Question 1

A sepsis alert fired for 200 patients in a month, and chart review confirmed sepsis in 50 of them. What is the alert's positive predictive value?

Accepted Answer

25%

Answer

Positive predictive value equals true positives divided by all positive alerts, so 50 divided by 200 is 25%.

Question 2

A care management tool not only forecasts which patients are likely to be readmitted but also recommends the intervention most likely to prevent each readmission. Which type of analytics does this represent?

Accepted Answer

Prescriptive

Answer

Prescriptive analytics goes beyond forecasting an outcome by recommending the action to take in response.

Question 3

A research team wants to store raw HL7 feeds, device streams, and clinical notes now and define their structure only when each analysis runs. Which architecture best fits this requirement?

Accepted Answer

Data lake using schema-on-read

Answer

A data lake retains raw data of many types and applies structure at query time through schema-on-read.

Question 4

On a run chart of door-to-balloon times, which pattern is commonly treated as a shift that signals non-random change?

Accepted Answer

Six or more consecutive points on one side of the median

Answer

Under common run chart rules, six or more consecutive points on one side of the median indicate a non-random shift.

Question 5

A population health model uses prior healthcare spending as its proxy for illness burden and consistently under-identifies high-need patients from groups with less access to care. What is the most likely root cause?

Accepted Answer

Label bias from using cost as a proxy for need

Answer

When a target such as cost reflects unequal access rather than true need, the model learns and reproduces that disparity.
