Training general practitioners in the ABC versus 5As method of delivering stop-smoking advice: a pragmatic, two-arm cluster randomised controlled trial

This study assessed the effectiveness of a 3.5-h training session for general practitioners (GPs) in providing brief stop-smoking advice and compared two methods of giving advice - ABC versus 5As - on the rates of delivery of such advice and of recommendations of evidence-based smoking cessation treatment during routine consultations. A pragmatic, two-arm cluster randomised controlled trial was carried out including a pre-/post-design for the analyses of the primary outcome in 52 GP practices in Germany. Practices were randomised (1:1) to receive a 3.5-h training session (ABC or 5As). In total, 1937 tobacco-smoking patients, who consulted trained GPs in these practices in the 6 weeks prior to or following the training, were included. The primary outcome was patient-reported rates of GP-delivered stop-smoking advice prior to and following the training, irrespective of the training method. Secondary outcomes were patient-reported receipt of recommendation/prescription of behavioural therapy, pharmacotherapy or combination therapy for smoking cessation, and the effectiveness of ABC versus 5As regarding all outcomes. GP-delivered stop-smoking advice increased from 13.1% (n=136 out of 1039) to 33.1% (n=297 out of 898) following the training (adjusted odds ratio (aOR) 3.25, 95% CI 2.34-4.51). Recommendation/prescription rates of evidence-based treatments were low (<2%) pre-training, but had all increased after training (e.g. behavioural support: aOR 7.15, 95% CI 4.02-12.74). Delivery of stop-smoking advice increased non-significantly (p=0.08) stronger in the ABC versus 5As group (aOR 1.71, 95% CI 0.94-3.12). A single training session in stop-smoking advice was associated with a three-fold increase in rates of advice giving and a seven-fold increase in offer of support. The ABC method may lead to higher rates of GP-delivered advice during routine consultations.

Quit attempts and tobacco abstinence in primary care patients: follow-up of a pragmatic, two-arm cluster randomised controlled trial on brief stop-smoking advice - ABC versus 5As

We developed a 3.5-h training for general practitioners (GPs) in delivering brief stop-smoking advice according to different methods (ABC, 5As). In a pragmatic, cluster randomised controlled trial our training proved effective in increasing GP-delivered rates of such advice (from 13% to 33%). In this follow-up analysis we examined the effect of the training and compared ABC versus 5As on patient-reported quit attempts and point prevalence abstinence at weeks 4, 12 and 26 following GP consultation. Follow-up data were collected in 1937 smoking patients - independently of the receipt of GP advice - recruited before or after the training of 69 GPs. At week 26, ∼70% of the patients were lost to follow-up. All 1937 patients were included in an intention-to-treat analysis; missing outcome data were imputed. Quit attempts and abstinence rates did not differ significantly from pre- to post-training or between patients from the ABC versus the 5As group. However, ancillary analyses showed that patients who received GP advice compared to those who did not had two times higher odds of reporting a quit attempt at all follow-ups and abstinence at week 26. We reported that our training increases GP-delivered rates of stop-smoking advice, and the present analysis confirms that advice is associated with increased quit attempts and abstinence rates in patients. However, our training did not further improve these rates, which might be related to patients' loss to follow-up or to contextual factors, e.g. access to free evidence-based cessation treatment, which can hamper the transfer of GPs' advice into patients' behaviour change.

Do people know that cigarette filters are mainly composed of synthetic material? A representative survey of the German population (the DEBRA study)

INTRODUCTION

Most cigarettes are smoked with filters made of synthetic plastic, which are not fully biodegradable. Littering used cigarette filters (butts) represents a substantial environmental hazard. It is unclear if people, in particular smokers, know that filters consist of synthetic plastic.

METHODS

We used data collected in August/September 2019 from a representative household survey of the German population aged 14 years and over (wave 20 of the German Study on Tobacco Use; DEBRA). Respondents were asked: 'The majority of smokers use cigarettes with a filter. What do you think these filters are composed of? (1) Mainly of natural material; (2) Mainly of synthetic material; (3) I don't know what cigarette filters are composed of.' Response option 2 indicated correct knowledge.

