Traditional Expert-Based Information Delivery Systems Using an Expert, Being an Expert
Roles of Experts • Consultation • CME • Review articles • Practice guidelines • Decision analysis
Using an Expert/Being an Expert • Definition of an expert • Subspecialist or primary care clinician with special interest • Anyone/anything you go to for an answer to a question
Using an Expert/Being an Expert • “Never ask the barber whether you need a haircut” • “So many specialists fall into the habit of looking where the light is -- that is, offering solutions only in territory familiar to them. . . Wonderful examples exist of otherwise excellent researchers who are unable and unwilling to recognize evidence contrary to their beliefs.”
Usefulness Score • Work: Low • Significant potential for usefulness • Relevance: Varies • Validity: Expert dependent • If either relevance or validity is zero, usefulness is zero
Types of Experts • Content Expert • Clinical Scientist • YODA
Content Expert • Experienced, particularly diagnosis and procedures, not necessarily therapy • Not trained in clinical epidemiology (validity) • Traditional education favors DOEs (relevance) • May not be current, may rely on anecdotes • Risky extrapolation: Information is only as current as the last consultation
Clinical Disagreement Between/Within Experts • Same film: disagree 29% of time • Previous read: disagree with self 20% of time • Studied with venograms, fundi, MRI, angiography, mammograms, pathology (melanoma diagnosis) • March 97 Bandolier on the Web: “Histology as Art Appreciation”
“Never ask a barber . . .” • Chalmers: Recommendation highly correlated with training and source of income • Management of acute GI bleed • Surgeons: surgery- 50%; conservative- 15% • Internists: surgery- 15%; conservative- 50%
Clinical Scientist • Good at evaluating evidence; up-to-date, don’t have to be content experts • Separation of therapeutics • Medical Librarian, PharmD
YODA: Your Own Data Analyzer • Content expert and clinical scientist • Consider POEMs first, even if this information conflicts with DOEs or clinical experience • When POEMs not available, use best DOEs with an open mind • Demonstrate appropriate validity assessments • Not to be confused with YUCKs
YUCK • YOUR • UNSUBSTANTIATED • CLINICAL • KNOW IT ALL
YUCK • Your Unsubstantiated Clinical Know-it-all • Maladaptive • Rigid, Dogmatic • All personality types, but people who see things in Red and Green can fall into the YUCK trap
The Golden Question: “That’s interesting . . . Is there any evidence that . . . ?”
Continuing Medical Education • People remember 90% of what they do, 75% of what they say, but only 10% of what they hear • How to make the 10% count
Is post-test performance improved? (DOE) • YES • Beware “Chinese-Dinner Memory Dysfunction”
Are patient outcomes improved? (POEM) • No . . .Multiple RCTs have failed to find a benefit from traditional lecture format (passive) • Maybe . . . with active (hands-on) workshops combined with close follow-up
Usefulness • Validity: Depends on the speaker • Relevance: Depends on POEM:DOE ratio • Work: Higher than it seems • NBA analogy (only last two minutes count) • Tracking down validity of new POEMs
Role of the Speaker • Present a good mix of POEMs highlighted by clinically relevant DOEs • Augment POEMs with clinical experience • Identify Level of Evidence (LOE)for listener
Role of the Listener • Identify, before the talk begins: • What you want to learn • What are the POEMs you need to know? • Actively evaluate information (CME worksheet) • When a change-inducing POEM is presented, validate: • By questioning the speaker • By cross-checking with other sources
Identifying “Common” POEMS • Will this information have a direct bearing on the health of my patients (is it something they care about)? • Is the problem common to my practice? • Is the intervention feasible? • If true, will it require me to change my current practice?
Newer Models for CME • Practice-based small group CME • Educational prescriptions • Point of care Sources • Team-based learning • Audience response systems • CME worksheet • Social media
