Quitline nurses' experiences in providing telephone-based smoking cessation help to mental health patients: A mixed methods study.

WHAT IS KNOWN ON THE SUBJECT?: Quitlines are known to be effective in helping people quit smoking, including those with mental health conditions. It is particularly important to address smoking in this population as the prevalence of smoking ranges from 40% to 75%. However, professionals working in quitlines often face barriers due to their limited training and resources to effectively support these smokers quit, especially if they are not mental health professionals. Therefore, training programmes should be developed to enhance their knowledge and skills in providing smoking cessation support to this vulnerable population. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: The '061 QUIT-MENTAL study' evaluated the efficacy of a proactive telephone-based intervention for smoking cessation among smokers with severe mental health disorders. Conducted through a quitline service in Catalonia, Spain, the study focused on training non-mental health specialized nurses and other health professionals to provide evidence-based interventions for promoting smoking cessation among individuals with mental health disorders. The objective of this study is to assess the changes in nurses' knowledge and readiness to treat smokers with mental health conditions, while also capturing their insights and perceptions regarding the facilitators and barriers to providing smoking cessation interventions. The training and insights of the nurses were integral to conducting this research and providing valuable information for the future sustainability of such interventions. This is particularly important as quitlines hold the potential to offer cessation support to these patients at the community level. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: While the training programme was successful in improving non-mental health specialized nurses' knowledge and motivation skills to help patients with mental health disorders quit smoking, they encountered obstacles in delivering this intervention over the phone. These difficulties were mainly due to challenges in reaching participants and delivering the intervention as detailed in the protocol. The study highlights the need of reducing barriers for providers in attending to these patients, particularly if they are non-mental health specialized professionals. By minimizing the stigmatization associated with caring for mentally ill individuals and promoting coordination with specialists, innovative approaches may be introduced to alleviate the burden of tobacco-related diseases among this population. ABSTRACT: Introduction The viewpoint of those who implement a programme for the first time is crucial for understanding its impact and ensuring its long-term viability. The 061 QUIT-MENTAL study was a pragmatic randomized controlled trial evaluating a proactive telephone-based intervention addressed to mental health patients conducted by non-psychiatric specialized nurses. Aim We assessed nurses' knowledge of smoking cessation interventions addressed to this population before and after receiving training and their insights after delivering the intervention. Method Mixed methods study: (1) Pre-post evaluation to assess self-reported knowledge, self-efficacy and opinions about smoking cessation. (2) In-depth interviews with key nurses to ascertain their perceptions regarding the impact of the training received in delivering the study intervention. Results The training enhanced nurses' knowledge of psychological and pharmacological resources to aid these patients, as well as their ability to increase their motivation to quit. However, nurses reported difficulties in delivering population-based interventions to individuals with mental health disorders. These challenges primarily arose from participants being hard to reach, exhibiting low motivation to quit, struggling to comprehend instructions or follow recommendations, and nurses feeling unsure about their capacity to assist individuals with mental illnesses in quitting, despite the training they received. Discussion Despite the training and protocol designed to facilitate the delivery of the intervention, nurses faced difficulties in providing population-based interventions to individuals with mental health disorders. Implications for Practice Future quitline programmes aimed at the population with mental health disorders should strive to reduce barriers for providers in attending to these patients, particularly if they are non-mental health specialized professionals. By minimizing the stigmatization associated with caring for mentally ill individuals and promoting coordination with specialists, innovative approaches may be introduced to alleviate the burden of tobacco-related diseases among this population.

Training mental health residents in tobacco and alcohol: Relationship with their clinical intervention. / Formación en tabaco y alcohol de residentes de salud mental: Relación con su intervención clínica.

