A randomized trial of a brief intervention to promote smoking cessation for parents during child hospitalization

Cigarette smoke exposure of hospitalised children: Prevalence of smoking in parents or carers and admission practices of health services

AIM

The aim of this study is to understand the exposure to second-hand tobacco smoke in the homes of hospitalised children through: (i) understanding the prevalence of smoking in adults or carers and (ii) examining the health services' approach to identifying parental smoking status.

METHODS

This prospective observational study consisted of two surveys: one administered to parents/carers of hospitalised children and one to health services. The first cross-sectional survey aimed to elicit the proportion of children requiring admission to a regional Victorian general paediatric unit who live with adults who smoke cigarettes. The survey was delivered to participating parents/carers during the standard nursing admission process. The second survey was administered across 15 public health services to determine if identification of parent/carer's smoking status is a routine part of their standard paediatric admission practice.

RESULTS

For the parental survey, 453 responses were obtained from 782 consecutive new admissions. Nearly a third (n = 136, 30%) requiring hospital admission were found to be living with at least one parent/carer who identified as a current cigarette smoker. Of the 15 health services surveyed, only four (27%) nursing units reported routinely asking parents/carers about their smoking status as part of their standard admission process.

CONCLUSION

Admission to hospital provides an opportunity to enhance care for children by addressing nicotine dependence within their families. Findings suggest routine recording of smoking status can be improved, to drive smoking cessation and brief intervention conversations with parents and carers of children admitted to hospital.

Intervening With Smoking Parents of Inpatients to Reduce Exposure: The INSPIRE Randomized Controlled Trial

BACKGROUND

Hospitalized children have high rates of tobacco smoke exposure; parents who smoke may be receptive to interventions during their child's hospitalization.

OBJECTIVE

We tested the efficacy of a smoking cessation intervention for parents of hospitalized children.

METHODS

We conducted a randomized, single-blind clinical trial from 12/14-5/18 at the Children's Hospital Colorado. Hospitalized children who had a parent who smoked tobacco were eligible.

INTERVENTION

Intervention participants received motivational interviewing sessions, 2 weeks of nicotine replacement therapy; both groups received referral to the Quitline Consenting parents completed a questionnaire; urine was collected from the child for measurement of cotinine. Our primary outcome was: 1) increase in reporting "no one is allowed to smoke anywhere" in the home (smoke-free home rule). Additional outcomes included: 2) change in child's cotinine from baseline to 1 year, and 3) parental quitting at 1 year. Data were analyzed using Chi-square and t tests for bivariable data, and multivariable logistic and linear regression.

RESULTS

Of 1641 eligible families approached, 252 were randomized (15%); 149 families had follow-up data at 12 months (59%). In the adjusted analysis, there was no difference between the groups in smoke free home rules, or child cotinine level; in an intention-to-treat analysis, 15% in the intervention group versus 8% of controls reported quit (p=0.07).

CONCLUSIONS

A smoking cessation intervention can be delivered to parents of hospitalized children. While hospitalization provides an opportunity to help parents quit smoking, more efficient and effective engagement strategies are needed to optimize tobacco control success.

Barriers and Motivators for Smoking Cessation Among Caregivers of Inpatient Pediatric Patients

OBJECTIVE

To examine perceived barriers and motivators for smoking cessation among caregivers of inpatient pediatric patients.

METHODS

From December 2014 to June 2018, trained tobacco counselors conducted motivational interviews (MI) with caregivers of inpatient pediatric patients ages 0 to 17, who participated in the intervention arm of a smoking cessation randomized controlled trial. By using NVivo 12 software, the first MI session with each caregiver was evaluated by 3 individuals to identify and categorize motivators and barriers; agreement among reviewers was reached. Barriers and motivators were examined in bivariable analysis with χ2 or Fisher's exact tests for categorical factors and with t-tests for continuous factors by using SAS 9.4 software.

RESULTS

Of the 124 caregivers randomized to intervention, 99 subjects (80%) completed ≥1 MI sessions. The most prevalent barriers to cessation were stress (57%) and social influence (37%).The most prevalent motivators were desire to lead a healthy life (54%) and desire to improve the child and family's well-being (47%). Older parent age was associated with wanting to lead a healthy life, and younger child age was associated with wanting to improve the child and family's well-being.

