Fluorescence detection of pituitary neuroendocrine tumour during endoscopic transsphenoidal surgery using bevacizumab-800CW: a non-randomised, non-blinded, single centre feasibility and dose finding trial [DEPARTURE trial].

PURPOSE: Achieving endocrine remission by gross total resection is challenging in pituitary neuroendocrine tumours (PitNETs) with cavernous sinus invasion. This study aims to assess the safety, feasibility, and optimal dose for intraoperative fluorescence imaging as an added instrument to discriminate PitNET from surrounding tissue using bevacizumab-800CW, targeting vascular endothelial growth factor A (VEGF-A). METHODS: In part I, dose-escalation (0-4∙5-10-25 mg) was performed in 4 groups of 3 patients with PitNETs Knosp grade 3-4. In part II, after interim analysis, the 10 mg and 25 mg groups were expanded to a total of 6 patients. Quantitative fluoroscence molecular endoscopy consisted of wide field fluorescence molecular endoscopy and multi-diameter single fiber reflectance / single fiber fluorescence spectroscopy. Mean fluorescence intensity (MFI) of the fresh surgical specimen was calculated and VEGF-staining was performed. RESULTS: Eighteen patients were included. All doses were well tolerated. Three serious adverse events were registered, but none were tracer-related. Part I showed an adequate in-vivo tumour-to-background ratio for both 10 mg (TBR 2∙00 [1∙86, 2∙19]) and 25 mg (TBR 2∙10, [1∙86, 2∙58]). Part II revealed a substantially higher MFI in the 25 mg group. With both 10 mg and 25 mg a statistically significant difference between tumour and surrounding tissue was detected (p < 0∙0001). All surgical specimens had VEGF-A expression. CONCLUSION: This study demonstrates the safety and feasibility of quantitative fluorescence molecular endoscopy during PitNET surgery. Both 10 mg and 25 mg bevacizumab-800CW result in clear differentiation in-vivo, with improved contrast ex-vivo (MFI) in the 25 mg group.

Health-economic evaluation of meniscus tear treatments: a systematic review.

PURPOSE: To evaluate the overall evidence of published health-economic evaluation studies on meniscus tear treatment. METHODS: Our systematic review focuses on health-economic evaluation studies of meniscus tear treatment interventions found in PubMed and Embase databases. A qualitative, descriptive approach was used to analyze the studies' results and systematically report them following PRISMA guidelines. The health-economic evaluation method for each included study was categorized following one of the four approaches: partial economic evaluation (PEE), cost-effectiveness analysis (CEA), cost-benefit analysis (CBA), or cost-utility analysis (CUA). The quality of each included study was assessed using the Consensus on Health Economic Criteria (CHEC) list. Comparisons of input variables and outcomes were made, if applicable. RESULTS: Sixteen studies were included; of these, six studies performed PEE, seven studies CUA, two studies CEA, and one study combined CBA, CUA, and CEA. The following economic comparisons were analyzed and showed the respective comparative outcomes: (1) meniscus repair was more cost-effective than arthroscopic partial meniscectomy (meniscectomy) for reparable meniscus tear; (2) non-operative treatment or physical therapy was less costly than meniscectomy for degenerative meniscus tear; (3) physical therapy with delayed meniscectomy was more cost-effective than early meniscectomy for meniscus tear with knee osteoarthritis; (4) meniscectomy without physical therapy was less costly than meniscectomy with physical therapy; (5) meniscectomy was more cost-effective than either meniscus allograft transplantation or meniscus scaffold procedure; (6) the conventional arthroscopic instrument cost was lower than laser-assisted arthroscopy in meniscectomy procedures. CONCLUSION: Results from this review suggest that meniscus repair is the most cost-effective intervention for reparable meniscus tears. Physical therapy followed by delayed meniscectomy is the most cost-effective intervention for degenerative meniscus tears. Meniscus scaffold should be avoided, especially when implemented on a large scale. LEVEL OF EVIDENCE: Systematic review of level IV studies.

"Cost-effectiveness of ACL treatment is dependent on age and activity level: a systematic review".

