Patients with right iliac fossa pain present a diagnostic challenge to emergency room doctors when equivocal signs are present.
To evaluate Alvarado score as an admission criterion in patients with suspected diagnosis of acute appendicitis.
This was a prospective study of 100 consecutive patients who presented to the an emergency department with right iliac fossa pain and suspected diagnosis of acute appendicitis between January 2004 and December 2004. They were assessed usingAlvarado score. Main outcome measures in relation to these scores were, patient's admission, patient's discharge, and whether patient had appendicitis or not.
The range of scores was 1-10. Seventy-four patients were admitted while 26 were discharged. Thirty-four patients with confirmed diagnosis of acute appendicitis had scores ranging from 5-10. No patient with score less than 5 had appendicitis. The sensitivity and negative predictive value reached 100% at scores below five, while specificity and positive predictive value reached 100% at the score of 10.
The Alvarado score can be used as an objective criterion in selecting for admission patients with suspected diagnosis of acute appendicitis. Patients with scores of 4 and below do not require admission since they turn out not to have acute appendicitis.
当出现不明确的体征时，右下腹疼痛的患者给急诊医生带来了诊断挑战。
评估阿尔瓦拉多评分作为疑似急性阑尾炎诊断患者入院标准的价值。
这是一项前瞻性研究，对2004年1月至2004年12月期间连续100例因右下腹疼痛并疑似急性阑尾炎而就诊于急诊科的患者进行研究。使用阿尔瓦拉多评分对他们进行评估。与这些评分相关的主要结局指标为患者入院情况、出院情况以及患者是否患有阑尾炎。
评分范围为1至10分。74例患者入院，26例出院。确诊为急性阑尾炎的34例患者评分在5至10分之间。评分低于5分的患者均无阑尾炎。评分低于5分时，敏感性和阴性预测值达到100%，而评分达到10分时，特异性和阳性预测值达到100%。
阿尔瓦拉多评分可作为疑似急性阑尾炎诊断患者入院选择的客观标准。评分4分及以下的患者无需入院，因为他们最终未患急性阑尾炎。
