California pulmonologist’s research reveals how race-correction formulas may worsen health disparities rather than reduce them.
Dr. Aaron Baugh thought he was doing the right thing. The Black pulmonologist practising in California had long used race-correction formulas in lung function tests, believing these adjustments helped reduce health inequities for his patients.
But when he decided to run the numbers himself, the results left him stunned.
The Moment Everything Changed
What Dr. Baugh discovered challenged everything he’d been taught about pulmonary medicine. Rather than helping Black patients, the race-correction formulas appeared to be causing harm – potentially masking serious respiratory conditions and delaying vital treatment.
His findings sparked a deeper investigation into the widespread use of race correction across medical testing. The practice, embedded in diagnostic tools for decades, adjusts test results based on a patient’s race – ostensibly to account for genetic differences between populations.
Yet Dr. Baugh’s research suggested these corrections might be perpetuating the very health disparities they were designed to address.
A System Under Scrutiny
Race correction in medicine isn’t limited to lung function tests. Similar adjustments exist across numerous diagnostic tools, from kidney function assessments to heart disease risk calculators. The formulas were developed using historical data that often reflected environmental and social factors rather than purely biological differences.
Dr. Baugh’s work adds to growing concerns among medical professionals about whether these corrections help or hinder patient care. Some argue the adjustments can lead to underdiagnosis in Black patients, as others maintain they’re necessary to account for physiological variations.
The debate has particular relevance for respiratory health, where accurate lung function measurements are key for diagnosing conditions like asthma, chronic obstructive pulmonary disease, and occupational lung diseases.

Key Takeaways
- Race-correction formulas in lung function tests may worsen rather than improve health outcomes for Black patients
- A California pulmonologist’s personal investigation revealed potentially harmful effects of these long-standing medical practices
- The findings contribute to broader medical debates about racial adjustments in diagnostic testing
What This Means for Kent Residents
Patients across Kent should feel empowered to discuss diagnostic testing methods with their GPs and specialists, chiefly if they have concerns about how their ethnicity might affect test interpretations. The NHS encourages open dialogue between patients and healthcare providers about treatment decisions. If you have questions about lung function tests or respiratory health, contact NHS 111 for guidance or speak directly with your local practice about referral options to respiratory specialists at Kent’s hospitals.