PURPOSE: To systematically review the literature on health-economic evaluations of anterior cruciate ligament (ACL) injury between reconstruction surgery (ACLR) and non-operative treatment (NO) and suggest the most cost-effective strategy between the two. METHODS: All economic studies related to ACLR versus NO post-ACL injury, either trial based or model based, published until April 2022, were identified using PubMed and Embase. The methodology of the health-economic analysis for each included study was categorized according to the four approaches: cost-minimization analysis (CMA), cost-effectiveness analysis (CEA), cost-benefit analysis (CBA), and cost-utility analysis (CUA). The quality of each included study was assessed using the Consensus on Health Economic Criteria (CHEC) list. RESULTS: Of the seven included studies, two compared the strategies of early ACLR and NO alone, and five compared early ACLR and NO with optional delayed ACLR. All studies performed a CUA, and one study performed a CBA additionally. The CHEC scores of the included studies can be considered good, ranging from 15 to 18 from a maximum of 19. Applying the common standard threshold of $50,000 per QALY, six studies in young people with high-activity levels or athletes showed that early ACLR would be preferred over either NO alone or delayed ACLR. Of six studies, two even showed early ACLR to be the dominant strategy over either NO alone or delayed ACLR, with per-patient cost savings of $5,164 and $1,803 and incremental per-patient QALY gains of 0.18 and 0.28, respectively. The one study in the middle-aged people with a moderate activity level showed that early ACLR was not more cost-effective than delayed ACLR, with ICER $101,939/QALY using the societal perspective and ICER $63,188/QALY using the healthcare system perspective. CONCLUSION: Early ACLR is likely the more cost-effective strategy for ACL injury cases in athletes and young populations with high-activity levels. On the other hand, non-operative treatment with optional delayed ACLR may be the more cost-effective strategy in the middle age population with moderate activity levels. LEVEL OF EVIDENCE: Systematic review of level III studies.

Exploratory Analysis of the Economically Justifiable Price of a Hypothetical RSV Vaccine for Older Adults in the Netherlands and the United Kingdom.

BACKGROUND: In older adults, the burden of respiratory syncytial virus (RSV) resembles that of influenza and may even be considered worse due to the lack of preventive interventions. This study was performed to identify the available literature on RSV infection in older adults, and to provide updated exploratory results of the cost-effectiveness of a hypothetical RSV vaccine in the Netherlands and the United Kingdom. METHODS: A literature search was performed in Medline and EMBASE on 11 November 2019, which served as input for a static decision-tree model that was used to estimate the EJP, for an RSV vaccine applying different willingness-to-pay (WTP) thresholds. WTP thresholds applied were €20 000 and €50 000 per quality-adjusted life-year for the Netherlands, and £20 000 and £30 000 per quality-adjusted life-year for the United Kingdom. Analyses were-in line with country-specific guidelines-conducted from a societal perspective for the Netherlands and a third-party payer perspective for the United Kingdom. The robustness of the cost-effectiveness results was tested in sensitivity analysis. RESULTS: After screening the literature, 3 studies for the Netherlands and 6 for the United Kingdom remained to populate the country-specific models. In the base case analysis for the Netherlands (mean RSV incidence, 3.32%), justifiable vaccine prices of €16.38 and €50.03 were found, based on applying the lower and higher WTP thresholds, respectively. Similarly, for the United Kingdom (mean incidence, 7.13%), vaccine prices of £72.29 and £109.74 were found, respectively. CONCLUSION: RSV vaccination may well be cost-effective in both the Netherlands and the United Kingdom, depending on the exact RSV incidence, vaccine effectiveness and price. However, sensitivity analysis showed that the results were robust based on varying the different parameter estimates and assumptions. With RSV vaccines reaching the final stages of development, a strong need exists for cost-effectiveness studies to understand economically justifiable pricing of the vaccine.

Revisiting consciousness: Distinguishing between states of conscious focused attention and mind wandering with EEG.

