J Surg Pak Jan ;16(3):103-8.

Objective To compare the efficacy of Alvarado and Teicher scores in the diagnosis of acute appendicitis, using postoperative histopathology as gold standard. Study design Comparative, cross sectional study. Place & Duration of study Department of surgery, Combined Military Hospital Rawalpindi, from 22nd June 2006 to 26th February 2007. Methodology Hundred cases of clinically diagnosed/suspected of acute appendicitis were included in the study by convenience (non-probability) sampling. Selected patients were graded according to Alvarado and Teicher scores, and underwent appendicectomy. All appendicectomy specimens were sent for histopathology reporting. A 2 x 2 table was used to determine sensitivity, specificity, positive and negative predictive values and diagnostic efficacy for both the scoring systems. Results Using Alvarado and Teicher scores, a sensitivity of 95% and 89.55%, specificity of 69.69% and 66.66%, positive predictive value of 86.48% and 85.71%, negative predictive value of 88.46% and 76.66%, negative appendicectomy rate of 13.5% and 15.49% and diagnostic efficacy of 87% and 83% were found, respectively. Conclusion Alvarado score has better diagnostic accuracy as compared to Teicher score in the diagnosis of acute appendicitis.
