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

Are primary care and continuity of care associated with asthma-related acute outcomes amongst children? A retrospective population-based study

BACKGROUND

Having a primary care provider and a continuous relationship may be important for asthma outcomes. In this study, we sought to determine the association between 1) having a usual provider of primary care (UPC) and asthma-related emergency department (ED) visits and hospitalization in Québec children with asthma and 2) UPC continuity of care and asthma outcomes.

METHODS

Population-based retrospective cohort study using Québec provincial health administrative data, including children 2-16 years old with asthma (N = 39, 341). Exposures and outcomes were measured from 2010-2011 and 2012-2013, respectively. Primary exposure was UPC stratified by the main primary care models in Quebec (team-based Family Medicine Groups, family physicians not in Family Medicine Groups, pediatricians, or no assigned UPC). For those with an assigned UPC the secondary exposure was continuity of care, measured by the UPC Index (high, medium, low). Four multivariate logistic regression models examined associations between exposures and outcomes (ED visits and hospitalizations).

RESULTS

Overall, 17.4% of children had no assigned UPC. Compared to no assigned UPC, having a UPC was associated with decreased asthma-related ED visits (pediatrician Odds Ratio (OR): 0.80, 95% Confidence Interval (CI) [0.73, 0.88]; Family Medicine Groups OR: 0.84, 95% CI [0.75,0.93]; non-Family Medicine Groups OR: 0.92, 95% CI [0.83, 1.02]) and hospital admissions (pediatrician OR: 0.66, 95% CI [0.58, 0.75]; Family Medicine Groups OR: 0.82, 95% CI [0.72, 0.93]; non-Family Medicine Groups OR: 0.76, 95% CI [0.67, 0.87]). Children followed by a pediatrician were more likely to have high continuity of care. Continuity of care was not significantly associated with asthma-related ED visits. Compared to low continuity, medium and high continuity of care decreased asthma-related hospital admissions, but none of these associations were significant.

CONCLUSION

Having a UPC was associated with reduced asthma-related ED visits and hospital admissions. However, continuity of care was not significantly associated with outcomes. The current study provides ongoing evidence for the importance of primary care in children with asthma.

Parents' self-reported experiences and information needs related to acute pediatric asthma exacerbations: A mixed studies systematic review

Objective

To systematically review the scientific literature examining parents' experiences and information needs for the management of their child's asthma exacerbations.

Methods

We searched five databases for quantitative and qualitative studies in Canada and the United States from 2002 onwards. A convergent integrated approach and the Mixed Method Appraisal Tool were used to analyze and appraise the evidence, respectively.

Results

We included 84 studies (27 quantitative, 54 qualitative, 3 mixed methods). Some parents lacked confidence in recognizing or managing exacerbations. A few parents were uncertain when and where to seek medical help. The main barrier to accessing care was cost. Impacts on parents included poor sleep, distress, and lifestyle disruptions. Parents felt they lacked information and wanted education on treatments and how to recognize and manage exacerbations via education sessions, written materials, community outreach and online resources.

Conclusion

Improved education for parents may help reduce parents' stress, asthma-related morbidities for children and use of urgent health services.

Innovation

The development of tailored interventions and knowledge translation strategies with input from target audiences (e.g. parents, health care providers) is necessary to meet their information needs and support adherence to clinical recommendations.

Factors that influence family and parental preferences and decision making for unscheduled paediatric healthcare - systematic review

INTRODUCTION

Health systems offer access to unscheduled care through numerous routes; however, it is typically provided by general practitioners (GPs), by emergency medicine doctors in in emergency departments (EDs) and by GPs in out-of-hours GP services such as practitioner cooperatives. Unscheduled healthcare constitutes a substantial portion of healthcare delivery. A systematic review was conducted to establish the factors that influence parents' decision making when seeking unscheduled healthcare for their children. The systematic review question was "What are the factors that influence the decision making of parents and families seeking unscheduled paediatric healthcare?"

METHOD

Five databases (CINAHL, PubMed, SCOPUS, PsycInfo, EconLit) and four grey literature databases (Proquest, Lenus, OpenGrey, Google Scholar) were searched. The titles and abstracts of 3746 articles were screened and full-text screening was performed on 177 of these articles. Fifty-six papers were selected for inclusion in the review. Data relating to different types of unscheduled health services (namely primary care, the emergency department and out-of-hours services) were extracted from these articles. A narrative approach was used to synthesise the extracted data.

RESULTS

Several factors were identified as influencing parental preferences and decision making when seeking unscheduled healthcare for their children. A number of the included studies identified pre-disposing factors such as race, ethnicity and socioeconomic status (SES) as impacting the healthcare-seeking behaviour of parents. Unscheduled healthcare use was often initiated by the parent's perception that the child's condition was urgent and their need for reassurance. The choice of unscheduled service was influenced by a myriad of factors such as: waiting times, availability of GP appointments, location of the ED, and the relationship that the parent or caregiver had with their GP.