Fluctuating between external conscious processing and mind wandering is inherent to the human condition. Past research showed that in tasks requiring sustained attention, mind wandering episodes in which attention is directed internally constrain conscious processing of external stimuli. Conversely, conscious processing of internal stimuli is enhanced during mind wandering. To investigate this, we developed and administered a visuomotor tracking task in which participants were instructed to track the path of a stimulus on a screen with a mouse while responding to rare targets. Prior to reports of mind wandering we found the following: The P3 event-related potential component for targets, indicative of conscious stimulus processing, was attenuated at electrodes Cz and Pz. Moreover, alpha power, indicative of internal mental states, increased globally. Theta power increased along the centroparietal area, and beta decreased along right frontal and right centroparietal areas. Interestingly, trait mind wandering was positively correlated with delta power and gamma power, but negatively correlated with the theta-beta ratio. These results demonstrate that mind wandering is characterized by distinct neural signatures at both a state and trait level.

Cost-minimisation analysis of a treat-and-extend regimen with anti-VEGFs in patients with neovascular age-related macular degeneration.

PURPOSE: Although intraocular anti-vascular endothelial growth factors (anti-VEGFs) are effective as treatment of neovascular age-related macular degeneration (nAMD), the (economic) burden on the healthcare system is considerable. A treat-and-extend (T&E) regimen is associated with a lower number of injections without compromising the effectiveness and can therefore help optimise nAMD treatment. This study investigates the per-patient costs associated with nAMD treatment, when using aflibercept, bevacizumab, or ranibizumab with a T&E regimen. METHODS: In this cost-minimisation model, the per-patient costs in the Netherlands were modelled using a healthcare payers' perspective over a 3-year time horizon with the assumption that efficacy of treatments is similar. Additionally, the break-even price of the different anti-VEGFs was calculated relative to the cheapest option and injection frequency. RESULTS: The injection frequency varied from 14.2 for aflibercept to 27.4 for bevacizumab in 3 years. Nonetheless, bevacizumab remains the cheapest treatment option (€14,215), followed by aflibercept (€18,202) and ranibizumab (€31,048). The medication covers the majority of the per-patient costs for aflibercept and ranibizumab, while administration covers the majority of the per-patient costs for bevacizumab. The break-even prices of aflibercept and ranibizumab are respectively €507 and €60.58 per injection. Brolucizumab was included in the scenario analysis and was more expensive than aflibercept (€20,446). Brolucizumab should reduce to 13.8 injections over 3 years to be as costly as aflibercept. CONCLUSION: Bevacizumab is the cheapest anti-VEGF treatment. The list prices of all anti-VEGFs should reduce to be as costly as bevacizumab. Aflibercept is the second-choice treatment and so far brolucizumab is not.

HIV care cost in England: a cross-sectional analysis of antiretroviral treatment and the impact of generic introduction.

OBJECTIVES: Reliable and timely HIV care cost estimates are important for policy option appraisals of HIV treatment and prevention strategies. As HIV clinical management and outcomes have changed, we aimed to update profiles of antiretroviral (ARV) usage pattern, patent/market exclusivity details and management costs in adults (≥ 18 years old) accessing HIV specialist care in England. METHODS: The data reported quarterly to the HIV and AIDS Reporting System in England was used to identify ARV usage pattern, and were combined with British National Formulary (BNF) prices, non-ARV care costs and patent/market exclusivity information to generate average survival-adjusted lifetime care costs. The cumulative budget impact from 2018 to the year in which all current ARVs were expected to lose market exclusivity was calculated for a hypothetical 85 000 (± 5000) person cohort, which provided an illustration of potential financial savings afforded by bioequivalent generic switches. Price scenarios explored BNF70 (September 2015) prices and generics at 10/20/30/50% of proprietary prices. The analyses took National Health Service (NHS) England's perspective (as the payer), and results are presented in 2016/2017 British pounds. RESULTS: By 2033, most currently available ARVs would lose market exclusivity; that is, generics could be available. Average per person lifetime HIV cost was ~£200 000 (3.5% annual discount) or ~£400 000 (undiscounted), reducing to ~£70 000 (3.5% annual discount; ~£120 000 undiscounted) with the use of generics (assuming that generics cost 10% of proprietary prices). The cumulative budget to cover 85 000 (± 5000) persons for 16 years (2018-2033) was £10.5 (± 0.6) billion, reducing to £3.6 (± 0.2) billion with the use of generics. CONCLUSIONS: HIV management costs are high but financial efficiency could be improved by optimizing generic use for treatment and prevention to mitigate the high cost of lifelong HIV treatment. Earlier implementation of generics as they become available offers the potential to maximize the scale of the financial savings.

