Racial Bias and Pulse Oximeters

The pulse oximeter is ubiquitous in hospitals and home care, but the device isn’t always accurate for people with darker skin tones. A special series of the Public Health On Call podcast explores the longstanding issue, why it hasn’t been fixed, and what’s being done about it.

Program Spotlight

Master of Science in Public Health (MSPH)

The Master of Science in Public Health (MSPH) is a professional degree alternative to the Master of Public Health (MPH) degree for students who want more focused skills in a specific field of public health or who lack two years of health-related work experience to begin or advance a career as a public health professional. MSPH programs generally require one academic year of coursework, followed by a field placement. The field placement duration and location vary by department/concentration.
