Study summary

The goal of this observational study is to evaluate a commercially available smart sock for heart rate monitoring in hospitalized newborn infants without known heart disease. The study aims to determine whether the smart sock provides heart rate information comparable to that obtained from the standard patient monitor used in routine neonatal care.

The main questions this study aims to answer are:

  • Does the smart sock provide heart rate measurements comparable to those obtained from the standard patient monitor?
  • Does the smart sock provide comparable information on clinically relevant rhythm abnormalities?
  • How do parents and healthcare professionals perceive the usability and safety of the smart sock? Participants will wear the smart sock while undergoing routine monitoring on the neonatal ward. Heart rate and rhythm data from the smart sock will be compared with data from the standard patient monitor. Parents and healthcare professionals will provide feedback on the usability and perceived safety of the device.
Read the detailed description

Commercially available wearable monitoring devices for infants are increasingly used, but evidence on their performance in hospitalized newborns is limited. This study evaluates the accuracy and usability of the Owlet Dream Sock™ in hospitalized newborn infants. Heart rate and rhythm data obtained from the smart sock will be compared with data from the standard patient monitor used in routine neonatal care. In addition, parents and healthcare professionals will evaluate the usability and perceived safety of the device.

Study population

Hospitalized full-term and late preterm newborn infants receiving care in the neonatal intensive care unit and observation unit at Tampere University Hospital, Finland.

Inclusion criteria

  • Hospitalized newborn infant
  • Age \<28 days
  • Gestational age ≥35+0 weeks
  • Birth weight ≥2 kg
  • Parental

Exclusion criteria

Exclusion Criteria:

  • Known congenital heart disease
  • Hospital-acquired infection
  • Skin infection
  • Lack of parental consent
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Agreement between heart rate measurements obtained from the smart sock and the standard patient monitor

    Heart rate data obtained from the smart sock will be compared with simultaneous heart rate data obtained from the standard patient monitor used in routine neonatal care.

    Time frame: From initiation of smart sock monitoring through completion of the 12-16-hour monitoring period

Secondary outcomes

  1. Agreement in detection of rhythm abnormalities between the smart sock and the standard patient monitor

    Rhythm abnormalities and rhythm-related alarms identified by the standard patient monitor will be reviewed and compared with data obtained from the smart sock to assess the ability of the smart sock to detect clinically significant rhythm abnormalities lasting \>3 minutes.

    Time frame: From initiation of smart sock monitoring through completion of the 12-16-hour monitoring period

  2. Parent- and healthcare professional-reported usability of the smart sock

    Usability of the smart sock as assessed by parents and healthcare professionals using a questionnaire.

    Time frame: Immediately after completion of the 12-16-hour smart sock monitoring period

Started Aug 2026 (actual). Primary completion is estimated for Feb 2027, 6 months after the start.

Since we started tracking on Sep 25, 2026, the dates moved once, on Oct 13, 2026: start Sep 2026 → Aug 2026 and primary completion Jan 2027 → Feb 2027.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
