Association of Final Discharge Blood Pressure with Post-discharge Outcomes Using Electronic Medical Record Data: a Retrospective Study
Abnormal blood pressures are common at hospital discharge; however, few studies have examined the association between discharge systolic blood pressure (SBP) and short-term post-discharge outcomes.1, 2 We examined the association between the last SBP measured during a hospitalization and the odds of 30-day readmission and/or mortality.
The institutional review board at the University of Minnesota approved this study. We included 94,974 emergent hospital admissions from 57,063 patients within a six-hospital network in the Minneapolis/St. Paul area, MN, over 4 years (2012–2016). We excluded non-emergent admissions, patients less than 18 years of age, those who did not consent to their medical record being used for research purposes, or had less than 31 days of follow-up mortality data. We also excluded patients that died during their hospital stay or were discharged to hospice. Our database had complete death records from 2011 onwards for all Minnesotans. In order to...
