BACKGROUND Human papillomavirus (HPV) vaccine may be commercially available in a few years. We explored the clinical benefits and cost-effectiveness of introducing an HPV16/18 vaccine in a population with an organized cervical cancer screening program. METHODS A computer-based model of the natural history of HPV and cervical cancer was used to project(More)
BACKGROUND The use of network meta-analysis has increased dramatically in recent years. WinBUGS, a freely available Bayesian software package, has been the most widely used software package to conduct network meta-analyses. However, the learning curve for WinBUGS can be daunting, especially for new users. Furthermore, critical appraisal of network(More)
OBJECTIVES To (i) quantify the cost of multiple sclerosis (MS) to the Canadian health care system and society; (ii) measure health utility in MS patients, and (iii) examine the influence of disability on patient utility and health care costs. MATERIALS AND METHODS A comprehensive patient survey and chart review of relapsing MS patients in remission,(More)
The object of our study is to project the impact of a prophylactic vaccine against persistent human papillomavirus (HPV)-16/18 infection on age-specific incidence of invasive cervical cancer. We developed a computer-based mathematical model of the natural history of cervical carcinogenesis to incorporate the underlying type-specific HPV distribution within(More)
BACKGROUND AND OBJECTIVE Intensive insulin therapy improves glycosylated haemoglobin (Hb(A1C)) levels and delays the onset of long-term diabetes-related complications. Current treatment guidelines recommend maintaining a glycosylated haemoglobin (Hb(A1C)) of < or = 7% in patients with type 1 and 2 diabetes mellitus. However, the risk of hypoglycaemia(More)
Assessing the cost-effectiveness of long-term treatment for osteoporosis requires use of mathematical models to estimate health effects and costs for competing interventions. The primary motivations for model-based analyses include the lack of long-term clinical trial outcome data and the lack of data comparing all relevant treatments within randomized(More)
BACKGROUND AND OBJECTIVES The aim of this study was to examine the cost-effectiveness of adding nucleic acid testing (NAT) to serological (antibody and antigen) screening protocols for donated blood in the United States (US) with the purpose of reducing the risks of transfusion-transmission of hepatitis B virus (HBV), hepatitis C virus (HCV) and human(More)
BACKGROUND A rise in gastrointestinal (GI) adverse events (AEs) and a decline in bone mineral density (BMD) was observed in patients previously tolerant to brand alendronate shortly after generic versions were introduced in July 2005 to the Canadian market. The objective of our study was to quantify changes in AE rates and BMD scores, as well as associated(More)
OBJECTIVE Simulation models are often used to assess cost-effectiveness of osteoporosis therapies. Many cost-effectiveness analyses are interested in a subset of the general population, such as high-risk patients. As the analyses are very sensitive to the assumed risk of fracture, it is imperative that the rates accurately reflect the fracture risk in the(More)
BACKGROUND To determine the efficacy of immunoglobulin free light chain (FLC) removal by high cut-off haemodialysis (HCO-HD) as an adjuvant treatment to chemotherapy for patients with acute kidney injury complicating multiple myeloma (MM). METHODS Sixty-seven patients with dialysis-dependent renal failure secondary to MM were treated with HCO-HD and(More)
