Prospective Patient Optimisation – Predicting and Managing Risk of Harm Pre-Operatively

Assessing pre-operative risk for a patient is incredibly complex. The risks of mortality and complications change radically with differences in physiological variables and the severity of the operation being planned.

Clinicians use our COMPASS system to derive individualized risks of complications and mortality in less than a minute.

Patients unsuitable for operation can be identified and optimized before their hospital visit.

More informed decisions can also be made in the hospital on whether to operate on or optimize the patient.

A detailed output report can be signed by patients, supporting truly informed consent.

Targeted, precision care minimizes the risk of post-op complications, saving money and avoiding harm or mortality.

Compass provides prospective management of patients based around individualized assessment.

To illustrate how complex assessing risk can be, let’s consider a 56-year-old patient whose risk for a given (urological) operation varies 10-fold with only two variables varying from normal levels.

Unlike a lot of data applications, our systems are delivered Software as a Service can be available in a matter of hours and require zero integration or workflow changes, and even better, hospitals don’t have to hire additional staff to use or manage them.

The system helps with hospital issues, including:

  • Should the operation really have gone ahead?
  • Are high-risk patients being denied operations because surgeons are concerned about their ‘stats’?
  • Higher complications, mortality, and readmissions than necessary.
  • Increased operational expenses to manage avoidable harms.
  • Beds and resources blocked by patients who could have avoided harm.
  • Significant complaints or clinical negligence impact.
  • Patients who are not able to provide truly informed consent.

How does it work?

A clinician uses Compass to enter information for a patient (approximately one minute). The app is web-based, so integration is very simple. Reports are seen on the device and can be printed out, as shown below.


A personalized assessment of risk supports a truly informed discussion with the patient and enables effective decision-making on the next steps.

Personalized Assessment of Risk

Highly accurate risk predictions for mortality and complications.

Triage of Patients by Doctors

Provides an auditable record that the risks have been understood by the patient.


Individualized patient risk analysis supports decisions on optimization for better outcomes before a referral or in the hospital prior to an operation.

Reduce Harm and Mortality

Hospitals can manage the patient’s individualized complication risks to reduce avoidable harm, mortality, associated costs, and operational complexity.

Simple & Powerful

Surgical assessments completed in around a minute and reports generated there and then.


Based on learning over 30 years, 120 million patient records, data from 46 countries, inputs from 300 hospitals, operation in 11 countries.
