  • Background Q is about general knowledge not
    specific cases
  • Back ground Q is related to disease not patients?
  • K answer is not important, what is the kind of
    answer is more important
  • Questions
  • analytic
  • empirical
  • normative
  • So, for every types we have specific type of
    answer

6
Which answer is appropriate for different types
of questions?
  • Analytic answers are based on definitions,
    tautologies, A priori,
  • Empirical answers are based on experiments
  • Normative based on metaethics?

7
A five-step process for using an evidence-based
approach in general practice
  1. Define the problem
  2. Track down the information sources you need
  3. Critically appraise the information
  4. Apply the information with your patients
  5. Evaluate how effective the application of
    information is

8
The First Step in EBM
  • Develop a well-built, structured,
  • answerable clinical question

9
Answerable Question
  • ANSWERABLE means not subjective and . Because
    if you ask a subjective question from your
    colleagues s/he would answer because s/he catch
    the question but databases do not catch as they
    are not human!
  • So you should ask an answerable questions
  • Principally subjective / vague, could not be
    understand definitely so could not be answered
    correctly

10
Gaps in our medical knowledge a source of our
clinical questions
  • Range from miniscule to complete lack of
    familiarity with the patients need.
  • Negative response
  • Anxiety, shame, burnout
  • Positive response Embrace our opportunity to
    learn
  • Asking questions
  • Searching for answers
  • Channeling nervous energy into useful work

11
Where do the clinical questions come from?
  • Therapy
  • Diagnostic Test
  • Clinical Findings
  • Etiology
  • Differential Diagnosis
  • Prognosis
  • Prevention
  • Self-improvement

12
A clinical scenario
  • The patient is a 77-year-old man admitted for
    dyspnea and fever. He fell ill 4 days ago with
    low-grade fever, chills, myalgias, rhinorrhoea
    and a non-productive cough. One day ago he
    developed dyspnea on exertion, purulent sputum,
    lateral chest wall pain with inspiration and a
    shaking chill. His general health is fairly
    good He has had essential hypertension for 12
    years, well controlled on diuretic therapy. He
    has not smoked.

13
A clinical scenario (cont.)
  • On examination, his respiratory rate is 28, his
    heart rate is 108 and his temperature is 39.2C.
  • He have subtle cyanosis
  • His chest expands symmetrically
  • He has no wheezing
  • There is bronchophony and egophony in the left
    lower posterior lung field.

14
A clinical scenario (cont.)
  • Initial blood tests show leukocytosis and
    hyponatremia.
  • The team suspects acute community-acquired
    pneumonia with hypoxemia, and plans chest
    radiographs, sputum studies, supplemental oxygen
    and antimicrobial therapy

15
  • what are your questions
  • about this case?

16
A medical students questions
  • What microbial organisms can cause
    community-acquired pneumonia?
  • How does pneumonia cause egophony?
  • What is the incidence of community-acquired
    pneumonia?

17
Background question
  • Notice that the students questions ask for
    general or background knowledge about
    pneumonia, the disorder that explains much of
    this patients acute illness.
  • Epidemiology, Prevalence, Incidence,
    Pathophysiology, (as in the first parts of
    textbooks)

18
  • Background questions
  • Ask for general knowledge about a disorder
  • Two essential components
  • A question root (who, what, where, when, how)
  • A disorder, or an aspect of a disorder

19
A practitioners questions
  • In this patient, are clinical findings
    sufficiently powerful to rule in or rule out
    pneumonia?(Dx)
  • In this patient, is a Chest X-Ray necessary for
    the diagnosis?(Dx)
  • In this patient, is the probability of Legionella
    infection sufficiently high to warrant
    considering coverage of this organism using
    initial antibiotic choice? (Tx)
  • In this patient , do clinical features predict
    outcome well enough that as a low risk patient,
    he can be treated safely at home?