CONCLUSIONS

Understanding barriers and motivators to cessation among caregivers is crucial in reducing pediatric secondhand smoke (SHS). When developing caregiver cessation programs in an inpatient clinic encounter, caregiver barriers and motivators may help in targeting education and strategies to help counselors and clinicians better identify and support caregivers who wish to quit smoking.

Quality Improvement Approach to Increase Inpatient Pediatric Secondhand Smoke Exposure Screening

BACKGROUND

Secondhand smoke exposure (SHSe) is highly prevalent among children and has numerous adverse health effects. Consistent screening for SHSe is an essential first step to helping families break the toxic cycle of smoking.

METHODS

With this quality improvement project, we evaluated a SHSe screening and cessation resource distribution protocol in a general pediatrics inpatient unit of a safety-net hospital. Our primary outcome measure was the percent of admissions screened for SHSe, with a goal of increasing our documented rate of SHSe screening from 0% to 70% within 6 months of implementation. Our secondary outcome measure was the percent of those who screened positive for SHSe who were offered smoking cessation resources. Process measures included tracking nurse confidence in screening and compliance with new workflow training. Balancing measures were nurse satisfaction and brevity of screening.

RESULTS

From May 1, 2019, to April 30, 2020, nurses screened 97.2% of the 394 patients admitted to the pediatric unit for SHSe. Of the patients screened, 15.7% were exposed to cigarettes or other tobacco products, 5.6% to e-cigarettes, and 6.5% to marijuana. Nurses documented offering "Quit Kits" with cessation materials to 45 caregivers (72.6% of positive screen results) and offering 33 referrals to the California Smokers' Helpline (53.2% of positive screen results).

CONCLUSION

In this project, we successfully implemented a screening protocol for SHSe to tobacco, e-cigarettes, and marijuana and a workflow for cessation resource distribution in an inpatient pediatric setting that far exceeded goals. Requiring minimal maintenance and using just a simple paper-based format, the workflow could be adopted at other institutions.

Hard to Reach or Just Not Enough? A Narrative Review of Inpatient Tobacco Cessation Programs in Pediatrics

Caregiver smoking is a significant risk factor for children with acute and chronic diseases. Hospitalization presents an opportunity to explore caregiver smoking as a modifiable risk factor during a time of crisis when the motivation to change could be heightened. To date, there has not been a published review on inpatient smoking cessation interventions in pediatrics that focus on supporting caregivers of hospitalized children. The goals of this review were to identify and assess the reach and efficacy of tobacco cessation strategies implemented across inpatient units in pediatrics and mother-baby units. This review also proposes clinical and research implications along with program-building recommendations that can help inform future practice in tobacco cessation. A narrative review of the literature identified 14 peer-reviewed studies that described smoking cessation interventions between 2002 and 2021. There were five randomized controlled trials, seven prospective studies, and one retrospective study. The primary kinds of interventions were counseling to heighten caregiver contemplation to quit (n = 12), provision of Nicotine Replacement Therapy (NRT) medications (n = 7), and follow-up with the local Quitline (n = 12). A diverse range of deliverers implemented interventions across studies. Variation in defining quit attempts along with tobacco reduction and cessation outcomes contributed to mixed findings across studies.

A Randomized Controlled Trial for Parents of Hospitalized Children: Keeping Kids Safe From Guns

OBJECTIVES

To assess an educational intervention (BeSMART) for parents of hospitalized children on behaviors, beliefs, and knowledge about firearm safety.

METHODS

A randomized controlled, 3-arm preintervention and postintervention study compared BeSMART video and handout interventions (with and without physician review) to tobacco smoke videos and handouts (control) on parental behaviors, beliefs, and knowledge. Eligibility criteria included parents and/or guardians residing with hospitalized children aged <20 years. The primary outcome was a change in parent-reported frequency of asking about guns in homes visited by their children preintervention to 1 month after intervention. Secondary outcomes were parent-reported likelihood of asking about guns in others' homes immediately postintervention and change in firearm safety beliefs and/or knowledge in the intervention versus control group, analyzed with analysis of variance. McNemar's and paired t tests compared changes within groups, and generalized estimating equations compared change between groups for the primary outcome.

RESULTS

A total of 225 participants enrolled. Both intervention and control groups revealed significant increase mean in parent-reported Likert score of frequency of asking about guns within groups preintervention to 1 month after intervention (BeSMART: 1.5 to 2.3, P = .04; BeSMART + physician review: 1.4 to 1.9, P = .03; control: 1.4 to 2.3, P = .01). Change between groups was not significant (P = .81). Immediately postintervention, intervention groups reported higher likelihood of asking about guns (P < .001). Study groups revealed no significant differences in beliefs. Firearm safety knowledge increased significantly in the intervention groups.

