“This excellent result had, of course, nothing to do
with the therapy they received or my clinical skills.
It demonstrated, on the other hand, very clearly the
relative unimportance of therapy in comparison
with the recuperative powers of the human body.”

Archie Cochrane
• Soviet POW who was dying in great pain. He was screaming and Archie had no drugs to help.
• Instinctively, Archie sat on the bed and took the Russian in his arms.
• The effect was almost magical, the Russian quietened at once and died peacefully a little later.

Archie Cochrane
• Archie C believed his personal
intervention he had improved this
soldier’s quality of life/dying very
dramatically, even though he did not
affect the final outcome.

“I believe that cure is rare while the need for
care is widespread, and that the pursuit of
cure at all costs may restrict the supply of
care...”
Archie L Cochrane, 1972, p7

Archie Cochrane
• He began to Q the effectiveness of the care/treatments he offered. Did they actually worked?
• He became convinced of the importance of RCTs in assessing whether a form of care/treatment worked or not.

“It is surely a great criticism of our
profession that we have not organised a
critical summary, by speciality and
subspeciality, adapted periodically, of all
relevant randomised controlled trials”
Archie L Cochrane, 1979
