Spending on nucleos(t)ide analogues for hepatitis B in medicaid beneficiaries: 2012-2021.

INTRODUCTION AND OBJECTIVES: Treatment of chronic hepatitis B (CHB) with nucelos(t)ide analogues (NA) can improve outcomes, but NA treatment is expensive for insurance plans. MATERIALS AND METHODS: The Centers for Medicare & Medicaid Services database was assessed from 2012 to 2021 to assess the use of NA for CHB in patients on Medicaid. Data extracted included the number of claims, units, and costs of each agent stratified by originator and generic. RESULTS: Over the study period, 1.9 billion USD was spent on NA, with spending peaking in 2016 at $289 million US, which has subsequently decreased. Lower expenditures since 2016 have been associated with increased use of generics. The use of generic tenofovir or entecavir led to savings of $669 million US over the study period. CONCLUSIONS: Increased generic use has significantly reduced expenditures for NA drugs; policy shifts towards generic drug use may help with sustainability.

Impact of the 2008 economic crisis on the burden of hepatitis B and C diseases in Southern European countries.

BACKGROUND: The economic crisis that began in 2008 has severely affected Southern (Greece, Italy, Portugal, Spain) Western European (SWE) countries of Western Europe (WE) and may have affected ongoing efforts to eliminate viral hepatitis. This study was conducted to investigate the impact of the economic crisis on the burden of HBV and HCV disease. METHODS: Global Burden of Diseases 2019 data were used to analyse the rates of epidemiological metrics of HBV and HCV acute and chronic infections in SWE and WE. Time series modelling was performed to quantify the impact of healthcare expenditure on the time trend of HBV and HCV disease burden in 2000-2019. RESULTS: Declining trends in incidence and prevalence rates of acute HBV (aHBV) and chronic HBV were observed in SWE and WE, with the pace of decline being slower in the post-austerity period (2010-2019) and mortality due to HBV stabilised in SWE. Acute HCV (aHCV) metrics and chronic HCV incidence and mortality showed a stable trend in SWE and WE, whereas the prevalence of chronic HCV showed an oscillating trend, decreasing in WE in 2010-2019 (p < 0.001). Liver cancer due to both hepatitis infections showed a stagnant burden over time. An inverse association was observed between health expenditure and metrics of both acute and chronic HBV and HCV. CONCLUSIONS: Epidemiological metrics for HBV and HCV showed a slower pace of decline in the post-austerity period with better improvement for HBV, a stabilisation of mortality and a stagnant burden for liver cancer due to both hepatitis infections. The economic crisis of 2008 had a negative impact on the burden of hepatitis B and C. Elimination of HBV and HCV by 2030 will be a major challenge in the SWE countries.

[Strategic considerations in health economics for the complete treatment of patients with chronic HBV infection].

The World Health Organization (WHO) released the Global Health Sector Strategy 2016, which explicitly proposes a 90% reduction in the new hepatitis B virus (HBV) infection rate and a 65% reduction in HBV-related mortality by 2030. However, at present, there are still 296 million chronic hepatitis B virus-infected patients worldwide, and nearly 900,000 patients die every year from cirrhosis and liver cancer caused by HBV infection. Antiviral treatment for chronic hepatitis B virus infection can effectively inhibit HBV replication, reduce liver inflammation and necrosis, effectively block and reverse liver fibrosis, and even early cirrhosis, thereby lowering cirrhosis-related complications, liver cancer, and liver disease-related mortality. Although the domestic and foreign guidelines have gradually eased antiviral treatment indications for chronic hepatitis B, there are still a considerable number of chronic hepatitis B patients with nonconformity who cannot receive antiviral treatment because they do not meet the existing standards, resulting in the progression of more severe diseases. This study analyzed the prevalence of hepatitis B, the therapeutic effect of antiviral drugs, domestic and international guideline treatment standards, the assessment of key indicators changes in the guidelines, comprehensively considered the coverage rate and treatment standards for antiviral treatment, and explored the changes in disease burden and cost-effectiveness following increasing the coverage rate and reducing treatment thresholds in order to achieve the global strategic goal of eliminating hepatitis B as soon as possible as a public health threat.

A global investment framework for the elimination of hepatitis B.

