Feasibility of smoking cessation counseling by phone with alcohol treatment center graduates

Telephone counselling for smoking cessation

BACKGROUND

Telephone services can provide information and support for smokers. Counselling may be provided proactively or offered reactively to callers to smoking cessation helplines.

OBJECTIVES

To evaluate the effect of telephone support to help smokers quit, including proactive or reactive counselling, or the provision of other information to smokers calling a helpline.

SEARCH METHODS

We searched the Cochrane Tobacco Addiction Group Specialised Register, clinicaltrials.gov, and the ICTRP for studies of telephone counselling, using search terms including 'hotlines' or 'quitline' or 'helpline'. Date of the most recent search: May 2018.

SELECTION CRITERIA

Randomised or quasi-randomised controlled trials which offered proactive or reactive telephone counselling to smokers to assist smoking cessation.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. We pooled studies using a random-effects model and assessed statistical heterogeneity amongst subgroups of clinically comparable studies using the I² statistic. In trials including smokers who did not call a quitline, we used meta-regression to investigate moderation of the effect of telephone counselling by the planned number of calls in the intervention, trial selection of participants that were motivated to quit, and the baseline support provided together with telephone counselling (either self-help only, brief face-to-face intervention, pharmacotherapy, or financial incentives).

MAIN RESULTS

We identified 104 trials including 111,653 participants that met the inclusion criteria. Participants were mostly adult smokers from the general population, but some studies included teenagers, pregnant women, and people with long-term or mental health conditions. Most trials (58.7%) were at high risk of bias, while 30.8% were at unclear risk, and only 11.5% were at low risk of bias for all domains assessed. Most studies (100/104) assessed proactive telephone counselling, as opposed to reactive forms.Among trials including smokers who contacted helplines (32,484 participants), quit rates were higher for smokers receiving multiple sessions of proactive counselling (risk ratio (RR) 1.38, 95% confidence interval (CI) 1.19 to 1.61; 14 trials, 32,484 participants; I² = 72%) compared with a control condition providing self-help materials or brief counselling in a single call. Due to the substantial unexplained heterogeneity between studies, we downgraded the certainty of the evidence to moderate.In studies that recruited smokers who did not call a helpline, the provision of telephone counselling increased quit rates (RR 1.25, 95% CI 1.15 to 1.35; 65 trials, 41,233 participants; I² = 52%). Due to the substantial unexplained heterogeneity between studies, we downgraded the certainty of the evidence to moderate. In subgroup analysis, we found no evidence that the effect of telephone counselling depended upon whether or not other interventions were provided (P = 0.21), no evidence that more intensive support was more effective than less intensive (P = 0.43), or that the effect of telephone support depended upon whether or not people were actively trying to quit smoking (P = 0.32). However, in meta-regression, telephone counselling was associated with greater effectiveness when provided as an adjunct to self-help written support (P < 0.01), or to a brief intervention from a health professional (P = 0.02); telephone counselling was less effective when provided as an adjunct to more intensive counselling. Further, telephone support was more effective for people who were motivated to try to quit smoking (P = 0.02). The findings from three additional trials of smokers who had not proactively called a helpline but were offered telephone counselling, found quit rates were higher in those offered three to five telephone calls compared to those offered just one call (RR 1.27, 95% CI 1.12 to 1.44; 2602 participants; I² = 0%).

AUTHORS' CONCLUSIONS

There is moderate-certainty evidence that proactive telephone counselling aids smokers who seek help from quitlines, and moderate-certainty evidence that proactive telephone counselling increases quit rates in smokers in other settings. There is currently insufficient evidence to assess potential variations in effect from differences in the number of contacts, type or timing of telephone counselling, or when telephone counselling is provided as an adjunct to other smoking cessation therapies. Evidence was inconclusive on the effect of reactive telephone counselling, due to a limited number studies, which reflects the difficulty of studying this intervention.

Individual behavioural counselling for smoking cessation

BACKGROUND

Individual counselling from a smoking cessation specialist may help smokers to make a successful attempt to stop smoking.

OBJECTIVES

The review addresses the following hypotheses:1. Individual counselling is more effective than no treatment or brief advice in promoting smoking cessation.2. Individual counselling is more effective than self-help materials in promoting smoking cessation.3. A more intensive counselling intervention is more effective than a less intensive intervention.

