Using logistic regression for assessing the probability of serious postoperative complications after colorectal operations in geriatric patients

This paper focuses on an analysis of data from elderly patients (aged 65 and older) who underwent an elective operation of colon or rectum in the years 2001–2009 at the Department of Surgery of the University Hospital Ostrava. The main purpose is to determine the main risk factors leading to serious postoperative complications or even death in consequence of the operation. Our results will serve as a foundation for creating a reliable predictor model that will assess the overall health of the patients and the potential benefits (and risk) of the operation, leading to a reduction in incidence of serious postoperative complications of the operation and an improvement in the quality of life for the seniors. For the primary analysis we used the logistic regression methodology.
