The relationship between workplace, job stress and nurses' tobacco use: a review of the literature

Predictors of Substance Use Risk in Nurse Anesthetists

BACKGROUND

Certified registered nurse anesthetists (CRNAs) are exposed daily to highly addictive substances and stressful work environments, placing them at risk for substance use disorders (SUDs). Previous research, which is scarce, indicated that drugs of choice were opioids and propofol. Therefore, the purpose of this study was to investigate predictors of SUD risk using the World Health Organization Alcohol, Smoking and Substance Involvement Screening Test.

METHOD

From June to July 2020, an online survey was sent via the American Association of Nurse Anesthesiology Research Survey Service to 3,000 CRNAs with a response of approximately 225 members.

RESULTS

CRNAs were found to be at a moderate risk for SUDs in the following categories: 10.27% for tobacco, 23.56% for alcohol, and 6.28% for cannabis. Regression analysis by substance category includes robust, differing models in this homogeneous sample. Predictors for all three models include a collection of demographic variables, religiosity, anxiety, difficulties due to anxiety, depression, substance use history, contact with the American Association of Nurse Anesthesiology Peer Assistance Program, and organizational support.

CONCLUSION

Over 10% of CRNAs are at risk for developing tobacco use disorder, and almost one quarter of those surveyed are at a moderate risk for developing alcohol use disorder. These data are of concern and may indicate a shift of preferred substances used by CRNAs from controlled substances to alcohol.

Perceived stigma, substance use and self-medication in night-shift healthcare workers: a qualitative study

Background

Many risk factors related to altered circadian rhythms impact the health of night-shift hospital workers (NSHW), resulting in mental and somatic disorders. Easy access to psychoactive substances (PS) may facilitate addictive behaviors in NSHW. They are also exposed to a stressful work environment, which may further affect sleep quality. This study aimed to explore the link between sleep deprivation, work-related psychosocial stress and psychoactive substance use as a self-medication response in NSHW.

Methods

Qualitative study to verify the plausibility of the self-medication theory applied to addictive behaviors. Semi-structured interviews (N = 18 NSHW) and thematic analysis, following consolidated criteria for reporting qualitative research recommendations.

Results

Stigma against NSHW was a primary element of a stressful work environment. The stressful and stigmatizing environment, together with night-shift work, further affected NSHW sleep and their mental and physical health. The use of PS appeared to be for self-medication, encouraged by social and professional environments, source(s) of stress, discrimination, and isolation. The work environment, through aggravated sleep disorders, led NSHW to use non-prescribed sleeping pills. Alcohol after work and smoking were used as a social break but also as a means to reduce stress.

Conclusion

Anti-stigma interventions in the healthcare setting and screening of mental/somatic disorders in NSHW can help reduce harmful self-medication behaviors and improve hospital care in the COVID-19 era.

Barriers to introduction of smoke-free workplaces in Central Europe: example of the Czech Republic

OBJECTIVES

Smoking at the workplace has a negative impact both on employers' economic interests and employees' health. The aim of this study is to describe the current situation, mainly barriers in implementation and resources in the Czech Republic as an example of a Central European country.

METHODS

We synthesised relevant review papers with our knowledge of the local situation based upon professional experience of both authors.

RESULTS

Despite smoke-free laws, some EU workers are still exposed to passive smoking during working hours. The main barriers towards smoke-free workplace implementation are the lack of resources, perception of smoking as a norm, and exceptions for leading personalities and their smoking. Social support increases smoking cessation effectiveness. Low availability of local smoking cessation services is an overall problem in Central Europe.

CONCLUSIONS

The working environment influences smoking habits. Smoking cessation support is cost-effective not only for the smoking employee but for employers as well. Smoking cessation resources should be available during the working day. No exceptions should be made as they serve as barriers to a smoke-free working environment.

Alcohol/substance use and occupational/post-traumatic stress in paramedics

Background:

Paramedics work in high-pressure environments and experience traumatic events, which contribute to high levels of occupational and post-traumatic stress. Such stress can result in alcohol and substance misuse in other health professionals, but this relationship has not been examined in paramedics. This review is the first exploration of the literature on this.

Methods:

A systematic literature review was conducted using PRISMA guidelines, with databases searched using terms relevant to paramedics and alcohol/substance use. Studies were analysed using descriptive statistics for quantitative data and thematic analysis for qualitative information.

