Maintenance
Maintenance measures the continued use of the program over time. For this study, because it was funded by clinical trial grant monies, we measured maintenance on two levels. First, individual level maintenance of exercise by joining a gym or by continuing in a standard PR program. This does not reflect the value of TelePR directly but measures motivation that TelePR provided to exercise and the benefits of exercise. Second, we describe inquiries from health systems and pulmonary organizations to continue the TelePR programs, and the logistical and financial considerations that were discussed.
