Brief Summary

Rapid response teams (RRTs) have been adopted by hospitals to provide urgent critical care to hospitalized patients who require quick intervention to prevent further deterioration. Early warning scores (EWS) serve as a method to identify patients requiring RRT assessment by analyzing routinely collected data such as vital signs and laboratory results. The Visensia Safety Index (VSI) is an EWS that uses continuous vital sign monitoring and machine learning to identify the likelihood of deterioration and can be integrated with existing hospital data infrastructure. Initial studies of the VSI have both validated the system and found that patients monitored using VSI had a shorter duration of any instability and fewer episodes of serious and persistent instability. The investigators' recent retrospective analysis at The Ottawa Hospital (TOH) identified that implementation of an EWS could have detected earlier deterioration in over half of the patients identified, potentially preventing subsequent ICU admission, severity of illness, and/or mortality. Thus, this study aims to determine the feasibility and potential impact of implementing a portable continuous monitoring system with a VSI trigger at TOH to identify patients at high risk of deterioration.

Outcome Measures

Primary Outcomes (8)

  • Evaluate technical feasibility of collecting greater than 80% of continuous data

    Feasibility of continuous data collection will be evaluated by determining if greater than 80% of continuous data can be collected

    Upon study completion, 10 months after study initiation

  • Evaluate technical feasibility of feeding greater then 80% of continuous data to the predictive tool

    Feasibility of feeding continuous data to the predictive tool will evaluated by determining if greater than 80% of continuous data can be fed to the predictive tool

    Upon study completion, 10 months after study initiation

  • Evaluate technical feasibility of updating the predictive tool on a regular basis greater than 80% of the time

    Feasibility of updating the predictive tool on a regular basis will be evaluated by determining if greater than 80% of the time the predictive tool can be updated on a regular basis

    Upon study completion, 10 months after study initiation

  • Evaluate technical feasibility of reporting greater then 80% of triggers to the RACE team

    Feasibility of reporting triggers to the RACE team will be evaluated by determining if greater than 80% of triggers are reported to the RACE team

    Upon study completion, 10 months after study initiation

  • Evaluate clinical feasibility by assessing MD opinions of the VSI

    Clinical feasibility will be evaluated by assessing MD opinions regarding understanding of the predictive tool, ease of use, perceived strengths and limitations, and perceived enablers and barriers to effective usage through post-encounter surveys and interviews

    Upon study completion, 10 months after study initiation

  • Evaluate clinical feasibility by assessing RN opinions of the VSI

    Clinical feasibility will be evaluated by assessing RN opinions regarding understanding of the predictive tool, ease of use, perceived strengths and limitations, and perceived enablers and barriers to effective usage through post-encounter surveys and interviews

    Upon study completion, 10 months after study initiation

  • Evaluate clinical feasibility by assessing RT opinions of the VSI

    Clinical feasibility will be evaluated by assessing RT opinions regarding understanding of the predictive tool, ease of use, perceived strengths and limitations, and perceived enablers and barriers to effective usage through post-encounter surveys and interviews

    Upon study completion, 10 months after study initiation

  • Evaluate financial feasibility of implementing the VSI system

    Financial feasibility of implementing the VSI system will be evaluated by identifying the costs related to implementation and maintenance of the portable continuous monitoring system through health economic evaluation

    Upon study completion, 10 months after study initiation

Secondary Outcomes (2)

  • Evaluate potential clinical impact of the VSI

    Upon study completion, 10 months after study initiation

  • Evaluate potential financial impact of the VSI

    Upon study completion, 10 months after study initiation

Study Arms (1)

Intervention Arm

EXPERIMENTAL

The Visensia Safety Index (VSI) will be used to alert RACE staff of patient deterioration.

Device: Visensia Safety Index (VSI)

Interventions

Enrolled patients will undergo continuous vital sign monitoring, to be used by the Visensia Safety Index (VSI) to identify early deterioration. If early deterioration is identified, the VSI will produce an alert to notify the RACE team.
