Deutsche medizinische Fachbereiche und Fakultäten sollen ihre Studienanfänger nach eigenen Kriterien aussuchen. Da bis zu 40 000 Bewerbungen pro Jahr erwartet werden können, ist eine Vorauswahl erforderlich, bevor arbeitsintensivere Auswahlmechanismen eingesetzt werden können. Wir haben einen Fragebogen konzipiert für den Versuch, zusätzlich zu schulischen Leistungen weitere Bewerbercharakteristika zu erfassen wie vorbestehendes medizinisch relevantes Wissen, musische, soziale, sportliche und berufliche Aktivitäten. Alle Studienanfänger des Wintersemesters 2005/2006 (860 Studierende) der Medizinischen Fachbereiche/Fakultäten an der Johann Wolfgang Goethe-Universität Frankfurt (FFM) und der Medizinischen Universität Innsbruck (MUI) wurden gebeten, diesen Fragebogen auszufüllen. Zum Wintersemester 2005/2006 wurde in FFM ausschließlich nach Abiturnote zugelassen, während die Zulassung an der MUI nach dem Posteingang der Bewerbung erfolgte, ohne Berücksichtigung von Schulnoten. Beide Gruppen (FFM 431 Studierende, MUI 429 Studierende) gaben vergleichbare nichtschulische Aktivitäten mit fast identischer Häufigkeit an, mit der Ausnahme der Ableistung eines Krankenhauspraktikums. Ein Pflegepraktikum wird von der deutschen Approbationsordnung verlangt, kann aber vor Studienbeginn absolviert werden, so dass deutsche Studienbeginner (sowohl Zulassung in FFM - 53%; deutsche Studienanfänger an der MUI - 67%) überwiegend ein Praktikum absolviert hatten, während österreichische Studienanfänger ein Praktikum wesentlich seltener abgeleistet hatten (14%). Derzeit sollten die erfassten nichtschulischen Leistungen als Zulassungskriterium für das Medizinstudium nur nach vorheriger Überprüfung der Eignung verwendet werden.
Background: The objective of the STREAM Trial was to evaluate the effect of simulation training on process times in acute stroke care.
Methods: The multicenter prospective interventional STREAM Trial was conducted between 10/2017 and 04/2019 at seven tertiary care neurocenters in Germany with a pre- and post-interventional observation phase. We recorded patient characteristics, acute stroke care process times, stroke team composition and simulation experience for consecutive direct-to-center patients receiving intravenous thrombolysis (IVT) and/or endovascular therapy (EVT). The intervention consisted of a composite intervention centered around stroke-specific in situ simulation training. Primary outcome measure was the ‘door-to-needle’ time (DTN) for IVT. Secondary outcome measures included process times of EVT and measures taken to streamline the pre-existing treatment algorithm.
Results: The effect of the STREAM intervention on the process times of all acute stroke operations was neutral. However, secondary analyses showed a DTN reduction of 5 min from 38 min pre-intervention (interquartile range [IQR] 25–43 min) to 33 min (IQR 23–39 min, p = 0.03) post-intervention achieved by simulation-experienced stroke teams. Concerning EVT, we found significantly shorter door-to-groin times in patients who were treated by teams with simulation experience as compared to simulation-naive teams in the post-interventional phase (−21 min, simulation-naive: 95 min, IQR 69–111 vs. simulation-experienced: 74 min, IQR 51–92, p = 0.04).
Conclusion: An intervention combining workflow refinement and simulation-based stroke team training has the potential to improve process times in acute stroke care.
