The healthcare industry is on a constant lookout for digital solutions to conduct the financial, administrative, and clinical operations of a hospital. These days, these are largely carried out by means of a set of informatics tools, collectively known as Hospital Information Systems (HIS). In addition to a patient's health information, inventory and personnel data are also stored, managed, and transmitted across a HIS.
Electronic Medical Records (EMR), and Electronic Health Records (EHR), nurses reports, diagnostics, doctor's prescriptions, equipment, emergency transportation allocation - the end-to-end management of all these functions of a healthcare organization can be carried out over a reliable and high-fidelity HIS.
In this article, we will first dissect how HIS software works, and define the various components of such a software system. We will go on to further discuss the various types of HIS implemented in hospital systems today.
What is a Hospital Information System and How does it Work?
Everyone involved in a healthcare organizational setup from patients, to clinicians to public health officials interacts with a HIS. The HIS involves a bunch of subsystems handling data related to the activities of providers and healthcare organizations. In addition to a hospital's operational management, HIS also takes care of other aspects such as supporting healthcare policy decisions.
Through a secure and high-fidelity hospital intranet, a HIS operates online and lives on top of the already existing hospital network. Based on diagnoses for various illnesses, physician recommendations, past patient history, and trends, the database servers of the HIS store relevant health information.
A HIS is used for setting up online appointments with doctors, passing on nurse reports from one shift to the next, as well as other activities. It streamlines the storing and retrieval of all healthcare data and also manages payment invoices and billing cycles for patients.
Components Of Hospital Information Systems
A hospital's HIS is a conglomeration of several specialized sub-systems that manage different functions of a healthcare organization's functioning. The main components that a HIS can be divided into are the following:
1)Core Management: The core system of the hospital or the hospital management system is an independent or cloud-based medical management framework. This system captures and integrates the day-to-day activities of each department of the hospital system.
2)Financial Software: Chief financial officers and those responsible for the revenue cycle management carry out their management and strategic planning through this software component. SaaS accounting and financial management plug-ins often interlink to form the overall financial management system. With proper monitoring of the healthcare organization's revenue cycle, the bottom line can be enhanced and resources can be freed up to spend on value-enhancing operations.
3)Personnel/ERP: Patient and employee management tools are together taken care of the personnel management capabilities of HIS. These systems facilitate transparent communication, resource allocation, and scheduling between patients and medical staff across multiple facilities and departments. The major suppliers of ERP systems, in general, are strategically considering the potential of healthcare to be a relatively new and fast-growing market.
4)Medical Documentation: While EHR and EMR systems track patient appointments, care notes, and financial information, a dedicated documentation framework must be in place in the overall HIS. This helps ensure that all high-priority documents, from patient records, personnel details, inventory, hospital finances, etc. are maintained across secure encrypted portals with proper access control.
5)Asset Tracking: Asset tracking or medical inventory management systems enable hospital staff to monitor inventory across the inventory lifecycle right from purchase to compensation. When an item in the inventory, be it pharmaceuticals or surgical tools, is on the brink of expiry, it can be replenished or stocked back up. It is a means to ensure that the best practices are followed in terms of inventory maintenance.
6)Medical Transportation Management: It is required by US federal law that the least costly type of transportation takes patients to their relevant medical appointments. This is true for both emergency and non-emergency medical transportation and the tracking, maintenance, and allocation of these vehicles is an essential functional component of HIS.
Types Of Hospital Information Systems
Any Hospital Information System, or HIS, is crucial in improving the healthcare organization's bottom line as well as providing more holistic and reliable patient care. A National Library Of Medicine report revealed that US healthcare organizations were able to save about $ 50,000 per every general physician employed on operating expenses. In general, there are several iterations of the traditional digital HIS, but the following are some of the most popular ones:
1)EHR and EMR: EHR or Electronic Health Record is an electronic document that stores all the patient data and information. EHR allows seamless transfer of patient data between various organizations. Typically EHR data includes data such as patient information, appointments, family and case history, allergies, data about any existing diseases, hospitalization records, immunization status, and records of surgeries.
EHR offers several benefits to healthcare providers and patients alike, let's have a look at some:
- Seamless data transfer: One of the fundamental advantages of EHR systems is that they provide a secure and seamless channel for vulnerable data transfer by centralizing patient information.
- Enhanced data storage and management: The centralized structure of EHR systems allows healthcare professionals to eliminate the need for physical storage space and the challenges associated with managing and retrieving paper records from different locations. Additionally, patient information is structured and organized in a standardized format, making it easier to categorize and retrieve specific types of data, such as lab results, medications, or medical history.
- Reduced redundancy: The EHR data allows healthcare providers to quickly check if a test or diagnostic procedure has already been conducted. This helps in avoiding unnecessary duplicate tests, reducing both costs and redundancy in medical procedures.
- Efficient workflow: By reducing paperwork and streamlining administrative processes EHR systems provide efficient workflow
EMR or Electronic Medical Records is a system designed to store patient data. However, unlike EHRs, EMRs are not designed to transfer patient information to other departments and healthcare organizations. These systems are only used in a single healthcare organization and not between multiple healthcare organizations.
Let’s have a look at some of the advantages of the EMR system:
- Centralized patient records: The EMR system offers a centralized framework to store crucial patient data such as medical history, medications, allergies, and test results in one accessible location.
