Abstract

Introduction: At our centre, infant lung function (ILF) is routinely performed in children with cystic fibrosis (CF). Research question: do ILF results affect clinical management?

Methods: Mono-centre retrospective cohort analysis of subjects with CF born between 2014 and 2018. Z-scores for SF₆ Lung Clearance Index (zLCI), plethysmographic FRC (zFRC_pleth) and zFEV0.₅ were derived. The closest clinical encounter following each ILF data point was reviewed to evaluate whether there were changes in clinical management and why.

Results: Following 95 ILF tests there were 10 changes in management, but only one of these was for abnormal ILF results alone. In the other 9 cases there were also increased symptoms and/or abnormal microbiology. See table for full results

Conclusion: This analysis did not demonstrate change in clinical management following ILF results alone. Prospective studies involving weighting of different factors are required to assess the utility of ILF.
