RESUMO
BACKGROUND: Intensive care unit (ICU) admission is a risk factor for fatal asthma. Little is known about risk factors for pediatric ICU admissions for asthma. OBJECTIVE: To examine characteristics of underserved minority children with prior ICU admissions for asthma. METHODS: Baseline survey data, salivary cotinine levels, and allergen specific IgE serologic test results were obtained from children with uncontrolled asthma enrolled in a randomized clinical trial of a behavioral education environmental control intervention. Characteristics of children with and without prior ICU admission were compared using χ2 and t tests. Logistic regression assessed significance of higher odds of prior ICU admission comparing factor-level categories. RESULTS: Patients included 222 primarily African American (93.7%), male (56%), Medicaid-insured (92.8%) children with a mean (SD) age of 6.4 (2.7) years with uncontrolled asthma. Most (57.9%) had detectable cotinine levels, 82.6% were sensitized to more than 1 environmental allergen, and 27.9% had prior ICU admissions. Prior ICU patients were more likely to be very poor (<$10,000 per year) and sensitized to more than 1 allergen tested (most importantly mouse) (P < .05). Allergen sensitization in the groups did not differ for cockroach, cat, dog, Alternaria, Aspergillus, dust mite, grass, or tree. Although more ICU patients received combination controller therapy, they also overused albuterol. Only 27.4% of ICU patients received specialty care in the previous 2 years, which was not significantly different from non-ICU patients. CONCLUSION: Children with high mortality risk, including history of ICU admission, were twice as likely to live in extreme poverty, have atopy (particularly mouse allergen), use combination controller therapy, and overuse albuterol.

Objective: Urban children with asthma experience high rates of second hand smoke (SHS) exposure. The objective was to examine whether SHS exposure is associated with symptom frequency in children with poorly controlled asthma. Methods: Children were enrolled in a RCT to test the efficacy of an environmental control behavioral intervention versus an attention control group and followed over 12 months. SHS exposure assessed using salivary cotinine measurement. Frequency of child asthma symptoms, healthcare utilization, household smoking and caregiver daily life stress were obtained via caregiver report. Time of enrollment was recorded to assess seasonal factors. Symptom days and nights were the primary outcomes. Multivariable models and odds ratios examined factors that best predicted increased frequency of daytime/nighttime symptoms. Results: Children (n = 222) with a mean age of 6.3 (SD 2.7) years, were primarily male (65%), African American (94%), Medicaid insured (94%), and had poorly controlled asthma (54%). The final multivariable model indicated symptoms in the fall (OR 2.78; 95% CI 1.16, 6.52) and increased caregiver daily life stress (OR 1.13, 95% CI 1.02, 1.25) were significantly associated with increased symptom days when controlling for cotinine level, intervention status, child age and home and car smoking restrictions. Conclusions: There was no impact of SHS exposure on increased symptom frequency. High caregiver daily life stress and symptoms in fall season may place children with asthma at risk for increased day/nighttime symptoms. Close monitoring of symptoms and medication use during the fall season and intervening on caregiver life stress may decrease asthma morbidity in children with poorly controlled asthma.

BACKGROUND: Understanding health and social factors associated with controller medication use in children with high-risk asthma may inform disease management in the home and community. OBJECTIVE: To examine health and social factors associated with the Asthma Medication Ratio (AMR), a measure of guideline-based care and controller medication use, in children with persistent asthma and frequent emergency department (ED) use. METHODS: Study questionnaires, serum allergen sensitization, salivary cotinine, and pharmacy record data were collected for 222 children enrolled from August 2013 to February 2016 in a randomized clinical trial that tested the efficacy of an ED- and home-based intervention. Logistic regression was used to examine factors associated with an AMR greater than 0.50, reflecting appropriate controller medication use. RESULTS: Most children were male (64%), African American (93%), Medicaid insured (93%), and classified as having uncontrolled asthma (44%). Almost half (48%) received non-guideline-based care or low controller medication use based on an AMR less than 0.50. The final regression model predicting an AMR greater than 0.50 indicated that children receiving specialty care (odds ratio [OR], 4.87; 95% confidence interval [CI], 2.06-11.50), caregivers reporting minimal worry about medication adverse effects (OR, 0.50; 95% CI, 0.25-1.00), positive sensitization to ragweed allergen (OR, 3.82; 95% CI, 1.63-8.96), and negative specific IgE for dust mite (OR, 0.33; 95% CI, 0.15-0.76) were significantly associated with achieving an AMR greater than 0.50. CONCLUSION: Clinical decision making for high-risk children with asthma may be enhanced by identification of sensitization to environmental allergens, ascertaining caregiver's concerns about controller medication adverse effects and increased referral to specialty care.

