Zorluk: OrtaClassification of Medical Errors and Adverse Events

A 52-year-old man is hospitalized for a pulmonary embolism and is receiving a continuous intravenous unfractionated heparin infusion. During the evening shift change, the day nurse provides a verbal report but omits that the patient's recent activated partial thromboplastin time (aPTT) was subtherapeutic and that the physician recently placed an order to increase the infusion rate. The hospital's electronic medical record lacks a mandatory digital checklist to reconcile pending orders during nursing handoffs. Consequently, the night nurse maintains the prior infusion rate. Six hours later, the patient develops worsening dyspnea, and repeat imaging confirms extension of the pulmonary thrombus. Which of the following patient safety terms best describes the absence of a mandatory digital checklist in this clinical scenario?

  1. A
    Active error
  2. B
    Near miss
  3. C
    Sentinel event
  4. Latent errorCevap
  5. E
    Unpreventable adverse event

Cevap

Latent error
The correct answer is latent error. In the 'Swiss Cheese' model of medical errors, latent errors represent the holes in the system's defenses. These are flaws in protocols, environments, or equipment design (the blunt end of care). In this scenario, the lack of a standardized, mandatory handoff checklist is a latent error that created an environment where the nurse's memory lapse (the active error at the sharp end) could go unnoticed, ultimately leading to patient harm.

Adım Adım Çözüm

1
Analyze the clinical sequence of events
Identified two failures: a nurse forgetting to relay an order, and a hospital system lacking a checklist to prevent such omissions.
Differentiating between human actions and system vulnerabilities is necessary to accurately classify medical errors.
2
Evaluate the specific term requested by the question
The question specifically asks to classify the 'absence of a mandatory digital checklist'.
Focusing on the exact subject of the question prevents incorrectly selecting the term for the nurse's mistake or the patient's outcome.
3
Match the identified flaw with the correct patient safety taxonomy
A system design flaw that sets up frontline workers for failure is defined as a latent error.
Latent errors exist at the 'blunt end' of healthcare and create conditions where active errors (at the 'sharp end') are more likely to occur.

Anahtar Kavram

Latent errors are underlying structural or systemic vulnerabilities (e.g., poor protocols, lack of standardized checklists, faulty equipment design) that facilitate the occurrence of active errors by frontline staff.
