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

Abstract

Rationale: Cystic fibrosis (CF) centers transitioned to telemedicine during the spring 2020 peak of the coronavirus disease (COVID-19) pandemic. Objectives: We hypothesized that people with CF (pwCF) with more severe disease would be more likely to be seen in-person. Methods: We used paired t tests to compare within-subject changes in body mass index (BMI) and percentage predicted forced expiratory volume in one second (FEV1) 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. Results: Overall, the proportion of clinical encounters that were in-person clinic visits decreased from 91% in 2019 to a low of 9% in April 2020. Among pwCF seen after March 15 in both 2019 and 2020, the mean (95% confidence interval [CI]) FEV1 percentage predicted was 1.3% (0.1-2.4) predicted higher in 2020 for children 6 to <12 years of age, and 7.5% (7.1-7.9) predicted higher in 2020 among pwCF ⩾12 years of age eligible for the highly effective CF transmembrane conductance regulator modulator, elexacaftor-tezacaftor-ivacaftor (ETI). There was no difference in FEV1 percentage predicted for pwCF ⩾12 years of age who were not eligible for ETI. Similarly, the mean (95% CI) BMI was 2.4 (2.0-2.8) percentile higher in 2020 for children 6 to <12 years of age and 5.2 (4.8-5.7) percentile higher in 2020 among children 12 to <18 years of age eligible for ETI. Mean (95% CI) BMI was 1.2 (1.2-1.3) (kg/m2) higher for pwCF ⩾18 years of age eligible for ETI, and 0.2 (0.1-0.3) (kg/m2) higher for pwCF ⩾18 years of age not eligible for ETI. The proportion of in-person clinic visits where any PEx was present was lower in 2020 compared with 2019, 25% compared with 38%, RR 0.82 (0.79-0.86). Conclusions: The care of pwCF was substantially changed during the spring 2020 peak of the COVID-19 pandemic. Among pwCF seen in-person in both 2019 and 2020 after the spring peak of the COVID-19 pandemic, lung function and BMI were higher in 2020 for children 6 to <12 years of age and pwCF eligible for ETI.
