Admission screening for secondhand tobacco smoke exposure

Quality Improvement Increases Pediatric Community Hospital Smoking Cessation Interventions

BACKGROUND

Tobacco use commonly starts during adolescence and is the leading cause of preventable disease, disability, and death in the United States. Secondhand smoke (SHS) exposure increases asthma and respiratory infection hospitalizations and contributes to sudden unexpected infant death. Few pediatric hospitalist-led smoking cessation studies are formal quality improvement (QI), with most at academic institutions and studying caregivers.

OBJECTIVES

To increase SHS exposure/tobacco use screening, smoking cessation discharge instructions, and Smokers' Helpline referrals for community hospital pediatric patients/caregivers through QI.

METHODS

All pediatric, newborn, and NICU admissions were eligible. The baseline period was December 2019 through November 2020 and intervention period December 2020 through June 2021. Interventions included hospitalist education, standardizing documentation, visual reminders, and Helpline wallet cards. The primary measure was monthly percentage of patients screened for SHS exposure/tobacco use. Secondary measures were percentage of patients/caregivers positive for SHS exposure/tobacco use who received (1) discharge instructions or (2) Helpline referral. Length of stay was a balancing measure. Primary and balancing measures were analyzed with statistical process control. Secondary measures were monitored on run charts.

RESULTS

Average SHS exposure/tobacco use screening rates increased from 14% to 90%, meeting special cause variation beginning December 2020. Median discharge instructions increased from 0% to 56%. Helpline referrals increased from 0% to 17%. Length of stay remained approximately 2 days.

CONCLUSIONS

Pediatrician-led QI can increase SHS exposure/tobacco use screening and interventions in the community hospital setting to encourage smoke exposure reduction and smoking cessation for patients and caregivers.

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.

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.

Smoke Exposure Disclosure: Parental Perspectives of Screening in the Inpatient Setting

OBJECTIVES

Current screening questions for pediatric tobacco smoke exposure are suboptimal. Factors influencing screening accuracy, particularly in the pediatric inpatient setting, are unknown. Our objective was to identify facilitators of and barriers to parental disclosure of smoke exposure when screened during their child's hospitalization and strategies to promote accurate disclosure.

METHODS

This qualitative study was conducted with a convenience sample of parents of children admitted to the medical and surgical unit of a Midwest tertiary care children's hospital. Eligible parents included those with documented disclosure of smoke exposure in the child's electronic health record. A researcher trained in qualitative methods conducted semistructured, in-depth interviews with parents regarding their experiences with smoke exposure screening in the inpatient pediatric setting. Two researchers independently identified concepts directed at barriers, facilitators, and strategies for effective screening, which were compared and reconciled by a third researcher.

RESULTS

Facilitators of disclosing their child's smoke exposure included the following: (1) the caregiver's internal characteristic(s) promoting disclosure, (2) perceived relevance of the screening question to the child's health, and (3) the questioner being viewed positively. Barriers included the following: (1) fear of negative consequences, (2) a vague question, (3) lack of knowledge, (4) guilt, and (5) unconducive environment and timing. The strategies parents suggested to improve screening for smoke exposure included the following: (1) communicate preemptively, (2) provide specific exposure examples, (3) improve questioner-caregiver rapport, and (4) improve screening environment and timing.

CONCLUSIONS

Parents identified various mechanisms to improve tobacco smoke exposure screening. The facilitators, barriers, and strategies provide opportunities to improve the inpatient pediatric screening process.

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.

Smoking Cessation Counseling in the Inpatient Unit: A Survey of Pediatric Hospitalists

OBJECTIVES

To determine practices and beliefs of pediatric hospitalists regarding smoking cessation counseling for caregivers of hospitalized children.

METHODS

An electronic survey was distributed to 249 members of the Pediatric Research in Inpatient Settings Network over 6 weeks in 2017 (83 responses [33%]). Questions explored beliefs regarding the impact of tobacco smoke exposure (TSE) and practices in TSE screening, provision of counseling, resources, and pharmacotherapy. Nonparametric tests were used to compare groups on numeric variables, χ² tests were used to compare groups on nominal variables, and McNemar's test was used to compare dichotomous responses within subjects.

