Caregiver-physician medication concordance and undertreatment of asthma among inner-city children

Racial and Ethnic Disparities in All-Cause and Cause-Specific Mortality Among US Youth

Importance

Mortality rates in US youth have increased in recent years. An understanding of the role of racial and ethnic disparities in these increases is lacking.

Objective

To compare all-cause and cause-specific mortality trends and rates among youth with Hispanic ethnicity and non-Hispanic American Indian or Alaska Native, Asian or Pacific Islander, Black, and White race.

Design, Setting, and Participants

This cross-sectional study conducted temporal analysis (1999-2020) and comparison of aggregate mortality rates (2016-2020) for youth aged 1 to 19 years using US Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research database. Data were analyzed from June 30, 2023, to January 17, 2024.

Main Outcomes and Measures

Pooled, all-cause, and cause-specific mortality rates per 100 000 youth (hereinafter, per 100 000) for leading underlying causes of death were compared. Injuries were classified by mechanism and intent.

Results

Between 1999 and 2020, there were 491 680 deaths among US youth, including 8894 (1.8%) American Indian or Alaska Native, 14 507 (3.0%) Asian or Pacific Islander, 110 154 (22.4%) Black, 89 251 (18.2%) Hispanic, and 267 452 (54.4%) White youth. Between 2016 and 2020, pooled all-cause mortality rates were 48.79 per 100 000 (95% CI, 46.58-51.00) in American Indian or Alaska Native youth, 15.25 per 100 000 (95% CI, 14.75-15.76) in Asian or Pacific Islander youth, 42.33 per 100 000 (95% CI, 41.81-42.86) in Black youth, 21.48 per 100 000 (95% CI, 21.19-21.77) in Hispanic youth, and 24.07 per 100 000 (95% CI, 23.86-24.28) in White youth. All-cause mortality ratios compared with White youth were 2.03 (95% CI, 1.93-2.12) among American Indian or Alaska Native youth, 0.63 (95% CI, 0.61-0.66) among Asian or Pacific Islander youth, 1.76 (95% CI, 1.73-1.79) among Black youth, and 0.89 (95% CI, 0.88-0.91) among Hispanic youth. From 2016 to 2020, the homicide rate in Black youth was 12.81 (95% CI, 12.52-13.10) per 100 000, which was 10.20 (95% CI, 9.75-10.66) times that of White youth. The suicide rate for American Indian or Alaska Native youth was 11.37 (95% CI, 10.30-12.43) per 100 000, which was 2.60 (95% CI, 2.35-2.86) times that of White youth. The firearm mortality rate for Black youth was 12.88 (95% CI, 12.59-13.17) per 100 000, which was 4.14 (95% CI, 4.00-4.28) times that of White youth. American Indian or Alaska Native youth had a firearm mortality rate of 6.67 (95% CI, 5.85-7.49) per 100 000, which was 2.14 (95% CI, 1.88- 2.43) times that of White youth. Black youth had an asthma mortality rate of 1.10 (95% CI, 1.01-1.18) per 100 000, which was 7.80 (95% CI, 6.78-8.99) times that of White youth.

Conclusions and Relevance

In this study, racial and ethnic disparities were observed for almost all leading causes of injury and disease that were associated with recent increases in youth mortality rates. Addressing the increasing disparities affecting American Indian or Alaska Native and Black youth will require efforts to prevent homicide and suicide, especially those events involving firearms.

Guideline Alignment and Medication Concordance in COPD

BACKGROUND

Provider adherence to clinical treatment guidelines in COPD is low. However, for patients to receive guideline-aligned care, providers not only must prescribe guideline-aligned care, but also must communicate that regimen successfully to patients to ensure medication concordance. The rate of medication concordance between patients and providers and its impact on clinical management is unknown in COPD.

RESEARCH QUESTION

To examine rates of guideline alignment and medication concordance and to identify patient-level factors that place patients at risk for these types of poor disease management outcomes.

STUDY DESIGN AND METHODS

This study was a secondary data analysis of the Medication Adherence Research in COPD study (2017-2023). Participants were categorized into 2017 Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage. Medication regimens were classified as aligned or nonaligned with 2017 GOLD guidelines. Nonaligned regimens were stratified further into overuse and underuse categories. Medication concordance between provider-reported and participant-reported regimens was determined. Factors associated with guideline alignment and medication concordance were evaluated using logistic regression.

RESULTS

Of 191 participants, 51% of provider-reported regimens were guideline aligned, with 86% of nonaligned regimens reflecting overuse with an inhaled corticosteroid (ICS). Thirty-eight percent of participants reported different regimens than their providers, of which > 80% reflected participants not reporting medications their providers reported prescribing. Participants did not report long-acting muscarinic antagonists and long-acting beta-agonists at similar rates as ICSs. Greater symptom burden and absence of a pulmonologist on the care team were associated with both guideline misalignment and medication discordance. Cognitive impairment and Black race additionally were associated with medication discordance.

INTERPRETATION

Guideline misalignment and medication discordance were common and were driven by overuse of ICSs and unreported medications, respectively. The patient-level factors associated with medication discordance highlight the importance of improving patient-provider communication to improve clinical management in COPD.

Impact of socioeconomic factors on allergic diseases

Allergic and immunologic conditions, including asthma, food allergy, atopic dermatitis, and allergic rhinitis, are among the most common chronic conditions in children and adolescents that often last into adulthood. Although rare, inborn errors of immunity are life-altering and potentially fatal if unrecognized or untreated. Thus, allergic and immunologic conditions are both medical and public health issues that are profoundly affected by socioeconomic factors. Recently, studies have highlighted societal issues to evaluate factors at multiple levels that contribute to health inequities and the potential steps toward closing those gaps. Socioeconomic disparities can influence all aspects of care, including health care access and quality, diagnosis, management, education, and disease prevalence and outcomes. Ongoing research, engagement, and deliberate investment of resources by relevant stakeholders and advocacy approaches are needed to identify and address the impact of socioeconomics on health care disparities and outcomes among patients with allergic and immunologic diseases.

Health Disparities: Interventions for Pulmonary Disease - A Narrative Review

There is expansive literature documenting the presence of health disparities, but there are disproportionately few studies describing interventions to reduce disparity. In this narrative review, we categorize interventions to reduce health disparity in pulmonary disease within the US health care system to support future initiatives to reduce disparity. We identified 211 articles describing interventions to reduce disparity in pulmonary disease related to race, income, or sex. We grouped the studies into the following four categories: biologic, educational, behavioral, and structural. We identified the following five main themes: (1) there were few interventional trials compared with the breadth of studies describing health disparities, and trials involving patients with asthma who were Black, low income, and living in an urban setting were overrepresented; (2) race or socioeconomic status was not an effective marker of individual pharmacologic treatment response; (3) telehealth enabled scaling of care, but more work is needed to understand how to leverage telehealth to improve outcomes in marginalized communities; (4) future interventions must explicitly target societal drivers of disparity, rather than focusing on individual behavior alone; and (5) individual interventions will only be maximally effective when specifically tailored to local needs. Much work has been done to catalog health disparities in pulmonary disease. Notable gaps in the identified literature include few interventional trials, the need for research in diseases outside of asthma, the need for high quality effectiveness trials, and an understanding of how to implement proven interventions balancing fidelity to the original protocol and the need to adapt to local barriers to care.

Social determinants of health and asthma

PURPOSE OF REVIEW

Social determinants of health play a major role in healthcare utilization and outcomes in patients with asthma. Continuing to understand how these complex and interwoven relationships interact to impact patient care will be crucial to creating innovative programmes that address these disparities.

RECENT FINDINGS

The current literature continues to support the association of substandard housing, urban and rural neighbourhoods, and race/ethnicity with poor asthma outcomes. Targeted interventions with community health workers (CHWs), telemedicine and local environmental rectifications can help improve outcomes.

SUMMARY

The link between social determinants and poor asthma outcomes continues to be supported by recent literature. These factors are both nonmodifiable and consequences of institutionalized racist policies that require innovative ideas, technologic equity and funding for groups most at risk for poorer outcomes.

