Acute Appendicitis: The Influence of C-reactive Protein and Leucocytes on Clinical Decision-making

A prospective observational cohort study including patients (≥15 years of age) admitted on suspicion of AA. The surgeons were instructed to perform their physical examination and register whether they found the patient more or less than 50% likely to have AA. Thereafter, the surgeons had to assess the blood results and reevaluate their diagnosis. The surgeon's diagnosis before and after was compared to the final diagnosis defined by surgical findings or follow up. Gold standard was any degree of appendicitis on histology.
