Treating Smoking in Adults With Co-occurring Acute Psychiatric and Addictive Disorders

There's no smoke without fire: Smoking in smoke-free acute mental health wards

BACKGROUND

People who smoke with serious mental illness carry disproportionate costs from smoking, including poor health and premature death from tobacco-related illnesses. Hospitals in New Zealand are ostensibly smoke-free; however, some mental health wards have resisted implementing this policy.

AIM

This study explored smoking in acute metal health wards using data emerging from a large sociological study on modern acute psychiatric units.

METHODS

Eighty-five in-depth, semi-structured interviews were conducted with staff and service users from four units. Data were analysed using a social constructionist problem representation approach.

RESULTS

Although high-level smoke-free policies were mandatory, most participants disregarded these policies and smoking occurred in internal courtyards. Staff reasoned that acute admissions were not the time to quit smoking, citing the sceptres of distress and possibly violence; further, they found smoking challenging to combat. Inconsistent enforcement of smoke-free policies was common and problematic. Many service users also rejected smoke-free policies; they considered smoking facilitated social connections, alleviated boredom, and helped them feel calm in a distressing environment - some started or increased smoking following admission. A minority viewed smoking as a problem; a fire hazard, or pollutant. No one mentioned its health risks.

CONCLUSION

Psychiatric wards remain overlooked corners where hospital smoke-free policies are inconsistently applied or ignored. Well-meaning staff hold strong but anachronistic views about smoking. To neglect smoking cessation support for people with serious mental illness is discriminatory and perpetuates health and socioeconomic inequities. However, blanket applications of generic policy are unlikely to succeed. Solutions may include myth-busting education for service users and staff, local champions, and strong managerial support and leadership, with additional resourcing during transition phases. Smoke-free policies need consistent application with non-judgemental NRT and, potentially, other treatments. Smoking cessation would be supported by better designed facilities with more options for alleviating boredom, expressing autonomy, facilitating social connections, and reducing distress.

Supporting smoking cessation and preventing relapse following a stay in a smoke-free setting: a meta-analysis and investigation of effective behaviour change techniques

BACKGROUND AND AIMS

Admission to a smoke-free setting presents a unique opportunity to encourage smokers to quit. However, risk of relapse post-discharge is high, and little is known about effective strategies to support smoking cessation following discharge. We aimed to identify interventions that maintain abstinence following a smoke-free stay and determine their effectiveness, as well as the probable effectiveness of behaviour change techniques (BCTs) used in these interventions.

METHODS

Systematic review and meta-analyses of studies of adult smokers aged ≥ 18 years who were temporarily or fully abstinent from smoking to comply with institutional smoke-free policies. Institutions included prison, inpatient mental health, substance misuse or acute hospital settings. A Mantel-Haenszel random-effects meta-analysis of randomized controlled trials (RCTs) was conducted using biochemically verified abstinence (7-day point prevalence or continuous abstinence). BCTs were defined as 'promising' in terms of probable effectiveness (if BCT was present in two or more long-term effective interventions) and feasibility (if BCT was also delivered in ≥ 25% of all interventions).

RESULTS

Thirty-seven studies (intervention n = 9041, control n = 6195) were included: 23 RCTs (intervention n = 6593, control n = 5801); three non-randomized trials (intervention n = 845, control n = 394) and 11 cohort studies (n = 1603). Meta-analysis of biochemically verified abstinence at longest follow-up (4 weeks-18 months) found an overall effect in favour of intervention [risk ratio (RR) = 1.27, 95% confidence interval (CI) = 1.08-1.49, I²  = 42%]. Nine BCTs (including 'pharmacological support', 'goal-setting (behaviour)' and 'social support') were characterized as 'promising' in terms of probable effectiveness and feasibility.

CONCLUSIONS

A systematic review and meta-analyses indicate that behavioural and pharmacological support is effective in maintaining smoking abstinence following a stay in a smoke-free institution. Several behaviour change techniques may help to maintain smoking abstinence up to 18 months post-discharge.