BACKGROUND & AIMS: More than 292 million people are living with hepatitis B worldwide and are at risk of death from cirrhosis and liver cancer. The World Health Organization (WHO) has set global targets for the elimination of viral hepatitis as a public health threat by 2030. However, current levels of global investment in viral hepatitis elimination programmes are insufficient to achieve these goals. METHODS: To catalyse political commitment and to encourage domestic and international financing, we used published modelling data and key stakeholder interviews to develop an investment framework to demonstrate the return on investment for viral hepatitis elimination. RESULTS: The framework utilises a public health approach to identify evidence-based national activities that reduce viral hepatitis-related morbidity and mortality, as well as international activities and critical enablers that allow countries to achieve maximum impact on health outcomes from their investments - in the context of the WHO's 2030 viral elimination targets. CONCLUSION: Focusing on hepatitis B, this health policy paper employs the investment framework to estimate the substantial economic benefits of investing in the elimination of hepatitis B and demonstrates how such investments could be cost saving by 2030. LAY SUMMARY: Hepatitis B infection is a major cause of death from liver disease and liver cancer globally. To reduce deaths from hepatitis B infection, we need more people to be tested and treated for hepatitis B. In this paper, we outline a framework of activities to reduce hepatitis B-related deaths and discuss ways in which governments could pay for them.

Economic and Health Care Burdens of Hepatitis Delta: A Study of Commercially Insured Adults in the United States.

BACKGROUND AND AIMS: The paucity of data regarding the extent of hepatitis delta virus (HDV) associated health care burden in the United States is an important obstacle to assessing the cost-effectiveness of potential intervention strategies. In this study, we characterized the health care use and cost burdens of HDV in the United States using real-world claims data. APPROACH AND RESULTS: We conducted a case-control study using the Truven Health MarketScan Commercial Claims databases from 2011-2014. A total of 2,727 HDV cases were matched 1:1 by sociodemographic characteristics and comorbidities to chronic hepatitis B virus (HBV) controls using propensity scores. The HDV group had significantly higher prevalence of substance abuse, sexually transmitted diseases, decompensated cirrhosis, cirrhosis, and hepatitis C virus compared to patients with chronic HBV. First HDV diagnosis was associated with significant increases in the total number of health care claims (25.61 vs. 28.99; P < 0.0001) and total annual health care costs ($19,476 vs. $23,605; P < 0.0001) compared with pre-HDV baseline. The case-control analysis similarly indicated higher total claims (28.99 vs. 25.19; P < 0.0001) and health care costs ($23,605 vs. $18,228; P < 0.0001) in HDV compared with HBV alone. Compared with HBV controls, HDV cases had an adjusted incident rate ratio of 1.16 (95% confidence interval: 1.10, 1.22) times the total number of annual claims and an adjusted incident rate ratio 1.32 (95% confidence interval 1.17, 1.48) times the total annual health care cost. CONCLUSIONS: HDV is associated with higher health care use and cost burden than HBV alone, underscoring the need for improved screening and treatment.

Clinical factors leading to a change in management in chronic hepatitis B patients managed in a tertiary setting.

BACKGROUND: Newer antiviral agents for chronic hepatitis B (CHB) are highly effective, with minimal risks of complications and development of resistance. AIM: To identify the proportion of patients with CHB on treatment who will not require alteration of management and the clinical factors of those who will require closer monitoring. METHODS: Patients with CHB who were on entecavir and/or tenofovir between January 2011 and December 2016 were retrospectively studied. According to the initial treatment plan provided by the managing physician, any deviation in the interval of follow up, choice of investigations and alteration of medical therapy were considered a change in CHB management. We also evaluated the predictability of these changes, factors associated with higher frequency of change and the additional cost of managing stable patients with CHB in a tertiary setting. RESULTS: Of the patients, 75.7% (n = 87/115) did not have a change in CHB management; 85.6% of the changes in management were predictable based on liver function tests, hepatitis B virus DNA polymerase chain reaction levels and liver ultrasound. Interpreter use (OR (95% CI) = 2.41 (1.01-5.76)), liver cirrhosis (OR (95% CI) = 4.11 (1.44-11.75)) and immunosuppression (OR (95% CI) = 3.81 (1.2-12.06)) were associated risk factors. Overall, there was an incremental annual cost of AU$60 166 to manage patients who did not require alteration of their CHB management in our institution. CONCLUSION: The majority of stable CHB patients on highly potent antiviral treatment do not require alteration of management. While additional investigations are required, this study highlights the potential for a shared primary care approach in highly selected CHB patients.

