Structured Education Improves Radiographic Detection and Referral in Charcot Foot: A Quasi-experimental Study

Charcot foot, characterized by progressive osseous and articular destruction, necessitates early diagnosis and a multidisciplinary approach to prevent severe complications. This study assessed the efficacy of an educational intervention in improving radiographic detection and referral for Charcot foot among health care professionals.

Thirty health care professionals, including foot and ankle surgeons (FAs), orthopaedic/trauma specialists (OTs), and family physicians (FDs), participated in this quasi-experimental, pre-post study. Participants completed a baseline assessment and received an educational intervention (face-to-face/webinar or self-directed PDF), followed by a reassessment. Primary outcomes included changes in diagnostic and referral accuracy, evaluated through score improvements and Fleiss κ for interobserver agreement. Reliability in the Meary angle measurement was also assessed.

FA specialists demonstrated consistently high baseline scores. Following the intervention, OT and FD groups exhibited significant improvements in both diagnostic and referral scores. Fleiss κ increased from 0.463 to 0.700 for OT diagnosis, and from 0.439 to 0.723 for referral. Fleiss κ values for FD improved from 0.352 to 0.546 for diagnosis and from 0.071 to 0.608 for referral. Face-to-face/webinar training outperformed the PDF format, yielding higher scores and agreement rates. Interobserver reliability for the Meary angle was excellent (intraclass correlation coefficient = 0.988).

Structured educational interventions significantly enhanced clinicians' ability to diagnose and appropriately refer patients with Charcot foot. Face-to-face instruction proved more effective than self-directed formats.