Evaluating the Associations Between Exposure to Tobacco Interventions During Inpatient Treatment and Substance Use Outcomes: Findings From a Natural Experiment

OBJECTIVE

In this study, we took advantage of a natural experiment that occurred within a substance use disorders (SUD) treatment setting which first saw the implementation of an evidence-based practice (EBP) for tobacco cessation, followed by the implementation of a tobacco-free policy (TFP) that included a campus-wide tobacco ban. We sought to examine how implementation of the EBP and TFP was associated with substances use outcomes, in addition to tobacco use, up to 3-months posttreatment.

METHODS

Data were collected from patients in a substance use disorders treatment program at baseline, discharge, 1-, and 3-months posttreatment. Using a quasi-experimental design and generalized estimating equations, we modelled how patients' (N = 480) exposure to one of 3 interventions (1: treatment as usual [TAU], 2: EBP, and 3: EBP + TFP) was associated with overall abstinence from tobacco, alcohol, and other substances over time. Measures of tobacco use frequency, amount, and quit attempts were also modelled among a sub-sample of participants who self-reported using tobacco before treatment.

RESULT

Exposure to the EBP + TFP was associated with increased tobacco abstinence (odds ratio [OR] = 1.93, 95% confidence interval [CI] [1.29, 2.90]) over time, including decreases in tobacco use frequency (OR = 0.78, 95% CI [0.68, 0.89]) and amount (OR = 0.80, 95% CI [0.67, 0.96]), and increased in likelihood of making a quit attempt (OR = 1.75, 95% CI [1.10, 2.80]) compared to TAU. Exposure was not associated with alcohol and/or other substance use.

CONCLUSIONS

Comprehensive tobacco interventions that include EBP + TFP can promote tobacco cessation and reduced tobacco use following inpatient SUD treatment, without adversely affecting the use of other substances.

Tailored Web-Based Smoking Interventions and Reduced Attrition: Systematic Review and Meta-Analysis

Background

The increasing number of internet users presents an opportunity to deliver health interventions to large populations. Despite their potential, many web-based interventions, including those for smoking cessation, face high rates of attrition. Further consideration of how intervention features impact attrition is needed.

Objective

The aim of this systematic review is to investigate whether tailored web-based smoking cessation interventions for smokers are associated with reduced rates of attrition compared with active or passive untailored web-based interventions. The outcomes of interest were dropout attrition at 1-, 3-, 6-, and 12-month follow-ups.

Methods

Literature searches were conducted in May 2018 and updated in May 2020 on MEDLINE (Medical Literature Analysis and Retrieval System Online), PsycINFO (Psychological Information), EMBASE (Excerpta Medica dataBASE), CINAHL (Cumulated Index to Nursing and Allied Health Literature), Scopus, and the Cochrane Tobacco Addiction Group Specialized Register with the following search terms: smoking cessation, tailored, or web- or internet-based. Included studies were published in English before or in May 2020 using a randomized controlled trial design. Studies were restricted to those with web-based delivery, a tailored intervention group, an untailored control group, and a reported outcome of smoking cessation. Studies were assessed for methodological quality using the Cochrane Risk of Bias tool. Two reviewers independently extracted the study characteristics and the number of participants lost to follow-up for each treatment group.

Results

A total of 13 studies were included in the systematic review, of which 11 (85%) were included in the meta-analysis. Tailoring had no statistically significant effect on dropout attrition at 1-month (risk ratio [RR]=1.02, 95% CI 0.95-1.09; P=.58; I²=78%), 3-month (RR=0.99, 95% CI 0.95-1.04; P=.80; I²=73%), 6-month (RR=1.00, 95% CI 0.95-1.05; P=.90; I²=43%), or 12-month (RR=0.97, 95% CI 0.92-1.02; P=.26; I²=28%) follow-ups. Subgroup analyses suggested that there was a statistically significant effect of tailoring between the active and passive subgroups at 1-month (P=.03), 3-month (P<.001), and 6-month (P=.02) follow-ups but not at 12-month follow-up (P=.25).

