Dataset for "User-testing guidelines to improve the safety of intravenous medicines administration: a randomised in-situ simulation study"

Why did we carry out this research?
One out of every ten injections into veins in the UK is prepared or given in the wrong way. Some of these mistakes will cause unnecessary harm to the patient. To help prevent these mistakes, the NHS publishes the Injectable Medicines Guide (IMG). This NHS website tells nurses how to prepare each injection correctly. Some people think that the IMG is confusing for nurses. This is worrying, as research shows that confusing information can cause mistakes. So improving the design of the IMG might lead to fewer mistakes.

In the first part of this project, we used a process called “user testing” to find out what information nurses found confusing in the IMG. We then redesigned the IMG to solve these problems. In this part of the project, we wanted to find out if using our new design for the IMG made it safer to give injections.

What were we aiming to find out?
Our aim was to find out if nurses using our new IMG design made fewer mistakes than nurses using the original design.

How did we do this research?
We asked 273 nurses to prepare and give a dose of a pretend medicine to a model patient. They did this whilst they were working on a ward in one of five hospitals. To help the nurses with this task, they were randomly given either the original IMG design or our new design. We watched them whilst they prepared and gave the dose and recorded any mistakes that were made. We also timed how long it took. Then we asked the nurses to answer a questionnaire about how confident they felt using the IMG.

What data is included here?
This archive includes the documents we created to help us carry out this research, data on our participants and how many errors they made, and details of interviews we carried out with some nurses.

本研究旨在探究英国静脉注射中，每十次注射中就有一次以错误的方式进行准备或实施的情况。其中一些错误会导致患者遭受不必要的伤害。为了预防这些错误，英国国家卫生服务局（NHS）发布了《可注射药物指南》（IMG）。该NHS网站指导护士如何正确准备每一次注射。有些人认为IMG对护士来说难以理解。这一点令人担忧，因为研究表明，信息混乱会导致错误。因此，改进IMG的设计可能有助于减少错误。

在本项目的第一阶段，我们采用“用户测试”的方法，以了解护士在IMG中感到困惑的信息。随后，我们对IMG进行了重新设计以解决这些问题。在本阶段，我们希望探究使用我们新设计的IMG是否能使注射更加安全。

我们的研究目标是确定使用我们新设计的IMG的护士是否比使用原始设计的护士犯的错误更少。

我们是如何进行这项研究的？我们邀请了273名护士在一所医院的病房中为模拟患者准备并发放一种假药。他们被随机分配到使用原始IMG设计或我们的新设计。我们在他们准备和发放药物的过程中进行观察，并记录下任何所犯的错误。我们还记录了整个过程所需的时间。然后，我们让护士们回答关于使用IMG时他们感到自信的问卷调查。

本档案中包含了我们为进行这项研究所创建的文档，包括参与者的数据以及他们所犯错误的数量，以及我们与一些护士进行的访谈细节。
