Asthma symptoms, morbidity, and antiinflammatory use in inner-city children

Pressure Injury Data Reconciliation in a Randomized Controlled Trial

OBJECTIVE

To advance pressure injury (PrI) research in individuals with spinal cord injury (SCI) by describing lessons learned and recommendations for future research, ultimately promoting PrI prevention and more effective wound care. This paper describes the detailed procedures undertaken to collect and reconcile PrI data and summarizes the types of discrepancies identified.

DESIGN

Secondary analyses of PrI data collected between 2009 and 2014 in a randomized controlled trial (parent study).

SETTING

Participants in the parent study were recruited from a large rehabilitation center in the Los Angeles area that serves primarily individuals with limited resources.

PARTICIPANTS

232 participants with SCI and a history of 1 or more medically serious PrI (MSPrI) in the previous 5 years.

INTERVENTIONS

Participants in the parent study were randomized to a 12-month PrI prevention intervention led by an occupational therapist, or to usual care.

MAIN OUTCOME MEASURES

Relations among PrI characteristics, data sources (phone interviews, skin checks, paper and electronic medical records [MRs]), and treatment condition, and sensitivity of 6 different data sources in detecting MSPrIs.

RESULTS

The majority (62%) of MSPrIs were in the pelvic region. MRs detected 82% of the MSPrIs overall, making it the most sensitive data source, and scheduled skin checks were the second-most sensitive data source, finding 37% of the MSPrIs.

CONCLUSIONS

MR review is the preferred method for ascertaining MSPrIs in clinical trials of interventions designed to reduce the incidence of these injuries. When multiple sources of information are used, careful reconciliation of reports is necessary to ensure accuracy.

A higher Asthma Medication Ratio (AMR) predicts a decrease in ED visits among African American and Hispanic children

INTRODUCTION

Higher rates of ED visits and hospitalizations for asthma among African American and Hispanic children may indicate suboptimal management of asthma, leading to a greater financial burden of healthcare. It is not well known if an association of race/ethnicity with controller medication and hospital-based care utilization exists.

OBJECTIVE

This study examines whether the Asthma Medication Ratio (AMR) predicts healthcare utilization for asthma by race/ethnicity.

METHODS

4,584 Medi-Cal children (Ages 5-11) with persistent asthma in Los Angeles were identified and their AMRs (2018) were calculated based on the HEDIS criteria. Healthcare utilization data were used, including hospitalizations, ED visits, and pharmacy claims to examine whether a higher AMR predicts decreases in healthcare utilization by race/ethnicity in the subsequent 3,6, and 12 months (2019).

RESULTS

The average AMR was lowest among African American children (0.401). In the subsequent 12 months, they were highest in ED visits (0.249) and hospitalizations (0.121), but lowest in outpatient visits (0.793). The results of logistic regression showed that a higher value of AMR (>0.5) contributed to decreases in ED visits in the subsequent 12 months only among African Americans (OR = 0.551, 95% CI 0.364-0.832) and Hispanics (OR = 0.613, 95% CI 0.489-0.770). No association between AMR and hospitalizations was found.

CONCLUSIONS

Our findings indicate that increased use of controller medication contributes to a decrease in ED visits among African American and Hispanic children with persistent asthma. Increased use of controller medications and caregiver's efforts for medication adherence may contribute to a reduction in asthma disparities.

A pilot school-based health center intervention to improve asthma chronic care in high-poverty schools

OBJECTIVE

To test the feasibility and effectiveness of a multifaceted intervention administered through school-based health centers (SBHCs) to improve asthma control for children in high-poverty schools with not well controlled asthma.

METHODS

Students 4-14 years old with persistent asthma were enrolled from three SBHCs. The centers' advanced practice providers received training on evidence-based asthma guidelines. Students randomized to the intervention received directly observed therapy of their asthma controller medication, medication adjustments as needed by the centers' providers, and daily self-management support. Students randomized to usual care were referred back to their primary care provider (PCP) for routine asthma care.

RESULTS

We enrolled 29 students. Students in the intervention group received their controller medication 92% of days they were in school. Ninety-four percent of follow-up assessments were completed. During the study, 11 of 12 intervention students had a step-up in medication; 2 of 15 usual care students were stepped up by their PCP. Asthma Control Test scores did not differ between groups, although there were significant improvements from baseline to the 7 month follow-up within each group (both p < .01). Both FEV1% predicted and FEV1/FVC ratio significantly worsened in the usual care group (both p = .001), but did not change in the intervention group (p = .76 and .28 respectively).

CONCLUSIONS

Our pilot data suggest that a multifaceted intervention can be feasibly administered through SBHCs in communities with health disparities. Despite the small sample size, spirometry detected advantages in the intervention group. Further study is needed to optimize the intervention and evaluate outcomes.

Improved asthma outcomes among at-risk children in a pharmacist-led, interdisciplinary school-based health clinic: A pilot study of the CAReS program

BACKGROUND

Disparities in access to care and outcomes have been identified among children with asthma living in underserved communities. The Caring for Asthma in our Region's Schoolchildren program was established to reduce disparities by providing school-based, comprehensive asthma care by a pharmacist-led, interdisciplinary team to high-risk pediatric populations in the Greater Pittsburgh area.

OBJECTIVE

To investigate program impact on follow-up appointment attendance, delivery of guideline-based care, asthma control, asthma morbidity (emergency department [ED] visits, oral corticosteroid [OCS] requirement), and asthma-related knowledge and quality of life.

METHODS

The study enrolled 50 children with asthma from 6 elementary schools (September 2014-December 2017). Children completed 5 visits over a 3-month period. McNemar's test assessed improvement in guideline-based controller therapy use and reduced morbidity (ED visits or OCS requirement). Generalized estimating equation analyses determined the significance of monthly improvements in asthma control, asthma knowledge, and quality of life.

RESULTS

A 100% show rate was achieved in nearly all participants (92.0%). Most of the patients were African-American (56%). In children with persistent disease, only 21.4% were prescribed controller therapy at baseline, which improved to 78.5% upon enrollment (P < 0.05). Asthma control statistically significantly improved (P < 0.05), and a reduction in percentage of patients who required an ED visit or an OCS burst pre-to postintervention was also statistically significant (31.3% vs. 14.6%, P < 0.05). The goal of 100% treatment plan knowledge was achieved in 67% of caregivers within 1 month and increased from 6% to 60% in children over 3 months (P < 0.05). Asthma-related quality of life also improved statistically significantly pre-to postintervention (P < 0.05).

CONCLUSIONS

Disparities in asthma outcomes owing to inadequate access to health care can be addressed. Improved asthma control, asthma medication knowledge, quality of life, and reduced morbidity in high-risk pediatric patients are achievable as demonstrated by our study. Our findings support the feasibility and value of a pharmacist-led, interdisciplinary school-based health care delivery model in providing comprehensive asthma care to at-risk pediatric populations.

Impact of guideline adherence and race on asthma control in children

BACKGROUND

Asthma control in African Americans (AA) is considered more difficult to achieve than in Caucasian Americans (CA). The aim of this study was to compare asthma control over time among AA and CA children whose asthma is managed per NAEPP (EPR-3) guidelines.

METHODS

This was a one-year prospective study of children referred by their primary care physicians for better asthma care in a specialty asthma clinic. All children received asthma care per NAEPP guidelines. Results were compared between CA and AA children at baseline and then at three-month intervals for one year.

RESULTS

Of the 345 children, ages 2-17 years (mean = 6.2 ± 4), 220 (63.8%) were CA and 125 (36.2%) were AA. There were no significant differences in demographics other than greater pet ownership in CA families. At baseline, AA children had significantly more visits to the Emergency Department for acute asthma symptoms (mean = 2.3 [Formula: see text] compared to CA (1.4 ± 2.3, P = 0.003). There were no other significant differences in acute care utilization, asthma symptoms (mean days/month), or mean asthma control test (ACT) scores at baseline. Within 3-6 months, in both groups, mean ACT scores, asthma symptoms and acute care utilization significantly improved (P < 0.05 for all) and change over time in both groups was comparable except for a significantly greater decrease in ED visits in AA children compared to CA children (P = 002).

CONCLUSION

Overall, improvement in asthma control during longitudinal assessment was similar between AA and CA children because of  consistent use of NAEPP asthma care guidelines.

