2.5 Assessment of real-time MBW quality control in secondary
centre in Zurich
To validate our findings, we implemented real-time MBW quality control
in a centre (Zurich, Switzerland) with less experience in MBW
methodology. We first assessed MBW measurements from a random subset of
34 clinical visits from pediatric patients with CF attending their
routine care in Zurich, Switzerland. The MBW operators were then
instructed on how to use the quality control matrix and given access to
the supplementary teaching material (see online supplemental). Mandatory
real-time MBW quality control and reporting of test acceptability was
implemented for all measurements. We then retrospectively assessed test
acceptability and agreement between the operator and reviewer in a
random subset of 30 MBW measurements.
