Abstract：
BACKGROUND: Viscoelastic hemostatic assays, such as rotational thromboelastometry (ROTEM) or thromboelastography, enable prompt diagnosis and accelerate targeted treatment. However, the complex interpretation of the results remains challenging. Visual Clot-a situation awareness-based visualization technology-was developed to assist clinicians in interpreting viscoelastic tests.
OBJECTIVE: Following a previous high-fidelity simulation study, we analyzed users\' perceptions of the technology, to identify its strengths and limitations from clinicians\' perspectives.
METHODS: This is a mixed qualitative-quantitative study consisting of interviews and a survey. After solving coagulation scenarios using Visual Clot in high-fidelity simulations, we interviewed anesthesia personnel about the perceived advantages and disadvantages of the new tool. We used a template approach to identify dominant themes in interview responses. From these themes, we defined 5 statements, which were then rated on Likert scales in a questionnaire.
RESULTS: We interviewed 77 participants and 23 completed the survey. We identified 9 frequently mentioned topics by analyzing the interview responses. The most common themes were \"positive design features,\" \"intuitive and easy to learn,\" and \"lack of a quantitative component.\" In the survey, 21 respondents agreed that Visual Clot is easy to learn and 16 respondents stated that a combination of Visual Clot and ROTEM would help them manage complex hemostatic situations.
CONCLUSIONS: A group of anesthesia care providers found Visual Clot well-designed, intuitive, and easy to learn. Participants highlighted its usefulness in emergencies, especially for clinicians inexperienced in coagulation management. However, the lack of quantitative information is an area for improvement.

摘要：
背景：粘弹性止血试验，如旋转血栓弹力图（ROTEM）或血栓弹力图，及时诊断，加速针对性治疗。然而,对结果的复杂解释仍然具有挑战性.VisualClot是一种基于情境感知的可视化技术，旨在帮助临床医生解释粘弹性测试。
目标：根据先前的高保真模拟研究，我们分析了用户对这项技术的看法，从临床医生的角度确定其优势和局限性。
方法：这是一项由访谈和调查组成的定性-定量混合研究。在高保真模拟中使用VisualClot解决凝血方案后，我们采访了麻醉人员，了解新工具的优缺点。我们使用模板方法来识别面试回答中的主要主题。从这些主题来看,我们定义了5个语句，然后在问卷的李克特量表上进行评级。
结果：我们采访了77名参与者，其中23人完成了调查。通过分析面试回复，我们确定了9个经常被提及的主题。最常见的主题是“积极的设计特征，“\”直观易学，\"和\"缺乏定量成分。\"在调查中,21名受访者同意视觉凝块易于学习，16名受访者表示视觉凝块和ROTEM的组合将帮助他们管理复杂的止血情况。
结论：一组麻醉护理提供者发现，直观，和容易学习。与会者强调了它在紧急情况下的有用性，特别是对于没有凝血管理经验的临床医生。然而,缺乏定量信息是一个需要改进的领域。
