Resource Profile: 腦中風－就醫背景

此 Profile 說明本 IG 如何進一步定義 FHIR 的 Observation Resource，以呈現腦中風病人本次就醫的背景資料，包括就醫來源、到院方式、未住院註記、病人年齡與教育程度。

記錄腦中風登錄的就醫背景。每個項目建一筆 Observation，以 code 區分。同一來源、同一病人、同一項目在同一評估時點只建一筆。來源空白時不建立；無法辨識的來源代碼，原值保留在登錄表單（StrokeRegistryResponse）。病人年齡照登錄數值填寫。

Usages:

• Use this Profile: 腦中風－個管系統個案資料包 and 腦中風－EVT 登錄個案資料包
• Examples for this Profile: Observation/stroke-arrival-mode-example, Observation/stroke-education-level-example and Observation/stroke-patient-age-example

You can also check for usages in the FHIR IG Statistics
