Association Between Utilization of Quitline Services and Probability of Tobacco Abstinence in Low-Income Smokers

A Safety Net Tobacco Use Cessation Resource: Quitline Service Usage, 2019

INTRODUCTION

Quitlines are free, accessible evidence-based services that may provide an important resource for people facing barriers to clinical treatment for cessation of tobacco use.

METHODS

Using 2019 intake data from the National Quitline Data Warehouse, we examined quitline service usage, stratified by sociodemographic characteristics. Only US quitlines reporting service type data were included (n = 40 [of 51]). Callers (aged ≥12 years) who registered with a quitline, reported current use of a tobacco product, and received at least 1 service comprised the analytic data. Chi-square tests examined differences in quitline services received by participant characteristics.

RESULTS

In 2019, 182,544 people reporting current use of a tobacco product received at least 1 service from a quitline in 39 states and the District of Columbia. Among them, 80.4% had attained less than a college or university degree and 70.4% were uninsured or enrolled in Medicaid or in Medicare (aged <65 years). By educational attainment (aged ≥25 years), receipt of cessation medications ranged from 59.4% of callers with a college or university degree to 65.0% of callers with a high school diploma (P < .001). The range by insurance coverage was 59.3% of callers with private insurance to 74.7% of callers with Medicare (aged <65 years) (P < .001).

CONCLUSION

Quitlines served as a resource for low-SES populations in 2019, providing cessation services to many people who may face barriers to clinical cessation treatment. Strengthening and expanding quitlines may help to increase cessation among populations with a disproportionately high prevalence of tobacco product use and improve the health and well-being of people in the US.

Gender Differences in the Interrelations Among Social Support, Stressful Life Events, and Smoking Cessation in People With Severe Mental Illnesses

BACKGROUND

Social support and stressful life events (SLEs) have been found to be influential factors for smoking cessation in the general population, but little is known about these factors among smokers with severe mental illnesses (SMIs) and whether their associations with smoking cessation differ by gender.

AIMS

To examine the association between social support and smoking cessation as mediated by SLEs in people with SMI and to examine whether the interrelations among social support, SLEs, and smoking cessation differ by gender.

METHODS

A population sample of 4,610 American lifetime adult smokers with schizophrenia, bipolar disorder, or major depressive disorder were identified in a limited public use data set of the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions. Four mediation and moderated mediation models were used to examine gender differences in the interrelations among social support (total and three subscales of the Interpersonal Support Evaluation List-12), SLEs (summative score of positive responses to 16 types experienced in past year and related to health, job, death, or legal situations), and smoking status in prior year.

RESULTS

Total, appraisal, and tangible support among females exerted indirect effects on smoking cessation via decreasing SLE scores. Among males, only belonging support exerted an indirect effect on smoking cessation via an increased SLE score.

CONCLUSIONS

Findings suggest that interventions focusing on improving social support should be a priority for those working with smokers with SMI.

Successful Optimization of Tobacco Dependence Treatment in the Emergency Department: A Randomized Controlled Trial Using the Multiphase Optimization Strategy

STUDY OBJECTIVE

Tobacco dependence treatment initiated in the hospital emergency department (ED) is effective. However, trials typically use multicomponent interventions, making it difficult to distinguish specific components that are effective. In addition, interactions between components cannot be assessed. The Multiphase Optimization Strategy allows investigators to identify these effects.

METHODS

We conducted a full-factorial, 24 or 16-condition optimization trial in a busy hospital ED to examine the performance of 4 tobacco dependence interventions: a brief negotiation interview; 6 weeks of nicotine replacement therapy with the first dose delivered in the ED; active referral to a telephone quitline; and enrollment in SmokefreeTXT, a free short-messaging service program. Study data were analyzed with a novel mixed methods approach to assess clinical efficacy, cost-effectiveness, and qualitative participant feedback. The primary endpoint was tobacco abstinence at 3 months, verified by exhaled carbon monoxide using a Bedfont Micro+ Smokerlyzer.

