概括

临床决策支持系统 (CDSS) 中的生成人工智能并没有显著改善模拟中的用户采用. 虽然提高了所感知的努力,但信任和工作流的问题仍然是整合AI工具到医疗保健中的关键障碍.

科学领域:

医疗信息学医疗信息学
医疗保健中的人工智能
临床决策支持系统临床决策支持系统

背景情况:

生成型人工智能 (GenAI) 具有增强临床决策支持系统 (CDSS) 的潜力.
GenAI对CDSS在临床实践中的采用和可用性的实际影响仍然在很大程度上未得到量化.
了解影响采用因素对于成功实施人工智能驱动的医疗保健工具至关重要.

研究的目的:

评估GenAI增强的CDSS,命名为"GutGPT",与标准AI仪表板相比对用户采用的影响.
评估GenAI对行为意图的影响,这是采用技术的关键指标,使用技术接受和使用统一理论 (UTAUT).
探索二次结果,包括决策准确性和用户对信任和工作流集成的定性反.

主要方法:

一个基于模拟的随机试验,涉及临床学员管理急性上部胃肠道出血病例.
参与者被分配到GenAI增强的GutGPT或比较AI仪表板中.
测量的主要结果是行为意图 (UTAUT);次要结果包括决策准确性和定性见解.

主要成果:

共有106名参与者 (52名GutGPT,54名比较者) 完成了这项研究.
GutGPT用户报告了显著更高的努力预期,表明感知到的易用性.
在GenAI和对照组之间的行为意图中没有发现显著差异;定性数据显示了对信任和工作流集成的担忧.

结论:

仅仅通过GenAI在此方面提供的可用性增强,就不足以保证更好地采用临床决策支持系统.
解决用户信任和无工作流集成对于在临床环境中成功实施GenAI驱动的CDSS至关重要.
需要进一步的研究,特别是涉及现实世界的临床整合和患者结果的研究,以充分确定GenAI在CDSS中的价值.

Assessment of the Gastrointestinal System I: Subjective Data

Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health History
The initial step in assessing the GI system is obtaining a comprehensive health history. This includes inquiring about the patient's history or presence of problems...

Assessment of the Gastrointestinal System II: Health Perception Pattern

Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:

Blinding

Blinding

Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.