The objective of this study is to describe how mental health professionals in training (residents) apply the brief intervention (5As) on the tobacco and alcohol consumption to their patients, and if this is related to the training received and/or their own consumption. This is a cross-sectional study in which a self-reported questionnaire was administered to first-year residents of mental health professionals in Catalonia (2016-2019) (psychiatrists, psychologists and nurses). We performed a descriptive analysis of the variables and we applied a chi-square test for the comparison of proportions. 154 professionals completed the questionnaire. Half of them had not received any university training on intervention in smoking (46.8%) or in alcohol consumption (53.2%). Those who had received it, advised, assessed and helped their patients to quit smoking more frequently (p = 0.008, p = 0.037 and p = 0.039, respectively). Those who had received training in alcohol intervention gave advice, performed assessments and offered help to quit/reduce alcohol among their patients more frequently (p < 0.001, p = 0.001, and p < 0.001, respectively). Residents usually helped more to quit or reduce alcohol than to quit tobacco (p < 0.001). 60.1% of them never or rarely helped their patients to stop smoking and 34.6% rarely helped in the case of alcohol. In general, nurses did more intervention for tobacco than alcohol use, regardless of the training received. The lack of training of professionals in tobacco and alcohol intervention at university is related to a lack of intervention on patients in their professional practice, regardless of their own consumption.

El objetivo del estudio es analizar la intervención breve 5As en tabaco y alcohol de los profesionales sanitarios residentes de salud mental y analizar su relación con la formación recibida y/o con su propio consumo. Se trata de un estudio transversal en el que se administró un cuestionario autoinformado a residentes de primer año de salud mental de Cataluña de 2016 a 2019 (médicos, psicólogos y enfermeras). Se realizó un análisis descriptivo de las variables y comparación de proporciones a través de pruebas chi-cuadrado. Contestaron 154 profesionales, la mitad no había recibido ninguna formación universitaria sobre intervención en tabaquismo (46,8%), ni en consumo de alcohol (53,2%). Los que sí la habían recibido, aconsejaban, evaluaban y ayudaban a dejar de fumar a sus pacientes con mayor frecuencia (p = 0,008, p = 0,037 y p = 0,039; respectivamente). Los que habían recibido formación en alcohol, aplicaban más consejo, evaluación y deshabituación sobre el alcohol a sus pacientes (p < 0,001; p = 0,001; y p < 0,001; respectivamente). En global, ayudaban más a dejar o reducir el alcohol que el tabaco (p < 0,001). Un 60,1% de todos ellos nunca o raramente ayudaba a sus pacientes a dejar de fumar y un 34,6% en el caso del alcohol. Las enfermeras intervenían más en tabaquismo que en alcohol, hubieran recibido o no formación universitaria. El estudio concluye que la poca formación universitaria recibida por los profesionales se asocia con una frecuencia baja de intervención sobre sus pacientes, sin que exista relación entre el nivel de intervención y su propio consumo.

Specific biomarker comparison in current smokers, e-cigarette users, and non-smokers.

INTRODUCTION: This study aims to address the existing gap in the literature, while adding evidence, by comparing tobacco-specific biomarkers (cotinine and nitrosamines: NNK, NNAL, NNN), and other biomarkers of e-cigarette use (humectants: glycerol, 1,2-PD, 1,3-PD) according to five study groups. METHODS: A pooling analysis including two different studies was conducted. In both analyses, we took saliva samples from smokers (n = 409) and non-smokers (n = 154), dual tobacco and e-cig users (n = 92), exclusive e-cig user with nicotine (n = 158), and exclusive e-cig users without nicotine (n = 38). We analyzed and compared the geometric means (GM) and geometric standard deviations (GSD) of the concentration of tobacco-specific biomarkers, and e-cigarette biomarkers among groups. We used log-linear models adjusted for sex and age to model the change percentage and their 95% confidence intervals. RESULTS: Cotinine was significantly higher in nicotine consumers and in e-cigarette users without nicotine when compared to non-smokers. TSNAs were generally significantly lower in non-smokers and higher in nicotine consumers. NNN and NNAL were lower in e-cigarette users with nicotine comparted to smokers, and NNN was higher in e-cigarette users without nicotine when compared to non-smokers. No differences were found in humectant biomarkers between e-cigarette groups. CONCLUSIONS: Although there was a reduction in TSNAs in e-cigarette exclusive users compared to smokers, and a reduction of cotinine concentrations in e-cigarette exclusive users without nicotine compared to smokers, there are still high levels of these biomarkers when compared to non-smokers, which may be a clue towards the harmful effect of e-cigarettes.

Variation in Nicotine Metabolization According to Biological Factors and Type of Nicotine Consumer.

