Lessons from the on-site quality audit of data transmitted to the French cystic fibrosis registry

Background The French Cystic FibrosisRegistry takes a census of the population of patients and records their annual data transmitted by Cystic FibrosisCenters (CFCs). Quality of patient data has been a focus in the past years, with the implementation of automated controls before data integration. The objective was to assess, at the 14 CFCs trained in the quality improvement named Hospital Program to Improve Outcomes and Expertise in Cystic Fibrosis(PHARE-M), the quality of the 2012 and 2013 data transmitted to the French Registry with respect to the rules established to obtain forced expiratory volume in 1 second (FEV1%) and anthropometric data.
