Introduction: Spirometry is important in the diagnosis and management of chronic obstructive pulmonary disease (COPD), yet it is a common clinical observation that it is underused though the extent is unclear. This survey aims to examine the use of spirometry in the diagnosis and management of COPD patients in districts of, Karachi. Material and Methods: It is a cross-sectional survey involving four clinic settings: hospital-based respiratory specialist clinic, hospital-based mixed medical specialist clinic, general outpatient clinic (primary care), and tuberculosis and chest clinic. Thirty physician-diagnosed COPD patients were randomly selected from each of the four clinic groups. All of them had a forced expiratory volume in 1 second (FEV1) to forced vital capacity (FVC) ratio less than 0.70 and had been followed up at the participating clinic for at least 6 months for COPD treatment. Results: Of the 120 COPD patients, there were 111 males and mean post-bronchodilator FEV1 was 46.2% predicted. Only 22 patients (18.3%) had spirometry done during diagnostic workup, and 64 patients (53.3%) had spirometry done ever. Conclusion: We conclude that spirometry is underused in general but especially by non-respiratory physicians and family physicians in the management of COPD patients. More effort at educating the medical community is urgently needed.
