The main purpose of technology is to optimize, advance, and assist in procedures and workflows for people of various professional fields. Healthcare specialists are no different in regard to counting upon new avenues.

EHR systems connect the advancements of technology with high-quality care. Their main goal is to provide convenient solutions to the potential challenges of health record management.

In this brief abstract, we will give the definition of an EHR, set its benefits, and define the core features of every EHR system.

What is an electronic health record system?

Basically, an electronic health record system (EHR) is a digital version of the paper charts. They are designed to store patients’ medical and treatment histories alongside other related details. These records can also easily be shared with authorized providers like pharmacies, laboratories, or emergency facilities.

Don’t confuse EMR vs. EHR. Essentially, an EMR — an electronic medical record — serves as an integral part of an EHR. It refers to records like diagnoses, allergies, and immunization dates. In turn, EHR is not just a record.

EHR allows all kinds of data to be manipulated, retrieved, and updated via built-in tools and procedures.

Despite the benefits of EHR systems, they were never considered perfect, especially before the Covid pandemic. It was just a source of extra work for many.

However, the pandemic switched the focus on a faster transformation of the flaws for healthcare workers to better address health issues.

So, let’s look at some constitutional benefits of a consistent EHR system, without diving into much detail.
