Continuous Temperature Telemonitoring of Patients With COVID-19 and Other Infectious Diseases in Hospital at Home Using Viture

Completed

• Conditions: Infectious Disease; Tract Infection, Urinary; Bacteremia; Cellulitis; COVID-19; Respiratory Infection
• Interventions: Device: Continuous wearable thermometer placed on patient's armpit to monitor body temperature remotely

• Registration Number: NCT05959928
• Lead Sponsor: Vitio Medical S.L.

Brief Summary

The aim of this cohort study is to validate Viture®, a continuous temperature telemonitoring system, evaluating the level of agreement with a standard commercially available digital axillary thermometer. The study also aims to evaluate the safety and comfort of the system and to evaluate the impact that the introduction of Viture has on the health care practice of a HaH unit. Furthermore, the advantages of Viture compared to the standard method will be evaluated.

Detailed Description

Body temperature is a key vital sign in the follow-up of patients admitted to Hospital at Home (HaH) units with COVID-19 and other infectious diseases. Continuous telemonitoring of temperature can lead to earlier detection of fever and patient deterioration that facilitates early decision making.

In the first day of the study, the patients will be given a study kit of Viture System with the following content:

* Viture Device.

* Digital reference thermometer for control Spot Temperature Measurements (STMs)

* Smartphone with Viture Mobile App installed.

* Device user manual in quick guide format.

* Home data collection notebook (HDCN)

The HaH team will place Viture Device on the patient and train the patient and/or caregiver. They will ask patients to complete control STMs between 3 and 6 times a day on the same arm where the Viture Device is placed and record the measuring data in the HDCN.

In the case that the bracelet is removed, or the patient experience discomfort, they will be asked to fill in the incident in the HDCN. Mild incidents are considered skin alterations such as redness and chafing and severe incidents are considered hematomas and ulcers.

The HaH team on duty will collect all Viture notifications, registering the date, time, and follow-up for each febrile episode. The patient and/or caregiver could be contacted to request a control STM.

A statistical analysis of agreement between the digital reference thermometer (Gold standard) and Viture will be carried out. The non-parametric Wilcoxon signed rank test will be used to evaluate the average agreement between the two methods, and the Bland Altman method will be used to evaluate the agreement between individual measurements. Both analyses will be validated with a 95% confidence interval.

To explore the true potential of Viture, an analysis of the febrile episodes experienced by patients during the clinical study will be performed. Febrile episodes will be characterized by their maximum temperature and duration. To assess the impact of Viture notifications, the data registered on the follow-up of febrile episodes will be analyzed.
