Lung cancer specialist physicians' attitudes towards e-cigarettes: A nationwide survey

Prevalence, knowledge, and concerns regarding the use of heated tobacco products and electronic cigarettes among young Japanese physicians

INTRODUCTION

Heated tobacco products (HTPs) and e-cigarettes (ECs) have gained traction as alternatives for harm reduction, especially in Japan. In particular, the use of HTPs is rapidly gaining popularity among young adults in Japan, with a prevalence of 10.9% in 2020. Despite uncertainties regarding the health effects of HTPs and ECs, concerns regarding nicotine and carcinogens persist. Although physicians play a vital role in smoking cessation, they lack awareness and concerns regarding HTPs. This study aimed to assess the prevalence, knowledge, and concerns regarding HTPs and ECs among young Japanese physicians.

METHODS

A cross-sectional online survey was conducted in 2021 with 529 young Japanese physicians aged 24-39 years. Parameters assessed included awareness, smoking status, knowledge of HTPs and ECs, and concerns related to HTPs. Statistical analyses were conducted to assess prevalence, knowledge, and concerns by smoking status using the chi-squared test and logistic regression.

RESULTS

Most participants were aware of HTPs (89.0%) and ECs (71.3%). Young male physicians preferred HTPs, while females favored ECs. Primary sources of information included newspapers and stories (56.8%), and TV (37.4%). Non-smokers (89.0%) demonstrated limited knowledge of these products. Concerns were highest and lowest among non-smokers and HTP users, respectively, with safety concerns being the most prevalent.

CONCLUSIONS

Young physicians exhibited lower smoking rates than the general population, but HTP use was prominent among young male physicians. Concerns varied based on smoking status, indicating the need to address these issues among healthcare professionals. Despite high awareness, knowledge gaps, particularly among non-smokers, highlight the importance of public health and educational campaigns to disseminate knowledge among physicians, regardless of medical specialty.

Knowledge and awareness of nicotine, nicotine replacement therapy, and electronic cigarettes among general practitioners with a special interest in respiratory medicine in China

Objectives

This study aimed to assess the knowledge and awareness of nicotine, nicotine replacement therapy (NRT), and electronic cigarettes (e-cigarettes) among general practitioners with a special interest (GPwSIs) in respiratory medicine.

Methods

A cross-sectional study was conducted from October 2021 to February 2022. Knowledge and awareness were compared among smokers and non-smokers, as well as different age and gender groups.

Results

The study consisted of 102 GPwSIs from 21 cities in Sichuan Province, China. Most respondents would recommend NRT for long-term use. Only a few believed that e-cigarettes are an effective means of smoking cessation and 71.6% would not recommend e-cigarettes as a substitute for cigarettes to their patients. Additionally, the majority did not regularly provide extensive help to assist patients in quitting smoking and needed smoking cessation counseling training.

Conclusion

GPwSIs in respiratory medicine in China could have a relatively low level of knowledge and awareness regarding nicotine, NRT, and e-cigarettes. The study highlights the need for smoking cessation training among GPwSIs to improve their knowledge and provide better assistance to patients who want to quit smoking.

General practitioners' knowledge, attitudes, beliefs and practices surrounding the prescription of e-cigarettes for smoking cessation: a mixed-methods systematic review

BACKGROUND

General practitioners (GPs) play an important role in providing patients who smoke with health information, support and treatment to encourage them to quit smoking. Despite conflicting evidence on the effectiveness of electronic cigarettes (e-cigarettes) as a smoking cessation aid, there is growing interest in the role e-cigarettes might play as an alternative to smoking tobacco. This systematic review aims to synthesise evidence from qualitative, quantitative and mixed-methods studies of the knowledge, attitudes, beliefs and social norms of GPs with respect to the use of e-cigarettes as smoking cessation aids.

