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

Oral health practitioners' knowledge, perceptions, and practices relating to e-cigarettes

OBJECTIVES

Despite the oral health risks associated with e-cigarette use (i.e., vaping) and the importance of cessation, research exploring the experiences and views of oral health practitioners in relation to e-cigarettes and delivering cessation counselling is limited. This study investigated oral health practitioners' (i) experiences with the oral health effects of e-cigarette use, (ii) knowledge and perceptions of e-cigarettes, and (iii) confidence in providing cessation advice to patients. We also explored desired support and preferences for training and education related to e-cigarettes.

METHODS

A cross-sectional online survey was completed by 192 oral health practitioners (e.g., dentists, oral health therapists) working in Australia. The survey measured experiences with patient e-cigarette use, perceptions of e-cigarettes, confidence providing patients with cessation advice, and needs and preferences for practitioner training.

RESULTS

There was near universal concern (n = 184, 96 %) regarding the effects of e-cigarette use on oral health. Two-thirds of respondents (n = 122, 65 %) rated their level of knowledge about e-cigarette use and detecting oral health damage from e-cigarette use as low. Only 29 % (n = 56) of respondents believed they had sufficient knowledge to provide advice and support to patients who use e-cigarettes. Interest in education related to e-cigarettes was high, with 98 % (n = 188) of respondents expressing an interest in completing an education module designed specifically for oral health practitioners.

CONCLUSIONS

A clear opportunity to improve vaping-related knowledge among oral health practitioners was identified. Providing oral health practitioners with evidence-based education about e-cigarettes and training in the delivery of appropriate cessation support is critical to increasing practitioner knowledge and confidence.

CLINICAL SIGNIFICANCE STATEMENT

Despite the oral health risks associated with e-cigarette use and the importance of cessation, few oral health practitioners report feeling well-supported in their efforts to manage e-cigarette use in their patients. The development of vaping-related resources, clinical guidelines, or training activities for oral health practitioners is urgently needed to facilitate evidence-based discussions with patients.

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.

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.

Enhanced Recovery After Surgery (ERAS) for Cranial Tumor Resection: A Review

Enhanced Recovery After Surgery (ERAS) protocols describe a standardized method of preoperative, perioperative, and postoperative care to enhance outcomes and minimize complication risks surrounding elective surgical intervention. A growing body of evidence is being generated as we learn to apply principles of ERAS standardization to neurosurgical patients. First applied in spinal surgery, ERAS protocols have been extended to cranial neuro-oncological procedures. This review synthesizes recent findings to generate evidence-based guidelines to manage neurosurgical oncology patients with standardized systems and assess ability of these systems to coordinate multidisciplinary, patient-centric care efforts. Furthermore, we highlight the potential utility of multimedia, app-based communication platforms to facilitate patient education, autonomy, and team communication within each of the three settings.

The Impact of Vaping on Primary Spontaneous Pneumothorax Outcomes

INTRODUCTION

Cigarette smoking is associated with primary spontaneous pneumothorax (PSP). Electronic cigarettes (E-cigarettes) are touted as a healthier alternative to cigarettes; however, the impact E-cigarette use has on PSP management is not known. The goal of this study was to determine if E-cigarette use is associated with inferior outcomes after PSP, compared to never smokers and cigarette smokers.

METHODS

We conducted a retrospective cohort study of patients in a large tertiary care hospital system in an urban area who presented with PSP from September 2015 through February 2019. Primary spontaneous pneumothorax patients were identified from the institutional Society of Thoracic Surgeon (STS) database. Patients with pneumothoraces from traumatic, iatrogenic, and secondary etiologies were excluded. Baseline clinical and demographic data and outcomes including intervention(s) required, length of stay, and recurrence were evaluated.

RESULTS

Identified were 71 patients with PSP. Seventeen (24%) had unverifiable smoking history. Of the remaining, 7 (13%) currently vaped, 27(50%) currently smoked cigarettes, and 20(37%) were never smokers. Mean age was 33 years; 80% male. All vapers required tube thoracostomy vs 74% of current smokers and 75% of never smokers. Vaping was associated with increased odds of recurrence compared to never smokers (OR 2.00, 95% CI 0.35,11.44). Vapers had the shortest median time to recurrence after initial hospitalization (10 d[4,18] v 20 d[5,13] cigarette smokers v 27 d[13 275] never smokers, P < .001).

CONCLUSION

Vaping may complicate PSP outcomes. As vaping use increases, especially among adolescents, it is imperative that the manner of tobacco use is documented and considered when caring for patients, especially those with pulmonary problems.