This study aims to describe the nicotine metabolite ratio among tobacco smokers and electronic cigarette (e-cigarette) users and nonusers. We analyzed pooled data from a longitudinal and a cross-sectional study of the adult population from the city of Barcelona. The final sample included information on 166 smokers, 164 e-cigarettes users with nicotine, 41 e-cigarette users without nicotine, 95 dual users (users of both products), and 508 nonusers. We used log-linear models to control for the potential confounding effect of the daily number of cigarettes smoked. Salivary nicotine metabolic rate assessment included the rate of nicotine metabolism (cotinine/nicotine) and the nicotine metabolite ratio (trans-3'-hydroxycotinine/cotinine). Exclusive users of e-cigarette without nicotine have the lowest rate of nicotine metabolism (Geometric mean: 0.08, p-values < 0.001) while cigarette smokers have the highest (Geometric mean: 2.08, p-values < 0.001). Nonusers have lower nicotine metabolic rate than cigarette smokers (Geometric means: 0.23 vs. 0.18, p-value < 0.05). Younger individuals (18−44 years) have a higher rate of nicotine metabolism than older individuals (45−64 years and 65−89) (Geometric means: 0.53 vs. 0.42 and 0.31, respectively, p-values < 0.01) and individuals with lower body mass index (21−25 kg/m2) have a higher rate of nicotine metabolism than the rest (26−30 kg/m2 and 31−60 kg/m2) (Geometric means: 0.52 vs. 0.35 and 0.36, respectively-values < 0.01). Nicotine metabolic rates are useful biomarkers when reporting smoking status and biological differences between individuals.

Passive exposure to electronic cigarette aerosol in pregnancy: A case study of a family.

BACKGROUND: Passive exposure to the aerosols of electronic cigarettes (e-cigarettes) has been little studied. We assessed this exposure in late pregnancy in a woman and her 3-year-old child, exposed through e-cigarette use by another household member. METHODS: This prospective longitudinal case study involved a family unit consisting of an e-cigarette user, a pregnant woman who delivered an infant during the study, and the couple's older 3-year-old son. At 31, 36, and 40 weeks of the pregnancy, we measured biomarkers (nicotine metabolites, tobacco-specific nitrosamines, propanediols, glycerol, and metals) in the urine and hair of all three participants and in the saliva of the adults, in cord blood at delivery, and in the breast milk at the postpartum period. RESULTS: Samples from the e-cigarette user showed quantifiable concentrations of all analytes assessed (maximum urinary cotinine concentration, 4.9 ng/mL). Among samples taken from the mother, nicotine and its metabolites were found mainly in urine and also in saliva and hair, but not in cord blood. During the postpartum period, we found cotinine concentrations of 2.2 ng/mL in the mother's urine and 0.22 ng/mL in breast milk; 1,2-propanediol was generally detected in urine and saliva, but not in cord blood or breast milk. The maximum urinary cotinine concentration in the 3-year-old child was 2.6 ng/mL and propanediols also were detected in his urine. Nitrosamines were not detected in samples taken from the mother or the 3-year-old. Metals found in the refill liquid were detected at low levels in both the mother and the 3-year-old. CONCLUSIONS: We detected low but not negligible concentrations of e-cigarette-related analytes (including cord blood and breast milk) in an exposed pregnant non-user and in a 3-year-old child also living in the home. Passive exposure to e-cigarette aerosols cannot be disregarded and should be assessed in larger observational studies.

Exposure to secondhand aerosol from electronic cigarettes at homes: A real-life study in four European countries.

Electronic cigarette (e-cigarette) use emits potentially hazardous compounds and deteriorates indoor air quality. Home is a place where e-cigarettes may frequently be used amid its increasing prohibition in public places. This study assessed the real-life scenario of bystanders' exposure to secondhand e-cigarette aerosol (SHA) at home. A one-week observational study was conducted within the TackSHS project in four countries (Greece, Italy, Spain, and the United Kingdom) in 2019 including: 1) homes of e-cigarette users living together with a non-user/non-smoker; and 2) control homes with no smokers nor e-cigarette users. Indoor airborne nicotine, PM2.5, and PM1.0 concentrations were measured as environmental markers of SHA. Biomarkers, including nicotine and its metabolites, tobacco-specific nitrosamines, propanediol, glycerol, and metals were measured in participants' saliva and urine samples. E-cigarette use characteristics, such as e-cigarette refill liquid's nicotine concentration, e-cigarette type, place of e-cigarette use at home, and frequency of ventilation, were also collected. A total of 29 e-cigarette users' homes and 21 control homes were included. The results showed that the seven-day concentrations of airborne nicotine were quantifiable in 21 (72.4 %) out of 29 e-cigarette users' homes; overall, they were quite low (geometric mean: 0.01 µg/m3; 95 % CI: 0.01-0.02 µg/m3) and were all below the limit of quantification in control homes. Seven-day concentrations of PM2.5 and PM1.0 in e-cigarette and control homes were similar. Airborne nicotine and PM concentrations did not differ according to different e-cigarette use characteristics. Non-users residing with e-cigarette users had low but significantly higher levels of cotinine, 3'-OH-cotinine and 1,2-propanediol in saliva, and cobalt in urine than non-users living in control homes. In conclusion, e-cigarette use at home created bystanders' exposure to SHA regardless of the e-cigarette use characteristics. Further studies are warranted to assess the implications of SHA exposure for smoke-free policy.

