Abstract The purpose of this study was to determine whether the training module with a simulator of cardiology improves auscultation skills in medical students. Methods. Medical students of the third year after completing the module of the cardiovascular system of the discipline “Propaedeutics of internal diseases, passed a two-hour or four-hour training module in clinical auscultation with retesting immediately after the intervention and in the fourth year. The control group consisted of fourth-year medical students who had no intervention. Results. The diagnostic accuracy in two-hour training was 45.9% vs 35.3% in four-hour training p <.001. The use of a cardio simulator significantly increased the accurate detection of mitral regurgitation immediately after training on a simulator (more than 73%) p <.001. The next academic year, regression was observed in the diagnostic accuracy of mitral insufficiency in the intervention group after six months of observation by 4%. The auscultation skills of students at the bedside of real patients did not increase after training on a simulator: the accuracy of diagnosis of the auscultatory picture of the defect was equally low in the intervention group and the control group (35.0% vs 30.8%, p = 0.651). Conclusions. Two-hour training was more effective than four-hour training. After training on cardiac auscultation using a patient’s cardiological simulator, the accuracy rate was low in a situation close to the clinical conditions and a clinic on a real patient.

Study Design: Randomized, prospective study within an orthopedic surgery resident program at a large urban academic medical center. Objectives: To develop an inexpensive, user-friendly, and reproducible lumbar laminectomy bioskills training module and evaluation protocol that can be readily implemented into residency training programs to augment the clinical education of orthopedic and neurosurgical physicians-in-training. Methods: Twenty participants comprising senior medical students and orthopedic surgical residents. Participants were randomized to control (n = 9) or intervention (n = 11) groups controlling for level of experience (medical students, junior resident, or senior resident). The intervention group underwent a 40-minute bioskills training module, while the control group spent the same time with self-directed study. Pre- and posttest performance was self-reported by each participant (Physician Performance Diagnostic Inventory Scale [PPDIS]). Objective outcome scores were obtained from a blinded fellowship-trained attending orthopedic spine surgeon using Objective Structured Assessment of Technical Skills (OSATS) and Objective Decompression Score metrics. Results: When compared with the control group, the intervention group yielded a significant mean improvement in OSATS ( P = .022) and PPDIS ( P = .0001) scores. The Objective Decompression Scores improved in the intervention group with a trend toward significance ( P = .058). Conclusions: We conclude that a concise lumbar laminectomy bioskills training session can be a useful educational tool for to augment clinical education. Although no direct clinical correlation can be concluded from this study, the improvement in trainee’s technical and procedural skills suggests that Sawbones training modules can be an efficient and effective tool for teaching fundamental spine surgical skills outside of the operating room.

Abstract Background An increasing number of diagnostic decision support systems (DDSS) exist to support patients and physicians in establishing the correct diagnosis as early as possible. However, little evidence exists that supports the effectiveness of these DDSS. The objectives were to compare the diagnostic accuracy of medical students, with and without the use of a DDSS, and the diagnostic accuracy of the DDSS system itself, regarding the typical rheumatic diseases and to analyze the user experience. Methods A total of 102 medical students were openly recruited from a university hospital and randomized (unblinded) to a control group (CG) and an intervention group (IG) that used a DDSS (Ada – Your Health Guide) to create an ordered diagnostic hypotheses list for three rheumatic case vignettes. Diagnostic accuracy, measured as the presence of the correct diagnosis first or at all on the hypothesis list, was the main outcome measure and evaluated for CG, IG, and DDSS. Results The correct diagnosis was ranked first (or was present at all) in CG, IG, and DDSS in 37% (40%), 47% (55%), and 29% (43%) for the first case; 87% (94%), 84% (100%), and 51% (98%) in the second case; and 35% (59%), 20% (51%), and 4% (51%) in the third case, respectively. No significant benefit of using the DDDS could be observed. In a substantial number of situations, the mean probabilities reported by the DDSS for incorrect diagnoses were actually higher than for correct diagnoses, and students accepted false DDSS diagnostic suggestions. DDSS symptom entry greatly varied and was often incomplete or false. No significant correlation between the number of symptoms extracted and diagnostic accuracy was seen. It took on average 7 min longer to solve a case using the DDSS. In IG, 61% of students compared to 90% in CG stated that they could imagine using the DDSS in their future clinical work life. Conclusions The diagnostic accuracy of medical students was superior to the DDSS, and its usage did not significantly improve students’ diagnostic accuracy. DDSS usage was time-consuming and may be misleading due to prompting wrong diagnoses and probabilities. Trial registration DRKS.de, DRKS00024433. Retrospectively registered on February 5, 2021.

