Zorluk: OrtaRoot Cause Analysis and Error Investigation

Following an adverse clinical event involving a patient's intravenous therapy, a root cause analysis identifies several vulnerabilities. The reviewing task force proposes multiple systemic interventions. Match each proposed corrective action to its corresponding position in the hierarchy of safety controls based on established effectiveness and reliability.

  • Forcing function (Strongest reliability)Enteral tubing connectors designed to physically prevent insertion into intravenous lines
  • Standardization and simplification (Intermediate reliability)Integration of a mandatory, pre-populated electronic order set for diabetic ketoacidosis
  • Rules and administrative policies (Weak reliability)Implementation of a dual-nurse independent verification policy for high-alert medications
  • Education and information (Weakest reliability)Distribution of a departmental memorandum detailing the recent adverse event

Cevap

Forcing function pairs with physical enteral connectors; Standardization pairs with electronic order sets; Rules and policies pairs with dual-nurse verification; Education and information pairs with the departmental memorandum.
The hierarchy of safety controls ranks interventions by their ability to sustainably prevent errors. Physical constraints (forcing functions) are the most effective. System changes like standardization are intermediate. Human-dependent interventions (rules, policies, education, and memos) are the least reliable.

Adım Adım Çözüm

1
Identify the action that physically prevents an error from occurring without relying on human behavior.
Matches 'Forcing function' with 'Enteral tubing connectors...'
Physical design changes are the most effective because they bypass human cognitive vulnerabilities.
2
Identify the action that streamlines workflow to reduce cognitive load but does not physically block an action.
Matches 'Standardization' with 'electronic order set...'
Standardized protocols reduce variation and are highly reliable, though slightly less effective than physical forcing functions.
3
Identify the action that dictates workflow but requires active human adherence and vigilance.
Matches 'Rules and administrative policies' with 'dual-nurse verification...'
Administrative mandates rely on human compliance and are subject to fatigue and workarounds, making them weak.
4
Identify the action that solely relies on memory recall of a past event or new knowledge.
Matches 'Education and information' with 'departmental memorandum...'
Information dissemination is the least effective way to prevent future errors because human memory is inherently fallible.
