5 Taxonomical Domains

6 Taxonomical Domains (Benjamin Bloom-1956)
 COGNITIVE DOMAIN (Intellectual Skills)  PSYCHOMOTOR DOMAIN (Practical Skills)  AFFECTIVE DOMAIN (Attitude / Emotional Areas)

7 Factors influencing performance

8 Factors Influencing Assessment
Student performance Patient performance Non standard marking system Examiner bias STUDENT ASSESSMENT

9 Why ? WHY OSPE /OSCE?

10 Lack of Standardisation Subjectivity
Drawbacks of the traditional methods of assessing clinical performance: Lack of structure Lack of Standardisation Subjectivity

11 and ‘structure’. The two major underlying principles of the OSCE are
‘objectivity’ and ‘structure’.

12 A well-designed OSCE has a high level of
Validity (the OSCE assesses what it is designed to assess) Reliability (the examination results are reproducible with very little error)

13 What ? What is OSCE/OSPE

14 What is an OSCE / OSPE? Objective Structured Clinical / Practical
Examination Harden RG and Gleeson FA Assessment of clinical competence using an objective structured clinical examination (OSCE) Medical Education,1979, Vol 13: 41-54

15 OSCE - Objective All the candidates are presented with the same test
Specific skill modalities are tested at each station History taking Explanation Clinical examination Procedures

16 OSCE - Structured The marking scheme for each station is structured
Structured interaction between examiner and student

17 OSCE – Clinical Examination
Test of performance of clinical skills Candidates have to demonstrate their skills, the psychomotor skills and not theoretical knowledge

18 OSCE Definition: An approach to the assessment of clinical competence in which the components of competence are assessed in a planned or structured way with attention being paid to the objectivity of the examination”. Harden, 1988

19 Observation of professional practice
The OSCE in relation to the Miller’s pyramid Observation of professional practice OSCE/OSPE MCQ, MEQ, Essay MCQ, SAQ Professional Behavior Behaviour/ Attitude skills Does Shows How Knows How Cognition knowledge Knows

20 How? How to conduct an OSCE?

23 STATION : TWO TYPES EXAMINER OBSERVES STUDENT ANSWERS ON
PROCEDURE STATION e.g. Taking history of a patient Examine eye of a patient EXAMINER OBSERVES STUDENT ANSWERS ON THE ANSWER SHEET QUESTION STATION MCQs related to finding Interpretation of lab report etc. 23

24 1.Resuscitation of a child 2.Communication skills
3.Physical examination skills 2. 3.

25 Patient simulator

26 Obtain written consent Collapse history Cranial nerve examination
Interpreting ECG Breaking bad news Insertion of NG tube Respiratory Examination I V Fluid prescription Chest pain history CPR Communication Skill History taking Skill Examination Skill Critical reasoning Skill Procedural skill

27 Specification Table Content Area Blood CVS Resp. CNS Endo.
Competencies History taking 1,2 4 3 Physical Examination 5 6 7 8 Lab investigation 9 10 11 12 Interpretation of data 13,14 15,16 17,18 Treatment 19 20

28 PROCEDURE STATIONS Competencies that may be assessed
Physical examination Diagnostic procedure e.g. ophthalmoscopy Explanation about tests and procedures Educating patient about management e.g. use of inhaler for asthma

29 Competencies that may be assessed
QUESTION STATION Competencies that may be assessed Multiple choice questions related to findings Interpretation of lab findings x-rays of patient seen in the previous station. Calculating the BMI of a patient (given the details)

30 ADVANTAGES AND DISADVANTAGES OF OSCE

31 ADVANTAGES Wider sampling than traditional methods
Every candidate does same examination Greater opportunity for objectivity OSCE Stations are re-useable Better psychometrics than traditional methods

32 DISADVANTAGES Costly Time consuming to design & administer Needs space Training needed to achieve reliability Experience to administer If students not familiar with OSCEs, must be oriented to this assessment format

33 Objective Structured Practical Examination (OSPE)

34 4 2 3 5 1 10 8 7 6 9

35 Example of an OSPE Task - Examine the specimen of urine provided
for proteins. Check list: 1. Does he take a urine sample to 2/3 level in the test tube? 2. Does he boil upper 1/3 of the column? 3. Does he add 2% acetic acid drop by drop? 4. Does he compare change in the top layer with the bottom layer of urine?