Poster Während des klinischen Studienabschnittes bildet sich der Eindruck, dass Studierende entweder stärker an eher theoretischen Gebieten wie Innere Medizin, Pharmakologie oder Klinischer Chemie interessiert sind, oder an praktisch orientierten, meist operativen Disziplinen. Wir haben diese Hypothese am Fachbereich Medizin der Johann Wolfgang Goethe-Universität Frankfurt getestet mit den Prüfungsergebnissen für die Noten in den klinischen Fächern. Die Klausuren werden mit einem vergleichbaren Format in allen Fächern abgehalten, praktische Fähigkeiten werden durch OSCE-Prüfungen gemessen. Die derzeitige Datenbasis umfasst 300 - 1000 Studierende pro Fach. Die derzeitigen Ergebnisse zeigen eine stärkere Korrelation der Prüfungsleistungen in verwandten Fächern; die Korrelationen zwischen theoretischen und praktischen Prüfungsleistungen sind entgegen den Erwartungen nicht stark ausgeprägt. Bei der Interpretation ist zu berücksichtigen, dass die individuellen Leistungen auch durch andere Faktoren beeinflusst werden, wie die Notwendigkeit des Arbeitens, Tätigkeiten im Rahmen einer Dissertation oder extracurriculare Aktivitäten, die die Prioritäten in Klausuren oder praktischen Prüfungen von einer guten Note zum Bestehen ändern können. Auch die derzeitige Unsicherheit über die Bedeutung der Fachnoten trägt dazu bei, nicht in jedem Fall gute Noten erreichen zu wollen. Die derzeitigen Daten zeigen keine ausgeprägte Clusterung studentischer Lernleistungen; typischerweise sind individuelle Studierende entweder in allen Fächern herausragend, oder in keinem Fach.
Introduction: In an emergency department, the majority of pediatric trauma patients present because of minor injuries. The aim of this study was to evaluate temporal changes in age-related injury pattern, trauma mechanism, and surgeries in pediatric patients. Methods: This retrospective study included patients < 18 years of age following trauma from 01/2009 to 12/2018 at a level I trauma center. They were divided into two groups: group A (A: 01/2009 to 12/2013) and group B (B: 01/2014 to 12/2018). Injury mechanism, injury pattern, and surgeries were analyzed. As major injuries fractures, dislocations, and organ injuries and as minor injuries contusions and superficial wounds were defined. Results: 23,582 patients were included (58% male, median age 8.2 years). There was a slight increase in patients comparing A (n = 11,557) and B (n = 12,025) with no difference concerning demographic characteristics. Significant more patients (A: 1.9%; B: 2.4%) were admitted to resuscitation room, though the number of multiple injured patients was not significantly different. In A (25.5%), major injuries occurred significantly less frequently than in B (27.0%), minor injuries occurred equally. Extremity fractures were significantly more frequent in B (21.5%) than in A (20.2%), peaking at 8–12 years. Most trauma mechanisms of both groups were constant, with a rising of sport injuries at 8–12 years. Conclusion: Although number of patients increases only slightly over a decade, there was a clear increase in major injuries, particularly extremity fractures, peaking at 8–12 years. At this age also sport accidents significantly increased. At least, admittance to resuscitation room rose but without an increase of multiple injured patients.
Purpose: Despite the high number of patients with phalangeal fractures, evidence-based recommendations for the treatment of specific phalangeal fractures could not be concluded from the literature. The purpose of the present study was to assess current epidemiological data, classification of the fracture type, and mode of treatment.
Methods: This study presents a retrospective review of 261 patients with 283 phalangeal fractures ≥ 18 years of age who were treated in our level I trauma centre between 2017 and 2018. The data were obtained by the analysis of the institution’s database, and radiological examinations.
Results: The average age of the patients was 40.4 years (range 18–98). The ratio of male to female patients was 2.7:1. The two most typical injury mechanisms were crush injuries (33%) and falls (23%). Most phalangeal fractures occurred in the distal phalanx (P3 43%). The 4th ray (D4 29%) was most frequently affected. The P3 tuft fractures, and the middle phalanx (P2) base fractures each accounted for 25% of fracture types. A total of 74% of fractures were treated conservatively, and 26% required surgery, with Kirschner wire(s) (37%) as the preferred surgical treatment. The decision for surgical treatment correlated with the degree of angular and/or rotational deformity, intraarticular step, and sub-/luxation of specific phalangeal fractures, but not with age and gender.
Conclusions: Our findings demonstrated the popularity of conservative treatment of phalangeal fractures, while surgery was only required in properly selected cases. The correct definition of precise fracture pattern in addition to topography is essential to facilitate treatment decision-making.