CONCLUSION

Policy and planning initiatives do not always reflect how patients negotiate the health system as a single entity with numerous entry points. Altering patients' behaviour through public health initiatives that seek to improve, for instance, health literacy or reducing emergency hospital admissions through preventative primary care requires an understanding of the relative importance of factors that influence behaviour and decision making, and the interactions between these factors.

Visto, Pero No Escuchado: A Qualitative Arm of a Mixed-Methods Study of Puerto Rican Children With Asthma

INTRODUCTION

Communication among health care providers, caregivers, and children with asthma is challenging and sometimes may exclude the child. This may result in delay in recognizing and responding appropriately to asthma symptoms. The purpose was to conduct focus groups among Puerto Rican children with asthma on communication with their health care provider about their asthma symptoms.

METHOD

The qualitative arm (focus groups) of a mixed-method explanatory sequential study that was used to view communication with their health care provider through the lens of a group of Puerto Rican children. The sample included Puerto Rican children ages 8 to 12 years with asthma (N = 23). The goal was to develop a child illness representation questionnaire.

RESULTS

The perspective of children with asthma provided enriched information to influence the development of instrument subscale on communication. The children were often not heard during a clinical visit. Most of the children express fear of their health care provider.

CONCLUSIONS

Although this was a small sample, there were indications that children would like to opportunity to tell the story about their experience with having asthma. Further research will lead to the next step toward developing and computing a reliable measure that includes the child in a discussion during a clinical visit.

Children with Asthma and Communication with Healthcare Provider: Instrument Development

PURPOSE

Communication among healthcare providers, caregivers and children with asthma is challenging and sometimes may exclude the child. This may result in delay in recognizing and responding appropriately to asthma symptoms. The purpose was to test an instrument's subscale for content validity related to communication with the healthcare provider by examining age appropriateness, readability and clarity for children with asthma.

DESIGN AND METHODS

This was a mixed method explanatory sequential design to examine age appropriateness, readability and clarity for a 15-item subscale of an instrument for children. The qualitative arm (focus groups) was used to enrich the questionnaire. The sample included children ages 8 to 12 with asthma (N = 25).

RESULTS

The perspective of children with asthma provided enriched information to influence the development of instrument subscale on communication.

CONCLUSIONS

The subscale revealed internal consistency with Cronbach Alpha 0.85. One of the children reported that using the term "provider" was clearer as oppose to healthcare provider. Children participating in the study found readable and clear. A readability analysis revealed the items were readable at a 6th grade level.

PRACTICE IMPLICATION

Although the instrument is designed for primary care providers (physicians, nurse practitioners, physician assistants), the information gained from this pilot increases understanding about including the child in a triadic discussion. Further research will lead to next step toward computing reliability of the full measure and a factor analysis.

Experiences, Functioning and Needs of Low-Income African American Mothers of Children With Asthma

The purpose of this proposed study was to explore experiences, needs and functioning of low-income, African American caregivers of children with asthma in order to better understand symptom management.

METHOD

A qualitative, descriptive design was used. A purposive sampling technique was used to screen 32 caregivers of children with asthma, and 15 caregivers agreed to participate.

RESULTS

Three main themes were identified: managing the symptoms; cultural beliefs and values; and culturally competent health care provider.

CONCLUSION

For the caregivers culture disparity is not just about access to health services but instead the healthcare providers' understanding of the complexity of symptoms management.

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

OBJECTIVE

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

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

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

Findings from a community-based asthma education fair for Latino caregivers

OBJECTIVE

To assess limited English proficiency (LEP) asthma caregiver quality of life (QoL), skills retention and healthcare utilization after an asthma education fair (AEF).

METHODS

A language concordant AEF was conducted at a Latino community center. LEP caregivers of children 1-12 years old and an established asthma diagnosis participated in three skill stations: (a) medication recognition and administration, (b) peak flow use (if child ≥ 5 years) and (c) action plan dissemination. Spacers, peak flow meters and individualized action plans were distributed. A validated, pediatric asthma caregiver quality of life questionnaire (PACQLQ-Spanish version) was administered. Baseline data was compared to follow-up interview data at three and six months after the AEF. Mean PACQLQ scores were analyzed with Wilcoxon signed-rank test and nominal paired data with McNemar's test.

RESULTS

We analyzed data from 18 caregivers able to speak English well (22%), not well (28%) or not at all (50%). After three months, improved caregiver QoL was experienced (51 vs. 72, p<0.01). No differences were observed in medication recognition, spacer and peak flow use or peak flow interpretation. After six months, mean school days missed due to asthma decreased (4.1 vs. 0.4, p<0.01). Mean clinic visits, emergency department visits and hospitalizations remained unchanged.

CONCLUSIONS

Implementation of a community-based AEF with action plan administration can be beneficial for LEP caregivers and their children. QoL improvements to emotional wellbeing and activity limitations were observed, and lower rates of school absenteeism were reported. Caregiver ability to accurately identify medications was not enhanced.

