Step 1: understand which EMR you need
More and more users are concerned not with unauthorized access to confidential medical information, but with data errors that can negatively affect the quality of treatment. At the same time, every fifth patient found such an error in his EMR. Source
Before you start creating an EMR system for your business, you need to understand what kind of software you need: what tasks, functions, design, navigation, architecture, technologies you need to implement. To understand all this, you need to perform the following steps (research):
- Define your strategic goals. These should be specific and understandable goals that can be measured. For example, if your goal is to reduce the time it takes to visit a patient, then you need to explore the possibility of integrating the online appointment function, and then measure whether it has reduced the time it takes to see a patient.
- Talk to your users about their needs. Patients, clinical staff, insurance companies, and other future users of the EMR you create can provide valuable insights into what software needs to be built (design, function, etc.) and how to make it more orient towards patients and hospital.
- Analyze the solutions of your competitors. So you will understand which solutions of your competitors were liked by users, and which turned out to be controversial or useless. Thanks to this, there will be no need to reinvent the wheel and repeat the mistakes of other companies.
- Document your requirements. Once you have identified your strategic goals, user needs, and competitive advantages, you can begin to transform this information into business requirements, which will then be used to write a functional specification for developing EMR software for your business.
Step 2: study the relevant laws

So, to understand how to create EMR software, you need to study the laws related to medical application development and sensitive data. These are the key laws and certification systems in the US and EU:
- GDPR. Regulates the rules for the collection, management and protection of personal data in the EU. Imposes a duty on a healthcare provider to ensure that data such as names, addresses, demographics, medical diagnoses and more are highly protected, which, among other things, includes creating a system to instantly delete or correct information.
- EuroRec. It is a certification system for software development that must be passed by all providers of EMR and EHR solutions operating within the EU or using data from EU citizens.
- HIPAA and HITECH. Regulate the rules for the use and storage of personal data, as well as the rules (standards) for the development of medical software in the United States. There is a detailed guide on GitHub on how to create HIPAA compliant EMR software.
- Medicare and Medicaid. In 2011, CMS established the Targeted Use Program, to promote the adoption of digital health records in medical practice. This is part of the HITECH law and is meant to certify software according to CEHRT.
- ONC-ATCB. This is the initial certification of electronic health record technology in the United States. The certification body helps healthcare organizations implement and update their information technology.
Step 3: decide on the functionality of the system

. EMR systems usually contain personal data of patients: full name, address, age, gender, diagnoses, test results, allergies, prescribed medications, contraindications to treatment, DNA test results and other information that gives an overview of the patient's health.
. When a patient first comes to the hospital or makes an appointment, the front office needs to get their information - name, age, address, insurance company - and enter this data into the system. Some EMR software allows you to scan your driver's license and insurance cards by automatically filling in many of the required fields.
. After registering a patient in the system, you can add him to the schedule of appointments and assign him a specific doctor. Typically, scheduling tools resemble a calendar, where you can select the type of meeting, date and time, contact information, lead source
Detailed tracking of the history of diseases and their treatment, prescribed medications and contraindications. This feature increases the doctor's chances of making a correct diagnosis in a short time and making the right decision about treatment. Also, based on the many medical histories, it is possible to understand how effective the treatment is (whether medications and medical practices work).
Filling out medical records.
This is the least favorite activity among doctors in the whole world. Therefore, one of your main tasks when developing software for an EMR system is to make this process as simple and understandable as possible, as well as automate it where possible. This can be achieved with custom templates, machine learning and blockchain technologies
Integration with laboratories
. It is needed to simplify, improve and speed up the interaction between hospitals and laboratories. For example, you can implement in your EMR the function of tracking the delivery of samples to the laboratory and outputting the results directly to the system, which will give more complete control over the treatment process and eliminate errors associated with manual transfer of data from laboratory to medical records.
. Automatic appointment reminders sent to patients by email or SMS will save a lot of time and reduce the number of missed appointments. For doctors, this option is also useful, as it allows you to concentrate on treating patients and not waste time memorizing the schedule of all events and appointments.
. These are tools that track patient prescriptions
, including information about what types of treatment they are receiving now and in the past. Advanced EMR software can automatically warn that a new prescribed drug should not be taken along with the one the patient is currently taking.
. EMR management software typically includes a suite of analysis and reporting tools that provide an overview of information about patients, doctors, and the clinic as a whole.
. The electronic health record management system should also include a user interface for patients that provides them with access to the following data:
- History of visits.
- Patient record and treatment.
- Laboratory tests with results.
- Detailed hospital discharge reports.
- Prescriptions of prescribed medications (drugs).
- Online requests for renewal of prescribed medications.
- Information about whether the patient is a donor.
- Reservation of appointments with doctors, their schedule.
- Immunization, allergies, contraindications.
- Treatment costs, payments, insurance.
- Possibility of downloading your medical card.
Step 4: select the API technology stack
From a technical point of view, a user site or application consists of a client (front-end) and a server (back-end), which are connected to each other and to other services through an API (Application Programming Interface). When creating your EMR system, you need to choose which development tools and APIs you will use in your project. Here are some recommendations.
. Includes all software elements
with which end users interact: doctors and patients. This is the user interface and the interface of the EMR system. The table below lists the most commonly used development tools for the three main platforms.
. The server part of the EMR system, which works with information and corresponds to the place where the main service functions are performed and transmitted with the necessary results to the front-end component of the system. This is what the technology stack for internal EMR software development looks like:
API (Application Programming Interface)
- Programming language: Ruby (recommended), Elixir, Python, PHP, Java.
- Database servers: PostgreSQL (preferable), MySQL.
- Web frameworks: Ruby On Rails (recommended), Phoenix.
- Web servers: nginx (preferable) or Apache.
- Hosting: Amazon Web Services (AWS, EC2, S3 etc.).
. A set of software solutions for connecting external and internal interfaces, as well as integrating the necessary third-party services that extend the functionality of your platform. Different systems will require different types of APIs, depending on the focus and required functionality. The table below shows the possible services that you can use when developing your own EMR platform:
Step 5: get started developing EMR
EMR systems are complex software with very high safety and reliability requirements that can only be achieved through custom development, since WordPress and website builders simply cannot provide even minimal protection of personal data. Where to find someone who can be entrusted with such development is described in detail and with examples in the article «How to choose a developer company
When you select a developer, the EMR creation process will be like this:
- Signing a contract. At the first stage, you, as a customer and a development company, as a performer, draw up a detailed technical description of the project, indicate the timing, cost and performance indicators. When all these things are agreed, you enter them into the contract and sign it.
