Computer-aided diagnosis consists of using retrospective data of clinical features of patients with appendicitis and other causes of abdominal pain and then prospectively assessing the risk of appendicitis. Computer-aided diagnosis can achieve a sensitivity greater than 90% while reducing rates of perforation and negative laparotomy by as much as 50%.

However, the principle disadvantages to this method are that each institution must generate its own database to reflect characteristics of its local population, and specialized equipment and significant initiation time are required. In addition, computer-aided diagnosis is not widely available in US EDs.
