Long-Term Engagement in Smoking Cessation Counseling among Rural Smokers

Engaging Patients in Smoking Cessation Treatment within the Lung Cancer Screening Setting: Lessons Learned from an NCI SCALE Trial

Offering smoking cessation treatment at lung cancer screening (LCS) will maximize mortality reduction associated with screening, but predictors of treatment engagement are not well understood. We examined participant characteristics of engagement in an NCI SCALE cessation trial. Eligible LCS patients (N = 818) were randomized to the Intensive arm (8 phone counseling sessions +8 weeks of nicotine replacement therapy (NRT)) vs. Minimal arm (3 sessions + 2 weeks of NRT). Engagement was measured by number of sessions completed (none, some, or all) and NRT mailed (none vs. any) in each arm. In the Intensive arm, those with ≥some college (OR = 2.1, 95% CI = 1.1, 4.0) and undergoing an annual scan (OR = 2.1, 95% CI = 1.1, 4.2) engaged in some counseling vs. none. Individuals with higher nicotine dependence were more likely (OR = 2.8, 95% CI = 1.3, 6.2) to request NRT. In the Minimal arm, those with higher education (OR = 2.1, 95% CI = 1.1, 3.9) and undergoing an annual scan (OR = 2.0, 95% CI = 1.04, 3.8) completed some sessions vs. none. Requesting NRT was associated with more pack-years (OR = 1.9, 95% CI = 1.1, 3.5). Regardless of treatment intensity, additional strategies are needed to engage those with lower education, less intensive smoking histories, and undergoing a first scan. These efforts will be important given the broader 2021 LCS guidelines.

A pre-evaluation of psychological factors may positively affect the outcomes of smoking cessation treatments: A comparison in terms of smoking behavior

INTRODUCTION

The aim of this study was to compare smoking behavior in out-patients in terms of psychological factors with a view to supporting cessation treatment.

METHODS

We conducted a cross-sectional and analytical study through face-to-face interviews by the primary care physician with 765 volunteer participants who applied to our hospital for any reason between March and July 2019. The questionnaire administered had two parts: questions about sociodemographic characteristics and usage of tobacco and tobacco products, and questions of the UCLA Loneliness Scale, Multidimensional Scale of Perceived Social Support (MSPSS), Warwick-Edinburgh Mental Wellbeing Scale (WEMBS), and Fagerström Test for Nicotine Dependence (FTND).

RESULTS

The study was completed with 765 participants of which 53.1% (n=406) were female and 46.9% (n=359) male. Multidimensional perceived social support scale mean score of the participants was 69.9±15.2 (min=12, max=84). There was a significant relation between mean MPSS and mean WEMBS (p<0.05). As nicotine scores increased, the mean scores both in MPSS and WEMBS decreased (p<0.05).

CONCLUSIONS

We suggest that the results of the psychometric preliminary evaluations should be customized for individuals applying to smoking cessation clinics and that including the individual's close social connections in the process can facilitate the decision to quit, thus increase smoking cessation rates.

Remission from nicotine dependence among people with severe mental illness who received help/services for tobacco/nicotine use

OBJECTIVES

A growing body of evidence supports pharmacological interventions to assist smoking cessation in people with severe mental illness (SMI); that is, lifetime major depressive disorder, bipolar disorders, or schizophrenia. Little is known about whether behavioral services are also associated with high probability of remission from nicotine dependence as compared to other types of help/services received (pharmacological, behavioral, or both).

METHODS

A sample of 726 American lifetime adult smokers with SMI and a history of nicotine dependence, who received help/services for tobacco/nicotine use, were identified. These data came from a limited public use dataset, the 2012-2013 NESARC-III. Survival analysis was used to compare the probability of remission from nicotine dependence and the time needed for full remission from nicotine dependence by type of help/services received for tobacco/nicotine use.

RESULTS

Remission was more frequent among those who received behavioral services. In addition, the average time from onset of nicotine dependence until full remission from nicotine dependence was shorter among those who received behavioral services.

CONCLUSIONS

The current study suggests a clinical need for behavioral interventions to promote the probability of remission from nicotine dependence among smokers with SMI. Health care providers could play a role in educating and encouraging smokers with SMI to seek and utilize behavioral services.

