Feasibility of Rehabilitation during Chemoradiotherapy among Patients with Stage III Non-Small Cell Lung Cancer: A Proof-of-Concept Study

Rehabilitation during chemoradiotherapy (CHRT) might (partly) prevent reduction in physical fitness and nutritional status and could improve treatment tolerance in patients with stage III non-small cell lung cancer (NSCLC). The aim of this proof-of-concept study was to investigate the feasibility of a multimodal program for rehabilitation during CHRT. A home-based multimodal rehabilitation program (partly supervised moderate-intensity physical exercise training and nutritional support) during CHRT was developed in collaboration with patients with stage III NSCLC and specialized healthcare professionals. A predetermined number of six patients with stage III NSCLC (aged > 50 years) who underwent CHRT and participated in this program were monitored in detail to assess its feasibility for further development and optimization of the program. The patient’s level of physical functioning (e.g., cardiopulmonary exercise test, six-minute walking test, handgrip strength, body mass index, fat free mass index, energy and protein intake) was evaluated in order to provide personalized advice regarding physical exercise training and nutrition. The program appeared feasible and well-tolerated. All six included patients managed to perform the assessments. Exercise session adherence was high in five patients and low in one patient. The performed exercise intensity was lower than prescribed for all patients. Patients were motivated to complete the home-based rehabilitation program during CHRT. Preliminary effects on physical and nutritional parameters revealed relatively stable values throughout CHRT, with inter-individual variation. Supervised and personalized rehabilitation in patients with stage III NSCLC undergoing CHRT seems feasible when the intensity of the physical exercise training was adjusted to the possibilities and preferences of the patients. Future research should investigate the feasibility of a supervised and personalized rehabilitation program during CHRT with a low-to-moderate exercise intensity with the aim to prevent physical decline during CHRT.

[Factors associated with medical residents' brief counseling]

INTRODUCTION

Smoking is a public health problem. Physicians have an important role in the fight against smoking, particularly by means of the brief advice they can give. The aim of this work was to study the prevalence of brief advice application by medical residents and to identify factors that may condition its practice.

METHODS

We conducted a descriptive and analytical study with prospective data collection that included 302 residents practicing in Tunisia who had agreed to respond to an online questionnaire submitted in February and March 2020.

RESULTS

Residents' mean age was 28±2 years and the gender ratio was 0.65. Sixty-four percent of them were non-smokers. During their practice, 94% systematically identified their patients' smoking status, but 61.9% were unfamiliar with the concept of brief advice. Residents' brief advice application rate was 57.6%. In multivariate analysis, the factors impacting brief advice application were: gender (OR=0.321, p=0.0001), familiarity with brief counseling (OR=2.808, p=0.002) and having observed brief advice being given by a senior physician (OR=2.328, p=0.0001).

CONCLUSION

The rate of brief advice application remains low. On this subject, improved theoretical and practical teaching during medical studies is essential.

Smoking Prevalence among Physicians: A Systematic Review and Meta-Analysis

BACKGROUND

Smoking is a major public health problem. Although physicians have a key role in the fight against smoking, some of them are still smoking. Thus, we aimed to conduct a systematic review and meta-analysis on the prevalence of smoking among physicians.

METHODS

PubMed, Cochrane, and Embase databases were searched. The prevalence of smoking among physicians was estimated and stratified, where possible, by specialties, continents, and periods of time. Then, meta-regressions were performed regarding putative influencing factors such as age and sex.

RESULTS

Among 246 studies and 497,081 physicians, the smoking prevalence among physicians was 21% (95CI 20 to 23%). Prevalence of smoking was 25% in medical students, 24% in family practitioners, 18% in surgical specialties, 17% in psychiatrists, 16% in medical specialties, 11% in anesthesiologists, 9% in radiologists, and 8% in pediatricians. Physicians in Europe and Asia had a higher smoking prevalence than in Oceania. The smoking prevalence among physicians has decreased over time. Male physicians had a higher smoking prevalence. Age did not influence smoking prevalence.