SEARCH METHODS

We searched the Cochrane Tobacco Addiction Group Specialized Register for studies with counsel* in any field in May 2016.

SELECTION CRITERIA

Randomized or quasi-randomized trials with at least one treatment arm consisting of face-to-face individual counselling from a healthcare worker not involved in routine clinical care. The outcome was smoking cessation at follow-up at least six months after the start of counselling.

DATA COLLECTION AND ANALYSIS

Both authors extracted data in duplicate. We recorded characteristics of the intervention and the target population, method of randomization and completeness of follow-up. We used the most rigorous definition of abstinence in each trial, and biochemically-validated rates where available. In analysis, we assumed that participants lost to follow-up continued to smoke. We expressed effects as a risk ratio (RR) for cessation. Where possible, we performed meta-analysis using a fixed-effect (Mantel-Haenszel) model. We assessed the quality of evidence within each study using the Cochrane 'Risk of bias' tool and the GRADE approach.

MAIN RESULTS

We identified 49 trials with around 19,000 participants. Thirty-three trials compared individual counselling to a minimal behavioural intervention. There was high-quality evidence that individual counselling was more effective than a minimal contact control (brief advice, usual care, or provision of self-help materials) when pharmacotherapy was not offered to any participants (RR 1.57, 95% confidence interval (CI) 1.40 to 1.77; 27 studies, 11,100 participants; I² = 50%). There was moderate-quality evidence (downgraded due to imprecision) of a benefit of counselling when all participants received pharmacotherapy (nicotine replacement therapy) (RR 1.24, 95% CI 1.01 to 1.51; 6 studies, 2662 participants; I² = 0%). There was moderate-quality evidence (downgraded due to imprecision) for a small benefit of more intensive counselling compared to brief counselling (RR 1.29, 95% CI 1.09 to 1.53; 11 studies, 2920 participants; I² = 48%). None of the five other trials that compared different counselling models of similar intensity detected significant differences.

AUTHORS' CONCLUSIONS

There is high-quality evidence that individually-delivered smoking cessation counselling can assist smokers to quit. There is moderate-quality evidence of a smaller relative benefit when counselling is used in addition to pharmacotherapy, and of more intensive counselling compared to a brief counselling intervention.

Applying the Transtheoretical Model to Tobacco Cessation and Prevention: A Review of Literature

Objective.

To comprehensively review all published, peer-reviewed research on the Transtheoretical Model (TTM) and tobacco cessation and prevention by exploring the validity of its constructs, the evidence for use of interventions based on the TTM, the description of populations using TTM constructs, and the identification of areas for further research. The three research questions answered were: “How is the validity of the TTM as applied to tobacco supported by research?” “How does the TTM describe special populations regarding tobacco use?” “What is the nature of evidence supporting the use of stage-matched tobacco interventions?”

Data Source.

Computer Database search (PsychInfo, Medline, Current Contents, ERIC, CINAHL-Allied Health, and Pro-Quest Nursing) and manual journal search.

Inclusion/Exclusion Criteria.

All English, original, research articles on the TTM as it relates to tobacco use published in peer-reviewed journals prior to March 1, 2001, were included. Commentaries, editorials, and books were not included.

Data Extraction and Synthesis.

Articles were categorized as TTM construct validation, population descriptions using TTM constructs, or intervention evaluation using TTM constructs. Summary tables including study design, research rating, purpose, methods, findings, and implications were created. Articles were further divided into groups according to their purpose. Considering both the findings and research quality of each, the three research questions were addressed.

Results.

The 148 articles reviewed included 54 validation studies, 73 population studies, and 37 interventions (some articles fit two categories). Overall, the evidence in support of the TTM as applied to tobacco use was strong, with supportive studies being more numerous and of a better design than nonsupportive studies. Using established criteria, we rated the construct validity of the entire body of literature as good; however, notable concerns exist about the staging construct. A majority of stage-matched intervention studies provided positive results and were of a better quality than those not supportive of stage-matched interventions; thus, we rated the body of literature using stage-matched tobacco interventions as acceptable and the body of literature using non–stage-matched interventions as suggestive. Population studies indicated that TTM constructs are applicable to a wide variety of general and special populations both in and outside of the United States, although a few exceptions exist.

Conclusions.

