To assess the effectiveness of predetermined investigation criteria for the examination of faecal samples from inpatients, cultured stool specimens were prospectively examined for Salmonella spp, Shigella spp, Campylobacter spp and Clostridium difficile, and screened microscopically for intestinal parasites. Out of a total of 505 specimens, 421 (83%) fulfilled the criteria for examination for C difficile, 254 (50%) for Salmonella spp, Shigella spp, and Campylobacter spp, and 87 (17%) for intestinal parasites. Isolation rates for these organisms in those groups of patients where examination was indicated were 22.5% for C difficile and 9.1% for Salmonella spp, Shigella spp, and Campylobacter spp; the detection rate for parasites was 3.5%. In those patients where the criteria did not suggest investigation, the isolation or detection rates were 3.6% for C difficile, 0% for Salmonella spp, Shigella spp, and Campylobacter spp, and 1.7% for intestinal parasites, suggesting that the use of predetermined investigation criteria was effective.
为评估预定的检查标准对住院患者粪便样本检查的有效性，前瞻性地对培养的粪便标本进行了沙门氏菌属、志贺氏菌属、弯曲杆菌属和艰难梭菌的检测，并进行显微镜检查以筛查肠道寄生虫。在总共505份标本中，421份（83%）符合艰难梭菌检查标准，254份（50%）符合沙门氏菌属、志贺氏菌属和弯曲杆菌属检查标准，87份（17%）符合肠道寄生虫检查标准。在建议进行检查的患者组中，这些病原体的分离率为艰难梭菌22.5%，沙门氏菌属、志贺氏菌属和弯曲杆菌属9.1%；寄生虫检测率为3.5%。在标准未建议进行检查的患者中，艰难梭菌的分离或检测率为3.6%，沙门氏菌属、志贺氏菌属和弯曲杆菌属为0%，肠道寄生虫为1.7%，这表明使用预定的检查标准是有效的。
