感染性腹泻患者的调查经常需要粪便细菌病原体培养，但文献报道这种诊断试验的得率很低。确定粪便培养阳性的临床预测因素将有助于医生确定大便要求的必要性。本研究以香港一家急诊科为背景，对粪便培养阳性的成人患者和培养阴性的成人患者的临床表现特征进行了回顾性研究。我们比较了12个月期间连续130例粪便培养阳性的病例与同期随机抽样的524例连续粪便培养阴性病例中的119例对照病例。在多变量分析中，与粪便培养阳性相关的独立变量有：发病月份(夏季)、发热、腹痛持续时间和是否需要静脉输液治疗。无论是血性腹泻还是持续性腹泻都与粪便培养阳性无关。(C)2002年爱思唯尔科学公司。
Stool cultures for bacterial pathogens are often requested for investigation of patients with infectious diarrhea, but the literature reports low yield for this diagnostic test. The identification of clinical predictors of positive stool culture will help the physician in determining the necessity for stool requests. A retrospective study was performed in the setting of an Emergency Department (ED) in Hong Kong, to compare presenting features of adult patients with positive stool culture against those with negative culture. We compared 130 consecutive cases with positive stool culture, over a 12-month period, against 119 control cases obtained from a random sampling of 524 consecutive negative cases over the same period. In multivariate analysis, the independent variables found to be associated with positive stool culture were: the month of presentation (summer season), fever, duration of abdominal pain, and requirement of IV fluid therapy. Neither bloody diarrhea nor persistent diarrhea was associated with positive stool culture. (C) 2002 Elsevier Science Inc.
