RESUMO
INTRODUCTION: Invasive meningococcal disease (IMD) caused by Neisseria meningitidis is a rapidly progressing, rare disease that often presents as meningitis or sepsis. It mostly affects infants and adolescents, with high fatality rates or long-term sequelae. In the Netherlands, serogroup B (MenB) is most prevalent. We aimed to estimate the economic burden of MenB-related IMD between 2015 and 2019, including direct and indirect medical costs from short- and long-term sequelae, from a societal perspective. METHODS: IMD incidence was based on laboratory-based case numbers from the Netherlands Reference Laboratory for Bacterial Meningitis (Amsterdam UMC, Amsterdam, the Netherlands); there were 74 MenB cases on average per year in the study period 2015-2019. Case-fatality rate (3.8%) and percentage of patients discharged with sequelae (46%) were derived from literature. Direct costs included treatment costs of the acute phase, long-term sequelae, and public health response. Indirect costs were calculated using the human capital (HCA) and friction costs (FCA) approaches, in which productivity losses were estimated for patients and parents during the acute and sequelae phases. Costs were discounted by 4% yearly. RESULTS: Estimated costs due to MenB IMD in an annual cohort were 3,094,199 with FCA and 9,480,764 with HCA. Direct costs amounted to 2,974,996, of which 75.2% were related to sequelae. Indirect costs related to sequelae were 52,532 with FCA and 5,220,398 with HCA. CONCLUSION: Our analysis reflects the high economic burden of MenB-related IMD in the Netherlands. Sequelae costs represent a high proportion of the total costs. Societal costs were dependent on the applied approach (FCA or HCA).
RESUMO
Introduction: Immunocompromised patients (ICP) have an increased risk for infectious diseases. Vaccines could help reduce this risk. However, ICP do not always receive or are reimbursed for the specific vaccinations on which they are dependent in the Netherlands. This research aims to gain insights into the current challenges in the vaccination process of ICP in the Netherlands. Moreover, it aims to explore potential solutions for these challenges and the ideal vaccination process. Methods: Twelve semi-structured interviews with relevant stakeholders were conducted. Partly based on the challenges found by the Council for Health and Society (RVS) and the Dutch National Health Care Institute (ZIN) an interview guide was developed. Results: Several newly emerged challenges were identified: fair reimbursement for the efforts of stakeholders; circular reasoning of vaccine reimbursement and guidelines; suboptimal translation from guidelines to practice and no smooth-running infrastructure. Most challenges corresponded with those stated by the RVS and ZIN. Affordability and knowledge deficit in healthcare providers and patients were the most important challenges. Rarely the same solutions were mentioned, and no ideal vaccination process emerged. Conclusions: The various challenges in the vaccination process of ICP in the Netherlands implies the difficulty to solve the problem. It is recommended to focus on solving the most important challenges. A potential solution is to adjust the GVS registration process to make it easier for the pharmaceutical industry to apply for reimbursement towards various high-risk groups. Additionally, vaccination should have a more prominent role in the education of healthcare providers. Furthermore, stakeholders need to cooperate more to solve the reimbursement and guidelines issue.
RESUMO
In the Netherlands, the Health Council has advised that the human papillomavirus (HPV) vaccination should be offered to both boys and girls. Additionally, boys and men up to the age of 26 years should be included in a catch-up program. In this study, we examine the cost-effectiveness of this HPV catch-up program. We used a static Markov model to estimate the amount of cancers prevented and the incremental cost-effectiveness ratio (ICER) for different scenarios. Vaccinating men from 12 until the age of 26 years would result in an average of 48 cancer cases prevented in every cohort (an estimated total of 720 cases), with an average ICER of 32,256. We found that the catch-up vaccination program results in a relevant number prevented cases against an acceptable cost-effectiveness ratio. Policymakers should take these findings into account when evaluating a gender-neutral HPV vaccination program in the Netherlands.
RESUMO
BACKGROUND: Vaccinating girls against human papillomavirus (HPV) infection is a highly effective and cost-effective intervention to provide protection against HPV-induced cancers. Since vaccination coverage rates among girls is modest in the Netherlands, additional strategies should be implemented to improve the protection against HPV-related cancer. Here we assessed the benefits and cost-effectiveness of gender-neutral vaccination. METHODS: We designed a static Markov model with a lifelong time horizon to simulate a cohort of 100,000 12-year-old Dutch boys. The model compares health and economic effects of HPV vaccination taking the current female vaccination coverage into consideration. HPV prevalence in boys was corrected for the predicted herd effects of the female programme in 2017. We extracted transition probabilities from peer-reviewed literature and previously constructed models. The robustness of the model was tested with multiple sensitivity analyses. RESULTS: Vaccinating 30% of 100,000 12-year-old boys prevents 18, 13 and 25 cases of anal, penile, and oropharyngeal cancers in men, respectively. A total of 205 quality-adjusted life-years (QALYs) are saved by preventing cancer-related morbidity and mortality. Assuming a vaccine price of 50 per dose, the incremental cost-effectiveness ratio (ICER) is 17,907 per QALY. In addition, due to vaccine-induced herd effects, we estimated that 110 cases of cancer in females would be additionally prevented and 246 QALYs would be gained in the female cohort, bringing the total to 166 cancers prevented and 451 QALYs gained. Taking these additional benefits of boys' vaccination into account, the overall ICER was estimated at 7310 per QALY gained. The model outcomes are most sensitive to variation in vaccine price, herd immunity from females and vaccine efficacy. CONCLUSIONS: Vaccination of boys, additional to girls, will prevent a relevant number of cancers in both boys and girls. Based on the current Dutch situation vaccination of HPV in boys is likely cost-effective. GSK Study identifier: HO-18-19169.
