Introduction
The purpose of these pages is to provide surgeons with the ability to calculate a CR-POSSUM score for their colorectal surgical patients online to enable them to provide further information on mortality risk. There is also a wealth of general information on risk prediction in surgery - this area of the site is constantly being updated and it is worth checking back on a regular basis. The service described above is provided free of charge with no liability attached (see disclaimer).
Calculate a CR-POSSUM Score
Choose a value in each category that matches your patient from the drop down lists in both the physiological and operative parameters tables below. Default values (the lowest score) are shown for each category. Simply submitting the form as it is without changing the values (i.e. a young fit patient having a minor operation) still gives a v.small % risk for mortality. The more 'risky' the procedure the more accurate is the predicted risk calculated below.