Pediatric Asthma: A Global Epidemic

The global prevalence, morbidity and mortality related to childhood asthma among children has increased significantly over the last 40 years. Although asthma is recognized as the most common chronic disease in children, issues of underdiagnosis and undertreatment persist. There are substantial global variations in the prevalence of asthma symptoms in children, with up to 13-fold differences between countries. The rising number of hospital admissions for asthma may reflect an increase in asthma severity, poor disease management and/or the effect of poverty. The financial burden of asthma is relatively high within developed countries (those for which data is available) spending 1 to 2% of their healthcare budget on this condition. Established in 1989, the Global Initiative for Asthma (GINA) attempts to raise awareness about the increasing prevalence of asthma, improve management and reduce the burden of asthma worldwide. Despite global efforts, GINA has not achieved its goal, even among developed nations. There are multiple barriers to reducing the global burden of asthma, including limited access to care and/or medications, and lack of prioritization as a public healthcare priority. In addition, the diversity of healthcare systems worldwide and large differences in access to care require that asthma management guidelines be tailored to local needs.

Does co-payment for inhaler devices affect therapy adherence and disease outcomes? A historical, matched cohort study

BACKGROUND

Adherence to asthma and chronic obstructive pulmonary disease (COPD) treatment has been shown to depend on patient-level factors, such as disease severity, and medication-level factors, such as complexity. However, little is known about the impact of prescription charges - a factor at the health care system level. This study used real-life data to investigate whether co-payment affects adherence (implementation and persistence) and disease outcomes in patients with asthma or COPD.

METHODS

A matched, historical cohort study was carried out using two UK primary care databases. The exposure was co-payment for prescriptions, which is required for most patients in England but not in Scotland. Two comparison cohorts were formed: one comprising patients registered at general practices in England and the other comprising patients registered in Scotland. Patients aged 20-59 years with asthma, or 40-59 years with COPD, who were initiated on fluticasone propionate/salmeterol xinafoate, were included, matched to patients in the opposite cohort, and followed up for 1 year following fluticasone propionate/salmeterol xinafoate initiation. The primary outcome was good adherence, defined as medication possession ratio ≥80%, and was analyzed using conditional logistic regression. Secondary outcomes included exacerbation rate.

RESULTS

There were 1,640 patients in the payment cohort, ie, England (1,378 patients with asthma and 262 patients with COPD) and 619 patients in the no-payment cohort, ie, Scotland (512 patients with asthma and 107 patients with COPD). The proportion of patients with good adherence was 34.3% and 34.9% in the payment and no-payment cohorts, respectively, across both disease groups. In a multivariable model, no difference in odds of good adherence was found between the cohorts (odds ratio, 1.04; 95% confidence interval, 0.85-1.27). There was also no difference in exacerbation rate.

CONCLUSION

There was no difference in adherence between matched patients registered in England and Scotland, suggesting that prescription charges do not have an impact on adherence to treatment.

The Danish National Database for Asthma: establishing clinical quality indicators

Asthma is one of the most common chronic diseases worldwide affecting more than 300 million people. Symptoms are often non-specific and include coughing, wheezing, chest tightness, and shortness of breath. Asthma may be highly variable within the same individual over time. Although asthma results in death only in extreme cases, the disease is associated with significant morbidity, reduced quality of life, increased absenteeism, and large costs for society. Asthma can be diagnosed based on report of characteristic symptoms and/or the use of several different diagnostic tests. However, there is currently no gold standard for making a diagnosis, and some degree of misclassification and inter-observer variation can be expected. This may lead to local and regional differences in the treatment, monitoring, and follow-up of the patients. The Danish National Database for Asthma (DNDA) is slated to be established with the overall aim of collecting data on all patients treated for asthma in Denmark and systematically monitoring the treatment quality and disease management in both primary and secondary care facilities across the country. The DNDA links information from population-based disease registers in Denmark, including the National Patient Register, the National Prescription Registry, and the National Health Insurance Services register, and potentially includes all asthma patients in Denmark. The following quality indicators have been selected to monitor trends: first, conduction of annual asthma control visits, appropriate pharmacological treatment, measurement of lung function, and asthma challenge testing; second, tools used for diagnosis in new cases; and third, annual assessment of smoking status, height, and weight measurements, and the proportion of patients with acute hospital treatment. The DNDA will be launched in 2016 and will initially include patients treated in secondary care facilities in Denmark. In the nearby future, the database aims to include asthma diagnosis codes and clinical data registered by general practitioners and specialised practitioners as well.

Parent and Child Independent Report of Emotional Responses to Asthma-Specific Vignettes: The Relationship Between Emotional States, Self-Management Behaviors, and Symptoms

Little is known about the emotional intelligence (EI) of parents and their children with asthma. Objectives of this study were to assess: 1) parent's and children's report of emotions in response to an asthma vignette (proxy for EI) and 2) the relationship between emotions, self-management behaviors, and symptoms.

DESIGN AND METHODS

We conducted a descriptive, mixed methods study of children 7-12 years old with asthma. Parent-Child dyads (n=104) responded to an asthma vignette to gain insight into emotions, symptoms, and self-management behaviors. Additional questions assessed confidence and worry using a 5-point Likert scale. Thematic analyses and descriptive statistics were used to assess qualitative and quantitative outcomes.

RESULTS

Children were predominantly male (58%), 7-9 (58%), and White (46%). The most common negative emotions reported by children were scared and sad. Children who sought help from an adult were less likely to report using medications compared to children who did not seek help (39.5% vs. 62.3%, p=.029). Children with low worry and high confidence had fewer symptoms compared to children reporting high worry and low confidence (symptoms: days 3.24 vs. 6.77, p=.012, nights 2.71 vs. 5.36, p=.004).

CONCLUSIONS

Children provided appropriate emotional responses to the asthma vignette; emotions were related to self-management behaviors and symptoms. More studies are needed to specifically assess EI in this population.

PRACTICE IMPLICATIONS

Parents and children with greater EI may be better able to understand their needs, engage in self-management behaviors, and communicate with their nurses, to improve their support network and ability to access services.

The relationships among family management behaviors and asthma morbidity in maternal caregivers of children with asthma

Numerous studies have identified the relationship of the family caregiver's perception regarding asthma management and the child's asthma outcomes, although few have examined family caregiver asthma management behaviors. The primary aim of this study was to examine the relationship among family management behaviors and asthma morbidity as perceived by maternal caregivers. The Family Management Style Framework was used to guide the research. Maternal caregivers (N = 101) with school-aged children diagnosed with persistent asthma and living in the United States were recruited from a specialty asthma clinic. When caregivers perceived they were expending much effort on their child's asthma management and were not confident in their ability to perform management activities, the child's asthma outcomes were worse. This is the first study to examine family management behaviors with maternal caregivers of school-aged children with asthma. Findings from this study encourage health care providers to tailor each educational opportunity with families to improve child asthma outcomes. An ongoing effort must be made to include families in asthma management. Health care partnerships between provider and family can lead to improved asthma management.

The relationship between helplessness and the child's asthma symptoms: the role of social support

OBJECTIVE

Objectives of this study were to survey parents and children independently regarding feelings of helplessness specific to asthma and to examine the relationship between helplessness and the child's symptom-free days.

METHODS

Parent-child dyads (children 7-12 years) from Rochester, NY were enrolled (November 2011-August 2012) from general pediatric clinics, pulmonary clinics, an Emergency Department, and area youth and asthma programs. Assessments included demographics, symptoms, ratings of helplessness related to asthma and parent social support. A multivariate linear regression was conducted to examine the relationship between feelings of helplessness and symptoms-free days: post hoc analysis assessed the moderating role of social support.

RESULTS

Overall, 107 parent-child dyads enrolled (participation rate: 72%); 104 were included in analysis. Most children were male (58%), 7-9 years (58%) and White (46%). The child's feelings of helplessness scores were positively correlated with symptom-free days indicating less feelings of helplessness as symptom-free days increased (rs = 0.273, p = 0.01). In a stratified analysis, among parents who reported minimal social support (<1 sources of support), child's helplessness scores were positively correlated with symptom-free days (rs = 0.335, p = 0.02). Conversely, among parents reporting >2 supports, no relationship was found (rs = 0.195, p = 0.15).

CONCLUSIONS

This study found less feelings of helplessness among children with asthma as symptom-free days increased. Social support appears to moderate this relationship; however further studies to confirm these findings are needed.

Implementing asthma guidelines using practice facilitation and local learning collaboratives: a randomized controlled trial

PURPOSE

Guideline implementation in primary care has proven difficult. Although external assistance through performance feedback, academic detailing, practice facilitation (PF), and learning collaboratives seems to help, the best combination of interventions has not been determined.

