Advice

The HAPS should not be used in isolation to suggest that a patient will have a “harmless” course of pancreatitis, but may be an additional useful piece of data in otherwise low-risk patients.

Management

We are not aware of algorithms incorporating the HAPS.

Critical Actions

The HAPS is not designed to identify patients with high risk of pancreatitis, only those with low risk.
