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

A Content Analysis of Emergency Department Discharge Instructions for Acute Pediatric Febrile Illnesses: The Current State and Opportunities for Improvement

Quality emergency department (ED) discharge communication is critical to understanding of disease progression, home management, and return instructions. Addressing social aspects of disease burden are important to improving satisfaction and healthcare utilization. The objective of this study was to understand the extent to which written ED discharge instructions address multifaceted aspects of disease to meet the comprehensive needs of families with common childhood illnesses. We analyzed a national sample of 28 written discharge instructions from pediatric EDs using thematic and inductive content analysis. Seven themes were identified. Nearly all discharge instructions devoted a majority of content to themes related to disease physiology. Other themes common to instructions were related to parental instructions for caring for the child and when to return for further care. Content on caregiver reassurance, returning to daily activities, improving well-being, and promoting community health were not a focus of discharge instructions. Inclusion of multifaceted discharge materials which address both medical and social aspects of disease may help improve family-centered emergency care and the quality of care transitions for common childhood illnesses.

Cluster Analysis of Acute Care Use Yields Insights for Tailored Pediatric Asthma Interventions

STUDY OBJECTIVE

We undertake this study to understand patterns of pediatric asthma-related acute care use to inform interventions aimed at reducing potentially avoidable hospitalizations.

METHODS

Hospital claims data from 3 Camden city facilities for 2010 to 2014 were used to perform cluster analysis classifying patients aged 0 to 17 years according to their asthma-related hospital use. Clusters were based on 2 variables: asthma-related ED visits and hospitalizations. Demographics and a number of sociobehavioral and use characteristics were compared across clusters.

RESULTS

Children who met the criteria (3,170) were included in the analysis. An examination of a scree plot showing the decline in within-cluster heterogeneity as the number of clusters increased confirmed that clusters of pediatric asthma patients according to hospital use exist in the data. Five clusters of patients with distinct asthma-related acute care use patterns were observed. Cluster 1 (62% of patients) showed the lowest rates of acute care use. These patients were least likely to have a mental health-related diagnosis, were less likely to have visited multiple facilities, and had no hospitalizations for asthma. Cluster 2 (19% of patients) had a low number of asthma ED visits and onetime hospitalization. Cluster 3 (11% of patients) had a high number of ED visits and low hospitalization rates, and the highest rates of multiple facility use. Cluster 4 (7% of patients) had moderate ED use for both asthma and other illnesses, and high rates of asthma hospitalizations; nearly one quarter received care at all facilities, and 1 in 10 had a mental health diagnosis. Cluster 5 (1% of patients) had extreme rates of acute care use.

CONCLUSION

Differences observed between groups across multiple sociobehavioral factors suggest these clusters may represent children who differ along multiple dimensions, in addition to patterns of service use, with implications for tailored interventions.

Factors associated with patient visits to the emergency department for asthma therapy in Pakistan

BACKGROUND

Acute asthma is a chronic condition affecting people of all ages around the world and hence, is one of the leading causes of emergency department (ED) visits and hospital admissions globally. Most of them are related to poor patient practices and a weak healthcare system. The aim of our study was to assess the reasons for the increased usage of the ED by asthmatic patients in Pakistan.

METHODS

A cross-sectional study was conducted on 600 asthmatic patients reporting to the ED of Civil Hospital Karachi over a 6-month period. The consenting patients were given a questionnaire to fill and the following data was collected: demographic information, duration of the disease, medications prescribed the, frequency of and reasons for outpatient clinic and ED visits for issues related to asthma.

RESULT

According to our results most of the participants visited the ED to obtain a nebulized bronchodilator (90 %) or oxygen (79.5 %). Moreover, 44.8 % of the people visited the ED to get treatment without any delay and 24.0 % considered that the severity of asthma does not allow the patient to wait for clinic visits. Strikingly, 92.8 % claimed that inhaled corticosteroid therapy treatment should be stopped when patients feel better. Irregular follow ups with clinics, low education about asthma and an education level higher than a Bachelors degree were the most important factors associated with three or more ED visits per year, p values = 0.0289, 0.0110 and 0.0150 respectively.

CONCLUSION

This study identifies several preventable risk factors responsible for recurrent visits to the ED by asthmatic patients in Pakistan.

