      Non-alcoholic steatohepatitis (NASH) leads to cirrhosis and is associated with a substantial socioeconomic burden, which, coupled with rising prevalence, is a growing public health challenge. However, there are few real-world data available describing the impact of NASH. The Global Assessment of the Impact of NASH (GAIN) study is a prevalence-based burden of illness study across Europe (France, Germany, Italy, Spain, and the UK) and the USA. Physicians provided demographic, clinical, and economic patient information via an online survey. In total, 3,754 patients found to have NASH on liver biopsy were stratified by fibrosis score and by biomarkers as either early or advanced fibrosis. Per-patient costs were estimated using national unit price data and extrapolated to the population level to calculate the economic burden. Of the patients, 767 (20%) provided information on indirect costs and health-related quality of life using the EuroQOL 5-D (EQ-5D; n = 749) and Chronic Liver Disease Questionnaire - Non-Alcoholic Fatty Liver Disease (CLDQ-NAFLD) (n = 723). Mean EQ-5D and CLDQ-NAFLD index scores were 0.75 and 4.9, respectively. For 2018, the mean total annual per patient cost of NASH was €2,763, €4,917, and €5,509 for direct medical, direct non-medical, and indirect costs, respectively. National per-patient cost was highest in the USA and lowest in France. Costs increased with fibrosis and decompensation, driven by hospitalisation and comorbidities. Indirect costs were driven by work loss. The GAIN study provides real-world data on the direct medical, direct non-medical, and indirect costs associated with NASH, including patient-reported outcomes in Europe and the USA, showing a substantial burden on health services and individuals. There has been little research into the socioeconomic burden associated with non-alcoholic steatohepatitis (NASH). The GAIN study provides real-world data on the direct medical, direct non-medical, and indirect costs associated with NASH, including patient-reported outcomes in five European countries (UK, France, Germany, Spain, and Italy) and the USA. Mean total annual per patient cost of NASH was estimated at €2,763, €4,917, and €5,509 for the direct medical, direct non-medical, and indirect cost categories, respectively.

    • Prophylactic Treatment in People with Severe Hemophilia B in the US: An Analysis of Real-World Healthcare System Costs and Clinical Outcomes

      Introduction The treatment paradigm for people with severe hemophilia B in the US typically involves prophylaxis with factor IX (FIX) replacement therapy, the primary aim of which is to provide sufficient FIX levels to reduce the frequency of bleeding events. The clinical benefits of FIX prophylaxis are well understood, however the cost of FIX products as well as costs associated with healthcare resource utilization present a significant burden to the healthcare system. Substantive costs may also accrue in patients who continue to bleed while on prophylaxis, due to the impact on both short and long-term joint-related outcomes. In the absence of existing data in the US, the 'Cost of Hemophilia Across the USA: a Socioeconomic Survey' (CHESS US) study was conducted to establish a population-based estimate of the real-world US healthcare system burden associated with severe hemophilia. Using data drawn from the CHESS US study, this analysis examines the real-world healthcare system costs and clinical outcomes of people with severe hemophilia B on FIX prophylaxis. Methods CHESS US, a retrospective, cross-sectional dataset of adults with severe hemophilia in the USA, gathered information on patient cost via a patient record form. Data on the following parameters are included in this analysis: FIX consumption, annualized bleeding rate (ABR), the presence of one or more chronically damaged joints ("problem joint"), as well as costs associated with annual (prophylactic) factor consumption and hospitalizations (i.e., number of admissions, number of day cases, total inpatient days, and total intensive care unit [ICU] days). All variables report retrospective data of the 12 months prior to enrolment in the study. Results are presented as mean (± standard deviation) or N (%). Results In total, 132 of 576 patients profiled in the CHESS US study had severe hemophilia B. Among them, 77 patients were on FIX prophylaxis, of whom 44 patients reported FIX dosing regimen and were included in the current analyses. Among them, 20 patients were treated with conventional FIX and 24 patients with extended half-life (EHL) FIX products. The cohort has a mean age of 27.64 (± 11.05) and mean weight (kg) of 75.71 (± 13.41). In the last 12 months, the mean number of international units (IU) prescribed for FIX prophylaxis across the full cohort was 257,216 IU (± 213,591), with an associated annual cost of $610,966 (± $495,869). Among patients treated with conventional FIX, mean prescribed FIX was 287,141 IU (± 264,906) at an annual cost of $397,491 (± $359,788), while patients treated with EHL FIX reported a mean prescribed FIX of 232,278 IU (± 160,914) at an annual cost of $788,861 (± $529,258). The cohort reported a mean ABR of 1.73 (± 1.39); 8 (18%) were reported to have a target joint meeting the International Society on Thrombosis and Haemostasis (ISTH) definition; and 11% were reported to have had at least one chronically damaged joint (i.e., problem joint). Healthcare resource utilization associated with bleed events were reported as follows: hospital admissions days [0.18 (± 0.62)]; inpatient days [0.34 (± 1.22)]; and ICU days [0.23 (± 0.86)]. The direct medical cost to the healthcare system was $2,885 (± $7,857; excluding FIX cost) and $614,886 (± $498,839; including FIX cost). Discussion Data from the CHESS US study showed substantial costs and resource utilization among patients with severe hemophilia B receiving FIX prophylaxis, of which the cost of FIX replacement therapy constituted most of the total cost to healthcare system. Although the ABR observed in the analysis population was low, bleed-related hospitalizations comprised a significant non-drug cost to the healthcare system. A proportion of patients also still experienced joint arthropathy. Such substantial clinical and economic burden highlights that unmet needs remain in patients with severe hemophilia B on FIX prophylaxis in the US. Disclosures Noone: HCD Economics: Employment.

      Background. Some studies suggest that people with haemophilia (PwH) who use prophylaxis value low frequency of clotting factor administration more than a lower risk of bleeding. However, more frequent infusions offer the potential of reducing joint disease and pain, which in turn may improve functioning and quality of life.AimsTo explore the impact on health-related quality of life (HRQoL) aspects of haemophilia associated with adherence and annual infusion rate in the context of factors influencing treatment that are important to patients, including prophylaxis, chronic pain, concomitant conditions and hospital admission.Materials and methodsHRQoL was assessed in participants with severe haemophilia in the ‘Cost of Haemophilia in Europe: a Socioeconomic Survey’ (CHESS) study who were using prophylaxis. Patients using on-demand treatment were excluded. This multivariate analysis examined the interaction between factors potentially influencing treatment and HRQoL, and minor and major bleeds.ResultsFrom the total CHESS population (n=1,285), 338 (26%) participants provided responses for major and minor bleeds and target joints, and 145 (11%) provided EQ-5D-3L responses. Major and minor bleeds were associated with pain. Patients with severe chronic pain reported a substantial negative impact on HRQoL; but this was significantly improved by increases in the annual infusion rate. This was not apparent in participants with mild or moderate pain.ConclusionIncreasing the frequency of prophylaxis infusions is associated with improved quality of life in PwH who have severe chronic pain. However, increasing the number of infusions per week in those with mild or moderate chronic pain with the intention of improving prophylactic effect may not have the same effect.