CONCLUSIONS

BeSMART firearm injury prevention intervention in a hospital setting increased parental knowledge regarding firearm safety. Immediately postintervention, BeSMART groups reported higher likelihood of asking about guns in others' homes compared with controls. At 1 month after intervention, all groups reported increased frequency asking about guns. Future investigations are needed to understand the duration of intervention impact.

Prevalence and Quantification of Secondhand Smoke Exposure Among Hospitalized Children <6 Years of Age

OBJECTIVES

Using caregiver report and urinary cotinine measures, we defined the prevalence of secondhand smoke (SHS) exposure among young, hospitalized children and compared exposure among those hospitalized with pneumonia versus those with acute, nonrespiratory illnesses.

METHODS

Children aged <6 years hospitalized with pneumonia or acute, nonrespiratory illnesses were enrolled on admission, and urinary cotinine, a nicotine biomarker, was measured. Caregivers were also queried on home SHS exposure. We modeled associations between sociodemographic characteristics and exposure intensity on the basis of cotinine level (none, light, and heavy) using multivariable proportional odds regression. We also examined associations between SHS exposure intensity and diagnosis (pneumonia versus nonrespiratory illness). For this analysis, diagnosis was the outcome of interest, and urinary cotinine was the primary exposure variable.

RESULTS

Overall, 36% of the 239 enrolled children had reported home SHS exposure, although 77% had detectable levels of urinary cotinine, including 59% with heavy exposure. The highest urinary cotinine level was among children exposed to indoor smoking (7.78 ng/mL, interquartile range 2.93-18.65; P < .001). Increased SHS exposure was associated with non-Hispanic ethnicity, lower household educational attainment, and public insurance. There were no differences in SHS exposure by diagnosis.

CONCLUSIONS

Among hospitalized young children, reported home SHS exposure was common but substantially underestimated when compared with urinary cotinine levels. The highest urinary cotinine levels were among children exposed to indoor smoking. Future public health interventions, as well as more robust SHS exposure screenings on hospital admission, are needed to reduce the prevalence of SHS exposure among young children.

Smoking Behaviors Among Tobacco-Using Parents of Hospitalized Children and Association With Child Cotinine Level

OBJECTIVES

Understanding patterns of parental tobacco use and their association with child exposure can help us target interventions more appropriately. We aimed to examine the association between parental smoking practices and cotinine levels of hospitalized children.

METHODS

This is a secondary analysis of data collected from parents of hospitalized children, recruited for a cessation intervention randomized controlled trial. Smoking parents were identified by using a medical record screening question. Parent-reported demographics and smoking habits were compared to child urine cotinine by using geometric means and log-transformed cotinine levels in multivariable linear regression analyses.

RESULTS

A total of 213 patients had complete baseline parent-interview and urine cotinine data. The median age was 4 (interquartile range: 1-9); 57% were boys; 56% were white, 12% were Black, and 23% were multiracial; 36% identified as Hispanic. Most families (54%) had 1 smoker in the home; 36% had 2, and 9% had ≥3. Many (77%) reported having a ban on smoking in the home, and 86% reported smoking only outside. The geometric mean cotinine level of the cohort was 0.98 ng/mL. Higher cotinine levels were associated with more smokers in the home (ratio of 2.99) and smoking inside the house (ratio of 4.11).

CONCLUSIONS

Having more smokers in the home and parents who smoke inside are associated with increased smoke exposure; however, even children whose families who smoke only outside the home have significant levels of cotinine, a marker for toxin exposure.

The Effectiveness of Smoking Cessation Interventions Tailored to Smoking Parents of Children Aged 0–18 Years: A Meta-Analysis

INTRODUCTION

A meta-analysis was conducted to examine the effectiveness of smoking cessation interventions tailored to parents of children aged 0-18 years.

METHODS

A systematic search was carried out in PsycInfo, Embase, and PubMed in March 2020. A manual search of the reference lists of the included studies and systematic reviews related to the topic was also performed. Two authors independently screened the studies based on the following inclusion criteria: (1) effect studies with control groups that examine smoking cessation interventions tailored to parents of children (0-18 years), and (2) full-text original articles written in English and published between January 1990 and February 2020. In total, 18 studies were included in the analyses. The TiDieR checklist and the Cochrane Risk of Bias Tool 2.0 were used to extract data and to assess the risk of bias. Consensus among authors was reached at each stage.

