RESUMO
BACKGROUND AND OBJECTIVES: There are a lot of venous thromboembolism risk assessment models with the aim of predicting the individual risk of venous thromboembolism (VTE), although most have not been externally validated. The objective of our study was to analyse the concordance among the Padua, PRETEMED, IMPROVE and MEDENOX scores. PATIENTS AND METHODS: Observational cohort study with 602 patients admitted to Medical Services of the Hospital Universitario Santa Lucía. Concordance was calculated using the kappa index (KI) between the four risk prediction scales and the VTE occurring within 90 days of hospitalisation. RESULTS: Patients considered were those with a high risk of VTE, 78%, 56%, 69% and 59% according to Padua, PRETEMED, IMPROVE and MEDENOX scores respectively. A KI=0.60 was observed among Padua-IMPROVE scores; KI=0.44 among IMPROVE-PRETEMED, KI=0.43 among PRETEMED-MEDENOX, KI=0.33 among Padua-PRETEMED, KI=0.27 among IMPROVE-MEDENOX and a KI=0.24 among Padua-MEDENOX. During follow-up, nine cases of VTE (1.5%) were observed. CONCLUSIONS: The highest degree of agreement was observed among the Padua and IMPROVE scores. There is no good agreement between any of the predictive risk scales for VTE in medical patients. The Padua score was the best predictor of VTE episodes at 90 days among high risk patients.

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.

BACKGROUND: Factors associated with the detection of raised systolic pulmonary artery pressure (sPAP) levels in patients with a prior episode of pulmonary embolism (PE) are not well known. METHODS: We used the RIETE Registry database to identify factors associated with the finding of sPAP levels ≥50 mm Hg on trans-thoracic echocardiography, in 557 patients with a prior episode of acute, symptomatic PE. RESULTS: Sixty-two patients (11.1%; 95% CI: 8.72-14.1) had sPAP levels ≥50 mm Hg. These patients were more likely women, older, and more likely had chronic lung disease, heart failure, renal insufficiency or leg varicosities than those with PAP levels <50mm Hg. During the index PE event, they more likely had recent immobility, and more likely presented with hypoxemia, increased sPAP levels, atrial fibrillation, or right bundle branch block. On multivariate analysis, women aged ≥70 years (hazard ratio [HR]: 2.0; 95% CI: 1.0-3.7), chronic heart or chronic lung disease (HR: 2.4; 95% CI: 1.3-4.4), atrial fibrillation at PE presentation (HR: 2.8; 95% CI: 1.3-6.1) or varicose veins (HR: 1.8; 95% CI: 1.0-3.3) were all associated with an increased risk to have raised sPAP levels. Chronic heart disease, varicose veins, and atrial fibrillation were independent predictors in women, while chronic heart disease, atrial fibrillation, a right bundle branch block or an S1Q3T3 pattern on the electrocardiogram were independent predictors in men. CONCLUSIONS: Women aged ≥70 years more likely had raised sPAP levels than men after a PE episode. Additional variables influencing this risk seem to differ according to gender.
