[Various scenarios for billing and remuneration of preoperative management of iron deficiency anemia in the German healthcare system]. / Verschiedene Szenarien zu Abrechnung und Kostenerstattung eines präoperativen Managements der Eisenmangelanämie im deutschen Gesundheitssystem.

More than 30% of all patients undergoing surgery suffer from preoperative anemia. Iron deficiency anemia is the most common type of anemia. The diagnostics and treatment of iron deficiency anemia can be carried out before patients undergo surgery as an alternative to blood transfusion and is an interdisciplinary task. This article gives an overview of various billing modalities and payment arrangements for management of preoperative anemia in the German healthcare system.

[Formal prescribing errors are substantially reduced in electronic prescribing and after teaching sessions]. / Formale Fehler bei der Rezeptschreibung sind bei Nutzung elektronischer Verordnung und Schulung erheblich reduziert.

INTRODUCTION: Prescription forms enable the communication between physicians and pharmacists. Hence, incorrectly issued prescriptions may result in delay of health-care delivery, additional workload, and potentially adverse patient outcomes. We aimed to evaluate the formal prescription quality in our outpatient clinics (OC) before and after performing teaching sessions and using an electronic prescription system to replace handwritten prescriptions. METHODS: All OCs of a university hospital were offered a short teaching session on how to issue prescriptions correctly and how to use the electronic prescription system. During four weeks before and after the teaching, we anonymously collected all prescriptions of the OCs in 20 surrounding community pharmacies and assessed whether they were error-free, required an intervention by the pharmacist, additional clarification by the OC, or had to be reissued. RESULTS: After the intervention, the absolute fraction of formally error-free prescriptions increased by 12.9% from 52.9% (516/976) to 65.8% (713/1084, p < 0.001; d = 12,9% 95% confidence interval [8,7%; 17,1%]). Largest improvements were seen in prescriptions requiring clarification by the OC (224/976 prescriptions at baseline versus 93/1084 post-intervention, p < 0.001). The fraction of electronic prescriptions increased from 34.9% (341/976) to 46.9% (509/1084, p < 0.001, d = 12,0% 95% confidence interval [7,8%; 16,2%]) with electronic prescriptions consistently being of higher formal quality than handwritten prescriptions. CONCLUSION: After increased use of electronic prescribing and teaching courses, formal prescription quality was significantly improved.

[Patient safety in anesthesiology : Multimodal strategies for perioperative care]. / Patientensicherheit in der Anästhesie : Multimodale Strategien für die perioperative Versorgung.

The concept of patient safety is more of a presence in modern day medicine than ever before. All measures and processes aiming at preempting and preventing critical incidents and accidents in patient care are collectively grouped under this concept. With the Declaration of Helsinki in 2010 modern anesthesiology has undertaken a fundamental role in the clinical implementation and perioperative clinicians are confronted with a multitude of theories, models, methods and tools targeted at improving or facilitating optimized patient safety. One of the biggest challenges lies in their synergistic combination to create a functioning concept for perioperative risk management while also incorporating individual strengths and weaknesses. The aim of the present paper is to provide a structured overview of the various components presently available for increasing perioperative patient safety.

Treatment cost of invasive fungal disease (Ifd) in patients with acute myelogenous leukaemia (Aml) or myelodysplastic syndrome (Mds) in German hospitals.

Invasive fungal disease (IFD) causes increasing morbidity and mortality in haematological cancer patients. Reliable cost data for treating IFD in German hospitals is not available. Objective of the study was to determine the institutional cost of treating the IFD. Data were obtained by retrospective chart review in German hospitals. Patients had either newly diagnosed or relapsed acute myeloid leukaemia (AML) or myelodysplastic syndrome (MDS). Direct medical cost was calculated from hospital provider's perspective. A total of 108 patients were enrolled at 5 tertiary care hospitals, 36 IFD patients and 72 controls. The vast majority of IFD patients (74%) were diagnosed with invasive aspergillosis. On average, the hospital stay for IFD patients was 12 days longer than in control patients. All patients in the IFD group and 89% of patients in the control group received antifungal drugs. Mean direct costs per patient were €51,517 in the IFD group and €30,454 in the control group. Incremental costs of €21,063 were dominated by cost for antifungal drugs (36%), hospital stay (32%) and blood products (23%). From the perspective of hospitals in Germany the economic burden of IFD in patients with AML or MDS is substantial. Therefore, prevention of IFD is necessary with respect to both clinical and economic reasons.

[From basic research to the clinic. Regulations for preclinical and clinical studies with stem cells]. / Von der Grundlagenforschung in die Klinik. Regulative Anforderungen an präklinische und klinische Studien mit Stammzellen.

The discovery of human embryonic stem cells at the end of 1998 had a strong influence on the development of stem cell research and led to controversial discussions. The first therapeutic application of adult blood stem cells began after their discovery in 1963 and was accepted as an authorized therapy in the early 1980s. The way from basic research to therapeutic use needed about 20 years and was also discussed in a controversial way similar to the discussions of today. The regulatory environment at that time, however, allowed a quick translation of the results from basic research to the clinic. Today many new stem cell therapies for a multitude of diseases are under development. Their clinical realization is regulated by the AMG (Arzneimittelgesetz). For nonclinical research as well as for clinical research, specific regulations are enacted to guarantee a structured and safe launch. Time, know how and money for planning, request for authorization and conduction of a clinical trial should not be underestimated. For clinical application of stem cell products authorization by the proper authorities is mandatory.

Stable mixed chimerism after T cell-depleted allogeneic hematopoietic stem cell transplantation using conditioning with low-dose total body irradiation and fludarabine.

Although reduced intensity conditioning (RIC) before allografting is associated with low treatment-related morbidity and mortality, graft-versus-host disease (GVHD) remains a significant complication of hematopoietic stem cell transplantation (HSCT). T cell depletion (TCD) has been successfully used in conventional allotransplantation to reduce the incidence of GVHD, but was associated with an increased rate of engraftment failure. In a small cohort of six patients at high risk of developing GVHD we have determined whether sustained engraftment could be achieved using reduced intensity conditioning and T cell depletion in combination. All patients engrafted and 5/6 developed high levels (i.e. > or =95%) of donor chimerism, even though mismatched related or matched unrelated donors were used. Only one patient developed acute GVHD, as he received donor lymphocyte infusions (DLI) for relapse. In summary, TCD might be a useful prophylactic tool in RIC allogeneic HSCT. Although TCD after RIC might be associated with high relapse rate, as 5/6 patients are not in remission, this combined strategy might be appropriate for patients with less aggressive malignant or non-malignant diseases in which high transplant-related morbidity and mortality is not acceptable.
