摘要

Chronic obstructive pulmonary disease (COPD) represents a major global health burden, largely attributable to tobacco exposure, including emerging patterns such as early initiation and dual use with electronic cigarettes. Early detection through spirometry in primary care remains suboptimal, potentially limiting timely identification of early disease stages, including Pre-COPD and Preserved Ratio Impaired Spirometry (PRISm). This study aimed to assess whether the implementation of a structured, spirometry-based COPD clinic within primary care networks (Aggregazioni Funzionali Territoriali, AFTs) may be associated with improved diagnostic appropriateness, more consistent therapeutic management, and more efficient use of healthcare resources. We conducted a retrospective observational analysis of routinely collected clinical data from approximately 30,000 patients across three AFTs in the Campania Region (Italy), each including about 10,000 individuals. One AFT was equipped with a dedicated respiratory clinic providing in-house spirometry performed by trained personnel, while the other two followed standard care pathways without structured respiratory services. Key variables included spirometry utilization, diagnostic confirmation of COPD, patterns of care, and selected indicators of healthcare use. In the two standard AFTs, COPD diagnoses were not supported by spirometric confirmation in approximately 65% and 70% of cases, respectively. In contrast, the AFT with a dedicated clinic showed a substantially higher use of spirometry (approximately 80% vs. 30–35%), predominantly performed within the primary care setting. This organizational model was associated with improved alignment between diagnosis and objective testing, and with indicators suggestive of better therapeutic adherence and more appropriate use of secondary care services. The integration of structured, spirometry-enabled respiratory services within primary care networks may contribute to more appropriate COPD diagnosis and management. While the availability of spirometry alone is insufficient, organizational models that incorporate trained personnel, standardized procedures, and coordinated care pathways could represent a potentially effective approach to addressing under- and misdiagnosis in COPD.
