Abstract:We conducted an international study to evaluate practices in the diagnosis and management of patients with chronic thromboembolic pulmonary hypertension (CTEPH) globally across different regions. Between August and October 2012, CTEPH-treating physicians completed a 15-minute online questionnaire and provided patient record data for their 2-5 most recent patients with CTEPH. Overall, 496 physicians (Europe: 260; United States: 152; Argentina: 52; Japan: 32) completed the questionnaire and provided patient record data for 1,748 patients. The proportion of physicians who described themselves as working in or affiliated with a specialized pulmonary hypertension (PH) center ranged from 38% in France and Italy to 83% in the United States. A large proportion of patients did not undergo ventilation/perfusion scanning (46%-67%) or right heart catheterization (24%-57%) for the diagnosis of CTEPH. Referral rates for pulmonary endarterectomy evaluation ranged from 25% in Japan to 44% in Europe, with higher referral rates in PH centers; the main reasons for lack of referral were that surgery was not considered unless medical treatment was failing and patient refusal. Other variations in management included greater use of phosphodiesterase 5 inhibitors in the United States than in Europe and Japan and greater use of combination treatment in the United States than in Europe. Physicians' perceptions of their treatment strategy were generally consistent with patient record data. Results from this study, which includes a global aspect of CTEPH care, demonstrate not only regional differences in CTEPH management but, more importantly, considerable nonadherence to the diagnosis and treatment guidelines for CTEPH, even in PH centers.Keywords: chronic thromboembolic pulmonary hypertension, pulmonary arterial hypertension-specific therapies, diagnosis, clinical practice, guidelines. Chronic thromboembolic pulmonary hypertension (CTEPH) is a disease of obstructive pulmonary artery remodeling as a consequence of major vessel thromboembolism. 1 A ventilation/perfusion (V/Q) scan is recommended in the workup of all patients with pulmonary hypertension (PH) to screen for CTEPH. 1 Diagnosis of CTEPH is challenging for several reasons, including nonspecific presenting symptoms, which may occur late in the progression of the disease, and a lack of prior pulmonary embolism in a high percentage of patients. 2 Once CTEPH is diagnosed, pulmonary endarterectomy (PEA) is the gold-standard treatment for these patients and is potentially curative. 1,3 However, between 20% and 40% of these patients are considered to have inoperable CTEPH, 4 and approximately 30% may have residual PH after PEA (defined as mean pulmonary artery pressure of ≥30 mmHg at 3-month follow-up after surgery). 5 Balloon pulmonary angioplasty (BPA) is an emerging treatment option for patients with inoperable or persistent CTEPH. 3 However, the role of BPA in CTEPH has not been investigated in randomized trials, and further studies are warranted; current guidelines state ...

Abstract:We conducted an international study to evaluate practices in the diagnosis and management of pulmonary arterial hypertension (PAH) globally across different geographic regions. Between July and October 2012, PAH-treating physicians completed a 15-minute online questionnaire and provided patient record data for their 3 or 5 most recent patients with PAH. Overall, 560 physicians (Europe: 278; United States: 160; Argentina: 53; Japan: 69) completed the questionnaire and provided data for 2,618 patients. The proportion of physicians who described themselves as working in or affiliated with a specialized pulmonary hypertension center ranged from 13% in Argentina to 74% in the United States. At the time of diagnosis, patients' New York Heart Association functional class differed significantly between regions. At the time of last assessment, functional class had improved overall, and differences between regions had largely disappeared. A large proportion of patients did not undergo right heart catheterization for the diagnosis of PAH (Europe: 7%-21%; United States: 21%; Japan: 19%; Argentina: 51%). Variations in management included greater use of phosphodiesterase 5 inhibitors in the United States than in Europe and Japan and greater use of triple or greater combination therapy in Japan than in other regions. Results from this study, which includes a global aspect of PAH care, demonstrate that there are significant differences in PAH management between regions and low adherence to guidelines recommending right heart catheterization for the diagnosis of PAH.Keywords: pulmonary arterial hypertension, pulmonary arterial hypertension-specific therapies, diagnosis, clinical practice, guidelines. Pulmonary arterial hypertension (PAH; World Health Organization group I) is defined by a mean pulmonary artery pressure of ≥25 mmHg and increased pulmonary vascular resistance of >3 Wood units with a normal pulmonary capillary wedge pressure. 1,2 PAH is a progressive disease that can ultimately lead to right heart failure and death. 1,3 Despite advances in current therapies for PAH, there is still significant unmet medical need, especially in areas of the world where access to diagnostic and therapeutic options is limited. The mortality of patients with PAH remains high even in well-developed countries: 15% at 1 year and 32% at 3 years. 4 The therapeutic approach to PAH is evolving; multiple classes of agents are available, and physicians from both expert pulmonary hypertension (PH) centers and the community treat patients with PAH. 5,6 Data from various registries suggest that approaches to the diagnosis and treatment of PAH may differ between countries. [7][8][9][10][11] In this international study, we sought to assess differences in the diagnosis and management of patients with PAH across different countries and regions worldwide by conducting a large, physicianbased study using a quantitative online questionnaire. The objectives of the study were (1) to assess the diagnosis and management of PAH in different countries a...

