如何从EPIC FHIR API获取OT记录与PT记录

我正尝试从DocumentReference API（涵盖临床记录、检验结果、LDA等）获取OT（作业治疗）记录与PT（物理治疗）记录，但未得到预期结果，需要技术支持。

我已排查所有DocumentReference端点、检验相关接口及列表等，尝试过以下接口：

https://fhir.epic.com/interconnect-fhir-oauth/api/FHIR/STU3/DocumentReference/e.q.BLfR29vX-T-.y0bQbKg3

相关参考：

• Epic DocumentReference API规范
• Epic平台截图

上述尝试均未获取到所需的OT记录与PT记录。我能看到进度记录，但无法获取，接口响应内容如下：
