Key Aspects of Building EHR Software

A baseline EHR system should cover secure PHI storage, billing, health records management, and treatment planning. To boost medical staff productivity, EHR apps may be expanded with clinical decision support (CDS) capabilities and AI-powered convenience features, such as dictation and image recognition for quick document scanning.

At ScienceSoft, we understand our clients want to get fast ROI from their EHR initiatives, so we deliver the first working software version in 2–4 months. The cost of a full-fledged EHR system built from scratch may vary from $400,000 to $2,000,000, depending on the software's complexity. Use our free calculator to learn the cost for your case.

Sample EHR Development Plan

Below, ScienceSoft’s consultants describe a generalized plan for EHR software development. When working with clients, our team adjusts these steps to fit the needs of each unique project, including target market regulations, medical specialty specifics, and more.


Discovery stage

For software product companies

  • Analyzing the market of EHR products, identifying the competitors, and defining target customers and their needs.
  • Shaping an EHR concept, including competitive features like CDS modules, medical specialty features, AI capabilities, and more.
  • Creating a marketing strategy to promote the EHR product to hospitals, health networks, private practices, etc.
  • Planning the monetization approach and service options (e.g., subscription plans with access to basic or advanced EHR feature packs).
  • Identifying applicable EHR compliance requirements (e.g., HIPAA, GDPR, ONC, FDA).
  • Developing a business case with TCO and ROI calculations.

For healthcare providers

  • Analyzing the current care and billing operations to determine the business needs to be addressed with a new EHR.
  • Collecting user feedback on the current health records system.
  • Creating an EHR concept reflecting the needs of medical and administrative staff.
  • Developing the EHR adoption strategy.
  • Planning data migration from the former health records system.
  • Identifying applicable EHR compliance requirements (e.g., HIPAA, GDPR, ONC, FDA).
  • Developing a business case with TCO and ROI calculations.

If you build an EHR for US users and engage an outsourced team, you need to sign a Business Associate Agreement (BAA) with the vendor. According to HIPAA, this contract is a must for all parties that have access to PHI, as it guarantees proper data handling.

Requirements engineering, architecture, and integrations design

  • Defining functional and non-functional EHR requirements to create a software requirements specification.
  • Designing a secure-by-design and flexible EHR architecture (e.g., microservices-based).
  • Designing APIs to smoothly integrate EHR with popular healthcare software products or internal systems (clearinghouse software, laboratory information system, medical imaging software, and more).
  • Selecting a suitable tech stack (e.g., HIPAA-compliant hosting, cost-efficient and secure cloud components for scalable data storage).
  • Mapping the EHR usage risks and developing a risk mitigation plan.



Project planning

  • Selecting an approach to project management (Scrum, Kanban, etc.).
  • Planning the project team, timeframes, key milestones, KPIs, and budget.
  • Planning the ONC certification process (US only) or certification according to the requirements of other local authorities.
  • Creating a risk assessment and mitigation plan for EHR development (e.g., certification delays, scope creep).



UX and UI design

  • Conducting UX research to define user scenarios for all user roles (e.g., physicians, nurses, administrative staff).
  • Designing UX wireframes and testing the UX.
  • Creating UI prototypes for the EHR using the wireframes.

According to KLAS researchers, high EHR satisfaction rates increase the chances of physicians staying with their current employer by 5x. I recommend focusing on user convenience and easy navigation when designing the UX of the EHR. If you’re developing an EHR for your healthcare organization, you may engage your staff members (physicians, nurses, administrators) to review the UI prototypes, spot the pain points, and remove potential issues early. If you represent a software product company, we have MD consultants on board to check the UI from the target audience's point of view.

Iterative development and testing

  • Developing back end and front end in 2–4-week iterations.
  • Creating APIs for EHR integration with medical software or smart medical devices.
  • Implementing security features for PHI protection (e.g., role-based access, data encryption, MFA).
  • Testing the EHR (including functional, integration, performance, security, compliance, compatibility, and accessibility testing).




  • Updating the EHR usage risks matrix and project documentation to make sure all changes are reflected for future certification, support, and updates.
  • Conducting a HIPAA compliance pre-audit or GDPR compliance audit.
  • Submitting the EHR to the ONC-Authorized Testing Laboratory (for the US) or other local EHR certification bodies.
  • If the EHR features SaMD capabilities: submitting the software for premarket approval according to the FDA 501k program (US) or MDR requirements (EU).
  • Creating and publishing quick start guides for physicians, nurses, and other user groups.
  • For healthcare organizations: migrating healthcare data from the legacy systems.



EHR launch

  • EHR software deployment to the chosen environment and EHR launch.
  • For product companies: executing the marketing strategy to gain customers (e.g., utilizing online channels and industry conferences to promote the software, establishing interoperability with other popular medical software products).
  • For healthcare organizations: executing the EHR rollout and adoption strategy; training medical staff on the software use.



Support, maintenance, and evolution

  • Launching a help desk to handle questions and issues reported by the EHR users.
  • Monitoring user satisfaction and maintaining the EHR by fixing defects, resolving incidents, adding security patches to ensure compliance, and more.
  • Upgrading EHR functionality based on the user feedback.