RESULTS

A total of 2066 people were interviewed, including 625 current smokers. The weighted response rate to option 2 ('mainly of synthetic material') was 34.8% (95%CI 32.7 to 36.9) in the total sample and 42.7% (95%CI=38.7 to 46.8) in the subgroup of current smokers. In the latter subgroup, smokers with low compared with those with high educational level were less likely to know that filters are mainly composed of synthetic material (OR=0.62, 95%CI=0.39 to 0.99).

CONCLUSIONS

The majority of smokers in Germany does not know that cigarette filters are mainly composed of synthetic material. Our findings suggest a need for promoting awareness as well as knowledge of environmental health hazards of cigarette filters to the general population, and specifically to current smokers.

Measuring fidelity to delivery of a new smoking cessation intervention integrated into routine tuberculosis care in Pakistan and Bangladesh: Contextual differences and opportunities

INTRODUCTION

Tobacco smoking among tuberculosis (TB) patients leads to poorer treatment outcomes. Smoking cessation support should be integrated into routine TB care. We measured healthcare providers' fidelity to a smoking cessation intervention integrated into routine TB care, in Bangladesh and Pakistan. We aimed to understand the role of providers and settings in the implementation of behavior support (BS) messages for TB and smoking cessation.

METHODS

The integrated BS intervention was implemented in TB clinics (24 public and 1 private). Cross-sectional data were collected on the fidelity of delivery of the BS intervention using a predefined fidelity index based on an existing validated method of measuring intervention fidelity. Audio-recordings of patient-provider BS sessions were coded using the fidelity index. Intervention fidelity was presented as the proportion of sessions that implemented BS messages.

RESULTS

A total of 96 sessions were conducted, 37 in Bangladesh and 59 in Pakistan. In public settings, TB medication advice was offered in 91.9% (95% CI: 78.7- 97.2) of sessions in Bangladesh, and in 75.5% (95% CI: 62.4-85.1) of sessions in Pakistan; whilst it was offered in 83.3% (95% CI: 43.7-97.0) of sessions in the private setting in Pakistan. Patients' smoking status was assessed in 70.3% (95% CI: 54.2-82.5) of sessions in Bangladesh, and in 34.0% (95% CI: 22.7-47.4) of sessions in the public setting and in 66.7% (95% CI: 30.0-90.3) of sessions in the private setting in Pakistan. A quit date was set in 32.4% (95% CI: 19.6-48.5) of all sessions in Bangladesh, and in 33.3% (95% CI: 9.6-70.0) of all sessions in the public setting in Pakistan.

CONCLUSIONS

Fidelity to the intended delivery of the intervention was found to be high for TB-related messages but not for smoking cessation messages. Clinic contexts may play a mediating role in health workers' opportunities to deliver the intervention as planned.

S3-Leitlinie „Rauchen und Tabakabhängigkeit: Screening, Diagnostik und Behandlung“

Zusammenfassung. Einleitung: Neben der Prävention des Tabakkonsums bleibt die Herstellung und Sicherung eines hohen Niveaus der Behandlungsqualität bei schädlichem Gebrauch und Abhängigkeit von Tabakprodukten eine wichtige gesundheitsbezogene Aufgabe in Deutschland. Eine regelmäßige Aktualisierung der AWMF-S3-Leitlinie „Rauchen und Tabakabhängigkeit: Screening, Diagnostik und Behandlung“ schafft eine nachhaltige und seriöse Quelle für den Wissensstand zur Tabakentwöhnung. Methoden: Unter Federführung der Deutschen Gesellschaft für Psychiatrie, Psychotherapie, Psychosomatik und Nervenheilkunde (DGPPN) und der Deutschen Gesellschaft für Suchtforschung und Suchttherapie e. V. (DG-Sucht) wurde die Tabakleitlinie 2019–2020 von insgesamt 63 am Entstehungsprozess des Textes beteiligten Personen in 11 Arbeitsgruppen überarbeitet. Der Einfluss von Interessenkonflikten (COI) konnte durch ein sorgfältiges COI-Management minimiert werden. Über die 80 Leitlinienempfehlungen diskutierten Delegierte aus 50 Fachgesellschaften und stimmten in einem moderierten Konsensprozess online ab. Ergebnisse: Neben Empfehlungen zum Screening und zur Diagnostik nimmt die Leitlinie positiv Stellung zur Nutzung niederschwelliger Beratungs- und Unterstützungsangebote. Falls aufgrund des Schweregrads der tabakbezogenen Störung Kurzberatung, Telefonberatung oder Internet- bzw. Smartphone-gestützte Verfahren nicht hinreichend wirksam sind, ist eine verhaltenstherapeutisch basierte Einzel- oder Gruppenbehandlung, ggf. in Verbindung mit Medikamenten, indiziert. Wenn eine Nikotinersatztherapie nicht wirksam sein sollte, soll Vareniclin oder Bupropion angeboten werden. Alternative Strategien mit niedrigerem Empfehlungsgrad sind Hypnotherapie, achtsamkeitsbasierte Verfahren, oder auch Cytisin. Bei Jugendlichen und Schwangeren ist das Angebot von Medikamenten auf genau spezifizierte Ausnahmen und Nikotinersatz zu beschränken. Die mittlere Zustimmung für die Empfehlungen der Leitlinie erreichte 98 %. Eine Gesamtübersicht über die Behandlungsempfehlungen der Tabakleitlinie geben drei klinische Algorithmen.

