title: TI-59 programmable calculator program for calculating predicted operative mortality in general surgery.
abstract: A program for the TI-59 programmable calculator for calculating predicted postoperative mortality is presented. Input data are based on handy, clinical, non-invasive pre-operative and operative parameters retrieved mostly significant in this respect by former multivariate logistic regression analysis of a broad data-base; their relative weights are incorporated into the program data base as basic coefficients. Considerations employed in its usage are discussed, as well as possible future technical and/or environmental modifications.
