- Registration Number
- NCT05108376
- Lead Sponsor
- Ottawa Hospital Research Institute
- 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.

- Primary Outcome Measures
Name Time Method Evaluate technical feasibility of collecting greater than 80% of continuous data Upon study completion, 10 months after study initiation Feasibility of continuous data collection will be evaluated by determining if greater than 80% of continuous data can be collected
Evaluate technical feasibility of reporting greater then 80% of triggers to the RACE team Upon study completion, 10 months after study initiation 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
Evaluate clinical feasibility by assessing RN opinions of the VSI Upon study completion, 10 months after study initiation 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
Evaluate clinical feasibility by assessing RT opinions of the VSI Upon study completion, 10 months after study initiation 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
Evaluate technical feasibility of feeding greater then 80% of continuous data to the predictive tool Upon study completion, 10 months after study initiation 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
Evaluate clinical feasibility by assessing MD opinions of the VSI Upon study completion, 10 months after study initiation 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
Evaluate technical feasibility of updating the predictive tool on a regular basis greater than 80% of the time Upon study completion, 10 months after study initiation 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
Evaluate financial feasibility of implementing the VSI system Upon study completion, 10 months after study initiation 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
- Secondary Outcome Measures
Name Time Method Evaluate potential clinical impact of the VSI Upon study completion, 10 months after study initiation The potential clinical impact of the VSI will be evaluated by comparing the prognostic accuracy of the VSI trigger to clinical gestalt using statistical analysis of performance measures including sensitivity, specificity, positive predictive value, negative predictive value, and area under the curve.
Evaluate potential financial impact of the VSI Upon study completion, 10 months after study initiation The potential financial impact of the VSI will be evaluated by estimating the potential cost savings related to earlier detection of potential deterioration with comparison to historical RACE cohort
