Vibrating-mesh nebulizer maintenance by CF patients: Results from a French survey.

PURPOSE OF THE STUDY: Vibrating-mesh nebulizers are widely used at home for cystic fibrosis (CF) treatment, with a therapeutic efficiency closely linked to the mesh performance. This national study looks at the maintenance at home by CF patients and their families of the mesh of the eFlow® rapid nebulizer. Ninety-two patients from 34 French CF centers, treated at home with inhaled drugs delivered with a vibrating-mesh nebulizer, answered to a phone standardized questionnaire specifying the different techniques of maintenance of the nebulizer.

PRINCIPAL RESULTS: Patients were aged from 2 to 68 years (58.7% of children). They inhaled a mean of 1.8 nebulizations per day. Maintenance was assumed by patients in 36% of the cases. All steps of the theoretical maintenance of a nebulizer were respected in 66% of the cases. The mesh was not cleaned in 45.6%, not disinfected or not thermically disinfected in 32.5%, and not rinsed after chemical disinfection in 45.5% of the case. Only 49% of the patients knew the role of the MeshCare® system in the mesh maintenance, and only 39% had already used it when the nebulization duration reached 10 min.

CONCLUSIONS: Efforts about education, particularly for the maintenance of the mesh, are needed for CF patients using a vibrating-mesh nebulizer at home.
