Previous work has indicated a high rate of non-attendance at hospital based clinics among young, multiracial asthmatic patients of lower socioeconomic class. The efficacy of delivering asthma education from a community health centre established in a multiracial working class neighbourhood was evaluated.
                A prospective controlled study was performed in which asthmatic subjects aged between two and 55 years attending a hospital emergency room with acute asthma and living within a defined geographical area of high emergency room users were randomised to the usual follow up or the education centre plus usual follow up. Measurements were taken at entry into the study and again nine months later.
                At nine months patients randomised to the education centre had more preventive medications, more peak expiratory flow meters and better flow meter technique, more self-management plans, better knowledge of appropriate action to take when confronted with worsening asthma, less nocturnal awakening, and better self-reported asthma control than the control group. There was no difference between the study groups in measurements of compliance, hospital admission, days lost from school or work, or emergency room use.
                The main effects of education were on asthma knowledge and self-management skills, whilst improvements in asthma morbidity were small. Potential reasons for this include heterogeneous study population (in terms of baseline self-management skills, asthma severity, ethnicity and age), pragmatic study design, insensitivity of many of the measurements of morbidity, the modest effectiveness of a single time limited education programme, and inability to limit the effects of such a large community based study to the intervention group (there was a 67% reduction in asthma admissions during the study period from the geographical area targeted compared with a 22% reduction for the rest of Auckland). Despite significant medical advances, many ethnic and racial minority children who live in inner cities continue to experience disproportionately high levels of asthma morbidity and mortality compared with white children. As a result, a growing number of psychosocial asthma management interventions are being developed to address their needs; however, only a few of these interventions have incorporated cultural variables into their treatments and have had their efficacy evaluated.
                To examine the efficacy of the Multifamily Asthma Group Treatment (MFAGT), designed to enhance asthma management and reduce emergency department (ED) visits among African American and Hispanic families.
                Twenty-four African American and Hispanic families who have children with asthma were randomly assigned to either the MFAGT or the Standard Psychoeducational Asthma Intervention. Differences in the number of ED visits and the level of asthma management in both groups were compared 1 year before and 1 year after the intervention. In addition, these groups were contrasted to a control group that did not receive any psychoeducational intervention.
                The MFAGT was significantly (P = .04) more effective than the Standard Psychoeducational Asthma Intervention and the control in decreasing ED visits and increasing parental asthma knowledge.
                These preliminary results suggest that the MFAGT is efficacious in enhancing asthma management and in reducing ED visits in inner-city African American and Hispanic children from a lower socioeconomic background. Whether asthma morbidity in minority groups can be reduced by preventative health care measures delivered in the relevant ethnic dialects requires further evaluation. This study reports clinical outcomes and quality of life from a community based project investigating white European (W/E) and Indian subcontinent (ISC) ethnic groups with asthma living in deprived inner city areas of Birmingham, UK.
                Six hundred and eighty nine asthmatic subjects (345 W/E, 344 ISC) of mean (SD) age 34.5 (15) years (range 11-59) and mean forced expiratory volume in one second (FEV(1)) of 80% predicted were interviewed in English, Punjabi, Hindi, or Urdu. Subjects randomised to the active limb of a prospective, open, randomised, controlled, parallel group, 12 month follow up study underwent individually based asthma education and optimisation of drug therapy with four monthly follow up (active intervention). Control groups were seen only at the beginning and end of the study. Urgent or emergency interactions with primary and secondary health care (clinical outcomes) and both cross sectional and longitudinal data from an Asthma Quality of Life Questionnaire (AQLQ) were analysed.
                Clinical outcomes were available for 593 subjects. Fewer of the active intervention group consulted their GP (41.8% versus 57.8%, odds ratio (OR) 0.52 (95% CI 0.37 to 0.74)) or were prescribed antibiotics (34.9% versus 51.2%, OR 0.51 (95% CI 0.36 to 0.72)), but by ethnicity statistically significant changes occurred only in the W/E group with fewer also attending A&E departments and requiring urgent home visits. Active intervention reduced the number of hospital admissions (10 versus 30), GP consultations (341 versus 476), prescriptions of rescue oral steroids (92 versus 177), and antibiotics (220 versus 340), but again significant improvements by ethnicity only occurred in the active W/E group. AQLQ scores were negatively skewed to the higher values; regression analysis showed that lower values were associated with ISC ethnicity. Longitudinal changes (for 522 subjects) in the mean AQLQ scores were small but statistically significant for both ethnic groups, with scores improving in the active and worsening in the control groups.
