Early Intervention in Pulmonary Exacerbation in Cystic Fibrosis

This study will be performed at the University of Washington. Forty subjects with Cystic Fibrosis will be enrolled, with 20 randomized into the usual care arm and 20 randomized into the intervention arm. All subjects will be enrolled for 6 months and have 3 study visits. One at baseline, midpoint, and final. The intervention arm subjects may have more study visits depending on their respiratory symptoms. The intervention arm subjects will perform home spirometry twice a week with a PiKo-6 hand held spirometer. They will also have a home-based telemonitoring system connected to their phone line. They will be prompted twice a week to answer questions regarding their health via the telemonitor. Subjects who are not able to utilize the home-based telemonitoring system will answer the questions regarding their health via the internet from their home computer. If the subject's spirometry falls by greater than 10% from baseline or the CF respiratory symptoms change in 3 or more of the 8 respiratory symptoms captured by the telemonitor questionnaire, the subject will be called by the research staff and clinically evaluated by the study PIs within three days. The usual care subjects will continue with their routine care at the University of Washington CF Clinic.