Findings:

Eleven studies were identified. Nine studies examined alcohol use; seven examined substance use; five examined both. Alcohol and smoking may be linked to occupational stress.

Conclusions:

The nature and extent of alcohol and substance use in relation to occupational and post-traumatic stress among paramedics need further investigation to facilitate advice and support.

Strategies to promote nurses' health: A qualitative study with student nurses

Developing strategies to support student nurses' health is a global priority for healthcare organisations and governments. This is because emerging international evidence indicates that improvements in student nurses' health are required to increase the longevity of careers and reduce the loss of time, skill and financial cost of sickness absence and workforce exit. However, we do not know what intervention strategies student nurses think would support their health. The study aim was to explore student nurses' views on factors that influence health-related behaviours and strategies that could improve health. Data were collected through participatory activities during focus groups with student nurses in Scotland. Analysis was theoretically informed and involved mapping to the Behaviour Change Wheel framework. Students identified several factors that influenced health-related behaviours. Four were ranked most important: knowledge, culture, time constraints, and stress. Strategies student nurses thought should be prioritised to improve nurses' health-related behaviours were: stimulating a health-promoting environment by reviewing shift work, improving workplace support, increasing staffing levels, subsidising and role-modelling of healthy food and exercise; and creating applied health-promoting curricula by integrating time and stress management training and lifestyle advice into nursing education. Educational and environmental interventions are needed to support student nurses' health.

Psychological and Behavioral Correlates of Readiness to Stop Smoking

Accruing evidence strongly suggests that the motivation to give up smoking is a crucial predictor of tobacco cessation attempt. However, even motivated people often fail in their attempts and relapse is very common, even if most people who smoke are confident that the desire to quit is enough to change and maintain abstinence. According to this framework, the main objective of the current study was to identify psychological and lifestyle patterns that might characterize people who smoke cigarettes with different motivations to quit. A secondary aim was to compare the characteristics of people who are currently smoking with people who stopped or never smoked. A convenient sample of 360 volunteers (179 women, 181 men), with a mean age of 55 years (SD = 14.33), participated in this study. Participants completed a battery of psychological and behavioral scales aimed at assessing psychological characteristics as well as dependence level and readiness to stop. Our results strongly suggest that the behavior of people who smoke differs as a function of specific psychological variables. People who currently smoke may fall into two different clusters: In the first one, they have a healthy lifestyle and high self-perceived vitality and vigor, whereas those who fall in the second report lower psychological well-being and an unhealthier lifestyle. Unfortunately, the actual lifestyle does not seem to modulate the motivation to quit, and consequently, people keep on smoking anyway, although some participants tend to adopt compensative behaviors. However, the adoption of a healthier lifestyle might favor a successful cessation attempt once a ready-to-stop motivation level is achieved.

Factors Contributing to Nurse Productivity in Public Hospitals in Surabaya, Indonesia

This study aimed at examining the factors that contribute to nursing productivity in public hospitals in Surabaya. Data relating to the respondents' characteristics and their productivity were collected using a questionnaire incorporating the Behaviorally Anchored Rating Scale. The samples were drawn from 31 nurses form the emergency room (ER) and 29 nurses from the intensive care unit (ICU) wards of a public hospital in Surabaya, Indonesia, of whom, 52 nurses participated voluntarily and indicated their willingness to respond by signing an informed consent form. The chi-square and Fisher's exact test was used to determine associations between the determinants (demographic characteristics, lifestyle and nutritional status) and productivity and the strength of association was identified by using logistic regression. The results from this study found that gender had borderline significant and duration of work experience had a significant association with nurse productivity. Therefore, gender and duration of working experience are factors which should be taken into consideration when managing human resources working in ERs and ICUs while basic nursing competencies are clearly also important factors in maintaining productivity.

