This presentation

• Teaching clinical skills

• Evaluation of clinical skills

How do we teach clinical skills?

• Ask students to read the skill.

• Demonstrate it to the students.

• Ask students to re-demonstrate it.

• Correct the demonstrated skill.

• Ask student to re-re-demonstrate it.

Common problems with clinical teaching

Studentsactivity

Teachersactivity

Slice 3

Slice 4

•Lack of clear objectives and expectations •Teaching pitched at the wrong •level (usually too high) •Passive observation rather than•active participation of learners •Inadequate supervision and •provision of feedback

Common problems with clinical teaching

• Little opportunity for reflection and discussion

• "Teaching by humiliation"

• Informed consent not sought from patients

• Lack of respect for privacy and dignity of patients

• Lack of congruence or continuity with the rest of the curriculum

Challenges of clinical teaching •Time pressures •Competing demands clinical (especially when needs of patients and students conflict); administrative; research •Often opportunistic makes planning more difficult •Increasing numbers of students •Fewer patients (shorter hospital stays; patients too ill or frail; more patients refusing consent) •Often under-resourced •Clinical environment not "teaching friendly" (for example, hospital ward) •Rewards and recognition for teachers poor

A child with cough or difficulty breathing

• Essential skills (High morbidity, High mortality)

– Effective history taking– Physical examination– Identification of the patients problem– Formulation of the differential diagnosis– Planning of investigations– Management– Communication

Example of clinical teaching

• Decide whom you are teaching?– MBBS third year students (20 students)

• Decide what you want to teach?– Examination of the respiratory system.

• Decide how you want to teach?– Make four group.– Ask each group to list the organs that can be

examined applying inspection, palpation percussion and auscultation.

– Ask each group to write the normal findings.– Ask each group to list the diseases of each organ

and common clinical signs of these disease.

Example of clinical teaching (contd.)

• How I will know if students have understand?– Demonstrate examining a child for respiratory

system examination.– Divide student in group of 2.– Ask them to examine a patient.– Ask them to re-demonstrate specific clinical

procedure to elicit specific signs.– Discussion

How will I teach it?

Who I am teaching?

How will I know if the Student understand

Why we want to evaluate?

• Assessment drives learning.• Observe competency for the job

description.• Correct the mistakes.• Find out the prerequisite.• Find out the adequacy of the curriculum.

What do you want to evaluate?

• the existing knowledge of the disease.

• the communicating skill with patient/guardian.

• the writing skill.• the presentation skill.• the skill of eliciting signs.• the skill of diagnosing, investigating

and treating of specific problem.

Evaluating clinical skills• Clinical history writing.

– Poor reliability

• Log book– Good validity but often unreliable

• OSCE– Good reliability but may not be

reliable for overall skills.

Long case examination, as it exist

“Luck of the draw”*• Selection of the cases by examiners.• Distribution of cases randomly.• Approximately one hour for history, examination

and student to synthesize.

– Communication skill not observed at all.– Process is not observed.– Product is assessed.– Discussion frequently on the theory.– Approach and expectations vary with individual examiner.

*Stokes J. The clinical examination-assessment of clinical skills, medical education booklet no 2(Dundee Association for the Sudy of Medical Education)

Five required attributes of an assessment process:

Reliability - a measure of the variation in scores

Validity - the degree to which an assessment is a measure of what should be measured.

Acceptability - the degree to which the assessment process is acceptable

Feasibility - the degree to which the assessment can be delivered to all those who require

Educational impact - the degree to which the assessment can assist the student to improve his or her performance,

Evaluating clinical skills• Observed clinical examination:

– Good validity but poor reliability unless multiple observation made.

– Time consuming, logistic problems in recruiting patients.

• Non observed clinical examination– Poor reliability unless multiple cases seen.

Good validity.– No assessment of student interaction with

patient.

Reported Reliability when 4h testing times are used for different test formats

Improving the long case examination

• 1979: Harden and Gleeson developed the OSCE*

• 1997: Gleeson developed the OSLER**

*Harden RM, Gleeson FA. Assessment of clinical competence using an objective structured clinical examination (OSCE). Medical education, 1979;13:39-54.

** Gleeson F. Assessment of clinical competence using the objective structured long case examination record (OSLER). Medical Teacher. 1997; 19: 7-14

Objective Structured Long Examination Record

(OSLER)• Ten item analytical record form.

– 4 items for history taking, 3 items on physical examination, 1 each for formulation of investigations, management and clinical acumen in a logical sequence.

• All candidates are assessed on the same ten items.

• Time is 20-30 minutes for the examination.• Items are representatives: whole process.

OSLER’s components• History taking

– Clarity of presentation, communication process, systematic approach, establishment of case facts.

• Physical examination– Systematic approach, examination technique,

establishment of correct physical findings.• Assessment of clinical acumen

– Ability to identify and solve problems

Standardizing the long case based on the

difficulty of the case• Standard case

– Single problem

• Difficult case– Up to three

problem

• Very difficult case.– More than three

problem

Awarding marks in the OSLER

• P+: Very good/excellent. (60-80%0

• P: Pass/ bare pass. (50-55%)

• P-: Below pass

– Each items has to be graded followed by overall grade of the complete performance

Department of Child HealthExample of Paediatric Final Examination

• Observed by two examiner.• Filling the forms with specific tasks. • Grading the candidate.• Both examiners grade on the specific

tasks.• Average is taken.