The Impact of Parent's Health Literacy on Pediatric Asthma Outcomes

Background: Health literacy has been associated with health disparities in many disease outcomes, including children's asthma. Parents are responsible for most of children's healthcare. Therefore, parents' health literacy may impact children's health outcomes, including asthma control. This study sought to determine the association between parent health literacy and children's asthma control among a cohort of predominately minority urban children aged between 6 and 12 years. Methods: This cross-sectional study assessed children with asthma and their parents at a single outpatient visit. English-speaking parents and their children, aged between 6 and 12 years with physician-diagnosed asthma, were eligible for this study. Healthcare providers assessed asthma control and severity, and parents completed demographic, health literacy, asthma control, and asthma knowledge measures. Children completed a pulmonary function test as part of the Asthma Control Questionnaire (ACQ) scoring. Results: A total of 281 parent-child dyads provided data, with the majority of parents being mothers and African American, with a high school level education or less. Lower parent health literacy was associated with worse asthma control as rated both by the provider (p=0.007) and the ACQ (p=0.013), despite only moderate concordance between ratings (ρ=0.408, p<0.0001). Lower parent health literacy also was associated with less asthma knowledge, which was associated with worse asthma control. Conclusions: Higher parent health literacy was associated with more parent asthma knowledge and better child asthma control. Pediatric providers should consider tailoring education or treatment plans or utilizing universal precautions for low health literacy.

Patient demographic and health factors associated with frequent use of emergency medical services in a midsized city

OBJECTIVES

To optimize health care utilization, health outcomes, and costs, research is needed to improve an understanding of frequent users of emergency health services. Frequent use of emergency services is associated with high costs of health care and may be indicative of challenges accessing, or poor outcomes of, health care. Patient demographics and health factors related to frequent use of the emergency medical services (EMS) system of a midsized city were identified. Study findings will aid in the development of targeted interventions to improve population health.

METHODS

The authors reviewed 9-1-1 call dispatch data and Baltimore City Fire Department (BCFD) EMS records from 2008 through 2010. Frequent use was defined as six or more EMS incidents in the 23-month period. Analyses used census data to compare demographics of EMS users to their population distribution and examined differences in demographics and health problems of frequent EMS users compared to nonfrequent users.

RESULTS

Frequent EMS users (n = 1,969) had a range of six to 199 EMS incidents (mean = 11.2) during the observation period, and although they accounted for only 1.5% of EMS users, they were involved in 12.0% of incidents. Frequent users, compared to nonfrequent users and to the population, were more likely to be male, African American, and 45 years of age or older. Of frequent users, the modal age group was 45 to 54 years, accounting for 29.7% of frequent users, which represented twice this age group's population distribution. Furthermore, this age group had the greatest overrepresentation of males (63.0% of frequent users) and was the peak age group for incidents related to substance abuse (28.0% of frequent users' incidents in this age group). Frequent users, compared to nonfrequent users, had lower levels of incidents related to trauma (5.1% vs. 16.7%) and higher levels of medical incidents (94.8% vs. 82.9%). As proportions of EMS incidents among frequent versus nonfrequent users, respiratory, mental health, and seizure-related incidents were highest in the youngest age groups; substance abuse-related incidents were highest in those middle-aged (35 to 44 and 45 to 54 years). Of health problems, behavioral health (mental health or substance use) contributed most to frequent EMS use (23.4% of frequent users' incidents). Across all incidents, 65.8% of frequent users had indications of behavioral health problems, representing 6.6-fold higher odds than nonfrequent users (22.5%). Frequent compared to nonfrequent users also had higher levels of select chronic conditions (diabetes, 39.9% vs. 14.6%; asthma, 40.9% vs. 13.4%; and HIV, 9.1% vs. 2.4%), with unadjusted odds almost four to seven times higher.

CONCLUSIONS

The study findings revealed the major role of chronic somatic and behavioral health problems in frequent EMS use and that rates of frequent use were highest among those middle-aged, African American, and male. These results suggest the need for coordination of EMS with community-based, integrated medical and behavioral health services to improve access and use of preventive services, with implications for health outcomes and costs. This study demonstrates the value of EMS patient data in identifying at-risk populations and informing novel, targeted approaches to public health interventions.

Factors associated with disparities in emergency department use among Latino children with asthma

BACKGROUND

Significant disparities in emergency department (ED) rates exist for Latinos; however, few studies have investigated the factors that may account for these disparities.

OBJECTIVES

To examine individual/family and health system factors among Latino and non-Latino white (NLW) children with asthma to explain disparities in ED rates.

METHODS

The study was carried out in Puerto Rico (PR) and Rhode Island (RI) with the same design: a cross-sectional, observational approach with repeated measurements of selected variables.

RESULTS

The sample was composed of 804 children ages 7 to 15 years, with 405 from PR and 399 from RI. Latino children from both sites had significantly higher rates of ED use as compared with NLWs from RI. Regression analyses showed site, asthma control, parental reported severity of asthma and public insurance to be significantly associated with ED use.