RESULTS

All respondents were familiar with the term "secondhand smoke," and >75% were familiar with "thirdhand smoke" (THS). Familiarity with THS was associated with more recent completion of training (P = .04). Former smokers (7%) were less likely to agree that THS has a significant impact on a child's health (P = .04). Hospitalists ask about TSE more often than they provide counseling, resources, or pharmacotherapy to caregivers who want to quit smoking. Hospitalists are more likely to ask about TSE and provide cessation counseling when patients have asthma as opposed to other diseases. Time was identified by 41% of respondents as a barrier for providing counseling and by 26% of respondents as a barrier for providing resources. Most respondents never prescribe pharmacotherapy (72%), nor do they follow-up with caregivers after hospitalization regarding cessation (87%).

CONCLUSIONS

Although most respondents ask about TSE, opportunities are missed for counseling and providing support to caregivers who want to quit smoking. Providers should be educated about THS, and systems should be streamlined to facilitate brief counseling sessions.

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.

Viruses and non-allergen environmental triggers in asthma

Asthma is a complex inflammatory disease with many triggers. The best understood asthma inflammatory pathways involve signals characterized by peripheral eosinophilia and elevated immunoglobulin E levels (called T2-high or allergic asthma), though other asthma phenotypes exist (eg, T2-low or non-allergic asthma, eosinophilic or neutrophilic-predominant). Common triggers that lead to poor asthma control and exacerbations include respiratory viruses, aeroallergens, house dust, molds, and other organic and inorganic substances. Increasingly recognized non-allergen triggers include tobacco smoke, small particulate matter (eg, PM2.5), and volatile organic compounds. The interaction between respiratory viruses and non-allergen asthma triggers is not well understood, though it is likely a connection exists which may lead to asthma development and/or exacerbations. In this paper we describe common respiratory viruses and non-allergen triggers associated with asthma. In addition, we aim to show the possible interactions, and potential synergy, between viruses and non-allergen triggers. Finally, we introduce a new clinical approach that collects exhaled breath condensates to identify metabolomics associated with viruses and non-allergen triggers that may promote the early management of asthma symptoms.

Improving Screening and Education for Secondhand Smoke Exposure in Primary Care Settings

: Exposure to secondhand smoke (SHS), also known as environmental tobacco smoke, adversely affects human health across the life cycle and has important economic consequences. The fact that many health care providers don't routinely screen all patients for SHS exposure and educate them on the risks associated with it is exacerbated by the lack of any requirement to do so, as well as the absence of adequate SHS screening questions in many electronic health record (EHR) systems. Further research on improving screening and education interventions is therefore warranted. In this quality improvement initiative, we introduced flag reminders, visual reminders, education, and a monetary incentive for providers, which improved their screening for and education on SHS exposure in the patients in a primary care clinic. The clinicians' behavior change in response to these interventions supports our proposal that an effective screening question with a flag reminder be added to the EHR, and confirms the need for continued research on screenings, EHR efficacy, and clinical behavior change.

Tobacco Use Behaviors and Perceptions of Parental Smokers in the Emergency Department Setting

BACKGROUND

More information is needed about modifiable child tobacco smoke exposure (TSE) patterns in racially diverse parental smokers to tailor interventions designed to help parents quit smoking and reduce their child's TSE. Our objectives were to determine whether there were differences in smoking and TSE patterns based on parental race and child age and whether these patterns differed based on child age within black and white parental smokers. Secondary objectives were to assess the relationship between parental perceptions about the effects of smoking and the benefits of quitting on their child based on child age, race, and reported TSE patterns and to examine biochemically verified TSE levels by child age, race, and parent-reported TSE patterns.

METHODS

Participants (N = 415) were non-Hispanic black and non-Hispanic white parental smokers, mean age (standard deviation [SD]) = 31.2 (7.2) years, who visited the Pediatric Emergency Department (PED) or Urgent Care (UC) with their child, mean age (SD) = 4.7 (4.6) years. Parents reported sociodemographics, smoking, and child TSE patterns. We conducted chi-square tests, independent t-tests, and general linear regression models to answer our primary objectives and linear regression models to answer our secondary objectives.

