Self-reported adherence, management behavior, and barriers to care after an emergency department visit by inner city children with asthma

Caregiver recall of treatment recommendations in juvenile idiopathic arthritis

OBJECTIVE

Health care providers in juvenile idiopathic arthritis (JIA) might refer to caregivers' self-report of children's treatment-related behaviors to assist in clinical decisions. However, caregivers may believe that they are adhering to treatment even though they have a different understanding of recommendations than that intended by the medical team. We examined whether caregiver recall of children's JIA treatment matched actual recommendations at baseline and 3, 6, 9, and 12 months.

METHODS

A total of 235 primary caregivers were recruited from rheumatology clinics at 2 pediatric university-based teaching hospitals in Canada. Using the Parent Adherence Report Questionnaire, caregivers indicated whether their child was prescribed medications and/or exercises. Medical charts were reviewed to determine the prescribed treatment. Level of agreement between both sets of data was then examined.

RESULTS

A total of 175 caregivers provided complete data. Mean age of the children was 10.2 years (68.6% girls); 44.6% were diagnosed with oligoarthritis. Kappa coefficients for medication represented substantial to almost perfect agreement beyond chance, with better levels of agreement at 12 months (kappa = 0.81, 95% confidence interval [95% CI] 0.68, 0.94) than at baseline (kappa = 0.61, 95% CI 0.47, 0.76). Kappa coefficients for exercise represented slight to moderate agreement beyond chance, with better agreement at 12 months (kappa = 0.44, 95% CI 0.24, 0.63) than at baseline (kappa = 0.27, 95% CI 0.08, 0.47).

CONCLUSION

Weaker agreement for the exercise regimen raises concern that caregivers may pay less attention to exercise recommendations or that these recommendations may not be easily understood.

Using discrete choice experiments to investigate subject preferences for preventive asthma medication

BACKGROUND AND OBJECTIVE

Long-term adherence to inhaled corticosteroids is poor despite the crucial role of preventer medications in achieving good asthma outcomes. This study was undertaken to explore patient preferences in relation to their current inhaled corticosteroid medication, a hypothetical preventer or no medication.

METHODS

A discrete choice experiment was conducted in 57 adults with mild-moderate asthma and airway hyper-responsiveness, who were using inhaled corticosteroid <or=500 microg/day (beclomethasone equivalent). In the discrete choice experiment, subjects evaluated 16 hypothetical scenarios made up of 10 attributes that described the process and outcomes of taking asthma medication, with two to four levels for each attribute. For each scenario, subjects chose between the hypothetical medication, the medication they were currently taking and no asthma medication. A random parameter multinomial logit model was estimated to quantify subject preferences for the aspects of taking asthma medication and the influence of attributes on medication decisions.

RESULTS

Subjects consistently made choices in favour of being able to do strenuous and sporting activities with or without reliever, experiencing no side-effects and never having to monitor their peak flow. Frequency of collecting prescriptions, frequency of taking the medication, its route of administration and the strength of the doctor recommendation about the medication were not significant determinants of choice.

CONCLUSIONS

The results of this study suggest that patients prefer a preventer that confers capacity to maximize physical activity, has no side-effects and does not require daily peak flow monitoring.

The Yes We Can Urban Asthma Partnership: a medical/social model for childhood asthma management

Pediatric asthma programs have struggled to integrate children's medical and social needs. We developed and piloted an integrated team model for asthma care for low-income children through the Yes We Can Urban Asthma Partnership. Program evaluation demonstrated increases in prescribing controller medications (p <0.05), use of action plans (p<0.001), and the use of mattress covers (p<0.001); and decrease in asthma symptoms (p<0.01). Additional changes occurred within the local system of asthma care to support ongoing efforts to improve asthma management. We conclude that pediatric asthma programs can effectively target the social and medical needs of children in a sustainable manner.

Childhood asthma in the emergency department: trends, challenges, and opportunities

Acute exacerbations of childhood asthma are frequently managed in the emergency department (ED). ED-based surveillance and intervention projects highlight the limitations and challenges of acute and chronic childhood asthma management. Because a significant number of asthmatic children currently receive and will likely continue to seek acute asthma care in the ED, provision of asthma education and initiation of controller medication therapy during the ED visit, although controversial, may contribute to improving asthma outcomes and eventually to reducing the burden of asthma on our overcrowded EDs.

Initiation of maintenance antiinflammatory medication in asthmatic children in a pediatric emergency department

BACKGROUND

Despite National Asthma Education and Prevention Program guidelines recommending the use of daily controller medication in patients with persistent asthma, less than half of children requiring emergency department treatment for asthma exacerbations are receiving antiinflammatory therapy.

OBJECTIVE

The purpose of this study was to evaluate a pediatric emergency department-based intervention designed to affect the prescribing practices of primary care physicians to better comply with national asthma guidelines. The intervention involved initiating maintenance antiinflammatory therapy in children with an asthma exacerbation who met guidelines for persistent disease but were not on antiinflammatory medications.

METHODS

Guardians of children 2 to 18 years of age presenting to the pediatric emergency department with an asthma exacerbation were asked to complete an asthma survey. Patients were classified into severity categories. Those with persistent disease not on antiinflammatory medications were given a 2-week supply of medication and were instructed to follow-up with their primary care physicians to obtain a prescription for the antiinflammatory medication. Patient adherence information was obtained through telephone calls, pharmacy claims data, and physician office records.

RESULTS

Forty-seven of 142 patients met criteria and were enrolled in the intervention. Seven patients were lost to follow-up. Of the remaining 40 patients, 28 followed-up with their primary care physician. Of these patients, 75% were continued on an antiinflammatory medication. Primary care physicians were significantly more likely to continue an antiinflammatory prescription in patients with severe persistent asthma (88.9% vs 68.4% of mild- or moderate-persistent asthmatics). Of the 28 patients who followed-up with their primary care physician, 13 had a prescription written, dispensed, and reported using the medication at the time of follow-up.

CONCLUSIONS

Pediatric emergency department physicians can successfully partner with primary care physicians to implement national guidelines for children requiring maintenance antiinflammatory asthma therapy. Patient nonadherence continues to be a significant barrier for asthma management.

The Difficult-to-Control Asthmatic: A Systematic Approach

With the judicious use of inhaled corticosteroids, beta2 agonists, and leukotriene modifiers, most patients with asthma are easily controlled and managed. However, approximately 5% of asthmatics do not respond to standard therapy and are classified as "difficult to control." 1 Typically, these are patients who complain of symptoms interfering with daily living despite long-term treatment with inhaled corticosteroids in doses up to 2,000 mug daily. Many factors can contribute to poor response to conventional therapy, and especially for these patients, a systematic approach is needed to identify the underlying causes. First, the diagnosis of asthma and adherence to the medication regimen should be confirmed. Next, potential persisting exacerbating triggers need to be identified and addressed. Concomitant disorders should be discovered and treated. Lastly, the impact and implications of socioeconomic and psychological factors on disease control can be significant and should be acknowledged and discussed with the individual patient. Less conventional and novel strategies for treating corticosteroid-resistant asthma do exist. However, their use is based on small studies that do not meet evidence-based criteria; therefore, it is essential to sort through and address the above issues before reverting to other therapy.

Utilization patterns in an asthma intervention

BACKGROUND

The National Cooperative Inner-City Asthma Study (NCICAS) tested a model of asthma management in which a master's degree-prepared social worker functioned as an asthma counselor. The NCICAS resulted in decreased symptom days and a trend toward fewer emergency department (ED) visits and hospital admissions in the intervention group compared with the control group.

OBJECTIVE

To determine whether a real-world implementation would give similar results to the NCICAS.

