Changes in Care during the COVID-19 Pandemic for People with Cystic Fibrosis.

Cystic fibrosis (CF) centers transitioned to telemedicine during the spring 2020 peak of the coronavirus disease (COVID-19) pandemic. We hypothesized that people with CF (pwCF) with more severe disease would be more likely to be seen in-person. We used paired tests to compare within-subject changes in body mass index (BMI) and percentage predicted forced expiratory volume in one second (FEV) and calculated relative risk (RR) to compare pulmonary exacerbations (PEx) between pwCF enrolled in the CF Foundation Patient Registry with at least one in-person clinic visit after March 15 in both 2019 and 2020.
