Abstract
BACKGROUND & AIMS With long-term consequences like the development of liver cirrhosis and hepatocellular carcinoma, chronic hepatitis C virus (HCV) infection is associated with a significant health burden. Information on HCV treatment outcomes and costs in routine care is still rare, especially for subgroups. The aim of this study was to analyse the treatment outcomes and costs of subgroups in routine care and to compare them over time with previous analyses. METHODS Data were derived from a noninterventional study including a subset of 10298 patients receiving DAAs with genotypes 1 and 3. Sociodemographic, clinical parameters and costs were collected using a web-based data recording system. The total sample was subdivided according to treatment regimen, cirrhosis status as well as present HIV infection and opioid substitution treatment (OST). RESULTS 95% of all patients achieved SVR. Currently used DAA showed higher SVR-rates and less adverse events (AE) compared to former treatments. Concerning subgroups, cirrhotic patients, HIV-coinfected patients and OST patients showed lower but still high SVR-rates. In comparison, cirrhotic had considerably longer treatment duration and more frequent (serious) AE. Overall, average treatment costs were €48470 and costs per SVR were €51129; for currently used DAAs costs amounted to €30330 and costs per SVR to €31692. After the end of treatment, physical health is similar to the general population in all patients except cirrhotic. Mental health remains far behind in all subgroups, even for currently used DAA. CONCLUSIONS Over time, some relevant factors developed positively (SVR-rates, costs, treatment duration, adverse events, health-related quality of life (HRQoL)). Further research on HRQoL, especially on mental health, is necessary to evaluate the differences between subgroups and HRQoL over time and to identify influencing factors.

Abstract
Background Hepatitis C infections (HCV) are associated with an increase in morbidity and mortality. The aim of this study is to update the results of treatment with direct-acting antiviral agents (DAAs) using a larger population of healthcare personnel (HP) and a longer observation period. Methods Secondary data analysis of DAA treatment administered to HP (with confirmed occupational acquired HCV infection) between 1 January 2014 and 30 December 2018, is based on statutory accident insurance data from Germany. The end points of the study were results of a monitoring carried out 12 and 24 weeks after the end of treatment (sustained virological response, SVR), as well as side effects and the assessment of reduced work ability after treatment. Multivariate logistic regression models were constructed to investigate predictors of SVR. Results The study population (n = 305) mainly comprised HP with a genotype 1 infection. The average age was 63 (SD 10) and 77% were female. Two thirds of the HP suffered from fibrosis or cirrhosis, and had experience of treatment. Statistically, men were significantly more likely to suffer from cirrhosis than women (60% compared to 21%, p < 0.001). The end-of-treatment response (ETR) rate was 99% and the SVR12 and SVR24 rates were 98%. Liver cirrhosis proved to be a predictor of a statistically significant reduction in success rates. Conclusion DAA treatment leads to high SVR. Early HCV treatment is associated with higher SVR.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:E440. [PMID: 31936470 PMCID: PMC7013637 DOI: 10.3390/ijerph17020440] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/07/2019] [Revised: 01/03/2020] [Accepted: 01/06/2020] [Indexed: 02/07/2023]
Abstract
Around 1% of the world's population is infected with hepatitis C. The introduction of new direct-acting antiviral agents (DAAs) in 2014 has substantially improved hepatitis C treatment outcomes. Our objective was to evaluate the long-term cost effectiveness of DAAs in health care personnel (HP) with confirmed occupational diseases in Germany. A standardised database from a German statutory accident insurance was used to analyse the cost-effectiveness ratio for the DAA regimen in comparison with interferon-based triple therapies. Taking account of the clinical progression of the disease, a Markov model was applied to perform a base case analysis for a period of 20 years. The robustness of the results was determined using a univariate deterministic sensitivity analysis. The results show that treatment with DAAs is more expensive, but also more effective than triple therapies. The model also revealed that the loss of 3.23 life years can be averted per patient over the 20 years. Compared to triple therapies, DAA treatment leads to a higher sustained virologic response (SVR). Although this results in a decrease of costs in the long term, e.g., pension payments, DAA therapy will cause greater expense in the future due to the high costs of the drugs.

