“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)

3

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.

4

What’s basic?

• We have an obligation

• Fairness

• Mentoring – The Hippocratic Oath

• Professionalism– Duty and expertise (Pellegrino)

5

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

6

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.

7

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

8

focus

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

• Dealing with barriers to candor.

9

• Quality: minimizing unwarranted variation in physician performance.– Wennberg

• Faculty Development: minimizing unwarranted variation in teacher performance.

10

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

11

Today: describing success in clinical evaluations

12

New focus on evaluation in clincial setting:

• Attention to professional traits (Papadakis)

• Lawsuits by patients

13

Context of new methods

• Objective Structured Clinical Exams

• 3600 assessments

• Portfolios

• Descriptive vocabularies– To get more inter-rater agreement– To calibrate differences between levels of

performance

14

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

15

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.

16

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.”

19

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

20

ACGME “Competencies”(1999)

• Medical Knowledge

• Interpersonal & communication skills

• Professionalism

• Patient Care

• System-based Practice

• Practice-based learning & Improvement

• Medical Expert

• Communicator

• Collaborator

• Professional

• Manager

• Health Advocate

• Scholar

“R.I.M.E. Scheme”

– Reporter

– Interpreter

– Manager/Educator

Pangaro, Academic Med, 1999

24

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

25

Fairness

Consistency

Expectations

26

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 makeprotected (legally, emotionally)

27

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

28

strategy

• Simplicity leads to acceptance and use

• Acceptance to consistency• Consistency to fairness

29

Fairness & Consistency

Reliability &Validity =

Stability of measurement and strength of inferences from

observations

30

“ Old” beliefs in our culture

• Grading by teachers is subjective, Examinations are objective

• Measurement > description, Numbers are > words

31

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]

1. Analytic expression of Goals

– “ana-lytic”: takes the learner “apart”

– into domains, categories

– “attitude”, “skills”, “knowledge”

– considered separately

– generic terms

– useful for discrete assessments

38

Curricular Goals: KNOWLEDGE The School of Medicine will ensure that before graduation a student will have

demonstrated, to the satisfaction of the faculty, the following: • The capacity to recognize the limitations in one’s knowledge and clinical skills and

to make a commitment to engage in lifelong learning • Knowledge of the normal structure and function of each of the major organ

systems of the body and the current basic scientific mechanisms operative at the systemic, cellular, and molecular levels

• Knowledge of the various causes (genetic, developmental, metabolic, toxic, microbiologic, immune, psychosocial, neoplastic, traumatic, and degenerative) of illnesses and diseases

• Knowledge of the altered structure and function of the body and its major organ systems that are seen in various illnesses and diseases

• Knowledge of the scientific method in establishing the causation of disease and efficacy of traditional and non-traditional therapies

• Knowledge of health care policy and the economic, psychological, social, and cultural factors that affect health and health care delivery

• Knowledge of the most frequent clinical, laboratory, radiographic, and pathologic manifestations of common as well as life threatening diseases

• Knowledge about relieving pain and ameliorating the suffering of patients • Knowledge of the epidemiology of diseases and the systematic approaches useful

in promoting health • Knowledge of techniques of patient education and counseling in basic lifestyle

changes/prevention • Knowledge of and approaches to reduce the psychological and physical risks and

stresses of the practice of medicine

39

Curricular Goals: SKILLS • The School of Medicine will ensure that before graduation a student will have

49

“R.I.M.E. Scheme”

– Reporter

– Manager/Educator

Pangaro, Academic Med, 1999

50

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.”

51

• 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.”

52

Alternative model R.I.M.E.

• Framework that is

– developmental

– behavioral•student can visualize, framework for observer

– “synthetic”

53

“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…

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

59

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?

60

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

RIME is a razor.

73

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!

74

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

• Simplicity leads to acceptance and use

• Acceptance to consistency• Consistency to fairness