Evidence for the validity of the TTM as it applies to tobacco use is strong and growing; however, it is not conclusive. Eight different staging mechanisms were identified, raising the question of which are most valid and reliable. Interventions tailored to a smoker's stage were successful more often than nontailored interventions in promoting forward stage movement. Stage distribution is well-documented for U.S. populations; however, more research is needed for non-U.S. populations, for special populations, and on other TTM constructs.

METelemedicine: a pilot study with rural alcohol users on community supervision

PURPOSE

This pilot study examined a telemedicine-based intervention using motivational enhancement therapy (METelemedicine) to reduce alcohol use among a sample of at-risk, rural alcohol users.

METHODS

A total of 127 rural alcohol users were recruited from community supervision offices and engaged in brief intervention sessions using telemedicine. Analysis examined alcohol outcomes at 3 months postbaseline.

FINDINGS

Findings indicated that although there were no overall differences between comparison groups on alcohol outcomes, 3+ sessions of METelemedicine significantly reduced the likelihood of any alcohol use by 72% (P < .05). In addition, 3+ sessions of the intervention predicted fewer days of drinking in the follow-up period, fewer drinks per week, and fewer days experiencing alcohol problems.

CONCLUSIONS

Findings demonstrate that telemedicine may be a promising approach to deliver interventions with alcohol users who may not utilize formal treatment services. This method has potential to decrease some of the barriers to access and use of evidence-based treatment for populations in need of services.

Telephone counselling for smoking cessation

BACKGROUND

Telephone services can provide information and support for smokers. Counselling may be provided proactively or offered reactively to callers to smoking cessation helplines.

OBJECTIVES

To evaluate the effect of proactive and reactive telephone support via helplines and in other settings to help smokers quit.

SEARCH METHODS

We searched the Cochrane Tobacco Addiction Group Specialised Register for studies of telephone counselling, using search terms including 'hotlines' or 'quitline' or 'helpline'. Date of the most recent search: May 2013.

SELECTION CRITERIA

randomized or quasi-randomised controlled trials in which proactive or reactive telephone counselling to assist smoking cessation was offered to smokers or recent quitters.

DATA COLLECTION AND ANALYSIS

One author identified and data extracted trials, and a second author checked them. The main outcome measure was the risk ratio for abstinence from smoking after at least six months follow-up. We selected the strictest measure of abstinence, using biochemically validated rates where available. We considered participants lost to follow-up to be continuing smokers. Where trials had more than one arm with a less intensive intervention we used only the most similar intervention without the telephone component as the control group in the primary analysis. We assessed statistical heterogeneity amongst subgroups of clinically comparable studies using the I² statistic. We considered trials recruiting callers to quitlines separately from studies recruiting in other settings. Where appropriate, we pooled studies using a fixed-effect model. We used a meta-regression to investigate the effect of differences in planned number of calls, selection for motivation, and the nature of the control condition (self help only, minimal intervention, pharmacotherapy) in the group of studies recruiting in non-quitline settings.

MAIN RESULTS

Seventy-seven trials met the inclusion criteria. Some trials were judged to be at risk of bias in some domains but overall we did not judge the results to be at high risk of bias. Among smokers who contacted helplines, quit rates were higher for groups randomized to receive multiple sessions of proactive counselling (nine studies, > 24,000 participants, risk ratio (RR) for cessation at longest follow-up 1.37, 95% confidence interval (CI) 1.26 to 1.50). There was mixed evidence about whether increasing the number of calls altered quit rates but most trials used more than two calls. Three studies comparing different counselling approaches during a single quitline contact did not detect significant differences. Of three studies that tested the provision of access to a hotline two detected a significant benefit and one did not.Telephone counselling not initiated by calls to helplines also increased quitting (51 studies, > 30,000 participants, RR 1.27; 95% CI 1.20 to 1.36). In a meta-regression controlling for other factors the effect was estimated to be slightly larger if more calls were offered, and in trials that specifically recruited smokers motivated to try to quit. The relative extra benefit of counselling was smaller when it was provided in addition to pharmacotherapy (usually nicotine replacement therapy) than when the control group only received self-help material or a brief intervention.A further eight studies were too diverse to contribute to meta-analyses and are discussed separately. Two compared different intensities of counselling, both of which detected a dose response; one of these detected a benefit of multiple counselling sessions over a single call for people prescribed bupropion. The others tested a variety of interventions largely involving offering telephone counselling as part of a referral or systems change and none detected evidence of effect.