Additional behavioural support as an adjunct to pharmacotherapy for smoking cessation

BACKGROUND

Pharmacotherapies for smoking cessation increase the likelihood of achieving abstinence in a quit attempt. It is plausible that providing support, or, if support is offered, offering more intensive support or support including particular components may increase abstinence further.

OBJECTIVES

To evaluate the effect of adding or increasing the intensity of behavioural support for people using smoking cessation medications, and to assess whether there are different effects depending on the type of pharmacotherapy, or the amount of support in each condition. We also looked at studies which directly compare behavioural interventions matched for contact time, where pharmacotherapy is provided to both groups (e.g. tests of different components or approaches to behavioural support as an adjunct to pharmacotherapy).

SEARCH METHODS

We searched the Cochrane Tobacco Addiction Group Specialised Register, clinicaltrials.gov, and the ICTRP in June 2018 for records with any mention of pharmacotherapy, including any type of nicotine replacement therapy (NRT), bupropion, nortriptyline or varenicline, that evaluated the addition of personal support or compared two or more intensities of behavioural support.

SELECTION CRITERIA

Randomised or quasi-randomised controlled trials in which all participants received pharmacotherapy for smoking cessation and conditions differed by the amount or type of behavioural support. The intervention condition had to involve person-to-person contact (defined as face-to-face or telephone). The control condition could receive less intensive personal contact, a different type of personal contact, written information, or no behavioural support at all. We excluded trials recruiting only pregnant women and trials which did not set out to assess smoking cessation at six months or longer.

DATA COLLECTION AND ANALYSIS

For this update, screening and data extraction followed standard Cochrane methods. The main outcome measure was abstinence from smoking after at least six months of follow-up. We used the most rigorous definition of abstinence for each trial, and biochemically-validated rates, if available. We calculated the risk ratio (RR) and 95% confidence interval (CI) for each study. Where appropriate, we performed meta-analysis using a random-effects model.

MAIN RESULTS

Eighty-three studies, 36 of which were new to this update, met the inclusion criteria, representing 29,536 participants. Overall, we judged 16 studies to be at low risk of bias and 21 studies to be at high risk of bias. All other studies were judged to be at unclear risk of bias. Results were not sensitive to the exclusion of studies at high risk of bias. We pooled all studies comparing more versus less support in the main analysis. Findings demonstrated a benefit of behavioural support in addition to pharmacotherapy. When all studies of additional behavioural therapy were pooled, there was evidence of a statistically significant benefit from additional support (RR 1.15, 95% CI 1.08 to 1.22, I² = 8%, 65 studies, n = 23,331) for abstinence at longest follow-up, and this effect was not different when we compared subgroups by type of pharmacotherapy or intensity of contact. This effect was similar in the subgroup of eight studies in which the control group received no behavioural support (RR 1.20, 95% CI 1.02 to 1.43, I² = 20%, n = 4,018). Seventeen studies compared interventions matched for contact time but that differed in terms of the behavioural components or approaches employed. Of the 15 comparisons, all had small numbers of participants and events. Only one detected a statistically significant effect, favouring a health education approach (which the authors described as standard counselling containing information and advice) over motivational interviewing approach (RR 0.56, 95% CI 0.33 to 0.94, n = 378).

AUTHORS' CONCLUSIONS

There is high-certainty evidence that providing behavioural support in person or via telephone for people using pharmacotherapy to stop smoking increases quit rates. Increasing the amount of behavioural support is likely to increase the chance of success by about 10% to 20%, based on a pooled estimate from 65 trials. Subgroup analysis suggests that the incremental benefit from more support is similar over a range of levels of baseline support. More research is needed to assess the effectiveness of specific components that comprise behavioural support.

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.

Increasing access to smoking cessation treatment among Latino smokers using case management

Introduction

Disparities exist among Latino smokers with respect to knowledge and access to smoking cessation resources. This study tested the feasibility of using case management (CM) to increase access to pharmacotherapy and quitlines among Latino smokers.

Methods

Latino smokers were randomized to CM (n = 40) or standard care (SC, n = 40). All participants received educational materials describing how to utilize pharmacy assistance for cessation pharmacotherapy and connect with quitlines. CM participants received four phone calls from staff to encourage pharmacotherapy and quitline use. At 6-months follow-up, we assessed the utilization of pharmacotherapy and quitline. Additional outcomes included self-reported smoking status and approval for pharmacotherapy assistance.