The C-terminus of the oncoprotein TGAT is necessary for plasma membrane association and efficient RhoA-mediated signaling.

BACKGROUND: Rho guanine exchange factors (RhoGEFs) control cellular processes such as migration, adhesion and proliferation. Alternative splicing of the RhoGEF Trio produces TGAT. The RhoGEF TGAT is an oncoprotein with constitutive RhoGEF activity. We investigated whether the subcellular location of TGAT is critical for its RhoGEF activity. METHODS: Since plasma membrane associated RhoGEFs are particularly effective at activating RhoA, plasma membrane localization of TGAT was examined. To this end, we developed a highly sensitive image analysis method to quantitatively measure plasma membrane association. The method requires a cytoplasmic marker and a plasma membrane marker, which are co-imaged with the tagged protein of interest. Linear unmixing is performed to determine the plasma membrane and cytoplasmic component in the fluorescence signal of protein of interest. RESULTS: The analysis revealed that wild-type TGAT is partially co-localized with the plasma membrane. Strikingly, cysteine TGAT-mutants lacking one or more putative palmitoylation sites in the C-tail, still showed membrane association. In contrast, a truncated variant, lacking the last 15 amino acids, TGATΔ15, lost membrane association. We show that membrane localization of TGAT was responsible for high RhoGEF activity by using a RhoA FRET-sensor and by determining F-actin levels. Mutants of TGAT that still maintained membrane association showed similar activity as wild-type TGAT. In contrast, the activity was abrogated for the cytoplasmic TGATΔ15 variant. Synthetic recruitment of TGATΔ15 to membranes confirmed that TGAT effectively activates RhoA at the plasma membrane. CONCLUSION: Together, these results show that membrane association of TGAT is critical for its activity.

Burden of early, advanced and metastatic breast cancer in The Netherlands.

BACKGROUND: The aim of this study was to estimate the total economic and health related burden of breast cancer in the Netherlands. METHODS: Data on incidence, prevalence, mortality and survival were extracted from the Dutch National Cancer Registry and were used to calculate the economic and health related burden of breast cancer for overall, DCIS (stage 0), early- (stage I), locally advanced- (stage II-III) and metastatic- (stage IV) breast cancer by age groups and by year (if applicable). RESULTS: The overall incidence of breast cancer increased from 103.4 up to 153.2 per 100,000 women between 1990 and 2014. The increase was driven by DCIS and early breast cancer as the incidence of locally advanced and metastatic breast cancer remained stable. Between 1990 and 2014, ten-year overall survival rates increased from 87% to 93% for early breast cancer, 41% to 62% for locally advanced- and from 6% to 9% for metastatic disease. Annually, breast cancer in the Netherlands is responsible for approximately 3100 deaths, 26,000 life years lost, 65,000 Disability Adjusted Life Years (DALYs) and an economic burden of €1.27 billion. CONCLUSIONS: This study provides a comprehensive assessment of the burden of breast cancer and subsequent trends over time in the Netherlands.

Quantifying the impact of mass vaccination programmes on notified cases in the Netherlands.

Vaccination programmes are considered a main contributor to the decline of infectious diseases over the 20th century. In recent years, the national vaccination coverage in the Netherlands has been declining, highlighting the need for continuous monitoring and evaluation of vaccination programmes. Our aim was to quantify the impact of long-standing vaccination programmes on notified cases in the Netherlands. We collected and digitised previously unavailable monthly case notifications of diphtheria, poliomyelitis, mumps and rubella in the Netherlands over the period 1919-2015. Poisson regression models accounting for seasonality, multi-year cycles, secular trends and auto-correlation were fit to pre-vaccination periods. Cases averted were calculated as the difference between observed and expected cases based on model projections. In the first 13 years of mass vaccinations, case notifications declined rapidly with 82.4% (95% credible interval (CI): 74.9-87.6) of notified cases of diphtheria averted, 92.9% (95% CI 85.0-97.2) cases of poliomyelitis, and 79.1% (95% CI 67.1-87.4) cases of mumps. Vaccination of 11-year-old girls against rubella averted 49.9% (95% CI 9.3-73.5) of cases, while universal vaccination averted 68.1% (95% CI 19.4-87.3) of cases. These findings show that vaccination programmes have contributed substantially to the reduction of infectious diseases in the Netherlands.