METHODS

This study adhered to the PRISMA guidelines. Studies from MEDLINE, CINAHL, SCOPUS, PsycINFO, EMBASE and grey literature were searched. Two independent reviewers screened abstracts and full-text articles to identify studies that met the inclusion criteria. A data extraction form was used to extract relevant data from included papers and were quality appraised using the MMAT checklist. A PRISMA flow diagram was used to record the flow of papers and reasons for exclusion. Studies were included if they collected quantitative, qualitative or mixed methods data to determine knowledge, attitudes, beliefs and social norms of GPs for use of e-cigarettes as smoking cessation aids.

RESULTS

A total of 4056 abstracts were screened and 25 articles were included. Our findings showed that GPs had mixed views on recommending e-cigarettes as a smoking cessation aid. Some GPs were optimistic and had recommended e-cigarettes to their patients. Others were reluctant and disagreed that e-cigarettes are an effective method to quit smoking. Most GPs lacked knowledge and confidence in having discussions with patients around e-cigarette safety and efficacy as smoking cessation alternatives.

CONCLUSION

This systematic review shows there are mixed views on e-cigarettes as smoking cessation aids. Clear guidance on the role of e-cigarettes is needed to inform and upskill GPs about e-cigarettes for smoking cessation.

Beliefs and perceptions of electronic cigarettes among medical staff in respiratory departments of Fujian Province, China, in 2021

INTRODUCTION

Due to the popularity of e-cigarettes, more and more patients ask about e-cigarettes, and it is particularly important to understand doctors' beliefs and perceptions on e-cigarettes. The aim was to evaluate the belief and perception of electronic cigarettes among medical staff in the respiratory department of medical institutions located in Fujian Province.

METHODS

The electronic questionnaires were conveyed to the medical staff of the respiratory department in Fujian Province during March to April 2021. Descriptive statistics were calculated for all questions, and the relationship between relevant factors and the perception of e-cigarette-related statements was analyzed by logistic regression analysis.

RESULTS

Among 1028 medical staff in the respiratory departments of Fujian Province, 90.5% of medical staff agreed that electronic cigarettes are harmful to the human body; 61.4% of medical staff agreed that e-cigarettes cannot be regarded as a type of smoking cessation treatment; 71.7% of medical staff agreed that e-cigarettes could be a 'gateway' to other tobacco use; and 69.2% of medical staff agreed that electronic cigarettes are in 'Three No' states. The multivariate logistic regression analysis showed that the respondents' perception of 'e-cigarettes cannot be regarded as a type of smoking cessation treatment' were related to gender, professional title and whether they participated in the cessation clinic.

CONCLUSIONS

The medical staff of the respiratory department in Fujian Province put more emphasis on the adverse effects of e-cigarettes on health, but lack the cognition of the effect of e-cigarette smoking cessation. In order to better carry out smoking cessation work, it is necessary to strengthen the training of respiratory medical staff at all levels of medical institutions on e-cigarette knowledge.

Otolaryngology Resident Education and Perceptions of e-cigarettes

OBJECTIVE

To date, there are no reports of otolaryngology residents' knowledge and confidence in discussing e-cigarette use. The purpose of this study was to evaluate otolaryngology resident e-cigarette knowledge and confidence in counseling patients on e-cigarette use.

STUDY DESIGN

Cross-sectional national survey.

SETTING

Accreditation Council for Graduate Medical Education otolaryngology residents in the United States.

METHODS

US otolaryngology residents were distributed surveys electronically in September 2020.

RESULTS

A total of 150 participants replied for a response rate of 8.88%. The majority, 93.10% have not received formal education on e-cigarettes during their residency training. The most common resource of e-cigarette information overall was social media (78.46%). Within academia, the most common resources of e-cigarette education were patient interactions (63.16%) and colleagues (54.74%). Patients commonly inquire residents about e-cigarettes for smoking cessation (85.07%) and their long-term health effects (83.58%). Almost 67% of residents rarely or never ask patients about e-cigarette use. Only 4.35% of residents are not confident discussing traditional cigarette use, while 58.70% are not confident discussing e-cigarettes.

