Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Children who are less than 6 years old who present with wheezing to the Emergency Department, or admitted to Children’s ward or Paediatric Short Stay Unit, will be recruited by medical or nursing staff. Each child will then be randomly assigned to provision of either Asthma Action Plan (AAP) or Pre-school Wheeze Action Plan (PSWAP). Discharge instructions will be given according to the action plan each child has been assigned to. The discharging medical or nursing staff will then answer a 5-minute questionnaire to determine satisfaction and ease of discharge instructions. The family of each child will be contacted at 2 weeks, 6 weeks, and then 3 months via telephone to answer a 5-minute questionnaire to determine parent satisfaction & understanding of their child’s condition in relation to the action plan, as well as adherence to the action plan.

Treatment: Other
Comparator / control treatment
Asthma action plan, template derived from standardized asthma action plan that is used state wide.
The headings of this paln incude when to administer ventolin when well, unwell or recognition of danger signs and critical asthma.
Asthma action plan is usually administerd by nursing or medical staff at the time of presentation to emergency department or admission to the paediatric short stay unit or paediatric ward.
Asthma action plan or the intervention (Preschool wheeze action plan) is a written document that will be provided at the initial contact with participants.
Patients that do not consent to be part of the study will still be provided with an Asthma action plan as standard practice of the hosptial.
Control group

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A computer randomization software program (in house software) will be used to generate a sequential list of participants (identified by study number) randomized to either of the 2 study groups. Prior to the study commencing, this randomized list will be used to prepare a set of ordered, sealed envelopes, each containing the appropriate action plan and medical staff questionnaire.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computer randomization software program (in house software) will be used to generate a sequential list of participants (identified by study number) randomized to either of the 2 study groups.

SAMPLE SIZE ESTIMATION & JUSTIFICATION
It is anticipated that 300 children will be required for meaningful statistical analysis. This number is in excess of the power calculations as indicated below.
POWER CALCULATIONS
Questionnaire on Satisfaction.
•It is assumed that the questions will have a rating scale of from 1 to 4 and that significance will be assessed via a comparison of means. Using a random number generator, 100 values were generated between 1 and 4, The mean was 2.41 and SD was 0.12. Calculations using the UCSF Clinical and Translational Science Institute Sample Size Calculator:
•Alpha (2 tailed) = 0.05, beta = 0.2 and a SD of 0.12, a sample size of 90 for both intervention and control groups gave an effect size of 0.05. This corresponds to there being sufficient power in a sample size of 90 to detect a difference of 2% between the intervention and control groups.
•A sample size of 90 is consistent with similar prospective studies in which a patient satisfaction survey was performed (1).

Comparison of visits to GPs and ED following a wheeze exacerbation.
•This data will result in 2 frequency distributions (1 for the intervention, 1 for the control), for 1, 2, 3 or 4 or more visits within a specified period.
•At a basic level this will allow a categorical comparison between groups for each number of visits, most likely via Chi Square.
•Using the UCSF Clinical and Translational Science Institute Sample Size Calculator:
•Alpha (2 tailed) = 0.05, beta = 0.2, proportions in both groups = 0.5, baseline risk = 0.3 and an OR of 0.5, calculated a sample size needed of 202. This corresponds to there being sufficient power in a sample size of 202 to detect a 50% reduction in GP attendances in the intervention group when compared to control for one of the frequency categories (eg 1 visit to a GP or ED following an exacerbation). Depending on the strength of study findings, the above frequency categories may need be combined to provide adequate power.
•A sample size of 200 is consistent with similar prospective studies in which ED visits were reduced by altered strategies (2).