Abstract Background The illness script method employs a theoretical outline (e.g., epidemiology, pathophysiology, signs and symptoms, diagnostic tests, interventions) to clarify how clinicians organized medical knowledge for clinical reasoning in the diagnosis domain. We hypothesized that an educational intervention based on the illness script method would improve medical students’ clinical reasoning skills in the diagnosis domain. Methods This study is a randomized controlled trial involving 100 fourth-year medical students in Shiraz Medical School, Iran. Fifty students were randomized to the intervention group, who were taught clinical reasoning skills based on the illness script method for three diseases during one clinical scenario. Another 50 students were randomized to the control group, who were taught the clinical presentation based on signs and symptoms of the same three diseases as the intervention group. The outcomes of interest were learner satisfaction with the intervention and posttest scores on both an internally developed knowledge test and a Script Concordance Test (SCT). Results Of the hundred participating fourth-year medical students, 47 (47%) were male, and 53 (53%) were female. On the knowledge test, there was no difference in pretest scores between the intervention and control group, which suggested a similar baseline knowledge in both groups; however, posttest scores in the intervention group were (15.74 ± 2.47 out of 20) statistically significantly higher than the control group (14.38 ± 2.59 out of 20, P = 0.009). On the SCT, the mean score for the intervention group (6.12 ± 1.95 out of 10) was significantly higher than the control group (4.54 ± 1.56 out of 10; P = 0.0001). Learner satisfaction data indicated that the intervention was well-received by students. Conclusion Teaching with the illness script method was an effective way to improve students’ clinical reasoning skills in the diagnosis domain suggested by posttest and SCT scores for specific clinical scenarios. Whether this approach translates to improved generalized clinical reasoning skills in real clinical settings merits further study.

Abstract Context Some medical schools integrate STOP THE BLEED® training into their curricula to teach students how to identify and stop life threatening bleeds; these classes that are taught as single day didactic and hands-on training sessions without posttraining reviews. To improve retention and confidence in hemorrhage control, additional review opportunities are necessary. Objectives To investigate whether intermittent STOP THE BLEED® reviews were effective for long term retention of hemorrhage control skills and improving perceived confidence. Methods First year osteopathic medical students were asked to complete an eight item survey (five Likert scale and three quiz format questions) before (pretraining) and after (posttraining) completing a STOP THE BLEED® training session. After the surveys were collected, students were randomly assigned to one of two study groups. Over a 12 week intervention period, each group watched a 4 min STOP THE BLEED® review video (intervention group) or a “distractor” video (control group) at 4 week intervals. After the 12 weeks, the students were asked to complete an 11 item survey. Results Scores on the posttraining survey were higher than the pretraining survey. The median score on the five Likert scale items was 23 points for the posttraining survey and 14 points for the pretraining survey. Two of the three knowledge based quiz format questions significantly improved from pretraining to posttraining (both p<0.001). On the 11 item postintervention survey, both groups performed similarly on the three quiz questions (all p>0.18), but the intervention group had much higher scores on the Likert scale items than the control group regarding their confidence in their ability to identify and control bleeding (intervention group median = 21.4 points vs. control group median = 16.8 points). Conclusions Intermittent review videos for STOP THE BLEED® training improved medical students’ confidence in their hemorrhage control skills, but the videos did not improve their ability to correctly answer quiz-format questions compared with the control group.

ObjectiveTo design, implement and assess an online learning module for third-year and fourth-year medical students addressing medication safety.DesignThis study was a prospective, parallel, open-label, randomised controlled trial with two arms: (1) a control arm in which students were given five articles to read about medication safety, and (2) an intervention arm in which students were given access to an interactive web-based learning module on medication safety. Pretesting and post-testing were done online to evaluate change in medication safety knowledge.ResultsTen students completed the study in the intervention group (online module) and six students completed the study in the control group. The increase in score obtained on the post-test, relative to the pretest, was 15.4% in the group who completed the online module and 2.0% in the control group (difference=13.4%, 95% CI 0.5% to 26.2%, p=0.04).ConclusionStudents who completed an online educational tool about medication safety demonstrated a significantly greater increase in knowledge than those who completed a few readings. Online learning modules can be a convenient and effective means of teaching safe prescribing concepts to medical trainees.

ABSTRACT Objective: Training in practical aspects of disaster medicine is often impossible, and simulation may offer an educational opportunity superior to traditional didactic methods. We sought to determine whether exposure to an electronic simulation tool would improve the ability of medical students to manage a simulated disaster. Methods: We stratified 22 students by year of education and randomly assigned 50% from each category to form the intervention group, with the remaining 50% forming the control group. Both groups received the same didactic training sessions. The intervention group received additional disaster medicine training on a patient simulator (disastermed.ca), and the control group spent equal time on the simulator in a nondisaster setting. We compared markers of patient flow during a simulated disaster, including mean differences in time and number of patients to reach triage, bed assignment, patient assessment and disposition. In addition, we compared triage accuracy and scores on a structured command-and-control instrument. We collected data on the students' evaluations of the course for secondary purposes. Results: Participants in the intervention group triaged their patients more quickly than participants in the control group (mean difference 43 s, 99.5% confidence interval [CI] 12 to 75 s). The score of performance indicators on a standardized scale was also significantly higher in the intervention group (18/18) when compared with the control group (8/18) (p &lt; 0.001). All students indicated that they preferred the simulation-based curriculum to a lecture-based curriculum. When asked to rate the exercise overall, both groups gave a median score of 8 on a 10-point modified Likert scale. Conclusion: Participation in an electronic disaster simulation using the disastermed.ca software package appears to increase the speed at which medical students triage simulated patients and increase their score on a structured command-and-control performance indicator instrument. Participants indicated that the simulation-based curriculum in disaster medicine is preferable to a lecture-based curriculum. Overall student satisfaction with the simulation-based curriculum was high.

