Background: The purpose of this pilot study was to create a valid and reliable set of assessment questions for examining Evidence-based Dentistry (EbD) knowledge. For this reason, we adapted and validated for dental students the Berlin Questionnaire (BQ), which assesses Evidence-based Medicine (EbM) abilities.
Methods: The Berlin Questionnaire was validated with medical residents. We adapted it for use in a dentistry setting. An expert panel reviewed the adapted BQ for content validity. A cross-sectional cohort representing four training levels (EbD-novice dental students, EbD-trained dental students, dentists, and EbM−/EbD-expert faculty) completed the questionnaire. A total of 140 participants comprised the validation set. Internal reliability, item difficulty and item discrimination were assessed. Construct validity was assessed by comparing the mean total scores of students to faculty and comparing proportions of students and faculty who passed each item.
Results: Among the 133 participants (52 EbD-novice dental students, 53 EbD-trained dental students, 12 dentists, and 16 EbM-/ EbD-expert faculty), a statistically significant (p < 0.001) difference was evident in the total score corresponding to the training level. The total score reliability and psychometric properties of items modified for discipline-specific content were acceptable. Cronbach’s alpha was 0.648.
Conclusion: The adapted Berlin Questionnaire is a reliable and valid instrument to assess competence in Evidence-based Dentistry in dental students. Future research will focus on refining the instrument further.
Hintergrund: Bislang fehlen umfassende Daten zu Evaluationspraktiken und Leistungsorientierter Mittelvergabe (LOM) in der Lehre für die deutschen medizinischen Fakultäten. Vor diesem Hintergrund haben sich die Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften e.V. (AWMF) und der Medizinische Fakultätentag (MFT) das gemeinsame Ziel gesetzt, die Praxis der Evaluationen und LOM in der Lehre (LOM-Lehre) an den medizinischen Fakultäten in Deutschland zu analysieren.
Methoden: Die Datenerhebung erfolgte mittels Fragebogen, der an alle medizinischen Fakultäten in Deutschland gesandt wurde.
Ergebnisse: An der Befragung nahmen 30 Fakultäten mit insgesamt 33 Studiengängen teil (Rücklauf: 83%). Die an den Fakultäten eingesetzten Erhebungsinstrumente erfassen vorrangig strukturelle und prozedurale Aspekte sowie einen Gesamteindruck der Lehre. Zwischen den Fakultäten herrscht bezüglich der verwendeten Instrumente eine recht hohe Heterogenität. Teilweise bleibt unklar, inwiefern die Erhebungsinstrumente internationalen Qualitätsstandards genügen. Die finanzielle Honorierung der Lehre erfolgt überwiegend im Rahmen der Grundausstattung bzw. nach Kriterien der Lehr-Quantität. Qualitätsbasierte Mittelzuweisung spielt eine eher untergeordnete Rolle.
Schlussfolgerung: Eine möglichst bundesweite Konsentierung eines Leitbilds guter Lehre sowie die Identifikation bzw. Entwicklung valider und reliabler Erhebungsinstrumente in deutschlandweiter Zusammenarbeit scheint erstrebenswert und würde eine Weiterentwicklung der gültigen LOM-Lehre darstellen.
Background: In Germany, patients suffering from life-limiting conditions are eligible for specialized outpatient palliative care (SOPC). Evaluation of the quality of this service lacks currently integration of patient-relevant outcomes. There is also no scientific consensus how to prove quality of care in the special context of SOPC adequately. Existing quality reports are primarily based on descriptive structural data which do not allow for estimation of process quality or result quality. The ELSAH study ("Evaluation of Specialized Outpatient Palliative Care in the German state of Hesse") aims to choose - or, if necessary, to adopt - to evaluate and to implement a suit of measures to assess, evaluate and monitor the quality of specialized, home-based palliative care.
Methods: All 22 SOPC teams providing their services in the state of Hesse, Germany, participate in the ELSAH study. The study is divided in two phases: a preparation phase and a main study phase. Based on the findings of the preparation phase we have chosen a preliminary set of instruments including the Integrated Palliative Outcome Scale, Views on Care, Zarit Burden Interview, Phase of Illness, Goal Attainment Scaling, Eastern Cooperative Oncology Group Performance Status, Consumer Quality Indices Palliative Care and Sense of Security in Care. During the main study phase, we will use a mixed-methods approach to evaluate the instruments’ psychometric properties (reliability, validity, feasibility and practicability), to identify barriers, facilitators and limitations of their routine use and to explore how their use affects the care within the SOPC setting.
Discussion: At the end of this study, an outcome- and patient-centered, validated measurement approach should be provided, adapted for standardized evaluations in SOPC across patient groups, palliative care services and regions nationwide. The standardized application of instruments should allow for making valid statements and comparisons of health care quality in SOPC based on process- and outcome-evaluation rather than relying on structural data only. Moreover, the instruments might directly influence the care of patients in palliative situations.
Trial registration: German Clinical Trials Register (DRKS-ID: DRKS00012421).