CONCLUSION

Otolaryngology residents have not received formal education in e-cigarettes and are not confident discussing e-cigarettes with their patients. This highlights the need for e-cigarette education during otolaryngology residency to improve patient e-cigarette counseling.

Knowledge and Attitudes Among Medical Students Toward the Clinical Usage of e-Cigarettes: A Cross-Sectional Study in a University Hospital in Saudi Arabia

Background

To assess knowledge and attitudes about e-smoking among undergraduate medical students, specifically focused on favorable view of therapeutic e-cigarette use for smoking cessation or harm reduction.

Methods

This cross-sectional study included medical students at King Abdulaziz University, Saudi Arabia. A six-item subscale was used to explore knowledge and attitudes about the therapeutic use of e-cigarettes, measuring participants' likelihood of favoring such use. A four-item questionnaire measured confidence and importance of being educated about smoking and e-smoking, in addition to sources of knowledge about e-cigarettes.

Results

A total of 399 students participated. Smoking history included current smokers (19.8%) and ex-smokers (6.5%), while e-cigarettes were tried by 36.6% and are currently used by 11.5%. A minority (13.5%) believed that e-cigarettes are FDA-approved for smoking cessation, while approximately one-third believed e-smoking lowers cancer risks (31.1%) and could help with smoking cessation (31.1%). Further, 35.9% agreed or strongly agreed that e-cigarettes are better for patients than tobacco products, and 17.5% were likely to recommend e-smoking to their patients for smoking cessation. Reliability of the six-item scale showed Cronbach's alpha = 0.676, which was enhanced to 0.746 after deletion of one item about addictiveness. Using the corrected five-item scale, 23.6% of the participants would favor therapeutic use of e-cigarettes.

Conclusion

We observed several misconceptions about addictiveness and inadequate awareness about e-cigarettes' harmful effects, leading to non-scientific opinions about its therapeutic use for harm reduction or in smoking cessation. Academic programs around this topic should be updated in accordance with majority expert recommendations.

Beliefs and Self-reported Practices of Health Care Professionals Regarding Electronic Nicotine Delivery Systems: A Mixed-Methods Systematic Review and Synthesis

AIMS

This review explores the (1) beliefs and attitudes of health care professionals (HCPs) toward electronic nicotine delivery systems (ENDS) including use as a smoking cessation aid and/or harm reduction, safety and regulation, and (2) the extent and content of patient-HCP communication about ENDS.

METHODS

PubMed, Embase, CINAHL, and PsycINFO were searched to identify articles published since 2003. The Mixed Methods Appraisal Tool and Strengthening the Reporting of Observational Studies in Epidemiology checklists were used to assess the quality of studies. Thematic synthesis was used to analyze qualitative data.

RESULTS

A total of 45 articles (32 quantitative, 12 qualitative, and 1 mixed) were included. There was wide variation regarding beliefs about the efficacy of ENDS as a cessation aid. Although the majority of HCPs believes that ENDS are safer than combustible cigarettes, they also have concern about the short and long-term safety of ENDS, uptake by adolescents, and the potential for ENDS to act as a "gateway" to smoking cigarettes. Beliefs about ENDS are influenced by media stories and experiences provided by patients. Although most HCPs do not proactively recommend ENDS, they are more likely to support ENDS use among patients with smoking related comorbidities, heavy smokers with previous unsuccessful quit attempts, or patients who express interest in trying them.

CONCLUSIONS

Overall, HCPs hold diverse views about the efficacy of ENDS and expressed wariness over their potential health effects. HCP endorsement of ENDS use seems to depend largely on patient health status, the presence of other competing risk factors and patient preferences.

IMPLICATION

Although evidence on safety and efficacy of ENDS is emerging, HCPs should be honest with their clients, stating that the long-term safety is not yet established but what is known is that they appear to be a lower risk alternative to cigarettes. Our review highlights a need for further training and support for HCPs regarding ENDS use, which would enable them to guide their clients in making evidence-based decisions.

