OBJECTIVE To determine the validity of the superstition that utterance of the word "quiet" in a clinical setting increases workload. DESIGN Prospective randomised controlled non-inferiority study. SETTING Microbiology department of a large teaching hospital in Lancashire, UK. PARTICIPANTS Two members of the medical microbiology team carried out the duty work on any given week day and an on-call team member on any weekend day. 29 days were assigned in which staff were to say "Today will be a quiet day" and 32 days were assigned in which staff were to refrain from saying the word "quiet" in any context. INTERVENTIONS Each day was randomly allocated to either saying "Today will be a quiet day" (intervention group) or refraining from saying the word "quiet" (control group) in any context. MAIN OUTCOME MEASURES The primary outcome was mean overall workload: a composite of number of clinically related telephone calls, clinically significant results, or validated results processed by the duty medical microbiology team during a 24 hour period referred to collectively as "clinical episodes." A difference of 30 clinical episodes was considered as the margin of non-inferiority. Secondary outcomes included the individual components of the primary outcome. RESULTS Workload was measured each day over a 61 day period (1 May to 30 June 2019). A mean 139.0 clinical episodes occurred on control days compared with 144.9 on days when the experimental intervention was uttered, a difference of 5.9 (95% confidence interval-12.9 to 24.7). The upper bound was less than the specified margin of 30, providing evidence for non-inferiority. No evidence of a difference in workload was found between interventions with any of the four components, whether considering unadjusted or adjusted analyses, or looking at the subgroups of week days or weekends. CONCLUSIONS The study findings refute the long held superstition that utterance of the word "quiet" impacts on clinical workload, and therefore it should not be avoided. In the era of considerable staff shortages and increased work related stress, doctors should look to other methods to increase resilience and protect their wellbeing and mental health.

Q发烧-避免使用“安静”一词作为应对机制的迷信：随机对照非劣效性试验。

目的确定迷信的有效性，即在临床环境中说“安静”一词会增加工作量。设计前瞻性随机对照非劣效性研究。设在英国兰开夏郡的一家大型教学医院的微生物科。参加者医学微生物学团队的两名成员在任何给定的工作日进行值班工作，并在周末的任何时候进行值班。分配了29天，其中工作人员说“今天将是安静的一天”，分配了32天，其中工作人员在任何情况下都不要说“安静”。干预每天随机分配给“说今天将是安静的一天”（干预组），或者在任何情况下都不要说“安静”（对照组）。主要观察指标主要结果是平均总体工作量：临床相关的电话数量，临床上显着的结果或值班医疗微生物学团队在24小时内处理的经过验证的结果的总和，统称为“临床发作”。30次临床发作之间的差异被认为是非自卑的余地。次要结果包括主要结果的各个组成部分。结果在61天的时间段内（2019年5月1日至6月30日）每天测量工作量。对照日平均发生139.0次临床发作，而进行实验性干预的当天平均发生144.9次，相差5.9（95％置信区间12.9至24.7）。上限小于指定的边际值30，为非自卑感提供了证据。无论是考虑未经调整的分析还是经过调整的分析，还是查看工作日或周末的子组，都没有发现有四个组成部分的干预措施之间工作量有所不同的证据。结论研究发现驳斥了长期存在的迷信，即“安静”一词会影响临床工作量，因此不应避免。在人员严重短缺和与工作相关的压力日益增加的时代，医生应寻求其他方法来增强适应力并保护其健康和心理健康。试验注册兰开夏郡教学医院NHS基金会信托基金的研究部门SE-259。或查看工作日或周末的子组。结论研究发现驳斥了长期存在的迷信，即“安静”一词会影响临床工作量，因此不应避免。在人员严重短缺和与工作相关的压力日益增加的时代，医生应寻求其他方法来增强适应力并保护他们的健康和心理健康。试验注册兰开夏郡教学医院NHS基金会信托基金的研究部门SE-259。或查看工作日或周末的子组。结论研究发现驳斥了长期存在的迷信，即“安静”一词会影响临床工作量，因此不应避免。在人员严重短缺和与工作相关的压力日益增加的时代，医生应寻求其他方法来增强适应力并保护他们的健康和心理健康。试验注册兰开夏郡教学医院NHS基金会信托基金的研究部门SE-259。医生应寻求其他方法来增强适应力并保护他们的健康和心理健康。试验注册兰开夏郡教学医院NHS基金会信托基金的研究部门SE-259。医生应寻求其他方法来增强适应力并保护他们的健康和心理健康。试验注册兰开夏郡教学医院NHS基金会信托基金的研究部门SE-259。
