Perioperative medicine & outcomes
Association between Preoperative Blood Pressures and Postoperative Adverse Events
Authors' conclusion
Preoperative blood pressures both less than and above a specific threshold were independently associated with a higher number of postoperative adverse events
Study context
- Population
- Adults having elective procedures requiring an inpatient stay, Vanderbilt University Medical Center, November 2017–July 2021
- Participants
- 57,389 cases
- Exposure
- Day-of-surgery preoperative SBP and DBP vs reference values
- Outcome
- Number of postoperative adverse events (myocardial injury, stroke, AKI, mortality)
- Follow-up
- Within 30 days of surgery
Methodological detailsobservational, single-centre, multivariable ordinal logistic regression
- Observational
- Single-centre
- Multivariable ordinal logistic regression