AUTHORS' CONCLUSIONS

Proactive telephone counselling aids smokers who seek help from quitlines. Telephone quitlines provide an important route of access to support for smokers, and call-back counselling enhances their usefulness. There is limited evidence about the optimal number of calls. Proactive telephone counselling also helps people who receive it in other settings. There is some evidence of a dose response; one or two brief calls are less likely to provide a measurable benefit. Three or more calls increase the chances of quitting compared to a minimal intervention such as providing standard self-help materials, or brief advice, or compared to pharmacotherapy alone.

One-year outcomes of a drug abuse prevention program for older teens and emerging adults: evaluating a motivational interviewing booster component

OBJECTIVE

The present study tested the efficacy of motivational interviewing-based booster sessions for Project Toward No Drug Abuse (TND), a 12-session school-based curriculum targeting youth at risk for drug abuse. In addition, generalization of effects to risky sexual behavior was assessed. The 1-year outcomes evaluation of the project is presented.

METHOD

A total of 24 schools were randomized to one of three conditions: standard care control (SCC), TND classroom program only (TND-only), and TND plus motivational interviewing booster (TND + MI). A total of 1186 participants completed baseline and 1-year follow-up surveys. Following the classroom program, youth in the TND + MI condition received up to 3 sessions of MI in person or by telephone. Effects were examined on 30-day cigarette, alcohol, marijuana, and hard drug use, as well as measures of risky sexual behavior (number of sex partners, condom use, having sex while using drugs or alcohol).

RESULTS

Collapsed across the 2 program conditions, results showed significant reductions in alcohol use, hard drug use, and cigarette smoking relative to controls. These effects held for an overall substance use index. The MI booster component failed to achieve significant incremental effects above and beyond the TND classroom program. No effects were found on risky sexual behavior.

CONCLUSIONS

While the program effects of previous studies were replicated, the study failed to demonstrate that an adequately implemented MI booster was of incremental value at 1-year follow-up.

Design and methods for a randomized clinical trial comparing three outreach efforts to improve screening mammography adherence

Background

Despite the demonstrated need to increase screening mammography utilization and strong evidence that mail and telephone outreach to women can increase screening, most managed care organizations have not adopted comprehensive outreach programs. The uncertainty about optimum strategies and cost effectiveness have retarded widespread acceptance. While 70% of women report getting a mammogram within the prior 2 years, repeat mammography rates are less than 50%. This 5-year study is conducted though a Central Massachusetts healthcare plan and affiliated clinic. All womenhave adequate health insurance to cover the test.

Methods/Design

This randomized study compares 3 arms: reminder letter alone; reminder letter plus reminder call; reminder letter plus a second reminder and booklet plus a counselor call. All calls provide women with the opportunity to schedule a mammogram in a reasonable time. The invention period will span 4 years and include repeat attempts. The counselor arm is designed to educate, motivate and counsel women in an effort to alleviate PCP burden.

All women who have been in the healthcare plan for 24 months and who have a current primary care provider (PCP) and who are aged 51-84 are randomized to 1 of 3 arms. Interventions are limited to women who become ≥18 months from a prior mammogram. Women and their physicians may opt out of the intervention study.

Measurement of completed mammograms will use plan billing records and clinic electronic records. The primary outcome is the proportion of women continuously enrolled for ≥24 months who have had ≥1 mammogram in the last 24 months. Secondary outcomes include the number of women who need repeat interventions. The cost effectiveness analysis will measure all costs from the provider perspective.

Discussion

So far, 18,509 women aged 51-84 have been enrolled into our tracking database and were randomized into one of three arms. At baseline, 5,223 women were eligible for an intervention. We anticipate that the outcome will provide firm data about the maximal effectiveness as well as the cost effectiveness of the interventions both for increasing the mammography rate and the repeat mammography rate.