Where there's smoke, there's fire: what current and future providers do and do not know about electronic cigarettes

Background

Health care providers play a pivotal role as educators on health-related matters ranging from vaccination to smoking cessation. With the rising popularity of electronic cigarettes (e-cigarettes), providers face a new challenge. To date, studies have identified a general lack of knowledge among providers regarding e-cigarettes and discomfort with counseling patients on e-cigarette use. This study aims to systematically explore the perspectives of different health care providers on e-cigarettes and their health implications. With a growing availability of research on the health consequences of e-cigarette use, our study also aims to assess the familiarity of our participants with this literature.

Methods

From July to October 2018, a sample of attendings (n = 15), residents (n = 15), medical students (n = 33), and nursing students (n = 28) from Thomas Jefferson University participated in a freelisting interview and survey.

Results

Our study found that perceptions of e-cigarettes vary across different participant groups, as evidenced by the range of responses when asked to think about e-cigarettes and their health implications. We identified gaps in knowledge among students regarding FDA regulation of e-cigarettes and found that attending physicians are less aware than junior trainees of the prevalence of use. Familiarity with evidence-based health consequences was variable and low across all groups. Finally, participants most commonly reported learning about e-cigarettes from news outlets and social media rather than professional platforms.

Conclusion

This study highlights the need for curricular development in nursing and medical schools, residency training, and continuing medical education regarding e-cigarette use and their impact on human health.

Beliefs and practices regarding electronic cigarettes in smoking cessation among healthcare professionals in Slovenia

INTRODUCTION

Electronic cigarettes (ECs) have generated extensive discussion about their role in smoking cessation. The Slovenia National Institute of Public Health's recommendations state that ECs are not to be recommended for smoking cessation or reduction. The aim of this study was to explore how healthcare professionals working in the field of preventive healthcare and smoking cessation in Slovenia communicate with and counsel patients regarding electronic cigarettes and smoking cessation or reduction.

METHODS

A cross-sectional, web-based survey was conducted among healthcare professionals working in the field of preventive healthcare and smoking cessation in Slovenia. A total of 479 healthcare professionals were included in the analysis.

RESULTS

While a minority of participants (12.7%) do or would recommend electronic cigarettes for smoking cessation or reduction in general, a higher proportion of participants (33.1%) would recommend electronic cigarettes to specific groups of patients. Knowledge on electronic cigarettes was the key determinant of differences in recommendations. Only a minority of participants (9.1%) reported availability of workplace guidelines/recommendations regarding counselling about electronic cigarettes.

CONCLUSIONS

Training programmes, educational materials and existing guidelines/recommendations regarding counselling about electronic cigarette use should be provided and distributed among healthcare professionals, together with efforts to ensure compliance to official guidelines/recommendations.

Discussions between health professionals and smokers about nicotine vaping products: results from the 2016 ITC Four Country Smoking and Vaping Survey

BACKGROUND AND AIMS

Debate exists about whether health professionals (HPs) should advise smokers to use nicotine vaping products (NVPs) to quit smoking. The objectives were to examine in four countries: (1) the prevalence of HP discussions and recommendations to use an NVP; (2) who initiated NVP discussions; (3) the type of HP advice received about NVPs; and (4) smoker's characteristics related to receiving advice about NVPs.

DESIGN

Cross-sectional study using multivariable logistic regression analyses on weighted data from the 2016 ITC Four Country Smoking and Vaping Survey (ITC 4CV1).

SETTING

Four countries with varying regulations governing the sale and marketing of NVPs: 'most restrictive' (Australia), 'restrictive' (Canada) or 'less restrictive' (England and United States).

PARTICIPANTS

A total of 6615 adult smokers who reported having visited an HP in the last year (drawn from the total sample of 12 294 4CV1 respondents, of whom 9398 reported smoking cigarettes daily or weekly). Respondents were from the United States (n = 1518), England (n = 2116), Australia (n = 1046), and Canada (n = 1935).

