National trends and outcomes of hospitalizations for pulmonary hypertension in Spain (2001–2014)

Abstract Objective To assess changes in incidence, diagnostic procedures, comorbidity profiles, length of hospital stay (LOHS), costs, and in-hospital mortality (IHM) for patients hospitalized with pulmonary hypertension (PH). Methods We included patients hospitalized with PH in Spain from 2001 to 2014. The data were collected from the National Hospital Discharge Database. Results We included 644,436 discharges (43.31% males and 56.09% females) admitted for primary PH (8.34%) or secondary PH (91.66%). The crude incidence rate increased from 58.67 to 148.32 hospitalizations per 100,000 inhabitants between 2001 and 2002 and 2013–2014 ( p p p p Conclusions Despite the increase over time in hospital admissions for PH, associated comorbidity, and costs, LOHS and IHM decreased, suggesting that the management of PH-related hospitalizations improved in Spain during the study period.
