A new three-step screening strategy significantly improves chronic obstructive pulmonary disease (COPD) detection in primary care. This method efficiently identifies at-risk individuals, reducing the need for extensive spirometry testing.

Area of Science:

  • Pulmonary Medicine
  • Diagnostic Screening
  • Epidemiology

Background:

  • Chronic Obstructive Pulmonary Disease (COPD) is often underdiagnosed in primary care settings.
  • An efficient screening strategy is crucial for improving COPD detection rates.

Purpose of the Study:

  • To evaluate a novel three-step screening method for COPD.
  • The strategy involves a questionnaire, pocket spirometry, and diagnostic spirometry.

Main Methods:

  • Two cross-sectional surveys from Mexico City were analyzed.
  • A COPD risk scale was developed using a questionnaire.
  • Pocket spirometry and ROC curve analysis were employed to assess discriminatory power.

Main Results:

  • The COPD scale demonstrated an Area Under the Curve (AUC) of 0.64-0.77 for COPD detection.
  • Pocket spirometry achieved a higher AUC of 0.85-0.88.
  • The three-step approach significantly reduced the number of individuals requiring spirometry, with a small trade-off in detecting all COPD cases.

    • Conclusions:

    • A three-step screening strategy effectively reduces the need for spirometry testing in primary care.
    • This approach enhances the efficiency of COPD screening and diagnosis.
