CASE STUDY OVERVIEW:

Ignaz Semmelweis (.wikipedia.org/wiki/Ignaz_Semmelweis”>http://en.wikipedia.org/wiki/Ignaz_Semmelweis ) was the head of
obstetrics in 1846 at Vienna General Hospital
That year, 459 women
died from childbed fever in one of the Divisions at the hospital (Table
1).
His goal (and yours!) is
to determine the cause of this disease.

A FEW EXTRA PIECES OF
INFORMATION:

The hospital had two divisions:
1 and 2
Division 1: Doctors
and medical students delivered babies (after doing autopsies in the morning)
Division 2: Midwives
delivered babies
In Division 2,
mortality rates were much lower
Around the same time,
one of his colleagues died of a massive infection, he was able to determine
the cause through an autopsy of childbed fever
This colleague was
stuck in the finger by a scalpel during an autopsy on a woman who died of childbed
fever
