Clinical performance of medical students in Korea in a whole-task emergency station in the objective structured clinical examination with a standardized patient complaining of palpitations

ABSTRACT: This study assessed the clinical performance of 150 third-year medicalstudents in Busan, Korea in a whole-task emergency objective structured clinical examination station that simulated a patient with palpitations visiting the emergency department. The examination was conducted from November 25 to 27, 2019. Clinical performance was assessed as the number and percentage of students who performed history-taking (HT), a physical examination (PE), an electrocardiography (ECG) study, patient education (Ed), and clinical reasoning (CR), which were items on the checklist. It was found that 18.0% of students checked the patient’s pulse, 51.3% completed an ECG study, and 57.9% explained the results to the patient. A sizable proportion (38.0%) of students did not even attempt an ECG study. In a whole-task emergency station, students showed good performance on HT and CR, but unsatisfactory results for PE, ECG study, and Ed. Clinical skills educational programs for subjected student should focus more on PE, timely diagnostic tests, and sufficient Ed.

Project description:Introduction: The aim of the Objective Structured Clinical Examination (OSCE) is a standardized and fair assessment of clinical skills. Observing second clinical year medical students during a summative OSCE assessing a General Practice clerkship, we noticed that information exchange with peers led to a progressively faster and overly focused management of simulations. Therefore, we established a Multiple Scenario-OSCE (MS-OSCE) where all students had to manage the same chief complaint at a station but it's underlying scenarios being randomly changed during students' rotation through their parcours. We wanted to ensure they fully explore differential diagnosis instead of managing their task influenced by shared information. We wanted to assess if a MS-OSCE violates the assumption of objectivity and fairness given that students are not tested with the same scenarios. Methods: We developed and piloted five OSCE stations (chest pain, abdominal pain, back pain, fatigue and acute cough) with two or three different underlying scenarios each. At each station these scenarios randomly changed from student to student. Performance was assessed with a checklist and global rating. The effect of scenarios and raters on students' grades was assessed calculating the intraclass correlation coefficient with a fixed effect two level linear model. Results: A total of 169 students and 23 raters participated in the MS-OSCE. The internal consistency over all stations was 0.65 by Cronbach's alpha. The difference of the mean grades between the scenarios of a given chief complaint ranged from 0.03 to 0.4 on a 1 to 5 grading scale. The effect of scenarios on the variance of the final grades at each station ranged from 4% to 9% and of raters from 20% to 50% when adjusted for students' skills. Conclusions: The effect of different scenarios on the grades was relevant but small compared to the effect of raters on grades. Improving rater training is more important to ensure objectivity and fairness of MS-OSCE than providing the same scenario to all students.

Project description:BACKGROUND:Objective structured clinical examinations (OSCEs) are a useful method to evaluate medical students' performance in the clerkship years. OSCEs are designed to assess skills and knowledge in a standardized clinical setting and through use of a preset standard grading sheet, so that clinical knowledge can be evaluated at a high level and in a reproducible way. OBJECTIVE:This study aimed to present our OSCE assessment tool designed specifically for radiology clerkship medical students, which we called the objective structured radiology examination (OSRE), with the intent to advance the assessment of clerkship medical students by providing an objective, structured, reproducible, and low-cost method to evaluate medical students' radiology knowledge and the reproducibility of this assessment tool. METHODS:We designed 9 different OSRE cases for radiology clerkship classes with participating third- and fourth-year medical students. Each examination comprises 1 to 3 images, a clinical scenario, and structured questions, along with a standardized scoring sheet that allows for an objective and low-cost assessment. Each medical student completed 3 of 9 random examination cases during their rotation. To evaluate for reproducibility of our scoring sheet assessment tool, we used 5 examiners to grade the same students. Reproducibility for each case and consistency for each grader were assessed with a two-way mixed effects intraclass correlation coefficient (ICC). An ICC below 0.4 was deemed poor to fair, an ICC of 0.41 to 0.60 was moderate, an ICC of 0.6 to 0.8 was substantial, and an ICC greater than 0.8 was almost perfect. We also assessed the correlation of scores and the students' clinical experience with a linear regression model and compared mean grades between third- and fourth-year students. RESULTS:A total of 181 students (156 third- and 25 fourth-year students) were included in the study for a full academic year. Moreover, 6 of 9 cases demonstrated average ICCs more than 0.6 (substantial correlation), and the average ICCs ranged from 0.36 to 0.80 (P<.001 for all the cases). The average ICC for each grader was more than 0.60 (substantial correlation). The average grade among the third-year students was 11.9 (SD 4.9), compared with 12.8 (SD 5) among the fourth-year students (P=.005). There was no correlation between clinical experience and OSRE grade (-0.02; P=.48), adjusting for the medical school year. CONCLUSIONS:Our OSRE is a reproducible assessment tool with most of our OSRE cases showing substantial correlation, except for 3 cases. No expertise in radiology is needed to grade these examinations using our scoring sheet. There was no correlation between scores and the clinical experience of the medical students tested.