METHODS

In a cluster randomized trial, we compared the independent and combined effectiveness of PF and local learning collaboratives (LLCs), combined with performance feedback and academic detailing, with performance feedback and academic detailing alone on implementation of the National Heart, Lung and Blood Institute's Asthma Guidelines. The study was conducted in 3 primary care practice-based research networks. Medical records of patients with asthma seen during pre- and postintervention periods were abstracted to determine adherence to 6 guideline recommendations. McNemar's test and multivariate modeling were used to evaluate the impact of the interventions.

RESULTS

Across 43 practices, 1,016 patients met inclusion criteria. Overall, adherence to all 6 recommendations increased (P ≤.002). Examination of improvement by study arm in unadjusted analyses showed that practices in the control arm significantly improved adherence to 2 of 6 recommendations, whereas practices in the PF arm improved in 3, practices in the LLCs improved in 4, and practices in the PF + LLC arm improved in 5 of 6 recommendations. In multivariate modeling, PF practices significantly improved assessment of asthma severity (odds ratio [OR] = 2.5, 95% CI, 1.7-3.8) and assessment of asthma level of control (OR = 2.3, 95% CI, 1.5-3.5) compared with control practices. Practices assigned to LLCs did not improve significantly more than control practices for any recommendation.

CONCLUSIONS

Addition of PF to performance feedback and academic detailing was helpful to practices attempting to improve adherence to asthma guidelines.

Symptoms, feelings, activities and medication use in adolescents with uncontrolled asthma: lessons learned from asthma diaries

This study was to describe symptoms, feelings, activities and medication use reported by adolescents with uncontrolled asthma on their 24-hour asthma diaries. Adolescents with uncontrolled asthma (13-17 years, N=29) completed asthma diaries and audio-recorded symptom sounds for 24 hours. A variety of symptoms were reported, and the most frequently reported symptoms were coughing followed by wheezing. Most self-reported coughing and wheezing were verified by audio-recordings. Participants reported predominantly negative feelings and low levels of activities. High discordance between self-reports and medical records in medications was noted, raising a concern of poor treatment adherence in this vulnerable group.

Asthma medication ratio predicts emergency department visits and hospitalizations in children with asthma

OBJECTIVE

To determine if the asthma medication ratio predicts subsequent emergency department (ED) visits and hospital admissions in children.

DESIGN

Retrospective cohort with two year pairs.

SETTING/PARTICIPANTS

2007-2009 South Carolina Medicaid recipients with persistent asthma age 2-18.

MAIN EXPOSURE

Controller-to-total asthma medication ratios were calculated for each patient in 2007 and 2008. Ratios range from 0-1 (1 = ideal, 0 = no controller).

OUTCOME MEASURES

2008 and 2009 asthma related ED visits, hospitalizations, and a combined outcome of ED visit or hospitalization in the subsequent 3, 6, and 12 month time periods.

RESULTS

19,512 patients were included. Mean age 8.9 years, 58% male, and 55% black. The ratio significantly predicted ED visits and hospitalizations over subsequent 3, 6, and 12 month time periods. The cut-point that maximized the ability to predict visits ranged from 0.4-0.6. A cutpoint of 0.5 was used in the final models. After controlling for age, race, gender, and rurality, patients with a ratio <0.5 were significantly more likely to have a subsequent emergent healthcare visit (OR 1.5-2.0). The ratio retained its predictive ability in both year-pairs for all three outcome variables, in all three time periods, with the exception of the 2008 ratio not predicting 2009 3-month and 6-month hospitalizations.

CONCLUSIONS

The asthma medication ratio is a significant predictor of ED visits and hospitalizations in children. Using a cutoff of <0.5 to signal at-risk patients may be an effective way for populations who would benefit from increased use of controller medications to reduce future emergent asthma visits.

The Pediatric Asthma Control and Communication Instrument for the Emergency Department (PACCI-ED) improves physician assessment of asthma morbidity in pediatric emergency department patients

OBJECTIVES

To determine whether the Pediatric Asthma Control and Communication Instrument for the Emergency Department (PACCI-ED), a 12-item questionnaire, can help ED attendings accurately assess a patient's asthma control and morbidity.

METHODS

This was a randomized-controlled trial performed at an urban pediatric ED of children aged 1-17 years presenting with an asthma exacerbation. Parents answered PACCI-ED questions about their children's asthma. Attendings were randomized to view responses to the PACCI-ED (intervention group) or to be blinded to the completed PACCI-ED (control group). The two groups were compared on their empirical clinical assessment of: (1) chronic asthma control categories, (2) asthma trajectory (stable, worsening or improving), (3) patient adherence to controller medications, and (4) burden of disease for the patient's family. The validated PACCI algorithm was used as the criterion standard for these four outcomes. Accuracy of clinical assessment was compared between intervention and control groups using chi-squared tests and an intention-to-treat approach.

RESULTS

Seventeen ED attendings were enrolled in the study and 77 children visits were included in the analysis. There were no significant differences between the intervention and the control groups for child's gender, age, race, and asthma characteristics. Intervention group attendings were more accurate than control group attendings in assessing the category of chronic asthma control (43% versus 19%; p = 0.03), disease trajectory (72% versus 45%; p = 0.02), and the disease burden for families (74% versus 35%; p = 0.001) over the past 12 months. There was a trend towards more accuracy of intervention versus control attendings for estimating patient adherence to controller medications (72% versus 48%; p = 0.06).

CONCLUSIONS

The PACCI-ED improves the assessment of asthma control, trajectory, and burden by ED attendings, and may help assessment of asthma medication adherence and prior asthma exacerbations. The PACCI-ED can be used to improve provider assessment of asthma morbidity during pediatric ED visits for asthma exacerbations, and to identify children who may benefit from interventions to reduce asthma morbidity.

Intermittent versus daily inhaled corticosteroids for persistent asthma in children and adults

BACKGROUND

Daily inhaled corticosteroids (ICS) are the recommended mainstay of treatment in children and adults with persistent asthma. However, often, ICS are used intermittently by patients or recommended by physicians to be used only at the onset of exacerbations.

OBJECTIVES

The aim of this review was to compare the efficacy and safety of intermittent versus daily ICS in the management of children and adults with persistent asthma and preschool-aged children suspected of persistent asthma.

SEARCH METHODS

We searched the Cochrane Airways Group Specialised Register of trials (CAGR) and the ClinicalTrials.gov web site up to October 2012.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) that compared intermittent ICS versus daily ICS in children and adults with persistent asthma. No co-interventions were permitted other than rescue relievers and oral corticosteroids used during exacerbations.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trials for inclusion, methodological quality and extracted data. The primary efficacy outcome was the number of patients with one or more exacerbations requiring oral corticosteroids and the primary safety outcome was the number of patients with serious adverse health events. Secondary outcomes included exacerbations, lung function tests, asthma control, adverse effects, withdrawal rates and inflammatory markers. Equivalence was assumed if the risk ratio (RR) estimate and its 95% confidence interval (CI) were between 0.9 and 1.1. Quality of the evidence was assessed using GRADE.

MAIN RESULTS

Six trials (including one trial testing two relevant protocols) met the inclusion criteria for a total of seven group comparisons. The four paediatric trials (two involving preschool children and two school-aged children) and two adult parallel-group trials, lasting 12 to 52 weeks, were of high methodological quality. A total of 1211 patients with confirmed, or suspected, persistent asthma contributed to the meta-analyses. There was no statistically significant group difference in the risk of patients experiencing one or more exacerbations requiring oral corticosteroids (1204 patients; RR 1.07; 95% CI 0.87 to 1.32; the large confidence interval translates into a risk of exacerbations in the intermittent ICS group varying between 17% and 25%, assuming a 19% risk with daily ICS). Age, severity of airway obstruction, step-up protocol used during exacerbations and trial duration did not significantly influence the primary efficacy outcome. No group difference was observed in the risk of patients with serious adverse health events (1055 patients; RR 0.82; 95% CI 0.33 to 2.03). Compared to the daily ICS group, the intermittent ICS group displayed a smaller improvement in change from baseline peak expiratory flow rate (PEFR) by 2.56% (95% CI -4.49% to -0.63%), fewer symptom-free days (standardised mean difference (SMD) -0.15 (95% CI -0.28 to -0.03), fewer asthma control days -9% (95% CI -14% to -4%), more use of rescue β2-agonists by 0.12 puffs/day (95% CI 0 to 0.23) and a greater increase from baseline in exhaled nitric oxide of 16.80 parts per billion (95% CI 11.95 to 21.64). There was no significant group difference in forced expiratory volume in one second (FEV1), quality of life, airway hyper-reactivity, adverse effects, hospitalisations, emergency department visits or withdrawals. In paediatric trials, intermittent ICS (budesonide and beclomethasone) were associated with greater growth by 0.41 cm change from baseline (532 children; 95% CI 0.13 to 0.69) compared to daily treatment.

