Role of Order Entry System in Healthcare

In today's fast-paced healthcare environment, accuracy and efficiency are paramount. Traditionally, physician orders for medications, tests, and procedures relied on paper forms, phone calls, and even faxes. This system, while familiar, was prone to errors and delays. Enter the Order Entry System (OES), a technological marvel that has transformed how healthcare providers deliver care.


This blog post will delve into the critical role Order Entry Systems play in modern healthcare. So, whether you're a healthcare professional or simply curious about the inner workings of the medical field, keep reading to discover how Order Entry Systems are revolutionizing healthcare!



1. Overview of Order Entry System



An Order Entry System in healthcare is a specialized software platform that manages the creation, transmission, and tracking of medical orders issued by physicians. These orders can include tests, treatments, medications, and other healthcare services that need to be carried out by medical staff and technicians. 


The system ensures that these orders are accurately communicated to the appropriate departments, monitors the execution and results of the orders, and interfaces with billing systems to ensure correct and timely invoicing for the services rendered.


Additionally, the system facilitates reconciliation processes to verify that all ordered and performed services are properly recorded and billed, enhancing overall efficiency and accuracy in healthcare delivery.

Types of Order


In the healthcare Order Entry system, orders can be categorized into three main groups based on their nature and requirements. The first group includes orders that require medical materials, such as laboratory tests, imaging studies, medication injections, and intravenous drug administration. These orders necessitate the use of specific medical equipment and supplies to perform the procedures and services.


The second group comprises orders that do not require medical materials, such as consultations, observations, and treatments. These orders typically involve monitoring and caring for patients without the need for special medical tools or materials.


The third group consists of orders that describe the execution, including conditions of execution, speed, duration, diagnosis, and contraindications. These orders provide specific details on how and under what conditions the medical actions should be carried out, ensuring they are performed safely and effectively.


Additionally, orders may include instructions for actions before and after execution, such as supplementary information, necessary actions before and after performing medical activities, and patient contact protocols. This information ensures that all medical procedures are conducted seamlessly and comprehensively, while also safeguarding the health and safety of the patients.

2. How Order Entry System works

Order Entry has a close relationship with departmental systems. It sends order information and receives execution details as well as results from the departmental systems. This execution information and results are then transmitted by the Order Entry system to the billing system for calculating hospital fees.

In the medical treatment and examination 


The Order Entry system plays a crucial role in the medical examination process, optimizing and improving operational efficiency. Previously, copying and transmitting treatment requests to multiple departments was time-consuming and prone to information errors due to copying mistakes. This led to risks of incorrect treatment requests or patient mix-ups, as well as wasting time printing and transferring documents, causing doctors to spend more time processing information and increasing the likelihood of confusion.


The Order Entry system addresses these limitations by allowing doctors to quickly and accurately transmit treatment requests to various departments with just one data entry. The system also accurately identifies patients using IDs, barcodes, or wristbands, ensuring safety and minimizing the risk of mix-ups. Examination and treatment results are promptly communicated, enabling doctors to easily draw conclusions.


Furthermore, the Order Entry system integrates with Electronic Medical Records (EMR), reflecting detailed processes and medical examination results. This not only improves the efficiency of doctors' work but also enhances the quality of patient care by ensuring that all information is recorded and accessed accurately and timely.


In healthcare insurance


In the realm of healthcare insurance, the Order Entry system serves several critical functions:


Documentation and Compliance

It gathers and records physician directives and treatment details, ensuring adherence to insurance treatment protocols. This ensures that all treatments and procedures documented align with the guidelines set forth by the insurance provider.


Integration with Billing and Accounting

The system is closely linked with medical billing processes and healthcare accounting systems. This integration ensures that all medical services rendered are accurately documented and billed according to the specific requirements of the insurance coverage.


Data Fields Customization

The fields within the Order Entry system are meticulously tailored to capture the necessary details for medical expense reimbursement claims. This customization ensures that all pertinent information, including treatment specifics and procedural documentation, is accurately recorded and readily accessible for processing reimbursement requests.




In summary, the Order Entry System is indispensable in modern healthcare, streamlining medical orders from creation to execution with precision. It plays a crucial role in enhancing treatment and examination processes by ensuring swift and accurate communication across departments. In healthcare insurance, it facilitates compliance with treatment protocols and streamlines reimbursement procedures, integrating seamlessly with billing systems for efficient financial management. As healthcare evolves, the Order Entry System continues to be a cornerstone in delivering effective, coordinated care and optimizing operational efficiency across healthcare facilities.