Efficacy and cost-effectiveness of antiviral regimens for entecavir-resistant hepatitis B: A systematic review and network meta-analysis.

BACKGROUND: Chronic hepatitis B (CHB) patients who had exposed to lamivudine (LAM) and telbivudine (LdT) had high risk of developing entecavir (ETV)-resistance after long-term treatment. We aimed to conduct a systematic review and a network meta-analysis on the efficacy and cost-effectiveness on antiviral regimens in CHB patients with ETV-resistance. DATA SOURCES: We searched PubMed, EMBASE and Web of Science for studies on nucleos(t)ide analogues (NAs) treatment [including tenofovir disoproxil fumarate (TDF)-based rescue therapies, adefovir (ADV)-based rescue therapies and double-dose ETV therapy] in CHB patients with ETV-resistance. The network meta-analysis was conducted for 1-year complete virological response (CVR) and biological response (BR) rates using GeMTC and ADDIS. A cost-effective analysis was conducted to select an economic and effective treatment regimen based on the 1-year CVR rate. RESULTS: A total of 6 studies were finally included in this analysis. The antiviral efficacy was estimated. On network meta-analysis, the 1-year CVR rate in ETV-TDF [odds ratio (OR)  = 22.30; 95 % confidence interval (CI): 2.78-241.93], LAM-TDF (OR  = 70.67; 95 % CI: 5.16-1307.45) and TDF (OR  = 16.90; 95 % CI: 2.28-186.30) groups were significantly higher than that in the ETV double-dose group; the 1-year CVR rate in the LAM-TDF group (OR  = 14.82; 95 % CI: 1.03-220.31) was significantly higher than that in the LAM/LdT-ADV group. The 1-year BR rate of ETV-TDF (OR = 28.68; 95 % CI: 1.70-1505.08) and TDF (OR = 21.79; 95 % CI: 1.43-1070.09) therapies were significantly higher than that of ETV double-dose therapy. TDF-based therapies had the highest possibility to achieve the CVR and BR at 1 year, in which LAM-TDF combined therapy was the most effective regimen. The ratio of cost/effectiveness for 1-year treatment was 8 526, 17 649, 20 651 Yuan in the TDF group, TDF-ETV group, and ETV-ADV group, respectively. CONCLUSIONS: TDF-based combined therapies such as ETV-TDF and LAM-TDF therapies were the first-line treatment if financial condition is allowed.

Healthcare resource utilization and costs by disease severity in an insured national sample of US patients with chronic hepatitis B.

BACKGROUND & AIMS: Chronic hepatitis B (CHB) affects over 2 million people in the US, with little reported on healthcare utilization and cost. We aimed to quantify annual CHB utilization and costs by disease severity and payer type. METHODS: Using Commercial, Medicare, and Medicaid databases from 2004 to 2015 and ICD9 codes, we retrospectively identified adults with CHB, analyzing all-cause inpatient, outpatient, and pharmaceutical utilization and costs by disease severity. We compared healthcare utilization and costs between patients with CHB, without advanced liver disease, and matched non-CHB controls. All-cause inpatient, outpatient, and pharmaceutical utilization and costs were reported for each year and adjusted to 2015 dollars. RESULTS: Our sample consisted of 33,904 CHB cases and 86,072 non-CHB controls. All-cause inpatient admissions (average stay 6-10 days) were more frequent in advanced liver disease states. Across all payers, patients with decompensated cirrhosis had the highest emergency department utilization (1.6-2.8 annual visits) and highest mean annual costs. The largest all-cause cost components for Commercial and Medicaid were inpatient costs for all advanced liver disease groups (Commercial: 62%, 47%, 68%; Medicaid: 81%, 72%, 74%, respectively), and decompensated cirrhosis and hepatocellular carcinoma groups for Medicare (Medicare 49% and 48%). In addition, patients with compensated liver disease incurred costs 3 times higher than non-CHB controls. CONCLUSION: Patients with CHB, regardless of payer, who experienced decompensated cirrhosis, hepatocellular carcinoma, or a liver transplant incurred the highest annual costs and utilization of healthcare resources, but even patients with CHB and compensated liver disease incurred higher costs than those without CHB. All stakeholders in disease management need to combine efforts to prevent infection and advanced liver disease through improved vaccination rates, earlier diagnosis, and treatment. LAY SUMMARY: Hepatitis B virus can be a progressive disease leading to cirrhosis, hepatocellular carcinoma, liver transplant, and death. These progressive disease states are associated with a higher rate of hospitalizations, emergency room visits, outpatient visits, and costs compared to similar patients without hepatitis B. The most ill patients have the highest costs, but even patients who are less sick experience higher costs than patients without hepatitis B.

