OSCE
O OBJECTIVE S STRUCTURED C
CLINICAL E EXAMINATION
3

• Means fair and without bias. Most examination in
  the world are not fair. Use of checklist ensures
  objectivity.
• Rather than subjective, which is where the
  examiners decide whether or not the candidate
  fails based on their subjective assessment of
  their skills.

Objective
4

• Refer to the organization of the examination
• The OSCE is carefully structured to include parts
  from all elements of the curriculum as well as a
  wide range of skills.
• Instructions are carefully written to ensure that
  the candidate is given a very specific task to
  complete.

Structured
5

• the station are clinical in nature.
• . It is an examination with usually declares
  those who are competent to handle patients.
• the candidate is only asked questions that are on
  the mark sheet and if the candidate is asked any
  others then there will be no marks for them.

Clinical exam
6
OSCE ?

• Objective Structured Clinical Examination
• OR
• Over Stimulation and Crying Event
• OR
• Opportunity for Showing your Competence and
  Excellence

7
OSCE

• Why OSCE?
• WHAT DOES IT TEST ?
• HOW TO RUN IT?

8
WHY OSCE ?

• Increase validity and reliability
• More certain mapping to curriculum
• Better standard setting (pass score)
• More fair?
• More fun?

9
Long case

• One hour with the patient
• Full history and exam not observed
• Examiner bias .... unstructured questioning
  little agreement between examiners
• Some easy patients .. some hard ones
• Some co-operative patients some not
• Not a test of communication skills

10
With OSCE

• Clinical skill history, exam, procedure
• Marking structured and determined in advance
• Time limit
• Checklist/global rating scale
• Real patient/actor
• Every candidate has the same test

11
OSCEs reliable

• Less dependent on examiners foibles (as there
  are lots of examiners)
• Less dependent on patients foibles (as there are
  lots of patients)
• Structured marking
• More stations more reliable
• Wider sampling clinical, communication skills

12
OSCEs valid

• Content validity how well sampling of skills
  matches the learning outcomes of the course
• Construct validity people who performed well on
  this test have better skills than those who did
  not perform well
• Length of station should be authentic

13
OSCE performance

• Lucky?
• Nervous?
• Confident?
• Uncertain?
• Competent?
• Practised?
• Understood?

14
OSCE performance?
15
What does it test ?

• 1. History taking.
• Factual knowledge.
• 3. Interpretation of laboratory results and
  clinical data.
• Ability to formulate dd.
• 5. Counseling skills.
• 6. Clinical problem solving.

16
OSCEs acceptability

• Perceived fairness examiners and examinees
• Become widespread

17
OSCE design - blueprinting

• Map assessment to curriculum
• Adequate sampling
• Feasibility real patients, actors. manikins

18
1- Uniform scenarios for all candidates2.
Availability3. Safety, no danger of injury to
patients4. No risk of litigation5. Feedback
from Actors (simulators)6. Allows for Recall7.
Stations can be tailored to level of skills to be
assessed8. Allows for teaching audit9. Allows
for demonstration of emergency skills
Advantage of OSCE
19
Disadvantage of OSCE
1- Organizational training 2. The idealized
textbook scenarios may not mimic real-life
situations 3. Expensive
20
OSCE Preparations

• See one, do one, teach one ? see many, write
  some, learn some (learn how examiners think)
• Get a template
• Pick a topic from your block guides
• Core clinical presentations?
• Core clinical condition?
• Physical examination skill?
• Procedural or practical skill?
• Medical imaging?

21
OSCE Stations

• The OSCE is made up of a series of 10 minute
  stations with short breaks between stations
• The exam is made up of 10 minute couplet stations
  and 10 minute history or physical stations
• Couplet stations consist of a 5 minute clinical
  encounter followed by a 5 minute post-encounter
  probe (PEP)
• The PEP is a written station
• DDx, interpret test results, write orders or
  prescriptons, etc.

22
OSCE Stations

• 10 minute stations are usually history taking or
  physical examination stations.
• There is usually a oral question asked by the
  examiner at the 9 minute mark.

23
Couplet History Taking

• This is a 5 minute station with 5 minute PEP
• What the candidate reads
• Candidates Instructions
• Mrs. Fatma is 38 weeks pregnant lady complaining
  of headache
• This station is to test your ability to take
  relevant history in the next 5 minutes
• At the next station, you will be asked to answer
  questions about this patient.

24
Grade Failure Border line Pass
Marks 0 0.25 0.5
1. Age of patient
2. Duration of symptoms
3. Location of headache
4. Respond to simple analgesics ( pain killers)
5. Nausea or vomiting
6. Blurred vision
7. Swelling of hands, feet and face
8. Pain in upper abdomen ( epigastric)
9. Previous pregnancies (i.e. obstetric history)
10. Relevant Past medical history





25
Couplet History Taking

• Examiner asked to judge performance as
  Satisfactory (borderline/good/excellent) or
  Unsatisfactory (borderline/poor/inferior)
• This is a global rating
• If unsatisfactory there are several reasons
• Inadequate medical knowledge
• Could not focus
• Poor communication/interpersonal skills
• Potential harm to patient
• Dangerous act

  previous delivery ended by cesarean section due
  to failure to progress.
• She is now around 28 weeks
• Her family doctor have ordered a GTT and she
  brought the result for you for advise

34
Instruction for the Simulated Patient (Examiner)

• Doctor can you tell me is my GTT result normal or
  not?
• Is there any danger (complications) for me from
  this condition?
• Is there any risk for my baby?

consistency

• What important informations you want to know
  about this case?
• How would you confirm the patient diagnosis?

50
What important informations you want to know
about this case?
Yes

• Is she booked or not

38 weeks
No
51
How would you confirm the patient diagnosis?

• Symptoms
• Character of the pain regular in pattern,
  increase in frequency and intensity.

• Loss of fluid per vaginum

52
Common Mistakes

• Not reading the question!
• Asking too many unfocused questions (shotgun)
• Not explaining what you are doing during physical
  examination stations
• Rectal, vaginal and inguinal exams not allowed
  BUT you will not be given credit unless you
  indicate that you would do them when appropriate.
• Talking too fast and too much maintain
