Nebulizer cleaning and disinfection practices in families with cystic fibrosis: The relationship between attitudes, practice and microbe colonization.

BACKGROUND

The daily burden of health maintenance for children and families with cystic fibrosis (CF) is immense with respect to time and complexity of care. Infection control practices, specifically nebulizer cleaning and disinfection, are a recommended component of home health care for CF families due to colonization of home respiratory equipment with lung pathogens. To better inform education interventions at our center, we were interested in studying how families' views on infection prevention and awareness of CF Foundation infection prevention and control (IP&C) guidelines correlate with actual home nebulizer care and the presence of microorganisms on their nebulizers.

METHODS

Twenty families who have children with CF were surveyed to better understand attitudes toward infection prevention, awareness of CFF IP&C guidelines and nebulizer cleaning and disinfection practices in the home. Their nebulizers were also cultured for microbes to correlate recovery with infection control behaviors.

RESULTS

A subset of families recognizes the importance of germ avoidance but do not recognize nebulizer cleaning and disinfection as very important for infection control practices. Decreased frequency of disinfection, but not cleaning, was correlated with the recovery of organisms on the nebulizers.

CONCLUSIONS

The study questionnaire results identify a gap between recognizing the importance of infection prevention and consistently implementing CFF IP&C guidelines in the home. This demonstrates the need at our center for new educational interventions to promote cleaning and disinfection of home nebulizers after each use as recommended by the CFF.
