human engineering Flashcards
your hospital removed concentrated potassium from general wards because it was being added to IV mixtures and killing people. Removing the concentrated potassium fixes your problem of killing people. What tenet of human factor engineering does this represent?
Forcing function.
…“Skill-based errors tend to be amenable to behaviorshaping constraints that make it hard to perform the wrong action (i.e., forcing functions, such as a microwave that cannot be operated with the door open) and enablers
that make it easy to perform the right action (i.e.,
affordances, such as installing a door handle for pulling and a plate for pushing). “
your hospital goes through a checklist before every major procedure. This is an example of what tenet of human factor engineering?
Standarization….
….”The use of checklists as a
means of ensuring that safety steps are performed, and performed in the correct order, has its roots in human factors engineering principles. Establishing an agreed upon, standardized approach for the basic elements of a procedure allows team members to identify when unintended variances from that approach occur (which may represent errors) and frees the team members to better focus on the unique aspects of the case.”
A patient with an unknown PCN allergy experiences a severe allergic rxn after being given PCN. The hospital then implements a plan to anticipate and adapt to future situations in which a patient’s allergies are unknown. What is this an example of?
Resiliency efforts…….
…….anticipate and adapt to unexpected aberrations in the system.