20
Foreground question
  • These questions ask for specific knowledge about
    diagnosis, prognosis, and treatment of patients
    with pneumonia, which might be called
    foreground knowledge.
  • Due to high turnover of foreground Q, always we
    have foreground Q and we should search in
    opposite to background Q

21
  • Foreground
  • The patient and/or the problem
  • The main intervention (defined very broadly,
    including an exposure, a diagnostic test, a
    prognostic factor, a treatment, a patient
    perception,)
  • Comparison intervention
  • The clinical outcome .

22
Foreground Questions
Background Questions
Experience
23
  • Questions
  • When did you publish your last paper?
  • When did you begin your study?
  • When was you paper accepted?
  • When was the new textbook renewed?
  • So, text books are not perfect resource to find
    foreground Q

24
Hallmarks of a good question
  • Relevant - Will the answer matter?
  • Answerable - Can the question be answered by
    research data?
  • Clear unambiguous, definite, objective
  • Worthy - Is the answer worth the work?

25
Formulating a clinical question
  • This skill can be improved by
  • Breaking the question down into its component
    parts
  • Classifying the question into a specific domain
  • therapy, diagnosis, prognosis, harm

26
Using the question to guide searching
  • Scenario - You are interested in checking the
    hearing of elderly patients, and have heard that
    the whispered voice test is good.
  • Question
  • Population in elderly patients does
  • Indicator a poor whispered voice test
  • Comparator a normal whispered voice test
  • Outcome predict abnormal audiogram
  1. Underline the key terms
  2. Number the order of importance from 1-4
  3. Think of alternate spellings, synonyms,
    truncations

47
What Types of Participants?
  • (Patient / Population)
  • Disease or condition of interest
  • Potential co-morbidity
  • Setting
  • Demographic factors

48
First component
  • Think about who / what you wish to apply this
    evidence to e.g.
  • People with a particular disorder?

54
What Types of Outcome?
  • For treatment, it includes all outcomes that are
    important to people, and lead to make decisions
    to define success of therapy
  • For prognosis, outcome is the chosen endpoint of
    the disease
  • (Mortality, Morbidity, Quality of life
    Disease-free period, admission period, pain, work
    absence,)

Diagnosis
  • P In an otherwise healthy 7-year-old boy with
    sore throat,
  • I - how does the clinical exam
  • C compare to throat culture
  • O in diagnosing Streptococcal infection?

63
Diagnosis
  • P In a 15 month old child with FTT
  • I is IgA antigliadin antibodies
  • C comparable to biopsy
  • O in diagnosing celiac disease?

64
Example
  • A TV programme has highlighted a hospital in
    Suffolk in which a stroke unit has been set up
    that specialises in the treatment of patients who
    have suffered strokes.
  • The hospital trust wants to know about the
    effectiveness of stroke units in terms of lives
    saved before deciding whether to invest in one.

71
Example
  • A acute cough is a common reason for patients to
    consult their GP. The causes of acute cough
    varies a lot. In GP the treatment often includes
    antibiotics.
  • The effectiveness of Abx is questionable and
    there has been a great deal of concern about
    bacterial resistance from over-prescribing.

Prognosis
  • P - In children with Down syndrome,
  • I - is IQ an important prognostic factor
  • C
  • O in predicting Alzheimers later in life?

78
Prognosis
  • P In a 14 year old teen with a low grade
    frontal oligodendroglioma, who is symptom free
  • I receiving standard therapy,
  • C
  • O what is life expectancy?

79
Etiology/Harm
  • P Controlling for confounding factors, do
    otherwise healthy children
  • I - exposed in utero to cocaine,
  • C compared to children not exposed
  • O have increased incidence of learning
    disabilities at age six years?

80
Etiology/Harm
  • P Does a newborn
  • I given vitamin K at birth
  • C compared to no vitamin K
  • O have an increase in cancer later in life?