Resource Utilization and Outcomes of Medicare Recipients With Chronic Hepatitis B in the United States.

GOALS: To assess the outcomes and resource utilization of chronic hepatitis B (CH-B) among Medicare beneficiaries. BACKGROUND: CH-B is highly prevalent among immigrants from endemic areas. Although incidence of CH-B is stable in the United States, CH-B patients have become Medicare eligible. STUDY: We used the inpatient and outpatient Medicare database (2005 to 2014). Adult patients with CH-B diagnosis were included. One-year mortality and resource utilization were assessed. Independent associations with resource utilization and mortality were determined using multivariate analysis. RESULTS: Study cohort included 18,603 Medicare recipients with CH-B. Between 2005 and 2014, number of Medicare beneficiaries with CH-B increased by 4.4% annually. The proportion of beneficiaries with CH-B who were whites decreased while those who were Asians increased (P<0.05). Furthermore, 7.4% of CH-B Medicare cohort experienced decompensated cirrhosis, 2.9% hepatocellular carcinoma (HCC) and 11.9% 1-year mortality. Although the number of inpatients with CH-B remained stable, the number of outpatient encounters increased. Annual total inpatient charges increased from $66,610 to $94,221 while these charges for outpatient increased from $9257 to $47,863. In multivariate analysis, age [odds ratio (OR), 1.05; 95% confidence interval (CI), 1.04-1.05], male gender [OR, 1.24 (95% CI, 1.12-1.38)], decompensated cirrhosis [OR, 3.02 (95% CI, 2.63-3.48)], HCC [OR, 2.64 (95% CI, 2.10-3.32)], and higher Charlson comorbidity index [OR, 1.24 (95% CI, 1.21-1.27)] were independently associated with increased 1-year mortality. HCC and higher Charlson comorbidity index were also associated with higher inpatient and outpatient charges, and inpatient length of stay (all P<0.001). CONCLUSIONS: CH-B infection has been rising in Medicare population and is responsible for significant mortality and resource utilization.

Bridging the access gap: Medicare ineligibility in people living with chronic hepatitis B.

People living in Australia on temporary student or work visas are excluded from Medicare access and can face barriers to adequate healthcare, even if they are privately insured. This analysis aimed to quantify this issue in relation to people living with chronic hepatitis B, the majority of whom in Australia were born overseas. The data suggest that an estimated 25 000 people living with chronic hepatitis B in Australia are ineligible for Medicare, 10% of the total number affected, with considerable potential impact in access to effective healthcare and prevention of adverse outcomes.

Assessing the clinical and economic impact of increasing treatment uptake in chronic hepatitis B infection using a Markov model.

Treatment uptake in chronic hepatitis B virus (HBV) infection is low in South Australia, and the cost-effectiveness of increasing treatment uptake rates in this population has not been assessed. AIMS AND METHODS: Using a cohort Markov model, cost-effectiveness was assessed for three different treatment uptake scenarios: 2.9% (current level-scenario 1), 10% (scenario 2), and 15% (scenario 3). The initial HBV population included 2550 treatment eligible patients who transitioned between six different health states over a 10-year period. Treatment transition probabilities were based on tenofovir therapy, while those not assigned to treatment followed the natural history transition probabilities. We estimated the incremental cost per quality adjusted life year gained using the prevented number of deaths, hepatocellular carcinoma, and liver transplants. RESULTS: Scenario 3 was associated with the lowest mean cost/person over 10 years (AU$60 133), compared with scenario 2 (AU$61 964) and scenario 1 (AU$64 597). Scenario 3 was also associated with the highest quality adjusted life year gained (8.196) compared with scenario 2 (7.985) and scenario 1 (7.684). Scenario 3 would result in 50% reduction in hepatocellular carcinoma and 30% reduction in HBV-related mortality compared with scenario 1, over a 10-year period. Higher treatment uptake was found to be cost-effective with at least 2 years of treatment at either 10% or 15% of the target population. CONCLUSION: Maximizing the treatment uptake in the existing HBV population from 2.9% to 15% was cost-effective for periods of 2 years or more. This was due to a reduction in the number of expected clinical events.

