    ABSTRACT

    Despite significant progress in asthma treatment, morbidity and mortality rates for childrenwith asthma have increased over the past decade. Poverty has been associated with an increased prevalence of asthma, level of severity, and increased hospitalizations due to asthma.Educational asthma self-management programs have been shown to reduce school absenteeism and symptoms, change health care utilization, and improve self management skills.However, most studies have included hospital-based or nondisadvantaged children. This paper reviews five unique community-based asthma management programs targeting inner-citydisadvantaged children. The asthma intervention studies were selected for review based on:(1) community involvement in subject recruitment or administration of the intervention; (2)basic asthma self-management education included as part of intervention; and (3) focusing oninner-city disadvantaged children and families.

    Similar findings across the five community-based programs included the need for educatinghealth professionals regarding asthma management, increased attention to the home environment, and targeting asthma education programs to undertreated groups who lack adequateaccess to care. Use of community settings, such as public schools, churches or community-based clinics, are optimal sites for delivering community-based asthma management programs. Linkages and partnerships between health professionals and community/local government organizations or parent groups can facilitate solving the housing, social, and medicalaccess problems of many inner-city families detected by the studies.

    African-American and impoverished children.'14' Poverty has been associated with an increased prevalence ofasthma,'4' level of severity,' 16-7' and hospitalizations due to asthma.'8' Not only are children in low-incomefamilies more likely to experience many illnesses, particularly chronic illnesses,'9' but they are also less likelyto receive adequate medical care.'10' Additional explanations for the increase in asthma morbidity and mortality in African-American children include increased exposure to environmental allergens and irritants (e.g.,passive cigarette smoke, cockroaches), lack of regular asthma care, inconsistent or nonexistent education regarding appropriate asthma medication use, and inadequate social resources.'11-13'

    Several educational self-management programs have demonstrated benefits in either reduced school absenteeism and symptoms reports, change in health service utilization, and improved self-management skills.'14-16'However, the majority of these intervention programs have included biased samples (e.g., volunteer or clinic-based subjects with few inner-city populations) and were clinic- or hospital-based rather than implemented directly in the community."7' Major elements shared by effective community-based asthma management programs include optimal clinical care through individualized medication plans, emphasis on parent and patienteducation, and attempts to reduce barriers to patient adherence.'18' The purpose of this paper is to review fiveunique community-based asthma management programs and propose recommendations for future programdevelopment and implementation.

    REVffiW OF FrVE COMMUNITY-BASED ASTHMA INTERVENTIONS

    Five community-based asthma intervention studies were selected for review based on the following criteria:first, subject recruitment and/or administration of the intervention was conducted exclusively in the community and community sites included public schools, community health clinics, or in the childrens' homes; second, all studies included basic asthma self-management education for parents and children; third, all studies focused on inner-city disadvantaged children and families.

    Case management and quality assurance programCase management and quality assurance techniques were utilized as an intervention for improving asthma

    care of Medicaid-eligible, inner-city children in Baltimore, Maryland.'18' Eighty-eight preschool children, whohad two or more emergency room visits for asthma within a three-month period, were targeted to receive theintervention. This program had three major components: assessment of the care of individual patients withfeedback to their primary care providers (PCPs), periodic contact with the parents by a nurse, and provision ofasthma education materials to parents.

    Specifically, telephone interviews with parents were conducted by the nurse to assess knowledge of homeasthma care and the type of care prescribed by the child's physician. Twenty-four hour telephone consultationfor asthma by the nurse or physician backup was available to the families. Each child's asthma managementplan was reviewed by a physician with the nurse to identify aspects of the patient's medical care that could beimproved. These included drug regimens, specific parent educational goals, and the need for allergy consultation. The patient's PCP was then contacted by the nurse and offered medical care suggestions for treatment ofthe child's asthma. No physician refused permission for a patient to participate. Bimonthly telephone callswere made to the parents in order to assess medication and educational needs. After any acute care visit to theemergency room, a telephone call was made to the parents, inquiring about the child's status and parents' understanding of the treatment plan. Written asthma education materials were also sent to the parents on a routinebasis.

    Outcome measures were evaluated and compared during two periods, including a three-month preinterven-tion and a three-month postintervention time period. From the first to the second period, acute care visits decreased by 50% suggesting that the intervention had some effect on acute care utilization. The authors conclude that use of case management and quality assurance techniques improved asthma management skills forall involved with the care of a child with asthma (e.g., the child, parent, physician, pharmacist, and teacher) asutilized in this program.

  • COMMUNITY-BASED ASTHMA INTERVENTIONS

    Community-based educational asthma programThis self-management educational intervention, implemented in public schools in Villawood, Sydney,

    Australia, was targeted to children with asthma and their parents, doctors, pharmacists, school teachers, andcommunity nurses.'17' Initially, 132 children were recruited from economically disadvantaged communities(intervention group, 72; control group, 60) who had: (1) a doctor's diagnosis of asthma; (2) a current asthmamedicine requirement; and (3) current bronchial hyperresponsiveness and recent symptoms. Each child assigned to the intervention group received two educational sessions at school with their parents present during aone-month period. An overview of a management plan was given to each family and their physician. Each family was asked to consult with their doctor to discuss the plan. All physicians who cared for children in the intervention group and all local pharmacists were invited to attend workshops that presented a well-used and respected asthma management plan.'19' All community health nurses from local health centers and all schoolteachers from the community received an asthma educational program conducted in their workplaces. If anyfamily member, doctor, or pharmacist did not attend the educational sessions, they were subsequently mailedasthma educational materials.

    Attendance rates for the educational sessions varied by group. All teacher and community health nurses attended the sessions as compared to very few pharmacists (21 %) and doctors (20%). Improvement in lung function in the children receiving the intervention was detected at the six month follow-up. In the interventiongroup, FEVj (forced expiratory volume in 1 second) was significantly improved from baseline (mean = 1.78L) as compared to the six-month follow-up (mean = 2.13 L; < 0.001). Unscheduled doctor or emergencyroom visits were also significantly reduced between the six-month follow-up and baseline (baseline mean =2.68, six month mean = 1.5\;p< 0.01).

    viding parental participation was the goal of this study in New York City.'20' Twelve public elementary schoolsfrom two New York community school districts agreed to enroll children with asthma, based on parental reports of at least three episodes of asthma in the past year. Each school was paired according to ethnic composition and size and then randomly selected to receive the education program or serve as a control school. A totalof 239 low-income children (experimental, 134; control group, 105) participated in the one-year follow-upstudy. Parents did not attend the educ
