-professional teamworking in primary care will be most successful.

The value of interrupted time-series experiments for community intervention research

Greater use of interrupted time-series experiments is advocated for community intervention research. Time-series designs enable the development of knowledge about the effects of community interventions and policies in circumstances in which randomized controlled trials are too expensive, premature, or simply impractical. The multiple baseline time-series design typically involves two or more communities that are repeatedly assessed, with the intervention introduced into one community at a time. It is particularly well suited to initial evaluations of community interventions and the refinement of those interventions. This paper describes the main features of multiple baseline designs and related repeated-measures time-series experiments, discusses the threats to internal validity in multiple baseline designs, and outlines techniques for statistical analyses of time-series data. Examples are given of the use of multiple baseline designs in evaluating community interventions and policy changes.

The role of health professionals in a community-based program to help women quit smoking

BACKGROUND

Health professionals are credible sources of smoking cessation advice. This study describes changes in health professionals' reported provision of smoking cessation counseling activities for women during a community health education project that took place in two intervention counties (I) and compares these to reports from health professionals in two similar comparison counties (C).

METHODS

Specific smoking cessation activities reported by physicians (I n = 73, C n = 73), dentists (I n = 51, C n = 46), dental hygienists (I n = 38, C n = 44), family planning and WIC (Special Supplemental Food Program for Women, Infants and Children) counselors (I n = 14 C n = 16), and community mental health counselors (I n = 57, C n = 23) were assessed by mailed surveys at baseline, after 4 years of countywide interventions, and 2 years later.

RESULTS

Compared with health professionals in the comparison counties, significant increases in smoking cessation training (P < 0.01) and in reported referral of women to stop smoking groups, support groups, and one-to-one support were noted for physicians, family planning, and WIC counselors (P < 0.001); in training and referral to stop smoking groups and support groups by dentists and dental hygienists (P < 0.05); and in referral to support groups by community mental health counselors (P < 0.05). Significant increases in setting quit dates (P < 0.05) and providing self-help materials (P < 0.01) were also noted for family planning and WIC counselors. These effects were no longer demonstrable 2 years after external support for the countywide interventions was withdrawn.

CONCLUSIONS

We suggest that an important aspect of facilitating consistent smoking cessation advice and counseling from health professionals in the future will be the provision of a broader range of regularly available smoking cessation support systems within communities than is generally available at this time in the United States.

Methods to enhance smoking cessation after myocardial infarction

The evidence linking smoking and coronary artery disease is quite strong, and there is also a positive relationship between smoking cessation and reduction in cardiovascular disease risk. Nicotine replacement therapy and bupropion are effective treatments for smoking cessation and are most effective when combined with behavioral counseling. Intensive multicomponent interventions that include a case-management component have produced the highest smoking cessation rates for patients who suffer a myocardial infarction.

Theories and intervention approaches to health-behavior change in primary care

Providers typically rely on health information and their professional status to convince patients to change. Health-behavior theories and models suggest more effective methods for accomplishing patient compliance and other behavior change related to treatment regimens. Behavior modification stresses the remediation of skill deficits or using positive and negative reinforcement to modify performance. Like behavior modification, the Health Belief Model stresses a reduction of environmental barriers to behavior. Social Learning Theory suggests that perceptions of skills and reinforcement may more directly determine behavior. Self-management models put the above theories into self-change actions. Social support theories prioritize reinforcement delivered through social networks, whereas the Theory of Reasoned Action emphasizes perceptions of social processes. Finally, the Transtheoretical Model speaks of the necessity to match interventions to cognitive-behavioral stages. Strategies derived from each of these theories are suggested herein.

Nursing intervention and smoking cessation: A meta-analysis

OBJECTIVE

To determine with meta-analysis the effects of nursing-delivered smoking cessation interventions.

