Abstract: Background Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality worldwide. However, COPD is still underdiagnosed, undertreated, and not sufficiently prevented. Health administrative databases provide a powerful way of studying COPD in the population. Methods This retrospective study used administrative data, collected during 2011 and 2012, retrieved from 3 Italian local health authorities (LHAs). Results The analysis through administrative databases allowed firstly to identify patients with COPD receiving services by the 3 LHAs: The estimated average is ~3% of the population aged ≥40 years. Furthermore, it was also possible to stratify patients by investigating the health consumption in hospitalization for COPD and use of respiratory drugs. In all 3 LHA patients with moderate COPD were the majority of the population with COPD. Finally, it was possible to distinguish patients who made an appropriate use of SABA (76% of the total), patients who had a potentially inappropriate use (20%), and those with an overuse of SABA (4%). Conclusion The use of SABA consumption patterns can be a reliable proxy variable to detect subgroups who may necessitate therapy revision. Health administrative databases seem beneficial for planning health care interventions, including the COPD field. They are robust information systems subjected to regular data quality controls remaining the prevalent data source, reliable because of the amount of data and the population coverage, especially in countries with a National Health Service System.
