Seamless interoperability of ophthalmic clinical data is beneficial for improving patient care and advancing research through the integration of data from various sources. Such consolidation increases the amount of data available, leading to more robust statistical analyses, and improving the accuracy and reliability of artificial intelligence models. However, the lack of consistent, harmonized data formats and meanings (syntactic and semantic interoperability) poses a significant challenge in sharing ophthalmic data.
The Health Level 7 (HL7) Fast Healthcare Interoperability Resources (FHIR), a standard for the exchange of healthcare data, emerges as a promising solution. To facilitate cross-site data exchange in research, the German Medical Informatics Initiative (MII) has developed a core data set (CDS) based on FHIR.
This work investigates the suitability of the MII CDS specifications for exchanging ophthalmic clinical data necessary to train and validate a specific machine learning model designed for predicting visual acuity. In interdisciplinary collaborations, we identified and categorized the required ophthalmic clinical data and explored the possibility of its mapping to FHIR using the MII CDS specifications.
We found that the current FHIR MII CDS specifications do not completely accommodate the ophthalmic clinical data we investigated, indicating that the creation of an extension module is essential.
眼科临床数据的无缝互操作性有利于通过整合来自各种来源的数据来改善患者护理和推进研究。这种整合增加了可用数据的数量，从而进行更强大的统计分析，并提高人工智能模型的准确性和可靠性。然而，缺乏一致、协调的数据格式和含义（语法和语义互操作性）是眼科数据共享的一个重大挑战。
健康水平 7（HL7）快速医疗互操作性资源（FHIR）是医疗数据交换的标准，它是一个有前途的解决方案。为了促进研究中的跨站点数据交换，德国医学信息学倡议（MII）已经基于 FHIR 开发了一个核心数据集（CDS）。
这项工作研究了 MII CDS 规范是否适合交换训练和验证特定机器学习模型（用于预测视力）所需的眼科临床数据。在跨学科合作中，我们确定并分类了所需的眼科临床数据，并探讨了使用 MII CDS 规范将其映射到 FHIR 的可能性。
我们发现当前的 FHIR MII CDS 规范不完全适用于我们研究的眼科临床数据，这表明创建扩展模块是必要的。
