CIC Education and Research 4 — Questions and Answers
Question 1: An ICP reviews a study reporting a relative risk (RR) of 0.45 for a hand hygiene intervention. This means:
- The intervention increased infection risk by 45%
- The intervention group had 55% lower infection risk than the control group (Correct answer)
- The intervention had no effect on infection risk
- The infection rate was 0.45 per 1,000 patient days
Correct answer: The intervention group had 55% lower infection risk than the control group
A relative risk of 0.45 indicates that the intervention group experienced 55% less risk (1 - 0.45) compared to the control group.
Question 2: Which type of surveillance is MOST useful for detecting early trends in healthcare-associated infections across a hospital system?
- Targeted surveillance of high-risk units
- Prevalence surveys
- Laboratory-based passive surveillance
- Active prospective surveillance (Correct answer)
Correct answer: Active prospective surveillance
Active prospective surveillance involves systematic, ongoing data collection and is the most sensitive method for early trend detection.
Question 3: When an ICP identifies a knowledge gap through a needs assessment, the FIRST step in addressing it should be:
- Schedule mandatory training immediately
- Set measurable learning objectives (Correct answer)
- Select educational materials
- Evaluate learner outcomes
Correct answer: Set measurable learning objectives
Establishing clear, measurable learning objectives before selecting methods or materials ensures education is goal-directed and evaluable.
Question 4: Which Kirkpatrick level of evaluation measures whether training led to actual changes in workplace behavior?
- Level 1 – Reaction
- Level 2 – Learning
- Level 3 – Behavior (Correct answer)
- Level 4 – Results
Correct answer: Level 3 – Behavior
Kirkpatrick Level 3 evaluates whether learners applied what they learned back in their work environment.
Question 5: A confidence interval (CI) of 95% for an odds ratio of 2.1 (CI: 1.3–3.4) in an infection study indicates:
- The result is not statistically significant
- The true odds ratio likely falls between 1.3 and 3.4 (Correct answer)
- There is a 5% chance the intervention is harmful
- The study has a 95% power to detect an effect
Correct answer: The true odds ratio likely falls between 1.3 and 3.4
A 95% CI that excludes 1.0 indicates statistical significance, and the interval estimates the range within which the true odds ratio likely falls.
Question 6: Which method is considered the gold standard for measuring hand hygiene compliance in clinical settings?
- Product consumption monitoring
- Electronic sensor-based systems
- Direct observation by trained observers (Correct answer)
- Self-reported compliance surveys
Correct answer: Direct observation by trained observers
Direct observation by trained observers is the reference standard recommended by WHO and CDC for measuring hand hygiene compliance.
Question 7: An ICP is developing a competency assessment for proper PPE donning and doffing. Which assessment method is MOST valid?
- Written multiple-choice test
- Case-based scenario review
- Return demonstration with checklist (Correct answer)
- Peer evaluation survey
Correct answer: Return demonstration with checklist
Return demonstration with a standardized checklist directly assesses psychomotor skills and is the most valid method for procedural competency.