CONCLUSION

Prevalence of smoking among physicians is high, around 21%. Family practitioners and medical students have the highest percentage of smokers. All physicians should benefit from targeted preventive strategies.

Facilitating smoking cessation in patients who smoke: a large-scale cross-sectional comparison of fourteen groups of healthcare providers

Background

Although healthcare providers are well placed to help smokers quit, implementation of smoking cessation care is still suboptimal. The Ask-Advise-Refer tasks are important aspects of smoking cessation care. We examined to which extent a large and diverse sample of healthcare providers expressed the intention to implement smoking cessation care and which barriers they encountered. We moreover examined to which extent the Ask-Advise-Refer tasks were implemented as intended, and which determinants (in interaction) influenced intentions and the implementation of Ask-Advise-Refer.

Methods

Cross-sectional survey among addiction specialists, anaesthesiologists, cardiologists, general practitioners, internists, neurologists, paediatricians, pulmonologists, ophthalmologists, surgeons, youth specialists, dental hygienists, dentists, and midwives (N = 883). Data were analysed using multivariate linear and logistic regression analyses and regression tree analyses.

Results

The Ask-Advice-Refer tasks were best implemented among general practitioners, pulmonologists, midwives, and addiction specialists. Overall we found a large discrepancy between asking patients about smoking status and advising smokers to quit. Participants mentioned lack of time, lack of training, lack of motivation to quit in patients, and smoking being a sensitive subject as barriers to smoking cessation care. Regression analyses showed that the most important determinants of intentions and implementation of Ask-Advise-Refer were profession, role identity, skills, guideline familiarity and collaboration agreements for smoking cessation care with primary care. Determinants interacted in explaining outcomes.

Conclusions

There is much to be gained in smoking cessation care, given that implementation of Ask-Advise-Refer is still relatively low. In order to improve smoking cessation care, changes are needed at the level of the healthcare provider (i.e., facilitate role identity and skills) and the organization (i.e., facilitate collaboration agreements and guideline familiarity). Change efforts should be directed towards the specific barriers encountered by healthcare providers, the contexts that they work in, and the patients that they work with.

Provider-Level Variation in Smoking Cessation Assistance Provided in the Cardiology Clinics: Insights From the NCDR PINNACLE Registry

Background Studies show suboptimal provision of smoking cessation assistance (counseling or pharmacotherapy) for current smokers attempting to quit. We aimed to identify smoking cessation assistance patterns in US cardiology practices. Methods and Results Among 328 749 current smokers seen between January 1, 2013, and March 31, 2016, in 348 NCDR (National Cardiovascular Data Registry) PINNACLE (Practice Innovation and Clinical Excellence)-affiliated cardiology practices, we measured the rates of cessation assistance. We used multivariable hierarchical logistic regression models to determine provider-, practice-, and patient-level predictors of cessation assistance. We measured provider variation in cessation assistance using median rate ratio (the likelihood that the same patient would receive the same assistance at by any given provider; >1.2 suggests significant variation). Smoking cessation assistance was documented in only 34% of encounters. Despite adjustment of provider, practice, and patient characteristics, there was large provider-level variation in cessation assistance (median rate ratio, 6 [95% CI , 5.76-6.32]). Practice location in the South region (odds ratio [OR], 0.48 [0.37-0.63] versus West region) and rural or suburban location (OR, 0.92 [0.88-0.95] for rural; OR, 0.94 [0.91-0.97] for suburban versus urban) were associated with lower rates of cessation assistance. Similarly, older age (OR, 0.88 [0.88-0.89] per 10-year increase), diabetes mellitus (OR, 0.84 [0.82-0.87]), and atrial fibrillation (OR, 0.93 [0.91-0.96]) were associated with lower odds of receiving cessation assistance. Conclusions In a large contemporary US registry, only 1 in 3 smokers presenting for a cardiology visit received smoking cessation assistance. Our findings suggest the presence of a large deficit and largely idiosyncratic provider-level variation in the provision of smoking cessation assistance.

