Trial summary

Neonatal jaundice is a common and most often harmless condition. However, when unrecognized it can be fatal or cause serious brain injury. Three quarters of these deaths are estimated to occur in the poorest regions of the world. The treatment of jaundice, phototherapy, is in most cases easy, low-cost and harmless.

About this study

Neonatal jaundice is a common and most often harmless condition. However, when unrecognized it can be fatal or cause serious brain injury. Three quarters of these deaths are estimated to occur in the poorest regions of the world. The treatment of jaundice, phototherapy, is in most cases easy, low-cost and harmless. The crucial point in reducing the burden of disease is therefore to identify then children at risk. This results in the need for low-cost, reliable and easy-to-use diagnostic tools that can identify newborns with jaundice.

Based on previous research on the bio-optics of jaundiced newborn skin, a prototype of a smartphone application was developed and tested in a pilot study and the application refined.

This smartphone application will now be evaluated in a clinical trial set in two hospitals in Norway. The smartphone application gives immediate estimates of bilirubin values in newborns, and these estimates will be compared to the bilirubin levels measured in standard blood samples, as well as the results from ordinary transcutaneous measurement devices.

Read the detailed description

The smartphone jaundice app system works by taking pictures of newborns with a custom-made color calibration card placed on their chest. This makes it possible to measure the skin color precisely regardless of the specific light source that is used to illuminate the newborn. The measured skin color is then compared with items in a database of simulated newborn skin colors. These simulated newborn skin colors have been created using numerical simulations of how light moves through skin, with varying skin parameters including, but not limited to, skin thickness, blood concentration, melanin, and of course bilirubin, the pigment that causes jaundice. By comparing the measured skin color with the simulated skin colors that are most similar to it, the investigators can then estimate the bilirubin concentration in the newborn's skin by e.g. averaging the bilirubin concentrations used to create these simulated skin colors.

In a group of 200 newborns with varying degree of jaundice, correlation between smartphone bilirubin estimates will be compared with total serum bilirubin and standard transcutaneous bilirubinometry.

Study groups in NCT04182555
Study groupRoleWhat they receive
Newborns in St.Olavs Hospital and Haugesund HospitalExperimentalAll newborns will be examined through 4 different methods of determining jaundice.
Receives: Device: Bilirubin estimates from Smartphone Application; Diagnostic Test: Bilirubin concentration measured in standard blood samples; Device: Bilirubin estimates from standard transcutaneous device; Other: Visual assessment of jaundice

What is being measured

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

  1. Smartphone application sensitivity

    Sensitivity of the smartphone application to detect severe jaundice, defined as total serum bilirubin value > 250 umol/l.

    Measured: 5 minutes

Secondary outcomes (4)
  1. Repeatability

    To evaluate the repeatability of multiple measurements with the new smartphone tool

    Measured: 5 min

  2. Correlation between bilirubin estimates by smartphone pictures and by total serum bilirubin

    Estimate of bilirubin levels from smartphone pictures, compared with bilirubin measurements in total serum. Correlation will be expressed by Pearson correlation coefficient, r.

    Measured: 5 minutes

  3. Correlation between bilirubin estimates by smartphone pictures and by standard transcutaneous readings.

    To evaluate the correlation between bilirubin estimates from a smartphone application and bilirubin estimates from a standard transcutaneous device in newborns with varying degree of jaundice. Correlation will be expressed by Pearson correlation coefficient, r.

    Measured: 5 minutes

  4. Correlation between bilirubin estimates by smartphone pictures and visual assessment of jaundice

    • To evaluate the correlation between bilirubin estimates from a smartphone application and bilirubin estimates from visual inspection in newborns with varying degree of jaundice

    Measured: 5 min

Questions about this trial

What is this clinical trial studying?

A study testing Bilirubin estimates from Smartphone Application, Bilirubin concentration measured in standard blood samples and Bilirubin estimates from standard transcutaneous device in people with Jaundice, Neonatal and Hyperbilirubinemia, Neonatal, run by St. Olavs Hospital at 2 sites in Norway.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Sep 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Norway. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Smartphone application sensitivity (time frame: 5 minutes). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Sep 2022.