Environmental justice and allergic disease: A Work Group Report of the AAAAI Environmental Exposure and Respiratory Health Committee and the Diversity, Equity and Inclusion Committee

Environmental justice is the concept that all people have the right to live in a healthy environment, to be protected against environmental hazards, and to participate in decisions affecting their communities. Communities of color and low-income populations live, work, and play in environments with disproportionate exposure to hazards associated with allergic disease. This unequal distribution of hazards has contributed to health disparities and is largely the result of systemic racism that promotes segregation of neighborhoods, disinvestment in predominantly racial/ethnic minority neighborhoods, and discriminatory housing, employment, and lending practices. The AAAAI Environmental Exposure and Respiratory Health Committee and Diversity, Equity and Inclusion Committee jointly developed this report to improve allergy/immunology specialists' awareness of environmental injustice, its roots in systemic racism, and its impact on health disparities in allergic disease. We present evidence supporting the relationship between exposure to environmental hazards, particularly at the neighborhood level, and the disproportionately high incidence and poor outcomes from allergic diseases in marginalized populations. Achieving environmental justice requires investment in at-risk communities to increase access to safe housing, clean air and water, employment opportunities, education, nutrition, and health care. Through policies that promote environmental justice, we can achieve greater health equity in allergic disease.

Assessment of adherence to corticosteroids in asthma by drug monitoring or fractional exhaled nitric oxide: A literature review

Background

Although the efficacy of corticosteroid treatment in controlling asthma is widely accepted, its effectiveness is undermined by poor adherence. However, the optimal method for measuring adherence to asthma therapy remains unclear.

Objective

To perform a review of the literature reporting biological, objective methods for assessing adherence to inhaled or oral corticosteroids in asthma; we included studies reporting direct measurement of exogenous corticosteroids in blood, or the effect of adherence on exhaled nitric oxide.

Design

We searched three databases MEDLINE (using both PubMed and Ovid), the Cumulative Index of Nursing and Allied Health Literature (CINAHL) and Web of Science for articles published between January 1975 and July 2020. Quality of the studies was assessed using the National Institute of Health checklist.

Results

From 2850 screened articles, 26 fulfilled the inclusion criteria. Measurement of blood prednisolone with or without cortisol was used in eight studies as a measure of oral corticosteroid adherence, and fractional exhaled nitric oxide (FeNO) in 17 studies for inhaled corticosteroid adherence. Inhaled corticosteroids were measured directly in the blood in one study. By direct measurement of drug levels in the blood, adherence rates to oral corticosteroids ranged from 47% to 92%, although the performance and timing of the test were often not known, making interpretation of findings and serum prednisolone concentrations difficult. FeNO is generally lower in adherent than non‐adherent patients, but no absolute cut‐off can be proposed based on the available data. However, a fall in FeNO following supervised inhaled corticosteroid dosing could indicate previous poor adherence.

Conclusions and Clinical Relevance

Despite prednisolone and cortisol levels commonly being used as adherence markers in clinical practice, further work is required to assess the influence of the dose and timing on blood levels. The promising findings of FeNO suppression testing should be explored in further prospective studies.

A randomized controlled trial of a community health worker delivered home-based asthma intervention to improve pediatric asthma outcomes

OBJECTIVE

The objective of this study was to evaluate the effects of using Community Health Workers (CHWs) to deliver the home-based Wee Wheezers asthma education program on asthma symptoms among children with persistent asthma.

METHODS

In this randomized controlled trial of 151 children aged 2-9 years with persistent asthma, we assigned 75 to the intervention and 76 to the control. The primary outcome was caregiver-reported asthma symptom days. Secondary outcomes included asthma-related healthcare utilization, caregivers' asthma knowledge, illness perception and management behaviors, MDI-spacer administration technique, and home environmental triggers. Outcomes were collected at baseline, 3, 6, 9 and 12 months. A repeated measurements analytic approach with generalized estimating equations was used. To account for missing data, multiple imputation methods were employed.

RESULTS

At 3 and 6 months, improvement in symptom days was not significantly different between groups. However, at 9 and 12 months, the reduction in asthma symptom days was 2.15 and 2.31 days more respectively for those in the intervention group compared to the control. Improvements in MDI-spacer technique, knowledge and attitudes were significant throughout follow-up. Improvement in habits regarding MDI use was significant at 3 and 6 months, and asthma routines were improved at 3 months. However, there was no change in asthma-related healthcare utilization or home environmental triggers.

CONCLUSION

Using CHWs to deliver a home-based asthma education program to caregivers of children with persistent asthma led to improvements in symptom days and several secondary outcomes. Expanding the use of CHWs to provide home-based interventions can help reduce disparities in children's health outcomes.

Health provider perspectives of electronic medication monitoring in outpatient asthma care: a qualitative investigation using the consolidated framework for implementation research

OBJECTIVE

Little is known about the implementation challenges health providers might face with the use of digital health in outpatient asthma care. To qualitatively explore the experience of health providers with electronic medication monitoring (EMM) using an implementation science framework.

METHODS

Using the Consolidated Framework of Implementation Research (CFIR), we conducted interviews (n = 10) exploring health providers' experience with EMM with asthma patients from 5 primary care or specialty clinics. The EMM tracked albuterol and inhaled corticosteroid (ICS) use, and health providers called parents whenever ICS adherence waned, or albuterol use increased. Interviews were audio-recorded, transcribed, and deductively analyzed using directed content analysis.

RESULTS

Health providers reported the intervention's primary advantage, compared with current asthma care, was the ability to monitor medication use at-home. Most felt the intervention improved care delivery. Nurses and medical assistants described a process of phone calls and checking alerts, that had varying levels of administrative burden and complexity. Health providers felt that sustained implementation of the intervention model would require additional employees to handle the administrative and clinical workload. Half of the interviewed providers were unsure if patient needs were met by the intervention, while some cited technology syncing issues, others liked the enhanced interactions for asthma education.

CONCLUSION

Health providers reported positive experiences supporting parents and children with asthma using EMM but also highlighted intervention components that needed improvement or refinement to yield successful implementation in outpatient pediatric clinics. Recommendations for enhancing the intervention for a scaled-up implementation were discussed.

Race and Asthma Outcomes in Older Adults: Results from the National Asthma Survey

BACKGROUND

The number of older adults with asthma continues to rise, yet the effects of race and ethnicity on asthma outcomes in this population are unknown.

OBJECTIVE

To characterize the effect of race and ethnicity on asthma outcomes in a large national sample of older adults and to identify factors that are associated with disparities found.

METHODS

Data from the 2015 Behavioral Risk Factor Surveillance Survey and Asthma Call-Back Survey were analyzed. Respondents were included if they had a current asthma diagnosis, were aged ≥55, and self-identified as non-Hispanic white, African American, or Hispanic. Demographic variables, health care access, comorbidities, and asthma history were correlated with asthma outcomes (health care utilization and asthma control). Asthma outcome variables were further analyzed using multivariable logistic regression.

RESULTS

A total of 4700 individuals were included. Compared with non-Hispanic white respondents, African American and Hispanic respondents had lower incomes, greater impaired access to health care due to cost, and increased reliance on rescue medications. After controlling for factors including income, education, comorbidities, and health insurance, African American and Hispanic respondents were twice as likely to visit the emergency room (ER) for asthma (P < .001 for both) and 40% less likely to report uncontrolled daytime symptoms (P = .002 and .008).

CONCLUSIONS

Racial differences in asthma outcomes persist despite controlling for multiple social determinants of health and access to health insurance through Medicare. Minority patients were more likely to visit the ER but less likely to report frequent daytime symptoms. These findings indicate that comprehensive strategies to address assessment, monitoring, and treatment are needed to decrease health disparities.

Concordance among children, caregivers, and clinicians on barriers to controller medication use

OBJECTIVE

While much research has addressed asthma medication adherence, few have combined quantitative and qualitative data, and none has addressed the triad of child, caregiver, and clinician simultaneously. This study assessed, with mixed methods, barriers to medication adherence within this triad.

METHODS

We conducted interviews with publicly-insured children with asthma, their caregivers, and their primary-care clinicians. Children (7-17 years) had been prescribed daily inhaled corticosteroids and visited the ED for asthma (past year). Participants answered open-ended and survey questions, rating suggested barriers to medication use (never vs. ever a barrier). McNemar's tests compared report of barriers by each group (children, caregivers, clinicians), and assessed concordance within triads.

