Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are hospitalized patients of any age or race who have recorded blood pressure data.
✕Probably not a fit
Patients who are not hospitalized or have missing blood pressure data will not benefit from this study.

What this trial studies
This observational study aims to explore how inpatient blood pressure levels correlate with adverse events occurring during hospitalization. It includes a diverse population of hospitalized patients of all ages and races, focusing on the primary outcome of all-cause mortality within the hospital setting. By analyzing blood pressure data collected from these patients, the study seeks to identify potential risks associated with varying blood pressure levels during inpatient care.
Why it matters
Potential benefit: If successful, this study could help improve patient monitoring and management strategies in hospitals, potentially reducing adverse outcomes.
How similar studies have gone: While there have been studies examining blood pressure and hospital outcomes, this specific observational approach focusing on all-cause mortality is relatively novel.
