RESUMEN
BACKGROUND: Peer-assisted learning is well established in medical education; however, peer tutors rarely act as assessors for the OSCE. In the compulsory, near-peer teaching programme covering basic medical skills at the University of Heidelberg, peer tutors serve as assessors on a formative OSCE. This study aimed to investigate the feasibility and acceptance of peer assessors and to survey the perceived advantages and disadvantages of their use. METHODS: In 2016 and 2017 all OSCE peer assessors (third to sixth-year medical students) and all of the peer-assessed students in 2017 (second-year-medical students) were invited to participate in a survey. Both groups were asked to complete a tablet-based questionnaire immediately after the OSCE. Peer assessors were asked to rate eight statements and the peer-assessed students to rate seven statements on a five-point Likert scale. Both were asked to comment on the advantages and disadvantages of peer-assessors. RESULTS: Overall, 74 of 76 peer assessors and 307 of 308 peer-assessed students participated in the study. 94% (67/74) of peer assessors and 90% (276/307) of the peer-assessed group thought that it is important to have peer tutors as assessors. Of the peer assessors, 92% (68/74) felt confident in giving structured feedback during the OSCE and 66% (49/74) felt they had improved their teaching skills. Of the peer-assessed students, 99% (306/307) were satisfied with their peers as OSCE assessors and 96% (292/307) considered the peer feedback during the OSCE as helpful. The participants mentioned structural benefits, such as lower costs, and suggested the quality of the OSCE was higher due to the use of peer assessors. The use of peer assessors was found to be beneficial for the learners in the form of high-quality feedback and an overall reduction in stress. Furthermore, the use of peer assessors was found to be beneficial for the peer assessors (improved teaching and clinical skills). CONCLUSION: From a learner's perspective, the use of peer assessors for a formative OSCE that is part of a near-peer teaching program aimed at junior medical students is favourable for all. A broad implementation of peer assessment in the formative OSCE should be encouraged to investigate effects on quality and stress-reduction.

OBJECTIVES: To assess the acceptability and swallowability of several minitablets when administered as a unit dose compared with an equivalent dose of syrup in children aged 6 months to 5 years. STUDY DESIGN: The acceptability and swallowability of multiple drug-free minitablets in comparison with glucose syrup was assessed in 372 children of 2 age groups (186 in age group 1 [6-23 months of age] and 186 in age group 2 [2-5 years of age]) in a randomized, 3-way, single administration cross-over study. Age group 1 received 25 minitablets, 100 minitablets, and 5 mL syrup. Age group 2 received 100 minitablets, 400 minitablets, and 10 mL syrup. RESULTS: Superiority was demonstrated in age group 1 for acceptability (25 minitablets, P < .017; 100 minitablets, P < .0001) and swallowability (25 minitablets and 100 minitablets, both P < .0001) compared with syrup. In age group 2, noninferiority of acceptability was found only for 400 minitablets (P < .0003), not for 100 minitablets. Subgroup analysis revealed a strong sequential effect. For swallowability, noninferiority could be demonstrated for 100 minitablets (P < .01) but not for 400 minitablets. CONCLUSIONS: Administration of ≥25 minitablets is well-tolerated, feasible, and safe in children aged from 6 months, and was superior to the equivalent dose of syrup. Children aged >1 year accept ≤400 minitablets even better than the equivalent dose of syrup. Minitablets open the perspective for introducing small-sized solid drug formulations for all children, thus, further shifting the paradigm from liquid toward small-sized solid drug formulations.

BACKGROUND: The Objective Structured Clinical Examination (OSCE) is increasingly used at medical schools to assess practical competencies. To compare the outcomes of students at different medical schools, we introduced standardized OSCE stations with identical checklists. METHODS: We investigated examiner bias at standardized OSCE stations for knee- and shoulder-joint examinations, which were implemented into the surgical OSCE at five different medical schools. The checklists for the assessment consisted of part A for knowledge and performance of the skill and part B for communication and interaction with the patient. At each medical faculty, one reference examiner also scored independently to the local examiner. The scores from both examiners were compared and analysed for inter-rater reliability and correlation with the level of clinical experience. Possible gender bias was also evaluated. RESULTS: In part A of the checklist, local examiners graded students higher compared to the reference examiner; in part B of the checklist, there was no trend to the findings. The inter-rater reliability was weak, and the scoring correlated only weakly with the examiner's level of experience. Female examiners rated generally higher, but male examiners scored significantly higher if the examinee was female. CONCLUSIONS: These findings of examiner effects, even in standardized situations, may influence outcome even when students perform equally well. Examiners need to be made aware of these biases prior to examining.

