title: Trends in hospital admissions for pulmonary embolism in Spain from 2002 to 2011.
abstract: The aim of our study was to analyse changes in the incidence, diagnostic procedures, comorbidity, length of hospital stay, costs and in-hospital mortality of patients hospitalised for pulmonary embolism in Spain over a 10-year period. We included all patients who were hospitalised for pulmonary embolism (ICD-9-CM codes 415.11 and 415.19) as the primary diagnosis between 2002 and 2011. Data were collected from the National Hospital Discharge Database, covering the entire Spanish population. 115 671 patients were admitted. The overall crude incidence increased from 20.44 per 100 000 inhabitants in 2002 to 32.69 in 2011 (p<0.05). In 2002, 13.3% of patients had a Charlson comorbidity index>2, and in 2011 the prevalence increased to 20.8% (p<0.05). Mean length of hospital stay was 12.7 days in 2002 and decreased to 9.99 in 2011 (p<0.05). During the study period, mean cost per patient increased from €3915 to €4372 (p<0.05). In-hospital mortality decreased from 12.9% in 2002 to 8.32% in 2011 (p<0.05). The increase in the use of computed tomographic pulmonary angiography over time was associated with increased incidence and lower mortality. Our results revealed an increase in the incidence of hospitalised pulmonary embolism patients from 2002 to 2011 with concomitant increase in comorbidities and cost. However, length of hospital stay and in-hospital mortality decreased.
