Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention: Prednisolone.
Prednisolone is a corticosteroid that has strong evidence for effectiveness in reducing the length of facial palsy symptoms in adults suffering from Bell's palsy.
Participants assigned to the intervention will receive 1mg/kg/day of prednisolone (dosing is based on weight categories) up to a maximum of 50mg/day for 10 days.
The prednisolone will be administered as an oral solution as a once daily dose.
Strategies used to monitor adherence will be a survey relating to compliance at the end of the 10 day course of treatment, in addition to the return of the bottles.
Intervention code [1] 291803 0
Treatment: Drugs
Comparator / control treatment
control treatment: placebo.
The placebo will be supplied in glass bottles identical to the intervention by the same supplier that produces the intervention. It will be manufactured to look and taste identical to that of the intervention
The placebo will be an oral liquid with the same ingredients as the intervention solution minus the active drug, prednisolone.
Control group
Placebo

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)
in the event of a child being diagnosed with Bell's palsy, a senior doctor from the ED or a member of the resarch team will review the medical history for initial determination of eligibility. They will then approach the potential participant to explain the study to them, and conduct the informed consent process.
Once written informed consent has been obtained, demographic information and medical history will be elicited. Study eligibility will be confirmed and the patient will be randomised.
To randomise the patient, the senior doctor or the research team will select the lowest number study pack. This study pack will either contain prednisolone or placebo made up by the central study pharmacist according to a computer generated randomisation schedule.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will be randomised stratified by site in a 1:1 ratio to one of two treatment arms: intervention (prednisolone) or matched placebo.
An independant statistician will generate a randomisation schedule using variable block sizes, stratified by site.
This schedule will be used by the central phyarmacist at RCH to undertake the blinding, labelling and distribution of the study drugs to participating sites by putting together study packs of the required drug labelled with sequential study numbers for each site.
Randomisation at the site will be undertaken at the site by the doctor or research team by selecting the lowest numbered study pack (next pack system) from the study drug store in the ED

Efficacy
Statistical methods / analysis
Sample size estimation:
The primary outcome is the proportion of subjects who have complete recovery at 1 month post randomisation. Based on our observational data, we expect 60% of children without prednisolone to have complete recovery at 1 month. A study in adults found an improvement of 12% with prednisolone compared with placebo which was deemed to represent a clinically important difference.
To enable us to identify an increase in recovery from 60% to 72% or larger with 80% power requires a study with 244 subjects in each treatment group based on a two-sided test with a=0.05. Hence we aim to recruit 270 per group (540 in total) to allow for 10% loss to follow-up at 1 month.
Statistical Analysis:
Data will be analysed on an intention-to-treat basis where primary outcome data are available.
Primary outcome will be presented as a difference in proportions in each treatment group, with a comparison between the groups presented as a difference in proportions and as an odds ratio from a logistic regression model adjusted for site, with a 95% CI and p-value.
Secondary outcomes will be summarised by treatment group. Binary outcomes will be presented as proportions, with comparisons betwen the groups presented as a difference in proportions and as odds ratios from logistic regression adjusted for site, with 95% CIs and p-values.