[Smoking cessation: A challenge for cardiologists and pulmonologists]

In addition to public health measures that need to be strongly supported politically, smoking is also a major medical issue. Tobacco dependence is a chronic disease, and, given its extremely addictive nature, treatment for tobacco dependence must be addressed actively by all health professionals. Because smoking is a major contributor to many of the pathologies their specialties address, cardiologists and pulmonologists must be at the forefront of this care. In this review we analyse the current state of smoking cessation treatment and its inadequacies, the limiting impact that doctors' own smoking has, as well as the misconceptions held by smokers and sometimes by doctors as well, which act as brakes on smoking cessation. Smoking cessation must become a treatment delivered in real clinical practice and any doctor must know how to manage it fluently. Do not be satisfied with simply advising smokers to quit. Learn how to approach the subject with smokers effectively, know how the various pharmacotherapies are used and know how to organize smoking cessation follow-up, an essential guarantee of success. If optimal management of this major pathological factor is a role for all doctors, it is of course especially so for our two specialties. It's up to us, cardiologists and pulmonologists, to take up this challenge.

Knowledge, attitude, and behaviors of health professionals towards smoking cessation in primary healthcare settings

This study aimed to assess the behaviors of multiple health professionals in primary healthcare settings in Jordan towards smoking cessation counseling and to determine the barriers to effective smoking cessation behaviors. A survey of 456 health professionals in primary healthcare settings was conducted. A self-administrated questionnaire was used to collect the data. About half of health professionals reported that they usually ask patients about smoking status and advise them to stop smoking (51.4% and 50.5%, respectively). Only 23.7% reported assessing the willingness of the patients to quit smoking and 17.9% reported discussing counseling options with smokers. Considerably fewer percentages of health professionals reported preparing their patients for withdrawal symptoms (6.0%), discussing pharmacotherapies (3.8%), and prescribing nicotine patches (6.4%). Key barriers to smoking cessation counseling, as reported by health professionals, included: insufficient resources and organizational support, limited coverage of cessation interventions, and lack of motivation to quit. Smoking cessation counseling was not routinely implemented by Jordanian health professionals. Barriers to effective delivery of smoking cessation counseling need to be integrated within relevant strategies aiming at enhancing the frequency and quality of health professionals' engagement in smoking cessation.

Use of Expired Air Carbon Monoxide Testing in Clinical Tobacco Treatment Settings

Carbon monoxide (CO) testing is considered an easy, noninvasive, and objective contribution to the assessment of smoking behavior, as CO is rapidly absorbed into the bloodstream when lit cigarettes or cigars are inhaled. CO testing is a medically important billable outpatient service that can contribute to sustainability of face to face tobacco use treatment services by clinicians. This article reviews research on the clinical use of CO testing to provide biomedical feedback in assessing smoking behavior, educating smokers on tobacco health effects, assisting with treatment planning, and as a motivational tool to encourage people to become tobacco free. Further research can focus on how to best incorporate CO testing into clinical practice, including more research on outcomes and methods to ensure that insurers reimburse for testing and improved ways to use CO testing to initiate attempts to quit tobacco use, to maintain cessation, and to prevent relapse.

Combining intensive practice nurse counselling or brief general practitioner advice with varenicline for smoking cessation in primary care: study protocol of a pragmatic randomized controlled trial

INTRODUCTION

Combining behavioural support and pharmacotherapy is most effective for smoking cessation and recommended in clinical guidelines. Despite that smoking cessation assistance from the general practitioner can be effective, dissemination of clinical practice guidelines and efforts on upskilling has not lead to the routine provision of smoking cessation advice among general practitioners. Intensive counselling from the practice nurse could contribute to better smoking cessation rates in primary care. However, the effectiveness of intensive counselling from a practice nurse versus usual care from a general practitioner in combination with varenicline is still unknown.

MATERIALS AND METHODS

A pragmatic randomized controlled trial was conducted comparing: (a) intensive individual counselling delivered by a practice nurse and (b) brief advice delivered by a general practitioner; both groups received 12-weeks of open-label varenicline. A minimum of 272 adult daily smoking participants were recruited and treated in their routine primary care setting. The primary outcome was defined as prolonged abstinence from weeks 9 to 26, biochemically validated by exhaled carbon monoxide. Data was analysed blinded according to the intention-to-treat principle and participants with missing data on their smoking status at follow-up were counted as smokers. Secondary outcomes included: one-year prolonged abstinence, short-term incremental cost-effectiveness, medication adherence, and baseline predictors of successful smoking cessation.

