A comprehensive consulting roadmap for Saudi German Hospital to launch a seamless online store for prescriptions, wellness, and booking, deeply integrated with existing hospital systems.
We architected a "Zero-Friction" flow that connects physical consultations to digital fulfillment, minimizing patient effort while maintaining strict medical compliance.
Doctor enters prescription into HIS (Hospital Information System) with specific dosage and duration.
HL7 message triggers API payload. Prescription object is created in E-Com DB linked to Patient MRN.
Patient receives SMS link. Clicking it opens the App with meds already in cart, pending checkout.
The core complexity lay in the bidirectional synchronization between the legacy on-premise HIS and the cloud-native e-commerce platform. We implemented a robust Enterprise Service Bus (ESB) pattern.
The system queries the EMR for patient allergies and contraindications in real-time before checkout. If a conflict affects the cart (e.g., potential drug interaction), the order is flagged for pharmacist review.
Checkout flow integrates with Insurance Gateways (Waseel/Nawn) to calculate patient copay instantly. Logic handles coverage rejection by offering full-pay overrides.
To prevent overselling, we implemented a "Soft Lock" mechanism. When a user adds an item to cart, middleware queries the specific hospital branch’s inventory and reserves the unit for 15 minutes.
Checkout is not just payment; it’s a medical validation gate. The logic checks for valid prescription expiry, insurance coverage limits, and controlled substance regulations before capturing payment.
Orders are routed to the nearest hospital pharmacy for packing. The system generates a digital pick-list for pharmacists. Once packed, a "Ready for Pickup" or "Out for Delivery" status triggers a patient notification.
