built an EMR system

Technology's advancements have provided more innovative ways to store patients’ records and other relevant information. Currently, healthcare organizations move towards completely electronic systems to keep all medical records in one location - a centralized database. This will help physicians and different medical staff get the essential patient information quicker and easier. According to recent statistics, 86.9% of office-based physicians in the US are already using electronic medical records (EMR) software to manage their patients’ records. Moreover, the global hospital EMR software market will amount to 20.7 billion U.S. dollars by 2025. With such adoption rates risen, we’ve decided to develop an electronic medical records system from scratch. Let’s dive into the details below!

What exactly is an electronic medical records system?

Basically, an electronic medical records (EMR) system is a digital version of all the health-related information designed around the unique workflows of the healthcare organization. Thanks to the electronic medical records system, you can find such information as medical history, diagnoses, medications, lab results, immunization dates, allergies, doctor's notes and recommendations. Sometimes, the terms electronic medical record and electronic health record (or “EMR” and “EHR”) are used interchangeably. However, they are not the same. EMR systems have a focus on a patient's medical and treatment history in one practice while EHR systems include clinical data collected in the provider’s office that can be shared with other health care providers.

Types of electronic medical records systems

Here you will find various types of EMR software that meet any healthcare organisation’s needs and requirements. Keep on reading to learn more!

  • Cloud-based: this type of software allows healthcare providers to keep all the medical information about patients in the cloud and access it online.
  • ONC-certified: means that EMR systems have certification established by the Office of the National Coordinator for Health IT and give healthcare providers and patients confidence that the systems they use store their data securely and maintain confidentiality.
  • Behavioral/Mental Health EMR: designed around the unique workflows of mental health practices, these systems allow specialists who serve people seeking help from behavioral health challenges and provide them with specific options that simplify the care delivery, documentation and billing processes.
  • Medical Billing Software: used by healthcare providers to process patients’ statements and insurance claims more quickly and easily by automating administrative tasks.

Why do you need an electronic medical records system?

Healthcare organizations have been forced to invest in EMR solutions to meet the rapidly changing demand for a higher quality of care. Patient-related data housed on the EMR system allows them to share it within the clinic and get a more complete picture of patient treatment and medical history. Moreover, this solution is also helpful if you need the following:

  • To make electronic medical records scalable by turning paper-based patients’ charts into electronic ones
  • To reduce the number of duplicate tests
  • To increase productivity by enhancing patient workflow
  • To reduce errors within the medical practice
  • To process patients’ billing accurately and efficiently
  • To deliver advanced e-prescribing and clinical documentation

However, we should mention that these are not all advantages offered by the EMR system.

What’s the idea of the project?

The adoption of digital technologies has accelerated changes in the healthcare sector. Along with the technological changes, the ways the healthcare providers deliver healthcare services to patients are reshaping. That’s where EMR systems come into play. With a wide range of functionality, it allows experts to make healthcare more driven effectively. Not only can they access critical patient data in one click and share it with other staff within the clinic, but the system also helps them process payment and insurance claims quickly, schedule patients as well as update information about the patients. Having vast experience in such sectors as logistics, healthcare, eLearning, eCommerce and recruitment, DDI Development team can turn any idea into a real product. Recently, we developed and implemented an EMR system that helps our client to do the following:

  • eliminate paper-based records and save space
  • cut down operational costs
  • speed up billing process
  • improve documentation
  • provide clinical alerts and reminders

The development process of the electronic medical records system

Here you can find more details about the development process of the electronic medical records solution.

development process of the EMR solution


To create an EMR system, we used the agile methodology. Thanks to this methodology, we could better coordinate the development process as well as keep the balance even when the workload was extremely heavy. The development team consisted of the following specialists:

  • 1 Business analyst (BA)
  • 1 Project manager (PM)
  • 2 UI/UX designers
  • 2 Front-end engineers
  • 2 Quality assurance engineers (QA)
  • 2 Backend engineers
  • 1 iOS engineer
  • 1 Android engineer


There were several reasons to choose the agile software development methodology. Let’s take a closer look at them below:

  • The team could respond to changes by following a development plan
  • Working software took higher priority over comprehensive documentation
  • We could fix any error in the middle of the project.


At the very start, our Business Analyst interviewed a client to gather requirements and document them to prepare functional specifications. Only by analyzing all the requirements could we make sure that the future EMR system would work as the client wanted. Once all the requirements were identified, our team was able to define the users’ roles - physician, patient and administrator - with the following features and functionalities:

  • Patient portal
  • Scheduling
  • Recommendations
  • E-prescribing
  • Billing
  • Reporting

According to the documentation, the Project Manager provided the client with a preliminary estimate and suggested the roadmap for the development process of the EMR system. Once it was approved, the team broke down the planned scope of work (so-called Backlog) into smaller parts named 2-week sprints. The development team started the design, development and testing process once they received which features from the backlog would be developed by the end of the sprint. The development process took 12 months. Once the EMR solution was free of bugs, we launched it and made improvements based on the client’s and users’ feedback.

User Roles
