Brief Summary:
Medical errors account for thousands of potentially preventable deaths each year. With the annual increase of surgical cases there is a need for research into the potential utility of a telemedicine-based control center for the operating room to assess risk, diagnose negative patient trajectories, implement evidence-based practices, and improve outcomes.

Condition or disease Intervention/treatment Phase
Surgery Surgery--Complications Perioperative/Postoperative Complications Device: Anesthesia Control Tower monitoring Phase 3

Detailed Description:
This will be a single center, randomized, controlled, phase 3 pragmatic clinical trial. Forty-eight operating rooms will be randomized daily to receive support from the ACT or not. All adults (eighteen years and older) undergoing surgical procedures in these operating rooms will be included and followed until 30-days after their surgery. Clinicians in operating rooms randomized to 'intervention' will receive decision support from clinicians in the ACT. In operating rooms not randomized to receive decision support from the ACT, the current standard of anesthesia care will be delivered. The intention-to-treat principle will be followed for all analyses.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 40000 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: Randomized Parallel assignment
Masking: Single (Participant)
Masking Description: Anesthesia practitioner un-blinded to intervention, subject blinded to intervention, data analyst blinded to intervention, ACT Clinicians un-blinded to intervention
Primary Purpose: Prevention
Official Title: Telemedicine Control Tower for the Operating Room: Navigating Information, Care and Safety - Randomized Pragmatic Trial
Actual Study Start Date : July 1, 2019
Estimated Primary Completion Date : July 2024
Estimated Study Completion Date : July 2024

Arm Intervention/treatment
No Intervention: Standard of care arm
Operating rooms in the standard of care group will be monitored but, the ACT clinicians will not contact the operating room unless it is clinically necessary for patient safety purposes.
Experimental: Anesthesia Control Tower monitoring
Clinicians in the Anesthesiology Control Tower will provide extra support for the anesthesiology team in the operating room using AlertWatch and integrating machine-learning forecasting algorithms for adverse outcomes.
Device: Anesthesia Control Tower monitoring
Real time data will be monitored through the AlertWatch® system as well as the patient's EHR.

Primary Outcome Measures :
  1. Number of Participants with clinically relevant adverse perioperative outcomes. [ Time Frame: 30 days post-op ]
    To assess clinically relevant adverse perioperative outcomes

Secondary Outcome Measures :
  1. Thirty-day postoperative mortality [ Time Frame: 30 days post-op ]
    Definition postoperative mortality provided by Johnson et al. This will include death of any cause occurring in or out of the hospital, within 30 days of the index surgery.

  2. Postoperative delirium [ Time Frame: 30 days post-op ]
    Defined as an acute change in consciousness or cognition. It has a fluctuating course, and is characterized by inattention, disorganized thinking and altered level of consciousness. The institution has trained the nursing staff on our surgical intensive care units to assess all patients for postoperative delirium using the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) instrument.

  3. Postoperative respiratory failure [ Time Frame: 30 days post-op ]
    Defined as mechanical ventilation for greater than 24 hours after surgery, or unplanned postoperative re-intubation and mechanical ventilation within 30 days of surgery.

  4. Postoperative acute kidney injury [ Time Frame: 30 days post-op ]
    Diagnosed when any of the following three criteria are met: (i) an increase in serum creatinine by 50% compared with preoperative within 7 days, (ii) any increase in serum creatinine > 0.3 mg/dL in 48 hours, or (iii) oliguria (urine output <0.5 mL/kg/hr for 6-12 hours).
