() is a leading cause of infectious diarrhoea in hospitals. Sending faecal samples for testing expedites diagnosis and appropriate treatment. Clinical suspicion of based on patient history, signs and symptoms is the basis for sampling. Sending faecal samples from patients with diarrhoea 'just in case' the patient has may be an indication of poor clinical management.
To evaluate the effectiveness of an intervention by an Infection Prevention and Control Team (IPCT) in reducing inappropriate faecal samples sent for testing.
An audit of numbers of faecal samples sent before and after a decision-making algorithm was introduced. The number of samples received in the laboratory was retrospectively counted for 12-week periods before and after an algorithm was introduced.
There was a statistically significant reduction in the mean number of faecal samples sent post the algorithm. Results were compared to a similar intervention carried out in 2009 in which the same message was delivered by a memorandum. In 2009 the memorandum had no effect on the overall number of weekly samples being sent.
An algorithm intervention had an effect on the number of faecal samples being sent for testing and thus contributed to the effective use of the laboratory service.
（）是医院感染性腹泻的主要病因。送检粪便样本进行检测可加快诊断和适当治疗。根据患者病史、体征和症状进行临床怀疑是采样的基础。对腹泻患者“以防万一”患者患有（）而送检粪便样本可能表明临床管理不佳。
评估感染预防与控制团队（IPCT）的一项干预措施在减少送检用于（）检测的不适当粪便样本方面的有效性。
对引入决策算法前后送检的粪便样本数量进行审核。在引入算法前后，回顾性统计实验室收到的样本数量，统计周期均为12周。
引入算法后送检的粪便样本平均数量有统计学意义的减少。将结果与2009年进行的类似干预进行比较，当时通过一份备忘录传达了相同的信息。2009年，该备忘录对每周送检样本的总数没有影响。
算法干预对送检用于（）检测的粪便样本数量有影响，从而有助于实验室服务的有效利用。