BACKGROUND: One goal of guideline-based asthma therapy is minimal use of short-acting ß2 agonist (SABA) medications. Inner-city children with asthma are known to have high SABA use. OBJECTIVE: To examine factors associated with high SABA use in inner-city children with asthma. METHODS: One hundred inner-city children with persistent asthma were enrolled into a randomized controlled trial of an emergency department (ED) and home intervention. All children underwent serologic allergen specific IgE and salivary cotinine testing at the ED enrollment visit. Pharmacy records for the past 12 months were obtained. Number of SABA fills during the past 12 months was categorized into low- to moderate- vs high-use groups. SABA groups were compared by the number of symptom days and nights, allergen sensitization, and exposures. Regression models were used to predict high SABA use. RESULTS: Mean number of SABA fills over 12 months was 3.12. Unadjusted bivariate analysis showed that high SABA users were more than 5 times more likely to have an asthma hospitalization, almost 3 times more likely to have an asthma intensive care unit admission, and more than 3 times more likely to have prior specialty asthma care or positive cockroach sensitization than low to moderate SABA users. In the final regression model, for every additional inhaled corticosteroid fill, a child was 1.4 times more likely and a child with positive cockroach sensitization was almost 7 times more likely to have high SABA use when controlling for prior intensive care unit admission, receipt of specialty care, child age, and income. CONCLUSION: Providers should closely monitor SABA and controller medication use, allergen sensitization, and exposures in children with persistent asthma.

OBJECTIVES: Rates of preventive asthma care after an asthma emergency department (ED) visit are low among inner-city children. The objective of this study was to test the efficacy of a clinician and caregiver feedback intervention (INT) on improving preventive asthma care following an asthma ED visit compared to an attention control group (CON). METHODS: Children with persistent asthma and recent asthma ED visits (N = 300) were enrolled and randomized into a feedback intervention or an attention control group and followed for 12 months. All children received nurse visits. Data were obtained from interviews, child salivary cotinine levels and pharmacy records. Standard t-test, chi-square and multiple logistic regression tests were used to test for differences between the groups for reporting greater than or equal to two primary care provider (PCP) preventive care visits for asthma over 12 months. RESULTS: Children were primarily male, young (3-5 years), African American and Medicaid insured. Mean ED visits over 12 months was high (2.29 visits). No difference by group was noted for attending two or more PCP visits/12 months or having an asthma action plan (AAP). Children having an AAP at baseline were almost twice as likely to attend two or more PCP visits over 12 months while controlling for asthma control, group status, child age and number of asthma ED visits. CONCLUSIONS: A clinician and caregiver feedback intervention was unsuccessful in increasing asthma preventive care compared to an attention control group. Further research is needed to develop interventions to effectively prevent morbidity in high risk inner-city children with frequent ED utilization.

BACKGROUND: Children with asthma receiving specialty care have been found to have improved asthma outcomes. However, these outcomes can be adversely affected by poor adherence with controller medications. OBJECTIVE: To analyze pharmacy fill patterns as a measure of primary adherence in a group of underserved minority children receiving allergy subspecialty care. METHODS: As part of a larger 18-month nebulizer use study in underserved children (ages 2-8 years) with persistent asthma, 53 children were recruited from an urban allergy practice. Pharmacy records were compared with prescribing records for all asthma medications. RESULTS: Allergist controller prescriptions were written in 30-day quantities with refills and short-acting ß-agonists (SABAs) with no refills. Only 49.1% of inhaled corticosteroid (ICS), 49.5% of combination ICS and long-acting ß-agonist, and 64.5% of leukotriene modifier (LTM) initial and refill prescriptions were ever filled during the 18-month period. A mean of 5.1 refills (range, 0-14) for SABAs were obtained during 18 months, although only 1.28 SABA prescriptions were prescribed by the allergist. Mean times between first asthma prescription and actual filling were 30 days (range, 0-177 days) for ICSs, 26.6 days (range, 0-156 days) for LTMs, and 16.8 days (range, 0-139 days) for SABAs. CONCLUSION: Underserved children with asthma receiving allergy subspecialty care suboptimally filled controller prescriptions, yet filled abundant rescue medications from other prescribers. Limiting albuterol prescriptions to one canister without additional refills may provide an opportunity to monitor fill rates of both rescue and controller medications and provide education to patients about appropriate use of medications to improve adherence.