Cost-Effectiveness and Clinical Impact of Antiviral Strategies of HBeAg-Positive and -Negative Chronic Hepatitis B.

INTRODUCTION: Chronic hepatitis B (CHB) is associated with high burden and healthcare costs. Virologic response achieved with antivirals is associated with progression avoidance. This study aimed to estimate the efficiency and clinical impact of antiviral strategies in CHB patients. MATERIAL AND METHODS: A Markov model estimated lifetime complications and direct costs in both, HBeAg-positive and HBeAg-negative cohorts. Strategy 1 (71% of treated population) and strategy 2 (100%), both based on pegylated interferon (peg-IFN) followed by oral tenofovir or entecavir, were compared to no treatment. Progression was based on HBV-DNA levels. Rescue therapy with oral antivirals was applied for peg-IFN failure. Disease costs (C, 2014) and utilities were obtained from literature. RESULTS: Compared to natural history, strategy 1 increased QALY (3.98 in HBeAg-positive, 2.16 in -negative cohort). With strategy 2, survival was up to 5.60 (HBeAg-positive) and 3.05 QALY (in HBeAg-negative). The model predicted avoidance of 128 and 86 carcinomas in HBeAg-positive and -negative patients with strategy 1, and up to 181 and 121 in HBeAg-positive and -negative for strategy 2. Total cost increased up to C102,841 (strategy 1) and C105,408 (strategy 2) in HBeAg-positive, and C85,858 and C93,754 in HBeAg-negative. A C1,581/QALY gained ratio was estimated versus the natural history for both strategies. In conclusion, increasing antiviral coverage would be efficient, reducing complications.

Annual economic burden of hepatitis B virus-related diseases among hospitalized patients in twelve cities in China.

A nationwide survey of hepatitis B virus (HBV)-associated economic burden has not previously been performed in China. The purpose of this study was to examine the direct, indirect, and intangible costs of HBV-related diseases within the span of one year. A random sample was taken from specialty and general hospitals across 12 cities in six provinces of China. Intangible costs were estimated based on willingness to pay or open-ended answers provided by patients. The results showed that 27 hospitals were enrolled, with a sample population of 4726 patients (77.7% response rate). The average annual costs were $4454.0 (direct), $924.3 (indirect), and $6611.10 (intangible), corresponding to 37.3%, 7.7%, and 55.1% of the total costs, respectively. The direct medical fees were substantially greater than the non-medical fees. Annual indirect costs were divided into outpatient ($112.9) and inpatient ($811.40) loss of income. The intangible costs of chronic HBV were notably higher than either the direct or indirect costs, consistent with the social stigma in China. The comparison amongst individual cities for the average ratio of direct to indirect costs revealed that the sizes of ratios were negatively correlated with the socioeconomic status of the regions. This study suggested that as a whole in China, the HBV-related diseases caused a heavy financial burden which was positively associated with disease severity. Although the intangible costs coincided with a high prevalence of discrimination against CHB patients in Chinese society, our study may serve as future reference for detailed exploration.

Chronic Hepatitis B Is Associated with Higher Inpatient Resource Utilization and Mortality Versus Chronic Hepatitis C.

BACKGROUND: Chronic hepatitis B virus (HBV) and chronic hepatitis C virus (HCV) infections remain one of the leading causes of chronic liver disease and hepatocellular carcinoma. Healthcare initiatives for chronic viral hepatitis to facilitate early diagnosis and linkage to care in an effort to reduce inpatient resource utilization associated with late diagnosis and end-stage liver disease have been partially successful. AIMS: Our objective was to determine the impact of liver-related complications from chronic HBV and HCV infections on inpatient cost of care, length of stay, and mortality. METHODS: Using the Healthcare Cost and Utilization Project, National Inpatient Sample (HCUP-NIS), we studied the impact of chronic HBV and HCV infections on inpatient healthcare system following hospitalizations from 2003 to 2012. RESULTS: Of the 79,185,729 million hospitalizations among adult patients in the USA from 2003 to 2012, 143,896 (0.18 %) hospitalizations were HBV related and 1,073,269 (1.36 %) hospitalizations HCV related. HBV hospitalizations had a higher inpatient mortality (OR 1.34; 95 % CI 1.30, 1.38), median cost of care per hospitalization (+$2100.33; 95 % CI 1982.53, 2217.53), and increased length of hospitalization stay (+0.64 days; 95 % CI 0.60, 0.68; p < 0.01) compared to HCV. CONCLUSIONS: Despite higher per case resource utilization following hospitalization, HBV-infected patients demonstrate a lower inpatient survival in comparison with chronic HCV infection. These disparate observations underscore the need for early diagnosis of chronic HBV infection in at-risk population and prompt linkage to care.

