Pattern/seizure burden and index

Measures of the duration or frequency-weighted duration of a pattern over an explicitly defined reporting interval.

Criteria & assessment

  • Daily burden: total pattern or seizure duration per 24 hours; hourly and maximal hourly burdens also reportable.
  • Daily pattern index: daily burden multiplied by mean frequency; retain units (Hz-hours or Hz-minutes).

  • Union overlapping intervals for occupied time; declare missing-data denominator policy in P3 rather than invent it as ACNS rule.