BACKGROUND: Rates of preventive follow-up asthma care after an acute emergency department (ED) visit are low among inner-city children. We implemented a novel behavioral asthma intervention, Pediatric Asthma Alert (PAAL) intervention, to improve outpatient follow-up and preventive care for urban children with a recent ED visit for asthma. OBJECTIVE: The objective of this article is to describe the PAAL intervention and examine factors associated with intervention completers and noncompleters. METHODS: Children with persistent asthma and recurrent ED visits (N = 300) were enrolled in a randomized controlled trial of the PAAL intervention that included two home visits and a facilitated follow-up visit with the child's primary care provider (PCP). Children were categorized as intervention completers, that is, completed home and PCP visits compared with noncompleters, who completed at least one home visit but did not complete the PCP visit. Using chi-square test of independence, analysis of variance, and multiple logistic regression, the intervention completion status was examined by several sociodemographic, health, and caregiver psychological variables. RESULTS: Children were African-American (95%), Medicaid insured (91%), and young (aged 3-5 years, 56%). Overall, 71% of children randomized to the intervention successfully completed all home and PCP visits (completers). Factors significantly associated with completing the intervention included younger age (age 3-5 years: completers, 65.4%; noncompleters, 34.1%; p < .001) and having an asthma action plan in the home at baseline (completers: 40%; noncompleters: 21%; p = .02). In a logistic regression model, younger child age, having an asthma action plan, and lower caregiver daily asthma stress were significantly associated with successful completion of the intervention. CONCLUSIONS: The majority of caregivers of high-risk children with asthma were successfully engaged in this home and PCP-based intervention. Caregivers of older children with asthma and those with high stress may need additional support for program completion. Further, the lack of an asthma action plan may be a marker of preexisting barriers to preventive care.

INTRODUCTION: The purpose of this study was to identify risk factors for primary medication nonadherence among low-income minority children with persistent asthma. METHOD: Data were from an environmental control and educational intervention for children with uncontrolled asthma who were treated in the emergency department for an asthma exacerbation. Presence or absence of pharmacy records for child asthma medications was the outcome of interest. A range of sociodemographic, health, and psychosocial measures were included in the binary logistic regression. RESULTS: Of the 222 youths (mean ageâ¯=â¯6.3 years; 93.7% Black), 25 (11.3%) lacked pharmacy records of asthma medications. For every 1-point increase in caregiver depressive symptoms, the odds of the child having a pharmacy record declined by 5% (odds ratioâ¯=â¯0.95; pâ¯=â¯.012). DISCUSSION: Providers should systematically assess and monitor caregiver depressive symptoms as a potential contributing factor for primary medication nonadherence in low-income minority children with persistent, uncontrolled asthma.

OBJECTIVES: To examine the association of social and environmental factors with levels of second-hand smoke (SHS) exposure, as measured by salivary cotinine, in young inner-city children with asthma. METHODS: We used data drawn from a home-based behavioral intervention for young high-risk children with persistent asthma post-emergency department (ED) treatment (N = 198). SHS exposure was measured by salivary cotinine and caregiver reports. Caregiver demographic and psychological functioning, household smoking behavior, and asthma morbidity were compared with child cotinine concentrations. Chi-square and ANOVA tests and multivariate regression models were used to determine the association of cotinine concentrations with household smoking behavior and asthma morbidity. RESULTS: Over half (53%) of the children had cotinine levels compatible with SHS exposure and mean cotinine concentrations were high at 2.42 ng/ml (SD 3.2). The caregiver was the predominant smoker in the home (57%) and 63% reported a total home smoking ban. Preschool aged children and those with caregivers reporting depressive symptoms and high stress had higher cotinine concentrations than their counterparts. Among children living in a home with a total home smoking ban, younger children had significantly higher mean cotinine concentrations than older children (cotinine: 3-5 year olds, 2.24 ng/ml (SD 3.5); 6-10 year olds, 0.63 ng/ml (SD 1.0); p < .05). In multivariate models, the factors most strongly associated with high child cotinine concentrations were increased number of household smokers (ß = 0.24) and younger child age (3-5 years) (ß = 0.23; p < .001, R(2) = 0.35). CONCLUSION: Over half of the young inner-city children with asthma were exposed to SHS, and caregivers are the predominant household smokers. Younger children and children with depressed and stressed caregivers are at significant risk of smoke exposures, even when a household smoking ban is reported. Further advocacy for these high-risk children is needed to help caregivers quit and to mitigate smoke exposure.