RESULTS

Random-effects meta-analyses were performed. With a total number of 8,560 parents, the pooled relative risk was 1.62 (95% CI 1.38-1.90; p < 0.00001), showing a modest effect of the interventions on smoking cessation. Overall, 13.1% of the parents in the intervention conditions reported abstinence versus 8.4% of the parents in the control conditions.

DISCUSSION/CONCLUSION

Smoking cessation interventions tailored to parents are modestly effective. To increase the effectiveness and the impact of these interventions in terms of controlling tobacco use and public health, it is crucial for further research to explore how these interventions can be improved.

Electronic Health Record Classification of Tobacco Smoke Exposure and Cotinine Levels in Hospitalized Pediatric Patients

OBJECTIVES

Documentation of children's tobacco smoke exposure (TSE) in the electronic health record (EHR) can have important implications for clinical care. However, it may not be accurate if it is not based on biochemical assessment, the most reliable method of verifying TSE. Our objectives were to compare the accuracy of EHR classification of TSE with cotinine verification and to explore parent and child variables associated with biochemically verified TSE.

METHODS

Participants were 171 hospitalized pediatric patients (ages 0-17 years; mean age 5.1 [SD 3.7] years) who had EHR documentation of TSE and measured salivary cotinine. Children with cotinine levels >1 ng/mL were classified as having biochemical verification of TSE. Parents reported sociodemographic characteristics, and children's EHRs were abstracted for TSE status, past medical history, and diagnoses. We conducted χ² tests to assess the agreement between EHR classification of TSE status and cotinine levels. Then, we assessed the relationship between sociodemographic and clinical variables and cotinine using crude and adjusted logistic regression models.

RESULTS

Overall, 71% (121 of 171) of EHR classifications were correct on the basis of cotinine levels. Specificity analyses showed that 77% (53 of 69) were correctly identified as exposed to tobacco smoke. Sensitivity analyses showed that 67% (68 of 102) were correctly identified as unexposed. The negative predictive value was 0.61 (53 of 87); 39% (34 of 87) were misclassified as unexposed. The positive predictive value was 0.81 (68 of 84); 19% (16 of 84) were misclassified as exposed.

CONCLUSIONS

Almost 40% of children were misclassified in the EHR as unexposed to tobacco smoke. Biochemical verification should be used as part of universal TSE screening during pediatric hospitalizations.

Proactive Telephone Smoking Cessation Counseling Tailored to Parents: Results of a Randomized Controlled Effectiveness Trial

A recent Dutch efficacy trial showed the efficacy of a telephone smoking cessation counseling tailored to smoking parents. Currently, it is unknown whether such telephone counseling would be effective under more real-world conditions. This study aimed to examine the effectiveness of parent-tailored telephone smoking cessation counseling in a two-arm randomized controlled effectiveness trial and whether the effectiveness depended on the recruitment approaches that were used to recruit parents (mass media vs. health care). In total, 87 parents received either telephone counseling (intervention) or a self-help brochure (control). Parents were asked to complete questionnaires at baseline and three months post-intervention. Results showed that the odds of reporting 7-day point-prevalence abstinence at three months post-intervention was 7.54 higher for parents who received telephone counseling than for parents in the control condition (53.3% vs. 13.2%, 95% CI = 2.49–22.84). Because inclusion was lower than anticipated, interaction-effects of condition and recruitment approach could not be interpreted. The present study demonstrates that the parent-tailored smoking cessation telephone counseling is effective in helping parents to quit smoking. Yet, before large-scale implementation, future research should focus on how recruitment of parents via the recruitment approaches could be improved.

Family and carer smoking control programmes for reducing children's exposure to environmental tobacco smoke

BACKGROUND

Children's exposure to other people's tobacco smoke (environmental tobacco smoke, or ETS) is associated with a range of adverse health outcomes for children. Parental smoking is a common source of children's exposure to ETS. Older children in child care or educational settings are also at risk of exposure to ETS. Preventing exposure to ETS during infancy and childhood has significant potential to improve children's health worldwide.

OBJECTIVES

To determine the effectiveness of interventions designed to reduce exposure of children to environmental tobacco smoke, or ETS.