Determination of soluble angiotensin-converting enzyme 2 in saliva samples and its association with nicotine.

INTRODUCTION: The Angiotensin-Converting Enzyme 2 (ACE2) is the main receptor of the SARS-CoV-2. There is contradictory evidence on how the exposure to nicotine may module the concentration of soluble ACE2 (sACE2). The aim of this study was to assess the association between nicotine and sACE2 concentrations in saliva samples. METHODS: Pooled analysis performed with data retrieved from two studies (n = 634 and n = 302). Geometric mean (GM) concentrations of sACE2, both total and relative to the total amount of protein in the sample, were compared according to sociodemographic variables and variables associated to nicotine. Multivariable linear regression models were fitted to explore the associations of sACE2 with nicotine adjusting for sex, age and body mass index. Spearman's rank-correlation coefficients were estimated between the concentrations of nicotine and cotinine, and pack-years, the concentration of relative sACE2 and the isoforms of sACE2. RESULTS: We observed a significant increase of 0.108‰ and 0.087 ng/µl in the relative and absolute salivary sACE2 GM concentrations, respectively, between the lowest and highest nicotine levels. Similar results were observed for cotinine. These associations did not change in the multivariable linear models. There was a low correlation of nicotine and cotinine concentration with the concentration of relative salivary sACE2 (rs = 0.153 and rs = 0.132, respectively), pack-years (rs = 0.222 and rs = 0.235, respectively) and with the concentration of isoform 40 KDa (rs = 0.193 and rs = 0.140, respectively). CONCLUSION: Salivary nicotine concentration seems to be limitedly associated with the concentration of sACE2.

Consumo actual de cigarrillos electrónicos entre estudiantes de secundaria que nunca han fumado / Current use of electronic cigarettes among never smoker high school students

Objetivo: Examinar si en España el uso de los cigarrillos electrónicos está asociado a la iniciación del consumo de nicotina entre los estudiantes de secundaria. Método: Análisis secundario de datos de la encuesta ESTUDES 2019, estudio transversal realizado a una muestra representativa de estudiantes entre 14 y 18 años. Seleccionamos los alumnos que nunca habían fumado (n = 16.705). Calculamos la prevalencia y estimamos los factores asociados al consumo de cigarrillos electrónicos al menos una vez en el mes anterior a la entrevista, con y sin nicotina. Resultados: La prevalencia de consumo actual de cigarrillos electrónicos entre estudiantes que nunca han fumado es del 2,5% (intervalo de confianza del 95% [IC 95%]: 2,2-2,9). El 0,1% (IC 95%: 0,08-0,2) reportó haber utilizado alguna vez líquidos con nicotina y el 2,4% (IC 95%: 2,1-2,8) siempre sin nicotina. Ser varón, menor de 17 años, hacer botellón y tener amigos habituales que consumen cannabis aumenta la probabilidad de consumo actual de cigarrillos electrónicos. Estas dos últimas variables parecen actuar como variables contextuales asociadas al consumo de cigarrillos electrónicos. Conclusiones: El porcentaje de estudiantes españoles que nunca han fumado, pero que consumen cigarrillos electrónicos actualmente, es menor que en los países de nuestro entorno, a excepción del Reino Unido. Solo uno de cada 1000 estudiantes españoles de secundaria que nunca han fumado se inicia en el consumo actual de nicotina con un cigarrillo electrónico. No obstante, debemos vigilar cómo evoluciona este indicador. (AU)

