EHR Overlays vs. Full Replacements: Making the Right Choice for Your Practice
TL;DR
- Switching EHRs is fraught with risks, focusing on platform limitations, while overlays address workflow inefficiencies without a complete overhaul.
- EHR overlays like Thyra offer AI-powered workflow enhancements on top of existing systems such as Epic and Athena.
- Implementation of overlays is quick, reversible, and requires minimal disruption compared to full EHR replacements.
When Does It Make Sense to Try an Overlay Instead of Switching EHRs?
Choosing an overlay is ideal when workflow inefficiencies are the primary concern rather than the EHR platform itself. For many healthcare professionals, including endocrinologists, the overwhelming burden of managing inboxes and disconnected follow-ups is a significant challenge. Overlays like Thyra specifically target these workflow gaps by adding functionalities such as inbox triage and automated follow-up processes to your existing EHR. This targeted approach allows practices to enhance efficiency without the need for a full system overhaul, which can be both costly and disruptive.
In addition, overlays are particularly beneficial in practices where the EHR platform itself is sound, but the operational processes are bogged down by inefficiencies. For instance, an endocrinology practice using Epic might face challenges with managing diabetes patient follow-ups due to high CGM data review volume and insulin titration messages. An overlay can automate glucose trend surfacing and follow-up task routing, freeing up clinicians to focus on clinical decisions rather than portal switching and context reconstruction. This not only improves the workflow but also enhances patient outcomes by ensuring timely responses to clinically meaningful glucose patterns.
Why Focus on the Workflow?
Switching EHRs is a significant undertaking often driven by platform limitations like broken billing systems or lack of specialty templates. However, if the frustration stems from processes that occur between visits, like after-hours inbox work or disjointed follow-ups, an overlay is the solution. Thyra connects through SMART on FHIR interfaces, enhancing workflow without replacing the EHR as the source of truth. Additionally, overlays can be tailored to address specific pain points within a practice, ensuring that the most pressing issues are resolved first. This level of customization is often not possible with a complete EHR switch, which tends to be a one-size-fits-all solution.
For example, a primary care practice managing a panel of 1,800 patients with multiple chronic conditions might face challenges coordinating lab follow-ups, medication monitoring, and care gap identification across diabetes, hypertension, and thyroid patients simultaneously. An overlay can automate the follow-up task generation and priority routing for each condition, ensuring that no A1c recheck, TSH follow-up, or medication titration falls through the cracks. This targeted approach not only saves time but also reduces the risk of missed follow-ups that contribute to adverse outcomes.
Can I Try a New EHR Without Switching from My Current System?
Yes, with the overlay model, you can introduce new capabilities without abandoning your current EHR. SMART on FHIR overlays, like Thyra, allow clinics to augment their existing systems with AI-driven workflows. This approach preserves the current EHR for documentation and billing while adding automation features. This means that practices can maintain their existing contracts and avoid the lengthy and often expensive process of migrating data to a new system. Moreover, this approach allows for a gradual transition to new functionalities, ensuring that staff can adapt at their own pace.
Furthermore, overlays provide practices with the opportunity to experiment with new technologies on a smaller scale before committing to a larger investment. For example, an endocrinology group might pilot an overlay to automate prior authorization workflows for GLP-1 medications, assessing its impact on after-hours work and approval turnaround time before deciding to expand its use to inbox triage and follow-up automation. This flexibility allows for iterative improvements and minimizes the risk of adopting new technologies.
What Makes Overlays Flexible?
The flexibility lies in their reversibility. If an overlay proves beneficial by reducing after-hours work or improving task management, you can expand its use. If not, it's easily removable without any impact on the underlying EHR. This flexibility contrasts sharply with full replacements, which are typically irreversible and resource-intensive endeavors. For example, an endocrinology practice might initially implement an overlay to streamline CGM data integration and glucose trend surfacing during inbox review. If successful, they can then expand its use to other areas like automated lab follow-up routing and prior authorization task assembly, gradually enhancing their entire workflow.
Moreover, overlays can be customized to fit the unique needs of a practice, allowing for targeted interventions in problem areas. For instance, an overlay might initially focus on triaging the 50 to 120 daily inbox messages for a busy primary care physician, sorting critical lab results from routine refill confirmations and pre-drafting responses with clinical context attached. As the practice becomes more comfortable with the new workflow, additional features such as automated follow-up task generation from visit notes and care gap identification can be integrated, further enhancing overall efficiency.