Background: Clinical practice guidelines for patients with primary biliary cholangitis (PBC) have been recently revised and implemented for well-established response criteria to standard first-line ursodeoxycholic acid (UDCA) therapy at 12 months after treatment initiation for the early identification of high-risk patients with inadequate treatment responses who may require treatment modification. However, there are only very limited data concerning the real-world clinical management of patients with PBC in Germany. Objective: The aim of this retrospective multicenter study was to evaluate response rates to standard first-line UDCA therapy and subsequent Second-line treatment regimens in a large cohort of well-characterized patients with PBC from 10 independent hepatological referral centers in Germany prior to the introduction of obeticholic acid as a licensed second-line treatment option. Methods: Diagnostic confirmation of PBC, standard first-line UDCA treatment regimens and response rates at 12 months according to Paris-I, Paris-II, and Barcelona criteria, the follow-up cut-off alkaline phosphatase (ALP) ≤ 1.67 × upper limit of normal (ULN) and the normalization of bilirubin (bilirubin ≤ 1 × ULN) were retrospectively examined between June 1986 and March 2017. The management and hitherto applied second-line treatment regimens in patients with an inadequate response to UDCA and subsequent response rates at 12 months were also evaluated. Results: Overall, 480 PBC patients were included in this study. The median UDCA dosage was 13.2 mg UDCA/kg bodyweight (BW)/d. Adequate UDCA treatment response rates according to Paris-I, Paris-II, and Barcelona criteria were observed in 91, 71.3, and 61.3% of patients, respectively. In 83.8% of patients, ALP ≤ 1.67 × ULN were achieved. A total of 116 patients (24.2%) showed an inadequate response to UDCA according to at least one criterion. The diverse second-line treatment regimens applied led to significantly higher response rates according to Paris-II (35 vs. 60%, p = 0.005), Barcelona (13 vs. 34%, p = 0.0005), ALP ≤ 1.67 × ULN and bilirubin ≤ 1 × ULN (52.1 vs. 75%, p = 0.002). The addition of bezafibrates appeared to induce the strongest beneficial effect in this cohort (Paris II: 24 vs. 74%, p = 0.004; Barcelona: 50 vs. 84%, p = 0.046; ALP < 1.67 × ULN and bilirubin ≤ 1 × ULN: 33 vs. 86%, p = 0.001). Conclusion: Our large retrospective multicenter study confirms high response rates following UDCA first-line standard treatment in patients with PBC and highlights the need for close monitoring and early treatment modification in high-risk patients with an insufficient response to UDCA since early treatment modification significantly increases subsequent response rates of these patients.
Background: Surgical complications are associated with a significant burden to patients and hospitals and are increasingly discussed in recent literature. This cohort study reviewed surgery-related complications in a Level I trauma center. The effect of a complication avoidance care bundle on the rate of surgical complications was analyzed. Methods: All complications (surgical and nonsurgical) that occur in our trauma department are prospectively captured using a standardized documentation form and are discussed and analyzed in a weekly trauma Morbidity and Mortality (M&M) conference. Surgical complication rates are calculated using the annual surgical procedure numbers. Based on discussions in the M&M conference, a complication avoidance care bundle consisting of five measures was established: (1) Improving team situational awareness; (2) reducing operating room traffic by staff members and limiting door-opening events; (3) preoperative screening for infectious foci; (4) adapted preoperative antibiotic prophylaxis in anatomic regions with a high risk of infectious complications; and (5) use of iodine-impregnated adhesive drape. Results: The number of surgical procedures steadily increased over the study years, from 3587 in 2015 to 3962 in 2019 (an increase of 10.5%). Within this 5-year study period, the overall rate of surgical complications was 0.8%. Surgical site infections were the most frequently found complications (n = 40, 24.8% of all surgical complications), followed by screw malposition (n = 20, 12.4%), postoperative dislocations of arthroplasties (n = 18, 11.2%), and suboptimal fracture reduction (n = 18, 11.2%). Following implementation of the complication avoidance care bundle, the overall rate of surgical complications significantly decreased, from 1.14% in the year 2016 to 0.56% in the study year 2019, which represents a reduction of 51% within a 3-year time period. Conclusions: A multimodal strategy targeted at reducing the surgical complication rate can be successfully established based on a transparent discussion of adverse surgical outcomes. The combination of the different preventive measures was associated with reducing the overall complication rate by half within a 3-year time period.
Die Evaluation der studentischen Lehre - Basis für eine leistungsorientierte Mittelvergabe (LOM)?
(2008)
Die Evaluation der medizinischen Ausbildung wird am Fachbereich Medizin der J.W. Goethe – Universität Frankfurt seit 1998 systematisch durchgeführt. Damit ist diese Implementierung deutlich vor den bindenden Bestimmungen der Ärztlichen Approbationsordnung (in Kraft getreten am 01.10.2003) installiert worden. Die Evaluation der studentischen Lehre beinhaltet die Evaluierung sämtlicher Pflichtveranstaltungen (Kurse, Seminare, Praktika) durch einen standardisierten Fragebogen, der am Ende der Lehrpflichtveranstaltung (in jedem Semester) ausgeteilt und nach dem Ausfüllen durch die Studierenden wieder eingesammelt wird.
