Resumo: | ABSTRACT Objective: Home nebulizers are routinely used in the treatment of patients with cystic fibrosis (CF). This study aims to evaluate the contamination of nebulizers used for CF patients, that are chronically colonized by Pseudomonas aeruginosa, and the association of nebulizer contamination with cleaning, decontamination and drying practices. Methods: A cross-sectional, observational, multicenter study was conducted in seven CF reference centers in Brazil to obtain data from medical records, structured interviews with patients/caregivers were performed, and nebulizer’s parts (interface and cup) were collected for microbiological culture. Results: overall, 77 CF patients were included. The frequency of nebulizer contamination was 71.6%. Candida spp. (52.9%), Stenotrophomonas maltophilia (11.9%), non-mucoid P. aeruginosa (4.8%), Staphylococcus aureus (4.8%) and Burkholderia cepacia complex (2.4%) were the most common isolated pathogens. The frequency of nebulizers’ hygiene was 97.4%, and 70.3% of patients reported cleaning, disinfection and drying the nebulizers. The use of tap water in cleaning method and outdoor drying of the parts significantly increased (9.10 times) the chance of nebulizers’ contamination. Conclusion: Despite the high frequency hygiene of the nebulizers reported, the cleaning and disinfection methods used were often inadequate. A significant proportion of nebulizers was contaminated with potentially pathogenic microorganisms for CF patients. These findings support the need to include patients/caregivers in educational programs and / or new strategies for delivering inhaled antibiotics. |
