How IT Systems Run the Modern Hospital
Hospital's Digital Landscape: An Overview of IT Systems
For many of us, visiting a hospital can be a stressful and overwhelming experience.
Long queues at billing counters, overcrowded waiting rooms, and a sea of patients seeking assistance, overwhelmed staff shuttling between cases – this is the scene that often greets us upon entering a hospital.
Behind the scenes, support staff handle billing, manage equipment, and ensure supplies – all part of an intricate web supporting patient care.
In my previous post, I spoke about how running a hospital is like running a company and you see why.
Like large organizations, hospitals require interconnected operations – from treatment to supply chain, emergency response to billing – all centered around the patient.
This post explores the systems involved in hospital and patient workflows. While hospitals seem monolithic, housing all patient information, the reality is an intricate network of systems operating behind the scenes.
Take 1: The Patient’s Perspective
Have a look at this illustration.
Looking at this workflow, how do you imagine these being handled through the hospital's systems?
In the past, hospitals relied on paper charts, fax machines, and manual processes for everything from appointments to billing. This led to inefficiencies and errors.
Fortunately, modern IT systems have revolutionized healthcare by digitizing workflows and improving communication.
Take 2: The Health IT perspective
Let us go back to our patient Uma and look at the same scenario but now, let's relook at this workflow with the Health IT systems that are in play while our patient Uma goes through this journey.
Each system plays a specific role in the patient's journey, ensuring a seamless healthcare experience. The term "Health IT" encompasses this wide range of technologies and solutions.
Two key terms that often emerge here are EMR and HIS.
While "EMR" (Electronic Medical Records) and "HIS" (Hospital Information Systems) may seem interchangeable, they play distinct roles in managing patient data and hospital operations.
The journey towards digitalizing patient health records began with Electronic Medical Records (EMRs), transitioning from paper-based systems to digital repositories.
As interoperability became crucial, Electronic Health Records (EHRs) emerged, enabling seamless data exchange across healthcare settings.
Concurrently, Hospital Information Systems (HIS) evolved to manage broader hospital operations, integrating patient care, administration, and finance.
While these terms may seem interchangeable, modern healthcare informatics has seen the rise of integrated solutions, blurring distinctions between EMR, EHR, and HIS functionalities.
However, the effectiveness of these systems lies in their seamless integration with diverse healthcare systems, both internal and external.
Cataloging Hospital IT Solutions
Let's delve a little deeper into this intricate web of healthcare systems and look at the healthcare IT applications and solutions that form a piece of this puzzle.
It's essential to acknowledge several key points here:
This compilation does not encompass all the software and systems prevalent in the hospital domain.
Each of these systems possesses intricate complexities within their respective domains, managing substantial datasets and workflows.
The crux lies in the interactions among these systems—the integration points. Consider the scenario where Uma's lab results fail to transfer from the LIS (Lab Information System) to the EMR, or worse, if another patient's reports get inadvertently shared instead.
Integration among these systems constitutes a vast and critical domain within health IT. However, delving into this topic exceeds the scope of this discussion; perhaps it warrants another dedicated post.
Perhaps, acknowledging these integration challenges and the imperative to have a more cohesive system, many HIS and EMR vendors now incorporate or integrate most of these systems into their software offerings.
Have a look at these links which talk about some of the EMR solutions in the market and what they offer - EPIC EMR, Philips EMR, IQVIA
Health IT - A necessity?
Now that we've examined the array of software solutions and systems tailored to the hospital landscape, one might wonder: Are all these IT systems necessary for running a hospital?
The answer isn't a one-size-fits-all.
A small hospital with a staff of 15-20 may find a Human Resource Management System (HRMS) unnecessary.
A local town hospital serving a limited patient base may not see the benefits of a Customer Relationship Management (CRM) system.
Conversely, a hospital network spanning multiple units, offering diverse specialties, and aiming for expansion could significantly benefit from implementing most of these systems.
The appropriateness of employing these systems hinges on factors such as hospital size, the spectrum of specialties it covers, and the specific challenges it aims to address.
There are many hospitals even now that offer great patient care without all these complex systems.
Navigating the Pros and Cons of Hospital IT
Furthermore, do these systems automatically enhance patient treatment and streamline operations?
While health IT solutions offer tremendous potential, they are not a panacea. It depends on effectively hospitals implement and incorporate these systems in their processes.
That said, these systems are not without their challenges.
Clunky software can disrupt workflows and make data entry burdensome. Integrating all these systems can be tricky. And as healthcare IT becomes increasingly interconnected, cyberattacks and data breaches pose a significant threat.
Yet, the benefits are undeniable:
Diagnostic imaging technologies like MRI and CT scans now produce high-definition digital images equipped with precision tools for enhanced diagnosis and treatment planning.
Clinical decision support solutions leverage data from Electronic Health Records (EHRs) and other sources to monitor patient status, identify potential risks or complications, and facilitate care coordination.
Telemedicine facilitates remote consultations, thereby improving access to care for individuals in remote areas or with mobility limitations.
Laparoscopic and robotic surgery utilize high-definition cameras and miniature instruments, enabling smaller incisions, quicker recovery times, and reduced patient discomfort.
Unlocking the potential
The power of it is in bringing all of it together.
EMRs and HIS integrated with all these different system creates a powerful combination. Hospitals have access to a wealth of data, both clinical and operational.
While the primary goal is to make it all work together seamlessly, once done it can offer a spectrum of ways in which hospitals can utilize this data to draw insights about their operations and offer better care.
By analyzing patient medical histories, treatment outcomes (from EMR), lab results (from LIS), and imaging data (from PACS), predictive models can be developed to offer personalized treatment recommendations and identify potential risks or complications.
Examination of patient admission/discharge histories (from EMR) enables hospitals to anticipate readmissions or adverse events, facilitating preventive measures and optimizing resource allocation.
Insights gleaned from billing data, reimbursement patterns, and cost structures aid in optimizing revenue cycle management and identifying avenues for cost savings.
Monitoring supply chain data (from SCM) and inventory levels (from Pharmacy systems) allows for procurement optimization, minimizing wastage and stockouts.
These examples merely scratch the surface of the possibilities.
As technology continues to advance, its integration into healthcare systems becomes increasingly inevitable.
For those in the world of health IT, comprehending the broader landscape is imperative.
Understanding where our solutions fit into the grand scheme enables us to develop more tailored and effective solutions.
And once we are familiar with the space we are dealing with, we could also better identify opportunities for improvement and pave the way for innovative solutions to address future challenges more adeptly.
So, I hope that this post has shed some light on the intricacies of healthcare systems, including EMRs and HIS, and helped to understand and better navigate the complex world of hospital management.