AUTHORS' CONCLUSIONS

In children and adults with persistent asthma and in preschool children suspected of persistent asthma, there was low quality evidence that intermittent and daily ICS strategies were similarly effective in the use of rescue oral corticosteroids and the rate of severe adverse health events. The strength of the evidence means that we cannot currently assume equivalence between the two options.. Daily ICS was superior to intermittent ICS in several indicators of lung function, airway inflammation, asthma control and reliever use. Both treatments appeared safe, but a modest growth suppression was associated with daily, compared to intermittent, inhaled budesonide and beclomethasone. Clinicians should carefully weigh the potential benefits and harm of each treatment option, taking into account the unknown long-term (> one year) impact of intermittent therapy on lung growth and lung function decline.

Asthma in a primary health care center serving a poor population: a descriptive and interventional study

Asthma is a common chronic disease. Due to difficulties in accessibility to the health care system, asthma affects severely to minorities. This study's objective is to describe the morbidity of asthma on a poor population and its modification after abolishing assistance barriers.

Thirty-four asthma camps were carried out between May 2004 and May 2007. Patients' socioeconomic conditions, asthma history, and symptoms in the last month were determined during the camps. Patients received free medication and were invited to come to follow-up. Fifty-six children younger than 12 years old and 53 adults with persistent asthma were evaluated in 783 visits. The mean monthly income per capita was US $28.57.

At baseline, 50% of children and 34.5% of adults received inhaled corticosteroids. After intervention, 92.7% children and 98.1% adults received inhaled corticosteroids. Treatment was associated with a significant reduction of daytime and nighttime symptoms, absences to school or work, and emergency room visits and admissions. Patients referred less interference and more control of their disease in their everyday life.

Our results suggest that this population receives an insufficient treatment of its asthma severity. For such population, moving specialized assistance to the primary health care center resulted in a better control of their illness.

Compared to the daily ICS group, the intermittent ICS group displayed a smaller improvement in change from baseline peak expiratory flow rate (PEFR) by 2.56% (95% CI -4.49% to -0.63%), fewer symptom-free days (standardised mean difference (SMD) -0.15 (95% CI -0.28 to -0.03), fewer asthma control days -9% (95% CI -14% to -4%), more use of rescue β(2)-agonists by 0.12 puffs/day (95% CI 0 to 0.23) and a greater increase from baseline in exhaled nitric oxide of 16.80 parts per billion (95% CI 11.95 to 21.64). There was no significant group difference in forced expiratory volume in one second (FEV(1)), quality of life, airway hyper-reactivity, adverse effects, hospitalisations, emergency department visits or withdrawals. In paediatric trials, intermittent ICS (budesonide and beclomethasone) were associated with greater growth by 0.41 cm change from baseline (532 children; 95% CI 0.13 to 0.69) compared to daily treatment.

AUTHORS' CONCLUSIONS

In children and adults with persistent asthma and in preschool children suspected of persistent asthma, intermittent and daily ICS strategies did not significantly differ in the use of rescue oral corticosteroids and the rate of severe adverse health events, neither did they reach equivalence. Daily ICS was superior to intermittent ICS in several indicators of lung function, airway inflammation, asthma control and reliever use. Both treatments appeared safe, but a modest growth suppression was associated with daily, compared to intermittent, inhaled budesonide and beclomethasone. The clinician should carefully weigh the potential benefits and harm of each treatment option, taking into account the unknown long-term (> one year) impact of intermittent therapy on lung growth and lung function decline.

Home/social environment and asthma profiles in a vulnerable community from Caracas: lessons for urban Venezuela?

BACKGROUND

Asthma is a significant public health problem in Venezuela affecting the predominantly urban and poor majority of the population. Information regarding home and the social environment, key elements in asthma, is found to be deficient in these deprived socioeconomic sectors. This study was carried out to depict a life with asthma in this context which has been served over the years by a National Asthma Control Program.

METHODS

A survey of families residing in a socioeconomically deprived community of Caracas was carried out with the assumption that this community reflects the image of a life with asthma emanating from our deprived urban areas. Home physical settings were inspected for the following items: moldy walls, floors, ceilings, windows, sewage, garbage disposal, running water, plumbing, electricity, telephone, construction debris, furniture, bathrooms, food storage, and home appliances. In addition, we also gathered information regarding smoking habits, fumes exposure, pets and/or animals, and sighting of roaches and/or rodents. The presence of people with asthma was observed and their status of control was assessed through the asthma control test (ACT). Comparisons were made between families with asthmatics and those without asthmatics.

RESULTS

Randomly, 242 of 750 families (32.26%) were surveyed, with "head of family" providing information (75.6%) on most occasions. No significant association was found with respect to the previously explored items in those families with or without the presence of asthmatics. Medically diagnosed asthma was found in 14.91%, with ACT scores of <19 points in two-thirds of these adults and asthmatic children. Asthmatics reported symptoms occurring mostly during the night and an almost exclusive use of rescue medications. Families provided most treatments and children preferred to use the oral route for control medications. Significant work and school absenteeism were detected in more than 50% of these asthmatics.

CONCLUSIONS

No physical home environmental/risk factors turned out to be significantly associated with families reporting the presence of asthmatics. The high impact of asthma found in this Caracas slum underscores the realities of Venezuela's impoverished urban majority. To properly address this important challenge, our National Asthma Control Program needs to be reassessed.

The association of overweight and obesity with spirometric values in minority children referred for asthma evaluation

BACKGROUND

Overweight, obesity, and asthma are more prevalent in minority children; yet, the association of overweight and obesity with spirometric values in asthmatic minorities is not well characterized.

OBJECTIVE

To study the relationship between weight, ethnicity, and spirometric values in children referred for asthma evaluation to a large inner-city hospital in Bronx, NY.

METHODS

Retrospective review of spirometry done at the first pulmonary clinic visit of 980 asthmatic children, aged 7-20 years, was conducted. Linear regression analysis was performed to elucidate the association of overweight and obesity with pulmonary function among Whites, African Americans, and Hispanics compared with their normal weight counterparts.

RESULTS

More African Americans (58%) and Hispanics (65.4%) were overweight and obese than Whites (51.2%) (p < .05). Compared with their normal weight counterparts, percent forced expiratory volume in the 1st second (FEV(1))/forced vital capacity (FVC) ratio was lower in both overweight and obese African Americans (2.99%, p < .05 and 3.56%, p < .01, respectively) and Hispanics (2.64%, p < .05 and 2.36%, p < .05, respectively); these differences were found in obese (3.73%, p < .05) but not in overweight (0.68%, p = .7) Whites.

CONCLUSIONS

FEV(1)/FVC ratio was lower in both overweight and obese African American and Hispanic children, while this association was present only among obese Whites compared with their normal weight counterparts. These results suggest that spirometric measures of lower airway obstruction decrease with smaller weight increments in minority children when compared with White children. In the context of the higher prevalence of overweight and obesity among African Americans and Hispanics, our findings offer one potential explanation for increased asthma among minority children.

Understanding sibilancias (wheezing) among Mexican American parents

BACKGROUND

Asthma is one of the most common pediatric chronic diseases in the United States; however, prevalence varies across Latino ethnicities, such as Mexican Americans (MAs). Linguistic and cultural issues may contribute to difficulties in diagnosis.

METHODS

We conducted a qualitative study to assess the comprehension of common words used in a validated asthma questionnaire. The study sample consisted of 40 MA Spanish-speaking parents of 2- to 18-year-old children, with and without asthma, at a community health clinic.

RESULTS

Regardless of their child's asthma status, the majority of parents (12 [80%] with non-asthmatic children; 16 [64%] with asthmatic children) did not understand common Spanish words used in clinical settings to identify asthma (e.g., wheezing and whistling). Instead, parents used physical symptoms and sounds to describe asthma.

CONCLUSION

This exploratory study demonstrates MA parents' limited comprehension of common words used in clinical settings to identify asthma. Future research should examine tools that incorporate visual and auditory descriptions of asthma.

Low rates of controller medication initiation and outpatient follow-up after emergency department visits for asthma

OBJECTIVE

To determine what proportion of patients who are seen in an emergency department (ED) for asthma receive inhaled corticosteroids or attend follow-up appointments.

