Spirometry quality in South Africa is largely unsatisfactory, with poor calibration and knowledge of standards. Most practitioners need training in clinical spirometry to improve patient care.

Area of Science:

  • Pulmonology
  • Medical Education

Background:

  • Spirometry use is increasing in South Africa, but formal quality standards are lacking.
  • This study assessed the current standard of spirometry in clinical practice.

Purpose of the Study:

  • To evaluate the quality of spirometry performance and knowledge among practitioners in South Africa.
  • To identify areas for improvement in clinical spirometry practices.

Main Methods:

  • A questionnaire administered via personal interview was used to assess 45 spirometer users.
  • Responses were graded based on correctness, covering calibration, knowledge of standards, patient instructions, and data interpretation.

Main Results:

  • Only 6 spirometers were regularly calibrated; knowledge of standards and calibration was poor to unsatisfactory.

  • Interpretation of results, including acceptability, reproducibility, and bronchodilator response diagnosis, was largely unsatisfactory.
  • Most practitioners lacked knowledge of reference value sources and struggled with diagnosing typical test results.

    • Conclusions:

    • Clinical spirometry standards in South Africa are predominantly unsatisfactory.
    • There is an urgent need for practical, clinical spirometry training at all medical education levels.
