A Wearable Biosensor Patch for Non-Invasive Monitoring for Patients Undergoing Abdominal or Chest Surgery
Pilot Study on the Clinical Application of a Wearable Biosensor Patch for Non-Invasive Measurement of Biochemical and Blood Gas Analytes
Visão geral do estudo
Status
Descrição detalhada
PRIMARY OBJECTIVE:
I. To evaluate the feasibility of data collection using wearable postoperative biosensor patch.
SECONDARY OBJECTIVES:
I. To evaluate patient acceptability with using the wearable biosensor patch. II. To evaluate the safety of the wearable biosensor patch. III. To assess processes and resources needed to deploy the wearable biosensor patches postoperatively.
EXPLORATORY OBJECTIVES:
I. To explore the consistency of sweat analyte concentrations obtained using the wearable biosensor patch and a standard sweat collector.
II. To explore the accuracy of sweat-derived analyte concentrations relative to peripheral blood measurements (gold standard).
III. To explore the feasibility of intraoperative blood gas monitoring using a transcutaneous biosensor patch measuring oxygen (O₂) and carbon dioxide (CO₂).
IV. To explore the accuracy of O₂ and CO₂ concentrations obtained from the transcutaneous biosensor patch relative to paired intraoperative blood gas measurements (gold standard).
OUTLINE:
Patients have the wearable biosensor patch placed on the upper back or shoulder during surgery and wear it for the duration of the surgery to monitor oxygen and carbon dioxide levels. Starting the day after surgery, patients wear a biosensor patch on their wrist along with a sweat collecting chamber for 2-4 hours, up to twice daily, for up to 3 days post-operatively.
After completion of study intervention, patients may be followed up for up to 1 year.

Experimental: Diagnostic (wearable biosensor patch)
Patients have the wearable biosensor patch placed on the upper back or shoulder during surgery and wear it for the duration of the surgery to monitor oxygen and carbon monoxide levels.
Starting the day after surgery, patients wear a biosensor patch on their wrist along with a sweat collecting chamber for 2-4 hours, up to twice daily, for up to 3 days post-operatively.

Medidas de resultados primários
Medida de resultado |
Descrição da medida |
Prazo |
|---|---|---|
|
Proportion of successful sweat collections (feasibility)
Prazo: Up to 1 year
|
A successful collection will be defined by patch application with data successfully recorded and sent to the database.
Examples of failed collections include, but are not limited to, a patch falling off before data collection can occur or a patch failing to collect and send data to the database.
The number of successful collections will be reported as a proportion of the total number of attempted applications.
All analyses will be descriptive.
Unless otherwise specified, continuous variables will be summarized with mean, standard deviation, median, interquartile range, minimum, and maximum; categorical variables with counts and percentages.
Given the small sample, two-sided 95 percent exact (Clopper-Pearson) confidence intervals will be provided for proportions.
In addition to the overall success rate, the success rates for each type of patch (intraoperative and postoperative) will be described.
All causes of failure (including unknown causes) will be reported.

Descrição da medida |
Prazo |
|---|---|---|
|
Acceptability of the intervention
Prazo: Up to 1 year
|
Assessed using Acceptability of Intervention Measure (AIM) scores and qualitative data analysis of patient exit interviews.
Scores will be summarized descriptively.
Exit interviews will be conducted to explore subjective experience with the biosensor patch.
Topics will include comfort/discomfort while wearing the patch, comfort/discomfort during application and removal, and open-ended feedback.
All analyses will be descriptive.
Unless otherwise specified, continuous variables will be summarized with mean, standard deviation, median, interquartile range, minimum, and maximum; categorical variables with counts and percentages.

|
Incidence of treatment related adverse events related to biosensor use
Prazo: Up to 1 year
|
Safety will be evaluated based on the incidence of treatment-emergent adverse events deemed definitely, probably, or possibly related to the biosensor device.
Adverse events will be graded using the Common Terminology Criteria for Adverse Events version 5.0.
All analyses will be descriptive.
Unless otherwise specified, continuous variables will be summarized with mean, standard deviation, median, interquartile range, minimum, and maximum; categorical variables with counts and percentages.
|
Up to 1 year

|
Processes and resources needed to deploy the wearable biosensor patches postoperatively
Prazo: Up to 1 year
|
Processes and resources needed to deploy the biosensor patches will be assessed through one focus group.
Topics will include: approximate time to setting up the patch for patients and applying them, barriers and facilitators in deploying the patches, and open-ended feedback.
All analyses will be descriptive.
Unless otherwise specified, continuous variables will be summarized with mean, standard deviation, median, interquartile range, minimum, and maximum; categorical variables with counts and percentages.
