COMPASS – Prospective patient optimisation – predicting and managing risk of harm pre-operatively

COMPASS provides prospective management of patients based around individualized assessment

Assessing pre-operative risk for a patient is incredibly complex.  Risks of mortality and complications change radically with differences in physiological variables and the severity of 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 hospital on whether to operate 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/mortality.

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

Combinations for ALL operative types and key physiological variables to consider

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 as surgeons are concerned about their ‘stats’?
  • Higher complications, mortality and readmissions than necessary
  • Increased operational expenses to manage avoidable harms
  • Beds and resources blocked with patients that could have avoided harm
  • Significant complaints/clinical negligence impact
  • Patients 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 personalised assessment of risk supports a truly informed discussion with the patient and decision making on steps forward

Personalised 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.


Indivisualised patient risk analysis supports decisions on optimisation for better outcomes before a referral or in hospital prior to an operation

Reduce harm and mortality

Hospital can manage the patient’s individualised complication risks to reduce avoidable harm, mortality and 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.
