Involuntary smoking cessation: a treatment option in chemical dependency programs for women and children

Smoking cessation interventions for pregnant women attending treatment for substance use disorders: A systematic review

BACKGROUND AND AIMS

Up to 95% of pregnant women seeking treatment for alcohol and other drug (AOD) use smoke tobacco. Previous reviews indicate few effective smoking cessation treatments for this group. This updated review aimed to identify and measure the efficacy of smoking cessation interventions trialled among pregnant women in AOD treatment settings who smoke tobacco.

METHODS

A narrative synthesis was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Studies involving psychological, behavioural or pharmacological interventions used to treat tobacco use, including electronic nicotine delivery systems, for pregnant women of any age, who smoked tobacco and were seeking/receiving treatment, or in post-treatment recovery for AOD concerns, were reviewed. MEDLINE, PsycINFO, CINAHL, EMBASE and ProQuest databases, grey literature and reference lists were searched, and field experts were contacted for unpublished study data. The Effective Public Health Practice Project tool assessed study quality. The review was pre-registered with PROSPERO no. CRD42018108777.

RESULTS

Seven interventions (two randomised controlled trials, two single-arm pilot studies, two program evaluations and one causal comparative study) treating 875 women were identified. All were United States (US)-based and targeted women with drug dependence, but not alcohol dependence. Three interventions used contingency management, five provided behavioural counselling, and one offered nicotine replacement therapy. All reported reductions in cigarette consumption; one contingency management-based study demonstrated higher abstinence rates compared with controls at treatment-end that were not maintained at follow-up. Four of six studies were rated as methodologically weak and one unpublished study was not rated.

CONCLUSIONS

Conclusions about the efficacy of smoking interventions for pregnant women with alcohol and other drug concerns who also smoke tobacco are hindered by the paucity of available data and poor methodological quality of included studies.

Interventions for pregnant women who use tobacco and other substances: a systematic review protocol

INTRODUCTION

The prevalence of tobacco smoking in pregnancy remains elevated in some disadvantaged populations of women. One group is those who use alcohol and/or other psychoactive substances during pregnancy, with tobacco use prevalence estimates ranging from 71% to 95%. Although effective evidence-based cessation treatments exist, few women with co-occurring substance use problems successfully stop smoking during pregnancy. There is limited information about treatments that specifically target this group and a summary of the available research is required to assist and enhance the development of innovative cessation interventions. This article describes a protocol for a comprehensive review of studies that have trialled behavioural and/or pharmacological tobacco cessation interventions in populations of pregnant women who are nicotine dependent and use alcohol and/or other psychoactive substances.

METHODS AND ANALYSIS

The review will undertake literature searches in MEDLINE, PsycINFO, CINAHL, EMBASE and ProQuest databases, as well as the grey literature. Studies of any design methodology will be included if they describe changes to tobacco smoking behaviours in quantitative terms. No restriction on year of publication or published language will apply. Participants include pregnant women of any age, who smoke tobacco, who are seeking or having treatment, or in post-treatment recovery for the use of psychoactive substances. Interventions are any psychological, behavioural or pharmacological treatments used to treat tobacco use. Outcome measures are any that quantitatively report abstinence or reductions in participant tobacco consumption. Key details and tobacco-related outcomes from included studies will be extracted and tabulated before being narratively synthesised. The systematic review protocol has been developed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols guidelines.

ETHICS AND DISSEMINATION

Ethics approval is not required. Findings will be disseminated via peer-reviewed literature, conference presentations, media and social media.

Contingency management interventions for tobacco and other substance use disorders in pregnancy

Contingency management (CM) is an effective intervention for reducing use of licit and illicit substances in a variety of populations. Pregnant women are a vulnerable population with much to gain from effective interventions for substance use disorders, and for whom CM interventions may be especially well-suited. We reviewed the literature on CM interventions among pregnant women with tobacco and other substance use disorders with 3 aims: (a) describe the effectiveness of CM for reducing use of tobacco and other substances during pregnancy, (b) describe the effects of CM interventions on infant outcomes, and (c) identify needs for future research on CM in pregnancy. Our search strategy revealed 27 primary studies of CM in pregnancy. CM was effective in the majority of studies targeting nicotine abstinence, and results were mixed in studies targeting illicit substances. A variety of methodologies were used within the relatively small number of studies making it difficult to identify underlying mechanisms. Also, very few studies reported maternal and infant outcomes, and significant effects of CM were only apparent when secondary analyses pooled data from multiple studies. Furthermore, there is extremely limited data on the cost effectiveness of CM interventions in pregnancy. Future research should address these 3 areas to better determine the ultimate value of CM as an efficacious treatment for pregnant women with substance use disorders. (PsycINFO Database Record

Smoking cessation for substance misusers: A systematic review of qualitative studies on participant and provider beliefs and perceptions

INTRODUCTION

Smoking prevalence among those in substance misuse treatment remains much higher than the general population, despite evidence for effective cessation interventions that do not negatively impact substance misuse outcomes. This systematic review summarises qualitative data on barriers and facilitators to smoking cessation for people in substance misuse treatment, participants' and providers' perceptions about effects of smoking cessation on substance misuse treatment, timing of intervention delivery and aspects of interventions perceived to be effective.

