CPHIMS CPHIMS Clinical Informatics Principles 2 — Questions and Answers
Question 1: Which clinical decision support (CDS) intervention type is considered MOST interruptive to clinical workflow?
- Passive reference links
- Hard stop alerts requiring provider action (Correct answer)
- Soft alerts with override capability
- Order sets with pre-selected defaults
Correct answer: Hard stop alerts requiring provider action
Hard stop alerts force the clinician to take a specific action before proceeding, making them the most disruptive CDS intervention.
Question 2: SNOMED CT is primarily used in clinical informatics to represent:
- Billing codes for reimbursement
- Clinical concepts and findings in a structured, computable format (Correct answer)
- Laboratory reference ranges
- Drug interaction rules
Correct answer: Clinical concepts and findings in a structured, computable format
SNOMED CT (Systematized Nomenclature of Medicine Clinical Terms) is a comprehensive clinical terminology used to encode clinical concepts for interoperability and analysis.
Question 3: A hospital notices that nurses are frequently overriding drug allergy alerts. This phenomenon is best described as:
- Alert fatigue (Correct answer)
- Workaround adoption
- System downtime tolerance
- Clinical governance failure
Correct answer: Alert fatigue
Alert fatigue occurs when clinicians become desensitized to frequent alerts, leading to overrides even for potentially significant warnings.
Question 4: In the context of EHR implementation, which strategy BEST reduces unintended consequences related to clinical workflow disruption?
- Deploying the system in all departments simultaneously
- Conducting thorough workflow analysis before and after implementation (Correct answer)
- Limiting end-user training to reduce confusion
- Migrating all legacy data before go-live
Correct answer: Conducting thorough workflow analysis before and after implementation
Analyzing workflows before and after implementation identifies gaps and allows optimization that reduces clinical disruption and patient safety risks.
Question 5: Which HL7 standard is specifically designed to support the exchange of clinical documents such as discharge summaries?
- HL7 v2 ADT messages
- HL7 Clinical Document Architecture (CDA) (Correct answer)
- HL7 FHIR Observation resource
- HL7 v3 RIM
Correct answer: HL7 Clinical Document Architecture (CDA)
HL7 CDA is an XML-based standard for clinical document exchange, commonly used for discharge summaries, referral notes, and care summaries.
Question 6: A physician using CPOE enters a medication order for a patient with a documented penicillin allergy and the system allows the order with only a warning. This is an example of:
- A hard stop
- A passive CDS reminder
- A soft stop (interruptive alert with override) (Correct answer)
- An order set recommendation
Correct answer: A soft stop (interruptive alert with override)
A soft stop alerts the provider to a potential issue but permits the order to proceed if the provider acknowledges and overrides the warning.
Question 7: Which principle guides the design of clinical informatics systems to ensure they support rather than impede clinical judgment?
- Data maximalism
- Human factors engineering (Correct answer)
- Meaningful use compliance
- Structured data capture
Correct answer: Human factors engineering
Human factors engineering applies knowledge of human capabilities and limitations to design systems that reduce errors and cognitive load for clinicians.
