Scalability Considerations for Custom EHR Solutions

Amidst the rapid adoption rate of electronic health records software, custom-built EHR software has also marked its market presence. In the United States alone, almost 4 out of 5 office-based physicians have adopted electronic health records software systems.

EHRs are at the helm of the digital drive in the healthcare sector, and they are slowly entering the mainstream healthcare workflow worldwide. While most of the healthcare institutions and practices have made it evident that EHRs are beneficial for their practice, the fact is that, along with technology, healthcare practices are also evolving.

This is where the question, ‘Is my custom EHR software scalable?’ becomes crucial for healthcare practice. It is natural that Electronic Health Records are making up a larger portion of the digital healthcare infrastructure. Your healthcare practices depend heavily on it, connecting every other aspect of healthcare delivery with your practice.

And this is where most healthcare professionals who are trying to shift to digital care delivery miss the mark. The foundation of scalable EHR development is set during the development phase of custom EHR development.

EHR scalability is crucial because, over the course of time, your practice will scale, and the software should be able to handle a significant amount of load while allowing multiple users to work on it efficiently.

In this blog, let’s see how to develop a future-proof EHR by enabling EHR scalability and what factors you should keep in mind during custom EHR software development.

How to Scale a Custom EHR System?

Building a scalable custom EHR system starts long before your practice begins to grow. The foundation for future growth is established during the development phase, allowing your EHR to support more users, patient records, locations, integrations, and clinical services without requiring a complete rebuild. Here are the key steps to building a future-proof EHR system:

• Design a Modular and Scalable Architecture to support future features, specialties, and workflow enhancements.
• Plan for User Growth and Multi-Location Expansion so your EHR can accommodate more providers, departments, and facilities.
• Build Scalable Data Storage and Database Infrastructure to efficiently manage growing patient records, imaging, and connected device data.
• Leverage Cloud-Based Infrastructure for elastic resource allocation, high availability, and seamless scalability.
• Enable Interoperability and Future Integrations using standards like HL7 and FHIR to support evolving healthcare ecosystems.
• Continuously Monitor and Optimize Scalability by tracking system growth, infrastructure utilization, and changing organizational needs.

Understanding Scalability in Custom EHR Software Solution

Before diving deep into the core aspects of developing a scalable custom EHR software, let’s first understand what scalability refers to in EHR software systems.

In a nutshell, the scalability of the EHR software is the software’s ability to handle the increasing workload without compromising the performance of the software system.

Here, the increasing workload refers to the growing patient population, which is fairly natural as your patient population is bound to increase as your healthcare practice is sustained. With an increase in the patient population comes more users and the need to add new features and applications.

Custom EHR development performance can be truly scalable when its software is able to withstand the increasing workload and keep the system intact and running by avoiding system crashes and enabling smooth data flow.

But as discussed earlier, the foundation of scalable custom EHR software is laid during the development phase. What really are the considerations that we should take to achieve EHR scalability?

Well, find out more details below.

Key Scalability Considerations in Custom EHR Solutions

1. User Growth & System Expansion

To understand this aspect of healthcare practice better, let’s assume that you’ve started a specialty clinic and have developed custom EHR software for the same. Now, since there will be less inflow of patients, the software will be easily compatible with the data flow. However, as your practice grows, the number of patients and providers using the same EHR software will increase, which will require you to have a growth-ready EHR.

To ensure that your software is able to accommodate the growth in users, building a multi-tenant architecture can come in handy. This way, you can enable multiple users to access one instance of the application at the same time. Along with that, enabling role-based access control will help you safeguard the information and efficiently manage patient data for holistic healthcare delivery.

Furthermore, if you need the system to accommodate new specialties and departments, then the software needs to be flexible enough to give you enough room to add additional features and handle traffic as well.

For instance, your system should give you the ability to add new specialties, departments, and even locations in case you open a practice at a different location. This feature is exceptionally important for your practice and reveals almost everything about the scalability of a custom EHR. And this is one of the major scalability challenges in custom EHR solutions.

When your practice grows and you have to add new users to your system, your scalable custom EHR system should ensure smooth concurrent usage. This is one of the most crucial things for a multi-location practice; many users will access and use the system simultaneously. In such cases, there are high chances that the system might crash, and there might be some complications in data management.

This issue must be addressed, and concurrent usage of your system must be ensured.

2. Data Storage & Management

The inclusion of technology has provided us with crucial data on almost everything that we do on the internet. The same is the case in the healthcare industry; it is predicted that by the end of 2025, healthcare data will increase by 36%.

Some of the major contributors to this healthcare data will be from genomics, wearables, and the usage of IoT devices. This will provide you with new challenges with data volume and storage capacity.

One of the best practices for scalable EHR in terms of data storage and management is to leverage cloud-based storage like AWS or Azure. These cloud-based storage solutions offer you unlimited capacity and can be scaled to meet your needs and requirements. Along with that, implement data compression practices so that data integrity is maintained and you have enough room to store data for a prolonged period.

Another best practice for scalable EHR in terms of data storage is to archive the older data, as it offers an economic solution with regard to the cost of scalable EHR development. Also, the factor of scalability in a custom EHR majorly depends on the database performance as well. With respect to that, you should have a dedicated team to maintain the databases.

Since you will practice adding and generating more data, the volume of data will scale over time, and your system and database should be able to handle the amount of data. Top-notch database performance is the sign of a future-proof EHR system.

Leveraging Cloud-Based Infrastructure for Scalable Custom EHR Systems

If you ask any developer about their infrastructure choice for scalable software, then most likely they’ll suggest a cloud-based infrastructure. And for good reasons, you see all the software systems that have a large user base rely on cloud infrastructure, as it has a direct impact on their long-term scalability and stability.

An on-premise system fails in handling growth spikes because these databases have limited scope for scalability, and they are capacity-bound. On top of that, on-premise systems require a higher upfront investment, and every minor expansion will also require more cost; in short, it is a costly venture.

Furthermore, other limitations come in the form of operational and maintenance overhead, limited resilience to traffic spikes, physical expansion constraints, and, most concerning, long provisioning timelines. You see, due to its less elastic nature, adding new servers, storage, or even computing power to your systems can take weeks or even months.

Considering all these, cloud infrastructure is what many healthcare IT professionals choose for scalable custom EHR systems. Cloud systems give you elastic support that enables your system to function smoothly even during high-traffic spikes or for multi-location access.

Having a cloud infrastructure for scalability is like having an elastic and endless database that expands as per the needs of your system. Here’s a brief overview of the major cloud-based service providers that you can use for your custom EHR.