MEASUREMENTS

Participants' survey responses indicated if they were current daily or weekly smokers and had visited an HP in the past year. Among those participants, further questions asked participants to report (1) whether NVPs were discussed, (2) who raised the topic, (3) advice received on use of NVPs and (4) advice received on quitting smoking.

FINDINGS

Among the 6615 smokers who visited an HP in the last year, 6.8% reported discussing NVPs with an HP and 2.1% of smokers were encouraged to use an NVP (36.1% of those who had a discussion). Compared with Australia (4.3%), discussing NVPs with an HP was more likely in the United States [8.8%, odds ratio (OR) = 2.15, 95% confidence interval (CI) = 1.41-3.29] and Canada (7.8%, OR = 1.87, 95% CI = 1.26-2.78). Smokers in Australia were less likely to discuss NVPs than smokers in England (6.2%), although this was not statistically significant (OR = 1.47, 95% CI = 0.98-2.20). Overall, the prevalence of HPs recommending NVPs was three times more likely in the United States than in Australia (OR = 3.07, 95% CI = 1.45-6.47), and twice as likely in Canada (OR = 2.28, 95% CI = 1.06-4.87) than in Australia. Australia and England did not differ (OR = 1.76, 95% CI = 0.83-3.74). Just over half (54%) of respondents brought up NVPs themselves; there were no significant differences among countries.

CONCLUSIONS

Discussions in Australia, Canada, England, and the United States between smokers and health professionals about nicotine vaping products appear to be infrequent, regardless of the regulatory environment. A low percentage of health professionals recommended vaping products. This was particularly evident in Australia, which has the most restrictive regulatory environment of the four countries studied.

Beliefs, Attitudes, and Confidence to Deliver Electronic Cigarette Counseling among 1023 Chinese Physicians in 2018

Background: The use of electronic cigarettes (e-cigarettes) is gaining popularity, so it is important to evaluate physicians’ understanding of e-cigarettes. This study assessed the beliefs, attitudes, and confidence in e-cigarette counseling among Chinese physicians and explored the factors related to asking patients about e-cigarette use. Methods: Physicians from across China were invited to participate in a questionnaire survey using the platform provided by DXY (www.dxy.cn) in 2018. In total, 1023 physicians completed the online survey. Descriptive analyses were used to characterize the participants, and multivariate logistic regression analyses were applied to identify predictors of physicians’ asking about patients’ e-cigarette use. Results: Only 46.3% of respondents agreed that e-cigarettes had adverse health effects, and 66.8% indicated that e-cigarettes can be regarded as a type of smoking cessation treatment. We found that 61.3% thought it was important to discuss e-cigarettes with patients, and 71.7% reported feeling confident about their ability in counseling about e-cigarettes. Respondents who had used e-cigarettes (OR = 2.05; 95% CI: 1.16–2.63), had received training about e-cigarettes (OR = 3.13; 95% CI: 2.17–4.52), or were confident about their ability to answer patients’ question about e-cigarettes (OR = 2.45; 95% CI: 1.65–3.65) were more likely to ask patients about e-cigarette use. Physicians who showed a supportive attitude toward using e-cigarettes to quit smoking (OR = 0.79; 95% CI: 0.63–0.99) were less likely to ask about patients’ e-cigarettes use frequently. Conclusions: Chinese physicians appeared to ignore the adverse health effects of e-cigarettes, and considered e-cigarettes as a smoking cessation treatment. Comprehensive training and regulations are needed to help physicians incorporate the screening of e-cigarette use into routine practice and provide patients truthful information as new data emerge.