DISCUSSION

This trial is the first to provide scientific evidence on the effectiveness, cost-effectiveness, and potential mechanisms of action of intensive practice nurse counselling combined with varenicline under real-life conditions. This paper explains the methodology of the trial and discusses the pragmatic and/or explanatory design aspects.

Are primary care physicians prepared to assist patients for smoking cessation? Results of a national Italian cross-sectional web survey

OBJECTIVE

The primary purpose of this study is to explore primary care physicians' (PCPs') knowledge, attitudes and self-reported activities provided to patients for smoking cessation. The secondary purpose is to identify the relationships between physician-related characteristics and knowledge, attitudes and self-reported activities for smoking cessation.

METHOD

A national cross-sectional web survey was conducted in Italy from April through September 2012.

RESULTS

722 PCPs completed the questionnaire. The great majority indicated the correct proportion of smokers among patients with lung cancer, the smoking abstention required for risk reduction after smoking cessation, and tobacco as a known major risk factor for chronic obstructive pulmonary disease (COPD), whereas 28.7% knew the Fagerstrom test for the assessment of nicotine dependence. Almost all PCPs reported that they ask all patients if they smoke, inform about the dangers of smoking and recommend to quit smoking, whereas prescription of recommended drugs for smoking cessation varied from 37.7% for nicotine replacement therapy to 4.9% for varenicline.

CONCLUSION

Despite a positive attitude, Italian PCPs are not prepared to deliver effective interventions for smoking cessation in their patients.

Effectiveness of a telephone delivered and a face-to-face delivered counseling intervention for smoking cessation in patients with coronary heart disease: a 6-month follow-up

Smoking cessation interventions for cardiac patients need improvement given their weak effects on long-term abstinence rates and low compliance by nurses to implementation. This study tested the effectiveness of two smoking cessation interventions against usual care in cardiac patients, and conditional effects for patients' motivation to quit and socio-economic status (SES). An experimental study was conducted from 2009 to 2012 for which Dutch cardiac patient smokers were assigned to: usual care (UC; n = 245), telephone counseling (TC; n = 223) or face-to-face counseling (FC; n = 157). The three groups were comparable at baseline and had smoked on average 21 cigarettes a day before hospitalization. After six months, interviews occurred to assess self-reported smoking status. Patients in the TC and FC group had significantly higher smoking abstinence rates than patients in the UC group (p ≤ 0.05 at all times). Regression analysis further revealed significant conditional effects of the interventions on smoking abstinence in patients with lower SES, with a larger effect for TC than FC when compared to UC. These findings suggest that intensive counseling is effective in increasing short-term abstinence rates, particularly in patients with lower SES. Future studies need to investigate how patients with higher SES can profit equally from these type of interventions.

Smoking cessation treatment practices: recommendations for improved adoption on cardiology wards

BACKGROUND AND OBJECTIVES

Smoking cessation treatment practices described by the 5 A's (ask, advise, assess, assist, arrange) are not well applied at cardiology wards because of various reasons, such as a lack of time and appropriate skills of the nursing staff. Therefore, a simplified guideline proposing an ask-advise-refer (AAR) strategy was introduced in Dutch cardiac wards. This study aimed to identify factors that determine the intentions of cardiac ward heads in adopting the simplified AAR guideline, as ward heads are key decision makers in the adoption of new guidelines. Ward heads' perceptions of current smoking cessation practices at the cardiac ward were also investigated.

METHODS

A cross-sectional survey with written questionnaires was conducted among heads of cardiology wards throughout the Netherlands, of whom 117 (64%) responded.

