Questions about Dr. Shafer in general
這篇是關於Dr. Shafer的相關問題
MJJC: Since your father passed away during the trial, was it hard to do the
testimony? (and please accept our most sincere condolences for your loss)
Dr. Steve Shafer: I’ve shared with some members of the MJJCommunity my
personal story about my father’s passing. I’ll spare you the details, other
than to say that for me, the trial brought me an unexpected gift: the chance
to be with my father when he died. Had it not been for the trial, I would
have been in New Jersey. As it was, I was at his bedside, offering love and
morphine. (I can only hope that one of my kids decides to take up a career in
anesthesia.)
During my testimony, I felt that my father was beside me. It gave me
confidence, particularly during cross examination. I knew that since my Dad
was with me, I’d be OK.
MJJC: During testimony we learned that you drank Propofol. Did you drink it
before you conducted the scientific research? What prompted you to drink it
yourself?
Dr. Steve Shafer: I knew that the defense would reject animal studies as not
applying to humans, just as Paul White did when asked about animal studies of
propofol in urine. There is no way that I could conduct a human study in the
US in three months, so I thought the best evidence I could get was to simply
drink propofol and report if it had any effects. I knew the pharmacology well
enough to be absolutely certain it was inert.
About a week later my colleague Pablo Sepulveda in Chile told me he would be
able to conduct a clinical trial in volunteers. That made my drinking
propofol completely irrelevant.
However, please remember that propofol is unique in the complete “first pass
” metabolism. One should not try this with other drugs. Indeed, many drugs
on the anesthesia cart would be fatal if consumed like that. This should not
be attempted as a party trick!
MJJC: Any comments on Mr. Chernoff referring to you as a "cop"?
Dr. Steve Shafer: No, that’s his job. It didn’t bother me at all.
MJJC: During your cross examination Defense asked "Are you aware that
everything you said here was your merely your opinion?" In your answer you
concluded that this was an interesting question- where does 'personal
opinion' end and where does "Dr. Shafer" begin? So did you, Dr. Shafer, come
to any conclusion in this conundrum? Do you consider it wise or even
desirable to split your mind in the Dr. figure- and Steven Shafer? Is it even
possible to do so? What would the result most likely be? Could there be
considerable "strength" in a personal, honest opinion?
Dr. Steve Shafer: I thought about that question quite a bit afterwards. I was
not expecting it, probably because I am not an experienced expert witness.
This was only the second time I have testified in court.
Mr. Chernoff was playing to my scientific training. Scientists are reluctant
to state that something is a certain fact. There is evidence, and
conclusions, but science is always open to new evidence and new conclusions.
His asking me “wasn’t your testimony entirely your opinion” was an
invitation to say “yes”, based on my interpreting “your opinion” as
referring to my scientific opinion. If I had answered “yes,” it would have
opened the door for him to say in his closing statement “Dr. Shafer himself
admitted that his views were just his opinions.” That would play to the
common use of “opinion” as mere speculation unsupported by data.
There were two aspects to my testimony: standard of care, and propofol
pharmacology. I need to discuss fact vs. opinion for these separately.
Many aspects of the “standard of care” have been codified by organizations.
For example, the American Society of Anesthesiologists has practice
guidelines that very clearly spell out the standard of care during
administration of anesthesia. My testimony was based largely on those
guidelines. One could argue that it was merely my “opinion” to represent
the published guidelines of the American Society of Anesthesiologists as
fact. However, it is a fact that they have published guidelines on the
standard of care, and those published guidelines were the basis of my “
opinion.”
There are aspects of the standard of care are not covered by published
guidelines because they are self-evident. I believe doctors should not lie. I
believe Conrad Murray’s misrepresentation of the drugs that he gave to
Michael Jackson was an unconscionable violation of the standard of care. Is
it my opinion? Yes. However, I think every person on the planet shares my
opinion that a doctor should not lie. Similarly, it is my opinion that
doctors must place the interest of their patients ahead of their personal
interests. That is my “opinion.” However, again I think it is an opinion
that is universally shared. Can that be dismissed as “mere opinion?”
