Integrating individual and public health perspectives for treatment of tobacco dependence under managed health care: A combined stepped-care and matching model

Ultra-brief intervention for problem drinkers: research protocol

BACKGROUND

Helping the large number of problem drinkers who will never seek treatment is a challenging issue. Public health initiatives employing educational materials or mass media campaigns have met with mixed success. However, clinical research has developed effective brief interventions to help problem drinkers. This project will employ an intervention that has been validated in clinical settings and then modified into an ultra-brief format suitable for use as a public health intervention. The major objective of this study is to conduct a randomized controlled trial to establish the effectiveness of an ultra-brief, personalized feedback intervention for problem drinkers.

METHODS/DESIGN

Problem drinkers recruited on a baseline population telephone survey conducted in a major metropolitan city in Canada will be randomized to one of three conditions - a personalized feedback pamphlet condition, a control pamphlet condition, or a no intervention control condition. In the week after the baseline survey, households in the two pamphlet conditions will be sent their respective pamphlets. Changes in drinking will be assessed post intervention at three-month and six-month follow-ups. Drinking outcomes will be compared between experimental conditions using Structural Equation Modeling. The primary hypothesis is that problem drinkers from households who receive the personalized feedback pamphlet intervention will display significantly improved drinking outcomes at three and six-month follow-ups as compared to problem drinkers from households in the no intervention control condition. Secondary hypotheses will test the impact of the intervention on help seeking, and explore the mediating or moderating role of perceived drinking norms, perceived alcohol risks and the problem drinker's social reasons for drinking.

DISCUSSION

This trial will provide information on the effectiveness of a pamphlet-based personalized feedback intervention for problem drinkers in a community setting.

A survey of tobacco-related knowledge, attitudes and behaviours of primary care providers in Mississippi

RATIONALE

Relative to other regions in the USA, Mississippi has a high prevalence of tobacco use and tobacco-related disease. This study assessed the tobacco-related knowledge, attitudes and intervention behaviours of family doctors, dentists and nurse practitioners in the state of Mississippi.

METHODS

The Provider Attitude Survey, an 85-item measure of tobacco-related knowledge, attitudes and intervention behaviours was mailed to all members of Mississippi's Family Medicine, Dentistry and Nurse Practitioner professional organizations (N=2043).

RESULTS

Over one-third (n=802, 39.2%) of eligible providers responded. Just 24.3% had received training in tobacco cessation and 33.7% were aware of the Public Health Service clinical practice guideline. Over 90% indicated that it was their role to prevent tobacco use; felt rewarded when they helped patients quit; and were bothered and upset by the health effects of tobacco. Doctors assisted more patients than nurses or dentists. Doctors and nurses reported more self-efficacy, motivation and preparedness for treating tobacco use than dentists. Providers with training performed more interventions and reported more self-efficacy, preparedness and fewer barriers than those without training. Training was associated with greater increases in self-efficacy, preparedness and intervention behaviours for dentists than for the other groups.

CONCLUSIONS

Despite a high prevalence of tobacco use and tobacco-related disease in Mississippi, primary care providers in Mississippi provide tobacco cessation interventions at an unacceptably low frequency relative to other regions. Training is likely to increase the frequency of intervention behaviours.

Determining the impact of Walk Kansas: applying a team-building approach to community physical activity promotion

BACKGROUND

Research and practice partnerships have the potential to enhance the translation of research findings into practice.

PURPOSE

This paper describes such a partnership in the development of Walk Kansas (WK) and highlights individual and organizational level outcomes.

METHOD

Phase 1 examined: (a) the reach of WK, (b) physical activity changes, and (c) maintenance of physical activity changes 6 months after the program was completed. Phase 2 explored WK adoption and sustainability over 5 years.

RESULTS

WK attracted a large number of participants who were more likely to be female, more active, and older than the adult population within the counties where they resided. Inactive or insufficiently active participants at baseline experienced significant increases in both moderate (p < 0.001) and vigorous (p < 0.001) physical activity. A random selection of participants who were assessed 6 months post-program did not demonstrate a significant decrease in moderate or vigorous activity between program completion and 6-month follow-up. The number of counties adopting the program increased across years, peaking at 97 in 2006 and demonstrated the sustainability of the WK over 5 years.

CONCLUSIONS

WK is effective, has a broad reach, and enables participants to maintain increased activity. It also shows promise for broad adoption and sustainability.

Enabling and sustaining the activities of lay health influencers: lessons from a community-based tobacco cessation intervention study

The authors present findings from a community-based tobacco cessation project that trained lay health influencers to conduct brief interventions. They outline four major lessons regarding sustainability. First, participants were concerned about the impact that promoting cessation might have on social relationships. "Social risk" must be addressed during training to ensure long-term sustainability. Second, formal training provided participants with an increased sense of self-efficacy, allowed them to embrace a health influencer identity, and aided in further reducing social risk. Third, material resources functioned to mediate social tensions during health intervention conversations. A variety of resources should be made available to health influencers to accommodate type of relationship, timing, and location of the interaction. Finally, project design must be attentive to the creation of a "community of practice" among health influencers as an integral part of project sustainability. These lessons have broad implications for successful health promotion beyond tobacco cessation.

What underlies appraisals? Experimentally testing a Knowledge-and-Appraisal Model of Personality Architecture among smokers contemplating high-risk situations

We tested a theoretical model of personality structures underlying patterns of intra-individual variability in contextualized appraisals. The KAPA (Knowledge-and-Appraisal Personality Architecture) model was tested experimentally among smokers appraising their efficacy to resist the urge to smoke in high-risk situations. In a novel design, we assessed self-knowledge and situational beliefs idiographically and employed cognitive priming to manipulate the accessibility of self-knowledge experimentally. The results confirmed the unique KAPA-model prediction that priming would affect appraisals in a contextualized manner. Priming positively valenced self-knowledge enhanced self-efficacy appraisals specifically within that subset of situations that were relevant to the primed knowledge. The results were consistent with the hypothesis that systems of self- and situational knowledge underlie consistency and variability in appraisals.

Lifetime characteristics of participants and non-participants in a smoking cessation trial: implications for external validity and public health impact

BACKGROUND

Detailed information about the characteristics of smokers who do and do not participate in smoking cessation treatment is needed to improve efforts to reach, motivate, and treat smokers.

PURPOSE

The aim of this study is to explore a broad range of characteristics related to participation in a smoking cessation trial.

METHODS

Eligible smokers were recruited from a longitudinal birth cohort. Participants and non-participants were compared on a broad range of sociodemographics, smoking, psychiatric and substance abuse disorders, personality, and prospective measures from early childhood. Eligible smokers were compared to a matched regional subsample of the Behavioral Risk Factor Surveillance System (BRFSS).

