Infection Control - Sanitizing Via Ultraviolet?

Question

What are your thoughts on sanitizing hearing aids via the ultraviolet light of the Dry and Store® box?

Answer

The Dry and Store is a hearing aid dehumidifier. Some Dry and Store models (excluding the Zephyr) come with an ultraviolet light which claims to sanitize hearing instruments. The process is a three-minute cycle. Bear in mind, however, that prior to putting a hearing instrument in the Dry and Store, a patient must first wipe the hearing instrument to remove any visible contamination such as cerumen. Once the hearing instrument is placed in the Dry and Store and the lid is closed the ultraviolet light, located at the top of the lid, will illuminate. Keep in mind, when you close the lid of the Dry and Store, the ultraviolet light will only shine on that part of the hearing instrument that is in the direct line of sight of the ultraviolet light;in other words, the light will only shine on the part of the hearing instrument that is exposed to the light. From this perspective, it is important to do two things. First, since the UV radiation can only kill germs on that part of the hearing instrument exposed to the light, using a disinfectant towelette to disinfect the hearing instrument prior to placing it in the unit is a good idea to ensure all surfaces have been disinfected. Second, encourage patients to rotate or change the position of the hearing instrument in the Dry and Store from day to day so that all surfaces of the hearing instrument are exposed to the ultraviolet light.
