RESUMO
INTRODUCTION: Haemophilia A (HA) is a congenital bleeding disorder caused by a deficiency/absence of factor VIII (FVIII) and characterised by frequent, acute and prolonged spontaneous or traumatic bleeding events, often leading to haemophilic arthropathy and progressive joint deterioration. HA severity is characterized by endogenous FVIII activity: mild (> 5-40%), moderate (1-5%), or severe (< 1%). HA poses a substantial clinical and socioeconomic burden on people with HA (PWHA), their caregivers, and society. This analysis evaluates clinical and patient-centric outcomes of a cohort of individuals with non-inhibitor HA sampled from France, Germany, Italy, Spain, and the UK in the 'Cost of Haemophilia in Europe: A Socioeconomic Survey II' (CHESS II) study. METHODS: CHESS II was a cross-sectional burden-of-illness study collecting clinical and socioeconomic data on adult (≥ 18 years) individuals with haemophilia A or B of any severity with or without inhibitors from eight European countries. Descriptive analyses were conducted examining physician-reported demographics, clinical and health resource utilisation information. PWHA-reported health-related quality of life (HRQoL) using the EQ-5D-5L and Work Productivity and Activity Impairment (WPAI) were also examined. Outcomes were stratified by HA severity and reported at country level. RESULTS: Demographics and clinical characteristics of the cohort (N = 880) were generally consistent across countries. Individuals with severe HA experienced more frequent bleeding events and joint disease despite broad use of factor replacement therapy long-term prophylaxis. A minority of those with mild or moderate HA also experienced such challenges. HRQoL and workforce participation diminished, and chronic pain increased, with increasing HA severity. CONCLUSION: This analysis provides up-to-date insights on the impact of HA across five European countries. Increasing HA severity was generally associated with worse clinical outcomes, HRQoL and workforce participation. These findings suggest a place for continued evidence-based tailored treatment and clinical management approaches in addressing the residual burden of HA.
RESUMO
BACKGROUND: Haemophilia A (HA; Factor VIII deficiency) is a congenital X-linked bleeding disorder characterized by trauma-related or spontaneous bleeding events, most notably arising within the intraarticular space and resulting in chronic inflammation and degeneration of affected joints. Endogenous clotting factor activity relative to normal levels determines the severity of HA symptoms, as mild (> 5-40%), moderate (1-5%), or severe (< 1%). Within the current environment of rapid evolution in HA management, we seek to understand the interplay of condition severity and health-related quality of life (HRQoL) to characterise and differentiate unmet needs among people with HA (PwHA). METHODS: A generalised linear regression model (GLM) was developed to explore the relationship between HA severity and EQ-5D-5 L index score from adult HA patients sampled in the "Cost of Haemophilia across Europe - a Socioeconomic Survey II" (CHESS II) cross-sectional, retrospective burden of illness study among adults with hereditary haemophilia A or B from eight European countries. HA patients of any severity with no active inhibitors during the 12 months prior to data capture and a completeEQ-5D-5 L response were included. A base GLM model was specified with covariates for demographic and clinical characteristics (age, body mass index, country, employment, HA severity, annual bleeding rate, problem joints, and chronic pain). RESULTS: Of 381 evaluable patients, 221 (58.0%) had severe HA, 96 (25.2%) had moderate HA, and 64 (16.8%) had mild HA. Among the covariates included in the GLM model and after controlling for haemophilia-related outcomes, a significant association was observed between mild HA and higher EQ-5D-5 L index score (average marginal effects, 0.084; p = 0.016) relative to severe HA. Patient country of residence and magnitude of HA-related chronic pain were also associated with significant differences in index scores, with the latter showing a negative relationship with HRQoL outcomes. CONCLUSIONS: Condition severity and chronic pain are significant predictors of HRQoL in PwHA. Durable bleeding protection and effective management of chronic pain have the potential to address unmet treatment needs in this population.