RESULTS

Fifty child-caregiver dyads participated (34 clinicians). Children (40% female; median age 10 years) had mostly non-Hispanic black (90%) caregivers with less than or equal to high-school education (68%). For barriers, children and clinicians were more likely than caregivers to report medications running out. Clinicians were also more likely to cite controllers being a "pain to take" (vs. children) and forgetfulness (vs. caregivers) (all p < .05). There was a lack of within-triad concordance regarding barriers to adherence, especially regarding medication running out, worrying about taking a daily medication, and medication being a pain to take. Qualitative data revealed themes of competing priorities, home routines, and division of responsibility as prominent contributors to medication adherence.

CONCLUSIONS

There was significant disagreement among children, caregivers, and clinicians regarding barriers to daily use of asthma medications. To tailor asthma management conversations, clinicians should understand family-specific barriers and child-caregiver disagreements.

Association of an Asthma Improvement Collaborative With Health Care Utilization in Medicaid-Insured Pediatric Patients in an Urban Community

IMPORTANCE

Asthma is the most common chronic condition of childhood. Hospitalizations and emergency department (ED) visits for asthma are more frequently experienced by minority children and adolescents and those with low socioeconomic status.

OBJECTIVE

To reduce asthma-related hospitalizations and ED visits for Medicaid-insured pediatric patients residing in Hamilton County, Ohio.

DESIGN, SETTING, AND PARTICIPANTS

From January 1, 2010, through December 31, 2015, a multidisciplinary team used quality-improvement methods and the chronic care model to conduct interventions in inpatient, outpatient, and community settings in a large, urban academic pediatric hospital in Hamilton County, Ohio. Children and adolescents aged 2 to 17 years who resided in Hamilton County, had a diagnosis of asthma, and were Medicaid insured were studied.

INTERVENTIONS

Interventions were implemented in 3 phases: hospital-based inpatient care redesign, outpatient-based care enhancements, and community-based supports. Plan-do-study-act cycles allowed for small-scale implementation of change concepts and rapid evaluation of how such tests affected processes and outcomes of interest.

MAIN OUTCOMES AND MEASURES

The study measured asthma-related hospitalizations and ED visits per 10 000 Medicaid-insured pediatric patients. Data were measured monthly on a rolling 12-month mean basis. Data from multiple previous years were used to establish a baseline. Data were tracked with annotated control charts and with interrupted time-series analysis.

RESULTS

Of the estimated 36 000 children and adolescents with asthma in Hamilton County (approximately 13 000 of whom are Medicaid insured and 6000 of whom are cared for in Cincinnati Children's Hospital primary care practices), asthma-related hospitalizations decreased from 8.1 (95% CI, 7.7-8.5) to 4.7 (95% CI, 4.3-5.1) per 10 000 Medicaid patients per month by June 30, 2014, a 41.8% (95% CI, 41.7%-42.0%) relative reduction. Emergency department visits decreased from 21.5 (95% CI, 20.6-22.3) to 12.4 (95% CI, 11.5-13.2) per 10 000 Medicaid patients per month by June 30, 2014, a 42.4% (95% CI, 42.2%-42.6%) relative reduction. Improvements were sustained for the subsequent 12 months. The proportion of patients who were rehospitalized or had a return ED visit for asthma within 30 days of an index hospitalization was reduced from 12% to 7%. The proportion of patients with documented well-controlled asthma in this study's primary care population increased from 48% to 54%.

CONCLUSIONS AND RELEVANCE

An integrated, multilevel approach focused on enhancing availability and accessibility of treatments, removing barriers to adherence, mitigating multidomain risks, augmenting self-management, and creating a collaborative relationship between the family and the health care system was associated with improved asthma outcomes for a population of Medicaid-insured pediatric patients. Similar models used in accountable care organizations or across patient panels and with other chronic conditions could be feasible and warrant evaluation.

Enhancing Respiratory Medication Adherence: The Role of Health Care Professionals and Cost-Effectiveness Considerations

Adherence to medication comprises a multiphased temporal process involving (1) initiation of prescribed therapy, (2) implementation as prescribed, and (3) subsequent persistence. Medication adherence remains suboptimal in most patients with long-term respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). Interventions have been shown to effectively improve treatment initiation, implementation, and persistence when delivered at the health care professional level or the system level, but demonstration of the cost-effectiveness of these interventions is necessary to ensure their widespread use. This review summarizes how health care professionals can intervene to improve medication adherence in patients with asthma and COPD, provides some examples of effective primary care interventions, and illustrates some of the challenges to optimal implementation arising from cost-effectiveness modeling. Improving adherence is shown to be an economically viable treatment option for patients with asthma and COPD, but there are differences in the health economics pertaining to each condition and setting that can affect whether an intervention is considered cost-effective. Targeting adherence interventions at patients with the greatest to gain, and tailoring them to individual patient needs, may help to optimize cost-effectiveness ratios and improve the probability of positive reimbursement decisions, systemwide implementation, and resultant health benefits.

Interprofessional Pulmocheck care pathway: An innovative approach to managing pediatric asthma care in the Netherlands

OBJECTIVES

Under-diagnosis and suboptimal asthma control in children persists. An innovative care pathway was developed by a hospital department of pediatrics with the aim to detect pulmonary problems in children and provide appropriate treatment possibilities through systematic feedback towards the referring primary care physician. Primary care physicians can use this pathway to refer children with asthma-like symptoms for a one-day assessment. Goals are to measure the usage of the pathway by primary care general practitioners (GPs), the outcomes in terms of new diagnoses of asthma, the reduction in regular referrals, generated recommendations/therapy and the adequacy of asthma follow-up.

METHODS

We collected all feedback letters sent to the GP concerning children who underwent the Pulmocheck in 2010, 2011 and 2012. Furthermore, all GPs, who had referred a child to the Pulmocheck in this period and that subsequently was diagnosed with asthma and was further managed in primary care, were sent a follow-up questionnaire in 2014.

RESULTS

There were 121 referrals from 51 GPs in 3 years to this pathway. In 59.5% of these referrals a new diagnosis of asthma was established. In 90.9% one or more changes in clinical management were advised. The response rate to the follow-up questionnaires was 65.7% of which 4.8% of the children with new established asthma were reviewed four times or more in the follow-up period, 17.4% two times, 65.2% once, and in 8.7% were not followed.

CONCLUSIONS

The specialty pediatric asthma care pathway revealed a high number of children with newly diagnosed asthma, but was also helpful to exclude this diagnosis. However, the referral rate of GPs to this pathway was low, but in the children, that were referred several changes in the clinical management were advised and the frequency of monitoring of the children with diagnosed asthma was not in accordance with the asthma guidelines.

Parental Perceptions and Practices toward Childhood Asthma

Introduction. Parental perceptions and practices are important for improving the asthma outcomes in children; indeed, evidence shows that parents of asthmatic children harbor considerable misperceptions of the disease. Objective. To investigate the perceptions and practices of parents toward asthma and its management in Saudi children. Methods. Using a self-administered questionnaire, a two-stage cross-sectional survey of parents of children aged between 3 and 15 years, was conducted from schools located in Riyadh province in central Saudi Arabia. Results. During the study interval, 2000 parents were asked to participate in the study; 1450 parents responded, of whom 600 (41.4%) reported that their children had asthma, dyspnea, or chest allergy (recurrent wheezing or coughing), while 478 (32.9%) of the parents reported that their children were diagnosed earlier with asthma by a physician. Therefore, the final statistical analyses were performed with 600 participants. Furthermore, 321 (53.5%) respondents believed that asthma is solely a hereditary disease. Interestingly, 361 (60.3%) were concerned about side effects of inhaled corticosteroids and 192 (32%) about the development of dependency on asthma medications. Almost 76% of parents had previously visited a pediatric emergency department during an asthma attack. Conclusions. Parents had misperceptions regarding asthma and exhibited ineffective practices in its management. Therefore, improving asthma care and compliance requires added parental education.

Mismatching Among Guidelines, Providers, and Parents on Controller Medication Use in Children with Asthma

BACKGROUND

Underuse of controller medicines among children with asthma remains widespread despite national guidelines.

OBJECTIVES

To (1) assess provider prescribing patterns for asthma controller medications; (2) assess how frequently parents' reports of their child's asthma controller medicine use were mismatched with their provider's recommendations; and (3) evaluate parent attitudes and demographic characteristics associated with these mismatches.

