# Performance Measurement in Cardiac Surgery

**Official Title:** Relationship Between Performance Measurement of Intraoperative Mean Arterial Pressure and Mortality in Patients Undergoing Cardiac Surgery

**NCT ID:** [NCT03785132](https://clinicaltrials.gov/study/NCT03785132)

## Key Facts

- **Status:** COMPLETED
- **Study Type:** OBSERVATIONAL
- **Target Enrollment:** 1300
- **Lead Sponsor:** Seoul National University Hospital
- **Conditions:** Blood Pressure
- **Start Date:** 2018-06-01
- **Completion Date:** 2019-11-01
- **CT.gov Last Update:** 2020-03-04

## Brief Summary

This study aimed to evaluate the relationship between the perioperative blood pressure and postoperative mortality after cardiac surgery using performance measurement (PM) of mean arterial pressure (MAP).

## Detailed Description

The authors conducted a retrospective cohort study of adult patients who underwent cardiac surgery requiring cardiopulmonary bypass (CPB). Median performance error (MDPE), median absolute performance error (MDAPE), and wobble of MAP were calculated using preoperative MAP as the reference value, and MBPs before, during and after the bypass as measured values. Univariable and multivariable logistic regression analyses were performed using PM parameters to predict in-hospital mortality. Survival after cardiac surgery was compared using the Cox proportional hazard model. Predictability of PM was assessed using the area under the receiver-operating characteristic curve (AUROC).

## Eligibility

- **Minimum age:** 20 Years
- **Sex:** ALL
- **Healthy Volunteers:** No

```
Inclusion Criteria:

* Patients undergoing cardiac surgery with cardiopulmonary bypass between 2013 and 2016 at Seoul National University Hospital.
