KANDID, an EMG decision support system, showed moderate diagnostic agreement (61%) with clinicians in a multicenter trial. Success hinges on local customization for end-user adaptation.

Area of Science:

  • Clinical Neurophysiology
  • Medical Informatics

Background:

  • Electromyography (EMG) examinations require expert interpretation.
  • Decision support systems (DSS) can aid clinical neurophysiologists.
  • KANDID is an advanced DSS for EMG procedures.

Purpose of the Study:

  • To evaluate the agreement between KANDID's diagnostic statements and clinical neurophysiologists' assessments.
  • To assess KANDID's usability in routine clinical EMG practice across multiple European centers.

Main Methods:

  • Prospective European multicenter field trial involving 159 patient EMG examinations.
  • Nine clinical neurophysiologists from seven EMG laboratories participated.
  • Agreement levels for electrophysiological states and diagnoses were measured.

Main Results:

  • KANDID's reasoning was understandable in 80-90% of cases.
  • Average agreement for muscle/nerve electrophysiological states was 81%.
  • Average diagnostic agreement with KANDID was 61%, with significant inter-center variation.

Conclusions:

  • KANDID can be successfully deployed in clinical settings with local customization.
  • End-user customization via editors is crucial for successful system transfer and application.
  • Inter-examiner and inter-center variations highlight the need for adaptable systems.
