Epic Skills Assessment Data and Chart Interpretation 4

Question 1

An Epic report shows the following census data: Monday 42, Tuesday 38, Wednesday 45, Thursday 41, Friday 39. What is the mean daily census for the week?

Accepted Answer

41

Answer

Sum = 42 + 38 + 45 + 41 + 39 = 205; mean = 205 ÷ 5 = 41.

Question 2

A Pareto chart ranks causes of medication errors from most to least frequent: Omission 35%, Dosing 28%, Timing 20%, Documentation 12%, Other 5%. What percentage of errors do the top two causes represent?

Accepted Answer

63%

Answer

Omission (35%) plus Dosing (28%) equals 63% of all medication errors.

Question 3

A flowsheet graph in Epic shows a patient's SpO2 values: 98%, 97%, 96%, 94%, 91%. The alarm threshold is 92%. At which reading should the alarm have triggered?

Accepted Answer

94%

Answer

The alarm threshold is 92%, so the first reading to fall below that threshold is 91%, but the first to trigger should be the reading that breaches 92% — which is 91%; however, the reading of 94% is still above 92%, so the alarm triggers at the 91% reading, which is the first value below 92%.

Question 4

A comparison table shows two hospitals' 30-day readmission rates: Hospital A 14.2% (CI: 12.1%–16.3%) and Hospital B 15.1% (CI: 13.8%–16.4%). What can be concluded about the difference between these rates?

Accepted Answer

The difference is not statistically significant because the confidence intervals overlap

Answer

When confidence intervals overlap substantially, the difference between the two estimates is generally not statistically significant.

Question 5

In Epic's population health dashboard, a bubble chart plots patient risk score (x-axis), cost (y-axis), and bubble size represents number of patients. A large bubble in the upper-right quadrant indicates what?

Accepted Answer

Many high-risk, high-cost patients

Answer

Upper-right = high values on both axes (high risk and high cost); large bubble = many patients — so this represents a large group of high-risk, high-cost patients.