SEARCH METHODS

We searched the Cochrane Tobacco Addiction Group Specialised Register and conducted additional searches of the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, PsycINFO, Embase, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), the Education Resource Information Center (ERIC), and the Social Science Citation Index & Science Citation Index (Web of Knowledge). We conducted the most recent search in February 2017.

SELECTION CRITERIA

We included controlled trials, with or without random allocation, that enrolled participants (parents and other family members, child care workers, and teachers) involved in the care and education of infants and young children (from birth to 12 years of age). All mechanisms for reducing children's ETS exposure were eligible, including smoking prevention, cessation, and control programmes. These include health promotion, social-behavioural therapies, technology, education, and clinical interventions.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed studies and extracted data. Due to heterogeneity of methods and outcome measures, we did not pool results but instead synthesised study findings narratively.

MAIN RESULTS

Seventy-eight studies met the inclusion criteria, and we assessed all evidence to be of low or very low quality based on GRADE assessment. We judged nine studies to be at low risk of bias, 35 to have unclear overall risk of bias, and 34 to have high risk of bias. Twenty-one interventions targeted populations or community settings, 27 studies were conducted in the well-child healthcare setting and 26 in the ill-child healthcare setting. Two further studies conducted in paediatric clinics did not make clear whether visits were made to well- or ill-children, and another included visits to both well- and ill-children. Forty-five studies were reported from North America, 22 from other high-income countries, and 11 from low- or middle-income countries. Only 26 of the 78 studies reported a beneficial intervention effect for reduction of child ETS exposure, 24 of which were statistically significant. Of these 24 studies, 13 used objective measures of children's ETS exposure. We were unable to pinpoint what made these programmes effective. Studies showing a significant effect used a range of interventions: nine used in-person counselling or motivational interviewing; another study used telephone counselling, and one used a combination of in-person and telephone counselling; three used multi-component counselling-based interventions; two used multi-component education-based interventions; one used a school-based strategy; four used educational interventions, including one that used picture books; one used a smoking cessation intervention; one used a brief intervention; and another did not describe the intervention. Of the 52 studies that did not show a significant reduction in child ETS exposure, 19 used more intensive counselling approaches, including motivational interviewing, education, coaching, and smoking cessation brief advice. Other interventions consisted of brief advice or counselling (10 studies), feedback of a biological measure of children's ETS exposure (six studies), nicotine replacement therapy (two studies), feedback of maternal cotinine (one study), computerised risk assessment (one study), telephone smoking cessation support (two studies), educational home visits (eight studies), group sessions (one study), educational materials (three studies), and school-based policy and health promotion (one study). Some studies employed more than one intervention. 35 of the 78 studies reported a reduction in ETS exposure for children, irrespective of assignment to intervention and comparison groups. One study did not aim to reduce children's tobacco smoke exposure but rather sought to reduce symptoms of asthma, and found a significant reduction in symptoms among the group exposed to motivational interviewing. We found little evidence of difference in effectiveness of interventions between the well infant, child respiratory illness, and other child illness settings as contexts for parental smoking cessation interventions.

AUTHORS' CONCLUSIONS

A minority of interventions have been shown to reduce children's exposure to environmental tobacco smoke and improve children's health, but the features that differentiate the effective interventions from those without clear evidence of effectiveness remain unclear. The evidence was judged to be of low or very low quality, as many of the trials are at a high risk of bias, are small and inadequately powered, with heterogeneous interventions and populations.

Secondhand Smoke Exposure and Pediatric Healthcare Visits and Hospitalizations

INTRODUCTION

This study assessed the relationship between secondhand smoke exposure (SHSe) as measured by serum cotinine and healthcare utilization among children.

METHODS

In 2016, the 2009-2012 National Health and Nutrition Examination Survey data were analyzed including 4,985 children aged 3-19 years. Associations between SHSe and having a routine place for healthcare, type of place, and hospital utilization were examined using logistic regression models. Poisson regression analyses assessed the relationship between SHSe and number of hospital admissions. Relationships between SHSe and acute care visits and hospital utilization were examined among asthmatic children.

RESULTS

SHSe level did not differ by having a routine place for healthcare, although children with high SHSe indicative of active smoking (cotinine ≥3 ng/mL) were 3.49 times (95% CI=1.77, 6.89) more likely to use an emergency department. Children with high SHSe were 2.85 times (95% CI=1.87, 4.34) more likely to have had an overnight hospital stay. Children with high SHSe had 2.05 times (95% CI=1.46, 2.87) the risk of having a higher number of hospital admissions for overnight stays versus children with no SHSe (cotinine <0.05 ng/mL). Among asthmatic children, those with high SHSe and low SHSe (cotinine 0.05-2.99 ng/mL) were more likely to have an acute care visit, overnight hospital stay, and higher number of hospital admissions than asthmatic children with no SHSe.

