Why a Doctor Would Be Relieved When a New Study Fails To Reduce Deaths
Sometimes the New England Journal of Medicine reads like a journal of failed bright ideas. I do not remember ever having read of so many failed trials of treatment as I have recently, but perhaps that is a sign of increasing scientific honesty. After all, it is as important to know what does not work as what does, especially when what does not work is very expensive to administer.
Septic shock is a condition of dangerously low blood pressure brought about by serious infection. About 750,000 cases a year are treated in the United States alone, with a death rate above 20 percent, that is to say at least 150,000 people die of it each year. This is a number well worth reducing.
More than a decade ago the results of a trial were published in which it was shown that aggressive treatment according to a pre-arrange protocol could reduce the death rate from septic shock by about a half. In those days (medicine 10 years ago seems that of a bygone era), the death rate in septic shock was much higher than it is today, which may in part explain the success of that trial compared with the failure of a more recent trial published recently in the NEJM.