RESULTS

Fifteen studies comparing nursing intervention with a control or usual care found intervention to significantly increase the odds of smoking cessation. There was heterogeneity among the study results, but pooling by using a random effects model did not alter the estimate of effect. There was no evidence from indirect comparison that interventions classified as intensive had a larger effect than less intensive ones. There was evidence that interventions were more effective for hospital inpatients with cardiovascular disease than for inpatients with other conditions. Interventions in nonhospitalized patients also showed evidence of efficacy. Nurse counseling on smoking cessation during a screening health check was likely to have less effect. The results indicate the potential benefits of smoking cessation advice and counseling given by nurses to their patients, with reasonable evidence that intervention can be effective.

Interventions to implement a clinic-based smoking cessation guideline within a staff model HMO

Smoking cessation guideline development has become widespread, outpacing guideline implementation efforts. To address this problem, HealthPartners undertook a randomized trial of strategies to enhance compliance of a smoking cessation guideline. The intervention aimed at clinic leadership resulted in significantly more compliance, as measured by physicians coding "tobacco use" on a billing form. The intervention aimed at all clinic physicians had no significant effect. The study suggests that smoking cessation guideline efforts should focus on clinic leadership and system changes rather than on all staff physicians.

Can brief intervention through community dental care have an effect on adolescent smoking?

BACKGROUND

Community dental clinics are good settings for smoking intervention. The aim here was to put forward a strategy for preventing adolescent smoking by means of a brief intervention.

METHODS

A total of 2,586 12-year-olds participated in this follow-up study. They were asked upon arrival for their annual routine dental examination to complete a smoking questionnaire and were randomly assigned to either the intervention group or the usual care control group according to the last digit of their date of birth (odd or even). The intervention comprised annually inquiring about smoking, showing photographs of the harmful effects of smoking on the teeth, allowing participants to examine their own mouth with a mirror, and finally counselling them in accordance with their answer to the question on smoking habits. The smoking status reported was not verified by other means.

RESULTS

The prevalence of smoking at the end of the 2-year follow-up was 18.1%, in the intervention group and 20.8% among the controls. However, no statistically significant differences between groups were found.

CONCLUSIONS

These results reflect the difficulties of achieving successful results with long-term smoking cessation programs with adolescents in unstable conditions.

Passive smoking exposure of sick children in Hong Kong

1. This study aims to investigate the extent of passive smoking exposure of sick children in Hong Kong; their father's smoking behaviors and their mother's action to protect the child from environmental tobacco smoke (ETS). 2. This cross-sectional survey was the first phase of a randomized controlled trial on a health education intervention provided by nurses in the general paediatric wards of four major hospitals in Hong Kong. The subjects are non-smoking mothers of sick children admitted to hospital and with a smoking husband living together in the same household with the child. Eligible subjects completed a self-administered baseline questionnaire before entering into the trial. 3. All the 848 children whose mothers completed the questionnaire during December 1997 to April 1998 had a smoking father. They constituted about 24% (95% CI: 22.6-24.9%) of all the sick children during the same period. More than half of the children's fathers (55%; 51.6-58.3%) smoked 1-14 cigarettes per day and about 68% (64.7-71.0%) of them were daily smokers for over 10 years. Over half (53%; 49.4-56.2%) of the fathers smoked 1-14 cigarettes at home every day. About 21% of the fathers smoked near the child occasionally and 31% (27.4-33.6%) smoked 1-14 cigarettes near the child per day. About 16% of the children lived with more than one smoker (2-3). About 86% (83.3-88.0%) of the children had 1-3 smokers who smoked at home and 61% (58.1 - 64.7%) of them had 1-3 smokers who smoked near them every day. However, 70% of the children were reported by their mothers as exposed to ETS at home. This percentage (70%) was less than the percentage (86%) of smokers who smoked at home daily. About 31.1% of the mothers reported symptoms of coughing and running nose (20.6%) in their children when they were exposed to ETS. To protect the child from ETS exposure, 43% of the mothers requested the father not to smoke near the child, 33.1% requested the father to smoke less cigarettes and 31.5% advised the father to quit smoking. 4. In conclusion, sick children in Hong Kong are at risk of exposure to ETS, but not all mothers are aware of the health risks and their actions were inadequate. There is a critical need to promote awareness of ETS exposure and the health risks in the family in Hong Kong so as to reduce illness and hospital admission in children.