Background: The aim of this study was to investigate the acceptance and assessment of work shadowing carried out by students and dentists in dental practices. Furthermore, the extent to which students perceive an improvement in their specialised, communication and social competencies, was to be examined.
Methods: 61 dental students in their clinical semesters at a German university participated in work shadowing placements at 27 different general dental practices. Before beginning, they received checklists of various competencies that they self-assessed using school grades (from 1 = "very good", to 6 = "failed"), which they also repeated after completion. The dentists supplemented this with their external assessments. In addition, the students were requested to fill out a 54-item questionnaire and compose a freely-structured report after the work shadowing; the dentists filled out a questionnaire containing 16 items. The statistical analysis was carried out by means of the Friedman Test, including a post-hoc test (Bonferroni-Holm correction).
Results: The analysis showed a significant overall improvement in the students’ self-assessed competencies by 0.71* ± 0.43 grades. With an average of 0.33* ± 0.36, the dentists’ external assessment proved significantly higher than the self-assessment. The greatest improvements were perceived by the students in the areas of accounting (1.17* ± 0.77), practice organisation (1.05* ± 0.61) and dentist’s discussions (0.94* ±0.80) [*p < 0.05]. The students confirmed experiencing an expansion of knowledge, an improvement in their communication skills and indicated a high degree of satisfaction in regard to the dentists (school grade 1.58 ± 0.93). A maximum amount of satisfaction towards the work shadow students was demonstrated by the dentists, and this form of teaching was assessed with a school grade of 1.69 ± 0.89.
Conclusion: Both students and dental practitioners demonstrated a high level of satisfaction in regard to the work shadowing. The students felt their knowledge had increased, viewed the dentists as motivating role models and acknowledged a significant improvement in their specialised, communication and social competencies. Work shadowing in dental teaching practices presents a sensible addition to academic teaching at a university.
Background: Lectures remain an important teaching method to present and structure knowledge to many students concurrently. Adequate measures are necessary to maintain the quality of the lectures. The aim of this study was to determine the impact on the lecture quality using written structured feedback and to compare the ratings of surgical lectures between students and surgical peers.
Methods: Prospective analysis of two consecutive surgical lecture series for undergraduate students at Goethe-University Medical School was performed before and after evaluation of the lecturers via independent written feedback from trained undergraduate students and surgeons. The 22-item feedback instrument covered three areas of performance: content, visualization, and delivery. Additional suggestions for improvement were provided from
both students and surgical peers who anonymously attended the lectures. The lecturers, experienced surgeons, as well as the student and peer raters were blinded in terms of the aim and content of the study. Their response to the feedback was collected using a web-based 13-item questionnaire. The Kendall’s-W coefficient was computed to calculate inter-rater reliability (IRR). Differences between ratings before and after feedback were analyzed using Student’s t-test for dependent samples. The Kolmogorov-Smirnov-test was used for independent samples.
Results: A total of 22 lectures from a possible 32 given by 13 lecturers were included and analyzed by at least three surgeons and two students. There were significant improvements in overall score as well as in the details of 9 of the 13 items were found. The average inter-rater reliability was 0.71. There were no differences in the ratings as a function of the rater’s level of expertise (peers vs. students). We found that 13/23 lecturers (56.5%) answered the questionnaire, and 92% strongly agreed that the written feedback was useful. 76.9% of the lecturers revised their lecture based on the written feedback requiring on average 112.5 min (range from 20 to 300 min).
Conclusions: Overall, this study indicates that structured written feedback provided by trained peers and students that is subsequently discussed by the lecturers concerned is a highly effective and efficient method to improve aspects of lecturing. We anticipate that structured written feedback by trained students that is discussed by the lecturers concerned will improve lecturing.

Background: There is general consensus that the organizational and administrative aspects of academic study programs exert an important influence on teaching and learning. Despite this, no comprehensive framework currently exists to describe the conditions that affect the quality of teaching and learning in medical education. The aim of this paper is to systematically and comprehensively identify these factors to offer academic administrators and decision makers interested in improving teaching a theory-based and, to an extent, empirically founded framework on the basis of which improvements in teaching quality can be identified and implemented.
Method: Primarily, the issue was addressed by combining a theory-driven deductive approach with an experience based, “best evidence” one during the course of two workshops held by the GMA Committee on Personnel and Organizational Development in Academic Teaching (POiL) in Munich (2013) and Frankfurt (2014). Two models describing the conditions relevant to teaching and learning (Euler/Hahn and Rindermann) were critically appraised and synthesized into a new third model. Practical examples of teaching strategies that promote or hinder learning were compiled and added to the categories of this model and, to the extent possible, supported with empirical evidence.
Based on this, a checklist with recommendations for optimizing general academic conditions was formulated.
Results: The Frankfurt Model of conditions to ensure Quality in Teaching and Learning covers six categories: organizational structure/medical school culture, regulatory frameworks, curricular requirements, time constraints, material and personnel resources, and qualification of teaching staff. These categories have been supplemented by the interests, motives and abilities of the actual teachers and students in this particular setting. The categories of this model provide the structure for a checklist in which recommendations for optimizing teaching are given.
