Federating worklists across two merging hospital systems requires moving away from siloed, site-specific Picture Archiving and Communication Systems (PACS) and Radiology Information Systems (RIS). Instead, health systems typically implement a "federate before you consolidate" strategy using vendor-neutral workflow orchestration.
The primary architectural and operational steps to unify your reading workflows include the following:

For a hospital-system merger, the goal is usually not to physically merge PACS worklists first. A more scalable approach is to create a federated enterprise radiology workflow layer that presents one prioritized reading queue while allowing images, priors, and reports to remain distributed during the transition. Modern enterprise imaging architectures commonly use standards such as DICOM, HL7, DICOMweb, and FHIR to connect systems across sites.
A typical target architecture looks like this:
Enterprise Worklist Orchestrator
|
------------------------------------------------
| | |
Hospital A Hospital B Hospital C
RIS/PACS RIS/PACS RIS/PACS
| | |
Images Images Images
Reports Reports Reports
Instead of having radiologists log into multiple PACS queues:
This layer becomes the “traffic controller” for imaging operations.
Common capabilities to look for:
The hardest merger problems are often not images—they are identity and workflow.
You will need:
Create a shared MPI (Master Patient Index) strategy:
Map:
Example:
| System A | System B | Enterprise |
|---|---|---|
| CT Abd Pelvis W Contrast | CT A/P IV Contrast | CT Abdomen/Pelvis Contrast |
A common mistake is attempting a full PACS migration before enabling clinical workflow.
A better interim model:
A radiologist clicks a study → the enterprise viewer queries the appropriate archive → retrieves images and priors. DICOM standards such as QIDO-RS for querying and WADO-RS for retrieval support this type of workflow.
Aim for:
One login
One viewer
One reporting ecosystem
During the merger, explicitly define:
Where is the authoritative copy?
Where is the final signed report stored?
Who owns assignment?
Avoid having two systems both believing they control the queue.
A practical sequence:
Your integration team will likely need:
DICOM-based workflows commonly connect RIS/order systems, PACS archives, viewers, and reporting systems through these standards.
Create an enterprise imaging governance group with:

Those answers determine whether you need a lightweight workflow broker or a full enterprise imaging platform.

The most successful enterprise imaging mergers generally do not have radiologists logging into separate PACS worklists for each hospital. Instead, they create a federated worklist that presents studies from multiple facilities as a single prioritized queue while allowing images and reports to remain in their source systems (at least during transition) or migrate gradually to a common archive.
A typical architecture looks like this:
EMRs / RIS (Hospital A) ----\
--> Enterprise workflow engine --> Unified worklist
EMRs / RIS (Hospital B) ----/ |
|
Rules engine / load balancing
|
-----------------------------------------
| | |
PACS Viewer A PACS Viewer B Enterprise Viewer
Key design decisions include:
| Capability | Best practice |
|---|---|
| Worklist | Single enterprise worklist regardless of acquisition site |
| Images | Retrieve from local PACS or enterprise archive transparently |
| Reporting | Shared reporting platform or synchronized report distribution |
| Assignment | Rules-based routing by subspecialty, location, availability, and SLA |
| Licensing | Enterprise identity with SSO rather than separate hospital logins |
| Prior exams | Automatically retrieve priors from any site |
1. Shared PACS/RIS (ideal end state)
Both organizations migrate onto the same PACS, RIS, reporting system, and archive.
Advantages:
Disadvantages:
2. Federated workflow orchestration (common during mergers)
Each hospital initially keeps its own PACS/RIS, but a workflow orchestration layer presents a unified reading queue. When a radiologist opens a case, the orchestrator launches the correct viewer and manages assignment, status, and balancing. This approach minimizes disruption while enabling enterprise-wide reading. Modern standards such as DICOM UPS-RS and IHE Remote Reading Workflow were designed to support this style of cross-enterprise workflow.
Advantages:
3. Enterprise imaging platform
Many health systems instead deploy:
while leaving local acquisition workflows intact.
This often becomes the long-term enterprise architecture.
A federated worklist should route studies based on factors such as:
For example:
Beyond the technology, successful deployments typically standardize:
Useful standards include:
Before selecting a solution, it's helpful to define:
Those answers usually determine whether a workflow orchestrator is sufficient for the near term or whether a full enterprise PACS migration is the better long-term investment.

