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?
Answer: 41
Sum = 42 + 38 + 45 + 41 + 39 = 205; mean = 205 ÷ 5 = 41.
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?
Answer: 63%
Omission (35%) plus Dosing (28%) equals 63% of all medication errors.
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?
Answer: 94%
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%.
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?
Answer: The difference is not statistically significant because the confidence intervals overlap
When confidence intervals overlap substantially, the difference between the two estimates is generally not statistically significant.
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?
Answer: Many high-risk, high-cost patients
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.
A monthly report shows total hours of overtime worked: Jan 120, Feb 95, Mar 140, Apr 88, May 110. If the budget allows for 100 overtime hours per month, in how many months was the budget exceeded?
Answer: 3
January (120), March (140), and May (110) all exceed 100 hours — three months exceeded the overtime budget.
An Epic analytics report displays a heat map of patient falls by day of week and shift. The darkest cell is Wednesday/Night shift. What does this mean?
Answer: Wednesday Night shift has the highest fall frequency
In a heat map, the darkest cell represents the highest value — in this case, the highest frequency of patient falls occurring on Wednesday during the Night shift.
