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.

There is no health care professional more engaged in infection control than a nurse. While the nursing profession offers many levels of responsibility and mastery, every nurse bears the responsibility of controlling and preventing healthcare-acquired infections. In today's post, in honor of National Nurses Week, we will explore the many ways that nurses help keep us safe from healthcare-associated infections (HAIs).