RESULTS

Parents were 56.1% non-Hispanic black; 87.5% women; mean (SD) number of cigarettes smoked/day was 10.5(6.8). A higher proportion of parents with younger children <3 years old reported smoking bans compared with parents with older children ⩾3 to <18 years old (41.3% vs 19.7%, P < .0001). Subsequent analyses revealed this pattern for both black and white parents. A total of 212 (51%) of children had biochemical assessment of TSE; 89.6% had detectable TSE. Younger children had significantly higher cotinine levels than older children independent of their race (P < .001).

CONCLUSIONS

Children of parental smokers who visit the PED/UC were highly tobacco smoke exposed. Both black and white parental smokers with younger children were more likely to enforce smoking bans, but younger children had higher TSE levels than older children. Interventions that target this group of parental smokers with younger children may be more effective than interventions geared to all parental smokers.

Home Smoke Exposure and Health-Related Quality of Life in Children with Acute Respiratory Illness

OBJECTIVE

This study aims to assess whether secondhand smoke (SHS) exposure has an impact on health-related quality of life (HRQOL) in children with acute respiratory illness (ARI).

METHODS

This study was nested within a multicenter, prospective cohort study of children (two weeks to 16 years) with ARI (emergency department visits for croup and hospitalizations for croup, asthma, bronchiolitis, and pneumonia) between July 1, 2014 and June 30, 2016. Subjects were surveyed upon enrollment for sociodemographics, healthcare utilization, home SHS exposure (0 or ≥1 smoker in the home), and child HRQOL (Pediatric Quality of Life Physical Functioning Scale) for both baseline health (preceding illness) and acute illness (on admission). Data on insurance status and medical complexity were collected from the Pediatric Hospital Information System database. Multivariable linear mixed regression models examined associations between SHS exposure and HRQOL.

RESULTS

Home SHS exposure was reported in 728 (32%) of the 2,309 included children. Compared with nonexposed children, SHS-exposed children had significantly lower HRQOL scores for baseline health (mean difference -3.04 [95% CI -4.34, -1.74]) and acute illness (-2.16 [-4.22, -0.10]). Associations were strongest among children living with two or more smokers. HRQOL scores were lower among SHS-exposed children for all four conditions but only significant at baseline for bronchiolitis (-2.94 [-5.0, -0.89]) and pneumonia (-4.13 [-6.82, -1.44]) and on admission for croup (-5.71 [-10.67, -0.75]).

CONCLUSIONS

Our study demonstrates an association between regular SHS exposure and decreased HRQOL with a dose-dependent response for children with ARI, providing further evidence of the negative impact of SHS.

Adolescent Tobacco Smoke Exposure, Respiratory Symptoms, and Emergency Department Use

OBJECTIVES

Our objective was to examine the relationship between distinct tobacco smoke exposure (TSE) measures and TSE-related symptoms and emergency department (ED) and/or urgent care (UC) use among nonsmoking adolescents without asthma diagnoses.

METHODS

We performed a secondary analysis of 7389 adolescents who completed the Population Assessment of Tobacco and Health Study wave 2. Logistic regression and Poisson regression models were built.

RESULTS

Adolescents with TSE were at increased risk of reporting: shortness of breath, finding it hard to exercise, wheezing during or after exercise, and dry cough at night. Adolescents who lived with a smoker and had home TSE were at increased odds of reporting wheezing or whistling in the chest, and only adolescents with home TSE were at increased risk of reporting wheezing that disturbed sleep. Adolescents with TSE were less likely to report very good or excellent overall health and physical health but were more likely to report they sometimes, often, or very often missed school because of illness. Participants who lived with a smoker and had TSE ≥1 hour were more likely to have had an ED and/or UC visit. Participants with any TSE were at increased risk of having a higher number of ED and/or UC visits.

CONCLUSIONS

Different TSE measures uniquely increased the risk of TSE-related symptoms, but any TSE increased the risk of having a higher number of ED and/or UC visits. The providers at these high-volume settings should offer interventions to adolescents who are exposed to tobacco smoke and their families to decrease these symptoms and related morbidity.

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.

