Bronchiolitis / Paracetamol in infancy: a feasibility study
Scientific title
Is it feasible to undertake a multi-centre randomised control trial of paracetamol versus another anti-pyretic (or placebo) in infants aged between 6 months and 2 years who have been admitted to hospital with a clinical diagnosis of bronchiolitis, to see if there is increased risk of wheezing and atopy by age 3.

Health condition
Health condition(s) or problem(s) studied:
Asthma
Although we are looking at recruit from a population of infants that have been diagnosed with bronchiolitis, this is because we know that this population has a higher risk of developing wheezing and atopy in childhood, so we believe our likely incidence of asthma by the age of three will be higher in this population than in the general population. 288592 0

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Study undertaken in 2 parts.
Module one: questionnaire administered to all parents / guardians of infants admitted to hospital with bronchiolitis to establish their likelihood of participating in a larger longer term study AND to establish preferred comparator to paracetamol (out of placebo, ibuprofen or paracetamol only according to WHO guidelines). Module one to be completed by December 2013.
Module two: Enrollment of 50 participants in Module one into an open label 3-month trial, comparing paracetamol use 'as usual' (in accordance with manufacturers guidelines: 15-20mg /kg, up to 4 times per day, and child to see GP if still problematic after 3-4 days of treatment) with paracetamol only according to WHO guidelines (give 15mg / kg paracetamol only when child has temperature greater than 38.5 degrees AND / OR when child appears to be in significant pain, and only for the shortest period of time). Module Two to be completed by December 2013

All paracetamol is in oral syrup form.
Intervention code [1] 286694 0
Treatment: Other
Comparator / control treatment
INTERVENTION arm is paracetamol only according to WHO guidelines for infants (when child has temperature greater then 38.5 degrees AND / OR appears to be in significant pain)

CONTROL / COMPARATOR arm is paracetamol for infants as would usually be given by parents / guardians

This is a feasibility study designed to find out whether parents would enroll their infants in a future, larger study involving placebo / ibuprofen / or WHO restricted paracetamol, BUT we have no intentions of trialing either placebo or ibuprofen in THIS study. Instead Module One is a questionnaire designed to find out which possible alternative / intervention arm parents would be most comfortable with in a future hypothetical study.

Module Two is the intervention part of the study and the only two arms are paracetamol as parents would normally administer it (as previously described) and paracetamol according to WHO guidelines (also previously described).

There is no placebo in THIS study, so have left the question below as 'Active'
Control group
Active

Outcomes
Primary outcome [1] 289048 0
Module One:
a. the proportion of parents / guardians who would enroll their infant in a long term study where they would have a 50% chance of being allocated to paracetamol use as they would normally give it, or to an alternative arm consisting of restricted paracetamol use OR ibuprofen OR placebo.

Will be assessed as follows:
1. Derived from the answers given in the questionnaire in Module One
Timepoint [1] 289048 0
End of Module One - estimated December 2013
Primary outcome [2] 289049 0
Module One
b. Parental / guardian preference for comparator group (restricted paracetamol, ibuprofen or placebo)
- assessed by evaluating answers given in questionnaire to Module One
Timepoint [2] 289049 0
End of Module One - anticipated December 2013
Primary outcome [3] 289050 0
Is there a statistical difference in paracetamol dosing between the group allocated to paracetamol as usual and the groups allocated to restricted paracetamol

Assessed by capturing paracetamol usage for both groups in a study diary kept by parents over a three month period, and doing T-square test to assess if there is a statistically significant difference in the amounts used by both groups
Timepoint [3] 289050 0
End of Module Two - anticipated end December 2013
Secondary outcome [1] 301636 0
Qualitative assessment of the tools / methods used in the feasibility study
- participants in Module Two will be asked for qualitative feedback by questionnaire

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Module One: enrollment for questionnaire only which will only be undertaken after informed consent obtained
Module two: enrollment of infant and parent(s) / guardian(s) into study after informed consent. Statistician to generate a random allocation programme ensuring 25 participants allocated to paracetamol as usual and 25 to restricted paracetamol use. Neither participants nor researchers will know intervention arm until envelope is opened with allocation slip inside. Study is not blinded, so after envelope is opened researchers and participants will know intended study intervention.