81
Is PICO effective?
  • Use of PICO-structured forms resulted in more
    complex search strategies (P 0.002)
  • Clinical requests handled by PICO-structured form
    resulted in fewer items retrieved (P 0.028)
    i.e. more specific searches.
  • Librarians preferred minimally structured forms
    to PICO-structured forms in every dimension
    except informativeness.
  • (Booth A, et al. Structuring the pre-search
    reference interview a useful technique for
    handling clinical questions. Bull Med Libr Assoc.
    2000 Jul88(3)239-46)

82
Is PICO effective?
  • Only 20 of questions the intervention and the
    control groups were properly specified from at
    baseline.
  • 7/14 questions previously mis-specified in the
    intervention group were properly specified at
    follow-up (P 0.008). Control group showed no
    changes from baseline.
  • Intervention group more likely to explicitly
    describe patients (P 0.028), comparisons (P
    0.014), and outcomes (P 0.008).

Deciding which question to answer first
  1. What is the most important issue for this
    patient now?
  2. Which question, when answered, will help me
    most? (Has direct and significant impacts on
    decision-making)
  3. Most likely recur in my practice?

88
Example
  • A acute cough is a common reason for patients to
    consult their doctors. The causes of acute cough
    varies a lot. the treatment often includes
    antibiotics.
  • The effectiveness of Abx is questionable and
    there has been a great deal of concern about
    bacterial resistance from over-prescribing.

    well does an indeterminate result of a
    ventilation-perfusion scan rule out pulmonary
    embolism in a patient with a high pretest
    probability?

Broad or narrow questions?
  • Broad
  • Do drug X reduce mortality and morbidity in
    people with severe malaria?
  • Narrow
  • Do drug X suppositories reduce mortality in
    children with cerebral malaria?

95
What is the Best Treatment for Zoster?
  • What is the most cost-effective treatment for
    zoster if we consider pain reduction, quality of
    life and prevention of post-herpetic neuralgia?
  • Is famciclovir effective at preventing
    postherpetic neuralgia (defined as pain 3 months
    after rash healing) in otherwise healthy patients
    aged 60-70 who present within 48 hours of zoster
    rash, compared with placebo?

96
Example 1
You admit a 65 year old man with a stroke. On
examination you find that he has mild weakness of
the right arm and right leg and bilateral carotid
bruits. You send the patient for carotid doppler
ultrasonography and subsequently receive the
report that he has moderate stenosis (50-69 by
NASCET criteria) of the ipsilateral carotid
artery. You've noticed in the pile of journals
that is accumulating in your office that there
has been some recent literature addressing
surgical versus medical (ASAacetylsalicylic
acidAspirin) therapy for patients with
symptomatic carotid stenosis but you are unsure
what the results of these studies indicate. A
clinician could ask the following questions 1.
Can ASA (acetylsalicylic acid, Aspirin) decrease
the risk of stroke? 2. Does a carotid bruit
predict significant carotid stenosis? 3. How
effective is a carotid endarterectomy in someone
with moderate carotid stenosis? How can we make
well-built clinical questions from these clinical
dilemmas?
97
Example 1. Prevention
Patient or Problem 65 year old man with a stroke and moderate carotid stenosis

Comparison placebo
Outcome stroke
Question In a 65 year old man with a stroke and moderate carotid stenosis, can ASA decrease the risk of another stroke compared with no treatment?
98
Example 1. Diagnosis
Patient or Problem 65 year old man with a stroke