Prevalence of Smoking Among 4 Licensed Types of Nursing Personnel in Japan: An Epidemiological Study

There is a high prevalence of smoking among nursing personnel, despite the fact that nursing is a health care profession. In Japan there are 4 types of licensed nursing professionals. However, the prevalence of smoking among different types of licensed personnel has not been clarified. We attempted to clarify the prevalence of smoking among the various types of licensed nursing personnel and the factors associated with it. Among the members of the Japanese Nursing Association, 6000 nurses were randomly selected. The participants were sent a questionnaire on smoking habits, personal characteristics, lifestyle habits, and employment status by mail. Current smokers accounted for 1.3% of public health nurses, 4.0% of midwives, 8.2% of registered nurses, and 16.3% of assistant nurses. The license type of nursing personnel was a factor significantly associated with current smoking.

Health-related behaviours of nurses and other healthcare professionals: A cross-sectional study using the Scottish Health Survey

AIMS

To estimate the prevalence and co-occurrence of health-related behaviours among nurses in Scotland relative to other healthcare workers and those in non-healthcare occupations.

DESIGN

Secondary analysis of nationally representative cross-sectional data, reported following STROBE guidelines.

METHODS

Five rounds (2008-2012) of the Scottish Health Survey were aggregated to estimate the prevalence and co-occurrence of health-related behaviours (smoking, alcohol consumption, physical activity, fruit/vegetable intake). The weighted sample (n = 18,820) included 471 nurses (3%), 433 other healthcare professionals (2%), 813 unregistered care workers (4%), and 17,103 in non-healthcare occupations (91%). Logistic regression models compared the prevalence of specific health-related behaviours and principal component analysis assessed co-occurrence of health-related behaviours between occupational groups.

RESULTS

Nurses reported significantly better health-related behaviours relative to the general working population for smoking, fruit/vegetable intake, and physical activity. No significant difference was found for alcohol consumption between occupational groups. Nurses reported lower levels of harmful co-occurring behaviours (tobacco smoking and alcohol consumption) and higher levels of preventive behaviours (physical activity and fruit/vegetable intake) compared with the general working population. Other healthcare professionals had the lowest level of harmful health behaviours and the highest level of preventive health behaviours. Health-related behaviours were poorest among unregistered care workers.

CONCLUSION

Nurses' health-related behaviours were better than the general population but non-adherence to public health guidelines was concerning.

IMPACT

Nurses play an important role in health promotion through patient advice and role-modelling effects. To maximise their impact, healthcare providers should prioritise increasing access to healthy food, alcohol awareness, and smoking cessation programmes.

Do nurses' personal health behaviours impact on their health promotion practice? A systematic review

BACKGROUND

There is a growing expectation in national and international policy and from professional bodies that nurses be role models for healthy behaviours, the rationale being that there is a relationship between nurses' personal health and the adoption of healthier behaviours by patients. This may be from patients being motivated by, and modelling, the visible healthy lifestyle of the nurse or that nurses are more willing to promote the health of their patients by offering public health or health promotion advice and referring the patient to support services.

METHODS

An integrated systematic review was conducted to determine if nurses' personal health behaviour impacted on (1) their health promotion practices, and (2) patient responses to a health promotion message. Medline, CINAHL, SCOPUS, and PsycINFO databases were searched. A narrative synthesis was conducted.

RESULTS

31 studies were included in the review. No consistent associations were noted between nurses' weight, alcohol use, or physical activity level and their health promotion practice, although smoking appeared to negatively impact on the likelihood of discussing and engaging in cessation counselling. Nurses who reported confidence and skills around health promotion practice were more likely to raise lifestyle issues with patients, irrespective of their own personal health behaviours. The two studies included in the review that examined patient responses noted that the perceived credibility of a public health message was not enhanced by being delivered by a nurse who reported adopting healthy behaviours.

CONCLUSIONS

Although it is assumed that nurses' personal health behaviour influences their health promotion practice, there is little evidence to support this. The assertion in health care policy that nurses should be role models for healthy behaviours assumes a causal relationship between their health behaviours and the patient response and adoption of public health messages that is not borne out by the research evidence.

