Recent years have seen heightened interest in developing effective early detection strategies for COPD.


Chronic obstructive pulmonary disease (COPD) is a major health concern globally, leading to significant morbidity and mortality. Notably, a substantial portion of COPD cases, estimated between 70% and 80%, remains undiagnosed. This underdiagnosis results in increased risks of poor health outcomes and diminished quality of life for affected individuals, underscoring the critical need for early detection strategies to mitigate the disease’s impact and lessen the strain on healthcare systems.

Recent years have seen heightened interest in developing effective early detection strategies for COPD, wrote researchers in the International Journal of Chronic Obstructive Pulmonary Disease. The Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2023 guidelines and the updated United States Preventive Services Task Force (USPTF) recommendations endorse case-finding approaches over general population screening. Case-finding focuses on identifying COPD in individuals with respiratory symptoms and risk factors, particularly those with a history of smoking. Despite advancements, the diversity in approaches, criteria, and tools for early COPD detection presents ongoing challenges.

The review highlighted the significance of early COPD detection. Undiagnosed COPD patients face worse health outcomes compared to those diagnosed, with higher rates of exacerbations, pneumonia, respiratory-related deaths, and overall mortality. Early detection can improve management, reduce exacerbations, and enhance the quality of life. Evidence suggests that early intervention, including pharmacological treatment, smoking cessation, and pulmonary rehabilitation, is beneficial even in mild to moderate COPD stages.

A critical element in COPD early detection is the case-finding approach, the research team noted. This strategy is recommended by the 2023 GOLD guidelines due to its targeted nature, focusing on individuals at higher risk, such as those aged 35 or 40 and older with a smoking history. Research shows that case-finding is more effective in these populations compared to younger, less at-risk groups. Additionally, non-smoking-related risk factors, including biomass exposure and occupational hazards, are increasingly recognized as significant contributors to COPD, particularly in low- and middle-income countries (LMICs).

Various tools have been developed for COPD case-finding, addressing barriers to spirometry use. Hand-held spirometers, questionnaires, and prediction models are among the tools validated for identifying undiagnosed COPD. These tools vary in efficiency and applicability, with hand-held spirometers being favored for high-risk individuals and questionnaires useful for broader assessments.

Current progress in COPD case-finding involves refining criteria and incorporating non-smoking-related risk factors. Recent studies emphasize the importance of assessing biomass exposure and suggest integrating smart devices with micro-spirometry for enhanced accuracy and user feedback. Combination tools, merging questionnaires with peak expiratory flow (PEF) devices, are also emerging as cost-effective solutions, particularly for resource-limited settings.

The proposed COPD case-finding flowchart aims to streamline the identification of at-risk patients. It suggests initiating case-finding based on age, smoking history, respiratory symptoms, or biomass exposure. Micro-spirometry is recommended for high-income settings, while combination tools are suited for LMICs. Positive cases should be referred to pulmonologists, and newly diagnosed patients should join integrated care programs. Alternative diagnoses warrant smoking cessation and risk management strategies, highlighting the comprehensive approach needed for effective COPD early detection.
