Evaluating a handheld decision support device in pediatric intensive care settings

Objective: To evaluate end-user acceptance and the effect of a commercial handheld decision support device in pediatric intensive care settings. The technology, pac2, was designed to assist nurses in calculating medication dose volumes and infusion rates at the bedside.
Materials and Methods: The devices, manufactured by InformMed Inc., were deployed in the pediatric and neonatal intensive care units in two health systems. This mixed methods study assessed end-user acceptance, as well as pac2’s effect on the cognitive load associated with bedside dose calculations and the rate of administration errors. Towards this end, data were collected in both pre- and post-implementation phases, including through ethnographic observations, semi-structured interviews, and surveys.
Results: Although participants desired a handheld decision support tool such as pac2, their use of pac2 was limited. The nature of the critical care environment, nurses’ risk perceptions, and the usability of the technol...

研究目标：评估一款商用手持决策支持设备在儿科重症监护环境中的终端用户接受度及其应用效果。该设备（pac2）旨在协助护士在床旁开展药物剂量容积与输液速率的计算工作。
材料与方法：本研究使用的设备由InformMed公司（InformMed Inc.）制造，部署于两家医疗系统的儿科重症监护室与新生儿重症监护室中。本项混合方法研究评估了终端用户接受度，以及pac2对床旁药物剂量计算相关认知负荷与给药错误率的影响。为此，研究在设备部署前与部署后两个阶段收集数据，数据采集方式包括民族志观察、半结构化访谈与问卷调查。
研究结果：尽管受试者期望使用pac2这类手持决策支持工具，但他们对pac2的实际使用较为有限。重症监护环境的特性、护士的风险感知以及该设备的易用性...