Reaching those most in need: participation in a Planned Parenthood smoking cessation program

We evaluated the representativeness of women approached and enrolled in a brief smoking cessation intervention conducted in Planned Parenthood clinics. In this effectiveness study, regular clinic staff were trained to identify, offer participation, and counsel willing smoking clients as part of their clinic visit. Chart audits were conducted to determine the percent of clients who had smoking status identified, as well as the percent and characteristics of potentially eligible clients who were not approached. Baseline and non-participant questionnaires were analyzed to determine participation rate and characteristics of those participating versus those not participating. Smoking status was documented in 99% of charts. Seventy percent of eligible smokers were approached about study participation and 74% of those approached participated. There were no significant differences between those approached and those not approached or between those who participated versus those who did not on a host of sociodemographic variables. This project was able to approach and attract a representative sample of young, lower income women to participate in a brief, clinic-based smoking cessation program.

Prevention: tobacco control and cancer nursing

In the next century, tobacco will become the number-one cause of preventable death throughout the world, resulting in half a billion deaths. As global patterns of tobacco use change, tobacco-related morbidity and mortality will shift from developed countries to developing countries. Internationally, lung cancer will become the fifth leading cause of preventable death, affecting an increasing number of women. Tobacco cessation after a diagnosis of cancer may decrease treatment-related morbidity and increase survival. With the increasing number of cancer survivors, tobacco cessation becomes an important part of rehabilitation. This article aims to provide a foundation for developing strategies to involve cancer nurses throughout the world in an international campaign to prevent tobacco-related morbidity and mortality. The devastating health impacts of tobacco are reviewed, and highlights of new scientific findings about nicotine addiction are presented. New approaches to tobacco prevention, legislation, and regulatory policies are discussed. Tobacco assessment strategies and treatment interventions for use in cancer nursing clinical practice are reviewed, and global strategies for nursing action in tobacco control are offered.

Evaluation of a nurse-delivered smoking cessation intervention for hospitalized patients with cardiac disease

OBJECTIVE

To determine the effect of a nurse-delivered smoking cessation intervention for hospitalized smokers on smoking cessation rates and smoking cessation self-efficacy at 6 months after enrollment.

DESIGN

A quasi-experimental design was used; specifically, a nonequivalent control group design was implemented.

SETTING

A 450-bed major teaching and research tertiary care hospital, serving patients from across the province of British Columbia, Canada.

SUBJECTS

Smokers with a cardiac diagnosis (n = 102) who were admitted to 1 of 2 inpatient cardiac units for medical or surgical treatment.

OUTCOME MEASURES

Self-reported smoking status and self-reported smoking cessation self-efficacy.

INTERVENTION

Two structured, in-hospital contacts, followed by 3 months of telephone support. The interventions focused on problem-solving and reinforcing the patient's self-efficacy.

RESULTS

Of the patients enrolled, 86 completed 6-month follow-up questionnaires. When subjects who were lost to follow-up were assumed to be smokers, 46% of the intervention group, compared with 31% of the control group, were nonsmokers. When key variables were controlled, we found that those subjects in the control group were 3 times more likely to relapse and begin smoking than those who received the intervention. There were no significant differences in follow-up smoking cessation self-efficacy scores in the treatment and control groups. When background variables were controlled, self-efficacy related to positive/social situations and habit/addictive situations were noted to be significantly higher in the intervention group.

CONCLUSION

The findings of this research are encouraging; they suggest that a nurse-delivered smoking cessation intervention improved the smoking cessation rate in patients with cardiac disease.

Activity counseling by primary care physicians

Modifying patients' sedentary lifestyle, a risk factor for many chronic diseases, is a challenge to health professionals. Although physicians can play a vital role in promoting physical activity among sedentary patients, the prevalence of physician-based exercise counseling is low. This paper presents a review of studies that have targeted physicians as agents of behavior change. Changing sedentary behavior is more likely to be effective when the intervention is grounded in theory. This paper outlines an integration of two theoretical models that have potential for enhancing behavior change, and it describes specific techniques for physicians interested in promoting a more active lifestyle among their patients.

