Percutaneous coronary intervention with optimal medical therapy vs. optimal medical therapy alone for patients with stable angina pectoris.
Stable Angina Pectoris (AP) is a main syndrome of chronic coronary artery disease (CAD), a disease with enormous epidemiological and health economic relevance. Medical therapy and percutaneous coronary interventions (PCI) are the most important methods used in the treatment of chronic CAD. ⋯ From a medical point of view the routine use of PCI in addition to the optimal medicinal therapy in patients with stable AP can be recommended for the reduction of the proportion of patients with AP attacks after one year and after three years (recommendation degree weak). Otherwise, PCI is to be performed in patients with refractory or progressing AP despite of optimal medical therapy use; in this case PCI is expected to be applied in 27% to 30% of patients in five years. From the health economic view the routine use of PCI in addition to an optimal medical therapy in patients with stable AP cannot be recommended. No special considerations can be made concerning special ethical, social or legal aspects in the routine use of PCI in addition to optimal medical therapy in patients with stable AP.

There is no consistent definition of burnout. It is neither a defined diagnosis in ICD-10 nor in DSM-IV. Yet it is diagnosed by office-based doctors and clinicians. Mainly due to reimbursement reasons, diagnoses like depression are used instead of burnout diagnoses. Therefore burnout has a very high individual, social and economic impact. ⋯ The authors conclude, that (1) further research, particularly high-quality studies are needed, to broaden the understanding of the burnout syndrome. Equally (2) a definition of the burnout syndrome has to be found which goes beyond the published understanding of burnout and is based on common scientific consent. Furthermore, there is a need (3) for finding a standardized, international accepted and valid procedure for the differentiated diagnostics of burnout and for (4) developing a third party assessment tool for the diagnosis of burnout. Finally, (5) the economic effects and implication of burnout diagnostics on the economy, the health insurances and the patients have to be analysed.

The impact of microsurgery, stereotactic radiosurgery and radiotherapy in the treatment of meningiomas depending on different localizations.
Meningiomas are the most common benign intracranial neoplasms with a slow growth presented as the intracranial lesion. These tumors are without any symptoms for a long time. At the time of diagnosis it is frequently an asymptomatic tumor. In that case the therapist may well suggest a wait-and-see strategy. The therapy of meningiomas focuses firstly on the microsurgical treatment. Volume reduction can be achieved immediately after treatment. Stereotactic radiosurgery is an important non-invasive treatment option for recurrent tumors or meningiomas with partial resection. The technical equipment for the stereotactic radiosurgery is a cost intensive investment. In this context the high precision of the intervention, presented as a low invasiveness of the treatment, is an important factor. The aim of this assessment is to identify the chances and limitations of the diverse treatment options and to estimate their outcome for different localisations of meningiomas. ⋯ Due to the strong dependencies between the results from surgical therapy and the localisation of the tumor, it is only possible to derive recommendations on whether or not to perform the surgical therapy with respect to the localisation of the tumor. Only for patients with tumors with a spinal localisation or WHO Grade I meningiomas with a cortical localisation, primary treatment with by means of microsurgery can be suggested. For all other localisations of the tumor, alternative treatment by radiosurgery should be discussed. From the literature identified, a clear recommendation of one or the other therapy however can not be deduced. Thus, there is a strong need for randomised clinical trials or prospective or contrasting cohort studies, which compare rigorously microsurgery with radiosurgery concerning different localisations of tumors.

Invasive home mechanical ventilation, mainly focused on neuromuscular disorders.
Invasive home mechanical ventilation is used for patients with chronic respiratory insufficiency. This elaborate and technology-dependent ventilation is carried out via an artificial airway (tracheal cannula) to the trachea. Exact numbers about the incidence of home mechanical ventilation are not available. Patients with neuromuscular diseases represent a large portion of it. ⋯ Positive effects of the invasive mechanical ventilation (overall survival and symptomatic) are highly probable based on the analysed literature, although with a low level of evidence. An establishment of a home ventilation registry and health care research to ascertain valid data to improve outpatient structures is necessary. Gathering specific German data is needed to adequately depict the national concepts of provision and reimbursement. A differentiation of the cost structure according to the type of chosen outpatient care is currently not possible. There is no existing literature concerning the difference of life quality depending on the chosen outpatient care (homecare, assisted living, or in a nursing home specialised in invasive home ventilation). Further research is required. For a so called participative decision - made by the patient after intense counselling - an early and honest patient education pro respectively contra invasive mechanical ventilation is needed. Besides the long term survival, the quality of life and individual, social and religious aspects have also to be considered.

Medical and health economic evaluation of prevention- and control measures related to MRSA infections or -colonisations at hospitals.
Methicillin-resistant Staphylococcus aureus (MRSA) are dangerous agents of nosocomial infections. In 2007 the prevalence of MRSA is 20.3% in Germany (Oxacilline-resistance according to EUCAST-criteria [EUCAST = European Committee on Antimicrobial Susceptibility Testing]). ⋯ It is evident that selective screening programs of risk patients considering the particular MRSA-prevalence are of use. The application of rapid tests seems to be only recommendable for risk patients and a high MRSA-prevalence. The improvement of the compliance of hand hygiene should be the basis of any prevention strategy. Training of staff members (with feedback mechanisms) is effective to improve compliance and to optimise the use of antibiotics. Antibiotic management programs are effective as well. Obviously multimodal approaches can lead to overadditive effects. Therefore the catalogue of preventive and control measurements has to be further evaluated. Good cost-efficacy studies are missing in Germany. The psychosocial effects of MRSA-infections are not researched in Germany. There is only punctual information on the risk management of hospitals.