Stopping smoking during first year of substance use treatment predicted 9-year alcohol and drug treatment outcomes

This study examined the association between stopping smoking at 1 year after substance use treatment intake and long-term substance use outcomes. Nine years of prospective data from 1185 adults (39% female) in substance use treatment at a private health care setting were analyzed by multivariate logistic generalized estimating equation models. At 1 year, 14.1% of 716 participants who smoked cigarettes at intake reported stopping smoking, and 10.7% of the 469 non-smokers at intake reported smoking. After adjusting for sociodemographics, substance use severity and diagnosis at intake, length of stay in treatment, and substance use status at 1 year, those who stopped smoking at 1 year were more likely to be past-year abstinent from drugs, or in past-year remission of drugs and alcohol combined, at follow-ups than those who continued to smoke (OR=2.4, 95% CI: 1.2-4.7 and OR=1.6, 95% CI: 1.1-2.4, respectively). Stopping smoking at 1 year also predicted past-year alcohol abstinence through 9 years after intake among those with drug-only dependence (OR=2.4, 95% CI: 1.2-4.5). We found no association between past-year alcohol abstinence and change in smoking status at 1 year for those with alcohol dependence or other substance use diagnoses when controlling for alcohol use status at 1 year. Stopping smoking during the first year after substance use treatment intake predicted better long-term substance use outcomes through 9 years after intake. Findings support promoting smoking cessation among smoking clients in substance use treatment.

Helping men make an informed decision about prostate cancer screening: a pilot study of telephone counseling

OBJECTIVE

Evaluate a computer-assisted telephone counseling (CATC) decision aid for men considering a prostate specific antigen (PSA) test.

METHODS

Eligible men were invited by their primary care providers (PCPs) to participate. Those consenting received an educational booklet followed by CATC. The counselor assessed stage of readiness, reviewed booklet information, corrected knowledge deficits and helped with a values clarification exercise. The materials presented advantages and disadvantages of being screened and did not advocate for testing or for not testing. Outcome measures included changes in stage, decisional conflict, decisional satisfaction, perceived vulnerability and congruence of a PSA testing decision with a pros/cons score. Baseline and final surveys were administered by telephone.

RESULTS

There was an increase in PSA knowledge (p<0.001), and in decisional satisfaction (p<0.001), a decrease in decisional conflict (p<0.001), and a general consistency of those decisions with the man's values. Among those initially who had not made a decision, 83.1% made a decision by final survey with decisions equally for or against screening.

CONCLUSIONS

The intervention provides realistic, unbiased and effective decision support for men facing a difficult and confusing decision.

PRACTICE IMPLICATIONS

Our intervention could potentially replace a discussion of PSA testing with the PCP for most men.

The adoption of tobacco dependence treatment by rehabilitation clinicians

PURPOSE

Individuals with disabilities tend to smoke at rates that surpass those of the general population. The Pubic Health Service Guideline on the treatment of tobacco dependence suggests that all smokers be screened at every health care visit and counselled regarding how best to quit smoking. We review the literature on the adoption of tobacco dependence treatment by rehabilitation clinicians working with disabled individuals. Despite the deleterious health effects of smoking on individuals with disabilities, the limited data suggests that rehabilitation clinicians rarely encourage their clients who smoke to quit.

METHOD

Studies were collected using various computerized databases from 1980 to the present. Because of the paucity of literature on tobacco dependence treatment utilization among rehabilitation clinicians, we also examine research on the use of tobacco dependence treatment by health care providers in the general population and in substance abuse treatment settings.

RESULTS

Despite the efficacy of tobacco dependence treatment in smokers with disabilities, tobacco dependence treatment appears to be underutilized by rehabilitation clinicians.

CONCLUSIONS

Interventions that have successfully increased adoption by the two other clinician groups should be utilized to increase tobacco dependence treatment provision by rehabilitation clinicians. Additional research is warranted to determine how to overcome obstacles to adoption.

Project Towards No Drug Abuse (TND): needs assessment of a social service referral telephone program for high risk youth

The purpose of this study was to conduct a needs assessment of a potential social service resource telephone program component among high risk youth who received the Project Towards No Drug Abuse (TND) classroom-based program (approximately 1 year earlier). Results supported youths' overwhelming receptiveness of a social service referral program. The vast majority of respondents indicated a strong desire for resource and referral information on vocational, educational, recreational, transportation, and mental health and drug counseling. Further research is needed to investigate the effectiveness of the provision of social service resource information on drug use among emerging adults.

Using tailored telephone counseling to accelerate the adoption of colorectal cancer screening

BACKGROUND

Few interventions to increase colorectal cancer screening have used a stage of change model to promote screening adoption. None have used computer-assisted tailored telephone counseling calls. This study's purpose was to implement and evaluate stage-based computer-assisted tailored telephone counseling to promote colorectal cancer screening in a primary care population.