CONCLUSIONS

High SHSe is associated with increased healthcare utilization. The emergency department and inpatient settings are important venues in which to routinely offer cessation and SHSe reduction interventions.

Pediatric Firearm-Related Injuries in the United States

Pediatric firearm-related deaths and injuries are a national public health crisis. In this Special Review Article, we characterize the epidemiology of firearm-related injuries in the United States and discuss public health programs, the role of pediatricians, and legislative efforts to address this health crisis. Firearm-related injuries are leading causes of unintentional injury deaths in children and adolescents. Children are more likely to be victims of unintentional injuries, the majority of which occur in the home, and adolescents are more likely to suffer from intentional injuries due to either assault or suicide attempts. Guns are present in 18% to 64% of US households, with significant variability by geographic region. Almost 40% of parents erroneously believe their children are unaware of the storage location of household guns, and 22% of parents wrongly believe that their children have never handled household guns. Public health interventions to increase firearm safety have demonstrated varying results, but the most effective programs have provided free gun safety devices to families. Pediatricians should continue working to reduce gun violence by asking patients and their families about firearm access, encouraging safe storage, and supporting firearm-related injury prevention research. Pediatricians should also play a role in educating trainees about gun violence. From a legislative perspective, universal background checks have been shown to decrease firearm homicides across all ages, and child safety laws have been shown to decrease unintentional firearm deaths and suicide deaths in youth. A collective, data-driven public health approach is crucial to halt the epidemic of pediatric firearm-related injury.

Motivating parents of kids with asthma to quit smoking: the effect of the teachable moment and increasing intervention intensity using a longitudinal randomized trial design

AIMS

We tested two aims: (1) the teachable moment (TM): whether second-hand smoke exposure (SHSe) feedback motivates cessation in parents of children with asthma versus parents of healthy children (HC); and (2) whether greater intervention intensity [enhanced-precaution adoption model (PAM)] produces greater cessation than a previously tested intervention (PAM).

DESIGN AND INTERVENTIONS

Aim 1: two home visits (asthma education or child wellness), and cessation induction using motivational interviewing and SHSe feedback. Aim 2: post-home-visits, parents with asthmatic children were randomized to PAM (n = 171; six asthma education calls) or enhanced-PAM (n = 170; six asthma education/smoking cessation calls + repeat SHSe feedback).

SETTING

Rhode Island, USA.

PARTICIPANTS

Parents of asthmatic (n = 341) or healthy (n = 219) children who did not have to want to quit smoking to enroll.

MEASUREMENTS

Measurements were given at baseline, 2, 4, 6 and 12 months. Abstinence was bioverified. Outcomes were 7-day and 30-day point prevalence abstinence (ppa) and SHSe (primary) and asthma morbidity (secondary).

FINDINGS

Aim 1: the TM was supported: parents of asthmatic children were more than twice as likely to achieve 30-day [odds ratio (OR) = 2.60, 95% confidence interval (CI) = 1.22-5.54] and 7-day ppa (OR = 2.26, 95% CI = 1.13-4.51) at 2 months (primary end-point) and have non-detectable levels of SHSe than HCs. Greater treatment intensity yielded stronger TM effects (OR = 3.60; 95% CI = 1.72-7.55). Aim 2: enhanced-PAM was more likely to achieve 30-day ppa at the primary end-point, 4 months (OR = 2.12, 95% CI 1.09-4.12) and improved asthma outcomes versus PAM.

CONCLUSIONS

Smoking cessation intervention (Motivational Interviewing plus biomarker feedback) appear to motivate smoking cessation more strongly among parents of asthmatic children than among parents of healthy children. Increased intervention intensity yields greater smoking cessation among parents of asthmatic children and better asthma outcomes.

Implementation of an Inpatient Electronic Referral System (Opt-to-Quit) From the Electronic Health Record to the New York State Smokers' Quitline: First Steps

OBJECTIVES

(1) To implement a new policy-driven referral program, Opt-to-Quit, using electronic data transfer from the electronic health record (EHR) to the New York State Smokers' Quitline (NYSSQL) and (2) to improve referrals to the NYSSQL for smoking caregivers of children admitted to a children's hospital.

