Improved outcomes in cystic fibrosis using modified <u>R</u>e-<u>E</u>ducation of <u>A</u>irway <u>C</u>learance <u>T</u>echnique (REACT) programme.

Abstract

Cystic fibrosis (CF) is known to reduce lung function as measured by per cent predicted for the forced expiratory volume in the first second (ppFEV₁) over time. Our paediatric CF programme demonstrated significant gaps in benchmarked ppFEV₁ predicted compared with the national median. Our objective was to assess whether the implementation of a modified <u>R</u>e-<u>E</u>ducation of <u>A</u>irway <u>C</u>learance <u>T</u>echniques (REACT) programme could lead to an improvement in lung function as measured by ppFEV₁. This 2-year prospective quality improvement study at Lurie Children's CF Center for children aged >6 years used improvement methodology to implement a modified REACT programme. Outcome measures were assessed for our entire programme via the CF Foundation Patient Registry (CFFPR) and statistical process control. Comparisons were also made before and after REACT for outcome measures. By the end of implementation, monthly participation rate achieved 100%. Using CFFPR data and SPC, median ppFEV₁ increased by 3.9%, whereas only body mass index (BMI) as a secondary outcome increased. Comparison of pre and post REACT showed improvements in average ppFEV₁ (95% vs 96%, p<0.0001), FEF_25%-75% (82% vs 83%, p=0.0590), rate of ppFEV1 decline (+2% vs -4%, p=0.0262) and BMI percentile (57% vs 60%, p<0.0001). Implementation of a modified REACT at Lurie Children's paediatric CF programme led to an increase in ppFEV₁, FEF_25%-75% and BMI percentile.
