Reducing Emergency Department Visits and Hospitalizations in African American and Hispanic Patients with Asthma: A 15-Year Review

Minority populations in the United States continue to experience a disproportionate share of emergency department (ED) visits and hospitalizations due to asthma. This review examines programs that have attempted to reduce these acute care visits in African American and Hispanic patients. We performed a PubMed search of the English literature for studies published from March 1990 to March 2005, aimed at reducing ED visits and hospitalizations in patients with asthma. Decreased acute care visits in African American and Hispanic patients with asthma have been demonstrated in several studies over the past 15 years, including collaboration by physicians, nurses, and clinical pharmacists in achieving this goal. These studies have shown that reduced acute care visits are associated with optimal drug therapy per national guidelines, concurrent with patient education, environmental control, and objective monitoring of this inflammatory airway disease. Early intensive patient education was a key feature of these successful programs. Written action plans, including early use of oral corticosteroids at home, and rapport with patients are other key components of programs that have resulted in a decrease in ED visits and hospitalizations.

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.     

Asthma Management Practices at Home in Young Inner-City Children

Information on parental asthma management practices for young children is sparse. The objective of this article is to determine if specific caregiver asthma management practices for children were associated with children's asthma morbidity. Caregivers of 100 inner-city children diagnosed with persistent asthma and participating in an ongoing asthma intervention study were enrolled and interviewed to ascertain measures of asthma morbidity, medication use, health care use (acute and primary care), and asthma management practices. Overall, asthma morbidity was high with almost two thirds of caregivers reporting their child having one or more emergency department visits within the last 6 months and 63% receiving specialty care for their asthma. Appropriate medication use was reported predominantly as albuterol and inhaled steroids (78%). However, only 42% of caregivers reported administering asthma medicines when their child starts to cough and less than half (39%) reported having an asthma action plan. There were no significant differences by asthma severity level for any asthma management practice. In conclusion, caregivers lack knowledge regarding cough as an early asthma symptom. Caregivers should be encouraged to review asthma action plans with health care providers at each medical encounter.     

The Asthma Outreach Project: A Promising Approach to Comprehensive Asthma Management

We describe a pilot system of coordinated asthma care emphasizing home visits by a community-based lay worker collaborating with a pediatrician, pharmacist, and public health nurse. Study participants included 23 low-income children with moderate to severe asthma and their families at an inner-city pediatric clinic. This system was successfully implemented, and client satisfaction was extremely high. Utilization review showed a reduction in hospitalizations, emergency department visits, and unscheduled clinic visits, and an increase in follow-up clinic visits. This model of care may reduce unscheduled service use and deserves further study as an alternative for asthma management among similar patient populations.

The Emergency Department as an Asthma Surveillance Tool at the Community Level: A Decline in the Burden of Pediatric Asthma in Halifax,Canada

We report pediatric emergency department (PED) asthma visit and inpatient asthma (AS) admission data in our area over a 5-year period. AS visits decreased by 33.9%, AS admissions by 24.6%, both significant compared with the decline in elementary school enrollment. The decrease in asthma visits was due to a decrease in the number of asthmatic patients, not a decline in repeat visits, or use of alternate venues of care. Explanations include a decrease in the burden of disease or an improvement in ambulatory care, but not alternate treatment venues or improvement in acute (PED) care. Readily available, emergency department data are useful in the community surveillance of asthma.

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.

Success of a Comprehensive School-Based Asthma Intervention on Clinical Markers and Resource Utilization for Inner-City Children with Asthma in Chicago: The Mobile C.A.R.E. Foundation's Asthma Management Program

Children with asthma in low-income households in Chicago were participants in a school-based mobile van clinic, Mobile C.A.R.E. Our objective was to investigate whether long-term follow-up changed clinical markers and resource utilization. Children were evaluated by a pediatrician in a mobile allergy clinic and classified and treated based on National Asthma Education and Prevention Program (NAEPP) guidelines. Intervention consisted of assessment of allergic environment with avoidance recommendations, institution of appropriate controller therapy and inhaler technique, education on asthma and asthma management, and expectations for asthma control. Over 20,000 children were screened, 2041 were examined at least once, and 677 children had four follow-up visits. With follow-up, there was a decrease in hospitalizations and emergency room visits. Symptomatic markers (daytime and nighttime cough, wheezing, and dyspnea symptoms), frequency of rescue inhaler use, and a quality-of-life score improved from baseline. These findings suggest that ongoing school interventions may reduce resource utilization and improve clinical symptoms. Primary care physicians may be able to deliver specialized care to large numbers of inner-city children with asthma.     