CONCLUSION

Latino ethnicity and public insurance were among the most important factors related to frequent ED use. Revisions of the policies driving public insurance to assure better access to specialists, preventive education, and evidence-based treatment are needed. The results also suggest the need for the development of interventions in the ED that are geared toward educating families on how best to use emergency services.

Characteristics of successful asthma programs

OBJECTIVE

We identified characteristics of interventions associated with positive asthma outcomes to understand how programs can be improved.

METHODS

We identified asthma interventions from the peer-reviewed literature or through a nomination process for unpublished programs. Initially, we identified 532 interventions. Of those, 223 met our eligibility criteria (e.g., focus on asthma, completed an evaluation, and demonstrated at least one asthma-related health outcome) and provided information on program components and processes, administration, evaluation, and findings through telephone interviews, program documents, and published reports. We analyzed bivariate relationships between programmatic factors and outcomes using Chi-square statistics, Fisher's exact tests, and unconditional logistic regression. We confirmed findings for all programs by analyzing the subset with published results in peer-reviewed journals.

RESULTS

Our findings indicated that programs were more likely to report a positive impact on health outcomes if they (1) were community based, (2) engaged the participation of community-based organizations, (3) provided program components in a clinical setting, (4) provided asthma training to health-care providers, (5) collaborated with other organizations and institutions and with government agencies, (6) designed a program for a specific racial/ethnic group, (7) tailored content or delivery based on individual health or educational needs, and (8) conducted environmental assessments and tailored interventions based on these assessments.

CONCLUSIONS

Positive asthma outcomes were associated with specific program characteristics: being community centered, clinically connected, and continuously collaborative. Program developers and implementers who build these characteristics into their interventions will be more likely to realize desired asthma outcomes.

Can equal access to care eliminate racial disparities in pediatric asthma outcomes?

A survey was given to the parents of 80 children with asthma between the ages of 3 and 18 years at the Pediatric Pulmonology Clinics of three military treatment facilities to evaluate asthma management and outcomes for different racial groups. Results demonstrated that management practices for the three groups were similar and that there were no significant differences in emergency department visits, prescription of oral steroids, or in the number of hospitalizations across the three groups. These findings suggest that equal access to care may allow children of different racial backgrounds to receive similar asthma care and achieve similar outcomes.

Factors associated to recurrent visits to the emergency department for asthma exacerbations in children: implications for a health education programme

INTRODUCTION

Recurrent emergency department (ED) visits for asthma exacerbations produce anxiety as well as high costs to the health system and the family.

OBJECTIVE

To identify factors associated with recurrent ED visits for asthma exacerbations in children in Bogotá, Colombia.

METHODS

Data obtained from a survey of parents of 223 patients with asthma (mean +/- SD: 4.8+/-3.5 years of age) attending an asthma clinic were analysed. Demographic data and a broad asthma knowledge and attitudes questionnaire were completed by the parents.

RESULTS

Of the 223 asthmatic patients enrolled, 60 (26.9 %) had 3 or more visits to the ED for asthma in the last 6 months ("recurrent ED visits"). After controlling by age, educational level of the father, and severity of the disease; parents of children with "recurrent ED visits" were more prone to report that they attended ED because the asthma exacerbations were severe enough to go to the primary care physician (OR, 2.45; CI 95 %, 1.13-5.30; p=0.02); that asthma medications should be administered only when the children are symptomatic (OR, 3.26; CI 95 %, 1.45-7.36; p=0.004), and conversely they were less prone to have knowledge that asthma exacerbations can be avoided if medications are administered in the asymptomatic periods (OR, 0.31; CI 95 %, 0.14-0.68; p=0.003).

CONCLUSIONS

An educational programme intended to reduce the recurrent ED visits for asthma exacerbations should consider the inclusion of an explanation about the chronic nature of the disease and the importance of long-term therapy.

Factors associated with acute health care use in a national adult asthma management program

BACKGROUND

The use of acute health care resources for asthma is considerable. Disease severity is an established risk factor, but ethnicity and health care factors are less well studied.

OBJECTIVE

To investigate the independent associations of ethnicity and health care factors with acute resource use for asthma.

METHODS

Longitudinal data from a national adult asthma management program providing universal access to care were analyzed. Outcome measures were unscheduled physician visits with urgent nebulization, emergency department (ED) visits, and hospitalizations.