Conclusions

The results suggest that tailoring of web-based smoking cessation interventions may not be associated with reduced rates of dropout attrition at 1-, 3-, 6-, or 12-month follow-ups. Significant differences between studies that include untailored active and passive control groups suggest that the role of tailoring may be more prominent when studies include a passive control group. These findings may be because of variability in the presence of additional features, the definition of smokers used, and the duration of smoking abstinence measured. Future studies should incorporate active web-based controls, compare the impact of different tailoring strategies, and include populations outside of the Western countries.

Tobacco use and tobacco services in California substance use treatment programs

BACKGROUND

California has one of the lowest smoking rates in the U.S. However, the California substance use disorder (SUD) treatment system collects no information on tobacco use. We explored smoking prevalence among persons enrolled in 20 residential SUD treatment programs, and whether persons who wanted help with quitting smoking received such help.

METHODS

Treatment program clients (N = 562) were surveyed about their smoking behavior and about tobacco-related services they received. Self-report smoking status was verified via expired carbon monoxide (CO) measurement. Multivariate analyses assessed whether clients who wanted help with quitting smoking received tobacco-related services (ask, advise, referral, counseling, pharmacotherapy) RESULTS: Using client self-report and expired CO, smoking prevalence in this sample was estimated at 68.9 %. Among smokers, mean cigarettes per day (CPD) was 9.7 (SD = 7.6), 58.8 % had made a quit attempt in the past year, 32.7 % were considering quitting smoking in the next 30 days, and 37.9 % wanted help with quitting. Clients who wanted help with quitting, compared to those not wanting help, were more likely to receive advice on how to quit, and tobacco-related counseling, referral, and pharmacotherapy.

CONCLUSION

In this study, wanting help with quitting was associated with receiving tobacco related services. Nonetheless, fewer than half of the smokers in SUD treatment wanted help with quitting, and many who wanted help did not receive it. Given the high prevalence of smoking, and associated consequences for both general health and SUD recovery, SUD treatment systems should ensure tobacco-related assessment and intervention for all smokers.

Patient-Physician Discussions on Lung Cancer Screening: A Missed Teachable Moment to Promote Smoking Cessation

INTRODUCTION

Little is known about whether patients and physicians perceive lung cancer screening (LCS) as a teachable moment to promote smoking cessation or the degree to which physicians in "real world" settings link LCS discussions with smoking cessation counseling. We sought to characterize patient and physician perspectives of discussions about smoking cessation during LCS.

METHODS

We conducted a qualitative study (interviews and focus groups) with 21 physicians and 28 smokers screened in four diverse hospitals. Transcripts were analyzed for characteristics of communication about smoking cessation and LCS, the perceived effect on motivation to quit smoking, the degree to which physicians leverage LCS as a teachable moment to promote smoking cessation, and suggestions to improve patient-physician communication about smoking cessation in the context of LCS.

RESULTS

Patients reported that LCS made them more cognizant of the health consequences of smoking, priming them for a teachable moment. While physicians and patients both acknowledged that smoking cessation counseling was frequent, they described little connection between their discussions regarding LCS and smoking cessation counseling. Physicians identified several barriers to integrating discussions on smoking cessation and LCS. They volunteered communication strategies by which LCS could be leveraged to promote smoking cessation.

CONCLUSIONS

LCS highlights the harms of smoking to patients who are chronic, heavy smokers and thus may serve as a teachable moment for promoting smoking cessation. However, this opportunity is typically missed in clinical practice.

IMPLICATIONS

LCS highlights the harms of smoking to heavily addicted smokers. Yet both physicians and patients reported little connection between LCS and tobacco treatment discussions due to multiple barriers. On-site tobacco treatment programs and post-screening messaging tailored to the LCS results are needed to maximize the health outcomes of LCS, including smoking quit rates and longer-term smoking-related morbidity and mortality.