BACKGROUND: Effective pediatric guideline-based asthma care requires the caregiver to accurately relay the child's symptom frequency, pattern of rescue and controller medication use, and level of asthma control to the child's primary care clinician. OBJECTIVE: This study evaluated the longitudinal effects of a caregiver-clinician asthma communication education intervention (ACE) relative to an asthma education control group (CON) on symptom days and controller medication use in inner-city children with asthma. PARTICIPANTS AND METHODS: 231 inner-city children with asthma, recruited from urban pediatric emergency departments (EDs) and community practices, were followed for 12 months. Data included number of symptom days and nights, ED visits, hospitalizations, presence of limited activity, and controller medication use over 12 months. Pharmacy records were used to calculate controller to total asthma medication ratios as a proxy of appropriate controller medication use. Multivariate logistic regression models were used to identify factors associated with number of symptom days and nights over the past 30 days at the 12-month follow-up. RESULTS: Most caregivers rated the communication with their child's clinician as high. Unadjusted and adjusted rates of symptom days and nights did not differ by group at follow-up. ACE children tended towards a higher controller to total medication ratio at 12 months as compared to CON children (mean ratio: ACE: 0.54, SD 0.3; CON, 0.45, SD 0.4; p = .07). Activity limitation due to asthma and persistent asthma severity were the only factors significantly associated with reporting any symptom day within the past 30 days, adjusting for treatment group, number of oral corticosteroid courses and number of clinician visits in the last 6 months, seasonality, insurance type, and controller to total asthma medication ratio covariates. CONCLUSION: A home-based caregiver asthma communication educational intervention was not associated with decreased symptom days. However, a trend was noted in higher controller to total medication ratios in the intervention group. Inner-city caregivers of children with asthma may require a health systems approach to help convey the child's asthma health information to their clinician.

BACKGROUND: Lack of discussion regarding actual asthma medication use by physicians with caregivers of children with asthma may result in low caregiver and physician concordance about prescribed asthma medications. OBJECTIVE: The primary objective was to examine the concordance between primary care providers (PCP) and caregivers regarding child asthma medication use. METHODS: Current asthma medications in the home with verification from each child's PCP were obtained for 231 underserved children with persistent asthma. Kappas and chi-square statistics were calculated to measure the strength of the concordance. Caregiver and PCP dyads were categorized as concordant or discordant based on asthma medication use. RESULTS: For all asthma prescriptions N = 479, two thirds of caregiver-PCP dyads (67.8) were categorized as concordant with at least one asthma medication. Concordance for asthma medications varied by type of medication ranging from 84% agreement for albuterol and 77% agreement for Flovent. In the final regression model predicting caregiver and PCP concordance, the number of PCP visits within the past 6 months and caregiver report of no limitation of child's activity due to asthma were significantly higher in caregivers who were considered concordant with their child's PCP while controlling for child age and frequency of symptom nights and number of ED visits in prior 6 months. In a model predicting the number of PCP visits, the number of ED visits was the only significant variable associated with the number of PCP visits while controlling for caregiver and PCP concordance. CONCLUSION: Caregiver and PCP concordance was significantly associated with increased number of PCP visits suggesting that increased exposure to a health care provider may increase agreement between a child's PCP and caregiver regarding prescribed asthma medications. However, there may be other important factors including increased emergency department visits that may also be associated with subsequent pediatric primary care visits for asthma.

BACKGROUND: Few trials have tested targeted environmental control (EC) interventions based on biomarkers of second hand smoke (SHS) exposure and allergen sensitization in reducing asthma emergency department (ED) visits in children with poorly controlled asthma. METHODS: Overall, 222 children with poorly controlled asthma were randomized into a home-based EC intervention (INT) or control (CON) group and followed for ED visits over 12 months. All children received allergen-specific IgE serologic testing and SHS exposure biomarker testing to inform the EC intervention. Pharmacy data was examined for asthma medication fills. Cox proportional hazards and multivariate regression models were performed to examine factors associated with repeat ED visits. RESULTS: There was no difference in increased risk of >1 ED visit at 12 months between INT and CON groups. Most children (75%) had moderate/severe persistent asthma. Over half (56%) had SHS exposure and 83% tested positive for >1 allergen sensitization. Among children without SHS exposure, the median time to first recurrent ED visit differed by group (CON: 195; INT: >365 days) after adjusting for child age, allergic sensitization, medication fills prior to baseline, controller medication use, and the interaction between group status and SHS exposure. Children who had positive allergic sensitizations, younger, had increased controller medication use and randomized to the CON group and had no SHS exposure had increased risk for a repeat ED visit over 12 months. CONCLUSIONS: In this study, a home-based EC intervention was not successful in reducing asthma ED revisits in children with poorly controlled asthma with SHS exposure. Allergic sensitization, young age, and increased controller medication use were important predictors of asthma ED visits.

