Background and aims: The new high sensitivity cardiac Troponin T (cTnThs) assay has recently been introduced in our clinic and ensures higher sensitivity than the fourth-generation cardiac troponin T (cTnT) assay from the same manufacturer (Roche Diagnostics). We determined the diagnostic performance of the cTnThs compared with the cTnT assay in geriatric patients, especially those with non-ST elevation myocardial infarction (NSTEMI). Methods: We retrospectively analysed 253 patients (age 82±8 years; 82 men, 172 women) with diagnoses of suspected NSTEMI admitted to our Department of Geriatric Medicine. Patients were divided into one group of 113 patients using cTnThs, and another of 140 patients using cTnT for diagnosis. Each group included patients at the same months but different years, in either cTnThs or cTnT assays. NSTEMI was diagnosed according to current guidelines. Results: Baseline characteristics were similar in both groups. The proportions of patients with elevated cardiac troponin (cTn) levels significantly increased from 35% in the cTnT group to 76% in the cTnThs group (p<0.001), although no coronary cause for the elevated cTn levels was shown in about two-thirds of these patients. In patients with NSTEMI, 58% in the cTnThs group vs 42% in the cTnT group were diagnosed within 4 hours of the onset of symptoms, whereas 42% in the cTnThs group vs 58% in the cTnT group were diagnosed more than 4 hours later (p=0.018). Conclusions: The prevalence of elevated cTn has more than doubled with the use of cTnThs. However, no coronary cause was found in two-thirds of our geriatric patients, although more NSTEMI patients were diagnosed earlier by cTnThs. ©2012, Editrice Kurtis. Source

Breast Cancer Research and Treatment | Year: 2012

Several factors can influence individual perceptions of the expected benefit of recommended adjuvant treatment for breast cancer. This study investigated differences between patients and physicians with regard to the required efficacy of treatment and the factors influencing patients' and physicians' willingness to accept different therapeutic options. A total of 9,000 questionnaires were distributed to patients with breast cancer, and 6,938 questionnaires were distributed to physicians treating breast cancer patients. The patients were asked for personal information and about their medical history and experiences during treatment. The physicians were asked about personal information and their specialty and work environment. The treatment efficacy required by the two groups was assessed using six virtual cases of breast cancer and the treatment regimens proposed, with specific benefits and side effects. A total of 2,155 patients and 527 physicians responded to the questionnaire (return rates of 23.9 and 7.6 %). Significantly different ratings between patients and physicians with regard to the expected benefit of certain treatment options were observed. The differences were noted not only for chemotherapy but also for antihormonal and antibody treatments. Whereas physicians had a quite realistic view of the expected treatment benefits, the patients' expectations were varied. Approximately onefifth of the patients were willing to accept treatment regimens even with marginal anticipated benefits, whereas onethird required unrealistic treatment benefits. Several influencing factors that were significantly associated with the quality rating of treatment regimens in the groups of breast cancer patients and physicians were also identified. In contrast to physicians, many breast cancer patients required treatment benefits beyond what was realistically possible, although a large group of patients were also satisfied with minimal benefits. Individual factors were also identified in both groups that significantly influence thresholds for accepting adjuvant treatment, independently of risk estimates and therapy guidelines. © Springer Science+Business Media, LLC. 2012.

BMC Medical Education | Year: 2014

Background: Simulation-based-training (SBT) in the education of health professionals is discussed as an effective alternative for knowledge and skills enhancement as well as for the establishment of a secure learning environment, for learners and patients. In the Anglo-American region, SBT and simulation and training centers (STC) are numbered as standard for medical training. In German-speaking Central Europe, priority is still given to the establishment of SBT and STC. The purpose of this study was (i) to survey the status quo relating to the existence and facilities of simulation and training centers at medical universities in German-speaking Central Europe and (ii) the evaluation of training methods, especially in the area of emergency medicine skills. Methods: All public and private medical universities or medical faculties in Germany (36), Austria (4) and German-speaking Switzerland (3) were interviewed. In the survey, information regarding the existence and facilities of STCs and information with regards to the use of SBT in the area of emergency medicine was requested. The questions were partly posed in a closed-ended-, in an open-ended- and in a multiple choice format (with the possibility of selecting more than one answer). Results: Of a total of 43 contacted medical universities/medical faculties, 40 ultimately participated in the survey. As decisive for the establishment of a STC the potential to improve the clinical-practical training and the demand by students were listed. Obligatory training in a STC during the first and sixth academic year was confirmed only by 12 institutions, before the first invasive procedure on patients by 17 institutions. 13 institutions confirmed the use of the STC for the further training of physicians and care-staff. Training for the acute care and emergency medicine skills in the field of pediatrics, for the most part, occurs decentralized. Conclusions: New methods in medical training have reached German-speaking Central Europe, but the simulation and training centers vary in size, equipment or regarding their integration into the obligatory curriculum as much as the number and variety of the offering to be trained voluntarily or on an obligatory basis. © 2014 Fandler et al.; licensee BioMed Central Ltd.

