Plain English Summary

Background and study aims
Middle ear infections (medical term: acute otitis media or AOM) are common painful infections in children. Germs multiply in the confined middle ear resulting in a build-up of pressure that stretches the ear drum. In around 1 in 7 children, the ear drum bursts, releasing a liquid (medical term: discharge or otorrhoea) that can be seen coming out of the ear. It is commonly believed that the pain of AOM improves when the ear drum bursts, but research shows that the pain is similar with or without the ear drum bursting. At the moment nearly all UK children with AOM and discharge (AOMd) seen by their GP/nurse are treated with antibiotics by mouth. These can cause side effects like rashes, diarrhoea and vomiting and more rarely, severe allergic reactions. They can also make the germs in a child’s body resistant to antibiotics. It may be possible to use alternative treatments for ear discharge. One possibility is to use antibiotic eardrops. Research has shown these are better than antibiotics by mouth for children with runny ears and grommets, probably because the antibiotics are given directly to the place they are most needed. Another potential treatment is a ‘delayed’ antibiotic prescription (where parents are advised to wait to see if the child’s infection improves without antibiotics). Studies in other infections suggest this can be just as effective and safe, but with fewer side effects. Since AOMd is painful and distressing for children and their families it is important to show that any new treatments work at least as well as the current standard treatment (immediate antibiotics by mouth). The aim of this study is to test whether giving an antibiotic ear drop or a delayed antibiotic by mouth is as good as immediately giving antibiotics by mouth for children (without grommets) who have developed AOMd.

Who can participate?
Children aged 1 to 16 with AOMd

What does the study involve?
Participants are randomly allocated to one of three treatments: immediate antibiotic ear drops, delayed oral antibiotics or immediate oral antibiotics (usual care), all for 7 days. AOMd symptoms (pain, fever, being unwell, sleep disturbance, discharge, and episodes of distress) are assessed at the start of the study and after 14 days.

What are the possible benefits and risks of participating?
The NHS has paid for and approved this study because evidence suggests the treatment might work. Participants will be helping research to improve the future treatment for children with ear discharge. Risks include possible allergic reactions to the antibiotic drops or antibiotics taken by mouth, but the medicines are routinely prescribed in the UK and are considered safe to use for children. The advice to gently press on the outer ear flap to help the ear drops flow into the ear hole may cause discomfort to some children. If this happens, it is not necessary to continue using the “pumping” method but to simple keep the child’s head tilted to one side for a few extra minutes, to make sure the drops have reached the ear drum. The collections of the stool samples may prove to be a sensitive issue, and therefore the stool sample collection is optional.

Where is the study run from?
175 GP practices (to be determined) (UK)

When is the study starting and how long is it expected to run for?

Scientific title

Immediate oral, immediate topical or delayed oral antibiotics for acute otitis media with discharge: the Runny Ear STudy (REST)

Acronym

REST

Study hypothesis

To determine whether either ciprofloxacin 0.3% drops, or delayed oral amoxicillin (clarithromycin if penicillin allergic or other suitable oral antibiotic as chosen by the GP), is non-inferior to current usual care (immediate oral antibiotics) for overall illness duration in children with Acute Otitis Media (AOMd) presenting to primary care.

Condition

Acute otitis media with discharge (AOMd)

Intervention

Children will be randomised, stratified by age (<2 years and ≥2 years, since children <2 years’ experience longer illness duration). Two randomisation lists will be generated as per the stratification. Blocks of 12 will be used for allocation (4 in each arm), since most practices will recruit one or two patients only. The sequence will be supplied to the TRANSFoRm platform to be allocated to each successive participant recruited.

1. Immediate topical ciprofloxacin (0.3%) solution, four drops three times daily for 7 days with written advice regarding how to administer drops
2. Delayed ‘dose-by-age’ amoxicillin suspension three times daily (clarithromycin twice daily if penicillin allergic or other suitable oral antibiotic as chosen by the GP) for 7 days, with structured delaying advice
3. Immediate 'dose-by-age' amoxicillin (clarithromycin) for 7 days (usual care)

Follow up will be 3 months.

Phase

Phase IV

Drug names

Ciprofloxacin, amoxicillin, clarithromycin

Primary outcome measures

Time to resolution of all of the following:
1. Pain
2. Fever
3. Being unwell
4. Sleep disturbance
5. Otorrhoea
6. Episodes of distress/crying being rated ‘no’ or ‘very slight’ problem (without need for analgesia)
Recorded by parents/carers using a validated Symptom and Recovery Questionnaire (SRQ) with Research Nurse telephone support at baseline to 14 days after randomisation

Secondary outcome measures

Secondary outcomes will include (as recorded in the first 14 days of participant entry to the trial on the symptom
recovery questionnaire):
1. Time until symptoms (pain, fever, being unwell, sleep disturbance, otorrhoea, episodes of distress/crying, appetite
and interference with normal activities) are no longer rated ‘moderately bad or worse’ (score of ≥3 on validated
scale) measured using the symptom recover questionnaire
2. Adverse events diarrhoea, rash, vomiting and severe complications measured on the symptom recovery questionnaire at day 7 and 14
3. Parent carer satisfaction with treatment is measured on the symptom recovery questionnaire at day 14
4. Treatment adherence and analgesic use to symptom resolution is measured using the symptom recovery questionnaire up to day 14
5. Details of NHS resource use is measured using the symptom recovery questionnaire at day 7 and 14
6. Burden of resistance is measured using stool sample at day 7 and 3 months