RESULTS

Few differences were observed, most of which were statistically significant but not clinically meaningful. Compared to non-participants, participants were more likely to be single, have lower income, be more nicotine-dependent, be more motivated to quit, and have higher levels of depressed mood and stress even after covariance of gender, income, and marital status. Sociodemographic differences between participants and the BRFSS sample reflect the skew toward lower socioeconomic status in the original birth cohort.

CONCLUSIONS

The encouraging conclusion is that smokers who enroll in cessation trials may not differ much from non-participants. Information about treatment participants can inform the development of recruitment strategies, improve the tailoring of treatment to individual smoker profiles, help to estimate potential selection bias, and improve estimates of population impact.

Olfactory and gustatory sensory changes to tobacco smoke in pregnant smokers

Models of smoking behavior change include addiction, social, and behavioral concepts. The purpose of this study was to explore the prevalence of two biologic factors, olfactory and gustatory responses to tobacco smoke, as potentially powerful contributors to smoking behavior change among pregnant women. Data were obtained from 209 pregnant smokers. The majority of women reported olfactory (62%) and gustatory (53%) aversions to tobacco. Aversions first appeared during the first trimester of pregnancy. Women who experienced olfactory aversions were more likely also to experience gustatory aversions. Olfactory aversions were associated with women smoking less. Aversions to tobacco smoke are common among pregnant smokers, are associated with women smoking less, and could help explain pregnant women's smoking patterns.

Campus physicians' tobacco interventions with university students: a descriptive study of 16 Ontario university clinics

OBJECTIVE

About one-quarter of Canadian post-secondary students smoke cigarettes. We examined how physicians from Ontario university health clinics intervene with these young adult smokers.

METHOD

A convenience sample of 16 universities was identified and surveys were hand-delivered to all 228 physicians from these schools. A total of 125 doctors (54.82%) responded; 70 were from universities that were involved in a government-sponsored, coordinated, multi-campus, tobacco control initiative.

RESULTS

Twenty percent of doctors reported asking all or almost all patients about tobacco use; 25.22% asked fewer than half. Describing how they respond to patients identified as smokers, 96.00% of physicians advised cessation, 72.00% offered assistance, and 64.00% arranged for follow-up. Doctors discussed patients' tobacco use with 78.59% of smokers. Nicotine replacement therapies were rarely offered to patients wanting to quit. Doctors from universities involved in the tobacco control initiative were more likely to keep patient education materials in the examining room.

CONCLUSION

Because most doctors ask only some patients about tobacco use, they may be missing opportunities to provide appropriate advice and assistance to all smokers.

PRACTICE IMPLICATIONS

Physician education and support to the clinic are needed to improve the frequency and quality of physician-delivered smoking cessation services to post-secondary students.

Impact of a statewide Internet-based tobacco cessation intervention

Background

An increasing number of people have access to the Internet, and more people are seeking tobacco cessation resources online every year. Despite the proliferation of various online interventions and their evident acceptance and reach, little research has addressed their impact in the real world. Typically, low response rates to Internet-based follow-up surveys generate unrepresentative samples and large confidence intervals when reporting results.

Objectives

The aim of this study was to achieve a high response rate on follow-up evaluation in order to better determine the impact of an Internet-based tobacco cessation intervention provided to tobacco users in Minnesota, United States.

Methods

Participants included 607 men and women aged 18 and over residing in Minnesota who self-reported current tobacco use when registering for an Internet-based tobacco cessation program between February 2 and April 13, 2004. Participants were given access to an interactive website with features including social support, expert systems, proactive email, chat sessions, and online counselors. Mixed-mode follow-up (online survey with telephone survey for online nonrespondents) occurred 6 months after registration.

Results

Of the study participants, 77.6% (471/607) responded to the 6-month follow-up survey (39.4% online and 38.2% by telephone). Among respondents, 17.0% (80/471, 95% CI = 13.6%-20.4%) reported that they had not smoked in the past 7 days (observed rate). Assuming all nonrespondents were still smoking (missing=smoking rate), the quit rate was 13.2% (80/607, 95% CI = 10.5%-15.9%).

Conclusions

This mixed-mode follow-up survey of an online smoking cessation program achieved a high response rate and provides a more accurate estimate of long-term cessation rates than has been previously reported. Quit rates for the Internet-based tobacco cessation program were higher than those expected for unassisted quit attempts and are comparable to other evidence-based behavioral interventions. The similarities between quit rates demonstrates that an Internet-based cessation program may have as great an impact as, and can have wider reach than, other cessation programs such as those delivered by telephone. With over 100000 people having visited the website and over 23000 having registered, a 6-month self-reported quit rate of 13.2% suggests that the quitplan.com program helped over 3000 Minnesotans remain tobacco free for at least 6 months. Results of this study suggest that an Internet-based cessation program is a useful tool in states’ efforts to provide comprehensive cessation tools for smokers.

Effectiveness of an Internet-Based Worksite Smoking Cessation Intervention at 12 Months

OBJECTIVE

To evaluate effectiveness of an Internet-based smoking cessation program as part of a comprehensive health risk reduction initiative in a large, geographically dispersed employee population.

METHODS

A financial incentive for participation was offered during 2003 health benefits enrollment. The primary cessation outcome was 7-day point prevalence abstinence at 12 months.

RESULTS

A total of 1776 employees used the Internet program. Among those surveyed, the response rate was 32%. Quit rates ranged from 13% using intention to treat analysis (nonresponders counted as smokers) to 43% among survey responders. Higher Web site utilization was associated with better cessation outcomes, even after controlling for baseline motivation.

CONCLUSIONS

The Internet program was successful at reaching a large number of geographically dispersed employees. The range of quit rates suggests that Internet cessation programs can be effective in promoting cessation and preventing relapse in a worksite setting.

Characteristics of smokers reached and recruited to an internet smoking cessation trial: a case of denominators

The Internet can deliver smoking cessation interventions to large numbers of smokers. Little is known about the feasibility, reach, or efficacy of Internet cessation interventions. Virtually no data exist on who enrolls in cessation programs or on differences between those who complete enrollment and those who do not. This paper reports recruitment and enrollment findings for the first 764 participants in an ongoing randomized controlled trial that tested the efficacy of a widely disseminated Internet smoking cessation service (www.QuitNet.com) alone and in conjunction with telephone counseling. Study participants were recruited through Internet search engines using an active user sampling protocol. During the first 16 weeks of the study, 28,297 individuals were invited. Of those, 11,147 accepted the invitation, 5,557 screened eligible, 3,614 were recruited, 1,489 provided online informed consent, and 764 were confirmed eligible and enrolled. Of those who were at least curious about a cessation trial (n= 11,147), 6.9% enrolled. Of those who were eligible and recruited (n=3,614), 21.1% enrolled. Depending on the denominator selected, results suggest that 7% to 21% of smokers interested in cessation will enroll into a research trial. Internet recruitment provides unique challenges and opportunities for managing sample recruitment, analyzing subsamples to determine generalizability, and understanding the characteristics of individuals who participate in online research.

