Description of intervention(s) / exposure
Additional asthma education intervention by local Health Workers with children and their parents.

The children selected to receive the intervention (additional asthma education) will receive a personalised child friendly booklet and will have three visits from the health worker for their asthma (about 1 month, 3 months and 6 months after the clinical consultation). All children will be followed up for 12 months (from the day of 1st clinical assessment).

Outcomes
Primary outcome [1] 1230 0
Number of unscheduled hospital/doctor visits due to asthma exacerbation during the 12 months follow up period.
Timepoint [1] 1230 0
Primary outcome will be measured at the end of the follow up period through medical chart review.
Secondary outcome [1] 2236 0
Quality of life: we will use the Paediatric Asthma Quality of Life Questionnaire that has been shown to have good measurement properties and is valid both as an evaluative and a discriminative instrument capturing aspects of asthma most important to the patient and adding additional information to conventional clinical outcomes.
Timepoint [1] 2236 0
Secondary outcomes will be measured at the end of the follow-up period (12 months from the 1st clinically re-accessed) when the child is clinically reassessed.
Secondary outcome [2] 2237 0
Functional severity score : we will use questions related to the functional severity score designed by Rosier et al.
Timepoint [2] 2237 0
Secondary outcomes will be measured at the end of the follow-up period (12 months from the 1st clinically re-accessed) when the child is clinically reassessed.
Secondary outcome [3] 2238 0
If the child is on regular medications for asthma, basic knowledge of medications and the delivery technique of the child will be assessed. Basic knowledge on medications of all parents and children aged 11 or more years, will be assessed by a score of 1-5 in each of the 3 categories: (a) name of medications, (b) dose of medications, (c) how drugs work. - medication use - Asthma Action Plan (readily available, can parent interpret?).
Timepoint [3] 2238 0
Secondary outcomes will be measured at the end of the follow-up period (12 months from the 1st clinically re-accessed) when the child is clinically reassessed.
Secondary outcome [4] 2239 0
Number of days missed school due to asthma.
Timepoint [4] 2239 0
Secondary outcomes will be measured at the end of the follow-up period (12 months from the 1st clinically re-accessed) when the child is clinically reassessed.
Secondary outcome [5] 2240 0
Number of exacerbations of asthma.
Timepoint [5] 2240 0
Secondary outcomes will be measured at the end of the follow-up period (12 months from the 1st clinically re-accessed) when the child is clinically reassessed.
Secondary outcome [6] 2241 0
Number of unscheduled hospital/doctor visits (through a medical chart review).
Timepoint [6] 2241 0
Secondary outcomes will be measured at the end of the follow-up period (12 months from the 1st clinically re-accessed) when the child is clinically reassessed.
Secondary outcome [7] 2242 0
Spirometry results (for those over 6 years).
Timepoint [7] 2242 0
Secondary outcomes will be measured at the end of the follow-up period (12 months from the 1st clinically re-accessed) when the child is clinically reassessed.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Children will be randomly selected to be included in the intervention arm of this study. Informed consent will be obtained by a member of the research team from the carer(s) before enrolment. Children enrolled into the study will be randomised to one of the two groups (no additional intervention or additional education). Each child will be allocated to the next treatment regimen on a list, which will be previously generated, in random order, at the Queensland Institute of Medical Research, Queensland. A black sticker will obscure the next treatment group and will only be removed after enrolment.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Permutated block design by computer generation. Informed consent will be obtained before enrolment. Children will be randomized within strata of age.
Masking / blinding