METHODS

Smoking caregivers of pediatric patients were referred to the NYSSQL through a standardized template built into the EHR, during the child's hospitalization or emergency department encounter. Direct data exchange was based on a point-to-point protocol, without dependence on any external centralized processing service. Input and oversight were provided by a multidisciplinary task force, which included physician and nursing leadership, information technology specialists, Health Insurance Portability and Accountability Act compliance personnel and legal counsel, and NYSSQL staff. The process was refined through several iterative plan-do-study-act cycles, using a single-armed, prospective cohort study design, including surveys of nursing staff and continued input of information technology experts on both hospital and Quitline sides.

RESULTS

In 2013, 193 smokers were identified in 2 pilot units; 62% (n= 119) accepted referral to the NYSSQL. In 2014, after expansion to all inpatient units and the emergency department, 745 smokers were identified, and 36% (n = 266) accepted referral. Over the 2 years, overall increase in referrals was 124%; as of the first quarter of 2015, referral rate was sustained at 34%.

CONCLUSIONS

Hospital-wide implementation of the Opt-to-Quit program through our EHR was feasible and sustainable and has significantly improved referrals to the NYSSQL.

The art and science of study identification: a comparative analysis of two systematic reviews

BACKGROUND

Systematic reviews (SRs) form the foundation for guidelines and evidence-based policy in medicine and public health. Although similar systematic reviews may include non-identical sets of studies, and it is recognized that different sets of studies may lead to different conclusions, little work has been published on why SR study cohorts differ.

METHODS

We took advantage of concurrent publication of two SRs on the same topic - prevention of child exposure to tobacco smoke - to understand why study cohorts differed in the two reviews. We identified all studies included in just one review, investigated validity of specified reasons for exclusions, and, using database records, explored reasons for study non-identification. We assessed review methods and discordancy, and attempted to assess whether changes in study cohorts would have changed conclusions.

RESULTS

Sixty-one studies were included in the two reviews. Thirty-five studies were present in just one review; of these, twenty were identified and excluded by the parallel review. Omissions were due to: review scope (9 studies, 26%), outcomes of interest not measured (8 studies, 23%), exclusion of reports with inadequate reporting (6 studies, 17%), mixed or unclear reasons (3 studies, 8%), search strategies concerning filters, tagging, and keywords (3 studies, 8%), search strategies regarding sources (PUBMED not searched) (2 studies, 6%); discordant interpretation of same eligibility criteria (2 studies, 6%), and non-identification due to non-specific study topic (2 studies, 6%). Review conclusions differed, but were likely due to differences in synthesis methods, not differences in study cohorts.

CONCLUSIONS

The process of study identification for SRs is part art and part science. While some differences are due to differences in review scope, outcomes measured, or reporting practices, others are caused by search methods or discrepancies in reviewer interpretations. Different study cohorts may or may not be a cause of differing SR results. Completeness of SR study cohorts could be enhanced by 1 - independent identification of studies by at least two reviewers, as recommended by recent guidelines, 2 - searching PUBMED with free-text keywords in addition to MEDLINE to identify recent studies, and 3 - Using validated search filters.

A Brief Inpatient Intervention Using a Short Video to Promote Reduction of Child Tobacco Smoke Exposure

OBJECTIVES

Tobacco smoke exposure (TSE) increases the risk for respiratory-related disease and hospitalizations. The hypothesis of this study was that a brief intervention (which included a motivational video) provided to parents and caregivers during their child's hospitalization would be associated with improved knowledge and behavior changes that may reduce the child's TSE.

METHODS

Parents and caregivers of children hospitalized for respiratory illnesses with TSE were recruited between June and December 2012. They completed a questionnaire to determine baseline knowledge regarding the health effects of smoke exposure. The intervention included a motivational video, written smoking cessation materials, and referral to the state quitline. The questionnaire was repeated after the intervention; telephone follow-up at 1 and 3 months included knowledge questions and assessed behavior changes. Paired t tests were used to compare preintervention and postintervention knowledge scores.

RESULTS

A total of 167 parents/caregivers were enrolled. The mean preintervention knowledge score was high at 5.4 of 6, which improved for 60 parents/caregivers (36%, P < .001) after the intervention and was sustained at follow-up. Follow-up was obtained from 123 (74%) parents/caregivers, and 90% reported behavior changes to reduce TSE. There was a 13% reported quit rate among the 99 parents/caregivers who smoked (95% confidence interval: 7-21). Other behavior changes reported included initiating home and vehicle smoking bans, discussing reduction of the child's smoke exposure, and showing the video to others. Improvement in knowledge after this brief intervention was associated with reported initiation of home and vehicle smoking bans (P < .01).