The association of health literacy, social support, self-efficacy and interpersonal interactions with health care providers in low-income Latina mothers

OBJECTIVE

We explored relationships between maternal health literacy (HL), communicative self-efficacy (SE), social support (SS) and maternal perception of interactions with health care providers (HCPs).

METHODS

Using a cross-sectional, correlational design, we assessed sociodemographic characteristics, maternal HL, social support, communicative self-efficacy, and interpersonal interactions with HCPs among 124 low-income Latina mothers of young children.

RESULTS

Informal SS significantly predicted maternal SE in interactions. SE predicted maternal perception of a HCP's ability to "elicit and respond to her concerns."

DISCUSSION

Interventions to improve maternal self-efficacy in interacting with HCPs among low health literate Latina mothers may positively impact pediatric health outcomes.

Ethnic differences in caregiver quality of life in pediatric asthma

OBJECTIVE

The aim of this study was to determine ethnic and site differences in quality of life (QOL) in a sample of Latino (Puerto Rican [PR] and Dominican) and non-Latino white caregivers of children with asthma in mainland US and Island PR. We also investigated ethnic and site differences in associations between caregiver QOL and indicators of asthma morbidity.

METHOD

Seven hundred and eighty-seven children with asthma (7-16 years of age) and their primary caregivers participated in the study. Primary caregivers completed a measure of QOL, child asthma control, and emergency department utilization, among other measures.

RESULTS

Ethnic and site differences were found on total QOL scores (ΔF(1,783) = 29.46, p < .001). Island PR caregivers reported worse QOL scores than Rhode Island (Rl) Latino and non-Latino white caregivers; Rl Latino caregivers reported significantly worse QOL scores than non-Latino white caregivers. In Rl Latino and Island PR children, worse caregiver QOL was associated with asthma that was not in control and with one or more emergency department visits.

CONCLUSION

Latino caregivers may be experiencing a greater level of burden related to their child's asthma than non-Latino white caregivers. Caregiver QOL in pediatric asthma may be a reflection of broader contextual stress that some Latino caregivers experience on a daily basis (e.g., cultural beliefs, acculturation). Future research should continue to investigate mechanisms that explain the burden associated with pediatric asthma in Latino families, as well as whether QOL assessments should consider the impact of everyday stressors on caregiver QOL in pediatric asthma.

Modeling asthma exacerbations through lung function in children

BACKGROUND

Formal economic evaluation using a model-based approach is playing an increasingly important role in health care decision making.

OBJECTIVE

To develop a model by using an objective measure of lung function-- prebronchodilator FEV(1) as a percent of predicted (FEV(1)% predicted)--as the primary independent factor to predict the frequency of adverse events related to the exacerbation of asthma on a population level.

METHODS

We developed a Markov simulation model of childhood asthma by using data from the Childhood Asthma Management Program. The primary outcomes were the result of asthma exacerbations defined as hospitalizations, emergency department (ED) visits, and the need for oral corticosteroid therapy. Predicted monthly frequencies for each acute event were based on negative binomial regression equations estimated from the placebo arm of the Childhood Asthma Management Program with covariates of age, prebronchodilator FEV(1)% predicted, time in study, prior hospitalizations, and prior nocturnal awakenings.

RESULTS

Simulated versus observed mean number of acute events were similar within the placebo and treatment groups. While the trial demonstrated treatment effects of 48% reduction in hospitalizations, 46% reduction in ED visits, and 44% reduction in the need for oral corticosteroid therapy at 48 months, the model simulated similar reductions of 49% in hospitalizations, 41% in ED visits, and 46% in the need for oral corticosteroid therapy.

CONCLUSIONS

Our findings suggest that longitudinal intervention effects may be modeled through FEV(1)% predicted to estimate hospitalizations, ED visits, and need for oral corticosteroid therapy in childhood asthma for planning and evaluation purposes.

Puerto Rican families' experiences of asthma and use of the emergency department for asthma care

Puerto Ricans have been found to have higher asthma prevalence rates than non-Hispanic whites, blacks, and all other Hispanic subgroups. They also have the highest rates of emergency department (ED) use for the management of their asthma. Using a hermeneutic phenomenological approach, the aim of this study was to describe the lived experience of Puerto Rican families caring for their child's asthma and using the ED for asthma care. Six themes were generated from in-depth interviews with 10 Puerto-Rican caregivers: (1) The Folklore of Asthma, (2) Culture and the Medicine Woman, (3) In Awe of Asthma, (4) Praying to God, (5) The Decision-Time to Go, and (6) The ED Environment. The findings emphasize the necessity of establishing and maintaining a therapeutic partnership between primary care providers and families of children with asthma. The results may be used as a foundation for understanding motivations for seeking asthma care in the ED.

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.

