Acute bleeding is an omnipresent challenge for all physicians. Uncontrolled hemorrhage is the most common preventable cause of death after trauma worldwide. In different surgical disciplines, hemorrhage represents an independent risk factor for increased postoperative morbimortality, directly affecting patients' outcomes. This study asked anesthesiologists about their personal perceived challenges when treating bleeding patients.
This investigator-initiated, prospective, international, dual-center, mixed qualitative and quantitative study interrogated anesthesiologists about what they found easy and what difficult in treating acutely bleeding patients. Following the template approach for qualitative research, we identified major and minor topics through free inductive coding and word count. In a second step, we derived ten statements from the participants' answers. Using a field survey, we then asked the participants to rate their level of agreement with the derived statements. We analyzed the answers using one sample Wilcoxon test and the Mann-Whitney test.
We included a total of 84 physicians in the qualitative interrogations and a different group of 42 anesthesiologists in the quantitative part. We identified 11 major topics and 19 associated subtopics. The main topics and the degree of agreement (here as agree or strongly agree) were as follows: "Complexity of the topic" (52.4% agreed to find the topic complex), "Cognitive aids" (92.9% agreed to find them helpful), "Time management" (64.3% agreed to feeling time pressure), "Human factors" (95.2% agreed that human factors are essential), "Resources" (95.2% agreed that resources are essential), "Experience" and "Low frequency of cases" (57.1% agreed to lack practice), "Diagnostic methods" (31.0% agreed that the interpretation of test results is difficult), "Anticoagulation" (85.7% agreed to it being difficult), "Treatment" (81.0% agreed to knowing the first therapeutic steps), and "Nothing".
Anesthesiologists in two large tertiary care facilities in different parts of the world found coagulation management, especially in anticoagulated patients, complex. We identified the delayed diagnostic test results and their interpretation as challenges. Resources, treatment protocols and human factors such as team communication were perceived to facilitate management. Future studies should explore the challenges in smaller hospitals and other parts of the world and test new technologies addressing the identified difficulties.
急性出血是所有医生普遍面临的挑战。在全球范围内,不受控制的出血是创伤后最常见的可预防死亡原因。在不同的外科领域,出血是增加术后发病率和死亡率的独立危险因素,直接影响患者的预后。本研究询问麻醉师在治疗出血患者时他们个人认为的挑战。
这是一项由调查员发起的、前瞻性的、国际性的、双中心的、混合定性和定量研究,询问麻醉师在治疗急性出血患者时哪些方面容易,哪些方面困难。本研究采用定性研究的模板方法,通过自由归纳编码和字数统计确定主要和次要主题。在第二步中,我们从参与者的回答中得出了十个陈述。然后,我们使用现场调查让参与者对得出的陈述进行评级。我们使用单样本 Wilcoxon 检验和 Mann-Whitney 检验对答案进行分析。
我们总共对 84 名医生进行了定性询问,并在定量部分对另一组 42 名麻醉师进行了询问。我们确定了 11 个主要主题和 19 个相关子主题。主要主题和同意程度(这里表示同意或强烈同意)如下:“主题的复杂性”(52.4%的人同意该主题复杂),“认知辅助工具”(92.9%的人同意这些工具有用),“时间管理”(64.3%的人同意感到时间紧迫),“人为因素”(95.2%的人同意人为因素至关重要),“资源”(95.2%的人同意资源至关重要),“经验”和“案例频率低”(57.1%的人同意实践机会少),“诊断方法”(31.0%的人同意测试结果的解读困难),“抗凝”(85.7%的人同意其难度),“治疗”(81.0%的人同意知道第一治疗步骤),以及“无”。
来自世界不同地区两个大型三级保健机构的麻醉师发现凝血管理,特别是在抗凝患者中,较为复杂。我们发现延迟的诊断测试结果及其解读是一个挑战。资源、治疗方案和人为因素(如团队沟通)被认为有助于管理。未来的研究应在小医院和世界其他地区探索这些挑战,并测试解决已确定困难的新技术。
