Does voluntary practice improve the outcome of an OSCE in undergraduate medical studies? A Propensity Score Matching approach

In Objective Structured Clinical Examinations (OSCE), students have to demonstrate proficiency in a wide array of medical knowledge and different skills, ranging from physical examinations to medical-practical skills and doctor-patient interactions. In this study, we empirically test the concept 'assessment drives learning' and investigate whether an OSCE motivates extracurricular, voluntary free practice (FP) of specific skills in a Skills Lab, and whether this has positive treatment effects on exam success in the respective parts of the OSCE. To explore causal inference with observational data, we used Propensity Score Matching (PSM) to generate a control and a treatment group that only differed in their practice behavior. For internal examinations and practical skills such as venous catheter placement and IM injections, we find strong, positive effects of FP that can result in a grade-jump. We further show that the presence and strength of effects depends on the complexity and type of the task. For instance, we find no effect for practicing venipuncture, and performance in communicative skills is associated with the willingness to repeatedly engage with instructional contents inside and outside the Skills Lab, and not with targeted practice of specific skills. We conclude that the anticipation of the complex OSCE is effective in motivating students to engage with a wide range of competencies crucial to the medical profession, and that this engagement has positive effects on exam success. However, consistent practice throughout the study program is necessary to sustain and nurture the acquired skills.

Clinical experience can compensate for inferior academic achievements in an undergraduate objective structured clinical examination

BACKGROUND

Practical and non-cognitive skills are essential to medical professions; yet, success in medical studies is primarily assessed with cognitive criteria. We show that practical exams can benefit students who have only average high school final grades, but working experience in medical professions.

METHODS

With a cross-sectional study, we compare the performance of undergraduate medical students with working experience in adjacent health-care professions (and below-average school leaving-grades) with students who entered medical school directly based on their excellent school records in an Objective Structured Clinical Examination (OSCE). For a sample of more than 1,200 students, we use information on OSCE scores in medical and practical skills, doctor-patient communication/interaction, performance in MC-exams, and core sociodemographic variables.

RESULTS

Waiting list students outperformed their classmates in the demonstration of practical skills. Students admitted via their excellent school grades scored best overall. This difference vanishes once we control for school-leaving grade and age, the two main factors separating the analysed groups. Students from the waiting list have a significantly smaller overall chance to reach excellent grades in the first two years of study.

CONCLUSIONS

Students who gathered experiences in health-care professions before enrolling at medical school can benefit from an expanded role of practical elements in medical studies. Student selection instruments should take these different starting positions and qualities of applicants into account, for example with a quota for the professionally experienced.

Gamification: Basic concepts and applications in radiology

Gamification is the use of elements from games in non-game environments, such as education. It is an alternative educational focus that promotes students' motivation and participation in the learning process. Gamification had proven effective in training health professionals and can play an important role in diagnostic radiology training, both at the undergraduate and postgraduate levels. Gamification activities can be carried out in real environments, such as classrooms or session rooms, but there are also interesting online modalities that favor remote access and user management. The possibilities of gamification in virtual worlds to teach undergraduate students radiology are very promising and deserve to be explored in training residents. This article aims to review general concepts in gamification and to present the main types of gamification used in medical training, pointing out its applications and advantages and disadvantages and emphasizing experiences in radiology education.

The objective structured clinical examination (OSCE): Main aspects and the role of imaging

The objective structured clinical examination (OSCE) is a format of examination that enables students to be evaluated in a uniform, standardized, reliable, and objective way. It is carried out in different clinical stations that simulate real clinical situations and scenarios. Numerous universities in Spain and other countries employ this approach for the final examination for medical school students. This update describes the organization, design, and fundamentals for the OSCE, proposing that radiology should form part of multidisciplinary OSCEs to the extent that it forms part of clinical practice. Moreover, it is interesting and opportune to introduce the OSCE in undergraduate and postgraduate training in radiology. Online platforms enable bidimensional OSCEs that are cost-effective in terms of staff, resources, and physical space, although this approach has certain limitations. Virtual world technologies make it possible to reproduce OSCE stations in three-dimensional scenarios; recent experiences in radiology have shown that this approach interests and motivates students and is widely accepted by them.

Can selection interviews predict OSCE performance? Evidence from Hannover Medical School

OBJECTIVES

We analyze whether the student selection process at Hannover Medical School (MHH), which combined a semi-structured interview with school leaving grades, can predict performances in an Objective Structured Clinical Examination (OSCE). We also check whether there are differences between assessments of clinical knowledge, practical skills, and communication abilities.

METHODS

We use data from 525 medical students who were admitted after a successful selection process and who completed the OSCE in the years 2015-2019. We employ multivariate regressions and a mediation analysis approach to learn whether study success after admission and prior to the OSCE mediates the outcome of the latter.

RESULTS

A better performance in the MHH's selection interview is unrelated to success in the OSCE. However, there is a small but significant influence of school grades on OSCE results in each part except for the assessment of communication skills. The impact of the school grade is partially mediated by performances in written and oral exams preceding the OSCE.

DISCUSSION

School grades matter for the OSCE outcome, albeit to different degrees for more learning-based vs. practical parts of the examination. The interview at MHH was purely informative and unrelated to study success, also in the assessment of communication skills. Better structured interview tools may yield better results.

CONCLUSION

Students' cognitive abilities predict study success in an undergraduate OSCE. Performances in a semi-structured selection interview have no impact, not even the assessment of communication skills.

[Structured reporting in radiology : IT essentials]

A clinically meaningful use of structured reporting, which in the opinion of numerous scientific societies and experts is a very important prerequisite for the further development of radiological findings, especially under quality aspects, requires corresponding standards for implementation in IT systems. In addition to DICOM ("digital imaging and communication in medicine"), these are other standards for coding, for example RadLex ("radiological lexicon") or the specification of so-called interoperability profiles, as they are being developed by IHE ("integrating the healthcare enterprise"). The management of radiology report templates (MRRT) profiles is the central building block for this. The building blocks for efficient IT implementation, which also allow harmonization, for example at a national level, are currently available. Users in radiology should familiarize themselves with them and demand appropriate solutions from manufacturers.

Classroom teaching with simulated patients during COVID-19: the communication skills course in the second year of the model medical curriculum HannibaL

Objective: In the spring of 2020 in response to the COVID-19 pandemic, the question arose at Hannover Medical School as to how simulated patients (SP) could still be utilized in the communication course that is part of the module "Diagnostic methods" taught in the second year of the model medical curriculum known as HannibaL. Methods: This short report summarizes the process of implementing the utilization of SP in analog classroom teaching and describes the relevant results on the concluding Objective Structured Clinical Examination (OSCE) in comparison to the previous year. Results: Overall, the analog SP deployments were practicable under local conditions and in compliance with precautionary measures to curb the risk of infection, whereby the OSCE scores did not deviate significantly from those in the prior year. Conclusion: During the COVID-19 pandemic and perhaps other epidemics as well, it will continue to be important in the future to make locally adapted, purpose-oriented, and preventively effective decisions regarding university didactics in undergraduate studies.
