A cost analysis based on changes in patient care was used to evaluate the utility of abdominal ultrasonography in both the clinical management of patients clinically suspected of having acute appendicitis and in reducing expenditure of hospital resources. Among the 200 patients suspected of having acute appendicitis, 57 actually had acute appendicitis. Interpretation of appendiceal ultrasonographic results was 98.5% accurate. The ultrasonographic result led to changes in the treatment of 103 patients. Moreover, ultrasonography led to the prevention of unnecessary appendectomy in 25 patients, providing a savings to the hospital of about Yen 8,013,450 ($65,150), and prevented unnecessary hospital admission for 78 patient‐days, thus saving the hospital approximately Yen 1,199,250 ($9750). The cost of performing the 200 ultrasonographic examinations was about Yen 1,096,176 ($8912), and thus the overall savings to the hospital was approximately Yen 40,590 ($330) per patient. Ultrasonography performed in patients with suspected acute appendicitis improves patient diagnostic accuracy, thus leading to more appropriate selection of patient treatment and reduced hospital expenditure.
