Learning from disaster: 
patient safety and the role of oncology nurses.

When the Oncology Nursing Society (ONS) was almost exactly half its present age, in November 1994, a Boston Globe health columnist named Betsy Lehman was admitted to the Dana-Farber Cancer Institute in Boston, Massachusetts, to receive an investigational regimen for breast cancer. Her treatment ended in disaster. In one of the most notorious patient safety failures of modern times, Lehman was given severe overdoses of cyclophosphamide during a four-day period. On each of those four days, nurses, physicians, and pharmacists at Dana-Farber failed to notice that Lehman was receiving doses four times greater than the intended amount (Aspden, Wolcott, Bootman, & Cronenwett, 2007). Lehman died of cyclophosphamide toxicity on December 3, 1994.
