Using the SWEET tool to predict how long an ERCP will take

Prospective Validation of the SWEET Tool for Pre-diction of Preintervention ERCP Procedure Time.

Observational Universitair Ziekenhuis Brussel · NCT07259395

This project will test whether the SWEET tool can accurately predict how long an ERCP will take for adult patients having first-time or repeat ERCPs.

What this trial studies

This prospective observational validation will compare preprocedure SWEET tool estimates to the actual measured durations of ERCPs performed at UZ Brussel. The SWEET tool was derived from a large Swedish registry and uses ten patient- and procedure-related variables to estimate procedure time; here it will be applied to adults undergoing intraductal ERCP, including procedures performed by fellows under supervision. ERCPs in altered anatomy and those combined with therapeutic EUS are excluded from this validation. The primary outcome is the accuracy of the predicted times compared with observed times, reported with standard metrics such as RMSE.

Who should consider this trial

Good fit: Adults older than 18 scheduled for intraductal ERCP at UZ Brussel, including both first-time and repeat procedures and cases performed by fellows under supervision.

Not a fit: Patients with surgically altered anatomy or ERCPs combined with therapeutic EUS interventions are excluded and would not benefit from this validation.

Why it matters

Potential benefit: If successful, the SWEET tool could help clinics schedule ERCPs more accurately, reduce delays and overtime, and improve patient flow.

How similar studies have performed: A large retrospective derivation using 74,248 ERCPs in the Swedish GallRiks registry produced the SWEET tool with promising predictive performance, but prospective validation has been limited.