METHODS

Children with moderate or severe persistent asthma were enrolled in a 1-year program, the Inner-City Asthma Intervention (ICAI) program, modeled on the NCICAS. Since the program initially was not designed to be research, data were collected retrospectively. ED and hospital visits were compared 1 year before and after the intervention at 2 of the intervention sites, Children's Mercy Hospital (CMH) and Baystate Medical Center, to determine whether there was a significant change.

RESULTS

Data for 93 children from CMH and 77 from Baystate were evaluated. At CMH annual ED visits were 0.38 before, 0.42 during, and 0.41 after the intervention, whereas at Baystate ED visits were 0.09 before, 0.17 during, and 0.15 after the intervention. Mean hospitalizations at CMH increased from 0.06 before to 0.22 during and then decreased to 0.12 after (P > .05), whereas admissions at Baystate increased from 0.03 before to 0.05 during and 0.04 after the intervention.

CONCLUSIONS

Asthma self-management interventions can lead to decreases in asthma utilization under controlled circumstances. Further prospective studies are needed to determinewhether the ICAI intervention is effective under real-world conditions.

Patterns of asthma-related health care resource use in children treated with montelukast or fluticasone

OBJECTIVE

To examine the impact of controller monotherapy with montelukast or fluticasone on asthma-related health care resource use among children aged 2-14 years old.

DESIGN AND METHODS

A retrospective claims-based analysis of asthmatic children, 2-14 years old, receiving a prescription (index) for montelukast or fluticasone between January 1, 1999 and June 30, 2000 was conducted. Children were matched by age and propensity score to obtain comparable treatment groups. The propensity score was derived using patient demographics, pre-existing respiratory conditions, and asthma-related pharmacy and health service utilization (i.e. ambulatory visits, emergency department visits and hospitalizations). Claims for asthma-related emergent care and medication use were examined for the 12-month periods before and after the index prescription. Treatment group comparisons of asthma-related resource use were conducted for the total pediatric population and separately for children 2-5 years and 6-14 years. Persistent controller medication use was assessed at 6 and 12 months post-index.

RESULTS

A total of 2034 children were matched (1017 in each treatment group). Post-index rates of asthma-related resource use were similar among children treated with montelukast or fluticasone. Among children 2-5 years old, fewer emergency department visits were observed with montelukast versus fluticasone (relative risk = 0.52, 95% confidence interval [CI]: 0.28-0.96); no significant difference was observed among children 6-14 years old. No significant differences between montelukast and fluticasone cohorts in hospitalizations or rescue medication fills were noted in either age group. Evidence of at least one medication refill was significantly greater with montelukast at both 6 and 12 months post-index.

CONCLUSIONS

Similar levels of resource use were achieved by children 2-14 years initiating montelukast or fluticasone, as indicated by use of asthma-related emergent care and rescue/acute medications. Subgroup analyses suggest a differential effect of age on the relationship between treatment and asthma-related resource use, with children 2-5 years observed to have less resource use while on montelukast.

Asthma management practices among children in Georgia

BACKGROUND

Asthma self-management, the involvement of patients or their caregivers in the management of their disease, reduces healthcare visits and costs. We assessed selected asthma self-management practices among a representative sample of children in Georgia to guide statewide asthma control programs.

METHODS

A random-digit-dialed telephone survey of 2,121 households with 3,896 children 17 years of age or younger was conducted. Primary caretakers were asked about asthma and medication use of their children. Child data were weighted according to the number of telephone lines in the household and to the 2000 Georgia Census population.

RESULTS

Approximately 10 percent of children in Georgia had asthma. Among children with asthma, 30 percent did not have regular asthma checkups and 66 percent did not have a written management plan; 19 percent filled 2 or more prescriptions per year for quick-relief medicine but did not take control medication. For children with asthma for whom tobacco exposure was a known trigger, 35 percent were exposed to tobacco smoke in the home.

CONCLUSIONS

Opportunities exist to improve self-management, pharmacotherapy, and exposure to triggers for children with asthma. These data can be used to guide organizations and agencies working to reduce the burden of asthma.

A randomized clinical trial of clinician feedback to improve quality of care for inner-city children with asthma

CONTEXT

Barriers impede translating recommendations for asthma treatment into practice, particularly in inner cities where asthma morbidity is highest.

METHODS

The purpose of this study was to test the effectiveness of timely patient feedback in the form of a letter providing recent patient-specific symptoms, medication, and health service use combined with guideline-based recommendations for changes in therapy on improving the quality of asthma care by inner-city primary care providers and on resultant asthma morbidity. This was a randomized, controlled clinical trial in 5- to 11-year-old children (n = 937) with moderate to severe asthma receiving health care in hospital- and community-based clinics and private practices in 7 inner-city urban areas. The caretaker of each child received a bimonthly telephone call to collect clinical information about the child's asthma. For a full year, the providers of intervention group children received bimonthly computer-generated letters based on these calls summarizing the child's asthma symptoms, health service use, and medication use with a corresponding recommendation to step up or step down medications. We measured the number and proportion of scheduled visits resulting in stepping up of medications, asthma symptoms (2-week recall), and health care use (2-month recall).

RESULTS

In this population, only a modest proportion of children whose symptoms warranted a medication increase actually had a scheduled visit to reevaluate their asthma treatment. However, in the 2-month interval after receipt of a step-up letter, 17.1% of the letters were followed by scheduled visits in the intervention group compared with scheduled visits 12.3% of the time by the control children with comparable clinical symptoms. Asthma medications were stepped up when indicated after 46.0% of these visits in the intervention group compared with 35.6% in the control group, and when asthma symptoms warranted a step up in therapy, medication changes occurred earlier among the intervention children. Among children whose medications were stepped up at any time during the 12-month study period, those in the intervention group experienced 22.1% fewer symptom days and 37.9% fewer school days missed. The intention-to-treat analysis showed no difference over the intervention year in the number of symptom days, yet there was a trend toward fewer days of limited activity and a significant decrease in emergency department visits by the intervention group compared with controls. This 24% drop in emergency department visits resulted in an intervention that was cost saving in its first year.

CONCLUSIONS

Patient-specific feedback to inner-city providers increased scheduled asthma visits, increased asthma visits in which medications were stepped up when clinically indicated, and reduced emergency department visits.

Asthma care and management before an emergency department visit in children in western Michigan: how well does care adhere to guidelines?

OBJECTIVES

Asthma is one of the more common reasons for children's visits to the emergency departments (EDs). Many studies show that the level of asthma care and self-management in children before an ED visit for asthma is often inadequate; however, most of these studies have been conducted in the inner cities of large urban areas. Our objectives were to describe asthma care and management in children treated for asthma in 3 EDs located in an urban, suburban, or rural setting.

METHODS

We studied a prospective patient cohort consisting of children aged 2 to 17 years who presented with an acute asthma exacerbation at 3 EDs in western Michigan. An in-person questionnaire was administered to the parent or guardian during the ED visit. Information was collected on demographics; asthma history; usual asthma care; frequency of symptoms during the last 4 weeks; current asthma treatment, management, and control; and past emergency asthma care. A telephone interview conducted 2 weeks after the ED visit obtained follow-up information. The 8 quality indicators of asthma care and management were defined based on recommendations from national guidelines.

RESULTS

Of 197 children, 70% were enrolled at the urban site, 18% at the suburban site, and 12% at the rural site. The average age was 7.9 years; 60% were male, and 33% were black. At presentation, nearly half (46%) of the children had mild intermittent asthma, 20% had mild persistent asthma, 15% had moderate persistent asthma, and 19% had severe persistent asthma. One quarter of the children had been hospitalized for asthma, and two thirds had at least 1 previous ED visit in the past year. At least 94% had health insurance coverage and 95% reported having a primary care provider. Less than half of the children had attended at least 2 scheduled asthma appointments with their regular asthma care provider in the past year. Although only 5% of the subjects reported that the ED was their only source of asthma care, at least 30% reported that they always went directly to the ED when they needed urgent asthma care. Only 3 in 5 children possessed either a spacer or a peak-flow meter, whereas approximately 2 in 5 reported having a written asthma action plan. Among those with persistent asthma, there was considerable evidence of undertreatment, with 36% not on either an inhaled corticosteroid or a suitable long-term control medication. Only 20% completed a visit with their regular asthma care provider within 1 week of their ED visit.

