A model was developed to estimate costs and clinical effectiveness of fondaparinux compared with enoxaparin after hip fracture surgery in Sweden. Outcomes and costs of venous thromboembolism (VTE)-related care from a health care perspective were incorporated, with symptomatic deep-vein thrombosis and pulmonary embolism, recurrent VTE, post-thrombotic syndrome, major haemorrhage and all-cause death being included. Event probabilities were derived from fondaparinux clinical trial data and published data. VTE-related resource use and associated costs as well as costs of prophylaxis were based on local Swedish data. Extended prophylaxis with fondaparinux could avoid an additional 28 symptomatic VTE per 1,000 patients compared with extended prophylaxis with enoxaparin in hip fracture surgery patients. Although the prophylaxis costs were higher in the fondaparinux group, these were offset by the lower costs associated with treating fewer VTE, which thus indicates that extended fondaparinux prophylaxis is the dominant alternative when compared with enoxaparin in hip fracture surgery.

Hypoglycemia is an often underrecognized side effect of type 2 diabetes therapy. This study assessed the burden of hypoglycemia in this population in Sweden and included 309 patients aged 35 years or older and treated with insulin and/or oral antidiabetic agents. Data were gathered through patient questionnaires/interviews and chart reviews. The results showed that 115 patients (37%) reported symptoms of hypoglycemia during the preceding month. Patients with hypoglycemia were more affected by their diabetes, reported lower general health, and were more anxious about hypoglycemia than those without hypoglycemia. The direct and indirect costs of hypoglycemia per patient with hypoglycemic symptoms were estimated to be U.S. $12.9 and $14.1, respectively, for a 1-month period. The results indicate that hypoglycemia is common, and that a reduction in these symptoms, without reducing glycemic control, may improve patient well-being and possibly also reduce cost.

Deep-vein thrombosis and pulmonary embolism are important causes of morbidity and mortality among patients undergoing major surgery. Fondaparinux is a new antithrombotic agent for use in prophylaxis, and this study compared its cost and effect vs. enoxaparin as prophylactic treatment in patients undergoing total knee replacement, total hip replacement, or hip-fracture surgery in Sweden. The analyses were based on a simulation model. Swedish data on cost for deep-vein thrombosis and pulmonary embolism were obtained from a large sample of patients undergoing major orthopedic surgery. The relative risk reduction for treatment with fondaparinux was estimated from results of four recently published clinical trials. The base case analyses showed that fondaparinux was cost saving and more effective than enoxaparin after total knee replacement and hip-fracture surgery and had costs per prevented venous thromboembolism of about 239 after total hip replacement. Fondaparinux is thus more cost-effective than enoxaparin as prophylactic treatment in patients undergoing major surgery in Sweden.
