2.3 The Systems-Based Approach (Formerly the Environment of Care)
Key Takeaways
- CHD's current exam content outline describes six system components, formerly called the Environment of Care: concepts, people, systems, layout/operations, physical environment, and implementation and evaluation.
- A systems-based approach addresses the components concurrently through an interdisciplinary team so the project can find strategies with the greatest economic, social, and environmental return.
- The outline states that an EBD process alone is not sufficient; changing one component without understanding its relationship to the others can cause unintended consequences.
- Gaps and overlaps among the components should be documented and addressed when implementing transformational change.
- The Joint Commission's Environment of Care standards manage risk in operating facilities, which differs from the planning framework taught for EDAC.
The Systems-Based Approach (Formerly the Environment of Care)
EDAC Core Concept: CHD's current Detailed Content Outline asks candidates to explain why a systems-based approach can enhance and support the EBD process and help the project team find design strategies with the greatest economic, social, and environmental return on investment. The outline lists six components that "define and influence the overall system"—and notes in parentheses that these were formerly called the Environment of Care. Older EDAC study guides and FGI Guidelines functional-program language use the Environment of Care (EOC) terms, so you should recognize both vocabularies.
A systems-based approach treats a healthcare facility as a set of interdependent parts. Multiple components that define the overall system are addressed concurrently by an interdisciplinary team, because the relationships among them—not any single part—drive outcomes.
The Six Components and Their Guiding Questions
The outline pairs each component with a guiding question. Learn the component names and the question each one asks:
| # | Component | Guiding Question in the Outline | Older EOC Wording |
|---|---|---|---|
| 1 | Concepts | Do the design concepts and strategies support the project vision, goals, and objectives? | Delivery of care model (concepts) |
| 2 | People | Does the design define the ideal experiences from the perspectives of all the people who will inhabit the spaces? | Facility and service users (people) |
| 3 | Systems | Do the concepts and ideal experiences consider the direct impact on technical, mechanical, operational, and organizational systems? | Systems design |
| 4 | Layout / operations | Will addressing the components concurrently inform the layout and operation of the spaces to increase desired user outcomes, staff and procedural efficiency, and operational cost reduction? | Layout / operational planning |
| 5 | Physical environment | Which design strategies (interventions) are hypothesized to have a specific outcome, and which metrics will measure those outcomes? | Physical environment |
| 6 | Implementation and evaluation | Where are the opportunities and roadblocks to implementation, and will the implementation strategy achieve the stated goals and objectives? | Implementation |
Notice two shifts from the older list. First, the physical-environment question now explicitly asks for hypothesized outcomes and metrics. Second, the final component is implementation and evaluation, not implementation alone—measurement is built into the system.

Why an EBD Process Alone Is Not Sufficient
The outline makes a pointed claim: an EBD process alone is not sufficient to make improvements; it is more successful when considered with a range of other contributors. Changes to a single component, without understanding its relationship to the others, can have unintended consequences.
Consider a unit that installs decentralized charting alcoves (physical environment) but keeps medications and supplies in one central room (systems), keeps the old assignment pattern (layout/operations), and does no training (implementation). Walking distance and frustration may rise instead of fall. The alcove was not wrong in itself; the other components were left misaligned.
The outline also asks teams to consider all components holistically, including interrelated variables and their influence on each other, when implementing transformational change. There will be gaps and overlaps among the components, and those should be documented and addressed—for example, a gap where no one owns supply replenishment for new alcoves, or an overlap where both IT and nursing are redesigning the same call-light workflow.
How the Team Uses the Components in Practice
| Project Moment | Systems-Based Practice |
|---|---|
| Visioning | Test each goal against all six components before it becomes a project objective |
| Programming | Record how people, systems, and operations will use each space, not only its size |
| Design review | Ask what each physical intervention changes in systems and operations |
| Construction and activation | Plan training, policy changes, and technology go-live alongside the move |
| Post-occupancy | Evaluate outcomes and feed lessons into the next project |
What the Facility Means to Each Stakeholder
EDAC Study Guide 1 adds a useful lens on the "people" component: the same building plays different roles for different groups.
| Stakeholder | The Facility Serves As a... | Design Emphasis |
|---|---|---|
| Patients and families | Healing environment | Safety, privacy, comfort, positive distraction, family presence |
| Staff | Work environment | Efficient layouts, ergonomics, respite, reduced stress and fatigue |
| Providers of healthcare (the organization as a business) | Business environment | Operational efficiency, market position, return on investment |
| Community and organization | Cultural environment | Expression of mission and values; identity in the community |
Study Guide 1 also identifies four areas consistently affected by EBD characteristics: reduction in staff stress and fatigue, improvement in patient safety, reduction in patient stress, and improvement in overall healthcare quality. The link between the environment and organizational culture is covered in Section 2.4.
Don't Confuse the Two Uses of "Environment of Care"
The Joint Commission's Environment of Care (EC) standards require hospitals to manage physical-environment risks through programs such as safety, security, hazardous materials and waste, fire safety, medical equipment, and utility systems. Those standards are about managing risk in an operating facility. The EDAC framework is about planning, designing, implementing, and evaluating a project so its concepts, people, systems, operations, and physical environment work together.
Exam Watch: High-Yield Traps & Pitfalls
[!WARNING] Trap 1: Treating the physical environment as the whole system. It is one of six components. If a well-built space failed, look for a mismatch in concepts, systems, operations, or implementation.
[!WARNING] Trap 2: Forgetting evaluation. The current component is implementation and evaluation—measurement is part of the system, not an afterthought.
[!WARNING] Trap 3: Mixing up facility roles. Patients and families = healing environment; staff = work environment; providers = business environment; community and organization = cultural environment.
In CHD's current exam content outline, which list correctly names the six components of the systems-based approach that were formerly called the Environment of Care?
A hospital adds decentralized nurse alcoves but leaves medications in one central room and provides no workflow training. Walking and frustration increase. Which principle from the exam content outline does this illustrate?
Under the systems-based approach, the physical environment component asks which question?
According to EDAC Study Guide 1, what role does the healthcare facility play for staff?