Conclusions: The checklist derived from the Frankfurt Model for ensuring quality in teaching and learning can be used for quality assurance and to improve the conditions under which teaching and learning take place in medical schools.
Einleitung: Die vorliegende Studie beschreibt unser Online-Lehrmaterial Humangenetik im Zusammenhang mit dem k-MED-Projekt (Knowledge in Medical Education) an der Philipps-Universität Marburg. Es besteht aus fünf E-Learning-Modulen: Zytogenetik, Chromosomenstörungen, Formalgenetik, Grundlagen der molekularen Diagnostik sowie Kongenitale Abnormitäten und Fehlbildungssyndrome. Diese E-Module sollen ein einheitliches Wissensniveau der Studierenden gewährleisten und die Dozenten in der Präsenzlehre entlasten. Methoden: Die fünf E-Learning-Module Humangenetik wurden auf freiwilliger Basis einer großen Personengruppe von ca. 3300 Studierenden am Fachbereich Humanmedizin der Universität Marburg über eine Dauer von vier Jahren angeboten. Die Teilnehmer bestanden aus Naturwissenschaftlern (Humanbiologie) im 5. Fachsemester und Studierenden der Humanmedizin, die sich entweder in der Vorklinik (1. Semester) oder im klinischen Studienabschnitt (7./8. Semester) befanden. Von diesen wurden Daten zur Akzeptanz in Form von Usertrackingdaten und klausur-begleitenden Fragebögen erhoben. Ergebnisse und Schlussfolgerung: Die Evaluation zeigte eine breite Akzeptanz unserer Lehrmodule über einen Zeitraum von acht Semestern. Obwohl das Angebot freiwillig ist, werden die Online-Kurse Humangenetik konstant oder sogar in zunehmendem Maße zwischen Wintersemester 2005/06 und Sommersemester 2009 genutzt. Fazit: Unser E-Learning-Modell Humangenetik wird von Studierenden aus unterschiedlichen Semestern und Studiengängen am Fachbereich Humanmedizin gut angenommen und genutzt. Bei sorgfältiger Pflege der Online-Kurse steigern moderate Anpassungen sowohl Akzeptanz als auch Benutzungshäufigkeit in signifikanter Weise. Die Anwendung der E-Learning Module erscheint uns auch in der Ausbildung von MTAs oder Pflegekräften sinnvoll, um ein ausreichendes Grundwissen in Humangenetik zu gewährleisten.

Die Vermittlung der Zusammenhänge zwischen psychologischen Funktionen und körperlichen Veränderungen sowie deren Relevanz für die Entstehung und Aufrechterhaltung von Krankheiten stellt ein zentrales Ziel der Ausbildung in Medizinischer Psychologie dar. Zur Veranschaulichung dieser Zusammenhänge führten wir ein Psychophysiologie-Praktikum im ersten vorklinischen Semester ein. Die Studierenden führten in Vierergruppen mit Hilfe ausführlicher schriftlicher Instruktionen jeweils ca. 30 Minuten andauernde praktische Übungen durch, die die folgenden Themen behandelten: (1) Stress (abhängige Variable: Herzrate), (2) "Lügendetektor" (abhängige Variable: Hautleitwertsreaktionen), (3) Biofeedback (abhängige Variable: Hauttemperatur) und (4) Elektroenzephalogramm (abhängige Variable: Amplituden der vier klassischen Frequenzbänder). Die praktischen Übungen wurden durch theoretische Gruppenarbeiten und einen Termin zur Zusammenfassung der Ergebnisse der Übungen ergänzt. Die studentische Evaluation des Praktikums war durchweg positiv. So wurde das Praktikum als Bereicherung des Kurses angesehen, und der selbstbeurteilte Kenntnisstand auf dem Gebiet der Psychophysiologie zeigte eine signifikante Verbesserung. Diese Ergebnisse sowie unsere Eindrücke während des Praktikums bekräftigten unseren Entschluss, ein Psychophysiologie-Praktikum als Teil des Kurses der Medizinischen Psychologie und Medizinischen Soziologie fest zu etablieren.
E-Learning soll im Rahmen der allgemeinmedizinischen Ausbildung von Medizinstudierenden erprobt werden. Ein zielgruppenspezifisches, multimodulares Online-Angebot begleitet Medizinstudenten des 10. Semesters während ihres dezentralen Praktikums in hausärztlichen Praxen. Folgende Lehrziele werden angestrebt: (1) Einführung in das E-Learning, (2) Klinische Allgemeinmedizin - Online-Modul, (3) Chronic Care Online-Modul, (4) Online-Bewerbung. Die systematische Evaluation zeigt, dass E-Learning die Kommunikation der Studierenden untereinander und mit der universitären Lehreinheit während des Praktikum fördert. Auf der Grundlage der in diesem Pilotversuch gewonnenen Erfahrungen erscheint die Kombination mit Präsenzunterricht (Blended Learning) eine vielversprechende Option für die allgemeinmedizinische Ausbildung zu sein.