Application of multiblock modelling to identify key drivers for antimicrobial use in pig production in four European countries.

Antimicrobial use in pig farming is influenced by a range of risk factors, including herd characteristics, biosecurity level, farm performance, occurrence of clinical signs and vaccination scheme, as well as farmers' attitudes and habits towards antimicrobial use. So far, the effect of these risk factors has been explored separately. Using an innovative method called multiblock partial least-squares regression, this study aimed to investigate, in a sample of 207 farrow-to-finish farms from Belgium, France, Germany and Sweden, the relative importance of the six above mentioned categories or 'blocks' of risk factors for antimicrobial use in pig production. Four country separate models were developed; they showed that all six blocks provided useful contribution to explaining antimicrobial use in at least one country. The occurrence of clinical signs, especially of respiratory and nervous diseases in fatteners, was one of the largest contributing blocks in all four countries, whereas the effect of the other blocks differed between countries. In terms of risk management, it suggests that a holistic and country-specific mitigation strategy is likely to be more effective. However, further research is needed to validate our findings in larger and more representative samples, as well as in other countries.

Health-related quality of life in HIV/AIDS patients on antiretroviral therapy at a tertiary care facility in Zimbabwe.

Health-related quality of life (HRQoL) is a broad concept reflecting a patient's general subjective perception of the effect of an illness or intervention on physical, psychological and social aspects of their daily life. HRQoL among patients infected with HIV has become an important indicator of impact of disease and treatment outcomes. A cross-sectional survey was carried out at Chitungwiza Central Hospital, Zimbabwe, to assess HRQoL in patients with HIV/AIDS receiving antiretroviral therapy (ART), using two validated instruments. The HIV/AIDS-targeted quality of life (HAT-QoL) and EuroQoL Five-dimensions-Three-level (EQ-5D-3L) instruments were used to assess HRQoL. Internal consistency reliability and convergent validity of the two instruments were also evaluated. For construct validity, the relationships between HRQoL scores and socio-economic and HIV/AIDS-related characteristics were explored. The median scores for the HAT-QoL dimensions ranged from 33.3 (financial worries) to 100 (HIV mastery). A considerably low HAT-QoL dimension score of 50.0 was observed for sexual function. There were ceiling effects for all HAT-QoL dimension scores except for financial worries and disclosure worries. Floor effects were observed for financial worries and sexual function. The median of the EQ-5D-3L index and visual analogue scale (VAS) was 0.81 and 79.0, respectively. There were no floor or ceiling effects for both the EQ-5D-3L index and VAS. The overall scale Cronbach's alpha was 0.83 for HAT-Qol and 0.67 for EQ-5D-3L. HAT-QoL demonstrated good convergent validity with EQ-5D index (0.58) and VAS (0.40). A higher level of HRQoL was positively and significantly related to income, education and employment. The patients' self-reported HRQoL was generally satisfactory in all the HAT-QoL dimensions as well as the two components on the EQ-5D-3L instrument. The two instruments demonstrated good measurement properties in HIV/AIDS patients receiving ART and have potential for use, alongside biomarkers, in monitoring outcomes of interventions.

Costs and benefits of individuals conceived after IVF: a net tax evaluation in The Netherlands.

This study evaluated the lifetime future net tax revenues from individuals conceived after IVF relative to those naturally conceived. A model based on the method of generational accounting was developed to evaluate investments in IVF. Calculations were based on average investments paid and received from the government by an individual. All costs were discounted to their net present values and adjusted for survival. The lifetime net present value of IVF-conceived individuals was -€81,374 (the minus sign reflecting negative net present value). The lifetime net present value of IVF-conceived men and women were -€47,091 and -€123,177, respectively. The lifetime net present value of naturally conceived individuals was -€70,392; respective amounts for men and women were -€36,109 and -€112,195. The model was most sensitive to changes in the growth of healthcare costs, economic growth and the discount rate. Therefore, it is concluded that, similarly to naturally conceived individuals in the Netherlands, IVF-conceived individuals have negative discounted net tax revenue at the end of life. The analytic framework described here undervalues the incremental value of an additional birth because it only considers the fiscal consequences of life and does not take into consideration broader macroeconomic benefits.