Factors associated with the successful completion of a substance rehabilitation programme at a psychiatric training hospital

Background

Comorbid psychiatric and substance use disorders are common and present several treatment challenges.

Aim

The aim of this study was to determine which patient and substance factors are associated with the completion of a substance rehabilitation programme in psychiatric inpatients.

Setting

The study was conducted at the Substance Rehabilitation Unit (SRU) at Weskoppies Hospital, a psychiatric training hospital in South Africa, which offers a 6-week programme at the hospital for psychiatric inpatients.

Methods

This descriptive, retrospective hospital-based study was carried out comparing completers and non-completers of the SRU programme with respect to patient and substance factors. All patients accepted into the SRU during 2013–2014 were included (n = 119). Data were collected over a year (2016–2017) from the clinical files, SRU referral forms, SRU attendance register, hospital computerised demographic records, nursing notes and administration files using a data collection sheet designed by the researchers for this study. Comparison between completers and non-completers was performed using Chi-Square or Fisher’s Exact tests.

Results

The SRU accepted 119 patients from January 2013 to December 2014. The majority of the sample were involuntary patients (n = 39), 30–49 years old (n = 57), male (n = 89), unmarried (n = 112), never having received a disability grant (n = 27), unemployed (n = 96) and with a Grade 8–11 education (n = 49). Substance-induced psychotic disorders (n = 39), schizophrenia (n = 29) and bipolar disorders (n = 22) were found to be common. Frequent medical comorbidities included head injury (n = 27), cardiovascular disease (n = 18) and HIV reactivity (n = 7). Cannabis (n = 98), alcohol (n = 94) and nicotine (n = 90) were the most frequently used substances. Level of education (p = 0.004), disability grant status (p = 0.004), Nyaope use (p = 0.001) and nicotine use (p = 0.049) were statistically seen to be significantly associated with completion. Psychiatric diagnoses and general medical comorbidity were not associated with completion.

Conclusions

This study has yielded several results in areas that have not yet been well researched in South Africa. Risk factors for non-completion may include lower levels of education, being on a disability grant and using Nyaope or nicotine, but may vary in different settings. Future research should focus on identifying further factors that may affect completion of substance rehabilitation in psychiatric inpatients, the role of disability grants in patients with co-occurring disorders and the effect of Nyaope and nicotine use on treatment outcomes in this population. Effective and accessible interventions to assist vulnerable patients also need to be identified.

Evaluating the short-term impact of a tobacco-free policy in an inpatient addiction treatment setting

PURPOSE

Tobacco use is highly prevalent within addiction treatment settings, despite the potential benefits that cessation may provide to patients' psychosocial functioning and overall sobriety. Moreover, tobacco cessation is often insufficiently addressed in addiction treatment programs, although evidence suggests that tobacco control policies, such as access to evidence-based treatment or tobacco-free policies, may be effective. The objective of our study was to evaluate the impact of the implementation of these two tobacco control policies in an inpatient addiction treatment centre.

METHODS

Using a 3-group quasi-experimental design, we examined how the implementation of the Ottawa Model for Smoking Cessation (OMSC) and a subsequent campus-wide tobacco ban influenced patients' overall smoking status, frequency, amount used per day, and quit attempts during treatment, compared to usual care. Participants (N = 397) responded to a comprehensive questionnaire upon admission and discharge from an addiction treatment program. We used generalized linear mixed modelling to measure changes over time while accounting for relevant sociodemographic covariates.

RESULTS

Patients exposed to a more comprehensive tobacco control environment (i.e., the OMSC, plus complete tobacco ban) were over 80% less likely to report having used tobacco during treatment, compared to patients exposed to usual care (AOR = 0.17, 95% CI [0.05-0.63]). Receiving treatment in this setting also contributed to a 35% decrease in the average number of days patients used tobacco compared to usual care (AOR = 0.65, 95% CI [0.53-0.98]), and a 27% decrease in the average number of cigarettes used per day compared to usual care (AOR = 0.73, 95% CI [0.58-0.93]).

