The cost of prevalent and incident cardiovascular disease in people with type 2 diabetes in Scotland: data from the Scottish Care Information-Diabetes Collaboration.

AIM: To compare costs for three groups of people with type 2 diabetes, those at high risk of future cardiovascular disease, those without cardiovascular disease and those with established cardiovascular disease, and to also compare costs incurred by people with type 2 diabetes with an incident cardiovascular disease event with those who remain incident event-free over a 3-year period. METHODS: Data about people with type 2 diabetes in Scotland were obtained from the Scottish Care Information Diabetes registry. Data linkage was used to retrieve information on healthcare utilization, care home use and deaths. Productivity effects were estimated for those of non-pensionable age. We estimated costs over 12 months (prevalent cardiovascular disease) and 3 years from incident cardiovascular disease event. RESULTS: Mean annual cost per person with established cardiovascular disease was £6900, £3300 for a person at high risk of future cardiovascular disease, and £2500 for a person without cardiovascular disease and not at high risk. In year 1, the cost of an incident cardiovascular disease event was £16 700 compared with £2100 for people without an incident event. Over 2 years, the cumulative costs were £21 500 and £4200, and by year 3, £25 000 and £5900, respectively. CONCLUSIONS: Cardiovascular disease in people with type 2 diabetes places a significant financial burden on healthcare and the wider economy. Our results emphasize the financial consequences of cardiovascular disease prevention strategies.

Perioperative management of haemophilia B: A critical appraisal of the evidence and current practices.

BACKGROUND: While there is substantial literature addressing the principles of general management of haemophilia, literature on perioperative management of haemostasis is scarce. OBJECTIVE: The aim of this study was to better understand perioperative management among congenital haemophilia B patients (without inhibitors) and to gain insights into real-world surgical practices. METHOD: A systematic literature review, with an emphasis on haemophilia B, was conducted using EMBASE® , Medline® and the Cochrane Library. Studies from 1974 to June 2015 were accessed, and 132 studies were eligible for the full-study review. An international expert panel with five haematologists and one surgeon reviewed the resulting literature and provided further insights. RESULTS: The literature review revealed that documented experience in the perioperative management of bleeding risk in haemophilia B patients is relatively scarce. Therefore, the review was amended to provide a comprehensive overview of the perioperative management for haemophilia A and B patients; the expert panel applied a particular focus to haemophilia B. Several gaps were identified in the literature including the lack of consensus on defining surgery in terms of bleeding risk, optimal factor levels during surgery and lack of robust evidence on surgical outcomes. The ensuing discussions with the expert panel provided validation of some of the results from the systematic literature review and proposed future directions for perioperative management. Suggestions included collaboration with haemophilia treatment centres (HTCs) to collect real-world data on perioperative management, establishing the need for optimal factor level monitoring practice, and the appropriate adoption of extended half-life products in clinical settings.

Improvement in health-related quality of life in patients with haemophilia B treated with nonacog beta pegol, a new extended half-life recombinant FIX product.

INTRODUCTION: Health-related quality of life (HRQoL) of individuals with haemophilia has greatly improved with the use of factor replacement and routine prophylaxis. AIM: To explore the HRQoL of individuals with haemophilia B treated with nonacog beta pegol, an extended half-life recombinant factor IX, in a single-blind, randomized multinational phase III pivotal trial (paradigm(™) 2) and its open-label extension (paradigm(™) 4). METHODS: In the pivotal trial, adolescents and adults with haemophilia B were allocated to 28-week on-demand treatment or randomized to 52 weeks of prophylaxis with 10 or 40 IU kg(-1) nonacog beta pegol administered every seven days. In the extension trial, patients could continue on the same treatment or switch to the alternate dosing regimen at any time. HRQoL was assessed with the HAEMO-QOL/HAEM-A-QOL age-specific questionnaires and the EQ-5D. RESULTS: In the pivotal trial, adults receiving 40 IU kg(-1) prophylaxis reported significant improvements in the 'HAEM-A-QOL Total' score (-6.4 ± 8.5, P = 0.017) and in 'Sport' (-15.3 ± 8.5, P = 0.020), 'Feeling' (-15.2 ± 18.3, P = 0.010) and 'Partnership' (-9.6 ± 15.5, P = 0.046) domain scores; no significant improvements were seen in the other arms. At the pivotal trial end, fewer patients reported problems in the EQ-5D 'Mobility' and 'Pain/Discomfort' dimensions, in particular those receiving prophylaxis. In the extension trial, adult patients switching from 10 to 40 IU kg(-1) prophylaxis showed significant improvements in 'HAEM-A-QOL Total' score (-12.5 ± 8.7, P = 0.016) and 'Physical health' domain (-23.1 ± 14.4, P = 0.016). CONCLUSION: Prophylactic treatment with nonacog beta pegol 40 IU kg(-1) once weekly leads to HRQoL benefits in individuals with haemophilia B; this might be related to fewer bleeding episodes and higher FIX activity levels.
