Incidence of Early Postoperative Complications in Upper Extremity Orthopedic Surgery and Reliability of the Modified Clavien-Dindo-Sink Classification: A Real-World Study.

ABSTRACT:

Background

Upper limb orthopedic surgery has no standardized complication classification system. The adaptations in the Clavien-Dindo classification system have only been validated through the creation of scenarios. We hypothesized that the modified Clavien-Dindo-Sink (CDS) classification of hand and upper extremity surgery complications has good intraobserver and interobserver reliability in real-world scenarios. This study assessed the accuracy of the modified CDS classification in real-world scenarios and the absolute incidence of 30-day complications.

Methods

The sample size calculation was based on the modified CDS classification. A kappa value of 0.84, accompanied by a 95% confidence interval (CI) of 0.1 and involving 6 observers, indicated the inclusion of 111 events.