Results

Using intention-to-treat analysis, CM produced higher utilization than SC of both pharmacotherapy (15.0% versus 2.5%; P = 0.108) and quitlines (12.5% versus 5.0%; P = 0.432), although differences were not statistically significant. Approval for pharmacotherapy assistance programs (20.0% versus 0.0%; P = 0.0005) was significantly higher for CM than SC participants. Self-reported point-prevalence smoking abstinence at 6-months were 20.0% and 17.5% for CM and SC, respectively (P = 0.775).

Conclusions

CM holds promise as an effective intervention to connect Latino smokers to evidence-based cessation treatment.

Predictors of smoking cessation group treatment engagement among veterans with serious mental illness

High prevalence rates of tobacco use, particularly cigarettes, pose a serious health threat for individuals with serious mental illness (SMI), and research has demonstrated the effectiveness of pharmacotherapy and psychosocial interventions to reduce tobacco use in this group. However, few studies have considered predictors of tobacco cessation treatment engagement among individuals with SMI. The current study examined predictors of engagement in smoking cessation groups among veterans with SMI engaged in mental health services at three VA medical centers. All veterans were participating in a smoking cessation treatment study. Of 178 veterans who completed baseline assessments, 127 (83.6%) engaged in treatment, defined as attending at least three group sessions. Forty-one (N=41) predictors across five domains (demographics, psychiatric concerns, medical concerns, smoking history, and self-efficacy to quit smoking) were identified based on previous research and clinical expertise. Using backward elimination to determine a final multivariable logistic regression model, three predictors were found to be significantly related to treatment engagement: marital status (never-married individuals more likely to engage); previous engagement in group smoking cessation services; and greater severity of positive symptoms on the Brief Psychiatric Rating Scale. When included in the multivariable logistic regression model, the full model discriminates between engagers and non-engagers reasonably well (c statistic=0.73). Major considerations based on these findings are: individuals with SMI appear to be interested in smoking cessation services; and serious psychiatric symptomatology should not discourage treatment providers from encouraging engagement in smoking cessation services.

The Influence of Engagement and Satisfaction on Smoking Cessation Interventions: A Qualitative Study

BACKGROUND

Tobacco use remains the leading cause of preventable disease and death. Most smokers are not motivated to quit; however, most smoking cessation interventions are designed for smokers who are ready to take action.

OBJECTIVES

The aim of the present study was to describe participant engagement and satisfaction with telephonic smoking cessation coaching with a population of smokers at different stages of readiness to quit.

METHODS

Qualitative description was used to capture the experiences of 62 individuals who participated in telephonic smoking cessation coaching using semistructured interviews.

RESULTS

Results indicate that person-centered communication facilitated engagement and was valued equally or more than perceived coach smoking cessation knowledge. Engagement with the intervention was associated with increased satisfaction, smoking cessation/reduction and perceived convenience of intervention. Conclusions/Importance: Findings indicate that unmotivated smokers can be proactively recruited and engaged in telephonic smoking cessation treatment and that person-centered communication and convenience are important variables that should be considered when implementing health interventions. Telephonic coaching has the potential to reach a large segment of the population with access barriers and could lead to important health behavior change. Intensive provider training that includes person-centered communication strategies is strongly recommended. Specific suggestions for successful implementation and dissemination are provided.

Advances in Motivational Interviewing for Pediatric Obesity: Results of the Brief Motivational Interviewing to Reduce Body Mass Index Trial and Future Directions

Rates of childhood obesity in the United States remain at historic highs. The pediatric primary care office represents an important yet underused setting to intervene with families. One factor contributing to underuse of the primary care setting is lack of effective available interventions. One evidence-based method to help engage and motivate patients is motivational interviewing, a client-centered and goal-oriented style of counseling used extensively to increase autonomous motivation and modify health behaviors. This article summarizes the methods and results from a large trial implemented in primary care pediatric office and concludes with recommendations for improving the intervention and increasing its dissemination.

A pilot study of home-based smoking cessation programs for rural, appalachian, pregnant smokers

OBJECTIVE

To evaluate a web-based contingency management program (CM) and a phone-delivered cessation counseling program (Smoking Cessation for Healthy Births [SCHB]) with pregnant smokers in rural Appalachia who were ≤12 weeks gestation at enrollment.