METHODS

This randomized controlled trial used a two-stepped intervention that included a mailed booklet on colorectal cancer screening followed by computer-assisted telephone counseling that was based on the Precaution Adoption Process Model. Chart audit was used to document completion of colonoscopy, sigmoidoscopy or fecal occult blood testing.

RESULTS

Record audits were completed on 2,474 (88%) of the 2,817 eligible participants. There was no significant difference in the frequency and nature of the screening tests completed in the study arms. In a sub-analysis, stages of adoption were evaluated pre- and post-telephone counseling. Over half those receiving counseling reported a change in stage towards screening adoption.

CONCLUSION

Overall, the intervention did not increase colorectal screening compared to control. Two possible reasons for the absence of a screening effect include: (a) the focus of the protocol on education for most patients rather than motivation, and (b) the requirement that patients interested in screening seek further information and a referral on their own from their providers. While those receiving telephone counseling improved their stage of adoption, we cannot rule out selection bias. Stronger physician recommendation to speak with the counselors could improve call acceptance. Future colorectal screening should address these weaknesses.

Telephone counselling for smoking cessation

BACKGROUND

Telephone services can provide information and support for smokers. Counselling may be provided proactively or offered reactively to callers to smoking cessation helplines.

OBJECTIVES

To evaluate the effect of proactive and reactive telephone support to help smokers quit.

SEARCH STRATEGY

We searched the Cochrane Tobacco Addiction Group trials register for studies using free text term 'telephone*' or the keywords 'telephone counselling' or 'Hotlines' or 'Telephone' . Date of the most recent search: January 2006.

SELECTION CRITERIA

Randomized or quasi-randomized controlled trials in which proactive or reactive telephone counselling to assist smoking cessation was offered to smokers or recent quitters.

DATA COLLECTION AND ANALYSIS

Trials were identified and data extracted by one person (LS) and checked by a second (TL). The main outcome measure was the odds ratio for abstinence from smoking after at least six months follow up. We selected the strictest measure of abstinence, using biochemically validated rates where available. We considered participants lost to follow-up to be continuing smokers. Where trials had more than one arm with a less intensive intervention we used only the most similar intervention without the telephone component as the control group in the primary analysis. We assessed statistical heterogeneity amongst sub groups of clinically comparable studies using the I(2) statistic. Where appropriate, we pooled studies using a fixed-effect model. A meta-regression was used to investigate the effect of differences in planned number of calls.

MAIN RESULTS

Forty-eight trials met the inclusion criteria. Among smokers who contacted helplines, quit rates were higher for groups randomised to receive multiple sessions of call-back counselling (eight studies, >18,000 participants, odds ratio (OR) for long term cessation 1.41, 95% confidence interval (CI) 1.27 to 1.57). Two of these studies showed a significant benefit of more intensive compared to less intensive intervention. Telephone counselling not initiated by calls to helplines also increased quitting (29 studies, >17,000 participants, OR 1.33, 95% CI 1.21 to 1.47). A meta-regression detected a significant association between the maximum number of planned calls and the effect size. There was clearer evidence of benefit in the subgroup of trials recruiting smokers motivated to quit. Of two studies that provided access to a hotline one showed a significant benefit and one did not. Two studies comparing different counselling approaches during a single session did not detect significant differences. A further seven studies were too diverse to contribute to meta-analyses and are discussed separately.

AUTHORS' CONCLUSIONS

Proactive telephone counselling helps smokers interested in quitting. There is evidence of a dose response; one or two brief calls are less likely to provide a measurable benefit. Three or more calls increases the odds of quitting compared to a minimal intervention such as providing standard self-help materials, brief advice, or compared to pharmacotherapy alone. Telephone quitlines provide an important route of access to support for smokers, and call-back counselling enhances their usefulness.

Implementing a computer-assisted telephone interview (CATI) system to increase colorectal cancer screening: a process evaluation

OBJECTIVE

Computer-assisted telephone interviewing (CATI) systems used by telephone counselors (TCs) may be efficient mechanisms to counsel patients on cancer and recommended preventive screening tests in order to extend a primary care provider's reach to his/her patients. The implementation process of such a system for promoting colorectal (CRC) cancer screening using a computer-assisted telephone interview (CATI) system is reported in this paper.

METHODS

The process evaluation assessed three components of the intervention: message production, program implementation and audience reception.

RESULTS

Of 1181 potentially eligible patients, 1025 (87%) patients were reached by the TCs and 725 of those patients (71%) were eligible to receive counseling. Five hundred eighty-two (80%) patients agreed to counseling.