BACKGROUND: It is still unclear to what extent the PBL tutor affects learning in PBL-sessions. This mixed-methods study (Part 1 and 2) evaluated the effects of facilitative (f) versus non-facilitative (nf) tutoring roles on knowledge-gain and group functioning in the field of endodontics. METHODS: Part 1 was a quantitative assessment of tutor effectiveness within a prospective, experimental, single-blind, stratified, randomized, two-group intervention study. Participants attended PBL in the context of a hybrid curriculum. A validated questionnaire was used and knowledge assessments were conducted before and after the intervention. External observers rated tutor performance. Part 2 was a qualitative assessment of tutor effectiveness and consisted of semi-structured expert interviews with tutors and focus group discussions with students. RESULTS: Part 1: f tutors obtained significantly higher scores than nf tutors with respect to learning motivation and tutor effectiveness (p ≤ 0.05). nf tuition resulted in a slightly larger knowledge gain (p = 0.08). External observers documented a significantly higher activity among facilitative tutors compared to non-facilitative tutors. Part 2: Tutors found the f role easier although this led to a less autonomous working climate. The students rated f tutoring as positive in all cases. CONCLUSIONS: With respect to PBL-group performance, students felt that groups guided in a non-facilitative fashion exhibited a higher level of independence and autonomy, especially with increasing PBL experience. In addition, students reported that more preparation was necessary for sessions guided by a non-facilitative tutor. Tutors were able to modify their role and influence group processes in a controlled manner. Results are useful for future "Train-the-Teacher" sessions.

OBJECTIVE: To evaluate the suitability of drug-free solid dosage forms (2 mm mini-tablets) as an alternative administration modality in neonates in comparison with syrup. STUDY DESIGN: A total of 151 neonates (inpatients; aged 2-28 days; median 4 days) were recruited. An open, randomized, prospective cross-over study was conducted to compare the acceptability and swallowability of 2 mm uncoated mini-tablets compared with .5 mL syrup. RESULTS: All neonates (N = 151) accepted the uncoated mini-tablet as well as the syrup (both formulations 100%; 95% CI 97.6%-100.0%; primary objective). The level of swallowability of uncoated mini-tablets was not inferior (P < .0001), in fact even higher (difference in proportions 10.0%; 95% CI 1.37%-19.34%; P = .0315) compared with syrup. Both pharmaceutical formulations were well tolerated, and in none of the 151 neonates, serious adverse events occurred; particularly none of the neonates inhaled or coughed in either of the formulations. CONCLUSIONS: The administration of uncoated mini-tablets proved to be a valuable alternative to syrup for term neonates. Our data on neonates close the age gap of prior findings in toddlers and infants: uncoated mini-tablets offer the potential of a single formulation for all age groups. These findings further shift the paradigm from liquid toward small-sized solid drug formulations for children of all age groups, as the World Health Organization proposes.

BACKGROUND: Computer-based examinations (CBE) ensure higher efficiency with respect to producibility and assessment compared to paper-based examinations (PBE). However, students often have objections against CBE and are afraid of getting poorer results in a CBE.The aims of this study were (1) to assess the readiness and the objections of students to a CBE vs. PBE (2) to examine the acceptance and satisfaction with the CBE on a voluntary basis, and (3) to compare the results of the examinations, which were conducted in different formats. METHODS: Fifth year medical students were introduced to an examination-player and were free to choose their format for the test. The reason behind the choice of the format as well as the satisfaction with the choice was evaluated after the test with a questionnaire. Additionally, the expected and achieved examination results were measured. RESULTS: Out of 98 students, 36 voluntarily chose a CBE (37%), 62 students chose a PBE (63%). Both groups did not differ concerning sex, computer-experience, their achieved examination results of the test, and their satisfaction with the chosen format. Reasons for the students' objections against CBE include the possibility for outlines or written notices, a better overview, additional noise from the keyboard or missing habits normally present in a paper based exam. The students with the CBE tended to judge their examination to be more clear and understandable. Moreover, they saw their results to be independent of the format. CONCLUSIONS: Voluntary computer-based examinations lead to equal test scores compared to a paper-based format.

