A clinical diagnosis is a decision-making process that consists of not only the final diagnostic decision but also a series of information seeking decisions. Members of a patient-care team such as nurses, residents, and attending physicians play different roles but work collaboratively during this process. To better support the different roles and their collaborations during this process, we need to understand how different users interact with decision support systems. We developed SRCAST-Diagnosis to test how nurses, residents, and attending physicians use decision support system to improve diagnosis accuracy and resource efficiency. Nurses seemed more willing to take recommendations and therefore saved a greater amount of lab resources, but made less improvements on diagnosis accuracy. Attending physicians appeared more cautious in accepting SRCAST-Diagnosis recommendations. These findings will provide useful information for future CDSS design to support better collaborations of team members.
临床诊断是一个决策过程，它不仅包括最终的诊断决策，还包括一系列寻求信息的决策。患者护理团队的成员，如护士、住院医生和主治医生，扮演着不同的角色，但在这个过程中协同工作。为了在这个过程中更好地支持不同的角色及其协作，我们需要了解不同用户如何与决策支持系统进行交互。我们开发了SRCAST-Diagnosis来测试护士、住院医生和主治医生如何使用决策支持系统来提高诊断准确性和资源效率。护士似乎更愿意接受建议，因此节省了大量的实验室资源，但在诊断准确性方面的提高较少。主治医生在接受SRCAST-Diagnosis建议时显得更为谨慎。这些发现将为未来的临床决策支持系统设计提供有用信息，以支持团队成员更好地协作。