Well-child care in infancy and emergency department use by South Carolina Medicaid children birth to 6 years old

OBJECTIVES

This analysis tests the hypothesis that children enrolled in Medicaid with the recommended early and periodic screening, diagnosis and treatment (EPSDT) visits in the first 24 months utilize fewer emergency department (ED) services birth to 6 years old than children with fewer visits.

METHODS

Data represent all health encounters for a 3-year birth cohort of South Carolina children continuously enrolled in Medicaid from birth to 6 years old (n = 18,512). The association between receiving the American Academy of Pediatrics recommended EPSDT visits and other health service utilization is examined.

RESULTS

Children with the recommended EPSDT visits had a greater adjusted rate of sick-child visits with a primary care provider (rate ratio, 1.62; 95% CI 1.50- 1.76) and a lower adjusted rate of ED visits for ambulatory care-sensitive conditions (rate ratio, 0.88; 95% CI, 0.81-0.95).

CONCLUSION

Recommended EPSDT use in infancy may be associated with a shift in health care from the ED to the office setting by children enrolled in Medicaid in the first six years of life.

The impact of socioeconomic factors on asthma hospitalization rates by rural classification

Asthma hospitalization rates have increased in the past decade. Research has shown that there are multiple correlates for this increase but that driving causal factors may differ for asthma hospitalization rates in rural and non-rural settings. Here we examine the socioeconomic correlates to asthma hospitalization rates in Maine for both rural and non-rural populations to examine the similarity and differences in causal factors. Findings indicate a clear SES gradient relative to asthma hospitalization rates; as population measured SES decreased, asthma hospitalization rates increased. The associated causal factors were found to differ in rural and non-rural areas. In non-rural areas, the presence of insurance was associated with increases in the asthma hospitalization rates while in rural areas, income, occupation and the percentage of non-English language speaking persons were associated with lower asthma hospitalization rates. Public policy should focus on targeted prevention strategies at the community level, especially in rural areas where cultural competency and socioeconomic factors are increasingly important.

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

BACKGROUND

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

OBJECTIVE

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

The Child Asthma Link Line: a coalition-initiated, telephone-based, care coordination intervention for childhood asthma

BACKGROUND

Childhood asthma is a complex chronic disease that poses significant challenges regarding management, and there is evidence of disparities in care. Many medical, psychosocial, and health system factors contribute to recognized poor control of this most prevalent illness among children, with resultant excessive use of emergency departments and hospitalizations for care. Recent national guidelines emphasize the need for community-based initiatives to address these critical issues. To address health system fragmentation and impact asthma outcomes, the Philadelphia Allies Against Asthma coalition developed and implemented the Child Asthma Link Line, a telephone-based care coordination and system integration program, which has been in operation since 2001. This study evaluates the effectiveness of the Child Asthma Link Line integration model to improve asthma management by measuring utilization markers of morbidity.

METHODS

Medicaid Managed Care Organization claims data for 59 children who received the Link Line intervention in 2003 are compared to a matched sample of 236 children who did not receive the Link Line intervention. Children in the two study groups are ages 3 through 12 years and matched on 2003 emergency department visits, age, gender, and race/ethnicity. Primary outcome variables analyzed in this study are emergency department visits, hospitalizations, and office visit claims from the follow-up year (2004).

RESULTS

Link Line intervention children were significantly less likely to have follow-up hospitalizations than matched sample children (p = .02). Children enrolled in the Link Line were also more likely to attend outpatient office visits in the follow-up year (p = .045). In addition, Link Line children with multiple emergency department visits in 2003 were significantly less likely to have an emergency department visit in 2004 (p = .046).

CONCLUSION

This coalition-developed, telephone-based, system-level intervention had a significant impact on childhood asthma morbidity as measured by utilization endpoints of follow-up hospitalizations and emergency department visits. Telephone-based care coordination and service integration may be a viable and economic way to impact childhood asthma and other chronic diseases.

Asthma mitigation strategies: professional, charitable, and community coalitions

BACKGROUND

Asthma symptoms, severity, and mortality are known to be affected by personal, family, and neighborhood social factors. Many groups have become involved in asthma research, education, and activism in the past 20 years. This study explores the approaches to asthma taken by community-based organizations compared with those taken by other organizations that have a focus on asthma.

METHODS

Priorities in asthma research and intervention were assessed through interviews with representatives of urban community-based participatory research (CBPR) coalitions; interviews with staff from charities focused on asthma, allergy, or lung diseases; interviews with physicians and scientists studying and treating asthma; participation in community forums; and participant observation of urban asthma coalitions. Interviews and data analysis were conducted in 2008.

RESULTS

There are marked differences in priorities and approaches to asthma among experts in the field, organizations and coalitions at the national and local levels, and other stakeholders in asthma research and activism. CBPR coalitions are more likely than asthma-focused organizations to explore environmental and community-level structural factors that exacerbate asthma or complicate its management, while disease-focused organizations, especially physician specialty groups, place more emphasis on individual-level factors. CBPR coalitions have been particularly strong in producing the data needed to demonstrate that individual communities are affected by pollution hot spots or that local neighborhoods lack geographic access to affordable medical care, and in providing this data to improve local policy-making.

