A Survey of Cystic Fibrosis Center Recommendations for Nebulizer Cleaning and Disinfection.

Abstract

Despite advancements in cystic fibrosis (CF) therapeutics, the persistence of chronic infections necessitates continued use of nebulized therapies. Though the Cystic Fibrosis Foundation recommends well-defined cleaning and disinfection of nebulizers to mitigate pathogen exposure risks, discrepancies between Cystic Fibrosis Foundation guidelines, manufacturers' instructions, and variability in center recommendations contribute to confusion and non-standardized practices. A digital survey was distributed to directors, associate directors, and care coordinators of CF centers across the United States to investigate the methods, frequency, and educational practices surrounding nebulizer care they provide patients. Responses were analyzed using descriptive techniques and chi-square analyses. Of 855 distributed surveys, 129 respondents provided insights into nebulizer care recommendations. Discrepancies in disinfection frequency were notable, with 18% of respondents recommending disinfecting nebulizers less than daily. Approximately 20% of respondents were unsure if their recommendations aligned with Cystic Fibrosis Foundation guidelines while 73% reported that their recommendations strictly adhered to the published guidelines. Of this 73%, all recommended at least daily cleaning, with 69% specifying cleaning before reuse; and 88% recommended disinfection at least daily, with 36% specifying disinfection before reuse. Only 10% recommended both cleaning and disinfection after every use. Disinfection less than daily was recommended by 11% of the respondents who felt they were strictly following the guidelines. We also highlight respondents who cited barriers to strict adhesion to the published guidelines. The highlighted variations in CF centers' recommendations for nebulizer care with deviations from Cystic Fibrosis Foundation guidelines underscore the necessity for developing clear and practical guidelines that consider both efficacy and the realities of patient adherence. Collaboration among CF care centers, patients, guideline committees, and other stakeholders is essential to develop recommendations that effectively address the challenges faced by the CF community, ensuring the safe and effective nebulizer use.