Knowledge and Beliefs of E-Cigarettes Among Physicians in Poland

BACKGROUND Electronic nicotine delivery systems, including electronic cigarettes (e-cigarettes) are gaining popularity. The objectives of this study were to assess the knowledge and beliefs about e-cigarettes among physicians in Poland. MATERIAL AND METHODS A questionnaire-based survey was conducted among physicians attending mandatory courses delivered at the School of Public Health, Centre of Postgraduate Medical Education (Warsaw, Poland). The questionnaire included 24 questions concerning beliefs and attitudes about e-cigarettes. RESULTS Data were obtained from 412 physicians (64.3% females; aged 31.9±5.7 years) with a response rate of 82.4%. Among participants, 99.8% were aware of e-cigarettes. The main sources of information about e-cigarettes were: news stories (67.2%) or points of sale of e-cigarettes (67.6%). Approximately half of respondents (50.2%) declared moderate knowledge about e-cigarettes, and over three-quarters (78.1%) declared willingness to learn more about e-cigarettes. The majority (96.5%) of participants agreed with the statement that e-cigarette use is harmful to the user's health, and most (80.5%) agreed that exhaled e-cigarette aerosol is harmful to bystanders. The statement that e-cigarettes could be "gateway" to conventional smoking was supported by 87% of participants. Only 11.5% of physicians agreed that e-cigarettes should be recommended as a smoking cessation method. CONCLUSIONS Physicians in Poland perceive e-cigarettes as harmful and addictive. Physicians' knowledge about e-cigarettes is mostly based on non-scientific sources, which points out the urgent need to develop national smoking cessation guidelines regulating the issue of e-cigarettes based on scientific evidence.

Electronic Cigarettes and Smoking Cessation in the Perioperative Period of Cardiothoracic Surgery: Views of Australian Clinicians

For patients who smoke, electronic cigarettes may offer a pathway to achieve tobacco abstinence and reduce the risk of postoperative complications. Clinicians have a pivotal role in supporting smoking cessation by patients with lung cancer and coronary artery disease throughout the perioperative period of cardiothoracic surgery. However, the views of Australian cardiothoracic clinicians on electronic cigarettes and smoking cessation are unknown. Semi-structured interviews were conducted with 52 cardiothoracic surgeons, anaesthetists, nurses and physiotherapists in six hospitals in Sydney and thematically analysed. Clinicians’ knowledge about electronic cigarettes and the regulatory environment surrounding them was limited. Clinicians believed that: electronic cigarettes, though unlikely to be safe, were safer than tobacco cigarettes; electronic cigarettes may have a harm reduction role in public health; and electronic cigarettes were a potential smoking cessation tool for the extraordinary circumstances of surgery. The professional role of a clinician and their views about electronic cigarettes as a perioperative smoking cessation aid had an influence on future clinician-patient interactions. Electronic cigarette use is increasing in Australia and clinicians are likely to receive more frequent questions about electronic cigarettes as a cessation aid. Stronger guidance for clinicians is needed on the topic of electronic cigarettes and cardiothoracic surgery.

Electronic cigarette use among patients with cancer: Reasons for use, beliefs, and patient-provider communication

OBJECTIVE

Smoking tobacco cigarettes after a cancer diagnosis increases risk for several serious adverse outcomes. Thus, patients can significantly benefit from quitting smoking. Electronic cigarettes are an increasingly popular cessation method. Providers routinely ask about combustible cigarette use, yet little is known about use and communication surrounding e-cigarettes among patients with cancer. This study aims to describe patterns, beliefs, and communication with oncology providers about e-cigarette use of patients with cancer.

METHODS

Patients with cancer (N = 121) who currently used e-cigarettes were surveyed in a cross-sectional study about their patterns and reasons for use, beliefs, and perceptions of risk for e-cigarettes, combustible cigarettes, and nicotine replacement therapies. Patient perspectives on provider communication regarding e-cigarettes were also assessed.

RESULTS

Most participants identified smoking cessation as the reason for initiating (81%) and continuing (60%) e-cigarette use. However, 51% of patients reported current dual use of combustible cigarettes and e-cigarettes, and most patients reported never having discussed their use of e-cigarettes with their oncology provider (72%). Patients characterized e-cigarettes as less addictive, less expensive, less stigmatizing, and less likely to impact cancer treatment than combustible cigarettes (Ps < .05), and more satisfying, more useful for quitting smoking, and more effective at reducing cancer-related stress than nicotine replacement therapies (Ps < .05).