Abstract
BACKGROUND Veterans with hepatitis C virus (HCV) infection may face geographic obstacles to obtaining treatment. OBJECTIVE We studied the influence of region and rural versus urban residence on receipt of direct-acting antiretroviral (DAA) medications for HCV. SUBJECTS Veterans receiving care within Veterans Affairs Healthcare System born between 1945 and 1965. RESEARCH DESIGN This is a observational study using national electronic health record data. MEASURES Receipt of DAAs was defined as ≥1 filled prescription from January 1, 2014 to December 31, 2016. Region (South, Northeast, Midwest, and West) and residence (urban, rural-micropolitan, small rural towns, and isolated rural towns) variables were created using residential zone improvement plan codes and rural-urban commuting area (RUCA) codes. Multivariable models were adjusted for age, race, sex, severity of liver disease, comorbidities, and prior treatment experience. RESULTS Among 166,353 eligible patients 64,854 received, DAAs. Variation by rural-urban residence depended on region. In unadjusted analyses, receipt varied by rural-urban designations within Midwest, and West regions (P<0.05) but did not vary within the South (P=0.12). Southern rural small town had the lowest incidence of DAA receipt (40.1%), whereas the incidence was 52.9% in Midwestern isolated rural towns. In adjusted logistic analyses, compared with southern urban residents (the largest single group), southern rural small town residents had the lowest odds ratio, 0.85 (95% confidence interval, 0.75-0.93), and Midwestern residents from isolated and small rural towns had the highest odds (odds ratio, both 1.27) to receive treatment. CONCLUSIONS Substantial geographic variation exists in receipt of curative HCV treatment. Efforts are needed to provide more equitable access to DAAs.

Abstract
OBJECTIVE Chronic hepatitis C virus infection is associated with a significant health burden. Long-term consequences are the development of liver cirrhosis and hepatocellular carcinoma. The introduction of direct-acting antivirals (DAA) has led to an increase in sustained virologic response rates (SVR), but is accompanied by higher treatment costs. The aim of this study was to assess the outcomes and costs of treating hepatitis C virus infected patients with DAAs in clinical practice in Germany. PATIENTS AND METHODS Data were derived from a noninterventional study including a pharmacoeconomic subset of 2673 patients with genotypes 1 and 3 who initiated and completed treatment between February 2014 and February 2017. Sociodemographic and clinical parameters as well as resource utilization were collected using a web-based data recording system. Costs were calculated using official remuneration schemes. RESULTS The mean age of the patients was 54.6 years; 48% were men. 93.5% of all patients achieved an SVR. The average total treatment costs were &OV0556;67 979 (&OV0556;67 131 medication costs, &OV0556;824 ambulatory care, &OV0556;24 hospital costs). The average costs per SVR of &OV0556;72 705 were calculated. Differences in SVR and costs according to genotype, treatment regimen, treatment experience, and cirrhosis were observed. Quality-of-life data showed no or a minimal decrease during treatment. CONCLUSION This analysis confirms high SVR rates for newly introduced DAAs in a real-world setting. Costs per SVR estimated are comparable to first-generation DAA. Given the fact that the costs for the currently used treatment regimens have declined, it can be assumed that the costs per SVR have also decreased. Our insight into real-world outcomes and costs can serve as a basis for a comparison with the mentioned newly introduced treatment regimens.

