If the prochoice movement stopped trying to demonize centers that provide women with alternatives to abortion, fewer would wind up in the hands of careless abortionists, though it would also help if they started holding NAF accountable for its failure to ensure that its own standards are actually practiced at member facilities.
On July 9, 1916, 27-year-old homemaker Mina Mallett died at Chicago's Washington Park Hospital from septic infection caused by an abortion perpetrated on June 8. I've been unable to find any other information about Mina's death so I can't offer any speculation on preventability factors.
Note, please, that with overall public health issues such as doctors not using proper aseptic techniques, lack of access to blood transfusions and antibiotics, and overall poor health to begin with, there was likely little difference between the performance of a legal abortion and illegal practice, and the aftercare for either type of abortion was probably equally unlikely to do the woman much, if any, good. In fact, due to improvements in addressing these problems, maternal mortality in general (and abortion mortality with it) fell dramatically in the 20th Century, decades before Roe vs. Wade legalized abortion across America.
