Article Overview
This article is for CDI professionals, clinical analytics staff, physician advisors, and hospital quality teams interested in understanding how pandemic-era patient mix can influence case-mix index trends. It discusses a retrospective, data-based approach to separating COVID-19-related cases from other inpatient activity and interpreting changes in CMI and query-related metrics at a high level.
Why This Topic Matters
During the COVID-19 period, usual CDI and quality metrics could shift in ways that were difficult to interpret. The article matters because it offers a way to think about whether observed CMI changes are tied to pandemic-era case mix or to broader CDI and documentation practices.
