Abstract

Introduction: National data has the potential to advance future research and drive quality improvements for patients with major lower-extremity amputations (MLEA). This study aimed to evaluate the implementation of the Danish Amputation Database (DanAmp) by investigating data completeness and validity.

Methods: Demographic, surgical and post-surgery data were collected during hospital admission. After implementation at three departments, completeness and validity were evaluated from 1 February to 1 June 2024. Completeness was evaluated by comparing the number of surgical procedures in the hospital's electronic system with registrations in DanAmp. Data validity was evaluated by an audit of up to 15 consecutive patient records per department. The percentage agreement was calculated (agreement (n)/total possible numbers (N)). Variables with an agreement exceeding 90% were considered satisfactory.

Results: A total of 68 procedures were registered in DanAmp across the three departments, and 71 procedures were registered in the hospital's electronic system, corresponding to 96% completeness for all types of procedures. A total of 43 patient records were audited, revealing that 29 of 35 variables had a satisfactory validity exceeding 90% agreement.

Conclusions: This study demonstrated a high completeness and satisfactory validity of data from three orthopaedic departments, underscoring DanAmp's potential in driving research and quality improvements for MLEA.

Funding: The project is funded by the Region Zealand and Region of Southern Denmark Research Fund (2022) and the Independent Research Fund Denmark (DFF), grant ID: 10.46540/3165-00053B (2023).
