Which CDSS architecture type embeds decision logic directly within the EHR workflow rather than as a separate application?
Answer: Integrated CDSS
Integrated CDSS embeds decision logic within the EHR workflow, allowing alerts and recommendations to appear natively during clinical documentation.
A CDSS alert fires every time a clinician orders aspirin for any adult patient. This is an example of which alert quality problem?
Answer: Alert fatigue from low specificity
Low specificity causes alerts to fire too broadly, leading to alert fatigue when clinicians repeatedly override non-actionable notifications.
In the context of CDSS, what does the term 'passive CDS' refer to?
Answer: CDS that requires clinician to actively request information
Passive CDS provides information only when the clinician actively seeks it, such as through order sets or infobuttons, without unsolicited interruptions.
Which metric best measures the proportion of CDSS alerts that result in a clinician changing their intended action?
Answer: Alert acceptance rate
Alert acceptance rate measures the percentage of CDSS alerts that lead to a clinician modifying their clinical action, indicating real-world impact.
A hospital wants to implement a CDSS rule to flag patients at risk for acute kidney injury. Which data element is MOST critical for this rule?
Answer: Serum creatinine trend
Serum creatinine trend is the key biomarker for detecting acute kidney injury, as rising creatinine levels indicate declining renal function.
What is the primary purpose of CDS Hooks in modern healthcare interoperability standards?
Answer: To enable EHR systems to call external CDS services at defined workflow points
CDS Hooks is an HL7 standard that allows EHR systems to invoke external CDS web services at specific workflow moments and display results within the EHR.
Which of the following BEST describes a knowledge artifact in clinical decision support?
Answer: A computable representation of clinical knowledge such as a rule or guideline
A knowledge artifact is a structured, computable representation of clinical knowledge—such as an if-then rule, order set, or care plan template—used by a CDSS to generate recommendations.
