The University of Arkansas for Medical Sciences (UAMS) Translational Research Institute (TRI) was established in 2009 with funding from a Clinical and Translational Science Award (CTSA) by the National Center for Advancing Translational Sciences (NCATS) at the National Institutes of Health.

TRI supports translational science research centered on improving the health of all Arkansas. It is also expanding opportunities for UAMS researchers to participate in multisite clinical trials, including collaborative research with other CTSA-funded centers.

Translational Science in Action:

Evaluating Pulse Oximeter Accuracy
in Neonates With Darker Skin Tones

» Translational Research Barrier: Pulse oximeters may provide inaccurate oxygen saturation readings in melanin-rich neonates, potentially delaying treatment and increasing risk of harm. This longstanding issue in clinical device performance has not been adequately addressed in neonatal populations.

» Translational Science Innovation: The project uses objective, quantifiable skin pigmentation data obtained through colorimetry to assess pulse oximeter performance across neonatal populations with varying skin tones. It also links neonatal care and device engineering with the potential to refine or redesign pulse oximeters for better accuracy across skin tones.

» Benefit / Generalizability: Addresses a critical health issue by improving the accuracy of widely used monitoring technology. Could also inform improvements in device calibration for adults and older children and serve as a model for evaluating inaccuracies in other diagnostic tools. The methodology and implementation strategies are generalizable across institutions and patient populations.