Can Cyprus Afford Luspatercept? A Budget Impact Analysis of the Reimbursement of Luspatercept for the Management of Thalassaemia in Cyprus.

OBJECTIVE: This study aims to estimate the budget impact of luspatercept reimbursement as an adjuvant to the standard management of ß-thalassaemia major in Cyprus, from a societal perspective, and assess the financial feasibility of its inclusion in the ß-thalassaemia armamentarium. METHODS: A 5-year horizon budget impact model was developed to determine the budget impact of reimbursing luspatercept for the management of ß-thalassaemia major in Cyprus. Two treatment discontinuation scenarios were elaborated. In the first scenario, luspatercept is reimbursed complementary to best supportive care, and a dropout rate of 40% is assumed based on published real-world data, while for the second scenario a dropout rate of 25%, is assumed as per the clinical trial data. Input parameters were retrieved from the phase III clinical trial of luspatercept, literature, and expert opinion consensus. One-way sensitivity analyses were conducted for both scenarios. RESULTS: The addition of luspatercept to the standard management of ß-thalassaemia major in Cyprus imparted an incremental budget impact ranging from €21,300,643 to €25,834,368, depending on the drop-out rate scenario assumed. Results were sensitive to the number of eligible patients and dose per patient. CONCLUSION: The potential reimbursement of luspatercept will wield a substantial impact on Cyprus total pharmaceutical expenditure and it is therefore imperative to affix a reimbursement framework that will allow the payer to mitigate uncertainty stemming out of the scarce clinical data and the inherently complex therapeutic landscape of ß-thalassemia management.

The role of Streptococcus pneumoniae in community-acquired pneumonia among adults in Europe: a meta-analysis.

The primary objective of this meta-analysis was to estimate the prevalence of adult community-acquired pneumonia (CAP) caused by Streptococcus pneumoniae in Europe, adjusted for possible independent covariates. Two reviewers conducted a systematic literature search using PubMed on English-language articles that involved human subjects with CAP during the period from January 1990 to November 2011 across European countries. A mixed-effects meta-regression model was developed and populated with 24,410 patients obtained from 77 articles that met the inclusion criteria. The model showed that the observed prevalence of S. pneumoniae in CAP significantly varies between European regions, even after adjusting for explanatory covariates, including patient characteristics, diagnostic tests, antibiotic resistance, and health-care setting. The probability of detecting S. pneumoniae was substantially higher in studies that performed more frequently a diagnostic polymerase chain reaction assay compared to all the other diagnostic tests included. Furthermore, S. pneumoniae was more likely to be confirmed as the cause of a CAP in studies with intensive care unit patients as compared to those with hospital- or community-treated patients. This study provides estimates of the average observed prevalence of S. pneumoniae, which could be used for projecting the health and economic benefits of pneumococcal immunization.

Evaluating interventions to improve somatic health in severe mental illness: a systematic review.

OBJECTIVE: To present a systematic review of the evaluation of randomized interventions directed toward improving somatic health for patients with severe mental illness (SMI). METHOD: A systematic search in PubMed, Embase, Cinahl, and PsycInfo was performed. The scope of the search was prospective studies for patients aged 18-70, published from January 2000 till June 2011. Randomized interventions directed toward improving somatic health for patients with SMI were selected. We excluded studies on elderly, children, and studies performed before 2000. Information on population, type of intervention, follow-up, outcome measures, and on authors' conclusions were drawn from the original articles. RESULTS: Twenty-two original studies were included, presenting four types of interventions: health education (n = 9), exercise (n = 6), smoking cessation (n = 5), and changes in health care organization (n = 2). To evaluate the effect of these studies 93 different outcome measures were used in 16 categories. CONCLUSION: Many interventions directed toward improving somatic health for patients with SMI have been started. These studies did not apply similar evaluations, and did not use uniform outcome measures of the effect of their interventions. Valuable comparisons on effectiveness are therefore almost impossible.