CONCLUSIONS

Despite very high levels of health care coverage and access to primary care, the overall quality of asthma care and management fell well short of that recommended by national guidelines.

Emergency department allies: a controlled trial of two emergency department-based follow-up interventions to improve asthma outcomes in children

OBJECTIVE

We sought to study the impact of emergency department (ED)-based intensive primary care linkage and initiation of asthma case management on long-term, patient-oriented outcomes for children with an asthma exacerbation.

METHODS

Our study was a randomized, 3-arm, parallel-group, single-blind clinical trial. Children aged 2 through 17 years treated in a pediatric ED for acute asthma were randomly assigned to standard care (group 1), including patient education, a written care plan, and instructions to follow up with the primary care provider within 7 days, or 1 of 2 interventions. Group 2 received standard care plus assistance with scheduling follow-up, while group 3 received the above interventions, plus enrollment in a case management program.

OUTCOMES

The primary outcome was the proportion of children having an ED visit for asthma within 6 months. Other outcomes included change in quality-of-life score and controller-medication use.

RESULTS

Three hundred fifty-two children were enrolled; 78% completed follow-up, 69% were black, and 70% had persistent asthma. Of the children, 37.8% had a subsequent ED visit for asthma, with no difference among the treatment groups (group 1: 38.4%; group 2, 39.2%; group 3, 35.8%). Children in all groups had a substantial, but similar, increase in their quality-of-life score. Controller-medication use increased from 69.4% to 81.4%, with no difference among the groups.

CONCLUSION

ED-based attempts to improve primary care linkage or initiate case management are no more effective than our standard ED care in improving subsequent asthma outcomes over a 6-month period.

Delivering tailored asthma family education in a pediatric emergency department setting: a pilot study

OBJECTIVE

Many children are brought to the pediatric emergency department (ED) with acute asthma symptoms. Emergency asthma care is costly, and many ED visits may be preventable. Families often do not have written asthma action plans and lack asthma self-management skills. This study tests a tailored self-management intervention delivered in the ED for families of children with asthma. The primary hypotheses were that the intervention group would have greater confidence to manage asthma 14 days postintervention and more well-asthma visits and fewer urgent care/ED visits at 9 and 12 months.

METHODS

This randomized intervention/usual-care study was part of a larger ED asthma surveillance project in 4 urban pediatric ED sites. Asthma educators used a computer-based resource to tailor the intervention messages and provide a customized asthma action plan and educational summary. Children with acute asthma were enrolled during an ED visit, and follow-up telephone interviews were conducted during the next 9 months. The ED clinician classified the child's acute and chronic severity.

RESULTS

To date, 464 subjects aged 1 to 18 years have been enrolled. The ED clinicians reported that 46% had intermittent and 54% had persistent chronic severity with 51% having mild acute severity episodes. The confidence level to prevent asthma episodes and keep them from getting worse was significantly higher in the intervention group at 14 days postintervention. More subjects in the intervention group reported well-asthma visits by 9 months. Return ED visits were significantly lower in the intervention group in those with intermittent asthma. Twelve-month follow-up is in process.

CONCLUSIONS

The tailored ED self-management intervention demonstrates significant effects on caregiver self-confidence and well-visit follow-up. Additional evaluation is needed to determine what impact this intervention has long-term.

Predictors of primary care follow-up after a pediatric emergency visit for asthma

OBJECTIVE

Prior studies have reported low rates of follow-up with a primary care provider (PCP) after emergency department (ED) treatment for asthma. We sought to identify predictors associated with PCP follow-up.

METHODS

As part of a randomized trial we surveyed parents of children aged 2-18 years being discharged after ED asthma treatment. Parents described their child's asthma history and perceived benefits and barriers to making a PCP follow-up visit. Bivariate tests and multivariable logistic regression were used to determine association with completion of a follow-up visit within 4 weeks of the ED visit.

RESULTS

A total of 278 subjects (N = 278) were enrolled; 55% saw their PCP within 4 weeks of the ED visit. Baseline factors that were associated with an increased likelihood of follow-up included a recent hospitalization, more than one ED visit for asthma in the past year, the parent's assessment that the child has "very severe" asthma, and current daily use of a controller medication. Parental beliefs that taking daily asthma medications and finding out about the causes of asthma attacks were very important and were also associated with increased PCP follow-up. Parents were less likely to follow up if they reported a lack of convenient appointments or prolonged waits in the PCP office. A multivariable model including clinical factors, parental beliefs, and the study intervention predicted the likelihood of follow-up.

CONCLUSIONS

Parental beliefs about asthma severity, the benefits of controlling asthma, and organizational barriers to seeing a PCP were associated with follow-up after a pediatric ED visit for asthma.

Randomized controlled trial of emergency department interventions to improve primary care follow-up for patients with acute asthma

OBJECTIVE

Emergency department (ED) visits for asthma are frequent and may indicate increased morbidity and poor primary care access. Our objective was to compare the effect of two interventions on primary care follow-up after ED treatment for asthma exacerbations.

METHODS

We performed a randomized controlled trial of patients 2 to 54 years old who were judged safe for discharge receiving prednisone, and who were available for contact at 2 days and 30 days. Patients were excluded if they were previously enrolled or did not speak English. Patients received usual discharge care (group A); free prednisone, vouchers for transport to and from a primary care visit, and either a telephone reminder to schedule a visit (group B); or a prior scheduled appointment (group C). Follow-up with a primary care provider for asthma within 30 days was the main outcome. Secondary outcomes were recurrent ED visits, subsequent hospitalizations, quality of life, and use of inhaled corticosteroids 1 year later.

RESULTS

Three hundred eighty-four patients were enrolled. Baseline demographics, chronic asthma severity, and access to care were similar across groups. Primary care follow-up was higher in group C (65%) vs group A (42%) or group B (48%) [p = 0.002]. Group C intervention remained significant (odds ratio, 2.8; 95% confidence interval, 1.5 to 5.1) when adjusted for other factors influencing follow-up (prior primary care relationship, insurance status). There were no differences in ED, hospitalizations, quality of life, or inhaled corticosteroid use at 1 year after the index ED visit.

CONCLUSION

An intervention including free medication, transportation vouchers, and appointment assistance significantly increased the likelihood that discharged asthma patients obtained primary care follow-up but did not impact long-term outcomes.

Health disparities and differences in asthma: concepts and controversies

Asthma is one of the most common respiratory diseases, with immense social impact. Despite best efforts, asthma prevalence, morbidity, and mortality are increasing in the United States. This is especially the case in select communities which suffer an excess burden of asthma. Studying these groups and attempting to ameliorate the disease burden they suffer has an important moral and social imperative. It also may lend important insight into the complex factors that contribute to asthma outcomes. The factors that affect asthma interact in a complicated manner and require a comprehensive approach that addresses each of them. However, pursuing health disparities research is controversial, and important ethical and operative considerations need to be made by those to engage in health disparities research.

Emergency physicians' prescribing of asthma controller medications

OBJECTIVES

To determine the frequency with which emergency department (ED) physicians prescribe long-term controller medications (LTCMs) for children with asthma, to assess ED physicians' awareness of and level of agreement with national guidelines for LTCM use, and to identify criteria ED physicians use to prescribe LTCMs and barriers to the use of LTCMs.

METHODS

A survey of all physician members of the American Academy of Pediatrics Section on Emergency Medicine who provide care for children in an ED was performed.

