Malfunction reports run above the device-type norm

Mass Spectrometry carries 98.8% MALFUNCTION-coded reports, 34.0pp above the 1,000-device-type mean, the widest gap of its three event codes. Codes are report labels, not adjudicated causation.

  • DEATH 0.0% corpus 1.5% · below corpus mean (-1.5 pp)
  • INJ 1.2% corpus 30.3% · below corpus mean (-29.1 pp)
  • MALF 98.8% corpus 64.8% · above corpus mean (+34.0 pp)

Lead product-problem code Incorrect, Inadequate or Imprecise Result or Readings is 71% of coded problems · Top event location is 58% of location-tagged rows .
