Konsensusstatement „Praktische Fertigkeiten im Medizinstudium“ - ein Positionspapier des GMA-Ausschusses für praktische Fertigkeiten

Einleitung: Angestoßen durch die Änderung der Approbationsordnung haben die berufspraktischen Kompetenzen in Deutschland eine höhere Priorität erhalten und werden in den medizinischen Fakultäten deswegen vermehrt vermittelt. Dadurch entstand die Notwendigkeit, den Prozess mehr und mehr zu standardisieren. Auf Initiative der deutschsprachigen Skills Labs wurde der GMA-Ausschuss für praktische Fertigkeiten gegründet, der einen kompetenzbasierten Lernzielkatalog entwickelte, dessen Entstehung und Struktur hier beschrieben wird. Ziel des Kataloges ist es, die praktischen Fertigkeiten im Medizinstudium zu definieren und damit den Fakultäten eine rationale Planungsgrundlage für die zur Vermittlung praktischer Fertigkeiten notwendigen Ressourcen zu geben. Methodik: Aufbauend auf schon vorhandenen deutschsprachigen Lernzielkatalogen wurde mittels einem mehrfach iterativem Kondensationsprozesses, der der Erarbeitung von S1-Leitlinien entspricht, vorgegangen, um eine breite fachliche und politische Abstützung zu erhalten. Ergebnisse: Es wurden 289 verschiedene praktische Lernziele identifiziert, die zwölf verschiedenen Organsystemen, drei Grenzbereichen zu anderen Kompetenzbereichen und einem Bereich mit organsystemübergreifenden Fertigkeiten zugeordnet. Sie wurden drei verschiedenen zeitlichen und drei verschiedenen Tiefendimensionen zugeordnet und mit dem Schweizer und dem Österreichischem Pendant abgeglichen. Diskussion: Das vorliegende Konsensusstatement kann den deutschen Fakultäten eine Grundlage zur Planung der Vermittlung praktischer Fertigkeiten bieten und bildet einen wichtigen Schritt zu einem nationalen Standard medizinischer Lernziele. Blick in die Zukunft: Das Konsensusstatement soll einen formativen Effekt auf die medizinischen Fakultäten haben, ihre praktischen Unterrichtsinhalte entsprechend zu vermitteln und die Ressourcen danach zu planen.

[Analgesia for pediatric patients. Standards and special aspects]

In this paper we describe the assessment and medical treatment of pain in children according to the concept of the Centre of Pediatrics and Adolescent Medicine at the university of Freiburg, Germany. Opiate therapy in children as well as novel data about the association of paracetamol (acetaminophen) and wheezing/asthma bronchiale in children are discussed. Special aspects of analgesia for painful procedures and a nitrous oxide/oxygen mixture which has been recently introduced in Germany are described. The second part of the paper presents results of our prospective study about continuous infusion of fentanyl and midazolam in a fixed combination in 19 critically ill patients with a median age of 46 months, 40% of these patients had an ARDS. The mortality rate was 21%. A median dose of fentanyl of 3.9 microg/kg/h (midazolam 0.26 mg/kg/h) was infused. The fentanyl serum level (median 4.2 ng/ml, range 1.7-17.8 ng/ml) correlated significantly with the administered dose while the midazolam serum levels (median 911 ng/ml, range 234-4 651 ng/ml) correlated neither with the administered dose nor with any of the analysed parameters. Conclusion: A standard protocol for the assessment and treatment of pain should be established in every pediatric hospital. The data about the association of asthma bronchiale and paracetamol cannot be interpreted conclusively, but show that even for well known substances clinical trials may lead to new awareness. The study data about continuous infusion of fentanyl and midazolam show a good correlation of the fentanyl application to serum levels, while midazolam appears to be not the optimal substance for continuous sedation in this setting.

[Burden and need for psychosocial intervention of glioblastoma patients]

Glioblastoma patients should be provided with a professional health care system that helps reduce their psychosocial burden. The aim of this study was to identify patients in need of psychosocial intervention. In addition, it was examined whether physicians' assessments adequately address the burden patients are under and their need for intervention. During their visit to one of two neurosurgery outpatient departments, n = 49 glioblastoma patients filled out the short version of the Hornheider questionnaire (HFK). Consulting physicians also rated their patients' burdens in a specially adapted version of the questionnaire (HFK-F). The results of the psychometric evaluation with both instruments were satisfactory. The majority of the patients (76 %) were identified as in need of psychosocial intervention. All of them were correctly categorized with the physicians' ratings. Physicians overestimated some aspects of the patients' burden, particularly in regard to their problems with relaxing and fear of living with the illness. The patients' ratings concerning the quality of the information physicians provided and their overall state of health only corresponded with the physicians' ratings in roughly half of the cases.

Retrospective adjustment of self-assessed medical competencies - noteworthy in the evaluation of postgraduate practical training courses

The efficacy of postgraduate practical training courses is frequently evaluated by self-assessment instruments. The present study analyses the effect of a basic course in laparoscopic surgery on self-assessed medical competencies.

[Alban Köhler (1874-1947): Inventor of grid therapy]

Grid (or sieve) therapy ("Gitter-" oder "Siebtherapie"), spatially fractionated kilo- and megavolt X-ray therapy, was invented in 1909 by Alban Köhler, a radiologist in Wiesbaden, Germany. He tested it on several patients before 1913 using approximately 60-70kV Hittorf-Crookes tubes. Köhler pushed the X-ray tube's lead-shielded housing against a stiff grid of 1 mm-square iron wires woven 3.0-3.5mm on center, taped tightly to the skin over a thin chamois. Numerous islets unshielded by iron in the pressure-blanched skin were irradiated with up to about 6 erythema doses (ED). The skin was then thoroughly cleansed, disinfected, and bandaged; delayed punctate necrosis healed in several weeks. Although grid therapy was disparaged or ignored until the 1930s, it has been used successfully since then to shrink bulky malignancies. Also, advanced cancers in rats and mice have been mitigated or ablated using Köhler's concept since the early 1990s by unidirectional or stereotactic exposure to an array of nearly parallel microplanar (25-75μm-wide) beams of very intense, moderately hard (median energy approximately 100 keV) synchrotron-generated X rays spaced 0.1-0.4mm on center. Such beams maintain sharp edges at high doses well beneath the skin yet confer little toxicity. They could palliate some otherwise intractable malignancies, perhaps in young children too, with tolerable sequelae. There are plans for such studies in larger animals.

[Spontaneous bacterial peritonitis]

Spontaneous bacterial peritonitis (SBP) is the most frequent infection in patients with cirrhosis during hospitalization and is associated with high acute and long-term mortality. Diagnosis is made by paracentesis with determination of neutrophil count in ascitic fluid. Empirical antibiotic therapy must be initiated immediately. The choice of drug is dependent on prior therapies. Liver transplantation has to be considered in the absence of contra-indications. Prophylaxis of SBP is indicated in patients with ascites and gastrointestinal hemorrhage, and in patients after SBP. Primary prophylaxis should be considered in high-risk patients with cirrhosis and ascites. The development of resistance to antibiotic drugs is a relevant side-effect.