RESULTS

Between February 2017 and May 2019, we enrolled 1,056 adult smokers visiting the ED. Odd ratios (95% confidence intervals) from the primary analysis of biochemically confirmed abstinence rates at 3 months for each intervention, versus control, were: brief negotiation interview, 1.8 (1.1, 2.8); nicotine replacement therapy, 2.1 (1.3, 3.2); quitline, 1.4 (0.9, 2.2); SmokefreeTXT, 1.1 (0.7, 1.7). There were no statistically significant interactions among components. Economic and qualitative analyses are in progress.

CONCLUSION

The brief negotiation interview and nicotine replacement therapy were efficacious. This study is the first to identify components of ED-initiated tobacco dependence treatment that are individually effective. Future work will address the scalability of the brief negotiation interview and nicotine replacement therapy by offering provider-delivered brief negotiation interviews and nicotine replacement therapy prescriptions.

Ask-Advise-Connect: Differential Enrollment and Smoking Cessation Outcomes Between Primary Care Patients Who Received Quitline-Delivered Treatment in Spanish vs English

PURPOSE

This study examined differences in Quitline treatment enrollment, engagement, and smoking cessation outcomes among primary care patients preferring Spanish and English using the evidence-based tobacco treatment Ask-Advise-Connect.

METHODS

Ask-Advise-Connect was implemented April 2013 through February 2016 in a large safety-net health system to connect smokers with treatment via a link in the electronic health record. Rates of treatment enrollment, engagement, acceptance of nicotine replacement therapy, and smoking abstinence (self-reported and biochemically confirmed) were compared at 6 months among patients who received treatment in Spanish and English using χ ² tests. Logistic regression examined language and nicotine replacement therapy and their interaction as predictors of abstinence.

RESULTS

The smoking status of 218,915 patients was assessed and recorded in the electronic health record. Smoking prevalence was 8.4% among patients preferring Spanish and 27.0% among those preferring English. Spanish-preferring patients were less likely to enroll in treatment (10.7% vs 12.0%, χ ² = 12.06, P = .001) yet completed more counseling calls when enrolled (median = 2 vs 1, P <.001). Patients who received treatment in Spanish (vs English) were twice as likely to be abstinent at 6 months (self-reported: 25.1% vs 14.5%, odds ratio [OR] = 1.98, 95% CI, 1.62-2.40; biochemically confirmed: 7.6% vs 3.7%, OR = 2.13, 95% CI, 1.52-2.97). Receipt of nicotine replacement therapy increased abstinence for all patients and language did not interact with nicotine replacement therapy to predict abstinence.

CONCLUSIONS

Automated point-of-care approaches such as Ask-Advise-Connect have great potential to reach Spanish-preferring smokers. Those who received tobacco treatment in Spanish (vs English) demonstrated better engagement and cessation outcomes.

Characteristics of Patients Engaging in Quitline Counseling After an Electronic Referral

INTRODUCTION

Proactive, electronic referral of primary care patients to quitlines has great potential to provide evidence-based tobacco-cessation assistance to tobacco users. However, the quitline contact rates and engagement of individuals beyond 1 counseling call are poor. This study examines the characteristics of electronically referred patients who engage with the quitline.

METHODS

This cross-sectional study included 2,407 primary care patients who reported using tobacco and accepted an electronic referral to the quitline. Outcomes included contact, enrollment, and receipt of ≥2 counseling sessions from the quitline. All measures were assessed from the electronic health record. The association of patient characteristics and outcomes was evaluated using logistic regression modeling with generalized estimating equation methods. Data were collected in 2016‒2018 and were analyzed in 2020.

RESULTS

Among 2,407 referred patients, 794 (33.0%) were contacted; of those, 571 enrolled (71.9%); and of those, 240 (42.0%) engaged in ≥2 quitline counseling sessions. In multivariable analyses, older adults (aged 50-64 and ≥65 years) were significantly more likely to be contacted (OR=2.32, 95% CI=1.6, 3.4) and to receive ≥2 counseling sessions (OR=2.34, 95% CI=1.2, 4.7) than those aged 18-34 years. Those with both Medicare and Medicaid insurance coverage were more likely than those with Medicaid only to be contacted (OR=1.71, 95% CI=1.4, 2.2), to enroll (OR=1.84, 95% CI=1.2, 2.9), and to receive ≥2 counseling sessions (OR=1.83, 95% CI=1.2, 2.9).

