Major postoperative morbidity and mortality remain common despite efforts to improve patient outcomes. Health information technologies have the potential to actualize advances in perioperative patient care, but failure to evaluate the usability of these technologies may hinder their implementation and acceptance. This protocol describes the usability testing of an innovative telemedicine-based intra-operative clinical support system, the Anesthesiology Control Tower, in which a team led by an attending anesthesiologist will use a combination of established and novel information technologies to provide evidence-based support to their colleagues in the operating room.
Two phases of mixed-methods usability testing will be conducted in an iterative manner and will evaluate both the individual components of the Anesthesiology Control Tower and their integration as a whole. Phase I testing will employ two separate "think-aloud" protocol analyses with the two groups of end users. Segments will be coded and analyzed for usability issues. Phase II will involve a qualitative and quantitative in situ usability and feasibility analysis. Results from each phase will inform the revision and improvement of the Control Tower prototype throughout our testing and analysis process. The final prototype will be evaluated in the form of a pragmatic randomized controlled clinical trial.
The Anesthesiology Control Tower has the potential to revolutionize the standard of care for perioperative medicine. Through the thorough and iterative usability testing process described in this protocol, we will maximize the usefulness of this novel technology for our clinicians, thus improving our ability to implement this innovation into the model of care for perioperative medicine.
The study that this protocol describes has been registered in clinicaltrials.gov as NCT02830126.
尽管人们努力改善患者预后，但术后严重发病和死亡情况仍然常见。健康信息技术有潜力实现围手术期患者护理的进展，但未能评估这些技术的可用性可能会阻碍其实施和接受。本方案描述了一种基于远程医疗的创新术中临床支持系统——麻醉控制塔的可用性测试，在该系统中，由主治麻醉师领导的团队将使用既定和新颖的信息技术组合，为手术室中的同事提供循证支持。
将以迭代方式进行两个阶段的混合方法可用性测试，评估麻醉控制塔的各个组件及其整体集成情况。第一阶段测试将对两组最终用户采用两种单独的“出声思考”协议分析。对片段进行编码并分析可用性问题。第二阶段将涉及定性和定量的现场可用性和可行性分析。每个阶段的结果将为在整个测试和分析过程中对控制塔原型的修订和改进提供依据。最终原型将以实用随机对照临床试验的形式进行评估。
麻醉控制塔有可能彻底改变围手术期医学的护理标准。通过本方案中描述的全面且迭代的可用性测试过程，我们将最大限度地提高这项新技术对临床医生的实用性，从而提高我们将这项创新纳入围手术期医学护理模式的能力。
本方案描述的研究已在clinicaltrials.gov上注册，注册号为NCT02830126。