RESULTS

Surveys were returned by 391 (50%) of 782 physicians. The majority (80%) indicated that fewer than one half of children with persistent asthma were using LTCMs on ED arrival. Although 99% believe that children with persistent asthma should be treated with LTCMs, <20% provide LTCMs for the majority of such children at ED discharge. For 49%, the main reason for not prescribing these medications was the belief that this was the role of the primary care provider or asthma specialist. Practice setting, prior training, and annual patient volume were not associated significantly with prescribing LTCM. Patient's age and likelihood of compliance and physician's belief in efficacy and concerns about adverse effects were not important criteria in the decision to begin LTCM.

CONCLUSIONS

ED physicians often encounter children with persistent asthma who are not receiving LTCMs, they believe in the efficacy and safety of LTCMs, and they think that children with persistent disease should be treated with LTCMs, but they prescribe LTCMs infrequently.

Contrast of pediatric asthma management approaches in a multicultural and collectivistic population

BACKGROUND

Although asthma is the most prevalent chronic illness in childhood and affects approximately 9 million children, the management approaches used by practitioners may not be efficient from the perspective of families. Clinicians often maintain their usual customs of practice, and the context of the clinical encounter is defined in terms of an individual illness management. In collectivistic and multiethnic settings, the extended kin group or extended family shares responsibility for illness management. The goal of this study is to describe health care providers' strategies to manage children with asthma in a multicultural and collectivistic cultural context.

METHODS

Data were obtained through semistructured in-depth practitioner interviews. Western-trained and traditional practitioners participated.

RESULTS

Narrative analysis strategies produced two major themes: 1) fix the asthma and 2) making connections. Practitioners who perceived their responsibility to fix the asthma (make things physiologically normal) often ran into constraints with dealing with the extended family group. Other practitioners who used strategies of making connections often capitalized on the assistance of others to problem-solve the asthma management.

CONCLUSION

In terms of asthma management, the barriers most frequently reported by practitioners were related to the sociocultural and physical environment. There may be vast differences in asthma management approaches for populations from collectivistic cultural orientation.

Impact of asthma intervention in two elementary school-based health centers in the Bronx, New York City

This study examines healthcare utilization over time in Bronx, New York schoolchildren with asthma who were previously identified via parent surveys in six elementary schools. Four of the schools have on-site school-based health centers (SBHCs), and two do not have on-site health services (control schools). At baseline, we reported an asthma prevalence of 20%, and high rates of emergency department (ED) use (46%) in the previous year. To determine if asthma morbidity (specifically, ED use, community provider use, and hospitalizations for asthma) could be reduced by incorporating an aggressive intervention at two schools with SBHCs, we prospectively followed children for up to 3 years. Parents were scheduled for interviews every 6 months, and were queried about their children's use of health services for asthma in the prior 6 months. In multivariate models, children in the two intervention SBHC schools were less likely to have visited a community provider for asthma (relative rate ratio, 0.52; 95% confidence interval (CI), 0.30-0.88) or an emergency department for asthma (odds ratio, 0.44; 95% CI, 0.14-1.38; P = 0.059) in the prior 6 months compared to children attending control schools. There was no difference in community provider use or emergency department use for asthma between children attending nonintervention SBHCs and control schools. However, school type did not affect asthma hospitalization rates, which declined in all groups. Our findings support the effectiveness of aggressive school-based asthma services provided by SBHCs to reduce asthma morbidity and complement community health services.

Parental beliefs about medications and medication adherence among urban children with asthma

BACKGROUND

Although national guidelines recommend controller medications for children with persistent asthma, adherence is poor. Prior studies have begun to explore parental beliefs regarding controller asthma medications and their effect on adherence.

OBJECTIVE

To describe parental beliefs about controller medications among a community-based sample of urban children with persistent asthma and to examine the relationship between parental beliefs and adherence.

DESIGN/METHODS

Parents of 150 children with asthma completed a telephone survey as part of a larger asthma intervention. Parents of children using controller asthma medications were included in this study. A previously validated Beliefs About Medications Questionnaire (BMQ) was used, which included two subscales: necessity and concern. The relationship between parental beliefs about medications and medication adherence was assessed using bivariate linear regression and multivariate statistics.

RESULTS

This study included 67 children with parental report of controller medication (54% male, 61% African American, 69% Medicaid). Overall, 75% of parents strongly believed that their child's medications were necessary for their health and 34% had strong concerns about the medications. Only 22% of parents reported being completely adherent with medications. Parents with greater concern about medications were more likely to have poor adherence (P < .05). In a multivariate analysis, including both BMQ subscales and asthma severity, concern about medications significantly predicted poor medication adherence (P = .03).

CONCLUSIONS

Parental concerns about controller medications were associated with poor medication adherence for this population of urban children with asthma. These findings highlight the importance of addressing parental concerns at the time of medication prescription.

Self-reported antibiotic compliance: Emergency department to general practitioner follow up

BACKGROUND

General practitioner (GP) follow up is important in the management of patients who are discharged from an ED.

OBJECTIVES

To determine the antibiotic compliance and GP follow-up compliance rates in a population of patients seen and discharged from the ED with an antibiotic prescription. To test the hypothesis that the ability to nominate a GP is associated with improved antibiotic and GP follow-up compliance.

DESIGN

A prospective cohort study enrolling consecutive adults who were discharged from the ED with antibiotic prescriptions over a 3 month period. Patients were divided into those who nominated a GP at the time of ED presentation and those who did not. Two weeks after enrollment, patients were contacted and asked standardized questions regarding compliance.

RESULTS

In total, 123 patients were enrolled into the study. Of patients 76% were able to nominate a GP upon ED presentation. Analysis revealed that those patients who were able to nominate a GP had better compliance to follow up instructions (85 vs 44%, P < 0.01) and improved antibiotic compliance (99 vs 88%, P = 0.01).

CONCLUSION

The majority of patients who were seen and discharged from the ED with an antibiotic prescription were able to nominate a GP and this was associated with improved follow-up compliance and antibiotic compliance. Improving follow-up compliance and thus the quality of patient care would involve identifying those patients who present to the ED who are unable to nominate a GP.

Group discussions with parents have long-term positive effects on the management of asthma with good cost-benefit

AIM

To investigate if an intervention with extra information and support in a group setting to parents of preschool children could improve adherence and clinical outcome.

METHODS

This is a controlled, prospective study where the parents of 60 newly diagnosed preschool asthmatic children aged 3 mo-6 y were randomized to either a control group or to an intervention that consisted of four group sessions in close connection with the diagnosis. The basic education on asthma and the written treatment plan were the same in both groups. The outcome measures were questionnaires to the parents and classification of the children according to symptoms and medication. The adherence rate and the burden of asthma were calculated with the help of diaries and weighing of the MDIs used between 12 and 18 mo after inclusion.

RESULTS

The follow-up rate was 85% after 18 mo. The parents' presence in the sessions was around 70%, with no gender difference. The parents' view on adherence issues improved significantly in the intervention group. In the control group, 30% had poor adherence compared to 8% in the intervention group (p=0.015). Both the parents and the paediatricians underestimated the number of children with poor adherence. The children in the intervention group had significantly fewer exacerbation days during the last 6 mo-2.1 compared to 3.9 d/child-although they had lower inhaled steroid doses after 18 mo. An economic calculation showed that the intervention was profitable.

CONCLUSION

This intervention resulted in an improvement in the parents' view on adherence, in the measured adherence rates and in the clinical outcome.

