46
Q

What is active error in medical error?

A

Occurs at level of frontline operator (eg, wrong JV pump dose programmed).

-Immediate impact.

47
Q

What is latent error in medical error?

Accident waiting to happen.

A

Occurs in processes indirect from operator but impacts patient care (eg, different types ofIV pumps used within same hospital).

-

48
Q

Name the medical root analysis

A

Root cause analysis

Failure mode and effect analysis

49
Q

Root cause analysis

A

Retrospective approach.
-Applied after failure event to prevent recurrence.

Uses records and participant interviews to identify all the underlying problems (eg, process, people, environment, equipment, materials, management) that led to an error.

50
Q

Failure mode and effects analysis

A

Forward-looking approach.

-Applied before process implementation to prevent failure occurrence.

Uses inductive reasoning to identify all the ways a process might fail and prioritizes them by their probability of occurrence and impact on patients.

51
Q

What is safety culture?

A

Organizational environment in which everyone can freely bring up safety concerns without fear of censure.
-Facilitates error identification

-Event reporting systems collect data on errors for internal and external monitoring.

52
Q

Human factors design

A

Forcing functions (those that prevent undesirable actions [eg, connecting feeding syringe to IV tubing]) are the most effective.

Standardisation ::improves process reliability (eg, clinical pathways, guidelines, checklists).

Simplification::reduces wasteful activities (eg, consolidating electronic medical records