CONCLUSIONS

Because of its focus on structural rather than individual factors, CBPR has helped to broaden the debate on asthma beyond clinical care and education into social and environmental justice.

Childhood asthma: ED follow-up determinants

INTRODUCTION

This comparative correlational study investigated families who use the emergency department for childhood asthma to identify determinants of follow-up care. The primary hypothesis was: families who obtain follow-up care differ in predisposing, enabling, and need characteristics from families who do not obtain follow-up care.

METHOD

A convenience sample of 63 children presenting to the pediatric emergency department of a Central Florida hospital were enrolled. Logistic regression techniques were utilized to explicate the individual and combined effects of the variables that best predicted the outcome variable. The dichotomous dependent variable was follow-up care within 30 days of the ED visit.

RESULTS

Sixty-seven percent of the children did not follow up as directed. Mother's level of education was significantly associated with no follow-up (P = .0282). Odds of no follow-up were higher for children with more severe asthma (odds ratio [OR] 12.44) or older mothers (OR 2.14).

DISCUSSION

Follow-up is not occurring at desired levels. Although this study has clinical and research implications for health care providers, further research is needed to identify follow-up determinants and develop interventions to improve follow-up rates and asthma outcomes.

The experience of being an Asthma Amigo in a program to decrease asthma episodes in Hispanic children

Asthma is the most common chronic illness among Latino children in urban areas. It is especially problematic for schools serving low-income and minority populations. The purpose of this study was to describe the experience of being an Asthma Amigo, a community-based educator who delivered asthma education to a Hispanic community in a train-the-trainer educational model. Focus group process evaluation was used to assess participant experiences and program strengths and weaknesses. Findings suggested that being an Asthma Amigo helped in gaining entrée into the community and in spreading the message of asthma triggers and prevention.

One gets so afraid: Latino families and asthma management--an exploratory study

INTRODUCTION

This study explored Latino family experiences, issues, and needs in caring for a child with asthma as expressed by Latino parents of children with asthma.

METHODS

Eight families represented by 7 women and 2 men, primarily of Mexican descent, participated in the study. All families had at least one child enrolled in preschools in the East Los Angeles area. The study had an exploratory design and used ethnographic group and individual interview techniques to discover the parents' experiences in managing their child's asthma and the meaning asthma has for their families. All interviews were conducted in Spanish.

RESULTS

Several common themes emerged from the data: (a) fear, "I got scared"; (b) the acute care experience, "I was not told what to do, nothing"; (c) knowledge, "I did not know anything about asthma"; and (d) parent alternative strategies or strengths, "We want to do what is best. ... we need to be prepared."

DISCUSSION

Strength emerged from fear. The parents were resourceful and began developing alternative strategies to assist them in their care for their child with asthma. The findings emphasize the need for more opportunities for culturally sensitive asthma education and community health care resources such as mobile asthma treatment centers and promotora programs.

Achieving and maintaining asthma control in an urban pediatric disease management program: the Breathmobile Program

BACKGROUND

National guidelines suggest that, with appropriate care, most patients can control their asthma. The probabilities of children achieving and maintaining control with ongoing care are unknown.

OBJECTIVE

We sought to evaluate the degree to which children in a lower socioeconomic urban setting achieve and maintain control of asthma with regular participation in a disease management program that provides guideline-based care.

METHODS

Interdisciplinary teams of asthma specialists use mobile clinics to offer ongoing care at schools and county clinics. A guideline-derived construct of asthma control is recorded at each visit.

RESULTS

Two thousand one hundred eighty-five enrollees were eligible to evaluate the time to first achieve control, and 1591 patients were eligible to evaluate subsequent control maintenance. Depending on severity, 70% to 87% of patients with persistent asthma achieved control by visit 3, and 89% to 98% achieved control by visit 6. Subsequent control maintenance was highly variable. Thirty-nine percent of patients displayed well-controlled asthma (control at >90% of subsequent visits), whereas 13% displayed difficult-to-control asthma (<50% of subsequent visits). Patients from each baseline severity category were found in each group. Maintenance of control was influenced by physician-estimated compliance with the treatment plan, baseline severity, and the interval between clinic visits.

CONCLUSIONS

Many children can achieve asthma control with regular visit intervals and guideline-based care; however, long-term control can be highly variable among patients in all severity categories.

CLINICAL IMPLICATIONS

These findings highlight the need and feasibility for systematically tracking each patient's clinical response to individualize therapy and guide the use of population management strategies.