METHODS

In this cross-sectional study, we conducted linked surveys of parents and providers of children with probable persistent asthma in a Medicaid program and 4 commercial health plans in 2011. Probable persistent asthma was defined as a diagnosis of asthma and 1 or more controller medication dispensing.

RESULTS

This study included 740 children (mean age, 8.6 years). Providers for 50% of the children reported prescribing controller medications for daily year-round use, 41% for daily use during active asthma months, and 9% for intermittent use for relief. Among parents, 72% knew which class of controller medication the provider prescribed and 49% knew the administration frequency and the medication class. Parents were less likely to report the same controller medication type as the provider, irrespective of dose and frequency, if they were Latino (odds ratio [OR], 0.23; CI, 0.057-0.90), had a household smoker (OR, 2.87; CI, 0.42-19.6), or believed the controller medicine was not helping (OR, 0.15; CI, 0.048-0.45).

CONCLUSIONS

Mismatches between parent reports and providers intentions regarding how the child was supposed to use inhaled steroids occurred for half of the children. Efforts should focus on ways to reduce mismatches between parent and provider intentions regarding controller medication use.

Effectiveness of a multi-level asthma intervention in increasing controller medication use: a randomized control trial

INTRODUCTION

Poor self-management by families is an important factor in explaining high rates of asthma morbidity in Puerto Rico, and for this reason we previously tested a family intervention called CALMA that was found effective in improving most asthma outcomes, but not effective in increasing the use of controller medications. CALMA-plus was developed to address this issue by adding to CALMA, components of provider training and screening for asthma in clinics.

METHODS

Study participants were selected from claims Medicaid data in San Juan, Puerto Rico. After screening, 404 children in eight clinics were selected after forming pairs of clinics and randomizing the clinics) to CALMA-only or CALMA-plus.

RESULTS

For all three primary outcomes at 12 months, the mean differences between treatment arms were small but in the predicted direction. However, after adjusting for clinic variation, the study failed to demonstrate that the CALMA-plus intervention was more efficacious than the CALMA-only intervention for increasing controller medication use, or decreasing asthma symptoms. Both groups had lower rates of asthma symptoms and service utilization, consistent with previous results of the CALMA-only intervention.

CONCLUSIONS

Compliance of providers with the intervention and training, small number of clinics available and the multiple barriers experienced by providers for medicating may have been related to the lack of difference observed between the groups. Future interventions should respond to the limitations of the present study design and provide more resources to providers that will increase provider participation in training and implementation of the intervention.

Non-adherence to inhaled corticosteroids and the risk of asthma exacerbations in children

BACKGROUND

Non-adherence to inhaled corticosteroids (ICSs) is a major risk factor for poor asthma control in children. However, little is known about the effect of adherence to ICS on the incidence of asthma exacerbations. The objective of this study was to examine the effect of poor adherence to ICS on the risk of exacerbations in children with asthma.

METHODS

In this nested case-control study using data from the Dutch PHARMO Record Linkage System, children aged 5-12 years who had an asthma exacerbation needing oral corticosteroids or hospital admission were matched to patients without exacerbations. Refill adherence was calculated as medication possession ratio from ICS-dispensing records. Data were analyzed using a multivariable multiplicative intensity regression model.

RESULTS

A total of 646 children were included, of whom 36 had one or more asthma exacerbations. The medication possession ratio was 67.9% (standard deviation [SD] 30.2%) in children with an exacerbation versus 54.2% (SD 35.6%) in the control group. In children using long-acting beta-agonist, good adherence to ICS was associated with a higher risk of asthma exacerbations: relative risk 4.34 (95% confidence interval: 1.20-15.64).

CONCLUSION

In children with persistent asthma needing long-acting beta-agonist, good adherence to ICS was associated with an increased risk of asthma exacerbations. Possible explanations include better motivation for adherence to ICS in children with more severe asthma, and reduced susceptibility to the consequences of non-adherence to ICS due to overprescription of ICS to children who are in clinical remission. Further study into the background of the complex interaction between asthma and medication adherence is needed.

The Impact of Internet Health Information on Patient Compliance: A Research Model and an Empirical Study

Background

Patients have been increasingly seeking and using Internet health information to become more active in managing their own health in a partnership with their physicians. This trend has both positive and negative effects on the interactions between patients and their physicians. Therefore, it is important to understand the impact that the increasing use of Internet health information has on the patient-physician relationship and patients’ compliance with their treatment regimens.

Objective

This study examines the impact of patients’ use of Internet health information on various elements that characterize the interactions between a patient and her/his physician through a theoretical model based on principal-agent theory and the information asymmetry perspective.

Methods

A survey-based study consisting of 225 participants was used to validate a model through various statistical techniques. A full assessment of the measurement model and structural model was completed in addition to relevant post hoc analyses.

Results

This research revealed that both patient-physician concordance and perceived information asymmetry have significant effects on patient compliance, with patient-physician concordance exhibiting a considerably stronger relationship. Additionally, both physician quality and Internet health information quality have significant effects on patient-physician concordance, with physician quality exhibiting a much stronger relationship. Finally, only physician quality was found to have a significant impact on perceived information asymmetry, whereas Internet health information quality had no impact on perceived information asymmetry.

Conclusions

Overall, this study found that physicians can relax regarding their fears concerning patient use of Internet health information because physician quality has the greatest impact on patients and their physician coming to an agreement on their medical situation and recommended treatment regimen as well as patient’s compliance with their physician’s advice when compared to the impact that Internet health information quality has on these same variables. The findings also indicate that agreement between the patient and physician on the medical situation and treatment is much more important to compliance than the perceived information gap between the patient and physician (ie, the physician having a higher level of information in comparison to the patient). In addition, the level of agreement between a patient and their physician regarding the medical situation is more reliant on the perceived quality of their physician than on the perceived quality of Internet health information used. This research found that only the perceived quality of the physician has a significant relationship with the perceived information gap between the patient and their physician and the quality of the Internet health information has no relationship with this perceived information gap.

Caregiver quality of life in pediatric asthma: associations with beliefs and concerns about medications and emergency department use

OBJECTIVE

To examine caregiver quality of life (QOL) related to pediatric asthma among families from Latino, African American, and non-Latino white (NLW) backgrounds.

METHODS

In all, 94 children with persistent asthma (6-15 years) and their primary caregivers completed interview-administered questionnaires.

RESULTS

Overall QOL and subscale scores differed across race/ethnicity, with NLW caregivers reporting higher QOL. Caregivers who expressed more concerns about their child's medications and more beliefs in the necessity of asthma medications had lower QOL. In African American and Latino families, caregiver QOL mediated the association between beliefs about the necessity of asthma medications and child emergency department (ED) use.

CONCLUSIONS

Caregiver beliefs and concerns related to child asthma medications may begin to explain differences in caregiver QOL across NLW, Latino, and African American caregivers. Caregiver QOL may be a mechanism by which caregiver beliefs and concerns about asthma medications are associated with child ED use.

Geographic and racial variation in asthma prevalence and emergency department use among Medicaid-enrolled children in 14 southern states

BACKGROUND

Despite evidence-based prevention and practice guidelines, asthma prevalence, treatment, and outcomes vary widely at individual and community levels. Asthma disproportionate/ly affects low-income and minority children, who comprise a large segment of the Medicaid population.

METHODS

2007 Medicaid claims data from 14 southern states was mapped for 556 counties to describe the local area variation in 1-year asthma prevalence rates, emergency department (ED) visit rates, and racial disparity rate ratios.

RESULTS

One-year period prevalence of asthma ranged from 2.8% in Florida to 6.4% in Alabama, with a median prevalence rate of 4.1%. At the county level, the prevalence was higher for Black children and ranged from 1.03% in Manatee County, FL, to 21.0% in Hockley County, TX. Black-White rate ratios of prevalence ranged from 0.49 in LeFlore County, MS, to 3.87 in Flagler County, FL. Adjusted asthma ED visit rates ranged from 2.2 per 1000 children in Maryland to 16.5 in Alabama, with a median Black-White ED-visit rate ratio of 2.4. Rates were higher for Black children, ranging from 0.80 per 1000 in Wicomico County, MD, to 70 per 1000 in DeSoto County, FL. Rate ratios of ED visits ranged from 0.25 in Vernon Parish, LA, to 25.28 in Nelson County, KY.