RESULTS

According to the heads of cardiac wards, smoking cessation practices by cardiologists and nurses were mostly limited to brief practices that are easy to conduct. Only a minority offered intensive counseling or arranged follow-up contact. Heads with strong intentions of adopting the AAR guideline differed significantly on motivational and organizational attributes and perceived more smoking cessation assistance by other health professionals than did heads with weak intentions of adopting. Positive attitudes, social support toward adoption, and perception of much assistance at the ward were significantly associated with increased intentions to adopt the AAR guideline.

CONCLUSIONS

Brief smoking cessation practices are adequately performed at cardiac wards, but the most effective practices, offering assistance and arranging for follow-up, are less than optimal. The AAR guideline offers a more feasible approach for busy cardiology wards. To ensure successful adoption of this guideline, the heads of cardiac wards should be convinced of its advantages and be encouraged by a supportive work environment. Policies may also facilitate the adoption of the AAR guideline.

Effectiveness of two intensive treatment methods for smoking cessation and relapse prevention in patients with coronary heart disease: study protocol and baseline description

BACKGROUND

There is no more effective intervention for secondary prevention of coronary heart disease than smoking cessation. Yet, evidence about the (cost-)effectiveness of smoking cessation treatment methods for cardiac inpatients that also suit nursing practice is scarce. This protocol describes the design of a study on the (cost-)effectiveness of two intensive smoking cessation interventions for hospitalised cardiac patients as well as first results on the inclusion rates and the characteristics of the study population.

METHODS/DESIGN

An experimental study design is used in eight cardiac wards of hospitals throughout the Netherlands to assess the (cost-)effectiveness of two intensive smoking cessation counselling methods both combined with nicotine replacement therapy. Randomization is conducted at the ward level (cross-over). Baseline and follow-up measurements after six and 12 months are obtained. Upon admission to the cardiac ward, nurses assess patients' smoking behaviour, ensure a quit advice and subsequently refer patients for either telephone counselling or face-to-face counselling. The counselling interventions have a comparable structure and content but differ in provider and delivery method, and in duration. Both counselling interventions are compared with a control group receiving no additional treatment beyond the usual care. Between December 2009 and June 2011, 245 cardiac patients who smoked prior to hospitalisation were included in the usual care group, 223 in the telephone counselling group and 157 in the face-to-face counselling group. Patients are predominantly male and have a mean age of 57 years. Acute coronary syndrome is the most frequently reported admission diagnosis. The ultimate goal of the study is to assess the effects of the interventions on smoking abstinence and their cost-effectiveness. Telephone counselling is expected to be more (cost-)effective in highly motivated patients and patients with high SES, whereas face-to-face counselling is expected to be more (cost-)effective in less motivated patients and patients with low SES.

DISCUSSION

This study examines two intensive smoking cessation interventions for cardiac patients using a multi-centre trial with eight cardiac wards. Although not all eligible patients could be included and the distribution of patients is skewed in the different groups, the results will be able to provide valuable insight into effects and costs of counselling interventions varying in delivery mode and intensity, also concerning subgroups.

Smoking counseling practices of physicians in the United Arab Emirates

Background. Despite the cost effectiveness of physician smoking cessation counseling, many physicians do not adhere to current clinical practice guidelines. Methods. A cross-sectional mail survey was conducted in a sample of general practitioners in the United Arab Emirates (UAE), emirates of Sharjah, Dubai and Abu Dhabi, to document cessation-counseling practices and identify correlates of these activities. Results. Of 391 eligible GPs, 218 (56%) completed the questionnaire. Despite favorable beliefs/attitudes about cessation counseling, less than half of GPs (47%) indicated that they have the skills to help their patients quit smoking and only 24% knew of community resources to refer patients to. GPs who perceived physician barriers in offering smoking counseling as very important were significantly less likely to ascertain smoking status of most of their patients (OR: 0.28, 95% CI: 0.09,0.88). Moreover, high self-efficacy and favorable beliefs/attitudes were significantly associated with high level of counseling completeness (OR: 4.44, 95% CI: 1.21, 16.37; OR: 3.78, 95% CI: 1.25, 11.35; respectively). Conclusion. Support, training and intervention programs to overcome lack of awareness and knowledge, unfavorable beliefs/attitudes, and low self-efficacy could increase and enhance cessation-counseling practices among general practitioners in the UAE.

