Legacy systems in healthcare are not rare. This phenomenon is pretty widespread among healthcare providers for several reasons…

  • Healthcare is a conservative industry in which users prefer to minimize experimentation with new technologies in favor of reliable, battle-tested systems they have used successfully for a long time. 
  • Many healthcare organizations don’t possess sufficient IT professional teams to manage their software-upgrading strategies proactively.
  • Certain medical functionalities do not require frequent updates—for example, patient data fields in EMR/EHR management systems are one of the health tech instances that rarely change. 
  • Certain systems are so deeply ingrained in organizational workflows and culture, it feels like replacing them could endanger the normal flow of business operations…
The Reasons Why Healthcare Organizations Avoid Upgrading Legacy Systems | TATEEDA GLOBAL

How Acute Is the Issue with Legacy Software in Medical Practices?

Persistent use of inefficient or flawed health legacy systems is a shockingly pressing problem among American medical organizations like hospitals and medical offices.

A team of IT researchers recently discovered that almost 83% of healthcare IoT devices in the United States are driven by outdated, unsupported operating systems. Decommissioned, insecure, unpatched, and vulnerable to exploits and cybercrime attempts, they keep around 98% of sensitive medical data transactions exposed or poorly encrypted. 

When it comes to legacy software systems and perspectives on their transformation or replacement, there exists only one golden rule: Reluctance to upgrading legacy systems in healthcare will surely do more harm than good. It’s better to opt for a long-term modernization strategy and follow a maintenance plan for healthcare applications and IT environments.

How to Know It’s Time to Modernize Your Healthcare Software Technology (Checklist)

How will you know that legacy system modernization in healthcare is completely necessary for your organization? Look for several negative signs that indicate outdated software systems while they are operating in clinical or administrative workflows. If you spot several of these indicators, we recommend that you look at legacy software upgrade options with a skilled IT consultant. 

Let’s see what these red flags would look like… 

🚩 Limited Healthcare Software Functionality 

Legacy systems are not designed to handle all capabilities offered by the modern healthcare technology landscape. This includes the following flaws…

  • The number of document types or data formats your software system accepts is very limited (and this number will grow yearly.)
  • Integration or data exchange with other systems is impossible or seriously limited because of technical restrictions that cannot be quickly fixed. 
  • The user suggestion log for new features is growing without a means for implementation.
  • The healthcare solution is platform-dependent, meaning it cannot run anywhere outside of an outdated OS environment (like 32-bit platforms, including Windows XP or Windows 7.) 
  • There is still a considerable number of manual operations and workflows that should be combined with automated or semi-automated application routines.  
  • Incompatibilities with or dependencies upon certain hardware components, like screens of a specific type or resolution. 
  • The legacy application is not ready for cloud transformation and remains totally dependent on local hardware infrastructure.   

❌ Malfunctions and Tech Incompetence

Healthcare legacy system modernization will become obligatory when your software product demonstrates worsening levels of technical performance. For example:

  • Software crashes frequently and/or replicates glitches.
  • It takes progressively longer to perform even basic software operations (reduced productivity is obvious and badly affects user experience.) 
  • Software performance is deficient, slow, and irritates medical staff, which is reflected in regular user reports/feedback.  
  • Software misinterprets regular commands and authorized user activities. 
  • Cases of data breach or inconsistency are detected by staff members. 
  • Clinical staff reports that software has become more difficult or inconvenient to operate for a variety of reasons.
  • Qualified software performance tests and/or software execution logs (analyzed by IT professionals) show unsatisfactory results and conditions.   

🚫 The Healthcare Product Is Abandoned by Its Vendor

Medical application users are not always aware of their product status. Sometimes, it appears that a vendor is no longer active or has abandoned the product. In this case, it’s highly recommended that legacy healthcare software be upgraded or replaced by an up-to-date solution if…

  • Your product version is out of date according to the vendor website.
  • The vendor has clearly stated they will no longer release new versions, provide support, or offer patches for your product. 
  • The vendor offers medical data portability to help you move to their newer products and recommends switching to alternative versions/applications. 
  • The vendor website has been inaccessible for a long period of time or you directly receive their out-of-business notification. 
  • No fresh versions or application updates have been released for a long time (between 2 to 5 years on average).

6 Modernization Strategies: The Most Popular Legacy Medical System Upgrade Methods

What medical practice and hospital legacy system modernization approaches are available out there? 

  1. Encapsulation: Reassembling software modules with programmatic encapsulation of deeper application components (like medical databases) to isolate them and then “wrapping” with newer interfaces and functionalities via APIs and other applicable software engineering methods. This approach allows for the seamless integration of older and newer system components. 
  2. Rehosting: Redeploying your legacy healthcare application to another platform or infrastructure: physical hardware, virtual settings, or cloud technology, for example, without deep revision of its code sources, features, and capabilities. 
  3. Refactoring: Enhancing and optimizing current code to eliminate technical issues, loopholes, and inefficiencies. This method is a great option, but it’s applicable to a limited group of legacy systems in healthcare. Refactoring strategy is predominantly used with open-source or custom software solutions. Refactoring can be done by the original custom product vendors or by third-party developers if the proper software documentation is available.  
  4. Rearchitecting: Almost complete reconceptualization of a legacy product, including changing its core tasks and functionalities. This approach usually requires shifting to different technologies and platforms along with deep modernization of application architecture, which enables new capabilities. 
  5. Rebuilding: The product scope and key specifications of a legacy application are predominantly left intact; however, the sources are rewritten from scratch to implement newer programming languages, faster processing engines, and more flexible platforms.
  6. Replacing: Obsolete healthcare applications are retired completely and replaced by newer solutions. In the context of this strategy, the main considerations include selecting an appropriate alternative and migrating data correctly. This approach may include either the full-cycle development of a new application or a ready-made solution.
