Scientific title
Study acronymCHARISMA
Study objectivesThe aim of the study is to evaluate the effectiveness and cost-effectiveness of improving ventilation in heating in the homes of children with moderate or severe asthma who live within Wrexham.
Ethics approval(s)North East Wales Local Research Committee approved of the trial on the 30th July 2003.
Health condition(s) or problem(s) studiedModerate or severe asthma in children
InterventionPragmatic randomised controlled trial with delayed-implementation controls: analysis by intention to treat. Patients are identified from GP records. Remote randomisation is stratified by GP practice, whether central heating needs improving, childs age and gender, type of housing, and household smoking status.

A package of housing improvements designed to provide adequate ventilation and temperatures and to reduce mould spores:
1. If the recruited child has one or more siblings who suffer from asthma and sleep in a different room, the housing department install a whole-house ventilation system. Otherwise they install a single-room ventilation unit
2. Improvements to bring central heating to a defined standard, if required

The control group are offered the same installation package 12 months later, after the final follow-up questionnaire has been returned.
Intervention typeOther
Primary outcome measure(s)

Parental assessment of the child's asthma-specific quality of life (PedQL asthma module) four and twelve months after randomisation. Baseline PedQL will be used as a covariate.

Key secondary outcome measure(s)

1. General health-related quality of life (PedQL core module), school attendance and the use of health care including medication
2. An economic analysis will compare costs
