概括
这项研究评估了使用HL7 v2.5.5构建的临床数据库的HL7 FHIR® (FHIR) 可重复性. 虽然大多数数据成功地绘制了地图,但缺少的标准代码和值不准确性突出显示了在EHR系统中改进FHIR实施的领域.
科学领域:
- 医疗信息学 医疗信息学
- 临床数据管理 临床数据管理
- 互操作性标准 互操作性标准
背景情况:
- 6NC-EHRs数据库 (6NC-EHRsDB) 汇总了来自六个国家电子健康记录 (EHR) 的临床数据.
- HL7 v2.5 是用于电子健康记录数据交换的广泛使用的标准.
- HL7 FHIR® (快速医疗互操作性资源) 是一个新的标准,旨在提高数据互操作性.
研究的目的:
- 在转换为HL7 FHIR®时,评估在HL7 v2.5中构建的数据库的可重复性.
- 为了确定临床数据的FHIR实施中的差异和改进领域.
主要方法:

Hospitals provide inpatient and outpatient services. Inpatient services provide care to patients that stay in the hospital for an extended period, ranging from days to months. Examples of inpatient services include intensive care units, hospital wards, or surgeries. Outpatient services provide care to patients who come to a hospital for a diagnostic or treatment but do not stay overnight —for example, diagnostic tests, surgical procedures, or health education.