Regarding the scientific part of the testimony, my “opinion” is that of an
expert in the field. The simulations I presented were mathematically accurate
representations of the pharmacokinetics. Baring a mathematical error on my
part, the simulations show exactly the blood and effect site propofol
concentrations predicted by specific pharmacokinetic models for specific
doses. The “expert” aspect is to decide what doses should be simulated, and
whether these are likely scenarios. I did a lot of simulations, and even
shared with the defense my spreadsheets so that they could do simulations as
well. I chose some over others based on data. That is an “expert opinion.”
However, it is more scientifically precise to say “conclusion, based on the
data” that to call it “opinion”, since the latter implies uninformed
speculation.
MJJC: Did it amuse you like it did many when Dr. White was called "Dr.
Shafer" several times in court by Prosecution, Defense and even the Judge?
Dr. Steve Shafer: Yes. I think everyone was amused.
MJJC: Have you met any of the Jackson Family before, in between or after the
trial? If so did they ever asked you any medical questions?
Dr. Steve Shafer: I spoke with them briefly several times walking to or from
the courtroom. They were very kind, and offered condolences on the death of
my father. I shared that we both had suffered loss, and offered condolences
in return. I appreciated their kindness.
MJJC: Did your life change after this trial? If yes, positively or negatively?
Dr. Steve Shafer: I learned a huge amount from the trial, including:
‧ A lot about the pharmacology of propofol and lorazepam (I did a LOT of
reading to educate myself on the issues, and to respond to claims made by the
defense).
‧ Something about how the criminal justice system works. I was impressed by
what I saw. In particular, the office of the District Attorney was absolutely
honest and transparent. This was not a “game.” It was an attempt to
determine the truth.
‧ Different approaches to discerning truth. In science, “truth” is
determined by experiment, observation, peer review, and the ever-questioning
nature of science. In science, the burden of proof is on the person making
the claim. In criminal law, “truth” is determined by a jury that arrives
knowing almost nothing, the exact opposite of peer reviewers. In criminal
law, the burden of proof is on the prosecution. The defense can assert
anything without evidence. I learned that both systems work.
I have received wonderful feedback from my professional colleagues. It won’t
change me, but it has been rewarding.
I have had very kind letters from the Michael Jackson community. I did not
expect these, but they have been appreciated.
MJJC: What do you think about Michael Jackson fans love and appreciation
towards you? Do you know that many fans publicly express their love and
gratitude to you, and use your pictures and quotes to express themselves?
What do you think about that?
Dr. Steve Shafer: It didn’t expect it! However, I do understand that not
knowing what happened to Michael Jackson has been a cause of considerable
pain to his millions of fans. If my testimony was helpful, and perhaps
brought a closure to his passing so they can again focus on his music and
message, then I’m honored to have had the opportunity.
I have tried to answer many of the e-mails I have received. I am appreciative
of the kind comments I have received from his fans all over the world.
MJJC: Now that the trial is over what’s next for Dr. Steve Shafer? Returning
to practice? Teaching? Patient education and advocacy?
Dr. Steve Shafer: All of the above.
I did not watch the first two days of Paul White’s testimony, because I was
back in the operating rooms at Columbia University giving anesthesia. I love
clinical anesthesia. I love taking care of patients. We all need to define
who we are. For me, it’s simple: I’m a doctor. I care for patients. If I
ever stop caring for patients, I won’t know who I am. That’s what I do.
Having said that, my work as Editor-in-Chief of Anesthesia & Analgesia
requires about 60 hours per week. Even during the trial I would go home and
read a dozen new submissions every night, assign editors and reviewers, and
process another dozen decision letters. I will be doing that every day until
my term as Editor-in-Chief ends in 2016.
I continue to teach. You will get a laugh at the most recent lecture I have
given at Columbia: the role of clinical pharmacology (e.g., pharmacokinetics)
in the trial of Conrad Murray.
Anesthesia & Analgesia is the largest medical journal in the field of
anesthesiology. I use Anesthesia & Analgesia as a platform to advocate for
patient education, patient care, and patient safety
(http://www.anesthesia-analgesia.org). Only rarely does that involve my own
writing. The Journal advances patient care through editorial policies
anchored in doing what is best for patients.
I continue to pursue my own research, primarily modeling the behavior of
drugs used in anesthesia. Much of this is now in collaboration with my wife,
Pamela Flood, who is the chief of Obstetrical Anesthesia at the University of
California in San Francisco.