The future of tobacco-control research

Recent epidemiologic data on the stabilization of adult and youth smoking rates underscore the need for vigorous research across the cancer control spectrum on tobacco use interventions. The steady decline in adult rates of smoking has stalled for the first time in 8 years, and certain race, ethnic, and population groups are disproportionately at risk to tobacco-related cancers because of disparities in tobacco use or access to effective interventions. Although substantial progress has been made across levels of basic through applied research, tobacco-control research across the discovery and delivery continuum must be accelerated to further reduce the cancer burden. Following a brief review of the prevalence and trends affecting tobacco use initiation and cessation, we identify and describe four domains of extraordinary research opportunities: genetics and gene-environment interactions, bioinformatics and health informatics, disparities and disproportionate risk, and prevention and treatment. Evolutionary scientific changes, like rapidly advancing technology and emphasis on the paradigm of team science research approaches, provide both a challenge as well as unparalleled opportunities for scientific advancement and public health progress.

Step into Motion: a randomized trial examining the relative efficacy of Internet vs. print-based physical activity interventions

Over two-thirds of Americans access the Internet and therefore, the Internet may be an important channel for reaching the large population of sedentary individuals. The purpose of this paper is to describe the methods for a randomized controlled trial examining the efficacy of an Internet-based physical activity intervention relative to a print intervention that has been shown to be effective in previous trials. Specifically, 249 sedentary participants were randomized to receive one of three interventions: 1) Internet-based motivationally-tailored individualized feedback (Tailored Internet); 2) print-based motivationally-tailored individualized feedback (Tailored Print); or 3) physical activity websites currently available to the public (Standard Internet). Participants completed the 7-Day Physical Activity Recall interview, wore an objective physical activity monitor (i.e., ActiGraph), and participated in a treadmill fitness test at baseline, 6, and 12 months. The sample consisted of mostly women (84.2%) and Caucasian individuals (76.4%) who reported exercising an average of 21 min per week at baseline. This is the first study that we are aware of, that has examined the efficacy of a tailored Internet-based physical activity intervention. This study will have implications for the dissemination of Internet-based physical activity interventions.

eHealth evaluation and dissemination research

This paper reviews key challenges in evaluating eHealth intervention and behavior change programs, and makes recommendations for the types of designs, measures, and methods needed to accelerate the integration of proven eHealth programs into practice. Key issues discussed include evaluation approaches that answer questions that consumers, potential adoptees, and policymakers have. These include measures of participation and representativeness at both patient and healthcare setting levels, consistency of outcomes across different subgroups, tendency of an eHealth program to ameliorate versus exacerbate health disparities, implementation and program adaptation, cost, and quality-of-life outcomes. More practical eHealth trials are needed that use rigorous but creative designs compatible with eHealth interventions and theory. These evaluations should address key dissemination issues, such as appeal, use, and robustness of eHealth programs across different subgroups, settings, conditions, outcomes, and time.

Beyond effectiveness: evaluating the public health impact of the WISEWOMAN program

Interventions that are effective are often improperly or only partially implemented when put into practice. When intervention programs are evaluated, feasibility of implementation and effectiveness need to be examined. Reach, effectiveness, adoption, implementation, and maintenance make up the RE-AIM framework used to assess such programs. To examine the usefulness of this metric, we addressed 2 key research questions. Is it feasible to operationalize the RE-AIM framework using women's health program data? How does the determination of a successful program differ if the criterion is (1) effectiveness alone, (2) reach and effectiveness, or (3) the 5 dimensions of the RE-AIM framework? Findings indicate that it is feasible to operationalize the RE-AIM concepts and that RE-AIM may provide a richer measure of contextual factors for program success compared with other evaluation approaches.

Controlled study of brief personalized assessment-feedback for drinkers interested in self-help

AIMS

Brief alcohol interventions typically have been directed to heavy-drinking patients seeking primary health care and college students. This study examined the efficacy of mailing brief personalized assessment-feedback to interested drinkers recruited from the general public. We hypothesized that problem drinkers would benefit more from the intervention than individuals who were not problem drinkers.

DESIGN

A two-arm, double-blinded, community-based randomized controlled trial with 6-month follow-up.

SETTING AND PARTICIPANTS

A screening interview was administered to a stratified random sample of 10 014 Canadians 18 years of age and older (5621 women and 4393 men; M age = 43.3 years, SD = 15.99; response rate = 65.4%).

INTERVENTION

Current drinkers interested in receiving alcohol self-help materials (n = 1727) were assigned randomly to receive brief personalized assessment-feedback on male and female population drinking norms by mail, or to a delayed-treatment control group, and were contacted 6 months later (76% retention rate).

MEASUREMENTS

Problem drinking status at baseline [using sex-specific Alcohol Use Disorders Identification Test (AUDIT) cut scores], and frequency and quantity of alcohol use at follow-up.

FINDINGS

Analysis of covariance identified the hypothesized interaction of baseline problem drinking status and treatment condition (P < 0.01). Among problem drinkers identified at baseline the intervention caused a 10.1% reduction in per-occasion binge drinking compared to controls, whereas there was no difference in binge drinking across conditions for non-problem drinkers.

CONCLUSIONS

The continuum of care for alcohol problems can be broadened by providing brief interventions to interested drinkers in the general population.

Outcomes from the women's wellness project: a community-focused physical activity trial for women

BACKGROUND

Given the low rates of physical activity participation, innovative intervention approaches are needed to make a public health impact.

METHODS

The study was conducted at the Miriam Hospital/Brown Medical School in Providence, RI, and in communities of Southeastern Massachusetts from 2002 to 2005. Previously sedentary women (n = 280; mean age = 47.1; 94.6% Caucasian) were randomly assigned to one of three conditions: (1) Choose to Move, a self-help printed booklet (n = 93), (2) Jumpstart, a motivationally tailored, print based intervention (n = 95); or (3) Wellness, women's health materials (n = 92). Face-to-face contact at months 3 (M3) and 12 (M12) occurred within participants' communities in local libraries.

RESULTS

At M3, participants in the Jumpstart condition reported significantly more minutes of physical activity per week (M = 140.4, SE = 14.82) than participants in the Wellness condition (M = 98.1, SE = 15.09), (t(275) = 2.00, p < 0.05). The Jumpstart arm showed a trend towards significance (t(275) = 1.93, p = 0.054) when compared with the CTM arm (M = 99.5, SE = 15.11); there was no significant difference between the CTM and Wellness arms (t(275) = 0.07, p = NS). At M12, there were no significant differences (F(2,275) = 0.147, p = NS) between any of the treatment arms.

