Question 1

Which CDSS architecture type embeds decision logic directly within the EHR workflow rather than as a separate application?

Accepted Answer

Integrated CDSS

Answer

Integrated CDSS embeds decision logic within the EHR workflow, allowing alerts and recommendations to appear natively during clinical documentation.

Question 2

A CDSS alert fires every time a clinician orders aspirin for any adult patient. This is an example of which alert quality problem?

Accepted Answer

Alert fatigue from low specificity

Answer

Low specificity causes alerts to fire too broadly, leading to alert fatigue when clinicians repeatedly override non-actionable notifications.

Question 3

In the context of CDSS, what does the term 'passive CDS' refer to?

Accepted Answer

CDS that requires clinician to actively request information

Answer

Passive CDS provides information only when the clinician actively seeks it, such as through order sets or infobuttons, without unsolicited interruptions.

Question 4

Which metric best measures the proportion of CDSS alerts that result in a clinician changing their intended action?

Accepted Answer

Alert acceptance rate

Answer

Alert acceptance rate measures the percentage of CDSS alerts that lead to a clinician modifying their clinical action, indicating real-world impact.

Question 5

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?

Accepted Answer

Serum creatinine trend

Answer

Serum creatinine trend is the key biomarker for detecting acute kidney injury, as rising creatinine levels indicate declining renal function.
