- The objective was to estimate the burden of osteoporosis in Sweden based on current clinical practice and the cost-effectiveness of improvements in the management of osteoporosis over the clinical management compared to current clinical practice. Results showed that better compliance to treatment guidelines is associated with better projected outcomes and cost-savings.IntroductionThe purpose of this study is to estimate the burden of osteoporosis in Sweden based on current clinical practice and the cost-effectiveness of improvements in the management of osteoporosis over the clinical management compared to current clinical practice.MethodsThe analysis was carried out using a model that simulates the individual patients considered for pharmacological treatment during 1 year and their projected osteoporosis treatment pathway, quality-adjusted life years (QALYs) and costs over their remaining lifetime. All patients regardless of treatment or no treatment were simulated. Information on current management of osteoporosis in terms of patient characteristics and treatment patterns were derived from a Swedish osteoporosis research database based on national registers and patient records. Current (standard) clinical management was compared with alternative scenarios mirroring Swedish treatment guidelines.ResultsThe national burden in terms of lost QALYs was estimated at 14,993 QALYs and the total economic cost at €776M. Scenario analyses showed that 382–3864 QALYs could be gained at a cost/QALY ranging from cost-saving to €31368, depending on the scenario. The margin of investment, i.e. the maximum amount that could be invested in the healthcare system to achieve these improvements up to the limit of the willingness to pay/QALY, was estimated at €199M on a population level (€3,634/patient).ConclusionsThe analysis showed that better compliance to treatment guidelines is associated with better projected outcomes and cost-savings. From a cost-effectiveness perspective, there is also considerable room for investment to achieve these improvements in the management of osteoporosis.

Oxygen annealing effect of photoelectron spectra in SrBi2Ta2O9 film
- 2002

Ingår i: Japanese Journal of Applied Physics. - 0021-4922 .- 1347-4065. ; 41:11B, s. 6797-6802

Tidskriftsartikel (refereegranskat)abstract
- Photoelectron spectra have been studied to clarify O-2-annealing effects on the band diagram of the metal-SrBi2Ta2O9 (SBT) junction and ionization energy of SBT films deposited by the pulsed laser, deposition (PLD) method. Photoemission spectra obtained by ultraviolet light irradiation have a threshold of 5.90 eV for the as-deposited SBT film and 5.56 eV for the O-2-annealed one. This shift of the threshold indicates that the annealing treatment has increased the Fermi level by 0.34 eV. On the assumption of a 4.2 eV band gap and 3.5 eV electron affinity for the SBT, as-deposited SBT has been estimated to give a 0.60 eV lower barrier height for holes than that for electrons, which is possibly because of, insufficiently oxidized (Bi2O2)(2+) layers as indicated by X-ray photoelectron spectroscopy (XPS). After annealing in O-2, however, barrier height energies for holes and electrons become closer to each other. These results agree with our previous studies which have reported that the O-2-annealing suppressed the leakage current through SBT and improved the retention characteristics of the metal-ferroelectric-insulator-semiconductor structure.
