CHC Evidence-Based Practice & Research Methods 5

Question 1

In healthcare construction, 'evidence-based design' (EBD) is best defined as:

Accepted Answer

The deliberate use of credible research to influence the design of the healthcare environment to achieve the best possible outcomes

Answer

EBD intentionally incorporates the best available research evidence to make design decisions that improve measurable patient, staff, and organizational outcomes.

Question 2

Which of the following sampling methods would yield the most representative data when studying patient wayfinding challenges across multiple hospital types?

Accepted Answer

Stratified random sampling across hospital size, type, and geographic region

Answer

Stratified random sampling ensures proportional representation across key subgroups, reducing selection bias and improving generalizability.

Question 3

A CHC professional reviewing a study finds a p-value of 0.03 for a design intervention's effect on HCAI rates. This means:

Accepted Answer

There is a 3% probability of observing the data (or more extreme) if the null hypothesis were true

Answer

A p-value represents the probability of obtaining the observed results by chance alone if there were truly no effect, not the probability the hypothesis is true.

Question 4

When the CHC exam references 'grey literature,' this typically includes:

Accepted Answer

Reports, guidelines, and technical documents not published through commercial academic channels

Answer

Grey literature includes government reports, technical white papers, conference proceedings, and organizational guidelines that fall outside formal peer-reviewed publishing.

Question 5

A healthcare construction team wants to implement a 'Plan-Do-Study-Act' (PDSA) cycle to test a new hand hygiene station placement strategy. In the 'Study' phase, the team should:

Accepted Answer

Analyze data collected during the trial to determine if the change achieved the desired result

Answer

The 'Study' phase of PDSA involves reviewing and analyzing data from the pilot to determine whether the intervention produced the intended improvement.