CONCLUSIONS

Results suggest that print-based programs for physical activity may be efficacious short-term, but more research is needed to find approaches that are effective long-term. It is possible to deliver print-based programs through existing community infrastructures, however these approaches need further evaluation to examine maintenance effects apart from the demand characteristics of a research study.

Tailored communications for smoking cessation: past successes and future directions

Tailored communications are one of the most promising approaches to smoking cessation interventions for entire populations. Assessments based on the Transtheoretical Model are processed by computer-based expert systems that generate feedback reports tailored to each individual to accelerate their progress through the stages of change for smoking cessation. Seven studies are reviewed that range from a more traditional clinical trial to trials on entire populations of smokers to population trials designed to change multiple behaviours, including smoking. A series of three tailored communications was found to produce long-term point prevalence abstinence rates within the narrow range of 22-26% abstinence. This same range of abstinence was found even when two or three other behaviours (e.g. diet and sun protection) were treated in the population. These results point to a future in which health behaviour risk interventions will be assessed not solely by their efficacy but by their population impact.

Characterizing Internet searchers of smoking cessation information

BACKGROUND

The Internet is a viable channel to deliver evidence-based smoking cessation treatment that has the potential to make a large population impact on reducing smoking prevalence. There is high demand for smoking cessation information and support on the Internet. Approximately 7% (10.2 million) of adult American Internet users have searched for information on quitting smoking. Little is known about these individuals, their smoking status, what type of cessation services they are seeking on the Internet, or how frequently these searches for cessation information are conducted.

OBJECTIVE

The primary goal of this study was to characterize individuals who search for smoking cessation information on the Internet to determine appropriate triage and treatment strategies. The secondary goal was to estimate the incidence of searches for cessation information using publicly available search engine data.

METHODS

We recruited individuals who clicked on a link to a leading smoking cessation website (QuitNet) from within the results of a search engine query. Individuals were "intercepted" before seeing the QuitNet home page and were invited to participate in the study. Those accepting the invitation were routed to an online survey about demographics, smoking characteristics, preferences for specific cessation services, and Internet search patterns. To determine the generalizability of our sample, national datasets on search engine usage patterns, market share, and keyword rankings were examined. These datasets were then used to estimate the number of queries for smoking cessation information each year.

RESULTS

During the 10-day study period, 2265 individuals were recruited and 29% (N = 655) responded. Of these, 59% were female and overall tended to be younger than the previously characterized general Internet population. Most (76%) respondents were current smokers; 17% had quit within the last 7 days, and 7% had quit more than 7 days ago. Slightly more than half of active smokers (53%) indicated that they were planning to quit in the next 30 days. Smokers were more likely to seek information on how to quit and on medications; former smokers were more interested in how to cope with withdrawal. All participants rated withdrawal information and individually tailored information as being more useful, while displaying little interest in telephone counseling, expert support, or peer support. Publicly available data from large search engines suggest that 4 million Americans search for resources on smoking cessation each year.

CONCLUSIONS

This study adds to the limited data available on individuals who search for smoking cessation information on the Internet, supports the prior estimates of the size of the population, and indicates that these individuals are in appropriate stages for both active cessation interventions and aggressive relapse prevention efforts. Continued development and evaluation of online interventions is warranted, and organizations seeking to promote cessation should carefully evaluate the Internet as a possible modality for treatment and as a gateway to other traditional programs.

Smoking cessation treatment by primary care physicians: An update and call for training

BACKGROUND

Public health and government organizations have invested considerably to increase physician adherence to smoking-cessation practice guidelines.

METHODS

A random sample of 2000 U.S. primary care physicians was ascertained from the American Medical Association (AMA) in 2002. Respondents (n = 1120, 62.3%) provided self-reported data about individual and practice characteristics and smoking-cessation practices. Data were analyzed in 2005.

RESULTS

Most primary care physicians (75%) advised cessation, 64% recommended nicotine patches, 67% recommended bupropion, 32% recommended nicotine gum, 10% referred to cessation experts, and 26% referred to cessation programs "often or always." Advising cessation was related to being older, having a faculty appointment, having trained staff for smoking counseling, and having confidence to counsel patients about smoking. Physicians who were internists, younger, and those with greater confidence to counsel patients about smoking recommended nicotine replacement more often. Prescribing bupropion was less common among older physicians, in the Northeast, with trained staff available for counseling, and with a greater proportion of minority or Medicaid patients. Prescribing bupropion was more common among AMA-member physicians and physicians with greater confidence to counsel patients about smoking. Providing a referral to an outside expert or program was more common among female physicians, and physicians in the Northeast or West, with larger clinical practices, and with trained staff for cessation counseling.

CONCLUSIONS

Current physician self-reported practices for smoking cessation suggest opportunity for improvement. Targeted efforts to educate and support subsets of primary care physicians may improve physician adherence and smoking outcomes.

Interest in an online smoking cessation program and effective recruitment strategies: results from Project Quit

Background

The Internet is a promising venue for delivering smoking cessation treatment, either as a stand-alone program or as an adjunct to pharmacotherapy. However, there is little data to indicate what percent of smokers are interested in receiving online smoking cessation services or how best to recruit smokers to Internet-based programs.

Objective

Using a defined recruitment sample, this study aimed to identify the percentage of smokers who expressed interest in or enrolled in Project Quit, a tailored, online, cognitive-behavioral support program offered with adjunctive nicotine replacement therapy patches. In addition, we examined the effectiveness of several individual-level versus population-level recruitment strategies.

Methods

Members from two large health care organizations in the United States were invited to participate in Project Quit. Recruitment efforts included proactive invitation letters mailed to 34533 likely smokers and reactive population-level study advertisements targeted to all health plan members (> 560000 adults, including an estimated 98000 smokers across both health care organizations).

Results

An estimated 1.6% and 2.5% of adult smokers from each health care organization enrolled in Project Quit. Among likely smokers who received proactive study invitations, 7% visited the Project Quit website (n = 2260) and 4% (n = 1273) were eligible and enrolled. Response rates were similar across sites, despite using different sources to assemble the invitation mailing list. Proactive individual-level recruitment was more effective than other forms of recruitment, accounting for 69% of website visitors and 68% of enrollees.

Conclusions

Smokers were interested in receiving online smoking cessation support, even though they had access to other forms of treatment through their health insurance. Uptake rates for this program were comparable to those seen when smokers are advised to quit and are referred to other forms of smoking cessation treatment. In this sample, proactive mailings were the best method for recruiting smokers to Project Quit.

