To verify our hypothesis that 'there is periodicity in nurse call occurrence'.
It is difficult to plan nursing management because nursing tasks can vary widely, seemingly at random. One of the most useful pieces of information for decision-making is periodicity. If periodicity is present, it should be possible to predict the occurrence of tasks and make preventive strategies. In this study, we focused on the nurse call, which plays an important role in nursing practice.
We used nurse call logs that accumulated automatically when patients pushed the button. Data were obtained from 1 January 2014 to 30 September 2017 (1,369 days) in a university hospital. The total number was 5,982,935. Periodicity was verified by the autocorrelation function.
The value of the autocorrelation function increased regularly, which demonstrates there was periodicity in nurse call occurrence.
Our hypothesis was accepted. The presence of periodicity indicates that nurse call occurrence is not a random event but has a pattern.
If we can identify patterns such as the time that nurse calls frequently occur, managers can implement two strategies: one, assigning more nurses and two, moving tasks other than nurse calls to another time.
验证我们的假设，即“护士呼叫的发生具有周期性”。
由于护理任务差异很大，看似随机，因此难以规划护理管理。周期性是决策中最有用的信息之一。如果存在周期性，就应该能够预测任务的发生并制定预防策略。在本研究中，我们关注的是在护理实践中起重要作用的护士呼叫。
我们使用了患者按下按钮时自动累积的护士呼叫记录。数据来自一所大学医院2014年1月1日至2017年9月30日（1369天）。总数为5982935条。通过自相关函数验证周期性。
自相关函数的值有规律地增加，这表明护士呼叫的发生具有周期性。
我们的假设得到认可。周期性的存在表明护士呼叫的发生不是随机事件，而是有规律的。
如果我们能够识别出护士呼叫频繁发生的时间等规律，管理人员可以实施两种策略：一是安排更多护士，二是将除护士呼叫之外的任务转移到其他时间。
