What is the case-mix index for a hospital with a sum of relative DRG weights of 15,192 and 10,471 discharges?

To determine the case-mix index (CMI) for a hospital, you divide the sum of relative Diagnosis-Related Group (DRG) weights by the total number of discharges. In this scenario, the sum of relative DRG weights is 15,192, and there are 10,471 discharges.

To calculate the CMI:

1. Divide the sum of relative DRG weights (15,192) by the total discharges (10,471):

CMI = 15,192 / 10,471.

2. Performing this division gives you approximately 1.45.

Therefore, the case-mix index is 1.45, which reflects the complexity and resource needs of the patient population the hospital serves. A higher CMI indicates that the patients being treated are more complex, often requiring more resources and longer hospital stays, making this metric an important measure in understanding a hospital's patient demographics and financial performance.