Federating worklists across two merging hospital systems—especially if they run different PACS, RIS, or vendor ecosystems—requires uncoupling the front-end reading workflow from the back-end storage archives . Rather than forcing an immediate, disruptive "rip-and-replace" of legacy PACS, health systems typically use a phased, interoperable approach.
Here are the core technical and operational strategies to federate your radiology worklists:

To federate radiology worklists across merging hospital systems, your IT and clinical leadership must implement an intelligent Workflow Orchestrator or an Enterprise Imaging Platform . Attempting to merge disparate Picture Archiving and Communication Systems (PACS) or sliding between multiple workstations slows down reading times. A workflow orchestrator acts as a vendor-neutral "brain" that sits on top of your existing infrastructure, aggregating, prioritizing, and dynamically routing studies from any location directly to a radiologist's centralized worklist.
Implementing this setup involves the following core strategic steps:
Rather than trying to merge different electronic health records (EHR) and Radiology Information Systems (RIS) overnight, organizations implement a workflow orchestrator. This software pulls studies from all locations into a single, cohesive view.
Because merging hospital systems often run different vendor platforms (e.g., Merge Healthcare, Intelerad , or Siemens/Epic ), you must reconcile the data so studies can be viewed universally.
Federated worklists allow you to route specific imaging exams to the most qualified reader, regardless of their location.
Radiologists need a unified reporting experience to avoid bouncing between different dictation software and templates.
A federated system requires standardized peer review protocols to maintain care quality across all participating sites.
To help tailor the best technical and operational approach for your merger, could you tell me:

A successful radiology merger typically does not start by merging PACS. Most organizations first federate the reading workflow so radiologists can work across both health systems while the underlying archives, PACS, and RIS are consolidated over time.
A common target architecture looks like this:
Hospital A PACS ─┐
├── Enterprise Worklist Orchestrator ──> Radiologist
Hospital B PACS ─┘ │
├── Rules engine
├── Load balancing
├── Subspecialty routing
├── SLA monitoring
└── Analytics
The worklist orchestrator becomes the "traffic controller" rather than forcing radiologists to log into multiple PACS systems. Modern enterprise imaging platforms increasingly support this federated model, allowing studies to remain in their source systems while presenting a unified reading queue.
1. A unified enterprise worklist
Instead of separate worklists for each hospital, create a single prioritized queue with filters based on:
Radiologists should not need to know which hospital originated the study unless clinically necessary.
Use business rules such as:
This improves turnaround while minimizing "cherry-picking."
Rather than copying every study between PACS systems:
This avoids massive data migrations during the merger and supports phased integration. Enterprise imaging vendors increasingly emphasize federation and streaming for this reason.
Radiologists ideally use:
The more times they switch applications, the more productivity declines.
One of the biggest clinical benefits is automatically presenting prior studies regardless of where they were acquired.
For example:
The viewer should retrieve all relevant priors without manual searching.
When evaluating vendors or designing the architecture, look for support of:
Emerging IHE profiles also address standardized worklist prioritization and remote reading workflows, helping different vendors interoperate more consistently.
Many mergers struggle because each legacy organization keeps its own worklist rules.
Define enterprise-wide policies for:
Without shared governance, a federated worklist can become a source of inconsistent workflows rather than a unifying platform.
This phased approach allows radiologists to function as a single enterprise reading group well before the underlying imaging infrastructure is fully consolidated.
If your organizations use systems such as Epic Radiant, Sectra, GE, Philips, Fuji, Agfa, Visage, Intelerad, or another PACS ecosystem, the optimal federation strategy will depend on those platforms and their interoperability capabilities.

