A hospitalized patient's EHR shows conflicting medication allergy entries from two different encounters. Which informatics principle should guide resolution?
Answer: Reconcile using a single source of truth with clinical review
Allergy reconciliation requires clinical review to establish a single authoritative record, preventing both under- and over-documentation of allergies.
Which standard is primarily used to encode clinical diagnoses in US ambulatory care settings for billing and reporting purposes?
Answer: ICD-10-CM
ICD-10-CM (International Classification of Diseases, 10th Revision, Clinical Modification) is the US standard for diagnosis coding in clinical and billing documentation.
A CDS alert fires every time a provider orders acetaminophen, regardless of dose or patient context. This is an example of:
Answer: Alert fatigue from low specificity
Indiscriminate alerts with low specificity cause alert fatigue, leading providers to override even important warnings.
Which clinical informatics approach best supports care coordination for patients with multiple chronic conditions?
Answer: Longitudinal care plans with shared access
Longitudinal care plans with shared access across providers enable coordinated management of complex patients over time.
In the context of clinical decision support, what does 'specificity' refer to?
Answer: The proportion of true negatives correctly identified
Specificity measures how well a CDS tool correctly identifies patients who do NOT have the condition, minimizing false-positive alerts.
A nurse documents a patient fall in a structured incident report system linked to the EHR. What is the PRIMARY informatics benefit of this integration?
Answer: Automated adverse event analysis and safety reporting
EHR-integrated incident reporting enables systematic adverse event tracking, root cause analysis, and quality improvement workflows.
Which workflow change most effectively reduces wrong-patient medication errors in a hospital EHR?
Answer: Positive patient identification before order entry
Positive patient identification (e.g., scanning wristband barcode) before order entry is the leading informatics intervention to prevent wrong-patient errors.