Ambiente ocupacional e o consumo de substâncias psicoativas entre enfermeiros

Resumo Objetivo Analisar a relação entre o ambiente de trabalho e o consumo de substâncias psicoativas entre enfermeiros hospitalares. Métodos Estudo transversal e descritivo, realizado com enfermeiros de três instituições hospitalares públicas localizados em um município da Região Sul do Brasil, sendo duas de média complexidade e uma de alta complexidade. A população deste estudo foi composta por 221 enfermeiros. Com base nesse número, calculou-se o tamanho amostral por estratos, considerando-se a proporção de 50%, nível de confiança de 95% e erro máximo de 5%, o que resultou no número mínimo de 175 participantes. Mediante a estratificação proporcional por instituição definiu-se o mínimo de 103 enfermeiros da alta complexidade e 36 de cada instituição de média complexidade. Adotou-se como critérios de inclusão: trabalhar na instituição há pelo menos um ano e não estar afastado por licença. A coleta de dados foi realizada entre outubro de 2015 e abril de 2016. Na coleta de dados utilizaram-se informações sociodemográficas e ocupacionais, o Nursing Work Index - Revised e o Alcohol, Smoking and Substance Involvement Screening Test. Os dados foram analisados no programa Statistical Package for Social Sciences, versão 20.0. Inicialmente, verificou-se a normalidade pelo teste de Kolmogorov-Smirnov. Foram realizadas análises descritivas, por frequências absoluta e relativa para as variáveis categóricas; e medianas e medidas de dispersão para as numéricas. Resultados Álcool, tabaco e sedativos foram as substâncias mais consumidas. Renda mensal apresentou correlação positiva com o consumo de álcool entre enfermeiros dos hospitais de média complexidade (p=0,01). No hospital de alta complexidade, o consumo de álcool relacionou-se negativamente a relação médico-enfermeiro (p=0,03). Autonomia, relação médico-enfermeiro e suporte organizacional estiveram correlacionados negativamente ao uso de sedativos (p<0,01; p<0,01; p=0,02, respectivamente). Conclusão Quanto mais desfavorável o ambiente de trabalho do enfermeiro, sobretudo na relação com médicos, suporte organizacional e autonomia, maior foi o consumo de substâncias psicoativas.

Tobacco prevention and reduction with nursing students: A non-randomized controlled feasibility study

BACKGROUND

Prevalence of tobacco use among nurses and nursing students is disproportionally high in Germany. However, from a public health perspective they are considered to be an important group for delivering smoking cessation interventions. As delivery of tobacco-related treatment depends on own smoking status, smoking prevention and cessation among the nursing professions is indicative for improving nurse and public health.

OBJECTIVE

To evaluate the feasibility and effects of a comprehensive tobacco prevention and reduction program on psychosocial and environmental factors related to smoking behavior of nursing students.

METHODS

Between 2014 and 2015, a non-randomized, controlled feasibility study was conducted in 12 schools of nursing with 397 nursing students in Germany. Students in the intervention group received a program (ASTRA) consisting of an introductory session, steering committee workshop, stress prevention lessons, evidence-based smoking cessation intervention, and action project. Six months after baseline assessment, change in smoking-related protective and risk factors was determined. Secondary endpoints included smoking behavior.

RESULTS

The program was implemented in total in 5 of 7 intervention schools. About one third of smoking nursing students participated in a cessation intervention. The program seems to do better than a minimal intervention booklet in four primary outcomes: perceived descriptive, subjective, and injunctive norms towards smoking and nursing as well as perceived social support. As anticipated, there was no change in smoking behavior.

CONCLUSIONS

The applied approach is feasible and able to improve important smoking-related norm perceptions of student nurses and perception of social support. However, additional context measures to influence the settings of nursing education currently rather supporting smoking seem to be necessary in order to promote smoking cessation among nursing students and to scale up implementation of the program.

Should nurses be role models for healthy lifestyles? Results from a modified Delphi study

AIM

To explore the expectation that nurses should be role models for healthy behaviours.

BACKGROUND

Nurses are expected to be role models for healthy behaviours. Whether this is a realistic and acceptable expectation has not been explored.

DESIGN

Modified Policy Delphi study with two rounds of data collection.

METHOD

Purposive sampling was used to explore areas of agreement and disagreement among six stakeholder groups who influence nursing roles: practising nurses, nursing students, service users, policy makers, workforce development leads and stakeholders working in nurse education. Two rounds of a modified Policy Delphi study were conducted between February - June 2015. The first round used telephone interviews for an open exploration of opinions. The second round used attitude statements to explore convergence and divergence of opinions across stakeholder groups. Responses were analysed thematically.

