OBJECTIVES: To describe cardiovascular (CV) hospitalizations and estimate related costs in patients who experienced a severe CV event following an exacerbation of Chronic Obstructive Pulmonary Disease (ECOPD).
METHODS: EXACOS-CV program is a set of observational cohort studies. This analysis includes patients with COPD from Canada, Germany, Spain, the Netherlands (NL), identified in secondary databases between 2014-2018. For the present analyses we selected patients who had (hospitalization for acute coronary syndrome, heart failure, stroke or arrhythmias, or death) and an ECOPD within 12 months preceding it. CV-related, respiratory-related and all-cause hospitalizations were described during the 12 months pre-outcome and the 1-3 and 3-12 months post-outcome. The respective across-country cost per capita of hospitalizations were computed in the 12-month prior and 12-month post-outcome.
RESULTS: 43,546 patients were included. In the 12 months pre-outcome, between 23% (Germany) and 44% (NL) of patients already had 1+ CV-related hospitalization. Immediately post-outcome (0-1 month), 32% (Spain), 48% (the NL), 50% (Germany), and 69% (Canada) of patients were no longer in the cohort (attrition primarily due to death). Attrition reached up to 72% at 3-12 months post-outcome (Canada). In the 1-3 months post-outcome, CV-related re-hospitalizations were observed in 3% (Spain) to 21% (Germany) of patients. In the 3-12 months post-outcome, these rates ranged between 10% (Spain) and 32% (NL). The average cost of CV hospitalizations doubled over 12 months post-outcome (€12,551, range: €3582 – €27,394) compared to prior-outcome (€5,010, range: €671 – €10,340) due to both outcome-related hospitalization and re-hospitalizations. Similar trends were seen for all-cause and COPD-related hospitalizations.
CONCLUSIONS: Severe CV events increase HCRU and costs in exacerbating COPD patients namely due to cardiac re-hospitalizations, highlighting the economic burden incurred by increased cardiopulmonary risk in COPD and the urgency for comprehensive clinical management.