Better air but not for all? Changes in second-hand smoke exposure at workplaces in 29 European countries over 10 years

BACKGROUND

As the largest study of its kind to date, this article aims to describe the scope, trends over time, socio-demographic risk groups and the association with different progressive regulations relating to workplace second-hand smoke (SHS) exposure in 29 European countries during a period of high regulatory action.

METHODS

Three waves of the European Working Conditions Surveys (2005, 2010 and 2015) were evaluated, including a total of 95 718 workers. The samples are representative for all employed residents of the 29 countries included. All interviews were conducted face-to-face at respondents' homes (computer-assisted personal interviews). SHS exposure among the overall working population of 29 countries-including smokers-was examined. Workplace regimes were grouped corresponding to the sub-scale 'workplace' as used in the Tobacco Control Scale.

RESULTS

Between 2005 and 2015, SHS exposure in the European countries declined from around 19.0% (95% CI 16.1-22.0) to 9.9% (8.3-11.5). High SHS-exposure was reported by workers with the lowest level of education [11.5% (9.7-13.2)], among high-skilled manual labourers [14.3% (12.1-16.4)] and among those without a standard employment contract [11.2% (9.3-13.1)]. The highest exposure was reported by workers in the food service industry [19.7% (16.8-22.6)]. Countries with less workplace-related smoking prevention regulations were found to have the highest overall levels of exposure.

CONCLUSION

This multinational series of cross-sectional surveys on the trends in passive smoking in the workplace have shown that countries with more comprehensive workplace smoking bans overall report lower levels of SHS exposure among their work force as compared with slow progressing countries.

Association between income and education with quit attempts, use of cessation aids, and short-term success in tobacco smokers: A social gradient analysis from a population-based cross-sectional household survey in Germany (DEBRA study)

INTRODUCTION

Smoking is more prevalent in smokers from lower compared with higher socioeconomic (SES) groups, but studies are inconsistent regarding underlying mechanisms. We aimed to assess associations between SES indicators and three distinct aspects of the smoking cessation process: attempting to quit; use of evidence-based cessation treatments; and success.

METHODS

We analysed data of 12,161 last-year smokers (i.e., current smokers and recent ex-smokers who quit ≤ 12 months) from 20 waves (June/July 2016 to August/September 2019) of the German Study on Tobacco Use (DEBRA) - a representative household survey. Associations between indicators of SES (income and education) and (1) last-year quit attempts; (2) use of evidence-based cessation treatment or electronic cigarettes during the last attempt; and (3) short-term self-reported abstinence were analysed using multivariable logistic regression, adjusted for potential confounders.

RESULTS

Of all last-years smokers, 18.6% had attempted to quit, of whom 15.2% had successfully stopped. Higher income (OR 0.82, 95%CI = 0.77-0.88 per 1000€) but low vs. high education (OR 0.83, 95%CI = 0.73-0.95) were associated with lower odds of quit attempts. In smokers with quit attempts, higher income but not education was associated with higher odds of using cessation medication (OR 1.31, 95%CI = 1.08-1.59 per 1000 €). Neither income nor education were associated with using behavioural support or success.