CONCLUSIONS

The current quitline phone-based approach is less likely to engage younger adults and those with Medicaid coverage; however, there is a need to improve quitline engagement across all patients. Identification and testing of alternative engagement approaches are needed.

It Takes Two to Tango: Patients' and Providers' Perspectives in Tobacco Cessation and Head/Neck Cancer

BACKGROUND

Tobacco cessation among patients with head/neck cancer continues to be challenging despite evidence that cessation improves treatment outcomes. The purpose of this study was to understand barriers/facilitators to tobacco cessation among patients with head/neck cancer and health care providers and to obtain perspectives toward the development of a patient-centered tobacco cessation intervention.

MATERIALS AND METHODS

In-depth qualitative interviews with 10 health care providers and 21 patients with head/neck cancer (12 inpatients and 9 outpatients) who were current or former smokers.

RESULTS

Health was a common motivator to quit among patients. Although most patients indicated that their health care provider asked and advised them to quit, they were unaware of cessation resources. Suggestions for a tobacco cessation program included involvement of former smokers, health care provider involvement/counseling, supporting written materials, and incorporating follow-up and family support. Health care providers identified patients' anger/frustration associated with the disease, social/demographic issues, and poor quality of life as the three most frequent challenges in treating patients. Although all providers reported asking about tobacco use, 70% emphasized a lack of formal training in tobacco cessation and lack of time. Their suggestions for a cessation program included having a "quarterback" responsible for this component with support from the entire health care team and continuity between outpatient and inpatient services to promote cessation, prevent relapse, and highlight the importance of follow-up and social support.

CONCLUSION

There is great interest and need, both from patients and providers, for tobacco cessation services in the oncology setting tailored for patients with head/neck cancer in the context of cancer care.

IMPLICATIONS FOR PRACTICE

Although the combination of pharmacotherapy and cognitive-behavioral intervention is the standard evidence-based treatment for tobacco dependence, it must be adapted to meet the needs and wants of patients and providers to be effective. This study provides an in-depth examination of such needs among patients with head and neck cancer and providers in the context of cancer care. Providers and patients emphasized the need of having a trained health care provider dedicated to providing tobacco cessation through seamless integration between outpatient and inpatient services as well as follow-up with an emphasis on family involvement throughout the process.

Healthcare resources attributable to child tobacco smoke exposure

Background

Tobacco smoke exposure (TSE) places an economic toll on the U.S. healthcare system. There is a gap in the literature on pediatric emergency department (ED) and urgent care related healthcare costs and utilization specific to tobacco smoke-exposed patients. The objectives were to assess pediatric ED visits, urgent care visits and hospital admissions longitudinally, and baseline visit costs among tobacco smoke-exposed children (TSE group) relative to unexposed children (non-TSE group).

Methods and findings

We conducted a retrospective study using electronic medical records of 380 children ages 0–17 years in the TSE group compared to 1,140 in the non-TSE group propensity score matched via nearest neighbor search by child age, sex, race, and ethnicity. Linear and Poisson regression models were used. Overall, children had a mean of 0.19 (SE = 0.01) repeat visits within 30-days, and 0.69 (SE = 0.04) pediatric ED visits and 0.87 (SE = 0.03) urgent care visits over 12-months following their baseline visit. The percent of children with ≥ 1 urgent care visit was higher among the TSE group (52.4%) than the non-TSE group (45.1%, p = 0.01). Children in the TSE group (M = $1,136.97, SE = 76.44) had higher baseline pediatric ED visit costs than the non-TSE group (M = $1,018.96, SE = 125.51, p = 0.01). Overall, children had 0.08 (SE = 0.01) hospital admissions over 12-months, and the TSE group (M = 0.12, SE = 0.02) had higher mean admissions than the non-TSE group (M = 0.06, SE = 0.01, p = 0.02). The child TSE group was at 1.85 times increased risk of having hospital admissions (95% CI = 1.23, 2.79, p = 0.003) than the non-TSE group.