STUDY DESIGN

This was a retrospective cohort study of 2007-2009 South Carolina Medicaid data. Enrollees aged 2-18 years who had an ED visit for asthma were included. Patients admitted for asthma or with an inhaled corticosteroid claim in the 2 months before the month of the ED visit were excluded. Covariates were sex, race, age, rural residence, and asthma severity. Outcome measures were a prescription for an inhaled corticosteroid filled within the 2 months after the ED visit and attendance at a follow-up appointment within the 2 months after the ED visit.

RESULTS

A total of 3435 patients were included. Out of the study cohort, 57% were male, 76% were of a minority race/ethnicity, 69% lived in an urban areas, 18% had inhaled corticosteroid use, and 12% completed follow-up. Multivariate analyses demonstrated that patients with severe asthma were more likely to receive an inhaled corticosteroid (OR, 2.9; 95% CI, 2.3-3.7) and attend a follow-up appointment (OR, 2.0; 95% CI, 1.5-2.6). Patients aged 2-6 years and those aged >12 years were less likely to attend follow-up (OR, 0.71; 95% CI, 0.56-0.90 and OR, 0.62; 95% CI, 0.47-0.83, respectively) (all models P < .0001).

CONCLUSION

Children with asthma seen in the ED have low rates of inhaled corticosteroid use and outpatient follow-up. This indicates a need for further interventions to increase the use of inhaled corticosteroids in response to ED visits.

Trends in preventive asthma medication use among children and adolescents, 1988-2008

OBJECTIVE

To examine trends in preventive asthma medication (PAM) use among children with current asthma in the United States from 1988 to 2008.

METHODS

We performed a cross-sectional analysis of PAM use among 2499 children aged 1 to 19 years with current asthma using nationally representative data from the National Health and Nutrition Examination Survey (NHANES) during 3 time periods: 1988-1994, 1999-2002, and 2005-2008. PAMs included inhaled corticosteroids, leukotriene receptor antagonists, long-acting β-agonists, mast-cell stabilizers, and methylxanthines.

RESULTS

Among children with current asthma, there was an increase in the use of PAMs from 17.8% (SE: 3.3) in 1988-1994 to 34.9% (SE: 3.3) in 2005-2008 (P < .001 for trend). Adjusting for age, gender, race/ethnicity, and health insurance status, the odds of PAM use were higher in 2005-2008 compared with 1988-1994 (adjusted odds ratio [aOR] = 2.6; 95% confidence interval [CI]: 1.5-4.5). A multivariate analysis, combining all 3 time periods, showed lower use of PAMs among non-Hispanic black (aOR = 0.5 [95% CI: 0.4-0.7]) and Mexican American (aOR = 0.6 [95% CI: 0.4-0.9]) children compared to non-Hispanic white children. PAM use was also lower in 12 to 19 year olds compared with 1 to 5 year olds and also in children who did not have health insurance compared with those who did.

CONCLUSIONS

Between 1988 and 2008, the use of PAM increased among children with current asthma. Non-Hispanic black and Mexican American children, adolescents aged 12 to 19 years, and uninsured children with current asthma had lower use of PAM.

Asthma and the achievement gap among urban minority youth

OBJECTIVES

To outline the prevalence and disparities of asthma among school-aged urban minority youth, causal pathways through which poorly controlled asthma adversely affects academic achievement, and proven or promising approaches for schools to address these problems.

METHODS

Literature review.

RESULTS

Asthma is the most common chronic disease affecting youth in the United States; almost 10 million youth under 18 (14%) have received a diagnosis and 6.8 million (9%) have active asthma. Average annual prevalence estimates were approximately 45% higher for Black versus White children (12.8% vs. 8.8%), as were average annual estimates of asthma attacks (8.4% vs. 5.8%). Urban minority youth have highly elevated prevalence of poorly controlled asthma as evidenced by overuse of emergency departments and under-use of efficacious medications. Poorly controlled asthma has functional consequences on cognition, connectedness with school, and absenteeism. Exemplary asthma programs include management and support systems, school health and mental health services, asthma education, healthy school environments, physical education and activity, and coordination of school, family, and community efforts.

CONCLUSIONS

Asthma and, more importantly, poorly controlled asthma are highly and disproportionately prevalent among school-aged urban minority youth, has a negative impact on academic achievement through its effects on cognition, school connectedness, and absenteeism, and effective practices are available for schools to address this problem. To reduce the adverse effects of poorly controlled asthma on learning, a multifaceted approach to asthma control and prevention in which schools can and must play a central role is essential.

Improving asthma care for African American children by increasing national asthma guideline adherence

INTRODUCTION

Children, particularly African American children, bear a disproportionate burden of asthma and are at highest risk for associated morbidity and mortality. The under-utilization of the National Asthma Education and Prevention Program (NAEPP) guidelines across all demographics and the under use of inhaled corticosteroids (ICS) as controller therapy in these children are well-documented. The primary aim of this study was to increase health care provider (HCP) adherence to the NAEPP guidelines by means of a guideline reminder tool, the Multi-colored Simplified Asthma Guideline Reminder, consequently increasing the prescription of ICS in this population.

METHOD

This study had a pre-experimental design with descriptive analysis.

RESULTS

The Multi-colored Simplified Asthma Guideline Reminder was effective in increasing HCP adherence to the NAEPP guidelines as evidenced by increased use of ICS as controller therapy.

DISCUSSION

Despite the increasing prevalence and burden of asthma in African American children, the associated prescriptive use of ICS has not increased substantially in the past decade. The greatest obstacle in the scope of improving asthma outcomes is the underuse of ICS by HCPs.

Under-utilization of controller medications and poor follow-up rates among hospitalized asthma patients

OBJECTIVE

Recommended preventive care following an asthma admission includes prescribing controller medications and encouraging outpatient follow-up. We sought to determine (1) the proportion of patients who receive controller medications or attend follow-up after asthma admission and (2) what factors predict these outcomes.

METHODS

South Carolina Medicaid data from 2007-2009 were analyzed. Patients who were included were 2 to 18 years old, and had at least one admission for asthma. Variables examined were: age, gender, race, and rural location. Outcome variables were controller medication prescription and follow-up appointment. Any claim for an inhaled corticosteroid (ICS) or ICS/long-acting beta-agonist in the 2 months after admission was considered appropriate. Any outpatient visit for asthma in the 2 months after admission was considered appropriate. Bivariate analyses used chi-square tests. Logistic regression models identified factors that predict controller medications and follow-up.

RESULTS

Five hundred five patients were included, of whom 60% were male, 79% minority race/ethnicity, and 58% urban. Rates of receiving controller medications and attending follow-up appointments were low, and an even lower proportion received both. Overall, 52% received a controller medication, 49% attended follow-up, and 32% had both. Multivariable analyses demonstrated that patients not of minority race or ethnicity were more likely to receive controller medications (odds ratio, 1.7; 95% confidence interval, 1.1-2.6).

CONCLUSIONS

Patients with asthma admitted for acute exacerbations in South Carolina have low rates of controller medication initiation and follow-up attendance. Minority race/ethnicity patients are less likely to receive controller medications. To decrease rates of future exacerbations, inpatient providers must improve the rates of preventive care delivery in the acute care setting with a focus on racial/ethnic minority populations.

A simulation model approach to analysis of the business case for eliminating health care disparities

BACKGROUND

Purchasers can play an important role in eliminating racial and ethnic disparities in health care. A need exists to develop a compelling "business case" from the employer perspective to put, and keep, the issue of racial/ethnic disparities in health care on the quality improvement agenda for health plans and providers.

METHODS

To illustrate a method for calculating an employer business case for disparity reduction and to compare the business case in two clinical areas, we conducted analyses of the direct (medical care costs paid by employers) and indirect (absenteeism, productivity) effects of eliminating known racial/ethnic disparities in mammography screening and appropriate medication use for patients with asthma. We used Markov simulation models to estimate the consequences, for defined populations of African-American employees or health plan members, of a 10% increase in HEDIS mammography rates or a 10% increase in appropriate medication use among either adults or children/adolescents with asthma.

RESULTS

The savings per employed African-American woman aged 50-65 associated with a 10% increase in HEDIS mammography rate, from direct medical expenses and indirect costs (absenteeism, productivity) combined, was $50. The findings for asthma were more favorable from an employer point of view at approximately $1,660 per person if raising medication adherence rates in African-American employees or dependents by 10%.

CONCLUSIONS

For the employer business case, both clinical scenarios modeled showed positive results. There is a greater potential financial gain related to eliminating a disparity in asthma medications than there is for eliminating a disparity in mammography rates.