Objective: To test whether electronic cigarettes use among secondary school students in Spain is associated with initiating nicotine use. Method: Secondary analysis of the ESTUDES 2019 survey, a cross-sectional study conducted on a representative sample of students aged 14–18 years and selected students who had never smoked (n = 16,705). We computed the prevalence and estimated the factors associated with current electronic cigarettes use (at least once in the month before the interview), with and without nicotine. Results: The prevalence of current electronic cigarettes use among students who have never smoked is 2.5% (95% confidence interval [95%CI]: 2.2–2.9). 0.1% (95%CI: 0.08–0.2) declared using liquids with nicotine at least sometimes and 2.4% (95%CI: 2.1–2.8) using liquids always without nicotine. Being male and under 17 years of age, reporting binge drinking behavior, and having regular friends who use cannabis, increases the probability of current use of electronic cigarettes. The latter two variables seem to act as contextual variables associated with electronic cigarettes use. Conclusions: The percentage of Spanish never smoker students who currently use electronic cigarettes is lower than in neighboring countries, except for the United Kingdom. Only one in every 1000 Spanish students between 14 and 18 years old who have never smoked initiates the current use of nicotine with an electronic cigarette. However, we must monitor the evolution of this indicator. (AU)

Changes in the salivary cotinine cut-offs to discriminate smokers and non-smokers before and after Spanish smoke-free legislation.

INTRODUCTION: High levels of cotinine in non-smokers indicate passive exposure to tobacco smoke. This study aims to evaluate variations in salivary cotinine cut-offs to discriminate smokers and non-smokers before and after the implementation of smoke-free legislation (Law 28/2005 and Law 42/2010) in a sample of the adult population of Barcelona, Spain. METHODS: This longitudinal study analyzes salivary cotinine samples and self-reported information from a representative sample (n = 676) of the adult population from Barcelona before and after the approval of smoke-free legislation. We calculated the receiver operating characteristic (ROC) curves, to obtain optimal cotinine cut-off points to discriminate between smokers and non-smokers overall, by sex and age, and their corresponding sensitivity, specificity, and area under the curve. We used linear mixed-effects models, with individuals as random effects, to model the percentage change of cotinine concentration before and after the implementation of both laws. RESULTS: The mean salivary cotinine concentration was significantly lower post-2010 law (-85.8%, p < 0.001). The ROC curves determined that the optimal cotinine cut-off points for discriminating non-smokers and smokers were 10.8 ng/mL (pre-2005 law) and 5.6 ng/mL (post-2010 law), with a post-2010 law sensitivity of 92.6%, specificity of 98.4%, and an area under the curve of 97.0%. The post-2010 law cotinine cut-off points were 5.6 ng/mL for males and 1.9 ng/mL for females. CONCLUSION: The implementation of Spanish smoke-free legislation was effective in reducing secondhand smoke exposure and, therefore, also in reducing the cut-off point for salivary cotinine concentration. This value should be used to better assess tobacco smoke exposure in this population.

Measuring cigarette dependence: A comparison of two scales in two different groups of smokers.

INTRODUCTION: The Fagerström Test for Cigarette Dependence (FTCD) and the Cigarette Dependence Scale (CDS) are usually used to assess cigarette dependence in clinical- and population-based studies. Our objective was to compare these two scales within groups of smokers from both contexts. METHODS: The study was observational with smokers from a representative sample of the adult general population (n=188) and smokers attending a smoking cessation clinic in Barcelona, Spain (n=759). The FTCD and the CDS-5 (short version of 5 items) were used to assess cigarette dependence. We compared the standardized median scores obtained with both scales within each group of smokers by selected variables. To this aim, we re-scaled the scores of both scales to allow their comparison and assess their correlation within both groups. RESULTS: The scores obtained with both scales were highly correlated within both groups of smokers (p<0.001), indicating good agreement in the assessment of cigarette dependence. Nevertheless, higher standardized CDS-5 scores were observed more frequently in the population group overall (3.9 vs FTCD score=3.7, p=0.001), among women (4.5 vs 4.2; p<0.001), in the youngest group of smokers (3.9 vs 3.2; p<0.007) and in light smokers (time to the first cigarette >60 min; 1.7 vs 1.1; p<0.001). CONCLUSIONS: While the CDS-5 scored higher more frequently in the population group, the FTCD scored higher more frequently in the clinical group. These differences should be considered when designing either clinical- or population-based studies.

