The aim of this study was to determine the survival of patients after use of paclitaxel coated devices (PCX), as a recent meta-analysis of randomised trials reported higher mortality in patients treated with PCX balloons and stents METHODS: A retrospective health insurance claims analysis of patients covered by the second largest insurance fund in Germany, BARMER, was used to identify index femoropopliteal arterial interventions between 1 January 2010 and 31 December 2018. To ensure first PCX exposure, patients with prior deployment of PCX were excluded. The study cohort was stratified into patients with chronic limb threatening ischaemia (CLTI) and intermittent claudication (IC), then into balloons vs. stents cohorts. Within each stratum PCX were compared with uncoated devices. Propensity score matching was used to balance the study groups. Survival was evaluated using the Kaplan-Meier method and Cox regression. There were 37 914 patients (mean age 73.3 years; 48.8% female) included in the study. The annual proportion of PCX use increased from 3% to 39% during the study period for CLTI and from 4% to 48% for IC (both p < .001). Paclitaxel coated balloons and stents were associated with improved overall survival (hazard ratio [HR] 0.83, 95% confidence interval [CI] 0.77-0.90), amputation free survival (HR 0.85, 95% CI 0.78-0.91), and freedom from major cardiovascular events (HR 0.82, 95% CI 0.77-0.89) vs. uncoated devices at five years for CLTI. In IC cohort, mortality was significantly lower after using drug coated balloons (DCB) (HR 0.87, 95% CI 0.76-0.99) or combined DCB and drug eluting stents (HR 0.88, 95% CI 0.80-0.98). In this large health insurance claims analysis, rapid adoption of PCX, higher long term survival, better amputation free survival, and lower rates of major cardiovascular events were seen after their use for the treatment of CLTI.

Patients suffering from peripheral arterial occlusive disease (PAOD) are a central target population for multidisciplinary vascular medicine. This study aimed to highlight trends in treatment patterns and comorbidities using up to date longitudinal patient related data from Germany. This study is a retrospective health insurance claims data analysis of patients insured by the second largest health insurance provider in Germany, BARMER. All PAOD patient hospitalisations between 2008 and 2016 were included. The comorbidities were categorised with Elixhauser groups using WHO ICD-10 codes and summarised as the linear van Walraven score (vWS). A trend analysis of the comorbidities was performed after standardisation by age and sex. A total of 156 217 patients underwent 202 961 hospitalisations (49.4% for chronic limb threatening ischaemia in 2016) with PAOD during the study period. Although the estimated annual incidence of PAOD among the BARMER cohort decreased slightly (- 4.4%), an increase was observed in the prevalence of PAOD (+ 23.1%), number of hospitalisations (+ 25.1%), peripheral vascular interventions (PVI, + 61.1%), and disease related reimbursement costs (+ 31%) from 2008 to 2016. Meanwhile, the number of major amputations decreased (- 15.1%). The proportion of patients aged 71-80 years increased about +10% among PAOD patients and the mean vWS also increased by two points during the study period. Considerable increases were found in the rates of hypertension, renal failure, and hypothyroidism, whereas the rates of diabetes and congestive heart failure decreased over time. Increasing numbers of PVI performed on these ageing and sicker patients lead to rising costs but correlate with decreasing major amputation rates.

Background Smoking contributes to socioeconomic inequalities in mortality, but the extent to which this contribution has changed over time and driven widening or narrowing inequalities in total mortality remains unknown. We studied socioeconomic inequalities in smoking-attributable mortality and their contribution to inequalities in total mortality in 1990–1994 and 2000–2004 in 14 European countries. Methods We collected, harmonised and standardised population-wide data on all-cause and lung-cancer mortality by age, gender, educational and occupational level in 14 European populations in 1990–1994 and 2000–2004. Smoking-attributable mortality was indirectly estimated using the Preston-Glei-Wilmoth method. Results In 2000–2004, smoking-attributable mortality was higher in lower socioeconomic groups in all countries among men, and in all countries except Spain, Italy and Slovenia, among women, and the contribution of smoking to socioeconomic inequalities in mortality varied between 19% and 55% among men, and between −1% and 56% among women. Since 1990–1994, absolute inequalities in smoking-attributable mortality and the contribution of smoking to inequalities in total mortality have decreased in most countries among men, but increased among women. Conclusions In many European countries, smoking has become less important as a determinant of socioeconomic inequalities in mortality among men, but not among women. Inequalities in smoking remain one of the most important entry points for reducing inequalities in mortality.