Minority women and tobacco: implications for smoking cessation interventions

Quitting smoking is the single most important preventive health behavior a woman can perform to significantly reduce her chances of morbidity and premature mortality. Minority women are an extremely important population to target for smoking cessation intervention. Rates and risk factors for cardiovascular diseases and cancer are markedly higher among women of certain minority groups. In addition, smoking prevalence rates in women of some ethnic groups are elevated relative to the majority population of women, and specific groups have displayed slower rates of decline in smoking. Furthermore, minority women tend to have less access and appear to be less responsive to smoking cessation programs aimed at the majority culture. Thus, consideration of the practical and cultural needs of ethnic minority women is imperative when designing smoking intervention programs. This article describes the smoking behaviors of African-American, American Indian and Native Alaskan, Asian and Pacific Islander, and Hispanic women smokers, in order to gain a greater understanding of the treatment needs of these women. Information on prevalence rates and smoking patterns, barriers to quitting, and findings from intervention studies within each population are reviewed as well as recommendations for smoking cessation treatment.

Nested consent design for clinical trials

BACKGROUND

Since random treatment allocation is hardly understood by the majority of patients, a new 'nested consent design' for clinical trials is proposed.

PROPOSED DESIGN

The design consists of a two-step enrollment of study subjects. The first step is the enrollment of participants into a follow-up study, where consent to be subjects involved in the follow-up is obtained. The second step is the enrollment of randomly sampled eligible participants into a new treatment group. After the explanation of (1) treatment mode, (2) additional burdens associated with the proposed treatment and (3) expected effects and possible adverse events, written informed consent is obtained. Those who reject participation and those who are not allocated into the new treatment are treated by standard care. Endpoints are set to be the same for all follow-up study participants whether allocated into the new treatment or not, and follow-up is carried out in the same manner. Analyses are performed between those allocated to the new treatment and those non-allocated on an intent-to-treat basis.

EXAMPLE

Although not a clinical trial, this design was applied in a smoking cessation program at Aichi Cancer Center Hospital for first-visit patients who answered in a questionnaire survey that they were smokers. Out of 1330 necessary participants, 324 were enrolled in the follow-up study during the first three months of enrollment.

CONCLUSIONS

The design was found to be feasible for prevention trials, and possibly for clinical trials to compare a new treatment with a standard treatment. There seems to be no ethical difference between this design and the one-arm study design.

Reductions in STD infections subsequent to an STD clinic visit. Using video-based patient education to supplement provider interactions

BACKGROUND AND OBJECTIVES

Video-based patient education has been effective in a variety of clinical settings. The authors studied the efficacy of a video-based educational intervention in an inner-city public sexually transmitted diseases (STD) clinic.

GOAL

To evaluate the efficacy of video-based patient education in reducing STD infections subsequent to a clinic visit.

DESIGN

African-American and Hispanic men attending a large public STD clinic were assigned at random to either an experimental video-based educational intervention or a control condition in which they received regular clinic services. Patients in the experimental group were exposed to video-based interventions that provided information about STDs and their prevention, portrayed positive attitudes about condom use, and modeled appropriate strategies for encouraging condom use in different sexual relationships. During 1992, 2,004 subjects were tracked for an average of 17 months through the New York City STD surveillance database for the occurrence of new STD infections.

RESULTS

The overall rate of new infection among male STD clinic patients was 24.2%. Rate of new infection was significantly lower among those exposed to video-based prevention education than among controls (22.5% compared with 26.8%, p < .05). Subjects reporting multiple sex partners had a significantly higher new infection rate but also experienced the greatest impact of educational intervention. There was a 32.2% new infection rate among high-risk controls compared with a 24.8% rate among high-risk intervention groups (p < 0.025).

CONCLUSION

Results of this randomized clinical trial indicate that using video-based patient education to supplement regular STD clinic services and provider interactions can be effective in reducing rates of new STD infection, particularly among those at greatest risk.