BACKGROUND: Management of asthma involves adherence to medication regimens. Assessing adherence is difficult for health care providers and researchers. Self-reported medication use is subjective, so objective methods of data collection for medication use are frequently used in asthma research. The aim of this project is to examine the concordance between asthma medication pharmacy data culled from Medicaid claims data ("Medicaid pharmacy data") and patient pharmacy record data obtained from individual pharmacies ("pharmacy record data"). METHODS: Medicaid pharmacy data and pharmacy record data were obtained from inner-city children enrolled in a prospective study of children with persistent asthma. A subject level comparison of pharmacy records and Medicaid pharmacy data pharmacy records was done to determine concordance between the 2 data collection methods. RESULTS: Of 513 children recruited for inclusion, 221 were consented and randomized. Medicaid claims data were collected on 72.8% (n=161) of the 221 enrolled subjects. Pharmacy record data were available on 96.8% (n=214) of the 221 subjects. Data presented represent the 159 subjects who had both Medicaid claims data and pharmacy records data available throughout the study period. There was complete agreement between Medicaid pharmacy data and pharmacy record for 26% (n=42) of subjects. A total of 1858 asthma medication claims were captured by the Medicaid pharmacy data. Medicaid pharmacy data missed 149 claims that were capture by the pharmacy record data. Medicaid pharmacy data failed to capture a single claim on 4.4% (n=7) of subjects. The pharmacy record data captured a total of 1627 asthma medication claims and missed 371 claims that were captured by the Medicaid pharmacy data. Pharmacy record data failed to capture a single claim in 1.9% (n=3) of subjects. CONCLUSIONS: There was overlap between the pharmacy data captured by the Medicaid pharmacy dataset and pharmacy record dataset, but the overall concordance between the two data collection methods was low. Pharmacy records collected directly from the pharmacy included data on more subjects and pharmacy data culled from Medicaid claims captured more total number of claims. In spite of the differences in the methods used to collect data, pharmacy fill records are a rich source of data with both clinical and research applications. Clinicians and researchers must weigh the benefits and limitations of each method used to collect pharmacy data.

OBJECTIVE: To determine whether temporal trends exist for short-acting beta agonist (SABA), oral corticosteroid (OCS), and anti-inflammatory prescription fills in children with persistent asthma. METHOD: This was a longitudinal analysis of pharmacy record data and health information data obtained by parent report over 12 months for children with persistent asthma 2 to 9 years of age. Eligible children had to report current nebulizer use and one or more emergency department visits or hospitalizations within the past 12 months. RESULTS: Children were primarily African-American (89%), male (64%), received Medicaid health insurance (82%), and were a mean age of 4.5 years (SD 2.1). Few families (11%) reported any problems paying for their child's asthma medications at baseline or at the 12-month follow-up. There was a high degree of association between filling a rescue (SABA or OCS) and controller (leukotriene modifier, inhaled corticosteroid, cromolyn) medication during the same month for all months with Pearson's correlation coefficients ranging from a low of 0.28 for October to a high of 0.53 in September. Short-acting beta agonist fills were significantly more likely to be filled concurrently with inhaled corticosteroid fills. However, significantly fewer prescription fills were obtained in the summer months with an acceleration of medication fills in September through December and an increase in early spring. CONCLUSIONS: There was a summer decline in both inhaled corticosteroid and SABA fills. Timing of asthma monitoring visits to occur before peak prescription fill months, i.e., August and December for an asthma "tune-up," theoretically could improve asthma control. During these primary care visits children could benefit from more intensive monitoring of medication use including monitoring lung function, frequency of prescription refills, and assessment of medication device technique to ensure that an effective dose of medication is adequately delivered to the respiratory tract. Additionally, scheduling non-urgent asthma care visits at pre-peak prescription fill months can take advantage of "step down" during decreased symptom periods and when appropriate restart daily controller medications to "step up" prior to peak asthma periods.

