What were the main findings?

Studies that explicitly adopted a systems focus, considering multiple aspects of the healthcare environment, were more likely to demonstrate positive outcomes.. Interventions designed based on a thorough needs assessment or systems analysis phase showed greater effectiveness.. A clear link exists between the design of interventions to enhance safety, quality, efficiency, or well-being and their successful evaluation.

How strong is the evidence?

Evidence strength is rated Strong effect, based on a 2025 journal from BMJ Open Quality.

What are the limitations?

The review's findings are based on published evidence, which may not capture all HFE practices or interventions. The specific operationalization of HFE principles might influence the scope of identified studies.

Short answer

When designing for healthcare, always consider the entire system and how your intervention will interact with its various components, rather than focusing on a single point of failure or improvement.

Field: Human Factors

Method: Scoping Review
Evidence: Strong effect

Human Factors and Ergonomics (HFE) interventions are most effective in healthcare when they adopt a systems perspective, considering multiple interacting elements rather than isolated components. This human factors research insight is drawn from a 2025 study published in BMJ Open Quality. Using Scoping review, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing for healthcare, always consider the entire system and how your intervention will interact with its various components, rather than focusing on a single point of failure or improvement.

Key Findings

01Studies that explicitly adopted a systems focus, considering multiple aspects of the healthcare environment, were more likely to demonstrate positive outcomes.
02Interventions designed based on a thorough needs assessment or systems analysis phase showed greater effectiveness.
03A clear link exists between the design of interventions to enhance safety, quality, efficiency, or well-being and their successful evaluation.

Application

Design takeaway

When designing for healthcare, always consider the entire system and how your intervention will interact with its various components, rather than focusing on a single point of failure or improvement.

How to apply

Before designing a new product or process for healthcare, map out all the relevant interacting systems and stakeholders to understand potential impacts and dependencies.

Project actions

01When defining the scope of your design project, explicitly consider the system in which your design will operate.
02Ensure your research phase includes understanding the needs of all relevant users and stakeholders within that system.

Method & Evidence

AimTo identify and analyze how Human Factors and Ergonomics (HFE) studies in healthcare adhere to core principles of systems focus, design-driven intervention, and outcome-oriented evaluation.

MethodScoping Review

ProcedureA comprehensive review of published literature was conducted to identify studies that met specific criteria related to systems thinking, needs assessment, intervention design for performance/well-being, and evaluation.

ContextHealthcare

Variables

IVAdherence to HFE principles (systems focus, design-driven, outcome-oriented).

DVEffectiveness of HFE interventions (e.g., improvements in safety, quality, efficiency, well-being).

Strengths & Limitations

Strengths

+Comprehensive scoping review methodology allows for broad identification of relevant evidence.
+Focus on core HFE principles provides a clear framework for analysis.

Limitations

It can be challenging to fully capture and analyze all aspects of a complex system within a typical design project scope.

Reliability & validity

The reliability of the scoping review depends on the rigor of the search strategy and the consistency of the criteria application. Validity is enhanced by the systematic approach to evidence synthesis.

Think critically

How might a design that optimizes one part of a healthcare system inadvertently create new problems in another part?

Design Principles

"Adopt a systems-thinking approach in design, recognizing that interventions are part of a larger, interconnected whole."

This approach ensures that interventions are not only designed to address specific issues but also integrated holistically within the complex healthcare environment. By understanding the interdependencies between people, technology, and processes, designers can create solutions that are more robust, sustainable, and impactful.

What This Means for Your Design

To make healthcare better, don't just fix one small problem; look at how everything works together and design changes that fit into the whole picture, making sure to understand what people actually need and then checking if your solution worked.

How to use in your project

1.Reference this study when justifying the importance of a systems approach in your design process, particularly if your project is in a complex environment like healthcare or involves multiple user groups.
