Trial Outcomes & Findings for Optical Detection of Intravenous Infiltration:A Pilot Study (NCT NCT02553421)

NCT ID: NCT02553421

Last Updated: 2017-04-06

Results Overview

The difference in time to detection between the clinician and the ivWatch device is measured from the non-alarming group. This measurement reveals how much earlier the infiltration could have been detected by the ivWatch device compared to the clinician assessments. This metric is measured using the patients in the non-alarming group since an infiltration notification by the ivWatch device could bias the clinician's diagnosis.

Measure
Non-alarming
The ivWatch device will monitor the IV sites but will not issue infiltration notifications. ivWatch Model 400: The ivWatch Model 400 is placed next to the subject's PIV site. All subjects will receive standard care for their IV sites including the normal routine assessments of the IV site by the bedside registered nurses. Patients enrolled into the pilot and non-alarming portion of the study were combined for analysis due to no protocol changes between the study arms.
Alarming
The IV sites will be monitored with the ivWatch Model 400 infiltration notifications enabled. ivWatch Model 400: The ivWatch Model 400 is placed next to the subject's PIV site. All subjects will receive standard care for their IV sites including the normal routine assessments of the IV site by the bedside registered nurses.

The infiltration sensitivity is defined as the percentage of the clinician-confirmed infiltrations that are detected by the ivWatch device before the clinician's diagnosis. This metric is measured and reported separately for non-alarming and alarming groups, since an infiltration notification by the ivWatch device could bias the clinician's diagnosis.

Population: The number of participated in the Alarming group that did not have an infiltration diagnosed by a clinician.

The notification rate is defined as the number of ivWatch device infiltration notifications issued in a certain amount of time, typically reported in units of notifications per day. The notification rate is the number of notifications per day, excluding cases with clinician confirmed infiltrations. This metric is measured using the subjects in the alarming group since the number of notifications could potentially depend on how quickly nurses reset the device.