Conclusions

Tobacco smoke-exposed children had higher urgent care utilization and hospital admissions over 12-months, and higher pediatric ED costs at baseline. Pediatric ED visits, urgent care visits, and hospitalizations may be opportune times for initiating tobacco control interventions, which may result in reductions of preventable acute care visits.

Race differences in predictors of weight gain among a community sample of smokers enrolled in a randomized controlled trial of a multiple behavior change intervention

African Americans have disproportionate rates of post-cessation weight gain compared to non-Hispanic whites, but few studies have examined this weight gain in a multiracial sample of smokers receiving evidence-based treatment in a community setting. We examined race differences in short-term weight gain during an intervention to foster smoking cessation plus weight management.

Data were drawn from the Best Quit Study, a randomized controlled trial conducted via telephone quitlines across the U.S. from 2013 to 2017. The trial tested the effects on cessation and weight gain prevention of adding a weight control intervention either simultaneously with or sequentially after smoking cessation treatment. African Americans (n = 665) and whites (n = 1723) self-reported smoking status and weight during ten intervention calls. Random effects longitudinal modeling was used to examine predictors of weight change over the intervention period (average 16 weeks).

There was a significant race × treatment effect; in the simultaneous group, weight increased for African Americans at a faster rate compared to whites (b = 0.302, SE = 0.129, p < 0.05), independent of smoking status, age, baseline obesity, and education. After stratifying the sample, the effect of treatment group differed by race. Education level attenuated the rate of weight gain for African Americans in the simultaneous group, but not for whites.

African Americans receiving smoking and weight content simultaneously gained weight faster than whites in the same group; however, the weight gain was slower for African Americans with higher educational attainment. Future studies are needed to understand social factors associated with treatment receptivity that may influence weight among African American smokers.

Quitting the quitline: a qualitative study of patient experience of electronic referrals to quitlines

BACKGROUND

The use of electronic referrals (eReferrals) to state quitlines (QLs) for tobacco-using patients is a promising approach for addressing smoking cessation on a large scale. However, QL contact, enrollment, and completion rates are low. The purpose of this study was to examine the eReferral to QL process from the patient's perspective in order to inform strategies for improving QL engagement.

METHODS

We conducted interviews with 55 patients who agreed to an eReferral at a primary care visit to 1 of 8 safety-net community health centers in Cuyahoga County, Ohio (September 2017-August 2018). Interviews were designed to explore the experiences of three subgroups of patients who subsequently: 1) declined participation in the QL; 2) were unreachable by the QL; or 3) were enrolled in or had completed the QL program. Analysis was guided by a phenomenological approach designed to identify emergent themes.

RESULTS

Reasons for QL program non-completion included changing life circumstances and events making cessation unviable; misunderstandings about the QL; discomfort with telephonic counseling; perceived lack of time for counseling; cell phone barriers; and having already quit smoking. We found that some individuals who were no longer engaged with the QL still desired continued support from the QL.

CONCLUSIONS

Participants intentionally and unintentionally disengage from the QL for a wide variety of reasons, several of which are mediated by low socioeconomic status. Integrating QL care with community-based resources that address these mediators could be a promising strategy.

National trends and state-level variation in the duration of incoming quitline calls to 1-800-QUIT-NOW during 2012–2015

Introduction

The duration of incoming quitline calls may serve as a crude proxy for the potential amount of reactive counseling provided.

Aims

To explore whether call duration may be useful for monitoring quitline capacity and service delivery.

Methods

Using data on the duration of incoming quitline calls to 1-800-QUIT-NOW from 2012 through 2015, we examined national trends and state-level variation in average call duration. We estimated a regression model of average call duration as a function of total incoming calls, nationally and by state, controlling for confounders.

Results

From 2012 through 2015, average call duration was 11.4 min, nationally, and was 10 min or longer in 33 states. Average call duration was significantly correlated with quitline service provider. Higher incoming call volume was significantly associated with lower average call duration in 32 states and higher average call duration in five states (P-value <0.05). The relationship between call volume and call duration was not correlated with quitline service provider.