The Breathmobile program: a good investment for underserved children with asthma

BACKGROUND

The Breathmobile, a specialty-based mobile asthma clinic, provides free care to underserved children. The cost of symptom-free day (SFD) improvement in this population has not been previously reported.

OBJECTIVE

To examine the clinical impact and cost-effectiveness of the Baltimore Breathmobile.

METHODS

Existing computerized data were analyzed for Breathmobile patient visits between 2002 and 2007. All SFDs were calculated, and direct medical cost savings attributable to decreased emergency department visits and hospitalizations (after program utilization vs the previous year) were compared with annual operating costs. Incremental cost-effectiveness ratios were determined by calculating the incremental costs of Breathmobile care per additional SFD gained per child per year.

RESULTS

The analysis included 255 patients enrolled in the program for at least 1 year. Most participants were black (93.3%), and 54.9% were male. At baseline, patients reported a mean (SD) of 199 (118) SFDs in the year before enrollment. After 1 year in the program, patients had a mean (SD) improvement of 44 (9) SFDs. The program resulted in overall cost savings of $79.43 per SFD gained, with greater cost savings for children aged 5 to 11 years (-$116.84 per SFD gained) and those with intermittent asthma (-$126.71 per SFD gained).

CONCLUSIONS

The Baltimore Breathmobile program has demonstrated significant improvement in SFDs, with direct medical cost savings of the program outweighing the operational costs. These data support the need to continue to sustain and expand Breathmobile programs for children at high risk for asthma exacerbations and to conduct a randomized clinical trial to estimate the cost-effectiveness of the Breathmobile.

Patient And phaRmacist Telephonic Encounters (PARTE) in an underserved rural population with asthma: methods and rationale

PURPOSE

Methods used to deliver and test a pharmacy-based asthma care telephonic service for an underserved, rural patient population are described.

SUMMARY

In a randomized controlled trial (RCT), the Patient And phaRmacist Telephonic Encounters (PARTE) project is assessing the feasibility, acceptability, and preliminary impact of providing pharmacy-based asthma care service telephonically. The target audience is a low income patient population across a large geographic area served by a federally qualified community health center. Ninety-eight participants have been randomized to either standard care or the intervention group who received consultation and direct feedback from pharmacists via telephone regarding their asthma self-management and medication use. Pharmacists used a counseling framework that incorporates the Indian Health Services 3 Prime Questions and the RIM Technique (Recognition, Identification, and Management) for managing medication use problems. Pharmacists encouraged patients to be active partners in the decision-making process to identify and address the underlying cause of medication use problems. Uniquely, this trial collected process and summative data using qualitative and quantitative approaches. Pharmacists' training, the fidelity and quality of pharmacists' service delivery, and short term patient outcomes are being evaluated. This evaluation will improve our ability to address research challenges and intervention barriers, refine staff training, explore patient perspectives, and evaluate measures' power to provide preliminary patient outcome findings.

CONCLUSION

A mixed method evaluation of a structured pharmacist intervention has the potential to offer insights regarding staff training, service fidelity and short term outcomes using quantitative and qualitative data in an RCT. Results will provide evidence regarding the feasibility and quality of carrying out the study and service delivery from the multiple perspectives of participants, clinicians, and researchers.

Relationship of medical home quality with school engagement and after-school participation among children with asthma

OBJECTIVES

To examine the relationship between medical home quality and measures of daily life experiences among children with asthma.

METHODS

A nationally representative sample of children from the 2007 National Survey of Children's Health (NSCH), aged 6-17 years (n = 6357), who have asthma was used to assess the relationship of a quality medical home and its features with their daily life experiences. Five medical home features - access, continuity, comprehensiveness, family-centered care, and coordination of care - were examined individually and in total in relation to measures of school engagement (missed school days, parents contacted about problems with the child, repeating a grade since kindergarten) and after-school activity participation (physical activity, sports participation, and community service or volunteer work).

RESULTS

Before and after adjustment for personal characteristics, health insurance status, family environment, neighborhood variables, and asthma severity, total medical home score was associated with more days exercised [beta (B) = 0.10, p < .05] and a greater likelihood of having performed community service or volunteer work [odds ratio (OR) = 1.16, CI: 1.02-1.31]. Additionally, the medical home features of access, comprehensiveness, and family-centered care remained favorably associated with three of the six measures of school engagement and after-school activity participation, even after adjustment.

CONCLUSION

Medical home quality - particularly the features of access, comprehensiveness, and family-centered care - is positively associated with the daily life experiences of children with asthma. Working to enhance these aspects of primary care might be one place to start in improving the management of children's chronic conditions and their quality of life.

Younger asthmatics are less likely to receive inhaled corticosteroids and asthma education after admission for exacerbation

BACKGROUND

Recommended care prior to discharge from an asthma hospitalization includes prescribing controller medications, providing asthma education, and scheduling a follow-up appointment.

OBJECTIVE

To identify factors associated with receipt of recommended preventive care among children hospitalized for asthma.

METHODS

Retrospective chart review of patients 2-18 years with primary diagnosis of asthma admitted to MUSC Children's Hospital in 2005. Gender, race, age (2-6 yrs v. 7-18 yrs), primary payer, and season of admission were recorded. Outcome variables were: prescription for inhaled corticosteroids (ICS), asthma education, and scheduling a follow-up appointment.

RESULTS

Of the 146 subjects analyzed, 59% were male, 69% non-white, 64% 2-6 years old, 73% Medicaid/other, and 66% were admitted between Oct-March. 73% were prescribed ICS, 71% got asthma education, and 66% had a follow-up appointment scheduled. Bivariate analyses showed that 2-6 year olds were less likely to get ICS (65% v. 88% p < .01) and asthma education (64% v. 84% p < .05). Multivariable analyses demonstrated that younger children were less likely to get ICS (OR= 0.27 95% CI 0.10 - 0.70), younger children were less likely to get asthma education (OR 0.29 95% CI 0.11- 0.74), and commercial payer patients were less likely to get follow-up appointments scheduled (OR 0.39 95% CI 0.18 -0.87) (all models, p < .05).

CONCLUSIONS

Among children hospitalized for asthma at our institution, younger patients are significantly less likely to receive inhaled steroids and asthma education. Targeting younger asthmatics may be a way to efficiently and effectively improve delivery of recommended preventive care in the hospital.

Using action research to implement an integrated pediatric asthma case management and eHealth intervention for low-income families

Asthma case management and education programs improve pediatric asthma outcomes, but designing rigorous randomized controlled studies that accurately measure effects while encouraging parent participation is challenging. This is especially so for low-income African American families, who face significantly more severe asthma and social stress than their middle-class counterparts. Action research can help health education researchers negotiate between the elegant and complex designs favored by scientists with the real-life challenges of recruitment, implementation, and retention. This article discusses how a multidisciplinary team uses action research concepts to continuously adjust originally proposed protocols through the planning and implementation phases to encourage participation in a year-long randomized controlled trial of a program that combines telephone asthma case management and comprehensive online asthma education. As a result of these efforts, a higher proportion of low-income African American families are recruited into the study than originally proposed.

Determining an association between having a medical home and uncontrolled asthma in US school-aged children: a population-based study using data from the National Survey of Children's Health

INTRODUCTION

The American Academy of Pediatrics and the American Academy of Family Physicians believe that infants, children, and adolescents benefit from having a medical home, characterized by accessible, continuous, comprehensive, family-centered, coordinated, compassionate, and culturally effective care. Several studies suggest that patients with asthma benefit from having a medical home. However, no national study has been conducted examining the relationships between having a medical home and asthma control in school-aged children with asthma. The purpose of this study was to examine the hypothesis that having an adequate medical home is protective against uncontrolled asthma in children.

METHODS

To test this hypothesis, cross-sectional data from the 2003-2004 National Survey of Children's Health were analyzed. Analyses entailed creating the variables "medical home" as well as "uncontrolled asthma" from multiple variables. Multivariate analysis was performed using children with uncontrolled asthma as the dependent variable.

RESULTS

The logistic regression model performed yielded that school-aged children with uncontrolled asthma were more likely to: speak a primary language other than English (OR, 1.069; 95% CI, 1.045-1.093); live in households with incomes<100% of the federal poverty level (FPL) (OR, 1.826; 95% CI, 1.810-1.842); not have health insurance (OR, 2.296; 95% CI, 2.263-2.330); live in rural rather than metropolitan areas (OR, 1.275; 95% CI, 1.262-1.287); and be non-Caucasian (OR, 2.067; 95% CI, 2.050-2.085). Multivariate analysis also yielded that children with uncontrolled asthma were more likely to have a medical home (OR, 1.138; 95% CI, 1.128-1.148).

