    Objective: To gather data about the medical and non-medical health service in patients suffering from post-stroke spasticity of the upper limb and evaluate treatment effectiveness and tolerability as well as costs over the treatment period of one year. Methods: Prospective, non-interventional, multicenter, parallel-group study comparing effectivenessand costs of incobotulinumtoxinA (INCO) treatment (n = 118) to conventional (CON) antispastic therapy (n = 110) for upper limb spasticity after stroke in 47 clinical practices across Germany over a 1-year treatment period. IncobotulinumtoxinA was applied according to the individual treatment algorithms of each participating site and additional antispastic treatments were allowed. Primary efficacy objective was the reduction of the muscle tone measured by Ashworth scale. Responder analyses and logistic regressions were performed. Quality of life, measured by SF-12 questionnaire and functional disability were assessed. Besides calculating treatment costs, a cost-utility analysis was performed. Results: Responder rates of all muscle groups of the upper extremities were significantly higher in the treatment group (62.9-86.2 % vs. 15.5-26.9 %, p < 0.01). Total health service costs were twice as high in the INCO group, however cost-utility ratios were consistently superior compared to the control group. Lowest incremental costs were documented to improve the 'physical health' dimension in quality of life. Conclusion: Higher responder rates, higher increases in quality of life and superior cost-utility ratios in the BoNT/A-treatment group underline guideline recommendations for botulinum toxin A treatment in focal or segmental spasticity. Results may partially be influenced by different patient demographics or disease severity at study entry

    Introduction: Chronic diseases substantially contribute to the continuous increase in health care expenditures, including type-2 diabetes mellitus as one of the most expensive chronic diseases. Arterial hypertension presents a risk factor for the development of type-2 diabetes mellitus. Numerous analyses have demonstrated that antihypertensive therapies promote the development of type-2-diabetes mellitus. Studies indicate, that the application of angiotensin converting enzyme (ACE) inhibitors and angiotensin-receptor-blockers (ARB) lead to less new-onset diabetes compared to beta-blockers, diuretics and placebo. Given that beta-blockers and diuretics impair the glucose metabolism, the metabolic effects of different antihypertensive drugs should be regarded; otherwise not only the disease itself, but also antihypertensive therapies may promote the development of new-onset diabetes. Even though, the cost of ACE inhibitors and ARB are higher, the use in patients with metabolic disorders could be cost-effective in the long-term if new-onset diabetes is avoided. Objectives: To evaluate which class of antihypertensive agents promote the development or the manifestation of type-2 diabetes mellitus. How high is the incidence of new-onset diabetes during antihypertensive therapy and how is treatment-induced type-2 diabetes mellitus evaluated clinically? Which agents are therefore cost-effective in the long term? Which ethical, social or legal aspects should be regarded?MethodsA systematic literature review was conducted including clinical trials with at least ten participants which reported new-onset diabetes in the course of antihypertensive treatment. The trials had to be published after 1966 (after 2003 for economic publications) in English or German. Results: A total of 34 clinical publications meet the inclusion criteria. Of these, eight publications focus on the development of diabetes mellitus under treatment with diuretic and/or beta-blockers, six publications focused on ACE inhibitors alone or in combination with calcium-channel-blockers, ten publications on ARB and/or ACE inhibitors with respect to their effects on new-onset diabetes or their preventive aspects. Furthermore, five publications investigate the role of calcium-channel-antagonists in the development of diabetes, and five publications indicate the development of new-onset diabetes with different antihypertensive agents amongst each other or in comparison to no antihypertensive treatment. The clinical trials show a significant difference in the development of new-onset diabetes. Therapies with diuretics and/or beta-blockers result in a higher incidence of new-onset diabetes. ARB as well as ACE inhibitors have a preventive effect and calcium-channel-blockers show a neutral position regarding the development of new-onset diabetes. Two publications report on economic results. The first one evaluates the cost-effectiveness of ARB alone or in combination with calcium-channel-blockers in comparison to diuretics alone or in combination with beta-blockers. The second publication compares economic outcomes of calcium-channel-blockers and beta-blockers considering the development of new-onset diabetes. Treatment with the ARB candesartan lead to savings in total costs of 549 US-Dollar per patient and in incremental costs of 30,000 US-Dollar per diabetes mellitus avoided. In the second publication, costs to the amount of 18,965 Euro in Great Britain and 13,210 Euro in Sweden are quoted for an avoided event. The treatment with calcium-channel-blockers compared to beta-blockers is proven to be more cost-effective. No publications were identified regarding ethical, social and legal aspects. Discussion: The available meta-analyses allow for a high clinical evidence level. A few studies vary in terms of diabetes definition and study duration. In most of the trials, the incidence of new-onset diabetes is not an endpoint. The evaluation of treatment-induced diabetes mellitus cannot be conducted, due to the lack of sufficient results in the identified literature. The two economic studies do not address all the objectives sufficiently. Ethical, social and legal aspects are discussed but not analysed systematically. Conclusion: Based on these studies, sufficient evidence to confirm the presumption that diuretics and/or beta-blockers promote the development of new-onset diabetes compared to other antihypertensive agents, especially in patients who are predisposed, is presented with this report. Trials reflecting the clinical relevance of treatment-induced diabetes mellitus compared to existing diabetes mellitus regarding cardiovascular outcomes are required. Also health economic evaluations considering the development of new-onset diabetes should be conducted for the different classes of antihypertensive agents

