RHIT Healthcare Statistics and Analytics 3

Question 1

A hospital has 300 staffed beds and recorded 90,000 inpatient service days in a 365-day year. What is the bed occupancy rate?

Accepted Answer

82.2%

Answer

Bed occupancy rate = (90,000 ÷ (300 × 365)) × 100 = (90,000 ÷ 109,500) × 100 ≈ 82.2%.

Question 2

In healthcare analytics, what does 'sensitivity' of a diagnostic test measure?

Accepted Answer

The proportion of true positives correctly identified by the test

Answer

Sensitivity measures a test's ability to correctly identify those who have the disease (true positive rate).

Question 3

Which type of study design is considered the strongest evidence for establishing a causal relationship?

Accepted Answer

Randomized controlled trial

Answer

Randomized controlled trials (RCTs) minimize bias through random assignment and are the gold standard for establishing causality.

Question 4

A hospital tracks its 30-day readmission rate. Which metric does this primarily reflect?

Accepted Answer

Quality of care and care transitions

Answer

The 30-day readmission rate is used as a quality indicator reflecting the effectiveness of care and transitions between care settings.

Question 5

What is the primary purpose of a confidence interval in healthcare statistics?

Accepted Answer

To express the range within which the true value likely falls

Answer

A confidence interval provides a range of values within which the true population parameter is likely to fall with a specified level of certainty.
