To assess optimal hypotension definitions for Clostridioides difficile infection (CDI) severity criteria, specifically for fulminant CDI (FCDI).
Key Findings:
The composite endpoint occurred in 8.4% of the Houston cohort and 5.3% of the Midwest cohort, highlighting the clinical relevance of hypotension definitions.
Using either MAP ≤65 mm Hg or SBP ≤90 mm Hg as hypotension criteria was the best-performing model.
Excluding hypotension from the criteria resulted in the worst predictive performance.
Interpretation:
Inclusion of hypotension, defined as SBP ≤90 mm Hg or MAP ≤65 mm Hg, significantly enhances the ability to identify FCDI patients at risk for poor outcomes, underscoring the need for standardized definitions.
Limitations:
The study relied on retrospective data collection, which may introduce bias.
The definition of hypotension was not standardized across all clinical settings prior to this study.
Missing data may impact the robustness of the findings.
Conclusion:
Defining hypotension in FCDI severity criteria is crucial for improving patient outcome predictions.
Large claims analysis finds no significant differences in serious infections, blood clots, or major cardiovascular events across biologics and a Janus kinase inhibitor.
