다국어 초록 (Multilingual Abstract)

This study was an analysis for several factors affecting the hospital stay in the patients of acute appendicitis.
From Jan. to Dec. 1983, 166 patients, who underwent appendectomy under the impression of acute appendicitis and were confirmed appendicitis postoperatively in Chonbuk National University Hospital, have been investigated to the relationship between the hospital stay and their personal charactersitics including medico-social factors.
The results were as follows ;
1. In the age and sex distributions, the proportions of age group 10-19 years(22.9%) and 20-29 years(25.3%) were higher than other age groups(p<0.05), and the sex ratio was 1.1:1(male;87 cases, female ; casas) which difference was not significant(p>0.05).
2. Average hospital stay was 8.3±5.0 days that were not affected by sex, medical insurance, andeducational levels(p>0.05). In the simple correlation analysis, the main factors than affect hospital stay in the patients of acute appendicitis were postoperative diagnosis(r=＋0.672), type of appendectomy(r=＋0.640), interval between the symptom onset and admission(r=＋0.412), and age of patient(r=＋0.260).
3. In the multiple regression analysis, the prediction equation of the duration of hospital stay was;
Y=－0.079＋0.093×1＋0.076×2－0.003×3＋0.288×4＋0.670×5＋0.521×6 where X_1=age, X_2=resident area, X_3=education, X_4=interval between the symptom onset and admission, X_5=type of appendectomy, and, X_6=postoperative diagnosis.
The overall accuracy of the prediction equation was reflected by R-square=55%(F-ratio 6,159=32.31, p<0.01).
