-# DH-HIS Quản Lý Giao Ban Hằng Ngày (Golang Standalone)
+# Phần Mềm Quản Lý Giao Ban Hằng Ngày (DH-HIS Web)
 
-Ứng dụng độc lập (Single Binary Executable) viết bằng **Golang**, nhúng toàn bộ giao diện Web, cơ chế quản trị kết nối CSDL PostgreSQL bảo mật mã hóa AES-256, khay hệ thống (System Tray) cho Windows, và chức năng tự động kiểm tra/cập nhật phiên bản từ Gitea Package/Release.
+Ứng dụng Node.js + Express + PostgreSQL phục vụ công tác giao ban bệnh viện hằng ngày, hỗ trợ phân tích đối chiếu đa chu kỳ và tương tác nhập liệu ghi chú trực tiếp.

-## 🌟 1. Điểm nổi bật & Tính năng chính
+## 2. Cách khởi động ứng dụng
-
-1. **Chỉ 1 file duy nhất (Single Binary Executable)**:
-   - Toàn bộ giao diện HTML, CSS, JavaScript, icon được nhúng trực tiếp vào file nhị phân qua `//go:embed`.
-   - Không cần cài Node.js, không cần thư mục `node_modules` hay web server bên ngoài.
-   - Dung lượng nhẹ: ~7.3 MB trên Windows (`.exe`) và ~6.8 MB trên Linux.
-2. **Khay hệ thống (System Tray)**:
-   - Chạy trên Windows có icon khay hệ thống, không hiện cửa sổ console đen (`-H windowsgui`).
-   - Menu gồm:
-     - 🌐 Mở Báo Cáo Giao Ban
-     - ⚙️ Quản Trị & Cấu Hình
-     - 📜 Xem Nhật Ký / Log App
-     - 🔄 Kiểm Tra Cập Nhật
-     - ❌ Thoát Ứng Dụng
-   - Chạy trên Linux Server tự động chuyển sang chế độ Daemon / Service nền ổn định.
-3. **Trang Quản Trị & Cấu Hình Kết Nối (`/admin`)**:
-   - Tùy chỉnh Cổng Web (Port), đường dẫn quản trị.
-   - Cấu hình kết nối PostgreSQL: Host, Port, User, Password, CSDL mặc định.
-   - **Mã hóa AES-256-GCM**: Mật khẩu và Token được tự động mã hóa dạng `ENC(...)` khi lưu vào `config.json`, không lộ bản rõ.
-   - Nút **"Thử Kết Nối (Test Connection)"** kiểm tra thông suốt CSDL ngay trên web.
-   - Bảng quản lý danh sách CSDL các bệnh viện hiển thị trên dropdown.
-4. **Nhật Ký Thời Gian Thực (Live Log Viewer)**:
-   - Ring buffer 500 dòng log gần nhất lưu trong bộ nhớ và ghi ra `logs/app.log`.
-   - Xem log trực tiếp trên trang quản trị có lọc theo cấp độ (INFO, WARN, ERROR, SQL) và tự động cuộn (Auto-scroll).
-5. **Tự động kiểm tra & cập nhật phiên bản (Gitea Self-Update)**:
-   - Kết nối với Gitea Releases / Generic Package Registry qua Token cá nhân.
-   - Phát hiện phiên bản mới, xem ghi chú phát hành (*Release Notes*), tải và tự thay thế file binary đang chạy (*in-place binary replacement*).
-

-
-## 🚀 2. Hướng dẫn biên dịch (Build)
-
-Chạy script biên dịch có sẵn:
 ```bash
-./build.sh
+cd /home/othau/dh-coding/dh-giaoban-web
+node server.js
 ```
-Kết quả sinh ra 2 file:
+Mở trình duyệt truy cập: **http://localhost:3000** (hoặc `http://<IP_MÁY>:3000`).
-- `web-giao-ban`: File thực thi standalone cho Linux.
-- `web-giao-ban.exe`: File thực thi standalone cho Windows (chỉ cần copy sang máy Windows là click đúp chạy).
 
----
+## 3. Các tính năng chính
+1. **Giao ban Ngoại trú**:
+   - Thống kê lượt khám BHYT, Thu phí, Chuyển viện theo các khoa (Khám bệnh, Ngoại, Nội, CSSKSS, Nhi, YDCT,...).
+   - Thống kê Bệnh án ngoại trú (Mới vs Tái khám) và chuyên khoa YDCT (Điện châm, VLTL, Sắc thuốc, Cấy chỉ).
+   - Tổng hợp số liệu Cận lâm sàng: Xét nghiệm (Huyết học, Sinh hóa, Nước tiểu, Miễn dịch, Đông máu) & CĐHA (Nội soi, Xquang, Siêu âm, CT, ECG).
+   - Top 10 chẩn đoán bệnh ngoại trú theo mã ICD-10.
+   - So sánh số liệu giữa 2 khoảng thời gian không liên tục (Ví dụ: Tháng 1 vs Tháng 3/10) và biểu diễn bằng biểu đồ cột.
 
-## 💻 3. Hướng dẫn sử dụng trên Windows
+2. **Giao ban Nội trú**:
-
+   - Tổng hợp lưu lượng bệnh nhân theo các khoa: Bệnh cũ (tồn đầu), Bệnh mới (nhập viện), Xuất viện (Ổn xin về, Nặng xin về, Trốn, Chuyển viện, Tử vong), Bệnh hiện còn, Bệnh theo dõi, Chăm sóc Cấp I.
-1. Copy file `web-giao-ban.exe` vào thư mục bất kỳ trên máy Windows (Ví dụ: `D:\DH-HIS\GiaoBan\`).
+   - Biểu đồ cột phân tích lưu lượng và so sánh đa chu kỳ.
-2. Nhấp đúp vào `web-giao-ban.exe` để chạy.
+   - **Bảng 3 (Danh sách bệnh nhân Chuyển viện)** & **Bảng 4 (Danh sách bệnh nhân Theo dõi & CS Cấp I)**:
-3. Icon chữ thập y tế màu xanh sẽ xuất hiện ở **Khay hệ thống (System Tray)** góc dưới bên phải màn hình.
+     - Hiển thị đầy đủ: Họ tên, Địa chỉ, Ngày VV/RV, Khoa, Chẩn đoán chính/phụ, Tóm tắt kết quả CLS.
-4. Nhấp chuột phải vào icon khay hệ thống:
+     - **Cột Ghi chú thông minh**: Các khoa tự nhập liệu trực tiếp trên lưới; hệ thống tự động lưu vào CSDL ngay khi chuyển ô.
-   - Bấm **"Mở Báo Cáo Giao Ban"** để mở trình duyệt xem số liệu.
-   - Bấm **"Quản Trị & Cấu Hình"** để đổi thông số IP máy chủ hoặc CSDL.
-   - Bấm **"Xem Nhật Ký / Log App"** để kiểm tra log hoạt động.
-   - Bấm **"Kiểm Tra Cập Nhật"** để cập nhật phần mềm mới từ Gitea.
-   - Bấm **"Thoát"** để dừng ứng dụng.

-## 🐧 4. Quản lý dịch vụ trên Linux (Systemd Service)
-
-- **Xem trạng thái**: `./status.sh` hoặc `sudo systemctl status web-giao-ban`
-- **Khởi động**: `./start.sh` hoặc `sudo systemctl start web-giao-ban`
-- **Dừng dịch vụ**: `./stop.sh` hoặc `sudo systemctl stop web-giao-ban`
