Use of the Alvarado scoring system was assessed prospectively in a consecutive series of 215 patients with suspected appendicitis over a 12 month period at the University Hospital of Wales, Cardiff. In comparison the high negative appendicectomy rate during the year prior to the study was reduced considerably with the scoring system without increasing morbidity or mortality.
在威尔士大学医院(位于加的夫),对连续215例疑似阑尾炎患者在12个月期间前瞻性地评估了阿尔瓦拉多评分系统的使用情况。相比之下,在研究前一年较高的阴性阑尾切除率在使用评分系统后大幅降低,且未增加发病率或死亡率。
