Paramedics work in a highly complex and unpredictable environment which is characterized by ongoing decision-making. Decisions made by paramedics in the prehospital setting have implications for patient safety, transport, treatment, and health resource utilization. The objective of this study was; a) to understand how paramedics conduct decision-making in the field, and b) to develop a grounded theory of paramedic decision-making in the prehospital setting.
This study was conducted using classical grounded theory. Paramedics (n = 13) with five or more years' experience, who worked in a large urban center in Western Canada were interviewed. Field observations were conducted, each lasting 12 h, with five different ambulance crews. The data were analyzed and coded using the constant comparative method.
The resultant theory, Creative Adapting in a Fluid Environment, indicates paramedic decision-making is a fluid iterative process. Unpredictable and dynamic features of the prehospital environment require paramedics to use a flexible and creative approach to decision-making. The model consists of the three categories constructing a malleable model, revising the model, and situation-specific action. Two additional components, safety and extrication, are considered at each stage of the call. These two components in conjunction with the three categories influence how decisions are made and enacted.
Paramedic decision-making is highly contextual and requires accurate interpretation and flexible cognitive constructs that are rapidly adaptable. Evaluation of paramedic decision-making needs to account for the complex and dynamic interaction between the environment, patient characteristics, available resources, and provider experience and knowledge.
护理人员在高度复杂且不可预测的环境中工作,其特点是需要持续进行决策。护理人员在院前环境中做出的决策对患者安全、转运、治疗及卫生资源利用都有影响。本研究的目的是:a)了解护理人员在现场如何进行决策,以及b)构建一个关于院前环境中护理人员决策的扎根理论。
本研究采用经典扎根理论。对在加拿大西部一个大型城市中心工作、有五年或以上经验的护理人员(n = 13)进行了访谈。对五支不同的救护车队进行了实地观察,每次观察持续12小时。使用持续比较法对数据进行分析和编码。
由此得出的理论“在动态环境中创造性适应”表明,护理人员的决策是一个动态的迭代过程。院前环境的不可预测性和动态特征要求护理人员采用灵活且有创造性的决策方法。该模型由构建可塑模型、修订模型和针对具体情况采取行动这三个类别组成。在呼叫的每个阶段都要考虑另外两个要素,即安全和解救。这两个要素与三个类别共同影响决策的制定和实施。
护理人员的决策高度依赖具体情境,需要准确的解读以及能够快速适应的灵活认知结构。对护理人员决策的评估需要考虑环境、患者特征、可用资源以及提供者经验和知识之间复杂的动态相互作用。
