About this study

Official title: Improving the Measurement of Neonatal High Blood Pressure Using the Boppli Device

This study evaluates a new, non-invasive device (Boppli™) that continuously measures blood pressure in newborn infants. The study compares Boppli measurements to standard blood pressure cuff measurements to determine how well the device works and whether it improves identification of high blood pressure in infants in the neonatal intensive care unit (NICU). The study also includes follow-up through 1 year of age to understand longer-term outcomes.

Read the detailed description

High blood pressure in newborn infants (neonatal hypertension) is increasingly recognized but remains difficult to diagnose. There is no single standard definition, and current blood pressure measurements rely on intermittent cuff-based methods. These cuff measurements can be affected by infant movement, agitation, and measurement technique, which may lead to inaccurate classification of blood pressure.

The Boppli™ device is a non-invasive monitoring system that uses a soft band placed on the infant to continuously measure blood pressure using pulse wave signals. Unlike standard cuffs, the device does not inflate and may reduce measurement-related variability.

This is a prospective observational study conducted in infants admitted to the NICU who are less than 5 kg and are at risk for high blood pressure or have clinical concern for elevated blood pressure. The study does not change clinical care, and Boppli measurements will not be used for medical decision-making.

The study has three parts:

Part 1: Feasibility and Comparison of Measurements Infants will wear the Boppli device for up to 72 hours while standard blood pressure cuff measurements are collected as part of routine care. Measurements from the two methods will be compared to evaluate how closely they agree. The study will also assess how easy the device is to use and how well it is tolerated by infants, families, and clinical staff.

Part 2: Effect of Cuff Measurements on Blood Pressure Infants will continue Boppli monitoring for 72 hours. Blood pressure cuff measurements will be obtained during the first 24 hours, stopped during the second 24 hours, and resumed during the third 24 hours. This design allows the study team to evaluate whether cuff measurements themselves affect blood pressure readings. The ability of the Boppli device to identify high blood pressure will be compared to cuff-based definitions.

Part 3: Follow-up After Hospital Discharge (Exploratory) Infants with concern for high blood pressure during hospitalization will be followed through 1 year of age. Blood pressure, growth, and clinical outcomes will be collected from routine clinic visits or study visits. This part of the study will evaluate whether early blood pressure findings persist and whether infants require treatment.

The main outcome of the study is whether the Boppli device can be used successfully in the NICU and how well its measurements agree with standard cuff measurements. Additional outcomes include how accurately the device identifies high blood pressure and whether cuff measurements influence blood pressure readings. Longer-term outcomes will describe blood pressure patterns and clinical care during infancy.

This study is considered minimal risk. The device is non-invasive, and participation will not affect the medical care infants receive.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • BoppliDevice

    The Boppli™ device is a non-invasive, wearable blood pressure monitoring system designed for use in neonates and infants. The device consists of a soft sensor band placed on the infant that continuously measures pulse waveforms to estimate blood pressure without the use of cuff inflation.

    In this study, the device will be applied for up to 72 hours to collect continuous blood pressure data. Measurements obtained from the device will be recorded for research purposes only and will not be used to guide clinical care or medical decision-making.

NICU InfantsExperimentalInfants at-risk for chronic neonatal hypertension (cnHTN) have blood pressures assessed with the Boppli device. These assessments will be compared to those of standard inflatable cuffs.
Receives: Device: Boppli

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Feasibility and agreement of Boppli to cuff based measurements

    Feasibility will be assessed by the proportion of successful blood pressure measurements obtained using the Boppli™ device during the monitoring period and user-reported ease of use. Agreement will be assessed by comparing measurements obtained from the Boppli™ device to those obtained from standard cuff-based measurements using paired measurements.

    Measured: 72 hours

Secondary outcomes (3)
  1. Diagnostic accuracy of Boppli™ device for identification of elevated blood pressure

    Sensitivity, specificity, positive predictive value, and negative predictive value of Boppli™-derived blood pressure measurements for identifying elevated blood pressure (≥95th percentile for post-menstrual age) compared to standard cuff-based definitions.

    Measured: 72 hours

  2. Agreement in classification of elevated blood pressure between Boppli™ and cuff measurements

    Proportion of infants classified as having elevated blood pressure (≥95th percentile for post-menstrual age) by Boppli™ monitoring compared to classification by standard cuff-based measurements.

    Measured: 72 hours

  3. User-reported feasibility and acceptability of the Boppli™ device

    Assessment of caregiver and clinical staff experience using a voluntary survey evaluating ease of use, device performance, and infant tolerance

    Measured: 72-144 hours