Abstract
Background Hepatitis C Virus (HCV) infections are blood-borne, generally chronic and are associated with increased morbidity and mortality. The aim of this study is to describe the results of therapies with direct-acting antiviral agents (DAAs) in healthcare personnel. Methods Secondary data analysis using data from the Statutory Accident Insurance of the Health and Welfare Service. The study surveyed DAA therapies administered to insured parties (healthcare personnel with an HCV infection recognised as an occupational disease) in Germany between 01/01/2014 and 30/11/2016. The end points were results of monitorings carried out twelve weeks after the end of treatment (SVR12), side effects and the results of the assessment of reduced work ability after treatment. Multivariate logistic regression models were constructed to model SVR12. Results The study population (n = 180) comprised 74% women, 90% of the participants had an HCV genotype 1 infection. Two-thirds had fibrosis or cirrhosis and were treatment experienced. The most common combined therapy was ledipasvir and sofosbuvir (49%). A DAA therapy with ribavirin was administered in 20% of cases, with (pegylated) interferon and ribavirin used in 2% of cases. The majority of therapies were completed without any side effects. The overall SVR12 rate was 94%. Significant independent predictor of decrease odds of SVR12 was liver cirrhosis. Positive effects on the healthcare personnel’s work ability were observed after successful therapy. Conclusion High SVR12 rates were achieved in the sample population, with positive effects on their work ability. Early HCV therapy seems reasonable due to the increased chance of successful treatment of the infection.

Abstract
Background Chronic hepatitis C remains a major global health burden with serious long-term consequences if left untreated. Recently the treatment standard of care has shifted to new interferon (IFN)-free drug regimens, which have been shown to be safe and effective. The aim of our study was to assess and compare medical resource utilization and costs of successfully treating patients with IFN-based and IFN-free therapies in Australia. Methods We performed a retrospective chart review of 30 HCV-infected patients successfully treated with IFN-based therapy between 2013 and 2015. We also generated a model for a virtual group of 100 genotype 1 (GT1) and 100 genotype 3 (GT3) patients treated with IFN-free therapy derived from national guidelines and clinical trial data. Results In comparison to virtual patients receiving IFN-free therapy, our IFN-treated patients on average had distinctively more liver clinic visits and blood tests. However, mean total cost per patient was $19,164 and $85,300 (AUD) more for GT1 and GT3 patients receiving IFN-free therapy, respectively. This difference was largely accounted for by higher antiviral drug costs. Of our 30 patients treated with IFN, total mean cost per patient during the study period was $33,595. Conclusion Resource utilization is lower with IFN-free treatment, which reflects the reduced need for patient monitoring and improved side-effect profile of these new drugs. However, total costs are still largely dominated by antiviral drug costs, representing a huge burden on national budgets. Our insight into resource utilization and costs associated with both types of treatment can serve as a reference for future studies.

Abstract
1 OBJECTIVE Chronic hepatitis C virus infections (HCV) cause a significant public health burden. Introduction of telaprevir (TVR) and boceprevir (BOC) has increased sustained virologic response rates (SVR) in genotype 1 patients but were accompanied by higher treatment costs and more side effects. Aim of the study was to assess outcomes and costs of treating HCV with TVR or BOC in routine care. 2 MATERIAL AND METHODS Data was obtained from a non-interventional study. This analysis relates on a subset of 1,786 patients for whom resource utilisation was documented. Sociodemografic and clinical parameters as well as resource utilisation were collected using a web-based data recording system. Costs were calculated using official remuneration schemes. 3 RESULTS Mean age of patients was 49.2 years, 58.6% were male. In treatment-naive patients SVR-rates of 62.2% and 55.7% for TVR and BOC were observed (prior relapser: 68.5% for TVR and 63.5% for BOC; prior non-responder: 45.6% for TVR and 39.1% for BOC). Treatment costs are dominated by costs for pharmaceuticals and range between €39,081 and €53,491. We calculated average costs per SVR of €81,347 (TVR) and €70,163 (BOC) in treatment-naive patients (prior relapser: 78,089 €/SVR for TVR and 82,077 €/SVR for BOC; prior non-responder: 116,509 €/SVR for TVR and 110,156 €/SVR for BOC). Quality of life data showed a considerable decrease during treatment. 4 CONCLUSION Our study is one of few investigating both, outcomes and costs, of treating HCV in a real-life setting. Data can serve as a reference in the discussion of increasing costs in recently introduced agents.
