Detailed Description

The aim of this project is to implement a clinical tool utilizing predictors of mortality for patients with Cystic Fibrosis (CF) on the waiting list to identify candidates that should present for urgent medical care and, if appropriate, will prompt clinicians to update a candidate's lung allocation score (LAS), the score used to prioritize lung transplant candidates for transplant by medical urgency, and avoid undetected decline. The clinical tool consists of home spirometry measures and patient reported outcomes that is completed weekly on a mobile application device used clinically to track spirometry.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Clinical Tool (Mobile Spirometry and Survey)
All subjects enrolled will be placed into the clinical tool arm. The clinical tool is comprised of a mobile application based assessment of home spirometry and a survey measuring patient reported outcomes.
Other: Clinical Tool (Mobile Spirometry and Survey)
The clinical tool is a combination of home spirometry measurements and a patient survey measuring patient reported outcomes including the Cystic Fibrosis Respiratory Symptom Diary (CFRSD) and Chronic Respiratory Infection Symptom Score (CRISS©), with permission from the Seattle Quality of Life Group.
