Could it be acceptable for the BMJ to continue to employ a statistical
adviser who was to give evidence on behalf of the tobaccoindustry?
We faced this problem a few years ago with Ken MacRae,who died
earlier this year (27 April, p
1041. Despite being veryfond of Ken, our gut reaction was no. We
feared the headline:"BMJ adviser paid by tobacco industry."
But then we thought thatperhaps statisticians could be like lawyers:
legitimately paidto advance an argument in Britain's adversarial
legalsystem.
Our traditional solution to ethical conundrums is to publish the problem and
then trust to the wisdom of our readers. Thisis not copping out.
It's a belief in dialectic and our readers.Ken was happy for us to
publish, but the tobacco company lawyerssaid no. We agreed with Ken
that he should go, which was a greatpity because he had an
unequalled ability to explain complicatedstatistics and make you
laugh at the same time. He could alwaysmake the fog clear, at least
for a moment. "Consider," he wouldsay, "the proof that running up
Ben Nevis is the best treatmentfor myocardial infarction. The
25 patients who completed the treatmentall survived 10 years. But
you mustn't forget the 25 who refusedthe treatment, the 25 lost on
the mountain, and the 25 who diedwhile running." Now you understand
the necessity of an intentionto treatanalysis.
Ken features prominently in David Skegg's editorial on the recent legal case
where the judge decided against women who believedthat they had been
harmed by third generation contraceptive pills(p
504). He gave evidence on behalf of the drug companies (ashe
usually did), and the judge was particularly impressed by his
evidence. The judge declared that his own "familiarity with algebra
lay in the past and at an elementary level." In other words, heknew
less statistics than the average BMJ editor. No wonder hewas
impressed by Ken. Skegg thinks that the millions spent onthe case
was moneywasted.
An ethical conundrum familiar to every doctor is when to accept gifts from
drug companies. The Royal College of Physicianshas just updated its
guidance, which is full of words like "modest"and "reasonable" (p
511). John Collins, joint author of the guidelines,says that
"inappropriate relationships with business are muchless likely than
in the 80s." I'd like to see his evidence forthat. He continues: "I
suspect that the vast majority of practisingphysicians do not
prescribe medicines because a company has fundedthem to go to, say,
the American Thoracic Society conference.However if you were a
non-medically qualified individual lookingat a doctor you might
wonder whether they would be influencedin any way." In other words,
only a naïve patient would believethat a doctor would be influenced
by a business class return toSan Francisco and a week in the best
hotel. We doctors knowbetter.