CONCLUSIONS

In the German healthcare system without free access to evidence-based cessation therapy, low-income smokers are more likely to make a quit attempt but less likely to use cessation medication than high-income smokers. Equitable access to such medication is crucial to reduce SES-related health disparities.

Waterpipe use and associated consumer characteristics in the German population: Data from a national representative survey (DEBRA study)

BACKGROUND

Waterpipes (WP) have a long tradition in certain regions of the world, and their use has been increasing worldwide. Current data on the use of WP in different subgroups of the German population are missing.

OBJECTIVE

To estimate the current prevalence of WP use and associated socio-demographic characteristics, tobacco smoking status and e-cigarette usage behaviour in the German population aged ≥14 years; to describe the frequency of use and starting age in current WP users.

METHODS

We analysed data from waves 13-18 (June/July 2018-April/May 2019; N = 12,220) of the German Study on Tobacco Use (DEBRA) - a representative, computer-assisted national household survey. Associations of socio-demographic characteristics, tobacco smoking status and e-cigarette usage behaviour were assessed with multivariable logistic regression models.

RESULTS

A total of 1.8% (n = 217) (95% confidence interval (CI) = 1.5%-2.0%) of the population were current WP users, 13% (n = 1618) (95% CI = 12.3%-13.5%) were ever users. Adjusted multivariable logistic models showed that people with migration background, male sex, younger age, and those who were smokers or used e-cigarettes, were more likely to use a WP. Among current WP users, 15.2% (n = 33) (95% CI = 10.7%-20.7%) had started to use WP at the age of 26 or older, and 23.0% (n = 50) (95%CI = 17.6%-29.2%) had used WP at least once a week or almost daily in the last month.

CONCLUSIONS

In Germany, the use of WP is popular and most strongly associated with migration background and use of tobacco and e-cigarettes. These aspects should be considered when designing future target group-specific prevention strategies.

Waterpipe Use among Adolescents in Germany: Prevalence, Associated Consumer Characteristics, and Trends (German Health Interview and Examination Survey for Children and Adolescents, KiGGS)

Waterpipe (WP) use is popular among youth worldwide, but epidemiological data from Germany are scarce. We aimed to describe prevalence rates of WP use (current, last 12 months, ever) and analysed correlates and trends among 11- to 17-year-olds in Germany. Analyses were based on data from the "German Health Interview and Examination Survey for Children and Adolescents" study during 2014-2017 (n = 6599). Changes in WP use prevalence compared with 2009-2012 were used to describe trends. Associations with sociodemographic characteristics and cigarette smoking were assessed with multivariable logistic regression models. Prevalence of current WP use among adolescents was 8.5% (95% confidence interval (CI) = 7.5-9.6), use in the last 12 months was 19.7% (95% CI = 18.3-21.2), and ever use was 25.8% (95% CI = 24.2-27.5). High prevalence rates were particularly found among 16-17-year-olds. During 2009-2012, these prevalence rates were 9.0%, 18.5%, and 26.1%, respectively. WP use was associated with older age, male sex, migration background, lower educational level, and current smoking status. Among current WP users, 66.2% (95% CI = 60.0-71.9) identified themselves as non-smokers, and 38.1% (95% CI = 32.5-44.0) had used WP ≥ three times in the last month. WP consumption is popular among German youth, and prevalence rates have not changed over time. Specific prevention strategies to reduce harmful WP consumption among youth should be implemented.

Smoking Cessation Attempts and Common Strategies Employed

BACKGROUND

Clinical guidelines on smoking cessation contain recommendations for various evidence-based methods. The goal of this study was to provide a represen- tative analysis for Germany of the percentage of smokers who try to quit smoking at least once per year, the use of evidence-based methods and other methods of smoking cessation, and potential associations of the use of such methods with the degree of tobacco dependence and with socioeconomic features.

METHODS

Data from 19 waves of the German Smoking Behavior Questionnaire (Deutsche Befragung zum Rauchverhalten, DEBRA), from the time period June/July 2016 to June/July 2019, were analyzed. Current smokers and recent ex-smokers (<12 months without smoking) were asked about their smoking cessation attempts in the past year and the methods they used during the last attempt (naming more than one method was permitted). The degree of tobacco dependence in current smokers was assessed with the Heaviness of Smoking Index.