Prenatal Versus Postnatal Tobacco Smoke Exposure and Intensive Care Use in Children Hospitalized With Bronchiolitis

OBJECTIVE

Among children hospitalized with bronchiolitis, we examined the associations between in utero exposure to maternal cigarette smoking, postnatal tobacco smoke exposure, and risk of admission to the intensive care unit (ICU).

METHODS

We performed a 16-center, prospective cohort study of hospitalized children aged <2 years with a physician admitting diagnosis of bronchiolitis. For 3 consecutive years, from November 1, 2007 until March 31, 2010, site teams collected data from participating families, including information about prenatal maternal smoking and postnatal tobacco exposure. Analyses used chi-square, Fisher's exact, and Kruskal-Wallis tests and multivariable logistic regression.

RESULTS

Among 2207 enrolled children, 216 (10%) had isolated in utero exposure to maternal smoking, 168 (8%) had isolated postnatal tobacco exposure, and 115 (5%) experienced both. Adjusting for age, sex, race, birth weight, viral etiology, apnea, initial severity of retractions, initial oxygen saturation, oral intake, and postnatal tobacco exposure, children with in utero exposure to maternal smoking had greater odds of being admitted to the ICU (adjusted odds ratio [aOR] 1.51, 95% confidence interval [CI] 1.14-2.00). Among children with in utero exposure to maternal smoking, those with additional postnatal tobacco exposure had a greater likelihood of ICU admission (aOR 1.95, 95% CI 1.13-3.37) compared to children without postnatal tobacco smoke exposure (aOR 1.47, 95% CI 1.05-2.04).

CONCLUSIONS

Maternal cigarette smoking during pregnancy puts children hospitalized with bronchiolitis at significantly higher risk of intensive care use. Postnatal tobacco smoke exposure may exacerbate this risk. Health care providers should incorporate this information into counseling messages.

Secondhand Smoke Exposure and Illness Severity among Children Hospitalized with Pneumonia

OBJECTIVE

To assess the relationship between secondhand smoke (SHS) exposure and disease severity among children hospitalized with community-acquired pneumonia (CAP).

STUDY DESIGN

Children hospitalized with clinical and radiographic CAP were enrolled between January 1, 2010, and June 30, 2012 at 3 hospitals in Tennessee and Utah as part of the Centers for Disease Control and Prevention's Etiology of Pneumonia in the Community study. Household SHS exposure was defined based on the number of smokers in the child's home. Outcomes included hospital length of stay, intensive care unit admission, and mechanical ventilation. Proportional hazards and logistic regression models were used to assess associations between SHS exposure and outcomes. All models were adjusted for age, sex, race/ethnicity, household education level, government insurance, comorbidities, enrollment site, year, and season.

RESULTS

Of the 2219 children included in the study, SHS exposure was reported in 785 (35.4%), including 325 (14.8%) with ≥2 smokers in the home. Compared with nonexposed children, the children exposed to ≥2 smokers had longer length of stay (median, 70.4 hours vs 64.4 hours; adjusted hazard ratio, 0.85; 95% CI, 0.75-0.97) and were more likely to receive intensive care (25.2% vs 20.9%; aOR, 1.44; 95% CI, 1.05-1.96), but not mechanical ventilation. Outcomes in children exposed to only 1 household smoker were similar to those in nonexposed children.

CONCLUSION

Children hospitalized with CAP from households with ≥2 smokers had a longer length of stay and were more likely to require intensive care compared with children from households with no smokers, suggesting that they experienced greater pneumonia severity.

Is secondhand smoke exposure associated with increased exacerbation severity among children hospitalized for asthma?

OBJECTIVE

To determine the association between secondhand smoke (SHS) exposure and length of stay (LOS) and other exacerbation severity indicators in children hospitalized for asthma.

METHODS

We conducted a retrospective chart review at 2 children's hospitals. Patients aged 2 to 18 hospitalized for asthma in 2012 were included. Outcome variables included LOS, PICU, magnesium, and intravenous (IV) steroids. Bivariate analysis determined differences between SHS-exposed and non-SHS-exposed groups. Geometric means were used for LOS to account for skewed distribution. Logistic and zero-truncated negative binomial regression models were used to determine the independent association between SHS exposure and hospitalization severity indicators.