Conclusions

Variation in average call duration across states likely reflects different service delivery models. Average call duration was associated with call volume in many states. Significant changes in call duration may highlight potential quitline capacity issues that warrant further investigation.

Support person interventions to increase use of quitline services among racially diverse low-income smokers: A pilot study

INTRODUCTION

Social support from nonsmokers may have a role in prompting smokers to use evidence-based cessation treatment. Prior studies found that an intervention for nonsmoking support persons (SPs) was effective for promoting smokers' use of free, state quitline services. This pilot study adapted and assessed feasibility of this intervention for a racially diverse, low-income population.

METHODS

Single group, non-randomized design enrolling SP-smoker dyads with low income status enrolled in one of three study "waves" of 10 pairs each. Participants were recruited using flyers and in-person outreach methods. The SP intervention included a 1-session coaching call and written materials; study waves 2 and 3 also included text messaging and a monetary incentive for smokers who used quitline services. Using content analysis, the intervention was iteratively adapted based on SP feedback. Baseline measures assessed socio-demographics, dyad and tobacco use characteristics. Follow-up assessments were conducted among SPs at 1-month follow-up and among smokers at 3-months follow-up. Feasibility indicators were recruitment, retention, and SP intervention acceptability and adherence. Secondary outcomes were smokers' use of any quitline service verified by quitline staff and 7-day, point prevalence, biochemically verified smoking abstinence at 3 months.

RESULTS

Recruitment of 30 dyads was feasible; in-person recruitment methods were the most successful. SPs who completed follow-up assessments found the intervention acceptable, suggesting only minor content modifications, and they perceived the quitline information as novel. But the study had some feasibility challenges (e.g., SP coaching call completion: 60% and SP study retention: 53%). At 3 months, 2 smokers (7%) had used any quitline service and 13% were biochemically confirmed smoking abstinent.

CONCLUSIONS

This pilot study demonstrated feasibility of recruiting SP-smoker dyads from diverse, low-income communities. While the intervention was well received, its delivery was not feasible in this population. Results suggest that further consumer adaptation of the intervention is needed among both SPs and smokers.

Specialized tobacco quitline and basic needs navigation interventions to increase cessation among low income smokers: Study protocol for a randomized controlled trial

Smoking in the United States follows a clear socioeconomic gradient: low-income Americans smoke more and quit less than those with more education and income. Evidence-based interventions like tobacco quitlines are designed to make effective cessation services available on a population basis to all smokers. However, these interventions do not address many of the unique challenges faced by low-income smokers, including unmet basic needs like food, housing, personal safety and money for necessities that often supersede health needs. Research is needed to maximize the use and effectiveness of tobacco quitlines in low-income populations. This paper details the rationale, design and methods for a 2 × 2 randomized controlled trial currently underway comparing the effects of Standard and Specialized Tobacco Quitlines with and without Basic Needs Navigation on intervention engagement and smoking cessation among low-income smokers. Smokers are recruited from United Way 2-1-1 in Missouri and all participants receive tobacco quitline services from Optum. Quitline and navigation services are provided for 3 months. Participants complete telephone surveys at baseline, 3- and 6-month follow up. The primary study outcome is self-reported 7-day point prevalence abstinence at 6-month follow up. Embedding the study in practice agencies will accelerate dissemination and scalability should our findings demonstrate intervention effectiveness.

Quitline treatment dose predicts cessation outcomes among safety net patients linked with treatment via Ask-Advise-Connect