RESULTS

In multivariate analyses, markers of disease severity were found to be significantly associated with all acute resource use. After controlling for disease severity, ethnicity was associated with increased risk of all acute resource use; Indian (vs Chinese) ethnicity was associated with increased risk of unscheduled physician visits (hazard ratio [HR], 1.32; 95% confidence interval [CI], 1.03-1.70), ED visits (HR, 1.61; 95% CI, 1.12-2.32), and hospitalizations (HR, 1.49; 95% CI, 1.03-2.16). Malay ethnicity was associated with unscheduled physician visits (HR, 1.30; 95% CI, 1.01-1.68) and ED visits (HR, 1.55; 95% CI, 1.09-2.19). Default of follow-up appointments was associated with unscheduled physician visits (HR, 1.47; 95% CI, 1.08-2.00), ED visits (HR, 2.35; 95% CI, 1.59-3.45), and hospitalizations (HR, 1.74; 95% CI, 1.09-2.76). Poor inhaler technique was associated with ED visits (HR, 1.86; 95% CI, 1.05-3.30) and smoking with unscheduled physician visits (HR, 1.38; 95% CI, 1.09-1.76).

CONCLUSIONS

In addition to markers of asthma severity, ethnicity, smoking, discontinuity of care, and self-care behavior are risk factors for acute resource utilization and represent target groups and elements of asthma intervention for improving asthma outcomes.

Randomized trial of a comprehensive asthma education program after an emergency department visit

BACKGROUND

Patients with asthma who visit the emergency department (ED) may benefit from education that optimizes self-management and treatment.

OBJECTIVE

To conduct a randomized trial of asthma education (AE) after an ED visit.

METHODS

Patients who present with acute asthma and history consistent with moderate to severe persistent asthma or recent ED visits were stratified by age (adult, child) and randomly assigned to intervention or usual care during the ED visit. The intervention was conducted by trained asthma educators and included a facilitated office visit with the primary care physician followed by a home visit. Intention-to-treat analysis was conducted, with time to first asthma relapse (either ED or unscheduled urgent office visit) during the 6-month follow-up period used as the primary outcome.

RESULTS

Of the 239 patients analyzed, 46% were adults, 46% were male, 30% were African American, and 56% had moderate to severe persistent asthma. Follow-up information was obtained on 191 patients (80%) at 6 months; 23.1% of the intervention group vs 31.1% of the usual care group had an urgent asthma visit (hazard ratio [HR], 0.79; 95% confidence interval [CI], 0.48-1.29). Overall, 39% of the 117 patients assigned to the intervention group did not comply with any of the post-ED activities. Subgroup analysis suggested greater benefit among children (HR, 0.62; 95% CI, 0.33-1.19) than adults (HR, 1.08; 95% CI, 0.50-2.33).

CONCLUSIONS

Delivery of a comprehensive AE program after an ED visit was ineffective in adult patients; however, it may be effective in children. Further research on alternative AE delivery strategies appears warranted to reduce the burden of asthma visits to the ED.

Asthma coaching in the pediatric emergency department

OBJECTIVES

Coaching and monetary incentives have been used to modify medical behavior of individuals with several chronic diseases, including asthma. The authors performed a randomized, controlled trial of an intervention combining asthma coaching during an emergency department (ED) visit for asthma, and monetary incentive to improve follow-up with primary care providers (PCP).

METHODS

Subjects were parents of children 2-12 years of age, with Medicaid or no medical insurance, receiving treatment for asthma in the ED. The primary outcome was a verified PCP visit for asthma within two weeks of the index ED visit. All parents received 15 dollars for their time in the ED. Parents in the intervention group were told that they would receive an additional 15 dollars monetary incentive if a PCP visit was completed. The coach engaged in a dialogue with the parent during the ED visit, and discussed the importance and advantages of seeking follow-up care with the child's PCP. All parents received the usual discharge instructions, including advice to see the PCP within three days.

RESULTS

The authors enrolled 92 parents; outcome data were available for 86 (42 controls, 50 intervention). Demographic characteristics were similar in both groups. There was no significant difference in the proportion of patients who had follow-up PCP visits between the intervention (22.0%; 95% confidence interval [95% CI] = 11.5% to 36.0%) and control (23.8%; 95% CI = 12.0% to 39.4%) groups (p = 0.99).

CONCLUSIONS

An intervention combining asthma coaching during acute ED visits and a monetary incentive to return for a PCP visit does not appear to increase follow-up with the PCP.

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.

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.

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.

Short-term clinical outcomes of acute treatment of childhood asthma

PURPOSE OF REVIEW

Acute exacerbations of asthma are the leading cause of emergency department visits in the pediatric patient. The present review is focused on the identification of those factors that may contribute to improving the short-term outcome of children after discharge from an emergency department visit for acute asthma.