RESULTS

A total of 623 patients were included; 41% reported SHS exposure. Mean LOS was 47.5 hours. In the SHS-exposed group, LOS was 50.0 (95% confidence interval [CI] 46.7-54.0) and in the nonexposed group it was 45.8 (95% CI 43.4-48.4) (P = .02). In regression analysis, institution modified the effect of SHS exposure on LOS. At Children's Hospital Colorado, SHS exposure was associated with a 20% increase in LOS (incidence rate ratio 1.2, 95% CI 1.1-1.3). At the Medical University of South Carolina, there was no significant association. SHS-exposed patients were more likely to receive IV steroids (odds ratio 1.6, 95% CI 1.1-2.3) CONCLUSIONS: Among children hospitalized for asthma, we identified a significant association at 1 institution between SHS exposure and LOS and found that IV steroid use was significantly associated with LOS at both institutions. Eliminating SHS exposure among children with asthma is important.

Routine screening of hospital patients for secondhand tobacco smoke exposure: a feasibility study

OBJECTIVE

Secondhand tobacco smoke (SHS) exposure causes over 40,000 deaths per year, but healthcare systems rarely address this risk factor. In September 2012, Massachusetts General Hospital initiated routine inpatient screening for SHS exposure by adding a question to the nurses' computerized admission assessment form ("Is smoking allowed in your home or car?"). We measured the implementation of this screening question over 1year.

METHODS

Multivariable analysis of hospital records of adult and pediatric admissions (N=35,701) from September 1, 2012 to August 31, 2013, to assess screening question completion and identify characteristics of nonsmokers who may be exposed to SHS.

RESULTS

Nurses entered "Yes" or "No" to the screening question for 91% of 34,295 adult admissions and 86% of 1406 pediatric admissions. Among nonsmokers, smoking in the home or car was allowed for 3% of adult admissions and 4% of pediatric admissions. Adults admitted for psychiatric diagnoses, children admitted for asthma, and patients with Medicaid insurance had higher odds of exposure to SHS in their home or car.

CONCLUSION

Routine screening of SHS among hospitalized patients by nurses is feasible. Doing so offers hospitals an opportunity to intervene and to promote smoke-free policies in patients' homes and cars.

Clinical practice guideline: the diagnosis, management, and prevention of bronchiolitis

This guideline is a revision of the clinical practice guideline, "Diagnosis and Management of Bronchiolitis," published by the American Academy of Pediatrics in 2006. The guideline applies to children from 1 through 23 months of age. Other exclusions are noted. Each key action statement indicates level of evidence, benefit-harm relationship, and level of recommendation. Key action statements are as follows:

Secondhand tobacco smoke exposure and severity of influenza in hospitalized children

OBJECTIVE

To assess whether children with influenza who are exposed to secondhand tobacco smoke (SHS) would have more severe illness than those not exposed.

STUDY DESIGN

We abstracted charts from pediatric inpatients with confirmed influenza from 2002-2009 for demographics, medical history, and smoke exposure. Severity indicators included intensive care, intubation, and length of stay (LOS) in the hospital; potential confounding factors included demographics and the presence of asthma or chronic conditions. All χ(2), t tests, and regression analyses were run using SPSS v. 18.0.

RESULTS

Of 117 children, 40% were exposed to SHS, who had increased need for intensive care (30% vs 10%, P < .01) and intubation (13% vs 1%, P < .05), and had longer LOS (4.0 vs 2.4 days, P < .01). Children with chronic conditions and SHS exposure required more intensive care (53% vs 18%, P < .05) and had longer LOS (10.0 vs 3.5 days, P < .01) than children not exposed to SHS with chronic conditions. In multivariate analyses controlling for potential confounding factors, children with SHS exposure were 4.7 times more likely to be admitted to intensive care (95% CI 1.4-18.5) and had a 70% longer LOS (95% CI 12%-230%).

CONCLUSIONS

Children with SHS exposure who are hospitalized with influenza have more severe illness. Efforts are needed to immunize this population against influenza, and eliminate children's exposure to SHS.
