Home‐based educational interventions for families of children with asthma

This version published: 2014; Review content assessed as up-to-date: January 14, 2011.

Plain language summary

Asthma is a common childhood illness causing wheezing, coughing and difficulty in breathing. Guidelines on the care of children with asthma recommend that children and families should receive education on how to manage their condition. The current review looked at 12 studies with a total of 2342 children comparing asthma education received at home with either usual care or a less intensive home‐based education programme. Eleven out of 12 trials were conducted in North America, within urban or suburban settings involving socioeconomically disadvantaged families. A table summarising some of the key components of the education programmes is presented in the review.

The included studies varied in the characteristics of children (e.g. age, severity of asthma), the education delivered and the way each outcome was reported. This made it difficult to compare the results and provide overall conclusions and we did not pool results for most of the outcomes. There was also diversity in the findings of the individual trials. We were able to combine the results of two studies reporting the average number of emergency department visits per child, which was not different at six months between the home education group and the group receiving the usual care. Only one trial contributed to our other primary outcome, exacerbations (flare‐ups) requiring a course of oral corticosteroids. Hospital admissions also demonstrated wide variation between trials with significant changes in some trials in both directions. Quality of life improved in both education and control groups over time.

Abstract

Background: While guidelines recommend that children with asthma should receive asthma education, it is not known if education delivered in the home is superior to usual care or the same education delivered elsewhere. The home setting allows educators to reach populations (such as the economically disadvantaged) that may experience barriers to care (such as lack of transportation) within a familiar environment.

Objectives: To perform a systematic review on educational interventions for asthma delivered in the home to children, caregivers or both, and to determine the effects of such interventions on asthma‐related health outcomes. We also planned to make the education interventions accessible to readers by summarising the content and components.

Search methods: We searched the Cochrane Airways Group Specialised Register of trials, which includes the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL, AMED and PsycINFO, and handsearched respiratory journals and meeting abstracts. We also searched the Education Resources Information Center database (ERIC), reference lists of trials and review articles (last search January 2011).

Selection criteria: We included randomised controlled trials of asthma education delivered in the home to children, their caregivers or both. In the first comparison, eligible control groups were provided usual care or the same education delivered outside of the home. For the second comparison, control groups received a less intensive educational intervention delivered in the home.

Data collection and analysis: Two authors independently selected the trials, assessed trial quality and extracted the data. We contacted study authors for additional information. We pooled dichotomous data with fixed‐effect odds ratio and continuous data with mean difference (MD) using a fixed‐effect where possible.

Main results: A total of 12 studies involving 2342 children were included. Eleven out of 12 trials were conducted in North America, within urban or suburban settings involving vulnerable populations. The studies were overall of good methodological quality. They differed markedly in terms of age, severity of asthma, context and content of the educational intervention leading to substantial clinical heterogeneity. Due to this clinical heterogeneity, we did not pool results for our primary outcome, the number of patients with exacerbations requiring emergency department (ED) visit. The mean number of exacerbations requiring ED visits per person at six months was not significantly different between the home‐based intervention and control groups (N = 2 studies; MD 0.04; 95% confidence interval (CI) ‐0.20 to 0.27). Only one trial contributed to our other primary outcome, exacerbations requiring a course of oral corticosteroids. Hospital admissions also demonstrated wide variation between trials with significant changes in some trials in both directions. Quality of life improved in both education and control groups over time.

A table summarising some of the key components of the education programmes is included in the review.

Authors' conclusions: We found inconsistent evidence for home‐based asthma educational interventions compared to standard care, education delivered outside of the home or a less intensive educational intervention delivered at home. Although education remains a key component of managing asthma in children, advocated in numerous guidelines, this review does not contribute further information on the fundamental content and optimum setting for such educational interventions.
