thics of Hippocratic Medicine
Harnessing the principals of nature as guide to healing
Be of benefit and do no harm
Asclepius
“Taught medicine for those who were healthy in their nature but were
suffering from a specific disease; he rid them of it…then ordered them to live
as usual…for those however, whose bodies were always in a state of inner
sickness he did not attempt to prescribe a regime to make their life a
prolonged misery…medicine was not intended for them and they should not
be treated even if they were richer than Midas.”

Healing comes from God through human means

Usefulness of 4 Principals
A patient was given a dicloxicillin for a forearm cellulitis
despite having a clearly documented penicillin allergy in
the chart. He returned to the prescribing physician’s
office 3 days later with a cutaneous drug eruption. The
physician acknowledged and apologized for the error
and provided alternative therapy for the cellulitis. This
is an example of the practice of which ethical principle?

Patient is a 72 yo man with bilateral knee
DJD that has been treated with Vioxx for
the last 3 years with good relief. He had
a distant history of PUD and a previous
GI bleed that was positive for H. Pylori
infection-- (since treated). He arrived in

your office saying he read in the New
York Times that his medication may
increase his risk for heart attack and
stroke. He wants your advice.

NSAIDS were 16th leading cause of
death in US
VIOXX (Refocoxib)
• 1999- VIGOR (Vioxx GI Outcomes Trial)
– Refocoxib roughly 2/3 fewer GI ulcerations than
Naprosyn
– 5X increase in CV events…
– Barely mentioned in paper..
– Stated that effect due to cardio-protective naprosyn
– Topol and Colleagues suggest trials to evaluate in

CLASS Study (?)
Gastrointestinal toxicity with celecoxib vs nonsteroidal anti-inflammatory
drugs for osteoarthritis and rheumatoid arthritis: the CLASS study: A
randomized controlled trial. Celecoxib Long-term Arthritis Safety Study.
Pharmacia Clinical Research and Development, 4901 Searle Pkwy, Bldg A3E,
Skokie, IL 60077, USA.
MAIN OUTCOME MEASURES: Incidence of prospectively defined symptomatic
upper GI ulcers and ulcer complications (bleeding, perforation, and obstruction)
and other adverse effects during the 6-month treatment period. RESULTS: For all
patients, the annualized incidence rates of upper GI ulcer complications alone and
combined with symptomatic ulcers for celecoxib vs NSAIDs were 0.76% vs
1.45% (P =.09) and 2. 08% vs 3.54% (P =.02), respectively.
CONCLUSIONS: In this study, celecoxib, at dosages greater than those indicated
clinically, was associated with a lower incidence of symptomatic ulcers (AT 6
MONTHS) and ulcer complications combined compared with NSAIDs at standard
dosages.
Issues brought forward
1- FDA is beholding to the drug industry
– 1992 Prescription Drug Fee Act
– $825 million from industry (’93-’01)
• 4.9 million to lobby FDA in ’03 alone
– Drug approval time decreased- 2714 months
• Drug recalls1.56%5.35%
– >50% of FDA expert panel members received
honoraria from Pharma..
JAMA. 2000;284:1247-1255

Issues brought forward
2- Post-marketing surveillance
– FDA Medwatch
• depends upon voluntary reporting
• http://www.fda.gov/medwatch/
– Drug Manufacturers
• Less than half f/u studies promised initiated
• Fox guarding the henhouse..
Issues brought forward
• Direct marketing creates problems
– MERCK spends $100million/year
– We must figure out how to respond
Our fiduciary ETHICAL responsibility
–
–
–
–
refocoxib, cervistatin, troglitazone, rosiglitzone
Use medications with a “track record”
Report side effects to FDA
Company reps=salesmen
– $$ disincentive to report
– Be of benefit and do no harm..

