HAC Healthcare Data Visualization & Dashboards 2

Question 1

A healthcare analyst is building a dashboard to track surgical site infection rates across 10 hospitals. Which visualization best supports benchmarking comparisons?

Accepted Answer

Grouped bar chart

Answer

Grouped bar charts allow side-by-side comparison of the same metric across multiple entities, making it easy to benchmark each hospital against others.

Question 2

When visualizing HEDIS quality measure performance, which chart type effectively shows actual performance versus a target threshold simultaneously?

Accepted Answer

Bullet chart

Answer

Bullet charts are designed to display a primary measure against a target and qualitative ranges, making them ideal for HEDIS performance-versus-target comparisons.

Question 3

Which color principle is most important when designing healthcare dashboards for users who may have color vision deficiency?

Accepted Answer

Ensure sufficient luminance contrast and use pattern redundancy

Answer

Ensuring sufficient luminance contrast and adding redundant encoding (such as patterns or labels) makes dashboards accessible to users with color vision deficiencies, not relying on hue alone.

Question 4

A population health manager needs to show the geographic distribution of diabetes prevalence by county. Which visualization is most appropriate?

Accepted Answer

Choropleth map

Answer

Choropleth maps encode quantitative data using color shading across geographic areas, making them ideal for displaying county-level prevalence of conditions like diabetes.

Question 5

Which dashboard interactivity feature allows users to click a region on a map and automatically filter all other charts on the page to that region?

Accepted Answer

Cross-filtering / linked selection

Answer

Cross-filtering (linked selection) synchronizes interactions across multiple visuals so that selecting a region on one chart filters the data displayed in all other charts on the dashboard.