Question In a 65 year old man with a stroke, how precise and accurate is the presence of an ipsilateral carotid bruit for diagnosing significant carotid stenosis compared with doppler ultrasonography?
99
Example 1. Therapy
Patient or Problem 65 year old man with a stroke and moderate carotid stenosis
Intervention carotid endarterectomy
Comparison ASA
Outcome stroke
Question In a 65 year old man with stroke and moderate carotid stenosis, can carotid endarterectomy decrease the risk of stroke compared with medical therapy?
100
Example 2
You admit a 75 year old man with a stroke (left
sided weakness) who is having trouble ambulating,
feeding, bathing and dressing himself. He has
hypertension but it is well controlled with a
diuretic. He is otherwise well and now that he is
medically stable you decide after discussion with
him to transfer him to a stroke unit. His family
asks to see you because they are concerned about
this transfer. They live very close to the acute
care hospital and wonder why he can't stay on the
general medical ward where he currently is. You
arrange to meet with him and his family to
discuss their concerns. In the meantime, you
decide to review the evidence for the use of
stroke units. What clinical questions could you
ask?
101
Example 2
Patient or Problem 75 year old man with a stroke and residual weakness
Intervention admission to a stroke unit
Comparison general care
Outcome functional status
Question In an elderly man with a stroke, does admission to a stroke unit decrease the risk of death and dependency?
102
Example 3
You are a GP. Your middle-aged patient comes to
see you because of painful, weak, and stiff left
shoulder. A few days ago, while lifting some
heavy furniture, he felt a pop in the shoulder.
You suspect a rotator cuff tear and send him to
an orthopedic specialist. Your patient returns
after a couple of days, angry because the doctor
at the hospital first ordered an MRI, but since
the machine was not operational he used the
ultrasound, ensuring your patient that its all
the same. Your patient doesnt believe this to
be a valid diagnosis. Can you, by reviewing
evidence of diagnostic procedures in such cases,
persuade him to see the specialist again? What
clinical questions could you ask?
103
Example 3
Patient or Problem middle-aged man with a rotator cuff tear
Intervention ultrasound
Comparison MRI
Outcome diagnosis
Question Is diagnostic ultrasound imaging as accurate as MRI in detecting partial thickness rotator cuff tear in middle age?
104
Example
You admitted 4 year old boy with the diagnosis of
bacterial meningitis. Blood tests revealed
existence of IgM-class antibodies reactive to
antigens from H. influenzae. You wondered how
sure can you only by this test confirm the
diagnosis, but despite that questions, soon after
taking blood sample for hemoculture, you
introduced therapy with antibiotics. You are
familiar with the fact that 20 of cases of
meningitis caused by H. influenzae result in
complete or partial hearing loss. You also
remember that you read somewhere that risk of
this sequel may be lowered by application of
dexamethasone. Ask clinical question, search the
literarture, and appraise the results?
105

  • Educational tasks to be completed before session
  • Learner_________ Task___________

  • ___________

  • ___________
  • Presentations will cover
  • How you found what you found

108
Advantages of the educational prescription
  • It specifies the clinical problem that generated
    the question.
  • It states the question, in all of its key
    elements.
  • It specifies who is responsible for answering it.
  • It reminds everyone of the deadline for answering
    it (taking into account the urgency of the
    clinical problem that generated it).
  • Finally, it reminds everyone of the steps of
    searching, critically appraising and relating the
    answer back to the patient.

109
  • One tactic we use is to make specifying clinical
    questions an integral part of presenting a new
    patient to the group.
  • For example, we ask learners on our general
    medicine in-patient clinical teams, when
    presenting new patients, to tell us 33 things in
    3 minutes about each admission.

110
  • the final element of their presentations is the
    specification of an important question to which
    they need to know the answer and dont.
  • If the answer is vital to the immediate care of
    the patient, it can be provided at once by
    another member of the clinical team
  • Most of the time the answer can wait a few hours
    or days, so the question can serve as the start
    of an educational prescription.

111

  2. What you think the most likely diagnosis is.
  3. And the other items in your differential
    diagnosis.
  4. Any further diagnostic studies you plan to carry
    out.
  5. Your estimate of the patients prognosis.

116
A patient presentation
  1. How you will monitor the treatment.
  2. And what you will do if the patient doesnt

  3. The educational prescription you would like to
    write for yourself in order to better understand
    the patients disorder (background knowledge)
    or how to care for the patient (foreground
    knowledge) in order to become a better clinician.

Self-evaluation Answerable Questions
  • Are you asking any questions at all?
  • Are you
  • Asking 4 part questions?
  • Using education prescriptions?
  • Asking whats your evidence for that?
  • Is your success rate of asking answerable
    questions rising?
  • Do your questions compare with those of respected
    colleagues?
