Abstract
Appendicitis is the most common abdominal surgical emergency. Diagnosis of acute appendicitis is essentially clinical in the form of acute right iliac fossa pain which starts periumbilical then shifts to the McBurney point, becomes more sharper pain which is localized and aggravated by movement or cough, anorexia, nausea and vomiting but always precedes the pain, constipation and may be present with fever, tachycardia, rigidity if perforation occurs, high leukocytic count and shift to left.Symptoms of acute appendicitis overlapping with a number of other conditions making diagnosis a great challenge, particularly at an early stage of presentation, patients may be suitably triaged into alternative management strategies; reassurance, pursuit of an alternative diagnosis or observation, admisdsion to hospital and if admitted to hospital, appropriate imaging may be required prior to proceeding to appendectomy.
Clinical Prediction Rules (CPR) quantify the diagnosis of a target disorder based on findings of key symptoms, signs and available diagnostic tests, which helps in management recommendation, CPR have the potential to reduce diagnostic error, increase quality and enhance appropriate patient care.
