Intraoperative adverse events in gynaecological surgery are more common than reported. Not because surgeons are hiding them, but because until recently there was no standardised way to classify them.
CiASE, the Classification of Intraoperative Adverse Surgical Events, changes that. Developed by colleagues at the Queensland Centre for Gynaecological Cancer Research, CiASE provides a validated grading system from Grade 0 (no adverse event) through to Grade 4 (intraoperative or perioperative death), with 95.2% accuracy and near-perfect inter-rater reliability across 25 surgeons.
It distinguishes between adverse events that have minimal impact on recovery and those that require readmission, reoperation, or result in ongoing disability. It gives surgeons a shared, precise language for what happens in the operating room.
SurgicalPerformance supports CiASE classification directly within the platform, so your intraoperative adverse events are captured, graded, and tracked alongside your broader outcomes data.
Because you cannot improve what you cannot clearly define.
