Newborn Jaundice
Conditions
Brief summary
The goal of this study is to assess the accuracy of BiliCam, a non-invasive technology based on analysis of digital images obtained with an app installed on a commercial smartphone, in estimating total serum bilirubin levels in newborns. BiliCam estimated bilirubin levels will be compared to total serum bilirubin levels in up to 225 newborns.
Detailed description
Jaundice, a yellowing of the skin and eyes caused by a build up of bilirubin in the blood, is a common problem in newborn infants. Measurement of total serum bilirubin (TSB) levels is used for clinical decision making. BiliCam is a non-invasive technology used to estimate TSB levels in newborns. With BiliCam, the user obtains digital images of a small portion of a newborn's skin using the BiliCam app installed on a commercial smartphone in a standardized manner. A color calibration card is placed on the baby's sternum to account for varying light conditions. Data on color levels in the photos are used to estimate a bilirubin level. For the study, paired BiliCam estimated bilirubin (BCB) and TSB levels will be compared on a racially and ethnically diverse sample of newborns. Recruitment will continue until 225 newborns have completed the study.
Interventions
Images will be obtained using the BiliCam app installed on a commercial smartphone and used to calculated a BCB level. The BCB levels will be used for study purposes only and not used for clinical care

| Newborns Newborns will be enrolled in the study in 2 different ways. At Staged Enrollment sites, newborns will be enrolled when they are \< 48 hours old. These newborns will have a study visit when they are 48 - 167 hours old. At the study visit, a BCB will be determined and blood will be drawn for study purposes for a TSB level. At Simultaneous Enrollment sites, newborns will be enrolled and have a study visit at the time of a blood draw (+/- 2 hours) for a TSB level that is being obtained for clinical purposes. Newborns will be 0-191 hours old.

Outcome results
BCB - TSB Correlation
Pearson correlation coefficient between paired BCB- TSB measurements
Time frame: Newborns up to 192 hours old
Population: Participants who completed study visit and had valid paired TSB-BCB results. There were 3 participants in whom blood was obtained for TSB levels, but no valid measurement was available (1 grossly hemolyzed sample, 1 specimen lost, and 1 specimen not obtained within 2 hours of the BCB level). There were 3 participants in whom a BCB level could not be obtained by the study device.
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| Newborns | BCB - TSB Correlation | 0.82 correlation coefficient |
Intercept of Regression Line
The intercept of the regression line of paired BCB TSB values is reported (BCB is the y-axis and TSB is the x-axis).
