[PMID: 36878414 PMCID: PMC10475485 DOI: 10.1016/j.amepre.2023.02.030] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 02/24/2023] [Accepted: 02/27/2023] [Indexed: 03/06/2023]
Abstract
INTRODUCTION Primary care visits present an opportune time to assess behaviors that contribute to patient health. Smoking, alcohol use, and illicit drugs are routinely documented in electronic health records, but less is known about screening for E-cigarette use and the prevalence of E-cigarette use in primary care settings. METHODS Data include 134,931 adult patients who visited 1 of 41 primary care clinics within a 12-month period (June 1, 2021-June 1, 2022). Data on demographics, combustible tobacco, alcohol, illicit drug, and E-cigarette use were extracted from electronic medical records. Logistic regression was utilized to examine the variables associated with differential odds of being screened for E-cigarette use. RESULTS Rates of E-cigarette screening (n=46,997; 34.8%) were significantly lower than that of tobacco (n=134,196; 99.5%), alcohol (n=129,766; 96.2%), and illicit drug (n=129,766; 92.6%) use. Of those assessed for E-cigarette use, 3.6% (n=1,669) reported current use. Of those with documented nicotine use (n=7,032), 17.2% (n=1,207) used mono E-cigarettes exclusively, 76.3% (n=5,364) used combustible tobacco exclusively, and 6.6% (n=461) reported dual use (both E-cigarette use and combustible tobacco use). Those who used combustible tobacco or illicit substances as well as younger patients were more likely to have been screened for E-cigarette use. CONCLUSIONS Overall rates of E-cigarette screening were significantly lower than those of other substances. The use of combustible tobacco or illicit substances was associated with an increased likelihood of being screened. This finding may be because of the relatively recent proliferation of E-cigarettes, the recent addition of E-cigarette documentation to the electronic health record, or a lack of training on screening for E-cigarette use.

Feasibility of a primary care patient decision aid for smoking cessation with information about e-cigarettes. Prev Med Rep 2022; 26:101745. [PMID: 35251914 PMCID: PMC8892147 DOI: 10.1016/j.pmedr.2022.101745] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2021] [Revised: 01/28/2022] [Accepted: 02/26/2022] [Indexed: 11/17/2022] Open
Abstract
Decision aids can promote shared decision making and behavior change and may be effective in helping patients quit smoking. Patients are increasingly using e-cigarettes for smoking cessation; however, little is known about the impact of including e-cigarette information in smoking cessation decision aids. Our objective was to assess the feasibility and acceptability of a smoking cessation decision aid including e-cigarette information. This study was conducted at one family medicine clinic in the United States. We used a pre-post design. In Phase I, the decision aid presented information about approved cessation methods. In Phase II, current e-cigarette users and patients with no intention of quitting received additional information on switching to e-cigarettes. We assessed the impact of the decision aids on quit attempts and abstinence, confidence and readiness to quit, confidence and readiness to switch to e-cigarettes, and patient satisfaction. We enrolled 60 patients in each phase (N = 120). Patients reported higher confidence and readiness to quit after viewing the decision aids and consulting with their physician (p < 0.01). Patients reported the decision aid helped prepare them to make a decision about quitting smoking and expressed satisfaction with the decision aid and clinician consultation. We did not observe an impact of including e-cigarette information. Smoking cessation decision aids are acceptable to patients and may promote behavior change. Future studies should explore the impact of providing patients e-cigarette information using larger sample sizes and rigorous designs. Further research is needed to identify strategies to promote shared decision-making regarding e-cigarettes.

