26 September 2007 Student Assessment: New Ideas and Old Basics Louis Pangaro, MD Professor and Vice-chair for Educational Programs Department of Internal Medicine Uniformed Service University of the Health Sciences

“

clinical assessment”

• • • •

By teachers (house staff and faculty) On clinical rotations Based on words = descriptors Using words = descriptive

•

In vivo (vs. in vitro end of course/year)

What’s old?

• •

Suspicion of grades by teachers Teachers reluctance to be direct (honest?)

•

Belief that grading by teachers is subjective

•

Lawsuits about low grades

• Jamieson, Guidebook for Clerkship Directors, 2005.

What’s basic?

• We have an obligation • Fairness • Mentoring – The Hippocratic Oath • Professionalism – Duty and expertise (Pellegrino) 4

How it looked in 1987 •

lack of meaningful comments by evaluators

•

insufficient definition of evaluation criteria

•

too much inter-observer variability

•

late submission of evaluations

•

delay in feedback to students Tonesk X, Buchanan RG. J Med Ed. 1987

How it looked in 2001

• “Areas of weakness in current [clinical] evaluation models include psychometric properties associated with the tools, namely their questionable reliability and validity.” • Turnbull, International Handbook of Research in Medical Education, 2002.

How it looks in 2007

• • •

“Constructive criticism is hard to come by..” “…Candor is at least as painful to the provider as to the recipient…” “…faculty members feel uncomfortable inflicting pain even in a good cause like student improvement.”

• HMS Student Handbook, 2006-2007 7

focus • The emotional issues for teachers and learners in the grading process.

• Dealing with barriers to candor.

•

Quality: minimizing unwarranted variation in physician performance.

Wennberg

•

Faculty Development: minimizing unwarranted variation in teacher performance.

What’s new

• • • • •

A believe that quality methods can apply to teaching.

Search for more rigor.

“Best Evididence Med Ed” (BEBM) “Med Ed Research Certificate” MPH, MHPE programs

Today: describing success in clinical evaluations

New focus on evaluation in clincial setting:

• Attention to professional traits (Papadakis)

• Lawsuits by patients

Context of new methods • • • •

Objective Structured Clinical Exams 360 0 assessments Portfolios Descriptive vocabularies

–

To get more inter-rater agreement

–

To calibrate differences between levels of performance

FOCUSED PHYSICAL EXAMINATION

• •

[Norm] Exam is generally appropriate in scope and technique. Identifies major abnormalities and pertinent normal findings, only occasionally missing elements. Exam linked to history. Appropriate for level of training.

• HMS Clerkship Grading Form 14

FOCUSED PHYSICAL EXAMINATION (2)

• •

[Poor] Consistently misses important findings and often does not make appropriate connection between history and physical. Often uses faulty or inappropriate technique. Not organized or thorough.

FOCUSED PHYSICAL EXAMINATION (3)

• •

[Excellent] Exam is consistently superior. Uncovers subtle and important findings, incorporating advanced techniques where appropriate. Exceptionally organized and thorough, even on difficult cases.

ACGME Outcomes Project

•

New emphasis on outcomes (vs curriculum)

•

“long-term effort designed to emphasize educational outcome assessment in residency programs and in the accreditation process.”

ACGME: Outcomes: a cultural shift •

Designing Curriculum is no longer enough

•

Results must be demonstrated.

• •

A shift from process to product.

Content expertise not enough; need pedagogic expertise

Pangaro, Academic Med, 1999

Acceptance (1) Ob-Gyn

“The RIME method is a valid, logistically feasible and acceptable way of assessing medical student clinical performance… …..minimizes disadvantages of descriptive evaluation, and maximizes the opportunity for accurate observations and helpful feedback.”

