Background: Although many clinical prediction rules (CPRs) for appendicitis exist, none have been developed for a New Zealand population presenting with right iliac fossa (RIF) pain. The aim of this study was to derive and validate an appendicitis CPR for our population.
Method: This is a retrospective review of all patients from December 2010 to February 2012 of at least 15 years of age presenting to the general surgery service with RIF pain.