Physician-based smoking intervention: a rededication to a five-step strategy to smoking research

It is well established that physicians can have a significant effect on the smoking behavior of their patients. To do this, attention must be paid to putting in place multiple strategies or mechanisms in the organization where the physician practices, as well as in the macroenvironment (i.e., social and public policy). It has been questioned whether or not there is stagnation in the field of clinical smoking intervention requiring a rededication to basic research regarding smoking. With respect to physician-based smoking intervention, we alternatively suggest that recommitment to all phases of research is essential for moving forward physician-based smoking interventions in the rapidly changing health services and social environment. In this article, we first review the essential framework of the National Cancer Institute's research science approach to cancer prevention and control. Evidence concerning physician-based interventions is then reviewed, followed by a schematic of a comprehensive framework for thinking about the process and intervention components needed for physician-based smoking intervention to take place in the health-care setting, the impact they have, and the eventual outcome of such interventions. There is a discussion of the challenges for the delivery of smoking-cessation services presented by the rapidly changing healthy delivery system of the 1990s. Finally, we present recommendations concerning research priorities for physician-based smoking intervention and the research funding process.

Discrepancies between meta-analyses and subsequent large randomized, controlled trials

BACKGROUND

Meta-analyses are now widely used to provide evidence to support clinical strategies. However, large randomized, controlled trials are considered the gold standard in evaluating the efficacy of clinical interventions.

METHODS

We compared the results of large randomized, controlled trials (involving 1000 patients or more) that were published in four journals (the New England Journal of Medicine, the Lancet, the Annals of Internal Medicine, and the Journal of the American Medical Association) with the results of meta-analyses published earlier on the same topics. Regarding the principal and secondary outcomes, we judged whether the findings of the randomized trials agreed with those of the corresponding meta-analyses, and we determined whether the study results were positive (indicating that treatment improved the outcome) or negative (indicating that the outcome with treatment was the same or worse than without it) at the conventional level of statistical significance (P<0.05).

RESULTS

We identified 12 large randomized, controlled trials and 19 meta-analyses addressing the same questions. For a total of 40 primary and secondary outcomes, agreement between the meta-analyses and the large clinical trials was only fair (kappa= 0.35; 95 percent confidence interval, 0.06 to 0.64). The positive predictive value of the meta-analyses was 68 percent, and the negative predictive value 67 percent. However, the difference in point estimates between the randomized trials and the meta-analyses was statistically significant for only 5 of the 40 comparisons (12 percent). Furthermore, in each case of disagreement a statistically significant effect of treatment was found by one method, whereas no statistically significant effect was found by the other.

CONCLUSIONS

The outcomes of the 12 large randomized, controlled trials that we studied were not predicted accurately 35 percent of the time by the meta-analyses published previously on the same topics.

Smoking cessation. 3: Needed healthcare policy changes

Smoking is the primary preventable cause of mortality and morbidity in our society, killing more than 430,000 people each year--more than 1,000 a day. Despite this deadly record, the treatment of nicotine dependence has not been integrated into routine medical care. Although professionals from many healthcare fields can be effective providers of smoking cessation treatment, relatively few actually advise patients to quit smoking; and even fewer assist their patients in quitting. Systematic changes in healthcare policies are needed to rectify these problems and improve the provision of smoking cessation services. In this article, the issues of who should be providing cessation treatment, why more providers do not offer this service, and what changes should be made to ensure more widespread inclusion of smoking cessation treatment in future healthcare practice are examined.

Smoking cessation. 2: Components of effective intervention

Smoking cessation treatment is an essential component of comprehensive healthcare, but many healthcare providers lack formal training and are hesitant to provide such intervention. The recently published US Agency for Health Care Policy and Research (AHCPR) Smoking Cessation Clinical Practice Guideline provided empirically based recommendations to address these issues. The most effective components of smoking cessation include the use of nicotine replacement therapy, provider support and encouragement, and training in such skills as problem solving and coping. Methods of using these recommendations are illustrated, and sample scripts are offered to serve as references for providers from various disciplines who conduct smoking cessation interventions.

