CHC Evidence-Based Practice & Research Methods 3

Question 1

In healthcare construction research, what does a 'systematic review' differ from a 'narrative review' in?

Accepted Answer

Systematic reviews use predefined protocols and reproducible search strategies

Answer

Systematic reviews follow a rigorous, pre-specified protocol with comprehensive and reproducible literature searches, unlike informal narrative reviews.

Question 2

A CHC project manager wants to evaluate whether single-corridor ICU layouts reduce infection rates compared to double-corridor layouts. Which study design provides the strongest causal evidence?

Accepted Answer

Randomized controlled trial or quasi-experimental design

Answer

Randomized or quasi-experimental designs control for confounding variables and provide the strongest causal inference for comparing interventions.

Question 3

When applying evidence to a healthcare construction project, 'external validity' refers to:

Accepted Answer

Whether the study's findings can be generalized to other settings or populations

Answer

External validity (generalizability) determines whether research findings can be applied to contexts beyond the original study population.

Question 4

Which statistical measure is most useful when combining results from multiple studies in a meta-analysis of healthcare facility outcomes?

Accepted Answer

Pooled effect size with confidence intervals

Answer

Meta-analysis produces a pooled effect size with confidence intervals, quantifying the combined evidence across studies with appropriate uncertainty estimates.

Question 5

A hospital system adopts HCAI prevention guidelines based on research conducted in European hospitals. Before applying these guidelines to a U.S. project, the CHC professional should primarily assess:

Accepted Answer

Differences in patient populations, building codes, and healthcare delivery models

Answer

Contextual differences in patient demographics, regulatory requirements, and care delivery can affect the applicability of foreign research to U.S. healthcare construction.