APGO UME Taskforce: Espey et al, Am J Ob Gyn, 2007

Fairness Consistency Expectations

Principle 1 : Fairness

 to society :  valid (not arbitrary) and  sensitive to detect marginal performers  to students :  know what’s expected,  timely feedback  to teachers :  know what observations to make  protected (legally, emotionally) 26

Principle 2 : Consistency  Reliability - Within teacher - Between teachers - In same rotation or across blocks - Between sites in same clerkship - Between disciplines - suitable for high-stakes decisions 27

strategy

•

Simplicity leads to acceptance and use

•

Acceptance to consistency

•

Consistency to fairness

Fairness & Consistency Reliability &Validity = Stability of measurement and strength of inferences from observations

“ Old” beliefs in our culture

• Grading by teachers is subjective, Examinations are objective • Measurement > description, Numbers are > words 30

Framing the question more simply: • •

What do we expect of students?

Can we get all teachers to have the same expectations, and apply them consistently?

•

[A question of words and of conceptual frameworks]

Curricular Goals : ATTITUDES

•

The School of Medicine will ensure that before graduation a student will have demonstrated, to the satisfaction of the faculty, the following:

• A commitment to advocate the interests of one’s patients • Compassionate treatment of patients, and respect for their privacy and dignity • Honesty and integrity and dutifulness in all interactions with patients, their families, colleagues, and others with whom physicians interact • An understanding of, and respect for, the roles of other health care professionals, and the need to collaborate with others in caring for patients and promoting health • A commitment to provide care to patients who are unable to pay and to advocate for access to health care for members of underserved populations 40

2. Developmental Terms:

• “ Novice” can identify absence of pulse • • “Advanced learner” can distinguish specific arrythmias “Expert” can manage ventricular fibrillation 41

3. the “Synthetic”framework

• • • “syn-thetic” -putting the learner back together “K S A” are all required, integrated terms are a bit less generic, more behavioral 48

Pangaro, Academic Med, 1999

a framework to classify level of function

•

rudimentary reporting : “My patient has a fever, cough and a bad rash it’s vesicular or pustular ….”

•

rudimentary interpreting: “I think it might be due to chicken pox or herpes.”

•

rudimentary manager/educator : “I’d consider a smear of the fluid and a chest x ray . …We might observe or treat with acyclovir, …but I’m not sure. I’ll have to look this up.”

Alternative model R.I.M.E.

• Framework that is

–

developmental

–

behavioral

•

student can visualize, framework for observer

–

“synthetic”

“RIME”

• • • •

Reporter: takes ownership of getting the facts on every patient (“what”?) Interpreter: takes ownership of thinking and explaining (“why”?)… Manager: takes ownership of planning with patient (“how?)… Educator: takes ownership of developing and sharing expertise…

Matrix: transition to higher expectations

Duty and Expertise (Pellegrino)

• Each RIME “level” is a way of asking, does the student fulfill that promise • Making a diagnosis, not “giving” it.

• “Objective” • Does it affect teacher ratings?

Case using RIME:

• • •

W.O., student, “presents” Mrs. Jones: 45yo woman with acute lower back pain gives detailed description clinical picture suggestive of acute lumbar strain through physical examination,

–

blood pressure 130/80, heart rate 80

–

left-sided para-spinal tenderness L2 – L5

Case using RIME (continued)

• •

while student is writing up findings in the patient’s record, you interview and examine patient. Mrs. Jones asks: “Doctor, can you take my blood pressure since no one has?”

•

at what “RIME” level is this student?

Is the student ready for more responsibility – yes or no?

RIME is a razor.

Hemmer, Teach Learn Med, 2007

Limitations of our system

•

RIME is sometimes taken as developmental scheme.

•

The analytic model is very strong, and RIME is used for cognitive growth only.

•

Wanting to skip the Evaluation Sessions - they take time!

Basics Innovations

• Clinicians are good diagnosticians • We are mentors for our students • We promise society duty and expertise • Descriptors provide patterns and exemplars • Descriptive frameworks allow behavioral feedback • Synthetic frameworks make this simpler 74