Presentation and treatment of asthma among native children in southwest Alaska delta

Our objective was to determine if a different presentation of asthma among Eskimo children in southwest Alaska influenced treatment for asthma. Data regarding symptoms, medication use, and hospitalization were obtained from the medical records of 58 Eskimo children diagnosed with asthma. Half of the children also had a diagnosis of chronic lung disease (CLD), and 57% had a history of allergies. CLD was associated with significantly more visits for wheeze (P=0.02), asthma (P <0.005), and lower respiratory tract illnesses (P <0.005), and a greater incidence (P <0.005) and frequency (P <0.005) of hospitalizations. Allergy status showed no similar relation with utilization of health services. Inhaled corticosteroids were prescribed for a minority (38%) of these asthmatic children. Allergic children tended to be more likely to receive inhaled steroids, and they received significantly more prescriptions for inhaled steroids compared to children without allergies. Those with CLD only were no more likely to receive inhaled steroids than other children, despite their higher incidence of hospitalization. Although the proportion of children with CLD or allergy did not differ significantly by village, there were significant regional differences in healthcare utilization and medication use. In conclusion, while CLD was the primary determinant of healthcare utilization among these native children with asthma, only allergic children with CLD were more likely to receive inhaled steroids.

Effect of education on school-age children's and parents' asthma management

ISSUES AND PURPOSE

Asthma affects 7.4% of school-age children, with poor children or members of ethnic minorities disproportionately affected.

DESIGN AND METHODS

A quasiexperimental, year-long pilot study tested the effectiveness of an intervention that included school-based small-group education for children with home-based education for parents. Pretest and two posttest measures were collected.

RESULTS

Forty-four families completed the study (41% African American, 36% European American, 23% Mexican American), with 46% coming from poor or working-class families. Asthma management in the treatment group was lower than the comparison group at baseline, but improved significantly at 6 months and stabilized at 12 months, a trend that was most pronounced among the poorer children.

PRACTICE IMPLICATIONS

Improvements in asthma management point to the need for ongoing asthma education to address learning needs of the children and families.

Parents' Reports of Barriers to Care for Children With Special Health Care Needs: Development and Validation of the Barriers to Care Questionnaire

OBJECTIVE

To describe the development and validation of the Barriers to Care Questionnaire (BCQ).

METHODS

The 39-item BCQ was developed through review of the literature, focus groups, and cognitive interviews of Spanish- and English-speaking parents of children with chronic health conditions. Barriers to care are conceptualized as a multidimensional construct consisting of pragmatics, health knowledge and beliefs, expectations about care, skills, and marginalization. The BCQ was field tested in 3 samples of children with special health care needs (CSHCN).

RESULTS

Response rate for the field test was 77.2%. There were minimal missing data (0.08%), no floor effects, and minimal ceiling effects (3.8%, total scale). Internal consistency reliability (alpha) for the BCQ total scale was.95 and subscale alpha ranged from.75 to.91. The BCQ total scale and subscales correlated in the expected direction with validated measures of primary care characteristics and health-related quality of life. BCQ scores were higher (fewer barriers) for children with a primary care physician and for those who reported no problems getting care or foregone care.

CONCLUSION

The BCQ is a feasible, reliable, and valid instrument for measuring barriers to care for CSHCN. Its use may inform efforts to support consumer choice, enhance provider accountability, and spur quality improvement.

A review of the effects of impermeable bedding encasements on dust-mite allergen exposure and bronchial hyper-responsiveness in dust-mite-sensitized patients

BACKGROUND

Sensitization and exposure to dust-mite antigens are causative factors in the development and exacerbation of asthma. Impermeable bedding encasements are considered a first-line treatment to reduce dust-mite antigen exposure in clinical asthma-management guidelines. Public-health recommendations for environmental asthma treatments should be based on the weight of evidence supporting the reliability of environmental interventions so that uncertainties regarding their effectiveness can be accurately communicated to patients, and so that limited public-health resources can be most effectively utilized.

OBJECTIVE

To evaluate the strength of a clinical-trial evidence supporting the efficacy of bedding encasements as an asthma treatment.

METHODS

A narrative review was conducted of all clinical trials involving bedding encasement for the treatment of asthma. Collective statistical analyses were also performed to characterize the quantitative effect of bedding encasement on dust-mite allergen exposure and bronchial hyper-responsiveness (BHR) when used by asthma patients.

RESULTS

Over 30 clinical trials were reviewed. Of those studies reporting adequate exposure and BHR results, four reported significant reduction in dust-mite allergen exposure and concomitant BHR reduction in active-treatment groups using bedding encasements. In 10 studies, mite-allergen exposure was reportedly decreased during the study, but BHR was not changed in the active-treatment group or was reduced to a similar degree in the active-treatment and control groups. Five other studies reported a lack of significant effect of the intervention on exposure and BHR. Collective paired analyses found that the effect of bedding encasement on allergen exposure and BHR tended toward only a modest, non-significant improvement. Collectively, effects of bedding encasement on BHR and dust-mite allergen exposure were modestly correlated only when the baseline exposure was above 2 microg Type 1 antigen per gram settled dust.

CONCLUSION

Although bedding encasement might be an effective asthma treatment under some conditions, when implemented in clinical trials by asthma patients, its effectiveness is inconsistent and appears to be, at best, modest. Therefore, its significance as a reliable asthma management modality for any individual asthma patient is uncertain. Where resource constraints are significant, targeting the use of variably effective interventions such as bedding encasements toward those patient sub-populations most likely to derive substantial benefit may gain the largest net public-health benefit.

Understanding pediatric inner-city asthma: an explanatory model approach

Explanatory models (EMs) for asthma among inner-city school-age children and their families were examined as a means of better understanding health behaviors. Children and parents were interviewed about their concepts of asthma etiology, asthma medications, and alternative therapies. Drawings were elicited from children to understand their beliefs about asthma. Nineteen children with 17 mothers from a variety of cultural backgrounds were interviewed. Among children, contagion was the primary EM for asthma etiology (53%). Twenty-five percent of children reported fear of dying from asthma, while fear of their child dying from asthma was reported by 76% of mothers. Mothers reported a variety of EMs, some culturally specific, but the majority reported biomedical concepts of etiology, pathophysiology, and triggers. Although 76% of mothers knew the names of more than one of their children's medications, 47% thought their child's medications all had similar functions. Thirty-five percent of families used herbal treatments and 35% incorporated religion into asthma treatment. Seventy-one percent of families had discontinued medications and 23% reported currently not giving anti-inflammatory medication. Reasons for discontinuing daily medications included fears of unknown side effects (53%), addiction (18%), tachyphylaxis (18%), and feeling that their child was being given too much medicine (23%). The traditional focus of asthma education is not sufficient to ensure adherence. Asthma education for children should address their views of etiology and fears about dying from asthma. Conversations with parents about their EMs and beliefs about medications and alternative therapies could assist in understanding and responding to parental concerns and choices about medications and help achieve better adherence.

Association between outpatient follow-up and pediatric emergency department asthma visits

BACKGROUND

The National Heart, Lung, and Blood Institute (NHLBI) guidelines recommend that patients receive a follow-up outpatient asthma visit after being discharged from an emergency department (ED) for asthma.

OBJECTIVE

To measure the frequency of follow-up outpatient asthma visits and its association with repeat ED asthma visit.

DESIGN

We conducted a retrospective cohort study of children with asthma using claims data from a university-based managed care organization from January 1998 to October 2000. We performed a multivariate survival analysis using Cox proportional hazards model to determine the effect of follow-up outpatient asthma visits on the likelihood of a repeat ED asthma visit, after controlling for severity of illness, patient age, gender, insurance, and the specialty of the primary care provider.

RESULTS

A total of 561 children had 780 ED asthma visits. Of these, 103 (17%) had a repeat ED asthma visit within 1 year. Almost two-thirds of children (66%) did not receive outpatient follow-up for asthma within 30 days of an ED asthma visit. Outpatient asthma visits within 30 days of an ED asthma visit are associated with an increased likelihood (relative risk = 1.80; 95% confidence interval 1.19, 2.72) for repeat ED asthma visits within 1 year.