CONCLUSION

Comprehensive tobacco control policy interventions within inpatient addiction treatment hospitals promote tobacco cessation. Such interventions should include a combination of evidence-based treatment for patients and environmental restrictions to discourage tobacco use. The results of our study suggest that, within inpatient addiction treatment settings, use of the OMSC in combination with a campus-wide tobacco ban may be more effective than usual care or the OMSC alone.

Cigarette use is increasing among people with illicit substance use disorders in the United States, 2002-14: emerging disparities in vulnerable populations

BACKGROUND AND AIMS

While cigarette smoking has declined over time, it is not known whether this decline has occurred similarly among individuals with substance use disorders (SUDs) in the United States (US). The current study estimated trends in smoking from 2002 to 2014 among US individuals with and without SUDs.

DESIGN

Linear time trends of current smoking prevalence were assessed using logistic regression models.

SETTING

United States; data were drawn from the 2002 to 2014 National Household Survey on Drug Use (NSDUH), an annual US cross-sectional study.

PARTICIPANTS

A representative, population-based sample of US individuals age 12 yeas and older (total analytical population: n = 723 283).

MEASUREMENTS

Past-month current smoking was defined as having smoked at least 100 lifetime cigarettes and reporting smoking part or all of at least one cigarette during the past 30 days. Respondents were classified as having any SUD if they met criteria for abuse or dependence for one or more of the following illicit drugs: cannabis, hallucinogens, inhalants, tranquilizers, cocaine, heroin, pain relievers, simulants and sedatives. A second SUD variable included all drugs listed above excluding cannabis use disorder (CUD). An additional variable included respondents who met criteria for cannabis abuse or dependence.

FINDINGS

Among those with any SUD, the prevalence of smoking did not change from 2002 to 2014 (P = 0.08). However, when CUDs were separated from other SUDs, a significant increase in prevalence of smoking was observed among those with SUDs excluding CUDs (P < 0.001), while smoking decreased among those with CUDs (P < 0.001). Smoking declined among those without SUDs (P < 0.001). In 2014, smoking remained significantly more common among those with any SUD (55.48%), SUDs excluding CUDs (63.34%) and CUDs (51.34%) compared with those without these respective disorders (18.16, 18.55 and 18.64%; P < 0.001).

CONCLUSIONS

The prevalence of cigarette smoking in the United States increased from 2002 to 2014 among people with substance use disorders (SUDs) excluding cannabis use disorders (CUDs) and declined among those with CUDs and without SUDs. In 2014, the prevalence of smoking was multifold higher among those with SUDs, including CUDs, compared with those without SUDs.

Innovative approaches to support smoking cessation for individuals with mental illness and co-occurring substance use disorders

INTRODUCTION

Tobacco remains the leading preventable cause of death in the US, accounting for over 520,000 deaths annually. While the smoking prevalence has declined over the past 50 years, those with mental illness and addictive disorders continue to smoke at high levels and with significant tobacco-related health problems. Areas covered: This review highlights the epidemiology, contributing factors, and evidence-base for intervening upon tobacco use in those with mental illness and addictive disorders. Historically underprioritized, a growing body of literature supports treating tobacco within mental health and addiction treatment settings. Critically, treating tobacco use appears to support, and not harm, mental health recovery and sobriety. This review also summarizes novel, emerging approaches to mitigate the harms of cigarette smoking. Expert commentary: People with mental illness and addictive disorders have a high prevalence of tobacco use with serious health harms. Treating tobacco use is essential. Evidence-based strategies include individual treatments that are stage-matched to readiness to quit and combine cessation medications with behavioral therapies, supported by smoke-free policies in treatment settings and residential environments. Emerging approaches, with a focus on harm reduction, are electronic nicotine delivery systems and tobacco regulatory efforts to reduce the nicotine content in cigarettes, thereby reducing their addiction potential.
