Deep-vein thrombosis in Europe — Burden of illness in relationship to healthcare resource utilization and return to work

Objectives: Deep-vein thrombosis (DVT) forms a major healthcare burden in Europe, but exact estimates concerning the economic burden on society are lacking. This study reports results from the PREFER in VTE study concerning resource utilization and absence from work in DVT patients. Methods: The PREFER in VTE registry was a prospective, observational, multicenter study carried out in Europe (France, Italy, Spain, the UK, and DACH [Germany, Switzerland and Austria]), designed to provide data concerning treatment patterns, resource utilization, mortality and quality of life. Patients with a first-time and/or recurrent DVT, were recruited and followed for 12 months. Data about resource utilization concerns resource utilization related to DVT. Specifically, treatment pattern, re-hospitalization rate, length of hospital stay, ambulatory/office visit, and proportion of patients returning to work, were analyzed and presented. Subgroup analysis by country and active cancer were also conducted. The length of hospital stay was analyzed as a function of demographics, previous events and co-morbidities using zero-inflated binomial negative regression. Similarly, time until return to work was analyzed using Cox regression. Results: A total of 2056 patients with DVT were recruited, with an average age of 60 years. Patients with active cancer were mostly treated with heparin (83.9%), while patients without active cancer were treated with combinations of heparin, VKA and DOACs. DOACs were less often used in Spain and Italy (30% did not return to work within the year. Conclusions: Medical treatment of DVT differed between patients with active cancer and those without. Post-VTE or VTE-related resource utilization differs remarkably between countries. Work-loss seems high, but questions may be raised concerning the causality due to the presence of co-morbidities

Pulmonary embolism in Europe - Burden of illness in relationship to healthcare resource utilization and return to work

Objectives Pulmonary embolism (PE) is associated with a substantial economic burden. However evidence from patients in Europe is scarce. The aim of this study was to report the impacts of PE on healthcare resource utilization (HCRU) and return to work using the PREFER in VTE registry. Methods The PREFER in VTE registry was a prospective, observational, multicenter study in seven European countries, aiming to provide data concerning treatment patterns, HCRU, mortality, quality of life and work-loss. Patients with a first-time or recurrent PE were included and followed up at 1, 3, 6 and 12 months. Treatment patterns, re-hospitalization rates, length of hospital stays (LOS), and ambulatory/office visits, as well as proportion of patients returning to work, were assessed. Subgroups by country and with/without active cancer were examined separately. Zero-inflated negative binomial and Cox regression were applied to investigate the relationship between baseline characteristics and LOS and return to work, respectively. Results Amongst 1399 patients with PE, 53.2% were male and the average age was 62.3 ± 17.1 years old. Overall, patients were treated with combinations of heparin, vitamin K antagonists (VKA) and the non-VKA oral anticoagulants (NOACs) (50.0% treated with the combination of heparin with VKA). Patients with active cancer were primarily treated with heparin (84.9%). NOACs were used more frequently in DACH (Germany, Austria and Switzerland) and France (55.2% and 32.6%) compared to Italy and Spain (4.5% and 6.1%). The VTE-related re-hospitalization rate within 12 months and the average LOS varied substantially between countries, from 26.2% in UK to 12.3% in France, and from 12.9 days in Italy to 3.9 days in France. PE patients were often co-managed by general practitioners in France and DACH (>84%), and less frequently in other countries (<47%). The regression results confirmed the country variation of HCRU. Of the employed patients (n = 385), 60% returned to work at 1 month but 27.8% had not after one year. PE patients with DVT were more likely to return to work. Active cancer was a significant predictor for not returning to work, as well as smoking history. Conclusions Medical treatment of PE differed between patients with active cancer and patients without active cancer. VTE-related resource utilization differed markedly between countries. While the reported ’not return to work’ was high for patients with PE, this may at least in part reflect the presence of co-morbidities such as cancer

Health-related quality of life and mortality in patients with pulmonary embolism: a prospective cohort study in seven European countries

PURPOSE: Little is known about the quality of life following pulmonary embolism (PE). The aim of the study was to assess the 12-month illness burden in terms of health-related quality of life (HrQoL) and mortality, in relation to differences in patient characteristics. METHODS: The PREFER in VTE registry, a prospective, observational study conducted in seven European countries, was used. Within 2 weeks following an acute symptomatic PE, patients were recruited and followed up for 12 months. Associations between patient characteristics and HrQoL (EQ-5D-5L) and mortality were examined using a regression approach. RESULTS: Among 1399 PE patients, the EQ-5D-5L index score at baseline was 0.712 (SD 0.265), which among survivors gradually improved to 0.835 (0.212) at 12 months. For those patients with and without active cancer, the average index score at baseline was 0.658 (0.275) and 0.717 (0.264), respectively. Age and previous stroke were significant factors for predicting index scores in those with/without active cancer. Bleeding events but not recurrences had a noticeable impact on the HrQoL of patients without active cancer. The 12-month mortality rate post-acute period was 8.1%, ranging from 1.4% in Germany, Switzerland, and Austria to 16.8% in Italy. Mortality differed between patients with active cancer and those without (42.7% vs. 4.7%). CONCLUSION: PE is associated with a substantial decrease in HrQoL at baseline which normalizes following treatment. PE is associated with a high mortality rate especially in patients with cancer, with significant country variation. Bleeding events, in particular, impact the burden of PE

Analysis of volume and topography of adipose tissue in the trunk: Results of MRI of 11,141 participants in the German National Cohort

This research addresses the assessment of adipose tissue (AT) and spatial distribution of visceral (VAT) and subcutaneous fat (SAT) in the trunk from standardized magnetic resonance imaging at 3 T, thereby demonstrating the feasibility of deep learning (DL)-based image segmentation in a large population-based cohort in Germany (five sites). Volume and distribution of AT play an essential role in the pathogenesis of insulin resistance, a risk factor of developing metabolic/cardiovascular diseases. Cross-validated training of the DL-segmentation model led to a mean Dice similarity coefficient of >0.94, corresponding to a mean absolute volume deviation of about 22 ml. SAT is significantly increased in women compared to men, whereas VAT is increased in males. Spatial distribution shows age- and body mass index-related displacements. DL-based image segmentation provides robust and fast quantification of AT (≈15 s per dataset versus 3 to 4 hours for manual processing) and assessment of its spatial distribution from magnetic resonance images in large cohort studies