The efficacy of tobacco treatment delivered by state quitlines in diverse populations is well-supported, yet little is known about associations between treatment dose and cessation outcomes following the implementation of Ask-Advise-Connect (AAC), an electronic health record-based systematic referral process that generates a high volume of proactive calls from the state quitline to smokers. The current study is a secondary analysis of a 34-month implementation trial evaluating ACC in 13 safety-net clinics in Houston, TX. Treatment was delivered by a quitline and comprised up to five proactive, telephone-delivered multi-component cognitive-behavioral treatment sessions. Associations between treatment dose and abstinence were examined. Abstinence was assessed by phone six months after treatment enrollment, and biochemically confirmed via mailed saliva cotinine. Among smokers who enrolled in treatment and agreed to follow-up (n = 3704), 29.2% completed no treatment sessions, 35.5% completed one session, 16.4% completed two sessions, and 19.0% completed ≥three sessions. Those who completed one (vs. no) sessions were no more likely to report abstinence (OR: 0.98). Those who completed two (vs. no) sessions were nearly twice as likely to report abstinence (OR: 1.83). Those who completed ≥three (vs. no) sessions were nearly four times as likely to report abstinence (OR: 3.70). Biochemically-confirmed cessation outcomes were similar. Most smokers received minimal or no treatment, and treatment dose had a large impact on abstinence. Results highlight the importance of improving engagement in evidence-based treatment protocols following enrollment. Given that motivation to quit fluctuates, systematically offering enrollment to all smokers at all visits is important.

•

The majority of smokers received minimal or no evidence-based tobacco treatment.

•

Smokers who completed 0 or 1 treatment sessions were unlikely to achieve abstinence.

•

Completion of 2 calls doubled the likelihood of abstinence at 6 months.

•

Completion of ≥3 calls was associated with a near quadrupling of abstinence rates.

•

Improving engagement in evidence-based treatment protocols is a research priority.

Addressing Tobacco Cessation at Federally Qualified Health Centers: Current Practices & Resources

This study assesses the current practices of Federally Qualified Health Centers (FQHCs) to address tobacco cessation with patients. A national sample of 112 FQHC medical directors completed the web-based survey. Frequently endorsed barriers to providing tobacco cessation services were: patients lacking insurance coverage (35%), limited transportation (27%), and variance in coverage of cessation services by insurance type (26%). Nearly 50% indicated that two or more tobacco cessation resources met the needs of their patients; 25% had one resource, and the remaining 25% had no resources. There were no differences among resource groups in the use of electronic health record (EHR) best-practice-alerts for tobacco use or in the perceived barriers to providing tobacco cessation assistance. Systems changes to harmonize coverage of tobacco assistance, such as broader accessibility to evidence-based cessation services could have a positive impact on the efforts of FQHCs to provide tobacco cessation assistance to their patients.

Predictors of engagement in post-discharge quitline counseling among hospitalized smokers

Quitlines provide evidence-based tobacco treatment and multiple calls yield higher quit rates. This study aimed to identify subgroups of smokers with greater quitline engagement following referral during hospitalization. Data were from a randomized clinical trial assessing the effectiveness of fax referral (referral faxed to proactive quitline) versus warm handoff (patient connected to quitline at bedside) (n = 1054). Classification and regression trees analyses evaluated individual and treatment/health system-related variables and their interactions. Among all participants, warm handoff, higher ratings of the tobacco treatment care transition, and being older predicted completing more quitline calls. Among patients enrolled in the quitline, higher transition of care ratings, being older, and use of cessation medication post-discharge predicted completing more calls. Three of the four factors influencing engagement were characteristics of treatment within the hospital (quality of tobacco treatment care transition and referral method) and therapy (use of cessation medications), suggesting potential targets to increase quitline engagement post-discharge.

Simultaneous vs. sequential treatment for smoking and weight management in tobacco quitlines: 6 and 12 month outcomes from a randomized trial

BACKGROUND

Smoking cessation often results in weight gain which discourages many smokers from quitting and can increase health risks. Treatments to reduce cessation-related weight gain have been tested in highly controlled trials of in-person treatment, but have never been tested in a real-world setting, which has inhibited dissemination.

METHODS

The Best Quit Study (BQS) is a replication and "real world" translation using telephone delivery of a prior in-person efficacy trial.

DESIGN

randomized control trial in a quitline setting. Eligible smokers (n = 2540) were randomized to the standard 5-call quitline intervention or quitline plus simultaneous or sequential weight management. Regression analyses tested effectiveness of treatments on self-reported smoking abstinence and weight change at 6 and 12 months.

