The randomization plan will include constrained randomization using the permuted blocks method. The research team member will open the envelope that contains the randomized treatment and the Admission Order Sheet that details the orders that need to be placed on admission. The research team member will communicate this information to the ED or inpatient attending physician or staff member overseeing the patient's care at the time of enrollment. All clinical treatments described in this protocol, including labs orders, are the current standard of care for acute pancreatitis diagnosis. The purpose of the Admission Order Sheet is to standardize the timeline of the lab work at admission, at 24 hours and 48 hours after admission, not to request any additional lab work for the purposes of the study.