I am actively involved in developing new drugs to improve the safety of
anesthesia and pain management. In 2003 I co-founded a biotech company to
develop better drugs for anesthesia and pain management. You can find it at
http://www.pharmacofore.com. Our work is progressing well, and this also
consumes some of my attention.
MJJC: How the medical community has responded/reacted towards you since your
testimony?
Dr. Steve Shafer: The response has been uniformly positive. There has been
considerable appreciation that I spoke for the values that physicians hold,
as well as for clearly explaining the medical and scientific issues involved.
I didn’t testify to garner any attention or recognition, and it makes me a
little uncomfortable. However, the validation of my testimony from my medical
colleagues has been affirming that I did the right thing.
MJJC: Did media approach you for interviews? If yes, why didn’t we see you
on TV?
Dr. Steve Shafer: Yes, I was approached, but I don’t think the interviews
were aired. I think the reason is that they didn’t like my answers. I was
asked about what I thought Conrad Murray’s sentence should be. I answered
honestly that I didn’t have the background to judge that. I said that our
lawmakers determine the appropriate sentences for criminal behavior, and
judges then impose sentences based on the dictates of the law. I said that
this was really a question for Judge Pastor, who IS an expert. I don’t think
they liked that answer. They probably hoped for something much more vengeful
from me.
I was asked how I felt about my role in convicting Conrad Murray. I honestly
replied that I don’t think I had much of a role. Conrad Murray gave Michael
Jackson propofol in a bedroom, with no training, no monitoring, no backup, no
accountability, abandoned him to talk on the phone, and then lied about his
action. His guilt was obvious when the facts emerged in 2009, and it just as
obvious after my testimony.
MJJC: One of the most shocking parts of Dr. White’s testimony was when he
admitted that he had not fully reviewed the current scientific literature on
Propofol. Under cross-examination he also admitted that had not completely
read the journal articles that were used to create the Propofol simulations
that he presented as the basis of his court testimony. As a scientist I found
this to be extremely irresponsible professional behavior. Can you please
discuss how you prepared for your testimony in this trial?
Dr. Steve Shafer: I spent dozens, and perhaps hundreds, of hours in
preparation. I read well over 100 papers. I analyzed the data numerous ways,
and even made my spreadsheets available to the defense. I did the “heavy
lifting” that is expected of an expert. This isn’t unique to this case – it
’s how I approach everything I do.
MJJC: Judge Pastor picked out Murray's recording of MJ as the piece of
evidence that affected him the most during the trial. Was there any one thing
that affected Dr Shafer in all the evidence that he looked at?
Dr. Steve Shafer: Yes, the consistency Conrad Murray’s behavior. In the
sentencing hearing Judge Pastor outlined in detail Conrad Murray’s pattern
of repeated lying, self-serving actions, and reckless disregard for the
wellbeing of his patient. That was what I saw also.
MJJC: How did you decide to choose your profession? What did it start with?
Dr. Steve Shafer: Many physicians choose a medical career very early in life.
I knew from the time I was 9 years old that I wanted to be a physician. The
inspiration was my pediatrician. He seemed to know absolutely everything, and
I was amazed at the breath of his knowledge. Additionally, every year he
spent several months on the “Ship Hope” practicing medicine in third world
countries. I profoundly admired his sense of service to others. That was my
role model
MJJC: Did any of your parents relate to medical sphere?
Dr. Steve Shafer: I am the first physician in my family. My father was a
management consultant, and my mother was a housewife. Both of them took pride
in having a son who went to medical school. I became the family resource for
all medical questions.
MJJC: Did your father know about your intention to take a stand in Conrad
Murray's trial? If yes, what were his thoughts about it, if any?
Dr. Steve Shafer: Yes. He liked it a lot. He told me it made him proud. He
was also aware that I was visiting him every day because I was in Los Angeles
for the trial.
He watched my testimony on Thursday morning, and died that evening.

In a world filled with hate, we must still dare to hope.
In a world filled with anger, we must still dare to comfort.
In a world filled with despair, we must still dare to dream.
In a world filled with distrust, we must still dare to believe.
