Clinical Trial Summary

This trial aims to investigate whether analgesic ear drops added to usual care provide superior ear pain relief over usual care alone in children presenting to primary care with AOM. Children will be randomly allocated (ratio 1:1) to either 1) lidocaine hydrochloride 5mg/g ear drops (Otalgan) 1-2 drops up to six times daily for a maximum of 7 days in addition to usual care (oral analgesics, with/without antibiotics) or 2) usual care. Parents will complete a symptom diary for 4 weeks as well as generic and disease-specific quality of life questionnaires at baseline and 4 weeks. The primary outcome is the parent-reported ear pain score (0-10) over the first 3 days. NOTE: At the time of publication of the study protocol paper, the investigators were unable to make any amendments to the trial registration record in the Netherlands Trial Register (NTR) (NL9500; date of registration: 28 May 2021). The addition of a data sharing plan was required to adhere to the International Committee of Medical Journal Editors (ICMJE) guidelines. The investigators therefore re-registered the trial in ClinicalTrials.gov. This second registration is for modification purposes only and the NTR record (NL9500) should be regarded as the primary trial registration.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The parent-reported ear pain score over the first three days	Parents will record their child's ear pain scores during the first three consecutive days using a 0-10 validated numerical rating scale. Higher scores indicate greater severity.	3 days
Secondary	proportion of children consuming antibiotics		in the first 7 days
Secondary	proportion of children with oral analgesic use		in the first 7 days
Secondary	overall symptom burden (crying/distress, disturbed sleep, interference with normal activity, appetite, fever and hearing problems) using a 0-6 Likert scale	higher scores indicate greater severity	in the first 7 days
Secondary	number of days with ear pain		during follow up (4 weeks)
Secondary	number of GP reconsultations with/without subsequent antibiotic prescribing		during follow-up (4 weeks)
Secondary	number of participants with adverse events		during follow-up (4 weeks)
Secondary	number of participants with complications of AOM		during follow-up (4 weeks)
Secondary	costs	Mean costs per patient will be compared across the randomisation groups	during follow-up (4 weeks)
Secondary	generic quality of life of the child assessed using the 47-item short-form of the Infant Toddler Quality of Life Questionnaire (ITQOL-SF47)	The questionnaire consists of 47 items in the following areas: overall health, physical abilities, growth and development, pain, temperament and moods, behavior, general health, parental emotional impact, parental time impact, and family cohesion. Scale for each area: from 0 (worst health) to 100 (best health)	at baseline and at 4 weeks
Secondary	disease-specific quality of life of the child assessed using the Otitis media-6 (OM-6) questionnaire	The 6 questions measure Physical Suffering, Hearing Loss, Speech Impairment, Emotional Distress, Activity Limitations, and Caregiver Concerns. Responses for each item were scored from 1 to 7 (1=Not present/no problem; 2=Hardly a problem at all; 3=Somewhat of a problem; 4=Moderate problem; 5=Quite a bit of a problem; 6=Very much of a problem; 7=Extreme problem). A mean score of all six items comprises the OM Total Score. Higher mean scores of all six items indicate greater severity and impact of OM on the child's QOL.	at baseline and at 4 weeks
Secondary	incremental cost-effectiveness ratios; calculated by dividing the estimated differences in costs between groups by the differences in effects observed	i.e. the additional cost per additional 1 point reduction in mean ear pain score over the first three days for the analgesic ear drops group versus the usual care group	during follow-up (4 weeks)