[Update chronic viral hepatitis]. / Update chronische Virushepatitis.

More than 500,000 people in Germany have chronic viral hepatitis. The interferon-based treatments formerly used in hepatitis B have been widely replaced by life-long oral medication with nucleoside or nucleotide analogues. Treatment for chronic hepatitis C has been improved substantially by the development of new and very expensive drug combinations. Up to 90% of patients can now be cured with certainty, and one to two years after successful treatment there is no relevant risk of recurrence. These individuals expect to receive insurance cover under appropriate conditions. Vaccination programmes are very efficient at decreasing the incidence of hepatitis B, but no vaccine against hepatitis C is likely to become available in the next decade.

Cost effectiveness of response-guided therapy with peginterferon in the treatment of chronic hepatitis B.

BACKGROUND & AIMS: The high prevalence of chronic hepatitis B in Asian countries produces a substantial economic burden. Peginterferon has immunomodulatory effects and a finite course for treatment of hepatitis B, but also a high cost and side effects. The recent introduction of a 12-week stopping rule (stopping treatment after 12 weeks) has increased its appeal as a first-line treatment for hepatitis B. We aimed to determine the cost effectiveness of the 12-week stopping rule for peginterferon in hepatitis B e antigen (HBeAg)-positive and HBeAg-negative patients. METHODS: We used Markov modeling, with data from the Hong Kong population, to compare the cost effectiveness of peginterferon therapy with a 12-week stopping rule vs conventional therapy (48 weeks) and with other antiviral agents. RESULTS: For HBeAg-positive patients, stopping peginterferon therapy after 12 weeks had the lowest cost-effectiveness ratio (CER), of $9501/quality-adjusted life-year (QALY), compared with no treatment, making it the most cost-effective option. Conventional (48-week) peginterferon treatment had a CER of $9664/QALY. For HBeAg-negative patients, entecavir had the lowest CER ($34,310/QALY). Entecavir was more cost effective than either peginterferon strategies (CERs of $37,423/QALY for 12 weeks of peginterferon and $38,474/QALY for 48 weeks of treatment). CONCLUSIONS: The 12-week stopping rule increases the cost effectiveness of peginterferon therapy, and is the most cost-effective treatment for HBeAg-positive patients. The need for long-term antiviral therapy for HBeAg-negative patients makes entecavir the most cost-effective strategy.

Population health impact and cost-effectiveness of monitoring inactive chronic hepatitis B and treating eligible patients in Shanghai, China.

UNLABELLED: Inactive chronic hepatitis B (CHB) carriers make up the largest group of hepatitis B virus-infected patients, and China bears the largest total CHB burden of any country. We therefore assessed the population health impact and cost-effectiveness of a strategy of lifelong monitoring for inactive CHB and treatment of eligible patients in Shanghai, China. We used a computer simulation model to project health outcomes among a population cohort of CHB based on age-specific prevalence of hepatitis B surface antigen (HBsAg), hepatitis B e antigen (HBeAg), and cirrhosis. Using a Markov model we simulated patients' progression through a discrete series of health states, and compared current practice to a monitor and treat (M&T) strategy. We measured lifetime costs and quality-adjusted life years (QALYs) (both discounted at 3% per year), incremental cost-effectiveness ratios (ICERs), and clinical outcomes such as development of hepatocellular carcinoma (HCC). We estimated that there are 1.5 million CHB-infected persons in Shanghai. The M&T strategy costs US$20,730 per patient and yields a discounted QALY of 15.45, which represents incremental costs and health benefits of US$275 and 0.10 QALYs compared to current practice, and an ICER of US$2,996 per QALY gained. In the base case, we estimated that the M&T strategy will reduce HCC and CHB-related mortality by only around 1%. If variables such as adherence to monitoring and treatment could be substantially improved the M&T strategy could reduce HCC by 70% and CHB-related mortality by 83%. CONCLUSION: Lifelong monitoring of inactive CHB carriers is cost-effective in Shanghai according to typical benchmarks for value for money, but achieving substantial population-level health gains depends on identifying more CHB-infected cases in the population, and increasing rates of treatment, monitoring, and treatment adherence.

