Clinical Trial Summary

The study team will collect data for this study from participants who are having surgery and recovering postoperatively on 2 pre-designated hospital units. The study team will use vital signs data from a portable device that participants wear on their wrists as well as conventional vital signs data that is collected when a health care provider comes into their room and collect this information. A substudy is also being performed with the distribution of surveys to the nursing staff on the floors who are utilizing the ViSi hemodynamic monitors within our institution.


Description:

This proposed study will provide the necessary preliminary data for a National Institutes of Health Research Grant Project (NIH R01) application that will test the utility of continuous portable hemodynamic monitoring in a large-scale randomized trial. Two separate post surgical hospital units will be randomized to utilize the Sotera ViSi monitoring system or to not utilize the Sotera ViSi monitoring system for a 4 week period of time alternating over the period of 1 year. The study team will assess the effect of unblinded continuous monitoring and the associated alerts on the cumulative duration (min/hour) of each of hypotension, tachycardia, and desaturation. The study team will assess the effect of continuous monitoring and associated alerts on the ordinal clinical intervention outcome which measures the single most extreme/elevated clinical intervention incurred by a patient for any of the 3 outcome variables of interest (hypotension, tachycardia, hypoxia) during the study period with response by staff. The study team will assess the treatment effect on myocardial injury after non-cardiac surgery (MINS) during the study period. A substudy involving the the medical center nursing staffs' impressions of the device as well as their confidence in its utilization in keeping their assigned patient's safe will be assessed.

Outcome

Type Measure Description Time frame Safety issue
Other Incidence of Myocardial Injury After Non-Cardiac Surgery (MINS) Determined by blood troponin levels. Concentrations =0.03 ng/ml will be considered MINS if there is no evidence of a non-ischemic etiology. Ward Admission Ward Admission Through 3rd Postoperative Morning or 48 Continuous Hours (Whichever Comes Earlier)
Other Patient Satisfaction Survey Score ranges from 5-50 with higher score denoting better outcome. Ward discharge on 3rd Postoperative Morning or 48 Continuous Hours (Whichever Comes Earlier)
Other ViSi Monitor Nursing Staff Survey Survey showing the nursing perceptions of Certification for Neurophysiological Intraoperative Monitoring (CNIM) as well as the value of these devices in the care of their patients. Survey will obtain impressions of device from nurses. And descriptive statistics will be obtained regarding nurse's impressions of this technology after its having been implemented. Data will be reported via percentages the responses received. After discharge over a period of 7 days
Primary Duration of Hypotension in Minutes Hypotension defined as MAP <65 mmHg. Ward Admission Through 3rd Postoperative Morning or 48 Continuous Hours (Whichever Comes Earlier)
Primary Duration of Tachycardia in Minutes Tachycardia defined as >110 beats/min. Ward Admission Through 3rd Postoperative Morning or 48 Continuous Hours (Whichever Comes Earlier)
Primary Duration of Hypoxemia (SpO2 < 90%) in Minutes Duration of Hypoxemia defined as SpO2 < 90% in Minutes Ward Admission Through 3rd Postoperative Morning or 48 Continuous Hours (Whichever Comes Earlier)
Secondary Clinical Nursing Intervention Responses Scale Clinical nursing intervention responses over the duration of the trial will be categorized as (1) none, (2) independent nursing intervention, (3) notification of physician team, or (4) activation of the hospital Emergency or Rapid Response System. Scale ranges from 1-4 with 4 denoting a worse outcome. Ward Admission Ward Admission Through 3rd Postoperative Morning or 48 Continuous Hours (Whichever Comes Earlier)