In dieser Kommunikation belegen wir anhand ausgewählter Beispiele (vom Wintersemester 2003/2004 bis zum Wintersemester 2005/2006), dass die anderen Orts oft vorgetragenen negativen studentischen Bewertungen der vorklinischen Fächer an der J.W. Goethe – Universität nicht zutreffen (Bsp.:Kursus Anatomie I, Makroskopischer Teil, WS 2005/2006: M=1,8, SD=0,86). Die Bewertung der didaktischen Qualität („Lehrstoff wurde gut verständlich präsentiert“) ist bei den meisten vorklinischen Pflichtveranstaltungen zufriedenstellend (Bsp.: Kursus Anatomie I, Makroskopischer Teil, WS 2005/2006: M=2,06, SD=0,94). Aus diesen Ergebnissen schließen wir auf eine positive Rückwirkung des curricularen und didaktischen Umbaus des Medizinstudiums an der Goethe – Universität.
Die Veröffentlichung der Ergebnisse der studentischen Evaluation („Zusammenfassende Beurteilung“) muss dem Umstand Rechnung tragen, dass praxisferne Fächer vielen Studierenden nur schwer zu vermitteln sind. Deswegen wird auf ein Ranking verzichtet. Nach diesen Ergebnissen wird ein Teil der Mittel leistungsorientiert vergeben (im jährlichen Zyklus). Diese leistungsorientierte Mittelvergabe (LOM) (davon 45 Prozent nach der studentischen Evaluation) beträgt 4 Prozent des jeweiligen Grundetats für Forschung und Lehre (Landeszuführung). Eine positive Lehrevaluation kann für eine Klinik/ein Institut einen wesentlich größeren Betrag bedeuten. Das Verfahren ist am Fachbereich akzeptiert.
As some cognitive functions decline in old age, the ability to decide about important life events such as medical treatment is endangered. Environmental support to improve the comprehension of health-related information is therefore necessary. With a small-scale explorative approach, the present survey study aimed at investigating person-environment fit (PE-fit) of support provided during medical consultations. This fit was calculated by assessing the match between aids provided by five medical practitioners during medical consultations and aids most appreciated by the geriatric patients (N = 88). The results showed that the largest discrepancies of used and appreciated aids could be found concerning the opportunity to discuss decisions with relatives, the possibility to take notes, the use of objects, pictures and a keyword list. Female patients indicated a lower PE-fit. These findings highlight discrepancies between the use of specific aids and the wishes of patients and call for thoughtful use of aids during consultations with geriatric patients.
Purpose: While more advanced COVID-19 necessitates medical interventions and hospitalization, patients with mild COVID-19 do not require this. Identifying patients at risk of progressing to advanced COVID-19 might guide treatment decisions, particularly for better prioritizing patients in need for hospitalization.
Methods: We developed a machine learning-based predictor for deriving a clinical score identifying patients with asymptomatic/mild COVID-19 at risk of progressing to advanced COVID-19. Clinical data from SARS-CoV-2 positive patients from the multicenter Lean European Open Survey on SARS-CoV-2 Infected Patients (LEOSS) were used for discovery (2020-03-16 to 2020-07-14) and validation (data from 2020-07-15 to 2021-02-16).
Results: The LEOSS dataset contains 473 baseline patient parameters measured at the first patient contact. After training the predictor model on a training dataset comprising 1233 patients, 20 of the 473 parameters were selected for the predictor model. From the predictor model, we delineated a composite predictive score (SACOV-19, Score for the prediction of an Advanced stage of COVID-19) with eleven variables. In the validation cohort (n = 2264 patients), we observed good prediction performance with an area under the curve (AUC) of 0.73 ± 0.01. Besides temperature, age, body mass index and smoking habit, variables indicating pulmonary involvement (respiration rate, oxygen saturation, dyspnea), inflammation (CRP, LDH, lymphocyte counts), and acute kidney injury at diagnosis were identified. For better interpretability, the predictor was translated into a web interface.
Conclusion: We present a machine learning-based predictor model and a clinical score for identifying patients at risk of developing advanced COVID-19.
