HemoTrack Web Application

HemoTrack is a PHP/MySQL web application designed to manage blood donation operations. It includes donor search, blood request handling, appointment booking, newsletter subscriptions, and a comprehensive admin panel for managing donors, inventory, FAQs, blogs, and more. Admins log in via the login.php page using credentials stored in admin_info (admin/admin) and access the dashboard at dashboard.php.For demo logins use: Username:admin Password:admin

In addition, HemoTrack provides a complete blood bank management workflow system with the following advanced features:

• Blood Collection Management:
  Records blood donations linked to donors, including blood group, units collected, notes, and automatic expiry dates (42 days). Updates both the blood_units and blood_inventory tables while tracking collection status.
• Testing & Screening:
  Allows collected blood to be marked as safe or unsafe. Unsafe units are automatically removed from inventory. Maintains notes history and logs all testing results.
• Storage & Inventory Management:
  Provides real-time tracking of blood inventory by group, highlights low stock levels (less than 5 units), tracks last updated timestamps, and displays current stock along with units nearing expiry.
• Expiry Management:
  Automatically identifies near-expiry or expired blood units, allows marking them as expired, and deducts them from inventory accordingly.
• Inventory Adjustment:
  Supports manual stock adjustments (both addition and subtraction), including negative adjustments for damaged or unusable blood. Requires notes and prevents negative inventory using safe constraints.
• Hospital Request Management:
  Handles hospital blood requests with options to reserve and approve requests. Ensures sufficient inventory before reservation and prevents over-allocation.
• Blood Issuing System:
  Enables issuing blood to patients for approved or pending requests, updates request status to fulfilled, and logs issuance activities.
• Transaction Logging System:
  Maintains a centralized audit trail of all operations including registration, collection, testing, inventory updates, and issuing. Captures details such as stage, type, blood group, units, user, and notes.
• Advanced Transaction Filtering:
  Allows filtering transaction logs by stage, type, blood group, and date range for easy tracking and reporting.
• Multi-Stage Workflow Interface:
  Provides a tab-based navigation system covering all operational stages:
  Donor Registration, Blood Collection, Testing & Screening, Storage & Inventory, Inventory Adjustment, Hospital Requests, Issue to Patient, and Transaction Logs.
• Status Tracking System:
  Tracks the full lifecycle of blood units:
  collected → testing → safe/unsafe → stored → reserved → issued / expired
• Data Validation & Error Handling:
  Ensures input validation (e.g., required fields, positive units), displays success/error messages, and prevents invalid operations.
• Relational Data Management:
  Maintains structured relationships between donors, blood units, transactions, and requests for consistency and traceability.