L) or LDL-C .300 mg/dL (8 mmol/L) under treatment with statins and/or 1 or both parents having clinically diagnosed FH. For the projection of the estimated prevalence of FH to the population of the Colombian Caribbean, the data of the adult population projections for the Colombian Caribbean of 2015 (general 10,442,134, adults 6,685,734) of the Departamento Administrativo Nacional de Estadisticas (DANE) were used. Results: If we assume that 1 of 5 patients with LDL-C .190 mg/dL (5 mmol/L) may have HF. The prevalence of patients with FH was 0.13% (87/64,667). The prevalence of adults with heterozygous FH (FHHe) was 0.13% (85/64,639). The prevalence of adults with homozygous HF (FHHo) was 0.0015% (1/64,639). Applying these estimates to the general population of Colombian Caribbean in 2015, the estimated number of cases of HF, FHHe and FHHo in the Caribbean Colombian could be approximately 13,574, 8,691 and 140, respectively. Conclusions: The estimated prevalence of FH, FHHe and FHHo in Colombian Caribbean was 1 of 769, 1 of 769 and 2 of 100,000 patients, respectively.

Background and Aims: Non-alcoholic steatohepatitis (NASH) is acknowledged as a severe disease that is associated with a significant burden on patients, payers, and society. However, limited evidence exists on the cost associated with NASH across different countries. This analysis aims to describe the cost associated with the routine care of patients with NASH in France, Germany, and the United States. Methods: Data was sourced from the Gesellschaft für Konsumforschung (now Ipsos) Disease Atlas Real- World Evidence program collected from July through November 2017 in France, Germany, and the United States. Country-level unit cost was estimated from national databases for diagnostic tests and procedures, prescription drugs, hospital stays, and outpatient visits in respective local currency based on 2017 values. These were combined to provide an estimate of the cost of management of confirmed NASH in this specific patient population and are presented as mean cost per patient per year for each country in local currency and as USD adjusted for purchasing power parity for comparison. Results: Annual mean ± standard deviation cost of non-alcoholic steatohepatitis ranged from purchasing power parity USD 1,049±2,461 in Germany to USD 1,723±2,988 in the United States. In all markets, the predominant contributor to cost is healthcare resource use represented by hospitalisation and outpatient visits. Conclusions: This study reveals that costs associated with NASH treatment and management vary across the three countries studied, in part due to differences in healthcare systems but also due to different approaches in managing this disease. Our analysis represents the costs for a specific cohort of patients and further studies are warranted to better understand the progressive impact of NASH on healthcare systems and society.

Background Prescription of Non-vitamin K oral anticoagulants (NOACs) has increased since the first therapies were launched in Europe in 2011, and they are becoming the standard of care in prevention of stroke in patients with non-valvular atrial fibrillation (NVAF). There are concerns about inappropriate NOAC dosing in clinical practice. Purpose This paper examines the extent of inappropriate dose prescription among NOAC patients in Germany, Italy, Spain and United Kingdom. Inappropriate dosing refers to patients who do not meet the criteria for dose reduction (under-dose) or patients who should be on the reduced dose as they meet the criteria for dose reduction (overdose). Methods Ipsos' Stroke Prevention in Atrial Fibrillation Therapy Monitor was fielded for 6 weeks between January 2017 to February 2017 and 6 weeks between January 2018 to March 2018, with 450 treating doctors in 2017 and 509 in 2018 providing data from 5,692 (2017: n=2,497, 2018: n=3,195) patients with non-valvular atrial fibrillation in Europe. We analysed the results for the 3,477 patients with a NOAC prescription that had sufficient data to decide on the appropriate dose. Results Overall, 23.4% of patients (n=813) were receiving an inappropriate dose of dabigatran, rivaroxaban, apixaban or edoxaban. Receiving an under-dose was more common than an overdose (19.2% vs 4.2%). Ipsos data indicate 32.8% of NOAC patients in EU4 (n=1,139) were prescribed a reduced dose, and Italy had a higher proportion of patients who received a reduced dosed; Italy: 41.0% (n=345), Germany: 30.2% (n=402), Spain: 30.6% (n=216) and UK: 29.4% (n=176). Among these patients, a considerable proportion did not meet the criteria for dose reduction in EU4 (58.6%). This suggests that reduced dose is frequently prescribed to patients when not indicated. Conclusion Overall, the majority of patients were prescribed a correct dose according to the product label. However, we see evidence that nearly half of patients receiving a reduced dose were not indicated for a dose reduction. Further research is needed to identify reasons prompting the over-use of reduced dose.