Reducing Home Triggers for Asthma: The Latino Community Health Worker Approach

This study assessed the ability of a community health worker asthma intervention to change home asthma triggers. A total of 56 children and 47 adults with asthma were enrolled. Home trigger scores for the children averaged 2.8 at the initial home visit and then 2.3, 2.1, and 2.0 at 3, 6, and 12 months. Home trigger scores for the adults showed a similar trend. Every home visit was associated with a 0.32 reduction in home trigger score (p < 0.01) for children and a 0.41 reduction (p < 0.01) for adults. This intervention shows promise as a way to reduce asthma triggers in urban low-income Latino communities.     

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.     

Perceived Involvement in Condition Management among Inner-City Youth with Asthma and Their Primary Caregivers

This study examined patterns of agreement versus disagreement in family perceptions of caregiver and youth involvement in asthma management tasks and associations of these patterns with youth asthma outcomes. Fifty-six caregiver-child dyads completed questionnaires of family involvement in asthma management and asthma health outcomes (i.e., symptom days, health care utilization, and medication adherence). Discrepancies were documented for perceptions of both caregiver and youth involvement. Caregiver overestimation of youth involvement in asthma management was associated with greater asthma severity and more asthma symptoms. Discrepancies in family perceptions of involvement pose salient challenges for effective clinical management and require clinical attention.     

Follow-Up of an Elementary School Intervention for Asthma Management: Do Gains Last Into Middle School?

Objective. Albuquerque Public Schools (APS), in collaboration with the Centers for Disease Control and Prevention, conducted an evaluation to examine whether students who were exposed to the APS asthma program in elementary school retained benefits into middle school. Methods. APS middle school students who participated in the APS asthma program in elementary school, including the Open Airways for Schools (OAS) education curriculum, responded to a follow-up questionnaire (N = 121) and participated in student focus groups (N = 40). Asthma management self-efficacy scores from the follow-up questionnaire were compared to scores obtained before and after the OAS education component. Additional items assessed students’ asthma symptoms, management skills, avoidance of asthma triggers, and school impact. Results. Although asthma management self-efficacy scores declined in middle school among students exposed to the asthma program in elementary school, they remained significantly higher than scores obtained during elementary school prior to the OAS intervention. Conclusion. The results indicate that although students benefited from the asthma program delivered in elementary school, they need booster sessions and continued school support in middle school.     

Acceptability and Feasibility of a Community Approach to Asthma Management: The Neighborhood Asthma Coalition (NAC)

Understanding of asthma and comanagement between patient and physician improves outcome. Feasibility of programs to achieve these goals in underserved settings is not documented. We used the Precede-Proceed model to document (a) community acceptance of a program to engage peer support of asthma management and care; (b) program revision to emphasize greater attention to availability of care and promotional events as channels for education; (c) engagement of intended audiences in planning and implementation; (d) participation of parents in program activities; and (e) peer-based education/support to reach parents, including socially isolated parents whose children experience heightened morbidity.

Community Health Workers and Environmental Interventions for Children with Asthma: A Systematic Review

Community health worker (CHW)–delivered, home-based environmental interventions for pediatric asthma were systematically reviewed. Seven PubMed/MEDLINE listed randomized controlled trials that encompassed the following intervention criteria were identified: (1) home-based; () delivered by a CHW; () delivered to families with children with asthma; and () addressed multiple environmental triggers for asthma. Details of research design, intervention type, and setting, interventionist, population served, and the evaluated outcomes were abstracted. Outcome assessment was broad and non-uniform. Categories included direct mediators of improved health outcomes, such as trigger-related knowledge, trigger reduction behaviors and allergen or exposure levels, and asthma-related health outcomes: change in lung function, medication use, asthma symptoms, activity limitations, and health care utilization. Indirect mediators of health outcomes, or psychosocial influences on health, were measured in few studies.

