History of Changes
  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. Secondary outcomes will be the fraction of alerts that generate early clinician responses and the consequent increase in MAP.


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

Further study details as provided by Outcomes Research Consortium:

Primary Outcome Measures:
  • reaction time [ Time Frame: 90-day ] [ Designated as safety issue: No ]
    Alert will prompt staff to enact quicker hemodynamic support, thus reduction in mortality


Secondary Outcome Measures:
  • Mean Arterial Pressure (MAP) [ Time Frame: intra-operative ] [ Designated as safety issue: No ]
    Alert will prompt staff to offer quicker hemodynamic support and increase of Mean Arterial Pressure (MAP).


Estimated Enrollment: 9846
Study Start Date: October 2009
Estimated Study Completion Date: November 2013
Estimated Primary Completion Date: November 2012 (Final data collection date for primary outcome measure)
Groups/Cohorts
decision-support alerts
The combination of low MAC, low MAP, and low BIS is thus a "Triple Low", which will set alerts by the Decision-Support System (DSS) .