BACKGROUND: The CLN2 Clinical Rating Scale evaluates disease progression in CLN2 disease, an ultra-rare, neurodegenerative disorder with late infantile onset. To validate the Clinical Rating Scale, a comparison with the Pediatric Quality of Life Inventory (PedsQL) was conducted utilising clinical trial data investigating cerliponase alfa use in CLN2 disease. METHODS: Linear regression and mixed effects models were used to investigate the relationship between the Clinical Rating Scale and PedsQL using open-label, single-arm, phase 1/2 (NCT01907087) and ongoing extension study (NCT02485899) data of 23 children with CLN2 disease treated with cerliponase alfa for ≥96 weeks. RESULTS: Correlations between the four Clinical Rating Scale domains were low. Linear mixed effects analyses showed significant correlation between PedsQL and Clinical Rating Scale (Total score or motor-language [ML] score adjusted p-values <0.05), driven by the relationship with the PedsQL Physical domain. A statistically significant relationship was identified between the Clinical Rating Scale motor domain and PedsQL (Total score: adjusted p-value = 0.048, parameter estimate [PE] = 8.10; Physical domain score: adjusted p-value = 0.012; PE = 13.79). CONCLUSIONS: Each domain of the Clinical Rating Scale provides unique information on disease state. Validity of the scale is supported by its relationship with the PedsQL. Among the four domains of the Clinical Rating Scale, motor has the highest correlation to PedsQL, suggesting motor function as a driver of patients' quality of life. The lack of association between the remaining domains of the Clinical Rating Scale and PedsQL suggests that additional disease-specific measures may be needed to fully capture the quality of life impact of CLN2 disease. TRIAL REGISTRATION: NCT01907087, NCT02485899.

INTRODUCTION: The physical pain and disability affecting many people with haemophilia A (PwHA) are known detractors from psychological wellbeing. While psychosocial support is considered a core tenet of the haemophilia comprehensive care structure, the extent to which mental health challenges are detected and monitored by the individuals treating haematologist remains relatively unexplored. AIM: To describe prevalence of anxiety and depression in a real-world cohort of adult PwHA and evaluate the congruence in reporting of anxiety or depression (A/D) between PwHA and their treating physicians. METHODS: Data for PwHA without inhibitors was drawn from the European 'Cost of Haemophilia: A Socioeconomic Survey II' (CHESS II) study. Haematologist-indicated comorbidities of anxiety and depression were unified into a single A/D indicator. The EQ-5D-5L health status measure was used to characterise self-reported A/D, with individuals stratified into two non-mutually exclusive subgroups based on level of A/D reported (Subgroup A: 'some' or above; Subgroup B: 'moderate' or above). RESULT: Of 381 PwHA with evaluable EQ-5D-5L responses, 54% (n = 206) self-reported at least some A/D (Subgroup A) and 17% (n = 66) reported at least moderate A/D (Subgroup B). Patient-physician congruence in A/D reporting was 53% and 76% for Subgroups A and B, respectively. Descriptive analysis suggested that individuals with physician- and/or self-reported A/D experienced worse clinical outcomes (bleeding events, joint disease, chronic pain). CONCLUSION: While adverse clinical outcomes appear to correlate with A/D, self-reports of moderate-severe symptoms occasionally lacked formal recognition from treating physicians. Cross-disciplinary surveillance of mental health issues could improve both psychological and clinical outcomes among PwHA.

Background: New hereditary angioedema (HAE) treatments have become available in recent years for the treatment of HAE due to C1-inhibitor (C1-INH) deficiency, including two subcutaneous (SC) options: a monoclonal antibody (lanadelumab) and a plasma-derived C1-INH concentrate (SC-C1-INH). Limited real-world data on these therapies have been reported. Objective: The objective was to describe new users of lanadelumab and SC-C1-INH, including demographics, healthcare resource utilization (HCRU), costs, and treatment patterns before and after beginning treatment. Methods: This was a retrospective cohort study that used an administrative claims data base. Two mutually exclusive cohorts of adult (ages ≥18 years) new users of lanadelumab or SC-C1-INH with ≥180 days of continuous use were identified. HCRU, costs, and treatment patterns were assessed in the 180-day period before the index date (new treatment use) and up to 365 days after the index date. HCRU and costs were calculated as annualized rates. Results: Forty-seven patients who used lanadelumab and 38 patients who used SC-C1-INH were identified. The most frequently used on-demand HAE treatments at baseline were the same for both cohorts: bradykinin B2 antagonists (48.9% of the patients on lanadelumab, 52.6% of the patients on SC-C1-INH) and C1-INHs (40.4% of the patients on lanadelumab, 57.9% of the patients on SC-C1-INH). More than 33% of the patients continued to fill on-demand medications after treatment initiation. Annualized angioedema-associated emergency department visits and hospitalizations decreased after initiation of treatment, from 1.8 to 0.6 for the patients on lanadelumab and from 1.3 to 0.5 for the patients on SC-C1-INH. Annualized total healthcare costs after treatment initiation in the database were $866,639 and $734,460 for the lanadelumab and SC-C1-INH cohorts, respectively. Pharmacy costs accounted for >95% of these total costs. Conclusion: Although HCRU decreased after the initiation of treatment, angioedema-associated emergency department visits and hospitalizations and on-demand treatment fills were not completely eliminated. This indicates ongoing disease and treatment burden despite use of modern HAE medicines.