DESIGN

Two group randomized design.

SETTING

Home-based cessation programs in rural Appalachia Ohio and Kentucky.

PARTICIPANTS

A community sample of pregnant smokers (N = 17).

METHODS

Participants completed demographic and smoking-related questionnaires and were assigned to CM (n = 7) or SCHB (n = 10) conditions. Smoking status was assessed monthly using breath carbon monoxide and urinary cotinine.

RESULTS

For CM, two of seven (28.57%) of the participants achieved abstinence, and three of 10 (30%) of those enrolled in SCHB were abstinent by late in pregnancy. Participants in CM attained abstinence more rapidly than those in SCHB. However, those in SCHB experienced less relapse to smoking, and a greater percentage of these participants reduced their smoking by at least 50%.

CONCLUSION

Based on this initial evaluation, the web-based CM and SCHB programs appeared to be feasible for use with rural pregnant smokers with acceptable program adherence for both approaches. Future researchers could explore combining these programs to capitalize on the strengths of each, for example, rapid smoking cessation based on CM incentives and better sustained cessation or reductions in smoking facilitated by the counseling support of SCHB.

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.

A picture may be worth a thousand texts: obese adolescents' perspectives on a modified photovoice activity to aid weight loss

BACKGROUND

In an effort to enhance the vividness and personal relevance of a text messaging intervention to promote weight loss among obese adolescents, a modified Photovoice process was evaluated with adolescents in a weight management program.

METHODS

Photovoice is a method using photography to generate relevant images and stories from users. Participants were recruited from the Michigan Pediatric Outpatient Weight Evaluation and Reduction (MPOWER) program, a multidisciplinary weight management program for obese adolescents and their parents. Twenty-three adolescents with a mean BMI of 40 were asked to take pictures on three to five randomly assigned weight-related topics, such as “something that reminds you to exercise,” and to text them to a research assistant. Adolescents then engaged in semistructured interviews about the experience. Detailed notes of the interviews were analyzed to identify themes.

RESULTS

Participants generally provided high ratings of the process, indicating that (1) deciding what pictures to take caused them to reflect on their weight loss experience, and (2) a mobile intervention incorporating personally relevant images (e.g., basketball as their favorite sport rather than sports in general) would increase treatment adherence. The submitted photographs frequently featured family members and friends, and participants indicated that family and friends played a major role in motivating and supporting them.

CONCLUSIONS

This study suggests that a Photovoice component has the potential to enhance weight management programs for teens as part of a text messaging intervention and as an independent entity. Further work should evaluate the effect of this promising intervention on weight loss.

Tobacco use and exposure in rural areas: Findings from the Behavioral Risk Factor Surveillance System

Evidence suggests that those residing in rural areas may be disproportionately affected by the health burden of tobacco use. The present study examined tobacco use, self-reported exposure to tobacco smoke, and policies regarding public smoking according to area of residence using data from the 2006 and 2008 Behavioral Risk Factor Surveillance System. Results indicated that, relative to those from suburban and urban locations, adults residing in rural areas were significantly more likely to smoke cigarettes (22.2% versus 17.3% (suburban) and 18.1% (urban), p<.001) and to use smokeless tobacco (p<.001). Rural residents were also more likely than those living in suburban and urban areas to report that someone had smoked in their presence during the past seven days both at home (p<.001) and at work (p<.001). Finally, rural participants reported policies that afforded less protection from tobacco smoke both at home and in the workplace. These findings suggest that those living in rural areas are at increased risk for tobacco-related illness due to both their own tobacco use and exposure to others' cigarette smoke.

Embracing chaos and complexity: a quantum change for public health

Public health research and practice have been guided by a cognitive, rational paradigm where inputs produce linear, predictable changes in outputs. However, the conceptual and statistical assumptions underlying this paradigm may be flawed. In particular, this perspective does not adequately account for nonlinear and quantum influences on human behavior. We propose that health behavior change is better understood through the lens of chaos theory and complex adaptive systems. Key relevant principles include that behavior change (1) is often a quantum event; (2) can resemble a chaotic process that is sensitive to initial conditions, highly variable, and difficult to predict; and (3) occurs within a complex adaptive system with multiple components, where results are often greater than the sum of their parts.