IntroductionA lack of preparedness for practice has been observed among new medical graduates. Simulation technology may offer one means of producing competency. This paper describes the application of a simulation-based intervention incorporating precision teaching (PT), a method of defining target skills, assessing individual progress and guiding instructional decisions, which is used to monitor learning and the development of behavioural fluency in other domains, to procedural skills training. Behavioural fluency refers to accurate and rapid responding that does not deteriorate with time, is resistant to distraction and can be adapted into new, more complex responses.MethodThis study used a between-groups design to evaluate the efficacy of a simulation-based intervention incorporating PT for teaching venepuncture among 11 medical students. The intervention consisted of timed learning trials during which participants carried out the skill in pairs and received corrective feedback. Two control groups of 11 untrained medical students and 11 junior doctors were also included in the study.ResultsIntervention group participants required an average of five trials and 21.9 min to reach the criterion for fluency. The intervention group demonstrated significantly higher accuracy in venepuncture performance than either control group. Improvements persisted over time, did not deteriorate during distraction, generalised to performance with patients and performance of an untargeted skill also improved.ConclusionsThe outcomes of this preliminary study support the application of PT within medical education. The implications of these data for clinical and procedural skills training are explored and suggestions are made for further research.

Many medical schools around the world have included professionalism training in their formal curriculum. However, these efforts may not be adequate; given the exposure of students to unprofessional behaviors in the clinical settings. In the present study, we aimed to design, implement, and evaluate a longitudinal program to improve professionalism among medical students upon their transition to clinical settings. A total of 75 medical students were enrolled in the study and randomly assigned to two groups. The control group did not receive any training, while for the intervention group; a 10-hour program through 16 weeks was organized based on the Holmes' reflection approach. The effectiveness of the program was evaluated by measuring three outcomes in both groups. Data analysis was performed using paired t-test and Multiple Linear Regression. Scores of judgment of professionalism increased in the intervention group (from 7.56 to 10.17; P< 0.001), while there was no significant improvement in the control group’s scores. Students' attitudes towards professionalism and their professional behaviors did not change significantly. Based on our findings, the Holmes reflection approach helps students improve their cognitive base of professionalism. Long-term follow-up and further qualitative studies will help us better understand the effects of this approach on other desirable outcomes.

Abstract Background: The Chinese medical students suffer from high prevalent mental health-related issues and low empathy. Effective strategies to improve the situations are lacking. This study aims to investigate the efficacy of the well-designed interventional courses to enhance the mental health and empathy of the senior Chinese medical students. Methods: A total of 146 3rd and 4th year medical students were randomized to intervention group (n=74) and control group (n=72). A pilot study including 5 pre-clinical students and 5 interns was first carried out to determine the themes and contents of the interventional courses. The designed courses were delivered in the intervention group once a month for three times, while the control group had no specific intervention. Five self-assessment questionnaires including the General Self-Efficacy (GSE), Medical Outcomes Study Short Form 8 (SF-8), Patient Health Questionnaire-9 (PHQ-9), Maslach Burnout Inventory (MBI), and Jefferson Scale of Empathy-Health Care Provider Student version (JSE-HPS) that separately evaluated the level of self-efficacy (SE), quality of life (QoL), depression, burnout, and empathy were completed by the students before and one month after the courses. Qualitative data were collected via e-mails two year after the intervention.Results: Compared to the control group, the interventional group showed significantly higher scores of the empathy (111.0 [IQR 102.0, 118.0] vs 106.0 [IQR 93.0, 111.5]; P = .01) and QoL (32.0 [IQR 28.0, 35.0] vs 29.5 [IQR 26.0, 34.0]; P = .04). The rate of depression was significantly decreased in the interventional group compared to that in the control group (13.5% vs 29.2%; Chi-square test, P = .02). However, no significant differences of self-efficacy (25.6 ± 4.8 vs 24.3 ± 6.3; P = .16) and burnout (27.0% vs 34.7%; Chi-square test, P = .31) were observed between the two groups.Conclusions: The well-designed interventional courses had a positive impact on the mental well-being and empathy in senior Chinese medical students, which may help provide novel information for incorporation into the medical school curriculum.
