Christian and Christian developed a simple scoring system for evaluating patients for acute appendicitis. The purpose of the score was to reduce the number of negative appendectomies. The authors are from St. Martha's Hospital in Bangalore, India.
Patients: ranged from 7 to 56 years of age
Parameters:
(1) abdominal pain
(2) vomiting
(3) right lower quadrant tenderness
(4) low grade fever
(5) polymorphonuclear (PMN) leukocytosis

where:
• Pain limited to the right iliac fossa alone was not considered abdominal pain.
total score =
= SUM(points for all 5 parameters)
Interpretation:
• minimum score: 0
• maximum score: 5

not admitted for observation |
Performance:
• The negative appendectomy rate was much lower in patients treated according to this protocol.
• There were no cases of acute appendicitis in the patients not admitted, but the numbers were relatively small (12 patients).