CONCLUSIONS AND RELEVANCE

Low-income children with Medicaid coverage still experience substantial variation in asthma prevalence and outcomes from one community to another. The pattern of worse outcomes for Black children also varies widely across counties. Eliminating this variation could substantially improve overall outcomes and eliminate asthma disparities.

Mismatch between asthma symptoms and spirometry: implications for managing asthma in children

OBJECTIVES

To examine the concordance between spirometry and asthma symptoms in assessing asthma severity and beginning therapy by the general pediatrician.

STUDY DESIGN

Between 2008 and 2012, spirometry testing was satisfactorily performed in 894 children (ages 5-19 years) whose asthma severity had been determined by their pediatrician using asthma guideline-based clinical criteria. Spirometry-determined asthma severity using national asthma guidelines and clinician-determined asthma severity were compared for concordance using weighted Kappa coefficients.

RESULTS

Thirty percent of participants had clinically determined intermittent asthma; 32%, 33%, and 5% had mild, moderate, and severe, persistent asthma, respectively. Increasing disease severity was associated with decreases in the forced expiratory volume in 1 second/forced vital capacity (FVC) ratio (P < .001), the forced expiratory volume in 1 second/FVC% predicted (P < .0001), and the FVC% predicted (P < .01). In 319 children (36%), clinically determined asthma severity was lower than spirometry-determined severity. Concordance was 0.16 (95% CI 0.10, 0.23), and when adjusted for bias and prevalence, was 0.20 (95% CI 0.17, 0.23). When accounting for age, sex, exposure to smoke, and insurance type, only spirometry-determined asthma severity was a significant predictor of agreement (P < .0001), with worse agreement as spirometry-determined severity increased.

CONCLUSIONS

Concordance between spirometry and asthma symptoms in determining asthma severity is low even when guideline-based clinical assessment tools are used. Because appropriate therapy reduces asthma morbidity and is guided by disease severity, results from spirometry testing could better guide pediatricians in determining appropriate therapy for their patients with asthma.

Medication adherence and the risk of severe asthma exacerbations: a systematic review

The benefits of drug therapy for asthma have been well established, but adherence to treatment is poor, and this might be associated with an increased risk of asthma exacerbations. The aim of this study was to review the literature on the association between adherence to asthma controller treatment and risk of severe asthma exacerbations in children and adults.

A systematic literature search was performed in PubMed, Embase and Web of Science, from inception until January 2014. Studies were included if data on the association between medication adherence and severe asthma exacerbations were presented. Quality was assessed using a modified version of the Newcastle–Ottawa Scale.

The search yielded 2319 unique publications, of which 23 met the inclusion criteria and underwent data extraction and quality scoring. High levels of heterogeneity across studies with regard to adherence and exacerbation measurements, designs and analysis precluded a formal meta-analysis. Although effect measures varied widely, good adherence was associated with fewer severe asthma exacerbations in high-quality studies.

Good adherence tended to be associated with lower risk of severe asthma exacerbations. Future studies should use standardised methodology to assess adherence and exacerbations, and should consider inhaler competence.

Shared clinician-patient decision-making about treatment of pediatric asthma: what do we know and how can we use it?

PURPOSE OF REVIEW

Shared decision-making (SDM) is an emerging field that promises to improve healthcare. We aim to explore the concept of SDM, how it has been studied or applied in the treatment of asthma, and how it might be implemented to improve adherence and outcomes in pediatric asthma.

RECENT FINDINGS

Healthcare providers often fail to involve their patients in clinical decision-making by not presenting all available options, associated risks and benefits, in light of the patient's values, preferences, concerns, lifestyle, and perceived barriers to following various treatment regimens. It has been argued that SDM is preferable to a clinician-controlled approach and may improve patient outcomes (increase satisfaction with care, reduce decisional conflict and decisional regret, improve health-related quality of life, and increase decision-specific knowledge). This may be especially important in managing chronic conditions in which adherence to treatment regimen may increase if the patient was actively involved in the decision-making. In pediatrics, the decision process is further complicated by the clinician-parent(s)-child interaction. We found no studies on how to effectively involve and communicate with children at different developmental levels, or how to coalesce the parent and child's perspective to work as a unit.

SUMMARY

SDM has the promise to improve satisfaction with disease management, treatment adherence and patient-centered outcomes in pediatric asthma, but further research is needed to determine its effectiveness and to establish guidelines on how to implement SDM in the clinical setting and incorporate the input and preferences of all stakeholders' perspectives.

Role of health education and self-action plan in improving the drug compliance in bronchial asthma

BACKGROUND

Considering the prevalence and associated burden of disease due to bronchial asthma, it is mandatory to obtain an optimal control of the disease and to improve outcomes for these patients. But it has been observed that there is very poor adherence to the inhalational therapy which leads to the suboptimal control of the disease.

OBJECTIVES OF THE STUDY

To study the adherence for aerosol therapy in bronchial asthma patients and to assess the impact of health education and self-action plan in improving the compliance to the therapy.

METHODOLOGY

A prospective study was done in a total of 500 bronchial asthma patients over a period of 2 years. Once included in the study, the patients were followed-up for a total of 12 weeks for calculation of nonadherence to the aerosol therapy. In nonadherent patients, we employed various health education strategies to improve the compliance in these cases.

RESULTS

A total of 500 patients of bronchial asthma who were started on aerosol therapy over duration of 2 years were included in the study. At the end of 12 weeks, it was observed that, only 193 patients (38.6%) had regular compliance and 307 patients (61.4%) were noncompliant to aerosol therapy as prescribed for bronchial asthma. Factors that were associated with poor compliance were: Lower educational level status, poor socioeconomic status, cumbersome regimens, dislike of medication, and distant pharmacies. Nondrug factors that reduced the compliance were: Fears about side effects, anger about condition or its treatment, forgetfulness or complacency, and patient's ill attitudes toward health. After employing the various strategies for improving the compliance in these patients, the compliance increased in 176 patients (57.3%) among the earlier defaulted patients, while the remaining 131 patients (42.7%) were found to be noncompliant even after various educational techniques.

CONCLUSION

Noncompliance in asthma management is a fact of life and no single compliance improving strategy probably will be as effective as a good physician-patient relationship. Optimal self-management allowing for optimization of asthma control by adjustment of medications may be conducted by either self-adjustment with the aid of a written action plan or by regular medical review. Individualized written action plans based on peak expiratory flow are equivalent to action plans based on symptoms.

Using communication skills to improve adherence in children with chronic disease: the adherence equation

Nonadherence to maintenance medication is common in paediatric chronic conditions. Despite the common belief that nonadherence is therapy-resistant, and the apparent lack of evidence for successful interventions to improve adherence, there is, in fact, a considerable body of evidence suggesting that adherence can be improved by applying specific communicative consultation skills. These can be summarized as the adherence equation: adherence=follow-up+dialogue+barriers and beliefs+empathy and education => concordance. Close follow-up of children with a chronic condition is needed to establish a therapeutic partnership with the family. Teaching self management skills is not a unidirectional process of providing information, but requires a constructive and collaborative dialogue between the medical team and the family. Identifying barriers to adherence can be achieved in a non-confrontational manner, by showing a genuine interest what the patient's views and preferences are. In particular, parental illness perceptions and medication beliefs should be identified, because they are strong drivers of nonadherence. Through empathic evidence-based education, such perceptions and beliefs can be modified. By applying these strategies, concordance between the child's family and the medical team can be achieved, resulting in optimal adherence to the jointly created treatment plan.

Every parent tells a story: why non-adherence may persist in children receiving guideline-based comprehensive asthma care

OBJECTIVE

Effective self-management and adherence to inhaled corticosteroids are issues of particular interest in comprehensive asthma care. In spite of this care, however, a number of parents and children remain non-adherent. The reasons for this non-adherence have up till now been unknown, because previous adherence studies have based their findings either on populations with poor adherence or on unreliable self-reported adherence. This study was designed to explore factors that contribute to persistent non-adherence to inhaled corticosteroids in children ranging between 2 and 12 years of age receiving comprehensive asthma care, with adherence assessed objectively.

METHODS

This qualitative study was based on in-depth interviews which took place in the homes of parents whose children had completed a one-year follow-up of electronically measured adherence to inhaled corticosteroids. Rich and comprehensive descriptions of parents' own accounts of self-management behavior were obtained using active listening techniques. Each interview was recorded and transcribed verbatim followed by data analysis using standard methodology for qualitative studies.