A successful radiology merger is usually less about moving images and more about federating workflow so radiologists experience a single, intelligent worklist regardless of where they are reading.
Most organizations consider three architectural approaches:
| Approach | Advantages | Challenges | Best fit |
|---|---|---|---|
| Single enterprise PACS/RIS | One worklist, unified operations | Large migration effort, downtime risk | Long-term end state |
| Federated worklists (orchestration layer) | Fastest path after a merger, preserves existing systems | Requires integration and governance | Most multi-hospital mergers |
| Separate worklists | Lowest implementation effort | Poor balancing, duplicate coverage, inconsistent turnaround | Temporary only |
For most health systems, a federated worklist is the practical intermediate (and sometimes permanent) solution.
Rather than asking every radiologist to log into multiple PACS, introduce a workflow orchestration layer that:
The images remain in their native archive (or VNA if one exists), while the workflow is centralized.
A federated worklist should support:
Enterprise-wide load balancing
Subspecialty routing
Rules-based prioritization
Ownership controls
Cross-site priors
A standards-based architecture reduces vendor lock-in.
Common standards include:
The technology is only half the solution. Agree on:
Without common governance, a shared worklist can become inconsistent even if the integration is technically successful.
Expect to address:
This phased approach minimizes disruption while allowing radiologists to begin reading studies across the merged enterprise early in the integration.
If your environment includes major platforms such as Epic, Oracle Health/Cerner, Sectra, Visage, Philips, GE HealthCare, Intelerad, Agfa, or a vendor-neutral archive, the integration strategy and available orchestration options can differ significantly. Sharing the current RIS, PACS, VNA (if any), and EHR on each side of the merger would allow for a more tailored architecture recommendation.

Federating worklists across merged hospital systems allows radiologists to read studies from any location, improving efficiency and enabling subspecialty reading across the enterprise. This is typically achieved by shifting workflow control above the individual PACS (Picture Archiving and Communication Systems) to create a unified, centralized, or vendor-neutral environment.

When two hospital systems merge, the goal is usually not to merge PACS on day one. Instead, many organizations deploy a federated enterprise worklist that allows radiologists to read studies across multiple hospitals while each site's PACS and RIS continue operating independently. This approach is commonly used to support mergers, acquisitions, and regional imaging networks.
A typical architecture looks like this:
Hospital A PACS/RIS ─┐
│
Hospital B PACS/RIS ─┼── Enterprise Worklist Orchestrator
│ │
Hospital C PACS/RIS ─┘ │
│
Rules Engine / Load Balancing
│
Universal Diagnostic Viewer
│
Radiologists Anywhere
Rather than creating separate worklists for each hospital, the orchestration layer:
A successful federated worklist generally includes:
| Capability | Why it matters |
|---|---|
| Enterprise worklist | Single queue instead of multiple PACS worklists |
| Intelligent routing | Assigns studies by subspecialty, credentials, location, workload, or contractual obligations |
| Load balancing | Prevents one site from becoming overloaded while another has idle readers |
| Cross-site priors | Displays relevant prior exams regardless of originating hospital |
| Streaming or on-demand image access | Avoids copying every study into one archive immediately |
| Unified reporting workflow | Allows reports to return to the originating RIS/EHR |
Organizations often configure rules such as:
Modern workflow orchestration platforms can also account for radiologist availability, licensing, productivity, and service-level agreements when assigning studies.
Many health systems avoid a "big bang" PACS replacement immediately after a merger.
Federated approach
Full enterprise PACS migration
Many organizations use federation as an interim—or even permanent—solution while gradually standardizing infrastructure.
Your integration team will typically need to address:
Technology alone will not create a successful enterprise reading model. Most health systems also establish:
Several vendors offer enterprise worklist federation and orchestration capabilities, including solutions from Merative (Merge Workflow Orchestrator), AGFA HealthCare (Cross-Enterprise Worklist), and Fujifilm (Synapse Worklist Orchestrator). These platforms are designed to sit above existing PACS environments and provide a unified reading experience across multiple facilities.
If you're in the planning phase of a merger, it's often helpful to think in terms of a phased roadmap:
This phased approach allows radiologists to begin reading from any location relatively quickly while minimizing disruption to clinical operations during the broader integration effort.