RECENT FINDINGS

Several recent studies have documented that children treated at the emergency department because of an asthma-related event present a high morbidity at 7 and 15 days after discharge, mainly associated with symptom persistence, need for rescue bronchodilator medication, and absenteeism from school or day nursery. A better control of the disease, particularly adequate outpatient follow-up and maintenance treatment with inhaled steroids, could improve short-term clinical outcomes.

SUMMARY

All efforts of emergency room management of children with asthma, identification of severity of the current exacerbation episode, and intensive treatment of the acute asthma attack have usually been directed at reducing the rates of hospitalization and the return for medical care. However, according to reported data on short-term morbidity, it is necessary to define therapeutic and follow-up strategies after treatment for acute asthma and emergency department discharge. Besides standard treatment for an acute asthma exacerbation in a pediatric emergency department, action plans should include a review of the maintenance treatment of asthma to improve underlying disease control and a strong recommendation for close follow-up by the primary care pediatrician.

Asthma economics: focusing on therapies that improve costly outcomes

PURPOSE OF REVIEW

In 1998, the economic burden of asthma was estimated to be 12.7 billion dollars. Subsequent research has focused on identifying important outcomes that reflect high resource utilization and finding therapies that improve these outcomes and decrease cost. Recent developments include an update to the National Heart, Lung, and Blood Institute (NHLBI) guidelines, new treatment strategies using combination therapy, and the development of a monoclonal antibody therapy for asthma.

RECENT FINDINGS

Two important costly outcomes are asthma-related hospitalizations and emergency department visits. Asthma-related hospitalizations started to decline in the 1990s, primarily in white Americans, but not in young African Americans. Many hospitalizations and emergency department visits are preventable, and costs were lowered by shifting management to the ambulatory care setting. Increased asthma severity and suboptimal compliance with NHLBI asthma care guidelines can contribute to the persistence of symptoms, which triggers behaviors that increase resource utilization.A recent economic analysis was one of the first well-controlled clinical trials to show that inhaled corticosteroids provide clinical benefit at modest costs. Combination therapy, particularly that containing an inhaled corticosteroid and long-acting bronchodilator in a single inhaler, potentially can reduce overall costs by improving compliance with inhaled corticosteroids. Nonpharmacologic therapies also have been shown to be cost-effective. However, a significant number of patients with asthma continue to have symptoms even while on recommended controller therapy. Omalizumab, a monoclonal antibody treatment that binds IgE, was released in the summer of 2003.

SUMMARY

Many costly asthma-related hospitalizations and emergency department visits are preventable, and chronic disease care can be shifted to the ambulatory setting. Increased asthma severity and noncompliance with NHLBI guidelines are associated with increased resource utilization. Combination therapies can assist in improving patient compliance, and omalizumab potentially offers a novel but expensive way to decrease symptoms and resource utilization.

Predictors of health care utilization of children with asthma in the community

The aim of this study was to assess the pattern of use of health care services among children with asthma symptoms within the community, and assess groups at increased risk of emergency department (ED) visits or hospital admissions (HA). Using International Study of Asthma and Allergies in Childhood phase II protocol, information about asthma management and utilization of health care services was collected by parental questionnaire in a community-based random sample of 5-7- and 9-11-year-old children (n = 11,094) in Dresden and Munich. Only 11.2% of children with current wheeze did not utilize any health care facility or consultation for their asthma symptoms in the 12 months prior to survey, while 86.2%, 12.3%, and 3.6% had at least one asthma related physician's consultation, ED visits, or HA, respectively. Predictors of ED visits and HA among current wheezers were: younger age, male gender, speech-limiting wheeze, level of exposure to environmental tobacco smoke. In addition, children of low socioeconomic status were more likely to have ED visits because of their asthma. Childhood asthma is a major public health problem in Germany leading to substantial morbidity and utilization of health care services. Exposure to tobacco smoke comes out as the major modifiable risk factor related to asthma morbidity in children.

Development of an asthma disease management program in a children's hospital

The incidence, morbidity, and mortality of asthma have been increasing at an alarming rate, making asthma the most common chronic illness of childhood. An asthma disease management program was developed to improve the care and management of patients with asthma--a comprehensive health care delivery model that was designed to improve the management of patients with asthma was designed and implemented. The goal of the program was to provide high-quality interventions for those children diagnosed with asthma. The asthma disease management program at Children's Mercy Hospital improved the care received, decreased costs, and improved the quality of life for those children with asthma.