CONCLUSIONS

Patients with cancer who use e-cigarettes have positive attitudes toward these devices and use them to aid in smoking cessation. This study also highlights the need for improved patient-provider communication on the safety and efficacy of e-cigarettes for smoking cessation.

A national survey of lung cancer specialists' views on low-dose CT screening for lung cancer in Korea

Lung cancer specialists play an important role in designing and implementing lung cancer screening. We aimed to describe their 1) attitudes toward low-dose lung computed tomography (LDCT) screening, 2) current practices and experiences of LDCT screening and 3) attitudes and opinions towards national lung cancer screening program (NLCSP). We conducted a national web-based survey of pulmonologists, thoracic surgeons, medical oncologists, and radiological oncologists who are members of Korean Association for Lung Cancer (N = 183). Almost all respondents agreed that LDCT screening increases early detection (100%), improves survival (95.1%), and gives a good smoking cessation counseling opportunity (88.6%). Most were concerned about its high false positive results (79.8%) and the subsequent negative effects. Less than half were concerned about radiation hazard (37.2%). Overall, most (89.1%) believed that the benefits outweigh the risks and harms. Most (79.2%) stated that they proactively recommend LDCT screening to those who are eligible for the current guidelines, but the screening propensity varied considerably. The majority (77.6%) agreed with the idea of NLCSP and its beneficial effect, but had concerns about the quality control of CT devices (74.9%), quality assurance of radiologic interpretation (63.3%), poor access to LDCT (56.3%), and difficulties in selecting eligible population using self-report history (66.7%). Most (79.2%) thought that program need to be funded by a specialized fund rather than by the National Health Insurance. The opinions on the level of copayment for screening varied. Our findings would be an important source for health policy decision when considering for NLCSP in Korea.

The knowledge, concerns and healthcare practices among physicians regarding electronic cigarettes

Background: Electronic cigarettes (e-cigarettes) are battery-powered devices that deliver aerosolized nicotine. With easy access and over-the-counter availability, many patients consider using electronic cigarettes for smoking cessation. Few studies have looked at long-term safety/efficacy and physician knowledge/attitudes toward e-cigarettes. Physicians have insufficient guidelines for advising their patients about e-cigarettes.

Objective: 1) To identify knowledge and attitude of health care practitioners toward electronic cigarettes. 2) To identify the effect of level of training, experience and speciality on knowledge and practice of electronic cigarettes. 3) To identify factors influencing electronic cigarettes advise/prescribing practice.

Methods: An anonymous online questionnaire was sent to residents, fellows, and faculty in pre-selected specialties at Saint Louis University (SLU) Hospital.

Results: We received 115 responses. Nine percent reported being ‘very familiar’ with e-cigarettes, while 25% reported no familiarity; 18% of physicians would advise e-cigarettes as nicotine-replacement therapy if asked by patients; 91% were aware of the nicotine content of e-cigarettes, but only 20% and 39%, respectively, were aware of the presence of carcinogens and polyethylene glycol. Only 63% of respondents knew what ‘vape’ meant. Lack of evidence regarding long-term safety (76%), e-cigarettes as starter products for nonsmokers (50%), absence of Food and Drug Administration (FDA) regulations (51%) and marketing to youth (42%) were major concerns. Stricter regulations (54%), warning labels similar to tobacco products (53%), restricting advertising (36%), banning sales to minors (34%), and banning use in public spaces (25%) were favored as regulatory measures. More than 50% of physicians see a role for e-cigarettes as part of ‘harm-reduction strategy’.

Conclusions: Further research is needed to assess whether e- cigarettes could be an effective smoking-cessation tool. There is an apparent knowledge deficit among physicians and an urgent need for evidence-based guidelines to aid with advising patients enquiring about e-cigarettes.