A model for postpartum smoking resumption prevention for women who stop smoking while pregnant

Behavior change models and theories have been useful in our efforts to help people stop smoking. However, models that were developed for the general population do not always fit special populations such as pregnant women. Many women stop smoking while pregnant, but most resume smoking after giving birth. To help women who stop smoking while pregnant to stay smoke-free, a model for tailoring a smoking resumption-prevention intervention to the special needs of pregnant and postpartum women is proposed. The intervention begins during pregnancy, continues postpartum, and addresses pregnancy and parenting contextual factors in women's lives. The model is based on motivational theory and includes conducting patient assessments, developing risk profiles, triaging women to different levels of intervention intensity, and matching intervention strategies to women's risk profiles.

Innovations in population intervention research capacity: the contributions of Canada on the Move

The Canada on the Move project developed within a dynamic context and in response to an expressed need for increased capacity to support research involving population-level interventions. This article describes a) the movement to create an organized approach to chronic disease prevention in Canada, b) the emerging science of population-level intervention, c) the development of Canadian infrastructure to support population intervention science, and d) the contribution of Canada on the Move in developing a health research platform and, opportunistically, instigating a study which included assessment of the population impact of a commercial marketing initiative.

Applying Transdisciplinary Research Strategies to Understanding and Eliminating Health Disparities

This overview for the special issue of Health Education & Behavior on “Health Disparities and Social Inequities” briefly outlines the transdisciplinary (TD) approach to research and examines the scope of TD science. The need to embrace basic science as well as several domains of applied research is discussed along the TD “pipeline” from discovery to development to delivery to policy. The overview concludes with selected examples of the emerging TD science of disparities. One central challenge for a TD approach is the need to strengthen what is being called “the science of dissemination” along with improving the “dissemination of evidence-based science.”

Evaluating the relevance, generalization, and applicability of research: issues in external validation and translation methodology

Starting with the proposition that "if we want more evidence-based practice, we need more practice-based evidence," this article (a) offers questions and guides that practitioners, program planners, and policy makers can use to determine the applicability of evidence to situations and populations other than those in which the evidence was produced (generalizability), (b) suggests criteria that reviewers can use to evaluate external validity and potential for generalization, and (c) recommends procedures that practitioners and program planners can use to adapt evidence-based interventions and integrate them with evidence on the population and setting characteristics, theory, and experience into locally appropriate programs. The development and application in tandem of such questions, guides, criteria, and procedures can be a step toward increasing the relevance of research for decision making and should support the creation and reporting of more practice-based research having high external validity.

Do behavioral smoking reduction approaches reach more or different smokers? Two studies; similar answers

There is a need for innovative approaches capable of reaching smokers who would not otherwise participate in efforts to modify their smoking. This paper reports on two studies to determine whether a smoking reduction intervention would appeal to additional or different types of smokers than do cessation interventions. Study 1 attempted to contact 160 HMO smokers scheduled for outpatient surgeries. In Study 2, actual pilot reduction and cessation programs were offered to 531 smokers about to undergo out-patient surgeries or procedures. In Study 1, 39% of those eligible elected smoking reduction; and 38% selected cessation. In Study 2 of those eligible, 22% began participation in the smoking reduction program; 12% preferred a cessation approach; and 65% declined. There were few demographic or smoking history differences among those who elected smoking reduction, cessation, or declined. Among this understudied population, a sizable proportion in both studies agreed to participate in smoking reduction. If replicated, this suggests that comprehensive programs that include a smoking reduction component could substantially increase their reach.

Integration and coordination of pain management in primary care

Pain is one of the most common symptoms reported to primary care providers and has significant implications for health care costs. The primary aim of this article is to describe and illustrate how to integrate the treatment of chronic pain in the primary care setting. First, we address the integration and coordination of care between mental health and primary care. We then present a typical case and discuss the patient's treatment, outcome, and prognosis. The article concludes with a discussion of issues that frequently arise when integrating psychological treatment for pain in primary care settings.

Home health care nurses as a new channel for smoking cessation treatment: outcomes from project CARES (Community-nurse Assisted Research and Education on Smoking)

BACKGROUND

Clinical guidelines for smoking cessation may not be sufficient for helping some subgroups of smokers quit. Incorporating smoking cessation into home-based medical care can proactively reach high-risk smokers who may not have access to (or spontaneously seek) smoking cessation.

METHOD

Home health care nurses (N = 98) were randomly assigned to deliver either Motivational Enhancement (ME; Motivational Interviewing + Carbon Monoxide Feedback) or Standard Care (AHCPR Guidelines for smoking cessation) to their patients. Seventy percent of patients were eligible and willing to participate (N = 273; 54% female, mean age = 57 years, 83% Caucasian, 41% < high school education). The study was conducted in Providence, RI, USA from 1998 to 2003.

RESULTS

Biochemically verified continuous abstinence rates at the 12-month follow-up were 4.2% (SC) and 8.7% (ME) for intent to treat analyses, and 5.2% (SC) and 11.8% (ME) using all available cases (P > 0.05). ME reported more quit attempts and significantly greater reductions in the number of cigarettes smoked per day at all follow-ups through 12 months of post-treatment (all P values < 0.05).

CONCLUSIONS

Use of an existing public health channel such as home health care to reach smokers who vary in their motivation to quit could have the potential for large public health impact.

Comparing participants and nonparticipants recruited for an effectiveness study of nicotine replacement therapy

BACKGROUND

Interventions for smoking cessation have been typically evaluated on reactively recruited samples in clinical trials (efficacy trials). However, to have an impact on smoking rates in a general population, the intervention should also be evaluated with proactively recruited representative samples (effectiveness trials).

PURPOSE

The characteristics of participants and two groups of nonparticipants recruited for a population-based nicotine replacement therapy study were compared.

METHODS

All members of a large New England Veterans' Administration Medical Center were contacted, and interviews were completed with 3,239 identified smokers (at least 10 cigarettes per day). At the end of the interview, all smokers were offered participation in a multiple intervention study. Of the interviewed smokers, 2,915 verbally agreed to participate in the study (90%). Of those who gave initial verbal consent, 2,054 returned the written informed consent form and became participants (70%).

RESULTS

The participants (full consent group) differed significantly from both nonparticipant groups-that is, the smokers who were interviewed but declined participation by active refusal (survey only group) and those who gave verbal consent but passively refused participation by failing to return the written consent form (verbal consent only group). Participants were more likely to be married, younger, and female; to live with others; and to have previously used or considered using nicotine replacement therapy. The survey only group was also more likely to be in the precontemplation stage (54%), whereas the participants were more likely to be in the contemplation (46%) or preparation stage (35%). The verbal consent only group was intermediate of the other two groups in stage-of-change characteristics.

CONCLUSIONS

An important finding was that it is possible to recruit a large proportion of a sample of identified smokers to an nicotine replacement therapy study. However, the participants are likely to differ in significant ways from those who either actively or passively decline participation.

