Education and Research Flashcards

Which data element is ESSENTIAL when calculating a device-associated infection rate using NHSN methodology?

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.

An ICP is planning a study to determine risk factors for CAUTI in ICU patients. Which study design is MOST appropriate?

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).

When developing infection prevention education for non-English-speaking healthcare workers, which adaptation is MOST important?

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.

Which epidemiological term describes the proportion of individuals in a population who have a disease at a specific point in time?

Answer: Point prevalence

Point prevalence measures the proportion of a population affected by a disease at a single defined point in time.

When interpreting a run chart showing CLABSI rates, a 'signal' of non-random variation is detected when:

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.

Which component is MOST critical when writing a measurable learning objective for infection prevention training?

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.

An infection preventionist submits a quality improvement project abstract to a professional conference. Before submission, IRB review is typically NOT required when:

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.
