EHR - Electronic Health Record System Case Study

EHR system – (electronic health record) is a software that allows doctors to view patients’ data in digital form – website or app. His or her medical history, personal information, previous visits, test results and other medical indicators and health conditions.

This industry has its origins in the 1970s when The United States Department of Veterans Affairs has launched the Decentralized Hospital Computer Program (DHCP). Prototypes of similar systems were developed earlier. Still, only this system has received access to federal resources, which allowed it to grow and evolve. It was a massive step for EHR system development and healthcare software.

Timeline of Documents

The main idea was that, in the interface, there would be a tool to view the history of patient visits, recent analyzes, and visits to the emergency. Also, the detailed view with filters by the hour, day, month, and year will be available depending on the doctor’s needs.

We came up with a timeline of the patient's history, visits, operations, medication prescriptions, and other medical indicators quickly so that doctors can quickly familiarize themselves with the entire history of the disease or restore any time slot by the minute.

Heat Map of Diagnoses

Initially, we wanted to display this data in a chart in which it would be easy for the doctor to identify the patient’s main problems quickly.

The stakeholder has proposed implementing the visualization with the help of the human body, which will allow doctors to quickly understand which system the problem is and its priority.

The Flexibility of System

The stakeholder gave us a task for a block that was supposed to solve the problem of comparing a large number of files. Cause on the original version of the platform, the best thing that could be done was to print all the data and compare it by hanging it on a board or wall.

We came up with a panel that collects all the documents for comparison. This panel makes it possible to save documents separately and filter them by any parameters.

Lab Tests

As part of the work on EHR systems, it is periodically necessary to compare laboratory tests. Doctors could need to look at individual results, decide how they changed during treatment, and evaluate general indicators during the emergency.

The stakeholder has initiated rethinking the lab analysis page to be viewed quickly and easily within the interface.
