Analgesic Ear Drops for Children With Acute Otitis Media

Phase 3TerminatedNCT05651633

UMC Utrecht29 enrolled

Overview

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.

Outcomes

Primary Outcomes

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.

Time frame: 3 days

Secondary Outcomes

Proportion of Children Consuming Antibiotics

proportion of children consuming antibiotics during first 7 days

Time frame: in the first 7 days

Proportion of Children With Oral Analgesic Use

proportion of children with oral analgesic use during first 7 days

Time frame: in the first 7 days

Overall Symptom Burden (Crying/Distress, Disturbed Sleep, Interference With Normal Activity, Appetite, Fever and Hearing Problems) Using a 0-6 Likert Scale

overall symptom burden (crying/distress, disturbed sleep, interference with normal activity, appetite, fever and hearing problems) using a 0-6 Likert scale with higher scores indicate greater severity

Time frame: in the first 7 days

Number of Days With Ear Pain

Number of days with pain score of 1 or greater on a scale of 0-10, where higher scores indicate greater pain".

Time frame: during follow up (4 weeks)

Number of GP Reconsultations With/Without Subsequent Antibiotic Prescribing

Time frame: during follow-up (4 weeks)

Number of Participants With Adverse Events

Proportion of participants experiencing adverse events during follow-up

Time frame: during follow-up (4 weeks)

Number of Participants With Complications of AOM

Time frame: during follow-up (4 weeks)

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)

Time frame: At 4 weeks

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). The OM Total score was calculated by adding all 6 items scores, resulting in a score ranging from 6-42. Higher scores of all six items indicate greater severity and impact of OM on the child's QOL.

Time frame: At 4 weeks

Costs

Mean costs per patient will be compared across the randomisation groups

Time frame: during follow-up (4 weeks)

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

Time frame: during follow-up (4 weeks)