RESULTS

Out of 11 109 current smokers and 407 recent ex-smokers, 19.9% (95% confidence interval: [19.1; 20.6]) had tried to quit smoking at least once in the preceding year. 13.0% of them [11.6; 14.5] had used at least one evidence-based method during their last attempt. The stronger the tobacco dependence, the more likely the use of an evidence-based method (odds ratio [OR] = 1.27 [1.16; 1.40]). Pharmacotherapy (nicotine replacement therapy, medication) was used more com- monly by persons with higher incomes (OR = 1.44 per 1000 euro/month [1.28; 1.62]). Electronic cigarettes were the most commonly used single type of smoking cessation support (10.2 % [9.0; 11.6]).

CONCLUSION

In Germany, only one in five smokers tries to quit smoking at least once per year. Such attempts are only rarely supported by evidence-based methods and are thus likely to fail. The high cost of treatment must be borne by the individual and thus fall disproportionately on poorer smokers. It follows that there is an urgent need for vered by health insurance pro- viders, in order to give all smokers fair and equal access to the medical care they need.

Electronic Cigarettes to Vaporize Cannabis: Prevalence of Use and Associated Factors among Current Electronic Cigarette Users in Germany (DEBRA Study)

Background: In Germany, cannabis is the most widely used illicit drug, and inhalation together with tobacco is most popular. However, it has been described that electronic cigarettes (ECs) are being used to vaporize cannabis (extract). No current data on EC cannabis use in the German population are yet available. Objectives: This study examines the prevalence of EC cannabis consumption for mood changing effects among current EC users, and associated consumer characteristics in Germany. Methods: We used data from the German Study on Tobacco Use (period: 8/2016-01/2019, DEBRA, www.debra-study.info), a nationally representative household survey. EC cannabis use for mood-changing effects was assessed in 504 current EC users (aged ≥ 18 years) of the total sample (N = 32,678). Ever use was defined by: (1) occasional or regular use, or (2) experimental consumption. Associations with socio-demographic consumer characteristics and tobacco smoking were analyzed using multivariable regression analyses. Results: Amongst current EC users, 7.2% had ever vaporized cannabis: 2.3% (95%CI = 1.2-3.9) reported occasional or regular use (1) and 4.8% (95%CI = 3.2-7.1) reported experimental use (2). Age was associated with ever EC cannabis use: highest prevalence rates were found among 18-24-year-olds: 6.5% (95%CI = 2.3-13.1) (1) and 8.0% (95%CI = 3.7-15.8) (2), respectively. The majority (90.2%) of ever EC cannabis users were current tobacco smokers. Conclusions: One in 14 current EC users in Germany has ever vaporized cannabis for mood-changing reasons, and almost all EC cannabis consumers also smoke tobacco. Highest usage rates can be observed among young adults. Hence, trends of EC drug misuse need to be monitored consequently, particularly in young people.

[Should advertising for electronic cigarettes and heated tobacco products be banned in Germany? Results of a representative survey (DEBRA study)]

BACKGROUND

The German federal parliament is discussing the implementation of a comprehensive tobacco advertising ban and whether that ban should include alternative nicotine delivery systems (ANDSs), such as e‑cigarettes and tobacco heaters. It would be important to know which outcome the general population, and in particular the users of tobacco/ANDSs, would prefer.

OBJECTIVE

Assessing public support for a comprehensive advertising ban on ANDSs in the German population, and particularly in tobacco and ANDSs users.

MATERIAL AND METHODS

The German Study on Tobacco Use ("Deutsche Befragung zum Rauchverhalten", DEBRA) is an ongoing, representative household survey of persons aged 14 years and older. Data from the June/July 2019 survey wave (n = 2019) were analysed. Participants were interviewed regarding their tobacco smoking status and ANDS use, sociodemographic factors, and their support of an advertising ban on ANDSs. Prevalence rates and associations (odds ratio, OR) between support and sociodemographic factors or use of tobacco/ANDSs are reported.