- Enhanced patient care and safety: Easy access to patient records and history allows healthcare providers to offer better patient care. The centralized framework allows everyone in the healthcare organizations to access the information when required.
- Remote monitoring and telehealth integration: EMRs enable remote monitoring of patient's health conditions and integrate it with telehealth solutions. This is especially valuable for managing chronic conditions and providing care to patients in remote or underserved areas.
EHR and EMR can also exist independently and as components of a large-scale HIS. They maintain systemized collections of patient and health information in a digital format. Regardless of the type of healthcare setup, care setting, and capacity of a healthcare organization, these systems are implemented for patient information sharing. Additionally, they also help with easier consolidation of patient information to prepare charts and reports about general trends and patient statistics.
2)Clinical Information Systems: Clinical Information Systems (CIS) are digital solutions meant for automating the electronic data collection from monitors, ventilators, infusion pumps, filtration equipment, cardiac assist devices, and so on that comprise the everyday modern clinic of today. These types of systems can import or export data between medical instruments and also allow the free flow of information across systems.

These types of systems can import or export data between medical instruments and also allow the free flow of information across systems.
Being an extensive framework, CIS includes different components let’s have a brief look at these:
- Lab, Pharmacy, and Diagnostic Systems:
Laboratory management systems, pharmacy management systems, and diagnostic management systems aid healthcare providers in efficiently handling various clinical responsibilities, including the upkeep of laboratory data, maintenance of medication and prescription records, and the determination of diagnoses based on laboratory results. - Document Management:
Document management systems simplify paperwork for healthcare providers and clinics, encompassing the organization of patient diagnostics, case management, and treatment actions. - Clinical Decision Support:
The clinical decision support system leverages data gathered from electronic medical records (EMR) to deliver hospitals, clinic staff, patients, and other stakeholders with personalized information and insights. This information is intelligently filtered and presented at relevant times, aiming to improve overall health and healthcare outcomes. - Administrative Data:
Administrative data plays a crucial role in monitoring the patient's activities in the clinic. This encompasses pertinent information like patient admission details, discharge and transfer records, bed allocations, as well as schedules for surgical and medical procedures. - Communication Support:
Support for communication offers clinical information systems a seamless channel to facilitate communication among patients, clinic staff, and doctors. This aids in managing the continuity of patient care during transitions between multiple clinicians.
3)Practice Management Software: A practice management system is a type of software that enhances practice efficiency, professional satisfaction for doctors, and streamlined delivery of patient care. These types of software systems usually manage the registration, scheduling, patient tracking, accounting, and reporting across a single managed workflow for all departments. A single platform is then enabled to collect payments on all patient accounts.
Let's have a look at some of the key features of Practice Management Software:
- Online Scheduling
An online appointment scheduling feature allows flexibility and ease to both clinic staff and patients. It provides an easily maintained calendar that helps healthcare providers to plan their next steps in advance. - Automated Reminders
A booked appointment never always means an attended one, automated reminders allow hospitals to keep track of their patients and remind them of upcoming appointments. - Payments
PMS incorporates payment portals for seamless transactions between the hospital and patients. The inclusion of flexible payment methods enables patients to view their invoices and make payments without navigating through multiple windows. - Appointment Profiles
Utilizing appointment profile templates enables hospitals to pre-determine the appropriate duration for appointments in their schedule, taking into account both the type of diagnosis and the specific patient. This optimization ensures that the hospital schedules an appropriate amount of time, avoiding overbooking or underutilizing calendar slots. - Real-Time Eligibility Checks
Practice Management Software simplifies the verification of insurance eligibility and paperwork for clinical staff. It empowers staff to review patients' insurance details, including deductibles, co-payments, and co-insurance. For certain treatments that require pre-approval, the practice management software should offer immediate access to insurance companies.
4)Clinical Decision Support Systems: Clinical decision support tools are developed to assimilate large volumes of patient and treatment-related data. These systems then process this data, categorize them, and automate the suggestion of the next possible course of action for patients' treatment and diagnosis. They provide prompts and reminders to assist in the implementation of evidence-based clinical guidelines at care delivery.
There are mainly two types of Clinical Decision Support Systems (CDSS), let’s have a look at these below:
- Knowledge-Based CDSS
The Knowledge-based CDSS employs an inference engine to apply rules to patient data and subsequently presents the results. This system typically comprises a data repository, an inference engine, and a communication mechanism, often functioning based on if-then rules. - Non-knowledge Based CDSS
CDSS which is not knowledge-based utilizes machine learning to analyze clinical data. An illustration of such a system is an artificial neural network, which learns to execute specific tasks by studying particular examples, typically without being explicitly programmed with if-then statements or other task-specific rules.
5)Patient Portals: Patient portals enable patients to retrieve their personal health information, including appointments, medications, prescriptions, and lab results, in an online platform. Various patient portals also facilitate direct communication with healthcare providers, permit prescription refill requests, and offer the capability to schedule appointments.
Generally, patient portals can be classified into two groups:
- Integrated Patient Portals
Included within comprehensive healthcare solutions like EHR or PMS (Practice Management System), integrated patient portals facilitate swift and secure data exchange among different modules in the system. Despite this, they are limited in flexibility and customization options. - Standalone Patient Portals
Tailored to meet specific clinic or client requirements, standalone patient portals can be custom-made applications. These applications may operate independently outside other healthcare systems, such as EHR or CIS within an organization, or they can be seamlessly integrated with them.