CONCLUSIONS

After controlling for possible confounding variables, this study did not detect an association between having a medical home and asthma control for children with asthma aged 5 to 17 years. Additional research should examine the relationship between variables, such as poverty, place of residence, health insurance status, and the medical home, not only in the instance of uncontrolled asthma, but for other childhood health conditions.

Cultural-related, contextual, and asthma-specific risks associated with asthma morbidity in urban children

The objective of this study was to examine associations between specific dimensions of the multi-dimensional cumulative risk index (CRI) and asthma morbidity in urban, school-aged children from African American, Latino and Non-Latino White backgrounds. An additional goal of the study was to identify the proportion of families that qualify for high-risk status on each dimension of the CRI by ethnic group. A total of 264 children with asthma, ages 7-15 (40% female; 76% ethnic minority) and their primary caregivers completed interview-based questionnaires assessing cultural, contextual, and asthma-specific risks that can impact asthma morbidity. Higher levels of asthma-related risks were associated with more functional morbidity for all groups of children, despite ethnic group background. Contextual and cultural risk dimensions contributed to more morbidity for African-American and Latino children. Analyses by Latino ethnic subgroup revealed that contextual and cultural risks are significantly related to more functional morbidity for Puerto Rican children compared to Dominican children. Findings suggest which type of risks may more meaningfully contribute to variations in asthma morbidity for children from specific ethnic groups. These results can inform culturally sensitive clinical interventions for urban children with asthma whose health outcomes lag far behind their non-Latino White counterparts.

Evaluation of diagnostic criteria for severe asthma described in a public health directive regulating the free distribution of medications for the maintenance treatment of asthma

OBJECTIVE

To evaluate the capacity of the criteria described in Complementary Directive SAS/MS 12, issued on November 12, 2002, to identify patients with severe asthma, describing and comparing clinical, functional and treatment data of such patients.

METHODS

This was a nested case-control study using a structured database for adult asthma outpatients. We defined cases as asthma patients who met the inclusion criteria described in the directive, defining controls as those who did not. We collected and compared data related to the following: demographic characteristics; history of asthma; medications in use; comorbidities; history of tobacco use; number of exacerbations within the last 12 months, asthma-related hospitalizations and intensive care unit admissions within the last 12 months; spirometry; and sputum cytology.

RESULTS

The case and control groups consisted of 29 and 31 patients, respectively. The number of asthma exacerbations and emergence room visits within the last 12 months, as well as the number of patients that received at least one pulse of oral corticosteroids, was significantly higher in the case group than in the control group. In addition, prebronchodilator FVC was lower among the cases than among the controls. Furthermore, cytology revealed that eosinophil counts were significantly higher in the induced sputum of cases than in that of controls.

CONCLUSIONS

The criteria described in the directive are suited to stratifying patients with severe asthma.

Life events, chronic stressors, and depressive symptoms in low-income urban mothers with asthmatic children

OBJECTIVE

This secondary data analysis study examines the relationship between maternal sociodemographic variables, life events, chronic stressors, including asthma control and management and environmental stressors, and maternal depression.

DESIGN

Cross-sectional descriptive design study consisting of baseline data from participants enrolled in a randomized asthma communication educational intervention trial.

SAMPLE

201 mothers of children with asthma (ages 6-12), recruited from community pediatric practices and emergency departments of 2 urban university hospitals.

MEASUREMENT

Life events were measured using standardized items. Chronic stressors were measured using items from the International Asthma and Allergies in Childhood study and maternal and child exposure to violence. Depressive symptoms were assessed with the Center for Epidemiologic Studies-Depression scale.

RESULTS

Close to 25% of the mothers had high depressive symptoms. In separate multiple logistic regression models, education (adjusted odds ratio [AOR]=2.62; 95% confidence interval [CI]=1.07, 6.39) or unemployment (AOR=2.38; 95% CI=1.16, 4.90) and the use of quick relief medications (AOR=2.74; 95% CI=1.33, 5.66) for asthma were positively associated with depressive symptoms.

CONCLUSIONS

Implications include the need to assess maternal depressive symptoms of mothers of children with asthma, in order to improve asthma management for low-income urban children.

Barriers to asthma management among urban families: caregiver and child perspectives

OBJECTIVE

Asthma is one of the most common chronic diseases of childhood. Those particularly affected are young, poor, African American children. Moreover, rates of emergency department visits, hospitalizations, and mortality are substantially higher for black children. Despite the ample published research on asthma prevalence and asthma management interventions, there is little research available on barriers to asthma care among urban, low-income families as perceived by children with asthma and their caregivers.

METHODS

This qualitative study analyzed data from five focus groups conducted with 28 participants in metropolitan Atlanta.

RESULTS

This study found caregiver and child health beliefs and perceptions concerning the use of daily controller medications to be a significant barrier to asthma care and proper self-management at home and at school. Barriers to environmental control consisted mostly of financial constraints, which made residential environmental remediation activities difficult to implement. Psychological distress was prevalent among both children and caregivers, which demonstrated the burden associated with managing a chronic illness.

CONCLUSION

Families in urban, low-income communities require asthma management interventions tailored to their specific characteristics, barriers, and challenges. Our findings can be used to inform and enhance asthma management interventions for urban families with children with asthma.

Outpatient management of asthma in children age 5-11 years: guidelines for practice

PURPOSE

To increase awareness among nurse practitioners (NPs) regarding diagnostic and treatment guidelines for asthma for the 5-11 year age group recently updated by the National Asthma Education Prevention Program-Expert Panel 3 (NAEPP-EPR3).

DATA SOURCES

NAEPP-EPR3 guidelines for the diagnosis and management of asthma released from the National Heart, Lung, and Blood Institute in August 2007, selected clinical trials, meta-analyses, and clinical reviews.

CONCLUSIONS

Recent research has revealed that children suffering from asthma in the United States are underdiagnosed and their asthma is poorly controlled. Compelling evidence supports that children classified as having persistent asthma following NAEPP-EPR3 guidelines benefit from daily inhaled corticosteroid therapy, yet many are misclassified and undertreated.

IMPLICATIONS FOR PRACTICE

With application of current guidelines from NAEPP-EPR3, NPs can more effectively assess, diagnose, treat, and foster a collaborative self-management plan for children age 5-11 years. These interventions will result in an improved quality of life and decreased health risks for this young population.

Disparities in the national prevalence of a quality medical home for children with asthma

OBJECTIVE

The aim of this study was to examine sociodemographic disparities in having a quality medical home among a nationally representative sample of children with asthma.

METHODS

The study examined data from the 2003 National Survey of Children's Health to identify 8360 children aged 2-17 years with asthma. Risk factors including nonwhite race/ethnicity, income <200% of the federal poverty level (FPL), uninsured, parent education less than high school, and non-English language, were examined individually and as a profile of risk in relation to a quality medical home. Fourteen questions were used to measure 5 medical home features: access, continuity, comprehensiveness, family-centered care, and coordination. A poorer quality medical home was defined as < or =66 on a 100-point scale-corresponding to the feature being present less than "usually"-for each feature and for an overall score.

RESULTS

Before and after adjustment for demographics and asthma difficulties, most risks except less than high school parent education were related to a poorer quality medical home. Uninsured children had the highest odds of a poorer quality medical home overall (adjusted odds ratio [OR] 5.19, 95% confidence interval [CI] 3.52-7.65) and across most features, except for coordination. Children experiencing 3+ risks had 8.56 times the odds of a poorer quality medical home overall (95% CI 4.95-14.78) versus zero risks.

CONCLUSIONS

This study demonstrates large national disparities in a quality medical home for children with asthma. That disparities were most prevalent for the uninsured (insurance being a modifiable risk factor) suggests increasing coverage is essential to assuring that children obtain a quality medical home.

Quality of care for childhood asthma: estimating impact and implications

We conducted a review of 164 relevant publications to consolidate the evidence on gaps in the quality of asthma care, the impact of those gaps, and the costs and benefits of closing those gaps. Researchers used a wide variety of definitions for measures of quality asthma care, clinical and utilization end points, and disease severity. Gaps in care were most evident for pharmacologic treatment, particularly the underuse of inhaled corticosteroids, with median usage rates of 40%; however, in studies with large proportions of black subjects, the inhaled corticosteroid usage rate was only 32%, compared with 51% for nonminority populations. Studies on outcomes focused on emergency department visits, hospital admissions, and missed school days. Because only 6 studies included information on the costs of improving asthma care, no consensus estimates of the cost/benefit ratio for better asthma care could be derived. There was insufficient evidence in the literature for assessment of the impact of gaps in care and the costs of closing those gaps. More economic evaluations of the impact of gaps in asthma care and of interventions to improve asthma control are needed. Future research on gaps in asthma care and their impact must use standardized definitions for key variables such as disease severity and care utilization to allow comparisons across studies and building of an evidence base that is convincing for policy makers and purchasers of care.