CONCLUSIONS

It is feasible to design and use CATI systems for prevention counseling of patients in primary care practices.

PRACTICE IMPLICATIONS

CATI systems have the potential of being used as a referral service by primary care providers and health care organizations for patient education.

Individual behavioural counselling for smoking cessation

BACKGROUND

Individual counselling from a smoking cessation specialist may help smokers to make a successful attempt to stop smoking.

OBJECTIVES

The objective of the review is to determine the effects of individual counselling.

SEARCH STRATEGY

We searched the Cochrane Tobacco Addiction Group Specialized Register for studies with counsel* in any field. Date of the most recent search: December 2004.

SELECTION CRITERIA

Randomized or quasi-randomized trials with at least one treatment arm consisting of face-to-face individual counselling from a healthcare worker not involved in routine clinical care. The outcome was smoking cessation at follow up at least six months after the start of counselling.

DATA COLLECTION AND ANALYSIS

Both authors extracted data. The intervention and population, method of randomization and completeness of follow up were recorded.

MAIN RESULTS

We identified 21 trials with over 7000 participants. Eighteen trials compared individual counselling to a minimal behavioural intervention, four compared different types or intensities of counselling. Individual counselling was more effective than control. The odds ratio for successful smoking cessation was 1.56 (95% confidence interval 1.32 to 1.84). In a subgroup of three trials where all participants received nicotine replacement therapy the point estimate of effect was smaller and did not reach significance (odds ratio 1.34, 95% confidence interval 0.98 to 1.83). We failed to detect a greater effect of intensive counselling compared to brief counselling (odds ratio 0.98, 95% confidence interval 0.61 to 1.56).

AUTHORS' CONCLUSIONS

Smoking cessation counselling can assist smokers to quit.

Quitlines in North America: evidence base and applications

Quitlines provide a model for the translation of research findings to public health application. Quitlines are currently in operation in more than half of US states, in Canada, and in multiple countries globally. Overall, when implemented correctly, quitlines have been shown to be efficacious and effective. Multiple quitline models are in use, but there is no evidence on the relative effectiveness of one over the other. Differences have been demonstrated for the efficacy of quitlines for specific applications, with the strongest evidence base for application as a primary intervention or as follow-up for hospitalized patients and particularly for cardiac patients. The evidence base for both reactive and proactive services is reviewed, and future directions to continue to advance the field are discussed.

Telephone counselling for smoking cessation

BACKGROUND

Telephone services can provide information and support for smokers. Counselling may be provided proactively or offered reactively to callers to smoking cessation helplines.

OBJECTIVES

To evaluate the effect of proactive and reactive telephone support to help smokers quit.

SEARCH STRATEGY

We searched the Cochrane Tobacco Addiction Group trials register for studies using free text term 'telephone*' or the keywords 'telephone counselling' or 'Hotlines' or 'Telephone'. Date of the most recent search: September 2002.

SELECTION CRITERIA

Randomised or quasi-randomised controlled trials in which proactive or reactive telephone counselling to assist smoking cessation was offered to smokers or recent quitters.

DATA COLLECTION AND ANALYSIS

Trials were identified and data extracted by one person and checked by a second. The main outcome measure was abstinence from smoking after at least six months follow-up. We used the most rigorous definition of abstinence in each trial, and biochemically validated rates where available. Participants lost to follow-up were considered to be continuing smokers. Where trials had more than one arm with a less intensive intervention we used only the most similar intervention as the control group in the primary analysis. Where interventions were similar, we performed meta-analysis using a fixed effects model (Peto method) to give an odds ratio.

MAIN RESULTS

Twenty seven trials met inclusion criteria. Thirteen trials compared proactive counselling to a minimal intervention control. There was statistical heterogeneity, with five trials showing a significant benefit, and eight showing non significant differences. The heterogeneity was associated with trials that provided tailored self-help materials to the control group. Meta-analysis using all less intensive intervention arms as the control removed the heterogeneity and suggests that telephone counselling compared to less intensive intervention increases quit rates (OR 1.56, 1.38 - 1.77). Four trials adding telephone support to a face to face intervention control failed to detect a significant effect on long term quit rates. Four trials failed to detect an additional effect of telephone support in users of nicotine replacement therapy. Providing access to a hotline showed a significant benefit in one trial and no significant difference in two. No differences in outcome were detected in trials that compared different types of telephone counselling.