Beginning with the application in mind: designing and planning health behavior change interventions to enhance dissemination

Failing to retain an adequate number of study participants in behavioral intervention trials poses a threat to interpretation of study results and its external validity. This qualitative investigation describes the retention strategies promoted by the recruitment and retention committee of the Behavior Change Consortium, a group of 15 university-based sites funded by the National Institutes of Health to implement studies targeted toward disease prevention through behavior change. During biannual meetings, focus groups were conducted with all sites to determine barriers encountered in retaining study participants and strategies employed to address these barriers. All of the retention strategies reported were combined into 8 thematic retention categories. Those categories perceived to be most effective for retaining study participants were summarized and consistencies noted among site populations across the life course (e.g., older adults, adults, children, and adolescents). Further, possible discrepancies between site populations of varying health statuses are discussed, and an ecological framework is proposed for use in future investigations on retention.

The effectiveness of a nursing inpatient smoking cessation program in individuals with cardiovascular disease

BACKGROUND

Smoking is an important risk factor for cardiovascular disease (CVD), and quitting is highly beneficial. Yet, less than 30% of CVD patients stop smoking. Relapse-prevention strategies seem most effective when initiated during the exacerbation of the disease.

OBJECTIVE

A nurse-delivered inpatient smoking cessation program based on the Transtheoretical Model with telephone follow-up tailored to levels of readiness to quit smoking was evaluated on smoking abstinence and progress to ulterior stages of change.

METHOD

Participants (N = 168) were randomly assigned by cohorts to inpatient counseling with telephone follow-up, inpatient counseling, and usual care. The inpatient intervention consisted of a 1-hr counseling session, and the telephone follow-up included 6 calls during the first 2 months after discharge. The nursing intervention was tailored to the individual's stage of change. End points at 2 and 6 months included actual and continuous smoking cessation rates (biochemical markers) and increased motivation (progress to ulterior stages of change).

RESULTS

Assuming that surviving patients lost to follow-up were smokers, the 6-month smoking abstinence rate was 41.5% in the inpatient counseling with telephone follow-up group, compared with 30.2% and 20% in the inpatient counseling and usual care groups, respectively (p = .05). Progress to ulterior stages of change was 43.3%, 32.1%, and 18.2%, respectively (p = .02). Stage of change at baseline and intervention predicted smoking status at 6 months.

DISCUSSION

This tailored smoking cessation program with telephone follow-up significantly increased smoking cessation at 6 months, and progression to ulterior stages of change. The telephone follow-up was an important adjunct. It is, therefore, recommended to include such comprehensive smoking cessation programs within hospital settings for individuals with CVD.

Reducing the cancer burden of lifestyle factors: opportunities and challenges of the Internet

This paper focuses on the Internet as a tool for enhancing behavior and lifestyle changes to reduce the burden of cancer at a population level. The premise of this paper is that the Internet can and should be leveraged to bridge the chasm between basic science, clinical trials, and public health. Our focus is specifically on the opportunity to disseminate effective behavioral science interventions via the Internet in order to decrease the prevalence of behavioral risk factors for cancer. The examples herein are primarily drawn from tobacco use to illustrate issues that can be applied more generally to other behavioral risk factors for cancer. Four areas will be addressed: (1) the scientific basis and rationale for delivering lifestyle behavior change interventions via the Internet; (2) the need to determine the quality of Internet interventions; (3) methodological considerations in conducting evaluations of Internet interventions; and (4) recommendations for a transdisciplinary approach to Internet intervention development and evaluation.

Initial evaluation of a real-world Internet smoking cessation system

To significantly reduce smoking prevalence, treatments must balance reach, efficacy, and cost. The Internet can reach millions of smokers cost-effectively. Many cessation Web sites exist, but few have been evaluated. As a result, the potential impact of the Internet on smoking prevalence remains unknown. The present study reports the results, challenges, and limitations of a preliminary, large-scale evaluation of a broadly disseminated smoking cessation Web site used worldwide (QuitNet). Consecutive registrants (N=1,501) were surveyed 3 months after they registered on the Web site to assess 7-day point prevalence abstinence. Results must be interpreted cautiously because this is an uncontrolled study with a 25.6% response rate. Approximately 30% of those surveyed indicated they had already quit smoking at registration. Excluding these participants, an intention-to-treat analysis yielded 7% point prevalence abstinence (for the responders only, abstinence was 30%). A range of plausible cessation outcomes (9.8%-13.1%) among various subgroups is presented to illustrate the strengths and limitations of conducting Web-based evaluations, and the tensions between clinical and dissemination research methods. Process-to-outcome analyses indicated that sustained use of QuitNet, especially the use of social support, was associated with more than three times greater point prevalence abstinence and more than four times greater continuous abstinence. Despite its limitations, the present study provides useful information about the potential efficacy, challenging design and methodological issues, process-to-outcome mechanisms of action, and potential public health impact of Internet-based behavior change programs for smoking cessation.

Disseminating a Smokeless Tobacco Cessation Intervention Model to Dental Hygienists: A Randomized Comparison of Personalized Instruction and Self-Study Methods

This study evaluated 2 methods of disseminating an empirically validated smokeless tobacco intervention delivered during routine dental care. Twenty cities within 12 states were stratified and then randomized to 1 of 3 groups: personalized instruction (PI), self-study (SS), or delayed training (DT) control. Dental hygienists in the SS condition were sent a manual and video. Those in the PI condition were recruited to attend a workshop. Thirty-seven percent of eligible hygienists agreed to participate. At 12 months postenrollment, hygienists in the SS and PI conditions significantly increased their "Assist" behaviors (discuss cessation techniques, help patient set a quit date, and provide cessation materials) and reported fewer perceived barriers to delivering the intervention as compared with hygienists in DT. An economic analysis suggests that SS is more cost-effective than PI.

Stepped care in psychological therapies: access, effectiveness and efficiency. Narrative literature review

BACKGROUND

There is a significant gap between the demand for psychological therapy services and the available supply. One proposal to overcome this problem is to increase efficiency of provision through the adoption of briefer 'minimal interventions' within stepped care models.

AIMS

To examine the theoretical underpinnings of stepped care, together with the practicalities of the adoption of this system of care.

METHOD

Narrative literature review.

RESULTS

The potential clinical and economic benefits of stepped care are dependent upon underlying assumptions of equivalence in terms of clinical outcomes, efficiency in terms of resource use and costs, and acceptability of 'minimal interventions' to patients and therapists. Illustrative studies of these issues are considered.

CONCLUSIONS

Although psychological services might benefit from the adoption of the stepped care model, a substantial research agenda needs to be fulfilled before a judgement can be made as to whether stepped care might be an efficient method of delivering psychological services.