Improving quality of care and promoting health care system change: The role of community-based coalitions

As part of their community action plans, the Allies Against Asthma coalitions have developed efforts to improve quality of care and promote health care system change. All the coalitions have used an interdisciplinary collaborative approach to design these strategies and demonstrated a range of intervention approaches appropriate to their local context and circumstances. The coalitions' collective experience suggests that coalitions provide three key forces for quality improvement and change that may be lacking in the current fragmented U.S. health care system--motivation to change the status quo, integration across systems, and accountability for results. The collaborative and empowering processes that a coalition model encourages and the direct advocacy opportunity provided to the consumer appear to bring these forces into play.

The coalition process at work: Building care coordination models to control chronic disease

Asthma is a highly prevalent and frequently misunderstood chronic disease with significant morbidity. Integrating client services at the patient-centered level and using coalitions to build coordinated, linked systems to affect care may improve outcomes. All seven Allies Against Asthma coalitions identified inefficient, inconsistent, and/or fragmented care as issues for their communities. In response, the coalitions employed a collaborative process to identify and address problems related to system fragmentation and to improve coordination of care. Each coalition developed a variety of interventions related to its specific needs and assets, stakeholders, stage of coalition formation, and the dynamic structure of its community. Despite common barriers in forming alliances with busy providers and their staff, organizing administrative structures among interinstitutional cultures, enhancing patient and/or family involvement, interacting with multiple insurers, and contending with health system inertia, the coalitions demonstrated the ability to produce coordinated improvements to existing systems of care.

Disparities in the use of urgent health care services among asthmatic children

BACKGROUND

Urgent care composes one third of the total costs associated with asthma. Asthmatic children of African American and Latino backgrounds have higher rates of emergency department (ED) use and hospitalizations than white children, especially in urban settings.

OBJECTIVE

To evaluate the role of socioeconomic, disease-related, and access-to-care factors in utilization of the ED and inpatient services for urgent treatment of asthma.

METHODS

A parent-response questionnaire was systematically distributed in public elementary schools that serve children of different socioeconomic backgrounds in New York City.

RESULTS

The prevalence of current asthma was found to be 13.0% in 5- to 12-year-old children. Almost half of the current asthmatic patients had used urgent care in the ED or hospital in the previous 12 months. In univariate analysis, use of urgent care was strongly associated with race/ethnicity and income (P < .001). Adjusting for socioeconomic, disease-related, and access-to-care factors, including household income, symptom severity, type of health insurance, and usual source of asthma care, the racial/ethnic disparity persisted, with Latinos having 5 times the risk and African Americans having double the risk of using urgent care as whites.

CONCLUSIONS

There is a failure in asthma management in this urban population, demonstrated by the finding that almost half of all current asthmatic patients used urgent care. After controlling for different socioeconomic and disease-related factors, minority race/ethnicity, low household income, and frequent evening symptoms were found to be strong predictors of urgent care utilization. Insurance status, delaying care for any reason, and use of controller medications were found not to be associated with urgent care use.

Increased continuity of care associated with decreased hospital care and emergency department visits for patients with asthma

The objective of this study was to determine the association between continuity of care and emergency room visits/hospital care for patients with asthma. A population-based study was conducted using administrative healthcare datasets obtained from Alberta Health and Wellness, Alberta, Canada. The 4-year study period extended from April 1, 1996 to March 31, 2000, and took place at the Palliser Health Region in Alberta, Canada, which has a population of 88,000 people. A population-based sample of 2774 patients, diagnosed with asthma between ages 5 and 45 with two or more office visits for asthma and who lived in the Palliser Health Region for 2 consecutive years during the study period, was studied. The main outcome measure was the association of continuity of care with hospitalizations and emergency room visits for patients with asthma. Continuity of care was the proportion of total physician visits made to the most frequently visited physician. High continuity of care was associated with a decreased risk of an emergency visit (OR = 0.24: 95% CI 0.19-0.29), number of emergency visits (RR = 0.37; 95% CI 0.32-0.42), decreased risk of number of hospitalizations (RR = 0.69; 95% CI 0.54-0.89), and total days in hospital (average difference = 0.77; 95% CI 0.63-0.95), but not with ever hospitalized. High continuity of care was associated with a 60%-75% reduction in emergency room visits and an approximate 25% reduction in number of hospitalizations in patients with asthma. Interventions to improve continuity of care could have the potential to improve care and reduce cost.

Emergency department visits for asthma: the role of frequent symptoms and delay in care

BACKGROUND

Use of the emergency department (ED) for asthma care is a costly form of health care that is largely preventable. However, little is known about how to reduce the number of people using the ED for asthma care.

OBJECTIVE

To identify modifiable factors related to ED visits for asthma among a diverse nonelderly adult population.

METHODS

This study used cross-sectional data from the 2001 California Health Interview Survey. A total of 4,359 adult respondents ages 18 to 64 years who reported being diagnosed as having asthma and experiencing symptoms in the past year were included. Any ED visits due to asthma in the previous 12 months among all nonelderly respondents with asthma, with stratification by those with daily or weekly symptoms and with less frequent symptoms, were examined.

