The early use of Antibiotics in at Risk CHildren with InfluEnza

www.archiestudy.comTwitter: @archiestudy

Chief Investigator: Dr Kay WangSenior Trial Manager: Tricia Carver

Research questions

• Does early antibiotic use in ‘at risk’ children with influenza-like illness reduce the likelihood of re-consultation due to clinical deterioration?

• What impact might early antibiotic use have on antimicrobial resistance?

• Is early antibiotic use cost effective?

Recruitment plan

• 650 ‘at risk’ children with influenza-like illness

• Winters 2014/5 and 2015/6 (+/- 2016/7)– October to March – Bulk of recruitment during peak influenza season

(December/January)

• Target: 8 recruits per site per season (2 per month)

Patients to consider for ARCHIE

• ‘At risk’ children aged 6 months to 12 years

• Cough AND fever (fever reported as symptom or temperature 37.9°C or higher during consultation)

• Within 5 days of symptom onset

• No known contraindication to co-amoxiclav

• Does not require immediate antibiotics or hospitalisation

Archie is more ill than usual when he just gets a cold or flu………

………………but I’m not sure if he is ill enough to need antibiotics.

Recruitment timeframe

• Same day if possible

• Following (working) day if still meet eligibility criteria– Complete eligibility assessment form on the same

day as the baseline appointment

Study enrolment (face to face)• Full eligibility assessment• Baseline assessment

• Introduce the study • Initial eligibility assessment (healthcare professionals)• Eligibility criteria and information leaflets available

from www.archiestudy.com

Triage nurse ClinicianReceptionist

Recruitment tip 1• Ask parents and children to read the study

information leaflets before the baseline appointment

• Patients can go to www.archiestudy.com to:– Watch video clips about the study– Download study information leaflets– Read our Frequently Asked Questions

Baseline appointment (day 1)

• To be completed by healthcare professional– Eligibility assessment – Consent +/- assent– Baseline clinical assessment– Randomise and allocate study medication– Contact card

• To be completed by parent/guardian ± child– Contact information form– Questionnaires (two for parent, one for child)– Study diaries

Recruitment tip 2

• Use the armpit thermometer provided to take the child’s temperature, and show the parent how to use it at the same time

Recruitment tip 3• While you prepare the child’s study

medication, ask the parent and child to:– Complete the contact information form– Complete the study questionnaires– Look through the Diary – Instructions and

Overview

Study medication • Co-amoxiclav 400/57 or matching placebo• Randomisation system accessible via website• Key instructions for parents:– Keep medication refrigerated once reconstituted– Give first dose as soon as possible (consider during

baseline appointment)– Can repeat dose if child vomits within 30 minutes

of dose– Give child maximum of 10 doses– Discard leftover medication

Follow-up assessments

• Telephone follow-ups– Week 1 (day 7 to 10)– Week 2 (day 14 to 17)

• Objectives– Safety monitoring– Reminders to complete and return diaries

• No need to ask consent for follow-up throat swabs for children who have not been recruited from a GP surgery

Reimbursement

• Service support costs – Insert region specific details

• Research costs– Reimbursed annually by study team– £16.48 per child recruited into trial

FAQ- reconsultationQ: What is the procedure if a child reconsults because they are unwell while they are still taking their study medication?

A: The clinician should assess and manage the child as they would based on their usual clinical practice. This may include issuing a prescription for antibiotics if the clinician considers that antibiotic treatment is indicated. The BNF states that the standard dose of co-amoxiclav can be doubled* when treating severe infections. The study medication dosing regimen in ARCHIE is based on the BNF standard dosing regimen. The child can therefore continue taking their study medication unless there is a reason to stop it (e.g. suspected allergic reaction).*caution advised in children with underlying conditions which may compromise the excretion or metabolism of co-amoxiclav, and in children weighting less than 6kg. In these children, an alternative antibiotic should be considered.