What Does Implementation Look Like for an EHR Overlay?
Overlay implementation is straightforward and quick, bypassing the lengthy processes involved in traditional EHR onboarding. Since the existing system remains operational, there's no need for extensive template building or data migration. Overlays integrate seamlessly with minimal disruption. This ease of implementation means that practices can start seeing the benefits of enhanced workflows almost immediately, without waiting months for a full system overhaul to be completed.
This rapid deployment is particularly advantageous for practices facing immediate workflow challenges. For example, an endocrinology practice experiencing high volumes of between-visit patient messages about glucose readings and insulin dosing might implement an overlay to automate context surfacing and response drafting, quickly reducing pajama time and improving response quality. The ability to address such issues swiftly without disrupting ongoing operations is a significant benefit of overlay solutions.
How Quick Is the Deployment Process?
While traditional EHR systems require 10 to 16 weeks for full deployment, overlays like Thyra can be piloted within weeks. This rapid deployment is possible because the overlay leverages existing configurations, focusing on enhancing, not replacing, current functionalities. A typical overlay deployment might start with a pilot involving a single endocrinologist, allowing the practice to assess its impact on inbox processing time and after-hours work before wider implementation.
Moreover, the ability to conduct a pilot program allows practices to gather data and feedback on the overlay's performance, making informed decisions about future expansions. This data-driven approach ensures that any changes made are based on actual needs and outcomes, rather than assumptions, further enhancing the likelihood of success.
How Do You Know If Your Problem Is the EHR or the Workflow?
Determining whether your frustrations are rooted in the EHR platform or workflow inefficiencies is crucial for choosing between an overlay and a full replacement. This decision can significantly impact the efficiency and satisfaction of both healthcare providers and patients.
Key Indicators of Workflow vs. Platform Issues
Signs your problem is the EHR platform:
- Broken billing workflows
- Lack of specialty templates
- Outdated software
These issues often manifest as systemic problems that affect multiple areas of the practice, indicating a need for a complete overhaul.
Signs your problem is the workflow layer:
- Persistent inbox burdens
- Follow-up task disconnects
- Repeated EHR switching with no resolution
These are often isolated issues that can be addressed with targeted solutions like overlays.
If workflow inefficiencies are your primary concern, an overlay is likely the best solution.
Additionally, conducting a thorough assessment of your practice's current operations can help identify the root cause of inefficiencies. Engaging staff in discussions about their daily challenges and observing workflow patterns can reveal whether the issues are due to platform limitations or process inefficiencies. This collaborative approach ensures that any changes made are targeted and effective in addressing the real problem.
What Are the Risks of a Full EHR Replacement?
A full EHR replacement is fraught with potential risks and disruptions. From data migration pitfalls to revenue cycle interruptions, the challenges are numerous and can significantly impact practice operations. Understanding these risks can help practices make informed decisions about whether a switch is truly necessary.
Understanding the Risks
Data Migration: Transferring patient records can lead to data loss and format incompatibility. Medication lists, problem lists, and encounter histories must be mapped between different data models, introducing risk at every step.
Revenue Cycle Disruption: Rebuilding billing workflows can cause financial downturns for up to 90 days post-switch. This disruption can lead to cash flow problems and increased stress for administrative staff.
Staff Retraining: New systems require comprehensive training, diverting time from patient care. It can take months for a practice to fully adapt to a new EHR system, during which productivity and clinical efficiency suffer.
These risks underscore why many practices hesitate to switch EHRs, opting instead for alternatives like overlays that minimize such disruptions.
Moreover, the financial implications of a full EHR replacement can be significant, with costs often exceeding initial estimates due to unforeseen complications. Practices must weigh these potential costs against the benefits of a new system, considering whether the investment will truly address the underlying issues or if a more targeted approach, like an overlay, would be more effective.
What Are the Advantages of an Overlay Approach?
Overlays offer a strategic advantage by distributing risk and enhancing current systems without the upheaval of a full replacement. They provide a way to address specific inefficiencies without the need for a complete overhaul, allowing practices to incrementally improve their operations.
