Randomized Trial of Alerts in Patients Demonstrating a "Triple Low"

This study has been completed.
Sponsor:
Information provided by (Responsible Party):
d sessler, The Cleveland Clinic
ClinicalTrials.gov Identifier:
NCT00998894
First received: October 19, 2009
Last updated: March 20, 2017
Last verified: March 2017
  Purpose
The investigators propose to test the theory that smart alarms for the Triple Low State incorporated into a decision support system built into an electronic anesthesia record will prompt clinicians to intervene earlier in situations that would otherwise provoke little concern, and that the alert system will reduce 90-day mortality. Specifically, the investigators will test the hypothesis that providing Triple Low alerts reduces 90-day mortality.

Condition
Low Bispectral Index Low Mean Arterial Blood Pressure Low End-tidal Anesthetic Concentration

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: A Randomized Effectiveness Trial of Early Hemodynamic Support in Patients Demonstrating a "Triple Low" of Mean-arterial Pressure, End-tidal Anesthetic Concentration, and Bispectral Index

Primary Outcome Measures:
  • 90-day mortality [ Time Frame: 90-days ]

Secondary Outcome Measures:
  • 30-day mortality [ Time Frame: 30-days ]
  • Response to alerts [ Time Frame: Intraoperative ]
    Vasopressor administration within 5 minutes or reduction in volatile anesthetic within 15 minutes of Triple Low onset

  • Hospital-free days within the initial postoperative month [ Time Frame: 30-days ]

Enrollment: 9846
Study Start Date: October 2009
Study Completion Date: December 2016
Primary Completion Date: September 2016 (Final data collection date for primary outcome measure)
Groups/Cohorts
decision-support alerts
In patients experiencing a Triple Low (a combination of low MAC, low MAP, and low BIS), a warning alert will be generated for clinicians.
routine practice
In patients experiencing a Triple Low (a combination of low MAC, low MAP, and low BIS), a warning alert will not be generated for clinicians.