Recommendations for treatment of intermittent mild persistent asthma in children and adolescents

Many parents and caretakers of children and adolescents with mild persistent asthma (MPA) do not follow proposed guidelines, namely the daily and continuous administration of inhaled corticosteroids (ICS). Instead, parents and caretakers tend to use ICS and bronchodilators intermittently for short periods and restart such therapy only when symptoms reappear. It is our opinion that intermittent treatment of MPA in children and adolescents might achieve the same level of asthma control as has been achieved in adults. We propose, therefore, that after an initial period of stabilization with age-appropriate doses of oral glucocorticoids or high-dose ICS and short-acting beta-2 agonists (SABA), caretakers can stop treatment once there are no longer signs or symptoms of asthma. When asthmatic symptoms recur, treatment should be restarted with ICS and SABA, or oral corticosteroids if the exacerbation is severe. The perception of developing asthma symptoms remains an unsolved problem. Based on our clinical experience in children and adolescents with asthma, we list a number of signs and symptoms that precede an exacerbation of asthma, allowing for an early re-introduction of treatment to prevent an exacerbation.

Racial/ethnic differences in asthma-related emergency department visits and hospitalizations among children with wheeze in Buffalo, New York

This study examined whether racial/ethnic minority (i.e., Black, Hispanic) children with wheeze have a higher proportion of urgent care use (i.e., emergency department visit or hospitalization) for asthma compared to their White counterparts. We also assessed the contribution of disease severity and sociodemographic, access to care, and home environmental risk factors to racial/ethnic differences in utilization. A cross-sectional study was conducted among children aged 0 to 17 in Buffalo, New York. We compared rates of urgent care visits and physician-diagnosed asthma among racial/ethnic groups, and conducted race/ethnicity stratified analyses by number of symptoms, asthma severity, insurance types, and medical care access. Multivariate regression analyses were used to examine differences in urgent care use by race/ethnicity after controlling for multiple confounders and to identify factors associated with urgent care utilization by race/ethnicity. Asthma symptom severity was the primary factor contributing to urgent care use in this population, followed by race/ethnicity and Medicaid enrollment. Minority children with wheeze were nearly twice as likely as Whites to have used urgent care for asthma, after controlling for disease severity, access to care, and environmental factors. Not having a home remedy in place for asthma or reporting trouble getting care also contributed to the greater use of urgent care resources among minority children. Minority children still had a significantly higher proportion of urgent care use for acute asthma care compared to Whites, even after controlling for multiple risk factors. Disease severity and inadequate access to medical care may partially explain higher rates among minority children. Future studies should examine racial/ethnic differences in other factors potentially associated with urgent care use, including asthma management and use of routine asthma care.

Prevalence and impact of nighttime symptoms in adults and children with asthma: a survey

BACKGROUND

The frequency of nighttime asthma symptoms is an important measure of asthma severity. This study was designed to determine the prevalence of daytime and nighttime symptoms in adults and children with asthma and to evaluate the impact of nighttime symptoms on sleep and daytime activities.

METHODS

An online survey was conducted among adults (> 18 years) and mothers of children aged 2 to 17 years with asthma. The survey included questions on daytime and nighttime asthma symptoms and asthma controller medication. Invitations to complete the survey were sent to 6349 members of a global opinion panel who were identified as having asthma. Data collection was from April to May 2005.

RESULTS

A total of 1600 invited panelists responded to the survey. Overall, 61% of participants reported nighttime asthma symptoms and 74% reported daytime asthma symptoms. Asthma-related sleep difficulties occurred approximately 4 times per week in adults and approximately 3 times per week in children. A significantly greater proportion of adults than children reported bothersome symptoms in the morning on awakening. Wheezing and difficulty breathing were reported in a greater proportion of adults, whereas coughing was reported in a greater proportion of children. A greater proportion of adults than children reported feelings of tiredness and impaired activity on days after experiencing nighttime symptoms. Absenteeism and lateness were more commonly reported by mothers of children with asthma than by other adults.

CONCLUSIONS

The prevalence of reported asthma symptoms, particularly nighttime symptoms, and the effects of nighttime symptoms on sleep and daytime activities indicates that survey participants had poorly controlled asthma.

Socioeconomic factors and asthma control in children

OBJECTIVES

The objective of this study was to evaluate the association between socioeconomic factors and asthma control in children, as defined by the Canadian Pediatric Asthma Consensus Guidelines.

PATIENTS AND METHODS

Cross-sectional data from a completed study of 879 asthmatic children between the ages of 1 and 18 residing in the Greater Toronto Area were used. The database included data on demographics, health status, asthma control, and health-related quality of life. Stepwise forward modeling multiple regression was used to investigate the impact of socioeconomic status on asthma control, based on six control parameters from the 2003 Canadian Pediatric Asthma Consensus Guidelines.

RESULTS

Only 11% of patients met the requirements for acceptable control, while 20% had intermediate control, and 69% had unacceptable asthma control. Children from families in lower income adequacy levels had poorer control.

CONCLUSIONS

Disparities in asthma control between children from families of different socio-economic strata persist, even with adjustment for utilization of primary care services and use of controller medications.

Using unannounced standardized patients to assess residents' competency in asthma severity classification

OBJECTIVE

The aim of this study was to test the hypothesis that an educational intervention would increase the competency of pediatric residents in classifying asthma severity as assessed using unannounced standardized patients (SPs).

METHODS

Six SPs were trained to represent mild-intermittent, mild-persistent, moderate-persistent, and severe-persistent asthma. Data from a control group were obtained in 2002-2003. In 2003-2004, after an intervention, data were collected from an intervention group. The intervention consisted of a didactic session and posting the criteria for asthma severity classification. During precepting, faculty obtained a commitment from residents (N = 12) regarding the severity classification. Faculty and residents were blinded to the presence of SPs. The assigned severity of each SP was used as the criterion standard. Residents' severity classification was compared with the criterion standard. To test whether competency improved postintervention, we compared residents' performance by using intervention group versus control group and within-subject control comparisons. Bivariate analyses tested differences in proportions of categorical variables.

RESULTS

Fifty resident-SP encounters were analyzed. The intervention group performed significantly better than controls at each level of training in identifying persistent asthma: postgraduate year 3 (PGY3, 100% vs 71%), PGY2 (71% vs 50%), and PGY1 (50% vs 43%). They also performed significantly better in determining subclassifications of persistent asthma: PGY3 (87% vs 40%), PGY2 (67% vs 33%), and PGY1 (50% vs 33%). All had P < .05. Similarly, for within-subject control comparison, residents performed significantly better postintervention at identification and subclassification of persistent asthma than did the same residents at baseline.

CONCLUSIONS

An educational intervention resulted in significant improvements in the competency of residents in asthma severity classification.

Patterns of concordance and non-concordance with clinician recommendations and parents' explanatory models in children with asthma

OBJECTIVE

Many children with asthma do not take medications as prescribed. We studied parents of children with asthma to define patterns of non-concordance between families' use of asthma controller medications and clinicians' recommendations, examine parents' explanatory models (EMs) of asthma, and describe relationships between patterns of non-concordance and EM.

METHODS

Qualitative study using semi-structured interviews with parents of children with persistent asthma. Grounded theory analysis identified recurrent themes and relationships between reported medication use, EMs, and other factors.

RESULTS

Twelve of the 37 parents reported non-concordance with providers' recommendations. Three types of non-concordance were identified: unintentional--parents believed they were following recommendations; unplanned--parents reported intending to give controller medications but could not; and intentional--parents stated giving medication was the wrong course of action. Analysis revealed two EMs of asthma: chronic--parents believed their child always has asthma; and intermittent--parents believed asthma was a problem their child sometimes developed.

CONCLUSIONS

Concordance or non-concordance with recommended use of medications were related to EM's and family context and took on three different patterns associated with medication underuse.

PRACTICE IMPLICATIONS

Efforts to reduce medication underuse in children with asthma may be optimized by identifying different types of non-concordance and tailoring interventions accordingly.