Acceptability and participation predictors for a pragmatic randomized controlled trial to test a smoking cessation intervention after discharge from mental health wards.

BACKGROUND AND AIM: Hospitalization is an ideal time to promote smoking cessation, but interventions are limited for supporting cessation maintenance after discharge. This study aimed to evaluate the acceptability of participating in a trial that tested the efficacy of an intensive telephone-based intervention for smokers after discharge. METHODS: Adult smokers admitted to mental health wards of six hospitals were invited to participate in the trial. We studied the study acceptance/decline rates by analyzing the characteristics of participants (e.g., sex, age, psychiatric disorder, smoking pattern) and hospitals (e.g., size, tobacco control implementation). We calculated adjusted odds ratios (aOR) to assess predictors of non-participation. RESULTS: Of 530 smokers that met the study inclusion criteria, 55.5% (n = 294) agreed to participate. Participant and non-participants were not different in sex, age, or psychiatric diagnosis. Compared to non-participants, participants had made more attempts to quit in the past year (66.1% vs 33.9%; p < 0.001) and reported higher abstinence rates during the hospital stay (66.7% vs. 33.3%; p = 0.05). Participation rates by hospital varied from 30.9% to 82.0% (p < 0.001). Predictors of non-participation were not having attempted to quit in the last year (aOR=2.42; 95%CI: 1.66-3.53) and low level of tobacco control in the hospital (aOR range: 1.79-6.39, p < 0.05). CONCLUSIONS: A telephone-based intervention to promote smoking cessation after discharge was accepted by half of the smokers with mental health disorders. Smokers that had attempted to quit previously and those that stayed in hospitals with a strong tobacco control policy were more likely to participate in the trial.

Association between biomarkers of tobacco consumption and lung cancer risk among daily smokers.

BACKGROUND: Biomarkers of tobacco consumption may play a role in the lung cancer risk assessment. However, the role of salivary biomarkers has not been well studied. The aim of this study is to assess the use of salivary biomarkers of tobacco consumption as lung cancer screening criterion. RESEARCH DESIGN AND METHODS: Data came from the Determinants of cotinine phase 3 project (Barcelona, 2013-2014). We compared the concentrations of TSNAs, including NNAL, NNN and NNK, and cotinine, in saliva samples of 142 daily smokers from the general population according to their risk of lung cancer. High risk of lung cancer was defined as per the inclusion criteria in the US National Lung Screening Trial (NLST) and in the Dutch-Belgian lung cancer screening trial (NELSON). RESULTS: Among daily smokers accomplishing the age criterion for lung cancer screening, salivary concentrations of cotinine, NNAL and NNK adjusted for sex were significantly higher (p-value < 0.05) in daily smokers at high risk of lung cancer compared to smokers not at high risk according to both NELSON and NLST criteria. CONCLUSIONS: Saliva concentrations of cotinine, NNAL and NNK may be used as additional criteria for lung cancer screening. Further research on this topic is guaranteed.

Smoking cessation interventions in substance use disorders treatment centers of Catalonia: The abandoned addiction. / Intervenciones para dejar de fumar en los centros de atención a las drogodependencias de Cataluña: La adicción abandonada.

Substance use disorders (SUD) treatment centers are an optimal setting for delivering smoking cessation interventions (SCI). This study aimed to examine the adoption of SCI in SUD treatment centers in Catalonia (Spain) as well as to assess their managers' views on the appropriateness and feasibility of providing SCI. Managers directly in charge of SUD treatment centers (n = 57) answered a 30-item on-line questionnaire. Data was obtained of 50 centers (87.7% response rate). Forty-six per cent of the centers provided some kind of SCI, but only 4.8% of the new patients were treated for smoking cessation. Managers reported that 73.3% of mental health professionals working in SUD centers had not been trained in SCI. Sixty-four per cent of managers agreed that all health professionals should deliver SCI. Those centers offering SCI attended more patients and were more likely to have professionals trained in SCI than those not offering SCI. The implementation of SCI in SUD treatment centers in Catalonia was suboptimal. Continuing education and training should be provided for all health professionals working in SUD centers. Not systematically delivering SCI to patients in treatment for other SUD means missing opportunities to reduce health and economic costs while perpetuating a smoking culture.