BACKGROUND: Infection control partially depends on hygiene and communication skills. Unfortunately, motivation for continuous training is lower than desired. Many health care providers (HCPs) do not recognize the need for training but express this need for others. This is attributable to heuristic errors, such as the overconfidence effect. The aim of this study was to quantify the flawed self-assessment in infection-control. METHODS: In this cross-sectional multicenter study, 255 HCPs of different specialties participated in the 29-item, 5-point Likert scale questionnaire, assessing perceived proficiency in hand hygiene and communication skills for both themselves and others (colleagues, trainees, and supervisors of their own specialty and HCPs of others). RESULTS: 222 of 255 surveys could be analyzed. Respondents rated themselves to be better trained in handhygiene (P < .001) than trainees, colleagues, and supervisors; the same was seen for feedback skills (P < .001). HCPs of other specialties were consistently rated worse in all aspects (P < .001). CONCLUSION: Results show an overplacement effect in infection prevention skills. The belief of being well educated creates a subjective conviction that no further education in hand hygiene is needed. Thus, HCPs may face motivation barriers that require specialized programs to overcome these beliefs.

BACKGROUND: Practical skills are often assessed using Objective Structured Clinical Skill Exams (OSCE). Nevertheless, in Germany, interchange and agreement between different medical faculties or a general agreement on the minimum standard for passing is lacking. METHODS: We developed standardized OSCE-stations for assessing structured clinical examination of knee and shoulder joint with identical checklists and evaluation standards. These were implemented into the OSCE-course at five different medical faculties. Learning objectives for passing the stations were agreed beforehand. At each faculty, one reference examiner scored independently of the local examiner. Outcome of the students at the standardized station was compared between faculties and correlated to their total outcome at the OSCE, to their results at the Part One of the National Medical Licensing Examination as a reference test during medical studies and to their previous amount of lessons in examining joints. RESULTS: Comparing the results of the reference examiner, outcome at the station differed significantly between some of the participating medical faculties. Depending on the faculty, mean total results at the knee-examination-station differed from 64.4% to 77.9% and at the shoulder-examination-station from 62.6% to 79.2%. Differences were seen in knowledge-based items and also in competencies like communication and professional manner. There was a weak correlation between outcome at the joint-examination-OSCE-station and Part One of the National Medical Licensing Examination, and a modest correlation between outcome at the joint-examination-station and total OSCE-result. Correlation to the previous amount of lessons in examining joint was also weak. CONCLUSION: Although addressing approved learning objectives, different outcomes were achieved when testing a clinical skill at different medical faculties with a standardized OSCE-station. Results can be used as a tool for evaluating lessons, training and curricula at the different sites. Nevertheless, this study shows the importance of information exchange and agreement upon certain benchmarks and evaluation standards when assessing practical skills.

BACKGROUND: Although Peyton's four-step approach is a widely used method for skills-lab training in undergraduate medical education and has been shown to be more effective than standard instruction, it is unclear whether its superiority can be attributed to a specific single step. PURPOSE: We conducted a randomized controlled trial to investigate the differential learning outcomes of the separate steps of Peyton's four-step approach. METHODS: Volunteer medical students were randomly assigned to four different groups. Step-1 group received Peyton's Step 1, Step-2 group received Peyton's Steps 1 and 2, Step-3 group received Peyton's Steps 1, 2, and 3, and Step-3mod group received Peyton's Steps 1 and 2, followed by a repetition of Step 2. Following the training, the first independent performance of a central venous catheter (CVC) insertion using a manikin was video-recorded and scored by independent video assessors using binary checklists. The day after the training, memory performance during delayed recall was assessed with an incidental free recall test. RESULTS: A total of 97 participants agreed to participate in the trial. There were no statistically significant group differences with regard to age, sex, completed education in a medical profession, completed medical clerkships, preliminary memory tests, or self-efficacy ratings. Regarding checklist ratings, Step-2 group showed a superior first independent performance of CVC placement compared to Step-1 group (P<0.001), and Step-3 group showed a superior performance to Step-2 group (P<0.009), while Step-2 group and Step-3mod group did not differ (P=0.055). The findings were similar in the incidental free recall test. CONCLUSION: Our study identified Peyton's Step 3 as being the most crucial part within Peyton's four-step approach, contributing significantly more to learning success than the previous steps and reaching beyond the benefit of a mere repetition of skills demonstration.