Cost-Effectiveness Analysis of Alternative Antiviral Strategies for the Treatment of HBeAg-Positive and HBeAg-Negative Chronic Hepatitis B in the United Kingdom.

BACKGROUND: Seven drugs are licensed for the treatment of chronic hepatitis B (CHB) in the United Kingdom. Which initial treatment, secondary therapy, and whether antivirals should be given alone or in combination are questions of considerable uncertainty. OBJECTIVE: The aim of this model was to undertake a comprehensive economic evaluation of all antiviral treatments for CHB to recommend the most cost-effective therapeutic sequence. METHODS: We developed a probabilistic Markov model to compare the cost-effectiveness of all clinically relevant antiviral treatment sequences for nucleos(t)ide-naive adults with hepatitis B e-antigen (HBeAg)-positive or HBeAg-negative CHB. Relative rates of HBeAg seroconversion and viral suppression were obtained from a network meta-analysis. Data on mortality, antiviral drug resistance, durability of response, adverse events, and costs were obtained from published literature. Results are reported in terms of lifetime costs, quality-adjusted life-years (QALYs), and expected net benefit. RESULTS: In the base-case analysis, pegylated interferon alpha-2a (peg-IFN α-2a) followed by tenofovir disoproxil fumarate was most effective and cost-effective in HBeAg-positive patients, with a cost of £7488 per QALY gained compared with no treatment. In HBeAg-negative patients, peg-IFN α-2a followed by entecavir was most effective and cost-effective, with a cost of £6981 per QALY gained. The model was robust to a wide range of sensitivity analyses. CONCLUSIONS: Peg-IFN α-2a followed by tenofovir disoproxil fumarate or entecavir is the most effective antiviral treatment strategy for people with both variants of CHB. At a cost of less than £10,000 per QALY gained, these sequences are considered cost-effective in England and Wales. The results of this analysis were used to inform 2013 National Institute for Health and Care Excellence guideline recommendations.

Medical and economic burden of chronic hepatitis B patients at Queen Savang Vadhana Memorial Hospital.

OBJECTIVE: To study and to compare the medical and economic burden among chronic hepatitis B (CHB) patients. MATERIAL AND METHOD: A prospective observational study was conducted among 129 adult CHB patients. The medical burden was assessed by using the EuroQol-5D (EQ-5D) and the Chronic Liver Disease Questionnaire (CLDQ) at initial day, the six and 12-month follow-up. The economic burden was assessed in term of total cost per case per year RESULTS: At one-year follow-up, the mean age of 129 patients was 41.6 (SD = 11.8) years. For medical burden at over time, CHB with antiviral drugs (ARV) for hepatitis B infection had a significant decreased in percentage of anxiety, and increased the mean (SD) CLDQ score. The mean total costs per case per year of CHB without ARV (52 cases), CHB with antiviral drugs (50 cases), and CHB with cirrhosis/hepatocellular carcinoma (HCC) with ARV (27 cases) were significantly different (p < 0.001) with USD 615.9 (SD = 688.0), 1,777.4 (SD = 1,220.4), and 2,651.3 (SD = 3,885.0), respectively. CONCLUSION: CHB causes a great economic burden in Thailand Early antiviral drugs treatment prevents complication in CHB patients.

Antenatal lamivudine to reduce perinatal hepatitis B transmission: a cost-effectiveness analysis.

OBJECTIVES: This study aimed to determine whether administration of lamivudine to pregnant women with chronic hepatitis B in the third trimester is a cost-effective strategy in preventing perinatal transmission. STUDY DESIGN: We developed a decision analysis model to compare the cost-effectiveness of 2 management strategies for chronic hepatitis B in pregnancy: (1) expectant management or (2) lamivudine administration in the third trimester. We assumed that lamivudine reduced perinatal transmission by 62%. RESULTS: Our Markov model demonstrated that lamivudine administration is the dominant strategy. For every 1000 infected pregnant women treated with lamivudine, $337,000 is saved and 314 quality-adjusted life-years are gained. For every 1000 pregnancies with maternal hepatitis B, lamivudine prevents 21 cases of hepatocellular carcinoma and 5 liver transplants in the offspring. The model remained robust in sensitivity analysis. CONCLUSION: Antenatal lamivudine administration to pregnant patients with hepatitis B is cost-effective, and frequently cost-saving, under a wide range of circumstances.