RESULTS

Adults with daily or weekly asthma symptoms, with fair or poor health status, and who delayed care for asthma because of cost or insurance issues were more likely to visit the ED for asthma. Stratification of the study population into those with daily or weekly symptoms and those with less frequent symptoms revealed that delay in care due to cost or insurance issues and fair or poor health status remained significant for both groups. Latinos and women were more likely to visit the ED in the severe asthma group, whereas Asian, African American, and uninsured adults were more likely to visit the ED in the group with less severe asthma.

CONCLUSIONS

Results suggest that to prevent ED visits for asthma, it is important to control asthma symptoms. However, it is equally if not more important to reduce delays in receiving asthma care.

An interdisciplinary intervention for undertreated pediatric asthma

STUDY OBJECTIVES

To examine the effectiveness of an interdisciplinary intervention for pediatric asthma.

DESIGN

Randomized, controlled study.

SETTING

Urban tertiary-referral pediatric hospital.

PARTICIPANTS

One hundred seventy-five patients with asthma lacking written treatment plans and presenting with asthma-related emergency department visits (two or more) and/or hospitalizations (one or more) in the past year were randomized to a comparison group receiving medical care alone (n = 86) or to an interdisciplinary intervention group receiving medical care, asthma education, and problem-solving therapy (n = 89)

INTERVENTION

All participants received written asthma management plans, peak flow meters, and spacer devices. The intervention group also received asthma education, an asthma risk profile assessment, brief problem-solving therapy, and access to a 24-h nurse advice line. The primary outcome measure was change in asthma symptoms, and secondary outcomes included health-care utilization and asthma-related quality of life.

RESULTS

Both groups demonstrated significant reductions in asthma symptoms and improvements in quality of life without any between-group differences identified over the course of follow-up. In contrast, the intervention group demonstrated less frequent health-care utilization than the comparison group, with 28% of the intervention group requiring emergency department or inpatient services for asthma compared to 41% of the comparison group (adjusted odds ratio, 1.92; 95% confidence interval, 1.00 to 3.69) over the 12-month follow-up period.

CONCLUSIONS

This study examined the effectiveness of an interdisciplinary intervention for undertreated asthma. The intervention did not result in improvements in asthma symptoms, but accomplished modest reductions in the utilization of acute medical care.

Improving asthma research in an inner-city Latino neighborhood with community health workers

This study tests the feasibility of a partnership between an academic medical center and community health workers to perform mutually beneficial research investigating asthma in an urban Latino neighborhood. Community heath workers participated in the study design, instrument development, implementation, and analysis. The 103 participants recruited by the community health workers were primarily Mexican with very low education and acculturation levels. After the 1-year enrollment period, the community health workers described the challenges of data collection and gave explanations for the access to care outcomes. This academic-community partnership showed that community health workers can be effective research partners.

Improved asthma care after enrollment in the State Children's Health Insurance Program in New York

BACKGROUND

Uninsured children with asthma are known to face barriers to asthma care, but little is known about the impact of health insurance on asthma care.

OBJECTIVES

We sought to assess the impact of New York's State Children's Health Insurance Program (SCHIP) on health care for children with asthma.

DESIGN

Parents of a stratified random sample of new enrollees in New York's SCHIP were interviewed by telephone shortly after enrollment (baseline, n = 2644 [74% of eligible children]) and 1 year later (follow-up, n = 2310 [87%]). Asthma was defined by parent report using questions based on National Heart, Lung, and Blood Institute criteria. A comparison group (n = 401) who enrolled in SCHIP 1 year later was interviewed as a test for secular trends.

MAIN OUTCOME MEASURES

Access (having a usual source of care [USC], unmet health needs, problems receiving acute asthma care), asthma-related medical visits, quality (continuity of care at the USC, problems receiving chronic asthma care, use of antiinflammatory medications), and asthma outcomes (change in asthma care or severity) were the main outcome measures used. Bivariate and multivariate analyses compared measures at baseline (year before SCHIP) versus follow-up (year during SCHIP).

RESULTS

Three-hundred eighty-three children (14%) had asthma at baseline, and 364 had asthma at follow-up (16%). No secular trends were detected between the baseline study group and the comparison group. After enrollment in SCHIP, improvements were noted in access: lacking a USC (decrease from 5% to 1%), unmet health needs (48% to 21%), and problems getting to the USC for asthma (13 to 4%). Children had fewer asthma-related attacks and medical visits after SCHIP (mean number of attacks: 9.5 to 3.8: mean number of asthma visits: 3.0 to 1.5; hospitalizations: 11% to 3%). Quality of asthma care improved for general measures (most/all visits to USC: 53% to 94%; mean rating of provider: 7.9 to 8.8 of 10) and asthma-specific measures (problems getting to the USC for asthma care when child was well: 13% to 1%). More than two thirds of the parents at follow-up reported that both quality of asthma care and asthma severity were "better or much better" than at baseline, generally because of insurance coverage or lower costs of medications and medical care.

