A decade ago, most hospital IT teams treated EHR downtime as an infrequent event, something that happened a few times a year during planned maintenance windows or the occasional unexpected server failure. The assumption was that downtime was manageable because it was rare. That assumption no longer reflects the reality of the current operating environment. EHR downtime is becoming more frequent, the causes are more varied, and the duration of significant outage events has increased. The healthcare organizations that built their preparedness programs around the old assumption are finding that those programs do not match the current risk.
Understanding why downtime is increasing, and what specific forces are driving it, is the foundation for building a preparedness program that is calibrated to the actual risk environment rather than the one that existed five years ago.
The Cybersecurity Factor
The single most significant driver of increased EHR downtime frequency in the current environment is cybersecurity. Ransomware attacks on healthcare organizations have increased dramatically in frequency and severity over the past several years. The American Hospital Association has documented ransomware attacks on hospitals resulting in extended EHR outages measured in days or weeks rather than hours, with some large health systems taking two to three weeks to restore full EHR functionality after a major attack.
Healthcare is a particularly attractive target for ransomware actors for several reasons:
- The data healthcare organizations hold, including patient health information and financial records, is highly valuable on criminal markets
- The operational dependency on digital systems, particularly the EHR, creates intense pressure to pay ransoms quickly rather than endure extended downtime
- Many healthcare organizations have underinvested in cybersecurity infrastructure relative to the sensitivity and volume of the data they manage
- The interconnected nature of modern healthcare networks, including EHR integrations with labs, pharmacies, imaging systems, and external providers, creates a large attack surface
The consequence for downtime preparedness is significant. A ransomware-driven outage does not last two hours while IT restores a server. It may last days or weeks while forensic investigation, system remediation, and careful restoration proceed. A downtime preparedness program designed around short outages is fundamentally inadequate for a multi-day ransomware event.
EHR Adoption and Its Downtime Implications
The widespread shift to EHR platforms has changed the downtime risk profile for healthcare organizations in ways that are not always fully appreciated. EHR platforms offer significant advantages in scalability, update management, and infrastructure maintenance. They also introduce a category of downtime risk that on-premise systems do not carry: vendor-side outages.
When an EHR vendor experiences a service disruption, every customer on that platform is affected simultaneously. A single vendor-side incident can take hundreds of hospitals offline at once. These events have occurred with increasing frequency as EHR adoption has grown, and they are entirely outside the control of the affected healthcare organizations. No amount of internal IT investment can prevent a vendor-side outage. The only protection available is a downtime solution that does not depend on the cloud platform to function.
dbtech’s on-premise architecture is specifically designed to address this risk. Because patient data is stored locally and the system does not require internet connectivity or cloud access to function, dbtech remains operational during vendor-side cloud outages as well as local network failures. This architectural choice reflects a clear-eyed view of the current downtime risk environment, where vendor-side cloud incidents are a real and growing category of outage.
The Complexity of Modern EHR Environments
Modern EHR systems are significantly more complex than the systems that were in place a decade ago. They integrate with dozens of external systems, support highly customized workflows, and receive frequent updates and patches that each introduce some level of change risk. The more complex and interconnected the system, the more opportunities exist for something to go wrong.
Specific complexity factors that contribute to increased downtime frequency include:
- Interface failures between the EHR and connected systems, such as the lab information system, pharmacy system, or radiology PACS, which can cause partial or complete EHR outages when upstream or downstream systems experience problems
- EHR update and patch failures, which are a significant source of unplanned downtime as frequent update cycles increase the probability of a failed deployment
- Integration complexity introduced by mergers and acquisitions, as health systems absorb acquired organizations with different EHR platforms and attempt to connect legacy systems to enterprise infrastructure
- Third-party vendor dependencies, where an outage at a technology vendor that the EHR relies on for specific functions can cascade into a broader EHR unavailability event
Staffing and Institutional Knowledge Gaps
A less discussed but significant contributor to downtime frequency impact is the erosion of institutional knowledge that occurred during and after the COVID-19 pandemic. Healthcare experienced unprecedented staff turnover in clinical and IT roles between 2020 and 2024. The experienced IT staff who deeply understood the organization’s EHR infrastructure, integration architecture, and recovery procedures left and were replaced by staff who are still building that knowledge. When systems fail, recovery takes longer when the people responsible for it are newer to the environment.
The same dynamic affects clinical downtime response. Units that lost experienced nursing staff who were deeply familiar with downtime procedures are now staffed by nurses who may have limited downtime training and no practical experience with the backup system. The institutional muscle memory that made downtime events manageable has, in many organizations, been significantly reduced.
What Organizations Should Do Differently Now
Responding to the changed downtime risk environment requires updating preparedness programs in specific ways that match the current threat landscape:
- Extend the planning horizon for downtime duration. A preparedness program designed for two to four hour outages needs to be evaluated and strengthened for multi-day events, particularly in the context of potential ransomware scenarios
- Ensure the downtime solution operates independently of the internet and the primary network. Any solution that requires cloud access or internet connectivity to function is not adequate protection against the most severe current downtime scenarios
- Accelerate training cadence to address the institutional knowledge gap created by staff turnover. Annual training is not sufficient when significant portions of the clinical staff have never experienced a real downtime event
- Treat downtime preparedness as a cybersecurity program element, not just an IT operations function. The CISO and the IT director need to be aligned on downtime preparedness as a shared accountability
- Evaluate whether the current downtime solution vendor has updated its product and integration capabilities to match the current EHR landscape, including cloud-hosted platforms and the most recent versions of major EHR systems
The healthcare organizations that will manage the next generation of downtime events most effectively are the ones that have updated their preparedness programs to reflect what the current risk environment actually looks like, rather than what it looked like when their programs were last built.