There is a paucity of current figures on the prevalence of carotid and lower extremity peripheral arterial disease (PAD) and abdominal aortic aneurysm (AAA) as well as the associated cardiovascular risk factors to support considerations on screening programmes. In the population based Hamburg City Health Study, participants between 45 and 74 years were randomly recruited. In the current cross sectional analysis of the first 10 000 participants enrolled between February 2016 and November 2018, the prevalence of carotid artery disease (intima-media thickness ≥ 1 mm), lower extremity PAD (ankle brachial index ≤ 0.9), and AAA (aortic diameter ≥ 30 mm) was determined. Multivariable logistic regression models were applied to determine the association between vascular diseases and risk factors. To account for missing values, multiple imputation was performed. A total of 10 000 participants were analysed (51.1% females, median age 63 years, median body mass index 26.1 kg/m2). In medians, the intima media thickness was 0.74 mm (interquartile range [IQR] 0.65 - 0.84), the ankle brachial index 1.04 (IQR 0.95 - 1.13), and the aortic diameter 17.8 mm (IQR 16.1 - 19.6). Concerning risk factors, 64% self reported any smoking, 39% hypertension, 5% coronary artery disease, 3% congestive heart failure, 5% atrial fibrillation, and 3% history of stroke or myocardial infarction, respectively. In males, the prevalence of carotid artery disease, lower extremity PAD, and AAA were 35.3%, 22.7%, and 1.3%, respectively, and in females, 23.4%, 24.8%, and 0.2%, respectively. Higher age and current smoking were likewise associated with higher prevalence while the impact of variables varied widely. In this large population based cohort study of 10 000 subjects from Hamburg, Germany, a strikingly high prevalence of PAD was revealed. Almost 45% suffered from any index disease, while AAA was only diagnosed in 1.3% of males and 0.2% of females. The high prevalence of atherosclerotic disease and associated cardiovascular risk factors underline that it is essential to increase awareness and fuel efforts for secondary prevention.

Patients with peripheral arterial occlusive disease (PAOD) face an increased risk of both lower limb amputation and death. To date, it has been challenging to predict the long term outcomes for PAOD. The aim was to develop a risk score to predict worse five year amputation free survival (AFS). In this retrospective analysis of claims data, symptomatic PAOD patients were split into training and validation sets. Variables in the model were patient age and sex, Elixhauser comorbidities, and the 190 most common secondary diagnoses. Penalised Cox regression (least absolute shrinkage and selection operator [LASSO]) with tenfold cross validation for variable selection was performed and patients were categorised into five risk groups using the ten most important variables. All analyses were stratified by intermittent claudication (IC) and chronic limb threatening ischaemia (CLTI). In total, 87 293 patients with PAOD (female 45.3%, mean age 71.4 ± 11.1 years) were included in the analysis. The most important variable predicting worse five year AFS was patient age >80 years. The GermanVasc score exhibited good predictive accuracy both for IC (c statistic = 0.70, 95% confidence interval [CI] 0.69-0.71) and CLTI (c statistic = 0.69, 95% CI 0.68-0.70) with adequate calibration due largely to alignment of observed and expected risk. Depending on the cumulative point score, the five year risk of amputation or death ranged from 9% (low risk) to 48% (high risk) for IC, and from 25% to 88% for CLTI. The GermanVasc score predicts worse five year AFS stratified for inpatients suffering from IC and CLTI, with good predictive accuracy. By separating low from high risk patients, the GermanVasc score may support patient centred consent.