Breast Cancer Research and Treatment | Year: 2013

Treatment decisions in oncology are based on a balance between the efficacy of therapy and its side effects. Patients with metastases and patients with a limited prognosis are a particular challenge, since communication about the disease situation and the expected therapeutic benefit is difficult not only for patients, but also for physicians. The aim of this study was therefore to compare the benefits expected of therapy by patients and physicians. Questionnaires were sent to 9,000 breast cancer patients and to 6,938 physicians. The questionnaires described 10 cases of breast cancer in the metastatic setting. The patients and physicians were asked to state the treatment benefit they would require to decide for the therapy options chemotherapy, endocrine therapy, antibody therapy, radiotherapy, and bisphosphonates. Additionally, the participants provided data on patient and physician characteristics. Expected treatment benefits were compared between patients and physicians, and influencing factors that modified the expected benefit were identified. Patients expected much greater benefits from the therapies offered than the physicians. For all treatment modalities, about 50 % or more of patients expected more than a 12-month increase in overall survival from all therapies. Among the doctors, this proportion ranged from 7 to 30 %. Among patients, previous experience of side effects and having young children in the family were the strongest influencing factors. Among the doctors, age and level of education had a strong influence on the expected prognostic improvement to indicate a therapy option. As expectations of treatment differ greatly between patients and doctors, a structured approach to solving this conflict is required. There appear to be some indicators that might help address the problem, such as the physicians' level of training and experience and the patients' specific social circumstances. © 2013 Springer Science+Business Media New York.

Objectives: To determine if an algorithm implementing a serial high-sensitive cardiac troponin T (hs-cTnT) measurement at presentation (0h) and at 3 hours after presentation (3h) is helpful for early diagnosis of non-ST-elevation myocardial infarction (NSTEMI) in older patients. Design: Prospective observational cohort study. Setting: An emergency department (ED) of a city hospital covering a population of approximately 1 million in Germany. Participants: A total of 332 consecutive unselected patients were recruited, of whom 25 had one or more of the prespecified exclusion criteria and 1 had a missing hs-cTnT at 3h, resulting in a final population of 306 patients. Measurements: In addition to clinical examination, hs-cTnT was measured at 0h and 3h. The final diagnosis of NSTEMI was adjudicated by two independent consultants and an algorithm for rule-in and rule-out of NSTEMI was developed using classification and regression tree analysis. All patients were followed-up for cardiovascular outcome within 12 months. Results: Among 306 patients (mean age 81 ± 6 years), 38 (12%) patients had NSTEMI. Accuracy to diagnose NSTEMI was significantly higher for hs-cTnT measurements at 3h versus 0h (area under the receiver operating characteristic curve [AUC] 0.88 vs. 0.82, P = .0038) and for absolute versus relative hs-cTnT delta changes (AUC 0.89 versus 0.69, P < .001). A diagnostic algorithm using hs-cTnT values at presentation and absolute delta changes values ruled-in NSTEMI in 23% and ruled-out NSTEMI in 35% of patients. For patients neither fulfilling the rule-in nor the rule-out criteria, an observational zone was established. Cumulative 1-year survival was 79.4%, 88.5%, and 99.1% in patients classified as rule-in, observational zone, and rule-out, respectively. Conclusion: In older patients, serial hs-cTnT measurements and absolute delta-changes at 3h were valuable for early diagnosis of NSTEMI. An algorithm ruled-in NSTEMI in one quarter of patients with high risk and ruled-out NSTEMI in one-third with low risk. © 2013 American Medical Directors Association, Inc. Source