RESULTS

Of the population, 57.0% (95% confidence interval (95%CI) = 54.7-59.1%) support a ban on ANDS advertising; 11.1% (95%CI = 9.8-12.6%) reject it. There is support for the ban from 46.0% (95%CI = 42.2-49.9%) of current tobacco smokers and 42.7% (95%CI = 35.9-49.6%) of ANDS users. Ex-smokers show the highest rates of support (64.8%, 95%CI = 58.9-70.3%). Acceptance among never- and ex-smokers is higher than among current smokers (adjusted OR 2.06, 95%CI = 1.64-2.59 and OR 1.65, 95%CI = 1.23-2.21).

CONCLUSIONS

The majority of the German population supports a comprehensive advertising ban on ANDSs. Tobacco smokers and ANDS users are also more in favour of than against such a ban. Thus, only little resistance will be expected within the population if a comprehensive tobacco advertising ban, as currently discussed in parliament, includes e‑cigarettes and heated tobacco products.

Health worker and patient views on implementation of smoking cessation in routine tuberculosis care

Smoking worsens tuberculosis (TB) outcomes. Persons with TB who smoke can benefit from smoking cessation. We report findings of a multi-country qualitative process evaluation assessing barriers and facilitators to implementation of smoking cessation behaviour support in TB clinics in Bangladesh and Pakistan. We conducted semi-structured qualitative interviews at five case study clinics with 35 patients and 8 health workers over a period of 11 months (2017-2018) at different time points during the intervention implementation phase. Interviews were conducted by trained researchers in the native languages, audio-recorded, transcribed into English and analysed using a combined deductive-inductive approach guided by the Consolidated Framework for Implementation Research and Theoretical Domains Framework. All patients report willingness to quit smoking and recent quit attempts. Individuals' main motivations to quit are their health and the need to financially provide for a family. Behavioural regulation such as avoiding exposure to cigarettes and social influences from friends, family and colleagues are main themes of the interviews. Most male patients do not feel shy admitting to smoking, for the sole female patient interviewee stigma was an issue. Health workers report structural characteristics such as high workload and limited time per patient as primary barriers to offering behavioural support. Self-efficacy to discuss tobacco use with women varies by health worker. Systemic barriers to implementation such as staff workload and socio-cultural barriers to cessation like gender relations, stigma or social influences should be dealt with creatively to optimize the behaviour support for sustainability and scale-up.

Moderators of real-world effectiveness of smoking cessation aids: a population study

BACKGROUND AND AIMS

Understanding whether and how far smokers' characteristics influence the effectiveness of treatment may be important for tailoring recommendations on cessation aids to those most likely to help the user achieve abstinence. This study aimed to estimate the effectiveness of commonly used smoking cessation aids and test whether their effectiveness differs according to cigarette addiction, socio-economic status, age or sex.

DESIGN

Correlational design using cross-sectional survey data collected monthly between 2006 and 2018.

SETTING

England.

PARTICIPANTS

A total of 18 929 adults (aged ≥ 16 years, 52.0% female) who had smoked within the previous 12 months and had made at least one quit attempt during that period.

MEASUREMENTS

The outcome was self-reported abstinence from quit date to survey. Independent variables were self-reported use during the most recent quit attempt of: prescription nicotine replacement therapy (NRT), NRT over-the-counter, varenicline, bupropion, e-cigarettes, face-to-face behavioural support, telephone support, written self-help materials, websites and hypnotherapy. Moderators were cigarette addiction, social grade, age and sex.

FINDINGS

After adjustment for covariates and use of other cessation aids, users of e-cigarettes [odds ratio (OR) = 1.95, 95% confidence interval (CI) = 1.69-2.24] and varenicline (OR = 1.82, 95% CI = 1.51-2.21) had significantly higher odds of reporting abstinence than those who did not report use of these cessation aids. Use of prescription NRT was associated with increased abstinence in older (≥ 45 years) (OR = 1.58, 95% CI = 1.25-2.00) but not younger (< 45 years) smokers (OR = 1.09, 95% CI = 0.85-1.42). Use of websites was associated with increased abstinence in smokers from lower (OR = 2.20, 95% CI = 1.22-3.98) but not higher social grades (OR = 0.74, 95% CI = 0.40-1.38). There was little evidence of benefits of using other cessation aids.

CONCLUSIONS

Use of e-cigarettes and varenicline are associated with higher abstinence rates following a quit attempt in England. Use of prescription of nicotine replacement therapy is also associated with higher abstinence rates, but only in older smokers, and use of websites only in smokers from lower socio-economic status.