CONCLUSIONS

Enrollment in New York's SCHIP was associated with improvements in access to asthma care, quality of asthma care, and asthma-specific outcomes. These findings suggest that health insurance improves the health of children with asthma.

The Breathmobile Program: structure, implementation, and evolution of a large-scale, urban, pediatric asthma disease management program

Despite more than a decade of education and research-oriented intervention programs, inner city children with asthma continue to engage in episodic "rescue" patterns of healthcare and experience a disproportionate level of morbidity. The aim of this study was to establish and evaluate a sustainable community-wide pediatric asthma disease management program designed to shift inner city children in Los Angeles from acute episodic care to regular preventive care in accordance with national standards. In 1995 the Southern California Chapter of the Asthma and Allergy Foundation of America (AAFA), the Los Angeles County Department of Health Services (LAC DHS), and the Los Angeles Unified School District (LAUSD) established an agreement to initiate and sustain the Breathmobile Program. This program includes automated case identification, mobile school-based clinics, and highly structured clinical encounters supported by an advanced information technology solution. Interdisciplinary teams of asthma care specialists provide regular and ongoing care to children at school and county clinic sites over a wide geographic area of urban Los Angeles. Each team operates in a specially equipped mobile clinic (Breathmobile), efficiently moving a structured healthcare process to school and county clinic sites with large numbers of children. Demographic, clinical, and participation data is tracked carefully in an electronic medical record system. Program operations, clinical oversight, and patient tracking are centralized at a care coordination center. Clinical operations and methods have been replicated in fixed specialty clinic sites at the Los Angeles County + University of Southern California Medical Center. Clinical and process measures are regularly evaluated to assure quality, plan iterative improvement, and support evidence-based care. Four Breathmobiles deliver ongoing care at more than 90 school sites. The program has engaged over five thousand patients and their families in a continuity care model that has demonstrated efficacy over usual episodic care. More than 90% of patients in all asthma severity categories achieved clinical control of asthma with significant reductions in inpatient (IP) and emergency department (ED) use. On February 14, 2002, the program became the first program in the United States to receive the award of disease-specific care certification by the Joint Commission on Accreditation of Healthcare Organizations (JCAHO). Proper design and resource allocation can sustain a school-based community-wide pediatric asthma disease management program and shift a population of inner city children from acute episodic care to routine preventive care in accordance with national standards. An evidence-based approach to evaluating and maintaining quality, coupled with stratified care delivery, can assure the efficient use of safety net healthcare resources.

Prevalence of probable mental disorders among pediatric asthma patients in an inner-city clinic

OBJECTIVE

To determine the screen-positive prevalence of anxiety disorders and depression among pediatric asthma patients in an inner-city asthma clinic and to investigate the association between probable diagnoses of anxiety disorders and depression and medical service use among inner-city pediatric asthma patients.

METHOD

In this pilot study, a consecutive sample of pediatric asthma patients aged 5-11 in the waiting room of an inner-city asthma clinic was screened for mental disorders using the DISC Predictive Scales (DPS), which produces probable DSM-IV diagnoses. In addition, data on health service use for asthma were collected. Statistical analyses were performed to examine the relationship between probable anxiety disorders and depression and health service use for asthma among pediatric asthma patients.

RESULTS

Approximately one in four (25.7%) pediatric asthma patients in an inner-city asthma clinic met criteria for a probable diagnosis of current anxiety disorders or depression (past 4-week prevalence). Specifically, childhood separation anxiety disorder was common among 8.1%, panic among 14.9%, generalized anxiety disorder among 4.1%, agoraphobia among 5.4%, and 2.7% had depression. Having more than one anxiety disorder or depression diagnosis was associated with higher levels of inpatient and outpatient medical services, compared with patients who were negative on screening for anxiety or depressive disorders, although differences failed to reach statistical significance.

CONCLUSIONS

These findings are the first to provide preliminary evidence suggesting that mental health problems are common among pediatric asthma patients in an inner-city clinic. The results also suggest that mental health problems in pediatric asthma patients may be associated with elevated levels of medical service use for asthma. Replication of this pilot study is needed with a larger sample, more precise diagnostic methodology, and a comparison group with chronic medical illness.

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.

Urban asthma and the neighbourhood environment in New York City

Asthma is now the leading cause of emergency room visits, hospitalizations, and missed school days in New York City's poorest neighbourhoods. While most research focuses on the influence of the indoor environment on asthma, this study examines the neighbourhood effects on childhood asthma, such as housing and ambient environmental hazards. Using Geographic Information Science (GI Science) we identify neighbourhoods with elevated concentrations of childhood asthma hospitalizations between 1997 and 2000 in US census tracts, analyze the sociodemographic, housing characteristics, and air pollution burdens from stationary, land use and mobile sources in these areas. The paper reveals the importance of distinguishing the specific and often different combinations of poor housing conditions, outdoor air pollution and noxious land uses that contribute to the high incidence of asthma in impoverished urban neighbourhoods.
