Ethnic disparities in publicly-available pulse oximetry databases

Area of Science:

• Biomedical Engineering
• Clinical Measurement
• Health Equity

Background:

• Pulse oximetry is a critical medical device for monitoring oxygen saturation.
• Previous reports indicate potential inaccuracies in pulse oximetry readings for Black individuals.
• Underrepresentation in clinical data can lead to biased medical device performance.

Purpose of the Study:

• To investigate ethnic representation within pulse oximetry databases.
• To identify potential disparities that could affect device accuracy and clinical utility.
• To inform future research and development for equitable medical technology.

Main Methods:

• Analysis of population demographics across 12 major pulse oximetry databases.
• Quantitative assessment of ethnic representation compared to general population statistics.
• Review of existing literature on pulse oximetry performance across different ethnicities.

Main Results:

• Substantial ethnic disparities were identified in the population numbers within the analyzed databases.
• Specific ethnic groups, including Black individuals, were found to be significantly underrepresented.
• This underrepresentation suggests a potential bias in data used for device validation.

Conclusions:

• Ethnic disparities in pulse oximetry databases pose a risk to accurate patient monitoring.
• Underrepresentation can hinder the development and validation of reliable oximetry devices for all populations.
• Addressing these database disparities is crucial for improving health equity and patient outcomes.
