FHIR是什麼?它可以拿來做什麼?

  • 快捷式醫療服務互操作資源

    • 採用了現代的HTTP API技術

    • 使用者介面使用集成的HTML和CSS

    • 資料格式可選擇用於JSON或XML

Without FHIR

Without FHIR

  • 缺乏統一規範

  • 永遠做不完的重工

  • 難以支援行動裝置

  • 未來發展性不足

With FHIR

With FHIR

  • 支援資料標準格式一致

  • 與現代網頁技術標準一致

在解決資料交換標準後...

  • 你的FHIR不是我的FHIR

    • 大家都參考FHIR資料格式標準但是實做上仍有差異

數位疫苗護照應用的設計

故事是這樣的

  • PM:我們承接了聯測松計畫執行,也要有人參加響應?

  • 組長:我們來做一個數位疫苗護照應用參加聯測吧!

  • 組長:你去參加吧!
     

  • 所以我就開始開發數位疫苗護照了

參加聯測松?聯測松是什麼?

數位疫苗護照應用設計跟開發好後就可以參加聯測了

是要讓醫院、醫資廠商的系統,用符合HL7組織制定的國際醫療資料標準來互通資料,打破資料溝通障礙,改善未來國內外醫療資料的互通性。

聯測松有多個賽道,該選擇哪幾個?

選擇與產品有關符合的賽道

搞懂要聯測的產品是Consumer還是Producer

聯測松時程

  • 各種資料格式標準研討

  • 募集廠商

  • 舉辦聯測工作坊(沒參加)

  • 廠商報名聯測活動(組長統一報名)

  • 聯測與賽道線上說明(沒參加看影片記錄)

  • 用藥疫苗線上討論(跟我聯測有關有參加)

  • 預測活動(有參加)

  • 聯測活動當天(共三天)(有參加)

2022聯測松時程

聯測松–預測活動

  • 教你如何操作與設定Gazelle系統

  • 熟悉賽道的測項流程進行方式

聯測松–聯測設定

  • 在產品上開發設定聯測可以用的功能

聯測松–聯測設定

  • 在產品上開發設定聯測可以用的功能

聯測松–聯測與產品情境設計

聯測松–當天聯測活動

聯測松–當天聯測活動&心得

  • 總共3天

  • 類黑客松

  • 隔壁不太會程式技術的會問你問題

  • 改程式→送測項驗證→改程式...

  • 前端UI記得要有Debug模式

    • React Syntax Highlighter顯示回應與請求的JSON payload

    • 聯測有些測項會需要這個截圖

  • 會用cURL或是Postman會很有幫助

  • 與督察員「討論」測項不通過的原因

  • 一天比一天還要少人

  • 接完大會的FHIR server可以去接別人的
