Key performance measure	Rate of complications for diagnostic and therapeutic DAE procedures
Description	Percentage of patients undergoing diagnostic and therapeutic DAE who experience a significant complication Complication rate (overall, including perforation, bleeding, and pancreatitis) resulting from diagnostic and therapeutic DAE should not exceed 1% and 5%, respectively, in an unselected population
Domain	Complications
Category	Outcome/Process
Rationale	Monitoring for complications is essential to ensure the safety of the procedure
Construct	Denominator: Patients undergoing DAE Numerator: Patients in the denominator experiencing a complication (perforation, bleeding, or pancreatitis) Exclusions: None Calculation: Proportion (%) Level of analysis: Service and individual level Frequency: Yearly and/or for a sample of 100 DAEs
Standards	Minimum standard: < 5% Target standard: < 5% If the minimum standard is not reached, analysis of the factors influencing complication rate (including assessment of operator numbers, operator experience, case complexity, presence of previous small-bowel surgery, and underlying pathology) should be performed on an individual and service level After evaluation and adjustment, close monitoring should be performed with a further audit within 12 months
Consensus agreement	100%
PICO numbers	16, 18 (see Supporting information, DAE file)
Evidence grading	Moderate-quality evidence