Training chemical dependency counselors to treat nicotine dependence

To test the effectiveness of providing chemical dependency (CD) staff with a knowledge-and-skills-building workshop on treatment of nicotine dependence, we employed a nested cross-sectional design with six outpatient CD programs in Nebraska (3 intervention, 3 control sites). Data on tobacco counseling provided by CD staff were obtained by telephone from sequential samples of smokers currently receiving alcohol treatment at each participating site. Intervention site clients with clinic visits after the staff training workshop were no more likely than intervention-site clients with clinic visits before the workshop to report having been counseled about their smoking (OR = 0.95, 95% confidence interval (CI): 0.74-1.21). However, control-site clients were significantly more likely to report having been counseled about smoking during the second half of the study (OR = 2.15, 95% CI: 1.49-3.08), even though staff training was not provided at control sites until data collection had been completed. These findings suggest that in some alcohol treatment programs simple monitoring of staff counseling practices may be sufficient to increase the frequency of attention to tobacco. In others, more intensive efforts might be needed to shift CD staff toward more consistent treatment of nicotine dependence.

Reducing maternal smoking and relapse: long-term evaluation of a pediatric intervention

BACKGROUND

Pediatric well-care visits provide a clinical opportunity to counsel new mothers about their smoking and the deleterious effects of environmental tobacco smoke (ETS) on infant health.

METHODS

Forty-nine Oregon pediatric offices enrolled 2,901 women who were currently smoking or had quit for pregnancy, using a brief survey at the newborn's first office visit. Randomly assigned offices provided advice and materials to mothers at each well-care visit during the first 6 months postpartum to promote quitting or relapse prevention.

RESULTS

The intervention reduced smoking (5.9% vs 2.7%) and relapse (55% vs 45%) at 6-month follow-up, but logistic regression analysis at 12 months revealed no significant treatment effect. The intervention had a positive effect on secondary outcome variables, such as readiness to quit and attitude toward and knowledge of ETS. Multiple logistic regression analysis indicated that husband/partner smoking was the strongest predictor of maternal quitting or relapse.

CONCLUSIONS

A pediatric office-based intervention can significantly affect smoking and relapse prevention for mothers of newborns, but the effect decreases with time. Consistent prompting of the provider to give brief advice and materials at well-care visits could provide a low-cost intervention to reduce infant ETS exposure.

The future of smoking cessation therapy in the United States

Six trends that are likely to influence the future content, format, delivery and reach of smoking cessation therapy in the United States are discussed: (1) changing characteristics of smokers (e.g. more likely to be poor, have psychiatric co-morbidity and be more nicotine dependent), (2) health care reform demands for cost-effectiveness, (3) development of guidelines/algorithms that recommend stepped-care approaches, (4) continued emphasis on smoking as a form of drug dependence requiring intensive pharmacological and behavior therapy for some smokers, (5) interest in harm-reduction strategies for smokers unable or unwilling to quit (and 6) smoking cessation therapies become reimbursable on par with other drug dependencies.

Brief nurse consultations for preventing alcohol use among urban school youth

This study examined the effects of brief nurse consultations in preventing alcohol use among inner-city youth. Participants included 138 sixth-eighth grade students attending an inner-city public school in Jacksonville, Florida. Subjects were randomly assigned by computer to either the intervention (STARS program) or a control group. Baseline and three-month post-tests were conducted at the target school site. A significant difference was found on heavy alcohol use with intervention subjects showing a reduction and control subjects an increase in heavy drinking (t = -2.33, 120df, p = .02). No differences were found between groups on other alcohol use measures. This study's findings indicate that a series of brief nurse consultations appear to reduce heavy alcohol consumption among urban school youth.

Tobacco cessation interventions in health care settings: rationale, model, outcomes

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

Patient-physician interactions in diabetes management: consistencies and variation in the structure and content of two consultations

The structure and content of medical consultations concerning diabetes were examined in two, successive quarterly medical consultations between two physicians and their diabetes patients (N = 44). The consultations were audio-taped and coded for structure (e.g. question asking, information giving) using a modified version of the Roter Interactional Analysis System (inter-coder correlations typically exceeded 0.90 for the composite variables derived from the coding system). The tapes were also coded for content by monitoring the topics discussed (e.g. diet, medication, exercise). The majority of the interactions consisted primarily of information giving and positive talk on the part of both patients and providers. Nutrition-related issued, blood glucose monitoring, medication and exercise were addressed in the majority of interactions, but other regimen areas such as foot care, smoking habits, and alcohol were seldom discussed. There was little stability across the two consultations in terms of either structure (median test-retest correlation = 0.24) or content (majority of test-retest correlations were below 0.30). The importance of studying more than one patient-physician encounter when studying interaction style and content is discussed, as is the need for investigation of interactions between non-physician health care providers and patients with chronic disease.

