Center for Information Mastery
Information Mastery is the application of the principles of evidence-based medicine concepts and techniques to the day-to-day practice of medical care. The concepts were developed in the early 1990s by Allen F. Shaughnessy, PharmD, MMedEd of Tufts University and David Slawson, MD of the University of Virginia.
There are two main principles of Information Mastery. The first principle is that some information sources are more useful to practicing clinicians than other information sources. Conceptually, the usefulness of any information source depends on the relevance of the information in the source, the validity of this information, and the time, effort, and money required to access the information. These three characteristics can be related in this way:
Usefulness = (Relevance x Validity) / Work
-
Concept 1: Patient-Oriented Evidence that Matters (POEMs)
A POEM is information that helps clinicians to help patients live longer and better. It is direct evidence that a medical intervention, on average, lengthens life, decreases symptoms, and/or improves life quality.
POEM information contrasts with “disease-oriented evidence,” information about the nature of disease and treatments that does not directly demonstrate improvement in patient-oriented outcomes. The distinction is important since there are numerous examples of disease-oriented evidence that are contradicted by POEM information.
Disease-Oriented Outcome vs. Patient-Oriented Outcome
Disease-Oriented Outcome: Antibiotic treatment can sterilize the middle ear of children with acute otitis media.
Patient-Oriented Outcome: Antibiotic treatment does not decrease the duration or intensity of symptoms and increases the likelihood of a subsequent episode of acute otitis media.Disease-Oriented Outcome: Intensive glucose lowering can decrease A1c, blood glucose.
Patient-Oriented Outcome: Intensive glucose lowering does not decrease mortality.Disease-Oriented Outcome: Beta-carotene and vitamin E are good antioxidants.
Patient-Oriented Outcome: Neither vitamin prevents cancer or cardiovascular disease.Disease-Oriented Outcome: Erythropoietin in patients with chronic renal failure increases hemoglobin.
Patient-Oriented Outcome: Erythropoietin increases mortality in patients with chronic renal failure.Disease-Oriented Outcome: Varenicline can help some patients stop smoking.
Patient-Oriented Outcome: Varenicline increases the likelihood of cardiovascular disease.While disease-oriented evidence is important for forwarding medical science, changing practice based on this preliminary evidence may result in causing harm to patients.

Concept 2: The Usefulness Equation
Just as all medical information is not equally important, so too is there a difference between sources of information. The Usefulness Equation relates three attributes of information sources:
Usefulness of any info source = Relevance of info x Validity of info
Work needed to obtain info
Relevant information is applicable to one’s practice and is also focused on patient-oriented evidence that matters.Validity is where evidence-based medicine techniques are helpful. Differences in study design and study conduct influence our comfort in the validity of the results.
Work is the time, energy, and money needed to find the needed information. A benchmark for low work is that answers can be found in less than one minute.

Concept 3: Two Tools Are Needed to Become an “Information Master”
Tool #1: An information resource to hunt for information at the point of care
Concept 4: “Clinical Jazz”
“Clinical freedom implies doing what is best for patients, not simply doing whatever the clinician wants.” - North of England Guidelines on the Treatment of Asthma
Clinical jazz is a mix of the structure provided by the best available evidence coupled with the clinical experience necessary to understand what each patient needs.

Longitudinal Curriculum
Information Mastery is one of nine key themes that run through all four years of the medical curriculum. In this way, the concepts and practices of information mastery and evidence-based medicine are incorporated in both didactics and on clerkships.
- Year 1: Evidence-based medicine course (See TUSK)
- Year 2: CAP (Competency-based Apprenticeship in Primary care)
- Year 3: Information Mastery Workshop and Information Mastery presentations during the Family Medicine Clerkship
- Year 4: Family Medicine Exploration Elective
- Tufts University Family Medicine Residency at Cambridge Health Alliance: A three-year curriculum continues information mastery with practical experience in using information at the point of care.