RESULTS

Twenty children's parents (mean age 5.9 years) were interviewed. Distinctive patterns of modifiable barriers to adherence emerged, including a novel finding of parents misjudging their child's ability to manage the daily use of medication by him/herself. Persistent non-adherence appeared to be caused by a number of maintaining factors. Most noticeable factors were unawareness of non-adherence by both parents and health care providers, a lack of parental drive to achieve high adherence and ineffective parental problem-solving behaviour.

CONCLUSIONS

This study has identified modifiable barriers to adherence in families participating in a comprehensive asthma care programme. Future studies are needed to verify our novel findings and to investigate whether interventions around these barriers are needed to increase the effectiveness of asthma care programs.

Prescription fill patterns in underserved children with asthma receiving subspecialty care

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 β-agonists (SABAs) with no refills. Only 49.1% of inhaled corticosteroid (ICS), 49.5% of combination ICS and long-acting β-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.

Disparities in Asthma Care, Management, and Education Among Children With Asthma

Health disparities are pervasive in the United States. Health and health care disparities are the differences or gaps in health (eg, life expectancy, morbidity, risk factors, and quality of life) and health care access and quality between segments of the United States population as related to race/ethnicity and socioeconomic status (eg, income, education). Multiple factors are associated with such disparities in asthma management and education. This article explores some of those factors and summarizes the strategies developed and interventions implemented to address disparities associated with asthma care and education among racial and ethnic minority children. It also discusses the need for further research to identify effective asthma education approaches for improving the management of asthma among racial and ethnic minority children. More exploration of the root causes of health care disparities, including policy studies in the area of social determinates of health and health equity, is also needed.

Dosing variability in prescriptions of acetaminophen to children: comparisons between pediatricians, family physicians and otolaryngologists

BACKGROUND

To estimate the extents of dosing variability in prescriptions of acetaminophen to children among pediatricians, family physicians and otolaryngologists.

METHODS

The acetaminophen prescriptions in the systematic sampling datasets from the National Health Insurance Research Database in Taiwan were analyzed. The distribution of dosages was measured and expressed in terms of coefficient of variation (CV). The analyses were stratified by patient's age, prescriber's specialty and preparation form.

RESULTS

From 13,868 prescribed items of acetaminophen in 2009, liquids accounted only for 11.1% (n = 1544). More than half (56.9%) of liquids were prescribed by pediatricians. The median dose (83.3 mg, n = 1683) of acetaminophen prescriptions in infants is around half of that in preschool children (166.7 mg, n = 3921), one-third in children (250.0 mg, n = 4926) and one-sixth in adolescents (500.0 mg, n = 3338). In infants, the prescriptions by pediatricians had the highest CV (86.7%), followed by family physicians (82.3%) and otolaryngologists (70.3%). The patterns were similar in preschool children and children, but the difference of CV among specialties narrowed down with the patient's age.

CONCLUSIONS

In acetaminophen prescriptions to children, pediatricians had a wider variability of dosages and a higher ratio of liquid preparations than family physicians and otolaryngologists. Further investigations can be undertaken to estimate the accuracy of dosing variability as an indicator of prescribing quality. Besides, child-suitable drug preparations should be promoted to ensure patient safety.

Managing asthma in Black children

Black children bear a disproportionate burden of asthma when compared to other segments of the population. This study assessed the role of symptom scores, spirometry testing, and serum-specific immunoglobulin E in the primary care management of asthma in Black children.

Caregiver expectations of clinicians during the asthma diagnostic process in young children: thematic analysis of focus groups

OBJECTIVE

Asthma is difficult to diagnose in young children, and the subjective experience of caregivers varies. Clinicians' ability to meet caregiver expectations during the diagnostic process improves the caregiver-clinician relationship, and effectiveness of disease management strategies.

METHODS

We performed thematic analysis of seven focus groups (FGs) with 38 caregivers of children 1-6 years old diagnosed with asthma in the preceding 12 months. Caregivers were classified as satisfied or dissatisfied with clinicians during the asthma diagnostic process. Differential themes in these two groups identified caregiver expectations that determined satisfaction with the diagnostic process.

RESULTS

Caregiver expectations during the asthma diagnostic process included (1) provision of a diagnostic strategy, (2) acknowledgment of caregiver advocacy, (3) addressing caregiver's beliefs about treatment with asthma medications before a diagnosis was confirmed, and (4) discussing asthma specialist involvement in the diagnosis. Higher perceived severity of a child's illness made caregiver expectations more difficult to meet.

CONCLUSIONS

We conclude that clinicians considering an asthma diagnosis in young children must include a diagnostic strategy that is congruent with the caregiver's beliefs about the underlying illness, use of medication, and asthma specialist involvement. Perceived illness severity must also be accounted for when designing a diagnostic strategy.

Adequate levels of adherence with controller medication is associated with increased use of rescue medication in asthmatic children

Background

The role of asthma controller medication adherence and the level of asthma control in children is poorly defined.

Aims

To assess the association between asthma controller medication adherence and asthma control in children using routinely acquired prescribing data.

Methods

A retrospective observational study of children aged 0–18 years prescribed inhaled corticosteroids only (ICS), leukotriene receptors antagonists (LTRA), or long-acting β2 agonists (LABA) and ICS prescribed as separate or combined inhalers, between 01/09/2001 and 31/08/2006, registered with primary care practices contributing to the Practice Team Information database. The medication possession ratio (MPR) was calculated and associations with asthma control explored. Poor asthma control was defined as the issue of prescriptions for ≥1 course of oral corticosteroids (OCS) and/or ≥6 short-acting β2 agonists (SABA) canisters annually.

Results

A total of 3172 children prescribed asthma controller medication were identified. Of these, 15–39% (depending on controller medication) demonstrated adequate MPR. Adequate MPR was associated with male gender, good socio-economic status, and oral LTRA therapy. Adequate MPR was more likely to be associated with increased use of rescue medication. However logistic regression only identified a significant relationship for ICS only (odds ratio [OR], 1.89; 95% confidence interval [CI], 1.35–2.48; p<0.001), LTRA (OR, 2.11; 95% CI, 1.27–3.48; p = 0.004) and LABA/ICS (OR, 2.85; 95% CI, 1.62–5.02; p<0.001).

Conclusion

Poor adherence was observed for all asthma controller medications, although was significantly better for oral LRTA. In this study adequate adherence was not associated with the use of less rescue medication, suggesting that adherence is a complex issue.

Partner randomized controlled trial: study protocol and coaching intervention

BACKGROUND

Many children with asthma live with frequent symptoms and activity limitations, and visits for urgent care are common. Many pediatricians do not regularly meet with families to monitor asthma control, identify concerns or problems with management, or provide self-management education. Effective interventions to improve asthma care such as small group training and care redesign have been difficult to disseminate into office practice.

METHODS AND DESIGN

This paper describes the protocol for a randomized controlled trial (RCT) to evaluate a 12-month telephone-coaching program designed to support primary care management of children with persistent asthma and subsequently to improve asthma control and disease-related quality of life and reduce urgent care events for asthma care. Randomization occurred at the practice level with eligible families within a practice having access to the coaching program or to usual care. The coaching intervention was based on the transtheoretical model of behavior change. Targeted behaviors included 1) effective use of controller medications, 2) effective use of rescue medications and 3) monitoring to ensure optimal control. Trained lay coaches provided parents with education and support for asthma care, tailoring the information provided and frequency of contact to the parent's readiness to change their child's day-to-day asthma management. Coaching calls varied in frequency from weekly to monthly. For each participating family, follow-up measurements were obtained at 12- and 24-months after enrollment in the study during a telephone interview. The primary outcomes were the mean change in 1) the child's asthma control score, 2) the parent's quality of life score, and 3) the number of urgent care events assessed at 12 and 24 months. Secondary outcomes reflected adherence to guideline recommendations by the primary care pediatricians and included the proportion of children prescribed controller medications, having maintenance care visits at least twice a year, and an asthma action plan. Cost-effectiveness of the intervention was also measured.

DISCUSSION

Twenty-two practices (66 physicians) were randomized (11 per treatment group), and 950 families with a child 3-12 years old with persistent asthma were enrolled. A description of the coaching intervention is presented.