BACKGROUND: Conventional cost-effectiveness analysis [CEA] using cost per QALY thresholds may counteract other incentives introduced to foster development of treatments for rare and ultra-rare diseases. Therefore, alternative economic evaluation methods were explored, namely Discrete Choice Experiment Willingness to Pay (DCE-WTP) and Relative Social Willingness to Pay (RS-WTP), to value interventions for an ultra-rare childhood disease, Neuronal Ceroid Lipofuscinosis type 2 (CLN2). RESEARCH DESIGN AND METHODS: Treatment for CLN2 was valued from a citizen's ('social') perspective using DCE-WTP and RS-WTP in a survey of 4,009 United Kingdom [UK] adults. Three attributes (initial quality of life, treatment effect, and life expectancy) were used in both analyses. For DCE-WTP, a cost attribute (marginal income tax increase) was also included. Optimal econometric models were identified. RESULTS: DCE-WTP indicated that UK adults are willing to pay incremental increases through taxation for improvements in CLN2 attributes. RS-WTP identified a willingness to allocate >40% of a pre-assigned healthcare budget to prevent child mortality and approximately 15% for improved health status. CONCLUSIONS: Both techniques illustrate substantive social WTP for CLN2 interventions, despite the small number of children benefitting. This highlights a gap between UK citizens' willingness to spend on rare disease interventions and current funding policies.

INTRODUCTION: Few studies have examined the real-world impact of haemophilia on daily activities and work productivity in people with severe haemophilia A (PWSHA). AIM: To determine clinical attributes and treatment characteristics associated with impairment in daily activities and work among PWSHA using the patient-reported Work Productivity and Activity Impairment-General Health Questionnaire (WPAI-GH). METHODS: PWSHA were asked to complete the WPAI-GH as part of the Cost of Haemophilia in Europe: A Socioeconomic Survey (CHESS) study. Outcomes were determined for activity impairment (AI), absenteeism, presenteeism and overall work productivity loss (WPL). Descriptive statistics and regression analyses were used to evaluate the association between these outcomes and clinical and treatment attributes. RESULTS: Overall, 376 participants completed the AI element of WPAI-GH; 175 were employed and thus also reported on work impact. Mean ± standard deviation scores were as follows: AI = 34.2% ± 25.8%; absenteeism = 0.06% ±0.2%; presenteeism = 26.8% ± 22.4%; WPL = 28.6% ± 24.0%. Increased AI and WPL were associated with high haemophilia-related morbidity, measured both as chronic pain (p < .001 for both) and joint synovitis (AI: p <0.001; WPL: p = .017). In descriptive and multivariate analyses, lifelong prophylaxis was associated with reduced AI (p < .001 and p = .031, respectively); high therapy adherence was associated with reduced AI (p = .001 and p = .012, respectively) and with reduced WPL (p < .001 and p = .012, respectively). CONCLUSION: The WPAI-GH identified haemophilia-related morbidity and treatment characteristics, including therapy regimen and adherence, as key attributes impacting functional impairment and work contributions of PWSHA. Early prophylactic intervention and greater adherence to therapy may lead to lower AI and WPL in PWSHA.