RESULTS

Policy and professional discourse that asserts that nurses should be healthy role models was seen as unrealistic and unhelpful. Contrary to the view that nurses should epitomize and demonstrate healthy behaviours to encourage patients and to be credible in advice, stakeholders agreed that it was more important to be seen as 'human' and understand the challenges of health behaviour change. Student and practising nurses did not see role modelling healthy behaviours as a reasonable professional expectation.

CONCLUSIONS

The findings challenge the assumptions underpinning the argument that nurses be healthy role models. Further research is needed to understand the views of frontline nurses and to further explore avenues by which health services staff health can be improved.

The 'switch on-switch off model': Strategies used by nurses to mentally prepare and disengage from work

There is considerable research on the experience of nurses during both their work and non-work time. However, we know relatively little about the strategies nurses use immediately before and immediately after their shift. This crossover period, from one shift to another, has critical impact for patient outcomes. The aim of this qualitative study was to explore strategies nurses employ to mentally prepare for their shift (switch on), and mentally disengage after the end of it (switch off). Eleven Greek hospital nurses were recruited for the study. Interviews were audio-taped and analysed using a content analysis approach. Five themes were identified as strategies nurses use to mentally prepare and disengage from their shift: (i) personal care/grooming; (ii) religious rituals; (iii) nicotine/caffeine; (iv) social interaction; and (v) listening to music. Nurses reported using the same strategies before and after their shift, but for different purposes. The authors propose a 'switch on-switch off' model to describe the process of mental preparation and mental disengagement from work. The switch-on/off approach represents an opportunity to increase nurses' resilience and identify individual and organizational factors that contribute to patient outcomes.

The mental health of nurses in acute teaching hospital settings: a cross-sectional survey

Background

Nursing is an emotionally demanding profession and deficiencies in nurses’ mental wellbeing, characterised by low vitality and common mental disorders, have been linked to low productivity, absenteeism and presenteeism. Part of a larger study of nurses’ health, the aim of this paper was to describe the mental health status and related characteristics of nurses working in two acute metropolitan teaching hospitals.

Methods

A cross sectional survey design was used.

The Registered and Enrolled Nurse workforce, employed on any form of contract, at two teaching hospitals in Sydney Australia were invited to participate. The survey tool was compiled of validated tools and questions. Family and medical history and health risk-related characteristics, current psycho-active medications, smoking status, alcohol intake, eating disorders, self-perceived general health, mental health and vitality, demographic, social and occupational details were collected.

Results

A total of 1215 surveys were distributed with a usable response rate of 382 (31.4%). Altogether 53 nurses (14%) reported a history of mental health disorders, of which n = 49 (13%) listed diagnoses of anxiety and/or depression; 22 (6%) were currently taking psychoactive medication. Symptoms that could potentially indicate a mental health issue were more common, with 248 (65.1%) reporting they had experienced symptoms sometimes or often in the last 12 month.

Nurses had better mental health if they had better general health, lived with a spouse/ partner rather than alone, had fewer symptoms, sleep problems or disordered eating behaviours, were not an informal carer and did not work nights. Nurses had greater vitality if they were male, had better general health, fewer sleep problems or symptoms generally and lived with a spouse/ partner rather than alone; less vitality if they were an informal carer or had disordered eating.

Conclusion

Nurses and their managers should strive to create workplaces where working practices promote nurses’ health and wellbeing, or at least are configured to minimise deleterious effects; where both nurses and their managers are aware of the potential for negative effects on the mental health of the workforce; where cultures are such that this can be discussed openly without fear of stigma or denigration.

Job strain and health-related lifestyle: findings from an individual-participant meta-analysis of 118,000 working adults

OBJECTIVES

We examined the associations of job strain, an indicator of work-related stress, with overall unhealthy and healthy lifestyles.

METHODS

We conducted a meta-analysis of individual-level data from 11 European studies (cross-sectional data: n = 118,701; longitudinal data: n = 43,971). We analyzed job strain as a set of binary (job strain vs no job strain) and categorical (high job strain, active job, passive job, and low job strain) variables. Factors used to define healthy and unhealthy lifestyles were body mass index, smoking, alcohol intake, and leisure-time physical activity.

