A just-published article, ‘Exploring the causes of COPD misdiagnosis in primary care: A mixed methods study’, by Professor Eddie Patel, Professor Alistair Donaldson, Dr. Harriet Burbridge, Dr. Unice Wright, Dr. Kirsty Craig, and Dr. Euan Miller, in Respirology and Critical Care, outlines a sequential mixed methods research design. The investigation starts with a quantitative part, where 206 patients initially misdiagnosed with chronic obstructive pulmonary disease (COPD) have been studied from the INTEGR COPD study. This phase determined both the prevalence of misdiagnosis and the diagnostic characteristics for these cases. Subsequently, the authors moved to a qualitative stage, consisting of semi-structured interviews of 21 healthcare professionals and 8 patients who experienced wrong diagnoses and were recruited via a purposive sampling method. The overall goal of the research was to identify and interpret the factors that were perceived to contribute to the misdiagnosis of patients presenting with symptoms that would lead to a diagnosis of a respiratory illness, specifically, of chronic obstructive pulmonary disease (COP) in the primary health care setting, and thereby provide a comprehensive picture through the combination of quantitative measures and experiential knowledge.

This article is very reliable for a number of reasons. It has been published in PLOS ONE, a highly regarded, peer-reviewed, open-access scientific journal that has strict publication criteria. The authors are a group of highly experienced researchers and clinicians working with highly-regarded academic and clinical institutions, adding a level of reliability to the findings. Additionally, this study has been registered at the clinical trial identifier registry – NCT03482700, which enhances transparency and helps to adhere to the principles of ethical research. The fact that both quantitative and qualitative data were used adds additional weight to the methodological soundness of the work, and purposive sampling and in-depth thematic analysis employed in the qualitative component contribute extra weight to the validity of the results.

The topic of this article, the misdiagnosis of chronic obstructive lung disease in primary care, is of crucial significance to the health status of patients, as well as the effective use of the health system. Some of the possible consequences of misdiagnosing the disease include poor treatment regimes, misuse of medication and late diagnosis of the disease, and poor quality of life of the patient. The need to misinterpret spirometry tests, diagnostic inertia, and unavailability of diagnostic testing after COVID-19, which perpetuates misdiagnosis is highlighted in the manuscript. This study highlights the significance of specific interventions to address diagnostic misconceptions by isolating the flaws in the system and in education by offering practical information to policymakers, educators, and implementers at the grassroots level.

The implication of the present study is massive for application in the primary and respiratory care environment. The results provide promising perspective of doctors in making specific adjustments to the diagnostic test, especially the interpretation of spirometry, which, despite its importance, is not being used by doctors to diagnose chronic obstructive pulmonary disease. This research highlights the importance of continuous training and capacity building of primary care practitioners, and consequently enhances the diagnostic skills and professional confidence of primary care practitioners. Moreover, it emphasizes the role of multidisciplinary work, and, in particular, the significance of the role of respiratory specialists in regard to complicated or indeterminate cases. It can be assumed that these recommendations will lead to improved accuracy in the diagnosis, the improved use of resources, the reduction of healthcare expenditure, and finally, improved patient care quality, which makes them directly relevant to clinical practice and organizational decision making.
