Abstract

The objective of this thesis was to develop two risk scores which could predict the individual risk of in-hospital mortality for patients with flail chest using data from the Ontario Trauma Registry. The first study describes the univariate analyses conducted to identify mortality predictors. The second study details the logistic regression analysis that generated a risk score. Finally, the third study describes the decision tree analysis that produced the second risk score. The two risk scores were then compared.

In summary, these three studies show that a minority of flail chest patients are currently undergoing operative repair and that a risk score may be a useful adjunct for surgeons to determine the individual risk of in-hospital mortality in patients requiring operative repair for flail chest.