                Active intervention only improved clinical outcomes in the W/E group. AQLQ scores, although lower in the ISC group, were improved by active intervention in both ethnic groups. This study was designed to answer three main questions: 1) Does asthma self-management education reduce asthma morbidity? 2) Are the two programmes "Living With Asthma" and "Open Airways" equally effective in doing so? 3) Is a shortened version of these programmes (4 weeks) as effective as the longer original programme (8 weeks)? Twelve Italian centres of paediatric bronchopneumology selected 312 children with asthma, who were stratified by disease severity, gender and age, and then randomly assigned to an Experimental group which received an educational programme or to a Comparison group, which did not. Of the 312 children selected, 209 (114 Experimental and 95 Comparison) completed the educational protocol and a 1 year follow-up. Data recorded during the last 2 months of follow-up, 10 months after the educational intervention, showed that the Experimental group required significantly fewer emergency treatments: this reduction was more evident in the more severe asthma cases. In the Experimental, but not in the Comparison group, patients with more severe asthma consumed more medications than patients with milder asthma "Open Airways" yielded, in some cases, better results than "Living with Asthma": but a type 2 error is possible. The standard and the shortened programmes proved equally effective. In conclusion, following education, regardless of receiving a short or long educational programme, asthma patients use emergency care services less and use medications more appropriately in comparison with standard care without education. This suggests that short educational programmes can be highly cost-effective in children with asthma. To assess the outcomes of an education intervention for childhood asthma conducted by Australian Indigenous health care workers (IHCWs).
                Randomised controlled trial in a primary health care setting on Thursday Island and Horn Island, and in Bamaga, Torres Strait region of northern Australia, April 2005 to March 2007.
                88 children, aged 1-17 years, with asthma diagnosed by a respiratory physician (intervention group, 35; control group, 53; 98% Indigenous children).
                Children were randomly allocated to: (i) three additional asthma education sessions with a trained IHCW, or (ii) no additional asthma education. Both groups were re-assessed at 12 months.
                Primary endpoint: number of unscheduled visits to hospital or a doctor caused by asthma exacerbation. Secondary outcomes: measures of quality of life (QoL) and functional severity index; asthma knowledge and understanding of asthma action plans (AAPs); and school days missed because of wheezing.
                The groups were comparable at baseline (except for asthma severity, which was adjusted for in the analysis). There were no significant differences in the primary outcome (number of unscheduled medical visits for asthma). School children in the intervention group missed fewer school days because of wheezing (100% < 7 days v 21% of those in the control group missed 7-14 days). Significantly more carers in the intervention group could answer questions about asthma medication, knew where their AAP was kept (84% v 56%), and were able to describe the plan (67% v 40%). In both the intervention and control groups (before-and-after comparison), there was a significantly reduced frequency of asthma exacerbations, as well as an improved QoL score and functional severity index, with no significant differences between the groups.
                A community-based asthma education program conducted by trained IHCWs improves some important asthma outcomes in Indigenous children with asthma.

                Cluster randomised controlled trial.
                44 general practices in two boroughs in east London.
                324 people aged 4-60 years admitted to or attending hospital or the general practitioner out of hours service with acute asthma; 164 (50%) were South Asian patients, 108 (34%) were white patients, and 52 (16%) were from other, largely African and Afro-Caribbean, ethnicities.
                Patient review in a nurse led clinic and liaison with general practitioners and practice nurses comprising educational outreach, promotion of guidelines for high risk asthma, and ongoing clinical support. Control practices received a visit promoting standard asthma guidelines; control patients were checked for inhaler technique.
                Percentage of participants receiving unscheduled care for acute asthma over one year and time to first unscheduled attendance.
                Primary outcome data were available for 319 of 324 (98%) participants. Intervention delayed time to first attendance with acute asthma (hazard ratio 0.73, 95% confidence interval 0.54 to 1.00; median 194 days for intervention and 126 days for control) and reduced the percentage of participants attending with acute asthma (58% (101/174) v 68% (99/145); odds ratio 0.62, 0.38 to 1.01). In analyses of prespecified subgroups the difference in effect on ethnic groups was not significant, but results were consistent with greater benefit for white patients than for South Asian patients or those from other ethnic groups.
                Asthma specialist nurses using a liaison model of care reduced unscheduled care for asthma in a deprived multiethnic health district. Ethnic groups may not benefit equally from specialist nurse intervention. Childhood asthma is common in Cape Town, a province of South Africa, but is underdiagnosed by general practitioners. Medications are often prescribed inappropriately, and care is episodic. The objective of this study is to assess the impact of educational outreach to general practitioners on asthma symptoms of children in their practice.