RESULTS

Individuals with job strain were more likely than those with no job strain to have 4 unhealthy lifestyle factors (odds ratio [OR] = 1.25; 95% confidence interval [CI] = 1.12, 1.39) and less likely to have 4 healthy lifestyle factors (OR = 0.89; 95% CI = 0.80, 0.99). The odds of adopting a healthy lifestyle during study follow-up were lower among individuals with high job strain than among those with low job strain (OR = 0.88; 95% CI = 0.81, 0.96).

CONCLUSIONS

Work-related stress is associated with unhealthy lifestyles and the absence of stress is associated with healthy lifestyles, but longitudinal analyses suggest no straightforward cause-effect relationship between work-related stress and lifestyle.

Job strain and tobacco smoking: an individual-participant data meta-analysis of 166,130 adults in 15 European studies

Background

Tobacco smoking is a major contributor to the public health burden and healthcare costs worldwide, but the determinants of smoking behaviours are poorly understood. We conducted a large individual-participant meta-analysis to examine the extent to which work-related stress, operationalised as job strain, is associated with tobacco smoking in working adults.

Methodology and Principal Findings

We analysed cross-sectional data from 15 European studies comprising 166 130 participants. Longitudinal data from six studies were used. Job strain and smoking were self-reported. Smoking was harmonised into three categories never, ex- and current. We modelled the cross-sectional associations using logistic regression and the results pooled in random effects meta-analyses. Mixed effects logistic regression was used to examine longitudinal associations. Of the 166 130 participants, 17% reported job strain, 42% were never smokers, 33% ex-smokers and 25% current smokers. In the analyses of the cross-sectional data, current smokers had higher odds of job strain than never-smokers (age, sex and socioeconomic position-adjusted odds ratio: 1.11, 95% confidence interval: 1.03, 1.18). Current smokers with job strain smoked, on average, three cigarettes per week more than current smokers without job strain. In the analyses of longitudinal data (1 to 9 years of follow-up), there was no clear evidence for longitudinal associations between job strain and taking up or quitting smoking.

Conclusions

Our findings show that smokers are slightly more likely than non-smokers to report work-related stress. In addition, smokers who reported work stress smoked, on average, slightly more cigarettes than stress-free smokers.

Three-year follow-up of attitudes and smoking behaviour among hospital nurses following enactment of France's national smoke-free workplace law

OBJECTIVE

This study evaluated among hospital nurses the smoking status, knowledge and attitudes regarding smoking cessation services, and smoking behaviour 3years after the implementation of smoke-free workplace law (decree no. 2006-1386).

METHODS

A descriptive study was undertaken in a public referral hospital in the South of France. Between February and April 2010, a questionnaire was distributed to the nurses. Data on demographic information, smoking status, behaviour and attitudes regarding smoking addiction, and knowledge regarding smoking cessation services were collected. Changes in nurses' smoking habits were studied through a former study conducted in this hospital a year after the law had come into effect.

RESULTS

Three years after the enactment of the smoking ban, 30% (30% in 2008) reported themselves as current smokers, 26% (25% in 2008) as ex-smokers and 44% (45% in 2008) as non-smokers. Among smokers, 72% (68% in 2008) declared they had decreased tobacco consumption during working hours and 50% (29% in 2008) daily cigarette consumption. The majority of nurses (88%) supported the smoke-free law. A higher percentage of smokers than non smokers have knowledge of smoking cessation services. The smoking prevalence among hospital nurses seemed to have remained constant between 2008 and 2010 despite a better compliance with the law.

CONCLUSIONS

France's national smoke-free workplace law is associated with a reduction in tobacco consumption and exposure to second-hand smoke in nurses but not smoking prevalence. The other measures of the MPOWER package have to be reinforced.

Psychosocial job stress and immunity: a systematic review

The purpose of this review was to provide current knowledge about the possible association between psychosocial job stress and immune parameters in blood, saliva, and urine. Using bibliographic databases (PubMed, PsychINFO, Web of Science, Medline) and the snowball method, 56 studies were found. In general, exposure to psychosocial job stress (high job demands, low job control, high job strain, job dissatisfaction, high effort-reward imbalance, overcommitment, burnout, unemployment, organizational downsizing, economic recession) had a measurable impact on immune parameters (reduced NK cell activity, NK and T cell subsets, CD4+/CD8+ ratio, and increased inflammatory markers). The evidence supports that psychosocial job stresses are related to disrupted immune responses but further research is needed to demonstrate cause-effect relationships.