Public attitudes towards healthcare policies promoting tobacco cessation in Germany: results from the representative German study on tobacco use (DEBRA study)

OBJECTIVE

The aim of this study was to assess public acceptance of four possible healthcare policies supporting tobacco dependence treatment in line with the Framework Convention for Tobacco Control, Article 14 recommendations in Germany.

DESIGN

Cross-sectional household survey.

SETTING

Data were drawn from the German population and collected through computer-assisted, face-to-face interviews.

PARTICIPANTS

Representative random sample of 2087 people (>14 years) from the German population.

OUTCOME MEASURES

Public acceptance was measured regarding (1) treatment cost reimbursement, (2) standard training for health professionals on offering cessation treatment, and making cessation treatment a standard part of care for smokers with (3) physical or (4) mental disorders. Association characteristics with smoking status and socio-economic status (SES) were assessed.

RESULTS

Support for all policies was high (50%-68%), even among smokers (48%-66%). Ex-smokers and never-smokers were more likely to support standard training on cessation for health professionals than current smokers (OR 1.43, 95% CI 1.07 to 1.92; OR 1.43; 95% CI 1.14 to 1.79, respectively). Ex-smokers were also more likely than current smokers to support cessation treatment for smokers with mental disorders (OR 1.39, 95% CI 1.11 to 1.73). Men were less likely than women to support cessation treatment for smokers with physical diseases (OR 0.74, 95% CI 0.60 to 0.91) and free provision of treatment (OR 0.80, 95% CI 0.66 to 0.97). Offering cessation treatment to smokers with physical disorders was generally more accepted than to those with mental health issues.

CONCLUSIONS

The majority of the German population supports healthcare policies to improve the availability and affordability of tobacco dependence treatment. Non-smokers were more supportive than current smokers of two of the four policies, but odds of support were only about 40% higher. SES characteristics were not consistently associated with public acceptance.

Effectiveness of training general practitioners to improve the implementation of brief stop-smoking advice in German primary care: study protocol of a pragmatic, 2-arm cluster randomised controlled trial (the ABCII trial)

Background

The German clinical guideline on tobacco addiction recommends that general practitioners (GPs) provide brief stop-smoking advice to their patients according to the “5A” or the much briefer “ABC” method, but its implementation is insufficient. A lack of training is one barrier for GPs to provide such advice. Moreover, the respective effectiveness of a 5A or ABC training regarding subsequent delivery of stop-smoking advice has not been investigated. We developed a training for GPs according to both methods, and conducted a pilot study with process evaluation to optimize the trainings according to the needs of GPs. This study aims at evaluating the effectiveness of both trainings.

Methods

A pragmatic 2-arm cluster randomised controlled trial with a pre-post data collection will be conducted in 48 GP practices in North Rhine-Westphalia (Germany). GPs will be randomised to receive a 3.5-h-training in delivering either 5A or ABC, including peer coaching and intensive role plays with professional actors. The patient-reported primary outcome (receipt of GP advice to quit: yes/no) and secondary outcomes (recommendation rates of smoking cessation treatments, group comparison (5A versus ABC): receipt of GP advice to quit) will be collected in smoking patients routinely consulting their GP within 4 weeks prior, and 4 weeks following the training. Additional secondary outcomes will be collected at 4, 12 and 26 weeks following the consultation: use of cessation treatments during the last quit attempt (if so) since the GP consultation, and point-prevalence abstinence rates. The primary data analysis will be conducted using a mixed-effects logistic regression model with random effects for the cluster variable.

Discussion

If the training increases the rates of delivery of stop-smoking advice, it would offer a low-threshold strategy for the guideline implementation in German primary care. Should one method prove superior, a more specific guideline recommendation can be proposed.

Recommendations on how to achieve tobacco-free nations in Europe

European countries vary widely in the development and implementation of effective tobacco-control programs and policies. Why some countries lag behind others is inherently a political matter. National-level policymakers struggle between the need to protect public health and the need to recognize economic and ideological considerations. Within this context, use of scientific evidence plays an important role in the policy making process. Articles 20 and 22 of the World Health Organisation's Framework Convention of Tobacco Control (FCTC) oblige countries to develop and coordinate research on aspects of tobacco control and require of them to facilitate knowledge transfer and capacity building between countries. This paper considers various ways how EU and national policy makers may accomplish this. We conclude that progress in three areas is needed: 1) generation of more scientific evidence relevant for each country; 2) facilitation of policy learning between countries; and 3) building capacity and collaborations between researchers and tobacco-control advocates to bridge the gap from research to policy, especially in countries with weak tobacco-control infrastructures.

