What is an EHR? And Why Should You Care?

 What is an EHR? And Why Should You Care?

Imagine you’re rushed to the emergency room, miles away from your primary physician. The doctor would usually start by asking you about your allergies, medications, and medical history. But you can’t remember everything, and your medical records are far away. Scary, right?

This is where Electronic Health Records (EHRs) might be your lifesaver.

But before we dive in, let’s acknowledge the elephant in the room: why should you care?

Statistics paint a compelling picture:

  • According to a study by HIMSS Analytics, 90% of patients with access to their EHRs report feeling more engaged in their care.

The above stats might give you a brief idea that EHR is already advantageous for patients as well as providers using it for better outcomes.

Now let’s explore what EHR is exactly, the key components of the EHR system, and how it works. Moreover, we will discuss the benefits of EHR for both patients and providers. In addition to that, there are challenges in EHR implementation and the future of EHR systems.

EHR Defined

EHR-Defined-1024x557 What is an EHR? And Why Should You Care?

Electronic health records, or EHRs, are digitized patient documents. They are like complete and organized electronic folders that contain a lot of information about a person’s medical history.

EHRs store a lot of patient health information. From basic information such as demographics and personal history to more complex information such as laboratory results and diagnostic imaging.

It is a go-to solution for all health-related consultations and outcomes. Healthcare professionals can obtain information about a patient’s past medical history, surgeries, diagnosis, medications, and even notes from different providers.

The second most important aspect of an EHR is accessibility. Health records can be obtained from a variety of healthcare providers and facilities. So, whether the patient is at their family doctor, a primary care physician, or even in an emergency room, they can pull up their EHR to get a comprehensive view of their health.

Key Components of EHR

Let’s take a look at the key components of EHR:-

Key-Components-of-EHR-1024x557 What is an EHR? And Why Should You Care?

1. Patient Demographics and History

Patient demographics and history are an integral part of the EHR. This includes personal information, contact information, and timelines of the patient’s health events.

2. Clinical Records and Documentation

The clinical records and documentation section contains detailed information from the healthcare practitioner. It’s like a virtual diary of patient medical visits, recording symptoms, treatment, and progress.

3. Drugs and Allergies

EHRs keep a track record of all prescriptions and any allergies the patient may have. This is important to avoid harmful drug interactions. A study by the Journal of the American Medical Association found a 50% reduction in medication errors in hospitals using EHRs.

4. Laboratory Results and Diagnostic Imaging

All patient test results, from blood reports to X-rays, are stored in EHR. It gives providers a comprehensive view of a patient’s health status.

How do EHRs Work?

How-do-EHRs-Work-1024x427 What is an EHR? And Why Should You Care?

EHRs operate through a digital healthcare ecosystem that facilitates patient data management. Here’s the breakdown:

Data Entry:

  • Initial Data: Patients or providers enter demographics, medical history, allergies, immunizations, medications, etc.

  • Encounter Notes: Doctors record consultations, diagnoses, treatment plans, progress notes, and such information electronically.

  • External Sources: Laboratory exam results, radiology reports, pharmacy notes, and others are all automatically fused through interfaces.


  • Secure servers standardize the format in which they store information, thereby ensuring its integrity and accessibility.

  • Access controls manage who can view and change data depending on the authorization levels.

  • Providers are able to get a patient’s entire medical history in a moment without any regard for where the information comes from.

  • Patients can frequently log in to patient portals, see summaries and lab results, and talk with their providers.


  • Interoperability standards enable authorized providers to exchange data in a secure way between various electronic health systems.

  • This simplifies inter-specialty coordination, emergency treatment, and referrals.