METHODS

Systematic review of qualitative studies and thematic synthesis of published qualitative data.

RESULTS

10939 records and 132 full texts were screened. 22 papers reporting on 21 studies were included. Key themes identified were: strong relationships between smoking and other substance misuse; environmental influences; motivation; mental health; aspects of interventions perceived to be effective/ineffective; barriers and facilitators to intervention implementation; smoking bans/restrictions; and relationships with professionals. Many service users were motivated toward smoking cessation but were not offered support. Some felt interventions should be delivered after substance misuse treatment, whilst others felt concurrent/dual interventions would be beneficial, due to strong associations between smoking and other substances. Treatment providers felt they lacked training and resources for supporting smoking cessation, and were concerned about impact on substance misuse outcomes.

CONCLUSIONS

Many substance misusers who also smoke are motivated to quit but perceive a lack of support from professionals. Additional training and resources are required to enable professionals to provide the support needed. More research is required to develop enhanced packages of care for this deprived group of smokers.

The use of financial incentives in promoting smoking cessation

OBJECTIVE

Cigarette smoking is the leading cause of preventable death in the United States and world. Despite the availability of numerous therapies for smoking cessation, additional efficacious interventions are greatly needed. We provide a narrative review of published studies evaluating financial incentives for smoking cessation and discuss the parameters important for ensuring the efficacy of incentive interventions for smoking cessation.

METHODS

Published studies that evaluated the impact of incentives to promote smoking cessation and included an appropriate control or comparison condition were identified and reviewed.

RESULTS

Incentives are efficacious for promoting smoking abstinence across the general population of smokers as well as substance abusers, adolescents, patients with pulmonary disease, patients with serious mental illness and other challenging subgroups. To develop and implement an effective incentive treatment for smoking, special attention should be paid to biochemical verification of smoking status, incentive magnitude and the schedule of incentive delivery.

CONCLUSION

Consistent with the extensive literature showing that incentives are effective in reducing illicit drug use, a large body of evidence supports their effectiveness in reducing smoking. Continued efforts are warranted to further develop and disseminate incentive-based treatments for smoking cessation across clinical settings and populations.

Substance abuse treatment for mothers: treatment outcomes and the impact of length of stay

This article examines the treatment outcomes of 305 women enrolled in a comprehensive, residential substance abuse treatment program for pregnant and parenting women and their children. The women were assessed at intake and three times in the year after discharge. Analyses focused on change in client functioning over time, and investigating the impact of length of stay in treatment on client outcomes. Comparisons of clients' functioning before and after treatment suggest significant improvements in a number of domains, including substance use, employment, legal involvement, mental health, parenting attitudes, and risky behaviors. For most outcome domains, results suggest that longer treatment stays are associated with more positive outcomes.

Smoking stage of change is associated with retention in a smoke-free residential drug treatment program for women

Prochaska and DiClemente's Transtheoretical Model predicts dropout from substance-abuse treatment. However, it is not known whether readiness to quit smoking is associated with attrition from drug treatment programs with smoking restrictions. This study examined the relationship between smoking characteristics, smoking stage of change, and both length of stay (LOS) and discharge type among 75 perinatal substance abusers attending a smoke-free residential treatment program. URICA scores predicted LOS (P=.0004) and discharge type (P=.01). Women in action and maintenance remained in treatment longer and were more likely to complete treatment compared to those in precontemplation. Findings were not accounted for by addiction severity. Women with little interest in quitting smoking may have difficulty adhering to smoking restrictions during treatment for other drug problems, resulting in increased attrition. Alternatively, smoking stage of change may be a "proxy" for overall readiness to change in this population.

Incorporating nicotine dependence into addiction treatment

An addiction treatment program devoted two years to preparing to become a smokefree treatment unit that addressed nicotine dependence as another drug dependency. Data collected from September 1990 to July 1995 on 263 admissions before becoming smokefree and 2182 admissions after making the transition revealed that going smokefree did not affect the incidence of premature discharges or aggressive behavior, and did not change the overall rate of program completion by either smokers or nonsmokers. During the first three months after going smokefree, the program completion rate dropped for both smokers and nonsmokers; by the fourth month, it had returned to previous levels. Seventeen months after going smokefree, the program completion rate was higher than it had ever been. This suggests that the drop in the program completion rate was due to the disruption caused by a significant programmatic change and not due to the unit's smokefree status, and that the increasing experience of staff in treating nicotine dependence resulted in improved patient outcomes.