Disseminating effective cancer screening interventions

A large gap exists between the results of research concerning efficacious cancer screening programs and the programs delivered in practice. In this article, the authors discuss issues in, barriers to, and lessons learned regarding the dissemination of interventions. They summarize previous reviews, exemplary studies, and theories regarding the diffusion and dissemination of cancer screening interventions. Six lessons learned address the involvement of key stakeholders, factors influencing diffusion, the need for different types of efficacy and effectiveness studies with greater attention to external validity, replication, the use of theoretical and evaluation models, and the importance of policy infrastructure. In this article, the authors make recommendations for future research and practice, including improving the understanding of the intervention process and changing the types of grants funded and review criteria used. Also needed are an enhanced infrastructure, including policies to support dissemination, and the involvement of researchers, health care administrators, clinicians, and funding organizations in dissemination if the gap between research and practice in cancer screening is to be reduced.

Best practice in group-based smoking cessation: results of a literature review applying effectiveness, plausibility, and practicality criteria

OBJECTIVE

Apply a "best practices" model to evidence regarding group smoking cessation to inform organizational decisions about adopting such programs. The best-practices model attempts to integrate rigorous review of evidence with context and practical considerations important to organizations contemplating adoption.

DATA SOURCES

First, we identified effective practices by systematic literature review with two blinded reviewers to (1) search databases (99.8% agreement), (2) hand search journals with five or more papers selected in first step (99.9% agreement), (3) search reference lists of included papers (99.4% agreement), and (4) contact published experts. Second, model programs, theory, and expert opinion suggested plausible practices. Finally, a practitioner-researcher advisory group suggested practical considerations affecting adoption decisions.

STUDY SELECTION

All 67 studies included in the review met six requirements: (1) peer reviewed, (2) primary studies, (3) using experimental or quasi-experimental design, (4) compared one or more smoking-cessation interventions that involved two or more group sessions, (5) studied persons 18+ years old, and (6) reported > or =6-month point prevalence or continuous abstinence outcomes.

DATA EXTRACTION

Two independent raters assessed study quality (89.5% agreement). Effective practices consistently exhibited a statistically significant effect. Plausible practices showed consistency across three types of evidence. An advisory group based practicality criteria on critical review and experience.

DATA SYNTHESIS

Two practices were rated effective: multicomponent behavioral intervention and nicotine replacement therapy. Five practices received plausible ratings: components of behavioral skills, information about smoking, self-monitoring, social support, and four or more sessions of 60 to 90 minutes. The Advisory Group identified 11 practicality questions to assist organizations to make adoption decisions regarding effective and plausible practices.

CONCLUSIONS

No research evidence guides potential smoking-cessation program adopters regarding program participants, providers, settings, or quality assurance. Reviews to influence practice must consider science and practice (context) to facilitate adoption of best practices.

Multiple behavioral risk factor interventions in primary care. Summary of research evidence

BACKGROUND

An important barrier to the delivery of health behavior change interventions in primary care settings is the lack of an integrated screening and intervention approach that can cut across multiple risk factors and help clinicians and patients to address these risks in an efficient and productive manner.

METHODS

We review the evidence for interventions that separately address lack of physical activity, an unhealthy diet, obesity, cigarette smoking, and risky/harmful alcohol use, and evidence for interventions that address multiple behavioral risks drawn primarily from the cardiovascular and diabetes literature.

RESULTS

There is evidence for the efficacy of interventions to reduce smoking and risky/harmful alcohol use in unselected patients, and evidence for the efficacy of medium- to high-intensity dietary counseling by specially trained clinicians in high-risk patients. There is fair to good evidence for moderate, sustained weight loss in obese patients receiving high-intensity counseling, but insufficient evidence regarding weight loss interventions in nonobese adults. Evidence for the efficacy of physical activity interventions is limited. Large gaps remain in our knowledge about the efficacy of interventions to address multiple behavioral risk factors in primary care.

CONCLUSIONS

We derive several principles and strategies for delivering behavioral risk factor interventions in primary care from the research literature. These principles can be linked to the "5A's" construct (assess, advise, agree, assist, and arrange-follow up) to provide a unifying conceptual framework for describing, delivering, and evaluating health behavioral counseling interventions in primary healthcare settings. We also provide recommendations for future research.

Alcohol problems and interest in self-help: a population study of Alberta adults

BACKGROUND

We quantified the prevalence of alcohol problems among Alberta adults and determined relationships between sociodemographic characteristics, problem drinking status, and interest in self-help materials to reduce alcohol use.

METHODS

A computer-aided telephone interview was administered to a stratified random sample of 10,014 Albertans, 18 years of age or older (5,621 women and 4,393 men; M age = 43.3 years, SD = 16.0), with a response rate of 65.4%. Measures included: 1) current drinking status, 2) prior alcohol treatment, 3) problem drinking status (using the Alcohol Use Disorders Identification Test; AUDIT), and 4) interest in receiving free self-help materials to encourage safe drinking. Data were weighted to reflect age, sex, and regional Alberta population.

RESULTS

Of the total sample, 19.3% abstained from drinking in the past year, 4.2% had received treatment for alcohol problems at some point in their lives, and 80.7% were current drinkers (i.e., consumed alcohol in the previous year). Some 15.2% (n = 1,193) of current drinkers were classified as having a drinking problem. Logistic regression analyses showed that problem drinkers had 3.5 times greater odds of being male and 2.3 times greater odds of being interested in self-help interventions, compared to other current drinkers. Being single, of younger age, and not being exposed to post-secondary education also significantly predicted problem drinking status.

INTERPRETATION

Alcohol misuse is common among Alberta drinkers, but many of them are interested in receiving brief public health interventions designed to help them assert control over their behaviour.

Development of Web-based intervention system for periodontal health: a pilot study in the workplace

BACKGROUND

It has recently been accepted that periodontal disease is a risk factor for not only tooth loss but also systemic diseases. An effective system of public intervention for periodontal health to enable continuous intervention of dental professionals has been sought. We developed a Web-based intervention system regarding periodontal health and evaluated the effects of the system in the workplace.

METHODS

The system was capable of storage and display of personalized oral health records including video images pertaining to toothbrush manipulation within their own oral cavities based on instructions by dental professionals. The system enabled clients to view movement of their own skill, and repeatedly. Thirteen workers of a company were randomized to either an experimental or control group. The control group received face-to-face toothbrushing instruction at the company and follow-up via telephone. The experimental group received follow-up through our system in addition to those components employed in the control group.

MAIN RESULTS

The workers in the experimental group benefited in terms of improvements of not only plaque removal but also periodontal health over 3 months.

CONCLUSIONS

These results indicate that implementation of an Web-based approach for periodontal health affords the possibility of remote instruction and produces additional public benefit.

