Abstract
The purpose of this study was to evaluate the service to patients with appendicitis among three
schemes: Universal coverage scheme: UCS, Social security scheme: SSS and Civil servant medical benefit
scheme: CSMBS. 401,322 records of in-patients during 2005 -2008 were utilized, and analyzed by descriptive
statistic and logistic regression analysis.
Acute appendicitis admission rate per 100,000 population between 2005 and 2008 showed that it was
highest in CSMBS, 215.4-300.4, while SSS was between 141.6-203.8 and UCS was between 165.9 and 177.6.
The trend was increasing in UCS and SSS, while it was decreasing in CSMBS. Proportion of ruptured
appendicitis to total appendicitis indicated that those of SSS, UCS and CSMBS were 12.5%, 18.2%, and
18.5% respectively. In addition, ruptured appendicitis probability were significantly different among three
schemes (P<0.00) which those of SSS and CSMBS had a lower chance compared to those of UCS, 1.48 and
1.38 times respectively. However, the trends of ruptured appendicitis to total appendicitis patients of all
schemes decreased. The trend of mortality rate of appendicitis patient in each scheme had not change
dramatically. It was highest in CSMBS and UCS (0.2%), while those of SSS were 0.02% respectively. With
regard to percentage of acute appendicitis patient receiving appendectomy, it was found that SSS patients
had a highest percentage, 89.4% while CSMBS and UCS were 83.5% and 83.0% respectively. However, the
trend of those having acute appendicitis receiving appendectomy in all schemes had been increasing.
