科学领域:
- 医疗信息学 医疗信息学
- 临床决策支持系统 临床决策支持系统
- 电子健康记录电子健康记录
背景情况:
- 计算机化提供者订单输入 (CPOE) 系统MedChart将成为新西兰公共医院的国家标准.
- 评估CPOE系统的安全性和脆弱性对于预防药物错误和改善患者治疗结果至关重要.
研究的目的:
- 评估MedChart CPOE系统及其临床决策支持 (CDS) 能力对处方订单错误的脆弱性.
- 将MedChart的性能与其他CPOE系统在错误检测和预防方面进行比较.
- 调查不同订单工作流 (顺序与并发) 对系统漏洞的影响.
主要方法:
- 十名测试人员在MedChart培训环境中模拟了16个已发表的处方订购错误场景.
- 完成每个场景的难度被评分在一个5分利克特级别.
- 分组分析检查了多处方场景的顺序和并发订单工作流之间的差异.
主要成果:

Documentation of Nursing Diagnosis
1.2K
The nurse documents nursing diagnoses and enters them into the patient record. The identified patient's nursing diagnosis is either written out with a plan of care or entered into the electronic health record.
In some settings, data-driven computerized decision support systems are in place, allowing for more accurate nursing diagnoses. The database within one of these systems includes diagnostic labels defining characteristics, activities, and indicators for nursing. A nurse enters...

Pharmacovigilance
789
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.

Errors occurring during blood pressure monitoring
621
Blood pressure monitoring is a crucial clinical procedure in diagnosing and managing various cardiovascular conditions. Despite its significance, the accuracy of blood pressure measurements can be compromised by multiple factors, potentially leading to either falsely high or low readings. These inaccuracies are critical as they can significantly impact patient care. So, it is vital to understand these challenges deeply and adopt strategic approaches to minimize errors.