BACKGROUND: Utility studies enable preference-based quantification of a disease's impact on patients' health-related quality of life (HRQoL). It is often difficult to obtain utility values for rare, neurodegenerative conditions due to cognitive burden of direct elicitation methods, and the limited size of patient/caregiver populations. CLN2 disease (neuronal ceroid lipofuscinosis type 2) is an ultra-rare, progressive condition, for which there are no published utility data fully capturing all disease stages. This case study demonstrates how utility values can be estimated for ultra-rare paediatric diseases by asking clinicians to complete EQ-5D-5L questionnaires based on vignettes describing the stages of CLN2 disease. METHODS: An indirect elicitation method using proxy-reporting by clinical experts was adopted. Eighteen vignettes were developed, describing nine progressive disease stages as defined by motor and language domain scores of the CLN2 Clinical Rating Scale, in individuals treated with cerliponase alfa or standard care. Eight clinical experts with experience of treating CLN2 disease with cerliponase alfa and current standard care completed the proxy version 2 EQ-5D-5L online after reading these vignettes. Resulting scores were converted to EQ-5D-5L utility values for each disease stage, using UK, German and Spanish value sets. RESULTS: Utility values, which are typically anchored by 0 (equivalent to death) and 1 (full health), decreased with CLN2 disease progression (results spanned the maximum range of the utility scale). Assigned utility values were consistently higher for patients receiving cerliponase alfa than standard care; differences were statistically significant for the 6 most severe disease stages (p < 0.05). Analysis of the individual dimensions of the EQ-5D-5L showed that greatest differences between patients treated with cerliponase alfa and standard care occurred in the pain dimension (differences in mean scores ranged between no difference and 1.8), with notable differences also observed in the anxiety/depression dimension (differences in mean scores ranged between 0.1 and 1.0). CONCLUSIONS: This study demonstrates a feasible methodology for eliciting utility values in CLN2 disease, indicating HRQoL declines with disease progression. Vignettes describing patients receiving cerliponase alfa were consistently assigned higher utility values for the same disease state, suggesting this treatment improves HRQoL compared with standard care. Trial registration NCT01907087, NCT02485899.

BACKGROUND: Joint damage remains a major complication associated with haemophilia and is widely accepted as one of the most debilitating symptoms for persons with severe haemophilia. The aim of this study is to describe how complications of haemophilia such as target joints influence health-related quality of life (HRQOL). METHODS: Data on hemophilia patients without inhibitors were drawn from the 'Cost of Haemophilia across Europe - a Socioeconomic Survey' (CHESS) study, a cost-of-illness assessment in severe haemophilia A and B across five European countries (France, Germany, Italy, Spain, and the UK). Physicians provided clinical and sociodemographic information for 1285 adult patients, 551 of whom completed corresponding questionnaires, including EQ-5D. A generalised linear model was developed to investigate the relationship between EQ-5D index score and target joint status (defined in the CHESS study as areas of chronic synovitis), adjusted for patient covariates including socio-demographic characteristics and comorbidities. RESULTS: Five hundred and fifteen patients (42% of the sample) provided an EQ-5D response; a total of 692 target joints were recorded across the sample. Mean EQ-5D index score for patients with no target joints was 0.875 (standard deviation [SD] 0.179); for patients with one or more target joints, mean index score was 0.731 (SD 0.285). Compared to having no target joints, having one or more target joints was associated with lower index scores (average marginal effect (AME) -0.120; SD 0.0262; p < 0.000). CONCLUSIONS: This study found that the presence of chronic synovitis has a significant negative impact on HRQOL for adults with severe haemophilia. Prevention, early diagnosis and treatment of target joints should be an important consideration for clinicians and patients when managing haemophilia.