Self-reported smoking cessation activities among Swiss primary care physicians

Background

Individual counselling, pharmacotherapy, and group therapy are evidence-based interventions that help patients stop smoking. Acupuncture, hypnosis, and relaxation have no demonstrated efficacy on smoking cessation, whereas self-help material may only have a small benefit. The purpose of this study is to assess physicians' current clinical practice regarding smokers motivated to stop smoking.

Methods

The survey included 3385 Swiss primary care physicians. Self-reported use of nine smoking cessation interventions was scored. One point was given for each positive answer about practicing interventions with demonstrated efficacy, i.e. nicotine replacement therapy, bupropion, counselling, group therapy, and smoking cessation specialist. No points were given for the recommendation of acupuncture, hypnosis, relaxation, and self-help material. Multivariable logistic analysis was performed to identify factors associated with a good practice score, defined as ≥ 2.

Results

The response rate was 55%. Respondents were predominately over the age of 40 years (88%), male (79%), and resided in urban areas (74%). Seventeen percent reported being smokers. Most of the physicians prescribed nicotine replacement therapy (84%), bupropion (65%), or provided counselling (70%). A minority of physicians recommended acupuncture (26%), hypnosis (8%), relaxation (7%), or self-help material (24%). A good practice score was obtained by 85% of respondents. Having attended a smoking cessation-training program was the only significant predictor of a good practice score (odds ratio: 6.24, 95% CI 1.95–20.04).

Conclusion

The majority of respondents practice recommended smoking cessation interventions. However, there is room for improvement and implementing an evidence-based smoking cessation-training program could provide additional benefit.

Knowledge and management of smoking-cessation strategies among cardiologists in France: a nationwide survey

BACKGROUND

While cardiologists are very active in the prevention of cardiovascular disease, their attitudes towards patients' smoking habits are poorly studied.

AIMS

In a nationwide French survey, we assessed cardiologists' levels of knowledge and management of smoking cessation.

METHODS

We sent out a questionnaire to a random sample of 1000 cardiologists.

RESULTS

A total of 371cardiologists agreed to participate in the survey; 8.1% were current smokers and 32.4% were past smokers. Most classified smoking cessation as the top priority for patients with coronary artery disease (56.5%) and peripheral arterial disease (88.5%). Cardiologists routinely assessed active and passive smoking in 96.2% and 43% of their patients, respectively. Only 29.2% considered themselves well informed about smoking-cessation management. While 39.9% declared they knew about the minimal counselling 7.3% described it correctly. Only 17.5% used the Fagerström questionnaire. Smoking cessation was advised systematically by 85% but only 5.4% of cardiologists followed up their patients specifically on this issue. They referred smokers to either their general practitioner or to smoking-cessation centres and/or quitlines in 16.0% and 67.0% of cases, respectively; 31.8% never referred their patients to a smoking-cessation centre, and 25% declared being unaware of any such centre in their area. Cardiologists who smoked were less likely to ask about patients' smoking status than non-smokers (90% vs 98.2%, p=0.039). Similarly, they were more passive in offering smoking-cessation counselling (23% vs 7%, p=0.011), and referred less frequently their patients to a smoking-cessation centre (37% vs 64%, p=0.028).

CONCLUSION

French cardiologists are rarely involved in the management of smoking cessation. Their own smoking status influences their attitudes towards the management of smoking cessation.

