Multicenter Study
Are targeted preoperative risk prediction tools more powerful? A test of models for emergency colon surgery in the very elderly.
Whether preoperative risk prediction improves with the use of more patient- and procedure-targeted models is unclear. We created a customized preoperative mortality risk prediction score for patients 80 years or older needing an emergency colectomy and compare it with existing, more generic risk assessment methods. ⋯ Our study presents a validated preoperative mortality score for very elderly patients needing an emergency colectomy. The greater discriminating power of this targeted score indicates that preoperative risk assessment may need to be customized to specific procedures and patient circumstances.