Are electronic cigarettes and vaping effective tools for smoking cessation? Limited evidence on surgical outcomes: a narrative review

The rising popularity of e-cigarettes and vaping, particularly in youth populations, has prompted the scientific community to ocassionally recommend their use as alternative to smoking or as a modality for smoking cessation. Media also tends to portray them as stylish, smoking cessation tools. We first studied the current literature to better understand whether they are viable options for surgeons to use prior to surgery as part of their armamentarium and their efficacy in attaining smoking abstinence. Next, we performed a comprehensive review of the literature to study the impact of e-cigarette and vaping on lung pathophysiology, surgical outcomes, and postoperative complications. After a thorough search, we found limited evidence suggesting that e-cigarettes and vaping are effective smoking cessation tools, and indeed may increase the propensity of dual smoking, contrary to e-cigarette advertisements. Many potential biases and limitations exist due to self-reporting when investigating e-cigarettes and vaping. While there is controversial data in the literature about e-cigarettes and vaping not leading to lung cancer, there are chemicals in these products that compromise lung hemostasis, negatively affect the immune system, and have detrimental inflammatory effects on wound healing. Studies are warranted to elucidate objective data regarding short and long-term effects of these products on surgical outcomes, and given the current data, they should not be utilized as viable smoking cessation tools.

Electronic cigarettes as a smoking cessation aid for patients with cancer: beliefs and behaviours of clinicians in the UK

OBJECTIVES

To explore UK clinicians' beliefs and behaviours around recommending e-cigarettes as a smoking cessation aid for patients with cancer.

DESIGN

Cross-sectional online survey.

SETTING

England, Wales, Scotland and Northern Ireland.

PARTICIPANTS

Clinicians involved in the care of patients with cancer.

PRIMARY AND SECONDARY OUTCOMES

Behavioural Change Wheel capability, opportunity and motivation to perform a behaviour, knowledge, beliefs, current practice around e-cigarettes and other smoking cessation practices.

METHOD

Clinicians (n=506) completed an online survey to assess beliefs and behaviours around e-cigarettes and other smoking cessation practices for patients with cancer. Behavioural factors associated with recommending e-cigarettes in practice were assessed.

RESULTS

29% of clinicians would not recommend e-cigarettes to patients with cancer who continue to smoke. Factors associated with recommendation include smoking cessation knowledge (OR 1.56, 95% CI 1.01 to 2.44) and e-cigarette knowledge (OR 1.64, 95% CI 1.06 to 2.55), engagement with patients regarding smoking cessation (OR 2.12, 95% CI 1.12 to 4.03), belief in the effectiveness of e-cigarettes (OR 2.36 95% CI 1.61 to 3.47) and belief in sufficient evidence on e-cigarettes (OR 2.08 95% CI 1.10 to 4.00) and how comfortable they felt discussing e-cigarettes with patients (OR 1.57 95% CI 1.04 to 2.36).

CONCLUSION

Many clinicians providing cancer care to patients who smoke do not recommend e-cigarettes as a smoking cessation aid and were unaware of national guidance supporting recommendation of e-cigarettes as a smoking cessation aid.

Validation of a nicotine vapor self-administration model in rats with relevance to electronic cigarette use

The debate about electronic cigarettes is dividing healthcare professionals, policymakers, manufacturers, and communities. A key limitation in our understanding of the cause and consequences of vaping is the lack of animal models of nicotine vapor self-administration. Here, we developed a novel model of voluntary electronic cigarette use in rats using operant behavior. We found that rats voluntarily exposed themselves to nicotine vapor to the point of reaching blood nicotine levels that are similar to humans. The level of responding on the active (nicotine) lever was similar to the inactive (air) lever and lower than the active lever that was associated with vehicle (polypropylene glycol/glycerol) vapor, suggesting low positive reinforcing effects and low nicotine vapor discrimination. Lever pressing behavior with nicotine vapor was pharmacologically prevented by the α4β2 nicotinic acetylcholine receptor partial agonist and α7 receptor full agonist varenicline in rats that self-administered nicotine but not vehicle vapor. Moreover, 3 weeks of daily (1 h) nicotine vapor self-administration produced addiction-like behaviors, including somatic signs of withdrawal, allodynia, anxiety-like behavior, and relapse-like behavior after 3 weeks of abstinence. Finally, 3 weeks of daily (1 h) nicotine vapor self-administration produced cardiopulmonary abnormalities and changes in α4, α3, and β2 nicotinic acetylcholine receptor subunit mRNA levels in the nucleus accumbens and medial prefrontal cortex. These findings validate a novel animal model of nicotine vapor self-administration in rodents with relevance to electronic cigarette use in humans and highlight the potential addictive properties and harmful effects of chronic nicotine vapor self-administration.

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.
