Legacy systems in healthcare are old software and hardware that handle important administrative or medical tasks but no longer get support because they are outdated. Recent data shows that about 73% of healthcare groups are at risk of patient data leaks because of these old systems. Many rely on people inside the organization—almost 94%—who have wide access, which increases the chance of data breaches. More than 40% of data breaches in healthcare come from these insiders.
In addition, U.S. hospitals spend around $8.3 billion each year to keep legacy systems running. Old technology not only costs a lot but also wastes doctors’ and nurses’ time. Communication delays in healthcare often average about 45 minutes. This delay can hurt patient care and affect how smoothly services are delivered.
Legacy systems often cause “technical debt.” This happens when problems build up due to old code and infrastructure. It makes system updates harder, lowers how well hospitals follow rules like HIPAA, and limits the ability to add new tools. Hospital managers sometimes struggle to start system changes because their staff may not have the technical skills needed to safely move important data and workflows.
Chuck Young, from the U.S. Government Accountability Office, says that keeping legacy systems means known security problems and rising costs. This problem is made worse when leaders or IT staff worry about losing data or causing trouble during the switch.
With rising cyber threats and stricter rules, using old systems is risky for healthcare groups across the country. For instance, the MOVEit file transfer hack affected over 600 clients recently, many in healthcare. This shows the urgent need to boost cybersecurity.
Moving to new cloud-based systems or Software-as-a-Service (SaaS) brings several benefits. New systems can grow easily with patient numbers, follow data security rules better, and make communication faster in medical tasks. Still, moving to new systems is hard because of technical challenges, changes in habits, and costs.
Hospitals that wait to upgrade face rising costs and risks. Brian Evans from Impact Advisors says old ERP systems waste resources, increase ransomware risks, and lower worker satisfaction. Healthcare workers want tools that are easy to use, like those they have outside work. Old platforms hurt hiring and keeping staff, which is already hard in the current job market.
Ryan Moore from Impact Advisors suggests healthcare groups make clear plans for migration. This plan should include picking vendors, involving all players, and setting real return on investment (ROI) goals. Even if the cost to move to cloud-based systems is high at first, keeping old software may cost more over time, both money-wise and in quality of care.
Moving systems to the cloud is seen as important to improve efficiency, security, and connection between systems in healthcare. Cloud migration helps centralize data, handle busy times, and use new technologies like artificial intelligence (AI) and big data.
Healthcare groups can use different methods to move to the cloud:
Each method works best depending on how old the system is, how complex it is, and how important the tasks are. For example, HealthAsyst moved an old Windows practice system to Microsoft Azure’s cloud. This cut infrastructure costs by half and made reporting three times faster. They also added mobile scheduling that helped both staff and patients.
Challenges when moving to cloud include missing documents for old apps, complex code, and old designs that limit flexibility. On top of that, workers might resist change or lack skills like DevOps, containerization, and cybersecurity. Training and support are needed to help teams adjust.
Cloud costs can change, especially when systems scale automatically during busy times. It’s important to use tools to track spending, pick reserved cloud resources if possible, and plan workloads to avoid surprises.
Using hybrid or multi-cloud setups can help healthcare groups follow rules about where data is stored, increase reliability by spreading workloads, and keep systems running during outages.
One way to make modernizing old systems easier is by using Application Programming Interfaces (APIs). Sensedia, a technology company for healthcare, offers API platforms that link hospitals, pharmacies, clinics, and labs together.
By wrapping old system features with secure APIs, healthcare groups can share data safely between systems. This helps different platforms work together and allows migration to happen step-by-step without stopping daily tasks. Microservices break big systems into smaller parts that can be updated separately. This helps fix problems faster and lets new features come out sooner.
Managing APIs is very important to keep data safe, follow rules, and keep systems stable during migration. Using multiple API gateways lets organizations control access better in complex setups and lowers risks from having too many APIs.
Artificial intelligence (AI) and automation are becoming key in modern healthcare IT, especially for dealing with old systems. AI can speed up moving systems by automating code updates and data changes. This lowers manual mistakes and shortens project timelines. For example, mLogica’s LIBER*M tool uses AI to convert old mainframe code like COBOL into modern languages such as Java. It also moves databases from Db2 to cloud-friendly PostgreSQL. This tool works with the main cloud providers like AWS, Google Cloud, Azure, and Oracle OCI.
After migration, AI also helps clinical and office workflows. AI data analysis can improve predictions about patient care, help manage resources, and guide decisions. Automating workflows reduces repeat tasks, improves communication among care teams, and cuts down patient wait times.
Healthcare teams that use DevOps with AI tools can keep improving features while making sure systems stay safe and reliable. AI migration tools also include security models that protect cloud systems replacing old, risky setups.
Early projects show that proving the value of AI and automation can help IT staff who are nervous about changing old processes.
A big challenge in moving old healthcare systems is that staff often lack skills in new technologies. Tony Jaros, CEO of Legacy Data Access, says that old systems need special knowledge that only experienced IT workers have. Newer employees may avoid working on old platforms because they fear causing mistakes or losing data.
Healthcare leaders need to train employees on cloud technology, container platforms like Kubernetes, DevOps, security, and automation tools. Change management should encourage teamwork and create advocates to support migration projects.
Building a culture of ongoing learning is important because healthcare technology changes fast. This attitude can help staff move from old systems to flexible, scalable new ones.
Cost is a major issue for hospitals and medical groups in the U.S. The upfront money needed to migrate is often high but must be weighed against ongoing costs to run old systems, security risks, and lost efficiency.
Using a phased migration lets organizations spread out their spending and reduce downtime. They should set clear goals, pick vendors with healthcare experience, and involve all groups—doctors, office staff, IT—from the start.
Realistic expectations for return on investment matter. Improvements like better doctor productivity, shorter patient wait times, and stronger compliance might show up in months. Cost savings tend to occur over several years.
Healthcare leaders, IT managers, and practice owners in the U.S. face many difficulties when moving from old to modern cloud systems. Keeping outdated software and hardware risks data leaks, slows operations, raises costs, and limits progress. This affects patient care and how well organizations work.
Cloud migration combined with APIs, microservices, and AI-driven automation offers a way to update old infrastructure. Filling workforce skill gaps, managing costs carefully, and involving all groups are important steps in this process.
Health organizations that follow careful, step-by-step migration plans can improve safety, efficiency, and patient results while getting ready for future challenges. Updating old IT systems is now necessary to keep high-quality healthcare services in the United States.
Legacy systems are outdated computing software, hardware, or data systems that are no longer supported by the manufacturer, leading to vulnerabilities and potential cybersecurity threats.
They expose sensitive patient data to cybercriminals due to lack of updates, maintenance, and known security vulnerabilities, making them easier targets.
Approximately 73% of organizations still face the risk of patient data exposure due to legacy systems.
Reliance on legacy systems incurs significant costs—estimated at $8.3 billion annually for US hospitals—due to outages and inefficiencies.
They can delay communication processes, resulting in approximately 45 minutes of communication delays, ultimately impacting patient care.
Technical debt refers to the accumulation of unresolved issues due to outdated systems, causing risks like non-compliance and loss of scalability.
Healthcare organizations should conduct regular audits, implement security controls, and develop plans for retiring vulnerable legacy systems.
Challenges include a lack of technical knowledge, resistance from decision-makers, and fear of data loss during migration.
Over 40% of healthcare data breaches are attributable to third-party insiders who often possess advanced permissions, increasing the threat landscape.
Migrating can enhance data security, improve interoperability, reduce operational costs, and ultimately ensure compliance with regulations like HIPAA.
