Frequent interruptions and failures in essential systems (medications, orders, supplies, staffing, equipment) significantly fragment nursing tasks, reducing effective patient care time. This human factors research insight is drawn from a 2006 study published in Health Services Research. Using Observational study with mixed methods (direct observation, interviews, surveys) with 11 nurses observed, 6 interviewed, 48 nursing units surveyed, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers must proactively identify and address potential points of failure in operational systems to support efficient and effective human performance, especially in critical service environments.

Key Findings
- 01Nurses experienced an average of 8.4 work system failures per 8-hour shift.
- 02The most frequent failures involved medications, orders, supplies, staffing, and equipment.
- 03Average task time was only 3.1 minutes, with nurses interrupted an average of eight times per shift.
Application
Design takeaway
Designers must proactively identify and address potential points of failure in operational systems to support efficient and effective human performance, especially in critical service environments.
How to apply
When designing workflows or systems for professionals, map out potential failure points and design redundancies or mitigation strategies. Observe users in their natural environment to identify actual interruptions and bottlenecks.
Project actions
- 01When studying a user's workflow, look for what stops them from completing tasks.
- 02Consider how system failures impact user efficiency and stress levels.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Direct observation provides objective data on nurse activities.
- +Mixed methods approach (observation, interviews, surveys) offers a comprehensive view.
Limitations
The observed failures might be specific to the hospitals studied. The impact of interruptions could be subjective and vary between individuals.
Reliability & validity
Reliability was likely enhanced through direct observation and consistent survey administration. Validity is supported by triangulation of data from observation, interviews, and surveys, and by the focus on objective measures of failure frequency and task fragmentation.
Think critically
How might the design of the physical environment or digital interfaces contribute to or mitigate these work system failures?
Design Principles
"Minimize task fragmentation and interruption by designing robust and reliable supporting systems."
Understanding and mitigating work system failures is crucial for optimizing the performance of highly skilled professionals in complex environments. By identifying common points of friction, design interventions can improve workflow, reduce cognitive load, and ultimately enhance the quality and safety of services provided.
What This Means for Your Design
Nurses are constantly stopped from doing their jobs by things like missing supplies or wrong medication orders. This makes their work very broken up and means they have less time for patients.
How to use in your project
- 1.Use this research to justify the need for improving a system that causes frequent interruptions or failures for users.
- 2.Cite this study when discussing the impact of external factors on user productivity in your design project.

Paragraph starter
Research indicates that work system failures, such as issues with medications, orders, supplies, staffing, and equipment, are a significant source of interruption for healthcare professionals, averaging 8.4 failures per shift. These disruptions fragment tasks, reducing effective work time and potentially impacting performance and safety. Therefore, designing systems that are robust to interruption and implementing processes to reduce failure recurrence is critical for optimizing professional effectiveness.