The Schiavo Case

2- Theological
3- Political
Application of 4 boxes
March 31, 2005- 9:05 AM- Terri Schiavo dies- 21 years after her accident
Post-Cardiac Arrest Rule
The Schiavo Case
1- Medical Indications
-what % of patients
survive cardiac arrest on TV?
• 225,000 patients have sudden cardiac death in US
• 50% arrive at hospital alive
– 80% are in post-arrest coma, 14% survive to discharge
– NEJM. 2001;334:1304-13
• 5 clinical signs predict poor outcome
absent corneal reflexes at 24 hours (LR, 12.9; 95% confidence
interval [CI], 2.0-68.7)
absent pupillary response at 24 hours (LR, 10.2; 95% CI, 1.848.6)
absent withdrawal response to pain at 24 hours (LR, 4.7; 95% CI,
2.2-9.8)
no motor response at 24 hours (LR, 4.9; 95% CI, 1.6-13.0)
no motor response at 72 hours (LR, 9.2; 95% CI, 2.1-49.4).

The Schiavo Case
1- Medical Indications
- No chance for clinical improvement
2- Patient Preferences
Loss of cortical function with maintenance of brainstem
function-- eyes open unconsciousness with physiologic
function
sleep/wake cycles but no awareness of self or environment.
Neurology, 1989;39, 125125-126
Coma – profound unconsciousness caused by
disease, injury or sleep
• 210 patients with anoxic brain injury post arrest
• 134 (64%) died in the first week
• 27 (13%) were discharged to free living
• All but four improved by two weeks
- Levy, et al JAMA May 1985
Patient Preferences
• Competence – “A sufficiency of means for the
necessities of life”
– Legally is court determined
• Capacity – “The faculty for treating, experiencing
or appreciating”
Clinical judgment
Specific to making medical decisions
Medically “incapable” of decision
Terri did not have capacity
10
Surrogate Decision Makers
Who chooses if no documentation exists?
Spouse, Adult Children, Parents,
Siblings, 2nd, 3rd
• Substituted judgment
Knowledge from the patient
Knowledge about patient
Patient’s best interest
Quality of Life
Futility
“Leaky, hence untrustworthy, in vain:
The Schiavo Case
1- Medical Indications
- No chance for improvement
2- Patient Preferences
-Legal Precedent with Husband
3- Quality of Life
Quantitative Futility
Likelihood that a medical intervention will achieve its desired
ends falls below a threshold considered minimal
1%-- but beware cost considerations
1%
failing of the desired effect through an intrinsic defect”
Focus is on intervention not patient, society or other factors
Qualitative Futility
Whenever a man suffers an ill which is too strong for the
means at the disposal of medicine, he surely must not even
expect that it can be overcome by medicine
Quality of outcome associated with an intervention falls well
below a threshold considered minimal
Value laden and threshold debatable

Pope John Paul II, March 2004
“The sick person in a vegetative state, awaiting
recovery or natural end, still has the right to
basic health care (nutrition, hydration,
cleanliness and warmth).
Administration of water and food, even in
artificial means, ..is natural, not a medical act.
…should be considered ordinary and
proportionate care.”
Legal- PVS statutes
• 1976- Karen Ann Quinlan- post OD
– NJ Supreme Court- “if there is no reasonable possibility
returning to a cognitive, sapient life,” life sustaining
treatment can be removed.
– Here asc with ventilators
– Began “living will” movement
• 1990- Nancy Cruzan- post MVA
– Cruzan vs. State of Mo.
– US Supreme Court- Tube feedings can be stopped if
surrogates produced “clear and convincing evidence”
that she would refuse.
– “no legal distinction between artificial food/fluids and
other interventions (ventilators).
Politics
• Then President Bush. "I urge all those who honor Terri
Schiavo to continue to work to build a culture of life,
where all Americans are welcomed and valued and
protected especially those who live at the mercy of
others.”..
• Florida's governor, Jeb Bush, "Her experience will
heighten awareness of the importance of families dealing
with end-of-life issues, and that is an incredible legacy."
