Which type of clinical decision support alert fires when a clinician attempts to order a medication that the patient has documented allergy to?
Answer: Drug-allergy alert
A drug-allergy alert is triggered at order entry when the ordered medication conflicts with a documented patient allergy.
In the context of CDS, what does 'infobutton' refer to?
Answer: A context-sensitive link that retrieves relevant reference information at the point of care
An infobutton provides context-sensitive access to reference knowledge resources based on the clinical context (patient, condition, medication) at the point of care.
A hospital wants to reduce inappropriate antibiotic use. Which CDS intervention is best suited for stewardship at the time of prescribing?
Answer: Order set with preferred agents and required justification fields
An antibiotic order set with built-in preferred-agent guidance and mandatory indication fields provides stewardship at the prescribing moment.
Which metric best evaluates whether a CDS alert is being acted upon appropriately?
Answer: Alert override rate
The alert override rate reveals how often clinicians bypass alerts; a high rate may indicate alert fatigue or poorly calibrated rules.
What is the primary purpose of a drug-drug interaction (DDI) checker in a clinical decision support system?
Answer: To warn prescribers when two ordered medications have a known adverse interaction
A DDI checker cross-references the patient's medication list and warns the prescriber of known pharmacological interactions between co-prescribed drugs.
Which standard enables EHR systems to share CDS rules using a common, interoperable format?
Answer: HL7 FHIR CDS Hooks
CDS Hooks is an HL7 FHIR-based standard that allows external CDS services to integrate with EHR workflows at defined trigger points.
A CDS rule recommends beta-blockers for all patients with a diagnosis of heart failure. A patient with severe asthma receives this recommendation. This illustrates which CDS limitation?
Answer: Failure to account for contraindications in recommendation logic
The rule failed to incorporate contraindication logic (asthma is a contraindication to non-selective beta-blockers), producing a potentially harmful recommendation.
