In our last post, we looked at Diagnosis-Related Groups and how they receive codes based on cost and complexity. These numbers play a key role in the Case-Mix Index, and today we will look at how those MS-DRGs form the basis of the CMI.

The Case-Mix Index (CMI) has been defined in many ways. One definition might read "a relative value assigned to a diagnostic-related group." Another may be "a rough estimate of how sick a hospital's patients are." Yet another could be "an indicator of how much reimbursement is expected by the hospital." All these definitions point to one fact: The CMI is a measure used by a variety of healthcare personnel in a variety of ways. Today we will begin our exploration of this multi-faceted number.

Last  week,  we celebrated Infection Preventionists, the multi-faceted professionals who keep us safe from hospital-acquired infections. This week, we will explore the various pathways individuals can take to become one of these vital healthcare workers, including degrees and certifications.