Respiratory medication adherence in chronic lung disease of prematurity

BACKGROUND

Chronic lung disease of prematurity (CLDP) is a frequent complication of premature birth. Infants and children with CLDP are often prescribed complex medication regimens, which can be difficult for families to manage.

OBJECTIVE

We sought to determine whether non-adherence was associated with increased CLDP-related morbidities and to identify predictors of adherence.

METHODS

Recruited caregivers of 194 children with CLDP completed questionnaires regarding self-reported adherence, respiratory outcomes, and quality of life (January 2008-June 2010). Adherence data were available for 176 subjects, of whom 143 had self-reported data only, and 33 had prescription claims data, which were used to calculate a medication possession ratio (MPR). Participants in the Prescription Claims Sample (n = 33) were more likely to have public insurance (P < 0.001).

RESULTS

Self-reported adherence substantially overestimated medication possession; the mean MPR was 38.8% (n = 33) and was not associated with self-reported adherence (P = 0.71; n = 26). In a small sample, higher MPR was associated with decreased odds ratios of visiting the emergency department (ED) (OR = 0.75 for a 10% increase in MPR [95%CI: 0.58, 0.97]; P = 0.03; n = 74 questionnaires from 28 participants), activity limitations (OR = 0.71 [95%CI: 0.53, 0.95]; P = 0.02; n = 70 questionnaires from 28 participants), and rescue medication use (OR = 0.84 [95%CI: 0.73-0.98]; P = 0.03; n = 70 questionnaires from 28 participants). Increasing caregiver worries regarding medication efficacy and side effects were associated with lower MPR (P = 0.04 and 0.02, respectively; n = 62 questionnaires from 27 participants). Socio-demographic and clinical risk factors were not predictors of MPR (n = 33).

CONCLUSIONS

We found that non-adherence with respiratory medications was common in premature infants and children with CLDP. Using multiple timepoints in a small sample, non-adherence was associated with a higher likelihood of respiratory morbidities. Although self-reported adherence and demographic characteristics did not predict MPR, concerns about medications did. We suggest that addressing caregiver concerns about medications may improve adherence and ultimately decrease CLDP-related morbidities. Larger, prospective studies are needed to confirm these findings and determine which factors predict non-adherence.

Parental perceptions and beliefs about childhood asthma: a cross-sectional study

Aim

To assess parental perceptions and beliefs about asthma in children.

Methods

We invited 6000 children aged 3 to 15 years from different schools in Lebanon to participate in the study from September 2007 to May 2008. In the first phase, in order to determine the prevalence of asthma in children, parents of all participating children filled out a small questionnaire. In the second phase, only parents of children with asthma filled out a detailed questionnaire about their perceptions of asthma.

Results

Phase I included parents of 4051 children, 574 (14%) of whom had asthma and were recruited to phase II. Out of these, 389 parents entered the final data analysis. Around 54% of parents believed that asthma was hereditary and 7% believed it was contagious. When asked about triggering factors, 51% stated virus infection, 75% dust, and 17% food. Sixty percent of children with asthma lived with someone who smoked. Sixty-seven percent of parents believed that herbs had a role in asthma treatment and only 49% received asthma education. There was a significant difference in education level (P = 0.01) between the parents who denied the label of asthma (79%) and those who accepted it (21%). Sixty-seven percent of parents preferred oral over inhaler treatment, 48% believed inhalers were addictive, 56% worried about inhalers’ side effects, and 76% worried about using inhaled corticosteroids. Significantly more parents from rural (53%) than from urban areas (38%) believed that inhalers were addictive (P = 0.004).

Conclusion

Parents of children with asthma had considerable misperceptions about the use of inhalers and the safety of inhaled corticosteroids. To improve asthma care in children, it is necessary to provide adequate education to parents.

Validation of a school-based written questionnaire for asthma case identification in Argentina

Recognition of asthma in community-based surveys can be problematic. We sought to develop and validate questionnaires that could identify elementary school-aged children likely to have asthma or who had poorly-controlled asthma. Questionnaires for parents (PQ) and students (SQ) to complete were developed using guidance on question wording from a focus group consisting of children with asthma and their parents. The gold standard for this study was a pulmonologist determination of asthma and this was used to calculate sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for each question and for combinations of questions. Questionnaires were distributed to 830 children attending elementary schools in Trelew, Argentina and 96% were returned. Test-retest reliability was determined in 221 randomly selected parents and children and very good levels of agreement were seen for individual questions. Asthma was diagnosed in 92 students. Overall, the PQ was able to detect asthma better than the SQ. Optimal diagnostic ability came by combining questions from the PQ and SQ. Not surprisingly, these questionnaires had a better NPV than PPV and can be used to determine which children require further evaluation.

Asthma in Head Start children: effects of the Breathmobile program and family communication on asthma outcomes

BACKGROUND

Asthma morbidity and mortality rates are high among young inner-city children. Lack of routine primary care provider visits, poor access to care, and poor patient-physician communication might be contributing factors.

OBJECTIVE

This study evaluated the effects of providing Breathmobile services only, a Facilitated Asthma Communication Intervention (FACI) only, or both Breathmobile plus FACI on asthma outcomes relative to standard care.

METHODS

Children with asthma (n = 322; mean age, 4 years; 53% male; 97% African American) were recruited from Head Start programs in Baltimore City and randomized into 4 groups. Outcome measures included symptom-free days (SFDs), urgent care use (emergency department visits and hospitalizations), and medication use (courses of oral steroids and proportion taking an asthma controller medication), as reported by caregivers at baseline, 6-month, and 12-month assessments. Generalized estimating equations models were conducted to examine the differential treatment effects of the Breathmobile and FACI compared with standard care.

RESULTS

Children in the combined treatment group (Breathmobile plus FACI) had an increase of 1.7 (6.6%) SFDs that was not maintained at 12 months. In intent-to-treat analyses the FACI-only group had an increase in the number of emergency department visits at 6 months, which was not present at 12 months or in the post hoc as-treated analyses. No significant differences were found between the intervention groups compared with those receiving standard care on all other outcome measures.

CONCLUSIONS

Other than a slight improvement in SFDs at 6 months in the Breathmobile plus FACI group, the intervention components did not result in any significant improvements in asthma management or asthma morbidity.

Medication use in children with asthma: not a child size problem

OBJECTIVE

The global burden of pediatric asthma is high. Governments and health-care systems are affected by the increasing costs of childhood asthma--in terms of direct health-care costs and indirect costs due to loss of parental productivity, missed school days, and hospitalizations. Despite the availability of effective treatment, the current use of medications in children with asthma is suboptimal. The purpose of this review is to scope the empirical literature to identify the problems associated with the use of pediatric asthma medications. The findings will help to design interventions aiming to improve the use of asthma medications among children.

METHODS

A literature search using electronic search engines (i.e., Medline, International Pharmaceutical Abstracts (IPA), PubMed, PsycINFO, and Cumulative Index to Nursing and Allied Health Literature (CINAHL)) and the search terms "asthma," "children," and "medicines" (and derivatives of these keywords) was conducted.

RESULTS

The search terms were expanded to include emergent themes arising out of search findings. Content themes relating to parents, children themselves, health-care professionals, organizational systems, and specific medications and devices were found. Within these themes, key issues included a lack of parental knowledge about asthma and asthma medications, lack of information provided to parents, parental beliefs and fears, parental behavioral problems, the high costs of medications and devices, the child's self-image, the need for more child responsibility, physician nonadherence to prescribing guidelines, "off-label" prescribing, poor understanding of teachers, lack of access to educational resources, and specific medications.

CONCLUSION

These key issues should be taken into account when modifying the development of educational tools. These tools should focus on targeting the children themselves, the parent/carers, the health-care professionals, and various organizational systems.

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.

Adherence with preventive medication in childhood asthma

Suboptimal adherence with preventive medication is common and often unrecognised as a cause of poor asthma control. A number of risk factors for nonadherence have emerged from well-conducted studies. Unfortunately, patient report a physician's estimation of adherence and knowledge of these risk factors may not assist in determining whether non-adherence is a significant factor. Electronic monitoring devices are likely to be more frequently used to remind patients to take medication, as a strategy to motivate patients to maintain adherence, and a tool to evaluate adherence in subjects with poor disease control. The aim of this paper is to review non-adherence with preventive medication in childhood asthma, its impact on asthma control, methods of evaluating non-adherence, risk factors for suboptimal adherence, and strategies to enhance adherence.

