Pulmonary Function Tests (PFTs)
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
PFTs involve using a spirometer, a...

Summary
This summary is machine-generated.

Race-based adjustments in spirometry may lead to underdiagnosis and undertreatment for non-White patients. Current practices lack scientific evidence and perpetuate harmful assumptions about lung function across racial groups.

Area of Science:

  • Medical diagnostics
  • Pulmonary medicine
  • Health equity

Background:

  • Race is a social construct, not a biological determinant of lung function.
  • Spirometry and diagnostic tests historically use race adjustment algorithms.
  • Concerns are rising regarding the scientific validity and ethical implications of these adjustments.

Purpose of the Study:

  • To review the historical origins of race adjustment in spirometry.
  • To examine the lack of scientific evidence supporting current race-based spirometry adjustments.
  • To highlight the potential negative consequences of these adjustments on patient care.

Main Methods:

  • Literature review of historical evidence on race adjustment in spirometry.
  • Analysis of existing spirometry reference values and their racial implications.
  • Examination of factors influencing lung function beyond race.

Main Results:

  • Existing spirometry values suggest superior lung function in White patients compared to non-White patients.
  • Race adjustment perpetuates flawed assumptions about biological differences in lung function based on skin color.
  • These adjustments overlook critical factors like environmental exposures, socioeconomic status, and healthcare access.

Conclusions:

  • The practice of race adjustment in spirometry is not scientifically supported and may lead to diagnostic and treatment disparities.
  • Current guidelines may result in underdiagnosis of conditions like asthma and restrictive lung disease in non-White individuals.
  • Reconsideration of automated, race-based adjustments in spirometry is crucial for equitable healthcare.