Cigarette smoking: an undertreated risk factor for cardiovascular disease

Smoking and other forms of tobacco use are major risk factors for cardiovascular disease. The effect of cigarette smoking on cardiovascular health is evident even at the lowest levels of exposure. Yet, the adverse effects of smoking are reversible, with cardiovascular risk decreasing substantially within the first 2 years of smoking cessation. Significantly, the mortality from coronary heart disease is reduced more through smoking cessation than by other secondary preventive therapies such as cholesterol lowering. Smoking cessation is a highly effective way to improve cardiovascular health in smokers and extremely cost-effective. However, smoking cessation therapies are not implemented maximally if they are implemented at all, perhaps because smoking is seen as a lifestyle choice or because smokers frequently relapse, as indicated by very low long-term quit rates. Too often, healthcare professionals, including lipidologists and cardiologists, do little to address their patients' smoking status, in spite of its impact on cardiovascular health. With the advent of new therapies to treat the nicotine addiction that results from smoking and other tobacco use, it is hoped that physicians will be more proactive in encouraging and implementing smoking cessation programs for their patients, with the goal of increasing long-term quit rates, and reducing the morbidity and mortality associated with cardiovascular disease.

Does the smoking status of general practitioners affect the efficacy of smoking cessation counselling?

OBJECTIVE

To examine the association between the smoking status of general practitioners (GPs) and abstinence rates among patients receiving GP-delivered brief advice for smoking cessation.

METHODS

A quasi-experimental multilevel study with follow-up assessments at 6, 12, 18, and 24 months after baseline was conducted using a random sample of 39 general practices in a defined area (participation rate=87.2%). Patients aged 18-70 were consecutively screened for smoking status (n=11,560) over the course of 3 weeks and were assigned to a control group (week 1), a computer expert system intervention (week 2), or a personal counselling intervention with the GP (week 3). For the current analysis, patients participating in study week 2 were excluded. A total of 1260 patients fulfilled the inclusion criteria and 80.2% took part: 609 patients in study week 1 and 402 patients from study week 3. GPs participated in a training session concerning smoking counselling, which was held between study weeks 2 and 3. Self-reported 4-week and 6-month prolonged abstinence measures at the 6-, 12-, 18-, and 24-month follow-ups were assessed.

RESULTS

The smoking status of the GP was neither significantly related to 4-week prolonged abstinence nor 6-month prolonged abstinence among patients in a main effects model. Further modelling revealed that the intervention group modified the effect of the non-smoking status of the GP on the likelihood to quit smoking. A significant interactive effect was found between the non-smoking status of the GP and the intervention group on both abstinence measures.

CONCLUSION

The non-smoking status of the GP had a positive effect among counselled patients.

PRACTICE IMPLICATIONS

The consideration of lifestyle behavioural variables such as the smoking status of the GP will be essential for further research concerning the efficacy of smoking interventions.

Smoking cessation treatment by Dutch respiratory nurses: reported practice, attitudes and perceived effectiveness

OBJECTIVE

To describe Dutch respiratory nurses' current smoking cessation practices, attitudes and beliefs, and to compare these with a survey from the year 2000, before the national introduction of a protocol for the treatment of nicotine and tobacco addiction (the L-MIS protocol).

METHODS

Questionnaire survey among all 413 registered respiratory nurses in the Netherlands in 2006.

RESULTS

The response rate was 62%. Seventy-seven percent of the respondents reported to have "fairly good" or "good" knowledge of all steps of the L-MIS protocol. Seven out of 10 behavioural techniques for smoking cessation from the protocol were used by more than 94% of the respondents. Seventy-four percent of the respiratory nurses recommended the use of either nicotine replacement therapy (70%) or bupropion (44%). Almost two-thirds (65% of 254) perceived lack of patient's motivation as the most important barrier for smoking cessation treatment; a four-fold increase compared to the year 2000.

CONCLUSION

We conclude that respiratory nurses are compliant with the L-MIS protocol. They offer intensive support and use behavioural techniques for smoking cessation more frequently than evidence-based pharmacological aids for smoking cessation. Perceived lack of patient's motivation forms the most important threat to respiratory nurses' future smoking cessation activities.

PRACTICE IMPLICATIONS

International guidelines acknowledge that respiratory patients have a more urgent need to stop smoking but have more difficulty doing so. They should be offered the most intensive smoking cessation counselling in combination with pharmacotherapy. This kind of counselling may be more feasible for respiratory nurses than for physicians who often lack time. Their efforts could be increased by reimbursing pharmacological aids for smoking cessation and by developing simple tools to systematically assess motivation to quit and psychiatric co-morbidity in smoking patients.