COPD in the working age population: the economic impact on both patients and government.

OBJECTIVES: To explore the full economic impact, on both patients and government, as a result of COPD in the working age population. METHODS: The economic impact of COPD due to medical treatment, impaired productivity and early retirement was assessed in a cross sectional cost analysis of the Dutch COPD population aged 45-64 years. The costing year was 2009 and input parameters were derived from both national data sources and the international COPD uncovered survey. RESULTS: While direct medical costs for COPD patients of working age were relatively low (€ 91 million), the amount of lost productivity (income) due to early retirement (€ 223 million) exceeded over two times their medical costs. In addition, costs for the government were considerable because of lost tax revenues (€ 77 million) and COPD related disability pensions paid (€ 180 million). Apart from lost productivity due to early retirement, costs due to impaired productivity for working COPD patients were € 63 million. CONCLUSIONS: The costs of COPD for both patients of working age as for the government were considerable, making this population a priority for prevention and intervention programs of healthcare providers, employers and government.

Implementing a Managed Entry Agreement Framework in Cyprus.

INTRODUCTION: The aim of this study is to explore the current practice in Cyprus regarding the introduction and reimbursement of innovative pharmaceuticals through Managed Entry Agreements (MEA), assess its operational context, and suggest approaches toward spanning the knowledge gap consequential to these efforts, especially the barriers of a small country context. AREAS COVERED: The recent introduction of a National Health System (NHS), brought about fundamental reforms in Cyprus' Healthcare sector. Among such reforms, of particular interest, has been the introduction of a Managed Entry Agreements (MEA) mechanism. The first preliminary results indicate that despite being a small and unattractive market, Cyprus can apply a substantial MEA program. Concomitantly, it annotates the need to design an operational framework which should include, the definition of important technical parameters, clear demarcation of the scope, cooperation principles ensuring the effective operation of scientific committees, and clear delineation of what 'value' is. Moreover, in the context of the unified healthcare market, budget transfers should be considered, which could alleviate the inordinate budget impact of new products, which nevertheless will cut down on hospital expenditures. Narrative synthesis and health policy analysis-related resources were used. EXPERT OPINION: The implementation of MEA in Cyprus provides an ideal testing ground for innovative reimbursement approaches. This will streamline the country's efforts toward reimbursement of innovation, while concomitantly add to the collective MEA experience.

Cost-effectiveness of ravulizumab compared with eculizumab for the treatment of paroxysmal nocturnal hemoglobinuria in the Netherlands.

OBJECTIVES: The aim of this study was to evaluate the cost-effectiveness of ravulizumab compared with eculizumab for the treatment of adult patients with paroxysmal nocturnal hemoglobinuria (PNH) in the Netherlands. METHODS: A cost-effectiveness analysis was conducted based on a Markov cohort model simulating the course of patients with PNH with clinical symptom(s) indicative of high disease activity, or who are clinically stable after having been treated with eculizumab for at least the past six months. Costs, quality of life, and the incremental cost-effectiveness ratio (ICER) were estimated over a lifetime horizon from a Dutch societal perspective. Several additional analyses were performed, including a one-way sensitivity analysis, a probabilistic sensitivity analysis, and scenario analysis. RESULTS: When compared with eculizumab, ravulizumab saves €266,833 and 1.57 quality adjusted life years (QALYs) are gained, resulting in a dominant ICER. Drug costs account for the majority of the total costs in both intervention groups. Cost savings were driven by the difference in total treatment costs of ravulizumab compared with eculizumab caused by the reduced administration frequency, accounting for 98% of the total cost savings. The QALY gain with ravulizumab is largely attributable to the improved quality of life associated with less frequent infusions and BTH events. At a willingness-to-pay threshold of €20,000/QALY, there is a 76.6% probability that ravulizumab would be cost-effective. CONCLUSIONS: The cost reduction and QALY gain associated with the lower rates of BTH and less frequent administration make ravulizumab a cost-saving and clinically beneficial substitute for eculizumab for adults with PNH in the Netherlands.