Cigarette smoking and coronary heart disease: risks and management

Tobacco smoking is the leading preventable cause of death in the United States and an important cause of CHD. The effect of smoking on the cardiovascular system and coronary risk factors is pervasive. Unfavorable effects include acute increases in blood pressure and coronary vascular resistance, reduction in oxygen delivery, enhancement of platelet aggregation, increased fibrinogen, and depression of HDL cholesterol. Smoking cessation reduces cardiovascular morbidity and mortality rates relatively rapidly, even among individuals who stop smoking only after the age of 65 or after developing the clinical manifestations of CHD including myocardial infarction. Behavioral smoking-cessation programs and nicotine-replacement therapy each have been demonstrated to be effective for the treatment of smoking. The most effective treatment currently available is to combine the two. Nicotine-replacement therapy is safe and effective in patients with stable coronary heart disease. Although the threat or diagnosis of CHD is a powerful stimulus to spontaneous smoking cessation, many smokers continue to smoke after events such as myocardial infarction or CABG surgery. Studies have demonstrated that physician advice to stop smoking, supplemented by brief counseling by a nurse and follow-up, dramatically increases the smoking-cessation rate of patients hospitalized with myocardial infarction and is highly cost effective. In the outpatient setting, physician advice and counseling is also effective in helping smokers with or without CHD to stop smoking. This article outlines a simple protocol that has been demonstrated to be effective for counseling smokers.

Settings as an important dimension in health education/promotion policy, programs, and research

Settings--community, worksite, schools, and healthcare sites--constitute an important dimension of health education/health promotion policy and programs and for research about program needs, feasibility, efficacy, and effectiveness. These settings vary in the extent of coverage of and relationships with their respective constituencies, valued outcomes, and quantity and quality of evidence about the effectiveness of setting-specific and cross-setting programs. Main sources of evidence for program efficacy and effectiveness are summarized, leading to the conclusion that strides have been made toward building a strong evidentiary base for health education/health promotion in these settings. Gaps in research exist, especially for diffusion of effective programs, new technologies, the influence of policy, relations between settings, and approaches to marginal and special subgroups. Recommendations are offered for cross-setting and within-setting research related to intervention.

Creating capacity through health education: what we know and what we don't

Researchers in health education have rarely convened to outline research priorities in the field. This article discusses the results of a meeting to develop a research agenda aimed at creating capacity to promote and maintain health. Salient research findings related to individual and community health are summarized and priority issues for future research are presented.

Making the most of a teachable moment: a smokeless-tobacco cessation intervention in the dental office

OBJECTIVES

Primary care medical clinics are good settings for smoking interventions. This study extends this strategy with a smokeless tobacco intervention delivered by dentists and dental hygienists in the course of routine dental care.

METHODS

Male users of moist snuff and chewing tobacco (n = 518) were identified by questionnaire in clinic waiting rooms and then randomly assigned to either usual care or intervention. The intervention included a routine oral examination with special attention to the part of the mouth in which tobacco was kept and an explanation of the health risks of using smokeless tobacco. After receiving unequivocal advice to stop using tobacco, each patient viewed a 9-minute videotape, received a self-help manual, and was briefly counseled by the dental hygienist.

RESULTS

Long-term success was defined as no smokeless tobacco use at both 3- and 12-month follow-ups, with those lost to follow-up counted as smokeless tobacco users. The intervention increased the proportion of patients who quit by about one half (12.5% vs 18.4%, P < .05).

CONCLUSIONS

These results demonstrate the efficacy of a brief dental office intervention for the general population of smokeless tobacco users.
