Patient Safety and Human Factors in Simulation Flashcards

In the context of healthcare simulation, 'human factors' MOST accurately refers to:

Answer: The study of how environmental, cognitive, and organizational factors affect human performance in complex systems

Human factors (ergonomics) is a scientific discipline examining the interactions between people and the systems they work within — including equipment design, cognitive load, communication, workflow, and environmental conditions — to optimize safety and performance.

A hospital uses in-situ simulation in a newly renovated ICU before opening it to patients. The simulation team discovers that the medication dispensing cabinet is positioned so nurses must turn their backs to the patient during access. This finding is BEST described as a:

Answer: Latent safety threat hidden in the clinical environment

Latent safety threats (LSTs) are hidden hazards embedded in the actual clinical environment — such as equipment placement, workflow design, or communication system gaps — that are not apparent during routine operations but can contribute to adverse events. In-situ simulation is specifically designed to surface these threats before they harm patients.

James Reason's 'Swiss Cheese Model' is MOST useful in simulation education for helping learners understand:

Answer: How multiple aligned system failures, not single errors, typically cause adverse patient events

The Swiss Cheese Model illustrates that accidents occur when the 'holes' (failures) in multiple defensive layers simultaneously align, allowing a hazard to reach the patient. It shifts the focus from individual blame to systems-level analysis of error causation — a foundational patient safety concept.

Which of the following BEST illustrates the concept of 'just culture' as applied to simulation debriefing?

Answer: Distinguishing between unintentional error, at-risk behavior, and reckless conduct to guide proportional, constructive feedback

A just culture framework distinguishes between types of behavior — unintentional human error (support and system fix), at-risk behavior (coaching and awareness), and reckless conduct (accountability) — enabling proportional, fair responses that promote learning without punitive blame.

In-situ simulation is PRIMARILY distinguished from simulation center-based training by its ability to:

Answer: Test and improve clinical workflows, team dynamics, and identify system hazards in the actual care environment

In-situ simulation occurs in the real clinical environment (e.g., the actual ICU, emergency department, or operating room) and is uniquely suited to identifying latent safety threats, testing workflows, and training teams in context — providing ecological validity that simulation centers cannot replicate.

A simulation educator designs a scenario in which a nurse administers the wrong medication due to a look-alike/sound-alike drug stored in the same location. The PRIMARY patient safety learning objective of this scenario is to help learners:

Answer: Recognize how system-level design vulnerabilities contribute to medication errors and practice prevention strategies

This scenario is designed around a systems-level issue — the storage and labeling of look-alike/sound-alike medications — rather than individual knowledge deficit. The learning objective is to help learners identify system vulnerabilities and apply prevention strategies (e.g., independent double-checks, storage protocols).