    Abstract Objective Examine cost-driving factors of schizophrenia in Germany for patients prior- and post-switch from an oral antipsychotic therapy to aripiprazole-depot and perform a budget impact analysis (BIA) referring to the context of German health care. Methods A single-armed, retrospective, non-interventional pre-post comparison study with 132 patients to compare the total psychiatric hospitalization rates and the associated costs of both, the treatment with oral antipsychotics and aripiprazole-depot. The BIA was performed to compare both treatment periods with respect to health-related costs. A subsequent univariate sensitivity analysis examined the robustness of the results. Results After switching the treatment to aripiprazole-depot, the total psychiatric hospitalization rates for the 6-month treatment period were significantly (p < 0.001) lower (14%) compared to the hospitalization rates when treated with oral antipsychotics (55.1%). 18.2% of the patients reported to be employed, with 29.2% having work incapacities. The mean number of schizophrenia episodes was 2.58 episodes per patient during the oral-antipsychotic treatment compared to 0.41 episodes per patient during the aripiprazole-depot phase (p < 0.001). The treatment with aripiprazole-depot also significantly reduced the mean number of hospitalizations per patient (0.63 to 0.16, p < 0.001) and the mean number of hospitalized days (27.39 to 5.56, p < 0.001) compared to the oral antipsychotic treatment. Additionally a significant reduction of the mean stay in day-clinics and psychiatric institute ambulances (PIAs) was observed (46.13 days to 7.29 days, p < 0.01). Treatment of a patient suffering from schizophrenia with oral antipsychotics produced costs of 9935.38€ (direct costs: 9498.36 €), while aripiprazole-depot generated costs of 4557.56€ (direct costs: 4449.83 €) per patient for a one-year observation period. This resulted in total costs of 6,517,606,265.43€ for the oral antipsychotic treatment and 2,989,756,603.05€ for aripiprazole-depot treatment from the perspective of the German health care system. The results remained robust during sensitivity analysis, with aripiprazole-depot being the more cost-effective strategy. Conclusions The results suggest that aripiprazole-depot treatment for schizophrenia patients has major potential in terms of cost savings for the German statutory health insurance

    Healthcare Reforms in Germany: Managed Care, An Opportunity?

    No full text
    Increasing healthcare expenditures and other economic pressures mandate fundamental reforms of the healthcare system in Germany. The overall goal is restraint of costs while at the same time maintaining a high standard of medical care. Among all options, managed care represents a potential solution, since it combines financing mechanisms and a care delivery system under the control and direction of a single management entity. A core element of managed care is cost containment through structured guidance of healthcare providers and patients. This has the potential to provide a higher level of control and promote greater transparency in the healthcare system. However, it remains to be seen if it is possible to adapt elements of managed care from other countries to the German healthcare system.Healthcare expenditure, Managed care, Pharmacoeconomics

    Health economic benefits through the use of diagnostic support systems and expert knowledge

    Background!#!Rare diseases are difficult to diagnose. Due to their rarity, heterogeneity, and variability, rare diseases often result not only in extensive diagnostic tests and imaging studies, but also in unnecessary repetitions of examinations, which places a greater overall burden on the healthcare system. Diagnostic decision support systems (DDSS) optimized by rare disease experts and used early by primary care physicians and specialists are able to significantly shorten diagnostic processes. The objective of this study was to evaluate reductions in diagnostic costs incurred in rare disease cases brought about by rapid referral to an expert and diagnostic decision support systems.!##!Methods!#!Retrospectively, diagnostic costs from disease onset to diagnosis were analyzed in 78 patient cases from the outpatient clinic for rare inflammatory systemic diseases at Hannover Medical School. From the onset of the first symptoms, all diagnostic measures related to the disease were taken from the patient files and documented for each day. The basis for the health economic calculations was the Einheitlicher Bewertungsmaßstab (EBM) used in Germany for statutory health insurance, which assigns a fixed flat rate to the various medical services. For 76 cases we also calculated the cost savings that would have been achieved by the diagnosis support system Ada DX applied by an expert.!##!Results!#!The expert was able to achieve significant savings for patients with long courses of disease. On average, the expert needed only 27 % of the total costs incurred in the individual treatment odysseys to make the correct diagnosis. The expert also needed significantly less time and avoided unnecessary examination repetitions. If a DDSS had been applied early in the 76 cases studied, only 51-68 % of the total costs would have incurred and the diagnosis would have been made earlier. Earlier diagnosis would have significantly reduced costs.!##!Conclusion!#!The study showed that significant savings in the diagnostic process of rare diseases can be achieved through rapid referral to an expert and the use of DDSS. Faster diagnosis not only achieves savings, but also enables the right therapy and thus an increase in the quality of life for patients
