CIC Education and Research 5 — Questions and Answers
Question 1: Which data element is ESSENTIAL when calculating a device-associated infection rate using NHSN methodology?
- Number of patients with positive cultures
- Number of device days (Correct answer)
- Total patient admissions
- Number of procedures performed
Correct answer: Number of device days
NHSN device-associated infection rates use device days as the denominator to reflect the actual exposure time to the device.
Question 2: An ICP is planning a study to determine risk factors for CAUTI in ICU patients. Which study design is MOST appropriate?
- Case-control study (Correct answer)
- Randomized controlled trial
- Prevalence survey
- Ecological study
Correct answer: Case-control study
Case-control studies are efficient for identifying risk factors by comparing patients who developed CAUTI (cases) to those who did not (controls).
Question 3: When developing infection prevention education for non-English-speaking healthcare workers, which adaptation is MOST important?
- Translate materials using online translation tools
- Use pictorial job aids and translated materials reviewed by native speakers (Correct answer)
- Provide a bilingual buddy system only
- Deliver education in English with a glossary
Correct answer: Use pictorial job aids and translated materials reviewed by native speakers
Pictorial aids combined with professionally reviewed translated materials address literacy and language barriers while ensuring content accuracy.
Question 4: Which epidemiological term describes the proportion of individuals in a population who have a disease at a specific point in time?
- Incidence rate
- Attack rate
- Point prevalence (Correct answer)
- Cumulative incidence
Correct answer: Point prevalence
Point prevalence measures the proportion of a population affected by a disease at a single defined point in time.
Question 5: When interpreting a run chart showing CLABSI rates, a 'signal' of non-random variation is detected when:
- One data point falls above the mean
- Six or more consecutive data points fall on the same side of the median (Correct answer)
- Two consecutive data points are equal
- The most recent point is the highest on the chart
Correct answer: Six or more consecutive data points fall on the same side of the median
In run chart analysis, six or more consecutive points on the same side of the median is a standard rule indicating non-random, special-cause variation.
Question 6: Which component is MOST critical when writing a measurable learning objective for infection prevention training?
- Specifying the trainer's qualifications
- Including an action verb describing observable performance (Correct answer)
- Listing the training resources to be used
- Identifying the facility's accreditation standards
Correct answer: Including an action verb describing observable performance
Measurable learning objectives must include an observable action verb (e.g., 'demonstrate,' 'identify') to allow objective evaluation of learner performance.
Question 7: An infection preventionist submits a quality improvement project abstract to a professional conference. Before submission, IRB review is typically NOT required when:
- The project involves patient interviews
- The project uses identifiable patient data
- The QI project is not intended to generate generalizable knowledge (Correct answer)
- The project compares two patient groups
Correct answer: The QI project is not intended to generate generalizable knowledge
Quality improvement projects not designed to generate generalizable new knowledge are typically exempt from IRB review, unlike research studies.
