ABSTRACT
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.

BACKGROUND: Newborn screening for cystic fibrosis (CF) is effective in improving long-term growth outcomes. However, there is conflicting evidence that early diagnosis maintains normal pulmonary function. Our goal was to determine if newborn screening results in improved longitudinal growth and maintenance of normal pulmonary function. METHODS: A retrospective study of individuals with CF born in Connecticut between 1983 and 1997 was conducted by medical record and CF Foundation Registry review. Growth, pulmonary function and bacterial acquisition/colonization data, from diagnosis through July 1, 2005, were compared in those diagnosed by newborn screen (n = 34) to those diagnosed by sweat test after symptom appearance (n = 21). RESULTS: Screened individuals demonstrated greater weight and height for age at diagnosis (P = 0.01 and 0.01) and through 15 years of age (P = 0.0002 and 0.01). Body mass index was higher in screened individuals (21 vs. 18 kg/m(2)) at 15 years of age (P = 0.01). At 15 years of age, screened individuals had a clinically higher forced expiratory volume in 1 second (FEV(1)) and forced vital capacity (FVC; 90% and 104% predicted) than non-screened individuals (74% and 91% predicted; P = 0.08 and 0.10). Over a 9-year period, from ages 6 to 15, percent predicted FEV(1) and FVC increased by 4% and 13% in screened individuals; and declined by 14% and 5% respectively in non-screened individuals (P = 0.01 and 0.02). Acquisition/colonization of Pseudomonas aeruginosa was similar between groups (P = 0.23). CONCLUSIONS: In this CF cohort, individuals diagnosed by newborn screening have improved growth and preservation of normal pulmonary function without increased risk of Pseudomonas aeruginosa colonization.