REVIEWER'S CONCLUSIONS

Proactive telephone counselling can be effective compared to an intervention without personal contact. Successful interventions generally involve multiple contacts timed around a quit attempt. The available evidence neither confirms nor rules out a benefit of telephone counselling as an adjunct to face to face counselling or pharmacotherapy. Further trials randomising access to helplines are unlikely to be done but indirect evidence suggests they can be a useful part of a smoking cessation service.

Smoking cessation among persons in recovery

The literature on smoking cessation for those in recovery from other drug use is reviewed. Reasons for engaging in this work, arguments against treatment of smoking along with another drug, characteristics of drug users who smoke, and treatment content implications are reviewed. Outcomes of 24 studies are presented. It is concluded that the future of research and practice in this arena should include facilitating smoking cessation among those early in recovery.

Examination of the transtheoretical model in current smokers

Although the transtheoretical model of behavior change has frequently been used as a basisfor smoking-cessation programs, in very few studies have the study variables been linked with the theoretical concepts. This study used a convenience sample of 79 current smokers to determine the relationships among the stages of change and the processes of change. Logistic regressions were used in order to determine whether certain processes were related to specific stages and whether specific processes were related to movement among the stages. Participants in the precontemplation stage and the preparation stage were found to rely on specific processes, whereas those in the contemplation stage did not.

We searched the Cochrane Tobacco Addiction Group trials register for studies with counsel* in any field. Date of the most recent search: February 2002.

SELECTION CRITERIA

Randomised or quasi-randomised trials with at least one treatment arm consisting of face to face individual counselling from a health care worker not involved in routine clinical care. The outcome was smoking cessation at follow-up at least six months after the start of counselling.

DATA COLLECTION AND ANALYSIS

Both reviewers extracted data. The intervention and population, method of randomisation and completeness of follow-up were recorded.

MAIN RESULTS

We identified eighteen trials. Fifteen compared individual counselling to a minimal intervention, four compared different types or intensities of counselling. Individual counselling was more effective than control. The odds ratio for successful smoking cessation was 1.62 (95% confidence interval 1.35 to 1.94). We failed to detect a greater effect of intensive counselling compared to brief counselling (odds ratio 0.98, 95% confidence interval 0.61 to 1.56).

REVIEWER'S CONCLUSIONS

Smoking cessation counselling can assist smokers to quit.

Attitudes toward smoking and smoking behaviors of patients with Crohn's disease

OBJECTIVE

To examine the smoking behaviors of people with Crohn's disease. In active smokers, we measured their willingness to quit, their degree of nicotine dependence, and the proportion that made a quit attempt within 6 months to determine if they were refractory to smoking cessation in comparison to the general population. We also examined factors that were important in their decision to smoke.

METHODS

We conducted a cross-sectional survey of out-patients, supplemented by telephone interviews and a 6-month follow-up questionnaire of active smokers. Measures included disease activity, current smoking behaviors, intentions (stage of change), Fagerstrom Test for Nicotine Dependence, and factors related to their decision to smoke (decisional balance).

RESULTS

The questionnaire was completed by 115 patients (78% response rate). Forty percent were active smokers. Of active smokers, 59% were considering quitting within the next 6 months, and of these, 15% were planning on quitting within the next 30 days. Those with moderate disease activity were more likely to be considering quitting than those with mild or severe activity. Nicotine dependence was rated as high in 33% and as moderate in 43%. Factors unrelated to Crohn's disease were more important in their decision to smoke than were Crohn's disease-related factors. After 6 months, 23% had made an attempt to quit and this attempt was strongly associated with their stated intentions at the baseline questionnaire. Two of three patients who had recently quit at baseline had resumed smoking.

CONCLUSION

When compared to similar data for the general population, patients with Crohn's disease are no more refractory to smoking cessation.

Tobacco cessation with patients recovering from alcohol and other substance abuse

This article focuses on the problem of tobacco cessation in the patient recovering from alcohol or other substance abuse. The authors review the epidemiology of the problem, specific health risks to this population from continued tobacco use, and recent research findings that address previous treatment concerns. Recommendations for counseling by physicians are made. These include an algorithm for determining the patient's stage of readiness for making a quit attempt, specific counseling tasks based on the patients stage, and motivational counseling strategies aimed at increasing the patients motivation to quit.