Los centros de tratamiento de drogodependencias son un recurso óptimo para realizar intervenciones para la cesación tabáquica (ICT). El objetivo de este estudio fue examinar la implementación de ICT en la Red de centros de Atención a las Drogodependencias (CAS) de Cataluña, así como evaluar las opiniones sobre la adecuación y viabilidad de la provisión de ICT. Los responsables de los CAS (n = 57) contestaron un cuestionario on-line compuesto por 30 ítems. Se obtuvieron datos de 50 centros (87,7% tasa de respuesta). El 46% de los CAS ofrecía algún tipo de ICT, pero sólo un 4,8% de los nuevos pacientes eran tratados para dejar de fumar. Además, los responsables informaron que el 73,3% de los profesionales que trabajaban en los CAS no había recibido formación en ICT. El 64% de los responsables estaba de acuerdo que todos los profesionales deberían realizar ICT. Aquellos centros que ofrecían ICT visitaban más pacientes y era más probable que tuviesen profesionales formados en ICT, comparado con los centros que no ofrecían ICT. La implementación de ICT en los CAS de Cataluña era subóptima. Se debería facilitar formación continuada a los profesionales de los CAS. No intervenir sobre el consumo de tabaco en pacientes en tratamiento por otras drogodependencias significa perder oportunidades para reducir costes en salud y económicos mientras perpetuamos una cultura fumadora.

Environmental and individual exposure to secondhand aerosol of electronic cigarettes in confined spaces: Results from the TackSHS Project†.

Secondhand electronic cigarette (e-cigarette) aerosol (SHA) might impair indoor air quality and expose bystanders. This study aims to investigate exposure to SHA in controlled conditions of enclosed settings simulating real-world scenario. An experiment was performed in a car and in a room, in which SHA was generated during a 30-minute ad libitum use of an e-cigarette. The experiment was replicated on five consecutive days in each setting. We measured PM2.5 , airborne nicotine concentrations, and biomarkers of exposure to SHA, such as nicotine metabolites, tobacco-specific nitrosamines, propylene glycol, and glycerol in bystanders' saliva samples before, during, and after the exposure period. Self-reported health symptoms related to exposure to SHA were also recorded. The results showed that the highest median PM2.5 concentration was recorded during the exposure period, being 21 µg/m3 in the room setting and 16 µg/m3 in the car setting-about twofold increase compared to the baseline. Most concentrations of the airborne nicotine and all biomarkers were below the limit of quantification in both settings. Bystanders in both settings experienced some short-term irritation symptoms, expressed as dry throat, nose, eyes, and phlegm. In conclusion, short-term use of an e-cigarette in confined spaces increased indoor PM2.5 level and caused some irritation symptoms in bystanders.

The right to smoke and the right to smoke-free surroundings: international comparison of smoke-free psychiatric clinic implementation experiences.

BACKGROUND: In Scandinavia, people with a severe mental disorder have a reduced life expectancy of 15-20 years compared with the general public. Smoking is a major contributor, and smoke-free policies are increasingly adopted in psychiatric clinics around the world. We compared potential facilitators and barriers among staff and management, for the implementation of smoke-free psychiatric clinics. AIMS: To investigate the attitudes and experiences regarding smoke-free policies among managers and staff involved in the implementation processes of smoke-free psychiatric clinics at hospitals in Malmö (Sweden) and Barcelona (Spain). METHOD: We used a qualitative methodology, with 15 semi-structured interviews. The interviews were conducted with each participant individually, and were subsequently transcribed. The data were analysed with systematic text condensation. RESULTS: There were notable differences in how the smoke-free policies were carried out and experienced, and attitudes regarding the policy changes differed in the two settings. Key differences were the views on the right to smoke in compulsory care and to stay in smoke-free surroundings supported by smoking cessation intervention; the prioritisation of staff facilitation of smoking breaks; and views on smoking and smoke-free psychiatry. In contrast, participants agreed on the importance of staff education and management support. A smoking ban by law and belonging to a network of smoke-free hospitals were also relevant. CONCLUSIONS: Staff education, and support from staff and management for the patients' right to stay in smoke-free surroundings, facilitated successful implementation of smoke-free policies in the psychiatric clinics, whereas supporting the right to smoke was a barrier.
