OBJECTIVE STRUCTURED CLINICAL EXAMINATION (OSCE) & OBJECTIVE STRUCTURED PRACTICAL EXAMINATION (OSPE) Dr. Jatin Bhatt Professor & Head, Surgery Dr. G. U. Kavathia Asso. Professor in Microbiology P. D. U. Govt. Medical college, Rajkot.
LEARNING OBJECTIVES OF THIS SESSION: : Ø Ø Definition of OSCE/OSPE. General outline of OSCE/OSPE Station profile of OSCE/OSPE Advantage & disadvantage of OSCE/OSPE
DEFINITION: OSCE is basically an organized framework consisting of multiple stations around which student rotates and at which student performs and are assessed on specific tasks.
OSCE Objective : examiners use a checklist for evaluating the trainees Structured: trainee sees the same problem and performs the same tasks in the same time frame Clinical Examination: the tasks are representative of those faced in real clinical situations
PURPOSE OF OSCE To make the Evaluation System as Reliable & Valid as possible Ø To Eliminate Variability (Examiners & Patients) Ø
OSCE It is a method of assessing a student’s clinical competence which is objective rather than subjective and in which the areas tested are carefully planned by the examiners. The clinical competence is broken down in to its various components e. g. taking a history / auscultation of heart / interpretation of ECG or coming to a conclusion on the basis of the findings. Each component is the objective of one of the stations in the examination
Does Shows how Knows Performance assessment in vitro: OSCEs OSPE
GENERAL OUTLINE : Skill to be tested is given in form of a specific question • To be answered in 4 -5 minutes • Each question is a station • For each question (station) a check list is prepared in advance • Check list prepared by breaking the skill to be tested into its vital components and precautions to be observed
CONDUCTING OSCE / OSPE v. Student rotates round a number of stations – about 20 v. Spends specified time on each station (45 minutes) v. On a signal (e. g. bell) moves to the next.
PROCEDURE STATION e. g. Taking history of a patient Examine eye of a patient QUESTION STATION • MCQs related to finding • Interpretation of lab report etc. 10
e. g. 1 History taking / Examining a patient - Examiner is present - Examiner Uses a check list to record the performance of the students. e. g. 2 Chest X-Ray/CT Scan inspection etc. . - No examiner - Student asked about his findings & interpretation at the next question station. 11

EXAM VENUE
SIMULATED PATIENT(EXAMINATION)
ADVANTAGES OF THE OSCE All components of clinical Exams are assesed So More Valid examination Can be used with larger number of students Reproducible Components of clinical Skills & standards of competencies are predetermined So Objectivity & Reliability is higher The variable of the examiner and the patient are to a large extent removed
DISADVANTAGES OF THE OSCE Knowledge and skills are tested in compartments & not tested in ability to look at the Pt. as a whole, So long case may also needed The OSCE may be demanding for both examiners and patients More time in setting it up
41
Adaptation of OSCE to be applied for evaluation of skills in preclinical and paraclinical subjects. v Basic format remains same i. e. procedure stations and question stations. v Can be used as supplement to different method of evaluation 42
