Summary

Rising asthma and COPD cases often go undiagnosed. A population screening identified many undiagnosed or at-risk individuals, suggesting broad screening or targeted questioning is vital for early detection in general practice.

Area of Science:

  • Respiratory Medicine
  • General Practice
  • Public Health

Background:

  • Asthma and COPD prevalence is increasing globally, with many cases remaining undiagnosed in primary care settings.
  • Self-reported symptoms suggestive of asthma/COPD are frequently not formally diagnosed by general practitioners.

Purpose of the Study:

  • To compare the effectiveness of population screening versus a high-risk approach for identifying underdiagnosed asthma and COPD.
  • To determine the prevalence of undiagnosed asthma/COPD in a general practice population.

Main Methods:

  • A case-controlled study involving a record review of 1155 patients.
  • Patients were classified via population screening into asthma/COPD, at-risk, or no asthma/COPD groups.
  • A questionnaire assessed asthma/COPD-related symptoms for a high-risk approach.

Main Results:

  • Population screening identified 85 asthma/COPD diagnoses and 154 at-risk individuals.
  • Nineteen diagnoses were made in cases (previous care) and eight in controls.
  • Only a small fraction of diagnosed cases and controls were known to their general practitioner.

Conclusions:

  • Screening all patients listed in general practice is recommended to reduce undiagnosed asthma and COPD.
  • If universal screening is not feasible, active case finding through targeted symptom questioning is advised for early detection.
