How to Build an EHR

This is an in-depth series on how to build an Electronic Health Records (EHR) System MVP.

In this tutorial we’ll design and implement a vertical slice (frontend, backend, infra) of an EHR system from scratch (with enough context to understand how the pieces fit together), specifically the Appointment Scheduling feature between Patients and Practitioners.

Tutorial Organization

This series is divided into the following parts:

Introduction: Overview of the series and key concepts.
Planning & Discovery: Event Storming, Example Mapping, and Domain-Driven Design.
UI/UX Design: Wireframing, Prototyping, and User Testing.
System Design: Architecture, Database, Security, and Integration.
DevSecOps: Infrastructure, CI/CD, Observability, and Security.
Frontend Implementation: Component Design, State Management, and User Interaction.
Backend Implementation: Data Modeling, API Design, and Clean Architecture.
Launch: Launch plan, retrospective, and next steps.

Note: Each part builds upon the previous one, providing a holistic view of the EHR system development process. Feel free to jump to the part that interests you the most or follow the series sequentially for a complete understanding.

Introduction

Welcome to this series on How to Build an Electronic Health Record (EHR) system. This tutorial is designed to guide you through the entire process of developing a robust, scalable, and secure EHR system, leveraging modern methodologies and best practices. Objective: Gain an understanding of the key concepts and assumptions in this tutorial. Familiarize yourself with the items in the Appendix and when you’re ready, proceed to kickoff the project in the next part: Planning & Discovery....

Discovery & Planning

The first step towards delivering a successful project is Discovery & Planning. This phase involves understanding the business domain, defining the scope, and identifying the key events, interactions, and workflows that need to be implemented. Objective: Perform Discovery & Planning for the Appointment Scheduling flow by producing the following artifacts: EHR: Big Picture Event Storm Appointment Scheduling: Domain Model Appointment Scheduling: Feature Requirements EHR: Project Plan Let’s start with creating the EHR: Big Picture Event Storm before creating the domain model and feature requirements....

System Design

Designing a system for an Electronic Health Record (EHR) involves several key components to ensure it meets the needs of healthcare providers, complies with regulatory requirements, and maintains the privacy and security of patient data. For this tutorial, we’ll focus on the Appointment Scheduling feature within the EHR application. Objective: Design the system architecture for Appointment Scheduling by producing the following artifacts: System Context Diagram Platform Diagram Component Diagram Let’s start with designing the System Context Diagram before creating the Platform Diagram....

🚧 DevSecOps Implementation

In this article, we’ll explore the key components of an EHR infrastructure, including servers, databases, and networking, and discuss best practices for designing and implementing a scalable, secure, and reliable system. 🚧 Draft / Work in Progress This page is currently a draft and a work in progress.
