Epic Skills Assessment Data and Chart Interpretation 3

Question 1

An Epic dashboard displays a dual-axis chart with bars for patient volume (left axis, hundreds) and a line for average length of stay (right axis, days). In April, the bar reaches 300 and the line is at 4.2. What does each data point represent?

Accepted Answer

300 patients with 4.2 days average stay

Answer

The left axis unit is hundreds, so 300 on that scale = 300 patients, and the right axis measures days, so 4.2 = 4.2 days average length of stay.

Question 2

A control chart for hand hygiene compliance shows a center line at 80%, upper control limit at 94%, and lower control limit at 66%. A data point falls at 97%. What does this indicate?

Accepted Answer

An unusually high result that may warrant investigation

Answer

A point above the upper control limit (94%) indicates a special cause variation — an unusual result that falls outside expected process behavior and should be investigated.

Question 3

A table compares two patient groups: Group A (n=50) with 6 adverse events, and Group B (n=200) with 16 adverse events. Which group has the higher adverse event rate?

Accepted Answer

Group A

Answer

Group A rate = 6/50 = 12%; Group B rate = 16/200 = 8% — Group A has a higher adverse event rate despite fewer absolute events.

Question 4

A stacked bar chart shows patient fall risk categories per unit. The Orthopedic unit bar is tallest and the High Risk segment fills 60% of the bar. The ICU bar is shorter but High Risk fills 80%. Which unit has more high-risk patients?

Accepted Answer

Cannot be determined without knowing total patient counts

Answer

Without knowing the actual total number of patients in each unit, the absolute number of high-risk patients cannot be determined from percentages and bar height alone.

Question 5

Epic's sepsis alert dashboard shows an alert fired at 14:00 but the first antibiotic was given at 15:30. What is the response time lag?

Accepted Answer

90 minutes

Answer

From 14:00 to 15:30 is 1 hour and 30 minutes, which equals 90 minutes.