The Role of Parents' Medication Beliefs, Religious Problem-Solving, and Risks for Treatment Nonadherence in Urban Families with Asthma

Childhood asthma is highly prevalent, affecting approximately nine million children in the United States. Negative effects of pediatric asthma are disproportionately experienced by ethnic minorities living in low-income, urban settings. Given the great diversity in families' ways of addressing children's asthma symptoms, sociocultural factors underlying asthma disparities must be examined. The current study investigated associations among parents' beliefs about conventional and holistic/alternative medications, parents' religious problem-solving strategies and childrens' risks for asthma treatment nonadherence. The sample included 66 parents of ethnically diverse children with asthma living in urban settings. Factor analysis of the Religious Problem Solving Questionnaire yielded two factors, self-directed (ie, solving problems independently of God) and God-involved problem solving. Parents' strong positive beliefs about conventional and alternative medications were associated with greater self-directed problem solving and with more risks for nonadherence. Higher levels of self-directed problem solving also were associated with more risks for nonadherence. Self-directed problem solving mediated the associations of conventional and alternative medication beliefs with risks for nonadherence. Possible explanations for these findings are discussed.

Disparities in asthma medication dispensing patterns: the case of pediatric asthma in Puerto Rico

BACKGROUND

Disparities exist in asthma medication dispensing between children with public insurance and those with private insurance under a Managed Care Medicaid system in Puerto Rico.

OBJECTIVES

Island-wide medical claims data were used to examine the extent to which differences between the private and public health care sectors affect medication dispensing and health care utilization among asthmatic children.

METHODS

Children 3-18 years old with at least one service claim [outpatient, hospitalization, or emergency department (ED) visit] for asthma or reactive airway disease from 2005 to 2006 were selected. Chi-square analyses compared medication dispensing and health care utilization between the public and private sectors. Negative binomial regression identified factors associated with the mean dispensing rate of prescriptions for anti-inflammatory controller medication (CM).

RESULTS

Private insurance families (n = 28,088) were dispensed significantly more CM (48.3% vs. 12.0%) and quick relief medication (47.4% vs. 44.6%) than public insurance families (n = 13,220). The dispensing of inhaled corticosteroids (24.4% vs. 6.7%) and leukotriene modifiers and cromolyn (31.4% vs. 5.7%) was dramatically higher in the private sector. In contrast, emergency room use was significantly higher among public insurance children (51.7% vs. 13.8%). Multivariate analysis showed that age, number of β-agonists, and type of insurance was associated with CM dispensing; private insurance showed the greatest effect.

CONCLUSION

Asthmatic Puerto Rican children enrolled in public insurance were significantly less likely to be dispensed CM than children with private insurance; suggesting that under-treatment of public insured children may substantially contribute to increased asthma morbidity in this population as evidenced by significantly higher rates of ED visits.

CAPSULE SUMMARY

A disparity exists in asthma medication dispensing between children with public insurance compared with those with private insurance under a Managed Care Medicaid system in Puerto Rico. If asthma disparities in medication dispensing are to be reduced, then a better understanding of the complex ways in which multiple variables related to the health care system policies, socioeconomic factors, family and provider interactions, as well as the relative weight that each one contributes to the observed inequalities is needed.

Improving Communication Between Patients and Providers Using Health Information Technology and Other Quality Improvement Strategies: Focus on Low-Income Children

Effective communication between providers and patients has been linked to improved outcomes. Previous reviews of quality improvement strategies, including health information technology (health IT), have not focused on the needs of low-income children. The authors conducted a systematic review of the literature on studies of communication surrounding the care of low-income children, with an emphasis on interventions and health IT.The search yielded six studies that focused on low-income children; three of the studies used health IT. Key informant interviews provided insight to the current use of health IT for provider—patient communication in geographically diverse, underresourced settings.The authors identify gaps between existing literature and clinical practice. Future research should focus on the specific impact of health IT in pediatric medicine, particularly in underresourced and safety net settings. These efforts should focus on the use of technological innovations to improve care for low-income children and their families.

Perspectives on complementary and alternative therapies in asthma

Asthma is a chronic disease that affects millions of individuals living in the USA. Proper asthma management is essential for controlling asthma symptoms and exacerbations. In recent years, however, there has been increased recognition of individuals using complementary and alternative medicine (CAM) to treat asthma. This article reviews the status of the current literature on various cultural factors that influence CAM use. In addition, current research of two widely used forms of CAM, herbal remedies and relaxation techniques, is presented. Future directions and recommendations to increase the methodological rigor of CAM research are discussed, particularly as they pertain to herbal remedies and relaxation strategies. The importance of well-designed research studies, including observational studies and randomized controlled trials, is highlighted.

[Asthma treatment adherence]

Asthma is a very prevalent chronic disease in the general population, characterized by reversible obstruction of respiratory airways. Multiple studies demonstrate an improper control of the disease, and one of the main reasons for that is reduced adherence to treatment. Non -adherence can be classified as nonintentional or intentional, and the causes can be related to the motivations, beliefs and knowledge of the patient or due to the therapeutic regimen. The reasons for non -adherence are non -comprehension of the treatment goals; non -comprehension of disease severity; fears related to drugs; psychological conditions such as depression; complexity of treatment regimen; difficulties with administration route, mainly inhaler. After recognizing these issues as cause of non- -adherence, different approaches should be considered: set up a good physician -patient communication; promote asthma education; schedule regular appointments; simplify therapeutic regimen. It is important to promote adherence to achieve a good asthma control, and consequently a better quality of life and reduction of asthma associated costs.

Achieving asthma control in the inner city: do the National Institutes of Health Asthma Guidelines really work?

For children living in inner cities, asthma tends to be more frequent and severe. To characterize, understand, and treat children with asthma living in the inner city more effectively, the National Institute of Allergy and Infectious Diseases established an Inner-City Asthma Program in 1991. In addition, the revised National Asthma Education and Prevention Program Expert Panel 3 report was introduced with new concepts for asthma management that are now centered on asthma control. The purpose of this review is to highlight features of the National Institute of Allergy and Infectious Diseases Inner-City Asthma Consortium Asthma Control Evaluation study that enhance our knowledge regarding the application of the asthma guidelines and to provide a summary of lessons learned from that important study. We recognized that asthma symptoms and exacerbations are theoretically linked to underlying inflammation of airways but are not direct indicators of inflammation. Based on the observations from the Asthma Control Evaluation study, we were impressed that a systematic guidelines-based approach improved asthma control significantly over the course of the 1-year treatment period.

Cost-effectiveness of school-based asthma screening in an urban setting

BACKGROUND

Much has been done to promote population-based childhood asthma screening; however, concerns remain regarding its cost-effectiveness.

OBJECTIVES

To conduct a cost-effectiveness analysis of school-based asthma screening strategies.

METHODS

A 5 health state Markov approach (symptom-free, symptom, exacerbation recovery, emergency department, and hospitalization day) was used to evaluate school-based screening in a simulated population of urban elementary-age school children. Two questionnaire and 2 multistage strategies incorporating spirometry or spirometry with exercise testing were evaluated from the societal perspective by using 365 daily cycles. The outcome was 2006 dollars per quality-adjusted life year (QALY).

RESULTS

The most efficient strategy identified children with previously diagnosed but poorly controlled asthma at a cost of $150,000 per QALY (95% CI, $65,800-$318,000). Uncertainty surrounding the cost-effectiveness estimate was primarily a result of the symptom day preference weight estimate (44%), the probability of confirmation after screening (17%), the adequacy of asthma control in the population (9%), and the estimated treatment effect on symptoms (6%). Screening generated an additional 21 symptom-free day equivalents per child identified with previously diagnosed but not well controlled asthma and led to $85.55, $12.36, and $2.58 in additional screening, daily treatment, and indirect costs and $5.01 less in emergency department and hospitalization costs.

CONCLUSION

Population-based asthma screening is not cost-effective at $50,000 per QALY and has only a 20% chance of being cost-effective at $100,000 per QALY. The most efficient approach is to screen for previously diagnosed but poorly controlled asthma. Linking screening with better treatment, and long-term adherence strategies might yield future cost-effective approaches.