CONCLUSIONS

Most patients do not have outpatient follow-up after an ED asthma visit. However, those patients that present for outpatient follow-up have an increased likelihood for repeat ED asthma visits. For the primary care provider, these outpatient follow-up visits signal an increased risk that a patient will return to the ED for asthma and are a key opportunity to prevent future ED asthma visits.

Transitioning youths into care: linking identified HIV-infected youth at outreach sites in the community to hospital-based clinics and or community-based health centers

PURPOSE

To describe and analyze the process of transitioning HIV-infected youths from the point of HIV diagnosis into HIV treatment. Rather than simply offering HIV positive youths a list of referrals, the youth-focused SPNS grantees (AWAC) found it vital that youths were immediately assisted with linkage to a medical provider.

METHODS

From February 1997 to December 2000, 107 identified HIV-infected youths from the five adolescent SPNS projects were surveyed on needs and barriers. The time interval between HIV testing and youth linkage to care was also noted.

RESULTS

Nine percent of youth reported perceived barriers to accessing health care. Perceived needs were identified as Mental Health (44.9%; n = 48); Alcohol and drug treatment (14%; n = 15); transportation to health care settings (40.2%; n = 43); and housing (46.7%; N = 50). At sites tracking linkage to care, the time of being transitioned into a medical setting ranged from 5 to 55 days (average 26 days).

CONCLUSIONS

The period of transitioning identified HIV-infected youths into care can be reduced from 1-5 years to as short as 5-55 days. Success with linking these youth to care involves establishing a series of contacts at outreach sites wherein program staff seeks to build trusting relationships with youths, is able to track these youths and identify and address perceived needs.

Barriers to anti-inflammatory medication use in childhood asthma

OBJECTIVES

To identify parental barriers to anti-inflammatory medication use and to develop an instrument for use in research and health care settings to identify at-risk populations.

METHODS

Instrument development consisted of 4 phases: 1) gaining the professional perspective (N = 8 experts in asthma management), 2) gaining the perspective of parents of children with asthma (qualitative interviews with 21 parents), 3) instrument pretesting and refinement (N = 133 parents), and 4) determining the instrument's psychometric properties. Study participants were diverse in race, socioeconomic status, and the child's illness severity. The final instrument consisted of 51 questions in 5 domains (nature of disease, cause, ideas about medications, treatment expectations, and health care provider relationship).

RESULTS

The final instrument exhibited strong reliability (Cronbach alpha =.87) and validity. Significant barriers to appropriate anti-inflammatory medication use were parents' diminished treatment expectations and fears about anti-inflammatory medications. Minority families were more likely than white families to view asthma as unpredictable and uncontrollable (P =.01) and to have negative attitudes toward anti-inflammatory medications (P =.004). Eight questions were significantly correlated with a suboptimal medication regimen and may serve as a "quick screen" for potential nonadherence in clinical settings.

CONCLUSIONS

Diminished treatment expectations and negative attitudes toward anti-inflammatories may be powerful predictors of nonadherence to medications.

Do school-based health centers provide adequate asthma care?

School-based health centers (SBHCs) are increasingly charged with providing primary care services including asthma care. This study assessed SBHC provider adherence to the National Heart, Lung, and Blood Institute (NHLBI) asthma care guidelines and the association among provider adherence, patient characteristics, and asthma outcomes. A cross-sectional study design was used to assess SBHC chart data from 415 children with asthma attending four inner-city elementary schools (K-5) in the Bronx, NY. Asthma symptoms, peak flow use, follow-up visits, and referrals to asthma specialists were documented in the charts of 60%, 51%, 22%, and 3% of subjects, respectively. Thirty-three percent of charts had SBHC clinician-documented severity classifications, of which 70% had appropriate medications prescribed. Asthma education and an asthma plan were documented in 18% and 10% of charts, respectively. Environmental triggers and tobacco exposures were documented in 71% and 49% of charts, respectively. Older children (> 8 years) were more likely to have documentation of peak flow use for asthma management, asthma education, follow-up visits, and written asthma plans, whereas younger children (< 8 years) were more likely to miss more days of school (all p < .05). Overall, provider adherence to NHLBI guidelines was inadequate, with adherence somewhat better for older children.

Children's use of emergency departments for asthma: persistent barriers or acute need?

Our objective was to explore, in a predominantly Latino inner-city population, why caregivers bring their children with asthma to the ED (emergency department). We conducted bilingual parent surveys and medical chart abstractions of a consecutive ED sample consisting of 234 children with asthma (69% Latino; 54% Spanish-speaking) and their caregivers. Outcome measures included: (1) the acute need for ED services based on objective physiological measures, (2) the extent to which these children experienced barriers to quality primary care for asthma before the ED visit, and (3) the relative importance caregivers assigned to worsening symptoms versus perceived barriers to non-ED care when deciding to bring their child to the ED. Most children had moderate or severe asthma attacks. In the prior month, only 33% went to a primary care provider, 83% had used a bronchodilator, and 63%, an age-appropriate spacer device. Seventy-five percent of caregivers cited perceived acute need, instead of barriers to primary care, as the most important reason for using the ED. This perception of acute need was associated with moderate or severe asthma attacks according to objective physiological measures, after controlling for health and sociodemographic characteristics. Children with asthma who use the ED encounter barriers to primary care, but caregivers' perception of acute need--validated by independent measures of attack severity--dominates caregivers' decision to use the ED. Ensuring continuity of care for children with asthma would involve not only improving various aspects of access to and quality of primary non-ED care--including parent education about early recognition and treatment of asthma attacks--but also providing families with practical low-cost alternatives for 24-hour care and assuring linkages between the ED and sources of primary care.

Home asthma management for rural families

ISSUES AND PURPOSE

To assess home asthma management among rural families with a school-age child who has asthma.

DESIGN AND METHODS

Exploratory analysis of baseline data of a tri-ethnic sample of rural families with school-age children who have asthma.

RESULTS

Parents and children enact a moderate amount of asthma management behaviors. Preventive behaviors were correlated with the Asthma Behavior Inventory and treatment behaviors were correlated with the child's asthma severity. Factors that could affect asthma management include no insurance, no visits to providers in 12 months, or no asthma medications.

PRACTICE IMPLICATIONS

Nurses must use every contact with families to assess their asthma management and availability of resources, and to determine the fit between asthma severity and the asthma management plan.

The use of anti-asthmatic medications among pediatric patients in Taiwan

PURPOSE

To describe the use of anti-asthma drugs in Taiwanese pediatric patients.

METHODS

Using the data from the database of Bureau of National Health Insurance, we analyze the patterns and extent of medication use among asthma patients less than 18 years old. Drugs were classified according to the Anatomical Therapeutic Chemical (ATC) Classification system.

RESULTS

Data on a total of 2,90,467 children were included in the study. Overall, patients were treated more frequently with oral medications. 69.43 and 40.24% of patients were using oral beta-agonists (OBAs) and methylxanthines respectively. Monotherapy with OBAs was the most popular regimen, accounting for 13.70% of the total prescriptions studied. Only 6.70% of patients were taking inhaled corticosteroids (ICSs). During the studied period, users of ICSs were using an average of 1.65 canisters.

CONCLUSIONS

The current practices of asthma management in Taiwan fall short of the goals stated in international guidelines. Anti-inflammatory agents were being underused in Taiwanese pediatric patients.

A potential pitfall in provider assessments of the quality of asthma control

BACKGROUND

Pediatricians elicit information about asthma control from parents to help formulate management plans. If parents of children with significant asthma symptoms inappropriately indicate good control, physician recommendations may not be optimal. We examined whether a single general question about asthma control might lead to inaccurate assessment of severity.

DESIGN/METHODS

Children 3-7 years of age who met the National Heart, Lung, and Blood Institute (NHLBI) criteria for mild persistent to severe asthma were identified from 40 urban schools. A phone survey of their parents provided demographic information, symptom frequency, medication use, and general interpretation of their child's asthma control. Chi-square analyses compared the parent's general interpretation of control with demographic characteristics and measures of asthma severity.