RESULTS

Study enrollees were from 10 commercial employer groups and three state quitlines. Participants were between ages 18-72, 65.8% female, 68.2% white; 23.0% Medicaid-insured, and 76.3% overweight/obese. The follow-up response rate was lower in the simultaneous group than the control group at 6 months (p = 0.01). While a completers analysis of 30-day point prevalence abstinence detected no differences among groups at 6 or 12 months, multiply imputed abstinence showed quit rate differences at 6 months for:simultaneous (40.3%) vs. sequential (48.3%), p = 0.034 and simultaneous vs. control (44.9%), p = 0.043. At 12 months, multiply imputed abstinence, was significantly lower for the simultaneous group (40.7%) vs. control (46.0%), p < 0.05 and vs. sequential (46.3%), p < 0.05. Weight gain at 6 and 12 months was minimal and not different among treatment groups. The sequential group completed fewer total calls (3.75) vs. control (4.16) and vs. simultaneous group (3.83), p = 0.01, and fewer weight calls (0.94) than simultaneous (2.33), p < 0.0001. The number of calls completed predicted 30-day abstinence, p < 0.001, but not weight outcomes.

DISCUSSION

This study offers a model for evaluating population-level public health interventions conducted in partnership with tobacco quitlines.

CONCLUSIONS

Simultaneous (vs. sequential) delivery of phone/web weight management with cessation treatment in the quitline setting may adversely affect quit rate. Neither a simultaneous nor sequential approach to addressing weight produced any benefit on suppressing weight gain. This study highlights the need and the challenges of testing intensive interventions in real-world settings.

Tobacco dependence treatment in the emergency department: A randomized trial using the Multiphase Optimization Strategy

BACKGROUND

Tobacco dependence remains the leading preventable cause of death in the developed world. Smokers are disproportionately from lower socioeconomic groups, and may use the hospital emergency department (ED) as an important source of care. A recent clinical trial demonstrated the efficacy of a multicomponent intervention to help smokers quit, but the independent contributions of those components is unknown.

METHODS

This is a full-factorial (16-arm) randomized trial in a busy hospital ED of 4 tobacco dependence interventions: brief motivational interviewing, nicotine replacement therapy, referral to a telephone quitline, and a texting program. The trial utilizes the Multiphase Optimization Strategy (MOST) and a novel mixed methods analytic design to assess clinical efficacy, cost effectiveness, and qualitative participant feedback. The primary endpoint is tobacco abstinence at 3months, verified by participants' exhaled carbon monoxide.

RESULTS

Study enrollment began in February 2017. As of April 2017, 52 of 1056 planned participants (4.9%) were enrolled. Telephone-based semi-structured participant interviews and in-person biochemical verification of smoking abstinence are completed at the 3-month follow-up. Efficacy and cost effectiveness analyses will be conducted after follow-up is completed.

DISCUSSION

The goal of this study is to identify a clinically efficacious, cost-effective intervention package for the initial treatment of tobacco dependence in ED patients. The efficacy of this combination can then be tested in a subsequent confirmatory trial. Our approach incorporates qualitative feedback from study participants in evaluating which intervention components will be tested in the future trial.

Motivational Benefits of Social Support and Behavioural Interventions for Smoking Cessation

This study examined the role of social support and behavioral interventions used during the last unsuccessful quit attempt for smokers' intentions to quit smoking within the next 6 months, and identified smokers' attributes associated with use of social support and behavioral interventions. The analytic sample included 7,195 adult daily smokers who responded to the 2010-2011 Tobacco Use Supplement to the Current Population Survey, conducted in the US, and indicated having a serious quit attempt in the past 12 months. Smokers who relied on social support from friends and family had higher odds of intending to quit than those who did not (OR= 1.39, 95% CI= 1.22:1.58), and smokers who used interventions had higher odds of intending to quit than those who did not (OR= 1.36, 95% CI= 1.07:1.74). These associations were similar for both sexes, all age groups, and nicotine dependence levels. Both, relying on social support and use of behavioral interventions were more common among smokers who were female, higher educated, residing in the Western US region, and those who used pharmacological aids for smoking cessation. Social support and behavioral interventions are associated with higher intentions to quit among attempters who relapsed and thus, may aid future smoking cessation.