CONCLUSIONS

Parents and caregivers of smoke-exposed children hospitalized for respiratory illnesses had high baseline knowledge of the effects of TSE. A brief intervention that included a motivational video was associated with reported behavior changes in parents/caretakers that decreased second- and third-hand smoke. Improvement of knowledge was associated with institution of home and vehicle smoking bans.

Family and carer smoking control programmes for reducing children's exposure to environmental tobacco smoke

BACKGROUND

Children's exposure to other people's cigarette smoke (environmental tobacco smoke, or ETS) is associated with a range of adverse health outcomes for children. Parental smoking is a common source of children's exposure to ETS. Older children are also at risk of exposure to ETS in child care or educational settings. Preventing exposure to cigarette smoke in infancy and childhood has significant potential to improve children's health worldwide.

OBJECTIVES

To determine the effectiveness of interventions aiming to reduce exposure of children to ETS.

SEARCH METHODS

We searched the Cochrane Tobacco Addiction Group Specialized Register and conducted additional searches of the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, PsycINFO, EMBASE, CINAHL, ERIC, and The Social Science Citation Index & Science Citation Index (Web of Knowledge). Date of the most recent search: September 2013.

SELECTION CRITERIA

Controlled trials with or without random allocation. Interventions must have addressed participants (parents and other family members, child care workers and teachers) involved with the care and education of infants and young children (aged 0 to 12 years). All mechanisms for reduction of children's ETS exposure, and smoking prevention, cessation, and control programmes were included. These include health promotion, social-behavioural therapies, technology, education, and clinical interventions.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed studies and extracted data. Due to heterogeneity of methodologies and outcome measures, no summary measures were possible and results were synthesised narratively.

MAIN RESULTS

Fifty-seven studies met the inclusion criteria. Seven studies were judged to be at low risk of bias, 27 studies were judged to have unclear overall risk of bias and 23 studies were judged to have high risk of bias. Seven interventions were targeted at populations or community settings, 23 studies were conducted in the 'well child' healthcare setting and 24 in the 'ill child' healthcare setting. Two further studies conducted in paediatric clinics did not make clear whether the visits were to well or ill children, and another included both well and ill child visits. Thirty-six studies were from North America, 14 were in other high income countries and seven studies were from low- or middle-income countries. In only 14 of the 57 studies was there a statistically significant intervention effect for child ETS exposure reduction. Of these 14 studies, six used objective measures of children's ETS exposure. Eight of the studies had a high risk of bias, four had unclear risk of bias and two had a low risk of bias. The studies showing a significant effect used a range of interventions: seven used intensive counselling or motivational interviewing; a further study used telephone counselling; one used a school-based strategy; one used picture books; two used educational home visits; one used brief intervention and one study did not describe the intervention. Of the 42 studies that did not show a significant reduction in child ETS exposure, 14 used more intensive counselling or motivational interviewing, nine used brief advice or counselling, six used feedback of a biological measure of children's ETS exposure, one used feedback of maternal cotinine, two used telephone smoking cessation advice or support, eight used educational home visits, one used group sessions, one used an information kit and letter, one used a booklet and no smoking sign, and one used a school-based policy and health promotion. In 32 of the 57 studies, there was reduction of ETS exposure for children in the study irrespective of assignment to intervention and comparison groups. One study did not aim to reduce children's tobacco smoke exposure, but rather aimed to reduce symptoms of asthma, and found a significant reduction in symptoms in the group exposed to motivational interviewing. We found little evidence of difference in effectiveness of interventions between the well infant, child respiratory illness, and other child illness settings as contexts for parental smoking cessation interventions.

AUTHORS' CONCLUSIONS

While brief counselling interventions have been identified as successful for adults when delivered by physicians, this cannot be extrapolated to adults as parents in child health settings. Although several interventions, including parental education and counselling programmes, have been used to try to reduce children's tobacco smoke exposure, their effectiveness has not been clearly demonstrated. The review was unable to determine if any one intervention reduced parental smoking and child exposure more effectively than others, although seven studies were identified that reported motivational interviewing or intensive counselling provided in clinical settings was effective.
