What factors affect operative mortality and long-term survival in heart surgery?

Michael Chui, in the Department of Statistics and Actuarial Science, successfully defended his thesis "Nonparametric Simultaneous Modelling of Operative Mortality and Long-Term Survival After Coronary Artery Bypass Surgery."

Past analyses have looked at the factors that affected post-operative mortality or long-term survival separately - Michael's thesis looked for factors that affected both simultaneously. In his thesis, he proposes a new technique (using easily understood and commonly used methodology) that health researchers can utilize to identify prognostic factors. It has applications in all areas of health research including cardiovascular disease and cancer.

This type of interdisciplinary work is a hallmark of of our program in Applied Statistics at Simon Fraser University.
