Risk Prediction Tools

A number of scoring systems can be used in combination with CPET data to optimize/individualize perioperative risk evaluation and so contribute to consent and collaborative decision making:

  • Website providing life expectancy data from ONS and other pre-operative risk models including possum


  • SORT - Surgical outcome

    The SORT is a pre-operative risk prediction tool for death within 30 days of surgery. It has been developed and validated for use in inpatient non-neurological, non-cardiac surgery in adults (aged 16 or over).
    This web resource is the result of a collaborative effort between NCEPOD researchers (Karen Protopapa and Neil Smith) and doctors in anaesthesia and intensive care medicine who are part of the SOuRCe team (Ramani Moonesinghe and Jo Simpson).

  • NSQIP - American College of Surgeons National Surgical Quality Improvement Programme

    The ACS Surgical Risk Calculator estimates the chance of an unfavorable outcome (such as a complication or death) after surgery. The risk is estimated based upon information the patient gives to the healthcare provider about prior health history. The estimates are calculated using data from a large number of patients who had a surgical procedure similar to the one the patient may have.
