Question 1

A hospital's case mix index (CMI) increased from 1.45 to 1.62 over one year. What is the most likely implication?

Accepted Answer

The hospital is treating more complex patients, leading to higher expected reimbursement

Answer

A rising CMI indicates the hospital is treating more resource-intensive patients, which typically results in higher MS-DRG reimbursement.

Accepted Answer

Accuracy

Answer

Accuracy is compromised when data does not correctly represent the true value, as with the incorrect systolic reading.