OBJECTIVES: Target joints are a common complication of severe haemophilia. While factor replacement therapy constitutes the majority of costs in haemophilia, the relationship between target joints and non drug-related direct costs (NDDCs) has not been studied. METHODS: Data on haemophilia patients without inhibitors was drawn from the 'Cost of Haemophilia across Europe - a Socioeconomic Survey' (CHESS) study, a cost assessment in severe haemophilia A and B across five European countries (France, Germany, Italy, Spain, and the United Kingdom) in which 139 haemophilia specialists provided demographic and clinical information for 1285 adult patients. NDDCs were calculated using publicly available cost data, including 12-month ambulatory and secondary care activity: haematologist and other specialist consultant consultations, medical tests and examinations, bleed-related hospital admissions, and payments to professional care providers. A generalized linear model was developed to investigate the relationship between NDDCs and target joints (areas of chronic synovitis), adjusted for patient covariates. RESULTS: Five hundred and thirteen patients (42% of the sample) had no diagnosed target joints; a total of 1376 target joints (range 1-10) were recorded in the remaining 714 patients. Mean adjusted NDDCs for persons with no target joints were EUR 3134 (standard error (SE) EUR 158); for persons with one or more target joints, mean adjusted NDDCs were EUR 3913 (SE EUR 157; average mean effect EUR 779; p < 0.001). CONCLUSIONS: Our analysis suggests that the presence of one or more target joints has a significant impact on NDDCs for patients with severe haemophilia, ceteris paribus. Prevention and management of target joints should be an important consideration of managing haemophilia patients.
RESUMO
BACKGROUND: The benefits of minimally invasive partial nephrectomy (PN) for localised renal cancers are well established. Outcomes and hospital activity following PN have not been studied for the English National Health System, despite a growing use of robotic-assisted PN (RAPN). OBJECTIVE: To compare 90-d complication rates and 1-yr hospital activity and costs following PN using routinely-collected national data. DESIGN, SETTING, AND PARTICIPANTS: We analysed Hospital Episode Statistics data for 4275 patients undergoing open PN (OPN), laparoscopic PN, or RAPN between October 2008 and September 2014. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Hospital activity and costs estimated using multivariate Generalised Linear Models. Logistic regression was used to model postoperative complications. RESULTS AND LIMITATIONS: Compared with RAPN, OPN experienced more frequent 90-d readmissions for wound-related complications (n=68 vs n=3, p=0.014) and postoperative infections (n=151 vs n=11, p=0.045). One-year inpatient admissions were higher in OPN (incidence rate: 1.628 vs 0.928, p=0.004). Outcomes in laparoscopic PN and RAPN were equivalent. In comparison to OPN, RAPN was associated with lower complication-related costs at 90 d (mean £317.21 vs £129.29, p=0.002) and total costs at 1 yr (mean £2998.55 vs £2089.37, p=0.024). Limitations were the absence of clinical indicators for risk adjustment. CONCLUSIONS: Hospital activity is significantly lower in the year immediately following RAPN compared with OPN. This is driven in part by a reduction in postoperative complications requiring readmission, reflecting lower total costs. PATIENT SUMMARY: We analysed national data for 4275 patients undergoing partial nephrectomy via open, laparoscopic, or robotic assisted laparoscopic surgery in England over a 6-yr period. Robotic assisted laparoscopic surgery was associated with fewer 90-d complications and lower total costs at 1-yr postintervention.

BACKGROUND: Severe haemophilia is associated with major psychological and economic burden for patients, caregivers, and the wider health care system. This burden has been quantified and documented for a number of European countries in recent years. However, few studies have taken a standardised methodology across multiple countries simultaneously, and sought to amalgamate all three levels of burden for severe disease. The overall aim of the 'Cost of Haemophilia in Europe: a Socioeconomic Survey' (CHESS) study was to capture the annualised economic and psychosocial burden of severe haemophilia in five European countries. A cross-section of haemophilia specialists (surveyed between January and April 2015) provided demographic and clinical information and 12-month ambulatory and secondary care activity for patients via an online survey. In turn, patients provided corresponding direct and indirect non-medical cost information, including work loss and out-of-pocket expenses, as well as information on quality of life and adherence. The direct and indirect costs for the patient sample were calculated and extrapolated to population level. RESULTS: Clinical reports for a total of 1,285 patients were received. Five hundred and fifty-two patients (43% of the sample) provided information on indirect costs and health-related quality of life via the PSC. The total annual cost of severe haemophilia across the five countries for 2014 was estimated at EUR 1.4 billion, or just under EUR 200,000 per patient. The highest per-patient costs were in Germany (mean EUR 319,024) and the lowest were in the United Kingdom (mean EUR 129,365), with a study average of EUR 199,541. As expected, consumption of clotting factor replacement therapy represented the vast majority of costs (up to 99%). Indirect costs are driven by patient and caregiver work loss. CONCLUSIONS: The results of the CHESS study reflect previous research findings suggesting that costs of factor replacement therapy account for the vast majority of the cost burden in severe haemophilia. However, the importance of the indirect impact of haemophilia on the patient and family should not be overlooked. The CHESS study highlights the benefits of observational study methodologies in capturing a 'snapshot' of information for patients with rare diseases.