Overall, the studies consistently identified positive outcomes associated with CHW-delivered interventions, including decreased asthma symptoms, daytime activity limitations, and emergency and urgent care use. However, improvements in trigger reduction behaviors and allergen levels, hypothesized mediators of these outcomes, were inconsistent. Trigger reduction behaviors appeared to be tied to study-based resource provision. To better understand the mechanism through which CHW-led environmental interventions cause a change in asthma-related health outcomes, information on the theoretical concepts that mediate behavior change in trigger control (self-efficacy, social support) is needed. In addition, evaluating the influence of CHWs as clinic liaisons that enhance access to health professionals, complement clinic-based teaching, and improve appropriate use of asthma medications should be considered, alongside their effect on environmental management. A conceptual model identifying pathways for future investigation is presented.     

Asthma Knowledge and Asthma Management Behavior in Urban Elementary School Teachers

Background. Although schools are an important setting for asthma care in youth, teachers’ asthma knowledge and symptom management is poor. This study investigated the knowledge, prevention and management behaviors, and communication regarding asthma of teachers of low-income, ethnic minority students. It was hypothesized that relative to colleagues whose students did not have active asthma (i.e., did not have symptoms during the day), teachers of students with active asthma would have better asthma knowledge and that more would take asthma prevention steps and communicate with parents and school nurses. Methods. Drawing from 25 elementary schools in New York City, 320 pre-Kindergarten through 5th grade classroom teachers with at least one student with asthma completed measures assessing their asthma knowledge, steps taken to manage asthma, communication with the school nurse or parents, information they received about asthma, and whether or not they had at least one student in their class experience asthma symptoms. t test and chi-square were used to test hypotheses. Results. Asthma knowledge varied among teachers. Most could identify potential triggers, yet few knew that medication taken prior to exercise could prevent symptoms and that students with asthma need not avoid exercise. Communication between teachers and school nurses and between teachers and parents was lacking. Relative to colleagues whose students did not have active asthma, teachers whose students had active asthma had better asthma knowledge, more took steps to prevent students from having asthma symptoms, communicated with parents, and more initiated communication with the nurse. Conclusions. Teachers’ knowledge about asthma and asthma management is limited, especially among those whose students did not have active asthma. Teachers respond reactively to students who have symptoms in class by increasing prevention steps and communications with parents and the school nurse. A more proactive approach to managing asthma in schools is warranted.     

Management Preferences of Pediatricians in Moderate and Severe Acute Asthma

Objective. To assess and compare management preferences of physicians for moderate and severe acute asthma based on case scenarios and to determine the factors influencing their decisions.Methods. A questionnaire based on the Global Initiative on Asthma (GINA) guideline and comprising eight questions on management of acute asthma was delivered to participants of two national pediatric congresses. Management of moderate and severe acute asthma cases was evaluated by two clinical case scenarios for estimation of acute attack severity, initial treatment, treatment after 1h, and discharge recommendations. A uniform answer box comprising the possible choices was provided just below the questions, and respondents were requested to tick the answers they thought was appropriate. Results. Four-hundred and eighteen questionnaires were analyzed. All questions regarding moderate and severe acute asthma case scenarios were answered accurately by 15.8% and 17.0% of physicians, respectively. The initial treatment of moderate and severe cases was known by 100.0% and 78.2% of physicians, respectively. Knowledge of the appropriate plan for treatment after 1h was low both for moderate (45.0%) and severe attacks (35.4%). Discharge recommendations were adequate in 32.5% and 70.8% of physicians for moderate and severe attacks, respectively. Multiple logistic regression analysis revealed that working at a hospital with a continuing medical education program was the only significant predictor of a correct response to all questions regarding severe attacks (p = .04; 95%CI, 1.02–3.21). No predictors were found for information on moderate attacks. Conclusions. Pediatricians have difficulty in planning treatment after 1 hour both for moderate and severe asthma attacks. Postgraduate education programs that target physicians in hospitals without continuing medical education facilities may improve guideline adherence.