Primary Care Physician Perspectives on Recommending E-cigarettes to Smokers: a Best-Worst Discrete Choice Experiment. J Gen Intern Med 2021; 36:3353-3360. [PMID: 33523343 PMCID: PMC8606483 DOI: 10.1007/s11606-021-06615-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/04/2020] [Accepted: 01/07/2021] [Indexed: 10/22/2022]
Abstract
BACKGROUND Recent clinical trials suggest that e-cigarettes may be more effective for smoking cessation than traditional cessation aids, yet primary care physician (PCP) practices regarding e-cigarette recommendations for smokers have not been studied in-depth. OBJECTIVE To identify factors influencing PCP recommendation of e-cigarettes for smoking cessation. DESIGN Discrete choice experiment and survey. PARTICIPANTS Florida PCPs. MEASURES The survey included a discrete choice experiment in which PCPs indicated whether they would recommend e-cigarettes for each of 8 hypothetical patient profiles with the following contrasting characteristics: e-cigarette use, interest in approved cessation methods, smoking intensity, prior experience with approved cessation medications, quit intention, age, and comorbidity. Responses were summarized using descriptive statistics and standardized scores (SS). KEY RESULTS The sample (n = 216) was predominately male (76%), white (66%), and non-Hispanic (78%), and most respondents had held their medical degree for 20+ years (77%). The response rate was 28.7%. Most PCPs thought e-cigarettes were at least somewhat effective for smoking cessation (66%) and lowering disease risk (65%); 31% perceived e-cigarettes to be equally/more effective than traditional cessation aids. PCPs were split regarding whether e-cigarettes were less (50%) or equally harmful (38%) as cigarettes. Yet, few were very confident in their ability to counsel patients on e-cigarettes risks (27%) or benefits (15%). PCPs recommended e-cigarettes in 27% of patient profiles they evaluated. The most important factors influencing the decision to recommend or not recommend e-cigarette were patients' prior use of nicotine replacement therapy with (SS = 0.22, 95% CI = 0.17-0.27) and without use of other medications for cessation (SS = 0.18, 95% CI = 0.13-0.23), and being middle age (50 years old) with chronic obstructive pulmonary disease (SS = 0.16, 95% CI = 0.10-0.23). CONCLUSIONS Considering the increased patient use of e-cigarettes and increasing use for cessation, this study highlights the need for guidelines and education to aid PCPs' counseling of patients about e-cigarette use.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph182010861. [PMID: 34682603 PMCID: PMC8535370 DOI: 10.3390/ijerph182010861] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/02/2021] [Revised: 10/05/2021] [Accepted: 10/09/2021] [Indexed: 11/16/2022]
Abstract
Vaporizers (e-cigarettes) are the most common smoking cessation aids in Switzerland, but we do not know what information customers receive in vape shops. We surveyed vape-shop managers to find out what recommendations they make to their customers. An interdisciplinary group developed the questionnaire. Respondents self-reported their smoking history, demographics, and the recommendations they thought they would give to hypothetical customers in clinical vignettes. We also queried if they collaborated with health care professionals. Of those contacted, 53.8% (70/130) of vape-shop managers responded, and 52.3% (68/130) were included in the final analysis. Managers were mostly male and ex-smokers who switched to vaporizers; 60.3% would encourage a hypothetical smoker with high nicotine dependence to start with the highest possible nicotine concentration when switching to vaporizers. For this smoker, 36.9% would recommend high (≥15 mg/mL), 32.3% medium (6–14 mg/mL), and 3.1% low (1–5 mg/mL) nicotine concentrations. The rest adapted their recommendations to fit the customer or device; 76.5% reported that physicians referred customers to them, and 78.8% would attend a course given by experts in the field of vaporizers and smoking cessation. Vape-shop managers varied widely in the recommendations they gave customers. Most reported ongoing collaboration with health care professionals and were interested in improving their counselling skills through training.

Health Professionals' Counseling about Electronic Cigarettes for Smokers and Vapers in a Country That Bans the Sales and Marketing of Electronic Cigarettes. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17020442. [PMID: 31936477 PMCID: PMC7013470 DOI: 10.3390/ijerph17020442] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 11/29/2019] [Revised: 12/20/2019] [Accepted: 01/08/2020] [Indexed: 12/18/2022]
Abstract
This study describes the prevalence and correlates of adult smokers’ discussions about electronic cigarettes (e-cigarettes) with health professionals (HPs), including whether these discussions may lead smokers and vapers to use e-cigarettes for smoking cessation. Methods: We analyzed data from an online survey of Mexican smokers recruited from a consumer panel for marketing research. Participants who had visited an HP in the prior four months (n = 1073) were asked about discussions of e-cigarettes during that visit and whether this led them to try to quit. Logistic models regressed these variables on socio-demographics and tobacco use-related variables. Results: Smokers who also used e-cigarettes (i.e., dual users) were more likely than exclusive smokers to have discussed e-cigarettes with their HP (adjusted odds ratio (AOR) = 3.96; 95% C.I. 2.73, 5.74), as were those who had recently attempted to quit smoking (AOR = 1.89; 95% C.I. 1.33, 2.7). Of smokers who had discussed e-cigarettes, 53.3% reported that the discussion led them to use e-cigarettes in their quit attempt. Also, dual users (AOR = 2.6; 95% C.I. 1.5, 4.5) and daily smokers (>5 cigarettes per day) (AOR = 3.62; 95% C.I. 1.9, 6.8) were more likely to report being led by their HP to use e-cigarettes in the quit attempt compared to exclusive smokers and non-daily smokers, respectively. Conclusions: Discussions between HP and smokers about e-cigarettes were relatively common in Mexico, where e-cigarettes are banned. These discussions appear driven by the use of e-cigarettes, as well as by greater smoking frequency and intentions to quit smoking.

