Area of Science:

• Nasal hygiene and respiratory care
• Medical device usability studies
• Subjective preference assessment

Background:

• Nasal hygiene is crucial for respiratory health.
• Several nasal hygiene systems are available, each with unique features.
• Understanding user preference is key to product adoption and adherence.

Purpose of the Study:

• To compare subjective user preference for three nasal hygiene systems: Stérimar Original, Emcur, and Sinus Rinse.
• To evaluate ease of use, comfort, and perceived effectiveness of each system.
• To identify potential differences in user experience and satisfaction.

Main Methods:

• A prospective, single-blind, randomized crossover study was conducted.
• Eighteen adult volunteers used each of the three nasal hygiene systems for three days.
• A visual analogue scale assessed instructions, ease of use, comfort, perceived nasal clearance, and overall preference.

Main Results:

• Stérimar Original provided the simplest instructions.
• Stérimar Original and Sinus Rinse were easier to use than Emcur (p < 0.05).
• No significant differences were found in comfort, perceived nasal clearance, or overall preference among the systems.

Conclusions:

• Stérimar Original offers the most user-friendly instructions.
• Stérimar Original and Sinus Rinse demonstrate superior ease of use compared to Emcur.
• User preference remained consistent regardless of cost disclosure, with no significant side effects reported.
