Can the Rome classification of chronic obstructive pulmonary disease exacerbation severity be applied in the hospital setting?

Background: Chronic obstructive pulmonary disease (COPD) exacerbations (ECOPDs) are crucial events in the natural history of the disease. The recent Rome proposal defines exacerbations and their grade of severity using objective parameters derived from published data. Aims: A) To evaluate the applicability of the Rome proposal in current clinical practice in different hospitals settings, B) to compare the resulting degree of severity with the conventional non-objective classification, C) to evaluate the relationship between ECOPD severity and mortality and D) the outputs in different hospital specialist wards. Methods: Observational retrospective study in patients admitted to the University Hospital of Ferrara (Italy) with a primary diagnosis of ECOPD in the year 2021. The items of severity of the Rome proposal at admission were acquired from clinical records. A clinical-based score surrogated the missing VAS data on dyspnoea. Results: Data were collected at admission form 320 patients. The data collected allowed the classification of severity based on the Rome proposal in 88.5 % of eligible cases. 18.5 %, 50.5 % and 31 % of ECOPD admissions were categorised as mild, moderate or severe ECOPDs respectively. In-hospital mortality increased with the ECOPD severity and mortality at 12 months was 27 % and 53.2 % in patients who have had a mild vs severe ECOPD, respectively (p = 0.059). Severe ECOPDs were more frequent and mortality rate was lower in patients admitted to Respiratory as compared to Internal Medicine wards. Conclusion: The Rome classification is ready to use in hospitalised ECOPD. It could allow for a better identification of the hospital setting most appropriate for ECOPD management.
