About project

The Challenge

The hospital network that launched OkDoc relied on a decades-old scheduling system with no modern APIs and limited data accessibility. They wanted to provide a patient-friendly mobile app, but several challenges stood in the way:

• Legacy Integration: Connecting the app with a scheduling system never designed for mobile access.
• Data Security: Managing sensitive healthcare records under strict compliance requirements (HIPAA/GDPR).
• Real-Time Communication: Ensuring patients could message or call doctors without delays or dropped connections.
• Scalability: Preparing the system to support thousands of patients simultaneously.
• User Experience: Delivering a clean, intuitive interface for both patients and doctors, despite the complexity behind it.

Our Approach

We treated this project as a full-scale digital transformation, ensuring great patient experiences could be delivered seamlessly while connecting to a legacy hospital system from day one:

Step 1: Discovery & System Mapping

We began by analyzing the hospital’s legacy scheduling infrastructure and existing workflows:

• Mapped dependencies between the old system and staff operations.
• Conducted patient journey workshops to identify UX gaps.
• Defined integration touchpoints to enable secure, real-time data exchange.

Step 2: Designing Patient & Doctor Journeys

We created intuitive, secure interfaces for both user groups:

• Accessibility and compliance baked into every design decision.
• A patient app for booking, communication, file sharing, and prescriptions.
• A doctor dashboard for managing schedules, consultations, and digital notes.

Step 3: Building a Middleware Integration Layer

To bridge the old and new systems without disruption, we developed middleware that:

• Translated legacy data into modern APIs.
• Enabled real-time synchronization of appointments and availability.
• Allowed hospital staff to continue using their familiar tools while unlocking new capabilities.

Step 4: Secure HealthTech App Development

We delivered a feature-rich iOS app with:

• Encrypted chat and video calls.
• File sharing for lab results and medical documents.
• Push notifications and reminders for appointments and prescriptions.
• Automated digital prescriptions and discharge notes.

Step 5: Deployment & Compliance

The final system was deployed on AWS, ensuring resilience and compliance:

• Auto-scaling infrastructure for peak loads.
• End-to-end encryption across data flows.
• Monitoring and logging to meet HIPAA/GDPR standards.
• 24/7 availability with zero disruption to hospital operations.

Our Solution

Dedicatted’s approach to building OkDoc was centered on one principle: modernizing patient–doctor interactions without disrupting hospital operations. The challenge of integrating with a decades-old scheduling system shaped every decision we made, from architecture to UX.

We began by creating a custom middleware integration layer that acted as a bridge between the hospital’s legacy system and the new mobile app. This layer translated outdated system logic into modern APIs, enabling real-time synchronization of appointments, cancellations, and doctor availability. This ensured the hospital staff could continue using the tools they already knew, while patients gained access to a completely new, digital-first experience. On the patient side, we developed a feature-rich iOS application that delivered all core healthcare interactions in one place:

• Online appointment booking with instant confirmations.
• Secure chat and video calls, protected with end-to-end encryption.
• File sharing capabilities, allowing patients to send test results or images directly to their doctor.
• Digital prescriptions and discharge notes, stored safely within the patient’s profile for easy access.
• Push notifications and reminders, reducing missed appointments and ensuring treatment adherence.

For doctors, we built a dedicated dashboard integrated directly into the app ecosystem. This streamlined schedule management, provided instant access to patient documents, and introduced automation tools that reduced repetitive administrative tasks. Doctors could issue prescriptions or generate discharge notes with a few taps, allowing them to spend more time focusing on care rather than paperwork.

To support OkDoc’s full range of features, we built the solution on AWS with a focus on reliability, compliance, and patient trust. The infrastructure was designed to scale effortlessly during peak usage, protect sensitive data with advanced encryption, and enforce strict access controls so only authorized personnel could view patient information. Continuous monitoring and logging ensured full compliance with HIPAA, GDPR, and healthcare regulations, creating a secure and seamless telehealth ecosystem that empowers patients while maintaining the hospital’s operational integrity.