                This is a cluster randomised trial with general practices as the unit of intervention, randomisation, and analysis. The setting is Mitchells Plain (population 300,000), a dormitory town near Cape Town. Solo general practitioners, without nurse support, operate from storefront practices. Caregiver-reported symptom data were collected for 318 eligible children (2 to 17 years) with moderate to severe asthma, who were attending general practitioners in Mitchells Plain. One year post-intervention follow-up data were collected for 271 (85%) of these children in all 43 practices. Practices randomised to intervention (21) received two 30-minute educational outreach visits by a trained pharmacist who left materials describing key interventions to improve asthma care. Intervention and control practices received the national childhood asthma guideline. Asthma severity was measured in a parent-completed survey administered through schools using a symptom frequency and severity scale. We compared intervention and control group children on the change in score from pre-to one-year post-intervention.
                Symptom scores declined an additional 0.84 points in the intervention vs. control group (on a nine-point scale. p = 0.03). For every 12 children with asthma exposed to a doctor allocated to the intervention, one extra child will have substantially reduced symptoms.
                Educational outreach was accepted by general practitioners and was effective. It could be applied to other health care quality problems in this setting. The objective of the study was to assess the feasibility of implementing and evaluating a culturally appropriate in-patient asthma education program specifically targeted for African-Americans. A consecutive sample of 28 African-American patients ages 18-50 who were hospitalized for asthma were randomized to an intervention group, which received three one-on-one sessions on chronic asthma management, or a control group, which received the usual care. Data on symptom frequency, self-management behaviors, quality of life, depression, and health care resource use were collected at baseline and at 3 and 6 months. Although the time required to recruit our sample took longer than anticipated, 28 subjects agreed to be in the study (70% acceptance rate) and complete the baseline interview. We observed no statistically significant differences from baseline or changing trends in frequency of asthma symptoms, self-management behaviors, and health care resource use between the intervention and control groups at 3 and 6 months. However patients in the intervention group demonstrated a greater average increase in asthma-related quality of life and a greater average decrease in depression than the control group. Feasibility issues included shortened length of stay, which necessitated conducting all three self-management sessions together; multiple interruptions during the sessions, and retention issues at 3- and 6-month follow-ups. The lessons learned from this pilot study are invaluable in that they will enable us to make changes in our existing protocol to ensure the success of a larger clinical trial. Recent studies have shown that lack of continuing primary care for asthma is associated with increased levels of morbidity in low-income minority children. Although effective preventive therapy is available, many African-American and Latino children receive episodic treatment for asthma that does not follow current guidelines for care. To see if access, continuity, and quality of care could be improved in pediatric clinics serving low-income children in New York City, we trained staff in New York City Bureau of Child Health clinics to provide continuing, preventive care for asthma.
                We evaluated the impact of the intervention over a 2-year period in a controlled study of 22 clinics. Training for intervention clinic staff was based on National Asthma Education and Prevention Program guidelines for the diagnosis and management of asthma, and included screening to identify new cases and health education to improve family management. The intervention included strong administrative support by the Bureau of Child Health to promote staff behavior change. We hypothesized that after the intervention, clinics that received the intervention would, compared with control clinics, have increased numbers of children with asthma receiving continuing care in the clinics and increased staff use of new pharmacologic and educational treatment methods.
                In both the first and second follow-up years, the intervention clinics had greater positive changes than control clinics on measures of access, continuity, and quality of care. For second year follow-up data these include: for access, greater rate of new asthma patients (40/1000 vs 16/1000; P < .01); for continuity, greater percentage of asthma patients returning for treatment 2 years in a row (42% vs 12%; P < .001) and greater annual frequency of scheduled visits for asthma per patient (1.85 vs .88; P < .001); and for quality, greater percentage of patients receiving inhaled beta agonists (52% vs 15%; P < .001) and inhaled antiinflammatory drugs (25% vs 2%; P < .001), and greater percentages of parents who reported receiving patient education on 12 topics from Bureau of Child Health physicians (71% vs 58%; P < .01) and nurses (61% vs 44%; P < .05).
                We conclude that the intervention substantially increased the Bureau of Child Health staff's ability to identify children with asthma, involve them in continuing care, and provide them with state-of-the-art care for asthma.
Current limited data show that culture-specific programmes for adults and children from minority groups with asthma, are more effective than generic programmes in improving most (quality of life, asthma knowledge, asthma exacerbations, asthma control) but not all asthma outcomes. This evidence is limited by the small number of included studies and the lack of reported outcomes. Further trials are required to answer this question conclusively.