RESULTS

One hundred sixty of 224 eligible children participated in this study. Seventy-eight percent were described as in good asthma control. General assessment of asthma control did not vary by demographic characteristics. Parents were as likely to describe children with daily asthma symptoms in good control as they were to describe children with less frequent symptoms in good control. Parents were less likely to report good control in children using daily rescue medications when compared with children with less frequent medication use (65% vs 82%, P =.03), but the majority of children in both groups was described as having good control.

CONCLUSIONS

Most parents underestimated the severity of their child's asthma and reported good control with their global assessment. Parents frequently reported good control even when the children had daily asthma symptoms. Pediatricians should ask about specific asthma symptoms during patient encounters because a global question about asthma control likely will result in underestimations of asthma severity.

Scheduled follow-up after a pediatric emergency department visit for asthma: a randomized trial

OBJECTIVES

Follow-up with a primary care provider (PCP) is recommended after an emergency department (ED) visit for asthma to assess clinical status and develop a management plan to improve future care. However, previous ED-based studies of urban children with asthma have reported low follow-up rates. The objective of this study was to determine whether scheduling an appointment at the time of an ED visit improves PCP follow-up for urban children. A secondary goal was to assess the effect of this intervention on short-term health outcomes and the use of recommended preventive controller medications.

METHODS

This randomized trial enrolled a convenience sample of children who were 2 to 18 years old and discharged after treatment for acute asthma in an urban children's hospital ED. Both intervention and control subjects were instructed to follow up with their PCP within 3 to 5 days. Study staff assisted intervention subjects to call their PCP from the ED and schedule an appointment. When follow-up could not be scheduled, assistance continued after ED discharge by telephone until an appointment date was confirmed. Study outcomes included PCP visits, asthma-related morbidity, and daily use of preventive medication 4 weeks after the ED visit. Outcomes were assessed by telephone interview and confirmed by PCP record review.

RESULTS

A total of 278 eligible subjects were enrolled over 8 months; intervention and control groups were similar by demographic variables and PCP type as well as by asthma history, symptoms, and previous medication use. Only 38% of subjects reported using a daily controller medication, although 70% described persistent asthma symptoms for which these are recommended. For the intervention group, follow-up appointments were successfully obtained during the ED visit for 24% of subjects; when unsuccessful, a median of 3 telephone calls (range: 1-14) were needed to confirm that an appointment had been scheduled. During the 4 weeks after the ED visit, intervention subjects were more likely than controls to follow up with their PCP (64% vs 46%; relative probability for follow-up: 1.4; 95% confidence interval: 1.1-1.7). Study groups did not differ in return ED visits, missed school or work, or the percentage reporting daily use of a controller medication (58% vs 54%) 4 weeks after the ED visit. The median time to the next PCP visit was shorter among intervention subjects (13 vs 54 days).

CONCLUSIONS

Scheduling an appointment after an ED visit increased the likelihood that urban children with asthma would follow up with a PCP. An appointment could not be obtained during the ED visit for most children. Other interventions are needed to improve linkage between ED and primary care for asthma and to improve the use of controller medications.

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

OBJECTIVE

To assess the extent to which caregivers and their child's physician agree about the prescribed asthma medication regimen and evaluate factors associated with medication concordance.

METHODS

A cross-sectional, descriptive survey was administered to 318 caregivers of inner-city children with asthma, aged 5 to 12 years, and their caregiver-identified primary care physician at elementary schools and participants' homes. Concordance between caregiver- and physician-reported controller medication prescription was measured.

RESULTS

Only 42% of physicians and 32% of caregivers reported a controller medication prescription (78% agreement, kappa = 0.54; 95% confidence interval: 0.45-0.63) despite that 73% of the children were rated by their caregiver as currently experiencing persistent asthma symptoms. When the physician reported a controller prescription, 38% of the caregivers denied use of a controller. Having a course of oral steroids in the past year (chi(2) = 9.85) and positive caregiver beliefs toward asthma care (chi(2) = 18.40) were associated with caregiver-physician concordance. Multivariate analysis found that when caregivers had high Asthma Beliefs Scale summary scores versus low scores, they were almost 10 times as likely to be concordant with the physician (odds ratio: 9.76; 95% confidence interval: 2.85-33.46).

CONCLUSIONS

Our data support previous reports of physician underprescribing of controller medication among inner-city children. However, even when prescribed by a physician, more than one third of caregivers did not report a controller prescription, and this discordance was related to caregivers' beliefs about treatment. Efforts to improve physician adherence to asthma guidelines will not result in proper treatment unless caregiver-physician communication about asthma therapy is improved.

Factors associated with emergency department use in asthma: acute care interventions improving chronic disease outcomes

OBJECTIVE

To provide a literature review of the factors associated with childhood asthma-related emergency department (ED) visits and to identify elements of effective ED interventions that reduce the frequency of childhood ED visits while increasing primary health care utilization.

DATA SOURCE

English Medline articles from 1990 that cross-referenced with the terms asthma, emergency, intervention, pediatric, and/or acute care. Experts in the field of allergy and asthma were also consulted.

STUDY SELECTION

Childhood asthma interventions in the ED.

RESULTS

Factors associated with childhood asthma-related ED visits include being impoverished, being exposed to allergens, receiving Medicaid or lacking insurance, being noncompliant with self-management skills, and having an African-American heritage. Other minorities may also be at risk, but further investigation is required to determine the extent. Attempts to link the patient to primary health care by the ED staff resulted in increased adherence to followup care.

CONCLUSIONS

The ED provides an opportunity to help patients and families deal with asthma to improve their quality of life. Further, current studies demonstrate that the ED is an appropriate setting for an intervention that links the patient back to the primary health care provider. More research is needed on the appropriate educational messages to be delivered in ED. Also, barriers to followup care and regular use of a primary health care provider need to be identified so that future intervention designs can address these issues.

An individualized intervention to improve asthma management among urban Latino and African-American families

We hypothesized that an educational intervention based on a readiness model would lead to improved health outcomes among patients with asthma. Within a randomized control design in an urban Latino and African-American community we conducted an intensive three-month pediatric intervention. A Family Coordinator provided patient education based on a readiness-to-learn model, and facilitated improved interactions between the patient and the doctor. Family education addressed the most basic learning needs of patients with asthma by improving their perception of asthma symptom persistence using asthma diaries and peak flown measures. The physician intervention focused cliniciancs' attention on patients' diary records and peak flow measures, and encouraged physicians to use stepped action plans. Patients were also tested for allergic sensitization and provided strategies to reduce contact with allergens and other asthma triggers. The results showed significant improvements by intervention group families on measures of knowledge, health belief, self-efficacy, self-regulatory skill, and adherence; decreases in symptom persistence and activity restriction; and increased prescription of anti-inflammatory medication by the physicians of the intervention group families.

Enhancing medication adherence among inner-city children with asthma: results from pilot studies

Despite the availability of effective treatments that aid in controlling asthma symptoms, inner-city children with asthma have high rates of morbidity and are frequent users of emergency department services. The goal of these studies was to pilot test an intervention that used social learning strategies (e.g., goal-setting, monitoring, feedback, reinforcement, and enhanced self-efficacy) and targeted known barriers to individualize a family-based asthma action plan. Participants were 15 children with asthma, aged 7-12 years, who had been prescribed at least one daily inhaled steroid. The children and their mothers lived in inner-city Baltimore and all were African-American. Participants received up to five visits in their home by a nurse. Electronic monitors were installed on the children's MDI to provide immediate feedback on medication adherence to the families and validate medication use. At baseline, only 28.6% of the children were using their medications as prescribed. Within four weeks, the number of children who were using their medications appropriately doubled from 28.6% at baseline to 54.1% (90% increase; p = 0.004), while underutilization decreased from 51.2% to 25.4% (100% decrease; p = 0.02). The number of children with no medication use at all dropped from 28.3% at baseline to 15.1% by week 5 (87% decrease; p = 0.009). Thus, within four weeks, more than half the children were using their inhaled steroids appropriately. In addition, the rate of underutilization decreased and that of nonutilization was cut in half. Our initial data suggest that an individualized, home-based intervention can significantly enhance adherence to the daily use of inhaled steroids in inner-city children with asthma. Nevertheless, adherence to daily inhaled steroid therapy remains a significant problem in this group.