BACKGROUND: Very poorly controlled (VPC) asthma in children is associated with ongoing acute exacerbations but factors associated with VPC are understudied. OBJECTIVE: To examine the risk factors associated with VPC asthma in urban minority children. METHODS: This descriptive study examined asthma control levels (well-controlled [WC], not well-controlled [NWC], and VPC) at baseline and 6 months in children participating in an ongoing randomized controlled trial of an emergency department/home environmental control intervention. Data collection occurred during the index emergency department visit and included allergen-specific IgE and salivary cotinine testing and caregiver interview of sociodemographic and child health characteristics. Follow-up data were collected at 6 months. Unadjusted analyses examined the association of sociodemographic and health characteristics by level of asthma control. Multivariate analysis tested significant factors associated with VPC asthma at 6 months. RESULTS: At baseline most children were categorized with VPC asthma (WC, 0%; NWC, 47%; VPC, 53%) and rates of VPC minimally improved at 6 months (WC, 13%; NWC, 41%; VPC, 46%). Risk for VPC asthma was twice as likely in children with allergic rhinitis (odds ratio [OR], 2.42), having 2 or more primary care provider asthma visits within the past 3 months (OR, 2.77), or caregiver worry about medication side effects (OR, 2.13) and 3 to 4 times more likely when asthma control was assessed during the fall or spring season (OR: fall, 3.32; spring, 4.14). CONCLUSIONS: Improving asthma control in low-income, high-risk children with VPC asthma requires treatment of comorbidities, attention to caregiver medication beliefs, and adept use of stepwise therapy.

Dyspnea, a common distressing end-of-life symptom, is treated with oral (i.e., opioids and anxiolytics) and inhaled medications (anti-inflammatory and bronchodilator agents). Health care providers and patients have demonstrated an inability to use inhaler devices correctly, which can lead to suboptimal drug delivery and poor symptom relief. Hospice nurses are the primary health care providers educating patients, making it critical that they convey accurate device technique. This study assessed hospice nurses' ability to demonstrate proper inhaler device technique and their knowledge of agents used to treat dyspnea. Forty-seven nurses participated. Participants completed a written questionnaire, which gathered demographic data, as well as information regarding previous training with an inhaler device, administration, pharmacokinetics, mechanism of action, patient assessment, and nursing technique. Additionally, each nurse demonstrated the use of a metered dose inhaler, spacer, dry powder inhaler, and a nebulizer, while being observed by a pharmacist trained in the use of inhalers. A standardized evaluation form was used to ensure consistency between evaluators and subjects. Percentage of steps completed correctly by the study participants ranged from 34.9% with the dry powder inhaler to 67.6% with the metered dose inhaler. Years of experience, presence of hospice certification, personal use of inhaler, and nursing comfort level significantly impacted ability to use inhalation devices. This study demonstrated the existence of knowledge gaps regarding patient assessment, pharmacology and pharmacokinetics of inhaled medications, and inhalation device technique among hospice nurses. Formal education of hospice practitioners regarding inhaled medications and inhalation delivery devices is needed.

OBJECTIVE: To explore various factors that may influence community pharmacists' pediatric asthma counseling. DESIGN: Cross-sectional. SETTING: Maryland from September 2002 through March 2003. PARTICIPANTS: Random sample of 400 community pharmacists. INTERVENTION: Mail survey. MAIN OUTCOME MEASURES: Pharmacists' attitude, subjective norm, perceived behavioral control, intention to provide pediatric asthma counseling, and reported counseling using the theory of planned behavior as a framework; demographic and pharmacy characteristics. RESULTS: 98 of 389 (25%) eligible pharmacists responded. Most acknowledged the importance of providing asthma counseling to children (54%) or caregivers (68%). However, only a small number reported demonstrating to children or caregivers or asking them to demonstrate how to use antiasthmatic medications. Multivariate logistic regressions revealed that intention to counsel was a significant predictor of providing counseling for children or caregivers (odds ratio [OR], 3.95 and 3.09, respectively). Intention to counsel children was significantly associated with subjective norm (OR, 1.88) and perceived ease of counseling (OR, 1.48); intention to counsel caregivers was significantly associated with perceived ease (OR, 1.45). Pharmacists also reported the following barriers that made counseling difficult: lack of time, lack of parent's interest, and lack of placebo devices useful for demonstration of inhalation technique. CONCLUSION: Despite a positive attitude toward providing asthma counseling, the majority of pharmacists reported not fully engaging in counseling. A number of barriers to counseling were reported that, if targeted, could improve the management of pediatric asthma through pharmacist-initiated counseling.
