Technical Dress Rehearsal in Healthcare 101: A Complete Guide for Health System Leaders
What Is a Technical Dress Rehearsal in Healthcare?
A technical dress rehearsal (TDR) is a full-scale simulation of go-live operations conducted before an EHR system, or a major system upgrade, officially launches. Think of it as a practice run that mirrors real clinical and operational workflows as closely as possible, without real patients in the equation.
The goal is to surface problems while there is still time to fix them. By the time a health system reaches go-live, months of configuration, training, and planning are already invested. A TDR is the last major checkpoint to validate that everything built, configured, and trained on will hold up when staff are working under real-time pressure.
TDRs are most commonly used in EHR implementations, but the concept applies to any large-scale health IT deployment: new modules, significant upgrades, migrations, or integrations that affect clinical workflows across multiple departments.
Why Technical Dress Rehearsals Matter
Go-live failures in healthcare are not just operational setbacks. They can delay patient care, create documentation gaps, and put staff in difficult positions when systems do not behave as expected.
A well-executed TDR reduces that risk significantly. It gives organizations a structured opportunity to:
Identify gaps between how the system was configured and how staff actually work
Test interfaces, devices, and integrations under realistic volume conditions
Validate that downtime procedures are understood and executable
Build staff confidence before the first real patient encounter in the new system
Health systems that skip or shorten the TDR process often discover at go-live that their Super Users were not as prepared as expected, that device workflows broke down in fast-paced environments, or that shift handoffs created documentation inconsistencies. These are solvable problems before go-live. They become expensive problems after.
Who Participates in a Technical Dress Rehearsal?
A TDR is not just an IT event. It requires active participation from clinical, operational, and technical stakeholders across the organization.
Core participants typically include:
Leadership Team
The leadership team provides executive oversight, decision-making, escalation management, and overall readiness governance. Their responsibility is to monitor testing progress, remove roadblocks, prioritize issue remediation, manage communications, and ensure go-live readiness.
Testing Team
The testing team performs the hands-on validation of devices, workflows, printers, integrations, and end-user functionality across the healthcare environment. Their responsibility is to execute test scripts, document defects, validate remediation efforts, verify workflow functionality, and confirm that all systems perform as expected in a real-world clinical setting before go-live.
Department Managers
Leadership who need to help assist with scheduling and access to the departments for testing
IT Team
The IT Team is responsible for ensuring all technical components of the EHR environment are operational during go-live. This includes supporting workstations, networks, printers, devices, integrations, user access, and issue remediation to maintain system stability and minimize disruption to clinical operations.
Deployment Team
The Deployment Team is responsible for executing the on-site rollout of the EHR system, validating device readiness, supporting end users, resolving deployment issues, and ensuring that all clinical and operational areas are prepared for go-live. They serve as the frontline team coordinating directly with departments and go-live support resources.
Clinical Informatics and Application Teams
Responsible for documenting workflows, application build, and developing testing scripts.
What Gets Tested During a TDR?
A comprehensive technical dress rehearsal covers more ground than most teams expect. The simulation is designed to stress-test the full patient journey through the system, not just the most common or straightforward use cases.
Key areas tested include:
Patient registration and ADT (Admission, Discharge, Transfer) workflows: Can staff register patients accurately? Do transfers between units carry the right data?
Order management: Are physicians able to enter, modify, and cancel orders without unexpected barriers? Do clinical decision support alerts fire correctly?
Medication administration and pharmacy workflows: Does the medication administration record (MAR) accurately reflect pharmacy orders? Are barcoded medication administration (BCMA) workflows functioning as trained?
Documentation and charting: Can nurses complete flowsheets, assessments, and care plans within a reasonable time? Are documentation requirements realistic given actual shift volume?
Interfaces and integrations: Are lab results flowing from the lab system into the EHR correctly? Are imaging orders and results moving as expected?
Device and hardware functionality: Do barcode scanners, workstations on wheels (WOWs), and bedside devices work as expected across all departments?
Downtime procedures: Do staff understand what to do if the system goes down, and can they execute downtime workflows without confusion?
Shift transitions and handoffs: Are handoff reports generating correctly? Is the data visible and complete when an oncoming nurse logs in?
How Long Does a Technical Dress Rehearsal Take?
The length of a Technical Dress Rehearsal (TDR) depends on several factors, including the size of the organization, scope of the go-live, number of departments involved, and complexity of the environment.
A typical TDR includes planning and preparation, pilot testing, remediation, full TDR testing, and a final revisit. This phased approach gives teams an opportunity to identify issues, make necessary adjustments, and validate that devices, workflows, and integrations are ready for go-live.
Timing is also important. A TDR should take place close enough to go-live that the findings remain relevant, while still leaving enough time to address any issues uncovered during testing. As a general guideline, TDR testing should be completed approximately two weeks before go-live.
Common Technical Dress Rehearsal Findings
Organizations often discover similar categories of issues during a TDR, regardless of how thorough the training and build validation have been. Common findings include:
Device readiness problems
Printers are not mapped correctly; scanners do not read at expected distances, or WOWs do not connect reliably in certain parts of the building.
Downtime procedure unfamiliarity
Staff can identify that a downtime procedure exists, but struggle to execute it under simulated pressure.
None of these findings represents failure. They represent the TDR doing exactly what it is supposed to do: catching fixable problems before they become go-live disruptions.
How to Prepare Your Team for a Technical Dress Rehearsal
Preparation for a TDR starts well before the simulation itself. The organizations that get the most value from their TDR treat it as a milestone event, not a formality.
Steps to prepare:
Define scenarios ahead of time. Work with clinical informatics and department leaders to develop a set of representative patient scenarios that cover common, complex, and edge-case workflows. Scenarios should reflect real patient volume and acuity.
Brief all participants on their role. Staff should know before the TDR what they are being asked to do, what success looks like, and how to escalate issues they find.
Have technical resources on standby. Configuration analysts, interface engineers, and device support staff should be available in real time to address issues as they are identified.
Set up issue-tracking in advance. Use a shared log or ticketing system to capture findings in real time so nothing falls through the cracks during the debrief.
Plan your debrief intentionally. A TDR without a structured debrief loses much of its value. Schedule dedicated time for cross-functional teams to review findings, assign owners, and establish resolution timelines.
The Role of External Support in a Technical Dress Rehearsal
Many health systems bring in external go-live support partners not just for the go-live day itself, but for TDR participation as well. There are a few reasons this matters.
External support staff who participate in the TDR arrive at go-live with context. They have already walked the floors, observed the workflows, identified the departments where staff confidence is lower, and built relationships with the clinical team. That head start is meaningful when the actual go-live is underway and every minute counts.
CSI Companies provides embedded go-live support staffing for Epic implementations, including TDR participation, at-the-elbow support, Super User program development, and command center staffing. Organizations working through a large-scale implementation or upgrade can leverage that expertise from planning through stabilization.