Contemporary approach to the emergency department management of pediatric asthma

Asthma continues to be an enormous health problem and economic burden in US society. EDs probably will continue to provide a substantial amount of care for those affected by the disease. Pediatric asthma patients frequently are encountered in EDs. Emergency physicians must remain current in their approach to providing expert care while the management of acute asthma exacerbations continues to evolve, older therapies are challenged and new therapies are developed, tested, and implemented.

Compliance bei chronisch kranken Kindern und Jugendlichen

Zusammenfassung. Compliance-Probleme bei Kindern/Jugendlichen mit Diabetes mellitus und Asthma bronchiale werden ausgeführt. Darüber hinaus wird der empirische Forschungsstand zu den Ursachen der Noncompliance dargestellt. Es wird verdeutlicht, wie der Krankheitsverlauf, die Behandlungserfordernisse, Patientenmerkmale und Faktoren des sozialen Umfelds die Compliance beeinflussen. Hierbei wird diskutiert, wie Noncompliance entsteht und welche Faktoren sie aufrechterhalten; zudem wird darauf eingegangen, wie die Compliance langfristig optimiert werden kann.

The relationship between prescribed and delivered doses of inhaled corticosteroids in adult asthmatics

A model was developed to estimate the impact of adherence and inhalation technique over time on delivered doses of inhaled corticosteroids (ICS) for asthmatics using metered-dose inhalers (MDIs) and dry powder inhalers (DPIs). Factors affecting inhalation technique include ongoing training, inhalation device, spacer use (with MDIs), and natural ability. Model parameters were derived from a literature review or were estimated from clinical experience. Analyses demonstrated that most patients receive a fraction of prescribed ICS doses over time. The model may be used to better understand the impact of increasing ICS dosages and to estimate the likelihood of patients being underdosed.

Patient self-management of acute asthma: adherence to national guidelines a decade later

BACKGROUND AND OBJECTIVES

Children in the emergency department (ED) with acute asthma were enrolled to assess the impact of asthma on their activities of daily living and evaluate their access to care and preventive strategies, determine the proportion who adhered to the National Heart, Lung, and Blood Institute (NHLBI) guidelines for proper steps to take at home during an acute asthma exacerbation, and compare adherence rates for those with persistent and mild intermittent asthma.

DESIGN AND METHODS

Children 2 to 18 years old who presented to the Children's Hospital of Philadelphia's ED with acute asthma exacerbations were enrolled prospectively. Parents and patients completed the 108-item Asthma Exacerbation Response Questionnaire with a focus on determining the home management steps they took both at the onset of the asthma exacerbation and just before coming to the ED.

RESULTS

Among the 433 children studied, 76% had at least 1 doctor visit, 75% had at least 1 ED visit, and 43% had at least 1 hospitalization for asthma in the preceding 12 months. Overall, 64% had persistent asthma by NHLBI criteria, yet just 4% were cared for by an allergist or pulmonologist, 38% took daily anti-inflammatory therapy, and 18% received a daily inhaled corticosteroid. Also, 48% did not use a holding chamber with their metered-dose inhalers, and 66% did not use their peak flow meters. Regarding exacerbation response, 71% did not have a written action plan, and 89% did not maintain a symptom diary. Both at the onset of wheezing and just before coming to the ED, administration of a beta2-agonist was the only step that the majority of children performed. One-third or fewer followed the other steps recommended by the NHLBI, including using a peak flow meter, beginning oral corticosteroids, calling or going to see the doctor, or going to the ED. Children with persistent asthma were not more adherent to the guidelines than those with mild intermittent disease.

CONCLUSIONS

Asthma has a significant adverse effect on the lives of these children. The NHLBI guidelines, first published a decade ago, were designed to reduce asthma's increasing morbidity and mortality, but this study uncovered a high rate of nonadherence with many aspects of the guidelines, including preventive strategies and home management of an exacerbation.

Medication use and health care contacts among symptomatic children with asthma

OBJECTIVE

Asthma morbidity and mortality continue to increase despite the availability of improved therapies. Little is known about the degree to which children with asthma use medications and health care services during symptomatic periods. This study documents prospectively the use of medications and health care contacts among children with active asthma symptoms.

METHODS

Children age 6--19 years from 11 primary care settings in upstate New York were eligible for this study if they had 3 or more asthma-related medical visits during the prior year. We collected extensive information on asthma symptoms, medication use, and contacts with health care providers from biweekly phone interviews and daily diaries during a 3-month period. Symptoms were evaluated as the average number of symptomatic days per week. We tabulated the proportion of children using anti-inflammatory medications and having health care contacts according to the frequency of their symptoms during this 3-month period. Chi-square and regression analyses were used.

RESULTS

One hundred sixty-five children participated (67% White, 24% Black, 9% Other). Sixty-five percent of the children in this sample had an average of more than 2 symptomatic days per week or more than 2 symptomatic nights per month during the 3-month study period and thus had mild persistent to severe asthma. Among these children, 25% received prednisone, and 46% reported the use of an inhaled maintenance medication during the monitoring period. Ten percent of children in this sample experienced an average of 6 or more symptomatic days per week during the study period. Among these highly symptomatic children, only 19% received prednisone, and 56% used a maintenance medication. Further, the proportion of children having contact with a health care provider during this 3-month period was 50% or less, even among the children experiencing the most frequent asthma symptoms. There were no differences in the proportion of children with health care contacts, prednisone use, or maintenance anti-inflammatory use among different gender or race categories or with different insurance types or places of residence.

CONCLUSIONS

Even among children experiencing almost daily asthma symptoms, inadequate anti-inflammatory therapy is common, and few contacts with health care providers occur. These children are silently suffering at home and likely are experiencing preventable morbidity.

A randomized, controlled trial of a simple emergency department intervention to improve the rate of primary care follow-up for patients with acute asthma exacerbations

STUDY OBJECTIVE

We determined whether a simple emergency department intervention improves the likelihood of primary care provider (PCP) follow-up after ED discharge for an acute asthma exacerbation.

METHODS

This randomized, controlled clinical trial was conducted in an urban university-based ED. Participants were patients with asthma between the ages of 16 and 45 years who were treated and discharged from the ED. The study intervention was usual care or an intervention that consisted of a free 5-day course of prednisone, vouchers for transportation to and from their PCP, and a 48-hour telephone reminder to make an appointment with their PCP. The main outcome was whether the patient received follow-up care as determined by PCP contact at 4 weeks.

RESULTS

One hundred ninety-two patients with asthma were enrolled over 8 months; 178 (93%) had complete follow-up. The intervention and control groups were similar with regard to age, sex, ethnicity, or years of education. The 2 groups were also comparable with respect to multiple measures of baseline access/barriers to care and severity of ED exacerbation. Patients receiving the intervention were significantly more likely to follow up with their PCP than control patients (relative risk 1.6; 95% confidence interval [CI] 1.1, 2.4). When adjusted for other factors influencing PCP follow-up care (ethnicity, prior PCP relationship, insurance status, regular car access), intervention patients were more likely to follow up with their PCP (odds ratio 3.1; 95% CI 1.5, 6.3).

CONCLUSION

Providing medication, transportation vouchers, and a telephone reminder to make an appointment increased the likelihood that discharged patients with asthma obtained PCP follow-up.