Ärztliche Kurzberatung zur Tabakentwöhnung – Ergebnisse der DEBRA Studie

Zusammenfassung. Zielsetzung: Klinische Leitlinien empfehlen ärztliche Kurzberatung zur Tabakentwöhnung routinemäßig anzubieten. Repräsentative Daten zur Umsetzung in Deutschland und zu Assoziationen mit Soziodemographie und Rauchverhalten von Raucher/innen sollen erhoben werden. Methoden: Die Deutsche Befragung zum Rauchverhalten (DEBRA) erhebt zweimonatlich Daten in repräsentativen Bevölkerungsstichproben (je ~2.000 Personen, ≥14 Jahre) zu Tabak- und E-Zigarettenkonsum. In den ersten fünf Wellen seit Juni 2016 (10.225 Befragte) wurden Raucher/innen zu dem Erhalt von Rauchstoppberatung während des letzten Besuchs bei einer Hausärztin/einem Hausarzt (A) oder einer Ärztin/einem Arzt anderer Fachrichtung (B) befragt. Assoziationen mit Soziodemographie und Rauchverhalten wurden analysiert. Ergebnisse: Nach eigener Aussage von 2.910 Raucher/innen, hatten 72,8 % (95 %KI=71–74 %) eine Ärztin/einen Arzt des Fachgebiets A und/oder B konsultiert. Davon hatten 80,7 % (95 %KI=79–82 %) keine Rauchstoppempfehlung erhalten. 3,6 % (95 %KI=3–5 %) hatten ein evidenzbasiertes Therapieangebot bekommen. Starker Zigarettenkonsum und steigendes Alter waren mit dem Erhalt der Kurzberatung assoziiert (P<0,001), aber Bildung und Einkommen nicht. Es gab kaum Unterschiede zwischen Fachrichtung A und B. Schlussfolgerung: Der Erhalt leitliniengerechter ärztlicher Kurzberatung zur Tabakentwöhnung wird von Raucher/innen in Deutschland selten berichtet. Dringender Handlungsbedarf zur verbesserten Umsetzung der Leitlinienempfehlung besteht.

Construct and Predictive Validity of Three Measures of Intention to Quit Smoking: Findings From the International Tobacco Control (ITC) Netherlands Survey

Introduction

The aim of the study was to compare the construct validity and the predictive validity of three instruments to measure intention to quit smoking: a Stages of Change measure, the Motivation To Stop Scale (MTSS), and a Likert scale. We used the Theory of Planned Behavior as theoretical framework.

Methods

We used data from the International Tobacco Control Netherlands Survey. We included smokers who participated in three consecutive survey waves (n = 980). We measured attitude, subjective norm, and perceived behavioral control in 2012, intention to quit with three instruments in 2013, and having made a quit attempt in the last year in 2014. We conducted Structural Equation Modeling with three models for the instruments of intention separately and with one model that included the three instruments simultaneously.

Results

All three instruments of intention were significantly and positively related to attitude and perceived behavioral control but none was related to subjective norm. All three instruments were significantly and positively related to making a quit attempt. The relation of the Likert scale with making a quit attempt (β = 0.38) was somewhat stronger than that of the Stages of Change measure (β = 0.35) and the MTSS (β = 0.22). When entering the three instruments together into one model, only the Likert scale was significantly related to making a quit attempt.

Conclusions

All three instruments showed reasonable construct validity and comparable predictive validity. Under the studied conditions, the Likert scale performed slightly better than the Stages of Change measure and the MTSS.

Implications

An assessment of the Stages of Change, the Motivation To Stop Scale, and a Likert scale showed comparable predictive and construct validity as measures for intention to quit smoking. All three instruments can be used in future research; however, under the studied theoretical framework, that is, the Theory of Planned Behavior, the Likert scale performed slightly better than the other two instruments.