Smoking Cessation Research in Primary Care Treatment Centers: The SCRIPT-MS Project

Despite wide distribution of an evidence-based clinical practice guideline, the provision of treatment for tobacco use has been weak. The primary care setting is an ideal environment in which to implement the tobacco clinical practice guideline. It has been suggested that implementation of the guideline may be enhanced by adapting guideline recommendations into a stepped-care plus treatment-matching model; however, this model has yet to be tested. This article describes an ongoing investigation designed to evaluate (1) the feasibility of implementing this treatment model in a primary care environment, (2) efforts on identifying reasonable assessment methods, (3) primary care providers' use of assessment data, and (4) the relationships between predictors and outcomes under differing treatment "step" conditions in primary care settings. Six primary care clinics are participating in this study comparing usual care, brief clinical intervention, and enhanced clinical intervention conditions. The last of these conditions is hypothesized to produce the best and most cost-effective outcomes. Recruitment is expected to continue until January 2004, being 65% complete as of this writing. Follow-up contacts will continue until April 2005. Results should provide information that will contribute to the ongoing development of primary care-based tobacco intervention approaches.

Healthcare Provider Training in Tobacco Treatment: Building Competency

One of the most effective disease prevention and health promotion strategies available is the treatment of tobacco dependence. The Agency for Healthcare Research and Quality (AHRQ) clinical practice guideline for treating tobacco use and dependence provides a number of recommendations for interventions by health care systems and providers, including that treatment be reimbursed, identification of tobacco users be institutionalized, and all patients be offered brief treatment and have more intensive treatment available to them. Unfortunately, these recommended interventions have not been routinely implemented. As part of a comprehensive approach to improving implementation, provider training is needed. Three models for training healthcare providers in brief tobacco treatment intervention (medical education, professional education, and community-based education) are described, a model for training providers in intensive tobacco treatment interventions is presented, and a rationale for a national training and certification program is made.

Treatments for spit tobacco use: a quantitative systematic review

AIMS

Spit tobacco use is prevalent in the United States and is associated with adverse health consequences. Health-care providers have neither evidence summaries nor evidence-based guidelines to assist them in treating patients who use spit tobacco.

DESIGN

We completed a systematic review of the literature to determine the efficacy and safety of pharmacological and behavioral interventions for the treatment of spit tobacco use.

FINDINGS

We found six randomized controlled trials testing pharmacological interventions and eight testing behavioral interventions. Using random-effects meta-analyses,bupropion sustained-release (SR) increased point prevalence tobacco abstinence at 12 weeks [odds ratio (OR) 2.1; 95% confidence interval (CI), 1.0-4.2]. Nicotine replacement therapy with patch or gum increased point prevalence tobacco abstinence at 6 months (OR 1.3; 95% CI, 1.0-1.6). Behavioral interventions increased long-term (6 month)point prevalence tobacco abstinence (OR 1.7; 95% CI, 1.1-2.9). Studies including an oral examination followed by feedback to the patient had the highest treatment effect.

CONCLUSIONS

Behavioral interventions for ST users are effective for increasing ST abstinence rates. Bupropion SR is probably effective and nicotine replacement therapy may be effective. This evidence from randomized controlled trials provides health-care professionals with information necessary to effectively treat spit tobacco use.

Paying for quality improvement: compliance with tobacco cessation guidelines

BACKGROUND

Identification and treatment of routine tobacco use in medical practice is an effective intervention but is not used consistently. A study was conducted at HealthPartners, a large network-model health plan in Minnesota, to determine the effect of an outcomes recognition strategy that involved bonus funds and the rates at which network physicians document that tobacco users are identified and advised to quit.

METHODS

Audits of 14,489 ambulatory patient records from 19-20 medical groups were conducted to determine the proportion of charts from each medical group that demonstrated identification of smoking status and counseling to encourage quitting at the most recent office visit in each year.

RESULTS

Overall mean tobacco use identification increased from 49% +/- 7% (95% confidence interval [CI]) in 1996 to 73% +/- 7% in 1999 (p < .001), while advice to quit increased from 32% +/- 10% in 1996 to 53% +/- 10% CI in 1999 (p < .005). The number of medical groups with tobacco status identified at > 80% of visits and > 80% of tobacco users advised to quit increased from 0 in 1996 to 8 in 1999.

DISCUSSION

Data feedback combined with a financial incentive appear to be an effective way for a health plan to improve physician compliance with the tobacco treatment guideline. Other health plans might consider similar reporting and incentive approaches to effectively engage medical group leadership and to improve the health of their members who use tobacco.

Brief physician-initiated quit-smoking strategies for clinical oncology settings: a trial coordinated by the Eastern Cooperative Oncology Group

PURPOSE

Although tobacco use by cancer patients increases the risk of relapse, diminishes treatment efficacy, and worsens quality of life, about one third of patients who smoked before their diagnosis continue to smoke. Because patients have regular contact with oncologists, the efficacy of a physician-based smoking cessation treatment was evaluated.

METHODS

Cancer patients (n = 432) were randomly assigned to either usual care or a National Institutes of Health (NIH) physician-based smoking intervention. The primary outcome was 7-day point prevalence abstinence at 6 and 12 months after study entry.

RESULTS

At the 6-month follow-up, there was no significant difference in quit rates between the usual care (11.9%) and intervention (14.4%) groups, and there was no significant difference between the usual care (13.6%) and intervention (13.3%) groups at the 12-month follow-up. Patients were more likely to have quit smoking at 6 months if they had head and neck or lung cancer, began smoking after the age of 16, reported at baseline using a cessation self-help guide or treatment in the last 6 months, and showed greater baseline desire to quit. Patients were more likely to have quit smoking at 12 months if they smoked 15 or fewer cigarettes per day, had head and neck or lung cancer, tried a group cessation program, and showed greater baseline desire to quit. Finally, there was greater adherence among physicians to the NIH model for physician smoking treatment for patients in the intervention versus the usual care group.

CONCLUSION

While training physicians to provide smoking cessation treatment to cancer patients can enhance physician adherence to clinical practice guidelines, physician smoking cessation interventions fail to yield significant gains in long-term quit rates among cancer patients.

Is there a role for assessment in smoking cessation treatment?

Recent strides have been made in smoking cessation as a number of behavioral and pharmacological treatments have proven effective. These treatments are briefly reviewed. The role of assessment in the treatment process, however, is less clear. Indeed, to date, there are few data suggesting that specialized assessment can be used to guide prescriptive treatment. As such, the question becomes one of how, or whether, assessment should be used in smoking cessation. We address these questions and argue that despite the dearth of empirical substantiation, certain aspects of smoking behavior should be assessed in that they: (1) help identify behavioral, physiological, and psychological conditions that maintain smoking, (2) help describe the problem (smoking) with enough clarity to foster both clinical understanding and diagnosis, and (3) offer prediction and evaluation of treatment process and outcome. Promising assessment-based treatments are also discussed, as well as recommendations for future directions pertaining to the role of assessment in smoking cessation.
