Comparative Efficacy of Earplug Usage Instruction (CEEUIn)
Comparative Efficacy of Earplug Usage Instruction : A Randomized Trial of Video-Based And Paper-Based Instruction
The goal of this clinical trial is to learn whether video-based training or paper-based training is more effective at teaching correct earplug insertion technique, in hospital personnel at Maharaj Nakorn Chiang Mai Hospital who work in noise-exposed areas (e.g. laundry and kitchen units), aged 20-60 years. The main questions it aims to answer are:
- Which training method ,between video-based and paper-based instruction, produces better earplug insertion skill immediately after training?
- Is any improvement in earplug insertion skill sustained at 1-week follow-up?
Researchers will compare a video-based instruction group to a paper-based instruction group to see if one training format leads to better and more lasting earplug insertion skill, as measured by a standardized 20-point observational checklist.
Participants will:
- Undergo a baseline history and ear exam (otoscopy) and complete a demographic questionnaire .
- Have their baseline earplug insertion skill assessed by a blinded observer Be randomly assigned to receive either a 5-minute video-based or paper-based instruction on proper earplug use .
- Practice inserting earplugs and then be reassessed immediately after training
- Return after 1 week for a follow-up assessment to test retention of the skill

The primary outcome is earplug insertion skill, defined as the participant's ability to correctly perform earplug insertion. Skill will be assessed using the Standardized Foam Earplug Insertion Checklist (SFEIC) , a standardized 20-point observational checklist (10 points per ear), covering key steps such as hand hygiene, earplug preparation, insertion technique, and fit verification. Each item is scored as correct (1 point) or incorrect (0 points), for a total score ranging from 0 (minimum) to 20 (maximum). Higher scores indicate better (more correct) earplug insertion technique. Participants will be asked to demonstrate earplug insertion, and performance will be evaluated by trained assessors blinded to group allocation. |
