o Establish and test explanatory hypotheses
Components of the Health History
Identifying data – age, gender, marital status, occupation
o Source of hx. - usually pt. but could be family or friend, letter of referral or
clinical record

Reliability- pt. memory, trust, mood
Chief Complaint- one or more symptoms or concerns causing pt. to seek care

peripheral vasc., urinary, genitals, musculoskeletal, psych, neuro,
hematologic, endocrine.
All this health hx. is done with the following
o Physical exam
o Clinical reasoning
o Assessment
o Plan
o The quality clinical record
o Comprehensive vs. focused?
Comprehensive
o New pt.
o Identifies or rules out causes related to concerns
o Lengthy or difficult pt. complaint
o Platform for health promotion
o Has potential for increased health care savings and decreased testing
o Can be seen as a diagnostic test
Focused
o Problem focused
o Good for routine or urgent visits
o Symptoms related to specific body system.
**** MAKE SURE THE DATE IS ALWAYS ON THE HEALTH HX****
Subjective Data
What the patient tells you
“the symptoms and hx. From chief complaint through review of systems
Pain, reports “headache”
Objective Data
What you observe or detect through exam, lab results and test data
Psychical exam findings or signs
, Height 5’3, weight 73kg, purulent discharge, etc.
SOAP Note Documentation
Subjective, objective, assessment, plan
Make sure pertinent negatives or positives are specifically described
Avoid excessive detail
Described what you saw now what you did
Take measurements
Make sure tone is professional
Chap 2.
Evaluating Clinical Evidence
Initial step in evaluating diagnostic testing is ensuring validity of results
“does the test accurately identify whether a pt. has a disease?”
Compare to the “gold standard”
Test sensitivity and specificity of testing
o Sensitivity- probability that a pt. with the disease has a + test
o “true positive rate
o Specificity- the probability that a non-diseased pt. has a negative test.
o Known as the true negative rate
A negative result from a test with a test with high sensitivity (very low false neg.
rate) usually excludes the disease.
o SnNout- sensitive test with negative result rules OUT
o SpPIN- specific test with a positive result rules IN disease.
Positive predictive value (PPV)- probability that a person with a + test has the
disease
o Prostate Ca screening where a man with a PSA value greater than
4.0ng/mL has only a 30% probability of having prostate Ca found on
biopsy
Negative predictive value (NPV)- probability that a person with a – test does not
have the disease
o Among men with a PSA level of 4.0ng/mL or below, 85% are found to be
Ca free on biopsy.
Prevalence of disease- important to understand the prevalence of the disease
you are looking into- patient population- age, gender, location etc.
Likelihood ratios- probability of obtaining a given test result in a diseased patient
divided by the probability of obtaining a given test result in a non-diseased pt.
o A higher value (much >1) indicates that a positive test is much more likely
to be coming from a diseased person than from a non-diseased person,
increasing confidence that a person with a + result has the disease
Bayes Theorem- relates the direct probability of a hypothesis conditional on a
given body of data conditional on the hypothesis
Fagan Nomogram- terms of probability of having a disease.
o Read the pretest probabilities from the line on left then take a straight
edge and draw a line through the likelihood ration in the middle and read
the posttest line on the right