Abstract
BACKGROUND Primary care settings provide opportunities to identify electronic-cigarette (e-cigarette) use and to implement strategies for changing tobacco use behavior. However, a better understanding of the extent and associated characteristics of e-cigarette use among primary care patients are needed to inform such efforts. OBJECTIVE To describe patient demographic and substance use characteristics by e-cigarette use status among a large sample of primary care patients. To examine the prevalence and correlates of e-cigarette use among tobacco users in the sample. DESIGN Cross-sectional analysis from a multisite validation study of a substance use screening instrument. PARTICIPANTS Adult primary care patients aged 18 and older (n = 2000) recruited across 5 primary care clinics in the Eastern USA from 2014 to 2015. MAIN MEASURES Patients reported past 3-month e-cigarette use, sociodemographics, tobacco use, and other substance use. Current nicotine dependence and DSM-5 criteria for past-year substance use disorders were also assessed. KEY RESULTS Among the total sample, 7.7% (n = 154) adults reported past 3-month e-cigarette use. Adults who reported e-cigarette use (vs. no use) were more likely to be younger, white, or have frequent tobacco use, nicotine dependence, or past-year illicit drug use/disorders. Among past 3-month tobacco users, 16.3% reported e-cigarette use. Adjusted logistic regression indicated that odds of e-cigarette use were greater among tobacco users who had some college education or more (vs. < high school) or were daily/almost daily tobacco users (vs. not); odds were lower among Blacks/African-Americans (vs. whites). E-cigarette use among tobacco users was associated with increased odds of current nicotine dependence or tobacco use disorder as well as more severe dependence/disorder. CONCLUSIONS Enhanced surveillance of e-cigarette use among adult tobacco users in primary care, particularly among those who use tobacco frequently, may have implications for helping patients with tobacco cessation using established approaches including behavioral support, pharmacotherapy, or referral to specialized care.

Abstract
RATIONALE, AIMS, AND OBJECTIVES There is limited research on how health care providers approach the topic of e-cigarettes in clinical encounters, especially in conjunction with other best-practice recommendations for smoking cessation. This qualitative study explored physician perceptions and recommendations involving e-cigarettes in the context of smoking cessation counselling, including their opinions about the implementation and content of patient educational materials that focus on e-cigarettes. METHODS Semistructured interviews were conducted with 15 physicians from family medicine, internal medicine, and obstetrics/gynaecology (OB/GYN). RESULTS Physicians did not routinely assess e-cigarette use among patients and reported that discussions were often initiated by patients. Only a minority of participants discussed e-cigarettes in conjunction with other best-practice recommendations for smoking cessation. Most others were more ambivalent about e-cigarette safety and effectiveness for cessation and did not address the topic, unless patients were already using e-cigarettes. Almost all, however, agreed that more research on e-cigarettes was needed. Physicians expressed an interest in having enhanced discussions about e-cigarettes with their patients and in using patient educational materials to accomplish this. Physicians recommended that these materials not actively promote e-cigarettes and be tailored to patients based on their demographics and motivation to quit. CONCLUSIONS Physicians were open to improving their smoking cessation counselling and to integrating new patient educational materials that addressed e-cigarettes. Patient educational materials that provide tailored information about e-cigarettes could potentially be used initiate e-cigarette discussions and inform smokers about what is known vs unknown about e-cigarettes.

Abstract
Objective We assessed associations between electronic cigarette (e-cigarette) use and smoking-related measures among American Indians (AIs) who smoke. MethodsWe collected baseline survey and smoking biomarker data in a cohort of 375 adult AI smokers at a Cherokee Nation healthcare facility in Oklahoma. We used multivariate logistic and linear regression analyses to determine associations between e-cigarette use and smoking-related characteristics, including biomarkers. ResultsCurrent e-cigarette users were more likely than never users to report a quit attempt in the past 12 months (current vs never adjusted odds ratio (AOR) = 2.24 [95% CI 1.20-4.16]). Current and past e-cigarette users were more likely than never users to report a likelihood to quit smoking (current vs never AOR = 2.97 [95% CI 1.34-6.56]; past vs never AOR = 1.77 [95% CI 1.08-2.91]). E-cigarette use was not significantly associated with confidence to quit smoking, cigarette packs smoked per day, or cotinine levels. ConclusionsE-cigarette use was associated with previous and future quit attempts, but not with reductions in cigarette smoking or confidence in quitting. This suggests that many dual users might benefit from the addition of evidence-based smoking cessation treatments.