OBJECTIVES: To evaluate postoperative health resource utilisation and secondary care costs for radical prostatectomy and partial nephrectomy in National Health Service (NHS) hospitals in England, via a comparison of robot-assisted, conventional laparoscopic and open surgical approaches. PATIENTS AND METHODS: We retrospectively analysed the secondary care records of 23 735 patients who underwent robot-assisted (RARP, n = 8 016), laparoscopic (LRP, n = 6 776) or open radical prostatectomy (ORP, n = 8 943). We further analysed 2 173 patients who underwent robot-assisted (RAPN, n = 365), laparoscopic (LPN, n = 792) or open partial nephrectomy (OPN, n = 1 016). Postoperative inpatient admissions, hospital bed-days, excess bed-days and outpatient appointments at 360 and 1 080 days after surgery were reviewed. RESULTS: Patients in the RARP group required significantly fewer inpatient admissions, hospital bed-days and excess bed-days at 360 and 1 080 days than patients undergoing ORP. Patients undergoing ORP had a significantly higher number of outpatient appointments at 1 080 days. The corresponding total costs were significantly lower for patients in the RARP group at 360 days (£1679 vs £2031 for ORP; P < 0.001) and at 1 080 days (£3461 vs £4208 for ORP; P < 0.001). In partial nephrectomy, Patients in the RAPN group required significantly fewer inpatient admissions and hospital bed-days at 360 days compared with those in the OPN group; no significant differences were observed in outcomes at 1 080 days. The corresponding total costs were lower for patients in the RAPN group at 360 days (£779 vs £1242 for OPN, P = 0.843) and at 1 080 days (£2122 vs £2889 for ORP; P = 0.570). For both procedure types, resource utilisation and costs for laparoscopic surgeries lay at the approximate midpoint of those for robot-assisted and open surgeries. CONCLUSION: Our analysis provides compelling evidence to suggest that RARP leads to reduced long-term health resource utilisation and downstream cost savings compared with traditional open and laparoscopic approaches. Furthermore, despite the limitations that arise from the inclusion of a small sample, these results also suggest that robot-assisted surgery may represent a cost-saving alternative to existing surgical options in partial nephrectomy. Further exploration of clinical cost drivers, as well as an extension of the analysis into subsequent years, could lend support to the wider commissioning of robot-assisted surgery within the NHS.

PURPOSE: We evaluated the long-term medical and economic benefits of vagus nerve stimulation (VNS) therapy for 704 adults and children with epilepsy. A pre-post analysis was conducted using Hospital Episode Statistics (HES) data (April 2008-July 2014). Seven hundred and four patients with epilepsy diagnoses (ICD-10 G40.x or G41.x), one or more procedures for vagus nerve stimulator implantation, and six or more months of available HES data pre- and post-VNS were selected. The pre-VNS period averaged 39.1 months. The post-VNS period extended from implantation to device removal, death, or study end (up to six years), with a mean duration of 36.4 months. Incidence rate ratios (IRRs) and cost differences (£2014) were estimated. Mean age was 28.3 years. RESULTS: Inpatient admissions decreased post-VNS compared with pre-VNS (adjusted IRR=0.81, P<0.001). Overall, outpatient consultations increased post-VNS compared with pre-VNS (adjusted IRR=1.34, P<0.001). However, outpatient consultations exhibited a decreasing trend in the post-VNS period (adjusted IRR=0.96, P<0.001), suggesting that much of the increased outpatient activity in the post-VNS period relates to follow-up management of the VNS device in the immediate period following implantation, with comparable outpatient resource burden at 36 months post-VNS. No significant changes in clinical events were observed; however, average epilepsy-related medical costs were lower post-VNS than pre-VNS (adjusted cost difference -£110 quarterly, P=0.001). CONCLUSIONS: Vagus nerve stimulation is associated with increased outpatient resource utilization and decreased inpatient admissions, with a reduction in long-term epilepsy-related medical costs post-implantation.
