Adult patients with Cystic Fibrosis who are seen at the specialty CF clinic at University of Virginia will be given an option to utilize telemedicine instead of in-person visits for standard clinic visits. Health information from standard of care visits including FEV1, exacerbations, leading to oral or intravenous antibiotics, laboratory results, hospitalization records, and responses to health questionnaires will be recorded for research purposes. Data collected for the research study will be compared to baseline and previous years to determine if there are any deleterious effects for those who transition to telemedicine clinic visits.

Inclusion Criteria:

• Adult patients (18-year-old and older) with CF seen in the UVA adult CF clinic who agree to participate in the study.

Exclusion Criteria:

• Patients who cannot consent to the research study. In addition, prisoners will not be included.

Adult CF patients 18 yo and older.
