For hospitals and collaborators
Participate in SnapChole
Participation is coordinated through hospital teams conducting a local clinical audit. There is no patient sign-up form on this site.
How a centre gets started
The participating service leads local case identification, governance review, and the accuracy of its SnapChole audit records.
Review the current protocol
Use the current dated specification as the single study description published on this site.
Complete local review
Your institution determines the applicable audit, ethics, privacy, and data-governance requirements before activity begins.
Onboard the team
Begin the 90-day consecutive case review only after local requirements and the approved audit materials are confirmed.

Local case review, with aggregate reporting
The current SnapChole specification describes adults with TG18 Grade II or III acute calculous cholecystitis, a consecutive 90-day local audit period, and no study-specific patient contact. Patient-level records remain at each service and only anonymous aggregate data are shared centrally.
