Outbreaks of meningococcal disease have caused devastation worldwide. Effective vaccines have not been used routinely, due to perceived limitations of the duration of effectiveness as well as immunogenicity when administered during infancy. Given the sporadic nature of outbreaks, the optimal use of these vaccines to control both short-term epidemic and endemic meningococcal disease has been the subject of much debate. ⋯ However, depending on the disease incidence and the ability to deliver vaccines, the polysaccharide vaccine can be cost effective for preventive strategies when given prior to the start of outbreaks, either through presumptive vaccination or through a modified routine delivery strategy. Economic analyses of mass immunisation campaigns and modelled routine vaccination suggest that routine use of meningococcal vaccines for preventive strategies could be within the range of cost-effective public health interventions in those regions of the world where meningococcal disease is endemic. This includes the meningococcal belt of Africa, the Sahelian region.

There is a lack of emphasis on health-related QOL (HR-QOL) changes associated with acute exacerbation of chronic bronchitis (CB) or chronic obstructive pulmonary disease (COPD). The aim of this review is to examine the use of HR-QOL instruments to evaluate acute exacerbation of CB or COPD, so as to form recommendations for future research. A literature search of papers published between 1966 and July 2003 identified more than 300 articles that used acute exacerbation of CB or COPD as the search term. ⋯ There is a need for studies of treatments for acute exacerbation of CB or COPD to include an appropriate HR-QOL instrument to aid in the stratification of patients so as to target the right treatment to the right patient group. While a new instrument could be developed to measure HR-QOL during acute exacerbation of CB or COPD, currently available disease-specific measures such as the CRQ and the SGRQ appear to be acceptable to patients during acute exacerbation. However, the recall period of the SGRQ symptoms component should be shortened to make it more appropriate for use during acute exacerbation.

To develop a Markov model that allows the cost effectiveness of interventions in patients with chronic obstructive pulmonary disease (COPD) to be estimated, and to apply the model to investigate the cost effectiveness of an inhaled corticosteroid/long-acting beta(2)-adrenoceptor agonist (beta(2)-agonist) combination (salmeterol/fluticasone propionate) versus usual care. ⋯ This Markov model allows, for the first time, a means of estimating the long-term cost effectiveness and cost utility of interventions for COPD. Initial evidence suggests that for patients with poorly reversible COPD and a documented history of frequent COPD exacerbations, the addition of salmeterol (a long-acting beta(2)-agonist) to fluticasone propionate (an inhaled corticosteroid) is potentially cost effective from the Canadian healthcare payer's perspective. However, the precision of this estimate will be improved when additional data are available from clinical trials such as the ongoing TORCH (TOwards a Revolution in COPD Health) study.

This study provides the results of a cost-effectiveness analysis of levetiracetam as an adjunctive treatment for refractory epilepsy from the Canadian Ministry of Health perspective. The main objective is to estimate the expected cost-effectiveness ratio expressed as the incremental cost per seizure-free day gained when using levetiracetam. In addition, this study examines the potential savings that might result by reducing the number of surgical evaluations and surgery when using levetiracetam. ⋯ The economic analysis presented in this paper suggests, given a wide range of assumptions, that the increased cost of treating patients (with refractory epilepsy) with levetiracetam may be partially offset by a reduction in other direct medical costs (from the Canadian Ministry of Health perspective), as a consequence of an increase in the number of seizure-free days. Moreover, potential cost savings may be foreseen when it is assumed that levetiracetam may reduce the number of candidates for surgical evaluation and surgery through a reduction of seizure frequency.

Schizophrenia is one of the most expensive psychiatric conditions because of high direct and indirect costs associated with the nature of the illness, its resistance to treatment and the consequences of relapse. Long-acting risperidone is a new formulation of an atypical antipsychotic drug that also offers the improvements in compliance associated with haloperidol depot. The aim of this simulation study was to compare the benefits and costs of three pharmacological treatment strategies comprising first-line treatment with long-acting risperidone injection, a haloperidol depot or an oral atypical antipsychotic agent, over a 5-year period in Germany. ⋯ Sensitivity analyses showed that the results were robust and mainly sensitive to changes in the reported relative effectiveness of atypical and conventional formulations for preventing symptom recurrence, and in the relative compliance with oral and long-acting formulations. In this model, long-acting risperidone is a dominant strategy compared with a haloperidol depot or oral atypical antipsychotic agent, being both more effective and less costly over a 5-year period. Results for long-acting risperidone are even more favourable among patients at high risk of being noncompliant or with more severe disease.
